In conversations with her patients, a physical therapist notices that patients who are on Workman's
Compensation and have supportive supervisors, ea-ger 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✔✔ correct answ
Linear regression
1. 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 tech-nique should be used✔✔ correct
answ Regression analysis
2. 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✔✔ correct answ ANOVA
3. 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 variablesas she reviews the data, but is primarily analyzing the number of
"no-show" patients from last year's quarterly reports to this year's.: time series
4. 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✔✔ correct answ Cross-sectional
5. 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✔✔ correct answ The mean (average) length of stay and
The mean number of providers seeing each patient each day
6. 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.: National Healthcare Survey
7. Operates through the CDC: data on birth, death, marriages, divorces, and fetal deaths.: National Center for Health Statistics
(NCHS)
8. Incidence and prevalence of diseases, survival statistics, high-risk popula-tions, trends over time. Data
gathered from medical records, surveys, inter-views. NCHS has responsibility for these databases.: Public Health
Databases
9. 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.-
: National Practitioner Data Bank (NPDB)
10. Acute care and skilled nursing facility claims data. Demographics on pa-tient, 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.: Medicare Provider Analysis and Review (MEDPAR)
11. Medical screening and medical are two fundamental strate-gies for
optimizing employee health. Medical screening is only one compo-nent of a comprehensive medical program.
The fundamental purpose of screening is early diagnosis and treatment of the individual and thus has a clinical
focus.: Surveillance records
12. 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.: National Center for Health
Statistics (NCHS)
13. Is a set of large-scale surveys of families and individuals, their medical providers, and employers across the United
States.: The Medical Expenditure Panel Survey (MEPS)
14. Data mined from billing/ coding departments, many organizations use software or services to facilitate their
process.: Health Payment Systems Data
15. 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.: HealthResources and Services Administration (HRSA)
16. Financial health is critical to any organization. Managing financial data en-sures adequate resources for long
and short term goals, and sound financial planning✔✔ correct answ Accounts Receivable and cost data
17. Catheter associated urinary tract infection is an infection involving any part of the urinary system, including
urethra, bladder, ureters, and kidney: CAUTI
18. Medical complications due to infection impact patient recovery, often re-sulting in thousands of dollars
in additional cost; data also beneficial for improvement in infection control processes✔✔ correct answ Post-op
infection rate
19. Central Line Associated Blood Stream Infection: CLABSI
20. Hospital Consumer Assessment of Healthcare Providers and Systems: HCAH-PS
21. The Affordable Care Act (ACA) added a section to the Social Security Act establishing the Hospital Program.
It requires CMS to reduce payments to hospitals with excessive . This was implemented back in 2012.-
