Patient‐reported outcomes, postoperative pain and pain relief after day‐case surgery ( POPPY ): chronic post‐surgical pain prevalence and associations*

Day-case surgical activity is increasing in the UK yet there is a lack of data on the prevalence of chronic post-surgical pain in this population. This study uses data from the POPPY study to estimate the prevalence of chronic post-surgical pain after day-case surgery, its relationship with quality of life and also explores associated factors.

Data were collected from eligible consenting adults having day-case surgery in 199 sites across the UK. Baseline data were collected on the day of surgery, and patients were followed up by short message service-delivered questionnaires on day 1, day 3, day 7 and day 97. Chronic post-surgical pain was defined using pain severity scores at day 97. Multivariable logistic regression models were used to explore associations with chronic post-surgical pain.
