Self-Management for Youth and Families Living With SCD - SMYLS

An interventional study of Voice Crisis Alert V2 in Sickle Cell Disease, sponsored by Medical University of South Carolina. Completed at 1 site in United States. Open to participants aged 8 Years to 17 Years. Per ClinicalTrials.gov, last updated 2020-11-19.

Study summary

The purpose of this proposal is to integrate family-centered self-management strategies with mobile health (mHealth) technology to improve reach, self-management behaviors, and child and caregiver physical and psychosocial symptoms and quality of life. Specifically, the investigators propose to conduct feasibility testing of SMYLS, which has been adapted based on user feedback in the first phase of this study. First the investigators will work with the Medical University of South Carolina (MUSC) Pediatric Sickle Cell Clinic to identify and recruit families with children with sickle cell disease (SCD) in the community, statewide. Next, the investigators will test the feasibility of the intervention with 30 dyads of children ages 8 - 17 with sickle cell disease and their parent or primary caregiver, (N=60)

What researchers measure

Primary outcomes

  1. Rates of Recruitment

    Number of weeks required to recruit 30 participants.

    Time frame: Assessed each week over a period of 6 months, cumulative data up to 6 months is reported.

  2. Participant Adherence to Intervention

    Number of participants who used the intervention (mHealth application) from baseline to mid-intervention, from mid-intervention to end-of-intervention, and from end-of-intervention to follow-up, assessed by number of participants who logged into and used the app, stored in the app's back end database.

    Time frame: baseline to 6 weeks, 6 weeks to 12 weeks, 12 weeks to 6 months

  3. Acceptability of Intervention

    Number of participants reporting problems with the intervention (mHealth app) per week.

    Time frame: Assessed each week over a period of 6 months, cumulative data up to 6 months is reported.

  4. Participant Adherence to Intervention

    number of participants who accessed the educational component of intervention, assessed using back end app use database

    Time frame: baseline to 6 weeks, 6 weeks to 12 weeks, 12 weeks to 6 months

  5. Participant Adherence to Intervention

    Number of participants who accessed the symptom monitoring component of the intervention, assessed using the app back end database

    Time frame: baseline to 6 weeks, 6 weeks to 12 weeks, 12 weeks to 6 months

Secondary outcomes

  1. Difference in Mean Pain Score Rating From Baseline to End-of-intervention

    Patient Reported Outcome Measurement Information System (PROMIS) Pain Interference Pediatric Short Form 8a: Change in score at 12 weeks minus baseline. Raw scores range from 0 - 32, with 0 being the lowest pain rating and 32 the highest pain rating. Any decrease in mean difference between scores = improved

    Time frame: baseline, 12 weeks

  2. Difference in Mean Caregiver Self-efficacy Score From Baseline to End-of-intervention

    Self-efficacy for Managing Chronic Disease 6-item scale. Scores for each item range from 1 - 10 with 1 indicating lower confidence/self-efficacy and 10 indicating higher confidence/self-efficacy. Scores for each item are averaged for the mean total score. Change in score at 12 weeks minus baseline. Any increase in difference in mean scores = improved

    Patient Reported Outcome Measurement Information System (PROMIS) Pain Intensity Pediatric 3a. Raw scores range from 3 - 15, with 3 being the lowest pain intensity rating and 15 being the highest pain intensity rating. Change in score at 12 weeks minus baseline. Any decrease in mean difference between scores = improved

    Time frame: baseline, 12 weeks

  8. Differences in Mean Scores for Disease-related Quality of Life From Baseline to End-of-intervention

    Pediatric Quality of Life Inventory (Peds QL) with SCD module: Scores are transformed on a scale from 0 - 100, with 0 indicating the highest possible problems with quality of life and 100 indicating the lowest possible problems with quality of life. Change in score at 12 weeks minus baseline. Any increase in difference between mean scores = improved

    Time frame: baseline, 12 weeks

  9. Clinic Appointment Attendance

    Number of missed clinic appointments at baseline compared to 12 weeks

    Time frame: 12 weeks

  10. Home Medication Administration

    Adherence to home medications, measured by number of medications marked as taken in the app database.

    Time frame: 12 weeks

Results

Posted Apr 16, 2020
Limitations and caveats
Limitations of this feasibility study included technical difficulties with the app, leading to an inability to accurately assess medication adherence data and measurement issues with the clinic appointment attendance. We were unable to assess these additional outcome measures with accuracy.
