Key result
Lower-volume hospitals were associated with a 10% to 20% higher adjusted risk of inpatient mortality for Medicare patients with intertrochanteric hip fractures compared to highest-volume hospitals.

Hospital volume-mortality association in hip fractures should not yet alter referrals; extends volume-outcome data but remains hypothesis-generating.

Does higher provider volume reduce inpatient through 90-day mortality in Medicare beneficiaries undergoing surgery for intertrochanteric hip fracture?
Unlike elective arthroplasty, routine intertrochanteric hip fractures do not necessarily need to be directed exclusively to high-volume centers, as mortality benefits are largely limited to the inpatient period and the lowest-volume centers.
Forte et al. (2010) conducted a cohort in Intertrochanteric hip fracture (n=192,365). Lower hospital and surgeon procedure volume vs. Highest-volume hospitals and surgeons was evaluated on Inpatient through 90-day postoperative mortality. Lower-volume hospitals were associated with a 10% to 20% higher adjusted risk of inpatient mortality for Medicare patients with intertrochanteric hip fractures compared to highest-volume hospitals.
