Note: Successful community discharge was defined as being discharged to the community from post-acute care and remaining in the community at least 30 days.
Q1= Lowest quartile
Q2= Second quartile
Q3= third quartile
Q4= highest quartile
PAC=post-acute care
SD= standard deviation
IRF=inpatient rehabilitation facility
SNF=skilled nursing facility
Occurrence of hospital complications during index hip fracture acute care stay includes: postoperative deep venous thrombosis and pulmonary embolism, postoperative myocardial infarction, or postoperative hemorrhage.
Provider level analysis was limited to those facilities that had at least 4 hip fracture admissions in 2006.
ANOVA and Chi square analysis were conducted to evaluate whether or not there was a statistically significant differences between quartile groups. All variables were significantly different across groups (p<0.01) with exception of one variable indicated with an *
there was no statistical difference between quartile groups for this variable
