Team 2: Wild Wild West Elizabeth Acord Jason Baldick Miriam Beecham Jenny Murray
Background Our Case A patient returns from a trip to Costa Rica and about 8 days later starts experiencing flu-like symptoms Patient sees their primary care doctor and is diagnosed with the flu, told to take ibuprofen and get some rest Patients condition worsens Patient consults WebMD
Health Maintenance/Disease Management
Workflow in System 2 (Cerner) Start of Physician Note Documentation is mix of both structure and Free text
Note Continued Information such as Allergies and Current Medications pre-populate Note This Information is updated at admission but should be non-encounter specific
Physician Note Conti Physical is documented within not utilizing structured and non-structured documentation
Note Continued After Eval; The diagnosis is made of an upper Respiratory Infection. (This is linked to ICD-9 code) This will be encounter specific and not travel with the patient as a problem would.
Next Steps Patient returns to primary care doctor, questioning diagnosis given recent travel history. Primary care doctor tells them to increase dosage of ibuprofen. Patient seeks out infectious disease specialist. Patient is tested for malaria. Patient shows decreased kidney and liver function, and severe dehydration. Patient is hospitalized. Patient shows decreased kidney and liver function, and severe dehydration. Patient is hospitalized. Correct diagnosis of leptospirosis is made. Patient is given appropriate antibiotics.

What is Leptospirosis? What is leptospirosis? Leptospirosis is a bacterial disease that affects humans and animals. It is caused by bacteria of the genus Leptospira. In humans it causes a wide range of symptoms, and some infected persons may have no symptoms at all. Symptoms of leptospirosis include high fever, severe headache, chills, muscle aches, and vomiting, and may include jaundice (yellow skin and eyes), red eyes, abdominal pain, diarrhea, or a rash. If the disease is not treated, the patient could develop kidney damage, meningitis (inflammation of the membrane around the brain and spinal cord), liver failure, and respiratory distress. In rare cases death occurs. Many of these symptoms can be mistaken for other diseases. Leptospirosis is confirmed by laboratory testing of a blood or urine sample.
How do people get it? Outbreaks of leptospirosis are usually caused by exposure to water contaminated with the urine of infected animals. Many different kinds of animals carry the bacterium; they may become sick but sometimes have no symptoms. Leptospira organisms have been found in cattle, pigs, horses, dogs, rodents, and wild animals. Humans become infected through contact with water, food, or soil containing urine from these infected animals. This may happen by swallowing contaminated food or water or through skin contact, especially with mucosal surfaces, such as the eyes or nose, or with broken skin. The disease is not known to be spread from person to person.
How long is the latent period? The time between a person's exposure to a contaminated source and becoming sick is 2 days to 4 weeks. Illness usually begins abruptly with fever and other symptoms. Leptospirosis may occur in two phases; after the first phase, with fever, chills, headache, muscle aches, vomiting, or diarrhea, the patient may recover for a time but become ill again. If a second phase occurs, it is more severe; the person may have kidney or liver failure or meningitis. This phase is also called Weil's disease. The illness lasts from a few days to 3 weeks or longer. Without treatment, recovery may take several months.
Where is it found? Leptospirosis occurs worldwide but is most common in temperate or tropical climates. It is an occupational hazard for many people who work outdoors or with animals, for example, farmers, sewer workers, veterinarians, fish workers, dairy farmers, or military personnel. It is a recreational hazard for campers or those who participate in outdoor sports in contaminated areas and has been associated with swimming, wading, and whitewater rafting in contaminated lakes and rivers. The incidence is also increasing among urban children. Travelers participating in recreational water activities, such as whitewater rafting, adventure racing, or kayaking may be at increased risk for the disease, particularly following periods of heavy rainfall or flooding and even in areas not previously considered endemic (3). Recent outbreaks of leptospirosis in the US have occurred in Illinois and Florida (CDC, unpublished data), while leptospirosis is endemic to Hawaii (4,5). Outbreaks in which US residents acquired leptospirosis have also occurred recently in Malaysian Borneo and Costa Rica (2,6).
Re-emerging Disease Infection in U.S. seems to be on the rise in urban areas and due to increased water recreation (Reemerging Leptopsirosis, California 2004) In the U.S cases reported per year, but still the most widespread zoonotic disease globally (Reemerging Leptopsirosis, California 2004) CDC issued an alert after Hurricane Katrina (CDC)
How do you treat it? Leptospirosis is treated with antibiotics, such as doxycycline or penicillin, which should be given early in the course of the disease. Intravenous antibiotics may be required for persons with more severe symptoms. Persons with symptoms suggestive of leptospirosis should contact a health care provider.
Can it be prevented? The risk of acquiring leptospirosis can be greatly reduced by not swimming or wading in water that might be contaminated with animal urine. Protective clothing or footwear should be worn by those exposed to contaminated water or soil because of their job or recreational activities.
Rare Diseases About rare diseases, compared to about 600 common conditions. (Keuhn 2008) Rare disease is defined as affecting fewer than 200,000 in U.S. (Keuhn 2008) NIH has just launched NIH Undiagnosed Diseases Program this year to help patients get diagnosed (Keuhn 2008) Delay in diagnosis can have long-term impact on patients health. According to the European Organization for Rare Diseases (EURORDIS): the period between the emergence of the first symptoms and the appropriate diagnosis involves unacceptable and highly risky delays, as well as the wrong diagnosis lead to inaccurate the treatments…
