Skin and soft infection tissue surveillance(Part 2)

As continuation for our previous discussion of Skin and soft infection tissue surveillance we will discuss the rest of the specific types of SST infections based on National Health Safety Network NHSN, we need to know the specific types of infection for the major type of SST infections and this need to be identified by a clear infection definitions this is what is present below for the skin and soft tissue surveillance Part 2.

Decubitus ulcer

Infection Patient has at least 2 of the following signs or symptoms with no other recognized cause:

redness, tenderness, or swelling of decubitus wound edges and at least 1 of the following:

a. organisms cultured from properly collected fluid or tissue

b. organisms cultured from blood. Infant pustulosis Pustulosis in an infant (≤1-year-old) can be diagnosed by:

  1. Infant has 1 or more pustules and physician diagnosis of skin infection.

  1. Patient has purulent drainage, pustules, vesicles, or boils. Or,

  2. Patient has at least 2 of the following signs or symptoms with no other recognized cause: pain , redness ,localized swelling, or heat and at least 1 of the following:

a. organisms cultured from aspirate or drainage from affected site

b. organisms cultured from blood

c. positive laboratory test performed on infected tissue or blood (e.g., antigen tests for HSV, VZV)

d. multinucleated giant cells seen on microscopic examination of affected tissue

e. diagnostic single antibody titer (IgM) or 4-fold increase in paired sera (IgG) for pathogen.

Soft tissue infection

ST infections must have one of the following criteria:

  1. Patient has organisms cultured from tissue or drainage from affected site.

  2. Patient has purulent drainage at affected site.

  3. Patient has an abscess or other evidence of infection seen during an invasive procedure or histopathologic examination.

  4. Patient has at least 2 of the following signs or symptoms at the affected site with no other recognized cause: localized pain or tenderness, redness, swelling, or heat and at least 1 of the following:

a. organisms cultured from blood

b. positive laboratory test performed on blood or urine (e.g., antigen tests for H influenza, Group B Streptococcus, or Candida spp)

c. diagnostic single antibody titer (IgM) or 4-fold increase in paired sera (IgG) for pathogen.

Omphalitis

Omphalitis in a newborn (≤30 days old) must meet at least 1 of the following criteria:

  1. Patient has both erythema and purulence at the umbilicus.

  2. Patient has erythema and/or serous drainage from umbilicus and at least 1 of the following:

a. organisms cultured from drainage or needle aspirate

b. organisms cultured from blood.
