The results show an average adherence of 98.5%, which is very good indeed. Expected adherence, however, would have been 100%. This performance could have been due to inclusion of the Essential drug concept in training/curriculum, policy emphasis and indeed streamlining and making available the key (essential) drugs in all health facilities. This situation is a positive contribution of the National Essential Drugs program. The shortfall of 1.5% could be due to special requested drugs for certain medical cases which are not in NEDLIT.
