The ‘expert’ in problem‐based and case‐based learning: necessary or not?

BACKGROUND: Problem-based learning (PBL) and other small-group teaching methods which incorporate principles of adult learning, are exciting innovations in medical education. In the application of these methods to medical curricula many schools have introduced non-expert tutors. However, research evaluating the effectiveness of non-expert lead teaching has been inconclusive. AIM: The present study aim was to compare the outcome of teaching in small groups facilitated by either an 'expert' or a 'non-expert' tutor, in a single topic area. METHOD: Fourth-year medical students were allocated randomly to teaching of eating disorders either by a non-expert or an expert tutor. Outcomes were evaluated by (i) a knowledge test, and (ii) self-report ratings by tutors and students of their learning methods and other qualities. RESULTS: The study found that while the non-expert tutor was rated more highly for her group management skills, and she also rated her students more highly in the area of oral communication, students who were taught by the expert scored higher in the end-of-course test in the topic area. CONCLUSION: The findings suggest that caution should be exercised, and the need for more research before widespread adoption of teaching by non-expert tutors.     

Embodiment without bodies? Analysis of embodiment in US‐based pro‐breastfeeding and anti‐male circumcision movements

This article uses the cases of pro‐breastfeeding and anti‐circumcision activism to complicate the prevailing conceptualisation of embodiment in research on embodied health movements (EHMs). Whereas most EHM activists draw on their own bodily experiences, in the breastfeeding and circumcision movements, embodiment by proxy is common. Activists use embodiment as a strategy but draw on physical sensations that they imagine for other people's bodies, rather than on those they experience themselves. Pro‐breastfeeding activists, who seldom disclose whether they were themselves breastfed, target mothers, encouraging them to breastfeed rather than to formula feed their children in order to reduce their child's risk of disease. Anti‐circumcision activists, only some of whom are circumcised men, urge parents to leave their sons' penises intact in order to avoid illness and disfigurement and to preserve the sons' rights to make their own informed decisions as adults. In both movements activists use embodiment as a persuasive strategy even though they themselves do not necessarily embody the risks of the negative health outcomes with which they are concerned. Future research on EHMs should reconceptualise EHMs to include embodiment by proxy and examine whether this important phenomenon systematically affects movement strategies and outcomes.     

How to regress and predict in a Bland–Altman plot? Review and contribution based on tolerance intervals and correlated‐errors‐in‐variables models

Two main methodologies for assessing equivalence in method‐comparison studies are presented separately in the literature. The first one is the well‐known and widely applied Bland–Altman approach with its agreement intervals, where two methods are considered interchangeable if their differences are not clinically significant. The second approach is based on errors‐in‐variables regression in a classical (X,Y) plot and focuses on confidence intervals, whereby two methods are considered equivalent when providing similar measures notwithstanding the random measurement errors. This paper reconciles these two methodologies and shows their similarities and differences using both real data and simulations. A new consistent correlated‐errors‐in‐variables regression is introduced as the errors are shown to be correlated in the Bland–Altman plot. Indeed, the coverage probabilities collapse and the biases soar when this correlation is ignored. Novel tolerance intervals are compared with agreement intervals with or without replicated data, and novel predictive intervals are introduced to predict a single measure in an (X,Y) plot or in a Bland–Atman plot with excellent coverage probabilities. We conclude that the (correlated)‐errors‐in‐variables regressions should not be avoided in method comparison studies, although the Bland–Altman approach is usually applied to avert their complexity. We argue that tolerance or predictive intervals are better alternatives than agreement intervals, and we provide guidelines for practitioners regarding method comparison studies.

Performance‐based contracting in home‐care work in The Netherlands: professionalism under pressure?

Our aim was to improve the understanding of the relationships between performance‐based contracting, management supportiveness and professionalism in home care. Using path analysis, this article explores the relationships between home‐care workers' perceptions of management support, implementation of performance‐based contracting (i.e. use of strict time registration rules and cost‐efficiency measures) and autonomy and intrinsic job satisfaction. We hypothesised that: use of strict time registration rules and cost‐efficiency measures relates to lower levels of autonomy and intrinsic job satisfaction (H1); there is an indirect relationship between use of strict time registration rules and use of cost‐efficiency measures and intrinsic job satisfaction via autonomy (H2); higher levels of management support relate to the use of looser time registration rules and less use of cost‐efficiency measures (H3); and higher levels of management support relate to higher levels of autonomy and intrinsic job satisfaction (H4). We used data from a cross‐sectional survey conducted in 2010 of a sample of Dutch home‐care workers (N = 156, response rate = 34%). Overall, our study suggests that the consequences of performance‐based contracting for professionalism are ambiguous. More specifically, using strict time registration rules is related to lower levels of autonomy, whereas using cost‐efficiency measures does not seem to affect autonomy (H1). Performance‐based contracting has no consequences for the level of fulfilment home‐care workers find in their job, as neither of the two contracting dimensions measured was directly or indirectly related to intrinsic job satisfaction (H1, H2). The role of managers must be taken into account when studying performance‐based contracting, because perceived higher management support is related to managers' less frequent use of both strict time registration rules and of cost‐efficiency measures (H3). The insight we gained into the importance of supportive managers for both autonomy and job satisfaction (H4) can help home‐care organisations improve the attractiveness of home‐care work.     

Evidence‐based practice?

In 1948, the world of health and medical research changed forever with the publication of the Medical Research Council's randomised controlled trial (RCT) on the use of streptomycin in the treatment of tuberculosis (TB).1,2 In that year, there were 341 papers on Streptomycin and TB published in the medical literature, but only one RCT, and this was the paper that defined a generation of TB treatment. The process of undertaking RCTs was quickly developed to include health promotion.     

Performance‐based financing in the heath sector in low‐ and middle‐income countries: Is there anything whereof it may be said,see, this is new?

Whereas performance‐based financing (PBF) is now developing fast in the health sector in low‐ and middle‐income countries and is presented an innovative approach—concomitantly, subject to a separate research stream—it shares many features of the “managing for results” (MfR) and performance‐based budgeting (PBB) currents that have existed for decades. In this paper, we first argue that PBF as currently developed in the health sector in low‐ and middle‐income countries shares many features and thus can be viewed as an avatar of MfR and more precisely PBB. Secondly, we draw lessons from the literature on MfR and PBB so as to (1) better apprehend PBF conceptually and (2) avoid pitfalls and better design PBF schemes in practice. We argue that the lessons from the theoretical and empirical literature on MfR and PBB offer interesting insights to feed into a “theory of change” of PBF, enabling to analyse critical aspects and better design PBF schemes. Moreover, it is hoped that just like MfR processes have been demonstrated as having the potential to boost individual performance not only through links with financial incentives but also through acting on other sources of motivation, one can demonstrate more accurately by which mechanisms the various elements of the PBF package can help improve health sector results.     

The role of family carers in the use of personal budgets by people with mental health problems

Personal budgets aim to increase choice and independence for people with social care needs but they remain underused by people with mental health problems compared to other disability groups. The use of personal budgets may impact on families in a variety of ways, both positive and negative. This paper draws on interviews, undertaken in 2012–2013 with 18 family carers and 12 mental health service users, that explored experiences of family involvement in accessing and managing personal budgets for a person with mental health‐related social care needs. The sample was drawn from three sites across England, with additional carers being recruited via voluntary sector networks. Our findings show that for many people with severe mental health needs who lack motivation and confidence to negotiate access to personal budgets, carers may provide the necessary support to enable them to benefit from this form of social care support. We illustrate the role carers may play in initiating, pursuing and maximising the level of support available through personal budgets. However, some carers interviewed considered that personal budget funding was reduced because of practitioners’ assumptions about carers’ willingness and ability to provide support. We also report perceived tensions between family carers and practitioners around appropriate involvement in decision‐making. The study findings have implications for local authorities, practitioners and family carers in supporting the involvement of family carers in support for people with severe mental health problems.     

Enhancing primary care support for informal carers: A scoping study with professional stakeholders

Informal carers (i.e. people who provide unpaid care to family and/or friends) are crucial in supporting people with long‐term conditions. Caring negatively impacts on carers’ health and experiences of health services. Internationally and nationally, policies, legislation, professional guidance and research advocate for health and care services to do more to support carers. This study explored the views of health and social care providers, commissioners and policy makers about the role and scope for strengthening health service support for carers. Twenty‐four semi‐structured interviews, with 25 participants were conducted, audio‐recorded, transcribed verbatim and analysed by thematic analysis. Three main themes emerged: (a) identifying carers, (b) carer support, and (c) assessing and addressing carer needs. Primary care, and other services, were seen as not doing enough for carers but having an important role in identifying and supporting carers. Two issues with carer identification were described, first people not self‐identifying as carers and second most services not being proactive in identifying carers. Participants thought that carer needs should be supported by primary care in collaboration with other health services, social care and the voluntary sector. Concerns were raised about primary care, which is under enormous strain, being asked to take on yet another task. There was a clear message that it was only useful to involve primary care in identifying carers and their needs, if benefit could be achieved through direct benefits such as better provision of support to the carer or indirect benefit such as better recognition of the carer role. This study highlights that more could be done to address carers’ needs through primary care in close collaboration with other health and care services. The findings indicate the need for pilots and experiments to develop the evidence base. Given the crucial importance of carers, such studies should be a high priority.     

Paediatric spinal fusion surgery and the transition to home‐based care: provider expectations and carer experiences

There are more than 12 million children with special healthcare needs (CSHCNs) in the United States, many of whom require specialised health‐care to treat chronic physical and developmental conditions. This study is a qualitative investigation of programme, surgical and at‐home recovery experiences among CSHCNs and their family carers who participated in a spine surgical care programme at a paediatric hospital in the Western United States. The programme is designed to manage increased surgical risk and the transition of care from hospital to home for children with severe scoliosis undergoing spinal fusion surgery. We conducted 30 semi‐structured in‐depth interviews with 14 surgical team members and 16 family carers of children who had programme evaluations and spinal surgeries in 2006. Data were collected in 2008 and 2009 in hospital or at home locations to gather programme participation feedback from families and inform the adequacy of programme support to families during at‐home recovery. Data were analysed by reflexive team and content analysis methodologies. Results showed the programme was effective at improving preoperative surgical evaluation and helping families to anticipate some aspects of the surgical experience and hospital discharge. However, the impact of spinal fusion surgery and the subsequent transition to home‐based care was profoundly emotional for patients and their carers. Our data indicate that programme providers underestimated the extent of emotional trauma experienced by patients and families, particularly during the at‐home recovery process. The data also suggest meaningful differences in providers' and carers' expectations for surgery. Carers' disappointment with their recovery experiences and the perceived lack of post‐discharge support impacted their interpretations of and perspectives on their surgical experience. Implications of this research for surgical care programmes include the need for assessment and provision of support for physical, social, and emotional burdens experienced by patients and carers at pre‐surgical, surgical and at‐home recovery phases.     

Stratified,precision or personalised medicine? Cancer services in the ‘real world’ of a London hospital

We conducted ethnographic research in collaboration with a large, research‐intensive London breast cancer service in 2013–2014 so as to understand the practices and potential effects of stratified medicine. Stratified medicine is often seen as a synonym for both personalised and precision medicine but these three terms, we found, also related to distinct facets of treatment and care. Personalised medicine is the term adopted for the developing 2016 NHS England Strategy, in which breast cancer care is considered a prime example of improved biological precision and better patient outcomes. We asked how this biologically stratified medicine affected wider relations of care and treatment. We interviewed formally 33 patients and 23 of their carers, including healthcare workers; attended meetings associated with service improvements, medical decision‐making, public engagement, and scientific developments as well as following patients through waiting rooms, clinical consultations and other settings. We found that the translation of new protocols based on biological research introduced further complications into an already‐complex patient pathway. Combinations of new and historic forms of stratification had an impact on almost all patients, carers and staff, resulting in care that often felt less rather than more personal.     

The use of boundary objects to enhance interprofessional collaboration: integrating complementary medicine in a hospital setting

Because of the inherent complexity of human health, the provision of good quality patient care requires collaboration in multidisciplinary teams. Integrative healthcare provides a unique setting for the study of interprofessional collaboration in the context of power disparities. The research objective was to examine which means and mechanisms were used to facilitate interprofessional collaboration when integrating complementary medicine (CM) into a hospital’s surgical department. Throughout 2010 we conducted a qualitative study in an Israeli public hospital’s surgical department, using observations and 30 in‐depth interviews with managers, surgeons, physicians, nurses, patients and CM practitioners. The sociological concepts of boundary actor and boundary object and the context of power relations served as a framework for this research. This article contributes to the field of interprofessional collaborative care research by: analysing types of collaboration inhibitors – epistemological and social‐structural gaps; pointing to boundary actors who establish interprofessional collaboration in an integrative hospital setting and noting the boundary objects they use; and comparing collaboration levels. The collaboration between CM practitioners and the department’s staff is a loosely coupled system. When coordination was achieved, reaching profound agreements seemed of lesser importance to the parties. Closer collaboration and cross‐fertilisation were found among CM practitioners.     

Codesigned recommendations for increasing engagement in structured physical activity for people with serious mental health problems in Australia

People with mental health problems are at higher risk of physical health comorbidities and early mortality. A key risk factor for poor health outcomes is a lack of regular physical activity. Mental health services have typically responded by focusing on screening and promoting lifestyle programmes within secondary care mental health settings. The aim of this study was to better understand the barriers and enablers for Australian mental health consumers to participate in physical activity or exercise programmes from the perspectives of consumers and exercise practitioners. Interviews with 15 consumers experiencing serious mental health problems and five exercise practitioners were undertaken, followed by two focus groups (involving eight consumers and two exercise practitioners) to gain consensus on themes from the interviews, and codesign a set of recommendations for services to support and increase the engagement of mental health consumers in regular community‐based exercise. Barriers that impacted on engagement in physical activity included: lack of social support, insufficient knowledge and information, difficulties with work/life balance, impact of physical and mental health issues, fear and lack of confidence, and financial cost. Enablers or motivators assisting engagement in community‐based physical activity programmes included: social support, access to person‐centred individualised exercise options, connection and a sense of belonging, and access to information and education. Recommendations and a checklist were developed to assist services to increase the involvement of mental health consumers in community‐based exercise and to ensure that exercise practitioners and their employing organisations are adequately equipped to work with this population.     

The UCLan community engagement and service user support (Comensus) project: valuing authenticity, making space for emergence

OBJECTIVE: To develop and evaluate service user, carer and community involvement in health and social care education. BACKGROUND: Despite the high policy profile of involvement issues, there appear to be no published accounts of schemes that have used a systematic whole-faculty approach to community engagement in health and social care higher education. FOCUS OF THIS PAPER: The set up and early development of a faculty-wide community engagement project. SETTING AND PARTICIPANTS: Staff from the faculty of health in one University, local service users and carers and community group project workers and local National Health Service (NHS) and public sector staff. DESIGN: Participatory action research including document review, field notes, questionnaires and interviews. ANALYSIS: Thematic analysis. The emerging themes were tested by seeking disconfirming data, and through verification with stake-holders. RESULTS: Prior to the study, there were examples of community engagement in the participating faculty, but they occurred in specific departments, and scored low on the 'ladder of involvement'. Some previous attempts at engagement were perceived to have failed, resulting in resistance from staff and the community. Despite this, an advisory group was successfully formed, and project framing and development evolved with all stake-holders over the subsequent year. The four themes identified in this phase were: building accessibility; being 'proper' service users/carers;moving from suspicion to trust: mutually respectful partnerships as a basis for sustainable change; and responses to challenge and emergence. CONCLUSIONS: Successful and sustainable engagement requires authenticity. Many problems and solutions arising from authentic engagement are emergent, and potentially challenging to organizations.     

Oral health problems and support as experienced by people with severe mental illness living in community‐based subsidised housing – a qualitative study

The purpose of this study was to explore how persons with severe mental illness (SMI) experience oral health problems (especially dry mouth), and weigh the support they received in this regard from professionals and staff at community‐based congregate housing through a controlled intervention programme. Oral health problems and dry mouth are found in association with apathy and indifference, cognitive deficits, and long‐term medication with psycho‐pharmacological drugs. The present study describes the results from one part of a longitudinal intervention programme, which sought effective ways of mitigating dry mouth through increased support with oral health problems. This part consists of 67 informal interviews with ten participants in two community‐based urban housing projects between November 2006 and June 2007, with a follow‐up session in December 2007. Content analysis of the results yielded five categories: The shame of having poor dental health, history of dental care, experiences of self‐care, handling of oral health problems, and experiences of staff support. Poor oral health caused shame and limited participation in social activities. Participants avoided oral health issues by such circumventions as denial of a tooth ache or dental infections, or postponing oral problems with the hope that they would die away. Offers of support were frequently resisted because of unsatisfactory prior encounters with dental professionals and staff. Our findings suggest that self‐care needs to be facilitated in an unobtrusive manner with minimal staff involvement, and clients should be referred to dental care providers experienced in treating people with SMI.
