Patient Safety & Team Communication
Communication failures occur in around 30% of operating theatre exchanges, and about a third of those failures have visible effects on patient safety (Lingard et al. 2004). Visible names and roles are a simple, studied way to help colleagues identify one another.

What the research shows about named caps
Staff who knew every colleague's name in theatre after labelled caps (107 staff, before and after)
Douglas et al. 2021Providers who knew colleagues' names with name-and-role caps (randomised, 20 caesarean deliveries)
Brodzinsky et al. 20211,420 labelled caps across one US academic medical centre: 66% of staff agreed the caps improved communication and 65% that they made it easier to talk to colleagues. No difference in surgical complication rates was found.
383 before, 212 afterSystematic review of five small studies: all reported better name and role recognition and perceived teamwork with labelled caps. The authors describe the evidence base as limited and heterogeneous.
Systematic review, 5 studiesInfection Control Evidence
Are reusable scrub caps as safe as disposables? The research is clear.
Meta-analysis found no significant difference in SSI rates between reusable and disposable headwear (OR: 0.79; 95% CI: 0.59–1.07)
Gumera et al.
Largest meta-analysis to date: 9 studies with 45,708 cases found no significant SSI difference
45,708 casesMarkel et al.
Cloth skull caps shed fewer particles and microbes than disposable bouffants
45,708 casesEvidence-based SSI prevention guideline does not specify disposable headwear
2017No evidence that headwear type affects SSI; bouffants least effective for particle containment
2018The commonly used disposable bouffant is the least effective for particle containment

Environmental Impact
The NHS uses approximately 2.4 million single-use caps in Scotland alone annually. Each takes up to 300 years to decompose.
79% lower carbon footprint over lifecycle
Single operations generate 150-170 kg CO₂e (equivalent to driving 720 km)
Dal Mas et al. 2024Each reusable cap replaces 200-250 disposables annually, preventing 2.5kg plastic waste per staff member
Dal Mas et al. 2024NHS sustainability context
- Operating theatres account for 4-5% of total healthcare carbon emissions
- Single-use items contribute 68% of surgical carbon emissions
- NHS Net Zero target: 2040 for direct emissions
- Switching to reusables could achieve 32% carbon reduction
