Frailty in lung transplantation: a systematic review

ABSTRACT

Introduction: Lung transplantation is an effective treatment for certain types of end-stage lung disease. Frailty is a complex clinical syndrome associated with decreased physiological reserve and an increased risk for suboptimal health outcomes.

Area covered: This article reviews the current literature on frailty in lung transplantation, with an emphasis on frailty measures, prevalence and impact of frailty on morbidity and mortality prior to and following lung transplantation. Pubmed, EMBASE, CINAHL and Cochrane systematic review databases were searched to September 2019. The search included the MeSH terms ‘frail elderly’ or ‘frailty’ or ‘sarcopenia’ and ‘lung disease’ or ‘lung transplantation’. Studies were included if: the population were undergoing evaluation for, listed for or received a lung transplant; frailty was prospectively assessed during lung transplant evaluation using systematically defined criteria; used human subjects and; published in English. The prevalence of frailty varied from 0% - 58%. The frailty phenotype and short physical performance battery were the most common measures. Frailty was associated with delisting and death pre-transplantation. Frailty was associated with an increased risk of early mortality post-lung transplantation.

Expert opinion: Frailty is identified often in lung transplant candidates and is associated with adverse pre and post-transplantation outcomes. Further research is necessary to identify potential frailty interventions.

Article highlights

• Frailty is identified among lung transplant candidates with prevalence ranging from 0% - 58%, depending on the population, study setting, individual centre practices and the frailty measure used.

• The most common measures used to assess frailty in lung transplant candidates are the FFP and the SPPB.

• Frailty is associated with disability, delisting and death pre-lung transplantation.

• Frailty is associated with increased risk of early mortality post-lung transplantation.

Further research is necessary to determine frailty specific intervention.
