Conductas de riesgo en pacientes con síndrome de apneas-hipopneas del sueño: estudio exploratorio en situaciones complejas y dinámicas de tráfico simulado

Abstract

Objective: A large consensus exists within the scientific community with regard to the existence of a high incidence of traffic accidents in people with Sleep Apnea Hypopnea Syndrome (SAHS). However, some aspects of this relationship are still in need of clarification. It has not been possible to show the likely cause of this large rate of accidents, there are possible uncontrolled, confounding factors, and some of the evaluation instruments used have low ecological validity. The goal of the study was to analyze risk behavior during driving in patients with SAS, in a virtual reality setting with simulated traffic.

Material and methods: Evaluation of risk driving behavior was carried out using the Honda Riding Trainer simulator. The participants were 12 patients diagnosed with SAS, treated with continuous positive airway pressure (CPAP), and 12 matched controls. Daytime somnolence, mental fatigue, and levels of activation during the tests, were also evaluated in both groups through the use of questionnaires.

Results: Although patients with SAHS showed higher daytime somnolence, they did not exhibit more risk driving behaviors than the control group. There were no differences in mental fatigue or levels of activation during the simulation.

Conclusion: Unlike the results found in classical studies, when the evaluation is carried out with more ecological tools and the duration of the tests is much shorter, the performance of patients with SAS treated with CPAP does not differ from that of the control group. These findings support the use of CPAP as well as the testing of drivers using virtual simulations in order to obtain a driver's license, especially in high risk populations.
