评估出院住院病人对医院护理评估的调查模式调整的必要性，并制定相应的调整措施。来自2006年全国随机抽样的45家医院的555名受访者完成了CAHPS（（R））医院（HCAHPS [医院消费者对医疗保健提供者和系统的评估]）调查：我们估计线性模型中的模式效应，该模型预测医院固定效应和患者组合调节器的每个HCAHPS结局。与随机分配到邮寄和混合（邮寄与电话随访）模式的患者相比，模式提供了更积极的评价，某些效果相当于医院排名中超过30个百分点。模式效应在医院之间是一致的，并且通常大于总的患者组合效应。患者组合调整说明了任何无应答偏倚，这些偏倚可以通过加权来解决。医院绩效的有效比较要求报告的医院评分根据调查模式和患者组合进行调整。
To evaluate the need for survey mode adjustments to hospital care evaluations by discharged inpatients and develop the appropriate adjustments.A total of 7,555 respondents from a 2006 national random sample of 45 hospitals who completed the CAHPS((R)) Hospital (HCAHPS [Hospital Consumer Assessments of Healthcare Providers and Systems]) Survey.We estimated mode effects in linear models that predicted each HCAHPS outcome from hospital-fixed effects and patient-mix adjustors.Patients randomized to the telephone and active interactive voice response (IVR) modes provided more positive evaluations than patients randomized to mail and mixed (mail with telephone follow-up) modes, with some effects equivalent to more than 30 percentile points in hospital rankings. Mode effects are consistent across hospitals and are generally larger than total patient-mix effects. Patient-mix adjustment accounts for any nonresponse bias that could have been addressed through weighting.Valid comparisons of hospital performance require that reported hospital scores be adjusted for survey mode and patient mix.
