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
