WGU C985 HEALTH CARE ANALYTICS UPDATED
ACTUAL QUESTIONS AND CORRECT ANSWERS
Question:
1. Linear regression
Answer:
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".
What type of test could the therapist use to see if these two factors have a measurable relationship?
Question:
2. Regression analysis
Answer:
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. Which statistical technique should
be used?
Question:
3. ANOVA
Answer:
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.
Which statistical test will be appropriate to use to determine which treatment is most effective in
controlling pre-diabetes?
Question:
4. time series
Answer:
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 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
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:
5. Cross-sectional
,Answer:
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
of the children will receive the dietary and biomedical intervention. Which test is appropriate to
determining the preferable treatment?
Question:
6. The mean (average) length of stay and
The mean number of providers seeing each patient each day
Answer:
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. Which of the following
descriptive statistics could prove the most useful?
Question:
7. National Healthcare Survey
Answer:
Operates through CDC; the National Health Care Surveys are designed to answer key questions of interest
to health care policy makers, public health professionals, and researchers.
Question:
8. National Center for Health Statistics (NCHS)
Answer:
Operates through the CDC: data on birth, death, marriages, divorces, and fetal deaths.
Question:
9. Public Health Databases
Answer:
Incidence and prevalence of diseases, survival statistics, high-risk populations, trends over time. Data
gathered from medical records, surveys, interviews. NCHS has responsibility for these databases.
Question:
10. National Practitioner Data Bank (NPDB)
Answer:
This database is queried as part of the physician credentialing process when applying for medical staff
privileges and every two years afterward. It contains data on medical malpractice, adverse licensure
actions, suspensions, certain professional review actions, such as denial of medical staff privileges.
Question:
11. Medicare Provider Analysis and Review (MEDPAR)
, Answer:
Acute care and skilled nursing facility claims data. Demographics on patient, information on provider, on
Medicare coverage for the claim, total charges, charges broken down, codes and diagnostic related group
(DRG) data. Only contains data on Medicare patients.
Question:
12. Surveillance records
Answer:
Medical screening and medical _______________ are two fundamental strategies for optimizing employee
health. Medical screening is only one component of a comprehensive medical _____________ program.
The fundamental purpose of screening is early diagnosis and treatment of the individual and thus has a
clinical focus.
Question:
13. National Center for Health Statistics (NCHS)
Answer:
A part of the U.S. Department of Health and Human Services, is the nation's medical research agency —
making important discoveries that improve health and save lives.
Question:
14. The Medical Expenditure Panel Survey (MEPS)
Answer:
Is a set of large-scale surveys of families and individuals, their medical providers, and employers across
the United States.
Question:
15. Health Payment Systems Data
Answer:
Data mined from billing/ coding departments, many organizations use software or services to facilitate
their process.
Question:
16. Health Resources and Services Administration (HRSA)
Answer:
Is an agency of the U.S. Department of Health and Human Services. It is the primary Federal agency for
improving health care to people who are geographically isolated, or economically or medically vulnerable.
Question:
17. Accounts Receivable and cost data
Answer:
Financial health is critical to any organization. Managing financial data ensures adequate resources for
long and short term goals, and sound financial planning.
Question:
18. CAUTI
