Q & A

Who is Dr. David Sackett and what is his significant achievement?

Dr. David Sackett is the founder of North America's first epidemiology department at McMaster University in Hamilton. He is also the winner of the Gairdner Award for outstanding leadership in medicine.

What is clinical epidemiology as described by Dr. Sackett?

Clinical epidemiology is the application of methodologies from public health epidemiology and biostatistics to individual patients, integrating public health disciplines into clinical medicine.

What are the three elements of evidence-based medicine according to Dr. Sackett?

The three elements of evidence-based medicine are the patient's problem and expectations, the clinician's own clinical skills, and the evidence drawn upon to make decisions about the patient's therapy.

How did Dr. Sackett react when he received the news of winning the Gairdner Award?

Dr. Sackett was initially speechless when he received the news, which he described as a condition that rarely occurs for him, only usually under anesthesia.

What historical example did Dr. Sackett provide to illustrate the importance of evidence-based medicine?

Dr. Sackett mentioned the case of George Washington, who was treated with bloodletting based on the medical authorities' suggestions of the time, which ultimately led to his death.

What is the issue with medical practices that are based on observation rather than evidence?

Medical practices based on observation rather than evidence can lead to treatments that appear effective but are not scientifically tested, potentially causing harm to patients.

Can you provide an example of a medical treatment that was once common but later found to be harmful?

Dr. Sackett mentioned the use of drugs to normalize heart rhythm in patients who had a heart attack. These drugs were found to be harmful when subjected to a randomized trial.

How did the establishment react to the introduction of evidence-based medicine?

Younger medical professionals were quick to adopt evidence-based medicine, while some senior professors, particularly in England, were resistant to the change as it challenged their established practices.

What is Dr. Sackett's view on web-based self-diagnostic tools like WebMD?

Dr. Sackett is not particularly familiar with WebMD but acknowledges the existence of many websites providing medical information. He mentions that some groups, like Brian Haynes' team at McMaster, critically evaluate medical literature for accuracy and clinical importance.

Why did McMaster University establish the first clinical epidemiology department in North America?

McMaster University was able to attract forward-looking and innovative individuals who were interested in integrating epidemiology and biostatistics with clinical skills and community medicine, leading to the establishment of the first clinical epidemiology department.

How does Dr. Sackett feel about his legacy in healthcare and medicine?

Dr. Sackett sees his legacy in the brilliant young professionals who have come through McMaster University's programs and who are now extending his work in ways that surpass his own contributions.
