Lung Allocation Scores Revised

Posted by:

The Lung Allocation Score (LAS) calculations implemented in 2005, avoided transplants in those who were considered to have poor survival rate, and applied to adolescents (aged 17-17 years) and adults (aged 18 years and older).

Since June 10, 2013, pediatrics under 12 years and listed for lung transplant can ask for an exception from the national Lung Review Board and be assinged a LAS in order to be listed for lung offers from adult and adolescent donors.

The U.S. Department of Health & Human Services Organ Procurement and Transplantation Network (OPTN) released modified guidelines to their LAS system, which became effective February 19, 2015.

A report, published by the American Journal of Transplantation, on the OPTN/SRTR 2013 Annual Data Report, was coauthored by Dr. Maryam Valapour of the Cleveland Clinic Department of Pulmonary Medicine, Respiratory Institute at Cleveland, Ohio. Dr. Valapour was instrumental in the analysis of the new LAS guidelines.

The conclusion of the report continues to prefer bilateral lung transplant, which represented 70% of lung transplant events in 2013, and that both long- and short-term survival rates have plateaued since the LAS was implemented in 2005. The biggest change to the revised guidelines are for patients with pulmonary hypertension who will be granted higher priority.
