[EMBARGOED FOR July 11, 2013, ARLINGTON, Va.] A new guide developed by the Infectious Diseases Society of America (IDSA) and the American Society for Microbiology (ASM) will help physicians appropriately and accurately use laboratory tests for the diagnosis of infectious diseases. Laboratory test results drive approximately two-thirds of physicians' medical decisions.
Published today in the journal Clinical Infectious Diseases, the recommendations provide guidance regarding which lab tests are valuable and should be used in specific contexts; which add little or no value; and how to appropriately collect and manage specimens.
Laboratory diagnoses directly affect patient care and outcomes, as well as hospital infection control, patients' length of stay in the hospital, costs and laboratory efficiency.
"Getting the right diagnosis is contingent upon laboratory results that are accurate and clinically relevant," says Ellen Jo Baron, PhD, who worked with J. Michael Miller, PhD, to shepherd the guide to completion after its inception by Gary Doern, PhD. "Physicians, their staff and microbiologists must communicate and work together to ensure the best outcome for patients, and this guide aims to help facilitate this collaboration."
Divided into sections on anatomic systems (including infections of the bloodstream, cardiovascular system, central nervous system, eyes, soft tissue of the head and neck, upper and lower respiratory system, gastrointestinal tract, abdomen, bone and joints, urinary tract, genitals and skin and soft tissues) and etiologic agent groups (tickborne infections, viral syndromes, blood and tissue and parasite infections), the guide helps physicians decide what tests to request when they suspect specific agents are causing disease. It also provides targeted recommendations and precautions regarding selecting and collecting specimens, detailing what is required for various cultures and tests, as well as the appropriate collection device, temperature and ideal transport time.
The guide suggests 10 tenets of specimen management that everyone involved from physician to nurse to laboratory scientist should follow for good patient care. These include:
Guidance provided in the document is not intended to take the place of a doctor's judgment, but rather to support the decision-making process, which must be individualized according to each patient's circumstances.
