BackgroundCardiac rehabilitation (CR) improves outcomes for patients with ischemic heart disease or heart failure but is underused. New strategies to improve access to and engagement in CR are needed. There is considerable interest in technology-facilitated home CR. However, little is known about patient acceptance and use of mobile technology for CR.ObjectiveThe aim of this study was to develop a mobile app for technology-facilitated home CR and seek to determine its usability.MethodsWe recruited patients eligible for CR who had access to a mobile phone, tablet, or computer with Internet access. The mobile app includes physical activity goal setting, logs for tracking physical activity and health metrics (eg, weight, blood pressure, and mood), health education, reminders, and feedback. Study staff demonstrated the mobile app to participants in person and then observed participants completing prespecified tasks with the mobile app. Participants completed the System Usability Scale (SUS, 0-100), rated likelihood to use the mobile app (0-100), questionnaires on mobile app use, and participated in a semistructured interview. The Unified Theory of Acceptance and Use of Technology and the Theory of Planned Behavior informed the analysis. On the basis of participant feedback, we made iterative revisions to the mobile app between users.ResultsWe conducted usability testing in 13 participants. The first version of the mobile app was used by the first 5 participants, and revised versions were used by the final 8 participants. From the first version to revised versions, task completion success rate improved from 44% (11/25 tasks) to 78% (31/40 tasks; P=.05), SUS improved from 54 to 76 (P=.04; scale 0-100, with 100 being the best usability), and self-reported likelihood of use remained high at 76 and 87 (P=.30; scale 0-100, with 100 being the highest likelihood). In interviews, patients expressed interest in tracking health measures (“I think it’ll be good to track my exercise and to see what I’m doing”), a desire for introductory training (“Initially, training with a technical person, instead of me relying on myself”), and an expectation for sharing data with providers (“It would also be helpful to share with my doctor, it just being a matter of clicking a button and sharing it with my doctor”).ConclusionsWith participant feedback and iterative revisions, we significantly improved the usability of a mobile app for CR. Patient expectations for using a mobile app for CR include tracking health metrics, introductory training, and sharing data with providers. Iterative mixed-method evaluation may be useful for improving the usability of health technology.
BACKGROUND: Patient-centered counseling to help women achieve their reproductive goals is an essential yet often absent component of primary care. OBJECTIVE: We developed and piloted MyPath, a novel web-based decision support tool integrating reproductive goals assessment, information about optimizing health before pregnancy, and contraceptive decision support, for use prior to primary care visits in the Veterans Administration (VA). DESIGN: We created MyPath using best practices for decision tool development, including a conceptual framework informed by theory and user-centered design with input from patients, providers, and scientific experts. We conducted a non-randomized pilot in two VA Women's Health primary care clinics. A control group (n = 28) was recruited prior to and intervention group (n = 30) recruited after introduction of MyPath into clinics. PARTICIPANTS: Women Veterans ages 18-44 with an upcoming visit scheduled with one of eight providers. INTERVENTIONS: After recruitment of controls, providers and staff received a brief introduction to MyPath. Patients scheduled to see providers in the intervention phase used MyPath on an iPad in the waiting room prior to their visit. MAIN MEASURES: Acceptability, feasibility, discussions about pregnancy and/or contraceptive needs, and contraceptive decision quality by a survey of participants and providers. KEY RESULTS: Nearly all participants who used MyPath reported they learned new information (97%) and would recommend it to other Veterans (93%). No providers reported that MyPath significantly increased workload. A greater proportion of intervention participants reported having discussions about reproductive needs in their visit compared to controls (93% vs 68%; p = 0.02). Intervention participants also experienced greater increases in pre-/ post-visit knowledge and communication self-efficacy and a trend towards greater reduction in contraceptive decision conflict compared to controls. CONCLUSIONS: MyPath was highly acceptable to women, increased the proportion of primary care visits addressing reproductive needs, and improved decision quality without increasing providers' perceived workload. A larger randomized evaluation of effectiveness is warranted.
Objectives: Women experiencing early pregnancy loss (EPL) frequently present to the emergency department (ED), but little is known about who receives EPL care in these settings. We aimed to estimate the proportion of ED visits for EPL-related care and determine characteristics associated with seeking care for EPL in the ED in a national sample. Methods:We conducted a secondary analysis of the 2006-2016 National Hospital Ambulatory Medical Care Survey (NHAMCS), a nationally representative survey of US ED visits. We identified women ages 15-44 years who presented to the ED for threatened or confirmed EPL based on diagnosis code or chief complaint. We estimated the proportion of ED visits attributable to EPL-related care among all ED visits and among women 15-44 years old. Using multivariable logistic regression, we evaluated patient and visit characteristics associated with receiving EPL-related care versus all other care. Results:The 2006-2016 NHAMCS dataset included 325,037 visits (weighted n = 1,447,144,423), including 82,871 visits among women ages 15-44 years (weighted n = 371,016,125). Of all ED visits for women ages 15-44 years, 2.7% (95% confidence interval, 2.5-2.9) were for EPL-related care. This equates to ≈900,000 visits annually.Compared with women ages 15-44 years presenting to the ED for other reasons, those presenting for EPL-related care were younger and more likely to be Black or Hispanic.Conclusions: EPL-related care accounts for over 900,000 ED visits in the United States each year. These findings highlight the current burden of EPL visits upon EDs nationally.

[1][2][3][4] Individuals experiencing EPL may report bleeding, cramping, or no symptoms at all, and many who do experience symptoms of EPL will go on to have a normal pregnancy. 2 Although some individuals present to their primary obstetric providers for evaluation of EPL, many seek care in the emergency department owing to lack of an established provider, delays in accessing outpatient care and timing or urgency of symptoms. 5,6
