Impact of a drug dispensing model at a Community Pharmacy in Goiânia, Goiás, Brazil
Although dispensing of medication has been addressed by theoretical models, studies that confirm the impact of this service are still needed. The objective was to evaluate the impact of a new model of medicine dispensing system on patients’ medication knowledge, adherence to treatment and satisfaction. One hundred and four patients attending the dispensing service of a community pharmacy between 21 January 2013 and 20 April 2013 were included in this intervention study. The impact of the service on patients’ medication knowledge, adherence to treatment and satisfaction was assessed by using validated questionnaires at two time points: at the moment of medication dispensing and 30 days thereafter by telephone contact. Statistical analysis was performed by McNemar’s test, and a p<0.05 was set as statistically significant. The number of patients showing insufficient knowledge about medications decreased by 50% (p < 0.05), and the number of those showing sufficient knowledge was three times greater (p < 0.05) after medicine dispensing. A high level of satisfaction was observed. Improvement of medication adherence, however, was not observed. The proposed system model for drug dispensing improved patients’ knowledge about medication and satisfaction.
