Four months after their release from the hospital, more than half of 238 adult COVID-19 patients in northern Italy still had impaired lung function or mobility issues, and about one-fifth had symptoms of posttraumatic stress disorder (PTSD), a prospective cohort study published yesterday in JAMA Network Open found. The findings add to growing evidence and discussion of so-called COVID-19 “long-haulers,” or patients with function-impairing symptoms persisting for months after their initial recovery. Researchers from two universities in Novara, Italy, assessed the patients, who had been hospitalized from Mar 1 to Jun 29, 2020. Of the 219 patients who completed both lung function tests and carbon monoxide (CO) measurements, 113 (51.6%) had a diffusing lung capacity for CO of less than 80% of the expected level, indicating compromised lung function, and 34 patients (15.5%) had more severe impairment, with a value less than 60% of normal.
