Tracking Assaultâ injured, Drugâ using Youth in Longitudinal Research: Followâ up Methods

ObjectivesViolence is one of the leading causes of death among youth ages 14 to 24. Hospitalâ and emergency department (ED)â based violence prevention programs are increasingly becoming a critical part of public health efforts; however, evaluation of prevention efforts is needed to create evidenceâ based best practices. Retention of study participants is key to evaluations, although little literature exists regarding optimizing followâ up methods for violently injured youth. This study aims to describe the methods for retention in youth violence studies and the characteristics of hardâ toâ reach participants.MethodsThe Flint Youth Injury (FYI) Study is a prospective study following a cohort of assaultâ injured, drugâ using youth recruited in an urban ED, and a comparison population of drugâ using youth seeking medical or nonâ violenceâ related injury care. Validated survey instruments were administered at baseline and four followâ up time points (6, 12, 18, and 24 months). Followâ up contacts used a variety of strategies and all attempts were coded by type and level of success. Regression analysis was used to predict contact difficulty and followâ up interview completion at 24 months.ResultsA total of 599 patients (ages 14â 24) were recruited from the ED (mean ± SD age = 20.1 ± 2.4 years, 41.2% female, 58.2% African American), with followâ up rates at 6, 12, 18, and 24 months of 85.3%, 83.7% 84.2%, and 85.3%, respectively. Participant contact efforts ranged from two to 53 times per followâ up time frame to complete a followâ up appointment, and more than 20% of appointments were completed off site at community locations (e.g., participantsâ homes, jail/prison). Participants who were younger (p < 0.05) and female (p < 0.01) were more likely to complete their 24â month followâ up interview. Participants who sought care in the ED for assault injury (p < 0.05) and had a substance use disorder (p < 0.01) at baseline required fewer contact attempts to complete their 24â month followâ up, while participants reporting a fight within the immediate 3 months before their 24â month followâ up (p < 0.01) required more intensive contact efforts.ConclusionsThe FYI study demonstrated that achieving high followâ up rates for a difficultâ toâ track, violentlyâ injured ED population is feasible through the use of established contact strategies and a variety of interview locations. Results have implications for followâ up strategies planned as part of other violence prevention studies.Peer Reviewedhttps://deepblue.lib.umich.edu/bitstream/2027.42/146571/1/acem13495_am.pdfhttps://deepblue.lib.umich.edu/bitstream/2027.42/146571/2/acem13495.pd
