Abstract
為有效控制醫療費用增長,國家健康保險署 (NHIA) 實施了臺灣住院診斷相關群組支付制度 (Tw-DRGs),以提高住院治療的品質並減少不必要的住院。本研究旨在探討 Tw-DRGs的實施是否會對住院治療品質產生負面影響? 因此,本研究評估了 2014 年 Tw-DRGs 第二階段實施 (Tw-DRGs-II) 對住院護理品質的影響;使用獨立樣本 t 檢定和邏輯回歸方法來分析每個醫院層級 (從 2007 年至 2017 年第三季度)的醫療指標。研究結果顯示,Tw-DRGs-II 對住院治療品質產生了負面影響。根據獨立樣本 t 檢定,Tw-DRGs-II 實施後在所有醫院層級中,均對 14 天非計畫再住院率 (URA-14) 產生了顯著負面影響。但三天內急診室重返率 (RES-3)沒有顯示相符的結果,且學術醫療中心和區域醫院的品質水平在 Tw-DRGs-II 實施後有明顯下降。根據邏輯回歸的結果,兩個指標顯示 Tw-DRGs-II 對不同級別的醫院的住院治療品質產生了顯著負面影響,包括全院群、醫療中心和區域醫院,但地區醫院除外。此外本研究也使用廣義估計方程式 (GEE) 做為分析比較的參考。總之,Tw-DRGs-II 對住院治療品質產生了負面影響。因此,建議行政部門在 Tw-DRGs-II 實施後加強監督,防止數據欺詐,並提供更大的激勵措施以提高住院治療的品質。
To effectively control the growth of medical expenses, the National Health Insurance Administration (NHIA) has implemented the Taiwan inpatient diagnosis-related groups payment system (Tw-DRGs) to improve the quality of inpatient care and reduce unnecessary hospitalization. This study aims to explore the implementation of Tw-DRGs would adversely affect the quality of inpatient care? Therefore, the impact of Tw-DRGs second phase implementation (Tw-DRGs-II) in 2014 on the quality of inpatient care is assessed
independent t-test and logistic regression methods are used to analyze the medical indicators at each level of hospitals (from 2007 to the third quarter of 2017). We found that Tw-DRGs-II has a negative impact on the quality of inpatient care. Based on independent t-test, a significant effect on increasing the 14-day unplanned readmission rate (URA-14) at all levels of hospitals after the Tw-DRGs-II implementation is found. However, the three-day emergency room (ER) revisit rate (RES-3) did not show matching results, and the quality level of academic medical centers and metropolitan hospitals decreased significantly after the Tw-DRGs-II implementation. Based on the results of logistic regression, two indicators show that the Tw-DRGs-II significantly affects the quality of inpatient services in hospitals at different levels, including the all-hospital group, academic medical centers, and metropolitan hospitals, except local community hospitals. Furthermore, this study also employed Generalized Estimating Equations (GEE) as a reference for comparative analysis. In conclusion, Tw-DRGs-II adversely affects the quality of inpatient care. Therefore, we recommend that the executive branch strengthen supervision after the implementation of Tw-DRGs-II to prevent data fraud and provide greater incentives to improve the quality of inpatient care.
