Clinical Characteristics and Outcomes in Patients Diagnosed With Novel Influenza A (H1N1)

• To describe the clinical characteristic and outcomes of the patients admitted to UPMC Presbyterian campus with infection due to novel influenza A (H1N1). [ Time Frame: 5 year ]
  

• To identify risk factors for admission to the ICU and mortality [ Time Frame: 5 years ]
  

Patients diagnosed with H1N1 will be asked to consent and allow us to collect the following:

From the medical record the research staff will review and record the results of the test/procedures (x-rays, CT-scans, EKG (electrocardiogram), etc.) that are part of the subjects clinical care and the results will become part of the research record. We will also collect and record vitals signs, including temperature, blood pressure, heart rate, respiratory rate and record the list of medications the subject is taking. We will also collect information on demographics (address, phone number, etc.) including gender, race and ethnicity, review and record past medical history and any non medical procedures that the subject may have had within the past two months. This information will be collected by the research coordinator from the medical record.

The clinical physician ordered a nasopharyngeal swab or obtained bronchoalveolar lavage fluid to diagnose novel Influenza A (H1N1). We will collect this swab or fluid after the diagnosis has been made, to evaluate the genetic material of the virus. This swab or fluid is normally discarded once the diagnosis is made.

collection of data will be done by the research staff and should not take any longer than 15-20 minutes. The clinical samples that would have been discarded will be collected by the research staff from microbiology and pathology and delivered to the research lab in Scaife.

The investigators will do a 6 month follow up phone call to check the health status of the participant. This will be done by the research coordinator and take no more than 5-10 minutes of the subject's time.
