Reduction Of Carbon Dioxide Utilisation in Endoscopy Procedures

This case study was completed as part of the Frimley Health NHS Foundation Trust Green Ward Competition 2020, by the Endoscopy Team.

Team Members:

Ms. Sabiha Omar (Staff nurse), Ms. Sheela Singh (Staff nurse), Ms. Richel Oliver (Matron), and Mr. Joseph Rubis (Senior Charge Nurse).

Setting/Patient group: Endoscopy Unit

Issue to be addressed:

Carbon dioxide (CO₂) gas is used for insufflation of the gastrointestinal tract during endoscopic procedures. As a potent greenhouse gas, the team explored how to streamline carbon dioxide use as well as exploring non-carbon alternatives.

Intervention:

1. Changing the routine clinical practice of leaving CO₂ cylinder taps open in between procedures to stop wasteful gas escaping.
   • Staff education to raise awareness.
   • Sustained change by regular reminders of change in daily team huddle

2. Exploration of low carbon alternatives such as air or water during endoscopic procedures.
   • Collaboration of nursing staff with hospital librarian to review literature for possible non-carbon alternatives.
   • Neither air nor water was felt clinically appropriate to trial.

Outcome:

Clinical

• No negative impact on patient care

Social

• Positive staff engagement and increased knowledge about carbon footprint reduction

Environmental

• Estimated annual carbon savings of 546kgCO2e, based on almost halving CO2 cylinder use over two-month competition period.

Economic

• Estimated annual savings of £1,226 (base on saving £204.30 over 2 months)

Key Learning:

Streamlining clinical practice collaboratively can result in substantial environmental, economic, and social benefits. Continuous monitoring and staff education are crucial for lasting change.
