title: Blood pressure control and pharmacotherapy patterns in the United States before and after the release of the Joint National Committee on the Prevention, Detection, Evaluation, and Treatment of High Blood Pressure (JNC 7) guidelines.
abstract: OBJECTIVE
  Despite recommendations from the Joint National Committee on the Prevention, Detection, Evaluation, and Treatment of High Blood Pressure (JNC 7), only 36.8% of patients were at target blood pressure (BP) in 2003 and 2004. The objective of this study was to assess improvements in BP control and treatment patterns before and after the publication of JNC 7.
  
  
  METHODS
  This was a retrospective, time series analysis of 27 provider groups and managed care organizations from 1998 through 2006. Patients with hypertension were identified from more than 4000 physicians. Medical charts were collected and clinical data were evaluated using prevailing JNC criteria during the time period before and after JNC 7.
  
  
  RESULTS
  A total of 19,258 patients were identified with hypertension: 15,258 included in the before-JNC 7 cohort and 4,000 in the after-JNC 7 cohort. BP control in the before-JNC 7 cohort was 40.8% compared with 49.3% in the after-JNC 7 cohort (P < .0001). After controlling for demographic and clinical covariates, patients in the before-JNC 7 cohort were 45% less likely to achieve BP control compared with the after-JNC 7 cohort (odds ratio, 0.551; P < .0001).
  
  
  CONCLUSIONS
  Although findings indicate BP control is improving, a significant need for further improvement remains.
