Perioperative multi-system optimization protocol in elderly hip fracture patients: a randomized-controlled trial.

Area of Science:

• Geriatric Medicine
• Surgical Outcomes
• Critical Care Medicine

Background:

• Hip fractures in the elderly are linked to high rates of postoperative morbidity and mortality.
• Optimizing perioperative care is crucial for improving outcomes in this vulnerable population.

Purpose of the Study:

• To evaluate the effectiveness of a perioperative multi-system optimization protocol in reducing postoperative complications in elderly patients with hip fractures.

Main Methods:

• Elderly patients (≥ 60 years) with hip fractures were randomized to an intervention group (goal-directed hemodynamic management, optimized pain and nutrition, oxygen therapy) or a control group (standard care).
• Postoperative complications, including cardiovascular, respiratory, neurologic, renal, and surgical events, were monitored during hospitalization.

Main Results:

• The primary outcome, incidence of at least one postoperative complication, was 39% in the intervention group versus 49% in the control group (RR, 0.79; P = 0.23), not reaching statistical significance.
• Secondary outcomes showed the intervention group received more fluid resuscitation (P < 0.001), had better mean arterial pressure control (P = 0.001), improved pain management (P < 0.001), and a potentially lower incidence of acute renal failure (P = 0.04).

Conclusions:

• The implemented perioperative multi-system optimization protocol did not significantly decrease postoperative complications in elderly hip fracture patients.
• The study may have been underpowered due to overestimation of the potential treatment effect, limiting the ability to demonstrate a significant benefit.
