Background

General anaesthesia is in common use for patients undergoing surgical procedures, with the option of both inhalational and intravenous anaesthetic techniques. Anaesthetic gases are often excluded from discussions on sustainable healthcare delivery, despite being a significant contributor to the overall environmental impact of healthcare services.

Methods

A literature review was carried out on previously published papers on the impact anaesthetic gases have on our environment and at ways to reduce their impact in current anaesthetic practice. The aim was to write a narrative review detailing the areas of concern as well as the current clinical situation in the European setting.

Summary/conclusions

The two classes of inhaled anaesthetic agent most frequently used are nitrous oxide and volatile agents (most commonly sevoflurane, isoflurane and desflurane). Both are recognised greenhouse gases that contribute to climate change.

Minor modifications in the use of anaesthetic gases can have a significant environmental impact. These modifications include avoiding nitrous oxide whenever possible, avoiding desflurane (and using sevoflurane instead), using low flow anaesthesia during maintenance, swapping volatile-based anaesthesia for a TIVA technique when clinically appropriate and considering the use of central neuraxial or regional anaesthesia in place of general anaesthesia when possible.

The environmental impact of healthcare is an issue currently examined with increased scrutiny and on a global scale with multiple stakeholders seeking to identify the appropriate interventions to reduce it. Interestingly, a significant portion of healthcare's environmental impact stems from intensive modalities of treatment for chronic disease. There is no better example than End-Stage Renal Disease (ESRD), where dialysis or transplantation are the modalities of treatment offered to the vast majority of these patients. Kidney transplantation (KTx) offers a longer life expectancy and improved quality of life in comparison to dialysis. Cost-effectiveness analyses have proven its financial superiority, as well. PubMed and EMBASE literature search using keywords “kidney transplantation”, “carbon footprint”, “sustainability” showed that there is no published work in the field of environmental sustainability in kidney transplantation. Relevant literature was identified for surgical services and applied to transplantation. Assuming its environmental superiority to dialysis, maximising KTx rate would be an important action towards “green” renal care services. That could be achieved through living organ donation, systematic use of machine perfusion for extended criteria deceased donors and individualised immune risk stratification techniques. All these measures aim towards implementing enhanced recovery protocols and two vital steps can be taken towards assessing their value. The first step is a detailed audit of the environmental impact of these novel techniques and secondly their impact in reducing the length of hospital stay and its subsequent environmental impact. Another key element is delivering appropriate post-operative care, substituting allograft biopsy with non-invasive techniques and reducing physical outpatient follow-up, using telemedicine. The gap in quantifying KTx services environmental impact needs to be addressed urgently, with development of strategies within the multidisciplinary transplant team. Introducing novel technologies can lead to donor pool expansion and improved organ utilisation rates, transforming transplant services in “green” hubs.

Introduction

Healthcare contributes significantly to carbon dioxide emissions, which can be reduced by promoting sustainable mobility amongst staff commuting. This study aims to investigate the national sustainable transport infrastructure for staff of healthcare facilities and utilise this data to develop a novel scoring and ranking system.

Methods

This was an empirical retrospective observational study. Data was collected on all 47 hospitals sustainable transport infrastructure. A working group calculated the weighted scores for each sustainable transport data point. These scores were used to calculate the Total and Active Sustainability Scores for each hospital, allowing a ranking to be formed.

Results

7 of 47 (15 %) hospitals had EV charging on campus. 17 of 47 (36 %) hospitals had secure bike parking. 2 of 47 (4 %) hospitals had a “bike hub”. 18 of 47 (38 %) hospitals had a bike lane. 13 of 22 (59 %) city hospitals had bike sharing facilities. 42 of 47 (89 %) hospitals had one public transport route. City hospitals ranked higher in both Total & Active Sustainability Scores.

Discussion

This study explored a new concept of measuring sustainable transport infrastructure. Frameworks examining sustainability are available, however, none allowed for ranking of hospitals. This study highlights the lack of both research in this field and sustainable transport infrastructure in hospitals.

Objectives

Cardiothoracic surgery has reported poor equality, diversity, and inclusion amongst its faculty [1–3]. We explored how gender, ethnicity, and disability influence medical students’ interest in cardiothoracic surgery as a career choice, as well as overall exposure to cardiothoracic surgery in the undergraduate curriculum.

Methods

We distributed a 26-item Google Forms online survey to student members of a medical education group from all 37 UK medical schools via social media. Respondents were asked to rank different ‘factors of interest’ on a 1–5 Likert scale (1 ​= ​not important at all, 5 ​= ​very important) and were encouraged to add free-text comments. Quantitative data were analysed using SPSS.

Results

There were 258 respondents, 62% identifying as female and 38% male. Respondents' ethnicities were 45% White, 44% Asian or Asian British, and 11% from other ethnic groups. 11% of respondents confirmed ‘long-standing illness or disability’.

Men were almost twice as likely to consider a career in cardiothoracic surgery than women (33% vs 19%; p ​< ​0.001). Women were more likely than men to feel that their gender, lack of a similarly gendered mentor, and long working hours were important factors when considering cardiothoracic surgery as a career.

Ethnicity of the respondent did not appear to affect how they perceived the challenges of a career in cardiothoracic surgery. Interestingly, ‘long-standing illness or disability’ did not significantly affect the decision making to consider this specialty as a career.

Overall, 73% of respondents reported not having adequate exposure to cardiothoracic surgery at medical school and agreed they would benefit from more time.

Conclusions

Female medical students felt their gender, lack of same-sex role models, and perceived long working hours were barriers in considering cardiothoracic surgery as a career. All students felt the need for more exposure to Cardiothoracic Surgery in the undergraduate curriculum.

Background

Patient blood management recommends the use of intravenous (IV) iron infusion to reduce inappropriate blood transfusion perioperatively for anaemic surgical patients. However, evidence regarding its use in urgent femoral fracture surgery is limited. This systematic review aims to collate the current evidence regarding the utilisation of IV iron in femoral fracture surgery.

Method

MEDLINE, Embase, Cochrane CENTRAL, Clinicaltrials.gov, and the WHO ICTRP databases were systematically searched for randomised controlled trials (RCT) comparing the outcomes of perioperative IV iron infusion with placebo in adults requiring surgical management for femoral fractures. Risk ratios (RR) were calculated using the Mantel-Haenszel method for dichotomous outcomes, and mean differences (MD) were calculated with the inverse-variance method for continuous outcomes.

Results

Six RCTs with 1292 patients were included. No statistically significant difference was found in the proportion of patients receiving red blood cell (RBC) transfusion (RR = 0.87, 95%CI: 0.75; 1.01, p = 0.058) between groups. Statistically significant difference in postoperative haemoglobin concentration was found between groups measured between day 4–7 of admission (MD = 1.93 g/L, 95%CI: 0.48; 3.39, p = 0.024), but not clinically significant. No statistically significant differences were found between groups in mortality rate, length of hospital stay, infection rate, or return to home rate.

Conclusion

Current evidence indicates that IV iron infusion alone does not provide any clinically significant benefit in femoral fracture surgery. Further high-quality RCTs are needed to explore its synergistic potential when used in combination with other perioperative optimisation methods, including tranexamic acid, erythropoietin and cell salvage.
