Long-term lung function trajectories in Swedish COVID-19 ICU survivors: a two-year follow-up study.

ABSTRACT:

Introduction

Longitudinal studies of lung function following COVID-19 remain limited. This study examined lung function in COVID-19 patients for two years after discharge from an intensive care unit (ICU).

Methods

Patients treated for COVID-19 in Uppsala ICU (mean 11.1 days) were assessed at four months, one year, and two years post-discharge. Lung function tests included spirometry, diffusing capacity for carbon monoxide (D_Lco), and body plethysmography. Logistic regression adjusted for age, sex, and body mass index (BMI) assessed the association between impaired D_Lco and patients' characteristics.

Result

A total of 104 patients (32% female, with a mean age of 60 years) participated in four months follow-up, 40 in one year follow-up, and 21 in t
