Plantinga LC, et al. - In this retrospective cohort study, researchers used national registry data to determine the national burden of, and identify correlates of, readmissions associated with pulmonary edema among hemodialysis patients. A total of 215,251 US hemodialysis patients with index admissions while under Medicare primary coverage in 2011–13 were examined, using multivariable logistic regression models. They found hemodialysis patients commonly sought readmissions due to pulmonary edema. A pulmonary edema-related index admission was identified as the strongest independent correlate of pulmonary edema-related readmission. The overall readmissions could be substantially influenced by interventions aimed at preventing such readmissions, particularly targeted at incident hemodialysis patients with a prior history of heart failure and patients initially admitted for pulmonary edema.
