Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Rate of respiratory and functional decline, mortality and RTIs. | — |
Secondary
| Measure | Time frame |
|---|---|
| • Examine the relationships between rates of decline in respiratory function measures and prognosis / life expectancy / NIV initiation. • Examine the relationship between respiratory tract infection morbidity and respiratory function. • Examine the relationship between respiratory function and respiratory impairment symptoms. • Correlate rates of decline in respiratory function measures and overall functional decline using the ALS functional rating scale (ALSFRS-R). • Examine the respiratory tract infection morbidity rates. • Examine the predictive value across a range of respiratory function constructs to predict carbon dioxide pressure (PCO2). • Explore the potential relationships between other demographic characteristics, baseline variables, and outcome measures as defined above | — |
