Sleep-disordered breathing in patients enrolled in an inpatient stroke rehabilitation program

Arch Phys Med Rehabil. 2010 Apr;91(4):659-62. doi: 10.1016/j.apmr.2009.12.019.

Abstract

Objective: To report the prevalence of sleep-disordered breathing in an inpatient stroke rehabilitation unit and to explore correlations with functional status and health-related quality of life.

Design: Cross-sectional study.

Setting: Rehabilitation center.

Participants: Consecutive patients (N=45; mean age, 67+/-12y) (28 men) enrolled in inpatient rehabilitation after ischemic (84%) or hemorrhagic stroke (16%).

Interventions: Not applicable.

Main outcome measures: Overnight respiratory polysomnography was performed on all subjects. Interviewer-administered scales of sleepiness (Epworth Sleepiness Scale) and functional status (FIM, Barthel Index) were completed. Health-related quality of life was assessed by using a general questionnaire (Medical Outcomes Study 36-Item Short-Form Health Survey [SF-36]).

Results: Of the 45 subjects tested, only 4 (9%) had an apnea-hypopnea index of less than 10 per hour. The mean apnea-hypopnea index was 32.2 (19.4) per hour; most events were obstructive. There was no relationship between the respiratory index and the components of SF-36 (P values>.2).

Conclusions: There was a dramatically high prevalence of respiratory events in patients after stroke enrolled in an inpatient stroke rehabilitation unit. The awareness of this will influence patient evaluation and management.
