Impact of Community Palliative Care Services on Palliative Care Utilization among Patients with Chronic Illnesses in Nigeria

Abstract

Palliative care is an important component of comprehensive healthcare for patients living with serious and chronic illnesses because it focuses on improving quality of life, relieving pain and other distressing symptoms, supporting psychosocial well-being, and addressing the needs of patients and their families. Patients with chronic illnesses in Nigeria may experience substantial physical, emotional, social, and financial challenges, while access to palliative care services may remain limited because of inadequate awareness, shortages of trained healthcare professionals, financial barriers, geographical inaccessibility, and weak referral systems. Community palliative care services provide an opportunity to bring supportive and symptom-management services closer to patients and families, particularly those who may experience difficulties accessing facility-based care. Against this background, this study investigates the impact of community palliative care services on palliative care utilization among patients with chronic illnesses in Nigeria. The study will be anchored on Andersen's Behavioral Model of Health Services Use, the Social Ecological Model, and the Chronic Care Model. Andersen's Behavioral Model explains healthcare utilization through predisposing characteristics, enabling resources, and perceived or evaluated healthcare needs. The Social Ecological Model emphasizes the influence of individual, family, community, healthcare-system, and broader environmental factors on access to and utilization of palliative care. The Chronic Care Model emphasizes coordinated care, patient self-management support, healthcare delivery systems, clinical information, and community resources in the management of chronic illnesses. Collectively, these theoretical perspectives provide a suitable framework for explaining how community palliative care services may influence palliative care utilization among patients with chronic illnesses in Nigeria. The study will adopt a quantitative quasi-experimental or analytical cross-sectional research design. The study population will comprise adults diagnosed with selected chronic or life-limiting illnesses and receiving care in selected communities, primary healthcare facilities, hospitals, or community-based palliative care programmes across Nigeria. A multistage sampling technique will be used to select geopolitical zones, states, local government areas, communities, healthcare facilities, and eligible patients. Community palliative care services will be assessed using indicators such as availability of community-based palliative care, home visits, symptom assessment and management, pain management, medication support, psychosocial counselling, caregiver education, advance care planning where appropriate, referral services, follow-up visits, community health worker involvement, availability of trained palliative care personnel, service frequency, accessibility, and programme coverage. Palliative care utilization will be assessed using indicators such as enrolment in palliative care programmes, frequency of palliative care visits, home-based care utilization, attendance at palliative care clinics, receipt of symptom-management services, medication utilization, psychosocial support utilization, caregiver support, referral completion, continuity of care, and duration of engagement with palliative care services. Data will be collected using structured questionnaires, validated palliative care utilization instruments, patient records, community palliative care registers, home-visit records, referral registers, and relevant programme documents, subject to appropriate ethical and confidentiality safeguards. Descriptive statistics will be used to summarize participants' characteristics, availability and accessibility of community palliative care services, and patterns of palliative care utilization. Inferential statistical techniques, including chi-square tests, t-tests, correlation analysis, and logistic or multiple regression analysis where appropriate, will be used to determine the impact of community palliative care services on palliative care utilization. Where a quasi-experimental design is adopted, utilization patterns before and after implementation of community palliative care services may be compared with those of a comparison group to determine changes associated with the programme. Diagnostic tests will also be conducted to assess the reliability, validity, and robustness of the findings. The study is expected to find that community palliative care services have a significant positive impact on palliative care utilization among patients with chronic illnesses in Nigeria. Patients who have access to community-based palliative care are expected to demonstrate greater utilization of symptom-management, pain-relief, psychosocial support, caregiver education, home-based care, and referral services than patients without access to such programmes. Bringing palliative care closer to patients' homes and communities may reduce geographical and financial barriers while improving continuity of care and reducing unnecessary travel to healthcare facilities. Community health workers, nurses, physicians, and other trained healthcare professionals may also facilitate earlier referral and ongoing monitoring of patients with complex care needs. However, inadequate funding, limited availability of essential medicines, shortage of trained palliative care professionals, low public awareness, cultural misconceptions, financial difficulties, weak referral networks, and limited integration of palliative care into primary healthcare may reduce programme effectiveness. The study therefore expects accessible, affordable, culturally appropriate, and well-coordinated community palliative care services to contribute significantly to improved utilization of palliative care among patients with chronic illnesses in Nigeria. The study is expected to contribute to the literature on community palliative care, palliative care utilization, chronic illness management, home-based healthcare, supportive care, quality of life, patient-centred care, primary healthcare, and public health in Nigeria. The findings will provide useful information to the Federal Ministry of Health and Social Welfare, National Primary Health Care Development Agency, state ministries of health, hospitals, primary healthcare facilities, palliative care organizations, community health workers, nurses, physicians, pharmacists, social workers, caregivers, development partners, and policymakers regarding strategies for expanding access to palliative care. The study will also provide evidence-based recommendations for integrating palliative care into primary healthcare and community health services, strengthening community-based referral and follow-up systems, improving access to essential palliative medicines and trained personnel, increasing public awareness, supporting caregivers, and developing sustainable community palliative care programmes across Nigeria.
