Airborne infection isolation room (AIIR) (FKA negative pressure isolation room) * Is a single-occupancy patient-care room used to isolate persons with a suspected or confirmed airborne infectious disease * Environmental factors are controlled in AIIRs to minimize the transmission of infectious agents that are usually transmitted from person to person by droplet nuclei associated with coughing or aerosolization of contaminated fluids * AIIRs should provide negative pressure in the room (so that air flows under the door gap into the room); and an air flow rate of 6-12 ACH ( 6 ACH for existing structures, 12 ACH for new construction or renovation); and direct exhaust of air from the room to the outside of the building or recirculation of air through a HEPA filter before returning to circulation

* According to Joint Commission on Accreditation of Healthcare Organizations (JCAHO) (www.jcaho.org) requires the following five components of an infection control program for accreditation: 1. Surveillance: monitoring patients and healthcare personnel for acquisition of infection and/or colonization 2. Investigation: identification and analysis of infection problems or undesirable trends 3. Prevention: implementation of measures to prevent transmission of infectious agents and to reduce risks for device and procedure-related infections 4. Control: evaluation and management of outbreaks 5. Reporting: provision of information to external agencies as required by state and federal law and regulation

* Patient room, equipment, treatment and diagnostic must be: 6. Single patient room (containing a private bathroom) with the door closed 7. Facilities should maintain a log of all persons entering the patient's room 8. Consider posting personnel at the patient’s door to ensure appropriate and consistent use of PPE by all…...

Airborne Honey

...imported Manuka Honey, Korean consumers couldn’t buy affordable Manuka Honey in any supermarkets.   II. So why did Emart choose to import from Airborne Honey as its first Manuka Honey? a. We chose Airborne Honey because of their credibility in two main areas: i. Airborne Honey is New Zealand’s oldest honey company at 102 years old. ii. Airborne Honey has a great quality control system, where they focus on 3 specific points: 1. They test exactly how much pollen is in every batch, and guarantee all honeys meet international CODEX standards (UN FAO/WHO guidelines). 2. Airborne Honey uses a patented system that produces undamaged, natural honeys with extremely low heat damage. 3. Airborne Honey has a very detailed traceability system, where they can tell customers exactly where their honey came from---and pinpoint it on a map of New Zealand a. For example, instead of saying a general location, such as “Your honey came from the Seoul area of Korea, Airborne could say that this particular jar of honey came from beehives on the backside of the King Sejong statue at Gwanghwamun.” b. Because Korean consumers are very sensitive these days about honey quality, we felt that Airborne Honey could give them the confidence in high quality products for affordable prices they have been looking for.   i. One thing that consumers might not know is that Airborne Honey not only measures honey pollen count, but also tests for color grade, mineral level, and sugar profiles---and so can test to see......

...Airborne Jumping out of an airplane is a life experience one will never forget. People have different reasons for doing it. Some people skydive for the sport of it. It is an exhilarating and adrenaline pumping experience. I jumped out of an airplane to earn my airborne wings in the army. It all started in Airborne School, during ground week, where we were taught how to land safely and dawn a parachute. During tower week, the second week of training, we learned pre-jump preparations and how to properly exit an airplane. Finally, the third week of training came: jump week. My classmates and I made five jumps from a C130 aircraft. Two of the jumps were with just a parachute, known as Hollywood jumps. Two of the jumps were with full combat loads. One of the combat jumps had to be at night so that we could earn our jump wings. I woke up at “zero dark thirty”; a phrase that means before dawn in the army. I rolled out of bed sore from the two weeks of five mile runs every morning in full uniform and boots. My legs hurt from jumping from platforms and throwing myself to the ground learning to land correctly. I stood in formation, half asleep, while the airborne instructors briefed us for the events of the day. The airborne instructors are called Black Hats because of the black baseball caps that they wear with their rank and wings pinned to the front. That morning, our class had to jog three miles to the air field to get our Jump Master brief. I felt a slight chill in my bones...

Airborne Express

...Airborne Express In the 1990’s, express mail was a profitable business, where individuals were spending almost $17 billion to ship items. Shipment volumes had increased 15-20% every year over the last ten years too. The three main shipping companies at this time were Federal Express, UPS, and Airborne Express. Airborne Express was the third largest shipping company during this time. Compared to UPS and Federal Express, Airbone needed to focus on the importance of service and speedy delivery to grow. Because the express shipping industry began to attract more business, UPS and Federal Express began a pricing war, resulting in Airborne’s ability to gain margins. Airborne Express was able to produce profits during this time by using its own sources of competitive advantage: 1. Continue to service companies who needed to ship large volumes of urgent item materials. 2. Less automation and more employees for sorting, allowing the company to hire more part time employees instead of full time. 3. Shipping was mainly in metropolitan areas, which allowed them to concentrate on afternoon deliveries or second day deliveries. 4. Allowed other companies to release new technology for the field and then would order the devices for Airborne, rather than paying for R&D up front. 5. Reduced operating costs by: owning its own airport to ship the items for customers, as well as utilizing older aircraft for shipping, no retail centers to maintain, and had......

Prevention and Control of Nosocomial Infections

...Prevention and Control of Nosocomial Infections A Nosocomial Infection is a very distinct infection that occurs in hospital environments. The work nosocomial literally means – of or relating to a hospital. Also known as hospital-acquired infections (or HAI) these occur in unsanitary or unclean hospital environments and can be contracted by hospital staff, hospital patients and visitors. Infections can be generally described as bacterial or fungal. Nosocomial infections will often cause urinary tract infections, and pneumonia among other things depending on the patient’s reaction to the infection. Many elements go into the cause and spread of nosocomial infections and, according to epidemiologic research, occur on an international level affecting people in the United States and abroad. Nosocomial infections may arise due to a lack of sterilization, improper or negligent procedures or simply accidental contraction. Prevention of nosocomial infection has steadily with the progress of modern medicine. Currently, there are specialists who examine the history, spread and prevention of nosocomial infections as it immediately affects the well-being of all parties involved and can be hazardous to the professional status of a facility. ...

Infection

...INTRODUCTION Infection remains the main cause of morbidity and mortality in man, particularly in developing areas where it is associated with poverty and overcrowding.In the developed world increasing prosperity, universal immunization and antibiotics have reduced the prevalence of infectious disease. However, antibiotic-resistant strains of microorganisms and diseases such as human immunodeficiency virus (HIV) infection, variant Creutzfeldt–Jakob disease ,avian influenza and severe acute respiratory syndrome(SARS) have emerged. In the developing world successes such as the eradication of smallpox have been balanced or outweighed by the new plagues. Infectious diseases cause nearly 25% of all human deaths. Two billion people one-third of the world’s population are infected with tuberculosis (TB),500 million people catch malaria every year, and 200 million are infected with schistosomiasis. 39.5 million people are living with HIV/AIDS, with 4.3 million new HIV infections in 2006 (65% in sub-Saharan Africa). The eight Millennium Development Goals (MDG) hope to be achieved by 2015. These are: eradicating extreme poverty and hunger, universal primary education, gender equality and empowerment of women, reduction in child mortality,improvement in maternal health, combating HIV/AIDS,malaria and other diseases, ensuring environment sustainability and developing global partnership for development.

Chain of Infection

...facilitate this process? Give a specific example. Use an example that is different than the postings of other students.   There are six links in the Chain of Infection. Those areas include:  1. The infectious agent itself-  2. The reservoir where the infectious agent can live and multiply or lie dormant until the organism can find the opportunity to cause disease  3. The susceptible host  4. A means of Transmission 5. A portal of exit  6. A portal of re-entry    Each link in this chain must be intact for a disease to be transmitted and infect another person. There is the potential to defeat a communicable disease process by disrupting the link in this chain at any point along the way thus preventing infection in another person.  An example of the simplest chain of infection is an infected patient cared for by a health care worker who doesn't wash their hands before caring for another patient. Human sources of microorganisms are healthcare workers, patients themselves and visitors, any of whom may be individuals who are in some stage of an incubation period of a disease process, may already have a disease, or may be a chronic carrier of an infectious agent. The patient may be their own source of infection. (Baldwin, 2008)   The bacteria must be able to find a susceptible host. Some individuals are immune to infection or are able to resist colonization by an infectious agent while others will develop a full blown clinical disease process. Then there are those who......

...2011 Airborne Express EMI and the CT scanner Juan Perez Strategic Management Juan Perez Strategic Management |Airborne Case 1 Strategic Management 6/7/2011 First Case Analysis: Airborne Express Analysis of the Express Mail Industry: In order to have a clear understanding of Airborne’s position and to make recommendations about future moves, it is critical to examine the industry environment—competitors, customers, and suppliers—and examine the firm internally. To do so, the Porter’s five forces framework and a resource & capability analysis will be utilized. Threat of Substitutes: In today’s aggressive environment, product substitutes are regarded as one of the most threatening forces in competition. In the case of Airborne, it wasn’t the exception. There were other two main players (Federal Express and United Parcel Service) offering similar a similar service –express mailing. The availability of substitutes made the demand for this industry elastic. The case also states that large customers weren’t known for their loyalty for a single carrier, once the contract was up, they look for the best bidder. Threat of Entry: The existent barriers of entry made hard for companies to enter the express mail industry. The costs of becoming established in this industry were so large that discourage potential entrants. For instance, a company entering this industry would have to incur large upfront costs to operate, such as constructing a hub and several spokes, and......

Airborne Express

...Summary: After a highly successful quarter in the extremely competitive express mail industry, Airborne Express managers are assessing the firm’s current competitive position within the shipping industry. Although they are a much smaller company than their two main competitors, UPS and FedEx, they are looking to see how they can continue to maintain their healthy growth in the industry. Airborne is in a unique position, as they are significantly smaller than their major competitors, but still have managed to acquire a high position in the market. How can they continue this growth? Opportunities -International expansion needs with increased globalization in commerce. -Partnership with RPS as a way to increase ground delivery network while still maintaining low costs for clients -Major opportunity to be seen as a “low cost” alternative to premium carriers FedEx and UPS, as Airborne has a much more efficient target clientele. Provide a minimal “bells and whistles” service to their clients with low overhead costs. STRATEGY Ground delivery services: Airborne should continue to “hand select” their clients based on mutually beneficially needs; clients’ needs for cost-efficient and personalized shipping, and Airborne’s need for customers with relatively consistent shipping needs to help keep their costs down. -Start by continuing to leverage their partnership with RPS, which could help them harness some economies of scale cost advantages more similar to their larger......

Nosocomial Infections

...Nosocomial Infections By princessbec76 | Studymode.com Section 1: Infections in Healthcare Settings Essay. Nosocomial infections, hospital acquired infections, are an on-going concern to healthcare professionals. These infections are one of the major causes of death in hospitalised patients and are a significant burden on not only the patient’s and the public’s health (as organisms causing nosocomial infections can be transmitted to the community through discharged patients, staff and visitors) but also the economy. A nosocomial infection is an infection acquired at least 72 hours after being admitted into hospital for any reason other than the infection or one which develops amongst hospital staff. Infections are also identified as nosocomial if they appear in a patient within 30 days after their discharge from hospital. Non nosocomial infections, community acquired infections, are infections acquired anywhere other than the hospital. The most common places where non nosocomial infections occur are schools, day care centres and sports facilities. They are spread through skin to skin contact, cuts and grazes, overcrowding and poor hygiene. The illnesses or infections can be the same, for example, pneumonia or gastroenteritis but it is the setting that they are contracted in which differentiate the two infections. Nosocomial infections occur worldwide and affect both wealthy, developed countries as well as the poorer ones with scarce resources. A survey conducted by the......

Airborne Case

...------------------------------------------------- Airborne Express Case 1. How has Airborne survived, and recently prospered in its industry? Please address why you think it was difficult for bigger competitors such as FedEx to imitate Airborne’s strategy. Although Airborne does not get the publicity that FedEx and UPS get, they have managed to remain the third largest player in the express mail industry. One unique aspect that has helped Airborne maintain a leading position in the industry is their ownership of an airport, which serves as their major hub. This is a huge advantage because they have complete control over the timing of each shipment and what comes in and out of the airport. Airborne also purchases and modifies used aircrafts, which saves costs and allows them to run roughly 15% more full than their competitors. Onsite at the airport, Airborne leases out warehouse space to their business customers, which allows for quick delivery on last minute orders. This is a unique offering in which their competitors cannot match without purchasing an airport. Another important aspect of Airborne that helps maintain their position in the industry is their selective process for choosing customers. Ray Berry, vice president of Field Services Administration at Airborne, was quoted stating, “We pick our kind of customer deliberately.” (Rivkin, 11) The company would purposely pass over business with customers who didn’t fit their vision. Airborne mainly targeted “the......

Infection Control

...Nosocomial infections refers to infections acquired during hospitalization, with symptoms usually occurring within forty-eight hours after admission. The origin of nosocomial infections can be attributed to the following: - Bacterial flora already present in the patient; - Microorganisms from the environment through transmission from: carriers colonized at admission, admitted to wards without undergoing surveillance, isolation or eradication of the germ(s); patients who have developed the infection but who have not been isolated;contact with contaminated objects and surfaces; medical personnel, usually via their hands; invasive procedures such as the installation or maintenance of a device(1). The current probability of infection in health-care facilities is relatively high, and the risk of death is not negligible. Data from the National Institute of Health (NIH) indicates that 4 million such infections occur in America every year, causing around 37,000 deaths. According to a study carried out by the Global Patient Safety Challenge: Clean Care Is Safer Care, at any one time more than 1.4 million people in the world are suffering from nosocomial infections. In developed countries, there is an incidence of 5%–10% in the total number of inpatients. Hospital infections are also a major economic challenge for public health-care systems due to the impact they have upon health-care costs(2). For example, infection by MRSA (methicillin-resistant Staphylococcus aureus) prolongs...
