Outpatient surgeries are often touted for offering equal and in some cases better results as inpatient procedures. In the case of surgical fixation of isolated ankle fracture, outpatient safety data has been limited until now.
According to a new study, “Outpatient Versus Inpatient Surgical Fixation of Isolated Ankle Fractures: An Analysis of 90-Day Complications, Readmissions, and Costs,” recently published in May-June 2020 issue of The Journal of Foot & Ankle Surgery, for select patients, outpatient surgery to fix an ankle fracture can be safe and more cost-effective.
The researchers created an outpatient and inpatient cohort from the 2007 to 2014 Humana Administrative Claims Database. All patients had undergone open reduction internal fixation for unimalleolar, bimalleolar, or trimallelolar isolated closed ankle fractures.
Both cohorts were matched by age, sex, race, region, fracture type and Elixhauser Comorbidity Index. Overall, there were a total of 5,317 inpatient-treated and 6,941 outpatient-treat closed ankle fractures.
The results showed that patients with outpatient ankle fractures compared with inpatient ankle fractures, had lower rate of pneumonia (2.2% vs. 4.0%; p < .001), myocardial infarction (0.9% vs. 1.8%; p =.005), acute renal failure (2.2% vs. 5.3%; p < .001), urinary tract infections (7.4% vs. 12.3%; p < .001), and pressure ulcers (0.9% vs. 2.0%; p = .001).
The outpatient patients also had lower rates of 90-day readmissions (9.7% vs. 14.1%; p < .001) and emergency department visits (13.8% vs. 16.2%; p = .028). In addition, overall 90-day costs for outpatient ankle fractures were nearly $9,000 lower than costs for inpatient ankle fractures ($12,923 vs $21,866; p < .001).
The researchers wrote, “Based on our findings, it appears that outpatient treatment of ankle fractures can be deemed safe and feasible in a select cohort of patients.”
Patients at high risk for complications data shows tend to do better with inpatient surgery where they can be more closely monitored.
