Abstract:

Objective: To compare possible differences in the proportion of medication errors associated with high-risk medications that were avoided by the use of automated infusion device (AID) technology in pediatric and adult intensive care unit (ICU) patients. A secondary purpose was to investigate the number of serious adverse drug events (ADEs) identified by root-cause analyses (RCA).Method: The study included pediatric and adult patients receiving high-risk medications by continuous infusion in an academic medical center with mixed medical-surgical ICUs. A retrospective evaluation of 1 year's data collected prospectively in an AID database was used to compare the proportion of medication errors avoided based on reprogramming events (2.5 times limit as a low threshold) and overrides (10 times limit as high). Information obtained from RCAs was used to compare the proportion of serious ADEs that occurred during the 5-year periods before and after AID implementation.Results: The pediatric population was 1.68 times (95% confidence interval [CI], 1.18 to 2.38) more likely to require a reprogramming event than the adult acute care population for all high-risk medications combined. Significantly more reprogramming events occurred in the pediatric patients with potassium (relative risk [RR], 2.77; 95% CI, 1.15 to 6.68) and insulin (RR, 2.73; 95% CI, 1.15 to 6.45) infusions. Additionally, there were more overrides in the pediatric compared to the adult population for the high-risk medications (RR, 1.82; 95% CI, 1.32 to 2.53). The number of serious adverse or sentinel events as identified in RCAs decreased from six before (four deemed preventable by AID technology) to three (zero preventable) after AID implementation.Conclusions: This study demonstrates that AID technology when properly used leads to reductions in medication errors and possibly serious ADEs in critically ill patients receiving high-risk medications. The technology appears to be particularly beneficial in pediatric patients with weight-based dosing strategies. However, the potential for clinicians to override the alerts remains a concern. © 2010 Thomas Land Publishers, Inc.

PMID: 10485509;Abstract:

The purpose of this economic analysis was to develop an economic model using intra-institutional cost data for acute, oliguric renal insufficiency treated with either an albumin-furosemide complex or albumin followed by furosemide (sequential therapy). The perspective of this study was from the standpoint of the institution (University Medical Center, a teaching hospital). The decision tree and sensitivity analyses demonstrated that the albumin-furosemide complex would be more effective and less costly than sequential therapy for a range of outcome probabilities. Using effectiveness assumptions from published literature, the complex could avoid dialysis in 27% of patients compared with 8% of patients receiving sequential therapy. The complex would also be less costly ($7778 vs $8748). In terms of cost- effectiveness, the complex is $28,807 per averted dialysis compared with $109,350 for sequential therapy.
