Patient-Reported Quality of Life in Lung Transplantation: Prospective Cohort Study

Area of Science:

• Medical Sciences
• Transplantation Medicine
• Quality of Life Research

Background:

• Lung transplantation (LTx) is a vital treatment for end-stage lung diseases, enhancing survival.
• Post-transplant recovery presents significant physical, psychological, and functional challenges impacting Quality of Life (QoL).
• Limited data exist on early longitudinal QoL changes post-LTx, especially in Chinese populations using disease-specific instruments.

Purpose of the Study:

• To assess QoL and track its longitudinal changes in lung transplant recipients.
• To utilize a disease-specific patient-reported outcome instrument for comprehensive QoL evaluation.
• To identify specific domains of QoL that show significant changes in the early post-transplant period.

Main Methods:

• A single-center prospective cohort study involving 51 lung transplant recipients.
• QoL was measured using the Chinese version of the Lung Transplant Quality of Life questionnaire at baseline and 1-6 months post-surgery.
• Longitudinal changes were analyzed using random-intercept linear mixed models (LMMs).

Main Results:

• Significant time effects were observed in 6 out of 7 QoL domains.
• Health perceptions, respiratory symptoms, and emotional well-being showed the earliest and most substantial improvements.
• Global well-being demonstrated a consistent positive trajectory, with improvements noted as early as 1 month post-LTx.

Conclusions:

• LTx leads to significant QoL improvements in patients with end-stage lung diseases.
• Health perceptions and respiratory symptoms are key areas of QoL enhancement post-LTx.
• Routine monitoring of patient-reported outcomes is crucial for optimizing post-transplant care and recovery.
