Feasibility and acceptability of training community health workers in ear and hearing care in Malawi: a cluster randomised controlled trial

Abstract

ObjectiveTo assess the feasibility and acceptability of training community health workers (CHWs) in ear and hearing care, and their ability to identify patients with ear and hearing disorders.DesignCluster randomised controlled trial (RCT).SettingHealth centres in Thyolo district, Malawi.ParticipantsTen health centres participated, 5 intervention (29 CHWs) and 5 control (28 CHWs).InterventionIntervention CHWs received 3 days of training in primary ear and hearing care, while among control CHWs, training was delayed for 6 months. Both groups were given a pretest that assessed knowledge about ear and hearing care, only the intervention group was given the posttest on the third day of training. The intervention group was given 1 month to identify patients with ear and hearing disorders in their communities, and these people were screened for hearing disorders by ear, nose and throat clinical specialists.Outcome measuresPrimary outcome measure was improvement in knowledge of ear and hearing care among CHWs after the training. Secondary outcome measures were number of patients with ear or hearing disorders identified by CHWs and number recorded at health centres during routine activities, and the perceived feasibility and acceptability of the intervention.ResultsThe average overall correct answers increased from 55% to 68% (95% CI 65 to 71) in the intervention group (pConclusionsTraining was effective in improving the knowledge of CHW in ear and hearing care in Malawi and allowing them to identify patients with ear and hearing disorders. This intervention could be scaled up to other CHWs in low-income and middle-income countries.Trial registration numberPan African Clinical Trial Registry (201705002285194); Results.
