A 68-year-old retired schoolteacher, Ms. Eleanor Vance, presents to her family physician's office in Saskatoon, Saskatchewan, with persistent, worsening abdominal pain and weight loss over three months. After an initial assessment and some inconclusive blood tests, the physician, Dr. Arndt, suspects a complex gastrointestinal issue and refers Ms. Vance for a colonoscopy. Due to a backlog at the local hospital, the procedure is delayed by several weeks. During the colonoscopy, performed by a gastroenterologist, a previously undiagnosed large polyp is found and successfully removed. However, post-procedure, Ms. Vance develops significant abdominal distension and fever, leading to a diagnosis of iatrogenic colonic perforation requiring emergency surgical repair. Ms. Vance's recovery is prolonged, necessitating an extended hospital stay and further rehabilitation. She is now considering her options regarding the adverse outcome.Which of the following best describes the most appropriate initial course of action for Dr. Arndt and the hospital concerning this adverse event, from a medical-legal perspective?
