title: Incidence and costs of adverse drug reactions in a tertiary care pediatric intensive care unit.
abstract: Adverse drug reactions (ADRs) increase morbidity, mortality, and hospital costs in children treated in the Pediatric Intensive Care Unit (PICU). Few studies have reported the incidence and risk factors of ADRs in PICU. Our study aimed to evaluate incidence, risk factors, and economic burden of ADRs in PICU. An intensive ADR surveillance was conducted at the PICU of Children's Hospital of Michigan between November 1, 2010 and May 31, 2011. A trigger list was used to screen for suspected ADR cases. Of the 697 consecutive PICU admissions reviewed, 13.1% experienced at least one episode of ADR. The ADR incidence was 22% in patients with cardiovascular (CV) surgery and 11.5% in other patients. The most frequently detected ADR was electrolyte imbalance associated with diuretic exposure. Mean age at admission was 4 years (interquartile range: 9 months-13 years). Risk factors for ADR included young age (<1 year), Pediatric Risk of Mortality (PRISM) score upon admission ≥3, and administration of ≥16 medications. ADRs increased total ICU costs by 3.5-fold and length of ICU stay by 3.8-fold. Increased ADR surveillance of high risk patients in conjunction with early intervention may reduce drug related morbidity and costs in the PICU.
