RESUMO
OBJECTIVES: One goal of early mobilization programs is to facilitate discharge home after an ICU hospitalization, but little is known about which factors are associated with this outcome. Our objective was to evaluate factors associated with discharge home among medical ICU patients in an early mobilization program who were admitted to the hospital from home. DESIGN: Retrospective cohort study of medical ICU patients in an early mobilization program. SETTING: Tertiary care center medical ICU. PATIENTS: Medical ICU patients receiving early mobilization who were community-dwelling prior to admission. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: A comprehensive set of baseline, ICU-related, and mobilization-related factors were tested for their association with discharge home using multivariable logistic regression. Among the analytic cohort (n = 183), the mean age was 61.9 years (sd 16.67 yr) and the mean Acute Physiology and Chronic Health Evaluation II score was 23.5 (sd 7.11). Overall, 65.0% of patients were discharged home after their critical illness. In multivariable analysis, each incremental increase in the maximum level of mobility achieved (range, 1-6) during the medical ICU stay was associated with nearly a 50% greater odds of discharge home (odds ratio, 1.46; 95% CI, 1.13-1.88), whereas increased age (odds ratio, 0.95; 95% CI, 0.93-0.98) and greater hospital length of stay (odds ratio, 0.94; 95% CI, 0.90-0.99) were associated with decreased odds of discharge home. Prehospital ambulatory status was not associated with discharge home. CONCLUSIONS: Among medical ICU patients who resided at home prior to their ICU admission, the maximum level of mobility achieved in the medical ICU was the factor most strongly associated with discharge back home. Identification of this factor upon ICU-to-ward transfer may help target mobilization plans on the ward to facilitate a goal of discharge home.
RESUMO
BACKGROUND: Intensive care unit (ICU) sleep disturbance is severe and potentially related to abnormal light and sound exposure. OBJECTIVES: To assess the prevalence of measures of light and sound disturbance in ICU patient rooms, and whether these could be modified by a sleep-promotion intervention. METHODS: This observational study with a before and after design for a quality improvement initiative surveyed environmental factors in ICU rooms at 01:00 08:00, and 12:00. Surveys assessed light usage, television usage, window shade position, and room door/curtain position. Factors were compared before and after an ICU sleep-promotion intervention. RESULTS: 990 (pre-intervention) and 819 (post-intervention) occupied rooms were surveyed. Pre-intervention, the prevalence of night-time factors included: bright lights on (21%), television on (46%), and room door open (94%). Post-intervention, more rooms had all lights off at night (41% v 50%, p = 0.04), and fewer rooms had open door curtains (57% v 42%, p = 0.001) and window shades (78% v 62%, p = 0.002). CONCLUSIONS: Disruptive environmental factors are common in the ICU. Some factors improve with sleep-promotion interventions.
