Abstract
Using hospital database managed by Japan Hospital Pharmacist Association, 58 hospitals were randomly selected and 271 case data of inpatients who received medication counseling and instruction by hospital pharmacists were collected. Pharmacists with “check sheet ” evaluated these inpatients about understanding of medication, anxiety for medication, and compliance with medication instruction twice, just after admission and just before discharge. Using collected data, Wilcoxon matched-pair signed-rank test was performed to clarify the effects on patient outcomes by performing medication counseling and instruction. The results were as follows: (1) patient understanding of medication was significantly improved. (2) patient anxiety for medication was significantly relieved. (3) patient compliance with medication instruction was significantly improved. As the reason of the study results, there are facts that the patient outcomes about medication were significantly improved by pharmacists' performance of medication counseling and instruction in hospitals.
