Journal ArticleDOI
Association of the Hospital Readmissions Reduction Program With Mortality During and After Hospitalization for Acute Myocardial Infarction, Heart Failure, and Pneumonia.
Rohan Khera,Kumar Dharmarajan,Yongfei Wang,Zhenqiu Lin,Susannah M. Bernheim,Yun Wang,Sharon-Lise T. Normand,Harlan M. Krumholz +7 more
TL;DR: There was no evidence for increase in in-hospital or postdischarge mortality associated with the HRRP announcement or implementation—a period with substantial reductions in readmissions.
Journal ArticleDOI
Hospital readmission performance and patterns of readmission: retrospective cohort study of Medicare admissions
Kumar Dharmarajan,Angela F. Hsieh,Zhenqiu Lin,Héctor Bueno,Joseph S. Ross,Leora I. Horwitz,José Augusto Barreto-Filho,Nancy Kim,Lisa G. Suter,Susannah M. Bernheim,Elizabeth E. Drye,Harlan M. Krumholz +11 more
TL;DR: High performing hospitals have proportionately fewer 30 day readmissions without differences in readmission diagnoses and timing, suggesting the possible benefit of strategies that lower risk of readmission globally rather than for specific diagnoses or time periods after hospital stay.
Journal ArticleDOI
Readmissions after hospitalization for heart failure, acute myocardial infarction, or pneumonia among young and middle-aged adults: a retrospective observational cohort study
Isuru Ranasinghe,Yongfei Wang,Kumar Dharmarajan,Angela F. Hsieh,Susannah M. Bernheim,Harlan M. Krumholz +5 more
TL;DR: Readmissions after hospitalization for heart failure, acute myocardial infarction, or pneumonia in adults aged 18 to 64 years with readmissions in those aged 65 and older are compared.
Journal ArticleDOI
Hospital-Readmission Risk - Isolating Hospital Effects from Patient Effects.
Harlan M. Krumholz,Kun Wang,Zhenqiu Lin,Kumar Dharmarajan,Leora I. Horwitz,Joseph S. Ross,Elizabeth E. Drye,Susannah M. Bernheim,Sharon-Lise T. Normand +8 more
TL;DR: The findings suggest that hospital quality contributes in part to readmission rates independent of factors involving patients.
Journal ArticleDOI
Variation Exists in Rates of Admission to Intensive Care Units for Heart Failure Patients Across Hospitals in the United States
Kyan C. Safavi,Kumar Dharmarajan,Nancy Kim,Kelly M. Strait,Shu-Xia Li,Serene I. Imperia Chen,Tara Lagu,Harlan M. Krumholz +7 more
TL;DR: ICU admission rates for HF varied markedly across hospitals and lacked association with in-hospital risk-standardized mortality, suggesting judicious ICU use could reduce resource consumption without diminishing patient outcomes.
