Ten pathogens of interest that are commonly causative agent in drinking water disease were identified to be included in the cost-benefit analysis: Campylobacter sp., Salmonella sp., E. coli O157:H7, Adenovirus, Rotavirus, Hepatitis A, Cryptosporidium sp., Giardia sp., Norovirus, and Legionella. Infection rates, incident cases, acute gastrointestinal (AGI) cost per case, sequelae rates and cost per case, and mortality rates and cost per case were identified for each of the ten identified pathogens. When data was unavailable, an estimate was made based on relevant data identified in the literature. Those values were then used to calculate the annual costs associated with AGI illness cases and the number of cases and total annual costs …show more content…
As such, this approach assumes all microbial removal is due to an RO system. This approach also assumes that a POU device will be used in every household in the United States (325,310,000 population), each household averages 2.58 individuals (U.S. Census 2010), and annual reverse osmosis POU treatment cost equal to $136 ($680 per 5 years [$300 initial cost and $95 per year after the first year]) per household per year ($52.71 per person) for a national household intervention cost of $17.1B, annually. Equation 1 $USD per averted case=|(〖Cost〗_i-〖Cost〗_n)/(〖Cases〗_i-〖Cases〗_n )| In Equation 1, Costn equals no intervention, Costi equals POU intervention, Casei equals the number of cases without a POU device intervention, and Casesn equals the number of estimated cases expected using a POU device intervention. In this case, the POU intervention is a RO system which includes pre-filtration and activated carbon filtration. The sum value of an RO system ($680/5 year) was divided by 5 years to form an annual POU intervention cost of $136. Other POU devices are approved for the treatment of microorganisms (e.g. UV systems). However, the current study utilized information from the epidemiological study undertaken by Payment et al. (1991) who examined the effects of an intervention (RO system with
In addition, the research has also relied on the laboratory data to complete this research (Garner, Jarvis, Emori, Horan, Hughes, 1998). Information given in the article, Infection surveillance in home care: device-related incidence rates were also used by the researchers to accomplish the research.
A total of 5,432 blood cultures were obtained from 2,642 patients and a significantly lower rate of contamination were seen in those specimens obtained by a dedicated phlebotomist. The phlebotomist collected cultures had a contamination rate of 2.4-3.6%, with an overall rate of 3.1% and the non-phlebotomy collected cultures showed contamination rates 6.2-10.2%, with an overall rate of 7.4% (Gander et al., 2009). The difference in the median patient charges between the negative ($18,752) and false-positive cultures ($27,472) resulted in additional charges totaling $8,720 for each contaminated event (Gander et al., 2009). The median increase for length of stay only increased from 4 days (negative culture) to 5 days (false-positive culture); whereas, patient’s with significant bacteremia had an additional median charge of $32,303 and 8-day median length of stay (Gander et al., 2009). This study goes on to state that with the estimated $8,720 for each episode of a contaminated blood culture, the prevention of only five contaminated blood cultures a year might fund the yearly salary for one dedicated phlebotomist in the ED and could potentially save the hospital $4.1 million in excess charges annually (Gander et al., 2009). This literature precisely defines reasonable need for correct collection of blood cultures in the emergency setting and provides evidence for former PICOT question.
Clean water is essential to our basic needs as human beings and has been acknowledged as a basic human right according to the UN as of July 28, 2010. Still, 1 in 9 (782 million) people don’t have access to clean water, 1 in 3 (2.5 billion) don’t have access to adequate sanitation which results in the spread of often fatal and preventable disease. In a world where 2 in 5 people own a smartphone, it’s easy to forget that for some people even the most basic necessities are hard to come by. Approximately 3.5 million people die every year due to inadequate water supplies. Access to sanitation and safe drinking water could save the lives of 1.5 million children each year.
If you are a parent who wants to help keep your child's teeth healthy, then you likely know that they need to get enough fluoride. While fluoride toothpastes provide your child's teeth with some fluoride, systemic fluoride is also important, as it is doesn't just coat teeth, but instead keeps teeth healthy from the inside out. Most children's main source of systemic fluoride is the water they drink. However, you may not know how systemic fluoride is enough, and even how much your child is getting. Here is a guide to finding out how much fluoride from tap water your child is getting and how much is enough.
It was concluded that out of the 44 wells pipetted, 13 were magenta meaning they were positive for Coliforms. After placing both the 50ml tube and well plate under the ultra violet light, it was found that only one well plate was positive for Escherichia coli despite the fact that the 50ml sample mixed with the COLISURE packet was negative for Escherichia coli. The calculation for the total volume dispensed in the wells was calculated and was 0.2ml x 44 wells = 8.8ml. Then, the information gathered about the number of wells positive and negative for Escherichia coli was then plugged into the equation that will result in the number of cells per 8.8ml for both wells positive for Coliform and for wells positive with Escherichia coli. Using the calculation (1/V) x ln(total # of wells/# of negative wells) it was concluded that there were 1.75 cells per 8.8ml in the positive Coliform wells and 15.4 cells per 8.8ml in the one well positive for Escherichia coli. To find these answers the following equation was used for both Coliforms and Escherichia coli: (1/.2) x ln(44/31)= 1.75 Coliform cells per 8.8ml of sample, and (1/.2) x ln(44/43)= 15.4 cells of Escherichia coli per 8.8ml of
All around the world, countries are fighting to keep their drinking water clean. Whether it’s streams, rivers, or lakes, countries have taken great measures to maintain high quality drinking water for both human consumption and animal consumption. Countries must first understand the sources of the polltion, then determine the best methods to eliminate the pollution. Clean drinking water is a valuable resource and a the key to human survival. Plants and animals also depend on water for their growth, so all water must be kept clean. The major contributors to water pollution can be classified in three categories, industrial, agricultural and municipal.
The disease, cholera, is an infection of the intestines, caused by the bacterium Vibrio cholerae. As stated in Microbes and Infections of the Gut, the bacterium is “a Gram-negative, comma- shaped, highly motile organism with a single terminal flagellum” (105). Cholera is characterized by the most significant symptom that presents with the disease, diarrhea, and victims can lose up to twenty liters of body fluids in a day. Cholera can be a serious disease, due to the serious dehydration that can occur, but it is only fatal if treatment is not administered as soon as possible. This research paper includes information on the causes of cholera, symptoms, ways of treatment, studies of treatments, complications that may occur, the
How many of you, when you go to a restaurant and the waiter/waitress asks you what you want to drink ask for water?
Water is a very important commodity to live. Some people say it’s a right, but others at as if it’s a privilege, and as a result, people lack it. The human body is about sixty percent water, but in what I have seen just in my twenty years of life, people do not drink merely enough of it. Instead, water has been replaced as a go-to drink by things like milk, coffee, pop, or energy drinks, but natural energy lies in water. With water we can be more energized, awake, and of course, hydrated, which all together collaborate to help us flourish, stay healthy, and live long. It’s most of the earth’s surface, too; water’s all around us, but we neglect it and deny its crucial place in our health and humanity.
“Drinking water is like washing out your insides. The water will cleanse the system, fill you up, decrease your caloric load and improve the function of all your tissues.” – Kevin R. Stone --
The Flint Water Crisis is a current health and safety issue that is affecting thousands of Americans in Flint, Michigan. Residents of Flint are unable to use and trust the water from their taps due to high levels of contamination and lead exposure. Children and adults have both suffered from exposure to this water supply. Rashes and illness have been common across the city. The water crisis in Flint developed its start when the city stopped receiving their drinking water from Lake Huron and started tapping into the Flint river. Because of the many cost cutting measures, this change has lead to numerous environmental, economic, social, legal, ethical, and risk management concerns over how the Flint government handled this issue.
Drinking water is a necessary activity for human’s life. The aim of this research was to identify habits of international students with the hypothesis was the drinking water habits of overseas students change when they come to Australia. In order to recognize the drinking water habits of international students, the questionnaire
As the worlds population grows, it is forced by circumstances that it has created to face the limitations of the worlds resources. Most people in the US have always been fortunate enough to have enough of whatever they wanted. When something they like breaks or wears out, they throw it away or buy a new one, and they often don’t even make an attempt to repair an item. They neglect basic maintenance until they damage their belongings beyond repair, and expect that they’ll always have enough. But some things are beyond their control, beyond there power or financial ability to replace or repair. The world’s drinking water supply is one of these without concern, without attention, without preventative maintenance and reclamation and
Every day Americans depend on public water systems to treat and deliver over 44 billion gallons of water to homes daily (“Importance of Clean Water”). However, Americans
