Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
The primary aim is to develop and evaluate an Obstructive Sleep Apnea (OSA) screening algorithm against the results of polysomnography.The research assistants will approach all patients visiting chronic pain clinics for eligibility. For recruited patients, a written informed consent will be obtained. All recruited patients will undergo polysomnography at the Toronto Rehab Institute Sleep Lab or Toronto Sleep and Pulmonary Centre. An overnight oximetry by an oximeter will be collected. The sleep physician will review the polysomnography results.
All recruited patients will also complete the STOP-Bang questionnaire and Epworth Sleepiness Scale (ESS). The thyromental distance, Mallampati classification, Friedman staging,neck circumference and oxygen saturation will be measured. Demographic data, co-morbidities, medications and an overnight oximetry will be collected.
Patients will be assessed on their opioid-related knowledge via the Patient Opioid Education Measure (POEM) at the first visit. They will be educated on knowledge of opioids via education sheet, pamphlet and video from ISMP-Canada, and then repeat Patient Opioid Education Measure (POEM) 6- 8 months later during pain clinic follow up visit.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Pre-education intervention
All study participants will be tested with a questionnaire (POEM; Patient Opioids Education Measurement) on their opioid knowledge during 1st visit at the pain clinic.
Pre-education intervention
All study participants will be tested with a questionnaire (POEM; Patient Opioids Education Measurement) on their opioid knowledge during 1st visit at the pain clinic.
Post-education intervention
All study participants will be educated on opioids via an education sheet, pamphlet and video from the Institute for Safe Medication Practices (ISMP) Canada. They will repeat the questionnaire (POEM) after this education on opioid knowledge on the same day.
Post-education intervention
All study participants will be educated on opioids via an education sheet, pamphlet and video from the Institute for Safe Medication Practices (ISMP) Canada. The questionnaire (POEM) will be tested again after this education on opioid knowledge on the same day.

Eligibility Criteria
Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.
Inclusion Criteria
Exclusion Criteria
2. Patients requiring urgent sleep physician referral (within four weeks) due to serious medical conditions or safety critical-occupations according to the 2011 Canadian Thoracic Society (CTS) guidelines\[60\] e.g. unstable ischemic heart disease, recent cerebrovascular disease, congestive heart failure, refractory systemic hypertension, pulmonary hypertension, hypercapnic respiratory failure or pregnancy.
3. Conditions potentially interfering with comprehension and delivery of informed consent or the educational intervention, such as neurological or psychiatric disorders.
4. Patients with a prior diagnosis of sleep-related breathing disorder within the last 3 years with treatment. Patients who may have had sleep studies 3 or more years earlier may be included, if they have been lost to follow-up by a sleep physician, are not on treatment or are non-compliant
