This page advises healthcare professionals working within the community, care homes or hospital environments on how to reduce the risks of hot weather to the health of people they provide care for.

Some people will rejoice at the thought of hot weather coming our way. But for nursing staff, keeping hydrated while at work can bring another challenge to already busy days. Royal College of Nursing Head of Health, Safety and Wellbeing Kim Sunley answers your questions on this key subject.

In operating theatres and other high pressure clinical environments, clear identification shouldn’t be a nice ‘extra’, it is a patient safety need. When staff cannot quickly recognise names and roles, communication becomes harder, escalation can be delayed and patients are left unsure who is caring for them. Reviews of patient safety repeatedly show that poor teamwork and unclear roles can contribute to avoidable harm. Danielle Checketts, Managing Director of Eco Ninjas, discusses why being able to identify staff by their names and roles is so important not only for the staff themselves but also patients. She explains how a simple idea, reusable hats with detachable name badges that can be removed before laundering, can support safety and teamwork. In theatre, everyone can look the same. Masks, gowns, visors and lead aprons often cover name badges, while lanyards are easily hidden or turned around. Theatre teams include surgeons, anaesthetists, students, agency staff and industry representatives, yet patients and colleagues are still expected to know who is who. When names, roles and seniority are unclear, questions may go to the wrong person, and valuable seconds can be lost. Even when introductions are made during the WHO surgical safety checklist,[1] names and roles can quickly be forgotten once a procedure is underway. In an emergency, it must be immediately clear who is who. This lack of clarity can lead to: Miscommunication at critical moments. Delays in escalation. Reduced patient confidence and psychological safety. Errors due to misunderstood roles or instructions. This isn’t just theoretical. Liz Fitzhugh, net zero lead and former theatre manager at University Hospitals Coventry & Warwickshire (UHCW), put it simply: “If a patient arrests and someone asks for the crash trolley, either everyone goes or no one goes.” In critical moments, teams need to be immediately identifiable so they can act without hesitation. Liz’s team at UHCW were among the first to introduce name and role theatre caps in 2019. It feels fitting that she was also the person who once asked me to write my name on my disposable cap with a marker pen, quietly sparking the idea that grew into this work. For years, poor identification in theatre has become accepted and been treated as normal. But it shouldn’t be. Patients want to know who is caring for them, and staff work more safely when names and roles are clearly visible. That is why the ‘theatre cap challenge’ gained momentum internationally, highlighting a simple idea: if the hat remains visible when wearing sterile attire, it can help make names and roles visible too. Patient perspectives: what matters most Patients consistently say they want to know who is in the room, who is leading their care and who they can turn to for reassurance. Feedback from surgical and maternity care journeys, including caesarean births, shows that visible names and roles help people feel safer, calmer and better able to engage in what is happening around them. Patients describe feeling more reassured when: Staff introduce themselves clearly. Visible names and roles help patients and colleagues remember who is who after introductions, rather than relying on memory alone. There is consistency in communication throughout their care. When identification is unclear, patients can feel anxious and excluded at the point they are most vulnerable. Visible names and roles do more than support courtesy, they strengthen communication, teamwork and reassurance for patients and families. Infection prevention, hygiene and practical constraints Efforts to improve identification must also align with infection prevention standards. Theatre attire cannot simply be adapted without considering contamination risk, laundering processes and the wider pressure to reduce reliance on single use items. The challenge with current approaches The current embroidered theatre caps improve visibility of names and roles, but they are difficult to manage at scale and fail to support consistent identification for all staff. Students, visitors and temporary staff are often excluded, and new starters can wait months before receiving one. They also create ongoing operational challenges, including time-consuming bespoke ordering, poor fit, loss and replacement costs, outdated roles, and complications with laundering. As Alan Dickens, Theatre Manager at MMUH Birmingham, explains: “Bespoke embroidered caps are hard to manage over time. When staff leave or change roles, the hats issued to them often leave with them or need replacing. This creates ongoing cost for the trust and delays in maintaining accurate identification.” Emerging responses across the NHS Several NHS organisations are now testing a more practical approach: reusable hats with detachable name badges that can be removed before laundering. This keeps identification visible while fitting more easily into real hospital systems. In Somerset, a pilot at Musgrove Park showed how a simple change can support safety and teamwork. Mr Andy Stevenson, orthopaedic consultant at Somerset NHS Foundation Trust, said: “In theatre, there can be a really high turnover of colleagues at times, with new people coming and going all the time. This can make it really difficult to know who is who, let alone what jobs they have. Some days, it will be the first time working with half the people in the room. The badge hats have helped to positively transform communication and safety.” A similar message has come from maternity services. Kathryn Harrison, delivery suite manager at Great Western Hospital, said: “Despite staff introducing themselves in the morning, remembering everyone’s name and role throughout the day is challenging, especially when more than 12 people can be in the room at any one time. The badge hats reinforce this critical stage in safe surgery, improve teamwork and communication, and help break down hierarchical barriers. They can be worn by all staff, students, birthing partners and even the patients wear them on our unit”. Building the evidence base There is growing research interest in identification in healthcare.[2][3][4] We have started to work with medical schools on exploring the impact on training environments, role visibility and communication. This is helping to strengthen the evidence base for scalable, system-wide approaches. Students can be included simply using a badge with their name and role alongside a standard fitted hat. Towards integrated, system-based solutions The challenges across current approaches show the need for solutions that fit existing NHS processes, including laundering and distribution, while also identifying temporary staff, visitors and students. The most effective solutions will improve safety without creating new inefficiencies. A call to action Clear identification in healthcare is not optional. It is a practical safety intervention. When people can immediately see names and roles, communication improves, hierarchy softens, patients feel more reassured and teams are better able to act quickly when it matters most. If the NHS is serious about reducing avoidable harm, improving teamwork and strengthening patient experience, visible identification should be part of the solution. Wearing a detachable badge on a reusable theatre cap sounds very simple but this is a small change that can make a very big difference to the safety of patients. References World Health Organization.
