WGU C985 EXAM QUESTIONS WITH
COMPLETE SOLUTIONS
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
Which type of data analysis could be used in quantitative research? - ANSWER-
Reporting the distribution of results or outcomes
What is a characteristic of qualitative research methods? - ANSWER-Introduces
subjectivity to data collection
A large urban hospital has implemented a new patient registration system to reduce
patient complaints, streamline the process, and make it easier to understand.
The hospital had been monitoring patient wait times for registration prior to
implementing this change.
Which aspect of wait time was analyzed in the application of descriptive statistics
applied for this scenario? - ANSWER-An average of wait times was analyzed.
A surgical center is experiencing patient attrition. The center has received bad
reviews online. One area of complaints is that the center is dirty in common areas.
The center conducted a survey to ascertain what the major complaints were. The
center has decided to outsource its maintenance in an effort to improve patient
satisfaction scores.
The median patient satisfaction scores were determined from the survey.
How were descriptive statistics applied in this scenario? - ANSWER-To determine
the 50th percentile of patient satisfaction scores
An administrator at an established hospital decided to create a new data collection
plan for the quality improvement initiative because the former plan was not
acceptable.
