Journal of Ambulatory Care Management: January-February-March 2005 - Volume 28 - Issue 1 - p 86-97 Buy Abstract There is a great deal to be learned about how factors within the context of primary care influence the provision of comprehensive preventive services. This study assessed the prevalence of cancer screening among a primary care population of men and women and examined the association of characteristics of the patient-physician relationship, the healthcare facility, and type of health insurance. Findings suggest that prevalence of comprehensive cancer screening is low, particularly among men. Characteristics of the patient-physician relationship are an important predictor of screening among women but not men. Among men, however, greater contact with the medical care system is important. © 2005 Lippincott Williams & Wilkins, Inc.
