Study objectivesNocturnal oxygen supply will prevent the consequences of sleep-related hypoxemia (i.e. neurocognitive and health-related quality of life decline) in severe to very severe chronic obstructive pulmonary disease (COPD) patients presenting sleep-related oxygen desaturation. This decline will become similar to that seen in those severe to very severe COPD patients without nocturnal desaturation.
Ethics approval(s)Approved by the Institute of Health Assistance (Institut d'Assistència Sanitària) (IAS), Institutional Review Board (IRB) reviewed the protocol and reported its approval on 27/04/2004, reference number: CEIC-IAS 06/2004
Health condition(s) or problem(s) studiedCOPD with and without nocturnal desaturation
InterventionAll patients will receive standard care, but nocturnal desaturators will be randomized to receive oxygen during sleep or standard care only. Neurocognitive function, blood/urine analysis and electrocardiogram will be assessed at baseline and at 18 months. Health-related quality of life, lung function, six-minute walking test, nocturnal oxymetry and respiratory and sleep-related symptoms will be assessed at baseline and at six-month intervals.
Intervention typeOther
Primary outcome measureNeurocognitive function by means of a battery of tests:
1. Trail making test
2. Wechsler adult intelligence scale (WAIS)
3. Wechsler memory scale-revised (WMSR) test
4. Verbal fluency test
5. Rey complex figure test (RCFT)
6. Rey auditory verbal learning test (RAVLT)
7. National adult reading test (NART)
8. Repeatable battery for the assessment of neuropsychological status (RBANS)
9. Luria's premotor test performance
Secondary outcome measures1. Health-related quality of life (St. George’s respiratory questionnaire)
2. Anxiety (state-trait anxiety inventory [STAI])
3. Depression (Beck depression inventory [BDI])
4. Exercise capacity (walking test)
5. Sleepiness (Epworth scale)
6. Dyspnea (Medical Research Council [MRC] scale)
7. Diurnal oxygen and carbonic anhydride blood pressures
8. Nocturnal urinary norepinephrine
9. Exacerbation rate
10. Hospitalization days
11. Mortality
Overall study start date08/03/2006
Completion date07/03/2009
