Encuesta de síntomas SNOT-20 para rinitis alérgica y rinosinusitis: validación en Chile

Abstract

Validation of the sino-nasal outcome test in Chile Background: Allergic rhinitis and sinusitis are common diseases that affect quality of life of pediatric and adult patients. Aim: To adapt and validate the Sino-Nasal Outcome Test 20 indicators (SNOT-20) survey in Chilean subjects. Material and Methods: In a psychometric validation study, an adapted version of the SNOT-20 adapted version was applied to 181 volunteers on two different occasions, three weeks apart. Feasibility (response time and perceived diffi culty), reliability (internal consistency and test-retest) and validity (concurrent validity, correlating results with an independent instrument; predictive validity assessing its sensitivity to detect changes and discriminant validity, assessing receiver operating characteristic (ROC) curves), were assessed. An exploratory factor analysis was performed to confi rm the presence of previously described underlying constructs. Results: Eighty percent of participants considered SNOT-20 easy to complete. This task was completed in less than 5 minutes. Cronbach's alpha was 0.946. Temporal stability on a healthy subgroup was strong with an intraclass correlation coeffi cient of 0.92. SNOT-20 had a correlation coefficient of 0.82 with an independent instrument and its score signifi cantly decreased after 3 weeks of treatment (p = 0.003).The area under ROC curve was 0.895. Factor analysis identifi ed four principal components which possessed identical structure as previously described. Conclusions: SNOT-20 survey was valid, reliable and easy to implement among Chilean subjects.

“…La eficacia del tratamiento se determinó a través de la puntuación global del cuestionario SNOT-20 (Sino-Nasal Outcome Test), 16 además se evaluó la información reco-lectada mediante la historia clínica, la exploración física con rinoscopia anterior, la puntuación del cuestionario T5SS (Total 5-Symptom Score), 17 y el cuestionario sobre la satisfacción con el medicamento (TSQM, Treatment Satisfaction Questionnaire for Medication). 18 Las evaluaciones se llevaron a cabo durante la valoración basal (día -7), al inicio del tratamiento (día 1), al día 21 (seguimiento) y al final del tratamiento (día 42).…”

Cross-sectional survey about the prevalence of allergic rhinitis in Argentina: Study PARA

“…La rinitis alérgica (RA) es la enfermedad respiratoria crónica más frecuente en todo el mundo, 1,2,3 con frecuencia está asociada con otras comorbilidades como sinusitis, otitis media y, especialmente, asma, y provoca un deterioro signifi cativo en la calidad de vida, con peores indicadores que enfermedades como la diabetes mellitus, la artritis reumatoidea o la migraña. 4 Los datos epidemiológicos sugieren que la prevalencia de rinitis alérgica está aumentando en todo el mundo . 5 De hecho, varios informes indican una tendencia creciente en la prevalencia de esta enfermedad, especialmente en los países en desarrollo, posiblemente relacionada con la contaminación ambiental, los cambios climáticos, el crecimiento urbano y la adopción de estilos de vida similares a los de los países desarrollados.…”
