Innovative Care of Older Adults With Chronic Heart Failure (I-COACH): A Comparative Effectiveness Clinical Trial

An estimated 6.5 million adults in the U.S. have Heart Failure (HF) and the prevalence is increasing. HF is characterized by poor quality of life but this is amenable to self-management. However, the amount of support available from providers to help manage complications is far beyond what is feasible. The complex needs of these patients require a new vision for delivery of health care services, such as an mHealth management model. mHealth technologies such as blue-tooth enabled BP, heart rate, weight, and pulse oximetry remote monitoring permit sharing of immediate biometric data and video messages with providers and instantaneous feedback to patients before symptom crises, that is, when and where patients need it.

This is a single-blinded comparative effectiveness randomized controlled trial conducted in a real-world setting. A sample of 400 dyads, that is older patients with HF (>55 years) and their caregivers, will be recruited from a large medical center and randomly assigned to one of two arms: 200 dyads to a provider-directed model or 200 dyads to the mHealth management model. The provider-directed management model is the current care standard for patients with HF; care delivery consists of office and emergency visits, with telephone or in person communications. The standard of care will be augmented by providing home equipment kits with weight scale, blood pressure, pulse oximetry devices and a Log to record data. The mHealth care management model consists of real time bio-monitoring kits and telemedicine visits using a secure wireless gateway with a cloud-based clinician portal connected to a Bluetooth-paired Android Tablet. Daily readings are transmitted to a 24-hour RN call center and triaged per protocols. Outcomes informed a prior by community stakeholders to be most important at the patient, caregiver, and health systems-levels will be collected and compared at baseline, 3- and 6- months: 1) For the patient: self-care of HF; confidence and self-efficacy to manage care, symptoms, medications and treatments; HF knowledge; mental and physical health, health distress, informational support, equipment usability, and quality of life. 2) For the caregiver: caregiver burden and health. 3) For the Health System: patient satisfaction, hospital, emergency & provider visits, and mortality. Differential benefits for subsets of participants will be evaluated according to patient characteristics (socio-demographical, rurality, etc.). Evaluation of mediation variables will enhance our understanding of underlying processes. This research has the potential to revolutionize care for high-cost and high-need patients such as those with HF.

Non-connected home vital sign equipment will be given to patients in this group. The patients in the group will be instructed to record their daily readings on a paper log provided by the research team. These monitoring devices will not transmit readings to a centralized location and no one will be alerted to out-of-range readings or compliance with taking daily vital sign measures. At the front page of the log, normal ranges will be described with brief instructions about what participants/caregivers should do if their readings are out-of-range. Logs will be collected at baseline, 3-months and 6-months.

Connected home vital sign equipment (mHealth) will be given to patients in this group. The patients will be instructed to take their daily readings, which will automatically be sent to the secure cloud-based software. If the readings are out-of-range, the Registered Nurse (RN) Call Center will be automatically alerted and the event will be triaged. Daily measures and medical follow-up from the measures will be counted and collected at baseline, 3-months, and 6-months.

The PI will be supplementing standard care by providing and training each patient in the use of an analog (not internet connected) vital sign kit for 6 months: weight scale, blood pressure cuff, pulse oximeter. A Log for recording their vital sign measures.

The PI will provide each patient with weight scale, blood pressure cuff, & pulse oximeter kit connected to a Bluetooth-paired Android Health Tablet for 6 months. Daily vital sign readings will be sent to the secure cloud-based software. If the readings are out-of-range, the Registered Nurse Call Center will be automatically alerted and triaged.

questionnaire that assesses self care where higher scores mean better self-care factor correlations range from 0.25 to 0.76

subscale of questionnaire that measures anxiety. Scoring for this PROMIS instrument uses Item Response Theory (IRT), a family of statistical models that link individual items to a presumed underlying trait or concept represented by all items in the item bank. Score of 50 on any domain is the average. Greater than 50 likely represents somewhat sicker people than the general population. Min/max range is 39.1-82.7

subscale of questionnaire that measures depression. Scoring for this PROMIS instrument uses Item Response Theory (IRT), a family of statistical models that link individual items to a presumed underlying trait or concept represented by all items in the item bank.
