Study information
Scientific title
Acronym
The HyDRA trial - Hypertension Decision Reinforcing Aid
Study hypothesis
High blood pressure (hypertension) is an important public health problem. There is ongoing concern that the benefits demonstrated in randomised trials of antihypertensive drug treatment are not implemented in everyday clinical practice. Community-based studies throughout the world show that blood pressure goals are achieved in only 25-40% of the patients who take antihypertensive drug treatment. A situation that has remained unchanged for the last 30 years. Observational studies have shown that inadequate control of blood pressure is associated with a significant risk of stroke.
This study aims to improve the decision aid tool and develop a web-based CDSS which will facilitate individual care of Tayside/Fife hypertensive patients, enabling health professionals to overcome the pre-specified barriers of poor chronic disease management. These include: treating to therapeutic targets; aiding in the practical complexity of treating to target for different chronic disorders (in this situation blood pressure, cholesterol, cardiovascular risk and for diabetic patients, glycaemic treatment goals); and as an aid to structuring clinical care by facilitating registration, recall and regular review and incorporating prompts for effective clinical care.

Intervention
The intervention is a computer based decision support system. It incorporates the dual elements of a health professional decision support system and patient decision aid. The key elements will include: web-based, multifaceted intervention modelled on the successful Tayside regional diabetes network (MEMO/DARTS); a health professional element including prompts/reminders; a facility for registration, recall and review of patients, flexibility so that the functions can be 'tailored' to respond to data entry; feedback (at the individual, practice and regional level).
Control: usual care
As of 02/06/2011 this trial has stopped due to a combination of poor recruitment, funding issues and relocation of the Principal Investigator from Scotland to Ireland in 2006.
