Government inspection and peer supervision visits
Government recommends monthly inspection visits by district drug inspectors. However, results in table 3 revealed that inspection was not done as per statutory recommendations. The slight but insignificant increase in number of inspection visits by the district drug inspector in the intervention district were in tandem with what has been referred to by many scholars as social proof34,35. In the social proof theory, people tend to do things because other people are doing them. This is in line with what the researchers of this study wanted to achieve-strengthening the district health system. Given that there was no statistical difference in inspection visits between DDIs from the two districts overall, we were able to attribute observable intervention effects to peer supervision.
