The Surgery Safety Checklist is an app based on the World Health Organizations Surgical Safety Checklist. It uses a simple, intuitive interface to track the checklist though the the stages of a surgical procedure. Help screens are included, along with links to the definitive WHO resources. Users tap on-screen checkboxes to signify that items are complete, and the main screen displays a tally of which items have been completed, along with a list of risk factors identified for the procedure.
