This study was designed to quantitatively assess the impact of deficiencies in completeness and precision of hospital case cost data on cost weight compression. For the nursing per diem model versus the nursing workload model the average compression was 19.6 percent (for the 25.9 percent of cases that changed cost weight by at least 5 percent). We concluded that the compression of case mix cost weights based on nursing per diem cost or per diem charge models, such as for U.S. diagnosis-related groups (DRGs), may be pervasive and material.
本研究旨在定量评估医院病例成本数据的完整性和精确性不足对成本权重压缩的影响。对于护理每日费用模型与护理工作量模型,平均压缩率为19.6%(对于成本权重至少变化5%的25.9%的病例)。我们得出结论,基于护理每日费用成本或每日收费模型(如美国诊断相关组(DRG))的病例组合成本权重压缩可能普遍存在且影响重大。
