and evaluating the effect of Six
Sigma strategies on the quantity of

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?

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

A policy analyst is interested in Time-Series
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?

What is a characteristic of qualitative Introduces subjectivity to data collection
research methods?
Utilizes large sample sizes
Determines causal relationships
Generalizes results to the population
Introduces subjectivity to data
collection
Many physician practices now utilize Cross-sectional
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
