The Lifebox Surgical Headlight Project: engineering, testing, and field assessment in a resource-constrained setting

Area of Science:

• Surgical Technology
• Medical Device Evaluation
• Global Health

Background:

• Poor surgical lighting is a significant patient safety concern in low-income countries.
• High-quality surgical headlights are essential for improving surgical outcomes in resource-limited environments.

Purpose of the Study:

• To evaluate the performance of high-quality surgical headlights.
• To identify critical attributes for improving surgical safety and encouraging local adoption in Ethiopia.
• To assess surgeon preferences and willingness to purchase devices for resource-constrained settings.

Main Methods:

• Twenty-five medical and technical headlights were submitted for evaluation.
• Devices underwent specification testing on 14 parameters, including light quality, intensity, mounting, and battery performance.
• Five top-performing devices were field-tested by eight Ethiopian surgeons in operating rooms.

Main Results:

• No headlight met all predetermined specifications; only two exceeded 35,000 lux.
• Surgeons' opinions on lighting quality and spot size varied significantly.
• Price sensitivity was high, with surgeons preferring the least expensive, high-functioning device.

Conclusions:

• Significant price discrepancies and unmet specifications influenced surgeons' choices.
• The favored device is being modified based on surgeon feedback to create an affordable, high-quality option.
• Development of tailored, cost-effective surgical headlights is crucial for enhancing surgical safety in resource-constrained settings.
