简要总结
Obstructive sleep apnea (OSA) is associated with impaired stroke recovery. Treatment with continuous positive airway pressure (CPAP) may prevent this but is limited by poor adherence. In this study, the investigators enrolled eligible stroke patients undergoing inpatient rehabilitation (IPR) into an intensive CPAP adherence protocol (iCAP) with an aim to increase tolerance and adherence to auto-titrating CPAP (APAP).
详细描述
The SCOUTS (Stroke and CPAP Outcome Study 2) was a single-arm, open-label study performed at 2 IPR units of the University of Washington. Eligible stroke patients undergoing IPR were provided an intensive CPAP adherence protocol (iCAP) to increase tolerance and adherence to auto-titrating CPAP (APAP). The iCAP included patient education and encouragement, device adjustments, close monitoring of adherence and a 3-night run-in period of APAP to identify those patients who 1. have OSA and 2. have APAP tolerance-- defined as participant willingness to continue APAP during IPR and over the 3-month treatment period. If both criteria were met, APAP treatment with iCAP continued during the rehabilitation stay and over a 3-month period. The goal of the intervention was to achieve 50% of subjects meeting APAP adherence (an average ≥ 4 hours per night) over the 3-month treatment period. The investigators evaluated if demographic, co-morbid or stroke-specific factors predicted APAP adherence and assessed the relationship between APAP adherence and neurological recovery from stroke.

入选标准
- •Adult patients admitted after acute ischemic or hemorrhagic stroke to one of two inpatient rehabilitation units
排除标准
- •The investigators will exclude participants if: their stroke was a subarachnoid hemorrhage or due to a secondary cause (vascular malformation, vasculitis, brain tumor, head trauma, or predisposition to bleeding); they have active CPAP use, advanced chronic lung disease requiring supplemental oxygen, heart failure (NYHA class III or IV); or they needed a nasogastric feeding tube.
结局指标
主要结局
3-month CPAP Adherence
时间窗: 3 months
Number of participants who continue CPAP after the run-in period who have acceptable adherence at 3 months, defined as using CPAP for an average of at least 4 hours a night on at least 70% of nights.
次要结局
- CPAP Tolerance(Upon discharge from rehabilitation unit, typically at 14-21 days from CPAP initiation)
- Change in the Motor Functional Independence Measure (FIM) Subscore(Between admission to rehabilitation unit and between 3-4 months following enrollment)
- Change in the Cognitive Functional Independence Measure (FIM) Subscore(Between admission to rehabilitation unit and between 3-4 months following enrollment)
- Change in NIH Stroke Scale(NIHSS scores were obtained in-person on enrollment and at 90 ± 7 days from enrollment.)
