ABSTRACT
Background During the COVID-19 pandemic, access to health care for people living with non-communicable diseases (NCDs) has been significantly disrupt-ed. Calls have been made to adapt health systems and innovate service delivery models to improve access to care. We identified and summarized the health sys-tems adaptions and interventions implemented to improve NCD care and their potential impact on low-and middle-income countries (LMICs). Methods We comprehensively searched Medline/PubMed, Embase, CINAHL, Global Health, PsycINFO, Global Literature on coronavirus disease, and Web of Science for relevant literature published between January 2020 and Decem-ber 2021. While we targeted articles written in English, we also included papers published in French with s written in English.Results After screening 1313 records, we included 14 papers from six countries. We identified four unique health systems adaptations/interventions for restoring, maintaining, and ensuring continuity of care for people living with NCDs: tele-medicine or teleconsultation strategies, NCD medicine drop-off points, decen-tralization of hypertension follow-up services and provision of free medication to peripheral health centers, and diabetic retinopathy screening with a handheld smartphone-based retinal camera. We found that the adaptations/interventions enhanced continuity of NCD care during the pandemic and helped bring health care closer to patients using technology and easing access to medicines and rou-tine visits. Telephonic aftercare services appear to have saved a significant amount of patients' time and funds. Hypertensive patients recorded better blood pressure controls over the follow-up period.Conclusions Although the identified measures and interventions for adapting health systems resulted in potential improvements in access to NCD care and better clinical outcomes, further exploration is needed to establish the feasibility of these adaptations/interventions in different settings given the importance of context in their successful implementation. Insights from such implementation studies are critical for ongoing health systems strengthening efforts to mitigate the impact of COVID-19 and future global health security threats for people liv-ing with NCDs.
