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

Abstract 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

Pulmonary paracoccidoidomycosis: radiology and clinical-epidemiological evaluation Paracoccidioidomicose pulmonar: radiologia e avaliação clínico-epidemiológica

INTRODUCTION: The purpose of this study was to compare respiratory signs and symptoms between patients with and without chest X-ray abnormalities in order to establish the meaning of radiographic findings in pulmonary PCM diagnosis. METHODS: The epidemiological, clinical and radiological lung findings of 44 patients with paracoccidiodomycosis (PCM) were evaluated. Patients were divided into two groups of 23 and 21 individuals according to the presence (group 1) or absence (group 2) of chest X-ray abnormalities, respectively, and their clinical data was analyzed with the aid of statistical tools. RESULTS: As a general rule, patients were rural workers, young adult males and smokers - group 1 and 2, respectively: males (91.3% and 66.7%); mean age (44.4 and 27.9 year-old); smoking (34.7% and 71.4 %); acute/subacute presentation (38.1% and 21.7%); chronic presentation (61.9% and 78.3%). The most frequent respiratory manifestations were - group 1 and 2, respectively: cough (25% and 11.4%) and dyspnea (22.7% and 6.8%). No statistical difference was observed in pulmonary signs and symptoms between patients with or without radiographic abnormalities. The most frequent radiological finding was nodular (23.8%) or nodular-fibrous (19%), bilateral (90.5%) and diffuse infiltrates (85.7%). CONCLUSIONS: Absence of statistical difference in pulmonary signs and symptoms between these two groups of patients with PCM indicates clinical-radiological dissociation. A simplified classification of radiological lung PCM findings is suggested, based on correlation of these data and current literature review.<br>INTRODUÇÃO: Comparar sinais e sintomas respiratórios entre pacientes com e sem alterações à radiografia de tórax para se estabelecer o significado dos achados radiográficos no diagnóstico da paracoccidioidomicose pulmonar. MÉTODOS: Os achados epidemiológicos, clínicos e radiológicos de 44 pacientes com paracoccidioidomicose (PCM) foram avaliados. Os pacientes foram divididos em dois grupos de 23 e 21 indivíduos de acordo com a presença (grupo 1) ou ausência (grupo 2) de anormalidades à radiografia de tórax, respectivamente, e seus dados clínicos foram analisados com auxílio de ferramentas estatísticas. RESULTADOS: Como regra geral, os pacientes eram trabalhadores rurais do sexo masculino, tabagistas e em idade adulta jovem - grupo 1 e 2, respectivamente: homens (91,3% e 66,7%); média de idade (44,4 e 27,9 anos); tabagismo (34,7% e 71,4 %); forma aguda/subaguda (38,1% e 21,7%); forma crônica (61,9% e 78,3%). As manifestações respiratórias mais frequentes foram - grupo 1 e 2, respectivamente: tosse (25% e 11,4%) e dispnéia (22,7% e 6,8%). Nenhuma diferença estatística foi observada nos sinais e sintomas respiratórios entre pacientes com ou sem anormalidades radiográficas. Os achados radiológicos mais frequentes foram o padrão nodular (23,8%) ou nodular-fibrótico (19%), bilateral (90,5%) e infiltrado difuso (85,7%). CONCLUSÕES: A ausência de diferença estatística nos sinais e sintomas pulmonares entre estes dois grupos de pacientes com PCM sugere dissociação clínico-radiológica. Uma classificação simplificada dos achados radiológicos pulmonares da PCM é sugerida, com base na correlação destes dados e revisão da literatura atual
