The association of health literacy and blood pressure reduction in a cohort of patients with hypertension: The heart healthy lenoir trial.

ABSTRACT:

Objective

Lower health literacy is associated with poorer health outcomes. Few interventions poised to mitigate the impact of health literacy in hypertensive patients have been published. We tested if a multi-level quality improvement intervention could differentially improve Systolic Blood Pressure (SBP) more so in patients with low vs. higher health literacy.

Methods

We conducted a non-randomized prospective cohort trial of 525 patients referred with uncontrolled hypertension. Stakeholder informed and health literacy sensitive strategies were implemented at the practice and patient level. Outcomes were assessed at 0, 6, 12, 18 and 24 months.

Results

At 12 months, the low and higher health literacy groups had statistically significant decreases in mean SBP (6.6 and 5.3mmHg, respectively), but the between group difference was not significant (Δ 1.3mmHg, P=0.067). At 24 months, the low and higher health literacy groups reductions were 8.1 and 4.6mmHg, respectively, again the between group difference was not significant (Δ 3.5mmHg, p=0.25).

Conclusions/practice implications

A health literacy sensitive multi-level intervention may equally lower SBP in patients with low and higher health literacy. Practical health literacy appropriate tools and methods can be implemented in primary care settings using a quality improvement approach.

Project description:Background The impact of the new 2017 American College of Cardiology/American Heart Association (ACC/AHA) hypertension guideline on dementia risk at the population level has not been evaluated. Methods and Results We studied dementia-free participants in the ARIC (Atherosclerosis Risk in Communities) Study cohort in 1987 to 1989. Hypertension was defined by 2003 Seventh Report of the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure and 2017 ACC/AHA guidelines using blood pressure measured at baseline. Dementia was defined using adjudicated consensus diagnoses, informant telephone interviews, and discharge codes from hospitalizations and death certificates. Cox regression estimated hazard ratios (HRs) for dementia and 95% CIs by hypertension categories, adjusting for confounders. Population attributable fraction of dementia was calculated by hypertension categories. Among 13 971 participants followed up for a median of 23 years, 1381 dementia cases were identified. Prevalence of hypertension was 34% and 48%, according to the Seventh Report of the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure and ACC/AHA criteria, respectively. HRs (95% CIs) compared with normal blood pressure, according to ACC/AHA categories, were 1.35 (1.12-1.61) for elevated blood pressure, 1.28 (1.07-1.52) for hypertension stage 1, and 1.36 (1.18-1.57) for hypertension stage 2. Population attributable fractions (95% CIs) of dementia from blood pressure categories were 3% (1%-5%), 3% (1%-5%), and 9% (4%-14%), respectively. Population attributable fractions (95% CIs) using the Seventh Report of the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure categories were 6% (3%-9%) for prehypertension, 0% (-2% to 2%) for hypertension stage 1, and 9% (5%-13%) for hypertension stage 2. Conclusions Risk of dementia increased across hypertension categories defined by ACC/AHA guidelines. The population impact on dementia incidence using ACC/AHA categories was similar to the impact of the Seventh Report of the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure.

Project description:IntroductionThe 2017 American College of Cardiology/American Heart Association blood pressure guideline redefined hypertension and lowered the blood pressure treatment target. Empirical data on the guideline's impact are needed.MethodsData were analyzed from Atherosclerosis Risk in Communities study participants who attended baseline pre-guideline (2016-2017) and post-guideline (2018-2019) visits with baseline systolic blood pressure between 120 and 159 mmHg. Participants were grouped according to baseline systolic blood pressure by change in classification under the new guideline as follows: not reclassified (120-129 mmHg), reclassified to Stage 1 hypertension (130-139 mmHg), and reclassified to Stage 2 hypertension (140-159 mmHg). Means and 95% CIs for systolic blood pressure changes between baseline and follow-up, changes in antihypertensive use, and percentages that achieved the post-guideline recommendation (systolic blood pressure <130 mmHg) were calculated. Analyses were performed in 2021-2022.ResultsAmong 2,193 community-dwelling Atherosclerosis Risk in Communities participants aged 71-95 years at baseline, systolic blood pressure changes between baseline and follow-up visits differed among participants not reclassified (+4.1 mmHg, 95% CI=3.0, 5.3 mmHg), reclassified to Stage 1 hypertension (-1.1 mmHg, 95% CI= -2.2, 0.1 mmHg), and reclassified to Stage 2 hypertension (-5.7 mmHg, 95% CI= -6.8, -4.7 mmHg). Antihypertensive use changed from 77.3% to 78.4% (p=0.25) among participants reclassified to Stage 1 hypertension and from 78.3% to 81.4% (p<0.01) among participants reclassified to Stage 2 hypertension. At follow-up, 41.8% of the Stage 1 and 22.4% of the Stage 2 hypertension groups reached the systolic blood pressure <130 mmHg goal.ConclusionsThere were small decreases in systolic blood pressure and increases in antihypertensive therapy among older adults reclassified to Stage 2 hypertension but not among those reclassified to Stage 1 hypertension by the 2017 American College of Cardiology/American Heart Association guideline.
