Medical utilization by liver cancer patients under the National Health Insurance program in Taiwan: A population-based cross-sectional study

Aims: Taiwan implemented a comprehensive and universal National Health Insurance (NHI) program to cover all inhabitants. This study aimed to assess the medical utilization by liver cancer patients under the NHI. Methods: This retrospective cross-sectional study used a sampled NHI research database, which contained 1 million beneficiaries. The claims of liver cancer patients in 2009 were analyzed. The other beneficiaries without liver cancer who used medical services in 2009 served as the control patients. Results: Among the 2335 identified liver cancer patients, 2178 (93.3%) patients used outpatient services and 1193 (51.1%) patients used inpatient services. Liver cancer accounted for 1.8% of the NHI’s total cost. The cost per visit was United States dollars (US$)59.30 for outpatient care and US$2070.30 for inpatient care. The annual cost per patient was US$4746.60; US$1951.00 were for outpatient care and US$2795.60 for inpatient care. Patients who were female, in their 60s, had a lower income, and lived in southern Taiwan had a higher cost per patient (p < 0.0001). Fees for consultation, treatment, and medical supplies (57.3%) accounted for the highest portion of outpatient costs, followed by drug fees (30.0%) and diagnosis fees (11.2%). Ward fees accounted for the highest portion of inpatient costs (19.0%), followed by drug fees (18.7%) and X-ray fees (14.9%). Private hospitals were visited more frequently than public hospitals. The cost per visit and cost per patient with liver cancer were 206.0% and 666.8%, respectively, of the cost of the control patients. Conclusion: The cost of liver cancer care is substantial and varies by sex, age, income, and geographic distribution. It is critical to reduce the incidence of liver cancer and identify cost-effective treatment strategies
