LUNG ALLOCATION SCORE SYSTEM
UPDATE
Current Lung Allocation System
System was implemented on May 4, 2005
The Lung Allocation Score (LAS) is based on a combination of • Expected survival in next year without a
transplant and • Expected survival during 1st year with a transplant
Details of calculation and allocation can be found in Policy 3.7.6
Components Of Current Lung Allocation System:Diagnosis Groups
Diagnosis group
Diagnoses
A COPD/Emphysema; Alpha-1 Antitrypsin Deficiency; Bronchiectasis; LAM; Sarcoidosis with PA mean < 30; Primary Ciliary Dyskinesia
B PPH; Eisenmenger's; Scleroderma (primarily Pulmonary HTN)
C CF; Hypogammaglobulinemia
D IPF; Sarcoidosis with PA mean > 30; Lung retransplant; Obliterative Bronchiolitis (OB); Pulmonary Fibrosis (not IPF); Eosinophilic granuloma; Amyloidosis; Mixed Connective Tissue Disease; Scleroderma (primarily restrictive)

Evaluation of National Kidney Allocation Policy
after the Elimination of HLA-B Matching Points
Background
On May 7, 2003, the kidney allocation system was modified so that:
No points for HLA-B matches
2 points for zero HLA-DR mismatches
1 point for one HLA-DR mismatches.
Previously:
7 points for zero HLA-BDR mismatch
5 points for one HLA-BDR mismatch
Data/Methods
Deceased donor kidney alone transplants performed at 35 DSA’s (with standard HLA points) between 5/7/02 and 5/6/04 were included.
Pediatric recipients and recipients of expanded criteria donor (ECD) kidneys were excluded from the analysis.
Data/Methods
Compare percentage of transplants by ethnicity, HLA MM level, PRA, wait time, and graft survival in two periods:
Pre-policy period: 5/7/02-5/6/03N = 3,236
Post-policy period: 5/7/03-5/6/04N = 3,001

Summary
Compared with pre-policy period:
More minority candidates received a non-zero MM kidney transplant.
More transplants with worse HLA DR MM. More transplants with PRA > 80%. More transplants with longer waiting times. Graft survival rates were similar.

Organs Transplanted Locally vs. Non-Locally
What percentage of organs are transplanted outside the DSA?• Some are offered and refused locally, but are
ultimately transplanted outside the DSA
• Others are offered outside the DSA first (no local patients, Status 1 liver shares, 0MM kidneys, Statewide shares, etc.)
How well do these organs function?• UNetsm Utility for Recovering OPOs
• Overall survival rates shown here (adult donors, excluding repeat txs and multiorgan txs)
