Reducing the environmental impact of surgery on a global scale: systematic review and co-prioritization with healthcare workers in 132 countries

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

Ovarian status in healthy postmenopausal women: follow-up 12 months after transvaginal ultrasound

OBJECTIVE: We have previously reported on the point prevalence of ovarian lesions detected by transvaginal ultrasound (TVU) in 515 asymptomatic women at least 5 years postmenopause. The aims of this study were to report, in the same women, on the repeatability of visualization of the ovaries (TVU) and the natural history of ovarian lesions seen at baseline but not treated surgically and to assess whether any women developed new ovarian abnormalities 12 months later. METHODS: The study involved a cohort of 515 postmenopausal women recruited from the community, at least 5 years past their last period. They were assessed at baseline and again after 12 months with TVU and serum levels of inhibin and CA-125. RESULTS: The right and left ovaries were seen on both occasions in 80% and 68% of women, respectively. Of the 49 women who had an ovarian lesion at baseline, did not undergo surgery at that time, and had a follow-up TVU, the lesion was unchanged 12 months later in 30 women. Four women developed a new ovarian lesion within the 12 months. None of the 14 women who underwent surgery on the basis of the ovarian appearance at baseline, or the 2 who had surgery on the basis of the ovarian appearance at follow-up, had an ovarian malignancy. CONCLUSIONS: The use of TVU in women at least 5 years after menopause is problematic because the ovaries cannot be visualized in all women and because TVU has the potential to identify many benign lesions that would otherwise remain undetected. These are important considerations in weighing up the risks and benefits of using TVU as a screening tool.Robin J. Bell, David L. Healy, David M. Robertson, Tom Jobling, Martin K.
