摘要


台灣版的DRGs從第一版的499個DRGs,發展到第三版的969個DRGs,是否足以解釋資源耗用的程度與提供醫療院所合理的支付?成為值得探討的議題。本研究以變異係數(coefficient of variation ,CV)與決定係數(coefficient of determination,R2  值)的測量,檢視台灣第三版DRGs各組DRG之組內資源耗用變異情形,以及探討各DRGs的支付制度,可解釋依變項(醫療資源)的程度。 研究發現:(1)探討出827組有病例DRGs之申報費用和住院日數的變異係數與解釋力,以及各組MDC的解釋力。全部DRGs費用解釋力為0.395,住院日數解釋力為0.714 DRGs變異係數與解釋力Pearson相關呈負相關,在顯著水準為0.01時(P<0,01)有顯著相關。(2)個別DRG之解釋力可作為未來Tw-DRGs版本調整與修訂的參考。(3)MDC4、MDC10、MDC17費用解釋力都在0.2以下,應在未來提高解釋能力。(3)第一版Tw-DRGs 費用解釋力最低前三名的DRGs在第三版都已增加組數再分類了,費用解釋力只有0.3左右,增加的組數是否合宜,分類的邏輯是否再修正,應設法提高解釋力。 建議:(1)Tw-DRGs目前雖然暫緩實施,但在未來期望Tw-DRGs的版本,能針對解釋力低的DRG作調整與修訂,使其更能提供合理的支付,使醫療資源能更合理的分配。(2)台灣DRGs的版本再修訂應可增加CC的層次結構,真實的呈現疾病嚴重度,使支付制度有合理的給付,避免資源的浪費。(3)台灣應成立專責獨立的醫療品質審查機構,監督保險醫事服務機構所提供的醫療服務之適當性,保護民眾就醫的權益。

The purpose of this study was to assess the adequacy of the third version of Tw-DRGs. The adequacy was determined by calculating the coefficient variation (CV) and the coefficient of determination (R2) of the charges and lengths of stay (LOS). The research data were derived from the 2006 National Health Insurance Research Database of the National Health Research Institute. This research found (1) For both the charges and LOS of 827 DRGs, the overall charge explanation value is 0.395 and LOS explanation is 0.714. There are significant negative correlations between CV and R2   (p<0.01) for both the charge and LOS. (2)The individual DRG explanation could be used as the reference for future Tw-DRG version revised. (3) How to increase the charge explanation values for MDC4, MDC10, and MDC17 is needed, as there are all below 0.2. (4) To increase the charge explanation value, the third version DRGs adjusted and reclassified the three lowest groups in the first version, however, it was only increased to about 0.3; more suitable classification logic is needed for future revision. Suggestion: (1) Although Tw-DRGs is postponed for implementation at present, we should focus on the low DRG explanation to make the revision, enable it to provide a reasonable payment and more reasonable assignment of medical resources in the future version. (2) After the Tw-DRGs versions are revised, it should be possible to increase the CC level and present the actual disease severity. Hence, there is reasonable payment and wasted resources are avoided. (3) Taiwan should establish an independent institution for medical service investigation. This independent institution would be responsible for appropriate surveillance of medical services provided by the medical service insurance organization to protect the rights of people asking for medical care.
