Abstract

Objectives The study aims to assess the prevalence of anxiety, depression and the quality of life among patients with chronic respiratory failure and the changes in anxiety and depression scores after initiating domiciliary oxygen. Design and setting Prospective, single-centre cohort study conducted in a tertiary care hospital in India. Participants Patients of Indian origin with chronic respiratory failure who visited the hospital where domiciliary oxygen is indicated were included in the study. Patients with acute respiratory failure on a mechanical ventilator, haemodynamic instability and already-diagnosed psychiatric conditions were excluded from the study. Interventions Patients who met the inclusion criteria were assessed at baseline, at 3 and 6 months, for anxiety and depression using the 7-item Generalised Anxiety Disorder questionnaire (GAD-7) and 9-item Patient Health Questionnaire (PHQ-9). Quality of life was evaluated using the WHO Quality of Life-BREF questionnaire. Primary and secondary outcome measures The primary outcome is the proportion of patients with chronic respiratory failure having depression and anxiety and assessing the changes in anxiety and depression scores after initiating domiciliary oxygen. The secondary outcome is the change in health-related quality of life (HRQOL) of patients on domiciliary oxygen. Results 121 patients who met the inclusion criteria were included in the study. Of 102 patients who completed the study, 36.2% (n=37) had anxiety and 44.1% (n=45) had depression at baseline. There is a worsening trend in the mean GAD-7 (p=0.003) and PHQ-9 score (p=0.015) in patients over 6 months while on domiciliary oxygen. HRQOL is poor in all the domains at baseline, and there is a progressive worsening during follow-up while on oxygen. Conclusions The worsening trend in anxiety and depression in patients after initiating domiciliary oxygen may be related to social isolation, restricted mobility, economic issues, addictions and frequency of exacerbations. Screening for psychological problems in these patients at baseline and on follow-ups helps early detection, and prompt intervention could improve the quality of life and survival.
