STOP-Bang as a predictor of obstructive sleep apnea-hypopnea syndrome in outpatients. Duazary. 2021 octubre; 18(4): 344- 349. Doi: https://doi.org/10.21676/2389783X.4371 Received on November 12 of 2020 Accepted on September 16 of 2021 Published online November 15 of 2021 ABSTRACT The STOP-Bang has been promoted as a valuable tool for identifying obstructive sleep apnea-hypopnea syndrome (OSAHS) in medical and surgical patients. However, its performance in Colombian samples is unknown. The objective of this study was to determine the clinimetric performance of the STOP-Bang index versus the study of polysomnography in patients from Santa Marta, Colombia. An accuracy study of diagnostic tests with a test-based approach was designed. Seven hundred sixty-two adults referred for polysomnography to evaluate OSAHS were included in the research. They were aged between 18 and 94 years old (mean=47.2, SD=13.4), 63.3% were men, and 46.5% were classified as obese. The STOP- Bang performance was compared against the best reference criterion, the hypopnea/apnea index determined by polysomnography. The diagnosis of OSAHS was confirmed in 461 (60.5%) and corroborated in 301 (39.5%). The area under the curve was 0.70 (95%CI 0.66-0.74), and the best cut-off point was 4, with a sensitivity of 79.2%, a specificity of 53.5%, the positive predictive value of 72.2%, the negative predictive value of 62.6%, positive likelihood ratio was 1.70, negative likelihood ratio was 0.39; OR=4.08 (CI95% 2.99-5.56) and Cohen's kappa of 0.33. As conclusions, performance indicators show that STOP-Bang has little utility as a predictor of OSAHS in the evaluated population. This indicator should be abandoned. RESUMEN El STOP-Bang ha sido promocionado como una herramienta útil para identificar casos de síndrome de apnea/hipoapnea obstructiva del sueño (SAHOS) en pacientes médicos y quirúrgicos. Sin embargo, no se conoce su desempeño en muestras colombianas. El objetivo de este estudio fue determinar el desempeño clinimétrico del índice STOP-Bang frente a polisomnografía en pacientes de Santa Marta, Colombia. Se diseñó un estudio de precisión de una prueba de diagnóstico. Se contó con la participación de 762 adultos que fueron remitidos para polisomnografía. Se solicitó la participación de adultos (entre 18 y 94 años; media=47,2; DE=13,4); 63,3% hombres y 46,5% obesos. El rendimiento del STOP-Bang se comparó frente el mejor criterio de referencia, el índice de hipopnea/apnea determinado por polisomnografía. El diagnóstico de SAHOS se confirmó en 461 (60,5%) y se corroboró en 301 (39,5%). El área bajo la curva fue 0,70 (IC95% 0,66-0,74) y el mejor punto de corte fue 4, con sensibilidad de 79,2%, especificidad de 53,5%, valor predictivo positivo de 72,2%, valor predictivo negativo de 62,6%, razón de probabilidad positiva de 1,70, razón de probabilidad negativa de 0,39; OR=4,08 (IC95% 2,99-5,56) y Keywords: Obstructive Sleep Apnea; Polysomnograp hy; Outpatients; STOP-Bang index; Validation Studies.
