1. Introduction

The global population is aging rapidly, with a significant increase in the number of older adults experiencing multiple chronic conditions, functional decline, and cognitive impairment. This demographic shift presents significant challenges to healthcare systems worldwide, necessitating a paradigm shift towards more comprehensive and integrated approaches to geriatric care. Geriatric medicine, a specialized field focused on the unique healthcare needs of older adults, plays a crucial role in addressing these challenges by providing comprehensive assessments, developing individualized care plans, and coordinating multidisciplinary interventions.

Effective referral pathways to geriatric medicine teams are essential for ensuring that older adults receive timely and appropriate care. These pathways facilitate access to specialized geriatric expertise, which can lead to improved health outcomes, reduced hospital readmissions, and enhanced quality of life. However, referral patterns are often inconsistent and influenced by a complex interplay of factors, including physician awareness of geriatric services, perceived barriers to referral, patient characteristics, and organizational factors. Consequently, many older adults who could benefit from geriatric consultations do not receive them, leading to suboptimal care and increased healthcare costs.

This research report aims to provide a comprehensive overview of referral pathways to inpatient geriatric medicine, with a particular focus on addressing disparities in access to care. The report will examine the key determinants of referral decisions, identify potential barriers to referral, and explore strategies for improving referral processes and ensuring that all eligible older adults receive timely geriatric consultations. Furthermore, the report will address the specific challenges associated with referring older adults with cancer to geriatric medicine teams, considering the potential for negative interactions between cancer and geriatric treatments.

2. Determinants of Referral to Geriatric Medicine

Referral decisions are influenced by a multitude of factors operating at different levels, including patient characteristics, physician perceptions, organizational context, and system-level policies. Understanding these determinants is crucial for identifying targets for intervention and improving referral pathways.

2.1 Patient Characteristics

Patient-related factors play a significant role in referral decisions. Older adults with multiple chronic conditions, functional decline, cognitive impairment, falls, and polypharmacy are more likely to be referred to geriatric medicine teams. However, even among individuals with these characteristics, referral rates can vary significantly. Age itself is a weak predictor, highlighting the importance of considering frailty and functional status rather than chronological age alone. Furthermore, socioeconomic status, ethnicity, and geographic location can also influence referral patterns, with disparities observed in access to geriatric services among underserved populations. Notably, older adults with cancer, particularly those undergoing active treatment, are often under-referred to geriatric medicine teams, potentially due to concerns about the complexity of managing both oncological and geriatric issues.

2.2 Physician Perceptions and Knowledge

Physician knowledge and perceptions of geriatric medicine services are critical determinants of referral decisions. Physicians who are knowledgeable about the benefits of geriatric care and have positive attitudes towards geriatric medicine are more likely to refer patients. However, many physicians lack awareness of the full range of geriatric services available or have misconceptions about the scope of geriatric practice. Perceived barriers to referral, such as time constraints, lack of access to geriatric specialists, and concerns about disrupting the patient’s relationship with their primary care physician, can also deter referrals. In the context of older adults with cancer, oncologists may prioritize cancer-specific treatments and be less aware of the potential benefits of geriatric assessment and management in optimizing overall health and functional status. A lack of awareness of the potential negative interactions between cancer and geriatric treatments may also contribute to lower referral rates.

2.3 Organizational Factors

Organizational factors, such as the availability of geriatric services, the structure of referral pathways, and the presence of interdisciplinary teams, can significantly impact referral patterns. Hospitals with dedicated geriatric units, geriatric consultation services, and formalized referral protocols are more likely to have higher referral rates. The integration of geriatric medicine into primary care settings and other specialty areas can also facilitate referrals. However, many healthcare systems lack adequate geriatric resources, leading to limited access to care. Furthermore, complex referral pathways, lack of communication between providers, and inadequate reimbursement policies can create barriers to referral. The organizational culture and leadership support for geriatric medicine are also important determinants of referral success. For example, if a cancer centre is predominantly focused on cutting edge treatments and there is a perception that the treatment plan will be adversely affected by geriatric input then fewer referrals are likely.

2.4 System-Level Policies

System-level policies, such as payment models, quality metrics, and regulatory requirements, can also influence referral patterns. Fee-for-service payment models may incentivize volume-based care and discourage referrals to geriatric medicine, which often involves comprehensive assessments and time-intensive interventions. Quality metrics that focus on specific disease outcomes may not adequately capture the benefits of geriatric care, which often aims to improve functional status, quality of life, and reduce hospital readmissions. Regulatory requirements, such as those related to hospital accreditation and long-term care, can promote the integration of geriatric principles into clinical practice. However, the impact of these policies on referral patterns can be complex and multifaceted. Changes in health policy that directly incentivize proactive referrals for geriatric assessment in the context of cancer treatment would likely have a positive effect.

3. Barriers to Referral

Several barriers can impede the referral of older adults to geriatric medicine teams. Addressing these barriers is essential for improving access to care and ensuring that all eligible individuals receive timely geriatric consultations.

3.1 Lack of Awareness and Understanding

A significant barrier to referral is the lack of awareness and understanding of geriatric medicine services among healthcare providers and patients. Many physicians are not fully aware of the scope of geriatric practice or the potential benefits of geriatric assessment and management. Patients may also be unfamiliar with geriatric medicine and hesitant to seek specialized geriatric care. Furthermore, cultural beliefs and attitudes towards aging can influence referral decisions, with some individuals viewing aging as a natural process that does not require medical intervention. Targeted educational initiatives are needed to increase awareness of geriatric medicine and promote the value of geriatric consultations.

3.2 Perceived Complexity and Time Constraints

Referring older adults with complex health needs can be perceived as time-consuming and challenging. Physicians may feel that they lack the time or expertise to adequately assess and manage the multiple chronic conditions, functional decline, and cognitive impairment that are common in older adults. Furthermore, the complexity of geriatric care can require extensive communication and coordination among multiple providers, which can be challenging in busy clinical settings. Streamlining referral processes and providing readily accessible resources and support can help alleviate these perceived barriers. Developing standardized referral forms, utilizing electronic health records to facilitate communication, and offering telephone consultations with geriatric specialists can improve the efficiency of referral processes.

3.3 Limited Access to Geriatric Services

Limited access to geriatric services is a major barrier to referral, particularly in rural and underserved areas. Many healthcare systems lack adequate geriatric resources, including geriatricians, geriatric nurses, and other geriatric specialists. Furthermore, the geographic distribution of geriatric services is often uneven, with limited availability in certain regions. Expanding the geriatric workforce and increasing access to geriatric services through telehealth and other innovative models of care are essential for addressing this barrier. Training programs for healthcare professionals in geriatric medicine are vital to increase the workforce. Incentives to work in rural or other undeserved areas can help to overcome geographical issues.

3.4 Fragmentation of Care

The fragmentation of care across different healthcare settings can create barriers to referral. Older adults often receive care from multiple providers, including primary care physicians, specialists, and hospitalists. Lack of communication and coordination among these providers can lead to duplication of services, conflicting treatment plans, and missed opportunities for referral to geriatric medicine. Improving communication and coordination among providers through integrated care models and shared electronic health records can help address this barrier. Case management services and interdisciplinary care teams can also play a crucial role in facilitating referrals and ensuring continuity of care.

3.5 Financial Constraints

Financial constraints can also impede referrals to geriatric medicine. Older adults with limited financial resources may be unable to afford the out-of-pocket costs associated with geriatric consultations or specialized geriatric services. Furthermore, reimbursement policies may not adequately compensate providers for the time and effort involved in providing comprehensive geriatric care. Advocating for policies that expand coverage for geriatric services and provide financial incentives for geriatric care can help reduce this barrier. Public funding initiatives and charitable organizations can play a key part in providing additional funding.

3.6 Concerns Regarding Interactions Between Cancer and Geriatric Treatments

There is a growing concern among Oncologists regarding the potential negative interaction between cancer and geriatric treatments. Cancer treatments such as chemotherapy and radiation therapy can have significant side effects in older adults, including fatigue, nausea, and cognitive impairment. Geriatric treatments, such as medication management and rehabilitation, can also have side effects that may interfere with cancer treatment. As a result, Oncologists may be reluctant to refer older adults with cancer to geriatric medicine teams due to the potential for increased complications. There is also a perceived increased risk of mortality with older adults with cancer on complex treatments which may be exacerbated by interventions for geriatric conditions. It is crucial to develop strategies for minimizing the potential negative interactions between cancer and geriatric treatments. This may involve conducting research to identify safe and effective geriatric interventions for older adults with cancer, as well as developing guidelines for managing the side effects of both cancer and geriatric treatments. Interdisciplinary collaboration between Oncologists and geriatricians is also essential to ensure that older adults with cancer receive coordinated and comprehensive care.
