The COVID-19 pandemic has resulted in significant changes to healthcare delivery for children with SCD, as they are at increased risk of severe illness from COVID-19 infection. Given their risk status, it was recommended that patients with SCD complete telehealth visits when possible. Some families also chose to delay care because they feared their child would get infected at hospitals/healthcare clinics that care for COVID-19 positive patients. Since the lives of all families enrolled in the Engage-HU trial have been affected to some extent, we incorporated measures to capture the impact of the COVID-19 pandemic and the usability of telemedicine implementation and services.
Methods: Engage-HU is a randomized control trial comparing two dissemination methods for clinicians to facilitate shared decision-making with caregivers of young children with SCD. Study outcomes include caregiver confidence in decision-making and perceptions of experiencing shared decision-making as well as HU uptake and child health outcomes. Eligible children are 0 to 5 years, candidates for HU, and their caregiver has not decided about HU in the past 3 months. The trial is being conducted at 9 sites in the United States and uses a unidirectional crossover design. The primary endpoints are caregiver decisional uncertainty and caregiver perception of shared decision-making measured using validated tools. Data will be analyzed using the intent-to-treat principle, and all participants will remain in the arm to which they were randomized. A multiple group comparison analysis will be performed to assess significant response variable differences by group randomization.
The Engage-HU study aims to recruit 174 caregivers who are considering initiating HU. The trial is being conducted at 9 sites in the United States. Data collection is ongoing, and 160 caregiver-participants have been enrolled to date. Since May 2020, caregiver-participants have completed the COVID-19 Exposure and Family Impact Scales (CEFIS), which contain 2 subscales (exposure to potentially traumatic aspects of the pandemic, impact on families), and the COVID-19 telemedicine use survey during a study visit.
Results: Currently, 8 of the 9 sites have collected data from 48 caregivers (93.8% mothers), most of whom (93.8%) identify as African American/Black (see Figure 1). Correlations indicated that older caregivers experienced greater exposure (Mean = 7.0, SD = 4.1, range = 1-19) to potentially traumatic aspects of the pandemic (r = .31, p = .04). Distress related to COVID-19 varied widely across the sample, for both caregivers (Mean = 5.9, SD = 2.9, range = 1-10) and children (Mean = 4.1, SD = 3.4, range = 1-10). Scores on the telemedicine usability survey were generally high, indicating that caregivers are happy with the quality of care delivered via telehealth. However, caregivers (r = .30, p = .09) and children (r = .32, p = .07) experiencing more pandemic-related distress reported less satisfaction with telehealth.
Conclusion: Although Engage-HU has resumed research operations, recruitment has not reached pre-pandemic targets, as fewer eligible patients are scheduled for routine care visits at SCD clinics. Our preliminary analyses suggest a significant continued impact of the pandemic on families and general satisfaction with the quality of healthcare delivered via telemedicine. These findings indicate that targeted screenings to identify and intervene for those who demonstrate more COVID-19 pandemic-related distress are needed.
