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.
