Registration Number
NCT01610817
Lead Sponsor
Hospices Civils de Lyon
Brief Summary

Adverse drug events (ADEs) are responsible for 3.6% of the hospitalisations in France. 50% of these ADEs could be preventable. Cardiovascular drugs are frequently involved in ADEs. A common underlying factor of such events is inadequate communication between patients and medical personnel. General practitioners (GP) often initiate the treatment of hypertension, being generally the first prescribers of these medications. 12.6% of the patients present an ADE with hypertensive drug after 3 months. The InPAct procedure is a tool to facilitate communication in order to improve patient safety in primary care. In the context of the primary care prescription of an antihypertensive drug, the GP informs the patient about hypertension, cardiovascular risk, and the benefits and risks of antihypertensive drugs, which helps the patient to detect and declare situations involving a heightened risk of antihypertensive-related ADEs. The aim of the InPAct study is to evaluate the efficiency of the InPAct intervention in primary care.

Detailed Description

A stepped wedge cluster randomized study, with 8 clusters and 5 periods of 3 months each. Each cluster is composed of about ten general practitioners. The InPAct intervention will not be presented to the first patients recruited by each general practitioner, whereas it will be presented to all their last patients. The period of intervention introduction by each general practitioner will be randomized amongst the 5 periods.

Primary Outcome Measures
NameTimeMethod
The proportion of patients on antihypertensive drug reporting themselves at least one Adverse Drug Event (ADE) to their general practitioner during their 90 days of follow up.During the study : 19 months

Symptoms could have begun before patient inclusion in the study, but symptoms have to be related to an ADE and reported during the 90 days of patient follow up.

Secondary Outcome Measures
NameTimeMethod
A mean score of patient satisfaction regarding the communication and information on drug prescription and management of hypertension by the general practitioner, during the 90 days of patient follow up.During the study : 19 months
The proportion of patients on antihypertensive drug with at least an ADE detected (reported by the patient himself, or not) during their 90 days of follow up.During the study : 19 months

Symptoms could have begun before patient inclusion in the study, but symptoms have to be related to an ADE during the 90 days of patient follow up.

The proportion of patients on antihypertensive drug presenting at least one situation of risk for ADE during the 90 days of patient follow up.During the study : 19 months
The proportion of patients on antihypertensive drug for whom a physician has changed or modified at least one prescription during the 90 days of patient follow up.During the study : 19 months

This modification had to be made following an ADE or a situation of risk for ADE associated with taking an anti-hypertensive drug or a drug associated with antihypertensive treatment.

The proportion of patients who developed at least one complication following an ADE detected during the 90 days of patient follow up.During the study : 19 months
A mean score of patient skill in health after 90 days of follow-up, including a score of patient knowledge on cardiovascular risk and on the benefits and risks of antihypertensive drugs, and a score of patient skill in situation of ADE.During the study : 19 months
