Evaluating mortality risk in elderly lung transplant patients

Area of Science:

• Cardiology
• Transplant Surgery
• Gerontology

Background:

• Lung transplantation survival rates have improved significantly.
• Limited data exists on mortality risks for elderly lung transplant recipients.
• This study addresses the need for data on this specific demographic.

Purpose of the Study:

• To assess mortality risks in elderly lung transplant recipients.
• To compare outcomes between elderly and younger lung transplant recipients.
• To identify predictors of post-transplant survival in this population.

Main Methods:

• A cohort study was conducted using a single-institution lung transplant registry (January 2018 - December 2023).
• Baseline characteristics and post-transplant complications (infections, rejection) were analyzed.
• Survival rates and predictors of mortality were evaluated.

Main Results:

• Elderly recipients (16.0%) were less likely to receive bilateral transplants and had lower Lung Allocation Scores.
• One-year survival rates did not significantly differ between elderly (82.7%) and younger (90.1%) cohorts.
• Serum creatinine level > 0.85 mg/dL was the sole significant predictor of post-transplant survival (OR: 10.9).

Conclusions:

• Lung transplantation outcomes are favorable in elderly recipients.
• Current age-based eligibility standards for lung transplantation warrant re-evaluation.
• Serum creatinine is a critical factor for predicting survival post-lung transplant.
