chronic critical illness
Definition
Chronic critical illness first
termed by Girard & Raffin in
1985 in an article titled “ to
save or let die?” pertaining to
patients who had failed to
wean from mechanical
ventilation for a prolonged
period of time in the intensive
care unit.
These patients neither
recovered nor died, but were
rather “stuck” in a chronically
ill state requiring continuous
care.
(Nelson et al., 2010; Image from Google Images)
Definition
o Chronic critical illness is a syndrome characterized by
neuroendocrine dysfunction, malnutrition,
multisystem organ dysfunction, and symptom
distress (Cox, 2011).

Neuroendocrine
and
inflammatory
response
Characteristics of CCI
Hallmark of CCI is an inability to be weaned from
prolonged mechanical ventilation (Cox, 2011).
There is a positive correlation between length of
mechanical ventilator (prolonged mechanical ventilation)
time and associated mortality with CCI.
Even after liberation from mechanical ventilator,
continued functional dependence key finding in those
with CCI (Nelson et al., 2010).
Characteristics of CCI
Mechanical ventilation 2
days- 4 weeks
Profound weakness
Alterations in body
composition
including:
Decreased muscle
mass
Anasarca
Increased adipose
tissue
Neuroendocrine changes
Decreased hormone
levels
Increased anabolism
(Nelson et al., 2010)
Increased susceptibility
to infections
Brain dysfunction
Coma
Delirium
Prolonged Immobility
Inability to communicate
Inducing stress,
anxiety, depression
for patient
(Adapted from Nelson, 2010)
Key Facts of CCI
Chronically critically ill ( CCI) accounts for ~ 5-10% all
ICU admissions.
CCI patients reach nearly ~90,000 discharges yearly.
Majority of patients > 65 years of age.
The number and severity of patients with CCI is expected
to continue to rise over the next ten years.
One year survival for those with CCI remains low
(between ~20-40%).
Financial burden associated with CCI is continually rising,
but can be lessened with appropriate transfer out of the
hospital ICU setting.
(Carson, 2005)
Economic Impact of Chronic
Critical Illness
Annually cost are estimated to be $24 billion
$76K-$2Mill. Per patient
The Critically ill only account for $7400-$24K
Ventilators as a whole account for 1/3 healthcare cost in
US hospitals
Requiring intubation nearly double individual healthcare
cost
Number of those requiring mechanical ventilation is expected to
triple by the year 2020
Only 5-10% of ICU patient account for 30-50% of
resources used
ECF play an important role in reduction of length of stay,
however costs remain high.
(Weinck & Winkelman, 2010)
(Adapted from Carson, 2012)
Populations at risk
Post-op complications from major cardiac or abdominal surgeries
Trauma patients
Patients with acute exacerbation of chronic lung disease
Patients with previous diagnosis of neurologic disease
Patients with multiple co-morbidities ( especially cardiac, pulmonary, and renal
disease)
Complications leading to prolonged mechanical ventilation time
Patients with neuromuscular abnormalities
Greatest risk factor: Patients with SIRS (systemic inflammatory response
syndrome) and/or sepsis
(Carson, 2005)
Acute versus Chronic Critical Illness
ACUTE
Elevated ACTH,
cortisol, and
prolactin levels
Increase growth
hormone levels
Decreased ACTH
levels
Decrease thyroid
stimulating hormone ,
T3, & T4
Mechanical Ventilation
>21 day, growth
hormone decreases
Neuroendocrine
changes are often
maladaptive causing
protein deficiencies,
insulin resistance,
hypertriglyceridemia,
& decrease immune
function
Decreased
thyrotropic and
gonadotropic
hormone levels
Neuroendocrine
changes are
adaptive to
preserve vital
organs and
function
CHRONIC
(Carson, 2005)
Hormones
ACTH- releases cortisol
Typically released in times of
stress
Associated with
hyperglycemia by
gylcogenesis, increased
gluconeogenesis
Assists in breakdown of
amino acids and protein,
increasing lactate
Stimulates release of
triglycerides, free fatty acids
Impaired wound healing
(Shimmer & Funder, 2011;Image from Google Images)
Pathophysiology Acute Phase
Elevation in adrenocorticotropic hormone (ACTH),
cortisol, and prolactin levels
Decrease in thyrotropic and gonadotropic hormone levels
Pituitary gland increases secretion of growth hormone in
a steady pulsing pattern controlled by gonadotropin
releasing hormone (GNRH)
The alterations in hormones enhance the body’s
response to maintenance of vital organ and immune
function
(Carson, 2005)
Pathophysiology- Chronic Phase
Decrease in ACTH along some anterior pituitary hormone
levels
Elevated cortisol level continues
Loss of thyroid stimulating hormone (TSH) leading to a
decrease triiodothyroxine (T4) and triiodothronine (T3)
Decrease in both excretion and pattern regulararity of
GH secretion
Alterations in hormones are detrimental to body’s
function leading to decrease in protein production and
progressive protein breakdown

Management of Chronic Critically Ill
Patients
Image from Google Images
Management of CCI Patient
Multi-factorial
Prevention
• Mechanical Ventilator Weaning/Mobility
• Nutrition
• Functional & Cognitive Recovery
• Preventing Complications
• Care Models
• Ethics
(Carson, 2005)
Management of CCI
Requires an interdisciplinary approach
Consistency of providers proves beneficial
Involves patient, their family, ICU physician, ICU staff (RN,
RT, & Social work)
May also include chaplain, palliative care, ethics committee
Patient and family should know the caregivers prior to any
potential family meeting
With prior relationship care team members may be able to
recognize change in patient and family’s emotional status more
quickly.
(Nelson & Hope,
2012).
Recognize those at risk…
ProVent Score mortality prediction model
Looks at 4 variables to identify patients at high risk for one
year mortality
Age
Platelet count
Hemodialysis
Vasopressor Requirement
Used to help clinicians establish prognosis
Is not reliable for functional outcomes, therefore doesn’t
provide much reassurance for family members
(Carson, 2012).
ABCDE Bundle
Functional & Cognitive Recovery
ABCDE Bundle was initiated in response to complication secondary to long
term mechanical ventilation, delirium, and exacerbated weakness
ABCDE= spontaneous awakening and breathing trials coordination,
delirium monitoring and management, and early mobility
Based on three main principles
Improved communication & collaboration of the healthcare team
Standardize care processes
Break the cycle of over sedation &
prolonged mechanical ventilation.
(ABCDE Bundle, 2012; Balas et
al., 2012 ).
ABCDE Bundle
A= awaken patient every day, sedation weaned
Nursing implement sedation protocols and algorithms
Richmond agitation and sedation scale (RAAS)
B= breathing
Spontaneous breathing trials (SBT’s)
Most institutions these trials occur daily
Certain parameters must be met for patients to “qualify”
FiO2 < 60%
SBP > 90 mm Hg, not actively titrating vasopressors
Peep < 8
SBT’s have been shown to
Decrease ventilator time
Decrease length of ICU and overall hospital stay
decrease PTSD from chronic critical illness
C= coordination
Awakening and breathing trials should be performed together
Decreased ventilator time
Decreased coma
Decreased ICU stay when SAT and SBT’s coincide
(Balas et al., 2012).

D= Delirium monitoring management
Confusion Assessment Method (CAM)
Based on four categories: fluctuating course of

consciousness, and disorganized thinking.
Intensive Care Delirium Screening Checklist
Based on 8 categories similar to CAM.
E= Early Mobility
PT/OT, out of bed, ambulation
Mobility progression protocols
Usually based on similar criteria to SBT’s
(MOVE)
Myocardial stability = (no arrhythmia or
recent MI)

Research Walk To Wean
Walk to Wean
104 patients were studied and
randomized electronically
49 intervention: Daily sedation
vacation and early exercise &
mobilization
55 control: Daily sedation
vacation and physician ordered
therapy
Primary Outcome
Independent Status:
Performing six activities of
daily living & walking
Secondary Outcome
Number of Delirious days
Number of Ventilator free
days in 28 day period
(Schweickert, 2009; Image from Google Images)
Research Walk to Wean cont.
Walk to Wean Trial Outcomes
Therapy only discontinued for 4
patients related to instability
Primary Intervention Group
Improved outcomes in functional
status (59% vs 39%)
Secondary Intervention Group
Fewer delirium days (2 days vs. 4
days)
Fewer ventilator days
vs. 23.5 days)
(21.1 days
(Schweickert, 2009; Image from Google

Tracheostomy: To do or not to
do?
Advantages
Disadvantages
Timing/Indications
Decannulation
•Decreased ventilator dependent time
•Shorter ICU stay
•May be an unnecessary procedure if done too
quickly
•Bleeding, infection
•Fistula formation
•Failure to wean from mechanical ventilation (10-14
days)
•Inability to handle excessive secretions
•Neurologic dysfunction
•Spontaneous breathing trials via tracheostomy
mask
•Assess for airway swelling and inflammation prior
to decannulation
(Saint, Madding, Calfee, Kolwaski, Kresn 2010; O’Conner & White, 2010)
Criteria for Decannulation
The disease process that resulted in the need for a
tracheostomy should be resolved
Patient should be alert and able to follow commands
Effective cough
Able to swallow and manage own secretions
Airway patency
Evaluate using a mirror exam of the larynx or by direct
fiberoptic endoscopy
Observe patient’s respiration when tube is occluded
Plugging
(Yu, 2012; Conner & White, 2010)
Nutrition
Malnutrition common in ~ 40% of critically ill patient
Goal in CCI is to avoid malnutrition (over/under nourished)
Aimed at prevention of body mass loss, prevention of tissue and immune
response alteration
Protein-calorie malnutrition along with decreased albumin levels directly
links to elevated levels morbidity & mortality
Monitoring of Prealbumin correlates to current nutritional status, where
albumin is related to long term nutritional status
Nelson & Hope, (2012); Schulman &
Mechanick (2011)
Nutrition
Underfeeding
Improper protein levels increase
metabolic consumption leading
to less energy reserves
Linked to increase risk of
infection, longer hospital stays &
mechanical ventilation, elevated
risk of death
Overfeeding
Improper Carbohydrate, lipid,
and protein levels lead to
increased organ dysfunction
secondary to elevated metabolic
demand
Similar to effects of underfeeding
along with liver/renal failure
Schulman & Mechanick (2011).
Nutrition
Refeeding Syndrome
Occurs following initiation of nutrition in severely malnourished patient
Can lead to altered diaphragmatic function
Decreased levels of insulin & glucagon
Leading to alteration of metabolism
Increased lipolysis, free fatty acid oxidation, & ketones
Worsening of electrolyte abnormalities
Due to depletion of already low levels of phosphate, insulin, and thiamine
Goal with feeding:
20-25 kcal/kg/day
AjBW= IBW + [(ABW-IBW) – correction factor]
(Schulman & Mechanick 2011; Image from Google Images)
Nutrition
ACNP should
Complete detailed evaluation of nutritional status and
protein wasting
Checking CBC, ammonia, hgbA1c, albumin/pre-albumin
Thyroid function studies, urea nitrogen
Optional testing
Testosterone, iron studies (ferritin, iron, transferrin saturation,
iron binding capacity),serum cortisol
(Mechanick & Brett, 2005; Ogilvie & Fitzsimons, 2012;

Functional Cognitive Recovery
Physical/Occupational Therapy
Walk to wean
Early Mobility (ABCDE Bundle)
Avoid use/overuse of Benzodiazepines
Recommend use of new age antipsychotics such as
Haloperidol
Long Term Cognitive Recovery
Neuro-Cognitive Dysfunction
Coma and delirium results in recurrent psychiatric and
cognitive behavior changes which can be persistent long
after discharge
Impairment can be cause by:
Degree of illness
Medications
Inability to communicate with providers
Psychological needs not being met
Pain, Thirst, Dyspnea
Can lead to anxiety and depression
Alterations in sleep patterns
Approximately 15-20% suffer from post traumatic stress in
relation to their CCI
Wienck & Winkelman, 2010
Complications
Triple threat risk of
infection
Barrier breaches: IV
catheters & Skin
breakdown
Treatment
Hand hygiene
Exposure to resistance
organism within acute
care hospital setting
Contact precautions
“Immune Exhaustion”
Limit use of antibiotics
Recent critical illness
and history of comorbidities
(Carson, 2005; Images from Google Images)
Early removal of invasive
catheters
Maintain skin
Complications from CCI
Deficit
Reduction
Act of
2005
• Mandated strict compliance aimed at
prevention of hospital acquired infections
• NO reimbursement for conditions such as:
• Urinary Tract Infection
• Central Line Associated Blood Stream
Infection
• Decubitus Ulcers
• Preventable Events (Blood incompatibilities)
• Falls
• Glycemic Control
• Post operative Infection
• Deep Venous Thrombosis
• If not documented as present on admission
(www.cms.gov, 2012)
Nosocomial Infections
Prevention is Key
Pressure Ulcers
CLABSI (central line
associated blood
stream infection)
CAUTI (catheter
associated urinary
tract infection)
(Wachter, 2012)
•Only way to prevent these infections is not to place lines or
have patients who are immobile (impossible)
•Adequate nutrition (protein)
•Early mobility
•Incontinence care
•Often needed for vasopressors, IV antibiotics, anti-arrhythmic
•Sterile technique during line placement and dressing changes
•Remove as soon as possible
•Nurses need an order to place a foley catheter
•When needed, remove as soon as possible
Ethics
Autonomy
Presumption patient can make own decisions
Autonomy versus decision-making capacity
Cognitive function and delirium most influence patient’s
ability to make decisions in CCI.
A research study found that patients who are hospitalized
with poor physical functioning have cognitive function level
less than that of a 10 year old
(Teneli et al., 2010; Images from Google images)
Ethics
Justice
In the United States, critical care (ICU) accounts for 20% of
all health costs and 1% of the gross national domestic
product (14% of GDP is spent on healthcare)
Barriers to reducing cost in ICU
Fixed costs
Inability to accurately predict ICU mortality
Inability to predict unexpected outcomes
(Luce & Rubenfeld, 2002, Connors & Dawson, 1995;
Image from Google Images)
Ethics/Justice Study
SUPPORT is a landmark study to understand prognoses
and preferences for outcomes and risks of treatment.
The study followed a large group of critically ill patients
with a six month predicted survival probability of 52%.
SUPPORT identified several areas for improvement:
Significant lack of communication, only 47% of physicians
knew if their patients preferred CPR
Establishing DNR orders for terminal patients earlier. Many
patients that died spent at least 10 days in the ICU
comatose, on mechanical ventilation, in pain with 46% of
DNR orders written two days before death.
Most expensive patients to treat were those classified as
medium-risk patients on admission, those who had a 5170% estimated two month survival and those with
unexpected outcomes
(Luce & Rubenfeld, 2002, Connors & Dawson, 1995)
Ethics
Non-Maleficence & Beneficence
Non-Maleficence deals with idea of doing no harm and
beneficence deals with the idea of doing good
In a survey of critical care physicians 87% reported they
felt futile care had been delivered in the ICU in the past
year
Critical care physicians reported believing 11% of
patients receiving care that was futile and 8.6 % were
receiving care that was highly likely to be futile
Of the 11% of patients receiving care believe to be futile
68% died before discharge and at six months there was an
85% mortality rate
(Huynh et. al., 2013).
Ethics-Moral Distress
Moral Distress
Research shows that the most distressing phenomenon
reported by caregivers in end-of-life care is the delivery of
futile care, organ donation and pain management
Some nurses report experiencing moral distress weekly
Research shows a positive correlation between knowledge
of moral ethics and reported distress over ethical issues
Futile care
Factors Influencing Perception Healthcare is Futile:
burden outweighed benefit
treatment did not align with patient’s goals
Death was imminent
(Browning, 2013,Weigand & Funk, 2012)
Palliative
Care
Ongoing, highly proactive communication with patient
and families
Knowledge/Discussion of Living well
Acknowledges belief systems
Lessens family burden
Acknowledges spiritual, physical, & emotional need
Promotes long-term health and well being
(Nelson, Cox, Hope, & Carson, 2010; Image from Google images)
The Patient’s Perception
Self-reported symptom experience of
critically ill cancer patients receiving
intensive care
Objective: To characterize the symptom experience
of 100 ICU patient’s with the diagnosis of terminal
cancer and high risk for hospital mortality.
Measurements: Patients’ self-reports of symptoms
using the Edmonton Symptom Assessment Scale
(ESAS), and ratings of pain or discomfort associated
with ICU diagnostic/therapeutic procedures and of
stress associated with conditions in the ICU.
(Nelson et al., 2001)
Results
Hospital mortality for the group was 56%
100% provided symptom reports
55% and 75% reported experiencing pain,
discomfort, anxiety, sleep disturbance, or
unsatisfied hunger or thirst that they rated as
moderate or severe.
Depression and dyspnea at these levels were
reported by approximately 40% and 33% of
responders.
Significant pain, discomfort, or both were
associated with common ICU procedures but well
managed
Inability to communicate, sleep disruption, and
limitations on visiting were particularly stressful
among ICU conditions studied.
Nelson et al., 2001)
Family Burdens
High rates of:
Depression
Financial hardship
“Care-giver overload”
Studies have shown:
Depression is more severe in
families
