Physician concerns about medicine quality

By Roger Bate

The Safe Medicines Coalition is undertaking surveys of physicians in different cities in the world to ascertain knowledge and concern about inferior medicine quality. The first survey results from Africa are in and the summary statistics are below. 40 general physicians from the cities of Nairobi in Kenya, Lagos in Nigeria and Dar Es Salaam in Tanzania were surveyed. Some questions do not lend themselves to statistical compilation, so they are left blank in table 1 below. Over the next few months, we will release data from the surveys in both summary and more detailed form.

One of the more interesting findings is that local regulators are not trusted to provide quality medicines by the majority of physicians in each city. Trust was highest in Dar Es Salaam (35%), and lowest in Nairobi (15%). These results are not surprising given what we know about drug quality in these markets, and perhaps it is at least encouraging that physicians in these cities are aware of the shortcomings of the national agencies allegedly protecting them and their patients.

And their own patients’ experience with poor quality medicines is also important. Between 22.5% and 47.5% of physicians knew of instances where at least one of their patients was harmed by a medicine, but as is typical in the West, in only a very few instances, was the reason for the harm established. While harm could have been caused by factors other than medicine quality, many physicians thought quality a contributory factor.

*All figures are percentages answering yes to the primary question. Some questions do not lead to answers that can be compiled into summary statistics

Table 1. The above table is the summary statistics from the initial survey from three African cities, Nairobi, Kenya; Lagos, Nigeria; Dar Es Sallam, Tanzania. The detailed answers are still being compiled.
