Dr. Alana Chen, a family physician in Winnipeg, Manitoba, sees Ms. Evelyn Dubois, a 78-year-old woman with chronic widespread musculoskeletal pain and a complex history of polysubstance use in remission. Ms. Dubois has been seen by multiple specialists over the years and expresses significant frustration with her previous physicians, stating she often feels rushed and unheard. During her initial consultation with Dr. Chen, Ms. Dubois presents a lengthy list of symptoms and past unsuccessful treatments, speaking at length. Dr. Chen, feeling pressed for time due to a busy clinic schedule, interrupts Ms. Dubois multiple times to redirect the conversation towards a focused history, offering a generalized pain management plan without fully exploring the patient's expressed concerns about her social isolation and previous negative experiences with medication side effects. Ms. Dubois subsequently files a complaint with the College of Physicians and Surgeons of Manitoba, alleging Dr. Chen exhibited impatience and failed to adequately address her complex needs with empathy. Which of the following ethical principles is most directly challenged by Dr. Chen's approach in this scenario?
