Number of At-Risk Patients Identified by Each Hypertension Screening Algorithm
| Algorithm | Number Identified |
|---|---|
| 1. All patients whose 3 most recent encounters yielded a mean SBP >140 mm Hg or a mean DBP >90 mm. Encounters used were within 12 months before their most recent encounter | 720 |
| 2. All patients who had 3 encounters with a SBP >140 or DBP >90 mm Hg within 12 months before their most recent encounter | 968 |
| 3. Patients who had a single encounter with a SBP >180 or a DBP >100 mm Hg within 12 months before their most recent encounter | 527 |
| Unique patients identified by algorithms 1, 2, or 3 | 1,586 |
SBP = systolic blood pressure; DBP = diastolic blood pressure.
Note: All data were obtained from outpatient encounters with a primary care physician or specialist.
