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.
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.
Study Type

Yale-New Haven Hospital PreAdmission Testing Clinic
New Haven, Connecticut, United States
Performance of Blood Pressure Referral Threshold
The positive predictive value of preadmission testing-measured blood pressure to predict mean home blood pressure \>135/85mmHg will be calculated.
Time frame: Subjects followed for approximately 1 year
Patient Perspectives and Beliefs Regarding Blood Pressure Status as They Relate to Actual Home Blood Pressures.
In secondary analyses, the agreement between patients' self-reported blood pressure control (binary outcome) and home blood pressure monitor-determined blood pressure status (binary outcome) will we assessed via Cohen's kappa and raw indices of agreement.
Time frame: Approximately 60 days
Preidentified Subgroups
The investigators will examine the correlation between blood pressure and heart rate in the subset of patients with hypertension diagnosis.
Time frame: 1 year
Patient Perspectives
The possible association of self-reported availability of primary care (5 point LIKERT scale) with home blood pressure monitor-status will be examined by the Mantel-Haenszel Chi-Square Test.
Time frame: 60 days
Patient Adherence
The possible association of medication adherence (Morisky scale) with home blood pressure monitor-status will be examined by the Mantel-Haenszel Chi-Square Test.
Time frame: 60 days
Preidentified Subgroup Analysis
The investigators will examine the correlation between blood pressure and heart rate in the subset of patients without hypertension diagnosis.
Time frame: 1 year
