Invasive home mechanical ventilation: living conditions and health-related quality of life

Abstract

Background: The number of patients with invasive home mechanical ventilation (HMV) following unsuccessful weaning is steadily increasing, but little is known about the living conditions and health-related quality of life (HRQL) in these patients.

Objectives: To establish detailed information on living conditions and HRQL in patients with invasive HMV.

Methods: The Severe Respiratory Insufficiency Questionnaire (SRI) was used to measure specific HRQL aspects in addition to patient interviews on individual living conditions during home visits.

Results: Thirty-two patients with lung disease, most prominently COPD (n = 18), and neuromuscular disorders (n = 14) were included. The overall mean SRI summary scale score (range 0-100) was 53 ± 16, with a broad range amongst individuals (23-86). Neuromuscular patients were younger than those with lung diseases (49 ± 18 vs. 67 ± 11 years; p < 0.005), and although they had a higher nursing dependency and fewer comorbidities, they tended to have higher (better) SRI summary scale scores (58 ± 16 vs. 48 ± 15; p = 0.092). Living in a private home compared to living in nursing facilities did not influence the SRI scores.

Conclusions: Patients undergoing invasive HMV primarily following unsuccessful weaning reported an individual HRQL which, when taken together, was highly heterogeneous and ranged from very good to extremely bad. Older patients with COPD and more comorbidities are likely to have a worse HRQL than neuromuscular patients, while the living situation does not influence the HRQL.
