Effect of rebate regulation on prescribing antihypertensive drugs in korea
During the analyzed period the major changes of rebate regulation were inspected and categorized by target, intensity, and whether there was disciplinary action or not. For specific analysis 60 months of analyzed period were set by major interventions. Using interrupted time series analysis and segmented regression analysis, the change of prescribing patterns which include prescription rate, cost, and number of days of prescribing antihypertensive drugs. The claim data of patients who was prescribed first time were analyzed because of possibility of restricted choice in second or multiple visit patients.
On descriptive analysis, the prescription rate of clinic was the highest and prescription of antihypertensive drugs was almost 28% and was different with hospital's and clinic's. Daily antihypertensive drug cost was estimated approximately 470KRW in territory hospitals and general hospitals and decreasing trend was inspected at 2011 because of decrease of antihypertensive drug price. On the result of analysis with first visit patients claim data, daily antihypertensive drug cost was also decreased during the study period and result of clinic was the lowest. Number of prescribing days of antihypertensive drugs per claim was continuously increased during the study period but with data of first visit patient was comparably stable during the study period. This result reflect the trend that doctors consider the compliance of drugs on prescribing to first visit patient.
On this study, could find the need of tighten the rebate regulation because there's a possibility that the doctors, pharmaceutical companies, and hospitals recognize the different rebate regulation as formal and also find the need of stratification of rebate regulation policy because of the different effect size of rebate regulation by hospital levels.
