Primary Outcome Measures

Name	Time	Method
Duration of opioid therapy following surgery. This will be collected by data linkage to medical records while the patients remain in hospital and via telephone follow-up after the patient leaves hospital if relevant i.e. if they continue to take opioids. [The data collection for the primary timepoint will cease at 5 days after the patient has remained opioid free and be measured in total days of opioid requirement. this may range from days to weeks.]

Secondary Outcome Measures

Name	Time	Method
Early postoperative NRS pain intensity score[pain intensity for 48 hrs after surgery];Mean NRS pain intensity during opioid therapy duration[Pain intensity measured daily for the period during which the patient requires opioid therapy. This may range from days to weeks.]
