$1.$ A study was conducted by an HIM researcher to evaluate reimbursement outcomes after using computer$-$assisted coding. Data on the level of reimbursement as a measurable outcome of using such technology were collected. The researcher also conducted focus groups to analyze questions on how or why this particular technology did not achieve the expected outcomes. What type of research approach is the HIM researcher using in this study? Explain your rationale.

$2.$ What type of research approach is used when a researcher analyzes data by using electronic display boards in hospital departments to monitor the number of patients with a list of fall risk factors within $24$ hours of admission? Explain your rationale.

$3.$ The HIM director is evaluating the privacy and security features of two E H R systems as a part of the purchasing decision for the organization. What is the key driving factor as the HIM director plans this research?

$4.$ A researcher intends to assess the amount of time physicians spend documenting in the E H R and identify a better workflow in practice. What type of research questions would likely be used by the researcher? Give an example.

$5.$ Compare correlational study design with evaluation study design. Recommend which one of these designs is most appropriate for a study to investigate the association between the use of EHRs and physician burnout.

$6.$ A researcher read a study entitled $$EHR use continues to contribute to physician burnout.$$ This study used a new questionnaire to ask physicians about their use of EHR over the years. The researcher decided to examine the strength of this new questionnaire. How does the researcher assess whether the new questionnaire is valid and reliable?
