The Impact of Health Workers' Strikes on Health Outcomes and Health Service Utilization in Low-and Middle-Income Countries: A Systematic Review

Abstract

Background The impact of strikes by health workers in low- and middle-income countries (LMIC) is not well described. We systematically reviewed articles on the impact of health workers’ strikes on health outcomes or health service utilization in LMIC. Methods We searched PubMed, SCOPUS, Web of Science, and Google Scholar databases on May 27, 2019. To be included for review, articles met the following criteria: (1) reported on a strike that involved at least one cadre of health worker; (2) reported on a strike in a LMIC; (3) included at least one outcome related to patient or population health or health service utilization; and, (4) included a reference group or time period. There were no date or language restrictions. We modified the Newcastle-Ottawa Tool to appraise study quality. The review is registered with PROSPERO (CRD42019124989). Findings Among 5,123 articles, eleven articles met inclusion criteria. Studies examined 20 strikes in LMIC from 1991 to 2017 (average strike length of 32·9 days), with five studies from Kenya, two each from India and Nigeria, and one each from Malawi and South Africa. The majority of studies reported hospital admissions or inpatient mortality. Generally, health service utilization decreased during strike periods, but changes in patient mortality and other health outcomes varied. Study quality was heterogenous with most studies reporting from a single facility or medical department. Interpretation Compared to high-income settings, our study suggests a more complex picture of the effect of strikes by health workers on health and health service utilization outcomes in LMIC.
