Study population: Ambulatory surgical patients \>= 21 years of age presenting for preadmission testing to a tertiary care hospital and who demonstrate elevated clinic blood pressures greater than or equal to 130/85mmHg.

Brief summary: This study aims to assess the performance of presurgical clinic blood pressure measurements in predicting home blood pressure readings among surgical patients. It also aims to measure the association between home blood pressures and patient perspectives on blood pressure control.

Detailed description: A convenience sample of presurgical patients seen in a preadmission testing clinic were enrolled and sent home with a home blood pressure monitor that stored up to 50 readings. Participants were asked to return the BP cuff on the day of their surgery.

Eligibility criteria: Inclusion Criteria:

* Ambulatory patients \>= 21 years of age presenting for surgery to a tertiary care preadmission testing clinic.

Exclusion Criteria:

* Inability or unwillingness to independently operate a home blood pressure monitor.
