Carbon footprinting and environmental impact of gastrointestinal endoscopy procedures at a tertiary care institution: a prospective multi-dimensional assessment

BACKGROUND

Given the imperative to combat climate change, reducing the healthcare sector's implications on the environment is crucial.

OBJECTIVE

This study aims to offer a comprehensive assessment of the environmental impact of gastrointestinal endoscopy (GIE) procedures, specifically focusing on greenhouse gas (GHG) emissions and waste generation.

DESIGN

A prospective study was conducted at the Asian Institute of Gastroenterology (AIG Hospitals), Hyderabad, India, from 29 May to 10 June 2023, including all consecutive GIE procedures. Carbon emissions for various variables involved were calculated with specific emission factors using 'The GHG Protocol'.

RESULTS

Based on data from 3244 consecutive patients undergoing 3873 procedures, the study revealed a total carbon footprint of 148 947.32 kg CO2e or 38.45 kg CO2e per procedure. Excluding patient travel, the emissions were 6.50 kg CO2e per procedure. The total waste generated was 1952.50 kg, averaging 0.504 kg per procedure, far less than 2-3 kg per procedure in the West. The waste disposal breakdown was 9.5% direct landfilling, 64.8% incineration, then landfilling and 25.7% recycling, which saved 380 kg CO2e. India effectively recycles 25.7% of hospital-related waste, which undergoes landfilling in the West. The primary contributors to GHG emissions were patient travel (83.09%), electricity consumption (10.42%), medical gas transport and usage (3.63%) and water consumption (1.86%). Diagnostic procedures generate less waste and lower carbon footprint than therapeutic procedures.

CONCLUSION

This study highlights the significant environmental footprint of GIE procedures, emphasising the importance of optimising practices to reduce patient travel and repeat procedures, alongside improving electricity and water management for sustainable healthcare.

Advanced trainee perceptions of disposable duodenoscopes and disposable endcaps: results of a nationwide survey

INTRODUCTION

Disposable duodenoscopes and duodenoscopes with disposable endcaps are being used in clinical practice to reduce or eliminate the risk of transmitting infections. The study aim was to assess perceptions and experiences regarding the use of these duodenoscopes among advanced endoscopy fellows in a nationally representative sample.

METHODS

A 17-item electronic survey was sent to 74 advanced endoscopy training programs. The survey was completed by 50 participants and their responses were included for analysis.

RESULTS

Most participants were from academic training programs (82.7%) and identified as being in their 7th year of post graduate training (92%; PGY-7). Participants performed an average of 414 ERCPs. 29% reported difficulty with cannulation using disposable duodenoscopes versus 15.7% with duodenoscopes with disposable endcaps (vs. standard duodenoscope). 96% of trainees perceived disposable duodenoscopes as not cost effective and 92% stated they would not use this device during independent practice. 100% of trainees stated that they would use duodenoscopes with disposable endcaps during independent practice. For their most challenging cases, 90% of trainees preferred using standard reprocessable duodenoscopes while no trainee indicated they would prefer using a disposable duodenoscope in this scenario. 82% of participants stated that disposable duodenoscopes and disposable endcaps should be used exclusively or preferentially for high-risk patients citing cost, functionality, and concerns regarding environmental impact.

DISCUSSION

Advanced endoscopy fellows perceive disposable duodenoscopes as impacting technical maneuverability. Concerns about functionality, cost effectiveness and environmental impact are barriers to adoption.

The 2022 top 10 list of endoscopy topics in medical publishing: an annual review by the American Society for Gastrointestinal Endoscopy Editorial Board

Using a systematic literature search of original articles published during 2022 in Gastrointestinal Endoscopy and other high-impact medical and gastroenterology journals, the 10-member Editorial Board of the American Society for Gastrointestinal Endoscopy composed a list of the 10 most significant topic areas in GI endoscopy during the study year. Each Editorial Board member was directed to consider 3 criteria in generating candidate lists-significance, novelty, and global impact on clinical practice-and subject matter consensus was facilitated by the Chair through electronic voting. The 10 identified areas collectively represent advances in the following endoscopic spheres: artificial intelligence, endoscopic submucosal dissection, Barrett's esophagus, interventional EUS, endoscopic resection techniques, pancreaticobiliary endoscopy, management of acute pancreatitis, endoscopic environmental sustainability, the NordICC trial, and spiral enteroscopy. Each board member was assigned a consensus topic area around which to summarize relevant important articles, thereby generating this précis of the "top 10" endoscopic advances of 2022.
