Relationship between patient satisfaction with inpatient care and hospital readmission within 30 days.

OBJECTIVES: To determine whether hospitals where patients report higher overall satisfaction with their interactions among the hospital and staff and specifically their experience with the discharge process are more likely to have lower 30-day readmission rates after adjustment for hospital clinical performance. STUDY DESIGN: Among patients 18 years or older, an observational analysis was conducted using Hospital Compare data on clinical performance, patient satisfaction, and 30-day risk-standardized readmission rates for acute myocardial infarction, heart failure, and pneumonia for the period July 2005 through June 2008. METHODS: A hospital-level multivariable logistic regression analysis was performed for each of 3 clinical conditions to determine the relationship between patient-reported measures of their satisfaction with the hospital stay and staff and the discharge process and 30-day readmission rates, while controlling for clinical performance. RESULTS: In samples ranging from 1798 hospitals for acute myocardial infarction to 2562 hospitals for pneumonia, higher hospital-level patient satisfaction scores (overall and for discharge planning) were independently associated with lower 30-day readmission rates for acute myocardial infarction (odds ratio [OR] for readmission per interquartile improvement in hospital score, 0.97; 95% confidence interval [CI], 0.94-0.99), heart failure (OR, 0.96; 95% CI, 0.95-0.97), and pneumonia (OR, 0.97; 95% CI, 0.96-0.99). These improvements were between 1.6 and 4.9 times higher than those for the 3 clinical performance measures. CONCLUSIONS: Higher overall patient satisfaction and satisfaction with discharge planning are associated with lower 30-day risk-standardized hospital readmission rates after adjusting for clinical quality. This finding suggests that patient-centered information can have an important role in the evaluation and management of hospital performance.

Economic evaluation of the benefits of reducing acute cardiorespiratory morbidity associated with air pollution.

BACKGROUND: Few assessments of the costs and benefits of reducing acute cardiorespiratory morbidity related to air pollution have employed a comprehensive, explicit approach to capturing the full societal value of reduced morbidity. METHODS: We used empirical data on the duration and severity of episodes of cardiorespiratory disease as inputs to complementary models of cost of treatment, lost productivity, and willingness to pay to avoid acute cardiorespiratory morbidity outcomes linked to air pollution in epidemiological studies. A Monte Carlo estimation procedure was utilized to propagate uncertainty in key inputs and model parameters. RESULTS: Valuation estimates ranged from 13 dollars (1997, Canadian) (95% confidence interval, 0-28 dollars) for avoidance of an acute respiratory symptom day to 5,200 dollars (4,000 dollars-6,400 dollars) for avoidance of a cardiac hospital admission. Cost of treatment accounted for the majority of the overall value of cardiac and respiratory hospital admissions as well as cardiac emergency department visits, while lost productivity generally represented a small proportion of overall value. Valuation estimates for days of restricted activity, asthma symptoms and acute respiratory symptoms were sensitive to alternative assumptions about level of activity restriction. As an example of the application of these values, we estimated that the observed decrease in particulate sulfate concentrations in Toronto between 1984 and 1999 resulted in annual benefits of 1.4 million dollars (95% confidence interval 0.91-1.8 million dollars) in relation to reduced emergency department visits and hospital admissions for cardiorespiratory disease. CONCLUSION: Our approach to estimating the value of avoiding a range of acute morbidity effects of air pollution addresses a number of limitations of the current literature, and is applicable to future assessments of the benefits of improving air quality.
