QUESTIONS AND 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? -
correct 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? -
