Resumen Objetivo Valorar la interpretacion de ApnealinkTM® (AL) por medicos de atencion primaria (MAP), y la alcanzada mediante poligrafia respiratoria (PGR) en la Unidad de Sueno Hospitalaria (USH) en pacientes con alta probabilidad de sindrome de apnea e hipopnea del sueno (SAHS). Metodos Se recogen aleatoriamente, durante tres meses, pacientes seleccionados en USH para estudio mediante PGR, con elevada probabilidad de SAHS que aceptaron repetir estudio mediante AL. La USH corregia la PGR segun normativa SEPAR; el MAP corregia el AL y planteaba manejo. Se analizaron los pacientes con estudios validos(tiempo registro ≥ 240 min) para ambos dispositivos, comparandose resultados. Se considero el estudio AL automatico y corregido, considerando un indice de desaturacion de oxihemoglobina (ODI) al 4% (ODI 4%), (AL 4%) y al 3% (ODI 3%), (AL 3%). Cuando ODI 4% era ≥ 12/h, se establecio diagnostico SAHS moderado/grave, suponiendo un IAH ≥ 15/h. Para interpretar AL con ODI 3% y tratamiento, se siguieron criterios SEPAR. Se compararon los resultados para las mismas variables del AL frente a PGR. Resultados Se incluyeron 43 pacientes validos para AL, 45 para PGR y 41 validos para ambos estudios. El estudio AL 4% mostro 27 (62,8%) positivos (OR 5,5, p Se compararon los resultados para las mismas variables del AL frente a PGR. Conclusiones Existe equivalencia entre las decisiones del MAP y la USH. El AL seria un buen metodo diagnostico de SAHS en atencion primaria, en pacientes seleccionados con alta probabilidad de SAHS.

To assess diagnosis and therapeutic decisions-making by General Practitioners (GP) using ApnealinkTM® (AL) in patients with high suspicion of obstructive sleep apnea (OSA), in comparison with conclusions of Hospital Sleep Unit (HSU) specialists based on home respiratory polygraphy (PGR) results.This study involved patients previously selected by HSU for sleep testing by PGR. After it, patients were offered to complete AL test. PGR was checked at HSU; AL was checked by hemoglobin desaturation index of 4% (4% ODI), (4% AL) and 3% (3% ODI) patients with positive test to proceed with CPAP; and those with negative test for further testing. Automatically adjusted 4% AL, was considered valid as it was demonstrated to be equivalent to manual AL. Results were compared by automatically adjusted 3%AL against PGR results.48 patients were collected. 43 had AL valid test, 45 had PGR valid study, and 41 had both valid test. 27 patients (62,8%) had positive 4% AL (OR 5,51, p0,05), that showed AHI ≥ 15/h at 3% AL test; and 19 patients (42,2%) had a positive PGR test. 31 (72%) patients had a positive 3% AL. AL had shown to be a good screening method of SAHS.There is equivalence between the decisions of GP and HSU. AL is a good diagnostic tool and screening method for OSA in primary care when it is used in patients with high suspicion of moderate-severe OSA.
