RESUMEN

Cancer patients seeking emergency care can be vulnerable in increasingly overcrowded Emergency Departments and timely delivery of care is often aspirational rather than reality in many acute care systems. Ambulatory emergency care and its various international models are recognized as contributing to the safety and sustainability of emergency care services. This schema can logically be extended to the emergency oncology setting. The recent proliferation of immune checkpoint inhibitors (ICIs) has led to another opportunity for the management of oncologic complications in the ambulatory emergency care setting. More nuanced risk stratification of currently perceived high-risk toxicities may also afford the opportunity to personalize acute management. Virtual wards, which predominantly provide virtual monitoring only, and hospital at home services, which provide more comprehensive in-person assessment and interventions, may be well suited to supporting care for ICI toxicity alongside hospital-based assessment. Emergency management guidelines for immune-mediated toxicities will increasingly need to be both pragmatic and deliverable, especially as larger numbers of patients will present outside cancer centers. Identifying and modelling those suitable for emergency ambulatory care is integral to achieving this.

RESUMEN

BACKGROUND: Tackling problematic polypharmacy requires tailoring the use of medicines to individual needs and circumstances. This may involve stopping medicines (deprescribing) but patients and clinicians report uncertainty on how best to do this. The TAILOR medication synthesis sought to help understand how best to support deprescribing in older people living with multimorbidity and polypharmacy. OBJECTIVES: We identified two research questions: (1) what evidence exists to support the safe, effective and acceptable stopping of medication in this patient group, and (2) how, for whom and in what contexts can safe and effective tailoring of clinical decisions related to medication use work to produce desired outcomes? We thus described three objectives: (1) to undertake a robust scoping review of the literature on stopping medicines in this group to describe what is being done, where and for what effect; (2) to undertake a realist synthesis review to construct a programme theory that describes 'best practice' and helps explain the heterogeneity of deprescribing approaches; and (3) to translate findings into resources to support tailored prescribing in clinical practice. DATA SOURCES: Experienced information specialists conducted comprehensive searches in MEDLINE, Cumulative Index to Nursing and Allied Health Literature, Web of Science, EMBASE, The Cochrane Library (Cochrane Database of Systematic Reviews, Cochrane Central Register of Controlled Trials), Joanna Briggs Institute Database of Systematic Reviews and Implementation Reports, Google (Google Inc., Mountain View, CA, USA) and Google Scholar (targeted searches). REVIEW METHODS: The scoping review followed the five steps described by the Joanna Briggs Institute methodology for conducting a scoping review. The realist review followed the methodological and publication standards for realist reviews described by the Realist And Meta-narrative Evidence Syntheses: Evolving Standards (RAMESES) group. Patient and public involvement partners ensured that our analysis retained a patient-centred focus. RESULTS: Our scoping review identified 9528 abstracts: 8847 were removed at screening and 662 were removed at full-text review. This left 20 studies (published between 2009 and 2020) that examined the effectiveness, safety and acceptability of deprescribing in adults (aged ≥ 50 years) with polypharmacy (five or more prescribed medications) and multimorbidity (two or more conditions). Our analysis revealed that deprescribing under research conditions mapped well to expert guidance on the steps needed for good clinical practice. Our findings offer evidence-informed support to clinicians regarding the safety, clinician acceptability and potential effectiveness of clinical decision-making that demonstrates a structured approach to deprescribing decisions. Our realist review identified 2602 studies with 119 included in the final analysis. The analysis outlined 34 context-mechanism-outcome configurations describing the knowledge work of tailored prescribing under eight headings related to organisational, health-care professional and patient factors, and interventions to improve deprescribing. We conclude that robust tailored deprescribing requires attention to providing an enabling infrastructure, access to data, tailored explanations and trust. LIMITATIONS: Strict application of our definition of multimorbidity during the scoping review may have had an impact on the relevance of the review to clinical practice. The realist review was limited by the data (evidence) available. CONCLUSIONS: Our combined reviews recognise deprescribing as a complex intervention and provide support for the safety of structured approaches to deprescribing, but also highlight the need to integrate patient-centred and contextual factors into best practice models. FUTURE WORK: The TAILOR study has informed new funded research tackling deprescribing in sleep management, and professional education. Further research is being developed to implement tailored prescribing into routine primary care practice. STUDY REGISTRATION: This study is registered as PROSPERO CRD42018107544 and PROSPERO CRD42018104176. FUNDING: This project was funded by the National Institute for Health and Care Research (NIHR) Health Technology Assessment programme and will be published in full in Health Technology Assessment; Vol. 26, No. 32. See the NIHR Journals Library website for further project information.


Many patients take multiple medicines, every day, on a long-term basis. Some feel overloaded by their medicines. However, both doctors and patients have told us that they feel anxious about knowing when and how to safely stop medicines. TAILOR aimed to help by providing the information that doctors and patients need to make individual (tailored) decisions about whether or not to stop (deprescribe) medicines. We had two research questions and so used a different research method to answer each. Both methods involved us first finding all the published research looking at deprescribing for older people living with long-term conditions and using five or more medicines a day. Our first (scoping) review produced a map of what we know about deprescribing: how it is done and if it is safe. We found evidence that structured deprescribing can be safe and acceptable to clinicians, but specific effects were very varied and patient views were often not reported. Our team's patient partners continuously reminded us that medicines mean more to individuals than just a medical effect (e.g. a 'tablet for my blood pressure'), meaning that our research needed to describe good person-centred deprescribing. Our second (realist) review focused on this by looking at if and how tailored deprescribing decisions happen. Our results showed that health-care services need to give clinicians the permission and resources they need to work with patients to develop a joint understanding of the value of medicines, to guide decisions about using/changing medicines, and so to build and maintain trust. Our findings remind us that decisions about medicines are personal. We need to remember that any changes in medicines affect not just an individual's disease, but also their understanding of their health and health care. Our work makes recommendations on how future practice and research can be more person centred. We are now working with patients and health-care professionals to share our findings with a wide audience.

RESUMEN

BACKGROUND: Medical problems during pregnancy are the leading cause of maternal mortality in the UK. Pregnant women often present through acute services to the medical team, requiring timely access to appropriate services, physicians trained to manage medical problems in pregnancy, with locally agreed guidance available. METHODS: Data were collected through the Society for Acute Medicine Benchmarking Audit, a national audit of service delivery and patient care in acute medicine over a 24 hour period. RESULTS: One hundred and thirty hospitals participated: 5.5% had an acute medicine consultant trained in obstetric medicine, and 38% of hospitals had a named lead for maternal medicine. This was not related to hospital size (p = 0.313). Sixty-four units had local guidelines for medical problems in pregnancy; 43% had a local guideline for venous thromboembolism in pregnancy. Centres with a named lead had more guidelines (p = 0.019). CONCLUSION: Current provision of services within acute medicine for pregnant women does not meet national recommendations.

RESUMEN

INTRODUCTION: Reliable rapid testing for COVID-19 is needed in care homes to reduce the risk of outbreaks and enable timely care. This study aimed to examine the usability and test performance of a point of care polymerase chain reaction (PCR) test for detection of SARS-CoV-2 (POCKITTM Central) in care homes. METHODS: POCKITTM Central was evaluated in a purposeful sample of four UK care homes. Test agreement with laboratory real-time PCR and usability and used errors were assessed. RESULTS: No significant usability-related hazards emerged, and the sources of error identified were found to be amendable with minor changes in training or test workflow. POCKITTM Central has acceptable sensitivity and specificity based on RT-PCR as the reference standard, especially for symptomatic cases.Asymptomatic specimens showed 83.3% (95% confidence interval (CI): 35.9-99.6%) positive agreement and 98.7% negative agreement (95% CI: 96.2-99.7%), with overall prevalence and bias-adjusted kappa (PABAK) of 0.965 (95% CI: 0.932- 0.999). Symptomatic specimens showed 100% (95% CI: 2.5-100%) positive agreement and 100% negative agreement (95% CI: 85.8-100%), with overall PABAK of 1.Recommendations are provided to mitigate the frequency of occurrence of the residual use errors observed. Integration pathways were discussed to identify opportunities and limitations of adopting POCKIT™ Central for screening and diagnostic testing purposes. CONCLUSIONS: Point-of-care PCR testing in care homes can be considered with appropriate preparatory steps and safeguards. Further diagnostic accuracy evaluations and in-service evaluation studies should be conducted, if the test is to be implemented more widely, to build greater certainty on this initial exploratory analysis.

RESUMEN

BACKGROUND: Demand on hospital emergency departments for paediatric problems is increasing. However, the volume and nature of paediatric health demands placed on other parts of the urgent care system have not been explored. This understanding is an important first step in developing and improving out-of-hospital care. We aimed to describe the volume, nature, and outcomes of paediatric contacts with out-of-hours general practice (OOH GP). We performed a retrospective service evaluation using data from 12 months of paediatric patient contacts with the Oxfordshire OOH GP service. METHODS: A database of contacts with the Oxfordshire OOH GP service was created for a 12 month period from December 2014 to November 2015. Descriptive statistics were calculated using SPSS Version 25. RESULTS: 27,455 contacts were made by 18,987 individuals during a 12 month period. The majority of these were for children aged under 5. Over 70% of contacts were at the weekend. The peak contact period was between 18:30 and 21:30. Over 40% of contacts resulted in advice only (no onward referral, requirement for GP follow up, or prescription). 19.7% of contacts resulted in an antibiotic prescription, most commonly those linked with ear, chest, and throat infections. DISCUSSION: Paediatric contacts with the Oxfordshire OOH GP service were predominantly in younger age groups and in the evening, with 19.7% resulting in an antibiotic prescription. Almost half of the contacts had no follow up or prescription, suggesting non-prescribing health care professionals could be involved in providing care in OOH GP. Further research should consider how children and their parents can be best supported to optimise OOH consulting.

RESUMEN

BACKGROUND: Infection is common in older adults. Serious infection has a high mortality rate and is associated with unplanned hospital admissions. Little is known about the factors that prompt older patients to seek medical advice when they may have an infection. AIM: To explore the symptoms of infection from the perspective of older adults, and when and why older patients seek healthcare advice for a possible infection. DESIGN AND SETTING: A qualitative interview study among adults aged ≥70 years with a clinical diagnosis of infection recruited from ambulatory care units in Oxford, UK. METHOD: Interviews were semi-structured and based on a flexible topic guide. Participants were given the option to be interviewed with their carer. Thematic analysis was facilitated using NVivo (version 11). RESULTS: A total of 28 participants (22 patients and six carers) took part. Patients (aged 70-92 years) had experienced a range of different infections. Several early non-specific symptoms were described (fever, feeling unwell, lethargy, vomiting, pain, and confusion/delirium). Internally minimising symptoms was common and participants with historical experience of infection tended to be better able to interpret their symptoms. Factors influencing seeking healthcare advice included prompts from family, specific or intolerable symptoms, symptom duration, and being unable to manage with self-care. For some, not wanting to be a burden affected their desire to seek help. CONCLUSION: Tailored advice to older adults highlighting early symptoms of infection may be beneficial. Knowing whether patients have had previous experience of infection may help healthcare professionals in assessing older patients with possible infection.

RESUMEN

BACKGROUND: The world has an ageing population. Infection is common in older adults; serious infection has a high mortality rate and is associated with unplanned admissions. In the UK, general practitioners (GPs) must identify which older patients require admission to hospital and provide appropriate care and support for those staying at home. OBJECTIVES: To explore attitudes of UK GPs towards referring older patients with suspected infection to hospital, how they weigh up the decision to admit against the alternatives and how alternatives to admission could be made more effective.Methods. Qualitative study using semi-structured interviews. GPs were purposively sampled from across the UK to achieve maximum variation in terms of GP role, experience and practice population. Interview transcripts were coded and analysed using a modified framework approach. RESULTS: GPs' key influences on decision making were grouped into patient, GP and system factors. Patient factors included clinical factors, social factors and shared decision making. GP factors included gut instinct, risk management and acknowledging an associated personal emotional burden. System factors involved weighing up the pressure on secondary care beds against increasing GP workload. GPs described that finding an alternative to admission could be more time consuming, complex to arrange or were restricted by lack of capacity. CONCLUSION: GPs need to be empowered to make safe decisions about place of care for older adults with suspected infection. This may mean developing strategies to support decision making as well as improving the ease of access to, and capacity of, any alternatives to admission.

RESUMEN

OBJECTIVES: Tackling the harm associated with acute kidney injury (AKI) is a global priority. In England, a national computerised AKI algorithm is being introduced across the National Health Service (NHS) to drive this change. The study sought to maximise its clinical utility and minimise the potential for burden on clinicians and patients in primary care. DESIGN: An appropriateness ratings evaluation using the RAND/UCLA Appropriateness Method. SETTING: Clinical scenarios were developed to test the timeliness in (1) communication of AKI warning stage test results from clinical pathology services to primary care, and (2) primary care clinician response to an AKI warning stage test result. PARTICIPANTS: A 10-person panel was purposively sampled with representation from clinical biochemistry, acute and emergency medicine and general practice. General practitioners (GPs) represented typical practice in relation to rural and urban practice, out of hours care, GP commissioning and those interested in reducing the impact of medicalisation and 'overdiagnosis'. RESULTS: There was agreement that delivery of AKI warning stage test results through interruptive methods of communication (ie, telephone) from laboratories to primary care was the appropriate next step for patients with an AKI warning stage 3 test result. In the context of acute illness, waiting up to 72 hours to respond to an AKI warning stage test result was deemed an inappropriate action in 62 out of the 65 (94.5%) cases. There was agreement that a clinician response was required within 6 hours, or less, in 39 out of 40 (97.5%) clinical cases relating AKI warning stage test results in the presence of moderate hyperkalaemia. CONCLUSIONS: The study has informed national guidance to support a timely and calibrated response to AKI warning stage test results for adults in primary care. Further research is needed to support effective implementation, with a view to examine the effect on health outcomes and costs.

RESUMEN

OBJECTIVES: Since 2006, general practitioners (GPs) in England, UK, have been incentivised to keep a register and monitor patients with chronic kidney disease (CKD) stages 3-5. Despite tensions and debate around the merit of this activity, there has been little qualitative research exploring clinician perspectives on monitoring early-stage CKD in primary care. This study aimed to examine and understand a range of different healthcare professional views and experiences of identification and monitoring in primary care of early-stage CKD, in particular stage 3. DESIGN: Qualitative design using semistructured interviews. SETTING: National Health Service (NHS) settings across primary and secondary care in South West England, UK. PARTICIPANTS: 25 clinicians: 16 GPs, 3 practice nurses, 4 renal consultants and 2 public health physicians. RESULTS: We identified two related overarching themes of dissonance and consonance in clinician perspectives on early-stage CKD monitoring in primary care. Clinician dissonance around clinical guidelines for CKD monitoring emanated from different interpretations of CKD and different philosophies of healthcare and moral decision-making. Clinician consonance centred on the need for greater understanding of renal decline and increasing proteinuria testing to reduce overdiagnosis and identify those patients who were at risk of progression and further morbidity and who would benefit from early intervention. Clinicians recommended adopting a holistic approach for patients with CKD representing a barometer of overall health. CONCLUSIONS: The introduction of new National Institute for Health and Care Excellence (NICE) CKD guidelines in 2014, which focus the meaning and purpose of CKD monitoring by increased proteinuria testing and assessment of risk, may help to resolve some of the ethical and moral tensions clinicians expressed regarding the overmedicalisation of patients with a CKD diagnosis.

RESUMEN

BACKGROUND: The Age, Blood pressure, Clinical features, Duration of symptoms, Diabetes (ABCD2) score can be used to predict early recurrent stroke risk following Transient ischemic attack (TIA). Given that recurrent stroke risk can be as high as 20% in the first week, international guidelines recommend "high-risk" TIAs (ABCD2 >3) be seen by specialist services such as dedicated acute neurovascular clinics within 24 hours. The goal of this study was to examine the associations of both quality of referrals to a specialist acute clinic and of "guideline congruence" of time-to-clinic consultation after TIA/minor stroke. We hypothesized high-quality referrals containing key clinical elements would be associated with greater guideline congruence. METHODS: A retrospective analysis of referrals to an acute neurovascular clinic within a tertiary care hospital of consecutive patients with TIA/minor stroke. Quality of general practitioner and emergency department referrals was defined on the basis of information content enabling ABCD2-based risk stratification by the clinic triage service. Time-to-clinic consultation was used to define "guideline congruence." RESULTS: Referrals of 148 consecutive eligible patients were reviewed. Sixty-six percent of cases were subsequently neurologist-diagnosed as TIA or minor stroke. Seventy-nine percent were referred by general practitioners. Fifty-three percent of referrals were of high quality, but quality was not associated with guideline congruence. Of the high-risk patients, only 3.6% were seen at the clinic within 24 hours of index event and 31.3% within 24 hours of referral. CONCLUSIONS: Current guidelines are pathophysiologically logical and evidence based, but are difficult to implement. Improving quality of primary-secondary communication by improved referral quality is unlikely to improve guideline compliance. Alternative strategies are needed to reduce recurrent stroke risk after TIA/minor stroke.

RESUMEN

BACKGROUND: Self-monitoring is increasingly recommended as a method of managing cardiovascular disease. However, the design, implementation and reproducibility of the self-monitoring interventions appear to vary considerably. We examined the interventions included in systematic reviews of self-monitoring for four clinical problems that increase cardiovascular disease risk. METHODS: We searched Medline and Cochrane databases for systematic reviews of self-monitoring for: heart failure, oral anticoagulation therapy, hypertension and type 2 diabetes. We extracted data using a pre-specified template for the identifiable components of the interventions for each disease. Data was also extracted on the theoretical basis of the education provided, the rationale given for the self-monitoring regime adopted and the compliance with the self-monitoring regime by the patients. RESULTS: From 52 randomized controlled trials (10,388 patients) we identified four main components in self-monitoring interventions: education, self-measurement, adjustment/adherence and contact with health professionals. Considerable variation in these components occurred across trials and conditions, and often components were poorly described. Few trials gave evidence-based rationales for the components included and self-measurement regimes adopted. CONCLUSIONS: The components of self-monitoring interventions are not well defined despite current guidelines for self-monitoring in cardiovascular disease management. Few trials gave evidence-based rationales for the components included and self-measurement regimes adopted. We propose a checklist of factors to be considered in the design of self-monitoring interventions which may aid in the provision of an evidence-based rationale for each component as well as increase the reproducibility of effective interventions for clinicians and researchers.

RESUMEN

This study reports FDG-PET findings in Wernicke-Korsakoff patients. Twelve patients suffering amnesia arising from the Korsakoff syndrome were compared with 10 control subjects without alcohol-related disability. Subjects received [18F]-fluorodeoxyglucose (FDG-PET) imaging as well as neuropsychological assessment and high-resolution MR imaging with volumetric analysis. Volumetric MRI analysis had revealed thalamic and mamillary body atrophy in the patient group as well as frontal lobe atrophy with relative sparing of medial temporal lobe structures. Differences in regional metabolism were identified using complementary region of interest (ROI) and statistical parametric mapping (SPM) approaches employing either absolute methods or a reference region approach to increase statistical power. In general, we found relative hypermetabolism in white matter and hypometabolism in subcortical grey matter in Korsakoff patients. When FDG uptake ratios were examined with occipital lobe metabolism as covariate reference region, Korsakoff patients showed widespread bilateral white matter hypermetabolism on both SPM and ROI analysis. When white matter metabolism was the reference covariate; Korsakoff patients showed relative hypometabolism in the diencephalic grey matter, consistent with their known underlying neuropathology, and medial temporal and retrosplenial hypometabolism, interpreted as secondary metabolic effects within the diencephalic-limbic memory circuits. There was also evidence of a variable degree of more general frontotemporal neocortical hypometabolism on some, but not all, analyses.
