Timing of lung transplant evaluation: considerations, barriers and alternatives.

PURPOSE OF REVIEW: Over the past decade, increased knowledge has contributed to improved medical and technical treatments across the spectrum of respiratory diseases. As a result, timing for transplant evaluation might be more challenging. In this review, the focus is on timing of lung transplant evaluation of patients from the main respiratory diseases referred. Disease-specific predictors of survival in relation to timing of transplant evaluation and alternative treatments will be reviewed.

RECENT FINDINGS: Treatment options have evolved for respiratory diseases like chronic obstructive pulmonary disease, pulmonary fibrosis, cystic fibrosis and pulmonary arterial hypertension. These treatments have led to improved quality of life, exercise tolerance, lung function and outcome. However, the effect of these alternative treatments on transplant candidacy and knowledge on timing of lung transplant evaluation are lacking.

SUMMARY: This article reviews the current best evidence to guide clinicians regarding the optimum timing for transplant referral and highlights considerations to optimize transplant candidacy and outcomes.
