Addressing moral injury in the military

Moral injury is a relatively new, but increasingly studied, construct in the field of mental health, particularly in relation to current and ex-serving military personnel. Moral injury refers to the enduring psychosocial, spiritual or ethical harms that can result from exposure to high-stakes events that strongly clash with one's moral beliefs. There is a pressing need for further research to advance understanding of the nature of moral injury; its relationship to mental disorders such as posttraumatic stress disorder and depression; triggering events and underpinning mechanisms; and prevalence, prevention and treatment. In the meantime, military leaders have an immediate need for guidance on how moral injury should be addressed and, where possible, prevented. Such guidance should be theoretically sound, evidence-informed and ethically responsible. Further, the implementation of any practice change based on the guidance should contribute to the advancement of science through robust evaluation. This paper draws together current research on moral injury, best-practice approaches in the adjacent field of psychological resilience, and principles of effective implementation and evaluation. This research is combined with the military and veteran mental health expertise of the authors to provide guidance on the design, implementation and evaluation of moral injury interventions in the military. The paper discusses relevant training in military ethical practice, as well as the key roles leaders have in creating cohesive teams and having frank discussions about the moral and ethical challenges that military personnel face.

Bovine congenital defects recorded by veterinary practitioners

A mobile phone app was used by 59 veterinary practitioners to collect case histories and images of 191 cattle with congenital defects distributed nationally over a 3-year period. The majority of cases were recorded during the spring calving season (57.6%) in pluriparous dairy dams. The majority of calves were recorded at birth or within the first week (66.5%) in singletons born at full-term. On the majority of farms (75.9%), this was the only congenitally deformed bovine recorded up to that point in the year and on the majority of farms, there were no congenitally deformed cattle recorded in the previous 5 years. The majority of congenital defects (83.5%) were recorded in the musculoskeletal or digestive systems. The three most commonly recorded individual defects were intestinal atresia (24.1%), schistosomus reflexus (20.4%) and ankylosis (6.8%); multiple defects were recorded in 13.1% of cases. These findings highlight the relatively high prevalence of intestinal atresia and schistosomus reflexus in calves attended by veterinary practitioners, which warrants implementation of preventive measures. The project highlights the potential benefits of veterinary-practitioner apps to detect changing trends in endemic, or the emergence of novel, congenital or other conditions.

Investigating the impact of non-gated thoracic CT prior to CTCA to reduce layered testing

AIM

To determine the proportion of computed tomography (CT) coronary angiography (CTCA) referrals with coronary artery calcification (CAC) evident on previous non-cardiac CT imaging and how this impacted the diagnostic yield for CTCA, the requirement for additional diagnostic testing, and the associated costs to confirm or refute obstructive coronary artery disease (CAD).

MATERIALS AND METHODS

A retrospective review of CTCA examinations was undertaken between 01/05/2018 and 31/05/2020 in which the examinations were cross referenced for previous non-gated thoracic CT at Royal United Hospitals Bath. Major epicardial vessel CAC on baseline CT was re-evaluated by published semi-quantitative methods, giving a per-patient CAC score (mild = 1-3, moderate = 4-6, severe >6). Subsequent incomplete CTCA diagnostic yield, further testing, and cost implications were examined.

RESULTS

Of the 2140 CTCA examinations identified, 13% (280/2140) had a preceding non-gated thoracic CT (53% female, age 63 ± 11 years). The incomplete diagnostic rate increased with CAC grade, mild 32%, (RR 12; 95% CI 4-40), moderate 64% (RR 25; 95% CI 8-80), severe 75%, (RR 29; 95% CI 9-94). Additional diagnostic testing occurred in 4% for the mild CAC category, and 14% and 42% for moderate and severe, respectively. When severe CAC was identified on a non-gated thoracic CT a cost saving of £171/patient (dobutamine stress echo [DSE]) and £61/patient (myocardial perfusion scintigraphy [MPS]) was established with a direct to functional testing pathway.

CONCLUSIONS

In patients referred for CTCA where severe CAC was identified on a preceding non-gated thoracic CT a direct to functional testing altered management in 42% of cases and was cost-effective.

Post-mortem computed tomography in the investigation of conflict and terrorist related deaths: UK military experience of developing a multidisciplinary service

This paper discusses the introduction, development and utility of post-mortem imaging relating specifically to conflict-related and terrorist-related deaths and considers the use of computed tomography (CT) in the investigations. We demonstrate how a multi-disciplinary approach involving direct communication between forensic pathologist and radiologist can maximise evidential yield, reduce the need for unnecessary dissection and further our understanding of such injuries. This summarises our shared experience of hundreds of cases, each having been individually discussed and reviewed, and has helped shape our understanding of conflict injury as well as contributing to the development of mitigation strategies and adaptations to protective equipment. A series of clinical cases are presented to demonstrate some of the strengths and weaknesses of the process.

Associations between sleep difficulties and health outcomes in treatment-seeking veterans

BACKGROUND

Sleep disturbance in UK Armed Forces personnel appears to be frequent due to factors such as hostile sleeping environments and can persist even once they have transitioned into civilian life. Despite this, there is currently very limited literature surrounding the prevalence and associated factors of insomnia disorder among UK veterans.

AIMS

This study aimed to expand knowledge of the prevalence and associated demographic, military, health and functional outcomes with probable insomnia disorder within a clinical sample of veterans.

METHODS

Treatment-seeking veterans from a national UK mental health charity were invited to complete a questionnaire including socio-demographic, military, health and well-being questions.

RESULTS

Of the sample, 489 (43%) completed the questionnaire. Seventy per cent of the sample reported having probable insomnia disorder. Having probable insomnia disorder was significantly associated with being younger and having physical health problems. Moreover, unadjusted models found associations between probable insomnia disorder and common mental health difficulties, obsessive-compulsive disorder and complex post-traumatic stress disorder.

CONCLUSIONS

The results suggest that many UK veterans with physical and mental health difficulties experience co-morbid insomnia disorder. Therefore, it is important that clinical services are aware of this prevalence and use targeted interventions to reduce the frequency of insomnia disorder in this population.

Military families: the impacts of having a first child during service on military mothers

INTRODUCTION

The rights, roles and responsibilities of servicewomen in the UK Armed Forces has changed dramatically over time. Previously, service personnel were automatically discharged from the military if they became pregnant. As the percentage of servicewomen in the UK Armed Forces increases, having children during service is becoming more common and maternity policies are now in place. Having children during military service can impact on the health and well-being of servicewomen, including a greater risk of illness when returning to work.

METHODS

A cross-sectional, self-report survey was used for data collection. The response rate was approximately 45%. Female Army veterans were recruited via a female military association. The survey collected data on parental status, the timing of their first child (during or after service), and several current mental and physical health and well-being outcomes.

RESULTS

Of the 750 female Army veterans who completed the survey, 406 reported having children. Of those with children, 14.5% had their first child during service compared with 85.5% after service. The most frequently endorsed health outcomes were low social support, loneliness and common mental health difficulties. Participants who had their first child during military service were more likely to have left the service non-voluntarily.

CONCLUSIONS

This study provided insight into the impacts of having a first child during military service on servicewomen. Overall, female Army veterans who had their first child during service had poorer outcomes, including leaving service non-voluntarily. However, none of the health or well-being outcomes remained significant after adjusting the results. This study explored a widely under researched population and field of research. Future research should seek to expand on our findings and continue to explore the impacts of having a first child during military service for military mothers.

Adversity during military service: the impact of military sexual trauma, emotional bullying and physical assault on the mental health and well-being of women veterans

INTRODUCTION

Despite making up about 11% of the UK military, there remains limited investigation on the impact of adversity women experience during their service in the UK military. Military adversity can result in a range of well-being difficulties that may persist following transition out of military. The present study therefore examined the prevalence and correlates of different types of military adversity (defined as sexual harassment, sexual assault, emotional bullying and physical assault) within a community sample of UK women veterans.

METHODS

Participants were recruited from a UK charity supporting women veterans. 750 women veterans completed an online survey collecting information on sociodemographic and military factors, military adversity, as well as mental health and well-being difficulties. Associations between variables were explored using multivariate logistic regressions.

RESULTS

The findings indicate a high prevalence of military adversity (22.5% sexual harassment, 5.1% sexual assault, 22.7% emotional bullying and 3.3% physical assault). Younger women, those who held an officer rank during service and those who reported having a combat or combat support role during service were most at risk of military adversity. All types of adversity were significantly associated with probable post-traumatic stress disorder. Sexual harassment was additionally significantly associated with physical somatisation; sexual assault with alcohol difficulties; and emotional bullying with common mental health difficulties, low social support and loneliness.

CONCLUSIONS

This study indicates that UK women veterans are at risk of a range of adverse experiences during military service and provides evidence of the impact of such adversities on mental health and well-being. Further research is required to better understand these relationships.

A patient perspective on applying intermittent fasting in gynecologic cancer

OBJECTIVE

Researchers sought patient feedback on a proposed randomized controlled trial (RCT) in which gynecological cancer patients would modify their diets with intermittent fasting to gain insight into patients' perspectives, receptivity, and potential obstacles. A convenience sample of 47 patients who met the inclusion criteria of the proposed RCT provided their feedback on the feasibility and protocols of the RCT using a multi-method approach consisting of focus groups (n = 8 patients) and surveys (n = 36 patients).

RESULTS

Patients were generally receptive to the concept of intermittent fasting, and many expressed an interest in attempting it themselves. Patients agreed that the study design was feasible in terms of study assessments, clinic visits, and biospecimen collection. Feedback on what could facilitate adherence included convenient appointment scheduling times and the availability of the research team to answer questions. Regarding recruitment, patients offered suggestions for study advertisements, with the majority concurring that a medical professional approaching them would increase their likelihood of participation.

Prolonged neuraxial block following spinal anaesthesia in a patient with carnitine palmitoyl transferase II deficiency undergoing caesarean section

Carnitine palmitoyl transferase II (CPT II) deficiency is a rare disorder of fatty acid metabolism in cell mitochondria. There is limited information about the disease process and complications of anaesthesia, particularly in the obstetric population. Due to the increased risks of general anaesthesia in patients with CPT II deficiency, neuraxial anaesthesia is the preferred method of anaesthesia. We describe a patient with CPT II deficiency who had spinal anaesthesia for caesarean section. Subsequently, the patient had prolonged neuraxial blockade, a previously undescribed complication in a patient with CPT II deficiency.

Veterans' experiences of moral injury, treatment and recommendations for future support

INTRODUCTION

Moral injury (MI) significantly impacts the lives of many UK military veterans however, there is a lack of manualised treatment to address the needs of this population. To develop future treatments that are acceptable and well tolerated, veterans should be consulted on their experiences of existing psychological treatments and suggestions for future treatments.

METHODS

10 UK military veterans were interviewed about their experiences of receiving treatment for psychological difficulties after MI, and beliefs about core components of future treatments. Thematic analysis of these interviews were conducted.

RESULTS

2 superordinate themes were identified: experiences of previous mental health treatment and perceptions of the proposed treatments. Reflections on cognitive behavioural therapy were mixed, with some describing that it did not ameliorate their guilt or shame. In future treatments, focusing on values, using written letters and including therapy sessions with close companions were considered beneficial. Veterans reported that a strong rapport with therapist was key for MI treatment.

CONCLUSION

Findings provide a useful account of how current post-trauma treatments may be experienced by patients with MI. Although limited by sample size, the results highlight therapeutic approaches that may be helpful in future and provide important considerations for therapists treating MI.

Using statistical techniques to understand the unique needs of military personnel experiencing mental health difficulties: moving away from assuming patient homogeneity to understanding heterogeneity

Gold standard treatments for military personnel seeking support for mental health difficulties are often standardised and manualised to ensure high levels of treatment fidelity. While manualised treatments are preferable to less evidence-based idiosyncratic approaches, they may not fully account for the differences in symptom profiles present in patients with the same psychological diagnosis. Indeed, recent findings have highlighted that a significant proportion of individuals do not benefit from the 'gold standard' treatments. This brief report discusses the utility of statistical techniques, specifically latent profile analysis and network analysis, to support the transition to more evidence-based idiosyncratic, personalised care for clinical military, and general, populations. Further incorporation of such analysis methods may support arriving at a framework to support the personalisation of care in terms of the selection and adaption of evidence-based approach treatments based on individual clinical need.

Personalised digital technology for mental health in the armed forces: the potential, the hype and the dangers

The COVID-19 pandemic has resulted in a digital technology revolution which included widespread use in remote healthcare settings, remote working and use of technology to support friends and family to stay in touch. The armed forces have also increased its use of digital technology, but not at the same rate, and it is important that they do not fall behind in the revolution. One area where digital technology could be helpful is the treatment and management of mental health conditions. In a civilian setting, digital technology adoption has been found to be acceptable and feasible yet there is little use in the armed forces. In this personal view, we explore the potential use of personalised digital technology for mental health, the hype surrounding it and the dangers.This paper forms part of the special issue of BMJ Military Health dedicated to personalised digital technology for mental health in the armed forces.

"Healing Can Be a Very Jagged Line": Reflections on Life as a COVID-19 Long Hauler

"Long COVID" - a term referring to COVID-19-associated symptoms and conditions (ie, sequelae) that remain or emerge after resolution of a SARS-CoV-2 infection - is a multifaceted condition about which little is known. As part of formalized patient-engaged research at a large Midwestern health system, patient stakeholders with long COVID (N=5) wrote stories based on their lived experience, as this was their preferred format for detailing their experience with the condition. These patient stakeholders reviewed one another's stories, identified relevant quotes, and provided opportunities for elaboration. Independently, a trained researcher extracted quotes from the stories, identified themes, and wove the quotes together to share the independent, yet similar, stories. Emergent themes were that of uncertainty about the symptomatology of long COVID and its effects on patients' mental health, physical functioning, family unit, self-identity, and future outlook. Further patient-engaged research on understanding the lived experience of long COVID may serve to advance knowledge and treatment. Health care providers caring for those with long COVID can benefit from listening and validating the stories of individuals suffering from this condition.

Effectiveness of treatments for symptoms of post-trauma related guilt, shame and anger in military and civilian populations: a systematic review

INTRODUCTION

Individuals who have been exposed to a traumatic event can develop profound feelings of guilt, shame and anger. Yet, studies of treatments for post-traumatic stress disorder (PTSD) have largely investigated changes in PTSD symptoms relating to a sense of ongoing fear or threat and the effectiveness of such treatments for post-trauma related guilt, shame or anger symptom reduction is comparatively not well understood.

METHODS

This review systematically examined the effectiveness of existing treatment approaches for three symptoms associated with exposure to traumatic events: guilt, shame and anger. Studies included had to be published after 2010 with a sample size of n=50 or greater to ensure stable treatment outcome estimates.

RESULTS

15 studies were included, consisting of both civilian and (ex-) military population samples exposed to a wide range of traumatic events (eg, combat-related, sexual abuse). Findings indicated a moderate strength of evidence that both cognitive-based and exposure-based treatments are similarly effective in reducing symptoms. Cognitive-based treatments were found to effectively reduce post-trauma related guilt and anger, while exposure-based treatments appeared effective for post-trauma related guilt, shame and anger.

CONCLUSIONS

The findings suggest the importance of confronting and discussing the traumatic event during therapy, rather than using less directive treatments (eg, supportive counselling).Nonetheless, while these results are promising, firm conclusions regarding the comparative effectiveness and long-term impact of these treatments could not be drawn due to insufficient evidence. Further empirical research is needed to examine populations exposed to traumatic events and investigate which treatment approaches (or combination thereof) are more effective in the long-term.

55 A MOBILITY PROFILE OF STROKE PATIENTS ADMITTED TO A LEVEL 4 ACUTE HOSPITAL OVER A 6-MONTH PERIOD

Background

In order to best direct physiotherapy stroke resources and further service development it is important to characterise the mobility of stroke patients presenting to an acute hospital.

Methods

A previous audit completed in 2018 in the same organisation established that by using the Berg Balance Scale (BBS) and the Mobility Scale for Acute Stroke (MSAS) as admission outcome measures, a baseline profile could be established while limiting the floor and ceiling effects. A retrospective audit was completed of all patients referred to the stroke physiotherapy service admitted with acute stroke in a 6 month period. An excel spreadsheet was used to record patients’ admission BBS and MSAS. This was recorded along with the mainstay of physiotherapy treatment and discharge destination.

Results

145 stroke patients were assessed by stroke physiotherapy between Oct 2021 and April 2022. Of those patients 30% scored full marks on the MSAS which indicates that they were independently mobile with or without an aid post stroke. 26% of patients scored 3 or less on the BBS which would imply they were unable to sit without help.

Conclusion

This audit provides valuable information on the mobility profile of stroke patients presenting to an acute Level 4 hospital. On admission, patients seem to fall into 3 distinct categories based on their physical function post stroke. One group remained independently mobile post stroke, one group were heavily dependent being unable to sit without assistance and the final cohort requiring some level of supervision or assistance for mobility and balance. This information could be used to facilitate therapy and resource planning.

255 THE ROLE OF GERIATRIC MEDICINE IN CARE OF OLDER ADULTS WITH MAJOR TRAUMA

Background

In recent Major Trauma Audit Reports the most common cause of major trauma is low falls, 46-49% of injured patients were aged over 65. These are an important group to identify and to prioritise for geriatrician led MDT care. There is currently no specialist geriatric medicine service in Ireland for older adults with major trauma. We aimed to evaluate patients with major trauma currently co-managed by orthopaedic surgery and geriatric medicine, the role of geriatric medicine and the potential role of a major trauma geriatric service.

Methods

We reviewed local data collected for the Irish Hip Fracture Database to examine the incidence of major trauma presenting in older adults and the role of geriatric medicine. We included patients who had injuries in addition to hip fracture including radius, ulna, clavicle, humerus, rib, vertebra, pelvis fracture subdural haemorrhage, diffuse brain injury and traumatic subarachnoid haemorrhage.

Results

In 2020, there were 437 older adults admitted with hip fractures and likely 2185 patients presenting with fragility fractures. We identified 32(7%) patients who sustained other major injuries in addition to hip fracture. Nationally, these patients have a higher in-hospital mortality (11% v 5%). All of these patients had comprehensive geriatric assessment (CGA) and geriatrician-led MDT care. These patients are at high risk for poorer outcomes; delirium, pressure ulcers, hospital acquired infection and disability, prolonged length of stay, delayed transfers of care, premature institutionalisation and death.

Conclusion

There is a role for expansion of proactive early identification and geriatric medicine input for all older adults with major trauma, in addition to those with hip fractures and other injuries. The increased mortality in these patients has not previously been published. International evidence supports early intervention from a specialist geriatric medicine service, with CGA to provide exceptional, continuous and co-ordinated care.

168 AN EXPLORATION OF ATRIAL FIBRILLATION AND ANTICOAGULATION IN STROKE PATIENTS WHO UNDERGO THROMBECTOMY IN A TERTIARY THROMBECTOMY CENTRE

Background

Atrial Fibrillation is a significant cause of ischaemic stroke. Prevalence of atrial fibrillation in patients requiring thrombectomy is approximately 33%. Embolic thrombi which develop due to Atrial fibrillation may become targets for clot removal by thrombectomy in appropriate patients. Anticoagulation is one of the mainstays of treatment for atrial fibrillation.

Methods

A list of patients who had thrombectomy performed for ischaemic stroke in 2021 was compiled. Charts were reviewed to establish the prevalence of atrial fibrillation and the rates of appropriate dosing of anticoagulant. Of those who were not anticoagulated, we aimed to establish if there was a clear reason for this. This was performed in a tertiary referral centre with 24/7 access to thrombectomy.

Results

97 patients had thrombectomy performed for ischaemic stroke in 2021. 34/97(35%) had atrial fibrillation (21/97 pre-existing , 13/97 newly diagnosed on admission). 15/21 were anticoagulated and 6/21 were not anticoagulated at the time of their stroke. 5/6 had a clear reason documented for stopping anticoagulation. One patient had stopped anticoagulation due to cost. Of those with atrial fibrillation who were anticoagulated at the time of their stroke, 11 were anticoagulated with a Direct-Acting AntiCoagulant (DOAC) and four were anticoagulated with Warfarin. Of the Warfarin group, just one patients’ INR was therapeutic at the time of their stroke. Of the DOAC group, all were on the appropriate dose.

Conclusion

Stroke patients requiring thrombectomy are a group who may suffer the largest strokes. Incidence of atrial fibrillation was similar to previous studies. It was encouraging that there was a documented reason for all patients who were not anticoagulated, and that the DOAC dose was appropriate. Issues with therapeutic levels of Warfarin are further highlighted here. This study concludes that we may not be as bad at anticoagulation as we may think.

56 SARCOPENIA SCREENING FOR INDEPENDENTLY MOBILE STROKE PATIENTS IN AN ACUTE HOSPITAL SETTING

Background

Sarcopenia appears to be under-assessed and under-treated in the stroke population. It has been suggested by EWGSOP2 criteria, that if there is a clinical suspicion of sarcopenia, an intervention for this is appropriate. In order to establish the need for this in the independent stroke population an audit of the clinical prevalence of sarcopenia in independently mobile stroke patients was completed.

Methods

An excel spreadsheet was compiled of a convenient sample of stroke patients who were independently mobile post stroke. Their grip strength and five times sit to stand was audited along with the patient’s age and sex. This information was then used to assess for sarcopenia risk as per the EWGSOP2 guidelines.

Results

Fifteen patients were assessed, all of whom were independently mobile with or without an aid post admission for a primary diagnosis of acute stroke. Their age ranged from 64 to 86. Of these patients 93% were deemed likely to have sarcopenia based on their clinical assessment. This was based on grip strength measurements and time taken to complete five sit to stands. These clinical signs indicate low muscle strength and likely sarcopenia.

Conclusion

Currently no intervention is provided for these patients in relation to sarcopenia from the physiotherapy department. This audit indicates that this is currently an unmet need and these patients may benefit from an intervention to address this significant issue.

165 PHARMACIST-LED MEDICINES RECONCILIATION: AN OBSERVATIONAL STUDY TO EVALUATE INFORMATION SOURCES AS A QUALITY INDICATOR OF THE SERVICE

Background

Medicines Reconciliation (MR) involves obtaining a Best-Possible Medication History (BPMH) and is essential for reducing medication errors and adverse events. Recommendations on how best to undertake MR range from utilising the patient alone to using ≥2 sources (in addition to the patient). Few studies evaluate the use of >1 source as a measure of MR quality.

Methods

This observational study was undertaken in a major teaching hospital that provides a dedicated pharmacist-led MR service. Eligible patients (aged ≥65 years, admitted through the Emergency Department) were randomly recruited. MRs were compiled using 2 sources and compared to individual 1-source MRs (both in addition to patient/carer interview). Additional Medication Discrepancies (AMDs), or differences between 1-source and 2-source MR, were assessed and potential predictors analysed.

Results

A total of 114 patients were included. Community pharmacy was the most frequently used and most accurate source (full agreement in 97.4% of BPMHs). Two-thirds of MRs would not differ if either of the two sources were used in isolation, alongside patient/carer interview. The remaining MRs identified a total of 85 AMDs (1–6 per MR). The majority were drug omissions (49.4%). Most were deemed “low” potential clinical significance (59%). Higher patient/carer reliability was associated with lower incidence (p=0.001) and fewer AMDs (p=0.001).

Conclusion

Contrary to some international guidelines, using >1 source (in addition to patient/carer interview) does not add value to the BPMH in the majority of cases.

256 THE DEVELOPMENT OF A PATIENT AND CARER INFORMATION LEAFLET FOR PATIENTS FOLLOWING HIP FRACTURE

Background

Consistent delivery of high-quality information to family and caregivers can significantly improve patient experience and care during and after hospital admission. This became especially important with limited visiting hours during the COVID pandemic and our unit noted the need for appropriate written information. We aimed to complete a search of available resources nationally and internationally and develop our own information pack for distribution to our patients.

Methods

Literature search was conducted for available patient and carer information resources nationally and internationally including grey literature search. Key areas and patient priorities were identified. We then began developing a patient information booklet for distribution in our unit.

Results

We identified several key areas to be included in our information pack including what to expect during the hospital admission. This included pre-operative care, operative management, post-operative care especially delirium, pain, nutrition and continence promotion. Information regarding post-discharge care including off-site rehabilitation, rehabilitation at home and future actions including bone health and falls prevention interventions with home modification advice was also included. We developed a patient and caregiver information leaflet for our unit using data from the Irish Hip Fracture Database and our local unit practices and pathways to ensure information was relevant to our patients.

Conclusion

We completed the design of a patient and caregiver information leaflet highlighting important aspects of care post hip fracture in our unit.

Defining the role of neutrophils in the lung during infection: Implications for tuberculosis disease

Neutrophils are implicated in the pathogenesis of many diseases involving inflammation. Neutrophils are also critical to host defence and have a key role in the innate immune response to infection. Despite their efficiencies against a wide range of pathogens however, their ability to contain and combat Mycobacterium tuberculosis (Mtb) in the lung remains uncertain and contentious. The host response to Mtb infection is very complex, involving the secretion of various cytokines and chemokines from a wide variety of immune cells, including neutrophils, macrophages, monocytes, T cells, B cells, NK cells and dendritic cells. Considering the contributing role neutrophils play in the advancement of many diseases, understanding how an inflammatory microenvironment affects neutrophils, and how neutrophils interact with other immune cells, particularly in the context of the infected lung, may aid the design of immunomodulatory therapies. In the current review, we provide a brief overview of the mechanisms that underpin pathogen clearance by neutrophils and discuss their role in the context of Mtb and non-Mtb infection. Next, we examine the current evidence demonstrating how neutrophils interact with a range of human and non-human immune cells and how these interactions can differentially prime, activate and alter a repertoire of neutrophil effector functions. Furthermore, we discuss the metabolic pathways employed by neutrophils in modulating their response to activation, pathogen stimulation and infection. To conclude, we highlight knowledge gaps in the field and discuss plausible novel drug treatments that target host neutrophil metabolism and function which could hold therapeutic potential for people suffering from respiratory infections.

Evaluation of data imputation strategies in complex, deeply-phenotyped data sets: the case of the EU-AIMS Longitudinal European Autism Project

An increasing number of large-scale multi-modal research initiatives has been conducted in the typically developing population, e.g. Dev. Cogn. Neur. 32:43-54, 2018; PLoS Med. 12(3):e1001779, 2015; Elam and Van Essen, Enc. Comp. Neur., 2013, as well as in psychiatric cohorts, e.g. Trans. Psych. 10(1):100, 2020; Mol. Psych. 19:659–667, 2014; Mol. Aut. 8:24, 2017; Eur. Child and Adol. Psych. 24(3):265–281, 2015. Missing data is a common problem in such datasets due to the difficulty of assessing multiple measures on a large number of participants. The consequences of missing data accumulate when researchers aim to integrate relationships across multiple measures. Here we aim to evaluate different imputation strategies to fill in missing values in clinical data from a large (total N = 764) and deeply phenotyped (i.e. range of clinical and cognitive instruments administered) sample of N = 453 autistic individuals and N = 311 control individuals recruited as part of the EU-AIMS Longitudinal European Autism Project (LEAP) consortium. In particular, we consider a total of 160 clinical measures divided in 15 overlapping subsets of participants. We use two simple but common univariate strategies—mean and median imputation—as well as a Round Robin regression approach involving four independent multivariate regression models including Bayesian Ridge regression, as well as several non-linear models: Decision Trees (Extra Trees., and Nearest Neighbours regression. We evaluate the models using the traditional mean square error towards removed available data, and also consider the Kullback–Leibler divergence between the observed and the imputed distributions. We show that all of the multivariate approaches tested provide a substantial improvement compared to typical univariate approaches. Further, our analyses reveal that across all 15 data-subsets tested, an Extra Trees regression approach provided the best global results. This not only allows the selection of a unique model to impute missing data for the LEAP project and delivers a fixed set of imputed clinical data to be used by researchers working with the LEAP dataset in the future, but provides more general guidelines for data imputation in large scale epidemiological studies.

Utility of 3D printed models as adjunct in acetabular fracture teaching for Orthopaedic trainees

OBJECTIVE

To evaluate the use of 3-D printed models as compared to didactic lectures in the teaching of acetabular fractures for Orthopaedic trainees.

METHODS

This was a randomised prospective study conducted in a tertiary hospital setting which consisted of 16 Orthopaedic residents. Ten different cases of acetabular fracture patterns were identified and printed as 3-D models. The baseline knowledge of orthopaedic residents regarding acetabular fracture classification and surgical approach was determined by an x-ray based pre-test. Trainees were then randomly assigned into two groups. Group I received only lectures. Group II were additionally provided with 3-D printed models during the lecture. Participants were then assessed for comprehension and retention of teaching.

RESULTS

Sixteen trainees participated in the trial. Both Group 1 and 2 improved post teaching with a mean score of 2.5 and 1.9 to 4.4 and 6 out of 10 respectively. The post test score for fracture classification and surgical approach were significantly higher for 3-D model group (p < 0.05). Trainees felt that the physical characteristics of the 3-D models were a good representation of acetabular fracture configuration, and should be used routinely for teaching and surgical planning.

CONCLUSION

3-D printed model of real clinical cases have significant educational impact compared to lecture-based learning towards improving young trainees' understanding of complex acetabular fractures.

Care pathway for autistic children and their families in Europe

Introduction

Autism is a lifelong complex neurodevelopmental condition that affects brain development and behaviour with significant consequences for everyday life (WHO, 2018). Despite its personal, familial and societal impact, there is still a European-wide lack of harmonised guidelines about the support needed from early stages, the most sensitive time to gain positive future outcomes (Berajamo-Martin et al, 2019).

Objectives

The objectives were: 1. To analyse autistic children care pathway and patient/carer journey in three European countries: Italy, Spain and U.K. 2. To propose policy recommendations on how to improve this pathway.

Methods

To identify major barriers and treatment gaps, we conducted a rapid literature review of the care pathway in Europe and a survey aimed at parents or carers of autistic children ages 0 to 18 living in the three countries. The survey gathered information on screening, diagnosis, accessibility and support received before, during and after diagnosis. Members of the working group met to discuss results and propose policy recommendations.

Results

1. Current care pathway analysis showed the following treatment gaps: Long waiting time from first concerns until screening visit and confirmed diagnosis. Delayed or no access to intervention once diagnosis has been confirmed. Overall limited information about autism and how to access early detection services. Overall deficient support to families. 2. Please see Box 1 for our proposed policy recommendations.

Box 1. Policy recommendations

Conclusions

Our findings and recommendations will inform policy harmonisation in Europe to shorten long waiting times, diagnosis process and intervention, and therefore, improve autistic people and their families’ journey experience and quality of life.

Case Study: Soft Tissue Infection with Raoultella ornithinolytica

Raoultella ornithinolytica is a rare encapsulated Gram-negative aerobic and facultative anaerobic rod belonging to the Enterobacteriaceae family. It tends to inhabit water and soil environments and can be found on insects, fish, ticks, and termites, but can also found in the hospital environment.^1,2R ornithinolytica has been documented in respiratory, urinary, gastrointestinal, and biliary tract infections as well as bacteraemia and systemic infections but has rarely been documented in soft tissue infections.² This case study describes a recurrent paronychia infection secondary to R ornithinolytica in a young woman not responding to antibiotics and successfully treated with surgical management.

Analysis of an adaptive lead weighted ResNet for multiclass classification of 12-lead ECGs

Background. Twelve lead ECGs are a core diagnostic tool for cardiovascular diseases. Here, we describe and analyse an ensemble deep neural network architecture to classify 24 cardiac abnormalities from 12 lead ECGs.Method. We proposed a squeeze and excite ResNet to automatically learn deep features from 12-lead ECGs, in order to identify 24 cardiac conditions. The deep features were augmented with age and gender features in the final fully connected layers. Output thresholds for each class were set using a constrained grid search. To determine why the model made incorrect predictions, two expert clinicians independently interpreted a random set of 100 misclassified ECGs concerning left axis deviation.Results. Using the bespoke weighted accuracy metric, we achieved a 5-fold cross-validation score of 0.684, and sensitivity and specificity of 0.758 and 0.969, respectively. We scored 0.520 on the full test data, and ranked 2nd out of 41 in the official challenge rankings. On a random set of misclassified ECGs, agreement between two clinicians and training labels was poor (clinician 1:κ= -0.057, clinician 2:κ= -0.159). In contrast, agreement between the clinicians was very high (κ= 0.92).Discussion. The proposed prediction model performed well on the validation and hidden test data in comparison to models trained on the same data. We also discovered considerable inconsistency in training labels, which is likely to hinder development of more accurate models.

Bridging the Patient Engagement Gap in Research and Quality Improvement Utilizing the Henry Ford Flexible Engagement Model

PURPOSE

This paper was intended to share a flexible engagement model (FEM) for organizing a structure to obtain patient input regarding health care operations and research, provide greater detail on recruitment, retention, and dissemination strategies, and demonstrate successes and potential applications in other health care settings.

METHODS

Utilizing a pragmatic approach, the Patient-Engaged Research Center (PERC) at Henry Ford Health System developed the FEM, a 7-step process to introduce interested patients/caregivers to the patient advisor program and to follow up with placements. PERC developed a meeting evaluation to measure participant satisfaction. Retention and dissemination methods to keep participants consistently engaged included monthly email blasts, an annual patient advisor retreat, and inviting patient advisors to attend/present at local and national conferences.

RESULTS

As of January 2020, the program had 419 patient advisors. Almost 50% self-reported as Caucasian and 31% as African American; 73% were women, and most were 45-74 years of age. Recruitment methods proved effective, as 85% of advisors were initially engaged through print and digital marketing. Mean advisor orientation workshop evaluation scores regarding content, facilitators, and logistics were high, with all 4.5 or higher on a Likert scale of 1 (strongly negative) to 5 (strongly positive).

CONCLUSIONS

Given the FEM's flexible nature and adaptability, PERC has been successful in effectively leveraging the patient voice and experiences in research and health care delivery. Further research could investigate the model's generalizability, return on investment, and how to formally embed its methodology institutionally.

Outcomes in Nonagenarians with Hip Fractures Treated Conservatively and Surgically

Introduction

We aimed to assess the clinical outcomes in nonagenarians following a hip fracture. We also further investigated the factors that influence these outcomes, such as method of treatment (operative versus conservative), co-morbidities, and pre-morbid function.

Materials and methods

We studied 65 nonagenarians that were identifiable from our hospital hip fracture database. We reviewed various parameters of these patients admitted after sustaining a hip fracture (neck of femur or intertrochanteric) and investigated how these parameters affected patient outcomes. The main outcomes studied were: inpatient morbidity, and mortality at one year.

Results

Inpatient morbidity was more likely in patients with an ASA grade of 3 to 5. Urinary tract infection was the most common medical complication. The 1-year mortality was 15.4% and was significantly influenced by advancing age. Surgically managed patients had a 1-year mortality rate (14.3%) slightly less than non-operative patients (17.4%). Post injury mobility was significantly better in those who received operative treatment with 63% of surgical cases regaining ambulatory status versus 7% of conservatively managed patients.

Conclusions

We presented the outcomes of hip fractures in an extreme age group in the population. In nonagenarians with hip fractures surgery was associated with a 1-year mortality rate of 14.3% which is comparable to the general hip fracture population and less than the mortality rate of conservatively managed patients (17.4%). The primary advantage of surgery would be that two-thirds of patients return to ambulatory status. This information is useful to counsel patients and their families especially since the elderly are often more fearful of surgical intervention.

Preference for biological motion is reduced in ASD: implications for clinical trials and the search for biomarkers

BACKGROUND

The neurocognitive mechanisms underlying autism spectrum disorder (ASD) remain unclear. Progress has been largely hampered by small sample sizes, variable age ranges and resulting inconsistent findings. There is a pressing need for large definitive studies to delineate the nature and extent of key case/control differences to direct research towards fruitful areas for future investigation. Here we focus on perception of biological motion, a promising index of social brain function which may be altered in ASD. In a large sample ranging from childhood to adulthood, we assess whether biological motion preference differs in ASD compared to neurotypical participants (NT), how differences are modulated by age and sex and whether they are associated with dimensional variation in concurrent or later symptomatology.

METHODS

Eye-tracking data were collected from 486 6-to-30-year-old autistic (N = 282) and non-autistic control (N = 204) participants whilst they viewed 28 trials pairing biological (BM) and control (non-biological, CTRL) motion. Preference for the biological motion stimulus was calculated as (1) proportion looking time difference (BM-CTRL) and (2) peak look duration difference (BM-CTRL).

RESULTS

The ASD group showed a present but weaker preference for biological motion than the NT group. The nature of the control stimulus modulated preference for biological motion in both groups. Biological motion preference did not vary with age, gender, or concurrent or prospective social communicative skill within the ASD group, although a lack of clear preference for either stimulus was associated with higher social-communicative symptoms at baseline.

LIMITATIONS

The paired visual preference we used may underestimate preference for a stimulus in younger and lower IQ individuals. Our ASD group had a lower average IQ by approximately seven points. 18% of our sample was not analysed for various technical and behavioural reasons.

CONCLUSIONS

Biological motion preference elicits small-to-medium-sized case-control effects, but individual differences do not strongly relate to core social autism associated symptomatology. We interpret this as an autistic difference (as opposed to a deficit) likely manifest in social brain regions. The extent to which this is an innate difference present from birth and central to the autistic phenotype, or the consequence of a life lived with ASD, is unclear.

Evaluation of the impact of human immunodeficiency virus pre-exposure prophylaxis on new human immunodeficiency virus diagnoses during the COVID-19 pandemic

AIMS

The national PrEP programme launched in Ireland in November 2019 with tenofovir/emtricitabine free to those meeting eligibility criteria. We assessed the impact of the first year of the PrEP programme on new HIV diagnoses in the largest sexual health and HIV service in Ireland.

METHODS

A free PrEP service was established in November 2019. We reviewed the number of new diagnoses of HIV between November 2018-2019, before the introduction of the national PrEP programme and compared this with the number of new HIV diagnosis between November 2019-2020.

RESULTS

There were 95 new HIV diagnoses (63.3% MSM) between November 2018 and 2019 and 73 new HIV diagnoses (65.7% MSM) between November 2019 and 2020. There was a statistically significant decline in new HIV diagnoses between the 2 years (P = 0.0003). 546 patients were prescribed PrEP as of December 2020.106 patients (19.4%) changed their PrEP dosing regimen due to lockdown. 178 individuals (32.6%) had a rectal infection diagnosed.

CONCLUSION

There has been a reduction in new HIV diagnoses in our cohort (although this has occurred during a global pandemic). It is too early to say if PrEP reduces late presentations of HIV based on our findings. A significant number of rectal infections were identified in the PrEP clinic suggesting ongoing risk despite pandemic restrictions. Further research into sexual practices during COVID-19 is needed to assess if this had an impact on the lower rates of HIV acquisition.

160 TIME TO BIN ‘NEXT OF KIN’?—JUNIOR DOCTORS DEMONSTRATE POOR UNDERSTANDING OF THE TERM IN IRELAND

Background

‘Next of kin’ (NOK) is a term widely used in the healthcare setting in Ireland to indicate an individual that can be contacted in the event of an emergency when a patient is in hospital. While it has its origins in Irish inheritance law, the term confers no legal or decision-making authority to any other individuals on behalf of a patient in hospital. However, anecdotally, the term is commonly misunderstood with a false belief among healthcare staff that consent should be sought from the NOK when a patient is unable to do so. In this study we sought to assess current understanding of the term among Irish non-consultant hospital doctors (NCHDs).

Methods

Data was collected via an online survey, completed by NCHDs across a number of medical and surgical disciplines to investigate their understanding of the term. Descriptive analysis of data was performed in Excel.

Results

118 NCHDs completed the survey. While 110 (93.2%) believed a NOK was an emergency contact, 53 (44.9%) believed they assisted in decision making; 58 (49.2%) thought they could provide medical information about the patient. Forty-four doctors (37.3%) believed a NOK was permitted to make medical decisions while 59 (50%) felt they could provide consent on behalf of an incapacitated patient. Sixty-three (53.4%) believed a NOK had legal entitlement to information over and above that of another family member or friend.

Conclusion

This study highlights several misconceptions surrounding the term ‘next of kin’ in the Irish healthcare setting, particularly around the area of decision-making authority and consent. The term is confusing and unhelpful and should not be used in healthcare. ‘Contact person’ or ‘emergency contact’ are appropriate alternatives. Further education to NCHDs around consent and maintenance of patient autonomy is necessary.

Magnetic resonance imaging in the evaluation of idiopathic frequent premature ventricular complexes with normal ventricular function

Background

The role of cardiac magnetic resonance (CMR) imaging in the diagnostic evaluation of patients with frequent premature ventricular complexes (PVCs) and normal left ventricular ejection fraction (LVEF) remains unclear. Existing data has been predominantly derived from highly selected populations, that may overestimate the true prevalence of abnormal findings on CMR in this patient population.

Purpose

The aim of this study was 2-fold: 1) to establish the prevalence of CMR imaging abnormalities in a cohort with normal LVEF and high PVC burden; 2) to identify predictors of CMR imaging abnormalities in patients with frequent PVCs and normal LVEF.

Methods

In this cohort study, 211 patients (age 53.2±19 years; 41% male) with frequent PVCs (≥5%/24 h), of normal LVEF (≥50% by echocardiography) and no known underlying structural heart disease were prospectively enrolled from 2016–2020. Of these, 166 (79%) patients were symptomatic from their PVCs in the form of palpitations, fatigue, chest pain, dizziness, and/or dyspnea. Patients underwent CMR imaging (1.5 Tesla) with a late gadolinium enhancement (LGE) protocol at the time of enrollment for the detection of scarring and/or fibrosis.

Results

Patients had a median baseline echocardiographic LVEF of 60% (± 5%) with 195 (92%) of patients having a normal native QRS morphology. Median PVC burden of the study cohort was 16% (± 14%). CMR LGE abnormalities were found in 19 (9%) patients including 17 scans with non-ischemic LGE and 2 with ischemic LGE. Age &gt;60 (odds ratio [OR]: 3.20, 95% confidence interval [CI]: 1.20–8.51, p=0.020), male sex (OR: 4.67, 95% CI: 1.61–13.50, p=0.004), history of hypertension (OR: 3.43, 95% CI: 1.31–8.97, p=0.012), native QRS duration (OR: 1.03, 95% CI: 1.00–1.05, p=0.031), and history of non-sustained ventricular tachycardia (OR: 2.81, 95% CI: 1.03–7.68, p=0.044) were significantly associated with the presence of imaging abnormalities on CMR. Dominant PVC origin from the left ventricle had a positive trend (OR: 2.60, 95% CI: 0.99–7.66, p=0.083) to association with CMR imaging abnormalities. On multivariate analysis, male sex (OR: 4.10, 95% CI: 1.40–12.04, p=0.010) and history of hypertension (OR: 2.89, 95% CI: 1.08–7.75, p=0.035) remained significantly associated with the presence of CMR abnormalities. There was no association between CMR imaging abnormalities and the burden of PVCs or the number of PVC morphologies.

Conclusion

In this cohort, only 9% of patients with apparently idiopathic frequent PVCs and normal LVEF had concealed myocardial abnormalities on CMR imaging. Male sex and history of hypertension were associated with a higher rate of CMR abnormalities.

FFRCT and Invasive Coronary Angiography – assessing concordance in an unselected UK real world population

Background/Introduction

CT coronary angiography (CTCA) Fractional Flow Reserve (FFRCT) is a key investigation in chronic coronary syndrome (CCS) guidelines. FFR calculated from CTCA may help improve CTCA specificity for flow limiting disease, preventing unnecessary invasive coronary angiography (ICA).

Purpose

To (1) assess the treatment planning potential of FFRCT by determining the concordance of FFRCT with an ICA +/− invasive physiological assessment for the detection of flow limiting CAD in a real world NHS setting and (2) concordance sub-analysis of concordance of invasive iFR and FFRCT.

Methods

A single-centre retrospective analysis of a prospectively maintained clinical CTCA database. We identified patients with CCS who had CTCA FFRCT and subsequent ICA from August 2018 to January 2021. Concordance was assessed on a per patient and per vessel basis (major epicardial vessels: left main stem [LMS], left anterior descending artery [LAD], circumflex [LCx], right coronary artery [RCA]). Two non-invasive ischaemia thresholds were examined an FFRCT ≤0.8 and &lt;0.75 (2 cm distal to stenosis). This was compared to a clinical ICA assessment where a flow limiting lesion was defined as a stenosis &gt;70% (or &gt;50% in the LMS) and/or an end vessel iFR ≤0.89 / FFR ≤0.8. All vessels that underwent an iFR, at the interventionists discretion, were then assessed relative to their end-vessel FFRCT.

Results

565 patients had a CTCA with FFRCT and 164 patients had a subsequent ICA and were suitable for analysis. On a per patient basis 69% of those referred to ICA with an FFRCT ≤0.8 of at least one major epicardial vessel had any flow limiting CAD at ICA. With an FFRCT &lt;0.75 this was 73%. Table 1 illustrates the per vessel concordance.

A total of 120 vessels were included in the iFR subsection analysis. The mean FFRCT was 0.71 (±0.13) and mean iFR was 0.89 (±0.1). Accuracy was 54% (95% CI 45–63%) with a sensitivity of 89% (95% CI 76–96%), specificity 32% (95% CI 22–44%), positive predictive value 45% (95% CI 40–50%) and negative predictive value of 83% (95% CI 66–92%). A Pearson's correlation coefficient of 0.23 was found.

Conclusion

This study demonstrated that the negative predictive value of FFRCT was excellent, including importantly for LMS analysis. The specificity on a per vessel basis was good with the exception of the LAD assessment. This may have implications for interventional planning with this imaging modality. FFRCT correlated poorly with invasive iFR in this subsection analysis although selection bias may be contributing. There remains a significant proportion of patients referred for an ICA where no flow limiting CAD is found.

Optimal reconstructive strategies in the setting of post-mastectomy radiotherapy - A systematic review and network meta-analysis

BACKGROUND

A third of breast cancer patients require mastectomy. In some high-risk cases postmastectomy radiotherapy (PMRT) is indicated, threatening reconstructive complications. Several PMRT and reconstruction combinations are used. Autologous flap (AF) reconstruction may be immediate (AF→PMRT), delayed-immediate with tissue expander (TE [TE→PMRT→AF]) or delayed (PMRT→AF). Implant-based breast reconstruction (IBBR) includes immediate TE followed by PMRT and conversion to permanent implant (PI [TE→PMRT→PI]), delayed TE insertion (PMRT→TE→PI), and prosthetic implant conversion prior to PMRT (TE→PI→PMRT).

AIM

Perform a network metanalysis (NMA) assessing optimal sequencing of PMRT and reconstructive type.

METHODS

A systematic review and NMA was performed according to PRISMA-NMA guidelines. NMA was conducted using R packages netmeta and Shiny.

RESULTS

16 studies from 4182 identified, involving 2322 reconstructions over three decades, met predefined inclusion criteria. Studies demonstrated moderate heterogeneity. Multiple comparisons combining direct and indirect evidence established AF-PMRT as the optimal approach to avoid reconstructive failure, compared with IBBR strategies (versus PMRT→TE→PI; OR [odds ratio] 0.10, CrI [95% credible interval] 0.02 to 0.55; versus TE→PMRT→PI; OR 0.13, CrI 0.02 to 0.75; versus TE→PI→PMRT OR 0.24, CrI 0.05 to 1.05). PMRT→AF best avoided infection, demonstrating significant improvement versus PMRT→TE→PI alone (OR 0.12, CrI 0.02 to 0.88). Subgroup analysis of IBBR found TE→PI→PMRT reduced failure rates (OR 0.35, CrI 0.15-0.81) compared to other IBBR strategies but increased capsular contracture.

CONCLUSION

Immediate AF reconstruction is associated with reduced failure in the setting of PMRT. However, optimal reconstructive strategy depends on patient, surgeon and institutional factors. If IBBR is chosen, complication rates decrease if performed prior to PMRT.

AB0913-PARE METHOTREXATE FOR RHEUMATOID ARTHRITIS: PATIENT PERSPECTIVES ON MONITORING IN PRIMARY CARE

Background:

Monotherapy with methotrexate (MTX) is one first-line option for newly diagnosed Rheumatoid Arthritis (RA)1. Although treatment is usually commenced by a specialist, repeat prescribing and monitoring responsibilities often lie with primary care. While inadequate monitoring is a safety concern, unnecessary duplication of monitoring invariably has cost implications for General Practice (GP).

Objectives:

To ensure that patients in one South-West GP practice who are taking oral MTX for RA are appropriately monitored in line with current guidance from the British Society of Rheumatology (BSR). Current guidance recommends that once a stable MTX dose is maintained for six weeks, followed by monthly bloods for the next three months, that at least twelve weekly blood monitoring is sufficient from then on1.

Methods:

A randomised sample of 50 patients registered in one South-West GP practice that were taking a stable dose oral MTX for RA; for at least 6 months; was collected. The length of time between the patient’s two most recent blood tests was recorded. A random selection of ten patients with more frequent monitoring than BSR guidance suggest were asked a series of questions to determine patient perspectives on reasons for monitoring frequency.

Results:

58% of patients had more frequent monitoring bloods than current BSR guidelines recommend. Within this group, the mode frequency of monitoring was four weeks, in line with the previous National guidance which was superseded in 20172.The most common themes in patient’s perspectives on monitoring frequency were:

a.Previous abnormal blood results requiring close monitoring

b.Multiple disease modifying anti-rheumatoid drug (DMARD) regimes that included MTX

c.Patient preference

d.Unclear or unknown reason

The purported increased monitoring for multiple DMARD regimes were not in line with current national guidelines1.

Conclusion:

This audit demonstrates that over half of patients taking MTX for RA in one GP practice are having more frequent blood monitoring than BSR guidance suggests is necessary. Furthermore, it demonstrates that patient’s understanding of their perceived need for increased monitoring is largely inaccurate or unclear to them. There is a clear deficit in patient education surrounding monitoring frequency which must be addressed in order to empower patients, as well as reducing unnecessary duplication of blood tests. As a result of this audit, patient education on MTX monitoring frequency was formally introduced as part of the RA annual patient review. An information sheet with these monitoring requirements was produced to aid practitioners in the education process.
