Implementing programs to improve hypertension management in typical practice settings: not as easy as it sounds

Improving cardiovascular control in a hypertensive population in primary care. Results from a staff training intervention

OBJECTIVE

A pilot study to evaluate a staff training intervention implementing a nurse-led hypertension care model.

DESIGN AND SETTING

Clinical and laboratory data from all primary care centres (PCCs) in the Swedish region Västra Götaland (VGR), retrieved from regional registers. Intervention started 2018 in 11 PCCs. A total of 190 PCCs served as controls. Change from baseline was assessed 2 years after start of intervention.

INTERVENTION

Training of selected personnel, primarily in drug choice, team-based care, measurement techniques, and use of standardized medical treatment protocols.

PATIENTS

Hypertensive patients without diabetes or ischemic heart disease were included. The intervention and control groups contained approximately 10,000 and 145,000 individuals, respectively.

MAIN OUTCOME MEASURES

Blood pressure (BP) <140/90 mmHg, LDL-cholesterol (LDL-C) <3.0 mmol/L, BP ending on -0 mmHg (digit preference, an indirect sign of manual measuring technique), choice of antihypertensive drugs, cholesterol lowering therapy and attendance patterns were measured.

RESULTS

In the intervention group, the percentage of patients reaching the BP target did not change significantly, 56%-61% (control 50%-52%), non-significant. However, the percentage of patients with LDL-C < 3.0 mmol/L increased from 34%-40% (control 36%-36%), p = .043, and digit preference decreased, 39%-27% (control 41%-35%), p = 0.000. The number of antihypertensive drugs was constant, 1.63 - 1.64 (control 1.62 - 1.62), non-significant, but drug choice changed in line with recommendations.

CONCLUSION

Although this primary care intervention based on staff training failed to improve BP control, it resulted in improved cardiovascular control by improved cholesterol lowering treatment.

Lessons from implementing community-based group classes for severe hypertension

Due to the impact of persistent structural racism, Black men have low rates of hypertension treatment and control despite having high rates of hypertension-related mortality. Peer-based education can improve blood pressure monitoring and lower blood pressure in Black men with hypertension. To address this disparity, we implemented weekly community-based group classes for severe hypertension at a Federally Qualified Health Center. After 9 months, 28 classes were held and 96 individuals were served. Fifty-six percent of the person-hours of attendance have been by Black men. Seven individuals were interviewed about their perspectives and preferences for the classes. They reported that the peer-based model of the group classes was advantageous, and they would recommend the classes to a friend. Successes of implementation included (a) ability to facilitate medication adjustments for participants with blood pressure readings that were over target goal, (b) capacity to give participants take-home blood pressure monitors, (c) and the community-centered approach. Challenges included variability in attendance by participants and retention of individuals with uncontrolled hypertension in primary care. These findings have implications for other Federally Qualified Health Centers seeking to design similar health promotion programs and policy makers evaluating the funding and reimbursement models for community-based disease management programs.

Implementation of an Adjunct Strategy to Reduce Blood Pressure in Blacks with Uncontrolled Hypertension: a Pilot Project

A high prevalence of uncontrolled hypertension among Blacks is a major cause of racial health disparities in the United States. We established a community/academic partnership to improve hypertension control in Blacks receiving medical care at a federally qualified health center in Milwaukee. The defining components of our program included: six group sessions (one/month), based on the American Heart Association's Simple Seven curriculum and designed to motivate and empower patients to manage their blood pressure; active involvement of a community health worker; and ongoing participation of a community advisory board. The study design included a matched control group not exposed to the intervention. Patients in both groups received their usual medical care. Overall, compared to baseline, systolic blood pressure decreased at both 6 and 12 months (P < 0.004); however, the reduction of blood pressure in the intervention and control groups did not differ significantly (P = .62). Based on written responses to a questionnaire and structured focus group interviews after completing the six-month program, participants reported that the intervention was effective. In retrospect, they suggested that more attention might have been given to spirituality and stress reduction. Larger and longer-term studies will be required to evaluate the added value of this type of intervention.
