The Evidence That Changed Everything

Research from Nguyen et al. (2026) tracked 255 perioperative staff across a major hospital system during a targeted sustainability education campaign. Before the education programme, only 57.4% of staff felt knowledgeable about operating room sustainability, despite 90.8% expressing motivation to improve environmental practices.

The knowledge gap wasn't uniform. Surgeons were 3.77 times less likely than nursing staff to feel knowledgeable about sustainability (95% CI 2.01-7.06, P < 0.0001). Younger staff showed lower knowledge levels than their older colleagues.

After the education programme, knowledge levels jumped to 87.9% across all staff groups. The post-education analysis showed no differences between surgeons and nurses, or between age groups. The education had successfully levelled the playing field.

The Surgeon Motivation Challenge

The most striking finding was the motivational divide. Surgeons were 2.6 times less likely than nursing staff to feel motivated about improving OR sustainability (95% CI 1.33-5.09, P = 0.006). Even when surgeons recognise environmental issues, translating that awareness into action presents unique challenges.

The data revealed generational preferences around scrub cap choice. Younger staff were less likely to prefer single-use scrub caps compared to older colleagues (OR 2.06, 95% CI 1.16-3.64, P = 0.01). This suggests environmental consciousness may be higher among emerging generations of healthcare workers.

Preference for single-use caps remained relatively stable throughout the education programme — dropping only slightly from 40.2% to 37.5%. This suggests that changing institutional policy may be more effective than attempting to shift individual preferences.

Why This Matters for Your Theatre Team

This study provides the first evidence-based roadmap for hospitals wanting to implement sustainable scrub cap policies. The success wasn't just about environmental benefits — the hospital achieved nearly £1,000 in cost savings within six months by purchasing 31,200 fewer disposable caps.

We know from meta-analysis research that reusable surgical headwear is both safer and more environmentally sustainable than disposable alternatives. This study adds the missing piece — how to successfully implement policy change within existing hospital systems.

The education programme's success in eliminating knowledge gaps between different professional groups suggests that resistance to reusable scrub caps often stems from information deficits rather than fundamental opposition. When staff understand the evidence, policy change becomes feasible.

For theatre managers and sustainability coordinators, this research demonstrates that targeted education can be a powerful tool for overcoming institutional inertia. The key appears to be addressing specific knowledge gaps within different professional groups rather than assuming uniform understanding across the perioperative team.
