The Accuracy of the Pediatric Appendicitis Score in Establishing the Diagnosis of Acute Appendicitis in Children at the Adam Malik Hajj Center General Hospital Medan
Introduction
Acute appendicitis is a common cause of sudden abdominal pain in children, affecting a significant percentage of pediatric patients worldwide. In Indonesia, acute appendicitis ranks fourth among the most common causes of abdominal pain in children, with an incident rate of 1-8% of all children who visit the Emergency Unit with complaints of abdominal pain. Early and accurate diagnosis of acute appendicitis is crucial to prevent complications, deaths, and excessive medical expenses. To aid doctors in diagnosing acute appendicitis in children faster and more accurately, several score systems have been introduced, including the Pediatric Appendicitis Score (PAS). This study aims to evaluate the accuracy of the PAS in diagnosing acute appendicitis in children at the Adam Malik Hajj Center General Hospital Medan.
Background
Acute appendicitis is a medical emergency that requires prompt diagnosis and treatment to prevent complications and deaths. The diagnosis of acute appendicitis in children can be challenging, especially in primary health facilities where imaging devices such as ultrasonography, appendicograms, and CT scans are not available. The Pediatric Appendicitis Score (PAS) is a clinical scoring system that has been introduced to aid doctors in diagnosing acute appendicitis in children. The PAS is based on a combination of clinical symptoms and signs, including abdominal pain, fever, leukocytosis, and tenderness.
Methodology
This study used a cohort design, taking a sampling of pediatric patients at the Adam Malik Hajj Center General Hospital Medan who came with complaints of abdominal pain and were suspected of appendicitis. The study involved 23 children, with 18 diagnosed with acute appendicitis (study group) and 5 not diagnosed with acute appendicitis (control group). Participants who experienced abdominal pain for more than 72 hours, had a history of appendix surgery, could not speak, were uncooperative, or had other infections were excluded from the study. Data was analyzed using the Chi-Square test and T test.
Results
The analysis results showed that the PAS value > 6 had a significant incidence of acute appendicitis compared to the PAS value < 6 (p = 0.04). The PAS value > 6 had a sensitivity of 85.71%, specificity of 40%, and accuracy of 86.95% in diagnosing acute appendicitis in children. In addition, the PAS value > 9 significantly had a higher incidence of acute complicated acute appendicitis (p = 0.009).
Discussion
The results of this study showed that the PAS was quite accurate in diagnosing acute appendicitis in children, with a sensitivity of 85.71%, specificity of 40%, and accuracy of 86.95%. The PAS can be recommended as an acute appendicitis diagnosis tool in children, especially in primary health facilities where imaging devices are not available. The PAS value > 9 indicates a higher risk of acute complicated acute appendicitis, which is an important consideration in the diagnosis and treatment of acute appendicitis in children.
Conclusion
This study provides valuable information about the use of PAS in diagnosing acute appendicitis in children. The results of this study suggest that the PAS is a useful tool in diagnosing acute appendicitis in children, especially in primary health facilities where imaging devices are not available. Further research with a larger number of samples is needed to ensure this result and explore the potential use of PAS in different clinical arrangements.

Based on the results of this study, the following recommendations are made:
- The PAS can be recommended as an acute appendicitis diagnosis tool in children, especially in primary health facilities where imaging devices are not available.
- Further research with a larger number of samples is needed to ensure the accuracy of the PAS and explore its potential use in different clinical arrangements.
- The PAS value > 9 should be considered as an indicator of a higher risk of acute complicated acute appendicitis, which is an important consideration in the diagnosis and treatment of acute appendicitis in children.
Limitations
This study has several limitations, including:
- The sample size was small, with only 23 children participating in the study.
- The study was conducted in a single hospital, which may limit the generalizability of the results.
- The study did not control for other factors that may affect the diagnosis of acute appendicitis in children, such as the presence of other medical conditions or the use of medications.
Future Directions
Future studies should aim to:
- Increase the sample size to ensure the accuracy of the PAS and explore its potential use in different clinical arrangements.
- Conduct the study in multiple hospitals to increase the generalizability of the results.
- Control for other factors that may affect the diagnosis of acute appendicitis in children, such as the presence of other medical conditions or the use of medications.

Frequently Asked Questions (FAQs) about the Pediatric Appendicitis Score (PAS)
Q: What is the Pediatric Appendicitis Score (PAS)?
A: The Pediatric Appendicitis Score (PAS) is a clinical scoring system used to aid doctors in diagnosing acute appendicitis in children. It is based on a combination of clinical symptoms and signs, including abdominal pain, fever, leukocytosis, and tenderness.
Q: How is the PAS calculated?
A: The PAS is calculated by assigning points to each of the following symptoms and signs:
- Abdominal pain: 2 points
- Fever: 1 point
- Leukocytosis: 1 point
- Tenderness: 1 point
The total score is then calculated by adding up the points for each symptom and sign.
