Documenting capacity and existing gaps in reporting adverse events following immunisation in Northern Ghana: a quantitative cross-sectional survey of healthcare workers.
Article in BMJ public health, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: Immunisation remains an indispensable tool in preventing infectious diseases. A robust pharmacovigilance system assures the public of vaccine safety, particularly in countries like Ghana where there is relatively low reporting of adverse events following immunisation (AEFIs). We explored the experiences of health workers in Ghana to ascertain the existing capacity for data collection and information reporting flows for health events associated with vaccination in the country. Methods: We conducted a cross-sectional quantitative survey among healthcare workers (HCWs) in Ghana between December 2020 and April 2021. We documented their experiences with regard to knowledge, perceptions and practice of reporting AEFIs to the national pharmacovigilance centre (Ghana Food and Drugs Authority). Results: Out of 851 participants, 49.2% said their institutions had processes for AEFI reporting. Additionally, 25% of participants had encountered an AEFI within the past year. Out of this number, 55% reported the AEFI. Only 31.2% of community health nurses (vaccinators) considered AEFI reporting part of their job description. Most HCWs (59.34%) had fair to poor knowledge of AEFIs. The main factors affecting AEFI reporting were heavy workload and lack of time (54.1%) and unavailability of reporting forms (57.5%). Only 2% of participants were aware AEFIs could be reported online. Logistic regression analysis revealed female gender as a negative factor influencing AEFI reporting. Training (p<0.0001) and profession (p=0.006) significantly influenced knowledge level of AEFIs. Results of the multiple binary logistic regression indicate that the age and profession of HCWs are the main factors influencing knowledge of reporting AEFIs. Conclusion: The vaccine pharmacovigilance system in Ghana can be strengthened with targeted regular training on AEFI reporting, guidelines for reporting in all health facilities and prompt feedback from the national pharmacovigilance centre to health workers.
