dc.description.abstract | 本研究係比較採用國外診斷群組分
類系統所建構之風險計價模式,及以本研
究所發展台灣本土診斷群組分類系統,所
建立台灣診斷基礎風險計價模式,運用在
台灣全民健康保險制度下,國內外不同診
斷群組分類系統所建立之風險計價模
式,對風險校正模式預測力之影響,及其
妥適性進行探討。
研究資料為國家衛生研究院全民健
康保險研究資料庫承保抽樣歸人20 萬人
資料檔,並選取承保資料中保險對象2000
與2002 年的全年納保之保險對象,研究
樣本為164,275 人,並擷取其門診及住院
醫療費用申報等相關資料。診斷群組建構
之風險計價模式,採用目前國際上廣泛被
採用之ACGs 模式(Adjusted Clinical
Groups model) 、DCG/HCC 模式
(Diagnostic Cost Group/Hierarchical
Condition Categories model),以及由本研
究所發展之門診診斷群組TASGs(Taiwan
Ambulatory Spending Groups)與住院診斷
群組TPIPDCGs(Taiwan Principal Inpatient
Diagnostic Groups),並預估各模式對2001
年及2002 年之醫療費用費用預測力;為
避免以相同資料進行建構模式與評估模
式預測力可能產生之過度估計問題,本研
究將研究樣本隨機分割為二子樣本,以估
計子樣本建立風險計價模式,而以預測子
樣本驗證所建立之風險計價模式的準確
性。
研究結果顯示,在門診費用預測力部
分, ACGs 模式為10.28%~11.2% 、
DCG/HCC 模式為8.85~9.49% 、
TASGs+TPIPDCG 模式為
20.37%~20.92%,在整體費用(門診與住院
合計) 預測力部分, ACGs 模式為
9.38%~10.56% 、DCG/HCC 模式為
7.44~8.29% 、TASGs+TPIPDCG 模式為
22.7%~24.76%,不論在門診費用或整體費
用之預測力,均以運用本土發展之診斷群
組分類系統預測力最高,而國外診斷群組
分類系統ACGs 模式預測力高於
DCG/HCC 模式。而ACGs 與DCG/HCC
模式運用在台灣全民健康保險制度下,其
預測力均相當穩定,顯示其運用於台灣全
民健康保險資料具相當的可適用性,惟國
外診斷群組分類系統均較本土發展系統
其預測力為低,顯示在導入國外診斷群組
分類系統時,應考量我國特性進行本土化
的修正。 | zh_TW |
dc.description.abstract | This study intends to develop a diagnostic information risk adjustment
model, and to examine the performance
of ACG and DCG/HCC systems in
Taiwan National Health Insurance
program. Assess the extent to which ACG
and DCG/HCC can account for
same-year and next-year outpatient and
total health care expenditures.
A total of 164,275 beneficiaries,
eligible for the National Health Insurance
(NHI) from January 1, 2000 to December
31, 2002 were randomly selected from
the enrollment file of National Health
Insurance Research Database. ACG,
DCG/HCC and TASGs+TPIPDCG were
assigned through diagnoses from
physician and hospital claim files. We use
2000 and 2001 diagnostic profiles to
predict costs in 2001 and 2002,
respectively. Linear regression was used
to examine the predictability of the ACGs,
DCG/HCC, TASGs+TPIPDCG systems
to explain variation in individual costs. In
order to avoid overfitting, a split-sample
method was employed to partition the
study sample into an estimation sample
and a validation sample randomly.
For Outpatient cost, while the ACGs
system explained 12.87%~11.2%, the
DCG/HCC system explained
10.24%~9.49%, and the
TASGs+TPIPDCG system explained
20.92%~20.37% of variation in costs. For
total cost, while the ACG system
explained 15.43%~10.56%, the
DCG/HCC system explained
11.5%~8.29%, and the
TASGs+TPIPDCG system explained
24.76%~22.7% of variation in costs. The
TASGs+TPIPDCG system performs
better than ACGs and DCG/HCC system.
The ACG system performs better than
DCG/HCC system in Taiwan National
Health Insurance program. The
predictabilities of both ACG and
DCG/HCC systems are fairly stable in
the same-year and next-year costs. The
results demonstrate that the application of
ACG and DCG/HCC in Taiwan is
feasible using existing data. Relative to
the applications in other countries, the
ability of the ACG and DCG/HCC
systems to explain variation in costs is
comparatively low. It is suggested that
the introduction of the ACG and
DCG/HCC systems into Taiwan requires
some modifications in order to harmonize
with local practice and disease patterns. | en |
