Impact of a Procedure for the Information and Active Participation of the Patient in the Primary Care Prescription of Antihypertensives (InPAct)

January 22, 2015 updated by: Hospices Civils de Lyon

Impact of a Procedure for the Information and Active Participation of the Patient in the Primary Care Prescription of Antihypertensives : InPAct Study (Information for Participating Actively in Cardiovascular Treatment)

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.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

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.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

Non-Probability Sample

Study Population

Hypertensive patients on anti-hypertensive medication. Patients of 85 general practitioners selected in Rhone-Alps/Auvergne and Paris region in France.

Description

Inclusion Criteria:

  • Patient monitored for essential hypertension requiring a first prescription, a renewal or a change of antihypertensive drug treatment
  • Patient with the ability to understand and express themselves in French
  • Patient accepting to communicate his phone number and accepting a telephone survey within the fourth month following its inclusion in the study.

Exclusion Criteria :

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Patients with the InPAct intervention
The InPAct intervention will be presented to the last patients recruited by each general practitioner
Other: InPAct : Information for Participating Actively in cardiovascular treatment
Educational guide presented by general practitioners to the patients. A first part of the guide contains some information on cardiovascular risk and on the benefits and risks of antihypertensive drugs. A second part of the guide consists of encouraging the patient to take an active part in monitoring of its treatment.
Patients without the InPAct intervention
The InPAct intervention will not be presented to the first patients recruited by each general practitioner

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
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.
Time Frame: 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.
During the study : 19 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
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.
Time Frame: 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.
During the study : 19 months
The proportion of patients on antihypertensive drug presenting at least one situation of risk for ADE during the 90 days of patient follow up.
Time Frame: During the study : 19 months
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.
Time Frame: 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.
During the study : 19 months
The proportion of patients who developed at least one complication following an ADE detected during the 90 days of patient follow up.
