Doctor pharmaceutical utilization behaviour changed by the global budget programme strategies on hypertensive outpatient prescription.

RATIONALE, AIMS AND OBJECTIVES: This study was to examine changes in doctor pharmaceutical utilization behaviour in response to Taiwan's newly implemented National Health Insurance individual hospital global budget (GB) programme and the changes in health care costs and prescription trends for hypertensive (HT) patients.

METHOD

We analysed hospital outpatient prescription utilization with a pre-post individual hospital GB group and comparison group (the hospitals who did not join the programme) to evaluate the impact of GB strategies on hypertensive expenditure. Descriptive analyses were performed based on the average daily medication expenditure for each prescription, and average number of items per prescription.

RESULTS

This study reviewed 16,770,057 outpatient records and prescription records of 213,568 hypertensive patients. The average total medication expense (+17.6%), HT medication expense (+8.8%), daily medication expense (+16.3%), and daily HT medication expense (+6.3%) significantly increased after the action. After the individual hospital GB action, hospital doctors participating in action switched their patients' prescription drugs to other less expensive drugs such as rennin-angiotensin-aldosterone system inhibitors (-1.1%). The increase in volume of medications prescribed for control group were significantly larger for both alfa- and beta-adrenergic blocking agents (1.5%), and calcium channel blocking agents (3.9%).

CONCLUSION

The individual hospital GB programme slowed down the trend of prescription drug cost increasing rate and reduced the prescription drug volume in hospitals.
