Use of Soap and Water Versus Alcohol-Based Rubs to Prevent Nosocomial Infections
The study chosen for this topic researched the effects of waterless hand rubs versus the traditional hand scrubbing method to prevent infections in surgical rooms. One hundred operating room staff members from different medical centers were divided into two groups of fifty participants (Chen, Han, Kan, Chen & Hung, 2012). One group used waterless hand rubs and the other group of workers used traditional hand washing techniques as part of the scrubbing process for surgeries. The hands of the participants were scrubbed and a bacterial culture was done on the two groups of participants (Chen et al., 2012). After a forty-eight hour period of bacterial growth of both samples, the results demonstrated bacteria growth was equal among the two groups (Chen et al., 2012). There were no statistical significance found. The study concluded that alcohol-based rubs and water provide the same level of protection among operating room staff (Chen et al., 2012).
Strengths and Weaknesses
One of the strengths of the study was the method of conducting the study was the same among the two participant groups (Chen et al., 2012). The time the participants took in applying the alcohol-based rub and washing hands were the same. The weakness of the study was the participant sample was rather small (Chen et al., 2012). A larger study conducted at different facilities provides better evidence of the findings. Also, a study with a larger sample population may have also resulted in different findings (Chen et al., 2012).
Rationale for the Design
The study selected is a quantitative research that attempted to estimate the required scrubbing times using alcohol-based scrubs and traditional handwashing technique for operating room staff (Chen et al., 2012). Also the study focused on comparing the use of alcohol-based hand rubs versus the traditional handwashing techniques in prevention of nosocomial infections in the operating room (Chen et al., 2012).
Relationship Between Alcohol and Breast Cancer
The article reviewed focused on possible pathways of alcohol into the breast tissue and possible consequences. The study also reviewed the women’s age in relations to drinking habits, in an attempt to identify a possible connection between early alcohol consumption among women and breast cancer (Liu, Nguyen, & Colditz, 2015). The study concluded that moderate alcohol consumption is associated with higher risk of breast cancer (Liu, Nguyen, & Colditz, 2015).
Strengths and Weaknesses
A strength of the study is there was significant evidence to suggest that the risk of cancer increases by thirty-four percent for those women who had an alcohol intake greater than fifteen drinks per day (Liu, Nguyen, & Colditz, 2015). A weakness identified in the study was that other lifestyle components that may increase the risk of breast cancer were not taken into consideration when conducting the study (Liu, Nguyen, & Colditz, 2015).
