WGU D514 FINAL EXAM ON ANALYTICAL METHODS OF
HEALTH LEADERS STUDY THIS!!
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?
Answers 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?
Answers 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?
Answers Time-Series
Which type of data analysis could be used in quantitative research?
Reporting the gender of participants
Ranking the severity order with 1 as the worst and 4 as the best
Reporting the distribution of results or outcomes
,Using categorical variables with 0=no and 1=yes
Answers Reporting the distribution of results or outcomes
What is a characteristic of qualitative research methods?
Answers Introduces subjectivity to data collection
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?
Answers Cross-sectional
A researcher wants to determine whether continuity of care is improved with the
use of coordination of care documents among primary care physicians and
specialists. The researcher decides to review various published studies to assess the
clinical effectiveness of these documents on patient outcomes.Which research
method is being used?
Answers Meta-analysis
The state public health researcher wants to begin a five-year initiative to coordinate
immunizations for children in the foster care system. The results will be compared
to previous years to measure the effectiveness of the initiative.Which research
method should be used to study this initiative?
Answers 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?
Answers 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?
Answers 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 MethodsA 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?
Answers Research design
Assoc. between pt satisfaction & hospital market share. Researcher hypothesizes
that increased pt satisfaction will lead to increase in hosp. market share.
Longitudinal study of 7 years will be conducted to assess the change in hospital
market share over time. Urban hospitals from the U.S. that have > 100 beds will be
included. The data set will include hosp. characteristics and market characteristics.
Admin. data will be obtained from the Am. Hospital Association's Annual Survey
of Hospitals, the Area Health Resources File, and the Hosp. Compare website. The
