Mean cost (in AU$) of imaging and pathology tests performed per patient, with additional cost by complication status in AU$
| No complications N = 405 |
Minor only N = 73 |
Major, at least one N = 22 |
|
|---|---|---|---|
| Imaging | |||
| Mean cost (SD) | 88.9 (101.8) | 201.7 (251.3) | 337.4 (299.4) |
| Additional costa, unadjusted (95% CI) | Reference | + 112.8 (76.3–149.4) | + 248.5 (185.7–311.4) |
| Additional cost, adjustedb (95% CI) | Reference | + 103.7 (66.2–141.1) | + 231.4 (167.4–295.5) |
| Pathology | |||
| Mean cost (SD) | 97.7 (83.6) | 250.3 (285.5) | 329.0 (323.8) |
| Additional costa, unadjusted (95% CI) | Reference | + 152.7 (115.7–189.6) | + 231.3 (167.6–295.0) |
| Additional cost, adjustedb 95% CI) | Reference | + 136.3 (98.0–174.5) | + 217.2 (151.8–282.6) |
a Additional cost represents the cost that is added when the specified type of complication is present, compared to when it is absent
b Adjusted for age, sex, procedure, ASA score, operation time (minutes), anxiety and depression, cancer (past and current), diabetes mellitus, dementia, hypertension, hyperlipidaemia, hyperthyroidism, osteoporosis, urinary incontinence, chronic urinary tract infection, and autoimmune, cardiac, chronic respiratory, cerebrovascular, central nervous system, liver, renal, gastro-oesophageal reflux disease, and past venous thromboembolism
