- ItemFactors Influencing Sustained Engagement with ECG Self-Monitoring: Perspectives from Patients and Health Care Providers.(0000-00-00) Reading, Meghan; Baik, Dawon; Beauchemin, Melissa; Hickey, Kathleen T; Merrill, Jacqueline ABACKGROUND Patient generated health data PGHD collected digitally with mobile health mHealth technology has garnered recent excitement for its potential to improve precision management of chronic conditions such as atrial fibrillation AF a common cardiac arrhythmia However sustained engagement is a major barrier to collection of PGHD Little is known about barriers to sustained engagement or strategies to intervene upon engagement through application design OBJECTIVE This article investigates individual patient differences in sustained engagement among individuals with a history of AF who are self monitoring using mHealth technology METHODS This qualitative study involved patients health care providers and research coordinators previously involved in a randomized controlled trial involving electrocardiogram ECG self monitoring of AF Patients were adults with a history of AF randomized to the intervention arm of this trial who self monitored using ECG mHealth technology for 6 months Semistructured interviews and focus groups were conducted separately with health care providers and research coordinators engaged patients and unengaged patients A validated model of sustained engagement an adapted unified theory of acceptance and use of technology UTAUT guided data collection and analysis through directed content analysis RESULTS We interviewed 13 patients 7 engaged 6 unengaged 6 providers and 2 research coordinators In addition to finding differences between engaged and unengaged patients within each predictor in the adapted UTAUT model perceived ease of use perceived usefulness facilitating conditions four additional factors were identified as being related to sustained engagement in this population These are 1 internal motivation to manage health 2 relationship with health care provider 3 supportive environments and 4 feedback and guidance CONCLUSION Although it required some modification the adapted UTAUT model was useful in understanding of the parameters of sustained engagement The findings of this study provide initial requirement specifications for the design of applications that engage patients in this unique population of adults with AF
- ItemMeasuring health status and symptom burden using a web-based mHealth application in patients with heart failure.(0000-00-00) Baik, Dawon; Reading, Meghan; Jia, Haomiao; Grossman, Lisa V; Masterson Creber, RuthBACKGROUND Symptoms of heart failure markedly impair a patient s health status The aim of this study was to identify predictors of health status in a sample of racially and ethnically diverse patients with heart failure using a web based mobile health application mi Symptoms METHODS We conducted a cross sectional study at an urban academic medical center Patients with heart failure self reported symptoms using validated symptom instruments e g patient reported outcome measurement information system by way of the mobile health application mi Symptoms The primary study outcome was health status measured with the Kansas City cardiomyopathy questionnaire clinical summary score Data were analyzed using descriptive statistics and multiple linear regression RESULTS The mean age of the sample n 168 was 58 7 12 5 years 37 were women 36 were Black 36 identified as Hispanic Latino 48 were classified as New York Heart Association class III and 44 reported not having enough income to make ends meet Predictors of better health status in heart failure included higher physical function 0 89 p 0 001 and ability to participate in social roles and activities 0 58 p 0 002 and predictors of poorer health status were New York Heart Association class IV 11 68 p 0 006 and dyspnea 0 77 pUnder0 001 The predictors accounted for 73 of the variance in health status CONCLUSION Patient centered interventions should focus on modifiable risk factors that reduce dyspnea improve functional status and enhance engagement in social roles to improve the health status of patients with heart failure
- ItemA Multi-step Usability Evaluation of a Self-Management App to Support Medication Adherence in Persons Living with HIV.(0000-00-00) Beauchemin, Melissa; Gradilla, Melissa; Baik, Dawon; Cho, Hwayoung; Schnall, RebeccaPURPOSE Adherence to antiretroviral therapy is essential to HIV management and sustaining viral suppression Despite simplified regimens adherence remains difficult for certain persons living with HIV PLWH There is evidence to support the use of mHealth apps for effective self management in PLWH however a medication adherence app with real time monitoring for this population has not been developed and rigorously evaluated by PLWH We developed a mHealth app WiseApp for HIV self management to help PLWH self manage their health The purpose of this study was to evaluate the usability of the WiseApp METHODS We conducted a three step usability evaluation using 1 a traditional think aloud protocol with end users 2 a heuristic evaluation with experts in informatics and 3 a cognitive walkthrough with end users During the cognitive walkthrough we tested two devices fitness tracker and medication tracking bottle that were linked to the WiseApp RESULTS The think aloud protocol informed iterative updates to the app specifically to make it easier to see different sections of the app The heuristic evaluation confirmed the necessity of these design changes The cognitive walkthrough informed additional updates and confirmed that overall the app and the linked devices were usable for the end users CONCLUSION The results of the cognitive walkthrough with both experts and end users informed iterative refinements to the WiseApp and finalization of a mHealth app for PLWH to better self manage their health
- ItemUnderstanding the predisposing, enabling, and reinforcing factors influencing the use of a mobile-based HIV management app: A real-world usability evaluation.(0000-00-00) Cho, Hwayoung; Porras, Tiffany; Baik, Dawon; Beauchemin, Melissa; Schnall, RebeccaOBJECTIVE To conduct an in depth analysis of users experiences using an HIV self management app MATERIALS AND METHODS We conducted four follow up focus groups at the end of a 3 month randomized feasibility trial All focus group sessions were audio recorded and transcribed A thematic analysis was conducted to explore emerging themes All of the themes were categorized into three factors of the PRECEDE component of the PRECEDE PROCEED framework For a finer granularity of analysis the codes of each theme were broken into positive negative and neutral codes by study group RESULTS 36 participants including 24 from the intervention group and 12 from the control group participated in the focus group sessions A total of 14 themes organized by the PRECEDE factors were identified from focus group transcripts Five themes related to predisposing factors were 1 ease of app use 2 user friendly functionality 3 self efficacy for symptom management 4 design preference of illustrated strategies with videos and 5 user control convenience vs security Four themes related to enabling factors were 1 information needs of symptom management 2 symptom tracking 3 fit in lifestyle schedule living conditions and 4 additional languages e g Spanish Five themes related to reinforcing factors were 1 communication with healthcare providers 2 individual tailored information visualization 3 social networking 4 individual tailored information quality and 5 improvement in quality of life DISCUSSION AND CONCLUSION Usability evaluation in a real world setting enabled us to measure users actual experiences when interacting with the app during their everyday lives Our work highlights the importance of using mobile technology for persons living with HIV specifically those with low income housing instability and adds to the body of literature on the potential for implementation and dissemination of symptom self management strategies through a mobile platform
