Computerized Dose Range Checking Using Hard and Soft Stop Alerts Reduces Prescribing Errors in a Pediatric Intensive Care Unit

OBJECTIVES: The purpose of this study was to assess the rate of prescribing errors, resulting adverse events, and patient outcomes associated with sedation and analgesia in the pediatric intensive care unit (PICU) before and during a national shortage of fentanyl and injectable benzodiazepines. METHODS: A retrospective chart review was performed of patients admitted to the PICU with at least 1 prescribed order for a sedative or analgesic agent during the time periods of January to February of 2011 and 2012. Initial orders for sedative and analgesic agents were identified and investigated for appropriateness of dose and were assessed for error-associated adverse events. Orders were stratified by timing in regard to clinical pharmacist on-site availability. Demographic and outcome information, including unintended extubations, ventilator days, and PICU length of stay, were gathered. RESULTS: One hundred sixty-nine orders representing 72 patients and 179 orders representing 75 patients in 2011 and 2012, respectively, were included in analysis. No differences were found in the rate of prescribing errors in 2011 and 2012 (33 errors in 169 orders vs. 39 errors in 179 orders, respectively, p=0.603). No differences were found in rates of prescribing errors in regard to clinical pharmacist on-site availability. A significant increase was seen in unintended extubations per 100 ventilator days, with 0.15 in 2011 vs. 1.13 in 2012, respectively (p<0.001). A significant decrease was seen in ventilator days per patient (p<0.001) and PICU length of stay per patient (p=0.019). CONCLUSIONS: There were no differences in rates of prescribing errors before versus during the fentanyl and benzodiazepine shortage.

Abstract Background: Prolonged treatment with analgesic and sedative drugs in Pediatric Intensive Care Unit (PICU) may lead to undesirable effects as dependence and tolerance. Moreover, during the analgosedation weaning patients may develop clinical signs of withdrawal, known as withdrawal syndrome (WS). Some studies indicated that dexmedetomidine, a selective α2-adrenoceptors agonist, may be useful to prevent WS, but no clear evidences still support this data. Aims of the present study are to evaluate the efficacy of dexmedetomidine in reducing the occurrence of WS during the analgosedation weaning, to evaluate its safety, to identify its optimal dose-range and to quantify its ability in reducing time of weaning, time of mechanical ventilation and PICU-stay. Methods: We will perform a prospective, multicenter, randomized, double-blind, placebo-controlled study. Patients meeting the inclusion criteria will be randomly assigned to treatment A (dexmedetomidine) or treatment B (placebo). Treatments will be started 24 hours before the analgosedation-weaning and will be continued throughout the whole weaning time. Efficacy of treatments will be evaluated by monitoring the signs of WS using the withdrawal assessment tool version 1 score (WAT-1). If WAT-1 score is ≥3, dexmedetomidine/placebo-dose will be increased following a defined protocol. Thus, efficacy will be compared between treatment groups. Safety will be assessed collecting any potentially-related adverse event. Clinical or sedation characteristics will be analyzed to assess any significant association with outcome measures. The sample size assuring a power of 95% is 80 patients for each group (N total=160 patients). The study was approved by the Ethics Committee of the University-Hospital S.Orsola-Malpighi of Bologna on 22 March 2017. Discussion: The present trial will allow to clearly assess the efficacy of dexmedetomidine in reducing the occurrence of WS during the weaning of analgosedation drugs. In addition, the study will provide a unique insight into the safety profile of dexmedetomidine.
