Last week: our paper in @BJSurgery describing the #Lifebox Surgical Headlight Project.

What is the process to address poor surgical lighting in resource-constrained operating environments?

Among 125 Million operations performed in LMICs each year, 1/3 will experience intermittent electricity or have to delay/cancel operations due to poor lighting.

The #Lifebox Surgical Headlight Project is on its way to the production of a purpose-built surgical headlight designed using human-centered principles for use in resource-constrained settings.

Stay tuned...
