Toolbox

The UMass Surgical Outcomes Analysis & Research group has developed a number of tools to help predict outcomes after operations, including in-hospital mortality and complications. These "risk scores" stratify patients in various settings according to their specific characteristics and circumstances. Please note that these resources are intended as research tools; they describe national averages only, and the estimates they provide must be interpreted in context by an experienced clinician. The following tools are available:

• A Simple Risk Score for Pancreatectomy 
  The score is designed to augment, not replace clinician judgment and informed consent, and must be interpreted in the context of the individual patient and surgeon.

• Perioperative Mortality for Management of Hepatic Neoplasm: A Simple Risk Score 
  This tool preoperatively stratifies patients undergoing a surgical procedure for hepatic neoplasm (either primary or metastasis) according to their individual risk of in-hospital mortality.
   
• In-hospital Mortality after Liver Resection for Hepatocellular Carcinoma: A Simple Risk Score
  This tool preoperatively stratifies patients undergoing a surgical procedure for hepatocellular carcinoma according to their individual risk of in-hospital mortality.
   
• In-hospital Mortality for Liver Resection for Metastases: A Simple Risk Score 
  This tool preoperatively stratifies patients undergoing a surgical procedure for metastatic disease to the liver according to their individual risk of in-hospital mortality.
   
• Predicting Major Postoperative In-Hospital Complications after Laparoscopic Cholecystectomy: A Simple Risk Score
  This tool assists in preoperatively predicting individual patient risk of developing a major postoperative complication following laparoscopic cholecystectomy.
