Impact of orthogeriatric management on the average length of stay of patients aged over seventy five years admitted to hospital after hip fractures.

introductionHip fracture is a frequent and serious condition in the elderly. We conducted a retrospective cohort study to answer the following questions: (1) Could treatment in an orthogeriatric unit help to reduce the average length of stay for patients aged over 75 years admitted to hospital for the treatment of a hip fracture?; and (2) Could such treatment influence the post-operative outcomes of patients with hip fracture? METHODS AND MATERIALS: Our study included 534 patients admitted to hospital between January 2017 and December 2018 for surgical treatment of a hip fracture. We compared 246 patients who received traditional orthopaedic care with 288 patients treated in an orthogeriatric unit.

resultsOur cohort included 410 women (77%). The average age was 87.5 ± six years, and 366 patients (68%) were living at home prior to the fracture. A statistically significant difference in median length of stay (from 10 to 9 days) was observed between patients who did and did not receive orthogeriatric unit treatment (groups 1 and 2; 95% CI: 0.64; 2.59; p = 0.001). There was no difference in pre-operative delay, intra-hospital mortality rate, place of recovery, rate of institutionalisation after six months, or the number of new fractures at 6 months between the groups. The mortality rate after six months was 23.6% and 21.3% in groups 1 and 2, respectively; the difference was not significant. DISCUSSION: Orthogeriatric unit treatment reduced the median length of stay by one day, in line with most previous studies. According to Pablos-Hernandez et al., multifaceted orthogeriatric treatment is most effective. In our study, only 38% of the patients received surgical treatment within 48 hours, where early surgery is key for reducing the length of hospital stay. The intrahospital mortality rate was 2.6%, which is comparable to literature data. The discharge rate did not differ by orthogeriatric treatment status, which is also consistent with previous findings (e.g. Gregersen et al.). Lastly, the mortality rate after six months was slightly reduced by orthogeriatric care. In line with this, Boddaert et al. reported a difference in mortality rate after six months between groups who did and did not receive orthogeriatric treatment (15% vs. 24%).
