AB  - BACKGROUND: Poor sleep and immobility are common in patients in the medical
      intensive care unit (MICU) and are associated with adverse outcomes.
      Interventions to promote sleep and mobilization in the MICU are gaining
      popularity, but feasible instruments to measure their effectiveness are lacking. 
      Actigraphy may be useful for large-scale, continuous measurement of sleep and
      activity, but its feasibility in MICU patients has not been rigorously evaluated.
      OBJECTIVE: To evaluate the feasibility of continuous actigraphy measurement in
      consecutive MICU patients. METHODS: Wrist and ankle actigraphy data were
      collected for 48 hours in consenting MICU patients. Actigraphy-based measures of 
      estimated sleep and activity were summarized by using descriptive statistics.
      Agreement between wrist and ankle measurements was evaluated using Cohen kappa
      statistics (for sleep quantity) and intraclass correlation coefficients (for
      activity). RESULTS: Overall, 35 of 48 (73%) eligible patients were enrolled,
      including 10 requiring mechanical ventilation. Of these patients, 34 (97%)
      completed the 48-hour actigraphy period; 20 (57%) found the devices comfortable. 
      Wrist devices logged a mean (SD) of 33.4 (8.8) hours of estimated sleep (72%
      [19%] of recording period) and 19.6 (17.2) movements per 30-second epoch. Ankle
      devices recorded 43.2 (4.1) hours of estimated sleep (93% [7%] of recording
      period) and 5.1 (6.0) movements per 30 seconds. CONCLUSIONS: Uninterrupted
      actigraphy is feasible and generally well tolerated by MICU patients and may be
      considered for future large-scale studies. Wrist and ankle actigraphy
      measurements of sleep and activity in this setting agree poorly and cannot be
      used interchangeably.
