Can we predict Acute Medical readmissions using the BOOST tool? A retrospective case note review

Abstract

Background: Readmissions within 30-days of hospital discharge are a problem. The aim was to determine if the Better Outcomes for Older Adults through Safe Transitions (BOOST) risk assessment tool was applicable within the UK.

Methods: Patients over 65 readmitted were identified retrospectively via a casenote review. BOOST assessment was applied with 1 point for each risk factor.

Results: 324 patients were readmitted (mean age 77 years) with a median of 7 days between discharge and readmission. The median BOOST score was 3 (IQR 2-4) with polypharmacy evident in 88% and prior hospitalisation in 70%. The tool correctly predicted 90% of readmissions using two or more risk factors and 99.1% if one risk factor was included.

Conclusion: The BOOST assessment tool appears appropriate in predicting readmissions however further analysis is required to determine its precision.

Variation in Acute Medicine Units: Measuring it, understanding it, and reducing it

Abstract

Although there are national recommendations on the function of Acute Medicine Units (AMUs), there is no single agreed best model of care. Additionally, robust data is not always available to determine whether system changes have resulted in improvement. We designed an Excel file to interface with the hospital patient management system to provide real-time data on a number of metrics including AMU length of stay (AMULOS), mortality and readmissions. This demonstrated that improving consultant continuity of care was associated with a reduction in AMULOS and reduced variation in AMULOS. Additionally, the Excel file provides timely access to consultant and individual patient-level data. These data are clinically owned, and critical for both unit governance and quality improvement work. We would encourage all AMUs to develop a similar dataset to allow standardised comparisons between units, and better understanding of the association between models of care and patient outcomes.

Editorial Volume 15 Issue 3

Acute Medicine is full of ‘C-words’ – the Nursing and Midwifery Council’s ‘Six Cs’ (Care, Compassion, Competence, Commitment, Courage and Competence) are as relevant on the AMU as anywhere else in the Health Service; acute physicians would probably also include co-ordination, collaboration and crisis management, as winter looms before us. Dan Beckett’s paper from Forth Valley in Scotland, suggests another word that should be added to the list. As we strive to design sustainable rotas which span 7 days and comply with European work-time directives it is understandable that continuity often falls by the wayside, particularly in smaller Units. The transition from the acute medicine team to an in-patient specialist ward will usually, and appropriately, require hand-over of care. However, as described in this paper, patients who remain within the AMU may find that they see a different consultant each day. Moving to a model whereby patients in the AMU remained under the care of the admitting consultant was shown to shorten their AMU length of stay, facilitating transfer to the appropriate in-patient team, although not increasing the proportion of patients discharged directly from the unit. The authors proposed that this latter finding related to changes in the skill mix of the consultant team covering the AMU, demonstrating the complexity of the challenges we face. It would have been interesting to study the impact on patient satisfaction – as well as consultant job satisfaction – from this new model; my own, purely anecdotal data, suggests both may be considerably improved.

This month’s case report selection illustrates some interesting clinical conundrums. Lower limb cellulitis is a common reason for presentation to the acute medical, or ambulatory care unit; however, when the rash or erythema is bilateral, there is often an alternative diagnosis. In the case described by Cranga and colleagues, antibiotics turned out be the cause (rather than the solution) to the problem. Early liaison with the dermatology team enabled the diagnosis of acute generalized erythematous pustulosis to be made, and resolution of the condition followed discontinuation of antibiotics. The authors include a useful table to support clinicians in making this (albeit rare) diagnosis. Emily McNicholas reminds us of the importance of a collateral history – it is not hard to see how a patient with fever, confusion and incontinence might be labelled as having a urinary tract infection; the retrospective story of a cocktail stick in the throat prior to onset of the symptoms might have pointed to the correct diagnosis is this had been obtained at the time of admission. This case also shows the dangers of separation of Emergency Department notes from those of hospital in-patients, even within the same organization – a problem which will be familiar to many UK readers of this journal.

Patients with frailty represent a significant proportion of admissions to the acute medical take and often provide considerable management challenges. Natalie Offord and colleagues from the British Geriatric Society have described the development of the Frailsafe collaborative which
clearly provides a major step forward. At the other end of the age spectrum, adolescents and young adults (AYAs) may represent a different kind of challenge for the acute medicine team. Some of the key messages from the recent Royal College of Physicians’ Acute Care Toolkit for AYAs are summarized in the article on p157. Anyone who is involved in managing this group of patients is recommended to read this article, and please look out for the link to a survey about this at the end of the article.

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.
