Extract of sample "Alcohol Based Solution and Standard Handwashing"

Download file to see previous pages It concluded that hand-rubbing with liquid aqueous alcoholic solution could be safely used as an alternative to traditional hand-scrubbing in surgical practices.
2. The research done by Girou, et al. at 3 intensive care units in a university hospital in France, 12 healthcare workers were allocated to hand-rubbing with a waterless alcohol based solution and 11 were allocated to hand-washing with antiseptic soap. It concluded that the median percentage reduction in bacterial contamination with hand-rubbing was significantly higher than with hand-washing.
3. Research conducted by Karabay, et al. 35 nurses were randomly selected from a nursing staff of 141 and divided into 2 groups: hand rubbing and hand washing. Hand rubbing with alcohol-based solutions significantly reduced the bacterial contamination of the hands of the nurses more than hand washing with an antimicrobial soap. Compliance was also better in the hand rubbing group than in the hand washing group.
While framing our hypothesis we should consider the objective of our research. The purpose of this research is to compare hand-hygiene and skin condition after hand-rubbing with an alcohol based solution or washing our hands with an antiseptic soap. So, the primary object of our comparison would be 'hand-hygiene'. To measure hand-hygiene, we make a natural assumption that "Hands with lesser bacterial contamination are more hygienic". ...
So, the primary object of our comparison would be 'hand-hygiene'. To measure hand-hygiene, we make a natural assumption that "Hands with lesser bacterial contamination are more hygienic". Therefore we frame the following hypothesis as our 'Null Hypothesis'.
H0: The median percentage reduction in bacterial contamination using Alcohol Based Solution (ABS) is greater than that with hand-washing with liquid soap solution (LSS).
i.e. H0: MeABS > MeLSS
Our 'Null Hypothesis', in simpler words states that by using Alcohol Based Solutions we kill more bacteria on our hands and achieve disinfection better than liquid soap solutions. Our 'Null Hypothesis' thus assumes the objective of our research to be true. So, in a similar manner we can also state our 'Alternative Hypothesis' as:
Ha: The median percentage reduction in bacterial contamination using Alcohol Based Solution is less than or equal to that with hand-washing.
i.e. Ha: MeABS MeLSS
Step 2: To Formulate an Analysis Plan
For our analysis, we would be using the data obtained from three separate research projects carried out on similar topic.
1. Research conducted by Parienti, et al. at six surgical services from teaching and non-teaching hospitals in France, conducted between January 1, 2000 and May 1, 2001. In their research, "surgical services used two hand cleaning methods alternatively every month: a hand-rubbing protocol with 75% aqueous alcoholic solution and a hand-scrubbing protocol with antiseptic preparation." (Parienti et al, 2002) Thirty-day surgical site infection rates were the primary factor being monitored.
2. In the research done by Girou, et al. at 3 intensive care units in a university hospital in France in 2002, 23 nurses and nursing assistants had volunteered to participate. "12 ...Download file to see next pagesRead More

The Handwashing Techniques

Using the literature I will look at and explore the factors that may have influenced the learner and their performance in Scenario One (hand washing). I will then, with reference to the literature, identify one of these contributory factors and critically discuss and analyse the mentor's role in addressing the identified factor. I will then identify recommendations for best practice.

According to Rowntree (1987) "assessment occurs whenever one person in some kind of interaction, direct or indirect, with another is conscious of obtaining and interpreting information about the knowledge and understanding of the abilities and attitudes of this person".

..." failed "introduction of easily accessible dispensers with an alcohol-based waterless hand-washing antiseptic" succeeded in enhancing hand-washing rates among health care workers. (Bischoff 1017-1021). According to FDA definition alcohol contains active ingredients of 60% to 95% ethyl alcohol or 50% to 91.3% isopropyl alcohol in an aqueous solution by volume. Though one potential disadvantage of the use of alcohol in the operating room is its 'flammability', it is found that "aqueous 70% to 92% alcohol solutions have germicidal activity against bacteria, fungi, and viruses, but spores can be resistant."

Next, half the participants (three in number) were asked to disinfect their hands using only soap and water while the other half were asked to do so with the NHS standard handwash – alcohol and chlorhexidine in 1:10 dilution. Samples were taken of the fingers after disinfecting. Samples were sustained for 24 hours after which the bacteria counts were taken. It was found that for all participants, both for normal and NHS standard handwash, there was reduction in the bacteria counts post-disinfect over pre-disinfect but the normal handwash – only soap and water – porved more efficacious than the NHS standard one.

The Need of Handwashing

... (Tanner 2011). The subjects were asked to evaluate five popular products used for hand hygiene: alcohol foams, alcohol wipes, cloths impregnated with antiseptic solution, soapy water and portable sinks (Tanner 2011). Based on the results, it was found that alcohol foam was the most preferred hand hygiene product of patients. While it has been found by the study of Burton et al. (2010), as discussed previously, that washing with soap is the most effective way to decontaminate hands from bacteria, this information remains to be helpful. The patients are already aware of the purpose of hand washing but this awareness is not the sole factor for compliance. Even if a particular method is effective, it would remain useless if patients...

Critique of Technological Innovations, Activity Based Costing and Satisfaction Article by Davood Askarany

Many of the innovations have been introduced as early as 1980, such as “activity-based costing (ABC); activity management (AM) and activity-based management (ABM); local information system (LS); balanced scorecard (BS); life cycle costing (LCC) and target costing (TC) [and] strategic management accounting (SMA).” (Askarany, Smith and Yazdifar 54). However, few of these have been implemented and utilized to their full potential. The authors propose to find a reason for this.

ABC focuses on costs associated with activities, but also evaluates whether those activities add value, thus providing a means of understanding how to most effectively reduce costs. In addition to cost reduction benefits, applying ABC giv...

Alternative Dispute Resolution Based on the English Legal System

These common-law courts were the competitors of the usual manorial courts in providing justice in a faster and more inexpensive manner.
