Implementation effect of cost control management of semaglutide injection based on interrupted time series analysis
Objective To evaluate the implementation effect of cost management of semaglutide injection.Methods The outpatient prescription information for semaglutide injection in Beijing Anzhen Hospital,Capital Medical University was col-lected from February 24 to September 27,2022.Interrupted time series analysis was used to evaluate the changes in cost per patient before and after the intervention of prescription management.Results By the implementation of special prescription management,the cost per patient was effectively reduced[pre-intervention(724.76±32.20)yuan vs.post-intervention(660.86±8.35)yuan].Using cost per patient as the dependent variable,the regression model of the interrupted time series equation was Y=732.99-0.83T1-68.33T2+1.77T3+ε.The cost per patient showed a slow downward trend of 0.83 yuan per week before the intervention(P>0.05),and the immediate effect of the intervention was a decrease of 68.33 yuan in cost per patient(P<0.05).After the intervention,the cost per patient showed a trend of increasing by 0.94 yuan per week(P>0.05)as the number of users gradually increased.Conclusion Prescription management can effectively reduce the cost per patient of semaglutide injection and control medication expenses reasonably.
