The relationship between quality of care and the cost of the nursing workforce is of concern to policymakers. This study assesses the evidence for a relationship between the nursing workforce and patient outcomes in the acute sector through a systematic review of international research produced since 1990 involving acute hospitals and adjusting for case mix. Twenty-two large studies of variable quality were included. They strongly suggest that higher nurse staffing and richer skill mix (especially of registered nurses) are associated with improved patient outcomes, although the effect size cannot be estimated reliably. The association appears to show diminishing marginal returns.
护理质量与护理劳动力成本之间的关系是政策制定者所关注的。本研究通过对1990年以来涉及急症医院并针对病例组合进行调整的国际研究进行系统综述，评估急症部门护理劳动力与患者结局之间关系的证据。纳入了22项质量参差不齐的大型研究。这些研究有力地表明，更高的护士配备和更丰富的技能组合（尤其是注册护士）与改善患者结局相关，尽管效应大小无法可靠估计。这种关联似乎呈现出边际收益递减的趋势。
