The use of multiple instruments can pose some interesting research questions, such as whether the outcomes produced by the different instruments are in agreement. We tackle this problem using information theory, focusing on mutual(More)
Continuous positive airway pressure therapy (CPAP) is known to be the most efficacious treatment for obstructive sleep apnoea (OSA). Unfortunately, poor adherence behaviour in using CPAP reduces its effectiveness and thereby also limits beneficial outcomes. In this paper, we model the dynamics and patterns of patient adherence behaviour as a basis for(More)

Considering frequent demand changes regarding resource priorities, appointment alterations, and time windows in HCCSP, the control(More)
The clinical guidelines for the evaluation, management, and longterm care of obstructive sleep apnea (OSA) in adults emphasize a multidisciplinary, chronic care approach to the treatment and management of OSA [1]. The guidelines, consistent with earlier practice parameters [2], include consensus standards to monitor early continuous positive airway pressure(More)
