Impact of Advanced Practical Nursing Intervention Versus Usual Care on Hypertension Control

Impact of Advanced Practical Nursing Intervention Versus Usual Care on Hypertension Control: Study Protocol for an Open-label Randomized Controlled Trial

Hypertension is the most frequent chronic pathology in France and in the world. It is one of the main modifiable cardiovascular risk factors. In France, 50% of treated hypertensives are uncontrolled and only 30% of treated patients are fully adherent to their antihypertensive treatment. Poor adherence to drug treatments is considered as one of the main causes of non-control of hypertension.

Since 2018, a new profession has entered the French healthcare system: Advanced Practice Nurses (APN). They have many broad skills, at the interface of nursing and medical exercises.

The purpose of this interventional study is to assess the impact of APN on blood pressure (BP) control in the context of usual care of hypertension thanks to a better adhesion of patients and a better therapeutic alliance.

The hypothesis formulated is that an individual APN intervention, included in a usual hypertension management, improves BP control.

This study will be a prospective, open-label, randomized 1-to-1 and monocentric trial, conducted at the Diagnosis and Therapeutic Center of the Hôtel-Dieu University Hospital, Assistance Publique - Hôpitaux de Paris, France.

Recruitment will be conducted during the ambulatory hospitalization. After the signature of the consent form, the randomization will be conducted during the ambulatory hospitalization. All recruited patients will be randomized.

According to the randomization, the odd-numbered participants will constitute the "usual care" group, and the even-numbered patients will constitute the "intervention" group.

The "usual care" group will keep a traditional follow-up: ambulatory hospitalization then consultation with a MD within approximately 2 to 12 months.

The "intervention" group will meet the APN between the ambulatory hospitalization and the MD consultation, within 1 to 6 months.

The participants will get their study appointment(s) (MD consultation +/- APN intervention) at the end of the ambulatory hospitalization according to their allocation.
