Abstract

Background: Nontuberculous mycobacterial pulmonary disease (NTM-PD) is a chronic lung infection associated with persistent respiratory symptoms and diminished health-related quality of life (HRQoL). As with other chronic conditions, increased levels of anxiety and depression can impact prognosis and HRQoL. Objectives: To describe the prevalence of anxiety and depression and to identify HRQoL domains that are correlated with mental health in patients with NTM-PD. Design: A cross-sectional observational study of adults with self-reported or clinically confirmed NTM-PD. Methods: Participants with NTM-PD enrolled in two studies ( n  = 40 interview + surveys and n  = 230 completing electronic surveys only) at four U.S. sites. Inclusion criteria were age >18 years, English-speaking, and U.S. residence. In-person enrolled participants met ATS/IDSA criteria and had symptom documentation in medical records; remotely enrolled participants self-reported NTM-PD and symptoms. Data collected included demographics, GAD-7 and PHQ-8 (anxiety and depression screening, respectively), QOL-B Respiratory Symptoms Scale (RSS), selected PROMIS short forms (Fatigue 7a, Cognitive Function 6a, Sleep Disturbance 4a), and Patient Global Impression of Severity of NTM-PD symptoms (PGIS). Interview-only participants completed the GAD-7, PHQ-8, QOL-B RSS, and were evaluated for cognitive functioning using the computerized Symbol Digit Modalities Test (oral version). Results: The study population was predominantly female (57%/91% in the interview/survey studies, respectively) and aged >65 years (50%/77.4%). Overall, 18%/14% screened positive for anxiety and 32%/18% for depression. Participants screening positive for anxiety or depression had significantly lower QOL-B RSS, cognitive function, and sleep scores, and higher fatigue. Fatigue showed the strongest correlation with mental health outcomes, particularly with those screening positive for depression ( ρ  = 0.644, p  < 0.05). Conclusion: Mental health symptoms are strongly correlated with worse HRQoL outcomes in NTM-PD. These findings underscore the need for the implementation of routine mental health screening and interventions in NTM-PD care.
