Validación de la escala de respuesta inflamatoria (air) en apendicitis aguda, en pacientes de 16 a 35 años. Hospital Vicente Corral Moscoso, Cuenca 2020

Abstract

Acute appendicitis is the most frequent surgical pathology in our environment; its annual mortality rate is 2.4 / 1000 appendectomies. The diagnosis is mainly clinical, however, risk stratification based on scores can optimize the management of these patients. Objective: Determine the validity of the inflammatory response scale in acute appendicitis (AIR) in patients aged 16 to 35 years. Vicente Corral Moscoso Hospital. Cuenca 2020. Methodology: This is a diagnostic test validation study; The sample considered consisted of 177 medical records of patients who met the inclusion criteria, selected by simple random sampling. For data collection, a questionnaire validated by the author was created. The SPSS v 24 program was used to obtain the measures of central tendency and dispersion, Sensitivity (S), Specificity (E), Positive and negative predictive value (PPV and NPV), ROC curve. Results: the average age of the participants was 25.11 (SD ± 5.3), and the most representative group was young adults from 25 to 34 years old; in relation to sex, there was no significant difference. 10.88% of the patients who had an AIR score ≥ 8 were positive for acute appendicitis on histopathological analysis. The S of AIR ≥ 8 was 10%, the E = 100%, the PPV = 100%; NPV = 18.63%. The AIR test efficiency ≥ 8 was = 25.99%. The probability of having a negative result (ARI <8) was 89% (negative likelihood index). Conclusion: the validity of the AIR test ≥ 8 to determine the probability that an individual has acute appendicitis was low, therefore, this value is insufficient, therefore, the help of complementary tests is suggested.
