Rapid near-patient testing (NPT) for Clostridioides difficile infection (CDI) significantly cut patient isolation times and hospital stays. This approach also reduced antibiotic use and healthcare costs, improving patient management.
Area of Science:
- Infectious Diseases
- Healthcare Management
- Clinical Diagnostics
Background:
- Suspected Clostridioides difficile infection (CDI) management involves isolation, testing, and treatment.
- Current practices may lead to prolonged isolation, unnecessary antibiotic use, and increased costs.
- The study investigates the impact of rapid near-patient testing (NPT) on CDI management efficiency.
Purpose of the Study:
- To evaluate the effectiveness of rapid near-patient testing (NPT) in reducing patient isolation time.
- To assess the impact of NPT on hospital length of stay (LOS), antibiotic usage, and healthcare costs associated with CDI.
Main Methods:
- A 2-period pragmatic cluster randomized crossover trial involving 39 hospital wards.
- Primary outcome: patient isolation time; Secondary outcomes: hospital LOS, antibiotic therapy.
- Analyses included natural experiment (NE), intention-to-treat (ITT), and per-protocol (PP) approaches.
Main Results:
- NPT significantly decreased patient isolation time (NE: 9.4 hrs, ITT: 2.3 hrs, PP: 6.7 hrs).
- NPT led to significant reductions in hospital LOS (NE: 47.4%, ITT: 18.4%, PP: 34.2%).
- NPT resulted in cost savings of $25.48 per patient and reduced antibiotic use.
Conclusions:
- Implementation of CDI NPT significantly reduces patient isolation duration.
- NPT contributes to shorter hospital LOS and decreased antibiotic consumption.
- Rapid near-patient testing offers a cost-effective strategy for managing suspected CDI in hospitals.
