1. Introduction

The 21st century has witnessed an extraordinary global demographic transformation characterized by increasing life expectancies across most populations. This longevity dividend, while a testament to advancements in public health and medicine, simultaneously brings with it the escalating challenge of managing chronic diseases in an aging populace. Among these, Human Immunodeficiency Virus (HIV) stands as a particularly salient example. Historically a rapidly progressing, fatal illness, HIV has, through the advent and widespread adoption of highly effective antiretroviral therapy (ART) since the mid-1990s, undergone a remarkable metamorphosis into a chronic, manageable health condition. This therapeutic revolution has profoundly extended the lifespan of PLWH, leading to an unprecedented demographic shift within the HIV epidemic itself.

Globally, the number of older adults living with HIV has surged dramatically. In high-income countries, it is now estimated that over half of the HIV-positive population is aged 50 and older, with this proportion projected to grow further [1]. For instance, in the United States, data indicates that more than 50% of PLWH are in this age bracket, signaling a critical and urgent need for healthcare infrastructures to adapt to the unique and complex needs of this cohort [2]. Similar trends are evident across Europe, where the median age of PLWH continues to rise, and increasingly in low- and middle-income countries (LMICs), particularly in sub-Saharan Africa, where concentrated efforts in ART rollout have led to significant increases in survival rates among populations living with HIV from early in the epidemic [3].

Older adults living with HIV often navigate a intricate landscape of co-existing conditions, which extends beyond the direct effects of the virus and its treatment to include common age-related comorbidities that appear to manifest earlier and with greater severity in this population. These include accelerated cardiovascular disease, chronic kidney disease, osteoporosis and bone fractures, various malignancies, and neurocognitive disorders [4]. The management of these multiple conditions inevitably leads to polypharmacy, increasing the risk of adverse drug reactions and complex drug-drug interactions, particularly with antiretroviral medications. Furthermore, this demographic frequently grapples with a distinct constellation of psychosocial challenges, such as heightened social isolation, persistent HIV-related stigma, mental health issues (including depression, anxiety, and trauma from past experiences of the epidemic), and economic instability [5].

These multifaceted challenges necessitate a fundamental re-evaluation and adaptation of existing healthcare delivery models. A comprehensive, integrated, and patient-centered approach is no longer merely advantageous but an absolute prerequisite for ensuring optimal health outcomes and enhancing the quality of life for older PLWH. This report embarks on a detailed examination of the essential components that underpin effective geriatric HIV care models. It then critically analyzes the significant challenges that hinder their widespread and equitable implementation, drawing upon empirical evidence and clinical observations. Finally, it proposes forward-looking strategies and future directions to enhance care delivery, foster innovation, and build a more resilient and responsive healthcare system capable of meeting the evolving needs of this unique and growing population.

2. Essential Components of Geriatric HIV Care Models

Effective geriatric HIV care models are not merely extensions of standard HIV or geriatric care; rather, they represent a synergistic integration of principles from both disciplines, augmented by a deep understanding of the unique interplay between HIV, aging, and social determinants of health. Such models are characterized by several interdependent and mutually reinforcing key components:

2.1. Comprehensive Assessment

A foundational element of high-quality geriatric HIV care is a holistic and comprehensive assessment that extends far beyond a typical medical history and physical examination. This evaluation must systematically encompass the patient’s biological, psychological, and social dimensions to construct a truly personalized and proactive care plan. This includes:

• Geriatric Syndromes Screening: Proactive identification of common geriatric syndromes, which are multifactorial conditions that do not fit into discrete disease categories and often lead to significant morbidity and mortality in older adults. These include, but are not limited to, frailty (a state of increased vulnerability to adverse health outcomes), recurrent falls, urinary incontinence, and sensory impairments (such as vision and hearing loss). Standardized screening tools, like the Fried Frailty Phenotype or the Short Physical Performance Battery (SPPB), can be invaluable in identifying individuals at risk [6].
• Cognitive Function Evaluation: Given the higher prevalence of HIV-Associated Neurocognitive Disorder (HAND) across its spectrum (from asymptomatic neurocognitive impairment to HIV-associated dementia), and age-related cognitive decline, routine cognitive screening is crucial. Tools like the Montreal Cognitive Assessment (MoCA) or the Mini-Mental State Examination (MMSE) can provide initial insights, prompting further neuropsychological evaluation if deficits are detected. This evaluation helps tailor communication strategies, medication management support, and safety interventions [7].
• Mental Health Status Assessment: Older PLWH often experience elevated rates of depression, anxiety, and post-traumatic stress disorder (PTSD), frequently stemming from cumulative trauma related to the HIV epidemic, stigma, loss, and chronic stress. Validated screening instruments (e.g., PHQ-9 for depression, GAD-7 for anxiety) should be routinely employed, with positive screens leading to referral for psychological or psychiatric evaluation and intervention [8]. Substance use disorders, including alcohol and prescription drug misuse, also warrant specific screening due to their impact on adherence, comorbidities, and cognitive function.
• Functional Status Assessment: Evaluating a patient’s capacity to perform Activities of Daily Living (ADLs) such as bathing, dressing, and eating, and Instrumental Activities of Daily Living (IADLs) like managing finances, cooking, and using transportation, provides critical insight into their independence and need for support services. This informs decisions regarding home health services, assistive devices, and long-term care planning.
• Nutritional Assessment: Malnutrition, sarcopenia (age-related muscle loss), and unintentional weight loss are prevalent among older PLWH due to factors like chronic inflammation, polypharmacy-induced side effects, and socioeconomic challenges. Comprehensive nutritional screening and referral to a registered dietitian are essential to prevent and manage these issues, which significantly impact frailty and recovery from illness.
• Social Support Systems and Social Determinants of Health (SDOH): A detailed understanding of the patient’s living situation, social networks, financial stability, access to nutritious food, transportation, and legal needs is fundamental. SDOH profoundly influence health outcomes and adherence to care. Assessing these factors allows for targeted interventions, such as connecting patients to community resources, housing assistance programs, or legal aid services. The presence or absence of robust social support is particularly critical for older adults who may have lost partners or friends to AIDS-related illness or due to the natural aging process [9].
• Sexual Health Assessment: Despite age, sexual health remains a relevant aspect of overall well-being. Discussion of sexual activity, condom use, and sexually transmitted infection (STI) prevention is important to ensure comprehensive care and address potential ongoing risks.

By conducting such a comprehensive and systematic assessment, clinicians can identify areas of vulnerability, anticipate future needs, and proactively develop highly personalized care plans that address the individual’s unique constellation of challenges and strengths.

2.2. Integrated Care Pathways

The complexity of managing both HIV and age-related comorbidities necessitates highly coordinated and integrated care pathways. This approach moves beyond fragmented, disease-specific care to a cohesive model that recognizes the patient as a whole. Key aspects include:

• Horizontal Integration: This involves seamless collaboration and communication between HIV infectious disease specialists and other relevant medical specialists, such as geriatricians, cardiologists, nephrologists, neurologists, oncologists, and mental health professionals. Instead of patients navigating disparate appointments and specialist silos, integrated care aims for shared care plans, co-location of services where possible, and robust referral systems. For example, a cardiologist managing a patient’s heart failure should be aware of potential drug-drug interactions with their ART regimen, and vice-versa [10].
• Vertical Integration: This refers to coordination across different levels of care, including outpatient clinics, inpatient hospital settings, long-term care facilities, home health services, and palliative care. Transitions between these settings are often points of vulnerability for older adults, increasing risks of medication errors, missed appointments, and poor outcomes. Integrated pathways ensure continuity of care through robust discharge planning, timely communication, and clear delineation of responsibilities.
• Care Coordination and Management: A dedicated care coordinator or nurse navigator is often central to integrated care. These individuals serve as a central point of contact for the patient and their family, facilitating appointments, explaining complex medical information, ensuring follow-up on referrals, and addressing logistical barriers. They play a crucial role in harmonizing care across multiple providers and settings, effectively mitigating the risk of fragmented care and improving adherence to complex treatment regimens.
• Multimorbidity Management Strategies: Older PLWH frequently live with multiple chronic conditions. Integrated care pathways employ strategies to manage multimorbidity by prioritizing interventions, balancing competing treatment goals, and avoiding therapeutic duplication or contradictions. This often involves discussions about patient priorities, shared decision-making, and a focus on improving overall functional status and quality of life rather than solely targeting individual disease parameters.

The goal of integrated care pathways is to ensure that all aspects of the patient’s health are addressed in a cohesive, efficient, and patient-centered manner, thereby reducing healthcare burden, improving adherence, and optimizing health outcomes.

2.3. Multidisciplinary Team Approach

No single healthcare provider possesses the breadth of expertise required to address the intricate needs of older PLWH. Therefore, a collaborative multidisciplinary team (MDT) approach is indispensable. This team typically comprises a diverse group of professionals, each contributing their specialized knowledge to provide holistic and individualized care. The key members and their contributions include:

• Infectious Disease Specialists: Central to managing HIV infection, including ART selection, monitoring viral load and CD4 counts, preventing and treating opportunistic infections, and managing HIV-specific complications.
• Geriatricians: Crucial for their expertise in the aging process, geriatric syndromes (frailty, falls, cognitive impairment), polypharmacy, and functional decline. They can assess age-related vulnerabilities and help integrate HIV care with general geriatric principles [11].
• Pharmacists: Indispensable in managing complex medication regimens. They perform medication reconciliation, screen for potential drug-drug interactions (especially between ART and polypharmacy), identify inappropriate prescribing, optimize dosages based on age and renal/hepatic function, and provide crucial patient education on medication adherence and side effects. They can also lead deprescribing efforts to reduce unnecessary medications [12].
• Mental Health Professionals (Psychiatrists, Psychologists, Social Workers, Counselors): Address prevalent mental health conditions (depression, anxiety, PTSD), provide coping strategies, support cognitive rehabilitation efforts, manage substance use disorders, and offer counseling for grief, trauma, and stigma. Social workers also connect patients to essential social services.
• Social Workers: Beyond mental health support, social workers are vital in addressing social determinants of health. They assist with navigating complex healthcare systems, accessing financial aid, housing assistance, food security programs, transportation, and legal services. They also play a key role in advance care planning and connecting patients to community support networks.
• Nutritionists/Dietitians: Provide guidance on healthy eating, manage nutritional deficiencies, address sarcopenia, and support weight management, all of which are critical for maintaining strength, preventing frailty, and supporting overall health in older adults.
• Physical and Occupational Therapists: Essential for maintaining and improving functional independence. Physical therapists address mobility issues, balance, and falls prevention, while occupational therapists help patients adapt to daily activities, providing strategies and assistive devices to maintain independence in the home and community.
• Dentists: Oral health issues, including dry mouth, periodontal disease, and oral candidiasis, can be exacerbated by HIV and aging. Regular dental care is important for overall health and quality of life.
• Palliative Care Specialists: For older PLWH with advanced illness or significant symptom burden, palliative care specialists can provide comprehensive symptom management, discuss goals of care, assist with advance directives, and offer emotional and spiritual support to both patients and their families, independent of prognosis [13].

Effective MDT functioning relies on strong interprofessional communication, regular team meetings or case conferences, and a shared electronic health record system to ensure a unified approach to patient care.

2.4. Patient-Centered Care

At the heart of effective geriatric HIV care is a profound commitment to patient-centeredness, where the individual’s unique preferences, values, goals, and life circumstances guide all aspects of care. This approach fosters greater patient engagement, adherence, and satisfaction. Key elements include:

• Shared Decision-Making: Moving beyond a paternalistic model, shared decision-making actively involves the patient (and, where appropriate, their designated caregivers or family members) in all treatment choices. This entails providing clear, understandable information about treatment options, their potential benefits and risks, and alternative approaches. Clinicians then elicit the patient’s values and preferences, ensuring that decisions align with their life goals and quality of life priorities. For older PLWH, this is particularly important when balancing the management of multiple chronic conditions and potential trade-offs between aggressive interventions and comfort [14].
• Health Literacy and Communication: Given potential age-related cognitive changes or varying educational backgrounds, information must be communicated in an accessible and understandable manner. This includes using plain language, avoiding jargon, providing written materials, and employing visual aids. Ensuring patients comprehend their diagnosis, treatment plan, and self-management strategies is critical for adherence and empowerment.
• Cultural Competency and Humility: Recognizing and respecting the diverse cultural backgrounds, spiritual beliefs, sexual orientations, and gender identities of older PLWH is paramount. Cultural competency involves understanding how these factors influence health beliefs, care-seeking behaviors, and communication styles. Cultural humility, a lifelong commitment to self-reflection and learning, encourages providers to approach each patient with an open mind, acknowledge their own biases, and strive to understand the patient’s unique cultural context without making assumptions.
• Empowerment and Self-Management: Patient-centered care empowers individuals to take an active role in managing their health. This includes providing education on self-care techniques, medication adherence strategies, symptom management, and navigating healthcare systems. Fostering a sense of control over one’s health can significantly improve outcomes, especially in managing chronic conditions like HIV.
• Goals of Care Discussions and Advance Directives: Initiating early, sensitive, and ongoing conversations about a patient’s goals of care is essential for older adults. These discussions help clarify what matters most to the patient in terms of their health and life, particularly as they face complex medical decisions or declining health. Encouraging the completion of advance directives (e.g., living wills, durable power of attorney for healthcare) ensures that their wishes regarding medical treatment are respected, even if they later lose the capacity to make decisions themselves. This proactive approach supports patient autonomy and provides peace of mind.

By prioritizing the patient’s perspective and active participation, healthcare providers can build stronger therapeutic alliances, improve adherence to complex regimens, and ultimately enhance the overall quality of life for older PLWH.

2.5. Social Support Integration

The profound impact of social support on the well-being of individuals living with chronic conditions, including HIV, is well-documented [15]. For older PLWH, who may have experienced significant social losses due to the epidemic, along with age-related isolation, integrating robust social support into care models is paramount. This goes beyond merely referring to community resources and involves actively fostering and leveraging supportive networks:

• Peer Support Networks and Mentorship: Connecting older PLWH with their peers who share similar lived experiences can be incredibly powerful. Peer support groups provide a safe space for sharing challenges, coping strategies, and mutual encouragement, reducing feelings of isolation and fostering a sense of community. Mentorship programs, where long-term survivors guide newer diagnoses or those struggling, can also be highly effective in improving engagement and adherence.
• Family and Caregiver Involvement: Recognizing that family members or informal caregivers often play a crucial role in supporting older adults, care models should actively engage them. This includes providing education about HIV and aging, offering support for caregiver burden, and facilitating respite services. Understanding family dynamics and involving willing family members in care planning (with patient consent) can significantly enhance care delivery.
• Addressing Social Isolation and Loneliness: Specific interventions aimed at combating social isolation and loneliness, which are significant determinants of health, are vital. This could involve promoting participation in senior centers, volunteer activities, or specialized programs designed for older LGBTQ+ individuals or racial/ethnic minorities. Leveraging technology, such as video calls or social media, can also help maintain connections for those with mobility issues.
• Housing and Living Arrangements: Unstable housing or inadequate living conditions significantly impede health management. Integrating social workers who can connect patients to age-friendly housing options, assisted living facilities, or home modification services is crucial. For older adults who wish to age in place, support services that enable them to do so safely and comfortably are essential.
• Financial Support and Legal Aid: Many older PLWH face financial insecurity due to long-term disability, healthcare costs, or past discrimination. Connecting patients with resources for disability benefits, pension planning, or financial counseling can alleviate significant stress. Legal aid services can assist with wills, power of attorney, and addressing discrimination, ensuring their rights and wishes are protected.
• Community-Based Partnerships: Establishing strong collaborations with community-based organizations (CBOs), including those specializing in aging services, HIV support, LGBTQ+ services, and culturally specific programs, is key. CBOs often have deep ties within their communities and can provide culturally sensitive, accessible support that healthcare settings cannot replicate alone.

By actively integrating social support and addressing the broader social determinants of health, geriatric HIV care models can significantly enhance the well-being, resilience, and quality of life for older PLWH, moving beyond purely clinical interventions to encompass holistic human needs.

3. Challenges in Delivering Effective Geriatric HIV Care

Despite the clear recognition of the essential components of optimal geriatric HIV care, numerous formidable challenges impede its widespread and equitable delivery. These barriers are multifaceted, spanning logistical, pharmacological, psychological, social, and systemic domains, requiring concerted effort to overcome them.

3.1. Logistical Barriers

Older adults, especially those living with chronic conditions like HIV, frequently encounter significant logistical hurdles that impede their access to timely and appropriate healthcare services:

• Transportation Challenges: A primary barrier for many older adults is the lack of reliable and affordable transportation. Mobility issues, such as frailty, arthritis, or neurological conditions, may prevent them from driving or using public transportation. The cost of ride-sharing services or specialized medical transport can be prohibitive, leading to missed appointments, delayed diagnoses, and non-adherence to follow-up care [16]. This challenge is particularly acute in rural areas where public transport options are scarce and distances to specialized clinics are vast.
• Mobility Issues and Accessibility: Physical limitations associated with aging, such as reduced endurance, balance problems leading to falls, or reliance on mobility aids (walkers, wheelchairs), can make navigating large hospital complexes or multiple clinic visits extremely challenging. Clinics may lack accessible entrances, elevators, or adequate waiting areas, further deterring attendance. Even within clinics, the distance between departments can be daunting.
• Navigating Complex Healthcare Systems: Healthcare systems are notoriously complex, involving multiple specialists, varying insurance requirements, and intricate appointment scheduling processes. For older adults, particularly those with cognitive impairments or limited health literacy, navigating this labyrinth can be overwhelming and frustrating, leading to disengagement from care. The burden of coordinating multiple appointments with different providers, often at various locations, falls heavily on the patient or their caregivers.
• Digital Divide: While technological innovations (like telehealth) offer potential solutions, many older adults face a significant ‘digital divide.’ They may lack access to reliable internet, smartphones, or computers, or possess limited digital literacy to effectively utilize online patient portals, virtual appointments, or health-related apps. This can exacerbate isolation and limit access to health information and remote care options.
• Rural vs. Urban Disparities: Logistical barriers are often amplified in rural settings, where there are fewer healthcare providers, limited specialized services (including geriatricians and HIV specialists), and greater travel distances. This forces rural older PLWH to either forgo specialized care or endure significant hardship to access it [17].

Addressing these logistical barriers requires innovative solutions, including expanded transportation services, age-friendly clinic designs, simplified navigation support, and targeted digital literacy programs.

3.2. Polypharmacy and Inappropriate Prescribing

The simultaneous use of multiple medications, termed polypharmacy, is a pervasive and dangerous challenge in the care of older PLWH. While there is no universally agreed-upon definition, polypharmacy is often considered the concurrent use of five or more medications, with ‘excessive polypharmacy’ referring to ten or more. Given the high prevalence of comorbidities in older PLWH (e.g., cardiovascular disease, diabetes, hypertension, dyslipidemia, chronic kidney disease, mental health disorders), it is common for them to be prescribed numerous drugs in addition to their ART regimen [18].

• Consequences of Polypharmacy: The risks associated with polypharmacy are substantial and include:
  • Increased Risk of Adverse Drug Reactions (ADRs): The more medications a patient takes, the higher the likelihood of experiencing side effects, which can range from mild discomfort to life-threatening events.
  • Drug-Drug Interactions (DDIs): This is a particularly critical concern for older PLWH. Antiretroviral drugs, especially certain protease inhibitors and non-nucleoside reverse transcriptase inhibitors, are known to interact with a wide range of medications used for comorbidities (e.g., statins, anti-hypertensives, antidepressants, sedatives). These interactions can lead to dangerously high or low drug levels, compromising efficacy or increasing toxicity. For instance, some ARTs can significantly increase statin levels, leading to muscle damage [19].
  • Drug-Disease Interactions: A medication prescribed for one condition might worsen another existing condition (e.g., a beta-blocker for heart disease worsening asthma, or a sedative exacerbating cognitive impairment).
  • Prescribing Cascades: When a new symptom (e.g., dizziness, fatigue) arises due to a medication’s side effect, it is mistakenly identified as a new medical problem, leading to the prescription of another drug to treat that ‘new’ symptom, perpetuating a dangerous cycle.
  • Reduced Adherence: Complex regimens with multiple pills, varying dosing schedules, and side effects can make adherence challenging, leading to suboptimal treatment outcomes for both HIV and comorbidities.
  • Increased Healthcare Costs: Polypharmacy contributes significantly to medication costs, hospitalizations due to ADRs, and emergency department visits.
  • Impaired Cognition and Falls: Certain drug classes (e.g., anticholinergics, benzodiazepines, opioids) are particularly associated with cognitive impairment and an increased risk of falls in older adults.
• Inappropriate Prescribing: This refers to the prescription of medications where the potential harm outweighs the benefit, or when there is a safer, more effective alternative. Tools like the Beers Criteria (developed by the American Geriatrics Society) and the STOPP/START criteria help identify potentially inappropriate medications for older adults and encourage appropriate prescribing [20]. Examples include prescribing benzodiazepines for long-term anxiety, or certain anti-histamines due to their anticholinergic effects, which can worsen cognitive function.

Mitigation Strategies: Effective management of polypharmacy requires proactive strategies, including regular medication reviews by pharmacists or clinicians with geriatric expertise, deprescribing initiatives (systematic process of identifying and withdrawing problematic medications), and the use of integrated electronic health records with robust DDI alert systems.

3.3. Cognitive and Mental Health Issues

Cognitive and mental health impairments are disproportionately prevalent among older PLWH, adding layers of complexity to their care and significantly impacting their quality of life, adherence to treatment, and decision-making capacity:

• HIV-Associated Neurocognitive Disorder (HAND): Even with effective ART, PLWH can experience neurocognitive impairment. HAND exists on a spectrum, ranging from asymptomatic neurocognitive impairment (ANI), where cognitive deficits are present but do not affect daily function, to mild neurocognitive disorder (MND), where deficits impact daily life, to the most severe form, HIV-associated dementia (HAD). Older PLWH have a higher prevalence of HAND, likely due to chronic inflammation, long-term exposure to certain ARTs, and the interaction with age-related neuropathologies (e.g., cerebrovascular disease, Alzheimer’s pathology) [21]. HAND can manifest as issues with memory, attention, executive function, and psychomotor speed, affecting medication adherence, appointment keeping, and ability to manage finances.
• Depression and Anxiety: The prevalence of depression and anxiety is significantly higher in older PLWH compared to the general aging population. This is attributable to a confluence of factors, including chronic illness burden, cumulative grief and loss from the early epidemic, ongoing stigma, social isolation, financial strain, and biological effects of HIV and ART on the central nervous system [22]. Undiagnosed or poorly managed depression and anxiety can lead to poorer physical health outcomes, decreased ART adherence, reduced quality of life, and increased risk of substance use. It can also mask or exacerbate cognitive issues.
• Substance Use Disorders (SUDs): Alcohol and illicit drug use, as well as misuse of prescription medications, are persistent challenges. SUDs can interact negatively with ART, worsen comorbidities (e.g., liver disease, cognitive impairment), and impede adherence to treatment regimens. For older adults, SUDs may be long-standing issues or new onset reactions to stressors like social isolation or pain. Screening for SUDs and integrated treatment within HIV care are crucial.
• Impact on Self-Management and Adherence: Cognitive impairments can make it difficult for older PLWH to understand complex medication regimens, remember to take pills, or grasp the importance of regular clinic visits. Mental health issues can diminish motivation, energy, and self-efficacy required for consistent self-care. This necessitates tailored interventions such as medication reminders, pillboxes, simplified instructions, caregiver involvement, and direct mental health support.
• Assessment and Management: Regular screening for cognitive impairment and mental health conditions should be integrated into routine care. Management requires a multidisciplinary approach involving neuropsychological assessment, cognitive rehabilitation strategies, psychotherapy (e.g., cognitive behavioral therapy, supportive counseling), pharmacotherapy for mood disorders, and integrated behavioral health services within HIV clinics.

Addressing these intertwined cognitive and mental health issues is fundamental to improving adherence, functional independence, and overall well-being for older PLWH.

3.4. Stigma and Social Isolation

Stigma, particularly layered stigma, and profound social isolation remain deeply entrenched and pervasive challenges for older PLWH, significantly impacting their access to and engagement in care, as well as their overall quality of life [23].

• Layered Stigma: Older PLWH often contend with multiple, intersecting forms of stigma. Beyond the enduring HIV stigma (fear of contagion, moral judgment), they frequently experience ageism (prejudice against older individuals), and for many, stigma related to sexual orientation/gender identity (especially for gay and bisexual men, transgender individuals who comprise a significant portion of older PLWH). Additionally, some may face stigma related to substance use or racial/ethnic discrimination. These layers of stigma can lead to profound shame, secrecy, internalized self-blame, and a deep reluctance to disclose their HIV status to family, friends, or even healthcare providers, hindering the formation of supportive networks and transparent care [24].
• Consequences of Stigma:
  • Delayed Testing and Care-Seeking: Fear of discrimination or judgment can lead individuals to delay HIV testing or avoid seeking care even when symptomatic.
  • Non-Adherence to Treatment: Stigma can contribute to poor medication adherence if individuals fear accidental disclosure or feel unworthy of care.
  • Social Withdrawal and Isolation: The fear of rejection or judgment can cause older PLWH to withdraw from social interactions, leading to profound loneliness.
  • Mental Health Deterioration: Stigma is a major contributor to depression, anxiety, and low self-esteem.
  • Discrimination: Experiences of discrimination in healthcare settings (e.g., judgmental attitudes from providers, breaches of confidentiality) can erode trust and lead to avoidance of care.
• Social Isolation and Loneliness: This is a critical and growing concern for older PLWH. Many survived the peak of the AIDS epidemic, enduring the loss of partners, friends, and community, leading to profound grief and survivor’s guilt. As they age, natural processes such as the death of family members or friends, retirement, and reduced mobility further exacerbate social isolation. This lack of social connection has severe health implications, being linked to increased risk of premature mortality, cardiovascular disease, cognitive decline, and mental health disorders, comparable to the risks of smoking or obesity [25].

Addressing Stigma and Isolation: Combating stigma requires multi-level interventions: public education campaigns, anti-discrimination policies, provider training in cultural humility and sensitivity, and the creation of safe and inclusive spaces within healthcare settings. Addressing social isolation involves connecting patients to peer support groups, community centers, intergenerational programs, and leveraging technology to maintain social connections, alongside active efforts by social workers to build supportive networks around patients.

3.5. Healthcare Workforce Limitations

A significant systemic challenge is the existing shortage of healthcare providers adequately trained in both geriatric care and HIV medicine. This dual expertise is crucial for addressing the complex needs of older PLWH, and its scarcity creates critical gaps in service delivery [26].

• Shortage of Dual Expertise: There is a general shortage of geriatricians globally. Simultaneously, while infectious disease specialists are experts in HIV, their training often lacks a comprehensive focus on age-related physiological changes, geriatric syndromes, multimorbidity management, and complex polypharmacy specific to older adults. Conversely, geriatricians may lack in-depth knowledge of HIV-specific complications, antiretroviral pharmacology, and the unique immunologic aspects of HIV infection.
• Lack of Integrated Training: Medical education and postgraduate training programs often silo HIV care and geriatric care. Infectious disease fellowships may not include required rotations or extensive training in geriatric assessment, while geriatric fellowships might not adequately cover HIV management, specific ART toxicities, or opportunistic infections. This leads to a workforce that is either highly specialized in one area but lacking in the other, resulting in fragmented or suboptimal care for older PLWH.
• Provider Burnout: The complex needs of older PLWH, including their extensive medical comorbidities, psychosocial challenges, and frequent need for care coordination, can place a significant burden on healthcare providers. This complexity, coupled with high caseloads and inadequate resources, can contribute to provider burnout, leading to reduced quality of care and workforce attrition.
• Impact on Care Quality: The limitations in workforce capacity and expertise lead to several adverse outcomes: geriatric syndromes may be under-recognized or misattributed to aging, polypharmacy may be poorly managed, mental health issues may be overlooked, and care coordination can suffer. This directly impacts the ability to provide truly comprehensive and integrated care.

Addressing Workforce Limitations: Strategic investments are needed to enhance provider education and training. This includes developing interdisciplinary training programs, increasing funding for geriatric and HIV fellowships, integrating geriatric HIV content into standard medical curricula, and providing robust continuing medical education (CME) opportunities for existing clinicians. Team-based care models, where different specialists collaborate, can also help mitigate individual knowledge gaps.

4. Future Directions

To overcome the formidable challenges and enhance the quality of life and health outcomes for older adults living with HIV, a concerted, multi-pronged approach encompassing policy, community engagement, technology, research, and education is imperative. These future directions represent strategic investments in a healthier and more equitable future for this growing population.

4.1. Policy and Programmatic Initiatives

Translating best practices into widespread reality requires robust policy frameworks and dedicated programmatic initiatives. These efforts can create an enabling environment for integrated geriatric HIV care:

• National Strategies and Funding Prioritization: Governments and major health organizations must develop and implement national HIV/AIDS strategies that explicitly incorporate geriatric care principles and prioritize the needs of older PLWH. This includes dedicated funding streams for research, care models, and support services tailored to this demographic. For instance, the US National HIV/AIDS Strategy (NHAS) acknowledges the need to address the aging population, and specific initiatives should be funded to operationalize this recognition [27].
• Integration of Geriatric and HIV Care Guidelines: Policy should encourage the development and adoption of integrated clinical guidelines that seamlessly blend recommendations for HIV management with those for common age-related comorbidities and geriatric syndromes. These guidelines should be evidence-based and regularly updated to reflect new research and best practices.
• Incentivizing Integrated Care Models: Healthcare policy makers can create financial incentives and reimbursement structures that support multidisciplinary, integrated care models. This might include bundled payments for complex care, enhanced reimbursement for geriatric assessments, or incentives for clinics that demonstrate successful care coordination for older PLWH. Policies could also support co-location of services or telemedicine for integrated care.
• Interagency Collaboration: Fostering collaboration between health departments, aging services, housing authorities, social service agencies, and legal aid organizations is crucial. Policies should facilitate data sharing (with appropriate privacy protections) and joint planning to address the social determinants of health that profoundly impact older PLWH. An example is the National Older Adults with HIV (NOAH) Initiative, which demonstrates how cross-sectoral collaboration can enhance the capacity of service providers to meet the needs of older PLWH, advocating for policy changes and improved access to services [28].
• Advocacy and Patient Voice: Policies should support and amplify the voices of older PLWH and their advocates. Patient advocacy groups play a vital role in raising awareness, informing policy development, and ensuring that care models are truly patient-centered and address lived experiences. Policy frameworks should support the formation and sustainability of such groups.

4.2. Community-Based Interventions

Engaging communities in the development and delivery of HIV care services is crucial for enhancing accessibility, acceptability, and cultural relevance. Community-based interventions can bridge gaps between clinical care and daily living realities:

• Decentralized Service Delivery: Moving beyond traditional hospital or clinic settings, community-based programs can deliver care in more accessible locations such as senior centers, community health centers, or even through mobile clinics. This approach can overcome transportation barriers and reduce the perceived ‘medicalization’ of care [29].
• Community Health Workers (CHWs) and Peer Navigators: These vital frontline workers, often from the same community as the patients, can provide culturally sensitive outreach, health education, linkage to care, and practical support in navigating complex systems. Peer navigators, in particular, leveraging their lived experience with HIV, can build trust and facilitate engagement among older PLWH.
• Age-Friendly HIV Clinics: Designing physical clinic spaces and service delivery models to be explicitly ‘age-friendly’ can significantly improve the experience for older PLWH. This includes comfortable seating, clear signage, accessible restrooms, reduced wait times, and staff trained in geriatric principles and communication strategies. Creating welcoming and non-stigmatizing environments is paramount.
• Partnerships with Existing Community Organizations: Collaborating with established senior centers, LGBTQ+ community centers, faith-based organizations, and organizations serving specific racial/ethnic groups can facilitate the delivery of health information, support groups, and social activities tailored to the unique needs and cultural contexts of various older PLWH populations.
• Social Support Programs: Developing and scaling up community-based programs focused on reducing social isolation, such as peer support groups for older PLWH, intergenerational mentorship programs, and structured social activities, can foster a sense of belonging and improve mental and physical health outcomes.

These community-based strategies emphasize accessibility, cultural responsiveness, and holistic support, recognizing that health is profoundly shaped by social environments and connections.

4.3. Technological Innovations

Leveraging technological advancements offers transformative potential to improve care coordination, enhance patient engagement, and overcome logistical barriers for older PLWH:

• Telehealth and Telemedicine: The expansion of telehealth services (video consultations, remote monitoring) can significantly benefit older PLWH, particularly those with mobility issues or living in rural areas. Telemedicine can facilitate access to specialists (e.g., geriatricians, mental health professionals) who may not be locally available, enable remote medication management, and provide virtual support groups. Challenges such as the digital divide and ensuring privacy must be addressed through targeted training and infrastructure development.
• Electronic Health Records (EHRs) and Interoperability: Robust, interoperable EHR systems are critical for integrated care. They allow all members of the multidisciplinary team to access comprehensive patient information, including medications, comorbidities, lab results, and care plans. EHRs can also incorporate decision support tools for polypharmacy management, geriatric screening prompts, and alerts for potential drug-drug interactions, significantly improving patient safety and care coordination [30].
• Remote Monitoring Devices: Wearable technologies and smart home devices can offer remote monitoring of vital signs, activity levels, sleep patterns, and even detect falls. This passive monitoring can provide valuable data for proactive interventions, enhance safety, and allow older adults to ‘age in place’ with greater confidence, reducing the need for frequent in-person visits.
• Digital Health Interventions: Developing and evaluating digital interventions (e.g., mobile apps, online platforms) for specific needs, such as medication reminders, cognitive training, mental health support (e.g., online therapy platforms), and health education, can empower older PLWH in self-management and improve adherence. These tools must be user-friendly and accessible to individuals with varying levels of digital literacy.
• Patient Portals and Communication Platforms: Secure online patient portals allow individuals to schedule appointments, access lab results, communicate with their care team, and request prescription refills. These platforms can enhance patient engagement and communication, reducing the burden of phone calls and facilitating timely information exchange.

While technology offers immense promise, its implementation must be accompanied by strategies to address equitable access, digital literacy, and data security, ensuring that no older PLWH is left behind.

4.4. Research and Data Collection

Continued, focused research and robust data collection are essential to build an evidence base for optimizing geriatric HIV care. Much remains unknown about the long-term effects of HIV and ART on aging, and how best to intervene to promote healthy aging in this population:

• Longitudinal Cohort Studies: Establishing and maintaining large-scale, long-term longitudinal cohort studies specifically focusing on older PLWH is crucial. These studies can track the incidence and progression of age-related comorbidities, the impact of different ART regimens on accelerated aging, changes in functional status, and the long-term effects of chronic inflammation and immune activation [31]. Such data can inform preventive strategies and tailored interventions.
• Implementation Science Research: There is a critical need for research on how to effectively implement integrated geriatric HIV care models in diverse settings (e.g., rural vs. urban, high-income vs. low-income countries). This includes studies on feasibility, cost-effectiveness, scalability, and patient acceptability of different care models (e.g., co-located clinics, telehealth integration, multidisciplinary team approaches). Understanding implementation barriers and facilitators is key to translating evidence into practice.
• Pharmacogenomics and Pharmacokinetics in Older PLWH: Research into how age-related physiological changes affect drug metabolism and distribution in older PLWH is vital. This includes investigating potential genetic variations that influence drug responses or toxicities, leading to more personalized and safer medication prescribing.
• Biomarkers of Accelerated Aging: Identifying reliable biomarkers for accelerated aging, chronic inflammation, frailty, and organ damage in PLWH can enable earlier detection of risk and intervention strategies to prevent or mitigate adverse outcomes. This research can bridge the gap between biological aging and chronological age in this population.
• Patient-Reported Outcomes (PROs): Shifting the focus beyond clinical markers to include patient-reported outcomes such as quality of life, functional status, symptom burden, and satisfaction with care is paramount. PROs provide a critical patient perspective on the impact of HIV and aging, informing person-centered care and policy decisions.
• Data Linkage and Registry Integration: Encouraging data linkage between HIV registries, geriatric health databases, and national health surveys can provide a more comprehensive picture of the health and social needs of older PLWH, allowing for more precise epidemiological studies and policy evaluation.

Investing in this targeted research will generate the necessary evidence to refine current practices, develop innovative solutions, and ultimately improve the health span and quality of life for older PLWH.

4.5. Education and Training

Addressing the healthcare workforce limitations requires a robust and sustained investment in education and training across all levels of healthcare provision. This will ensure that current and future providers are equipped with the specialized knowledge and skills to care for older PLWH:

• Interdisciplinary Training Programs: Developing and expanding joint training programs for infectious disease fellows and geriatric fellows would be transformative. These programs would provide trainees with comprehensive exposure to both HIV-specific complexities and the nuances of geriatric care, fostering a new generation of providers with dual expertise. Similarly, integrated curricula for nursing, pharmacy, and social work students are essential.
• Continuing Medical Education (CME) and Professional Development: Mandating and developing high-quality CME modules focused specifically on geriatric HIV for all relevant healthcare professionals (primary care physicians, nurses, pharmacists, mental health providers) is critical. These programs should cover topics such as comprehensive geriatric assessment, polypharmacy management in HIV, cognitive and mental health issues in older PLWH, and addressing stigma.
• Curriculum Integration: Integrating core principles of geriatric HIV into standard medical school, nursing, pharmacy, and allied health curricula is essential. This ensures that even general practitioners and specialists have foundational knowledge of the unique needs of older PLWH.
• Mentorship and Peer Learning: Establishing mentorship programs where experienced clinicians in either HIV or geriatrics can guide and train those seeking to develop dual expertise can accelerate knowledge transfer and skill development. Peer-to-peer learning networks and communities of practice can also facilitate ongoing professional development.
• Team-Based Learning and Simulations: Implementing team-based learning exercises and simulation scenarios that mimic the complex clinical presentations of older PLWH can enhance interprofessional collaboration and problem-solving skills, preparing entire care teams to work cohesively.
• Addressing Stigma and Promoting Cultural Humility in Training: Education must also focus on fostering cultural humility, empathy, and sensitivity among healthcare providers. Training programs should explicitly address HIV-related stigma, ageism, and discrimination against LGBTQ+ individuals, ensuring that providers offer compassionate, non-judgmental, and respectful care.

By systematically investing in education and training, healthcare systems can cultivate a workforce capable of providing the comprehensive, integrated, and patient-centered care that older PLWH so urgently need.
