This document outlines a research study to identify the medical devices most commonly causing injuries to hospital workers at Massachusetts Eye and Ear Infirmary and ways to prevent such injuries. The study will analyze injury data from 2009-2014 to determine which procedures and devices have the highest injury rates. The goal is to identify the most dangerous devices and see if safer alternatives exist. New safety strategies will then be developed and implemented based on the findings. The results will also be compared to state-level injury data and compiled into a central database for future reference.
