Lab Report #1: Hand washing ---- is it worth it?
Introduction:
This experiment illustrates the importance of handwashing and proves that hand washing is worth it. Since our hands are constantly coming into contact with ourselves and others, touching surfaces, grabbing objects, being sneezed into, etc., keeping our hands clean is one of the most effective, yet simple way we can take to avoid getting sick and spreading germs to others. Many diseases and conditions are spread by not washing hands with soap and clean, running warm water. “The human skin is a host to anywhere between 10,000-10,000,000 bacteria per square centimeter and since health care providers come into contact with pathogenic bacteria by being engaged in patient care, hand washing can reduce the risk of spreading diseases (page 3).” The objective of the experiment is to test the effectiveness of hand washing and demonstrate normal flora. This report presents the procedures and materials for the experiment, the experiment's results, and an analysis of those results.
Exercise #1
Materials Needed:
A Nutrient Agar Petri Plate
Sharpie Marker
Fingers and/or Thumb filled with bacteria
Sink
Soap
Paper Towels
Incubator rack marked 37C
Procedures:
In the beginning of lab, we were advised to obtain a nutrient agar petri plate, which is used for the cultivation of microbes supporting growth of non-fastidious organisms. Since it contains many nutrients, a wide variety of bacteria and fungi can grow. Taking the plate,
Thoroughly washing your hands can be one of the best ways to prevent the spread of pathogens that cause illnesses. Our bodies have several lines of defense to fight infections. It is very important to do what we can do to avoid the pathogens from entering our system in the first place. Our hands pick up microscopic pathogens from objects that were touched by people who may not have washed their hands very well. When we forget to wash our hands or don’t wash them properly, we can spread pathogens from our hands to our internal systems by touching other parts of our body. During this lab activity, my partner and I will test the effectiveness of different hand-washing times, techniques, and
Three paper towels A, B, and C where tested on absorbency. This experiment was tested twice. Paper towel A was 26.5 by 28 centimeters. Paper towel B was 26.5 by 28 centimeters. Paper towel C was 15 by 28 centimeters. Scissors were obtained and each paper towel was cut to 13.5 by 15 centimeters. The weight of the three paper towels at this size was 0.9 grams dry for paper towel A, paper towel B weighed 0.8 grams dry, and paper towel C weighed 1.2 grams. Three beakers weighing 12.2 grams each were obtained. Each beaker was filled with 100ml of water with the outcome of them weighing 128.1 grams each. The weight of each paper towel dry was deducted from the weight of each paper towel. Paper towel A was left to soak for seven seconds.
Hospital acquired infections (HAIs) affect over 1.7 million patients each year, causing almost 100,000 deaths annually in the United States alone (Johnson, 2010). According to the World Health Organization, HAIs are the most frequent adverse event in the healthcare industry. Fortunately, most of these infections can be prevented with one single intervention, proper hand hygiene (“The Evidence,” n.d.). Four out of five pathogens that cause illness are spread by direct contact. Proper hand hygiene eliminates these pathogens and helps to prevent cross-contamination and HAIs (Linton, 2015; “Hand Hygiene,” n.d.). Reduction of cross-contamination and HAIs improves patient outcomes, increases employee wellness, and lowers health care costs. Adherence to proper hand hygiene is the single most important safety measure in the health care setting. However, for many years compliance to proper hand hygiene in the healthcare industry has been dismally low. New and inventive measures must be implemented to increase compliance to proper hand hygiene and lower the rate of hospital-acquired infections.
Keeping our hands clean is one of the most effcient and important steps we can do as humans to avoid getting sick or spreading germs to other people. Unwashed hands spread many diseases such as the flue, E. coli, and salmonella. Unfortunately, hand hygiene is still one of today’s most leading causes of infection in health care facilities. The risk of clinicians, patients, and visitors not complying with hand hygiene protocols creates a practice problem for nurses and their patient care. The cause of health care infections, also known as, health care-associated infections (HAIs) are increasing along with the rise of the inability to control or treat infections that are multi-drug resistant. Lack of proper hand hygiene is a major problem in clinical settings sourcing from critical care divisions where the most contaminations are prevalent. This paper will discuss how hand hygiene affects the nursing process and solutions of how to better prevent HAIs within the nursing scope of practice.
This study was intended to prove that hand hygiene practiced according to the CDC guidelines will decrease the incidence of hospital acquired infections. This could not really be proved in this study since the hospitals were not able to maintain improvement in hand hygiene. Health care workers were familiar with guidelines but significant practice changes were not maintained. Some of the infection rates did improve during this time but the correlation with hand hygiene is not consistent. There were other practice changes occurring during this same time and those changes may be responsible for the decreased infection rates.
CDCs clean hands count campaign aim to improve healthcare provide adherence to hand hygiene recommendations, address, myths and misperceptions about hand hygiene and empower patients to play a role in their care by asking or reminding healthcare providers to clean their hands and the most germs that cause serious infections in healthcare are spread by people’s action, every patient is at risk of getting an infection while they are being treated for something else, hand hygiene is a great way to prevent infections and healthcare providers clean their hands less than half of the time they should, good hand washing is the first line of defense against the spread of many illness.
Generations of people have considered handwashing a measure of personal hygiene. In 1847, Dr. Semmelweis insisted that healthcare providers wash their hands with disinfecting agents between patients. This early hand hygiene practice resulted in a decrease in mortality rates among hospital patients (CDC, 2002). The CDC’s Healthcare Infection Control Practices Advisory Committee published the Guideline for Hand Hygiene in Health-Care Settings in 2002 that is based on hand hygiene foundations developed in generation past. In 2014, this guideline is still available online and used as a reference
The purpose of this study is to evaluate the impact of hand hygiene and how it decreases the transmission of infection throughout (Bloomfield, Aiello, Cookson, O'Boyle, & Larson, 2007). Handwashing can include alcohol based hygiene items and handwashing with soap and water. This study main focus was on North American and Europe. There is plenty of supporting rationale to backup why this study was conducted. Some of the few things this study wanted to achieve are hand hygiene is key to staying healthy and reducing infection. This needs to be followed both in the workplace and around the community to abstain from infections. Handwashing can be achieved by soap and water or hand sanitizers that removes or eliminates many microorganisms on the surface of the hand (de Oliveira Dourado, da Costa Barros, Diogo de Vasconcelos, & da Silva Santos, 2017). This can impact many individuals by using this technique to keep foreign germs off of the hands. The importance of washing hands

Good hand hygiene is the simplest, yet proven strategy to counteract hospital infection. However, the difficulties of achieving good levels of compliance are well noted in the literature. There are several seeming barriers to carry out adequate hand hygiene:
Another purpose of this experiment is to stress the importance of knowing the identity of a microorganism. Knowing the species of microorganism present in a sample provides a
Infectious diseases that are commonly spread through hand to hand contact include the common cold, and several gastrointestinal disorders such as diarrhoea (WaterAid, 2006). Human hands usually harbour microorganisms both as part of a person’snormal microbial flora as well as transient microbes acquired from the environment (Lindberg et al, 2004).
This assignment will encompass how the results of the personal hygiene and susceptibility microbiology experiments provide a framework for the basis of the NICE Clinical Guidance (CG139) on Infection and how crucial the reasons for the hand wash protocol and hygiene is in all healthcare settings.
