Not Applicable

• Conditions: Hypertension; Medication Adherence
• Interventions: Behavioral: Collabree Mobile Phone Application Medication Adherence Booster (simplified version); Behavioral: Collabree Mobile Phone Application Medication Adherence Booster

• Registration Number: NCT05131074
• Lead Sponsor: Anjali Raja Beharelle

Brief Summary

This is a clinical study to improve the regularity of medication intake for high blood pressure. Adult women and men who are over 50 years old, who have received a prescription drug for high blood pressure from MediService, and who have to take at least 4 tablets per day (of which at least 1 dose of medication per day is for high blood pressure) can participate in this study.

The investigators intend to examine whether Collabree, a mobile phone application, is effective in supporting patients with hypertension to more successfully following their therapy plan in order to improve the regularity of medication intake.

The study includes a 90-day intervention phase and a 90-day follow-up. The study does not require any therapy adjustments and no visits to a study center are necessary. The participants conduct the study independently at home. Participants will also fill out questionnaires.

Participants are randomly assigned to one of 3 groups in a ratio of 1: 1: 1. Two of these groups will receive the Collabree mobile phone application.

Arm && Interventions

Group	Intervention	Description
Intervention Group B	Collabree Mobile Phone Application Medication Adherence Booster (simplified version)	Patients receive the Collabree mobile phone application with a specific set of functions.
Intervention Group A	Collabree Mobile Phone Application Medication Adherence Booster	Patients receive the Collabree mobile phone application with a specific set of functions.

Primary Outcome Measures

Name	Time	Method
Medication Adherence	90 days	Difference between intervention Group A and the control group in mean medication adherence at endpoint (i.e. the endpoint visit at 90 days) as measured by pill count.

Secondary Outcome Measures

Name	Time	Method
Self-reported medication adherence	90 days	Mean change from baseline in in-app medication adherence (defined as the number of medications self-reported as "taken" during the intervention period of 90 days divided by the number of prescribed medications listed in the in-app medication plan in that same time period) at endpoint for the intervention Group A vs. intervention Group B relative to the control group.
Medication adherence (3 group comparison)	90 days	Mean change from baseline in medication adherence (monitored by pill count) at endpoint for the intervention Group A vs. intervention Group B relative to the control group.
Self-assessed medication adherence	90 days	Mean change from baseline in the score on the Hill-Bone Scale (German version) questionnaire on medication adherence for the intervention Group A vs. intervention Group B relative to the control group at endpoint. The Hill-Bone Compliance to Blood Pressure Therapy Scale (German) scores can range from 14 to 56. A higher score means worse compliance.
