Clinical Trial Summary

The investigators conducted a national two-arm, randomized controlled trial of caregivers of individuals with DS to assess the efficacy of DSC2U in assuring adherence to evidence-based guidelines. The research plan was approved by the Partners Human Research Committee.

Description:

Background: The overwhelming majority of people with Down syndrome do not have access to specialty clinics, a disparity resulting in delayed or missed diagnoses and significant untreated co-morbidities. To meet this critical gap in needs, the investigators created "Down Syndrome Clinic to You" (DSC2U), a novel, web-based tool created for caregivers of individuals with Down syndrome, which generates personalized recommendations for the caregiver and the patient's primary care provider (PCP).

Methods: In a national, randomized controlled trial of 230 caregivers who had children or dependents with Down syndrome without access to a Down syndrome specialist, 117 were randomized to receive DSC2U and 113 to receive usual-care. The primary outcome was adherence to five health evaluations indicated by national guidelines for Down syndrome: celiac screen, sleep study, thyroid test, audiogram, and ophthalmology evaluation.

Eligibility

Potential eligible participants were directed to the study website (www.dsc2u.org) for the eligibility screening questionnaire in English and Spanish and online consent. After selecting a language preference (English or Spanish), in addition to questions about the child's or dependent's biological sex, race and ethnicity, the eligibility screening questions included:

1. Do you have a child or dependent with DS?

2. Is your child or dependent 1 year or older?

3. When is your child's next annual well visit ("PCP visit")?

4. Does your child or dependent currently receive care at a DS specialty clinic? (If the child or dependent was actively followed in a DS specialty clinic, even one out of state. For example, a family from Arizona who travels to Texas each year for their child to be seen in a DS specialty clinic would be ineligible)

Inclusion Criteria:

• If you have a child or dependent with Down syndrome (DS)

• If your child or dependent is 1 year or older

• If your child or dependent is does not receive care at a DS specialty clinic

Exclusion Criteria:

• If your child or dependent does receive care at a DS specialty clinic

• If your child or dependent is under 1 year old

• If your child or dependent has a PCP that is already involved in the study

DS occurs naturally and proportionally in all races and ethnicities, so the study's population estimates were proportional to the racial/ethnic distribution of the U.S. population, as reported in the 2010 U.S. Census. To achieve commensurate representation in the study, the investigators applied a quota system in offering enrollment using the race and ethnicity of the individual with DS (not the caregiver).

The investigators' plan was to enroll participants such that there were: no more than 144 white individuals with DS, no fewer than 25 Hispanic or Latino/Latina individuals with DS, and no fewer than 20 black individuals with DS. The team also planned to enroll no more than 120 individuals with DS of one sex.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Number of Participants With Indicated Evaluations That Were Completed or Recommended by the PCP	Adherence to the five health evaluations indicated by national guidelines for Down syndrome. The five health evaluations included: celiac screen, sleep study, thyroid test, audiogram, and ophthalmology evaluation.	7 months after the participant's scheduled PCP visit
Secondary	Questionnaire: Caregiver Experience With the Intervention	Measure the caregiver experience with the PCP using a 10-point Likert scale with "10" representing "most helpful" and "0" representing "least helpful." This questionnaire was only distributed to those in the Intervention arm because it assessed their experience with the Intervention itself.	2 weeks and 7 months after their scheduled PCP visit and with the intervention
Secondary	Quality of Life Outcomes for Person With Down Syndrome: 2-week Follow-up	PedsQL 4.0 parent-proxy and PedsQL 2.0 Family Impact Module (https://www.pedsql.org/) were used to assess for qualify of life for people with Down syndrome and their caregivers. Here we report the change from baseline on the subdomains of these assessments. The subdomains on PedsQL 4.0 parent proxy were Psychosocial and Physical. The subdomains on the Family Impact Module (FIM) were Parental and Family scores. For both instruments we also report the total/summary scores. PedsQL scoring instructions were used. These are all scaled from 0 (Low) to 100 (High). Higher scores indicate a better quality of life. Baseline: (Mean±SD); Change: (Mean±SE)	Change from baseline at the 2-week follow-up time point
Secondary	Quality of Life Outcomes for Person With Down Syndrome: 7-month Follow-up	PedsQL 4.0 parent-proxy and PedsQL 2.0 Family Impact Module (https://www.pedsql.org/) were used to assess for qualify of life for people with Down syndrome and their caregivers. Here we report the change from baseline on the subdomains of these assessments. The subdomains on PedsQL 4.0 parent proxy were Psychosocial and Physical. The subdomains on the Family Impact Module (FIM) were Parental and Family scores. For both instruments we also report the total/summary scores. PedsQL scoring instructions were used. These are all scaled from 0 (Low) to 100 (High). Higher scores indicate a better quality of life. Baseline: (Mean±SD); Change: (Mean±SE)	7-month follow-up survey
Secondary	PCP Experience With the Intervention (Down Syndrome Clinic to You)	These measurements were gathered by self-administered mail survey to the PCPs who had patients participating in the Intervention Group. A total of 94 PCPs who had patients in the Intervention Arm responded to this question: "Did [name]'s caregiver give you a copy of the primary care plan before and/or during the wellness visit?" (Note: this survey was not mailed to the PCPs who had patients participating in the Control group as the survey was a measure of experience with the Intervention itself.)	2 weeks after the scheduled PCP visit
