2Fall Risk Assessment Literature
- Morse Fall Scale
- Marianjoy Fall Risk Assessment
3Morse Fall Scale
- The Morse Fall Scale (MFS) is a rapid and simple
method of assessing a patients likelihood of
falling. - The MFS is used widely in acute care settings,
both in the hospital and long term care inpatient
settings. - It consists of six variables that are quick and
easy to score, and it has been shown to have
predictive validity and interrater reliability. - A large majority of nurses (82.9) rate the scale
as quick and easy to use, and - 54 estimated that it took less than 3 minutes to
rate a patient.
4Morse Fall Scale Indicators

- increase GI motility

- Age greater that 65 or less

Caution Club
7Guiding Question?
- Is the Marianjoy Fall Risk Assessment a valid
and reliable method for predicting rehabilitation
patient fall events if it is properly scored at
admission?
8Description of Research Study
- Pilot study of 50 patients
- 25 patients who had fallen
- 25 matched patients who had not fallen
- Dependent variable fall status
- Independent variables
- Caution Club status
- Admission FIM total score
- Modified admission Berg Balance total score
- Admission fall risk assessment
9Pilot Study Results
- Patients significantly differed on Berg, FIM, and
fall risk assessment scale - Five items found to separate fall groups
- History of falls
- Unilateral neglect
- Episodes of dizziness / seizures
- Special medications
- Diuretics and drugs that increase GI motility
- Sensory deficits

You never know whats in your grasp
11Replicated Study with a Larger Sample
- 2005 data used
- Total N 450 patients included
- 125 patients with documented fall status
- 325 patients who had not fallen were randomly
selected from dataset - 232 patients were on caution club status
- 218 patients not on caution club status
12Replicated Study with a Larger Sample
- Hypotheses tested
- Patients did not significantly differ on fall
status for - Fall assessment
- Admission FIM Score
- Modified Berg Balance Score
- Age
13Replicated Study with a Larger Sample
- Statistical Procedures
- Descriptive statistics
- Sensitivity and specificity on original scale
- Sensitivity and specificity on converted
dichotomous scale - Item analysis on dichotomous scale that separate
fallers from non-fallers - Total of 9 items discriminate groups
14Replicated Study with a Larger Sample
- Statistical Procedures
- Validity procedures using factor analysis
(component analysis) - Reliability analysis using Cronbachs Alpha
- Logistic regression to develop predictive model
of fall status - Development of new Caution Club threshold value
New Threshold Cut Score gt 4

Berg and FIM Significantly Differ, but Age does
not significantly differ
20Results from Item Analysis
- Nine items found to discriminate fall groups
- History of Falls (Weight 2)
- Impulsiveness (Weight 2)
- Communication Deficits
- Altered Elimination Patterns
- Unilateral Neglect
- Lower Extremity Hemiparesis
- Upper Extremity Hemiparesis
- Special Medications
- Diuretics and Drugs that Increase GI Mobility
21Factor Analysis and Reliability
- Three Components Extracted
- 55 Total Explained Variance in Model

Sensitivity a / (a c) 102 / 125 .82
Specificity d / (b d) 191 / 325 .59 False
Negative c / (a c) 23 / 125 .18 False
Positive b / (b d) 134 / 325 .41 PPV
a / (a b) 102 / 236 .43 NPV d / (c d)
191 / 214 .89
25Odds and Odds Ratio
- True Odds Ratio 6.25
- This can be interpreted to mean that a patient
who is on caution club status was 6.2 times more
likely to incur a fall than a patient who was not
on caution club status.
26Odds and Odds Ratio
- Relative Risk of a Fall 3.9
- This can be interpreted to mean that the risk of
patients on caution club status are 3.9 times
more likely to occur than those patients who were
not on caution club status.
