The Relationship Between Preoperative and Primary Care Blood Pressure Among Veterans Presenting from Home for Surgery

American College of Cardiology/American Heart Association guidelines describe the perioperative evaluation as "a unique opportunity to identify patients with hypertension"; however, factors such as anticipatory stress or medication noncompliance may induce a bias toward higher blood pressure, leaving clinicians unsure about how to interpret preoperative hypertension. Information describing the relationship between preoperative intake blood pressure and primary care measurements could help anesthesiologists make primary care referrals for improved blood pressure control in an evidence-based fashion. We hypothesized that the preoperative examination provides a useful basis for initiating primary care blood pressure referral.
