Is the use of soap and water or alcohol-based-rubs more effective in preventing nosocomial infections?

Is the use of soap and water or alcohol-based-rubs more effective in preventing nosocomial infections?

The type of research design for this question would be quantitative as it is using numerical objective data that deduces the effects of either the use of soap and water versus an alcohol-based-rub; utilizing causality in which it gives a cause and effect (Grave, Grove, & Sutherland, 2017, pp. 192-194).  “Quantitative research may be interventional or nonintervention…. Interventional designs test the effect of an intentional action, called an intervention, on a measured result” (Grave, Grove, & Sutherland, 2017, p. 192). Therefore, this theory would be interventional as it explores specifically the effects of using soap/water against the use of an alcohol-based-rub.

This design was chosen as it specifically meets the criteria to be classified as quantitative methodology utilizing interventional design.  In a specific clinical trial by Clinicaltrials.gov it identifies the design as interventional regarding the investigation of efficacy of water/soap and alcohol-based-rub for surgical hand preparation (2012).
