ABSTRACT
Background: The Early Warning Score (EWS) system has been recommended for an early identification tool of deterioration.
However, its implementation has not been optimal, one of which is due to the low level of knowledge and understanding of EWS among nurses.
Purpose: This study aimed to determine the effects of EWS tutorial simulation on nursesAo knowledge and clinical performance.
Methods: This study employed a pretest-posttest quasi-experimental design with a control group.
Purposive sampling was used to recruit samples of 42 respondents each in the intervention group and control group.
The data were collected using the questionnaires to measure knowledge and clinical performance and analyzed using Chi-square.
Wilcoxon, and Mann-Whitney tests.
Results: The results showed that there were significant differences in the pre-test and post-test of knowledge and clinical performance in both groups .
<0.
There was also a significant difference in clinical performance between the intervention group and the control group .
<0.
However, no significant difference in knowledge was found.
Conclusion: Tutorial simulation of EWS had an effect on increasing nursesAo clinical Although there was no significant difference in knowledge between the intervention group and the control group, the intervention group showed a better value than the control group.
EWS tutorial simulation can be used as one of the training methods to increase nursesAo knowledge and clinical performance in EWS.

BACKGROUND
The care needs of patients with the acute illness have increased with the complexity of existing problems.
Such conditions can trigger clinical deterioration that may develop into Serious Adverse Events (SAE.

A majority of SAEs begin with abnormal physiological changes and can develop into critical illness later (Corfield et al.

Early detection and appropriate interventions are important in improving the safety and effectiveness of care in patients with clinical signs of worsening (Alam et al.
, 2.
Early Warning Score (EWS) system is a bedside tool developed for early identification of physiological deterioration by establishing numerical values of physiological parameters in which the results can be used to see the patientAos condition.
EWS is able to predict who is at risk of critical illness (Corfield et al.
, 2.
The implementation of EWS has not been optimal so far due to several obstacles, including poor understanding of physiological deterioration and triggering criteria (De Meester.

and weak clinical reasoning skills (Lapkin.
Levett-jones, & Bellchambers, 2.
Educational programs have been developed to assist staff in recognizing and managing worsening patient conditions, but lack of studies that evaluate the effects of educational programs on knowledge and clinical performance.
The quality of nursing competence requires good performance in various nursing services.
Nurses not only require adequate knowledge and skill in carrying out their duties and responsibilities, but they need to transform it into effective performance (Zhang.

as actual performance is the most important outcome of education (Bradshaw & Hultquist, 2017.
Khan & Ramachandran, 2.
Furthermore.
Saab et al.
suggest that EWS education programs can be used to increase nurse knowledge, self-confidence, and clinical performance.
A preliminary study conducted by the researchers in one of the hospitals in Indonesia showed that the implementation of EWS was still suboptimal.
Furthermore, incorrect calculation of the EWS scores, as well as a non-standardized understanding of the EWS among nurses, were still found.
Research on EWS training with tutorial simulation to increase nursesAo knowledge and clinical performance has not been extensively Therefore, it is indeed necessary to investigate how such simulation affects nursesAo knowledge and clinical performance.
PURPOSE
The purpose of this study was to determine the effects of EWS tutorial simulation on nursesAo knowledge and clinical performance.

METHODS
Research design The present study used a pretest-posttest quasi-experimental research design with a control group.
Samples and setting This study was conducted at one hospital in Indonesia.
A purposive sampling method was utilized to recruit the samples of nurses who met the inclusion criteria: working in an adult inpatient room, never receiving EWS training, and had been working for at least two years.
Forty-two respondents who met the inclusion criteria in each of the intervention group and the control group participated in this study.
Research instrument and data collection The instruments used in this study were the knowledge questionnaire and the Rescuing a Patient in Deteriorating Situations tool (RAPIDS too.
The knowledge questionnaire consisted of respondentsAo characteristics and 20 questions related to the concept and implementation of the EWS in handling patients showing signs of deterioration.
This questionnaire was developed in accordance with the New Early Warning Score (NEWS) guidelines based on the Royal College of Physician .
and National Clinical Effectiveness Committee .
The questionnaire is a linked scale .
with a total score of 100.
The instrument used to measure clinical performance was the modified RAPIDS tool (Liaw.

, critical thinking, and clinical reasoning could be seen in the actions of nurses in following up deterioration and monitoring frequency.
Part 3 contained communication using ISBAR to see nursesAo expertise in reporting patient conditions.
Permission to use the RAPIDS tools was obtained from the instrumentAos owner (Liaw et , 2.
, for which the validity and reliability of the instrument had been carried out.
The original instrument was then translated and modified by adjusting the instrument points with the latest EWS concept, updated NEWS 2017, and consulted with expert Validity testing using expert judgment was carried out on two experts by examining the question items.
The knowledge questionnaire was tested for validity using PearsonAos product moments with computer aids.
Based on the validity test on the knowledge questionnaire, all 20 question items were valid.
The reliability test was carried out using the formula Kuder Richardson 20 (KR-.
and the instrument was reliable.
Pre-test and post-test on both groups were conducted on the same day.
All respondents both in the intervention group and the control group were separately collected in the training room to take a 20-minute knowledge and clinical performance using the Copyright A 2019.
NMJN, p-ISSN 2087-7811, e-ISSN 2406-8799 Nurse Media Journal of Nursing, 9.
, 2019, 234 knowledge questionnaires.
The EWS tutorial simulation was administered in the intervention group sequentially.
First, the EWS tutorial was given to all respondents for 90 minutes, then continued with a 60-minute case simulation.
The simulation was given to the respondents in three large groups by the researchers and two trained research The control group received the EWS tutorial training for 90 minutes without case simulations.
Data analysis Univariate and bivariate analyses were conducted in this study.
Data processed using the univariate analysis were general information on the characteristics of respondents.
Bivariate analysis was used to determine the relationship between independent and dependent variables.
Data analysis began with conducting data normality tests using Shapiro-Wilk as the number of respondents was less than 50 respondents in each group.
The results of the normality test showed that the existing data, both knowledge, and clinical performance, had an abnormal distribution.
Furthermore, the Wilcoxon test was used to see differences between the pre-test and post-test of knowledge and clinical performance within groups, while the Mann-Whitney test was used to see differences in the pre-test and post-test of knowledge and clinical performance between groups.
Ethical consideration Prior to the study, all respondents expressing agreement to participate in the study were informed of the objectives, benefits, and procedures of the research.
They were also requested to sign informed consent.
Respecting the privacy and confidentiality of respondents, providing training fairly, providing benefits, and avoiding dangerous actions were ensured during the study.
This research had been reviewed and obtained ethical permission from the ethics and research committee in the Faculty of Nursing.

DISCUSSION
Effects of EWS simulation tutorial on knowledge This study showed that pre-test knowledge was mostly in the poor category, both in the intervention group and in the control group.
In the post-test, the intervention group and control group showed an increase in the good category by 57.
1% and 19%, respectively.
There was a significant difference in the pre-test and post-test knowledge within groups, both in the intervention group and in the control group.
In contrast, there was no significant difference in the pre-test and post-test knowledge values between the intervention group and the control group.
Based on the results of this study, it can be seen that EWS tutorial simulation could increase nursesAo knowledge related to EWS, although there was no statistically significant difference in effects when compared to the control group.
It may be noted that the posttest score of knowledge in the intervention group was better than the control group.

, 2019, 238 situations can improve nursesAo knowledge and clinical performance in the inpatient room in handling clinical deterioration of patients in a simulation setting.
There are five categories of clinical competence in nurses, namely, clinical expertise, knowledge and understanding, interpersonal attributes, problem solving and clinical decisions, and technical expertise (Zhang et al.
, 2.
The interaction between knowledge and skill will encourage the realization of excellent performance (Boyatzis, 1.
The results of this study also reinforce previous research, reporting that providing education or EWS tutorial training in the control group and EWS simulation tutorial in the intervention group caused changes in the form of increased knowledge and clinical performance of nurses, especially in the handling of worsening clinical conditions of Today nurses do not only require adequate knowledge and skills in carrying out their duties and responsibilities but must be able to transform effective performance in every new situation (Lindsey & Jenkins, 2013.
Saab et al.
, 2.
The need for knowledge and good clinical performance from nurses increases along with the reality that all acute care in hospitals has now increased the number of patients with complex health problems.
In other words, there is an increase in the number of patients at risk of worsening clinical conditions, which if not handled properly and correctly, will lead to Serious Adverse Events (SAEAoS) such as cardiac arrest in hospitals, unintended ICU admissions, and unexpected deaths (Taenzer et al.
, 2.
In fact, most of SAEAoS is preceded by signs of deterioration, which is in the form of changes in vital signs (Fagan et al.
, 2.
Therefore.
SAEAos should not have happened or at least preventable occurrence rates.

CONCLUSION
The result of this study showed that there was a significant difference in nursesAo clinical performance between the intervention and the control groups after the implementation of EWS tutorial simulation.
In terms of knowledge, there was no significant difference between the groups.
This EWS simulation tutorial can be used as an optional training method to improve clinical performance among nurses.
Future studies should consider the modification of the intervention in the duration and post-test measurement for better
