Adaptation and Implementation of SBIRT for Adolescents with Chronic Medical Conditions Hospitalized in Pediatric Inpatient Units - Adolescents with a chronic medical condition (A-CMC) are more likely to misuse and initiate alcohol and other drugs (AOD) at younger ages compared to adolescents without CMCs. A-CMCs account for the majority of pediatric inpatient hospitalizations as A-CMCs are often admitted for an acute inpatient stay following an emergency department visit for an exacerbation of their disease. However, A-CMCs are not routinely screened for alcohol use in pediatric inpatient settings. Thus, the pediatric inpatient setting provides clinicians a critical, but missed, opportunity to universally screen for alcohol use among A-CMCs once medical concerns are stabilized. The current study addresses this gap in the care cascade by examining the workflow processes in an urban pediatric hospital’s inpatient units, adapting Screening, Brief Intervention, and Referral to Treatment (SBIRT) to the population and setting, and identifying SBIRT implementation strategies to pilot in a single arm hybrid type III effectiveness-implementation trial. This research is attained via three Specific Aims. In Aim 1, the candidate will observe inpatient workflows and collaborate with a Partner Steering Committee (PSC) composed of hospital staff (e.g., clinicians, administrators, information technology), A-CMCs, and parents to adapt SBIRT delivery and intervention components for the inpatient setting and population. Aim 2 will involve continued partnership with the PSC, to select, specify, and prioritize a set of SBIRT implementation strategies ideally suited for the inpatient setting and population. Aim 3 will consist of a single arm pilot hybrid type III effectiveness-implementation trial that simultaneously tests the set of implementation strategies selected in Aim 2 (primary outcome) and the SBIRT intervention adapted in Aim 1 (secondary outcome). To conduct this research, the candidate, Dr. Summersett Williams, requires training in three key areas: 1) expert knowledge and application of intermediate and advanced IS methods, including implementation strategy selection and evaluation of implementation outcomes; 2) application of human- and community-centered design methods, including intervention adaptation and usability testing; and 3) expert application of the learning health system model to improve the health of A-CMCs who engage in risky drinking through enhanced healthcare system performance. These training aims will be supported by Ann & Robert H. Lurie Children’s Hospital of Chicago and by the candidate’s mentorship team. The mentorship team will be led by Primary Mentor Dr. Sara Becker, an expert in implementing SBIRT targeting risky drinking in pediatric health settings. The proposal will also be supported by Drs. Robert Garofalo, Lisa Kuhns, and Patricia Franklin, experts in intervention adaptation, human- and community-centered design methods, and the learning health system model, respectively. Taken together, this research and career development plan will advance a significant public health issue by advancing access to evidence-based alcohol health services for a vulnerable pediatric population while launching Dr. Summersett William’s career as an independent implementation scientist.
