    Author: Shah SJ, Stafford RS.
    Journal: Am J Hypertens; 2017 Oct 01; 30(10):1008-1014. PubMed ID: 28531239.
    Abstract:
    BACKGROUND: To examine current patterns of hypertension (HTN) treatment in the United States, including blood pressure (BP) control, prevalence of different antihypertensive agents, and variations in treatment associated with patient and physician characteristics. METHODS: We used data from the National Disease and Therapeutic Index (NDTI), a nationally representative physician survey produced by QuintilesIMS. We selected patients with a diagnosis of HTN and identified those prescribed antihypertensive therapies. We analyzed the type of antihypertensive agents prescribed. Extent of BP control, and associated patient and physician characteristics. We calculated 95% confidence intervals that accounted for the multistage NDTI sampling design. RESULTS: Among those treated for HTN in 2014, BP control varied: systolic BP (SBP) ≥160 (15%) vs. SBP 150-159 (9%) vs. SBP 140-149 (19%) vs. SBP 130-139 (26%) vs. SBP <130 (32%). Of those treated for HTN, 29% used of angiotensin-converting enzyme inhibitors (ACEIs); 24%, thiazide-like diuretics; 22%, angiotensin receptor blockers (ARBs), 21%, calcium-channel blockers (CCBs); and 19% beta-blockers. Newer drugs had very limited uptake; no drugs approved after 2002 were used in more than 5% of patients. Selection of agents varied only modestly by patient and physician characteristics. CONCLUSIONS: The treatment of HTN in 2014 predominantly involved older medications in 5 major classes of drugs: ACEIs, thiazide diuretics, ARBs, CCBs, and beta-blockers. Selection of antihypertensive agents showed limited variation by age, gender, race, and insurance type. Although 58% of treated patients had SBP <140, 24% had poorly controlled HTN with SBP ≥150, indicating the need for improved treatment.
