Skilled nursing facility (SNF) volume effect on probability of successful 30-day discharge to the community stratified according to outcome risk. The low-risk stratum consists of participants with the four risk factors most associated with successful 30-day discharge to the community: no diagnosis of cognitive impairment or Alzheimer’s or other dementia, having a femoral neck fracture, not living alone at the time of the hip fracture, and having an index hospital stay of less than 7 days. The non-low-risk stratum includes the remaining participants, who had one or more of these four risk factors at SNF admission.
