Brief Summary

SCD is an inherited disorder of hemoglobin that affects over 100,000 Americans, most of whom live in low-resourced neighborhoods. Acute SCD complications result in 230,000 emergency department visits and $1.5 billion annually in acute-care expenditures. Prior research indicates that increased disease-specific knowledge correlates with improved clinical outcomes in SCD. Thus, targeting strategies to improve disease-specific knowledge is a high priority in the care of individuals with SCD. Significant evidence describes how educational materials, including online educational programs, can be used to increase disease-specific knowledge. In this study, the investigators will evaluate a mobile phone technology intervention based on the prior evidence that technologies can improve SCD-specific knowledge.

Detailed Description

Sickle cell disease (SCD) is an inherited blood disorder that affects over 100,000 Americans, an underserved population with low life expectancy and risk for significant and life-threatening medical complications (e.g., stroke). Adults with SCD are overwhelmingly members of socially disadvantaged groups, increasing their risk for disparities in care. Annual health expenditure for individuals with SCD in the United States is about $1.5 billion, primarily from multiple emergency room visits (230,000 visits/year) for management of acute complications. Use of disease-specific knowledge has emerged as a powerful tool to decrease health care utilization. Significant evidence has described how to increase disease-specific knowledge using educational materials, including online educational programs in individuals managing chronic diseases, including SCD. Patient knowledge and use of disease-specific information like evidence-based clinical guidelines has the potential to decrease health care utilization. In 2014, the National Heart, Lung, and Blood Institute (NHLBI) published guidelines for evidence-based management of SCD for health care providers. However, to date, no national strategy has been developed to make these guidelines patient-centered, accessible, and actionable for adults with SCD. Federal Meaningful Use regulations have recommended using health-related technologies to improve patient access to their health information to promote patient engagement. Yet, many adults with SCD are not yet fully engaged in use of health technologies because they are unsure of the best format (e.g., mobile or web-based), leading to a health care technology gap. Mobile health applications (apps) that include patient-centered care guidelines could engage and activate this population given the high use of mobile technologies, potentially closing this health technology gap and improving health outcomes.

Evaluate the feasibility and acceptability of the refined iManage in a pilot study with adults with SCD. The investigators will recruit 50 adults from the population of 250 adults with SCD at the Vanderbilt Meharry Sickle Cell Disease Center of Excellence and the ohio state university comprehensive sickle cell center for a 6-month pilot study to evaluate usability, acceptance, and usage. At the end of the study, the investigators will conduct interviews with a subset of participants to gain an in-depth understanding of usage patterns and how to sustain engagement to promote ongoing app use.

Evaluate the efficacy of the refined iManage app on SCD-specific knowledge. The investigators will test the hypothesis that the refined iManage will increase SCD-specific knowledge by measuring SCD-specific knowledge at the start and end of the 6-month pilot study. the investigators will conduct exploratory analyses of secondary outcomes including patient activation, adherence to guidelines, missed days of school/work, and self-efficacy.

Arm && Interventions

Group	Intervention	Description
mobile health application	mobile health application	Group 2 will receive continuous access to technology-based patient-centered SCD-specific guidelines using a user-driven technological platform, plus a paper booklet of the guidelines with education by a health care provider at a single visit. The mobile app will include interactive content and a fully searchable collection of the SCD-specific guidelines that are age- and health literacy-appropriate. Through the mobile app, the investigators will reinforce important points of guideline content; motivate patient engagement through quizzes and reminders; and facilitate peer support, for instance by forming teams to compete against each other to attain goals.

Primary Outcome Measures

Name	Time	Method
SCD-specific Knowledge	6 months	Knowledge about SCD. This is a questionnaire that is multiple choice and asks questions about sickle cell disease with one correct answer and 3 incorrect answers. The investigators will sum up the number of correct answers which will be reported. There were a total of 39 questions, so a maximum score of 39.; This is not a scale.

Secondary Outcome Measures

Name	Time	Method
Patient Activation Measure	6 months	PAM is a measure from insignia health that measures patient activation
Usage and Usability of the mHealth Application	6 months	How often app and functionality was used. Usability will be measured by the widely used and validated System Usability Scale as described in Brooke J. SUS-A quick and dirty usability scale. Usability evaluation in industry. 1996;189(194):4-7. The mobile health application for the guidelines has built-in tracking of the number of times the application is launched, how many times each of the functions are used, and how many times each button has been pushed. To measure usage, the investigators will record the numbers of each of these events for each participant. In addition to total use, the investigators will measure usage over time including any use, initial use, periodic use, and sustained use.; SUS scale is 0-100, higher score is better. Scale has no subscales and measures usability of the app
Healthcare Utilization (ER Visits and Hospitalizations)	6 months	The investigators will measure a count of the # ER visits and # of hospitalizations (i.e., # ER visits + # hospitalizations)
Self-efficacy	6 months	sickle cell self-efficacy scale, as described in Edwards R, Telfair J, Cecil H, Lenoci J. Reliability and validity of a self-efficacy instrument specific to sickle cell disease. Behav Res Ther. 2000;38(9):951-63.; Scale is 0-45, higher score is better Scale has no subscales and measures self-efficacy
