Objective To explore intervention the effect of family pharmacist and medication management on medication compliance and unreasonable drug use in contracted patients. Methods A total of 100 patients with chronic diseases from March 2017 to March 2021 in our hospital were selected as prospective study subjects. According to the random remainder method,they were divided into control group and research group with 50 cases in each group. Among them,the control group was surveyed in the first followed-up,and the health information of patients was collected to establish drug use files,and evaluation was performed in the final follow-up. Family pharmacists and family physicians intervened together or directly to formulate specific solutions to help patients achieve the treatment goals and explain the treatment goals. The changes of medication compliance,quality of life and drug use before and after intervention were compared between the two groups. Results Before the intervention,the medication compliance scores of the two groups were not significantly different (P>0.05).After the intervention,the medication compliance scores of the two groups improved with time,while the medication compliance scores of the research group were significantly higher than the control group,statistics analysis showed that the difference was significant (P<0.05).The reasonable selection,the reasonable frequency,the reasonable titration,the reasonable drug change,and the reasonable combined medication in research group were significantly more than the control group,and the differences were statistically significant (P<0.05).Conclusions Family pharmacist and medication management intervention could effectively improve medication compliance and quality of life of patients,improve drug use,had a certain reference value for chronic disease patients.
