Alvarado Score

Background: RIPASA scoring has been developed to replace the disappointingly low accuracy Alvarado score in Asian population for diagnosis of acute appendicitis. Objective of present study was to compare the RIPASA and Alvarado score in Arab population and determine their accuracy when applied to our patients in Egypt and Kingdom of Saudi Arabia (KSA).Methods: By applying the RIPASA and Alvarado scores to 100 patients from KSA, 100 patients from Egypt who presented to emergency with right iliac fossa pain. The decisions for appendicectomy were based on clinical judgment only. Histopathology as gold standard was correlated with both scores. ROC curve analysis, sensitivity, specificity, positive predictive value and negative predictive value, diagnostic accuracy for RIPASA and Alvarado system were calculated using SPSS version 20.Results: On comparing both the scoring system in patients of both hospital groups, we found that sensitivity of RIPASA scoring is greater than Alvarado scoring system 95.51% and 73.03% respectively in BTH group, and 97.56% and 79.27% respectively in KASH group, while the specificity of RIPASA scoring system is less than Alvarado scoring system 72.73% and 81.82% respectively in BTH group and 66.67% and 83.33% respectively in KASH group.Conclusions: In our Arab population the RIPASA score could be applied in diagnosis of acute appendicitis with higher sensitivity, NPV and diagnostic accuracy compared to the Alvarado score.

Ripasa Score

Background: Acute appendicitis is one of the most common surgical emergencies. Various clinical scoring systems have been used for early diagnosis of acute appendicitis, of which Alvarado score is the most popular but it is found to be less accurate when applied to Asian population compared to RIPASA score. Radiological modalities such as computed tomography (CT) imaging may aid in making a definite diagnosis but will inflate the cost of treatment. This study aims to compare RIPASA and Alvarado scoring system in the diagnosis of acute appendicitis in our population.Methods: It was a comparative cross-sectional study done in 100 patients. RIPASA and Alvarado scores were applied to each patient. Our inclusion criteria were patients presenting with Right iliac fossa pain who subsequently underwent Appendicectomy in the same admission. Exclusion criteria included patients admitted under other specialties, those who underwent previous appendicectomy, elective appendicectomy and those not willing for the study.  Results: The sensitivity and specificity of RIPASA score was 95.12% and 66.67% and that of ALVARADO score was 64.63% and 77.78%. The positive predictive value (PPV) and negative predictive value (NPV) of RIPASA score was 92.86% and 75% and that of Alvarado score was 92.98% and 32.5%. The diagnostic accuracy of Alvarado and RIPASA scores were 67.0% and 90.0% respectively.Conclusions: RIPASA scoring system is more accurate and specific scoring system for our population than Alvarado in diagnosing acute appendicitis.

Ripasa Score

Acute appendicitis is the most common condition encountered in the Emergency department .Alvarado and Modied Alvarado scores are the most commonly used scoring system used for diagnosing acute appendicitis.,but its performance has been found to be poor in certain population . Hence our aim was to compare the diagnostic accuracy of RIPASA and ALVARADO Scoring system and study and compare sensitivity, specicity and predictive values of these scoring systems. The study was conducted in Government district hospital Nandyal . We enrolled 176 patients who presented with RIF pain . Both RIPASA and ALVARADO were applied to them. Final diagnosis was conrmed either by CT scan, intra operative nding or post operative HPE report. Sensitivity,specicity, positive predictive value, negative predictive value, diagnostic accuracy was calculated both for RIPASA and ALVARADO. It was found that sensitivity and specicity of the RIPASA score in our study are 98.7% and 83.3%, respectively. PPV and NPV were 98.1% and 88.2% and sensitivity and specicity of the Alvardo score in our study are 94.3% and 83.3%, respectively. PPV and NPV were 98% and 62.5%.Diagnostic accuracy of RIPASA score and Alvarado score are 97% and 93% respectively. RIPASA is a more specic and accurate scoring system in our local population when compared to ALVARADO . It reduces the number of missed appendicitis cases and also convincingly lters out the group of patients that would need a CT scan for diagnosis (score 5-7.5 ) BACKGROUND: Acute appendicitis is one of the most commonly dealt surgical emergencies, with a lifetime prevalence rate of approximately 1 one in seven. The incidence is 1.5–1.9 per 1,000 in the male and female population, and is approximately 1.4 times greater in men than in women. Despite being a common problem, it remains a difcult diagnosis to establish, particularly among the young, the elderly and females of reproductive age, where a host of other genitourinary and gynaecological inammatory conditions can present with signs and symptoms that are 2 similar to those of acute appendicitis. A delay in performing an appendectomy in order to improve its diagnostic accuracy increases the risk of appendicular perforation and peritonitis, which in turn increases morbidity and mortality. A variable combination of clinical signs and symptoms has been used together with laboratory ndings in several scoring systems proposed for suggesting the probability of Acute Appendicitis and the possible subsequent management pathway. The Raja Isteri Pengiran Anak Saleha Appendicitis (RIPASA) and ALVARADO score are new diagnostic scoring systems developed for the diagnosis of Acute Appendicitis and has been shown to have signicantly higher sensitivity, specicity and diagnostic accuracy. AIMS AND OBJECTIVES PRIMARY OBJECT 1. To compare RIPASA Scoring system and ALVARADO Scoring system in terms of diagnostic accuracy in Acute Appendicitis. 2. To study and compare sensitivity, specicity and predictive values of above scoring systems. SECONDARY OBJECT 1. To study the rate of negative appendicectomy based on above scoring systems. CONCLUSION: The RIPASA score is a simple scoring system with high sensitivity and specicity for the diagnosis of acute appendicitis. The 14 clinical parameters are all present in a good clinical history and examination and can be easily and quickly applied. Therefore, a decision on the management can be made early. Although the RIPASA score was developed for the local population of Brunei, we believe that it should be applicable to other regions. The RIPASA score presents greater Diagnostic accuracy and Sensitivity and equal specicity as a diagnostic test compared to the Alvarado score and is helpful in making appropriate therapeutic decisions. In hospitals like ours, the diagnosis of AA relies greatly on the clinical evaluation performed by surgeons. An adequate clinical scoring system would avoid diagnostic errors, maintaining a satisfactory low rate of negative appendectomies by adequate patient stratication, while limiting patient exposure to ionizing radiation, since 21 there is an increased risk of developing cancer with computed tomography, particularly for the paediatric age group.

Background: The RIPASA Score is a new diagnostic scoring system developed for the diagnosis of Acute Appendicitis which showed higher sensitivity, specificity and diagnostic accuracy compared to ALVARADO Score, particularly when applied to Asian population. Not many studies have been conducted to compare RIPASA and ALVARADO scoring systems. Hence, author want to compare prospectively Alvarado and RIPASA score by applying them to the patients attending the hospital with right iliac fossa pain that could probably be acute appendicitis.Methods: A prospective analysis of 116 cases admitted with RIF pain during a 2 years period was performed. Patients between 15-60 years were scored as per Alvarado and RIPASA scoring system. Histopathological reports of the cases were collected and compared with the scores. ROC curve area analysis was performed to examine diagnostic accuracy of RIPASA and ALVARADO scores.Results: The sensitivity of ALVARADO score is estimated to be 52.08 for a cut off of 6. The specificity is 80%, positive predictive value is 92.59, negative predictive value is 25.81. The Diagnostic accuracy of ALVARADO scoring is found to be 56.9. The sensitivity, specificity, positive predictive value and negative predictive values of RIPASA scoring system are 75%, 65%, 91.14%, 35.14%. The diagnostic accuracy of RIPASA score is 73.28.Conclusions: The difference in the diagnostic accuracy between ALVARADO and RIPASA scoring system is significant indicating that the RIPASA score is a much better diagnostic tool for the diagnosis of acute appendicitis. When the ROC curve was observed the area under the curve is high for RIPASA scoring system.

Introduction: Various diagnostic criteria have been described for acute appendicitis. For decades the most commonly used one has been Alvarado score. RIPASA scoring system has also been developed for Asian population which has shown highest sensitivity and diagnostic accuracy. This study aimed to compare these two diagnostic criteria in Nepalese population attending a tertiary center. Methods: Patients with clinically suspected acute appendicitis were classified according to both Alvarado and RIPASA scoring systems before undergoing surgery. Histopathological examination was taken as the gold standard for diagnosis. Statistical analysis was done using McNemar's test as applicable. Results: Ninety nine (90 %) patients had histologically confirmed appendicitis. With the cut-off value greater than 7.5 for RIPASA score; sensitivity, specificity, positive predictive value, negative predictive value, diagnostic accuracy and negative appendectomy rates were 94.5%, 27.27 %, 92.16 %, 37.5 %, 88.18% and 7.84% respectively. With the cut-off value greater than 7 for Alvarado score, sensitivity, specificity, positive predictive value, negative predictive value, diagnostic accuracy and negative appendectomy rates were 71.72%, 72.73 %, 95.95 %, 22.22%, 71.82 %, and 4.05 % respectively. 94.5% of patients were correctly stratified by RIPASA under higher probability group while only 71.8 % were classified by Alvarado (p value= 0.0001). Conclusion: RIPASA scoring system showed high sensitivity and diagnostic accuracy in comparison to Alvarado scoring system. So, this method can be applied in Nepalese setting for the diagnosis of acute appendicitis.

INTRODUCTION: Acute appendicitis is the most common surgical condition presented to the emergency department. Clinical scoring systems such as the Alvarado and modified Alvarado scoring system were developed with the goal of reducing the negative appendectomy rate to 5%–10%. In the other hand the Raja Isteri Pengiran Anak Saleha Appendicitis (RIPASA) scoring system was established in 2008 specifically for Asian population. The aim of this study was to compare the modified Alvarado with the RIPASA scoring system in the Nepalese population. METHODS: This study included 125 patients who had undergone appendectomies from March of 2017 to January 2018. The sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), diagnostic accuracy, predicted negative appendectomy and receiver operating characteristic (ROC) curve of the modified Alvarado and RIPASA scoring systems were derived using SPSS statistical software. RESULTS: A total of 125 patients were included in this study according to our criteria. The cut-off threshold point of the modified Alvarado score was set at 7.0, which yielded a sensitivity of 68.64% and a specificity of 28.57%. The PPV was 95% and the NPV was 5.12%. The cut-off threshold point of the RIPASA score was set at 7.5, which yielded 88.13% sensitivity and 28.57% specificity. The PPV was 95.41% and the NPV was 12.5%. CONCLUSION: Based on the results of this study, the RIPASA score is a simple scoring system with better sensitivity and specificity similar to the modified Alvarado scoring system. KEYWORDS: Acute appendicitis, Modified Alvarado Score, RIPASA score.
