For example, if the HR database groups employees by team, and team members are listed in order of seniority, there is a risk that your interval might skip over people in junior roles, resulting in a sample that is skewed towards senior employees. Interrupted time series must have at least 3 measurement points prior to and after the intervention is begun. What are exclusion criteria in research? Intervention must involve an RN or LPN functioning beyond the usual scope of practice, which must include adjustment of medications.
