Post Surgical Pain
The incidence of chronic post-surgical pain (CPSP) is at an increase, with increase in the number of surgeries being performed. The first publication that identified surgery as a risk factor for chronic pain appeared in 1998. This finding led to a dramatic increase in interest on this subject.
There is no universally agreed definition of chronic post-surgical pain; however, the working definition proposed by Macrae and Davies is commonly used. Chronic post-surgical pain is associated with increased analgesic use, restriction of activities of daily living, significant effects on quality of life and increased health-care utilization. More than 4 million people undergo surgery every year in the UK, so chronic post-surgical pain poses a significant economic and health-care burden.
