Thrombocytosis refers to a platelet count above the normal range of 150-450 x109/L. It is often asymptomatic and found incidentally, but can predispose a patient to thrombotic events like deep vein thromboses and pulmonary embolism. A clear history with appropriate investigations helps determine the etiology. In essence, one must determine whether the thrombocytosis is a reactive process (secondary thrombocytosis) or a marker for a hematological disorder (primary thrombocytosis).

This one-page primer provides useful clinical information on a primary care topic. Physicians, medical trainees and other health care practitioners could use these short documents as a point-of-care tool, a reference or a study aid. Use of this information to guide clinical care must be done in the context of appropriate medical knowledge and clinical judgement.

The material is presented with a special focus on family medicine and primary care. The content is evidence-based and employs Canadian guidelines where available.

Depending on the topic, the one page PDF file will include an overview, risk factors, definitions, etiologies, diagnostic considerations, management or approach, investigations, referral guidelines, pharmacotherapy, algorithms, patient resources and the bottom line.

The topics in the DFCMOpen One Page Primer series generally address and supplement The College of Family Physicians of Canada’s “99 Priority Topics” for family medicine residents in Canada.

Creation and revision dates are clearly presented at the top of each document and references can be found online at One Pager Project References.
