1.
In conversations with her patients, a physical therapist notices that
patients who are on Workman's Compensation and have supportive
supervisors, eager for them to return to work, have more positive
outcomes in rehabilitation than those patients whose supervisors 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".
Question: What type of test could the therapist use to see if these two
factors have a measurable relationship?
Answer: Linear regression
2.
Data analysts at a large metropolitan hospital need to determine risk
factors associated with readmission within 30 days via the hospital's
emergency room among patients with COPD. The variables of interest
include age, gender, race/ethnicity, insurance status, and family support.
Question: Which statistical technique should be used?
,Answer: Regression analysis
3.
Several community health centers across a rural 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 therapists on a regular exercise program;
the third group will follow the diet and engage in the exercise.
Question: Which statistical test will be appropriate to use to determine
which treatment is most effective in controlling pre-diabetes?
Answer: ANOVA
4.
A hospital CFO is analyzing the cost benefits of using the patient
reminder system, which was implemented over a year ago, to see if the
automated system results in fewer missed appointments ("no-shows").
She is comparing quarterly reports from this past year on the volume of
patients who did not show up to their appointments to the volume of
patients from the previous year who did not show up to their
appointments, to see if the automated system has proven effective. She is
considering other variables as she reviews the data but is primarily
analyzing the number of "no-show" patients from last year's quarterly
reports to this year's.
,Question: Which statistical analysis should be used?
Answer: Time series analysis
5.
There are two standard treatments for children with 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 receive the cognitive behavioral
intervention and the other half will receive the dietary and biomedical
intervention.
Question: Which test is appropriate to determining the preferable
treatment?
Answer: Cross-sectional
6.
The vice president, CMO, and Operations Team collected data on
resources used by patients who have undergone coronary bypass and the
length of stays for a defined population of patients who received CABG
surgery. Since the raw data is complex to discuss and evaluate, the team
will use descriptive statistics to analyze the data to support their
decisions for recommendations.
, Question: Which of the following descriptive statistics could prove the
most useful?
Answer: The mean (average) length of stay and the mean number of
providers seeing each patient each day.
7.
Operates through the CDC; the National Health Care Surveys are
designed to answer key questions of interest to health care policymakers,
public health professionals, and researchers.
Answer: National Health Care Survey
8.
A healthcare organization is evaluating whether patient age, body mass
index (BMI), smoking history, and physical activity level can predict the
likelihood of developing hypertension. The outcome variable is whether
the patient has hypertension (yes/no).
Question: Which statistical analysis is most appropriate?
Answer: Logistic regression
9.
A chief nursing officer wants to compare the average patient satisfaction
scores among five medical-surgical units after implementing different
staffing models.
