Does pain intensity measured on a scale from 0 to 10, in Chinese and Australian Caucasian patients increase unpredictably and if so do the unpredictable levels vary between the two ethnicities? A comparison using the relationships between pain intensity, and pain related functional interference, pain related beliefs and attitudes, pain management satisfaction and opioid related side effects

Primary Outcome Measures

Name	Time	Method
inearity of acute postoperative pain intensity (with reference to a 10 point Pain Numeric Rating Scale) in relation to pain related interference (a composite of movement , breathing, sleep and mood) in BOTH Caucasian Australian and Chinese populations. Subjects will be asked to quantify how much their pain has interfered with Movement, breathing, sleep and mood on a numeric rating scale where zero indicates no interference and 10 the greatest possible interference. [Relevant measurements for postoperative pain intensity in relation to pain related interference will take place once prior to surgery and once 24 hours following surgery. ]
