MRSA screening

MRSA screening

The testing of all members of a particular group of individuals for (benign) cutaneous or nasopharyngeal colonisation by meticillin-resistant Staphylococcus aureus, to identify those at increased risk of healthcare associated infections, especially MRSA-bacteraemia following an intervention. The current standard in the UK is that all patients in certain groups (see table) undergoing elective procedures should be screened for MRSA. 

Patients needing MRSA screening 
• Burns patients
• Cardiothoracic
• High dependency unit
• Intensive care
• Neonatal
• Neurosurgery
• Oncology
• Orthopaedics patients

The logistics of MRSA screening and prophylaxis can become complicated with patients who need to travel to a (sometimes distant) center days ahead of surgery, especially if culture-based methods are used to detect MRSA.
The average cost per patient for the MRSA screening was US$11 (SD, 0), and the average cost per patient for the hand-made povidone-iodine nasal swabs was US$1 (SD, 0; Table 3).
Some tests may also be carried out such as MRSA screening and blood tests.
As with many infections, this success can be attributed to a number of clinical measures - namely cannula packs, the meticulous care of invasive devices, MRSA Screening (both admission and pre-admission screening) and appropriate and timely decolonisation of patients found to be MRSA positive."
Considering recommendations to move from universal to targeted MRSA screening in hospitals in England (6), more active surveillance of any identified case-patients or carriers of MRSA in the community may be warranted.
Isolation of SA, MRSA screening and anti-microbial susceptibility profile were done in the Pathology Department of the hospital according to Centre for Disease Control (CDC) guidelines.14 Samples were inoculated onto Mannitol-Salt Agar, followed by identification of SA by gram staining and biochemical tests such as catalase, coagulase and deoxyribonuclease (DNase).

The differences between the US and Western Europe regarding the implementation of ASC can be explained by different determinants, including (1) public health considerations and priorities, (2) availability of on-site microbiology laboratories, (3) factors related to healthcare systems and the influence of the market-driven healthcare industry, (4) cultural factors (e.g., proactive prevention vs reactive control measures), (5) local infection control practices and knowledge, (6) available resources dedicated to hospital hygiene, (7) legal constraints (e.g., mandatory MRSA screening in England), and (8) political commitment.
In addition, several states have passed or are considering legislation mandating the implementation of MRSA screening programs to reduce the risk to patients.
