Advanced Practice Nurse Intervention Versus Usual Care For Hypertension Control: Study Protocol For An Open-Label Randomized Controlled Trial
Abstract Background: 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. Methods: The study is designed as prospective, open-label, controlled, randomized 1-to-1 and mono-centric at the Hôtel-Dieu University Hospital, Paris, France. The participants are all hypertensive and recruited during an ambulatory hospitalization (AH) for cardiovascular assessment in the context of the management of their hypertension. Patients are divided into two groups: a control group who keeps a traditional follow-up (AH then consultation with a medical doctor (MD) within approximately two to six months) and an interventional group who will see an APN between the AH and the MD consultation, within 1-3 months. Patients are followed up over six months. The main judgment criterion is BP control (BP < 135/85 mmHg in home BP measurement). The hypothesis formulated is that an individual APN intervention, included in a usual hypertension management, improves BP control. Discussion: This innovative study is a first in France where APNs are at the dawn of their establishment in the healthcare system. It will provide an objective look at this new profession and the impact it can have on the overall management of hypertension. Trial registration: This trial was registered in ClinicalTrials.gov on June 24, 2020: protocol number NCT0448249.
