Infection control including isolation

🔬 Practice-Changing Findings
Evidence from RCTs and meta-analyses published in the
last 12 months.
|
BMJ Open (2025) - Systematic Review
Key Findings
- Across 29 studies, patient satisfaction with IPC interventions ranged from 58.3% to 97.2%.
- Meta-analysis of four isolation-precaution studies found pooled satisfaction of 69% (95% CI 63.6% to 74.4%).
📋 Practice Implication: Isolation pathways should include clearer patient communication and feedback capture, because satisfaction during isolation is acceptable but not uniformly high.

Antimicrobial Resistance and Infection Control (2026) - Systematic Review
Key Findings
- With sterile covers in place, time explained only 8.5% of CFU variation and showed no significant linear association with contamination counts (p = 0.176).
- Analysis of mean CFU values likewise found only 7% of variation attributable to time, with no significant trend (p = 0.108).
📋 Practice Implication: Operating-room policies for covered sterile items can focus more on cover integrity and handling discipline than on arbitrary short time cutoffs alone.

Digestive Diseases (2026) - Systematic Review
Key Findings
- Nasopharyngeal MRSA carriage was associated with markedly higher PEG-site infection risk (odds ratio 24.31; 95% CI 5.20-113.65; p < 0.0001).
- Across 286 patients, this excess risk persisted despite only moderate heterogeneity between studies (I2 = 69%).
📋 Practice Implication: Pre-PEG MRSA screening can identify patients who warrant intensified contact precautions and infection-prevention measures around tube placement.

The Journal of Hospital Infection (2025) - Randomized Controlled Trial
Key Findings
- MAP-1-coated privacy curtains reduced total viable bacterial counts by 96.8% versus standard curtains (P<0.00001).
- MRSA counts were reduced by 99.3% versus uncoated curtains (P<0.00001), with more than 95% effectiveness sustained across each four-week period.
📋 Practice Implication: High-touch ward textiles such as privacy curtains are reasonable targets for antimicrobial surface strategies when environmental MDRO transmission remains difficult to control.

The Journal of Hospital Infection (2026) - Systematic Review
Key Findings
- Faecal microbiota transplantation improved CRE clearance versus controls (risk ratio 2.01; 95% CI 1.27-3.18) and VRE clearance (risk ratio 2.96; 95% CI 1.60-5.47).
- Selective digestive decontamination increased CRE clearance (risk ratio 2.47; 95% CI 1.32-4.63) but did not improve VRE clearance and was linked to increased antimicrobial resistance.
📋 Practice Implication: Outbreak plans for CRE or VRE can consider decolonization selectively, with more confidence in FMT-based approaches than in routine selective digestive decontamination.

Summary
Recent infection-control literature was strongest for multidrug-resistant organism containment, environmental reservoir reduction, and operating-room sterility practices. A randomized trial found large sustained reductions in bacterial and MRSA contamination on antimicrobial-coated privacy curtains, while meta-analyses supported targeted CRE/VRE decolonization strategies and identified MRSA carriage as a major predictor of PEG-site infection. Evidence directly addressing isolation itself was narrower, but patient-satisfaction data suggest isolation precautions remain acceptable for most patients when communication and care processes are handled well.
