Abstract
No regulatory mandate exists in the United States (U.S.) for comprehensive obstructive sleep apnea (OSA) risk assessment and stratification for commercial motor vehicle (CMV) drivers. Current Federal Motor Carrier Safety Administration (FMCSA) requirements are outdated and depend largely on subjective report, a less reliable strategy in an occupational setting. Without FMCSA standards, sleep specialists, occupational medical examiners and employers rely on a collection of medical consensus recommendations to establish standards of care. These recommendations advise OSA risk assessment through a combination of focused medical history, physical examination, questionnaires, and accident history, which increase OSA detection compared to current FMCSA standards. For those diagnosed with OSA, consensus-based risk stratification helps identify CMV drivers who may benefit from OSA treatment and establish minimum standards for assessing treatment efficacy and adherence. Unfortunately no consolidated recommendation exists; rather, publications span medical and governmental literature in a patchwork fashion that no longer fully reflect current practice due to subsequent advances in OSA diagnosis, treatment, and technology. Based on searches of medical literature, internet materials, and reference lists from existing publications, an overview and discussion of key published recommendations regarding OSA assessment and treatment in CMV operators is provided. Suggestions for incorporating these recommendations into clinical sleep medicine practice in the U.S. are presented. The challenge for sleep specialists is maintaining the delicate balance between recommendations impacting standard of care and associated medico-legal impact with stakeholder interests from medical, regulatory, industry and public perspectives while providing high quality and efficient care.
