Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Acceptability and feasibility of the intervention and a future definitive RCT. This will be measured through: 1. Recruitment of GP practices will be assessed by documenting the number of invitations sent, the number of refusals and the number of acceptances throughout the study 2. Recruitment of patients will be assessed by documenting the number of invitations sent, the number of initial responses, the number of follow-up phone calls required, the number of refusals and the number of acceptances throughout the study 3. Attrition of participants will be documented at every timepoint throughout the study 4. Levels of missing data in returned questionnaires will be reported at baseline and follow up 5. The comprehensibility and acceptability of all questionnaires will be measured by asking participants how the questionnaires might be improved and how long they took to complete at baseline and follow up 6, The perceptions and experiences of people with hypertension and GPs of participating in the MIAMI intervention and their views as to the feasibility and acceptability of the intervention, explored using qualitative interviews at the mid-point of the intervention | — |
Secondary
| Measure | Time frame |
|---|---|
| 1. Systolic blood pressure (ambulatory blood pressure monitoring [ABPM], average reading) measured at baseline and follow up 2. Diastolic blood pressure (ABPM, average reading) measured at baseline and follow up 3. Blood pressure control (ABPM, reading above or below 140/90mmHg) measured at baseline and follow up 4. Medication adherence (urine screen, prescription refill records, Medication Adherence Report Scale (MARS) measured at baseline and follow up 5. Beliefs about medication (Beliefs about Medication Questionnaire (BMQ), Illness Perceptions Questionnaire - Revised (IPQ-R) 'treatment control' and 'consequences' items) measured at baseline and follow up 6. Habit strength measured using the Self-Report Behavioural Automaticity Index (SRBAI) at baseline and follow up 7. Pill burden (type and dosage) measured at baseline and follow-up 8. Health related quality of life measured using EuroQol-5D-5L at baseline and follow-up 9. Wellbeing measured using ICEpop CAPability measure for Older people (ICECAP-O) at baseline and follow up | — |
