We investigate differences in patients' length of stay between National Health Service (NHS) public hospitals, specialised public treatment centres and private treatment centres that provide elective (non-emergency) hip replacement to publicly funded patients. We find that the specialised public treatment centres and private treatment centres have, on average, respectively 18% and 40% shorter length of stay compared with NHS public hospitals, even after controlling for differences in age, gender, number and type of diagnoses, deprivation and regional variation. Therefore, we interpret such differences as because of efficiency as opposed to selection of less complex patients. Quantile regression suggests that the proportional differences between different provider types are larger at the higher conditional quantiles of length of stay.
我们研究了国民保健制度（NHS）公立医院、专门的公立治疗中心和为公费患者提供择期（非紧急）髋关节置换手术的私立治疗中心之间患者住院时间的差异。我们发现，即使在控制了年龄、性别、诊断数量和类型、贫困程度和区域差异等因素后，专门的公立治疗中心和私立治疗中心的平均住院时间分别比 NHS 公立医院短 18%和 40%。因此，我们认为这些差异是由于效率的原因，而不是选择了病情不太复杂的患者。分位数回归表明，在住院时间的较高条件分位数上，不同提供者类型之间的比例差异更大。
