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
Cross-Sectional
Pretest-posttest
Randomized Control Trial - 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?

Pretest-posttest
Randomized Control Trial - 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?

Randomized Control Trial - Answer-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

Using categorical variables with 0=no and 1=yes - Answer-
Reporting the distribution of results or outcomes
What is a characteristic of qualitative research methods?
Utilizes large sample sizes
Determines causal relationships

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
, 4|Page
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?
Time-series
Clinical trial
Pretest-posttest
Cross-sectional - Answer-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?
Case study
Cohort study
Meta-analysis
