Healthcare professionals should be concerned about the safety of the patients in their care and the references to patient safety go back as far as the Hippocratic Oath. Study of literature however shows that medical errors are still of concern and the majority of medical errors are medication errors. The aim of the study was to determine whether process changes introduced reduced both the medication prescribing and medication administration errors in the intensive care unit, thereby contributing to an increase in overall patient safety in the intensive care unit. This study retrospectively analysed the effect of the process changes on medication prescribing and administration errors. The research objectives were to: Identify the number and type of prescribing medication errors prior to the implementation of process changes; Identify the number and type of administration medication errors prior to the implementation of process changes; Identify the process changes implemented; o Determine number and type of prescribing medication errors post the implementation of process changes; Determine number and type of administration medication errors post the implementation of process changes; Assess whether the process changes affected the number and type of prescribing medication errors; and o Assess whether the process changes affected the number and type of administration medication errors. In the Phase One (1 November 2013 to 31 January 2014) 534 patient prescription charts for 172 patients were examined. Medication error rates of 57.6% (n=99) of individual patients reviewed and 18.4% of total patient prescription charts reviewed were found. A total of 69 medication prescribing errors were found in Phase One. This equates to an error percentage of 12.9% per patient chart reviewed and 40.1% per patient reviewed. Thirty medication administration errors were identified in Phase One of the study representing 17.4% of patients reviewed and 5.6% of patient prescription charts reviewed. Medication administration errors included both errors of commission, incorrect doses administered, (n=19) and omission, dose missed, (n=11). Process changes were then introduced and the results of these changes analysed in Phase Two (1 April 2014 to 31 December 2014) show an overall reduction in total medication errors with relation to number of patients reviewed from 57.6% in Phase One to 40.5% in Phase Two. In relation to number of prescription charts reviewed the medication error rate in Phase One was 18.4% and in Phase Two 14.4%. Prescribing errors in relation to number of patients reviewed reduced from 40.1% in Phase One to 26.19% in Phase Two. Overall reductions in percentage of errors were seen in all categories of prescribing errors except duplication of therapy which showed a slight increase. Based on the number of patients reviewed a reduction of prescribing errors was seen in the following categories: transcription errors (13.3% to 7.6%), anticoagulant not prescribed when indicated (3.5% to 2.4%), medication safety (5.2% to 2.9%), dose errors (9.3% to 6.6%) and duration of therapy (6.3% to 3.6%). An increase in the duplication of therapy error rate was seen (2.3% to 3.1%). There was also a reduction in administration errors in relation to number of patients reviewed with a total number of errors of 17.4% in Phase One and 15.8% in Phase Two. The number of prescribing errors per medication chart in Phase Two showed a statistically significant reduction (p=.002). A statistically significant reduction was also seen when the number of errors per patient was reviewed (p=.008). The total number of medication administration errors per medication chart showed a significant reduction (p=.042) as did the number of administration errors per patient (p=.003). When combining the total number of medication errors (both prescriobing and administration) a significant reduction was seen for both the number of charts reviewed (p=.001) and the number of patients reviewed (p=.002). These results indicate that the desired goal of increasing patient safety with regard to medication errors has been achieved but ongoing study is required to ensure the sustainability of the process changes.
