Study information

Primary study designInterventional
Study designRandomised single blind trial
Secondary study designRandomised controlled trial
Scientific titlePrevention Of Morbidity In Sickle cell disease pilot phase
Study acronymPOMS
Study objectivesIn sickle cell anaemia, nocturnal oxyhaemoglobin desaturation is associated with low processing speed index, and this morbidity can be reduced with overnight auto Continuous Positive Airways Pressure (CPAP) and/or oxygen supplementation.
Ethics approval(s)St Marys Hospital Research Ethics Committee has approved the pilot phase of this study on the 25th September 2006 (ref: 06/Q0403/133).
Health condition(s) or problem(s) studiedSickle cell anaemia
InterventionOvernight auto Continuous Positive Airways Pressure (CPAP) with oxygen supplementation if mean overnight oxyhaemoglobin saturation is not more than 94% after two weeks of autoCPAP versus no treatment.
Intervention typeOther
Primary outcome measure(s)

Change in processing speed index.

Key secondary outcome measure(s)

1. Frequency of pain measured via SMS and pain diary
2. Adverse events e.g. headache, anorexia, weight loss, nausea, vomiting, reduction in steady state red or white cell count
3. Change in blood pressure
4. Number of omissions on Conners Continuous Performance Test
5. Change in Chervin sleep questionnaire
6. Change in Behaviour Rating Inventory of Executive Function (BRIEF)
7. Change in number of abnormalities (Adam's criteria) on Trans Cranial Doppler (TCD)
