[Between scientific management and research-action: the problem of overconsumption of drugs in Kasongo (Zaire)].

A Primary Health Care (PHC) system may be effective and efficient to the extent that essential drugs are available in health services and financially accessible to the population. In developing countries, besides the difficulties related to supplying health services with adequate amounts of drugs, the control of drug consumption is one of the frequent problems encountered by health authorities. Literature is relatively abundant in the field of rationalization of the diagnosis and drug prescription processes, and also in the field of drug financing mechanisms; publications are however rather scarce when topics related to corruption or drug misappropriation are concerned. The case study submitted hereafter reports a drug overconsumption problem in the health centres (HC) of the Kasongo district (Zaire). Despite the existence of direct control mechanisms as well as indirect ones (monitoring of drug consumption by HC), the problem has been identified belatedly. The district staff then used a step-by-step analysis of the HC drug consumption profiles; this analysis allowed to demonstrate that misappropriation would be the most plausible hypothesis. In order to solve the misappropriation problem-the consequences of which jeopardized the functioning of the very health system-the district staff chose to involve the nurses, in charge of the HC, in the entire problem-solving process. This participative approach, involving different actors as partners, allowed to deepen the situation analysis and to elaborate solutions congruent with PHC principles and acceptable to all concerned.
