Single centre concept of ‘cold site’ elective surgery during the peak of COVID-19 pandemic: A cohort study

ABSTRACT: Objective The COVID-19 pandemic caused a major strain on healthcare systems across the globe. As these systems got overwhelmed with the emergency care of the infected patients, widespread cancellations of elective surgery occurred. Our hospital utilised local private hospital as a dedicated cold site (CS) for urgent elective surgery during the peak of the COVID-19 pandemic. We aim to analyse the outcomes at this dedicated cold site. Method A retrospective review of a prospectively maintained database of all the cases operated at the CS during a 2-month period (30 March 2020 to 29 May 2020) was carried out. The primary outcome was 30-day COVID-19 related mortality. The secondary outcomes were 30-day non-COVID-19 related mortality, complications, readmission and development of COVID-19 symptoms. Results A total of 153 patients were operated on at the CS over the study period with a median age of 57 years (Interquartile range, IQR 47–70). 62% were females and 82% had a Body Mass Index (BMI) less than 30.73% of the operations were performed for cancer. 59% of the surgeries were graded as intermediate and 26% as major or complex. There was no mortality at 30 days from COVID-19 or non COVID-19 causes. There was only 1 (0.65%) readmission. 7 patients (4.57%) developed complications. 1 (0.65%) patient was diagnosed with COVID-19 in the postoperative period while 3 had COVID-19 symptoms but were tested negative. Conclusion Urgent elective surgery is safe and feasible during the COVID-19 pandemic if a dedicated cold site is available. Highlights • This study reports findings of a dedicated cold site elective surgery during the peak of COVID-19 pandemic.• There was no COVID-19 or nonCOVID-19 related 30-day mortality.• There was only one (0.65%) 30-day readmission and one patient (0.65%) had COVID-19 in the post-operative period.• Dedicated cold site with multi model approach using careful patient selection and appropriate infection control measures including personal protective equipment is safe and feasible.

Project description:IntroductionMore than 30 000 cardiac surgery procedures are performed in the UK each year, however, postoperative complications and long-term failure of interventions are common, leading to repeated surgeries. This represents a significant burden on the patient and health service.Routinely, patients are discharged to their general practitioner 6 weeks postoperatively and research studies typically only report short-term outcomes up to 1 year after surgery, together this makes long-term outcomes of cardiac surgery difficult to monitor. Further, traditional research methods have yet to advance understanding of what causes early complications and why surgical interventions fail.Methods and analysisThis prospective cohort study will characterise participants undergoing cardiac surgery at baseline, describe short-term, medium-term and long-term health outcomes postoperatively and collect tissue samples.All eligible adult patients undergoing cardiac surgery at the Bristol Heart Institute, UK will be approached for consent. Recruitment is expected to continue for up to 10 years resulting in the largest cohort of cardiac patients reported to date. Blood, urine and waste tissue samples will be collected during admission. Samples, along with anonymised data, will be used to investigate outcomes and inform predictive models of complications associated with cardiac surgery.Data about the surgical admission will be obtained from hospital databases and medical notes. Participants may be monitored up to 5 years postoperatively using data obtained from NHS digital. Participants will complete health questionnaires 3 months and 12 months postoperatively.The analysis of data and tissue samples to address specific research questions will require separate research protocols and ethical approval.Ethics and disseminationThis study was approved by the East Midlands Nottingham 2 Research Ethics Committee.Findings will be disseminated through peer-reviewed publications and presentation at national and international meetings. Participants will be informed of results in annual newsletters.Trial registration numberISRCTN90204321.

Project description:PurposeThe preferred neuraxial anesthetic technique for patients with class 3 obesity undergoing elective Cesarean delivery is still under debate. We aimed to describe the anesthetic technique used in our tertiary institution across body mass index (BMI) groups and different surgical incisions.MethodIn this historical cohort study, we reviewed medical records of patients with a BMI ≥ 40 kg·m-2 undergoing elective Cesarean delivery between July 2014 and December 2020. We collected data on patient characteristics, anesthetic and surgical technique, and procedural times. For data analysis, we stratified patients by BMI into three different groups: 40.0-49.9 kg·m-2, 50.0-59.9 kg·m-2, and ≥ 60.0 kg·m-2.ResultsWe included 396 deliveries, distributed as follows: 258 with a BMI 40.0-49.9 kg·m-2, 112 with a BMI 50.0-59.9 kg·m-2, and 26 with a BMI ≥ 60.0 kg·m-2. For patients with a BMI 40.0-49.9 kg·m-2, the anesthetic technique of first choice was predominantly spinal anesthesia (71%), whereas for those with a BMI ≥ 60.0 kg·m-2, spinal anesthesia was never used as the anesthetic of first choice. With regard to the surgical incision, spinal anesthesia was almost exclusively used for patients undergoing Pfannenstiel incision and was rarely used for a higher supra- or infraumbilical transverse or midline incision. The overall incidence of general anesthesia was low (7/396, 1.8%). Anesthetic time, surgical time, and operating room time increased almost twofold in patients with a BMI ≥ 60.0 kg·m-2 compared with those with a BMI of 40.0-49.9 kg·m-2.ConclusionNeuraxial anesthesia was successfully used in approximately 98% of patients with class 3 obesity undergoing elective Cesarean delivery. The choice of regional anesthesia technique varied with increasing BMI and with the planned surgical incision. Procedural times increased with increasing BMI. This information should prove useful for comparing anesthetic choices and outcomes in this challenging population.

Project description:IntroductionThe prevalence of non-alcoholic fatty liver disease (NAFLD) ranges from 25% in the general population to 90% in patients with obesity scheduled for bariatric surgery. NAFLD can progress towards non-alcoholic steatohepatitis (NASH) associated with complications such as cirrhosis, hepatocellular carcinoma and cardiovascular disease. To date, losing weight and lifestyle modifications are the best known treatments for NASH. Bariatric surgery significantly improves NAFLD/NASH in the short term. However, the extent of this improvement is not yet clear and long-term data on the natural course of NAFLD/NASH after bariatric surgery are lacking. The factors involved in NAFLD/NASH regression after bariatric surgery have not been elucidated.Methods and analysisThis is an observational prospective cohort study including patients scheduled for bariatric surgery. Extensive metabolic and cardiovascular analyses will be carried out including measurements of carotid intima media thickness and pulse wave velocity. Genomic, proteomic, lipidomic and metabolomic studies will be done. Microbioma analyses before and 1 year after surgery will be done. Transient elastography measurements will be performed before and at 1, 3 and 5 years after surgery. For those with an elevated preoperative transient elastography measurement by Fibroscan, a laparoscopic liver biopsy will be performed during surgery. Primary outcome measures are the change of steatosis and liver fibrosis 5 years after surgery. Secondary outcome measure is the comparison of the transient elastography measurements with the NAFLD Activity Score from the biopsies.Ethics and disseminationThe protocol has been approved by the Medical Research Ethics Committees United, Nieuwegein, on 1 March 2022 (registration code R21.103/NL79423.100.21). The study results will be submitted for publication in peer-reviewed journals and data will be presented at scientific meetings.Trial registration numberNCT05499949.
