Abstract 11089: Hypertension Control (or Lack Thereof) Among Patients Followed Routinely in Cardiology Clinics
Background: Hypertension (HTN) is highly prevalent among cardiac patients, yet few data exit on HTN control rates among patients treated routinely in cardiology clinics.
Methods: We evaluated patients with an established diagnosis of HTN seen routinely (2+ times/year) in cardiology clinics at a major academic medical center from 6/1/2009 to 6/31/2010. Uncontrolled HTN was defined per JNC7 guidelines. Multivariable random effects logistic regression was used to identify factors associated with HTN control and to quantify heterogeneity between providers. Manual chart reviews (n=300) were conducted to evaluate provider therapeutic responses to uncontrolled blood pressure.
Results: Overall, 30% of routinely followed HTN patients (n=6,485) had uncontrolled HTN at their latest visit in the window evaluated. Uncontrolled HTN rates varied significantly among provider, ranging from 16% to 45% (Figure 1). Provider differences persisted after adjusting for patient factors (≈3-fold variation across providers, p=0.02). Chart reviews found that of those eligible, only 51% of those with uncontrolled HTN had a documented therapeutic intervention at their last visit.
Conclusions: HTN control rates are non-ideal even among those routinely followed in cardiology clinics. Control rates vary considerably by provider. Uncontrolled HTN is often not aggressively treated. These data suggest that outpatient HTN control may be a good target for quality improvement in cardiology clinics.
