Peri-operative SARS-CoV-2 infection increases postoperative mortality. The aim of this study was to determine the optimal duration of planned delay before surgery in patients who have had SARS-CoV-2 infection. This international, multicentre, prospective cohort study included patients undergoing elective or emergency surgery during October 2020. Surgical patients with pre-operative SARS-CoV-2 infection were compared with those without previous SARS-CoV-2 infection. The primary outcome measure was 30-day postoperative mortality. Logistic regression models were used to calculate adjusted 30-day mortality rates stratified by time from diagnosis of SARS-CoV-2 infection to surgery. Among 140,231 patients (116 countries), 3127 patients (2.2%) had a pre-operative SARS-CoV-2 diagnosis. Adjusted 30-day mortality in patients without SARS-CoV-2 infection was 1.5% (95%CI 1.4-1.5). In patients with a pre-operative SARS-CoV-2 diagnosis, mortality was increased in patients having surgery within 0-2 weeks, 3-4 weeks and 5-6 weeks of the diagnosis (odds ratio (95%CI) 4.1 (3.3-4.8), 3.9 (2.6-5.1) and 3.6 (2.0-5.2), respectively). Surgery performed ≥ 7 weeks after SARS-CoV-2 diagnosis was associated with a similar mortality risk to baseline (odds ratio (95%CI) 1.5 (0.9-2.1)). After a ≥ 7 week delay in undertaking surgery following SARS-CoV-2 infection, patients with ongoing symptoms had a higher mortality than patients whose symptoms had resolved or who had been asymptomatic (6.0% (95%CI 3.2-8.7) vs. 2.4% (95%CI 1.4-3.4) vs. 1.3% (95%CI 0.6-2.0), respectively). Where possible, surgery should be delayed for at least 7 weeks following SARS-CoV-2 infection. Patients with ongoing symptoms ≥ 7 weeks from diagnosis may benefit from further delay.

SARS-CoV-2 has been associated with an increased rate of venous thromboembolism in critically ill patients. Since surgical patients are already at higher risk of venous thromboembolism than general populations, this study aimed to determine if patients with peri-operative or prior SARS-CoV-2 were at further increased risk of venous thromboembolism. We conducted a planned sub-study and analysis from an international, multicentre, prospective cohort study of elective and emergency patients undergoing surgery during October 2020. Patients from all surgical specialties were included. The primary outcome measure was venous thromboembolism (pulmonary embolism or deep vein thrombosis) within 30 days of surgery. SARS-CoV-2 diagnosis was defined as peri-operative (7 days before to 30 days after surgery); recent (1-6 weeks before surgery); previous (≥7 weeks before surgery); or none. Information on prophylaxis regimens or pre-operative anti-coagulation for baseline comorbidities was not available. Postoperative venous thromboembolism rate was 0.5% (666/123,591) in patients without SARS-CoV-2; 2.2% (50/2317) in patients with peri-operative SARS-CoV-2; 1.6% (15/953) in patients with recent SARS-CoV-2; and 1.0% (11/1148) in patients with previous SARS-CoV-2. After adjustment for confounding factors, patients with peri-operative (adjusted odds ratio 1.5 (95%CI 1.1-2.0)) and recent SARS-CoV-2 (1.9 (95%CI 1.2-3.3)) remained at higher risk of venous thromboembolism, with a borderline finding in previous SARS-CoV-2 (1.7 (95%CI 0.9-3.0)). Overall, venous thromboembolism was independently associated with 30-day mortality ). In patients with SARS-CoV-2, mortality without venous thromboembolism was 7.4% (319/4342) and with venous thromboembolism was 40.8% (31/76). Patients undergoing surgery with peri-operative or recent SARS-CoV-2 appear to be at increased risk of postoperative venous thromboembolism compared with patients with no history of SARS-CoV-2 infection. Optimal venous thromboembolism prophylaxis and treatment are unknown in this cohort of patients, and these data should be interpreted accordingly.

В период вспышки COVID-19 весь мир, в том числе Казахстан был ориентирован на оказание экстренной помощи пациентам с коронавирусной инфекцией. На фоне увеличения нагрузки на систему здравоохранение, в связи с пандемией система здравоохрарнение и экономическое положение РК не справлялась. Система здравоохранения связанный с короновирусом наглядно продемонстрировал необходимость корректировок и переосмысление некторыха спектов вопроса организации стационарной помощи. Цель. Определить направлений совершенствования оказания стационарной помощи взрослому населению в условиях пандемии на примере многопрофильных стационаров г. Алматы. Метод исследования. Обобщение, систематизация и анализ отечественного и зарубежного опыты организации стационарной помощи при пандемии. Выводы. Была предложена оптимизированная и научно обоснованная организационная модель стационарной помощи при пандемии в условиях г. Алматы. Данная модель позволяет качественно и эффективно оказывать стационарную помощь взрослому населению в условиях пандемии на примере многопрофильных стационаров. Resume: During the outbreak of COVID-19, the whole world, including Kazakhstan, was focused on providing emergency care to patients with coronavirus infection. Against the backdrop of an increase in the burden on the healthcare system, due to the pandemic, the healthcare system and the economic situation of the Republic of Kazakhstan could not cope. The health care system associated with the coronavirus has cleary demonstrated the need for adjustments and rethinking some aspects of the issue of organizing hospital care. Aim. The purpose of the article is to identify areas for improving the provision of inpatient care to the adult population in a pandemic using the example of multidisciplinary hospitals in Almaty. Search strategy. The research methods were generalization, systematization and analysis of domestic and foreign experience in organizing hospital care during a pandemic. Result. An optimized and evidence-based organizational model of inpatient care during a pandemic in the conditions of Almaty was proposed. This model makes it possible to provide high-quality and effective inpatient care to the adult population in a pandemic using the example of multidisciplinary hospitals.
