Don't Let Our Operating Theatre to Be Desert

Area of Science:

• Healthcare Operations
• Environmental Sustainability
• Medical Engineering

Background:

• Preoperative hand scrubbing in operation theatres is a critical hygiene practice.
• Traditional handwashing methods may lead to substantial water wastage.
• Optimizing water usage in healthcare settings is crucial for resource conservation.

Purpose of the Study:

• To quantify water waste during medical staff hand scrubbing in operation theatres.
• To compare water consumption between sensor-activated and classic taps.
• To highlight potential water savings through simple technological interventions.

Main Methods:

• A comparative study involving two groups of participants performing hand scrubbing.
• Group A used motion-sensitive sensor taps; Group B used classic running taps.
• Water consumption was measured using a measuring cup over specified durations and extrapolated to global surgical data.

Main Results:

• Classic taps (Group B) resulted in significantly higher water consumption (22,500 ml/person) compared to sensor taps (Group A: 2,875 ml/person) over 3 minutes.
• A single operation could save 58,875 ml by using sensor taps.
• Global annual savings could reach 18,928,313 m³, equivalent to a city's water supply.

Conclusions:

• Implementing water-conserving systems like sensor taps in operation theatres can lead to substantial water savings.
• Educating healthcare professionals on efficient hand scrubbing techniques is vital for resource management.
• Adopting such measures can help conserve natural resources and reduce operational costs in healthcare facilities.
