ObjectivesAlthough medication reconciliation has become standard during hospital admission, rates of unintentional medication discrepancies during intensive care of pediatric patients with chronic disease are unknown. Such discrepancies are an important cause of adverse drug events in adults with chronic illness and are associated with unintentional discontinuation of chronic medications. We sought to determine the rate, type, timing, and predictors of potentially harmful unintentional medication discrepancies in children and young adults with chronic disease.DesignProspective observational cohort study.SettingPatients discharged from the intensive and intermediate care units at a tertiary care children's hospital from September 2013 to May 2014.PatientsConsecutive sample of 308 patients less than 25 years old with chronic disease defined by prescription of at least one predetermined class of chronic medication prior to hospitalization.Measurements And Main ResultsThe number of unintentional medication discrepancies with the potential for harm, as well as patient and medication-related factors predisposing patients to these errors were assessed. Two thousand seven hundred thirty-nine medication discrepancies were identified; 284 (10%) were unintentional and had the potential for harm (0.9/patient). Of these, 128 (45%) were due to errors in taking the preadmission medication history, whereas 156 (55%) were due to errors reconciling the medication history with orders. Most events occurred at admission (66%) and were dosing errors (45%). In multivariable negative binomial regression analyses (adjusted rate ratios [95% CI]), each additional preadmission medication (1.07 [1.04-1.10]), chronic respiratory medications (1.51 [1.01-2.28]), and chronic noninvasive ventilation (1.53 [1.07-2.19]) were associated with increased risk of a discrepancy.ConclusionsUnintentional medication discrepancies with the potential for harm are common among children and young adults with chronic disease during critical care admission due to both failure to obtain an accurate medication history and errors in reconciling the history with patient orders. The use of current medication reconciliation processes is insufficient to prevent errors in this high-risk population.
