Abstract

Introduction: The COVID-19 pandemic has spread globally and placed healthcare systems under substantial strain. Hip fracture patients represent a high-risk population for severe COVID-19 symptoms, as they are generally older with multiple medical comorbidities. There has been limited information available on the presenting characteristics and outcomes of COVID-positive patients with hip fractures who undergo surgical treatment.

Methods: This was a retrospective study of 10 patients ≥60 years of age with a hip fracture and COVID-19 who underwent surgical treatment in New York City during the COVID-19 outbreak from March 1, 2020 to May 22, 2020. Clinical characteristics and early postoperative outcomes were reported.

Results: Eight out of the 10 COVID-positive hip fracture patients in our series were asymptomatic on admission with no clinical signs or symptoms of COVID-19 infection. Only 2 patients presented with hypoxia. All 10 patients underwent surgery within 2 days of admission. Five out of the 10 patients - including the patients who presented with hypoxia - subsequently required supplemental oxygen postoperatively. Two patients had persistently elevated oxygen demands requiring prolonged administration of supplemental oxygen therapy beyond postoperative day 3. None of the patients were put on mechanical ventilation. One patient had a presumed venous thromboembolism postoperatively and subsequently died on postoperative day 19, likely due to respiratory failure. There were no other deaths in the early postoperative period. The average length of inpatient stay was 7.8 days.

Conclusions: Our findings suggest that hip fracture patients who present with asymptomatic or mild COVID-19 infection may have temporarily increased oxygen demands postoperatively, but they can safely undergo early surgical intervention after appropriate medical optimization.
