Introduction:
Evidence for the benefits of health information technology (HIT) in the paediatric
setting is currently limited. In 2012, electronic-prescribing, standardised
concentration infusions (SCIs) and smart-pump technology were implemented into
the paediatric critical care unit (PCCU) in Our Lady’s Children’s Hospital, Crumlin.
Aim:
To assess the impact of this new HIT on PCCU medication errors.
Methodology:
A Delphi consensus process developed a list of novel or previously unaddressed
medication errors. The results, combined with published medication errors
definitions, were applied to three further studies: a before and after study of
clinical pharmacist interventions; the direct observation of smart-pump infusions; a
retrospective review of hospital voluntary incident reports. The respective focus of
each study was prescribing errors, smart-pump-related administration errors, and
potentially severe infusion-related errors. Ethics approval was granted or waived
for each study. Data analysis and statistically tests were performed using
Microsoft Excel® and STATA® (Version 13.1).
Results:
The Delphi panel determined that 14 of 17 scenarios be included as medication
errors; reaching consensus on electronic-prescribing scenarios was most difficult.
Overall medication error rates were unchanged on implementation of electronicprescribing
(10.2% v 9.8%, p=0.99). Altered error distribution was evident.
Implementing SCIs reduced paper-based infusion errors (29% to 14.6%,
p<0.001), with a further non-significant reduction identified with electronic infusionorders
(8.4%, p>0.05). Direct observation identified medication errors in 5.4% of
infusions (n=1023). Programming errors were uncommon (1.6%). The benefits of
the pump-interface were demonstrated. Voluntary incident report review identified
more clinically significant errors (14.1% v ≤7%) than the other studies.
Technology-generated errors, and the capacity to engineer out errors with HIT
systems, were evident in all studies.
Conclusion:
The benefits of HIT in the complex PCCU setting have been demonstrated. SCIs
and smart-pumps increase the safety of paediatric infusions. Reducing overall
prescribing errors with electronic-prescribing is more difficult to achieve.
