Brief summary

Elevated blood pressure is the largest contributing risk factor to all-cause and cardiovascular mortality. According to the U.S. Preventive Services Task Force, hypertension affects nearly 30% of the adult population. Many patients remain undiagnosed, despite the consensus that screening and timely diagnosis is paramount. In this study, 108 ambulatory surgery patients with elevated blood pressure (160/90) that are not yet formally diagnosed with hypertension will be enrolled and alerted of their high blood pressure by a co-investigator MD. They will request permission to follow-up with the patient and the patient's primary care provider 6 months after the initial phone call to check in on the status of their diagnosis and any action taken (lifestyle changes, medication) to alleviate their high blood pressure. Patients will receive a follow-up letter/email at 6 and 3 months to remind them of their potential diagnosis.

Interventions

OTHERAnesthesiologist phone call

Patients receiving ambulatory surgery with no prior diagnosis of hypertension but have elevated blood pressure prior to surgery. Patients will receive a phone call from a participating anesthesiologist 1-3 days after surgery notifying them of their high blood pressure and obtaining oral consent to participate in the study. Patients will receive reminders via mail about following up with their PCP.
