Abstract/Description

Background
Hypertension is generally poorly controlled in primary care. One possible intervention for improving control is the harnessing of patient expertise through education and encouragement to challenge their care.


Aim
To determine whether encouraging patients to manage their hypertension in an ‘expert’ manner, by providing them with information in a clear clinical guideline, coupled with an explicit exhortation to become involved in and to challenge their own care if appropriate, would improve their care.


Design of study
Single blind randomised controlled trial of detailed guideline versus standard information.


Setting
Single urban general practice over 1 year.


Method
Patient-held guideline with written explicit exhortation to challenge care when appropriate. Two hundred and ninety-four of 536 eligible patients on the practice hypertension register were recruited, all of whom were randomised into one of two groups. Two hundred and thirty-six patients completed the study.


Results
Primary outcome: average systolic blood pressure. Secondary outcomes: proportion of patients with blood pressure <150mmHg systolic and <90mmHg diastolic, average cholesterol, proportion of patients prescribed statins and aspirin according to guideline, hospital anxiety and depression score. No clinically, or statistically significant differences were found between intervention and control with respect to all parameters or in anxiety and depression levels. Statin and aspirin use improved throughout the course of the study in both groups. Statin use showed a trend (P = 0.02) in favour of control.


Conclusion
In this study there was no clinically significant perceived benefit to patients as a result of providing them with a hypertension guideline. Patient guidelines are currently planned for many chronic illnesses. It is important to determine the utility of such interventions before scarce resources are applied to them.
