Background: Although the ambulatory setting is recognized as the best arena for optimizing antihypertensive drug treatment after a stroke, little is known about recent office-based antihypertensive drug treatment patterns in the United States. We assessed national trends in antihypertensive treatment for stroke patients in office-based medical practice.
Methods: Data from the 2000-2009 National Ambulatory Medical Care Surveys were analyzed comprising outpatient visits to physicians in office-based practice by patients aged 40 years or older with a diagnosis of stroke (weighted estimate=46,317,269). The main outcome measure was visits with a prescription of antihypertensive medication(s).
Results: The proportion of total visits that included a prescription of antihypertensive medication was 35.6% in 2000-2002, 29.5% in 2003-2005, and 49.3% in 2006-2009 (P=.002); 50.9% were primary care physician (PCP) visits versus 26.2% neurologist visits (P<.0001). Age-adjusted logistic regression analyses confirmed a higher prescription rate in 2006-2009 versus 2000-2002 (1.81; 95% confidence interval [CI], 1.10-2.96) and PCP versus neurologists (2.82; 95% CI, 1.86-4.27). Use of 2 or more agent classes was 31.6% in 2000-2002, 44.2% in 2003-2005, and 56.7% in 2006-2009 (P=.014). Age-adjusted logistic regression analyses confirmed a higher prescription rate of 2 or more agent classes in 2006-2009 versus 2000-2002 (2.96; 95% CI, 1.40-6.24). There were no significant differences in agent class type or number between neurologists versus PCPs.
Conclusions: Over the last decade, there was a significant rise in the use of antihypertensive drugs and combination of agent classes for patients aged 40 years or older seen in an ambulatory setting with a diagnosis of stroke. PCPs were more likely than neurologists to prescribe these agents.
