A nutritionist is assessing the impact of patient education on dietary behavior. The
treatment involves having a group attend a cooking class. They will then be
assessed on the likelihood of using the cooking information learned.Which data
source should the nutritionist use?

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?

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?

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?

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
