This study by Victoria Hicks, Laura Riley, Rena Tchen, and Caressa Watson from the University of Pittsburgh addresses patient hazards associated with vaginal speculum use. Fault tree analysis is employed to identify possible risks, such as infection, tissue damage, pinching, contamination, overexpansion, and more. By pinpointing factors like loose screws, patient movement, user error, and negligence, the research aims to improve speculum design to enhance patient safety and prevent adverse outcomes.
