Effect modification
RECRUITMENT
Previously described variables of medical complexity, health literacy, and attitudes towards medication management will be assessed at the patient- and parent-level, where appropriate, to quantitatively evaluate intervention effect modification. To qualitatively evaluate effect modification, we will conduct a semi-structured interviews through the study period with a total of 40 caregivers. Qualitative interviews will include 10 caregivers from each subgroup (technology dependent/independent and high/low health literacy); only caregivers who participated in the pMTM intervention arm will be included. To recruit for this portion of the study, participating parents will receive a $25 gift card. A trained professional qualitative study team member will conduct recorded 1-h parent interviews via phone or video software. Qualitative interview guides will be pilot tested prior to use with study subjects. The guide will elicit parents’ perceptions of the feasibility, acceptability, and barriers/facilitators of the pMTM intervention, specifically focusing on how outcomes may have been impacted by their health literacy and whether their child was dependent on specific forms of technology. Recruitment for qualitative caregiver interviews will discontinue if ongoing analysis (described below) reveals thematic saturation [
