care decisions and promoting quality of life through the prevention and
control of disease, injury, and disability
4. Agency for Healthcare Research and Quality (AHRQ) - ANSWER ✓ a part

founded by the United Nations (UN) and is the directing authority on
international health within the UN's system
,6. Statistical Package for Social Sciences (SPSS) - ANSWER ✓ a statistical
package that offers a variety of analytical and graphic software and is used
by many industries for its predictive analytics to help them make decisions
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".
7. What type of test could the therapist use to see if these two factors have a
measurable relationship? - ANSWER ✓ Linear regression
8. 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? - ANSWER ✓ Regression analysis
9. 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? - ANSWER ✓ ANOVA
10.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. - ANSWER ✓ time
series
11.Include "What are you predicting and why? How accurate is your prediction
and what actions are taken based on the prediction?" - ANSWER ✓
Modeling questions
12.Relies on mathematical algorithms to predict the probability of an outcome.
- ANSWER ✓ Predictive modeling
13.When used in the healthcare environment, it provides a ____________ score
(probability) for each patient or groups of patients, in order to determine,
inform, and influence organizational processes that pertain to large numbers
of individuals. - ANSWER ✓ Predictive analytics
14.Is a tool to plot the frequency and number of cases and is useful to identify
areas of high variance. - ANSWER ✓ Histogram
15.Normal ___________ visually reflects a well-formed bell curve. Variation
may appear to be skewed outside the normal distribution and require
additional testing for statistical significance. - ANSWER ✓ Distribution and
deviations
16.Reflects how close a sample mean is to the true population mean. This
calculation is essential for identifying variation that is a result of chance. -
ANSWER ✓ The standard error
17.Measures the distance along the x-axis of a normal distribution measured in
units of standard deviation. The ___________ is a unit that can simplify the
measurement of variation. - ANSWER ✓ The z-score
18.A quality improvement manager in Alaska is comparing data at her facility
on enrollment of patients using Medicaid and CHIP, from before the passage
of the Affordable Care Act to current data on Medicaid and CHIP
enrollment. - ANSWER ✓ Statistical modeling
19.The quality improvement team is reviewing quarterly incident reports and
evaluating the effect of Six Sigma strategies on the quantity of medication
, errors over the past two years. The team hypothesizes a continuous reduction
in medical errors for each quarter.
The sample consists of patient clinical and demographic characteristics.
Unfortunately, causation cannot be determined from the data available.
Which research method should be used to test the team's hypothesis? -
ANSWER ✓ time series
20.A hospital researcher has access to one year of hospital emergency
department claims data. The researcher is investigating the association of
race on the timeliness of delivery of care. The sample includes information
on patient demographics, insurance information, and emergency department
factors. Due to patient confidentiality, the sample does not include patient
clinical information and outcomes.
Which research method should be used? - ANSWER ✓ Cross Sectional
21.Which type of data analysis could be used in quantitative research? -
ANSWER ✓ Reporting the distribution of results or outcomes
22.What is a characteristic of qualitative research methods? - ANSWER ✓
Introduces subjectivity to data collection
23.Many physician practices now utilize an electronic health record (EHR)
system that includes a secure messaging feature. Some of these practices
have extended their contact with patients by conducting virtual visits
between people with diabetes and nurses who are certified diabetes
educators. The remote technology includes the ability to monitor blood
glucose data to determine if these values are within goal range. After six
months, the results of the blood glucose levels for the group participating in
the virtual visits were evaluated.
Which research method was used? - ANSWER ✓ Cross-sectional
24.A policy analyst is interested in determining if the prospective payment
system (PPS) has improved hospital efficiency over time during the past ten
years. The sample for analysis consists of ten years of data after the
introduction of the PPS and includes measures of efficiency and other
