Postoperative Hb decline is independently associated with prolonged LOS after elective upper GI cancer surgery.
Study context
- Population
- Patients undergoing elective upper gastrointestinal (GI) cancer surgery at a tertiary hospital in Western Australia
- Participants
- 111 patients
- Exposure

- Prolonged LOSn = 26
- Outcome
- Prolonged LOS (above procedure-specific median LOS); association with Hb
Methodological detailssingle-centre, multivariable logistic regression
- Single-centre
