What type of study is described in the following excerpt? An interprofessional team wants to test a new intervention to see whether it will improve central-line associated bloodstream infection (CLABSI) rates.

Data was collected and analyzed using the Statistical Package for the Social Sciences (SPSS). Descriptive statistics were used to report the data.

Nurses were asked to complete the survey. Upon completion of the survey, nurses were invited to participate in video conference focus groups and one-on-one interviews with a research assistant by video conferencing. Survey results were reported using descriptive statistics, and themes were identified and reported from the data collected in the focus groups and one-on-one interviews.
