Mortalidad y recurrencia de la enfermedad tromboembólica venosa en pacientes adultos: cohorte prospectiva

INTRODUCCIÓN: La enfermedad tromboembólica venosa (ETV) es una patología que aumenta con la edad. Objetivo: comparar la sobrevida de los ancianos y los jóvenes con un primer episodio de ETV aguda y sintomática. MATERIALES Y MÉTODOS: Cohorte prospectiva de casos incidentes de ETV incluidos en el Registro Institucional de Enfermedad Tromboembólica venosa (NCT01372514) del Hospital Italiano de Buenos Aires entre 2012-2014, dividido en grupos jóvenes (17-64 años) y ancianos (≥ 65 años). Todos los pacientes fueron seguidos anualmente para evaluar el tiempo a la recurrencia (progresión o nuevo evento sintomático de ETV) como eventos competitivos en contexto de muerte y sangrado mayor. Se presentaron los riesgos crudos (c) y ajustados (a). RESULTADOS: se incluyeron 446 pacientes, el 63% (292) fueron mayores de 65 años. La sobrevida fue menor en los ancianos comparados con los jóvenes (p 0.007), a los 3 meses 87% vs 95% y al año 73% vs 87%, respectivamente. Los ancianos presentaron un HRc1,71 y HR a 1.68. La recurrencia global fue 5% (IC 95% 3-8) al mes, 6% (IC 95% 4-9) a los 3 meses, 8% (IC 95% 6-11) al año y 13% (IC 95% 9-18) a los dos años. No se encontró asociación entre la edad y la recurrencia sub hazard 0.8(IC 0,34-1,86). El sangrado ocurrió en un 9% (39) de los pacientes. CONCLUSIONES: La mortalidad global en pacientes con ETV confirmada es mayor en la población anciana. No hubo diferencias en relación a la recurrencia de ETV, ni el sangrado y tampoco con la edad.INTRODUCTION: Venous thromboembolic disease (VTE) is a pathology that increases with age. OBJECTIVE: to compare the survival of the elderly and the young with a first episode of acute and symptomatic VTE. MATERIALS AND METHODS: Prospective cohort of incident VTE cases included in the Institutional Registry of Venous Thromboembolic Disease (NCT01372514) of the Italian Hospital of Buenos Aires between 2012-2014, divided into young groups (17-64 years old) and elderly (65 years old). All the patients were followed annually to assess the time to recurrence (progression or new symptomatic event of VTE) as competitive events in the context of death and major bleeding. Raw (c) and adjusted (a) risks were presented. RESULTS: 446 patients were included, 63% (292) were older than 65 years. Survival was lower in the elderly compared to the young (p 0.007), at 3 months 87% vs. 95% and at one year 73% vs. 87%, respectively. The elderly had a HRc1.71 and HR at 1.68. The overall recurrence was 5% (95% CI 3-8) at one month, 6% (95% CI 4-9) at 3 months, 8% (95% CI). 6-11) at one year and 13% (95% CI 9-18) at two years. No association was found between age and recurrence sub hazard 0.8 (CI 0.34- 1.86). Bleeding occurred in 9% (39) of the patients. CONCLUSIONS: The overall mortality in patients with confirmed VTE is higher in the elderly population. There were no differences in relation to the recurrence of VTE, or bleeding, and neither with age.INTRODUÇÃO: A doença tromboembólica venosa (TEV) é uma patologia que aumenta com a idade.

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

Artrodesis mediocarpiana: Estudio de la evolución clínico radiológica con 3 años de seguimiento mínimo. [Midcarpal fusion: clinical and radiological study on outcomes with a minimum follow-up of three years.]

Objetivo: Determinar la evolución clínica y radiológica de los pacientes tratados con artrodesis mediocarpiana con un seguimiento mínimo de 3 años. Material y métodos: Se estudiaron los pacientes tratados en nuestro servicio mediante artrodesis mediocarpiana desde mayo de 1998. De un total de 27 se incluyeron 11 muñecas que contaban con un seguimiento mínimo de 3 años. Ocho fueron hombre y tres mujeres; la edad media fue 47 años (16 a 66) y el seguimiento promedio 6,7 años (3 a 15). La técnica utilizada fue artrodesis de 2 o 4 esquinas con resección del escafoides más injerto de radio distal. Se los evaluó clínicamente valorando dolor mediante Escala Visual Análoga (EVA), movilidad, y fuerza de puño. Se les realizó QuickDASH y radiografías de control. Resultados: El dolor mejoró de 5/10 en reposo y 8/10 en actividad preoperatorios a 0/10 y 2/10 respectivamente. La movilidad que perdieron los pacientes con respecto al lado sano fue 39% de flexoextensión, 15% de desviación radial y 31% de desviación cubital. No hubo cambios en la pronosupinación y el QuickDASH postoperatorio fue de 10. La fuerza fue del 92% comparado con el lado contralateral. Radiológicamente 4 pacientes no presentaron cambios en la luz articular radiolunar; en los restantes hubo una disminución de la misma. Dos pacientes fueron reoperados por pseudoartrosis con injerto óseo. Conclusiones: La artrodesis mediocarpiana mejora los síntomas, conservando el 61% de la flexoextensión, 85% de la desviación radial, 31% de la cubital y 92% de la fuerza. Nivel de Evidencia: IV

Metaphyseal bone decompression of distal radius for early stages of Kienbock's disease. Minimum follow-up of 10 years.

Background The purpose of this study is to analyze the long-term clinical and radiological results of a series of patients with early stages of the Kienbock disease treated with radius core decompression. Methods This retrospective study included 23 patients with Kienböck’s disease (Lichtman stage II and IIIA) who underwent distal radius metaphyseal core decompression that were followed-up for at least 10 years. At the last follow-up, the patients were evaluated for wrist range of motion and grip strength. The overall results were evaluated by the modified Mayo wrist score and visual analogue scale pain score. We also compared the radiological changes between the preoperative and final follow-up in their Lichtman classification and the modified carpal height ratio. Results The mean follow-up period was 13 years (range 10-18). Based on the modified Mayo Wrist Score, clinical results were excellent in 9 patients, good in 11 patients, fair in 2 and poor in one patient. The mean preoperative pain according to VAS was 7 (range 6-10) and was 1.1 (range 0-6) at the final follow-up. Compared with the opposite side, the average flexion/extension arc was 78% and the grip strength was 81%. Radiographic disease progression according to the Lichtman classification occurred in four wrists. Conclusion This long-term follow-up study shows that radius core decompression is a valid alternative for the treatment of the early stages of the kienbock disease

Surgeons' perspectives on artificial intelligence to support clinical decision-making in trauma and emergency contexts: results from an international survey

Background: Artificial intelligence (AI) is gaining traction in medicine and surgery. AI-based applications can offer tools to examine high-volume data to inform predictive analytics that supports complex decision-making processes. Time-sensitive trauma and emergency contexts are often challenging. The study aims to investigate trauma and emergency surgeons' knowledge and perception of using AI-based tools in clinical decision-making processes. Methods: An online survey grounded on literature regarding AI-enabled surgical decision-making aids was created by a multidisciplinary committee and endorsed by the World Society of Emergency Surgery (WSES). The survey was advertised to 917 WSES members through the society's website and Twitter profile. Results: 650 surgeons from 71 countries in five continents participated in the survey. Results depict the presence of technology enthusiasts and skeptics and surgeons' preference toward more classical decision-making aids like clinical guidelines, traditional training, and the support of their multidisciplinary colleagues. A lack of knowledge about several AI-related aspects emerges and is associated with mistrust. Discussion: The trauma and emergency surgical community is divided into those who firmly believe in the potential of AI and those who do not understand or trust AI-enabled surgical decision-making aids. Academic societies and surgical training programs should promote a foundational, working knowledge of clinical AI

Time for a paradigm shift in shared decision-making in trauma and emergency surgery? Results from an international survey

Background Shared decision-making (SDM) between clinicians and patients is one of the pillars of the modern patient-centric philosophy of care. This study aims to explore SDM in the discipline of trauma and emergency surgery, investigating its interpretation as well as the barriers and facilitators for its implementation among surgeons. Methods Grounding on the literature on the topics of the understanding, barriers, and facilitators of SDM in trauma and emergency surgery, a survey was created by a multidisciplinary committee and endorsed by the World Society of Emergency Surgery (WSES). The survey was sent to all 917 WSES members, advertised through the society’s website, and shared on the society’s Twitter profile. Results A total of 650 trauma and emergency surgeons from 71 countries in five continents participated in the initiative. Less than half of the surgeons understood SDM, and 30% still saw the value in exclusively engaging multidisciplinary provider teams without involving the patient. Several barriers to effectively partnering with the patient in the decision-making process were identified, such as the lack of time and the need to concentrate on making medical teams work smoothly. Discussion Our investigation underlines how only a minority of trauma and emergency surgeons understand SDM, and perhaps, the value of SDM is not fully accepted in trauma and emergency situations. The inclusion of SDM practices in clinical guidelines may represent the most feasible and advocated solutions

Effects of pre-operative isolation on postoperative pulmonary complications after elective surgery: an international prospective cohort study an international prospective cohort study

We aimed to determine the impact of pre-operative isolation on postoperative pulmonary complications after elective surgery during the global SARS-CoV-2 pandemic. We performed an international prospective cohort study including patients undergoing elective surgery in October 2020. Isolation was defined as the period before surgery during which patients did not leave their house or receive visitors from outside their household. The primary outcome was postoperative pulmonary complications, adjusted in multivariable models for measured confounders. Pre-defined sub-group analyses were performed for the primary outcome. A total of 96,454 patients from 114 countries were included and overall, 26,948 (27.9%) patients isolated before surgery. Postoperative pulmonary complications were recorded in 1947 (2.0%) patients of which 227 (11.7%) were associated with SARS-CoV-2 infection. Patients who isolated pre-operatively were older, had more respiratory comorbidities and were more commonly from areas of high SARS-CoV-2 incidence and high-income countries. Although the overall rates of postoperative pulmonary complications were similar in those that isolated and those that did not (2.1% vs 2.0%, respectively), isolation was associated with higher rates of postoperative pulmonary complications after adjustment (adjusted OR 1.20, 95%CI 1.05–1.36, p = 0.005). Sensitivity analyses revealed no further differences when patients were categorised by: pre-operative testing; use of COVID-19-free pathways; or community SARS-CoV-2 prevalence. The rate of postoperative pulmonary complications increased with periods of isolation longer than 3 days, with an OR (95%CI) at 4–7 days or ≥ 8 days of 1.25 (1.04–1.48), p = 0.015 and 1.31 (1.11–1.55), p = 0.001, respectively. Isolation before elective surgery might be associated with a small but clinically important increased risk of postoperative pulmonary complications. Longer periods of isolation showed no reduction in the risk of postoperative pulmonary complications. These findings have significant implications for global provision of elective surgical care.
