RESUMO
OBJECTIVES: In this study we aimed to evaluate the completeness of three different medication information sources that are commonly used to collect and obtain the Best Possible Medication History (BPMH). METHODS: This is an observational study which was held at Jordan University Hospital. After identifying eligible patients, the BPMH was obtained from three different sources separately. These sources include medical file, pharmacy database, and patients' interview. Information from all of these sources was compiled to create the BPMH. The BPMH was used as the standard against which every other information source was compared and given a "completeness score" according to a systematic scoring system. RESULTS: Among the 196 participating patients who were included in the study, 113 (57.7%) were recruited from internal medicine and 83 (42.3%) from surgical department. Patients' interview showed the highest median completeness score (71.4%) among the three used sources followed by pharmacy database (35.3%), and medical files (28.2%). The median completeness score for the compiled BPMH obtained by the pharmacist was 93.0%. The compiled BPMH completeness score was inversely proportional to the numbers of medications in the compiled BPMH (R = -.392, P value < .001). Moreover, patients with lower income showed better median BPMH completeness score compared with those with higher income (95.2% (IQR = 16.7%) vs 88.9% (IQR = 15.7%), respectively, P value = .042). CONCLUSION: The results show that pharmacist's interview with the patients scored the highest percentage of completeness compared with hospital pharmacy database and medical file and is, therefore, considered more comprehensive in obtaining the BPMH.
