Influence of perioperative SARS-CoV-2 infection on mortality in orthopaedic inpatients with surgically treated traumatic fractures.

ABSTRACT: SARS-CoV-2 has had an extensive influence on orthopaedic surgery practice and has been associated with an increased risk of mortality. There is limited evidence of how this pertains to acute orthopaedic surgery with inpatient care. A retrospective cohort study on traumatic fracture patients requiring inpatient care between February 25, 2020 and March 25, 2021 was conducted. Patients were grouped by perioperative SARS-CoV-2 infection, defined as a positive SARS-CoV-2 test from 7 days before to 7 days after orthopaedic surgery, and compared using linear regression and Cox proportional hazards model for primary outcome 30-day mortality and secondary outcome hospital length of stay. In total, 5174 adults with a length of stay ≥ 48 h and an orthopaedic procedure due to a registered traumatic fracture were admitted from February 25, 2020 and discharged before March 26, 2021. Among the 5174 patients, 65% (3340/5174) were female, 22% (1146/5174) were 60-74 years and 56% (2897/5174) were 75 years or older. In total, 144 (3%) had a perioperative SARS-CoV-2 infection. Perioperative SARS-CoV-2 infection was associated with an increased 30-day mortality (aOR 4.19 [95% CI 2.67-6.43], p < 0.001). The median (IQR) length of stay after surgery was 13 days (IQR 6-21) for patients with, and 7 days (IQR 2-13) for patients without, perioperative SARS-CoV-2 infection. Perioperative SARS-CoV-2 infection increased 30-day mortality risk and hospital length of stay for traumatic fracture patients requiring inpatient surgical care. Pre- and postoperative infection were both associated with similar increases in mortality risk.

Project description:Introduction:Acetabulum fractures, though relatively uncommon, are associated with significant morbidity and mortality. These involve high energy trauma and due to their complex nature, the management requires understanding the relevant surgical anatomy, defining the injury via appropriate radiographic assessment and determining a suitable treatment plan. Literature is scarce for the demographic data, fracture patterns, associated injuries, management and early complications in the Indian scenario. These factors play a pivotal role in the ultimate recovery of the patients. Therefore this study was conceptualised to assess the epidemiology and evaluate the complications of these fractures. Furthermore the effects of various factors determining the quality of reduction in surgically treated patients were also assessed. Methodology:This was a prospective observational study in which patients presenting to the advance trauma centre of our institute with acetabulum fractures were included. Demographical data of the patients, mechanisms of injuries, fractures morphologies, complications and radiological outcomes were recorded prospectively. Results:116 patients with acetabular fractures were included in the study. 81% of these were males, with average age of 39.95?±?15.87 years; with road traffic accidents being the predominant mode of injuries. Mortality was reported in 5 patients; 4 patients had deep venous thrombosis and sciatic nerve injuries were seen in 12 patients of which 4 were iatrogenic. 8 patients had some form of infection, out of which 4 required multiple debridements. 4 cases developed heterotrophic ossification while 2 cases had loss of reduction. The timing of surgery and other associated fractures had significant effect on the quality of reduction (p?<?0.05); while age, gender, mode of injury or individual fracture patterns had no such effect. Conclusions:Proper radiological assessment and evaluation of fracture configuration is important for management of acetabulum fractures. When indicated, this should be followed by early open reduction and internal fixation to achieve anatomical reduction, with management of associated injuries for better outcomes.

Project description:IntroductionIn older patients with axis fractures, the survival benefit from surgery is unclear due to high baseline mortality. Comparative effectiveness research can provide evidence from population level cohorts. Propensity weighting is the preferred methodology for reducing bias when analyzing national administrative cohort data for these purposes but has not yet been utilized for this important surgical conundrum. We estimate the effect of surgery on mortality after isolated acute traumatic axis fracture in older adults.Materials and methodsWe used a retrospective population-based cohort of Medicare patients and generated a propensity score-weighted nonsurgical cohort and compared mortality with and without surgery. This balanced the comorbid conditions of the treatment groups. Incident fractures were defined using a predetermined algorithm based on enrollment, code timing, and billing location. The primary outcome was adjusted all-cause 1-year mortality.ResultsFrom 12 372 beneficiaries with 1-year continuous enrollment and a coded axis fracture, 2676 patients met final inclusion/exclusion criteria. Estimated incidence was 16.5 per 100 000 person-years overall in 2014 (95% confidence interval [CI]: 15.0-18.0) and was stable from 2008 through 2014. Patients with axis fracture had a mean age of 82.8 years, 30.2% were male, and 91.9% were Caucasian. Mortality was 3.8 times higher (CI 3.6-4.1) compared with the general population of older US adults. Propensity-weighted mortality at 1 year for nonsurgical patients was 26.7 of 100 (CI: 24.5-29.0). Mortality for surgical patients was significantly lower (19.7/100; CI 14.5-25.0). Risk difference was 7.0 fewer surgical deaths per 100 patients (CI: 1.3-12.7). Surgical patients aged 65 to 74 years had the largest difference in mortality with 11.2 fewer deaths per 100 (CI: 1.1-21.3).DiscussionPatients with axis fractures are predominantly older Caucasian women and have a higher mortality rate than the general population. Propensity-weighted mortality at 1-year was lower in the surgical patients with the largest risk difference occurring in patients 65 to 74 years old.ConclusionsSurgery may provide an independent survival benefit in patients aged 65 to 75 years, and the mortality difference diminishes thereafter.
