Adherence to Blood Pressure Diaries With Personalized Visuals

January 6, 2024 updated by: Clemens Farr, Medical University of Vienna

Picture This: A Randomized Controlled Pilot Study Investigating Adherence to Blood Pressure Diaries With Personalized Visuals

This trial randomizes patients with a neurovascular diagnosis to a type of blood pressure diary for secondary stroke prevention (conventional blood pressure diary or blood pressure diary including patient-provided images). Outcomes include adherence and patient-reported outcomes.

Study Overview

Detailed Description

In this prospective trial, the investigators randomized persons with diagnoses of stroke or transitoric ischemic attack into two groups: (i) 10 patients received a personalized blood pressure diary with pictures of their choosing. (ii) 10 patients received a blood pressure diary without photographs. The investigators instructed participants in either group to document their blood pressure at home twice daily over twenty-eight days.

How is the study designed?

Design Details

  • Primary Purpose: Prevention
  • Allocation: Randomized
  • Interventional Model: Parallel Assignment
  • Masking: Single

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Active Comparator: Conventional blood pressure diary
Blood pressure diaries consisted of tables including columns for date, time as well as systolic and diastolic blood pressure respectively (1 page for 1 week) printed on the right-hand pages of an A5 (ISO 216 format) booklet.
Conventional blood pressure diary
Experimental: Blood pressure diary including patient-provided pictures
In the interventional arm pictures chosen by patients were provided over a secure online connection by patients in this group and inserted into the left-hand-pages of the blood pressure diaries.
Patient-provided pictures with positive meaning were included into blood pressure diaries

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Adherence
Time Frame: 28 days
The primary endpoint was adherence to blood pressure diaries defined as the number of complete blood pressure measurements (maximum of two per day) divided by the maximum number of measures over the study period (28 days, resulting in a maximum total of 56 measurements). Complete entries were defined as diary entries stating date, time and systolic as well as diastolic blood pressure.
28 days

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Blood pressure
Time Frame: 28 days
Mean raw values of systolic and diastolic blood pressure
28 days
Precision of documentation of blood pressure
Time Frame: 28 days
The proportion of documented values ending with "0" or "5" served to assess the extent of rounding (i.e. the precision of documentation)
28 days
Patient Global Impression of Change Scale
Time Frame: 28 days
The Patient Global Impression of Change Scale is a self-report rating scale of 1 item on a Likert scale (maximum 7, higher score is better) and 1 item on a scale from 0-10 (higher score is worse). It was applied to assess patient satisfaction.
28 days
36-Item Short Form Health Survey
Time Frame: 28 days
The 36-Item Short Form Health Survey is a self-report survey of items on a Likert Scale in 8 domains. It is designed to assess quality of life. The maximum amount of points is 100. More points are better.
28 days
Hospital Anxiety and Depression Scale
Time Frame: 28 days
The Hospital Anxiety and Depression Scale is a self-report rating scale of 14 items on a Likert scale. It is designed to measure anxiety and depression (7 items for each subscale). The maximum amount of points in each subscale is 21. More points are worse.
28 days

Other Outcome Measures

Outcome Measure
Measure Description
Time Frame
Exploratory endpoints
Time Frame: 28 days
Exploratory endpoints evolved around patients' perspectives on blood pressure diaries as assessed by an empirical survey (13 questions in each group) conceived for this study. Possible answers were Likert-type scales, yes/no or open commentaries.
28 days
