Abstract 4899: Improved Blood Pressure Control and Lack of Gender Bias in a Large Veterans Affairs Population
Introduction: Despite the proven benefits, blood pressure (BP) control rates remain low. Gender bias has emerged in several aspects of treatment of cardiovascular disease. Thus, we assessed the effect of interventions to control blood pressure in men and women in the Department of Veteran Affairs.
Methods: From January of 2001 to December 2007, we assessed BP control in 460,278 men and 17,821 women patients from 15 VA hospitals in the United States. Medical interventions to control BP included use of electronic medical records with automated reminders, medical regimen adjustments, and frequent visits to both specialty and nurse run clinics.
Results: Control rates (BP ≤ 140/90) over time are shown (Figure⇓). In Jan 2001 control rates were: 43.8% for men and 47.0% for women (p < 0.001) and in June 2001 were 51.8% for men and 54.2% for women (p < 0.001). After 7 years of follow up, control rates improved in both genders as follows: Jan 2007, 67.3% for men and 67.6 for women (p = NS), June 2007, 72.9% for men and 72.9% for women (p = NS, p < 0.001 for seasonal differences). Overall during the follow up period while there was a 23.1% increase in control rates for men and 19.2% for women (p = 0.007), the final control rate was the same.
High rates of BP control can be achieved in both men and women.
Although early on more women than men were controlled, the control rates were identical at the end of the follow up period.
No gender bias was detected for blood pressure treatment and control in this cohort.
Seasonal BP variation was seen in both genders throughout the follow up period.
