MRSA Isolates and E Test

Centegra lab will now perform an e-test on all MRSA isolates obtained from a sterile site with microscan mic >=2.

With additional testing e-testing many isolates may have lower had mic of <1.5 expanding options for treatment.

This additional step will take an additional day to report out.

Oral and Nasopharyngeal Specimen Collection


This is a brief list of oral and nasopharyngeal specimen collection procedures.

MRSA

  • Location: Anterior nares
  • Swab: Routine cotton culture swab

Top

Influenza

  • Location: Posterior nasopharynx
  • Swab: Routine cotton culture swab
  • Wear a surgical mask, protective eye wear and gloves while collecting the specimen
  • Place the patients head on the bed pillow or against a wall so that they do not move backwards
  • The swab will go straight backwards like placing an NG tube, it should go the distance between the nostril and the ear into the throat.
  • The swab is rotated for a bout 5–10 seconds to get enough epithelial cells on it
  • Remove the swab and place it in the transport media and sent it to lab

Pertussis

The PCR assay reuires a special swab, made of aluminum with a nylon tip. Traditional cotton tip swabs interfere with the test

  • Location: Posterior nasopharynx
  • A special transport media is needed- call the lab for it
  • Wear a surgical mask, protective eye wear and gloves while collecting the specimen
  • Place the patients head on the bed pillow or against a wall so that they do not move backwards
  • The swab will go straight backwards like placing an NG tube, it should go the distance between the nostril and the ear into the throat. This is different from a nasal swab for MRSA or influenza
  • The swab is rotated for a bout 5–10 seconds to get enough epithelial cells on it
  • Remove the swab and place it in the transport media and sent it to lab

Pertussis-2

Mumps

  • Location: Specimen is collected from the parotid duct secretions preferrably within 9 days of symptoms.
  • Swab: Routine cotton swab. Specimen is sent in a viral transport media.
  • Steps
    • Massage the parotid gland for 30 seconds. Note that it is just in front of the ear lobe. CDR742039
    • Specimen should be collected from the parotid duct opening just next to the second molar.

A lecture on outbreaks in extended care facilities

This is the screen cast of a lecture titled “Outbreaks in extended care facilities (ECF)” given by Irfan Hafiz MD on April 19th 2013 at Centegra McHenry Hospital. It was co-sponsored by Centegra Health System and the McHenry County Dept. of Health.

Topics included in the lecture include:

  • Identifying current and emerging infectious disease common to long term care facilities (LTCF).
  • Describe preventive interventions for infectious disease in the context of LTCF.
  • Describe the unique challenges facing LTCF in the context of infectious diseases.

For upcoming lectures please look at the calendar and filter by “Education Events”.

MRSA control lecture – Audio and slides

MRSA – why do we do what we do?

The lecture

I recently presented a 30 minute lecture on MRSA control in the hospital setting at the fall symposium sponsored by Centegra Health System. The lecture describes the background of how MRSA is spread within medical facilities, the effects of its spread and measures that can be used to control it. The lecture also goes over some of the success stories of what an MRSA control program can expect to achieve. I also cover some of the historical background of how something as basic as hand washing became an actual event in medical history. I closed the lecture with some questions from the audience.
