Development and testing of cost effective approach to screening, diagnosis, and treatment of sleep apnea on commercial motor carriers: Alberta and Texas pilot tests
2005
This presented work involves the development and successful field operational testing of a step-wise, cost effective and practical approach for screening, diagnosis and timely treatment of sleep disorders, as part of a comprehensive fatigue management program which included: sleep disorders screening, diagnosis and treatment, educational modules, operational interventions, pre/post evaluation process. In this sample, 71 percent had at least a mild degree of sleep apnea, with 38 percent of the Alberta drivers warranting intervention and treatment. The sequential approach utilizing ambulatory screening accurately predicted the conditions in 91 percent of tested participants in the pooled Alberta and Texas sample, with no false negatives noted. Of the drivers diagnosed with the condition in Alberta, 78 percent improvement was noted in sleep time, with an increase from mean sleep of 3.9 hours to 6.8 hours on work days. This step-wise, cost effective approach to screening and diagnosing of this condition in an operational environment has been successfully pilot tested with good reception by participating operators, timely access to treatment and intervention when required, and no interference with the individuals work schedule and driving ability.
