Multicenter Study Observational Study
Associations between non-anaemic iron deficiency and outcomes following elective surgery for colorectal cancer: a prospective cohort study.
Iron deficiency is present in up to 75% of patients presenting for colorectal cancer surgery. It is unclear whether iron deficiency without anaemia is associated with worse postoperative outcomes. We hypothesised that, in adults without anaemia undergoing surgery for colorectal cancer, iron deficiency would be associated with worse postoperative outcomes relative to an iron-replete state. ⋯ In adult patients without anaemia undergoing surgery for colorectal cancer, iron deficiency defined by transferrin saturation < 20% was not associated with worse patient outcomes and appeared to be associated with more days alive and at home on postoperative day 90.

Multicenter Study Observational Study
Patient-reported outcomes, postoperative pain and pain relief after day case surgery (POPPY): methodology for a prospective, multicentre observational study.
In the UK, approximately 70% of surgical procedures are undertaken as day-cases. Little information exists about recovery from day-case surgery, yet international data highlights patients are at risk of developing significant longer-term health problems including chronic post-surgical pain and persistent postoperative opioid use. The Patient-reported Outcomes, Postoperative Pain and pain relief after daY case surgery (POPPY) study was a national prospective multicentre observational study, measuring short- and longer-term patient-reported outcomes, postoperative pain and pain relief after day-case surgery. ⋯ This paper outlines the methods for the POPPY study, the largest UK multicentre prospective observational study considering short- and longer-term outcomes following day-case surgery.
