Using a theoretical framework from engineering sciences, the researcher believes that the physical set up of hospital rooms impacts rates of hand washing. After prolonged engagement, she observed the healthcare providers working on a medical/surgical floor of a hospital. As the result of her data analysis she purposefully selected 6 physicians, 10 nurses and 12 nursing aids to conducted in-depth interviews with. Subsequent to the analysis of that data she then purposefully selected 5 medical residents, 10 more nurses, the radiographers assigned to the portable imaging machine, and 15 patient transporters to conduct interviews with. She uses the data she collected and analyzed to develop a survey that she sent to 100 randomly selected hospitals across the northeast. What research design was used in this study? a.
