969 ACUTE FRAILTY MODEL: A DISTRICT GENERAL HOSPITAL EXPERIENCE OF DELIVERING COMPREHENSIVE GERIATRIC ASSESSMENT

Introduction

Under the NHS Long Term Plan1, every hospital with a Type 1 Emergency Department (ED) has been asked to provide Acute Frailty Services for at least 70 hours a week. We have adopted a liaison model to ensure Comprehensive Geriatric Assessment at the front door. The Frailty Team now includes two Frailty Practitioners, a Specialist Registrar based in ED and the Acute Medical Unit (AMU) with Consultant Physician of the Week support.

Method

The team attend multi-disciplinary meetings in ED and AMU on a daily basis. Frail patients are reviewed and Comprehensive Geriatric Assessments are undertaken together with appropriate signposting. The aim being, to enhance the care of frail patients at the earliest opportunity.

Results

High bed utilisation comes at a cost and a longer length of stay (LOS) is associated with an increased risk of deconditioning. Since introducing incremental changes to our working model, the average LOS of patients on AMU has been reduced from a mean of 1.33 days to 0.82 days. This represents a 38.3% reduction from September 2020 to August 2021. This reduction has been sustained, while 30-day readmission rates have not increased. Feedback has been very positive from all the other teams involved.

Conclusion

Our service has established a more positive working culture to efficiently manage frail patients. The AMU team now feel empowered to make patient-centric decisions regarding patient flow and discharges. Since this data was analysed we have implemented a further change to help enhance the care of frail patients. A list of appropriate patients is emailed to the hospital site team every afternoon to aid getting the right patients into the right beds. The impact of LOS on the frailty wards will then be reviewed following this introduction.

Arts for the Blues - a new creative psychological therapy for depression: a pilot workshop report

INTRODUCTION

Research over the last decade has identified both strengths and limitations in the use of routinely prescribed psychological therapies for depression. More recently, a focus on how creative art therapies and 'arts on prescription' are developing a growing recognition of their potential additional therapeutic mechanisms for depression.

AIM

In an attempt to develop a new therapeutic intervention for depression, this research aligned both the evidence base surrounding the arts on prescription movement, collating these with client-reported helpful factors and preferences for therapeutic interventions.

METHODS

We developed a framework for a new pluralistic 'meta-approach' of therapy for depression, based on; an interdisciplinary thematic synthesis of active ingredients, considered specific features implemented in therapy, and client-reported helpful factors considered to be the broad features or experiences in therapy from both talking therapies and creative approaches. This framework contributed to the development of a pilot workshop entitled Arts for the Blues - A New Creative Psychological Therapy for Depression. An outline of, and evaluation from this workshop is presented in this article. Workshop participants were recruited via a voluntary workshop taking place at a North West Higher Education Institution Arts and Health conference ( N = 15).

RESULTS

The workshop was evaluated using quantitative measures, with results indicating around a 70% overall satisfaction, followed up with qualitative commentary around areas of good practice and areas for development. These included the positive reflection on the application of creative arts and the multimodal nature of the approach, while others reflected on the potential overwhelming nature of utilising multimodal methods for individuals with depression.

CONCLUSION

Overall feedback from the pilot workshop is discussed in relation to prior research, giving credence to the potential for incorporating arts into therapy.

Potential risk factors associated with contact dermatitis, lameness, negative emotional state, and fear of humans in broiler chicken flocks

The objectives of this study were to 1) identify determinants of poor welfare in commercial broiler chicken flocks by studying the associations between selected resource-based measures (RBM, potential risk factors), such as litter quality and dark period, and animal-based welfare indicators (ABM), such as foot pad dermatitis and lameness, and 2) establish the breadth of effect of a risk factor by determining the range of animal welfare indicators associated with each of the risk factors (i.e., the number of ABM related to a specific RBM). Eighty-nine broiler flocks were inspected in 4 European countries (France, Italy, the United Kingdom, and the Netherlands) in a cross-sectional study. The ABM were contact dermatitis (measured using scores of foot-pad dermatitis and hock burn, respectively), lameness (measured as gait score), fear of humans (measured by the avoidance distance test and the touch test), and negative emotional state (measured using qualitative behavior assessment, QBA). In a first step, risk factors were identified by building a multiple linear regression model for each ABM. Litter quality was identified as a risk factor for contact dermatitis. Length of dark period at 3 wk old (DARK3) was a risk factor for the touch test result. DARK3 and flock age were risk factors for lameness, and the number of different stockmen and DARK3 were risk factors for QBA results. Next, the ABM were grouped according to risk factor and counted. Then, in a second step, associations between the ABM were investigated using common factor analysis. The breadth of a risk factor's effect was judged by combining the number (count) of ABM related to this factor and the strength of association between these ABM. Flock age and DARK3 appeared to affect several weakly correlated ABM, thus indicating a broad range of effects. Our findings suggest that manipulation of the predominant risk factors identified in this study (DARK3, litter quality, and slaughter age) could generate improvements in the related ABM and thereby enhance the birds' overall welfare status.

Cefazolin use in patients who report a non-IgE mediated penicillin allergy: a retrospective look at adverse reactions in arthroplasty

BACKGROUND

A large number of patients presenting for total hip and knee arthroplasty report an allergy to penicillin. the reported incidence of cross reactions with cephalosporins in patients with penicillin allergy ranges from 3% to 18%. Perioperative antibiotic prophylaxis practices range from using cephalosporins to substituting clindamycin or vancomycin. the purpose of this study was to determine whether cefazolin can be used safely in the perioperative setting in patients with reported non-IgE mediated reactions to penicillin.

METHODS

We retrospectively reviewed all primary total hip and knee arthroplasty (2012) and revision (278) cases done at a canadian university hospital from 2007 to 2010. We calculated the prevalence of reported penicillin allergy, the specific reaction reported, and the observed reaction rate in penicillin allergic patients given cefazolin.

RESULTS

The prevalence of reported penicillin allergy was 9.9%. there was a wide range of reported reactions, with 25% IgE mediated and 75% non-IgE mediated. Only 27% of patients reporting penicillin allergies were given cefazolin. there were no adverse reactions when non-IgE mediated penicillin allergy patients received cefazolin.

CONCLUSION

surgical patients with reported non-IgE allergic reactions to penicillin have a low chance of adverse reaction to perioperative administration of cefazolin. Only a fraction of surgical patients with reported non-IgE mediated reactions to penicillin receive cefazolin perioperatively.

A simplified liquid chromatography tandem mass spectrometry assay, using on-line solid-phase extraction, for the quantitation of cortisol in saliva and comparison with a routine DELFIA method

Background

We have developed a liquid chromatography tandem mass spectrometry (LC-MS/MS) method for measuring salivary cortisol, which requires only 200 μL sample and no extraction.

Methods

Sample (200 μL) and 25 μL internal standard were added directly to a 96-deep-well plate. Of this, 50 μL was loaded onto a guard cartridge, the cartridge was then washed and the eluate was diverted to waste. The compounds were eluted from the guard cartridge onto the C18 analytical column. Cortisol and deuterated cortisol were monitored using transitions m/z 363.2 > 121.1 and 365.1 > 122.2, respectively.

Results

The method had a lower limit of quantitation of 2 nmol/L. Intra-assay and inter-assay imprecision were better than 9.5%. Comparison with an established dissociation enhanced lanthanide fluorescent immunoassay (DELFIA) gave good agreement for the majority of samples; LC-MS/MS = 1.0065 × DELFIA − 3.7 ( n = 130). The reference range was determined to be 5.8–45.7 nmol/L at 08:00 h and <6.4 nmol/L at 23:00 h ( n = 44).

Conclusions

We have developed a simple, robust assay to measure salivary cortisol using on-line solid-phase extraction to reduce sample clean-up requirements.

End-plate gamma- and epsilon-subunit mRNA levels in AChR deficiency syndrome due to epsilon-subunit null mutations

Acetylcholine receptor (AChR) deficiency is the most common of the congenital myasthenic syndromes (CMS). Typically, the number of AChRs, measured by alpha-bungarotoxin binding, is reduced to 10-30% of normal levels, the miniature end-plate potentials are correspondingly reduced, and there are morphological changes at the motor end-plates. The majority of these syndromes are due to either missense or frameshift mutations within the gene encoding the adult-specific epsilon-subunit. These are often null mutations, but some mutant epsilon-subunits can be incorporated, at low levels, into functional AChRs in transfected cell lines. It is not clear, therefore, whether upregulation of the mutant epsilon-subunit mRNA could generate sufficient AChR to support neuromuscular transmission, albeit at a reduced level. Conversely, it might be that the mutant epsilon-subunit transcripts are subject to mRNA surveillance and 'nonsense-mediated' loss, leading to reduced epsilon-subunit mRNA expression. In either case, it is thought that neuromuscular transmission may be provided partly or entirely by incorporation of the foetal-specific gamma-subunit into end-plate AChR. gamma-Subunit mRNA is expressed at low levels in normal human muscle, but might be upregulated in CMS. The study of mRNA levels for AChR subunits should improve our understanding of genotype-phenotype relationships in CMS. Here we have defined homozygous epsilon-subunit mutations in four unrelated families with AChR deficiency and studied the steady-state levels of mRNA for AChR subunits at the motor end-plates by in situ hybridization. Although we demonstrated that each mutation would lead to almost complete absence of surface adult AChR expression, we detected similar robust expression of alpha- and epsilon-subunit mRNAs at end-plates of patient and control muscles, suggesting that mRNA transcripts for the epsilon-subunit are neither upregulated nor degraded preferentially. Interestingly, we were unable to detect any increase in gamma-subunit mRNA expression at CMS end-plates. Transgenic mice lacking the epsilon-subunit die 2-3 months after birth, suggesting that alpha(2)betadelta(2) pentamers cannot sustain neuromuscular transmission. Therefore, we tentatively conclude that the persistent low level expression of the gamma-subunit, which is present in normal human muscles as well as in AChR deficiency syndromes, is sufficient to enable patients with epsilon-subunit null alleles to survive.
