Takeaway

  • After trochanteric fracture, 6-month mortality in the elderly is linked to risk factors that include UTI, blood transfusions in the intraoperative period, and acute renal failure.

Why this matters

  • Some of these risk factors, such as surgical site infection and UTI, are preventable.

Study design

  • Cross-sectional cohort study (N=275) of patients with trochanteric fracture (2008-2015).
  • Data were collected at the time of surgery and with telephone follow-up at 6 postoperative months.
  • Funding: Suplemedicos S.A.; other.

Key results

  • Mean age: 79.9 years.
  • 16% of the cohort died within 6 months of surgery.
  • Greater risk for death (unadjusted ORs; 95% CIs) was seen in patients with:
    • Surgery after 48 hours: 2.1 (1.02-4.06).
    • Acute renal failure: 3.4 (1.3-8.8).
    • Receipt of blood transfusions in the intraoperative period: 4.4 (1.7-11.8).
    • Postoperative UTI: 7.1 (2.1-24.5).
    • Surgical site infection: 5.6 (1.1-28.5).

Limitations

  • Single-center study.
  • Cross-sectional, observational design.
