- Description
- Professional nurses perform liberation of ventilated patients in the critical care units to ensure that ventilated patients can breathe on their own to maintain adequate oxygenation after the removal of an artificial airway and prevent liberation failure. The study aimed to describe the effect of an educational intervention on professional nurses’ knowledge concerning the liberation of ventilated adult patients in public critical care units. The research study described how an educational intervention increased the knowledge of professional nurses working in five public adult critical care units with a total of 54 beds for medical and surgical adult patients who are mechanically ventilated across the Eastern Cape Province. The objectives were first; to investigate the knowledge of professional nurses, concerning the liberation of ventilated adult patients. Secondly, to implement the evidence-based guidelines on liberation using an educational intervention. Thirdly, to describe the effect of an educational intervention on professional nurses’ knowledge concerning the liberation of ventilated adult patients in five public critical care units across the Eastern Cape Province. The researcher conducted an intervention research study using a quantitative, quasi-experimental pre-test/post-test with a control group design. The researcher recruited 150 participants who were professional nurses working in the five adult critical care units in academic hospitals. The five public adult critical care units were purposively divided into three sample groups, which consisted of two experimental groups and a control group. While considering the geographical location and proximity of the academic hospitals the groups were divided into Experimental Group 1 (comprised of 57 professional nurses from two critical care units) and Experimental Group 2 (comprised of 59 professional nurses from two critical care units), plus a Control Group (comprised of 34 professional nurses from one critical care unit). To achieve a large sample, all the professional nurses working in the five academic hospitals across the Eastern Cape Province were included in this study. The research study was conducted in three phases. In Phase One of the study, a pre-test questionnaire was administered to the professional nurses to investigate their current knowledge of the liberation of ventilated adult patients. Subsequently, in Phase Two, an educational intervention that was based on the liberation of ventilated adult patients used a PowerPoint in-service presentation in the form of a formal lecture, printed copies of the evidence-based guidelines on liberation and colour printed posters attached to the notice boards and strategic places such as the tea room and corridor of the critical care units in Experimental Group 1. Equally, Experimental Group 2 received only printed copies of the evidence-based guidelines. In the Control Group, the researcher did not implement the evidence-based guidelines. Three months after the implementation of the evidence-based guidelines, Phase Three was conducted, and a post-test questionnaire was administered to describe the effect of the educational intervention on the professional nurses’ knowledge. With the assistance of the statistician, data were analysed through descriptive analysis using the measure of frequency, central tendency, dispersion/variation and position. In addition to that, an inferential analysis used Analysis of Variance, Chi-square test, t-statistic (t-test), Cohen’s d, Cramér’s V, and Scheffe’s post-hoc test. Since there was no existing questionnaire, the researcher developed the questionnaires that were used in this study. The researcher ensured reliability and validity throughout the study. The ethical clearance reference number, H17-HEA-NUR-019 was obtained for the study from the Nelson Mandela University. A letter of permission was granted by the Provincial’s Department of Health, Bhisho, the Eastern Cape Province, with reference number, EC_201712_017. Other ethical principles were taking into consideration. The implementation of evidence-based guidelines on liberation using an educational intervention in the form of PowerPoint presentation, complemented with printed copies of the evidence-based guidelines and coloured posters as reminders showed an increase (Mean = 65,22; S.D = 12,08) in the mean knowledge score of professional nurses in Experimental Group 1. Contrary, the use of printed copies of the evidence-based guidelines on liberation showed a significant decrease (Mean = 53,41; S.D = 15,44; p = 0.033; Cohen's d = 0.49 small effect) in the mean knowledge score of professional nurses in Experimental Group 2. A single educational intervention method did not affect knowledge increase compared to a combined educational intervention method. Imparting knowledge in the public critical care units across the Eastern Cape Province is still very important. Further recommendations for practice, research and education were provided.
