Increasing the efficiency of a targeted methicillin-resistant Staphylococcus aureus screening program.

Area of Science:

• Infectious Disease
• Clinical Microbiology
• Healthcare Management

Background:

• Healthcare-associated infections, such as methicillin-resistant Staphylococcus aureus (MRSA), necessitate effective screening protocols.
• Contact isolation for MRSA patients can increase healthcare costs and impact patient experience.
• Traditional culture-based screening methods can be time-consuming and less efficient.

Purpose of the Study:

• To evaluate the impact of transitioning from a 2-step culture-based protocol to a single polymerase chain reaction (PCR) test for MRSA screening.
• To assess the efficiency and cost-effectiveness of an enhanced MRSA screening program.
• To reduce unnecessary contact isolation by improving the speed and accuracy of MRSA detection.

Main Methods:

• An interdisciplinary team redesigned an existing MRSA screening program.
• The protocol was changed from a 2-step culture method to a single-step PCR testing approach.
• Program efficiency and cost implications were analyzed before and after the protocol change.

Main Results:

• The screening program's efficiency increased from 77% to 100% after adopting PCR testing.
• Despite the higher initial cost of PCR assays, the overall program remained cost-saving.
• The shift to PCR testing streamlined the screening process and improved resource utilization.

Conclusions:

• Single-step PCR testing is a highly efficient method for MRSA screening in targeted patient populations.
• Implementing PCR-based MRSA screening can optimize healthcare resource allocation and maintain cost-effectiveness.
• This strategy supports reducing unnecessary isolation measures while ensuring patient safety.
