WGU C985 EXAM QUESTIONS WITH
COMPLETE SOLUTIONS
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
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 relevant control variables. The analyst
hypothesizes that hospital efficiency should have increased each year after the PPS
was implemented.
Which research method should the analyst use? - ANSWER-Time Series
A researcher wants to determine whether continuity of care is improved with the use
Which research method should be used to study this initiative? - ANSWER-Pre/post-
study
Using publicly reported data from Centers for Medicare & Medicaid Services,
researchers want to examine the relationship between 30-day readmissions and
mortality rates for patients with heart failure at five facilities. Before this can be done,
researchers need to estimate mortality rates and readmission rates from heart
failure.
Which statistical technique should be used to calculate the estimated rates? -
ANSWER-Regression analysis
Researchers want to determine if a particular risk factor or risk factors are associated
with the frequency for nonelective readmission within 30 days among patients with
diabetes in a metropolitan area. The variables of interest include age, gender,
race/ethnicity, and insurance status.
Which statistical technique should be used? - ANSWER-Regression analysis
A hospital researcher is interested in investigating the association between hospital
ownership (i.e., government, investor, and not-for-profit) on overall hospital quality
scores.
Research Methods
, A cross-sectional data set of all urban hospitals from eight states is used in this
study. The data were obtained from various administrative databases: Medicare
Hospital Cost Report Information System, the American Hospital Association, and
the Area Health Resource File. Descriptive statistics are used to summarize the
data. An ordinary least squares regression is used to test the relationship between
ownership status and hospital quality while controlling for hospital and market
characteristics.
Which component is missing from these research methods? - ANSWER-Research
design
A hospital researcher is interested in the association between patient satisfaction
and hospital market share. The researcher hypothesizes that increased patient
satisfaction will lead to an increase in hospital market share.
Research Methods
A longitudinal study of seven years will be conducted to assess the change in
hospital market share over time. Urban hospitals from the United States that have
more than 100 beds will be included in the analysis. The data set will include hospital
characteristics and market characteristics. Administrative data will be obtained from
the American Hospital Association's Annual Survey of Hospitals, the Area Health
Resources File, and the Hospital Compare website. The variables included in the
data set will control for other factors that may impact hospital patient satisfaction.
Statistical significance will be set at α = 0.05 for the analysis. The results of the
analysis will be - ANSWER-Analysis plan
dividing members into "like" subgroups before performing research - ANSWER-
Stratification Analysis
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
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
