  • * Unless otherwise stated.

  • Mortality data postdischarge are not available for patients discharged after Dec. 1, 2011; thus, these patients are excluded from this calculation.

  • Denominator excludes patients who died during index admission to hospital.

  • § Physician-adjusted length of stay obtained from generalized linear mixed model containing physician experience group (fixed effect) and controlling for physician as a random effect.

  • Patient- and physician-adjusted length of stay obtained from same generalized linear mixed model with physician as a random effect, but also including age, sex, Charlson Comorbidity Index score, hospital, time period (2011–2012 v. 2009–2010) and hospital × time period interaction.
