Overview

Cross-sectional observational study reveals high record completeness but variable reporting timelines for post-immunization adverse events, highlighting the value of active community surveillance.

Key Points

To evaluate the implementation of existing surveillance guidelines for adverse events following immunization (AEFI) and identify opportunities for reporting quality improvement.
Conducted a cross-sectional observational record-based evaluation in a metropolitan city in Maharashtra, India.
Extracted and analyzed case reporting forms (CRFs), preliminary case investigation forms (PCIFs), and final case investigation forms (FCIFs) for all AEFI cases from January 2017 to June 2018 (N=129).
CRFs were available for 100% of reported cases (129/129), PCIFs were completed for 91.5% (118/129), and FCIFs were updated for 84.5% of due cases (98/116).
Notification to the health system occurred within 24 hours in 17.83% of cases (n=23), between 24 and 48 hours in 26.36% (n=34), and between 48 and 72 hours in 24.03% (n=31).
