Doctors increasingly treat people using tiny cameras, and some patient-safety experts are urging physicians to hit the record button.
Marty Makary, a surgeon at Johns Hopkins School of Medicine and author of a bestselling book on patient safety, said two examples of video recording show the potential benefits for both patients and doctors.
At Indiana University, he said, researchers recorded 98 colonoscopies performed by seven gastroenterologists. They were unaware that they were being filmed and researchers found wide variations in quality.
After telling them they were being filmed, the mean inspection time increased 49% and the quality of inspection improved 31%.
"There is tremendous potential if we want to take quality to the next level and get serious about waste in healthcare," Makary said. "We should utilize the record button that is already there on these devices."
