To examine if the use of general preventive services were diminished in a cohort of men following their diagnosis of prostate cancer.
16,604 men enrolled in Kaiser Permanente Southern California who were newly diagnosed with prostate cancer from January 1, 2002 through December 31, 2009 were passively followed through electronic medical records to determine the use of preventive services, including screening for colorectal cancer (colonoscopy and/or fecal occult blood tests (FOBT)), tests for diabetes (glucose and hemoglobin A1c) and heart disease (serum cholesterol, high density lipoprotein (HDL) and triglycerides) and vaccinations (influenza and pneumococcal).
