  • Gold standard for diagnosis is attended PSG
  • Timely access to diagnosis and treatment is restricted in many countries (Flemons et al., AJRCCM, 2004)
  • Excessive waits lead to new technologies
  • Few current recommendations support the use of portable monitors (Chesson et al, AJRCCM, 2004)

Questionnaire

Some sample questions:

  • Do you perform comprehensive PSG studies, and if so: how many and using what equipment?
  • Do you use portable monitors, and if so: are they used on-site or off-site?
  • How many portable studies do you perform, using what system, what channels, and why do you use this system?
