Background: Emergency care is typically sought for serious acute medical conditions. Longer waiting times in the emergency department not only contribute to patients' dissatisfaction with the care received but may also result in delays in diagnosis and treatment. The objectives of the study are: -

To find out how well-versed the staff nurses were in the triage system before the exam.
To assess the efficacy of a self-study module teaching staff nurses about the triage system.
To ascertain the association between demographic characteristics and pre-test knowledge.

Materials and Methods: Using a suitable sampling technique, 500 participants were selected for the evaluation, which included a one-group pre-and post-test design. Using a structured knowledge questionnaire, staff nurses were given a SIM to help them learn more about the triage system. This was done as a pre-test. The post-test was completed after the seventh day. Results: Staff nurses do not possess sufficient expertise in the triage method, according to the report. Before the implementation of SIM, the average knowledge score was 13.53; however, after its implementation, there was a significant increase, nearly doubling to 27.20. A statistically significant difference exists between the knowledge scores, with a t-value of 1.671 and a p-value less than or equal to 0.05. Analyzing the data by area reveals that triage meaning, triage system, and triage nurse have a higher mean percentage of actual gain (56.25), whereas triage techniques have a lower one (18.60).
