Engaging end-users in intervention research study design

Abstract

ABSTRACTObjective: Coordinated Healthcare Interventions for Childhood Asthma Gaps in Outcomes (CHICAGO) Plan is a 3-arm multicenter pragmatic trial to evaluate asthma interventions in high-risk Chicago children presenting to emergency departments (ED) with asthma. A formative evaluation with end-users to provide input into the trial design and outcome instruments was conducted prior to trial initiation. Methods: A multi-level data gathering framework from the field of design and standard qualitative methods was employed. This included one focus group with asthma Community Health Workers (N = 8), two focus groups with caregivers of children with asthma (N = 9), in-home interviews with caregivers (N = 9), key informant interviews at six EDs and outpatient clinical sites (N = 19), and ED tours and observations (N = 6). Data were presented, discussed, and organized into themes. Results: Data indicated that changes to the study design and discharge tool were warranted. A key insight was that ED discharge protocols typically place patient education at a single inopportune time, as families are preparing to leave the ED. At this point in time, families are less receptive to education due to fatigue and a desire to expedite the discharge process. The trial design was modified to reposition the discharge asthma plan to occur at earlier “teachable moments.” Delivery of the asthma discharge plan was assigned to study-employed ED coordinators instead of ED providers and staff. Other potential challenges to study recruitment and implementation were raised and addressed. Conclusions: Engagement of end-users in the design phase of implementation research is critical to improve research feasibility and relevance.
