Abstract
Objective: To compare the knowledge and performance of disinfection and sterilization practices among personnel in the central supply unit.
Materials and Methods: A quasi-experimental study with a before-and-after data collection design was conducted. The sample groups consisted of 24 central supply personnel and 154 ward nurses. Research tools included a coaching plan, a questionnaire on the demographics of central supply personnel, a knowledge test, a checklist for assessing practice, and a satisfaction survey. The content validity index (CVI) for these tools was 0.90, 1.00, 0.96, 0.93, 1.00, and 0.88, respectively. A knowledge test was also administered to 20 personnel whose job functions were similar to those in the sample groups, yielding a Kuder-Richardson formula 20 result of 0.83. Observations made by researchers resulted in an interrater reliability score of 1.00. The satisfaction survey from 20 ward nurses outside the study group, analyzed using Cronbach’s alpha formula, had a coefficient of reliability of 0.77. The study was conducted from January 1st to June 30th, 2022, divided into three phases, each lasting 8 weeks. Baseline data, including demographics, knowledge scores, and random observations of the practices of the central supply personnel, were collected before the intervention. The intervention, using a 4-step coaching approach, was conducted during the second phase. Knowledge scores and random observations of the practices of the central supply personnel were re-evaluated in the post-intervention phase. Satisfaction levels were randomly obtained from 154 ward nurses in the unit. Data were analyzed using descriptive statistics and were compared using paired t-tests and Pearson's chi-squared tests, respectively.
Results: Knowledge scores among central supply personnel significantly increased from 30.5 ± 2.7 to 36.9 ± 3.0 (p < 0.001). The percentage of correct practice in the disinfection and sterilization process increased from 83.17% to 99.38% (p < 0.001). The average satisfaction level was 4.02 ± 0.38 out of five.
Conclusion: Coaching can effectively promote knowledge and standard practices in disinfection and sterilization among central supply personnel.
