Background: Studies have indicated that patients infected with the SARS-CoV-2 virus fare worse clinically after a traumatic injury, especially those who are older and have other comorbidities.
Objective: This study aims to understand the effects of Corona Virus Disease 19 (COVID-19) diagnosis on patients undergoing surgery for hip fractures.
Methods: This is a retrospective review of the 2021 American College of Surgeons (ACS) National Surgical Quality Improvement Program (NSQIP) Targeted Hip Fracture database for patients who underwent surgery. Two cohorts were formed based on patients' preoperative COVID-19 status, as tested within 14 days prior to the operation. Several clinical factors were compared.
Results: The COVID-positive cohort consisted of 184 patients, all of whom had a laboratory-confirmed or clinically suspected SARS-CoV-2 infection, while the COVID-negative cohort consisted of 12,211 patients with no infection. A lower proportion of COVID-positive patients had an emergent operation compared to the COVID-negative cohort (58.70% vs. 73.09%, p < .001). Preoperatively, the COVID-positive cohort showed higher rates of coagulopathy/bleeding disorders (22.83% vs. 14.12%), congestive heart failure (16.30% vs. 9.84%), diabetes mellitus (28.26% vs. 19.24%), and dementia (42.39% vs. 28.07%), with p ≤ .005 for all. Postoperatively, a higher proportion of COVID-positive patients died (9.78% vs. 5.40%) or had pneumonia (8.70% vs. 3.65%), hospital readmission within 30 days (10.87% vs. 6.76%), and pressure sores (8.15% vs. 4.55%), with p ≤ .033 for all.
Conclusion: The diagnosis of COVID-19 in hip fracture patients was associated with higher rates of postoperative complications, including mortality, when compared to COVID-negative patients, indicating the severity of the viral infection.
