Advanced Practice Nurse Intervention Versus Usual Care for Hypertension 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. The patients will be recruited during their visit at the day hospitalization of the Diagnosis and Therapeutic Center of Hôtel-Dieu University Hospital, for hypertension-related complications and cardiovascular risk assessment as part of their hypertension management. Randomization/allocation will be conducted at the last moment before scheduling appointments. The "usual care" group will keep a traditional follow-up: day hospitalization then consultation with a MD within approximately 2 to 12 months. The "intervention" group will meet the APN between the day hospitalization and the MD consultation, within 1 to 6 months (Figure 1). All data will be collected on site, none remotely. All information required by the protocol will be recorded on a case report form. An explanation will be provided for each missing data. The data will be collected as it is obtained and clearly transcribed into the case report form. The primary outcome measure will be analyzed using a chi-square test. A p value \<0.05 will be considered significant. Participants with missing data for this primary outcome will be considered lost to follow-up. For secondary outcome measures, a chi-square test will be used for qualitative variables compared between the two groups. A paired t-tests will be used for the differences of rate of controlled blood pressure between day hospitalization and MD consultation in each group. Non-adherent participants (APN intervention missed for the interventional group) will be considered in the statistical analysis and the rate of non-adherent participants will be mentioned in the results.Correlations between the realization and the quality of home BP monitoring in MD consultation and controlled BP will also be analyzed. No interim analyses are scheduled.
