Positive Predictive Values of Algorithms for Identifying Patients at Risk of Undiagnosed Hypertension Screening
| Algorithm | Patient Identified as at Risk and Completed AOBP | Patient Hypertensive by AOBPa | PPV % | 95% CI % |
|---|---|---|---|---|
| 1 | 234 | 136 | 58 | 51–65 |
| 2 | 321 | 168 | 52 | 47–58 |
| 3 | 138 | 70 | 51 | 42–59 |
| Any | 475 | 249 | 52 | 48–57 |
AOBP = automated office blood pressure; PPV = positive predictive value.
