title: The soaring mechanic ventilator utilization under a universal health insurance in Taiwan.
abstract: OBJECTIVE
  The use of mechanic ventilators (MVs) is increasing in many countries. Taiwan's Bureau of National Health Insurance (NHI) launched a new payment program in 2000 to encourage integrated care for mechanically ventilated patients and to reduce the heavy utilization of high-cost intensive care unit. This study examines the trend in MV usage in Taiwan.
  
  
  METHODS
  This study used nationally representative NHI claim data from 1997 to 2004 to examine the MV usage. Total inpatient days and MV usage days were analyzed by piece-wise regression model. We also analyzed the major diagnoses related to MV dependence.
  
  
  RESULTS
  While the total hospital inpatient days increased only 49.41%, MV usage rose 181.75% over the 8-year study period. The increase in number of MV patient-days in ICUs has not been curbed, besides there was an increase in respiratory care center/wards. Acute respiratory failure (ARF), pneumonia and diabetes mellitus were the leading diagnoses for mechanically ventilated patients.
  
  
  CONCLUSIONS
  The new NHI insurance payment program may have helped spark the increased trend in MV usage in Taiwan. The significant impact of insurance incentive on healthcare utilization is a critical issue for policymakers in developing healthcare programs.
