Analytical Methods of Healthcare Leaders - D5141. In conversations with her patients, a physical thera- Linear regression
pist notices that patients who are on Workman's Com-
pensation and have supportive supervisors, eager for
them to return to work, have more positive outcomes
in rehabilitation than those patients whose supervi-
sors have a negative attitude toward their employee's
injury: insisting they not return to work until they are
at 100% because if anything less they are "useless to
the job".
What type of test could the therapist use to see if
these two factors have a measurable relationship?
2. Data analysts at a large metropolitan hospital need to Regression analy-
determine risk factors associated with readmission sis
within 30 days via the hospital's emergency room

est include age, gender, race/ethnicity, insurance sta-
tus, and family support. Which statistical technique

3. Several community health centers across a rural ANOVA
state are gathering data on their pre-diabetic patients
and using A1c levels as a baseline measurement to
include patients in a research project. Three different
interventions will be applied.
One group of patients will receive a special diet to
follow; the second group will work with physical ther-
apists on a regular exercise program; the third group
will follow the diet and engage in the exercise.
Which statistical test will be appropriate to use to
determine which treatment is most effective in con-
trolling pre-diabetes?

sults in less missed appointments ("no-shows").
She is comparing quarterly reports from this past
year on volume of patients who did not show up to
their appointments, to the volume of patients of the
previous year, who did not show up to their appoint-
ments, to see if the automated system has proven
effective. She is considering other variables as she
reviews the data, but is primarily analyzing the num-
ber of "no-show" patients from last year's quarterly
reports to this year's.
5. There are two standard treatments for children with Cross-sectional
ADHD who display a specific set of characteristics.
One treatment is a cognitive behavioral intervention,
and the other is a dietary and biomedical intervention.
Both treatments have equally strong clinical evidence
supporting their efficacy. A researcher proposes a
comparison of the two interventions to determine
which is preferable. The children will be randomized
to one of two groups: half of the children will re-
ceive the cognitive behavioral intervention and the
other half of the children will receive the dietary and
biomedical intervention. Which test is appropriate to
determining the preferable treatment?
