Extraction and mapping of drug names from free text to a standardized nomenclature.
Free text fields are often used to store clinical drug data in electronic health records. The use of free text facilitates rapid data entry by the clinician. Errors in spelling, abbreviations, and jargon, however, limit the utility of these data. ⋯ Overall sensitivity and specificity for the validation set were 92.2% and 95.7% respectively. The mains sources of error were misspellings and unknown but valid drug names. These preliminary results demonstrate that free text clinical drug data can be efficiently extracted and mapped to a controlled drug nomenclature.

Using term frequency to identify trends in the media's coverage of health.
This poster describes a method of analyzing news reports to detect emerging trends in the media's coverage of health. The method examines term frequency and term usage in overall and health-specific news coverage. Term frequency calculation and analysis algorithms have been implemented in SalientNews, a news aggregation and analysis system. By using term frequency, SalientNews is now able to assist in the identification and analysis of emerging trends in the media's coverage of health.

The effect of implementing computerized provider order entry on medication prescribing errors in an emergency department.
Medication errors are a major concern in the Emergency Department (ED). We examined medication prescribing errors among consecutive adult ED patients during two 10-day periods before and during one 9-day period after implementing computerized provider order entry in an adult ED. 2,073 patients had 5,950, orders. Before (after) implementation there were 3.7 (2.8) potential adverse drug events, 222.0 (21.0) medication prescribing errors, and 5.1 (0) rule violations per 100 orders.

Predicting ambulance diversion in an adult Emergency Department using a Gaussian process.
When the Emergency Department (ED) reaches a critical level of overcrowding, it diverts ambulances to other hospitals. We evaluated the accuracy of a Gaussian process for prediction of ambulance diversion using March 1, 2005 November 30, 2005 data. The area under the receiver operating curve (AUC) for 120 minutes in advance was 0.93 (SE: 0.19). The instrument demonstrated a high AUC and may be used to alert ED managers earlier of a diversion episode.

Migrating toward a next-generation clinical decision support application: the BJC HealthCare experience.
The next-generation model outlined in the AMIA Roadmap for National Action on Clinical Decision Support (CDS) is aimed to optimize the effectiveness of CDS interventions, and to achieve widespread adoption. BJC HealthCare re-engineered its existing CDS system in alignment with the AMIA roadmap and plans to use it for guidance on further enhancements. ⋯ Rules were separated from execution code and made customizable for multi-facility deployment. Those changes resulted in system improvement in the short term while aligning with long-term strategic objectives.
