Data management
A child contact management record will be implemented and maintained by healthcare workers. The child contact management record will be maintained at the health facility in both the intervention and control clinics. Additionally, in Ethiopia, health extension workers will maintain a record in the community at the health post (intervention arm only). These data will be synced with the clinic file monthly. Data will be extracted retrospectively from these routine clinic charts either onto clinical research forms (Ethiopia) or directly into a REDCap database (South Africa), no less than one month after the clinic visit to allow sufficient time for charting.Data will be entered and maintained on a secure, password-protected, web-based REDCap database with multisite access with secure web authentication and secure sockets layer encryption. The data constitutes a limited data set and does not include identifiers like name, date of birth, address or phone number, medical record number, and identity number.This small, unmasked study presents minimal risk to study participants and therefore does not meet criteria for a data safety and monitoring board.
