This month we're heading firmly into the prehospital and community space, looking at how we make decisions when the diagnostics are limited and the system around us is evolving.

We start with a really practical question around traumatic pneumothorax. How good are we, clinically, at spotting the patients who actually need urgent decompression? This paper takes a hard look at the performance of the classic signs we're all taught, and challenges just how much we can rely on them in isolation when it really matters .

From there, we move into one of the biggest ongoing debates in prehospital trauma care: whole blood. The SWiFT trial gives us high-quality randomised data on whether early whole blood transfusion changes outcomes in major haemorrhage. It's a landmark UK study, and the results might not be quite what many were expecting .

Finally, we zoom out slightly and look at how senior decision-making in the community can change patient pathways. This service evaluation explores whether bringing experienced clinicians to the patient can safely reduce conveyance for head injuries, particularly in older and anticoagulated patients, without missing significant pathology.

Decision making sounds like a slightly academic, niche topic… but in reality, it sits underneath every single thing we do in emergency and pre-hospital care. Every patient contact, every test we order, every treatment we start and every one we choose not to – is a decision made in an environment that is time critical, information-light and full of uncertainty.

In this episode we take a step back and look at how we actually make decisions at the front door and on the roadside. We talk about why the importance of the decision really matters, not just whether a diagnosis is possible, but how severe it is, how common it is, and whether finding it will genuinely change what we do for the patient. We explore pre-test probability and prevalence, and why knowing how often a condition really occurs in the group of patients in front of you is one of the most powerful tools in emergency medicine.

We then move into testing. What actually counts as a test? It's not just bloods, scans and ECGs. It's how someone looks, how they move, what hurts when you examine them and how the story fits together. From there, we build into likelihood ratios and Bayesian thinking; how a piece of information should genuinely shift your estimate of risk, rather than just making you feel more or less comfortable.

We also tackle test and treatment thresholds; the idea that there are times when we should stop chasing a diagnosis, and times when the probability is high enough that we should treat without waiting for more tests. Finally, we bring all of this back to real life, with human factors, competing priorities and the reality that sometimes the technically "correct" decision isn't the best decision in that moment.

This one is all about becoming more comfortable with uncertainty and making better decisions because of it.

March's Papers of the Month is here and we've got three absolute crackers to get stuck into.

First up, we head prehospital to explore pseudo-pulseless electrical activity. This review challenges us to rethink how we approach organised electrical activity without a pulse. We discuss the role of POCUS, the concept of treating profound shock rather than "arrest," and what this means for decision-making and management.

Next, we move to cardiac arrest physiology with a systematic review examining intra-arrest diastolic blood pressure and coronary perfusion pressure. We take a look at the proposed thresholds, the heterogeneity in the evidence, and whether haemodynamic-guided resuscitation is ready for prime time.

Finally, we dive into airway nuance with a brand new taxonomy of performance errors in hyperangulated video laryngoscopy. We've covered a very similar paper before on standard geometry VL which was incredibly useful and this looks to do just the same for the alternative technique required with a hyperangulated device. We explore the microskills, the common errors, and what this means for how we train, feedback and improve our emergency intubations.
