Personalized Activated Technology with Heart Failure Disease Specific Functionality

Abstract

Background: Optimization of health care delivery in different settings with the goal of improving quality of life and reduction of heart failure (HF) morbidity continues to be an unmet need. Digital engagement between patients and providers is becoming more prevalent for care coordination and management of heart failure.Aims: To design and test a customized and interactive heart failure disease specific functionality with activated technology (Amazon's Echo Dot or an Avatar) as a tool for management of HF patients at home. To identify the effect of a voice activated technology in the reduction of heart failure hospitalizations, improvement of medication adherence, improvement in health-related quality of life and increase in comfort with voice activated technologies. Methods We compared two types of conversational agent technologies to standard of care, using speech recognition, to evaluate patient engagement in HF patients. The first technologyutilized the Amazon Echo Dot Alexa technology and only communicated with the patient through audio and the second was an application on a tablet using an Avatar, combining audio and visual. The conversational agent asks the HF patients a series of 11 questions, divided into three components: compliance (questions 1-3), mild HF symptoms (questions 4-6) and moderate/severe HF symptoms (questions 7-11). Participants completed questions regarding their use and comfort with technology. Inclusion criteria: admitted or treated for HF;18 or older; and resides with access to wifi. Exclusion criteria: heart transplant or ventricular assist device recipients. Participants were monitored for three months.Results: Thirty patients were enrolled in each intervention arm of the two studies with the Alexa or Avatar. Mean age was 54 years in the Alexa group and 56 years in the Avatar group. There were predominately males 61% and 63%, Alexa and Avatar, respectively. In the Alexa and Avatar groups race was predominately black, 64% and 63% followed by white 21% and 30%. The Alexa group was statistically more likely to complete the three compliance factors of weight checking (p=.030), salt monitoring (p=0.016) and medication adherence (p=0.005). Initial results suggest that older people and individuals using the smart phone answer the questionnaire at higher rates, and individuals taking an increased number of medications to treat HF had lower participation.Conclusion: Voice enabled, internet connected devices are poised to have profound impacts on the quality of life for in-home, independent, and assisted-living patients by vastly increasing the connectivity to healthcare providers.
