    The accuracy of radiology speech recognition reports in a multilingual South African teaching hospital
    (BioMed Central, 2015-03) Du Toit, Jacqueline; Hattingh, Retha; Pitcher, Richard
    Background: Speech recognition (SR) technology, the process whereby spoken words are converted to digital text, has been used in radiology reporting since 1981. It was initially anticipated that SR would dominate radiology reporting, with claims of up to 99% accuracy, reduced turnaround times and significant cost savings. However, expectations have not yet been realised. The limited data available suggest SR reports have significantly higher levels of inaccuracy than traditional dictation transcription (DT) reports, as well as incurring greater aggregate costs. There has been little work on the clinical significance of such errors, however, and little is known of the impact of reporter seniority on the generation of errors, or the influence of system familiarity on reducing error rates. Furthermore, there have been conflicting findings on the accuracy of SR amongst users with English as first- and second-language respectively. Methods: The aim of the study was to compare the accuracy of SR and DT reports in a resource-limited setting. The first 300 SR and the first 300 DT reports generated during March 2010 were retrieved from the hospital’s PACS, and reviewed by a single observer. Text errors were identified, and then classified as either clinically significant or insignificant based on their potential impact on patient management. In addition, a follow-up analysis was conducted exactly 4 years later. Results: Of the original 300 SR reports analysed, 25.6% contained errors, with 9.6% being clinically significant. Only 9.3% of the DT reports contained errors, 2.3% having potential clinical impact. Both the overall difference in SR and DT error rates, and the difference in ‘clinically significant’ error rates (9.6% vs. 2.3%) were statistically significant. In the follow-up study, the overall SR error rate was strikingly similar at 24.3%, 6% being clinically significant. Radiologists with second-language English were more likely to generate reports containing errors, but level of seniority had no bearing. Conclusion: SR technology consistently increased inaccuracies in Tygerberg Hospital (TBH) radiology reports, thereby potentially compromising patient care. Awareness of increased error rates in SR reports, particularly amongst those transcribing in a second-language, is important for effective implementation of SR in a multilingual healthcare environment.

    The scope of bullying among nurses in a public hospital in the Free State : a mixed-method study
    (Stellenbosch : Stellenbosch University, 2013-03) Du Toit, Jacqueline; De Wet, M.; Stellenbosch University. Faculty of Economic and Management Sciences. Dept. of Industrial Psychology.
    ENGLISH ABSTRACT: Orientation: Bullying is a form of counterproductive behaviour that is more subtle and more difficult to detect and that can be instigated by either individual or organisational antecedents. Research purpose: This study aims to explore bullying in a public hospital, and strives to contribute to the body of knowledge by providing guidance not only to organisational practitioners but also to employees to assist with the formation of policies and procedures to protect employees against bullying. Motivation for the study: Bullying is currently a substantial phenomenon in schools, and little research exists in South Africa that explains the extent of bullying within organisations. The focus of the study is to explore the possible antecedents and cost of bullying within a public hospital and to provide guidelines for the prevention of bullying behaviour. Research design, approach and method: The design followed was that of a mixed-method study. First, a quantitative approach was used whereby questionnaires were distributed to 77 participants. The questionnaire consisted of five sections, namely demographic particulars, prevalence of bullying and intervention against bullying, types of bullying, Negative Acts Questionnaire and Work Harassment Scale, and the cost of bullying. Data was then analysed by means of descriptive statistics to determine the sample group with the highest prevalence of bullying. The second approach was a qualitative approach that included conducting an in-depth interview with seven participants who volunteered to be interviewed. Main findings: The results represented and discussed suggest that bullying is prevalent in the public hospital in the Free State, and that some of the most prevalent behaviours are that of interrupting someone while they are speaking, belittling someone’s opinion, excessive monitoring of work, or flaunting one’s status or authority. Antecedents such as attitude, job environment, perception, power and language have been identified as possible causes for bullying behaviour. Whereas anxiety, not looking forward to going to work and constantly feeling tired are some of the psychological cost, a high frequency of sick leave indicated the organisational cost of bullying. Practical/managerial implications: Participants suggested the following interventions that can be implemented by the organisation to possibly prevent bullying behaviour: an orientation programme; a policy on how to interact with staff; complying with the language policy; creating a grievance policy; support groups and training with a specific focus on anger management; emotional intelligence, and coping skills. Contribution: While bullying is prevalent and actively combated elsewhere in the world and in local schools, the importance and consequences thereof should still be realised in South African organisations. This study examined the prevalence of bullying in a public hospital, and the possible antecedents of bullying behaviour, the cost of such behaviours that should be considered by the organisation, and possible interventions that could be implemented. In line with the literature, South African organisations can benefit from realising the importance and implementation thereof.
