Afferent Limb

Event Detection – Identifying the patient at risk Bedside Clinician Empowerment Education

• Calling Criteria• Recognition of the critically ill

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
