A mixed-methods systematic review investigating the use of digital health interventions to provide palliative and end-of-life care for patients in low- and middle-income countries

Background: The need for palliative care is rising globally with 76% of those who are in need living in low- and middle-income countries (LMICs). Digital health interventions (DHIs) have been identified as a means of making palliative care more widely accessible. This review summarizes the range and characteristics of DHIs used to deliver palliative care in LMICs and sought to identify factors that influence their implementation and utilization. Objectives: This review aims to summarize the range and characteristics of DHIs used to deliver palliative care in LMICs and identify factors that influence their implementation and utilization. Design: Mixed-method systematic review incorporating both quantitative and qualitative data. Data sources and methods: All studies focusing on DHIs for patients who need palliative care (adults/children) and their caregivers (patient and caregiver centred) in LMICs and published in English were identified through a systematic search of MEDLINE, EMBASE, PsycINFO and CINAHL databases. Data synthesis and analysis were carried out following the convergent integrated approach based on the Joanna Briggs Institute (JBI) methodology for mixed-methods systematic reviews. Results: Fifteen studies were included (three qualitative, four mixed-methods and eight quantitative studies). Telemedicine/mHealth was the most reported DHI utilized in LMICs in delivering palliative care. Patients and caregivers benefited from using DHIs in many ways including increased access to care with reduced discomfort, travel time and risk of health care-associated infections. Health care providers also reported that using DHI such as telemedicine enables them to provide care in a more effective and efficient way. Four factors were identified as the main barriers to implementation: resource constraints; literacy, training and skills; governance, operational and communication issues and technical issues. Conclusion: DHIs, such as telemedicine, have the potential to enhance accessibility to palliative care in LMICs, particularly in rural areas. Comprehensive strategies for their use are required to address the identified barriers.
