Based at the University Hospitals of Leicester, we serve the educational needs of healthcare practitioners in Acute & Emergency Medicine across the East Midlands, UK
The presentation of a patient with a severe headache to the Emergency Department is a common one. Whilst most are benign in nature, a small percentage represent potentially devastating aetiologies.
The task of the ED doctor is to differentiate between the two.
The doctor must be guided by the knowledge that:
Extensive investigation of all cases will result in many false positive
Failure to identify headaches due to serious aetiologies can result in fatal, or irreversible, outcomes
The International Headache Society classifies headaches into primary and secondary groupings.
Primary causes are sometimes referred to as benign. However, this term is misleading as they are associated with considerable morbidity and indirect mortality.
Acute, severe headache is a common symptom of patients presenting to the Emergency Department. In 90% of cases, the cause will be one of the primary headache syndromes.
Delirium (acute confusional state) is common in hospital medicine. In the elderly, the prevalence of delirium ranges from 11%-42% (Siddiqui et al., 2006).
Patients with delirium have:
Increased length of hospital stay
Higher risk of complications in both medical and surgical settings
Higher mortality, both in hospital and up to 6 months following discharge (APA, 1999)
It is estimated that one-third of cases are preventable (Inouye et al., 1999). However, the detection and documentation of delirium by Emergency Physicians is poor, with reported sensitivity rates as low as 35% (Hustey and Meldon, 2002).
It is an essential skill for Emergency Physicians to be able to identify, rationally assess and implement effective initial treatment strategies in confused elderly patients.
Describe a pragmatic, focussed method of eliciting the relevant history of an acute headache
List an appropriate differential diagnosis for acute headaches
Describe a logical method to rule in, or rule out, the principle causes of acute headaches
Demonstrate when primary headache syndromes require further investigation
List an appropriate differential diagnosis for acute secondary headache
Describe a logical method to rule in, or rule out, the principle causes of acute secondary headache
Describe characteristic findings on lumbar puncture and CT of the more important differential diagnoses of acute secondary headache
Summarise the morbidity and mortality associated with acute confusion in the elderly
Outline, with examples, common presentations and precipitants
Create and justify a structured, pragmatic approach to the investigation of the acutely-confused elderly patient
Explain how to implement appropriate treatment strategies, after considering a differential diagnosis
Highlight the pitfalls that may be encountered in the management of the acutely-confused elderly patient
Formulate appropriate differential diagnoses and management strategies for patients presenting with headaches.
Revise lumbar puncture indication and techniques in the Emergency Department and be able to interpret basic CSF results.
Appropriately investigate and formulate management plans in acute delirium and confusion, especially in older patients.
Complete the following before the face-to-face session:
Duration: 20 mins
Read the following document from MPS casebooks. This is a very good document based on case series of misdiagnosed headaches with dire consequences. Well worth a read. Pages 8-14 only.
Duration: 14 mins
Listen to this RCEMFoamed podcast by Leicester's Dr Acheson and Dr Banerjee. It covers acute confusion in the emergency department.
Duration: 30 mins
This is summary from the IPE session held in the department serves as a good introduction to the subject and how we can identify patients with delirium. It also covers why it is important that we identify patients with delirium in the ED. You can listen to the audio from the session as well as review the slides, don't forget to also check out the infographic.
For another quick summary we also have Lightning Learning.
You should familiarise yourself with relevant Local Guidelines, for East Midlands Trainees we are aiming to host these on the website shortly (although this may password protected).
In the meantime please review your local guidelines relevant to chest pain.
We have written a series of interactive cases (wikis) with short answer questions to be answered by trainees prior to the face to face teaching sessions. Currently this is only available to East Midlands Trainees.
Answer one or two questions before attending the face-to-face teaching session. Add comments to answers already given if you think it's appropriate. We will also provide tutor comments. If you find good resources that answer a question why not include links in your comment.
Part of the face-to-face teaching will be spent discussing the case(s) below:
Here are some extra resources to review if you want more information:
As part of their "Best Case Ever" series they look at a case from America of a repeat attender with a headache. If you haven't heard any of these before it is worth going to their website and having a look - several of these appear in other modules.
"Welcome to the Headache: The Journal of Head and Face Pain podcast channel. Headache is the official publication of the American Headache Society. Headache publishes original, peer-reviewed work in all areas of head and face pain. This channel features audio files and occasional videos intended for patients and practitioners alike, related to papers published in the journal."
Each week in the UK, around ten children or teenagers are diagnosed with a brain tumour in the UK. The time taken from a child’s first symptoms to diagnosis of a brain tumour for half of the children to be diagnosed is currently 12-13 weeks (median) in the UK.
The aim of the HeadSmart campaign is to reduce the time it takes to diagnose children and young people with brain tumours in the UK by education.
