Study Details

Study Description

Brief Summary

The CARE-HK in HF is a registry study based on the hypothesis that adherence to guidelines is associated with improved real-world outcomes for heart failure (HF) patients. For the purpose of this study, adherence to guidelines is defined as 1) adherence to potassium (sK+) monitoring recommendations, and 2) adherence to renin-angiotensin-aldosterone system inhibitor (RAASi) treatment recommendations, according to the most current local guidelines at the time of assessment.

The study aims to evaluate real-world RAASi treatment patterns in clinical practice compared with the guideline-directed medical therapy (GDMT) recommendations. Factors associated with patients achieving GDMT will be evaluated to identify potential barriers.

Condition or DiseaseIntervention/TreatmentPhase

    Detailed Description

    The study will have a 24-month enrolment period, followed by a 24-month follow-up period, resulting in a total study duration of 48 months.

    At enrolment, relevant patient data will be retrospectively extracted from medical records for the 24 months prior to enrolment or since the time of HF diagnosis, as appropriate. After enrollment all patients will have between 24 months and 48 months of prospective follow-up.

    There are no visits or procedures associated with the study, patients will follow routine clinical care, which may include in-person and/or virtual visits. The study protocol does not recommend the use of any specific treatments and no study medication is provided as part of participation. The nature and heterogeneity of HF means patients will be treated with different treatments over the course of the study, and at the discretion of their treating physician.

    Patient data will be collected from patient records and/or during a routine clinical visit. This will include treatments prescribed, routine assessments and measurements collected at routine clinical visits, as well as hospitalisations and other relevant patient data.

    Arms and Interventions

    Single Cohort

    Patient data will be collected from patient records and/or during a routine clinical visit. This will include treatments prescribed, routine assessments and measurements collected at routine clinical visits, as well as hospitalisations and other relevant patient data.

    Outcome Measures

    Primary Outcome Measures

    1. Percentage of patients by RAASi optimisation overall [at 24-months following enrolment]

    2. Percentage of patients by RAASi optimisation following hyperkalaemic events [at 6-month intervals after a hyperkalaemic event]

    3. Comparison of percentage of patients with RAASi treatment optimisation between patiromer treated and untreated patients following hyperkalaemic events [at 24-months following enrolment]

    Secondary Outcome Measures

    1. Occurrence and incidence of hyperkalaemia events by RAASi treatment optimisation [at 24-months following enrolment]

    2. Description of physician provided reasons for treatment decisions at initiation or modification/discontinuation of RAASi treatment [up to 48 months following enrolment]

    3. Description and change of disease status measured by patient reported outcome (PRO) by RAASi treatment optimisation [at enrolment and at approximately 6-months intervals]
