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?
Case study
Cohort study
Longitudinal study
Pre/post-study
Pre/post-study
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
,2
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
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?
Time-Series
Cross-Sectional
Pretest-posttest
Randomized Control Trial

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?
Time-Series
Cross-Sectional
Pretest-posttest
Randomized Control Trial
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
, 4
Using categorical variables with 0=no and 1=yes
Reporting the distribution of results or outcomes
What is a characteristic of qualitative research methods?
Utilizes large sample sizes
Determines causal relationships
Generalizes results to the population
Introduces subjectivity to data collection
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?
