Rana et al developed a preallocation score for Predicting Survival Outcomes Following Liver Transplantation (P-SOFT). This can help to determine which patients are likely to survive following surgery. The authors are from Columbia University College of Physicians and Surgeons in New York City.
Patient selection: candidate for liver transplant
Outcome: post-transplant survival
Parameters:
(1) age in years
(2) body mass index (BMI)
(3) number of previous liver transplants
(4) history of abdominal surgery
(5) serum albumin in g/dL
(6) dialysis prior to transplantation
(7) pretransplant status
(8) MELD score
(9) life support pretransplant
(10) encephalopathy
(11) portal vein thrombosis
(12) ascites pretransplantation

= SUM(points for all 12 parameters)
Interpretation:
• minimum score: 0
• maximum score: 56
• The higher the score the greater the risk.
