Brief Summary
-----------------
Shared decision-making helps patients to establish a treatment plan with clinicians together. Our goal was to determine if the tools we developed could reduced decisional conflict for patients with obstructive sleep apnea.

Detailed Description

Shared decision-making helps patients to establish a treatment plan with clinicians together. Our goal was to determine if the tools we developed could reduced decisional conflict for patients with obstructive sleep apnea. Inclusion criteria: include obstructive sleep apnea patient from the outpatient clinic of Dean Wu, the sleep center of Shuang-He Hospital, 20-80 years old, polysomnography showed moderate severity (AHI ≥ 15), can communicate in Chinese. Exclusion criteria: dementia, mental illness, language difficulties.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Decision conflict | We'd like to measure the score of SURE test, which published by Légaré at 2008, as a decisional conflict scale. SURE includes 4 questions representing sure of myself, understand information, risk-benefit ratio, encouragement. Each question consisted of a typical five-level Likert item (strongly disagree, disagree, neither agree nor disagree, agree, strongly agree). | Immediately after patient received standard oral explanation with booklet or decision aids at out-patient department | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Health literacy | Self-evaluation score of health literacy. We measure health literacy via one question of SURE test (Sure of myself - Do you feel SURE about the best choice for you?). This question also consisted of a typical five-level Likert item (strongly disagree, disagree, neither agree nor disagree, agree, strongly agree). | Immediately after patient received standard oral explanation with booklet or decision aids at out-patient department |
