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.

Thesis (Master of Nursing)--Cape Peninsula University of Technology, 2019 / One of the most important issues in the provision of healthcare services which threaten the patient's safety, is medication administration errors. These could compromise patient safety and may lead to patient disability or even death, besides the financial cost of these errors. Nurses are responsible for administering medication to numerous patients. They thus are the last defence line against medication administration errors. All student nurses are trained very early in their courses on how to administer medication and all the complications and implications that accompany this important procedure. Although lecturers spend time and effort in teaching nursing students about protocols for safe medication administration, nurses still commit medication administration errors. The aim of the study was to determine awareness and perception of the occurrence and reporting of medication administration errors (MAEs) among nursing students. A descriptive quantitative design was employed. A questionnaire was used to collect data. Responses were collected from 291 nursing students at a higher education institution in the Western Cape, South Africa. Nonprobability proportional quota sampling was used in this study for data collection. Data was analysed with IBM SPSS® software. Data was presented in graphs, percentages, means, and standard deviation, while inferential statistics were conducted. The findings of the study reveal that 85.2% of the respondents were aware of MAE occurrence, but 40.1% were unaware of reporting of these errors. The top and most significant subscale for MAE occurrence was the physician communication subscale, while the top and only significant barrier to reporting these errors was the fear subscale. In conclusion, most of the respondents were aware of MAE occurrence, while more than a third were unaware of the reporting of these errors. The study recommended building non-punitive blame-free reporting systems to emphasise the importance of reporting errors.

This study investigated the effectiveness of utilizing acoustic measures as an objective tool in monitoring speech errors and providing visual feedback to enhance speech training and aural rehabilitation of children with hearing impairment. The first part of the study included a comprehensive description of the acoustic characteristics related to the speech deficits of a hearing impaired child. Results of a series of t-tests performed on the experimental measures showed that vowel length and the loci of formant frequencies were most relevant in differentiating between correctly and incorrectly produced vowels, while voice onset time along with measures of Moment 1 (mean) and Moment 3 (skewness) obtained from speech moment analysis, were related to consonant accuracy. These findings, especially the finding of an abnormal sound frequency distribution shown in the hearing impaired child's consonant production, suggest a link between perceptual deficits and speech production errors and provide clues to the type of compensatory feedback needed for aural rehabilitation. The second part of the study involved a multiple baseline design across behaviours with replication across three hearing impaired children to assess the efficacy of treatment with acoustic signals as visual feedback. Participants' speech articulations following traditional speech training and training using spectrographic and RMS displays as visual feedback (referred to as 'visual treatment') were compared, with traditional non-visual treatment followed by visual treatment on one or two targets in a time-staggered fashion. Although no statistically significant difference on the experimental measures was found between the two training approaches based on perceptual assessment, some objective acoustic measures revealed more subtle changes toward normal speech patterns with visual treatment as compared to a traditional approach. Further acoustic-perceptual studies with a larger sample size and longer experimental period are needed to better understand the general and long-term effectiveness of visual treatment.
