Pressure points in primary care
Key result
Antihypertensive therapy was associated with 3- to 4-fold higher odds of elevated blood pressure (>140/90 mmHg) compared to untreated individuals (yearly range OR 3.0-3.97).
Why the study?
Does antihypertensive therapy and visit frequency improve blood pressure control in primary care patients?

Implication
Treated patients show poorer BP control; leaves open whether intensified visits or therapy improve outcomes in primary care.

Structured PICO
Does antihypertensive therapy and visit frequency improve blood pressure control in primary care patients?
P
Population
532,050 patients (55% women, mean age 54 years) with at least one recorded blood pressure visit between 2005 and 2010 across 286 primary care clinics in Australia.
E
Exposure
Antihypertensive therapy and frequency of primary care visits
C
Comparator
No antihypertensive therapy and less frequent visits
O
Outcome
Trends in blood pressure (BP) and hypertensive management (attainment of target BP <140/90 mmHg)surrogate
Main Result
Effect estimate: OR 3.0-3.97 (95% CI 2.93-3.83 to 3.08-4.10)
Despite antihypertensive therapy, a significant proportion of primary care patients in Australia fail to achieve target blood pressure, highlighting the need for more intensive management.

Carrington et al. (2013) conducted an observational in Hypertension (n=532,050). Antihypertensive therapy vs. No antihypertensive therapy was evaluated on Elevated blood pressure >140/90 mmHg (OR 3.0-3.97, 95% CI 2.93-3.83 to 3.08-4.10). Antihypertensive therapy was associated with 3- to 4-fold higher odds of elevated blood pressure (>140/90 mmHg) compared to untreated individuals (yearly range OR 3.0-3.97).
