  2. Background • Prevalence of OSAS for men & women is 4% and 2% respectively (Young et al., NEJM, 1993) • 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)

  3. AIMS • To assess the prevalence of portable device use in Australia and NZ in 2005 • To assess the reason for the of use of portable monitors • To generate discussion on the role of portable monitoring in sleep medicine today and in the future

  4. Method • Developed a questionnaire • Mailed survey to all known sleep services in Australia & NZ in July 2005 (N = 118) • Reminder email sent to ASTA members in August 2005 • Second mail out to non-responsive Sleep Services in September 2005

  5. 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?
