Introduction :
A high degree of standards in operating the Reverse Osmosis (RO) system and maintaining a high quality water treatment is essential to prevent chemical, bacterial and endotoxin contaminants from causing health threats to the patients. Renal dialysis assistants (RDA) are responsible for the performing water treatment in the hemodialysis center. Numerous RO educational videos could be found for nursing education. Nonetheless, standardized videos that meet the RDA’s needs and for local use were not found.
Objectives :
This project aimed at developing a video training program in addition to the traditional teaching method (standardized guidelines in the operation and maintenance of RO water quality). This served to empower RDA in both knowledge and skills related to water treatment system. The findings can inform subsequent RDA trainings that extend to various procedures and skills in the unit.
Methodology :
A one-group pretest-posttest design was employed in the present project. All RDAs in KWH Renal Centre were recruited. Video demonstrations of four procedures were provided with step-by-step explanations. Baseline knowledge of RDA were collected the training program and these were evaluated immediately upon completion of the program. The test involves 10 practical questions and 10 related knowledge questions about the 4 procedures, all in the format of multiple choice questions. A 7-items satisfactory survey was also completed to offer information on the usefulness of the video.
Result & Outcome :
Nine RDA were recruited. Wilcoxon signed rank test showed statistically significant result in the pre- and post- knowledge test (p=.05) and the post test score increased by 20.7%. The RDA’s performance achieved a passing rate of 100%. Also, the participant reported highly positive response to the use of video training in the satisfactory survey. The scores ranged from 4.88 to 5.89 (6-point Likert scale). The results suggested the video training of the RO system to the RDA were well received and had a positive impact to their competence.
