According to the report of the Bureau of National Healthcare Insurance (NHI) in 1997, the total expenses on ventilator-dependent patients was about 7,100 million yuan in hospital, account for 3% of the cost of one year of health insurance of the whole people. To efficiently control their admission so as to decrease unsuitable utilization of mechanical ventilation, and to achieve the rational growth of medical expenditure, the NHI has developed the perspective payment system for the ventilator-dependent integrated delivery system (IDS) respiratory care program since July 1, 2000. Ventilator-dependent patients, difficult to wean, rely on the mechanical ventilation, using for at least 21 days in succession. The patients are dependent upon long-term mechanical respiratory care. Integrating the different level of respiratory care, IDS program is including ¡§ICU , intensive care unit¡¨, ¡¨RCC, respiratory care center¡¨, ¡¨ RCW , respiratory care ward¡¨ and ¡§home care¡¨ and pay in accordance with the level. The purpose of IDS program is to promote the quality of respiratory care and effectively to utilize the limited medical resources. The data for this research was retrieved from the 2002-2004 ¡§NHI database¡¨ that includes charge and discharge information for 115 hospitals. Of the 115 hospitals analyzed using data envelopment analysis (DEA) technique, to explore the whole efficiency and purely technological efficiency.
