Laboratory stewardship perceptions and testing patterns at a pediatric tertiary care center.

BACKGROUND: Despite stewardship efforts, laboratory testing overuse persists across medicine. OBJECTIVES: To understand laboratory stewardship perceptions and testing patterns at a tertiary care pediatric hospital so that we could identify potential improvement opportunities. METHODS: An electronic survey exploring laboratory stewardship was sent to all pediatric medicine resident and staff physicians. Laboratory testing data were also assessed for patterns of testing and overuse. RESULTS: The survey response rate was 54% (43/80). The results indicated good familiarity with stewardship but poor familiarity with testing specifics (eg, cost). A mobile reference application was the most preferred quality improvement intervention, and online modules were the least desired. Overuse was apparent, with as many as 53% of laboratory tests being repeated within 7 days and only half of repeated tests subsequently yielding abnormal results. CONCLUSIONS: Altogether, the data we collated demonstrated poor understanding of laboratory stewardship and substantial repeat testing with few abnormal results. These study findings suggest that laboratory stewardship is lacking at our center, and that multiple improvement opportunities exist.

Adolescents' Cannabis Knowledge and Risk Perception: A Systematic Review.

To systematically review evidence evaluating cannabis-related knowledge and perception of risk in children and adolescents. We systematically searched Medline, PsycINFO, and EMBASE using Preferred Reporting Items for Systematic Reviews and Meta-Analyses methodology. 133 studies from around the world (including ages 10-18 yrs) met inclusion criteria, with 70% meeting grade 2C quality. Increased knowledge and perception of risk of cannabis frequently correlated with lower levels of current use and intent to use. Studies examining correlations over time generally demonstrated increased adolescent cannabis use and decreased perception of risk. Included prevention-based interventions often enhanced knowledge and/or perception of risk in adolescents exposed to the intervention. Studies exploring outcomes relating to legislative changes for recreational marijuana use demonstrated considerable heterogeneity regarding knowledge and perception of risk whereas studies that focused on medicinal marijuana legislative changes overwhelmingly demonstrated a decrease in perception of risk post legalization. Increased knowledge and perception of risk of cannabis in adolescents often correlate with lower levels of current use and intention to use in the future. Further study and implementation of public health and clinically-oriented strategies that seek to increase knowledge among youth about the potential health harms of cannabis use should continue and be prioritized.

Atypical Immunoglobulin A Vasculitis in a Pediatric Patient With Ulcerative Colitis.

Rates of pediatric inflammatory bowel disease and biologic therapy use continue to rise. Consequently, specialists and generalists should recognize potential complications and side effects. We report the unique case of an adolescent with ulcerative colitis (UC) on vedolizumab presenting with severe abdominal pain, hematochezia, and subsequent purpura. After extensive investigation and a complex clinical course, diagnosis of atypical immunoglobulin A vasculitis was made. This is the first pediatric case of vasculitis in a patient with UC on vedolizumab and only the second reported case overall in UC. This case illustrates the emerging diagnostic challenge of distinguishing inflammatory bowel disease treatment complications from other common pediatric conditions.
