Categories of candidate factors considered in predictive modelling of 23-h hospital length of stay in patients undergoing video-assisted thoracosopic lobectomy
| Category | Candidate predictors |
|---|---|
| Patient characteristics | Age, sex, distance from hospital, no. of comorbidities, COPD, smoking status, smoking pack-years, DLCO, FEV1, ASA classification |
| Tumour characteristics | Pathologic stage, clinical stage, indication for resection |
| Surgical factors | Surgeon, era of surgery, surgical complications, chest tube duration, operative time* longer than 120 min, total duration of surgery† longer than 180 min, time of surgery (am v. pm), PACU duration longer than 150 min, lobe removed, additional resection |
ASA = American Society of Anesthesiologists; COPD = chronic obstructive pulmonary disease; DLCO = diffusing capacity of the lungs for carbon monoxide; FEV1 = forced expiratory volume in 1 s; PACU = postanesthesia care unit.
*
Time from first incision to final closure.
†
Total time in the operating room.
