Systematic review on the use of patient-held health records in low-income and middle-income countries

Objective To review the available evidence on the benefit of patient-held health records (PHRs), other than maternal and child health records, for improving the availability of medical information for handover communication between healthcare providers (HCPs) and/or between HCPs and patients in low-income and middle-income countries (LMICs). Methods The literature searches were conducted in PubMed, EMBASE, CINAHL databases for manuscripts without any restrictions on dates/language. Additionally, articles were located through citation checking using previous systematic reviews and a grey literature search by contacting experts, searching of the WHO website and Google Scholar. Results Six observational studies in four LMICs met the inclusion criteria. However, no studies reported on health outcomes after using PHRs. Studies in the review reported patients' experience of carrying the records to HCPs (n=3), quality of information available to HCPs (n=1) and the utility of these records to patients (n=6) and HCPs (n=4). Most patients carry PHRs to healthcare visits. One study assessed the completeness of clinical handover information and found that only 41% (161/395) of PHRs were complete with respect to key information on diagnosis, treatment and follow-up. No protocols or guidelines for HCPs were reported for use of PHRs. The HCPs perceived the use of PHRs improved medical information availability from other HCPs. From the patient perspective, PHRs functioned as documented source of information about their own condition. Conclusion Limited data on existing PHRs make their benefits for improving health outcomes in LMICs uncertain. This knowledge gap calls for research on understanding the dynamics and outcomes of PHR use by patients and HCPs and in health systems interventions. PROSPERO registration number CRD42019139365.
