The Sleeping Giant

You’ve probably heard the saying ‘Early to bed, early to rise, makes one healthy, wealthy and wise’. While this is somewhat true it’s not just the length of time we spend in bed, but the quality of our sleep. Think about it, don’t you feel so much better after 7 hours of deep uninterrupted sleep than after 9 hours of broken sleep? Sure you do.

Obstructive Sleep Apnea (OSA) is highly prevalent in Australia and is likely to be costing Australian companies millions. OSA is characterized by a narrowing of the airway during sleep that leads to events called Apneas (stopping the flow of air into the lungs) and/or Hypopneas (limiting the flow of air into the lungs). These events are associated with a significant decrease in blood oxygen levels.

 The stats;

·         One in 20 adults are at risk of moderate to severe OSA. (2,3)
·         Over 25% of all adults may need investigation for OSA. (1,2)
·         OSA prevalence is likely to rise even further due to Australia’s high obesity rates and aging population. (1)
·         Approximately 80% of Australians with OSA remain undiagnosed. (7)

But wait there’s more;

•       Untreated OSA sufferers are 7 times more likely to suffer a stroke. (5)
•       A person with sleep apnea is 7 times more likely to have a motor vehicle accident. (6)
•       People with sleep apnea are 3 times more likely to suffer a work-related injury or fatality. (6)
•       The odds for developing depression are increased by two fold in people with OSA. (9)
•       Deloitte Access Economics have estimated that OSA alone cost the Australian economy more than $21     Billion in 2010. (3)

Australian Companies Unaware
Australian companies are aware of the issues and associated costs around poor Nutrition and lack of Physical Activity, and are actively implementing programs to educate and support behaviour change Sleep Apnea however, really is the Sleeping Giant, with most companies oblivious to the risk and associated costs. The majority of companies do not have an effective sleep solution.

Some sectors are taking action – OSA risk management
The National Standard for Health Assessment of Rail Safety Workers contains set criteria for the assessment of sleep disorders, including Sleep Apnea, that do not rely solely on employee self-assessment (because let’s face it employees will not always tell the entire truth), but rather on both demonstrated sleepiness and clinical risk factors. Clinical factors that impact sleep include high BMI, high Blood Pressure requiring medication and Type 2 Diabetes. Great to see rail taking such proactive measures.

Does your organisation have a way of identifying sleep issues and providing effective solutions?
One way to identify how big the sleep issue is within your organisation is to follow rail’s lead and use the next round of general health checks to identify the sleep risk factors (high BMI, BP and Type 2 Diabetes). You’re provider will also need to include a sleep survey like the Epsworth Sleepiness Scale. Using the survey results and clinical risk factors your organisation will be able to identify employees with potential sleep disorders. Employees will need to give their consent for their health data to be shared with their employer if the employer will be funding further investigation and treatment. If the employee will be funding further testing and treatment your provider can refer employees for a sleep study.

Epworth Sleepiness Scale
The Epworth Sleepiness Scale is a questionnaire developed by Dr. Murray Johns of Melbourne to measure daytime sleepiness. With 8 simple questions, you can decipher if you may be suffering from daytime sleepiness a large symptom of many sleep disorders. Download the Epworth Sleepiness Scale here.

At Elevate, respiratory and sleep specialist Dr Kevin Chan leads our sleep disorders clinic. If you suffer from daytime sleepiness or struggle to get a good nights sleep, download our Referral Form to take to your GP.  Once referred, contact Elevate on 9252 2225 to book an appointment with Dr Kevin Chan.
