Motivation: Cancer has become the most significant cause of death in Taiwan since 1982. To view the top-ten list of cancer, female breast cancer, possesses the highest incidence rate, as well as the fourth highest mortality rate, which is merely lower than lung cancer, hepatic cancer and colorectal cancer. “NHI Breast Cancer Pay-for-performance Enhancement Program” has been one of the schemes raised by national government in order to prevent or cure breast cancer. Database from National Health Insurance (NHI) would be applied on the investigation of the program efficiency. Methodology: The patients with the first incidence of breast cancer (290 patients) from Registry for catastrophic illness patients (HV) would be selected by the one million insured under Longitudinal Health Insurance Database. And then the Outpatient care expenditures by visits (CD) and Inpatient expenditures by admissions (DD) would be combined hence two categories, which are outpatient care accepted (290 patients) and hospital admission (281 patients) respectively, are classified. Five-year panel data since 2011 has targeted on the patients who have the first incidence of breast cancer and accept the Breast Cancer Pay-for-performance Pilot Program (69 patients), as well as those without Pilot Program (218 patients). Statistical tests on age, frequency of outpatient care, outpatient care expenditures, frequency of admission, length of stays and admission expenditures would be applied to observe the significance. Also, linear regression would be operated based on years and the participation of Pay-for-performance program. Empirical Result: For the patients with the first incidence of breast cancer, either joining in program or not, looks insignificant to age, frequency of outpatient care and outpatient care expenditures, yet the frequency of admission, length of stays and admission expenditures which indicate the adequate significance. For those who participated in the program, the decline of outpatient care expenditures, frequency of admission, length of stays and admission expenditures under the ascending years accompanied cancer is quick than those who did not participate in the program. To consider the survival rates and cumulative survival rates, the patients with pay-for-performance program have the higher survival rates within first two years and have the higher cumulative survival rates within first three years. In the contrary, the survival rates in the third to the fifth year of suffering from cancer, as well as the cumulative survival rates in the fourth to the fifth year of suffering from cancer become lower if the patients participate in the pay-for-performance program. Conclusion: Efficiency of utilization on hospital admission can be boosted by program participation whereas there is indifference for outpatient care without program participation. That would provide a direction for government to improve the pilot program.
