Impact of educational mailing on the blood pressure of primary care patients with mild hypertension
Open accessAbstract
Objective To assess the effectiveness of mailed hypertension educational materials.Design Prospective, randomized, controlled single-blind trial.Setting Primary care practice-based research network in which 9 clinics located in Portland, Oregon participated.Participants Patients with mildly uncontrolled hypertension as defined as a last blood pressure of 140 to 159/90 to 99 mmHg from query of an electronic medical record database.Interventions Patients randomized to intervention were mailed 2 educational packets approximately 3 months apart. The first mailer included a letter from each patient's primary care provider. The mailer included a booklet providing an overview of hypertension and lifestyle modification and a refrigerator magnet noting target blood pressure. The second mailing also included a letter from the patient's primary care provider, a second educational booklet focused on medication compliance and home blood pressure monitoring, and a blood pressure logbook. The control group consisted of similar patients receiving usual care for hypertension.Measurements and main results Patients from each group were randomly selected for invitation to participate in a study visit to measure blood pressure and complete a survey (intervention n= 162; control n= 150). No significant difference was found in mean blood pressure between intervention and control patients (135/77 mmHg vs 137/77 mmHg; P=.229). Patients in the intervention arm scored higher on a hypertension knowledge quiz (7.48 +/- 1.6 vs 7.06 +/- 1.6; P=.019), and reported higher satisfaction with several aspects of their care. No significant difference was seen in the prevalence of home blood pressure monitoring ownership or use.Conclusions In patients with mildly uncontrolled hypertension, educational mailers did not yield a significant decrease in blood pressure. However, significant improvement in patient knowledge, frequency of home monitoring, and satisfaction with care were demonstrated.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
