Background
While 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 of stroke patients in office-based medical practice.
Methods
Datafrom the 2000-2009 National Ambulatory Medical Care Surveys were analyzed comprising outpatient visits to physicians in office-based practice by patientsaged ā„ 40 yearswith 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 medicationwas 35.6% in 2000-2002, 29.5% in 2003-2005, and 49.3% in 2006-2009 (p=0.002);50.9% were primary care physician (PCP) visits vs.26.2% neurologist-visits (<0.0001).Age-adjusted logistic regression analyses confirmed a higher prescription rate in 2006-2009 vs. 2000-2002 (1.81, 95% CI=1.10-2.96) and PCP vs. neurologists (2.82, 95% CI=1.86-4.27). Use of two or more agent classes was 31.6% in 2000-2002, 44.2% in 2003-2005, and 56.7% in 2006-2009 (p=0.014). Age-adjusted logistic regression analyses confirmed a higher prescription rate of ā„ 2 agent classesin 2006-2009 vs. 2000-2002 (2.96, 95% CI=1.40-6.24). There were no significant differences in agent class type or number between neurologists vs. PCPs.
Conclusion
Over the last decade, there was a significant rise in use of antihypertensive drugs and combination of agent classes for patients agedā„ 40 years seen in an ambulatory setting with a diagnosis of stroke. PCPs were more likely than neurologists to prescribe these agents.
