Applications of Epidemiology – A Case Study

Assignment 1: Applications of Epidemiology – A Case Study

Worth 280 points

The situation at Good Health Hospital has become a bit overwhelming ever since the outbreak of E. coli in Ward 10 on the second floor. It appears that there are six (6) cases of the disease. To better understand the situation, communication with the CDC has revealed that this particular bacterium can be found in many everyday items. The CDC recommends that investigation begins in the hospital kitchens, since E. coli can be transmitted via contaminated vegetables, as well as delicatessen meats such as salami and other cold cuts. The following table shows the number of cases identified so far:
Case Age Gender
1 23 M
2 21 F
3 15 M
4 42 F

After meeting yesterday with chief administrator Joe Wellborn, it has been decided that the litigation issues with one (1) of the patients may need further information to determine if the patient was already symptomatic with the bacteria prior to admission.

Research has indicated that hospitals operating in the Tampa Bay area have been known to have cases of E. coli contamination. This substantiates the need for further investigations by the County Health Department.

Due to the severity of the cases, and the potential for further spread, it is recommended that the hospital seek alternate vending services since the present suppliers cannot verify sanitation protocols for their products.

In conclusion, the study done at Good Health Hospital has indicated that the E. coli outbreak was in fact caused by spoil food from the cafeteria.

As a social science researcher working for a regional hospital, you are placed in charge of contacting the DOH from your home state, as well as the CDC for statistical data on nosocomial diseases that frequently cause illness at your health care facility. Using information from both agencies, evaluate the data on common nosocomial diseases and compile a treatment contingency plan for dealing with the hospital infections.

Write a five to six (5-6) page evaluation report in which you:

Analyze Good Health Hospital’s records and itemize recent nosocomial infections that occurred within the past year. In your report, categorize the different parameters (i.e., person, time, place, ethnicity, and gender) used in the compilation of data into the information summative.
Propose at least six (6) questions for the health care administrator at Good Health Hospital, regarding potential litigation issues with infections from the nosocomial diseases. Rationalize, in your report, the logic behind your six (6) questions.
Identify a targeted audience within Good Health Hospital, and prepare an implementation plan based on your hypothetical meeting with the hospital health care administrator. Propose four (4) steps that will be useful in the final implementation plan.
Suggest at least five (5) recommendations to your department head based on the steps taken in the implementation plan. Provide rationale for your suggestions.
Using these approved recommendations, design a safety protocol itinerary that must be placed in public access areas of the hospital.
Use at least four (5) PEER_REVIEWED academic resources in this assignment. These must come from journal sources. Note: Fact Sheets, Wikipedia, and non-academic Websites do not qualify as academic resources.

Your assignment must follow these formatting requirements:

Be typed, double spaced, using Times New Roman font (size 12), with one-inch margins on all sides; citations and references must follow APA or school-specific format. Check with your professor for any additional instructions.
Include a cover page containing the title of the assignment, the student’s name, the professor’s name, the course title, and the date. The cover page and the reference page are not included in the required assignment page length

Introduction

            Escherichia coli (E. coli) is a bacteria found in the intestine of health animals and people, but a time it causes havoc to the public if ferocious strain such as E. coli O15:H7 gain the entry into the intestinal track. This strain causes vomiting, bloody diarrhea and abdominal cramps thus raising concern in the public health(Schneider, 2009). Nonetheless, there several strains of E. coli which are harmless and causes mild diarrhea. Studies have shown that people get exposed to E. coli through undercooked ground meat, raw vegetables and contaminated food and drinks. Children and elderly people exposed to E. coli O157:H7 may develop life threatening complication such as kidney failure clinical term refers to hemolytic uremic syndrome (HUS), but adults can recover within a week.

            The case of E. coli reported in health care facilities and hospitals originate from food served to patients while undergoing treatment in the facility and meat bought in the cafeteria(Friis, & Sellers, 2014). As a social science researcher at Good Health Hospital tasked with the responsibility of investigating the outbreak of nosocomial disease in Good Health Hospital in the past one year, the objective is to conduct Center of Disease Control (CDC) and Department of Health (DOH), regarding the recent incidents of nosocomial disease and develop a plan to prevent further spread and future outbreaks.

Infections outbreak at Good Health Hospital

            Recently, patients receiving treatment at Good Health Hospital located in Tampa Bay Florida were infected with E. coli in Ward 10, which is located in the second floor in the facility. The administrators of the health care facility immediately reported the incident to the Center for Disease Control and local Department of Health so as develop a plan for containing the spread of the disease within Good Health Hospital(Reed, & Kemmerly, 2009). The meeting with the chief administrator, Mr. Joe Wellborn and successful review of hospital records indicated that the number of patients infected were four and not six as earlier reported. Further examination confirmed that one of the patient was already symptomatic before admission at Good Health Hospital, which substantiate the sentiments that health care facilities operating within the jurisdiction of Tampa Bay Florida are susceptible to E. coli contamination. The preliminary findings calls for further investigation by DOH to ascertain severity of the infections.

            It was necessary to quarantine the four patients that were infected with E. coli in order to prevent the spread of disease in the health care facility. The affected patients were two females and two male and their races were two African-American and two Hispanic, aged between 15 to 42 years and that the cases were reported at different times(Macera, Shaffer, & Shaffer, 2013). Considering that the infection occurred at different times, it was challenging to determine the particular food items that lead to the breakout of the disease. Although, studies have shown that the severity of E. coli infection varies from individuals, children and elderly people are more susceptible and experience severe conditions of this nosocomial disease. A part from E. coli infection reported in Good Health Hospital, other health care facilities in Tampa Bay area have reported the outbreak of this nosocomial disease. This may be attributed to the fact that most of the health care facilities and hospital in Tampa Bay area contract one supplier to supply them with food items.             The meet ended with the conclusion that the administrators’ of Good Health Hospital should seek and contract an alternative supplier to deliver food items to the health care facility. In addition, the hospital should change their daily menu and include the provision of more salads, soup and pizza to the patients receiving treatment in Good………………………………………

1.      Refer to Table 5-3 on page 99. What are possible reasons for the observed differences in death rates between those of Hispanic origin and those not of Hispanic origin?

2.      Refer to the following estimated statistics for the US and Malaysia in 2005:

US:

Crude mortality rate = 800 per 100,000

 Crude birth rate = 14 per 1,000

 Life expectancy = 77.7 years

Malaysia:

Crude mortality rate = 500 per 100,000

Crude birth rate = 23 per 1,000

Life expectancy = 72.2 years

Can the lower crude mortality rate in Malaysia be explained by the fact that the US has a larger population? What factors could explain differences in birth rates and life expectancy?

3.      Which of these is an example of a ratio:

    Number of men who died from heart disease in a given year divided by the corresponding male population in the same year.

    Number of men who died from heart disease divided by the number of women who died from heart disease.

    Number of women taking an epidemiology class divided by the number of students in the class.

4.      How does prevalence proportion differ from incidence?

5.      What is the death-to-case ratio and how is it different from the case-fatality rate?
