Intensive care unit (ICU) patients on respirators are at high risk for preventable pulmonary complications (PPC). Turning these patients from side to side may reduce PPC, but carries the burden of decreases in blood pressure and oxygenation. The investigators hypothesize that there will be no difference in PPC or adverse events when ICU patients on respirators are turned by nurses or by an automated turning bed.

Condition Intervention
Pneumonia, Ventilator Associated
Other: Manual turn
Device: kinetic therapy bed

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Single Blind (Outcomes Assessor)
Primary Purpose: Treatment
Official Title: Multi-site Randomized Clinical Trial of Horizontal Positioning to Prevent and Treat Pulmonary Complications in Mechanically Ventilated Critically Ill Patients

Further study details as provided by Sandra K. Hanneman, The University of Texas Health Science Center, Houston:

Primary Outcome Measures:
  • Incidence of Pulmonary Complications. [ Time Frame: Participants were followed for the duration of ICU stay, an average of 10 days. ]
    Number of participants who did not have preventable pulmonary complications (PPC) on pre-study chest radiograph (CXR) and developed PPC during the study period. Pearson Chi-Square test used to test significance of difference between turning groups.

Secondary Outcome Measures:
  • Mechanical Ventilation Duration. [ Time Frame: Participants were followed for the duration of mechanical ventilation, an average of 5.5 days. ]
    Days on mechanical ventilation, from initiation to withdrawal of mechanical ventilation

  • ICU Length of Stay. [ Time Frame: Participants were followed for the duration of ICU stay, an average of 10 days. ]
    Time in days from study ICU admission to study ICU discharge or death

  • ICU All-cause Mortality. [ Time Frame: Participants were followed for the duration of ICU stay, an average of 10 days. ]
    Death from any reason between admission and discharge from study ICU

  • Turning-related Events [ Time Frame: Participants were followed for the duration of time on protocol, an average of 3.5 days. ]
    Non-serious adverse events that occurred during the time of rotation in the kinetic therapy bed group and during lateral rotation to right or left position in the manual turn group

Enrollment: 16
Study Start Date: September 2007
Study Completion Date: September 2011
Primary Completion Date: September 2011 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Kinetic Therapy Bed
Kinetic Therapy Bed: Continuous automated turning to 45 degrees with head of the bed elevated 30 degrees or more for up to 7 continuous days
Device: kinetic therapy bed
Continuous, automated turning to a maximum of 45 degrees in the lateral positions while the patient is receiving mechanical ventilation
Other Names:
  • CLRT (continuous lateral rotation therapy)
  • KT (kinetic therapy)
Active Comparator: Manual Turn
Manual Turn: lateral rotation every 2 hours from back to left to back to right to back, with >/= 45 degree lateral rotation angle and 30 degree head of bed elevation
Other: Manual turn
Manual turn from side to back to side every 2 hours by nurses while patient receiving mechanical ventilation
Other Name: Lateral rotation

Detailed Description:
The purpose of this pilot study is to test the feasibility of two turning protocols and study procedures for a multi-site randomized clinical trial to evaluate efficacy and safety of horizontal positioning interventions to reduce pulmonary complications in mechanically ventilated critically ill adult patients. The hypothesis of the randomized controlled trial (RCT) is no difference in pulmonary complications between manual, 2-hourly lateral rotation to > 45 degrees (control), and continuous automated turning to 45 degrees (experimental) groups.
