Journal ArticleDOI
Is volume related to outcome in health care? A systematic review and methodologic critique of the literature
TL;DR: A systematic review of the research evidence linking volume and outcome in health care is conducted, to summarize and describe the methodologic rigor of the existing literature, and to highlight the research and policy implications of these findings.
Journal ArticleDOI
Association of timing of surgery for hip fracture and patient outcomes.
Gretchen M. Orosz,Jay Magaziner,Edward L. Hannan,R. Sean Morrison,Kenneth J. Koval,Marvin Gilbert,Maryann McLaughlin,Ethan A. Halm,Jason J. Wang,Ann Litke,Stacey B. Silberzweig,Albert L. Siu,Albert L. Siu +12 more
TL;DR: Early surgery was not associated with improved function or mortality, but it was associated with reduced pain and LOS and probably major complications among patients medically stable at admission, and patients with hip fracture who are medically stable should receive early surgery when possible.
Journal ArticleDOI
Time to Clinical Stability in Patients Hospitalized With Community-Acquired Pneumonia Implications for Practice Guidelines
Ethan A. Halm,Michael J. Fine,Thomas J. Marrie,Christopher M. Coley,Wishwa N. Kapoor,D. Scott Obrosky,Daniel E. Singer +6 more
TL;DR: Estimates of time to stability in pneumonia and explicit criteria for defining stability can provide an evidence-based estimate of optimal length of stay, and outline a clinically sensible approach to improving the efficiency of inpatient management are outlined.
Journal ArticleDOI
An automated model to identify heart failure patients at risk for 30-day readmission or death using electronic medical record data.
Ruben Amarasingham,Billy J. Moore,Ying P. Tabak,Mark H. Drazner,Christopher Clark,Song Zhang,W. Gary Reed,Timothy S. Swanson,Ying Ma,Ethan A. Halm +9 more
TL;DR: Clinical and social factors available within hours of hospital presentation and extractable from an EMR predicted mortality and readmission at 30 days increased the model's accuracy, suggesting that such factors could enhance risk adjustment models designed to compare hospital readmission rates.
Journal ArticleDOI
Impact of Social Factors on Risk of Readmission or Mortality in Pneumonia and Heart Failure: Systematic Review
Linda Calvillo-King,Danielle Arnold,Kathryn J. Eubank,Matthew Lo,Pete Yunyongying,Heather Stieglitz,Ethan A. Halm +6 more
TL;DR: A broad range of social factors affect the risk of post-discharge readmission and mortality in CAP and HF, and older age and non-Whites had more readmissions after HF but decreased mortality.
