Item Incidence of Corrected QT Prolongation With Concomitant Methadone and Atypical Antipsychotics in Critically Ill Children(Allen Press, 2021) Hughes, Kaitlin M.; Thorndyke, Anne; Tillman, Emma M.; Pediatrics, School of MedicineObjective: To evaluate the safety of the combination of methadone and an atypical antipsychotic in PICU patients. Methods: This was a retrospective observational cohort pilot study in a single-center PICU in an academic children's hospital. Children 1 month to 18 years of age were included if they received methadone, were then initiated on an atypical antipsychotic (i.e., quetiapine or risperidone), and had EKG monitoring before and after medication initiation. Results: Prolongation of the corrected QT (QTc) interval occurred in 5 of the 34 included patients when an atypical antipsychotic was added to methadone. Of the 5 patients who had a prolonged QTc interval, 4 (80%) were older than 12 years and had a median weight of 91.3 kg. There were statistical differences between age and weight when comparing patients who experienced QTc prolongation, but no differences in sex, ethnicity, electrolyte deficiencies, number of additional QTc-prolonging medications, and number of additional drug-drug interactions were identified. When comparing atypical antipsychotics, 9.5% of patients receiving risperidone had a prolonged QTc interval, versus 23% of patients receiving quetiapine (p = 0.04). The net change in QTc interval after initiation of methadone was 0.19 milliseconds (IQR: -3, 15), which increased after atypical antipsychotic initiation to 4 milliseconds (IQR: -16, 15). Conclusions: Our pilot trial suggests there is no clinically significant difference in incidence of QTc prolongation with addition of atypical antipsychotics to methadone.Item Transition From Intravenous to Subcutaneous Insulin in Critically Ill Adults(SAGE, 2016-06-28) Doolin, Meagan K.; Walroth, Todd A.; Harris, Serena A.; Whitten, Jessica A.; Fritschle-Hilliard, Andrew C.; Pharmacy, Eskanazi HealthBACKGROUND: Glycemic control decreases morbidity and mortality in critically ill patients. However, limited guidance exists regarding the transition from intravenous (IV) to subcutaneous insulin therapy. A validated protocol for transition is necessary since glycemic variability, hyperglycemia, and hypoglycemia adversely impact patient outcomes. METHOD: The objective was to determine the safest and most effective method to transition critically ill adults from IV to subcutaneous insulin. This single-center, retrospective, observational study included adults admitted to the burn, medical, or surgical/trauma intensive care units from January 1, 2011, to September 30, 2014. A computer-based program provided a reflection of the patient's total daily IV insulin requirements. This information was then utilized to stratify patients into groups according to their initial dose of subcutaneous insulin as a percentage of the prior 24-hour IV requirements (group stratification: 0-49%, 50-59%, 60-69%, 70-79%, ≥80%). The primary endpoint was the percentage of blood glucose (BG) concentrations within target range (70-150 mg/dL) 48 hours following transition. RESULTS: One hundred patients with 1394 BG concentrations were included. The 50-59% group achieved the highest rate of BG concentrations in goal range (68%) (P < .001). The 0-49% group, which was the transition method utilized most often, resulted in the lowest rate of goal achievement (46%). CONCLUSIONS: This retrospective study suggests critically ill adults may be safely transitioned to 50-59% of their 24-hour IV insulin requirements. A dosing protocol will be implemented to transition to 50-70% subcutaneous insulin. Follow-up data will be reviewed to assess the protocol's safety and efficacy.
