A randomized controlled trial of an information booklet for hypertensive patients in general practice

Area of Science:

• Cardiology
• Public Health
• Health Education

Background:

• Hypertension management requires effective patient education and engagement.
• Standard care may not fully optimize patient understanding of hypertension.
• Patient information booklets are a potential tool to enhance self-management.

Purpose of the Study:

• To evaluate the effectiveness of an information and medical record booklet in improving patient understanding and participation in hypertension management.
• To assess the impact of the booklet on blood pressure control.
• To determine the acceptability of the booklet for healthcare professionals.

Main Methods:

• A randomized controlled trial was conducted in six inner London general practices.
• Participants were assigned to receive either the information booklet or standard care (control group).
• Outcomes including blood pressure and knowledge about hypertension were assessed after one year.

Main Results:

• No significant differences were observed in mean systolic or diastolic blood pressure between the groups after one year.
• The group receiving the booklet demonstrated significantly higher scores in knowledge about hypertension and its management.
• The observed differences in knowledge were small, potentially due to a high baseline understanding in both groups.

Conclusions:

• The information booklet significantly improved patient knowledge of hypertension but did not lead to better blood pressure control.
• The booklet is a highly acceptable method for informing patients about hypertension and its management.
• This tool can be effectively utilized by healthcare professionals in both hospital and general practice settings.
