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?
|\ |\ |\ |\ |\

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?
|\ |\ |\ |\ |\

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?
|\ |\ |\ |\ |\

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? |\ |\ |\ |\
