Abstract
The purpose of the study was to analyze hypertension patients’ overlapped medical utilization by using the 2005 National Health Insurance Registry for Beneficiaries Claims Data files, the medical service utilization data of 200,000 persons. This study identified 20,209 hypertension patients visited western outpatient and emergency department. The percentage of overlapped medical resources utilization, overlapped medication and overlapped days of prescriptions was 39.83%, 41.62% and 2.75%, respectively. Among hypertension patients who used overlapped medical resources, 97.81% also had overlapped medication. The average overlapped days of prescriptions and overlapped medication expenses were 13.93 days and 508.46 points. Nineteen point six percent hypertension patients who used overlapped medical resources also had overlapped non-drug orders. The average overlapped non-drug orders expenses were 883.06 points. The average overlapped total orders expenses of 8,050 hypertension patients who used overlapped medical resources were 670.89 points and the overlapped total medical expenses were 3,331.19 points. Females were more likely to use overlapped medical resources, but the degree was lower than males. Hypertension patients’ medical demand and overlapped medical resources utilization increased as age increased. Once the patients used overlapped medical resources, subjects who did not need to pay copayments had higher degree of overlapped medical resources utilization than their counterpart. The probability and the degree of overlapped medical resources utilization were higher when the Charlson comorbidity index was higher. The more the number of doctors and medical facilities patients visited because of hypertension, the higher the probability and the degree of overlapped medical resources utilization. Subjects who did not have a regular place of care were less likely to overlap medical resources utilization than their counterparts and the degree of overlapped medical resources utilization was lower. onclusions: The majority of the hypertension patients who had overlapped medical resources utilization also had overlapped medication. Future researchers can incorporate questionnaire to investigate the reasons of overlapped medical resources utilization.
