Purpose:The COVID-19 pandemic has caused 1.4 million deaths globally and is associated with a 3-4 times increase in 30-day mortality after a fragility hip fracture with concurrent COVID-19 ***,death from COVID-19 infection occurs between 15 and 22 days after the onset of symptoms,but this period can extend up to 8 *** study aimed to assess the impact of concurrent COVID-19 infection on 120-day mortality after a fragility hip ***:A multi-centre prospective study across 10 hospitals treating 8%of the annual burden of hip fractures in England between 1st March and 30th April,2020 was *** whose surgical treatment was payable through the National Health Service Best Practice Tariff mechanism for"fragility hip fractures"were included in the ***'120-day mortality was assessed relative to their perioperative COVID-19 *** analysis was performed using SPSS version ***:A total of 746 patients were included in this study,of which 87(11.7%)were COVID-19 *** rates at 30-and 120-day were significantly higher for COVID-19 positive patients relative to COVID-19 negative patients(p<0.001).However,mortality rates between 31 and 120-day were not significantly different(p=0.107),16.1%and 9.4%respectively for COVID-19 positive and negative patients,odds ratio 1.855(95%CI 0.865-3.978).Conclusion:Hip fracture patients with concurrent COVID-19 infection,provided that they are alive at day-31 after injury,have no significant difference in 120-day *** the growing awareness and concern of "long-COVID"and its widespread prevalence,this does not appear to increase mediumterm mortality rates after a hip fracture.
