Both cost and quality of healthcare are major concerns in the United States. Using patient satisfaction as a quality indicator, we seek to identify the relationship between healthcare cost and quality from the perspective of the community-dwelling population in the United States.
We examined a nationally representative sample of 13,980 adults (age >or= 18 years) in the 2003 Medical Expenditure Panel Survey (MEPS). Given the idiosyncrasies of the cost data distribution, a recently developed extended estimating equation (EEE) model was employed to identify the relationship between patient satisfaction and healthcare expenditure, after controlling for individual demographic covariates, co-morbidity profile, and functional and activity limitations. A series of sensitivity analyses were conducted, in addition, to verify the identified relationship. All statistics were adjusted using the proper sampling weight from the MEPS data.
Average annual healthcare expenditures for 2003 ranged between $3923 and $6073 when grouped by patient satisfaction ratings with a mean value $4779 for all individuals who rated perceived satisfaction of their healthcare. We found that there is no statistically significant relationship between patient satisfaction and total healthcare expenditure (p = 0.60) and a non-monotonic relationship is not identified either. All sensitivity analyses results revealed a lack of relationship between patient satisfaction and healthcare expenditures.
Patient satisfaction might not reflect the quality of healthcare from an objective clinical standpoint. The identified cost-satisfaction relationship may not be extrapolated to other quality indicators. Due to the cross-sectional study design, no causal relationship could be inferred between patient satisfaction and healthcare expenditure.
Our study adds to the literature on health care cost and quality by suggesting that the improvement of patient satisfaction may not require additional health care spending.
医疗保健的成本和质量都是美国的主要关注点。我们以患者满意度作为质量指标,试图从美国社区居民的角度确定医疗保健成本与质量之间的关系。
我们在2003年医疗支出小组调查(MEPS)中研究了一个具有全国代表性的13980名成年人(年龄≥18岁)的样本。鉴于成本数据分布的特殊性,在控制了个体人口统计学协变量、共病情况以及功能和活动限制后,采用最近开发的扩展估计方程(EEE)模型来确定患者满意度与医疗保健支出之间的关系。此外,还进行了一系列敏感性分析以验证所确定的关系。所有统计数据均使用MEPS数据中的适当抽样权重进行调整。
按患者满意度评分分组时,2003年的平均年度医疗保健支出在3923美元至6073美元之间,所有对其医疗保健满意度进行评分的个体的平均值为4779美元。我们发现患者满意度与总医疗保健支出之间没有统计学上的显著关系(p = 0.60),也未发现非单调关系。所有敏感性分析结果均显示患者满意度与医疗保健支出之间缺乏关联。
从客观临床角度来看,患者满意度可能无法反映医疗保健的质量。所确定的成本 - 满意度关系可能无法外推至其他质量指标。由于采用横断面研究设计,无法推断患者满意度与医疗保健支出之间的因果关系。
我们的研究表明提高患者满意度可能不需要额外的医疗保健支出,这为有关医疗保健成本和质量的文献增添了内容。
