Improving the use of pharmaceuticals through patient and community level interventions

Abstract

Pharmaceuticals represent an increasing share of private and public health care expenditures. However, while most governments are interested in ensuring availability and access to drugs, the issue of adequate use of drugs remains a low priority in most third world countries. This paper summarizes the results of interventions conducted in developing countries aimed at improving patients’ compliance with the advice of health professionals and/or to decrease the unnecessary use of drugs by the general population. Forty-five studies were identified through literature searches and networking; and only about a third of them fulfilled the eligibility criteria for inclusion in the review. Given the paucity of information available and the importance of the topic the authors report on all 45 studies identified. Although much remains to be explored there are several interventions that deserve to be highlighted. The authors argue that improving the use of pharmaceuticals through interventions directed only to consumers may have a small impact and suggest that in order to obtain meaningful changes it might be necessary to design interventions to modify the behavior of all the actors in the medication cycle (manufacturers, health professionals, retailers, consumers and governments). They suggest that the extraordinary therapeutic effects of antibiotics, coupled with the problems that may arise when they are inappropriately used and with the extraordinary amount of resources spent on antibiotics worldwide justify a global effort to reduce their inappropriate use and promote their adequate administration. The complexity of this type of intervention would require the support of the pharmaceutical industry, governments, private foundations, and international organizations.
