Table 1.
Characteristics of patients who the surgeons operated on during the study period
| Total = 722 | |
|---|---|
| Age of patient in years, mean (SD) | 58.1 (16.7) |
| Female patient, N (%) | 379 (52.5) |
| ASA physical status classification system, mean (SD) | 2.1 (0.8) |
| Number of comorbiditiesa, mean (SD) | 2.5 (2.1) |
| Risk score (missing = 6)b, mean (SD) | 0.2 (0.2) |
The following comorbidities were considered: critical condition, current pregnancy, obesity, malnourishment, tobacco addiction, alcohol addiction, other addiction, open wound, surgical site infection, sepsis, endocarditis, cancer, neoadjuvant treatment, immune deficiency, coagulopathy, anticoagulant treatment, anti-aggregation treatment, blood transfusion, coma, limb paralysis, other neurological disorder, confusion, dementia, depression, cardiovascular disease, neurovascular disease, peripheral arterial disease, cardiac arrhythmia, chronic heart failure, hypertension, diabetes, dyslipidemia, high pulmonary artery systolic pressure, chronic renal failure, acute renal failure, chronic respiratory failure, chronic obstructive pulmonary disease, liver disease, rheumatic pathology, and hypoparathyroidism.
In order to take into account the surgical risk of each procedure, a risk score based on all the variables presented in this table as well as the comorbidities listed above was constructed.
