Identifying Preoperative Predictors for 24-Hour Discharge After Elective Hip and Knee Arthroplasties.

Introduction The resumption of elective medical services post-pandemic has brought to the forefront the importance of outpatient arthroplasty services in promoting efficiency and mitigating hospital-acquired infections. This study aimed to identify preoperative factors that predict the success of outpatient lower limb arthroplasty surgeries. Methods Our investigation involved a retrospective review of 606 patients who underwent elective hip and knee arthroplasty. We documented variables such as the hospital length of stay, patient demographics (age and gender), Oxford Joint Scores, body mass index, socioeconomic status, American Society of Anaesthesiologists' (ASA) physical status classification, comorbid conditions, the Functional Comorbidity Index (FCI), preoperative blood test results, implant types, scheduling details of the surgery, and rates of readmission within 30 days post-surgery. A two-step analysis using univariate and multivariate regression models was performed to pinpoint preoperative indicators that could predict same-day discharge following arthroplasty. Results Forty-five patients (7.4%) were discharged within 24 hours of surgery. Early discharge did not correlate with higher rates of readmission within 30 days (p>0.05). Neither weekend nor afternoon surgeries significantly extended the length of stay beyond 24 hours (p>0.05). No significant differences in the prevalence of comorbidities, FCI scores, socioeconomic status, or preoperative blood test results were found when comparing patients discharged within 24 hours to those who stayed longer. Multivariate analysis revealed that patients younger than 65 years (relative risk (RR) 2.41; 95% confidence interval (CI) 1.02-5.74) and those receiving partial knee arthroplasty (RR 8.91; 95% CI 3.05-26.04) were more likely to be discharged within 24 hours. Conclusions Outpatient arthroplasty is a viable option, especially for individuals younger than 65 years undergoing partial knee arthroplasty, independent of other patient-related factors, comorbidities, and specifics of the hospital episode.

Impact of COVID-19 Pandemic on Trauma Theatre Efficiency.

Introduction A large transformation in the management of trauma has ensued following the COVID-19 (coronavirus disease 2019) pandemic. There has been an increase in reliance on guidance for decision-making and alterations in the working of the trauma theatre. This has largely been due to the safety measures implemented. Theatre efficiency has gained increasing importance over the years, and with the added pressure of the pandemic, it is essential that trauma theatres operate efficiently. There has been no data analysing the efficiency of trauma theatre during this pandemic. Methods and Results We retrospectively analyzed the data at our hospital and looked into the parameters to assess trauma theatre efficiency. It was noted that the operative time and anaesthetic time went up significantly in 2020 in comparison to 2019. Also, the change over time and the late start time was significantly high in 2020. A large proportion of cases did not start on time in 2020. This resulted in a decrease in the efficiency of theatre usage. Discussion Reduced productivity of the trauma theatre has been due to several reasons, many of which include implementation of safety measures, such as personal protective equipment (PPE), theatre cleaning, recovery of patients, using designated routes for transfer, and many others. The challenge lies in applying these new measures into our daily practice at the same time while providing efficient care. Conclusion Our study highlights the key areas of concern and improvement which need to be addressed in order to render effective trauma care.

The incidence of venous thromboembolism in total joint replacement during COVID-19 pandemic: has lockdown had an influence?

AIMS: As the first wave of the COVID-19 pandemic began to dip, restarting elective orthopaedics became a challenge. Protocols including surgery at 'green' sites, self-isolation for 14 days, and COVID-19 testing were developed to minimize the risk of transmission. In this study, we look at risk effects of 14-day self-isolation on the incidence of venous thromboembolism (VTE) in our green site hospital among patients undergoing total joint replacement (TJR). METHODS: This retrospective cohort study included 50 patients who underwent TJR. Basic demographic data was collected including, age, sex, American Society of Anesthesiologists (ASA) grade, body mass index (BMI), type of surgery, and complications at two and four weeks. Univariate and multivariate analysis were used to identify risk factors associated with an increased risk of VTE. RESULTS: A total of 50 patients were included in our study, with 24 males and 26 females. The mean age was 67.86 (SD 11.803). Overall, 8% of patients suffered a VTE complication; symptomatic non-fatal pulmoary embolism was confirmed in 6% of patients (n = 3) as an inpatient, and symptomatic deep vein thrombosis was diagnosed in 2% of patients (n = 1) within two weeks of their operation. All patients were found to be female (p < 0.001), had a BMI > 30 (p = 0.317), and were immobile prior to their operation using walking aids (p = 0.016). CONCLUSION: The incidence we report is much higher than the reported incidence in the literature, which we believe is related to the 14-day self-isolation period and immobility prior to their operation. We recommend that all patients undergoing TJR that require a period of self-isolation, are pre-assessed prior to self-isolation for their risk of VTE, potentially using mechanical and chemical prophylaxis to reduce the likelihood of developing VTE.Cite this article: Bone Jt Open 2020;1-12:751-756.
