Outdoor incidents rarely happen in convenient places. 

 

You may be dealing with poor light, cold weather, uneven ground, and a group who are looking to you for direction. 

 

The scene is safe, your group is sorted but in these moments, structure matters. 

 

That is where ABCDE comes in — a simple, structured approach to clinically assess, identify and treat life-threatening problems. 

 

It is widely used in emergency medicine and trauma care because it prioritises the problems most likely to kill a casualty first. 

Research shows the ABCDE approach improves recognition of life-threatening conditions and helps teams prioritise treatment effectively (Thim et al., 2012). 

 

For outdoor leaders, it provides something just as valuable: 

 

A clear thinking process when situations become chaotic. 

Standing on a winter hillside waiting for rescue. 

 

The call had been made early. 

Good decisions taken. 

Still — it's going to be hours. 

 

That’s the reality in the UK. Mountain Rescue teams are voluntary, highly skilled, and exceptionally committed. But they must mobilise, travel and access you. In winter terrain, two to four hours is common. 

 

If you lead others outdoors, that delay matters. 

 

Because once the immediate problem is addressed, the environment becomes the main threat. 

Outdoor first aid rarely happens in ideal conditions. 

 

It happens with cold hands. 

With waterproofs flapping. 

With a headtorch beam bouncing off rain, sleet, or spindrift. 

 

Yet many people still practise first aid bare-handed, in daylight, on a warm floor. 

 

That gap matters. 

 

This article looks at how gloves, clothing layers, and darkness affect casualty care — and what you can do to adapt your first aid so it still works when conditions are stacked against you. 

A broken femur (thigh bone) is one of the most serious injuries you can face outdoors. It’s not just a painful fracture – it’s a life-threatening emergency that can cause massive internal bleeding and shock. It can kill you, the casualty needs to be in hospital ASAP, with safe, expedient evacuation. Not an orange survival bag, six rocks, a broom handle and a wish and a prayer. 

 

So what should a first aider actually do? Do you call 999 and wait, or do you try and splint the leg with sticks and bandages? 

 

I can remember early in my career, outdoor courses making improvised traction splints, it was a laugh and we thought it was cool. Three decades down the line and having attended serious fractures of the pelvis and femur, it is not a laughing matter. 

 

It is not as easy in real life as it is in a classroom, it is incredible painful and the risks are high if you cock it up. Add to that, we will have to take everything off to put proper splints in place. More movement, more pain, more time wasted. 

 

Let’s break it down. 

 

 

You’re halfway through a group walk when someone missteps on a loose rock. They go down hard, and you hear those classic words: 

 

“I think I’ve just twisted it. I’ll walk it off.” 

 

As an EMT, I’ve learned never to underestimate soft tissue injuries. Out here, even a “minor sprain” can turn into a major problem if not managed properly. 

 

You’re an hour into a coastal hike. It’s roasting. One of your group sits down suddenly, looking pale, sweaty, and just not quite right. “I’m fine,” they say. But are they? 

 

As an EMT, I’ve treated more than a few heat-related emergencies — on city streets, at music festivals, and the uplands of the UK where help is hours away. The key to managing heat illness is catching it early, acting fast, and knowing when ‘just hot’ becomes dangerous.
