Cambridge-Miami score for intestinal transplantation preoperative risk assessment: initial development and validation

Area of Science:

• Transplantation Medicine
• Surgical Outcomes Research
• Biostatistics

Background:

• Accurate preoperative survival prediction is crucial for patient assessment in intestinal transplantation.
• The Cambridge-Miami (CaMi) score has been developed as a preliminary tool for this purpose.
• The score is applicable to isolated or composite small intestine grafts.

Purpose of the Study:

• To develop and validate a preoperative scoring system (CaMi score) for predicting survival after intestinal transplantation.
• To assess the correlation between the CaMi score and patient survival outcomes.

Main Methods:

• The CaMi score incorporates risk factors for early, medium, and long-term survival, including loss of venous access and organ impairment.
• Each factor is scored from 0-3, with higher scores indicating greater risk.
• The preoperative scores of 20 intestinal transplant recipients were compared with their 10-year postoperative survival data.

Main Results:

• A significant inverse correlation was found between the CaMi score and postoperative survival (r(s) = -0.82; P = .0001).
• Patients with a CaMi score <3 had survival rates of ≥3 years (12/12), while those with scores >3 survived <6 months (4/4).
• Kaplan-Meier survival curves showed significant differences between groups, with high accuracy in predicting death (AUC at 3 years = 0.98).

Conclusions:

• The preoperative Cambridge-Miami (CaMi) score demonstrates potential as a reliable predictor of postoperative survival in intestinal transplant recipients.
• Further validation is suggested to establish its clinical utility in patient management.
