The effectiveness of nurse-led group interventions on hypertension lifestyle management: A mixed method study

Hypertension is prevalent in Uganda and achieving treatment goals remains a challenge. Our aim was to assess the impact of a bundled nurse-led intervention on hypertension physiologic measures and lifestyle modification, and to explore perceptions of the interventions to enhance sustainability.

We employed a sequential explanatory mixed-method design. The study was conducted at a large urban private hospital in Uganda from September 2018 to May 2019.

Participants were clinic patients with hypertension currently under care. A total of 54 participants were enrolled in two study groups. Two focus groups with 16 participants and 2 nurse-educator interviews were conducted.

Blood pressure and weight were measured at baseline, three, six, and nine months. The Self-Care of Hypertension Inventory was used to assess lifestyle modification. Monthly education and group-support with text-message follow-up were implemented. Two focus-groups and nurse-educator interviews were conducted to assess perceptions post-implementation. The analysis included descriptive statistic, multivariate analysis and qualitative analysis for themes and subthemes.

Overall, participants had a mean weight loss of 7.7 kg (p = 0.001) and a mean reduction in systolic blood pressure (SBP) of 9.5 mm Hg (p = 0.001). Improvement in biometric outcomes was associated with lifestyle modification such as taking medicine as prescribed (p = 0.008), eat lots of fruit and vegetables (p = 0.043), and control your body weight (p = 0.015). Thematic analysis yielded the following themes: Knowledge and understanding, Attitude change, Adherence-a real struggle, and Adapting to what suits us. Participants found group support, shared learning, and knowledge reinforcement enhanced their knowledge and self-efficacy. Nurse educators were motivated by the patients' favorable responses to the Bundled Education and Support with Text (BEST) intervention.

Findings support the use of nurse-led interventions to enhance the achievement of hypertension treatment goals. To sustain the achieved lifestyle modification and blood pressure outcomes, participants expressed a desire for continued support, information access, and inclusion of patients as champions for knowledge dissemination. Future studies need to explore the provision of enabling structures to support nurse-led interventions in routine non-Communicable disease (NCD) care.

Hypertension knowledge-gaps exist among patients and may reflect missed opportunities for patient engagement and education for behavior change. Bundled nurse-led hypertension interventions can significantly improve lifestyle modification and enhance hypertension outcomes. Persons supported and empowered with knowledge can act as conduits to wider communities in championing knowledge dissemination.
