Neurocysticercosis presenting as a ‘Stroke Mimic’

A 62 year old Nepalese gentleman presented with left sided weakness and sensory loss. Initial brain CT scanning was suggestive of acute infarction but a subsequent MRI scan showed cysts with oedema. Cysticercosis serology was positive and a diagnosis of neurocysticercosis was made. The patient made almost a complete recovery after treatment with albendazole, praziquantel and steroids. Neurocysticercosis should be considered in the differential diagnosis when patients originating from endemic areas present with focal neurological deficit.

An Acute Severe Headache

A previously fit and healthy 57 year old gentleman presented to hospital 2 weeks after a previous admission with acute severe headache. At the time of his previous admission the patient had reported that the headache was preceded by an unprovoked sharp pain in his back which had quickly resolved. The headache developed a few hours later and was noted to be markedly worsened by any attempt to sit upright, accompanied by intense nausea, and relieved by lying flat.

Unscheduled care admissions at end-of-life – what are the patient characteristics?

Unscheduled acute hospital admissions and subsequent deaths in hospitals of patients considered palliative are increasing, despite many patients’ preference to die at home. A large proportion of these patients are admitted via acute medical units or emergency departments. The integration of primary and secondary care within Wales should enhance the delivery of end-of-life care at home but unscheduled admission for patients with palliative care needs remains prevalent. The aim of our study was to explore the characteristics amongst patients who die shortly after unscheduled hospital admission. A retrospective, observational study was conducted in all unscheduled admissions at end-of-life at a single health board in South Wales, UK over a period of one month. The result showed that 47% of patients who died within 48hrs of unscheduled admission are considered to be palliative. The majority of these patients were admitted via 999 ambulances and out of normal working hours (65%). They were elderly (median age 80) and had a poor performance status (78%). Over 1/3 (39%) were admitted from a nursing or residential home. Less than a quarter (22%) had an advance care plan in place.

Repeat duplex ultrasound scanning in suspected Deep Vein Thrombosis (DVT): putting the onus back on the referring clinician

Duplex scanning is utilised by many departments in the investigation of suspected Deep Vein Thrombosis (DVT). NICE Guideline CG144 recommended repeat scanning for patients in whom the initial Wells score was ‘likely’ in the presence of a raised D-Dimer, following a normal first scan. Following implementation of this recommendation in our department there was a dramatic rise in the number of repeat scans being undertaken, all of which were negative for DVT. Introduction of an electronic message to the report, placing the onus back on the referring clinician to arrange repeat scan if deemed appropriate resulted in a fall in the number of scans being undertaken without impacting on patient outcome.

Investigating for pulmonary embolism in pregnancy: Five year retrospective review of referrals to the acute medical unit of a large teaching hospital

This was a retrospective review of five years’ data relating to patients referred to the Acute Medical Unit (AMU) of a large teaching hospital with suspected Pulmonary Embolism (PE) during pregnancy or 6 weeks postpartum. During this period, 210 patients in this group underwent half-dose perfusion scanning as investigation for possible PE and were managed via our ambulatory pathway. Pulmonary embolism was diagnosed in 5.2% of patients compared to 18% of non-pregnant patients identified in a previous audit. Half-dose Q scanning enabled exclusion of PE in almost 90% of patients without the need for further imaging. A new local pathway for the investigation and management of PE during pregnancy has now been developed.

Tracking the take – Using patient flow data to improve AMU performance and safety

Abstract

Aims: To create a system to co-ordinate the medical take, bed management and track patient flow.
To use the system to continuously audit against Society for Acute Medicine Quality Indicators.
To use the data to model patient flow and optimize working patterns to improve waiting times.

Method: An online whiteboard and underlying database system were designed, tested and implemented.
Data from this system were used to audit against SAM Quality Indicators and then analysed to optimise both trainee and consultant working patterns.

Results: The online whiteboard proved effective and popular as a working tool.
Data collection improved using the electronic system.
Optimising junior doctor working patterns to match demand led to a reduction of average waiting time to see a doctor from 190 minutes to 71 minutes (p < 0.0001), and a reduction in the proportion of patients waiting over 4 hours from 40% to 10% (p < 0.0001). Optimising consultant working patterns did not produced significant changes in waiting times. Conclusions: The online whiteboard improved day-to-day working and data collection, when compared to the previous paper-based system. Better data facilitated analysis of working patterns leading to a significant improvement in patient waiting times.

Editorial Volume 15 Issue 2

Hospital mortality has been a hot topic in the medical and popular Press over recent years. Many readers will recall ‘scandals’ around hospitals whose mortality rates appeared higher than that which would be expected. The so-called ‘weekend effect’ whereby patients admitted to hospital between Friday and Monday appear more likely to die during their hospital stay has been regularly quoted in Parliament by the Secretary of State as justification for the Government’s manifesto pledge to create a ‘7 day NHS’. A number of recent publications have illustrated the complexity of this statistic, which – at least in part – is likely to reflect illness severity as much as organizational factors. The paper by Emma Mason in this edition further supports the concept that hospital mortality statistics may be hard to influence through structural or staffing changes. Those working in the acute medicine setting will not be surprised to read that almost half of those patients who die within 48 hours of arrival in hospital had solely palliative care needs at the time of admission. Many of these patients were elderly, frail and resident in a care home environment, but many also had undergone previous admissions within the months leading up to their death; the authors comment that this could have provided an opportunity to discuss end of life care plans, potentially enabling their final admission to hospital to have been avoided. Preventing ‘avoidable’ deaths in hospital from conditions such as sepsis and acute pulmonary embolism is a key component of the job of an acute physician. However, even when death in unavoidable we must do what we can to ensure patients die in the environment of their choice. Reducing deaths in hospital should not simply focus on those whose death can be prevented.

Although mortality statistics may be misleading when interpreted in isolation, good quality data can be a powerful tool to influence changes in the acute medicine setting. By the time this edition is published, the 2016 Society for Acute Medicine Benchmarking Audit (SAMBA16) will already have take n place; previous years’ data were published in this journal and we hope to see a continued rise in the numbers of participating units this year. Tom Brougham and colleagues from Bristol have illustrated how an electronic system for data collection on their AMU enabled reorganization of their junior doctor rota, reducing waiting time for patients. Their data illustrate the problem which will be familiar to many acute physicians, whereby the surge in afternoon arrivals on the AMU often coincides with shift changeovers and reductions in junior doctor and other numbers. Matching staffing to workload can have significant benefits for patient care and may enable a reduced strain on the night shift team if patients are seen in a more timely fashion. Whether this can be linked to improved patient outcomes in the future will be interesting.

Finally, I would like to welcome one more addition to the editorial board. Dr Nick Murch is an acute physician in the Royal Free hospital, with an interest in medical education and simulation skills training. With an increasing number of acute medicine trainees undertaking medical education as their specialist skill, I am keen to develop the training and education section of the journal over the coming years, and look forward to Nick’s input in this regard. We will continue to welcome submissions of research relating to acute medicine education and training, which we will consider for future publication in this section of the journal.

An Acute Severe Headache

Discussion

Severe headaches are a frequent presentation to the Emergency Department, accounting for around 1% of presentations. Of these, 13-16% will have a sinister underlying pathology but accurate diagnosis of headaches on the medical take remain difficult for non-specialists. A retrospective study from the UK found that, of those presenting to Emergency Department with sudden onset severe headaches, only 60% were given a specific headache diagnosis, with one third of these given their diagnoses despite an inadequate history.

Providing a navigable route for acute medicine nurses to advance their practice: a framework of ascending levels of practice

This article conveys concerns raised by delegates at the International SAM Conference (Manchester, 2015) regarding how to advance nursing practice in acute medicine. It endeavours to capture the essence of ‘how to advance practice’ and ‘how to integrate advanced practice’ within the workforce structures of an acute medicine unit (AMU). It addresses the production of tacit knowledge and the recognition and integration of this to developing the nursing workforce. The current context of NHS efficiencies and recruitment issues emphasize the value of retaining tacit knowledge. Uniquely, this article offers an early conceptual framework through which levels of advancement and potential transition points to advance nursing practice in acute medicine are articulated. Determining how to advance requires identification of prior accomplishments such as, tacit knowledge, experiential learning, CPD, specialist courses and management experience. This requires nurses to make judicious decisions to advance their practice and the distinction between ‘amassing experience’ and ‘career progression’. It aims to stimulate thinking around the practicalities of advancement, the value of tacit knowledge and potential realization through the framework trajectory.
