All Retrospective Studies Using SAS Scores for Various Surgeries to Predict Immediate and Delayed Postoperative Complications (30 days).
| Surgery Type (# of Patients) Ref. | Prognostic Value (Y/N) | Remarks |
|---|---|---|
| Knee arthroplasty (3,511)13 | No | The authors felt SAS was insufficient for prognostication |
| Colectomy (795)14 | Yes | SAS predicted inpatient as well as late post-discharge complications |
| General/vascular surgery (4,119)15 | Yes | |
| Major intra-abdominal surgeries (8,501)16 | Yes | |
| Esophagectomy (189)17 | Yes | SAS predicted major morbidity associated with longer hospital stay |
| Esophagectomy (168)18 | Yes | |
| Ivor Lewis (234)19 | No | SAS could not predict adverse outcomes |
| Esophagectomy (399)20 | Yes | |
| Gastrectomy (328)21 | No | Original SAS not found useful; modified SAS was helpful in predicting complications |
| Hysterectomy for malignancy (632)22 | No | SAS uncorrelated with postoperative events |
| Pancreatoduodenectomy (2012)23 | Yes | |
| Intracranial and spine neurosurgery (918)24 | Yes | |
| Surgery for spinal metastasis (97)25 | No | SAS an insignificant predictor of major perioperative complications following spinal metastasis surgery; preoperative functional status and age were stronger predictors |
| Lower extremity amputations (228)26 | Yes | Predicted potential development of complications |
| Wide surgical subspecialties (123,864)27 | Yes | |
| Intracranial meningioma excision (999)28 | Yes | SAS predicted early and late complications |
| Pancreatoduodenectomy (103)29 | Yes | SAS was a significant independent risk factor for overall and recurrence-free survival |
| Radical prostatectomy (994)30 | Yes | |
| Lumbar spine fusion (199)31 | Yes | |
| Gastrectomy (191)32 | Yes | SAS predicted survival after surgery |
| Major intra-abdominal surgery (629)33 | Yes | SAS predicted survival after surgery |
| Kidney transplant (204)34 | Yes | SAS correlated with ICU stay and overall cost of treatment |
| Microvascular head and neck reconstruction (154)35 | No | SAS uncorrelated with postoperative complications |
| Surgery for traumatic hip fractures (43)36 | Yes | |
| Pancreatic resection (143)37 | Yes | SAS along with hypoalbuminemia and blood transfusion correlated well with hospital stay and complications |
| Major gastrointestinal surgeries (1,833)38 | Yes | The authors modified SAS by including intraoperative blood transfusion and assigned zero estimated blood loss (EBL) score to patients who received transfusion; they concluded that intraoperative transfusion improved risk stratification of SAS |
