MBS: Challenges
• Number of appointment times
12 Victoria Hospital
11 University Hospital
• Wait times
• Limited times
• Physician consent

NPO: A Tough Sell
• For the patient:
Patient quality of
life
Tube feeding and
equipment
Nursing time
“Burden” of care
Discharge
destination and
timing
• For the team:
“This is holding up
discharge”
“How are we going to
give medications?”
“If he is aspirating, can
it be
tolerated?”

How were we going to solve this?

Systems Thinking
“Systems thinking organizes complexity into a
coherent story that illuminates the causes of
problems and how they can be remedied in
enduring ways” ~ Peter Senge
12
Systems Thinking 101
• “Integrative thinkers build models rather than choose
between them
• Consider customers, employees, competitors,
capabilities, cost structures, industry evolution, and
regulatory environment
• View the problem as a whole, rather than breaking it
down and farming out the parts
• Creatively resolve tensions without making costly
trade-offs, turning challenges into opportunities"

Approval…What Next?
• Finding equipment Request for tender
Review of equipment
Procurement of a FEES system
• Establishing a process Nasendoscopy (Delegation vs. Directive)
Nasendoscopy training…where, when, how, with whom
FEES: procedures and documentation format
• Executing the training Use of and transition to independence
• Selecting the paradigm Autonomy and efficiency
17
Medical Directive
• Education and skills to complete nasendoscopy
• Indications and contraindications
• Risks, complications and solutions
18
Where Are We Now?
• All SLPs achieved competency between September 2012 - January 2013

CANADIAN BEST PRACTICE STROKE
GUIDELINES
Patient has to be screened within first 24 hours of admission (Evidence Level C)
Instrumental assessment should be performed on all patients with high risk for aspiration or based on bedside swallowing assessment , stroke location (brainstem stroke etc.) or other clinical features (e.g., multiple strokes etc.) (Evidence Level B)
The decision to proceed with tube feeding should be made within 72 hours/3 days of admission in collaboration with patient, family or Substitute Decision maker and inter-professional team. (Evidence Level B)

FEES IN ACUTE STROKE
DYSDYSPHAGIA AND PNEUMONIA The reported incidence of dysphagia in acute stroke with
instrumental assessment is 64% to 78% . (Martino et.al 2005)
Incidence of pneumonia in acute stroke 16% to 19% (Martino et.al 2005)
The risk of pneumonia dysphagia > without dysphagia, dysphagia +confirmed aspiration > dysphagia without aspiration (Martino et.al 2005)
> 3 fold increase in pneumonia risk in stroke patients with dysphagia (Martino et.al 2005)
23
FEES IN ACUTE STROKE
SENSITIVITY AND SPECIFICITY
Good inter- and intra-rater reliability between FEES and MBS on Rosenbek Penetration and Aspiration Scale (Kelly et al, 2007)
Incidence of pneumonia was significantly lower with FEES than MBS in stroke patients (Aviv, 2000)
FEES has better outcome (behavioral and dietary) in stroke as it readily identifies fatigue of the pharyngeal phase and effect of fatigue (Aviv, 2000)
24
FEES IN ACUTE STROKE
SAFETY
FEES could be performed within 48 hours of onset of stroke symptoms
>80% of patients reported no or mild discomfort during FEES
(Warnecke et.al, 2008)

FEES IN ACUTE STROKE
AADVANTAGES OF FEES
Immediate and repeated assessments
Better visualization and information regarding sensory/afferent component compared to MBS (Aviv 2000)
Can be used as a bio-feedback tool
Able to assess secretion management
Visualization of anatomic soft tissue , anomalies (e.g., vocal cord paralysis etc.)
Portable to bedside
Test patients who are difficult to position or transport

FEES TRUISMS

Discharge Facilitated
CASE STUDY 1 • 71 year old female with history of kyphosis from NH
• Right Middle Cerebral Artery (MCA) stroke, dense left hemiplegia,
unilateral Upper Motor Neuron (UMN) dysarthria on Thursday night
• Not a TPA candidate
• Failed dysphagia screening due to left facial droop
• Seen by SLP Friday a.m. for a clinical swallowing assessment -
inconsistent clinical signs of penetration/aspiration therefore NPO
recommended
• Kyphosis preclude positioning for an MBS
• Also, no MBS slot until Tuesday
• FEES completed Friday afternoon – patient initiated on a pureed solids
with regular thin liquids
• NG tube was avoided
• Discharged to stroke rehab – day 5

Bio-Feedback Tool in Treatment
CASE STUDY 2 • 55-year-old man post brainstem stroke with subsequent
tracheostomy due to aspiration of secretions
• Admitted to the ICU
• Dysphagia managed by nasogastric tube
• Able to follow directions and participate in therapy to rehabilitate the swallow
• Repeated FEES studies completed with the goal of providing biofeedback/visualization
• First step, learning to swallow secretions and utilizing a volitional cough to laryngeal vestibule
• Decannulation in one week with improvement in secretion management
• Second step, within two week, patient learned chin tuck maneuver and initiated a full fluid diet
• Nasogastric tube removed
29
The Story So Far….
30
Questions
1. How has FEES influenced the number of
patients receiving MBSs?
2. How has FEES influenced the number of
swallowing referrals?
3. How has FEES impacted the use of
instrumental assessments?
4. How has FEES impacted inter-professional
care ?

Why?
Fees fever picture
32
How has FEES impacted inter-
professional care ?
• Results perceived as more “credible”
• Greater agreement with recommendations
• Better understanding of the swallowing
impairment
• Recognition for contributing towards access
and flow
• “You can do that today?!”
• Enhanced professional profile staff
empowerment

In Summary
• Fees proven to be a useful method of performing instrumental
assessments in in and outpatients across multiple patient
populations especially in Acute Stroke.
• FEES has been found to be an alternative to MBS and can be
utilized effectively in the acute care setting
• FEES may allow for early optimal assessment for stroke patients
with medical fragility, dependence on the ventilator, difficulty with
positioning, or fatigability
• Quicker instrumental assessment for stroke patients resulting in
earlier swallowing/nutrition plans and facilitating discharge to
most appropriate medical setting (e.g., rehab)
• The initiation of FEES has influenced MBS usage at LHSC
• The reduction of MBS usage has the potential to reduce costs for
the organization
