Using qualitative research and the person-based approach to coproduce an inclusive intervention for postpartum blood pressure self-management.

Objective: To coproduce an inclusive intervention for blood pressure (BP) self-management post partum.

Design: Using the person-based approach, an intervention was coproduced in three phases. Phase 1 entailed intervention coproduction with a diverse patient and public involvement panel and stakeholders (clinical, academic, government and third sector-based). Phase 2 involved intervention optimisation through think-aloud interviews with former patients and clinicians. Phase 3 was user-testing followed by semistructured interviews with current patients and their clinicians.

Setting: Patients and clinicians from primary and secondary care drawn from Southern and Northern England.

Participants: Seven former patients and 11 clinicians participated in think-aloud interviews to provide their views of intervention prototypes (phase 2). Additionally, 23 patients and 9 of their clinicians participated in semistructured interviews after using the intervention for 2 weeks (phase 3).

Intervention: An interactive patient app-My BP Care-and accompanying leaflet to support BP self-monitoring. These were linked to a clinician dashboard with alerts and an emailing system to facilitate appropriate titration of patient medication.

Results: The intervention was codeveloped following these guiding principles to ensure it was accessible and inclusive: easily comprehensible, motivating, simple and quick to use. Interview findings indicated that patient adherence to the intervention was promoted by the initial patient training conducted by the midwives, the enhanced clinical oversight they felt they received as a result of the intervention, the free BP monitor they received, reassurance they received of the medication safety for them and their baby, the intervention's simplicity and the motivating reminders they received.

Conclusions: Through coproduction with a diverse group of patients and stakeholders, and optimisation through testing among further diverse patients and clinicians, we developed a multicomponent intervention that is accessible and engaging for diverse patients, compatible with prevailing clinical practice and adaptable to different clinical contexts.
