Afferent Limb
Event Detection – Identifying the patient at risk Bedside Clinician Empowerment Education
• Calling Criteria• Recognition of the critically ill
6
Efferent Limb
Structure varies with jurisdiction U.K. – Outreach Australia – MET U.S.A. – MET, Hospitalists, RRT’s Canada – CCRT’s
• MET during day• Outreach at night with Intensivist backup
Patient Assessment & Treatment

Administrative Limb
LeadershipImplementation & PlanningData Collection & Analysis & Feedback
Design feedback mechanisms to the team and to the teams response areas
Track data to improve utilization of the team
Why bother??
A code does not occur out of the “Blue”

Cardiac arrests over 4 months• 84% had documented clinical deterioration within 8
hours pre-arrest
10Recognizing clinical instability in hospital patients before cardiac arrest or unplanned admission to intensive care. A pilot study in a tertiary-care hospital.Buist MD, Jarmolowski E, Burton PR, Bernard SA, Waxman BP, Anderson J.
Retrospective review, over one year of all: cardiac arrests unplanned ICU admission
Median duration of instability 6.5 hours prior to Critical Event
Med J Aust. 1999 Jul 5;171(1):22-5
Prospective confidential inquiryReviewed 100 consecutive patients admitted to ICU
Revealed that up to 41% of ICU admissions could possibly be avoided.
Related to:failure to appreciate alterations in the ABC’s and delay in ICU Consultation
12
Unexpected deaths and referrals to intensive care of patients on
general wards. Are some cases potentially avoidable?
6 months review of all hospital deaths, unplanned ICU admissions
4% of deaths were potentially avoidable, early warning signs not appreciated.
ICU Admissions 32% of which clinical deterioration was not appreciated ICU mortality higher 52% vs 35%

16Rationale
There is time for intervention The evolution of physiological deterioration is relatively slow.
There are warning signs Clinical deterioration can be detected utilizing common vital signs
There are effective treatments Early Goal Directed Therapy ACS therapy Oxygen, NIV for COPD, CHF
Many critical interventions are time dependant. Trauma Severe Sepsis ACS CVA
Expertise exists and can be deployed
17
Critical Care Response Teams in Ontario are:
A systematic approach to the early identification and facilitation of resuscitation of in-patients at risk of deterioration.
A way to provide Comprehensive Critical Care Services
Prophylactic interventions• Follow-up of patients recently discharged from the ICU to prevent
readmission• Rounds on high-dependency units
18
continued …
A way to provide critical care educationTeaching nursing unit personnel
Signs and symptoms of an at risk patient Utilization of calling criteria
Teaching medical students and residents how to recognize and resuscitate the acutely ill patient
A way to Support and Coordinate the care of patients
Assistance with end-of-life decision discussion Improving communication between the ICU and other units

Dose Response Curve
Vol 9 No 6 ResearchLong term effect of a medical emergency team on cardiac arrestsin a teaching hospitalDaryl Jones, Rinaldo Bellomo, Samantha Bates, Stephen Warrillow, Donna Goldsmith, Graeme Hart, Helen Opdam and Geoffrey Gutteridge
Critical Care 2005, 9:R808-R815
17 MET calls per 1000 inpatient admissions is associated with
reduction in cardiac arrest rate of 1 per 1000 admissions
25
How does this compare to MERIT?
6.3 – 1.2 = 5.1 MET calls/1000
26
Predicted impact on Cardiac Arrests of 5 MET
calls = 0.3/1000

Implementation PrinciplesLocal leadership, Central CoordinationStrong Local Leadership:
MD lead, co lead nurse leader or RRT leader, Administrative Support
Navigation of the Cultural, Sociologic, Political Mine FieldsCentral Coordination
Support Local Leadership!!! Coordinating Communication between sites Identify Hospitals Define Team Structure Defining Roles and Responsibilities Identification of Accountabilities Data Analysis & Feedback

Timeline for CCRT Project
Phase I – Preparation and team development, training and marketing. May 2006 – Oct 2006
six months 284 RN’s and RRT’s trained – wonderful
collaboration between local and central leadership Development of a CRI CCRT Course
Phase II – Preceptorship. Nov 2006 – Jan 2007 8 hour day – limited service consolidation of training, marketing twelve weeks
III – 24/7 service began January 29, 2007
