  6. 6. Background • 1.5 million patients harmed by medications in U.S. annually • Hospitalized patients at risk for medication errors • 19% of all medical errors were medication-related medication- • 400,000 preventable ADEs per year (~1 medication error / patient / year) • 78% of medical errors in ICU associated with medications • 28% of ADEs estimated to be preventable • Increased hospital length of stay, cost and mortality Bates DW.

  13. 13. Medication Errors in the ICU: Before and After BCMA Implementation • Objective • Measure the impact of BCMA on medication administration error rates in MICU • Methods • 744-bed community, teaching hospital • 38-bed MICU • Direct observation technique 13 DeYoung JL.

  16. 16. BCMA Impact on Medication Errors: ICU vs. General Ward • Objective • Measure the impact of BCMA on administration error rates in multiple patient care areas • Methods • Prospective, observational study • 386-bed academic teaching hospital • Multiple patient care areas • 2 medical-surgical wards • MICU • SICU 16 Helmons PJ. Am J Health Syst Pharm 2009;66:12021210
  17. 17. Overall and “Wrong-Time” Error Types: ICU vs. General Ward p=NS Overall • No difference in error rate p=NS (ICU or non-ICU) General Ward • Increase in “wrong-time errors” after BCMA • 58% decrease after BCMA (excluding “wrong-time”errors) ICU • No differences 17 Helmons PJ. Am J Health Syst Pharm 2009;66:12021210
  18. 18. Types of Errors Excluding “Wrong-Time”: ICU vs. General Ward General Ward • Decrease in “omission” errors (p<0.0001) • Decrease in “drugs not available” errors (p<0.05) ICU • No differences 18 Helmons PJ. Am J Health Syst Pharm 2009;66:12021210
  19. 19. Severity of Drug Administration Errors • Objective • Evaluate the severity of potential medication errors during administration phase intercepted by BCMA • Methods • 6 community hospitals • Same BCMA system • Multidisciplinary reviewing panel (n=6) • Medication Errors classified by severity • Minimal • Moderate • Severe 19 Sakowski J. Am J Health-Syst Pharm 2008;65:1661-1666 Health- 2008;65:1661-
  20. 20. Results • Overall severity • 945 total errors detected • 9% (n=81) were “Moderate” or “Severe” • “Moderate” or “Severe” errors by type • 21% “no order” • 9% “discontinued or expired order” • 4% “dose early” • 4% “wrong dose” • Errors involving “high-alert” medications • 20% = insulin, narcotics, potassium, sodium, anticoagulants • Narcotics most common of “high-alert” drugs (74%) 20 Sakowski J. Am J Health-Syst Pharm 2008;65:1661-1666 Health- 2008;65:1661-
  21. 21. Conclusion • Types of errors impacted by BCMA varied between ICU and non-ICU patient care areas • Although the clinical significance of “wrong-time” errors remains controversial, BCMA has the potential reduce other clinically important medication errors • Medication errors still occur despite BCMA suggesting the necessity for continued process improvement and further system changes to compliment this technology • Studies limited by low baseline prevalence of medication error • Dispensing and administration errors were significantly decreased with BCMA technology 21
