Abstract: Pain is a common problem all over the world. A previous report estimated that the prevalence of pain is 40% in Japan. One of the roles of pharmacist is to build evidence with more patient-centered care, but less in region of pain. Our objective was to identify pharmacists’ contributions to patient care through pain-management using PainVision (PV) in an outpatient pain clinic and interventions with polypharmacy. We investigated 28 patients who underwent nerve blocks. Pain were assessed relatively and subjectively using PV and numerical analogue scale (NRS), respectively. The pharmacist intervened pre- and post-nerve block. Interventions focused on evaluations of pain, drug efficacy, complications, blood pressure, pulse rate, and oxygen saturation. Wilcoxon signed-rank test, Spearman rank correlation coefficient and Friedman test were used to analyze the data. The mean age of the patients was 77 (interquartile range 69-84) years, and 12 patients were diagnosed with zoster-associated pain. The pharmacists consulted with patients 213 times and evaluated pain 426 times. We found that the analgesic effect of nerve block were evaluated PV (70; 23-162→20; 5.0-49) and NRS (4; 2-6→1; 0-2) by pharmacist, significantly. It was significant correlation between PV and NRS (r=0.799: P<0.001). Our study showed similar results to previous studies in which doctors and nurses used PV. It is clinically valuable for pharmacists to using PV in outpatient clinics to evaluate pain. Greater roles for pharmacists in hospital outpatient department should be considered, especially pharmacist-led clinical research.
