Background Healthcare cannot achieve net-zero carbon without addressing operating theatres. The aim of this study was to prioritize feasible interventions to reduce the environmental impact of operating theatres. Methods This study adopted a four-phase Delphi consensus co-prioritization methodology. In phase 1, a systematic review of published interventions and global consultation of perioperative healthcare professionals were used to longlist interventions. In phase 2, iterative thematic analysis consolidated comparable interventions into a shortlist. In phase 3, the shortlist was co-prioritized based on patient and clinician views on acceptability, feasibility, and safety. In phase 4, ranked lists of interventions were presented by their relevance to high-income countries and low–middle-income countries. Results In phase 1, 43 interventions were identified, which had low uptake in practice according to 3042 professionals globally. In phase 2, a shortlist of 15 intervention domains was generated. In phase 3, interventions were deemed acceptable for more than 90 per cent of patients except for reducing general anaesthesia (84 per cent) and re-sterilization of ‘single-use’ consumables (86 per cent). In phase 4, the top three shortlisted interventions for high-income countries were: introducing recycling; reducing use of anaesthetic gases; and appropriate clinical waste processing. In phase 4, the top three shortlisted interventions for low–middle-income countries were: introducing reusable surgical devices; reducing use of consumables; and reducing the use of general anaesthesia. Conclusion This is a step toward environmentally sustainable operating environments with actionable interventions applicable to both high– and low–middle–income countries.

Introduction Neck-shaft angle (NSA) is of paramount importance to orthopedic surgeons due to its implications for various pathologies of the hip and femur. The primary aim of the study was to establish if NSA measurement may be affected by imaging position (standing and supine) and provide evidence regarding whether the contralateral NSA can be used as a template. The secondary aim was to determine a reference value and precisely understand the effects of sex on NSA measurement. Materials and methods We measured bilateral NSA in a retrospective study of 200 standing and 200 supine anteroposterior pelvis radiographs that met the inclusion criteria, while paying special attention to bilateral hip symmetry. The overall inter-rater reliability was 0.688 (CI 0.128–0.851). Matching was performed according to sex (exact matching) and age. Paired t-test, Pearson correlation coefficient, and independent sample t-test were used (p < 0.01). Results A total of 400 pairs of femoral necks were reviewed, comprising of 200 males and 200 females. In the upright radiograph, the overall mean NSA was 131.21° ± 4.72°. There was no significant difference between right and left femur NSA among the patients (p = 0.95). On both sides, male NSA was higher than female NSA (p < 0.001). In supine radiograph, the overall mean NSA for the supine position was 133.06° ± 5.71°. There was a significant difference between NSA of the right and left femur among the patients in the supine position (p < 0.001). On supine radiographs there was no statistically significant difference between male and female NSA (p = 0.85). Conclusion Our findings indicated no significant variability in upright radiographs between the right and left NSA. In contrast, significant asymmetry between the right and left NSA was found in the supine radiographs. However, this study does not provide definitive clinical evidence, and further clinical-oriented research is required. Level of evidence Level III; retrospective comparative study.

Background: The coronavirus disease 2019 (COVID-19) pandemic has negatively impacted public health systems worldwide and created anxiety and stress among communities, resulting in the stigmatization of patients infected with the virus. Stigmatization of individuals who are sick or thought to be infected has a long history and can lead to discrimination and prejudice. This study aims to evaluate the prevalence of COVID-19-related stigma in Jordan, assess the relationship between stigma and the quality of life (QoL) in healthcare workers, and identify possible measures to decrease stressful events. Understanding the psychological effects of healthcare workers' jobs and reducing their burden is essential to improving medical outcomes and the QoL of patients.Methodology: This cross-sectional study was conducted in three primary hospitals in Amman, Jordan, from July to December 2021. Healthcare workers were recruited through convenience sampling and completed a self-administered questionnaire, which included demographic information, a validated COVID-19 stigma questionnaire, work conditions during the pandemic, the Depression, Anxiety and Stress Scale -21 Items (DASS-21) questionnaire to measure depression, anxiety, and stress, and the EUROHIS-QOL questionnaire to assess the QoL. Data were analyzed using descriptive and inferential statistics, including chi-square tests and post hoc analysis. The study was approved by the institutional review board, and participation was voluntary and confidential.Results: The study was conducted among 683 healthcare workers in Jordan, with 77.7% based in the capital city, Amman. Most of the participants were between 18 and 30 years of age, and slightly more than half were female. The study found that 38.1% of healthcare workers would not take the COVID-19 vaccine once it became available. More than half (56%) reported experiencing stress, 61% reported anxiety, and 65% reported depression during the pandemic. Internal medicine specialties and frontline nurses reported the highest levels of stress, and healthcare workers with greater exposure to COVID-19 patients reported higher levels of anxiety and stress. Only 3% of participants reported experiencing stigmatization (p=0.043), with low-income participants reporting it more frequently. Stigmatization was significantly correlated with feelings of depression, anxiety, and stress (p<0.001).Conclusion: Healthcare workers' mental well-being has been affected negatively by the COVID-19 pandemic, resulting in depression, anxiety, and stress. Widespread mental surveillance for healthcare workers is crucial to protect healthcare workers from psychological issues and to improve the healthcare service provided to patients. Stigma among healthcare workers can be a major factor that may increase depression, anxiety, and stress.
