INTRODUCTION
• JCAHO, CMS, and FDA minimize use of physical
restraint in patient care.
• NQF: restraint is a nurse sensitive quality indicator.
• Majority of physical restraint use in hospitals is in
critical care.
• ICU RNs & MDs use physical restraint to prevent
patient-initiated therapy disruption of medical
devices; less often to keep from falling out of bed.
INTRODUCTION
• Few studies have examined rate, contexts or
consequences of therapy disruption and/or
association with physical restraint.
• Society of Critical Care Medicine: more
knowledge is needed to enable an evaluation
of risk-to-benefit ratio of restraining versus
nonrestraining interventions in ICUs
OBJECTIVES
• To describe the rate and contexts related to
TD in ICUs
• To examine factors associated with TD rates
in ICUs
• To describe the consequences of ICU TD to
patient and staff
METHODS
• Design: Prospective prevalence
• Settings: 49 adult ICUs from 39 hospitals
selected at random from 6 geographic areas of
U.S; average daily census > 99

Variables
• Outcome Variable:
disruption
Types and rate of therapy
– Rate = (# therapy disruption episodes/total patient days) x
1000.
• Unit-Level Contextual Variables: Census,
proportion of days: men, physical restraint (excludes
side rails), ventilator, and elderly.
• Patient-Level Contextual Variables:
Demographics, cognition, sedating medications,
presence of restraint at time of disruption.
Variables (continued)
• Patient Consequences: Adverse events as direct
consequence of TD (e.g., hemorrhage)
• Staff Consequences: Unprotected exposure to
body fluids, violence or physical harm.
• Resource Consequences: Additional resources
(procedures, therapies) as direct consequence of
the therapy disruption
DATA COLLECTION
PROCEDURES
• 2003 - 2005
• Trained ICU RNs, daily rounds
• Therapy disruption ascertainment
– nurse initiated reporting card
– daily interview with nurses
– chart abstraction.
• Chart abstraction to describe disruption
episode, patient contextual variables, and
consequences.
RESULTS
• ICU Profile: 49 ICUs: size 8 – 42 beds:
26 General, 12 MICUs, 11 SICUs
• Number of Patient-Days:
49,482
Unit range: 172 – 2,155 patient-days
Rates of TD Episodes and Devices
• # patient episodes with one or more TDs: 1,097
TD episode rate: 22.1 episodes/1000 days (0 to 102.4)
• Rates by ICUs:
- General = 23.6
MICU = 23.4
Surgical = 16.1
• # devices terminated/disrupted: 1,638
• TD device rate: 33.1 devices/1000 days (0 to 168.9)
• Rates by ICUs:
– MICU = 39.8
General = 33.1
Surgical = 26.0

transfusions)

CONCLUSIONS
• TD not rare but varies among units
• No significant relationship by proportion of
men, elderly, ventilator, or use of physical
restraint
• Most experience no harm, but clinically
significant number incur minor to moderate
harm and/or need device restarted
• Further study to examine patient- and unitrisk factors
