The roles, responsibilities and perceptions of community health workers and ward-based primary health care outreach teams: a scoping review

Abstract

Background: Community health workers play important roles in rural primary health care settings. They work within ward-based primary health care outreach teams yet their roles are not always clearly defined and operationalized. There is thus a need to explore perceptions about the roles and responsibilities of community health workers. Objective: To investigate the roles, responsibilities and effectiveness of community health workers working within ward-based primary health care outreach teams. Method: A scoping review of the published peer reviewed literature on community health workers working in ward-based primary health care outreach teams within low and middle-income countries was conducted. The following five electronic databases were searched: EBSCOhost, Google Scholar, Science Direct, EMBASE, PubMed, and Clinical key. Out of 69,969 identified articles, 31 met the inclusion criteria. The majority of the studies were from South Africa. Results: Both positive and negative perceptions were reported. Suggestions for improvements were also put forward. Positive factors included: ongoing training and up skilling; collaboration and trust building with other health care workers; mentoring and supervision; motivation and recognition, and incentives and remuneration. Negative factors covered: inadequate mentorship and poor supervision; role conflict; lack of support; poor remuneration; inadequate manpower; poor knowledge, and insufficient training. The review identified the following as the roles and responsibilities of community health workers: conducting home visits; identifying vulnerable community groups; promoting health and wellness; increasing access to health care; contact tracing; delivering health education; giving counselling and psychosocial support, and providing preventive health services. Conclusion: The information available for community health workers in terms of their roles, responsibilities and effectiveness is inadequate, considering their roles and responsibilities in ward-based primary health care outreach teams. This lack of information constitutes barriers to effective service delivery, a common situation among this group of community health workers.
