D514 Actual Exam Questions with Correct
Answers
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?
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?
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.
Time-Series
Which type of data analysis could be used in quantitative research?
Reporting the distribution of results or outcomes
, What is a characteristic of qualitative research methods?
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?
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?
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?
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?
