Mortality in hip fracture patients after implementation of a nurse practitioner-led orthogeriatric care program: results of a 1-year follow-up

Background: Hip fractures are a major cause of mortality and disability in frail older adults. Therefore, orthogeriatrics has been embraced to improve patient outcomes. With the optimal template of orthogeriatric care still unknown, and to curtail rising healthcare expenditure we implemented a nurse practitioner-led orthogeriatric care program (NPOCP). The objective was to evaluate NPOCP by measuring 3-month and 1-year mortality, compared to usual care (UC). In addition, length of stay (LOS) and location of hospital discharge were reported. Methods: An anonymised data set, of hip fracture patients (n = 300) who presented to Maastricht University Medical Centre, the Netherlands, a level-1 trauma centre, was used. NPOCP was implemented on one of two surgical wards, while the other ward received UC. Patient allocation to these wards was random. Results: In total, 144 patients received NPOCP and 156 received UC. In the NPOCP, 3-month and 1-year mortality rates were 9.0% and 13.9%, compared to 24.4% and 34.0% in the UC group (P < 0.001). The adjusted hazard ratio (aHR) for 3-month (aHR 0.50 [95%CI: 0.26-0.97]) and 1-year mortality (aHR 0.50 [95%CI: 0.29-0.85]) remained lower in NPOCP compared to UC. Median LOS was 9 days [IQR 5-13] in patients receiving UC and 7 days [IQR 5-13] in patients receiving NPOCP (P = 0.08). Thirty-eight (27.5%) patients receiving UC and fifty-seven (40.4%) patients receiving NPOCP were discharged home (P = 0.023). Conclusion: Implementation of NPOCP was associated with significantly reduced mortality in hip fracture patients and may contribute positively to high-quality care and improve outcomes in the frail orthogeriatric population.
