报告内容摘要

As value-based purchasing (VBP) and patient-centered care take the center stage in today’s healthcare environment, healthcare organizations including hospitals are in an ongoing quest to improve care quality while containing rapidly rising costs. Among all healthcare professionals, nurses constitute the largest clinical subgroup in hospitals (American Nurse Association) and have profound impacts on care quality and hospital operating costs. Optimizing the level of nurse slack (i.e., the amount of nurse capacity relative to the amount of work performed), therefore, can have a significant impact on hospital performance. This research seeks to identify the fine-grained relationships between nurse slack and hospital operating performance with respect to care quality and operating costs. We also explore whether these relationships will be affected by the degree of competition in the local hospital market. Our analyses lead to several important findings: First, nurse slack initially is associated with improved care quality (measured by readmission rate) until it reaches a turning point, beyond which nurse slack is associated with worsen care quality, exhibiting a U-shaped relationship. Second, similar pattern applies to the relationship between nurse slack and operating costs, although the turning point is at a much lower nurse slack level. Third, market competition moderates the relationship between nurse slack and care quality so that the turning point of nurse slack will be higher when the degree of competition is higher. This shift of turning point also is observed in the relationship between nurse slack and operating costs. Collectively, the study findings point to three ranges of nurse slack in which hospitals will likely experience simultaneous improvements, a tradeoff, or simultaneous decline of care quality and operating cost when investing in  more nurse capacity.

Key words: slack, care quality, operating cost, U-shaped effect, tradeoff, market competition
