Solving the information overload problem: a letter from Canada.

Doctors are inundated with medical information, some inadequately evidence-based, much of it captured in clinical practice guidelines (CPGs). The Ontario Guidelines Advisory Committee (GAC) selects topic areas, searches for all CPGs on the topic, and reviews them using the AGREE Instrument. Based in large part on the AGREE score, the GAC summarises one guideline in each topic area and mounts it on its website, with links to other information (eg, clinical algorithms) where possible. Two topic areas have been selected for implementation--the reduction of unnecessary preoperative testing and the rational management of acute low back pain. Implementation strategies include performance feedback, training of opinion leaders, development of algorithms and reminders, and communication through journals and continuing medical education activities.
