Abstract
|
|
|
The hospital, clinical department and the Physician factor in explaining variations of hospital resource use in surgically admitted patients was compared. This analysis was based on 6,361 discharges in 28 hospitals for three surgical conditions - lens procedures, anal and stomal procedures, uterine and ovarian procedures using medical insurance claim data.
The results were as follow:
1. Regression analysis indicated that the hospital and clinical department characteristics, Such as hospital ownership and size, were more significant predictors of the resource use indicators than the physician and patients´ social characteristics.
2. Regarding to the physician factors, the hospital where the physician received the residency training and the medical school where he/she graduated had less effect compared to the hospitals where he/she currently works. Between the residency trained hospital medical school, the former is more important than the latter.
3. When the hospital charges were divided into type of service provided i. e. room, drug, laboratory & radiologic, procedure & operation, and anesthesic charges, variance due to the hospital factor was larger than that due to the physician factor in each item.
In summary, the hospital and clinical departmental factor played an important role than physician factor: indicating to reduce the variation in hospital resource use, the policy that affects hospital behavior would be more effective than that targets individual physician behavior.
