Film Array Gastrointestinal Panel Compared to Usual Care for ED Evaluation of Infectious Diarrhea
Film Array Gastrointestinal Panel Compared to Usual Care for ED Evaluation of Infectious Diarrhea
This research study will test a laboratory test called Film-Array Gastrointestinal (GI)
 Panel. This GI Panel is a test that can identify the bacteria or viruses that may cause
 diarrhea. This test will enable the ED doctor to better understand the cause of diarrhea to
 try to determine the best treatment.

 The primary objective of this study is to determine if testing ED patients who complain of
 diarrhea will lead to more optimal use of antibiotics. Optimal use of antibiotics is defined
 as the most appropriate antibiotic to treat a specified pathogen.
Inclusion Criteria:

 -  Presumed infectious diarrhea (3 or more loose stools in past 24 hours)

 -  Must have one of the 3 following features or symptoms lasting more than 7 days.

 1. Symptoms greater than 24 hours;

 2. Dehydration (defined as the need for intravenous fluid or per clinician's
 judgement ((based on the general appearance and alertness of the patient, the
 pulse, the blood pressure, the presence or absence of postural hypotension, the
 mucous membranes and tears, sunken eyes, skin turgor, capillary refill, and
 jugular venous pressure.))

 3. Inflammation (defined as fever (greater than 100.1), blood in stool per patient,
 DRE, or tenesmus.)

 Exclusion Criteria:

 -  Chronic Symptoms (>14 days)

 -  Inability to Follow- Up (i.e. no telephone)

 -  Prisoner

 -  Likely non-infectious cause of diarrhea (Crohn's disease, radiation colitis, irritable
 bowel syndrome, or celiac disease)
