Background
High blood pressure (BP) is an often treatable cause of cardiovascular disease. We developed an intervention, featuring a cardiovascular expert team and a toolbox, to support healthcare professionals (HCPs) in hypertension management and enhance patient self-management.
Aim
This study evaluates the adoption and feasibility of this intervention.
Design and Setting
A mixed-methods study in general practices in the Netherlands.
Methods
HCPs could consult a cardiovascular expert team and use a self-management toolbox for their patients as preferred. We interviewed HCPs guided by the Consolidated Framework of Implementation Research (CFIR), and HCPs completed the Determinants of Implementation Behaviour Questionnaire (DIBQ). Using CFIR-ERIC matching tool, we matched implementation strategies to identified barriers. Adults with elevated BP, who were prescribed at least two blood pressure lowering medications were eligible to participate. Patient and disease characteristics were extracted from the electronical medical record.
Results
Of 591 eligible patients at thirteen general practices, 176 participated. The cardiovascular expert team was well-received, with 33 unique consultations, although nurse practitioners (NPs) might need the expertise of the expert team more frequently than general practitioners (GP) (adoption). The toolbox was perceived as challenging to use (feasibility). We subsequently identified three key strategies to improve implementation. Mean systolic and diastolic BP were 158/87 mmHg at baseline and 148/85 mmHg after 12 months, although this change cannot be conclusively linked to the intervention.
Conclusions
Structured implementation strategies may be helpful in hypertension management. The cardiovascular expert team was considered valuable, but might be better targeted to NPs rather than GPs.
