Impact of pre-packaging antimalarial drugs and counselling on compliance with malaria treatment at Port Moresby General Hospital Adult Outpatient Department

Abstract

We investigated the impact of pre-packaging antimalarial drugs and counselling on compliance with treatment of malaria at the Adult Outpatient Department of Port Moresby General Hospital. Adult patients who were prescribed standard antimalarial drugs following clinical and microscopic diagnosis of malaria were randomly assigned to one of three groups: an intervention group, where pre-packaging and counselling instructions were applied; control group A, with counselling but no pre-packaging; and control group B, with neither counselling nor pre-packaging. Patients were interviewed on two occasions, day 1 of treatment and day 4 post treatment. Of a total of 436 patients, 322 patients (179 males and 143 females) completed the study. Our data indicate an increase of 18% in compliance with treatment in the intervention group and 16% in control group A, when compared with control group B. While compliance with treatment was gender independent, the language spoken and used for giving instructions and counselling may have influenced patients' behaviour on prescribed medication. The results of our study indicate that a simple pre-packaging system and proper counselling could improve compliance with antimalarial drug treatment. As an additional beneficial observation, pre-packaging is likely to eliminate errors and possible contamination of the products during dispensing.
