Testing and characterization of herding dogs' behaviors.

Breeding for phenotype in herding dogs (HDs) mainly relies on their performance in national field trial competitions, which has been shown to be inadequate for identifying HDs suited for real livestock farming conditions. In this study, a different field trial with a new scoring system consisting of 28 items to consider was designed to assess young HDs, the results of which culminated in a statement of adequate phenotype (AP) or non-adequate phenotype (NAP). An AP HD was defined as being able: to control the direction of a flock, to keep it grouped close to a handler when needed, to confront animals it is dealing with in a respectful manner, and able to create movement of the flock without excessive disturbance, threatening or attacking it through chasing, or uncontrolled biting. This innovative trial is composed of a pre-test (PT) and a test (T) phase. To evaluate its efficiency in detecting AP/NAP, 460 French Border Collies aged between 8 and 24 mo, underwent the trial. Its average duration (PT + T) was 3 min and 16 s (SD = 26 s). According to experts' assessments (Gold Standard), 16.5% of tested HD reached an AP score, and the Idele scoring system correctly identified 93.3% of them (sensitivity). Specificity and accuracy values were of 96.1% and 95.7%, respectively (P value < 0.0004). Recursive feature elimination identified 25 of the 118 features (categories of items) from the scoring system as significant predictors of AP/NAP. An AP HD was statistically defined as a dog who completed the PT and T phases, showed keenness, correct position in relation to the handler, and absence of prey drive. Four environmental effects significantly influenced AP/NAP: the field trial session, the owner's experience with HDs, the conditions of the HD's first contact with livestock, and the type of livestock with which the HD is accustomed to working (P-values <0.0005, <0.05, <0.05, and <0.007, respectively). Inter-evaluator agreement was substantial (0.70). The field trial proved to be a short, easily implemented, standardized, reproducible method for detecting AP/NAP. Hence, the field trial and its scoring system could provide a basis for a breeding program based on phenotype pending additional testing of HDs and genetic analyses.

Herding dogs are extremely useful in handling all types of livestock. They are selectively bred for success in herding dog competitions, but the abilities which that to success in these are not always the same as those needed on a farm. To produce efficient herding dogs, other abilities therefore needed to be tested, via new trials. So, a new field trial, with a specific scoring system, was set up and tried out using 460 young French Border Collies, with the aim of correctly assessing herding dogs that would be fully adapted to French farmers' needs. This corresponded to an "Adequate Phenotype". A herding dog with an adequate phenotype was defined as being able: to control the direction of a flock, to keep it grouped close to the handler when needed, to confront the animals it is dealing with in a respectful manner, and able to create movement of the flock without excessive disturbance, threatening or attacking through chasing or uncontrolled biting. The new protocol was found efficient in detecting such herding dogs. Moreover, it was easy to set up, short, standardized, and reproducible.

[Sometimes less is more. Preventing overdiagnosis by sharing decisions]. / Moins, c'est parfois mieux . Prévenir le surdiagnostic en partageant les décisions.

In this article, we will define «quaternary prevention¼, which consists in minimizing the iatrogenic effects of medical interventions, and more specifically the notion of «overdiagnosis¼. We will then discuss how a poor appreciation of the risks, on the part of both patients and clinicians, seems to fuel the phenomenon. We will discuss the interest of placing quaternary prevention within the broader framework of Shared Decision Making. We will focus on one of the stages of Shared Decision Making process, that of risk communication. Finally, we'll conclude that, fundamentally, clinicians should not only share information with patients, but also the power to decide.

Dans cet article, nous définirons la «prévention quaternaire¼, qui consiste à minimiser les effets iatrogènes de nos interventions et plus particulièrement de la notion de «surdiagnostic¼. Ensuite, nous discuterons en quoi une mauvaise appréciation des risques, chez les patients comme chez les thérapeutes, semble nourrir le phénomène. Nous discuterons de l'intérêt de replacer la prévention quaternaire dans le cadre plus large de la prise de décision médicale partagée (DMP) («Shared Decision Making¼). Nous nous attarderons sur une des étapes du processus de prise de DMP, celle de la communication des risques. Enfin nous conclurons que, fondamentalement, il s'agit pour les thérapeutes de non seulement partager l'information avec les patients, mais aussi le pouvoir de décider.

Integration, effectiveness and costs of different models of primary health care provision for people who are homeless: an evaluation study.

Background: There is a high prevalence of health problems among single people who are homeless. Specialist primary health care services for this population have been developed in several locations across England; however, there have been very few evaluations of these services. Objectives: This study evaluated the work of different models of primary health care provision in England to determine their effectiveness in engaging people who are homeless in health care and in providing continuity of care for long-term conditions. It concerned single people (not families or couples with dependent children) staying in hostels, other temporary accommodation or on the streets. The influence on outcomes of contextual factors and mechanisms (service delivery factors), including integration with other services, were examined. Data from medical records were collated on participants' use of health care and social care services over 12 months, and costs were calculated. Design and setting: The evaluation involved four existing Health Service Models: (1) health centres primarily for people who are homeless (Dedicated Centres), (2) Mobile Teams providing health care in hostels and day centres, (3) Specialist GPs providing some services exclusively for patients who are homeless and (4) Usual Care GPs providing no special services for people who are homeless (as a comparison). Two Case Study Sites were recruited for each of the specialist models, and four for the Usual Care GP model. Participants: People who had been homeless during the previous 12 months were recruited as 'case study participants'; they were interviewed at baseline and at 4 and 8 months, and information was collected about their circumstances and their health and service use in the preceding 4 months. Overall, 363 participants were recruited; medical records were obtained for 349 participants. Interviews were conducted with 65 Case Study Site staff and sessional workers, and 81 service providers and stakeholders. Results: The primary outcome was the extent of health screening for body mass index, mental health, alcohol use, tuberculosis, smoking and hepatitis A among participants, and evidence of an intervention if a problem was identified. There were no overall differences in screening between the models apart from Mobile Teams, which scored considerably lower. Dedicated Centres and Specialist GPs were more successful in providing continuity of care for participants with depression and alcohol and drug problems. Service use and costs were significantly higher for Dedicated Centre participants and lower for Usual Care GP participants. Participants and staff welcomed flexible and tailored approaches to care, and related services being available in the same building. Across all models, dental needs were unaddressed and staff reported poor availability of mental health services. Limitations: There were difficulties recruiting mainstream general practices for the Usual Care GP model. Medical records could not be accessed for 14 participants of this model. Conclusions: Participant characteristics, contextual factors and mechanisms were influential in determining outcomes. Overall, outcomes for Dedicated Centres and for one of the Specialist GP sites were relatively favourable. They had dedicated staff for patients who were homeless, 'drop-in' services, on-site mental health and substance misuse services, and worked closely with hospitals and homelessness sector services. Funding: This project was funded by the National Institute for Health and Care Research (NIHR) Health and Social Care Delivery Research programme (HSDR 13/156/03) and will be published in full in Health and Social Care Delivery Research; Vol. 11, No. 16.

Health problems are common among single people who are homeless, but there is little evidence of the best ways to deliver primary health care to them. This study evaluated four types of services (models) that are in existence: (1) health centres primarily for people who are homeless (Dedicated Centres); (2) Mobile Teams that provide health care in hostels and day centres; (3) Specialist GPs that have some services exclusively for patients who are homeless; and (4) Usual Care GPs providing health care to all patients, with no special services for people who are homeless. The study concentrated on single people (not homeless families or couples with dependent children) staying in hostels, other temporary accommodation and on the streets. Overall, 363 patients at these practices who had been homeless in the previous 12 months participated, and information was collected from them over a 12-month period. We examined the extent to which screening for different health conditions was undertaken, and to which treatment and follow-up care were provided for participants with chronic respiratory problems, depression, alcohol problems and drug problems. Information was gathered from their medical records about use of health and social care services over 12 months. Overall, outcomes for Dedicated Centres and for one of the Specialist GP sites were more favourable. They had staff working specifically with patients who were homeless; provided flexible 'drop-in' services instead of requiring patients to book appointments; and worked closely with mental health, alcohol and drug services, and with hostels, day centres and street outreach teams. Participants were also more satisfied with the health care they received from the specialist models, and were more likely to say that they had confidence and trust in doctors and nurses at these sites. Across all models, dental needs were unaddressed and staff reported poor availability of mental health services.

Impact of emotional competence on physicians' clinical reasoning: a scoping review protocol.

INTRODUCTION: Clinical reasoning (CR) is a key competence for physicians and a major source of damaging medical errors. Many strategies have been explored to improve CR quality, most of them based on knowledge enhancement, cognitive debiasing and the use of analytical reasoning. If increasing knowledge and fostering analytical reasoning have shown some positive results, the impact of debiasing is however mixed. Debiasing and promoting analytical reasoning have also been criticised for their lack of pragmatism. Alternative means of increasing CR quality are therefore still needed. Because emotions are known to influence the quality of reasoning in general, we hypothesised that emotional competence (EC) could improve physicians' CR. EC refers to the ability to identify, understand, express, regulate and use emotions. The influence of EC on CR remains unclear. This article presents a scoping review protocol, the aim of which will be to describe the current state of knowledge concerning the influence of EC on physicians' CR, the type of available literature and finally the different methods used to examine the link between EC and CR. METHOD AND ANALYSIS: The population of interest is physicians and medical students. EC will be explored according to the model of Mikolajczak et al, describing five major components of EC (identify, understand, express, regulate and use emotions). The concept of CR will include terms related to its processes and outcomes. Context will include real or simulated clinical situations. The search for primary sources and reviews will be conducted in MEDLINE (via Ovid), Scopus and PsycINFO. The grey literature will be searched in the references of included articles and in OpenGrey. Study selection and data extraction will be conducted using the Covidence software. Search and inclusion results will be reported using the Preferred Reporting Items for Systematic Reviews and Meta-analyses extension for scoping review model (PRISMA-ScR). ETHICS AND DISSEMINATION: There are no ethical or safety concerns regarding this review. REGISTRATION DETAILS: OSF Registration DOI: https://doi.org/10.17605/OSF.IO/GM7YD.

Antibiotic prescribing rate after optimal near-patient C-reactive protein testing in acutely ill children presenting to ambulatory care (ARON project): protocol for a cluster-randomized pragmatic trial.

INTRODUCTION: Children become ill quite often, mainly because of infections, most of which can be managed in the community. Many children are prescribed antibiotics which contributes to antimicrobial resistance and reinforces health-seeking behaviour. Point-of-care C reactive protein (POC CRP) testing, prescription guidance and safety-netting advice can help safely reduce antibiotic prescribing to acutely ill children in ambulatory care as well as save costs at a systems level. METHODS AND ANALYSIS: The ARON (Antibiotic prescribing Rate after Optimal Near-patient testing in acutely ill children in ambulatory care) trial is a pragmatic cluster randomized controlled superiority trial with a nested process evaluation and will assess the clinical and cost effectiveness of a diagnostic algorithm, which includes a standardised clinical assessment, a POC CRP test, and safety-netting advice, in acutely ill children aged 6 months to 12 years presenting to ambulatory care. The primary outcome is antibiotic prescribing at the index consultation; secondary outcomes include clinical recovery, reconsultation, referral/admission to hospital, additional testing, mortality and patient satisfaction. We aim to recruit a total sample size of 6111 patients. All outcomes will be analysed according to the intent-to-treat approach. We will use a mixed-effect logistic regression analysis to account for the clustering at practice level. ETHICS AND DISSEMINATION: The study will be conducted in compliance with the principles of the Declaration of Helsinki (current version), the principles of Good Clinical Practice and in accordance with all applicable regulatory requirements. Ethics approval for this study was obtained on 10 November 2020 from the Ethics Committee Research of University Hospitals Leuven under reference S62005. We will ensure that the findings of the study will be disseminated to relevant stakeholders other than the scientific world including the public, healthcare providers and policy-makers. The process evaluation that is part of this trial may provide a basis for an implementation strategy. If our intervention proves to be clinically and cost-effective, it will be essential to educate physicians about introducing the diagnostic algorithm including POC CRP testing and safety-netting advice in their daily practice.

Capturing complexity in clinician case-mix: classification system development using GP and physician associate data.

BACKGROUND: There are limited case-mix classification systems for primary care settings which are applicable when considering the optimal clinical skill mix to provide services. AIM: To develop a case-mix classification system (CMCS) and test its impact on analyses of patient outcomes by clinician type, using example data from physician associates' (PAs) and GPs' consultations with same-day appointment patients. DESIGN & SETTING: Secondary analysis of controlled observational data from six general practices employing PAs and six matched practices not employing PAs in England. METHOD: Routinely-collected patient consultation records (PA n = 932, GP n = 1154) were used to design the CMCS (combining problem codes, disease register data, and free text); to describe the case-mix; and to assess impact of statistical adjustment for the CMCS on comparison of outcomes of consultations with PAs and with GPs. RESULTS: A CMCS was developed by extending a system that only classified 18.6% (213/1147) of the presenting problems in this study's data. The CMCS differentiated the presenting patient's level of need or complexity as: acute, chronic, minor problem or symptom, prevention, or process of care, applied hierarchically. Combination of patient and consultation-level measures resulted in a higher classification of acuity and complexity for 639 (30.6%) of patient cases in this sample than if using consultation level alone. The CMCS was a key adjustment in modelling the study's main outcome measure, that is rate of repeat consultation. CONCLUSION: This CMCS assisted in classifying the differences in case-mix between professions, thereby allowing fairer assessment of the potential for role substitution and task shifting in primary care, but it requires further validation.

Patients' experiences of consultations with physician associates in primary care in England: A qualitative study.

BACKGROUND: Physician associates are new to English general practice and set to expand in numbers. OBJECTIVE: To investigate the patients' perspective on consulting with physician associates in general practice. DESIGN: A qualitative study, using semi-structured interviews, with thematic analysis. SETTING AND PARTICIPANTS: Thirty volunteer patients of 430 who had consulted physician associates for a same-day appointment and had returned a satisfaction survey, in six general practices employing physician associates in England. FINDINGS: Some participants only consulted once with a physician associate and others more frequently. The conditions consulted for ranged from minor illnesses to those requiring immediate hospital admission. Understanding the role of the physician associate varied from 'certain and correct' to 'uncertain', to 'certain and incorrect', where the patient believed the physician associate to be a doctor. Most, but not all, reported positive experiences and outcomes of their consultation, with some choosing to consult the physician. Those with negative experiences described problems when the limits of the role were reached, requiring additional GP consultations or prescription delay. Trust and confidence in the physician associate was derived from trust in the NHS, the general practice and the individual physician associate. Willingness to consult a physician associate was contingent on the patient's assessment of the severity or complexity of the problem and the desire for provider continuity. CONCLUSION: Patients saw physician associates as an appropriate general practitioner substitute. Patients' experience could inform delivery redesign.

Physician Associate and General Practitioner Consultations: A Comparative Observational Video Study.

BACKGROUND: Physician associates, known internationally as physician assistants, are a mid-level practitioner, well established in the United States of America but new to the United Kingdom. A small number work in primary care under the supervision of general practitioners, where they most commonly see patients requesting same day appointments for new problems. As an adjunct to larger study, we investigated the quality of the patient consultation of physician associates in comparison to that of general practitioners. METHOD: We conducted a comparative observational study using video recordings of consultations by volunteer physician associates and general practitioners with consenting patients in single surgery sessions. Recordings were assessed by experienced general practitioners, blinded to the type of the consulting practitioner, using the Leicester Assessment Package. Assessors were asked to comment on the safety of the recorded consultations and to attempt to identify the type of practitioner. Ratings were compared across practitioner type, alongside the number of presenting complaints discussed in each consultation and the number of these which were acute, minor, or regarding a chronic condition. RESULTS: We assessed 62 consultations (41 general practitioner and 21 physician associates) from five general practitioners and four physician associates. All consultations were assessed as safe; but general practitioners were rated higher than PAs in all elements of consultation. The general practitioners were more likely than physician associates to see people with multiple presenting complaints (p<0.0001) and with chronic disease related complaints (p = 0.008). Assessors correctly identified general practitioner consultations but not physician associates. The Leicester Assessment Package had limited inter-rater and intra-rater reliability. CONCLUSIONS: The physician associate consultations were with a less complex patient group. They were judged as competent and safe, although general practitioner consultations, unsurprisingly, were rated as more competent. Physician associates offer a complementary addition to the medical workforce in general practice.

Physician associates and GPs in primary care: a comparison.

BACKGROUND: Physician associates [PAs] (also known as physician assistants) are new to the NHS and there is little evidence concerning their contribution in general practice. AIM: This study aimed to compare outcomes and costs of same-day requested consultations by PAs with those of GPs. DESIGN AND SETTING: An observational study of 2086 patient records presenting at same-day appointments in 12 general practices in England. METHOD: PA consultations were compared with those of GPs. Primary outcome was re-consultation within 14 days for the same or linked problem. Secondary outcomes were processes of care. RESULTS: There were no significant differences in the rates of re-consultation (rate ratio 1.24, 95% confidence interval [CI] = 0.86 to 1.79, P = 0.25). There were no differences in rates of diagnostic tests ordered (1.08, 95% CI = 0.89 to 1.30, P = 0.44), referrals (0.95, 95% CI = 0.63 to 1.43, P = 0.80), prescriptions issued (1.16, 95% CI = 0.87 to 1.53, P = 0.31), or patient satisfaction (1.00, 95% CI = 0.42 to 2.36, P = 0.99). Records of initial consultations of 79.2% (n = 145) of PAs and 48.3% (n = 99) of GPs were judged appropriate by independent GPs (P<0.001). The adjusted average PA consultation was 5.8 minutes longer than the GP consultation (95% CI = 2.46 to 7.1; P<0.001); cost per consultation was GBP £6.22, (US$ 10.15) lower (95% CI = -7.61 to -2.46, P<0.001). CONCLUSION: The processes and outcomes of PA and GP consultations for same-day appointment patients are similar at a lower consultation cost. PAs offer a potentially acceptable and efficient addition to the general practice workforce.

Quality of life in dementia: a systematically conducted narrative review of dementia-specific measurement scales.

OBJECTIVES: Ascertaining the quality of life (QoL) in people with dementia is important for evaluating service outcomes and cost-effectiveness. This paper identifies QoL measures for people with dementia and assesses their properties. METHOD: A systematic narrative review identified articles using dementia QoL measures. Electronic databases searched were AMED, CINAHL, EMBASE, Index to Theses, IBSS, MEDLINE, PsycINFO, Sociological Abstracts, and Web of Science. All available years and languages (if with an English language abstract) were included. RESULTS: Searches yielded 6806 citations; 3043 were multiple duplicates (759 being true duplicates). Abstracts were read; 182 full papers were selected/obtained, of which 126 were included as relevant. Few measures were based on rigorous conceptual frameworks. Some referenced Lawton's model (Dementia Quality of Life [DQOL] and Quality of Life in Alzheimer's Disease [QOL-AD]), though these tapped part of this only; others claimed relationship to a health-related QoL concept (e.g. DEMQOL), though had less social relevance; others were based on limited domains (e.g. activity, affect) or clinical opinions (Quality of Life in Late-Stage Dementia [QUALID]). Many measures were based on proxy assessments or observations of people with dementia's QoL, rather than their own ratings. The Bath Assessment of Subjective Quality of Life in Dementia (BASQID) was developed involving people with dementia and caregivers, but excluded some of their main themes. All measures were tested on selective samples only (ranging from community to hospital clinics, or subsamples/waves of existing population surveys), in a few sites. Their general applicability remains unknown, and predictive validity remains largely untested. CONCLUSION: The lack of consensus on measuring QoL in dementia suggests a need for a broader, more rigorously tested QoL measure.

'Complex' but coping: experience of symptoms of tuberculosis and health care seeking behaviours--a qualitative interview study of urban risk groups, London, UK.

BACKGROUND: Tuberculosis awareness, grounded in social cognition models of health care seeking behaviour, relies on the ability of individuals to recognise symptoms, assess their risk and access health care (passive case finding). There is scant published research into the health actions of 'hard-to-reach' groups with tuberculosis, who represent approximately 17% of the London TB caseload. This study aimed to analyse patients' knowledge of tuberculosis, their experiences of symptoms and their health care seeking behaviours. METHODS: Qualitative interviews were conducted with 17 participants, predominantly homeless and attending a major tuberculosis centre in London, UK. Most had complex medical and social needs including drug and alcohol use or immigration problems affecting entitlement to social welfare. Analytical frameworks aimed to reflect the role of broader social structures in shaping individual health actions. RESULTS: Although participants demonstrated some knowledge of tuberculosis their awareness of personal risk was low. Symptoms commonly associated with tuberculosis were either not recognised or were attributed to other causes for which participants would not ordinarily seek health care. Many accessed health care by chance and, for some, for health concerns other than tuberculosis. CONCLUSIONS: Health education, based on increasing awareness of symptoms, may play a limited role in tuberculosis care for populations with complex health and social needs. The findings support the intensification of outreach initiatives to identify groups at risk of tuberculosis and the development of structured care pathways which support people into prompt diagnosis and treatment.

Reconciling recovery, personalisation and Housing First: integrating practice and outcome in the field of multiple exclusion homelessness.

'Recovery' is a key concept in the organisation and delivery of interdisciplinary support for people experiencing multiple exclusion homelessness (MEH, that is, situations where homelessness overlaps with a range of other complex problems such as mental health issues and drug and alcohol dependencies). At the level of individual support planning, practitioners are expected to 'work together' to motivate service users to make positive changes to their lives and to secure outcomes (results) such as employment and permanent accommodation. Drawing on the accounts of 34 (n = 34) people with first-hand experience of MEH in England, we outline some of the limitations of 'recovery-orientated practices', namely the exclusion of people with unresolved needs and the implications this may have for continuity of provision. To address this issue, we argue that there is a need for a more personalised and inclusive practice model, which can accommodate 'recovery' (change outcomes) alongside those for maintenance and prevention. In proposing one such model, we show how this might also take forward the principles of 'Housing First' (a US blueprint for tackling entrenched homelessness), which has already begun to challenge the orthodox view that permanent accommodation should be provided only when recovery has been achieved.
