Day of Admission is Associated With Variation in Geriatric Hip Fracture Care.

Abstract

The transition to bundled payment reimbursement for geriatric hip fractures has incentivized the identification of avoidable inefficiencies in the cost and quality of care. Although a "weekend effect" has been described with regard to hip fracture mortality, measures of efficiency according to the day of hip fracture admission are currently unclear. We identified 62,303 patients aged 65 years or older with a primary diagnosis of femoral neck or intertrochanteric hip fracture in the New York Statewide Planning and Research Cooperative System between 2009 and 2014. Outcome measures included preoperative delay, postoperative length of stay (LOS), and cost of admission. Preoperative delay was longer for weekend admissions, but shorter for admissions on Wednesday, Thursday, and Friday. Postoperative LOS was longer for admissions on Tuesday, Wednesday, and Thursday. Discharge rates varied considerably according to the day of admission, ranging from 12% to 43% by hospital day 4 and 53% to 72% by hospital day 6. No differences in cost according to day of admission were found once preoperative delay and postoperative LOS were accounted for. Notable variation exists in hospitalizations for geriatric hip fracture depending on the day of admission. Our data suggest the presence of a weekend effect, in which changes in staffing of surgical, medical, and ancillary services lead to increased waiting times for surgery for new admissions and delays in discharge of early- and mid-week admissions.
