Insights
Digital health tools like the Corrie platform can aid recovery after acute myocardial infarction by improving self-management and adherence to treatment. This intervention shows promise in reducing readmissions for heart attack patients.
Area of Science:
- Cardiology
- Digital Health
- Health Informatics
Background:
- Unplanned readmissions post-acute myocardial infarction (AMI) significantly increase morbidity, mortality, and healthcare costs.
- Digital health interventions offer a promising avenue for enhancing patient self-management, adherence to therapies, and cardiovascular risk reduction.
- The Corrie Health Digital Platform (Corrie) is a novel digital health intervention incorporating a smartphone application, smartwatch, and blood pressure monitor.
Purpose of the Study:
- To assess the feasibility and usability of the Corrie digital health intervention in patients recovering from acute myocardial infarction.
- To evaluate the potential of Corrie as a self-management tool for improving outcomes after AMI.
- To compare the time to first readmission within 30 days post-discharge for patients using Corrie versus standard care.
Main Methods:
- The MiCORE study (Myocardial infarction, Combined-device, Recovery Enhancement) involves three phases: development, pilot testing, and a prospective research study.
- Phase 2 established the feasibility of deploying Corrie in an acute care setting with 60 AMI patients.
- Phase 3 is an ongoing prospective study enrolling AMI patients (≥18 years) with smartphones in 4 hospitals since October 2017, aiming for 140 participants.
Main Results:
- The feasibility of deploying the Corrie platform in an acute care setting was successfully established in Phase 2 among 60 patients.
- Patient enrollment for Phase 3 is ongoing, with recruitment occurring during hospitalization for eligible acute myocardial infarction patients.
- The study is actively enrolling participants across four hospitals, utilizing personal or provided devices (iPhone, Apple Watch).
Conclusions:
- Implementing digital health interventions like Corrie in acute care settings is feasible.
- The Corrie platform demonstrates potential as an effective self-management tool for patients recovering from acute myocardial infarction.
- Further research is ongoing to determine Corrie's impact on reducing readmission rates compared to standard care.
Background:
Unplanned readmissions after hospitalization for acute myocardial infarction are among the leading causes of preventable morbidity, mortality, and healthcare costs. Digital health interventions could be an effective tool in promoting self-management, adherence to guideline-directed therapy, and cardiovascular risk reduction. A digital health intervention developed at Johns Hopkins-the Corrie Health Digital Platform (Corrie)-includes the first cardiology Apple CareKit smartphone application, which is paired with an Apple Watch and iHealth Bluetooth-enabled blood pressure cuff. Corrie targets: (1) self-management of cardiac medications, (2) self-tracking of vital signs, (3) education about cardiovascular disease through articles and animated videos, and (4) care coordination that includes outpatient follow-up appointments.
Methods And Results:
The 3 phases of the MiCORE study (Myocardial infarction, Combined-device, Recovery Enhancement) include (1) the development of Corrie, (2) a pilot study to assess the usability and feasibility of Corrie, and (3) a prospective research study to primarily compare time to first readmission within 30 days postdischarge among patients with Corrie to patients in the historical standard of care comparison group. In Phase 2, the feasibility of deploying Corrie in an acute care setting was established among a sample of 60 patients with acute myocardial infarction. Phase 3 is ongoing and patients from 4 hospitals are being enrolled as early as possible during their hospital stay if they are 18 years or older, admitted with acute myocardial infarction (ST-segment-elevation myocardial infarction or type I non-ST-segment-elevation myocardial infarction), and own a smartphone. Patients are either being enrolled with their own personal devices or they are provided an iPhone and/or Apple Watch for the duration of the study. Phase 3 started in October 2017 and we aim to recruit 140 participants.
Conclusions:
This article will provide an in-depth understanding of the feasibility associated with implementing a digital health intervention in an acute care setting and the potential of Corrie as a self-management tool for acute myocardial infarction recovery.
