Experts at Cleveland Clinic are hoping to rework the scoring equation that ranks patients awaiting lung transplants and improve overall outcomes.The equation — known as the Composite Allocation Score — ranks transplant candidates based on stability while awaiting the transplant and also chances of survival.

克利夫兰诊所的专家希望重新制定评分方程，对等待肺移植的患者进行评分并改善总体结果。该方程-称为复合分配评分-在等待移植时基于稳定性和存活机会对移植候选者进行排序。

However, the tests used to determine the score are only given to patients twice a year, meaning they go six months without re-evaluation. During that time, their health could change drastically, which prompted Cleveland Clinic experts to seek a solution that evaluates their transplant needs more efficiently. And while the number of patients on the lung transplant waitlist have gone down slightly in recent years, there is still a shortage of available organs in the U.S., according to a Sept.

然而，用于确定分数的测试仅每年两次给予患者，这意味着他们需要六个月而无需重新评估。在此期间，他们的健康状况可能会发生巨大变化，这促使克利夫兰诊所专家寻求更有效地评估其移植需求的解决方案。根据9月的数据，虽然近年来肺移植等候名单上的患者人数略有下降，但美国仍然缺乏可用的器官。

Connecting the patients who are most in need of a transplant with a match quickly improves survival outcomes, they said.'The problem with this method is that the scoring equations fail to consider how a patient's health status changes as they spend more time on the list,' Maryam Valapour, MD, a lead author of the study and director of lung transplant outcomes at Cleveland Clinic stated in the news release.

'The longer a patient lives with a severe lung disease, the more their risk of developing severe complications increases. This is something clinicians observe every day – that our patients' risk of developing complications changes over time. Therefore, some patients' scores may not reflect how urgently they need a transplant.'For the study — which was published Sept.
