The Essentials: Upskilling a National Health Workforce in the Identification and Treatment of Eating Disorders.

Health practitioners report limited skills and lack of confidence in managing and treating people with eating disorders. The purpose of this study was to evaluate the national rollout of comprehensive basic training in identification, assessment, treatment, and management of people with eating disorders to clinicians. The Essentials: Training Clinicians in Eating Disorders is a core competency eLearning program. As part of a nation-wide multidisciplinary workforce training strategy, 7500 course places were provided free of charge to public and private health care professionals across all jurisdictions of Australia between January 2020 and March 2022. A total of 7370 health professionals enrolled during the study period. All learning outcomes showed improvement with large effect (Cohen's d = 1.2-2), with the largest improvements for self-reported knowledge of requirements for working with children and adolescents. Effects did not depend on years of working with eating disorders suggesting that the training was beneficial across levels of experience. Those who started with very low knowledge of eating disorders or higher willingness to treat eating disorders were most likely to complete the course. Most participants reported that the course was relevant to their clinical practice, that they expected their clinical practices to change, and that they would recommend the course to other health professionals. The strategy to provide government-funded core competency training in eating disorder care to healthcare professionals met key objectives by reaching health professionals eligible to provide government-rebated services in public and private settings across all jurisdictions including regional and remote areas.

Effective components of services for recurrent care experienced parents: A literature review of what works

Recurrent care services aim to reduce the number of repeat removals amongst birth parents who have already ‘lost’ a child through care proceedings. This literature review aimed to identify published evidence about effective components of services to support parents who have experienced repeat removals of their children to care.Searches identified 19 studies that included content relating to the components of service provision within recurrent care services. Across all studies, a range of perspectives were included: birth parents (n = 425); practitioners (n ≥ 151); other professionals (n = 109).The evidence reviewed indicates the importance of relationship-based practice, building a trusted relationship between parents and practitioners, continuity and tenacity in engaging with mothers and a non-judgemental approach. Services should be flexible, holistic and client led, with a long duration of support and a flexible end date. Services should: have a trauma-informed approach; recognise unresolved loss, complex grief and trauma experienced by mothers who have ‘lost’ their children through care proceedings; and provide emotional support, therapeutic support, practical support and advocacy. Services need to have a skilled and multi-disciplinary workforce with robust supervision and ongoing training.

Addressing closed and limited enrolments in general practices in Aotearoa New Zealand: a mixed-methods study.

To ascertain the reasons for and impacts of closed books in general practices in Aotearoa New Zealand and report recommendations for mitigation. A mixed-methods approach was used. A first round of interviews with experts in the primary care sector was conducted, followed by a survey across general practices and, finally, a second round of interviews. Data reported here are qualitative data from the interviews and open-ended questions in the survey. Qualitative data were analysed using a general inductive approach. The key reasons for not enrolling new patients included workforce shortages, high workloads and staff burnout, funding issues, concerns about quality of care and insufficient physical space. These were exacerbated during the COVID-19 pandemic. The impacts included no access or delayed access to primary care, worsening health conditions, undiagnosed or untreated diseases and less or no access to preventive care. Recommendations included recruiting more staff including administrative staff, resolving the pay disparity between general practice and hospital staff, having a longer placement period for students in general practice, utilising a multidisciplinary workforce and revising the funding formula. There is an urgent need to resolve key issues so that general practices can accept all who wish to enrol.

The health workforce conundrum for burn care in Uttar Pradesh, India: a qualitative exploration

ABSTRACT Delivering specialised care for major burns requires a multidisciplinary health workforce. While health systems ‘hardware’ issues, such as shortages of the healthcare workforce and training gaps in burn care are widely acknowledged, there is limited evidence around the systems ‘software’ aspects, such as interest, power dynamics, and relationships that impact the healthcare workforce performance. This study explored challenges faced by the health workforce in burn care to identify issues affecting their performance. Qualitative in-depth interviews were conducted with a purposively selected sample (n = 31, 18 women and 13 men) of various cadres of the burn care health workforce in Uttar Pradesh, India. Inductive coding and thematic analysis identified three major themes. First, the dynamics within the multidisciplinary team where complex relations, power and normative hierarchy hampered performance. Second, the dynamics between health workers and patients due to the clinical and emotional challenges of dealing with burn injuries and multitasking. Third, dynamics between specialised burn units and broader health systems are narrated in challenges due to inadequate first response and delayed referral from primary care facilities. These findings indicate that burn care health workers in India face multiple challenges that need systemic intervention with a multipronged human resource for health framework.

Northwestern University resource and education development initiatives to advance collaborative artificial intelligence across the learning health system.

The rapid development of artificial intelligence (AI) in healthcare has exposed the unmet need for growing a multidisciplinary workforce that can collaborate effectively in the learning health systems. Maximizing the synergy among multiple teams is critical for Collaborative AI in Healthcare. We have developed a series of data, tools, and educational resources for cultivating the next generation of multidisciplinary workforce for Collaborative AI in Healthcare. We built bulk-natural language processing pipelines to extract structured information from clinical notes and stored them in common data models. We developed multimodal AI/machine learning (ML) tools and tutorials to enrich the toolbox of the multidisciplinary workforce to analyze multimodal healthcare data. We have created a fertile ground to cross-pollinate clinicians and AI scientists and train the next generation of AI health workforce to collaborate effectively. Our work has democratized access to unstructured health information, AI/ML tools and resources for healthcare, and collaborative education resources. From 2017 to 2022, this has enabled studies in multiple clinical specialties resulting in 68 peer-reviewed publications. In 2022, our cross-discipline efforts converged and institutionalized into the Center for Collaborative AI in Healthcare. Our Collaborative AI in Healthcare initiatives has created valuable educational and practical resources. They have enabled more clinicians, scientists, and hospital administrators to successfully apply AI methods in their daily research and practice, develop closer collaborations, and advanced the institution-level learning health system.

Next steps for the psychological workforce in NHS Scotland

Glasgow Kelvingrove MuseumIn recent years very significant progress in expanding the Scottish NHS psychology and psychological therapies workforce has been achieved. This has been because of additional investment to increase training places in clinical psychology and the development of newer psychology roles, alongside upskilling the wider multidisciplinary and multi-sectoral workforce in psychological care. The influence and profile of psychology has never been higher. The rapid and flexible response of psychologists during the pandemic in adapting the delivery of clinical services and responding to the psychological needs of the workforce helped establish the profession as a valued partner in joint problem solving for service and policy leaders. The appointment of a Psychology Advisor to Scottish Government and the publication of the new Mental Health Strategy, along with the updated Matrix Guidance for the delivery of Psychological Therapies, and the revised Psychological Therapies access standard all show the growing influence of psychology. To build on this progress psychologists need to embrace their roles in clinical leadership but also in thinking about whole system design to improve access to evidence based psychological therapies and interventions for our population. This will include continuing to support the development of multidisciplinary approaches to the delivery of psychological practice, developing new roles and extended roles through involvement with training, supervision and governance. Ensuring effective collaboration with people with lived experience will be a key action along with continuing to develop the evidence base. Supporting the development of national data reporting systems including outcome measures will help drive further improvement.

Bad behavior in healthcare: an insidious threat to patients, staff, and organizations.

'Bad' or unprofessional behavior (UPB) destroys communication, teamwork, and professional wellbeing, presenting a significant threat to patients and staff. Understanding what constitutes 'bad' or UPB and creating broad accountability for its cessation is imperative to patient-centered care and the survival of the multidisciplinary health workforce. Despite organizational and legislative commitments to provide well tolerated work environments, UPB is endemic in healthcare and continues to harm patients, staff, and organizations. Historically, categories of UPB have been researched separately which dilutes the problem. Typically, these behaviors cluster, are interchangeable, and are committed by same perpetrators. Women, junior staff, and minority groups remain the most prevalent targets. Even low intensity UPBs among health staff dramatically impacts risk to patient lives, limits quality care, and destroys staff wellbeing. Targeted interventions must address all five roles impacted by UPBs: the target, patients, bystanders, the perpetrator, and the organization to effectively eliminate UPBs. Organizational leaders must demonstrate and uphold organizational values and be swift in addressing UPB to limit the impact on teams and patients. UPB in the healthcare setting presents a multifactorial threat to patients, staff, and organizations. To ensure the delivery of high-quality patient care, and the wellbeing of the health workforce it is crucial to understand the insidious impact of UPB and target interventions across all five roles.

Facilitators and Barriers of Implementation of Evidence-Based Parenting Support in Educational Settings

Improving child behavior and promoting family well-being is a key objective of evidence-based parenting programs, such as the Triple P–Positive Parenting Program. To achieve this goal, parenting programs are delivered using a multidisciplinary workforce. Previous researchers have collectively examined the entire workforce of parenting practitioners to determine the factors that influence program delivery, primarily using self-report measures. However, these findings did not highlight the unique factors relevant to specific practitioner disciplines. Educators are one practitioner discipline that play an integral role in delivering parenting programs through schools and early childhood learning settings. This study aimed at exploring the facilitators and barriers that impact frequency of program use for educator practitioners using both qualitative and quantitative analyses. Data from 404 Triple P educator practitioners were extracted from a larger dataset of 1202 practitioners from English-speaking countries who completed self-report questionnaires and responded to three open-ended questions. Hierarchical multiple regressions were conducted using eight independent variables (with participant characteristics as control variables), revealing seven positive and one negative predictor for frequency of use. A thematic analysis was then conducted on the qualitative responses, producing 11 themes and 28 subthemes. The quantitative analysis revealed organisational support, perceived usefulness, and practitioner self-regulation were the most important positive predictors. The qualitative analysis supported these findings and revealed novel barriers including Covid-19/work from home, online delivery, parent factors, and specific organisational factors. These findings highlight the need for online resources, reliable virtual delivery methods, improved ways to reach and engage families, and additional trained education practitioners to distribute high workloads.

Review of best practices of integrated care for people living with Motor Neurone Disease

Introduction: Motor neurone disease is a life limiting progressive neurological condition that requires a team-based approach to care. Person-centred care (PCC), integrated care and access to specialised motor neurone disease (MND) multidisciplinary clinics (MDC) are optimal approaches to the delivery of quality service for people living with MND (plwMND) for improved quality of life, health outcomes and care experiences. These MND MDCs models of care vary in design, implementation, and are predominantly specialist hospital based. Therefore, not all MND services are delivered consistently highlighting a need to explore the evidence on current practices that contribute to more effective, efficient person-centred integrated care practices across the continuum.
 Aim: This rapid review explores best practices of integrated care for people living with motor neurone disease, and their families and carers.
 Methods: A search was undertaken of six databases, Medline (Ovid), Embase (Ovid), CINAHL, Cochrane, Joanna Briggs Institute and Google Scholar. The 1469 retrieved abstracts were screened for eligibility against the inclusion criteria, and full text review was conducted on 149 studies. Data were extracted from 58 studies and a quality assessment conducted on final 45 included studies. The following information was gathered from the included studies to inform the review.
 1.What is ‘best practice’ in the management/care of plwMND
 2.What models of (integrated) care have been developed to support plwMND
 3.What are the common elements of integrated care approaches that have been implemented in MND?
 4.What impacts, outcomes, or effects of integrated care approaches have been reported for plwMND?
 
 Results: The initial review analysis indicated specialised MND multidisciplinary clinics (MDC) as ‘best practice’ in the optimal management of MND, but revealed no standardised approaches in design and implementation, the multidisciplinary workforce, and degree of integration and partnerships between hospitals and the community. MND MDC are predominantly hospital based, but the inclusion of either outreach community teams, hub and spoke approaches, and/or a hybrid design, (care delivered in person and /or by telehealth), improved integration, knowledge sharing and coordination across services. The timing of introduction and delivery of palliative care services differs but there is greater focus on integration into MND MDC, or earlier referrals to dedicated palliative care service and/or specific palliative care training of neurologist/multidisciplinary team, to optimise symptom management, decision-making and end of life care. Additional features that enable integration, improve care satisfaction and equity are one or a mix of 1) telehealth, 2) care coordination, 3) case management, 4) partnerships with MND associations, and/or 5) MND helpline.
 Conclusion: This review highlights a range of practices of integrated care that are not universal and predominantly practiced in high income countries. Adapting delivery of model of care to stage and duration of MND, and differing expectations, needs and priorities of plwMND and caregivers, is a common theme throughout. There has been greater uptake in telehealth and technology to support the equitable delivery of integrated approaches to care, with rapid development in this area during COVID 19 pandemic.
 

Public Health Management Cadre in India: Challenges and Road Ahead

The efforts of developing the health workforce cadres in India have been advocated for a long time. The Government of India released the booklet on implementing the Public Health Management Cadre (PHMC) as envisaged under National Health Policy 2017 was certainly a catalyst for the country. This commentary reviews the course of implementing public health cadre in India and the challenges in establishing the core principles of a Multidisciplinary health workforce. The paper suggests that the proposed cadre needs a swift implementation in the States/UTs to address the impediments to health systems in the country.

Development and pilot testing of the 2019 Canadian Abortion Provider Survey

BackgroundSubstantial changes in abortion care regulations, available medications and national clinical practice guidelines have occurred since a 2012 national Canadian Abortion Provider Survey (CAPS). We developed and piloted the CAPS 2019 survey instrument to explore changes of the abortion provider workforce, their clinical care as well as experiences with stigma and harassment.MethodsWe undertook development and piloting in three phases: (1) development of the preliminary survey sections and questions based on the 2012 survey instrument, (2) content validation and feasibility of including certain content aspects via a modified Delphi Method with panels of clinical and research experts, and (3) pilot testing of the draft survey for face validity and clarity of language; assessing usability of the web-based Research Electronic Data Capture platform including the feasibility of complex skip pattern functionality. We performed content analysis of phase 2 results and used a general inductive approach to identify necessary survey modifications.ResultsIn phase 1, we generated a survey draft that reflected the changes in Canadian abortion care regulations and guidelines and included questions for clinicians and administrators providing first and second trimester surgical and medical abortion. In phase 2, we held 6 expert panel meetings of 5–8 participants each representing clinicians, administrators and researchers to provide feedback on the initial survey draft. Due to the complexity of certain identified aspects, such as interdisciplinary collaboration and interprovincial care delivery differences, we revised the survey sections through an iterative process of meetings and revisions until we reached consensus on constructs and questions to include versus exclude for not being feasible. In phase 3, we made minor revisions based on pilot testing of the bilingual, web-based survey among additional experts chosen to be widely representative of the study population. Demonstrating its feasibility, we included complex branching and skip pattern logic so each respondent only viewed applicable questions based on their prior responses.ConclusionsWe developed and piloted the CAPS 2019 survey instrument suitable to explore characteristics of a complex multidisciplinary workforce, their care and experience with stigma on a national level, and that can be adapted to other countries.

Building the foundation for a community-generated national research blueprint for inherited bleeding disorders: facilitating research through infrastructure, workforce, resources and funding

ABSTRACT Background The National Hemophilia Foundation (NHF) conducted extensive, inclusive community consultations to guide prioritization of research in coming decades in alignment with its mission to find cures and address and prevent complications enabling people and families with blood disorders to thrive. Research Design and Methods With the American Thrombosis and Hemostasis Network, NHF recruited multidisciplinary expert working groups (WG) to distill the community-identified priorities into concrete research questions and score their feasibility, impact, and risk. WG6 was charged with identifying the infrastructure, workforce development, and funding and resources to facilitate the prioritized research. Community input on conclusions was gathered at the NHF State of the Science Research Summit. Results WG6 detailed a minimal research capacity infrastructure threshold, and opportunities to enable its attainment, for bleeding disorders centers to participate in prospective, multicenter national registries. They identified challenges and opportunities to recruit, retain, and train the diverse multidisciplinary care and research workforce required into the future. Innovative collaborative approaches to trial design, resource networking, and funding to surmount obstacles facing research in rare disorders were elucidated. Conclusions The innovations in infrastructure, workforce development, and resources and funding proposed herein may contribute to facilitating a National Research Blueprint for Inherited Bleeding Disorders.

Key factors influencing public health students and curricula in India: Recommendations from a mixed methods analysis.

Building on a distinguished history of community medicine training, public health programs have been expanding in India in recent years. The COVID-19 pandemic has brought additional attention to the importance of public health programs and the need for a strong workforce. This paper aims to assess the current capacity for public health education and training in India and provide recommendations for improved approaches to meet current and future public health needs. We conducted a desk review of public health training programs via extensive internet searches, literature reviews, and expert faculty consultations. Among those programs, we purposively selected faculty members to participate in in-depth interviews. We developed summary statistics based on the desk review. For qualitative analysis, we utilized a combination of deductive and inductive coding to identify key themes and systematically reviewed the strengths and weaknesses of each theme. The desk review captured 59 institutions offering public health training across India. The majority of training programs were graduate level degrees including Master of Public Health and Master of Science degrees. Key factors impacting these programs included collaborations, mentorship, curriculum standardization, tuition and funding, and student demand for public health education and careers. Collaborations and mentorship were highly valued but varied in quality across institutions. Curricula lacked standardization but also contained substantial flexibility and innovation as a result. Public sector programs were perceived to be affordable though fees and stipends varied across institutions. Further development of career opportunities in public health is needed. Public health education and training in India have a strong foothold. There are numerous opportunities for continued expansion and strengthening of this field, to support a robust multi-disciplinary public health workforce that will contribute towards achieving the sustainable development goals.

Strategies to improve healthcare services for patients with sickle cell disease in Nigeria: The perspectives of stakeholders.

Background: Sickle cell disease (SCD) continues to pose physical and psychosocial burdens to patients, caregivers and health workers. Stakeholder engagement in the processes of policy making and implementation is increasingly becoming the cornerstone of best practices in healthcare. Aim and Objectives: To engage stakeholders with a view to assessing the knowledge of SCD; ascertain the challenges associated with accessibility and affordability of healthcare services; improve the quality of care, and thereby effect behavioral change through increasing attendance and follow-up of patients in the clinics. Methodology: A Stakeholders' Engagement meeting organized by the Sickle Pan Africa Research Consortium Nigeria Network (SPARC-NEt) was attended by patients, caregivers and members of patient support groups, healthcare providers and management/policymakers. The engagement was through PowerPoint presentations, structured questionnaires and an interactive session. The structured questionnaire assessed the knowledge of stakeholders about SCD; the quality of healthcare services; challenges with access and affordability; and SCD-related government policies. Results: Three hundred and twelve stakeholders attended the engagement meeting. Of the 133 that participated in the study, medical workers were the most represented. The majority had good knowledge of what causes SCD (96.2%) and the best place to get help during SCD crisis (98.5%). However, knowledge of the specific preventive measures of SCD and its crisis was not optimal. In terms of the role of community engagement and education, only about one-quarter of the study participants, 34 (25.6%) knew about their positive role in reducing the prevalence of SCD and alleviating SCD crises. Challenges identified include inadequate healthcare personnel and facilities, delay in obtaining laboratory results, long waiting time in the clinic, poor communication, absence of holistic consultation, uncoordinated healthcare services, high cost of care, ignorance, non-prioritization of SCD by government, lack of multisectoral collaboration and partnership with NGOs and international organizations. Strategies proffered to improve healthcare services include, community/stakeholder engagement and health education, sickle cell daycare services, access to a willing and dedicated multidisciplinary workforce, collaboration with support groups and government policies and programs. Conclusion: There is need for regular stakeholder engagement to improve access to healthcare services for SCD patients in Nigeria.

An Exploratory Evaluation of the Impact and Acceptability of a Structured Reflective Practice Program Piloted with Staff in a Forensic Mental Health Setting

This study describes and examines the impact of a novel Reflective Practice program tailored to the multidisciplinary clinical workforce at an inpatient forensic mental health setting. Surveys assessing wellbeing, self-efficacy and reflective practice capacity were administered to all clinical staff prior to commencement of the Reflective Practice program, as well as six months post-implementation. Interviews were also conducted with key clinical stakeholders to obtain detailed feedback regarding the impact of the program across the organization following six-eight months of implementation. Staff who participated in post-implementation surveys reported significantly higher confidence in their work when compared to staff at baseline, while clinical stakeholders observed improvements in the cohesion of the multidisciplinary team. In spite of the limitations of the pragmatic study design and small sample size, results suggest the novel Reflective Practice program offers an acceptable model for adoption in an inpatient forensic mental health setting, with potential to improve the wellbeing, learning and morale of a forensic mental health workforce. The findings also highlight the need to support practice development and wellbeing in early career clinicians, where low confidence and high stress are predominant.

TOWARDS INTEGRATING REHABILITATION INTO HEALTH SYSTEMS THROUGH PROFESSIONAL REGULATION

Strengthening rehabilitation in health systems and integrating rehabilitation across all levels of care depends on a mix of strategies, however all depend on an appropriately trained, resourced and organized workforce. Indeed, among the ten areas for action described in the World Health Organization 2030 initiative is developing a strong multidisciplinary rehabilitation workforce that is suitable for country context, and promoting rehabilitation concepts across all health workforce education. The rehabilitation workforce is constantly evolving as it strives to provide safe practices and treatment choices based on the best available evidence to improve function, promote independence and help people reach their maximum potential. However, barriers to this evolution include a lack of well-resourced training programs, variations in the competencies expected within the standard entry-level curriculum, limited opportunities for continuing professional development, geopolitical instability, competing demands for limited health budgets and persistent de-prioritization of rehabilitation.

An analysis of human resource practices: A comparison between the hospitality industry and other sectors

The success of public and private sector organizations is largely determined by the knowledge, skills, and motivation of their workforce. The private sector currently dominates the provision of services, accounting for 70% of services provided. Within the private sector, the hospitality industry is particularly dependent on a multidisciplinary workforce with various categories of employees. Supervisory staff, middle management, and senior executives all play crucial roles in ensuring the provision of high-quality hospitality services. Effective personnel management is essential to ensure that the qualitative and quantitative needs of different departments are met. However, the hospitality industry operates in a dynamic and complex environment, which can lead to challenges such as lower occupancy rates, higher capacity, shorter guest stays, and negative impacts on the hotel's reputation. Therefore, the quality of care provided to guests is of utmost importance in the hospitality industry, as it can directly affect business growth and performance. Adequate guest care and preferences must be taken into account, and strategies should be in place to ensure that the hospitality services meet guests' needs and preferences.

Creating a robust multidisciplinary public health workforce - almost there?

From 1972 to 2001, membership of the Faculty of Public Health (FPH) was only open to medical practitioners with recognised specialist experience or training in public health. In 2001, the Faculty became multidisciplinary at the specialist level, a rare achievement in a medical specialty in the UK. 1 Specialists from backgrounds other than medicine were accepted as Members and Fellows of the Faculty provided they met the required standards. They were eligible for Consultant and Director of Public Health (DPH) posts, initially in England and Wales. A multidisciplinary higher specialist training scheme was established and, over time, rolled out systematically across the UK. These changes later led to limited developments for public health practitioners filling roles distinct from those in the specialist workforce. Reviewing this history reminds current and future generations of the struggles to reach the unique model we have today. The article teases out the key factors leading to the changes, summarises the somewhat bumpy journey over five decades and, in the shadow of the pandemic, reflects on the contemporary situation for the UK's public health workforce.

The Faculty of Public Health: past, present and future.

This year we celebrate 50 years of the UK Faculty of Public Health (FPH). This commentary serves as a reflection on the history of the FPH, considering the origins of public health in the UK and the role of the FPH in shaping public health practice and policy. The genesis and evolution of the FPH are discussed, drawing upon reflections from past presidents and the wider literature. Historical shifts in the identity and roles of public health practitioners are also explored in the context of an increasingly complex and dynamic health and social care system. Key changes in public health practice are described, including the development of a multidisciplinary public health workforce and an increased focus on health inequalities over recent decades. Building upon this is a discussion of the current purpose of the FPH and perspectives on the future of the FPH amidst a changing public health landscape.

Building a trauma-informed national mental health workforce: Learning outcomes from use of the core curriculum on childhood trauma in multidisciplinary practice settings.

The impact of trauma on mental and physical health has long been recognized as a significant public health issue, yet there has been little unanimity about how to best develop a trauma-capable national workforce. The Core Curriculum on Childhood Trauma (CCCT) is being used to train a wide variety of mental health professionals and child-serving staff; however, prior data on its effectiveness have been limited to small pilot studies with master's in social work students. We used 1,908 retrospective pre-post-training evaluations collected from 168 CCCT trainings delivered in multidisciplinary or practice settings between October 2016 and August 2019. CCCT participants reported high levels of satisfaction and statistically significant change between pre- and postscores for 8 self-reported child trauma skills (p < .001), with effect sizes ranging from .78 to 1.45. The consistency of positive outcomes across a wide variety of training formats and audiences demonstrates that the CCCT can be implemented successfully in diverse practice settings and thus can be a useful tool for building a trauma-capable, multidisciplinary national mental health workforce.
