Attenuated psychosis symptoms are related to working alliance between therapist and service user

AIM

Many trials have demonstrated the efficacy of specific therapy modalities for individuals with attenuated psychosis symptoms (APS). Less is known regarding mechanisms behind positive outcomes, including the role of nonspecific therapeutic factors. This study explored working alliance (WA) in a clinic serving individuals with APS to see how WA changed across the course of treatment and its relation to APS.

METHODS

Session level APS and WA data was available for 12 individuals of diverse racial and gender identity, (M = 48 sessions each). Multilevel models with random intercepts tested change in WA and APS over time, and cross-sectional and prospective relations.

RESULTS

WA increased and APS decreased over time. Cross sectionally, WA and APS were inversely related. Prospective relations were non-significant.

CONCLUSION

When symptoms increase, therapists for individuals with APS should be attentive to potential disruptions in WA, though strong WA may be a cross-sectional protective factor.

Drug-related deaths at Australian music festivals

BACKGROUND

Illicit drug use is overrepresented in music festival attendees compared with the general population. Drug use often involves a wide range of substances with the potential to cause drug toxicity. Law enforcement-centred strategies intended to deter drug use and supply at these mass gatherings have been implemented throughout Australia. However, many have been criticised for their lack of effectiveness, with evidence suggesting that they can inadvertently increase the risk of drug harm. Drug deaths are often multifactorial, providing added challenges in the development of prevention strategies. This study aimed to determine the frequency of deaths involving alcohol and other drugs at music festivals in Australia and to identify potential risk factors that may inform future harm reduction strategies.

METHODS

A descriptive case series study was conducted using the National Coronial Information System (NCIS) to investigate drug-related deaths at music festivals throughout Australia between 1 July 2000 (Queensland from 1 January 2001) and 31 December 2019, using a list of keywords comprising music festival names and terms.

RESULTS

There were 64 deaths, of which most involved males (73.4%) aged in their mid-20s (range 15-50 years). Drug toxicity was the most common primary cause of death (46.9%) followed by external injuries (37.5%). The drug most commonly detected or reported as being used was MDMA (65.6%), followed by alcohol (46.9%) and cannabis (17.2%), with most cases reporting the use of two or more drugs (including alcohol) and 36% reporting a history of drug misuse in the coroner's findings. Most deaths were unintentional, with less than a fifth of cases (17.2%) involving intentional self-harm. Clinical intervention was involved in 64.1% of cases and most festivals occurred in inner city locations (59.4%).

CONCLUSIONS

The findings suggest that drug-related deaths at music festivals in Australia typically involve young people using multiple illicit substances in combination with alcohol. Most are unintentional and could potentially be prevented through the implementation of a range of harm reduction strategies, including mobile medical care, drug checking services, and increased consumer education and awareness.

Australian radiographers' awareness of cardiac implantable electronic devices (CIEDs) in mammographic imaging

INTRODUCTION

Women presenting for mammography occasionally have pacemakers or other cardiac-implantable electronic devices (CIEDs) in situ. This research investigates Australian radiographers' awareness of CIEDs in the diagnostic and screening settings.

METHODS

A survey of radiographers with mammography experience in Australia was conducted using SurveyMonkey™. Respondents were asked if they could confidently identify images of devices and whether they had imaged them mammographically. A Chi-squared test of independence was used to compare the association between demographics and CIED awareness. A value of p < 0.05 was deemed statistically significant.

RESULTS

There were 220 valid responses. All CIED types had been imaged. Most respondents had imaged a pacemaker (94.5%) and implantable cardioverter-defibrillator (ICD) (85.6%), compared to the three different implantable loop recorders (ILRs) (ILR-1: 63.4%; ILR-2: 14.1%; and IRL-3: 26.9% and the emerging subcutaneous ICDs (S-ICDs) (11.9%). Most respondents felt confident identifying the pacemaker (95%) and the ICD (86.1%). Only 19.4% of respondents could confidently identify the emerging S-ICD.

CONCLUSION

A lack of awareness of new and emerging devices may impact approaches to imaging and present significant risk to patients. The lack of studies comprehensively describing devices and their mammographic appearance to support radiographers' knowledge and awareness highlights an urgent need to progress research in this area.

IMPLICATIONS FOR PRACTICE

As a part of continuing professional development, radiographers performing mammography must ensure they remain up to date with current and emerging technology, including CIEDs. This study has identified a lack of awareness of the different types of CIEDs currently being implanted and imaged, which may translate to unsafe imaging practices. There is an urgent need for further education to bridge this knowledge gap and ensure the safety of practice in imaging women with CIEDs.

[The importance of a gender focus in building resilient, equitable, and universal health systemsA importância da abordagem de gênero no desenvolvimento de sistemas de saúde resilientes, equitativos e universais]

The coronavirus disease 2019 (COVID-19) pandemic demonstrated the need to strengthen the focus on gender from an integrative and multisectoral perspective to address health care problems. This article seeks to highlight the importance of incorporating and strengthening the gender focus in policies for building resilient, equitable, and universal health care systems. With this objective in mind, the role of women in the health sector is addressed from two directions. The first examines women's conditions of access to health systems in the Region of the Americas and highlights the need to overcome the obstacles that prevent the full realization of their right to health care. The second discusses the preponderant role of women in the health labor market, and the need to expand their leadership in decision-making in the sector. Finally, an appeal is made for progress in the implementation of recommendations to strengthen the focus on gender and the role of women in health policies and systems.

Using mixed methods to understand and tackle barriers to accessing health services

This report describes the experience and lessons learnt from designing and implementing a combined quantitative and qualitative method to assess barriers to accessing health services. This approach was developed to study barriers to access in five dimensions: availability; geographical, financial, and organizational accessibility; acceptability; contact; and effective coverage. The study design was used in six countries in the World Health Organization Region of the Americas. The findings highlight the importance of having a well defined analysis framework and the benefits of adopting a mixed-methods approach. Using existing data and contextualizing findings according to specific population groups and geographical areas were essential for relevance and utilization of the study outcomes. The findings demonstrate the feasibility of using mixed methods to understand the complexity of access problems faced by different subpopulations. By involving decision-makers from the beginning and allowing flexibility for sustained discussions, the analysis and findings had an impact. The engagement of health authorities and key stakeholders facilitated the use of the findings for collaborative identification of policy options to eliminate access barriers. Lessons learnt from the study emphasized the need for active participation of decision-makers, flexibility in the process, and sustained opportunities for discussion to ensure impact. Giving consideration to local priorities and adapting the methods accordingly were important for the relevance and use of the findings. Future efforts could consider incorporating mixed methods into national and local monitoring and evaluation systems.

[Recommendations for the development of resilient health systems in the AmericasRecomendações para o desenvolvimento de sistemas de saúde resilientes nas Américas]

This article offers opinion and analysis outlining strategic lines of action to build resilient health systems while promoting recovery in the post-COVID-19 pandemic period, with a view to maintaining and protecting public health gains. It contextualizes the challenges and opportunities in the Region of the Americas and offers recommendations for implementation of the strategic lines.It is urgent to promote the development of resilient health systems through the implementation of four lines of action defined in the strategy adopted by the Member States of the Pan American Health Organization in September 2021. The transformation of health systems must be based on the adoption of an integrated model of primary health care, a priority focus on the essential public health functions, strengthening of integrated health service networks, and increased public funding, especially for the first level of care. Implementation of these lines of action is focused not only on consolidating immediate crisis response; it is also framed within efforts toward the recovery and sustainable development of health systems, reducing their structural vulnerabilities to better prepare the response to future crises.

Mindfulness-Based Group Therapy for Chronic Pain Management in Older Adults

OBJECTIVES

There were two quality improvement goals for this project: (1) to evaluate the outcomes of an 8-week geriatric-focused mindfulness-based group therapy program for chronic pain management called "Mindfulness-based Chronic Pain Care" offered at a senior community center affiliated with a geriatric primary care clinic, and (2) to obtain feedback from participants to make relevant modifications for future groups.

METHODS

The program consisted of eight 150-minute weekly sessions. Thirteen community-dwelling older adults aged 60 and older participated in the program. The study utilized a non-randomized control-group pretest-posttest design. Participants completed pre- and post-program evaluations measuring pain and related psychosocial outcomes and were also asked to evaluate the importance of the group. Intervention and control groups were compared by t-test, chi-square likelihood ratio, Fischer's exact test, and multivariate analysis of variance with repeated measures.

RESULTS

There were statistically significant improvements in three areas: 1) increased activity level, 2) increased "pain willingness," and 3) decreased generalized anxiety symptoms. Qualitative analysis highlighted how this intervention was important to participants.

CONCLUSIONS

The results of this pilot program indicate promising outcomes for older adults suffering from chronic pain.

CLINICAL IMPLICATIONS

The Mindfulness-based Chronic Pain Care program was a practical, feasible, and acceptable approach for pain management among program participants.

Identifying access barriers faced by rural and dispersed communities to better address their needs: implications and lessons learned for rural proofing for health in the Americas and beyond

INTRODUCTION

Universal access to health services and universal health coverage are needed to achieve good health for all, yet rural communities face a variety of access barriers. As part of an effort to 'rural proof' health systems, it is therefore imperative to identify and act on the factors limiting access to health services by rural and indigenous communities. This article provides a comprehensive overview of the wide range of access barriers faced by rural and remote communities in two countries where barrier assessments were conducted. It also discusses the potential for barrier assessments to contribute evidence for rural proofing of national health policies, strategies, plans and programs.

METHODS

The study applied a concurrent triangulation design to collect and analyze data obtained from narrative-style literature reviews, in-depth interviews with local health authorities, and secondary analyses of existing household data on Guyana and Peru. These two countries were selected because they have some of the largest rural and indigenous populations in Latin America and the Caribbean, and have national policies in place for providing free, essential health services for these communities. Both quantitative and qualitative data were collected separately, and results were interpreted together. The main objective was to corroborate and cross-validate findings looking for convergence between the separate data analyses.

RESULTS

Seven dominant themes were identified across the two countries: use of traditional medicine and practice; decision making, gender, and family power dynamics; ethnicity and trust; knowledge and health literacy; geographic accessibility, health personnel and intercultural skills; and financial accessibility. The findings suggest that the interaction between these barriers may be as important as the singular role played by each factor, thereby highlighting the complex and multifactorial nature of accessing services in rural settings. Issues with limited availability of human resources for health were compounded by inadequate supplies and infrastructure. Financial barriers were often linked to the indirect costs of transport and geographic location, and further exacerbated by reduced socioeconomic status of rural communities, a majority of which are indigenous and have a strong preference for traditional medicines. Importantly, rural and indigenous communities experience considerable non-financial barriers related to issues of acceptability, which requires adaptation of health personnel and health service delivery models to the context-specific needs and realities of each rural community.

CONCLUSION

This study presented an approach for data collection and analysis that is both feasible and effective for evaluating access barriers in rural and remote communities. While this study explored access barriers through general health services in two rural settings, the issues identified reflect the structural deficiencies of many health systems. These challenges and singularities require adaptive organizational models for the provision of health services that respond to the specific characteristics of rural and indigenous communities. This study indicates the potential relevance of conducting assessments of barriers to health services as part of a wider approach to rural proofing and supports the notion that a mixed-methods approach, linking secondary analysis of existing relevant national survey data with focused key-informant interview data, may be an effective and efficient way to transform data into the knowledge policymakers need to rural proof health policies.

Barriers of Access to Opioid Medicines within the Context of Palliative Care in Latin America: The Perception of Health Professionals

Background: Different sets of barriers have been identified to explain the difficulties in the access and availability of opioid analgesics in palliative care, particularly in low- and middle-income countries, including Latin America. Objective: To validate a structured questionnaire for the access to opioid medicines and to investigate the perception of health professionals regarding access barriers to opioid analgesics in 17 countries of the Latin American Region. Design: Survey to identify the domains and barriers of access to opioid medicines according to health professionals, including physicians, nurses, and pharmacists affiliated to institutions that provide palliative care in Latin America between August 2019 and October 2020. Results: We analyzed responses from 426 health professionals. The median age was 44 years old (ranging from 23 to 73 years) with an average experience in palliative care of 10 years (range: 1-35), 71.8% were women, and 49.8% were affiliated to specialized health care facilities of urban areas (94.6%). The main barriers perceived to be extremely relevant by the respondents were "belief that patients can develop addiction" and "financial limitations of patients" for the patient's domain and the "appropriate education, instruction, and training of professionals" for health professional's domain. Conclusions: It is necessary to develop strategies to strengthen less-developed health systems of the region to review legal frameworks, ensure integrated palliative care systems, and deploy multidisciplinary strategies for sensitizing, training, and raising the awareness of patients, caregivers and, particularly, health professionals regarding appropriate prescription and rational use of opioid analgesics.

Towards applying the essential public health functions for building health systems resilience: A renewed list and key enablers for operationalization

The COVID-19 pandemic, climate change-related events, protracted conflicts, economic stressors and other health challenges, call for strong public health orientation and leadership in health system strengthening and policies. Applying the essential public health functions (EPHFs) represents a holistic operational approach to public health, which is considered to be an integrated, sustainable, and cost-effective means for supporting universal health coverage, health security and improved population health and wellbeing. As a core component of the Primary Health Care (PHC) Operational Framework, EPHFs also support the continuum of health services from health promotion and protection, disease prevention to treatment, rehabilitation, and palliative services. Comprehensive delivery of EPHFs through PHC-oriented health systems with multisectoral participation is therefore vital to meet population health needs, tackle public health threats and build resilience. In this perspective, we present a renewed EPHF list consisting of twelve functions as a reference to foster country-level operationalisation, based on available authoritative lists and global practices. EPHFs are presented as a conceptual bridge between prevailing siloed efforts in health systems and allied sectors. We also highlight key enablers to support effective implementation of EPHFs, including high-level political commitment, clear national structures for institutional stewardship on EPHFs, multisectoral accountability and systematic assessment. As countries seek to transform health systems in the context of recovery from COVID-19 and other public health emergencies, the renewed EPHF list and enablers can inform public health reform, PHC strengthening, and more integrated recovery efforts to build resilient health systems capable of managing complex health challenges for all people.

Association between antidementia medication use and mortality in people diagnosed with dementia with Lewy bodies in the UK: A retrospective cohort study

BACKGROUND

Dementia with Lewy bodies (DLBs) is a common cause of dementia but has higher mortality than Alzheimer's disease (AD). The reasons for this are unclear, but antidementia drugs (including acetylcholinesterase inhibitors [AChEIs] and memantine) symptomatically benefit people with DLB and might improve outcomes. We investigated whether AChEIs and/or memantine were associated with reduced hospital admissions and mortality.

METHODS AND FINDINGS

We performed a retrospective cohort study of those diagnosed with DLB between 1 January 2005 and 31 December 2019, using data from electronic clinical records of secondary care mental health services in Cambridgeshire and Peterborough NHS Foundation Trust (CPFT), United Kingdom (catchment area population approximately 0.86 million), as well as linked records from national Hospital Episode Statistics (HES) data. Eligible patients were those who started AChEIs or memantine within 3 months of their diagnosis (cases) and those who never used AChEIs or memantine (controls). Outcomes included admission, length of stay, and mortality. Cox proportional hazard and linear regression models were used. Of 592 patients with DLB, 219 never took AChEIs or memantine, 100 took AChEIs only, and 273 took both AChEIs and memantine. The cohorts were followed up for an average of 896 days, 981 days, and 1,004 days, respectively. There were no significant differences in the cohorts' baseline characteristics, except for socioeconomic status that was lower in patients who never took AChEIs or memantine (χ2 = 23.34, P = 0.003). After controlling for confounding by sociodemographic factors (age, sex, marital status, ethnicity, socioeconomic status), antipsychotic use, antidepressant use, cognitive status, physical comorbidity, anticholinergic burden, and global health performance, compared with patients who never took AChEIs or memantine, patients taking AChEIs only or taking both had a significantly lower risk of death (adjusted hazard ratio (HR) = 0.67, 95% CI = 0.48 to 0.93, p = 0.02; adjusted HR = 0.64, 95% CI = 0.50 to 0.83, P = 0.001, respectively). Those taking AChEIs or both AChEIs and memantine had significantly shorter periods of unplanned hospital admission for physical disorders (adjusted coefficient -13.48, 95% CI = [-26.87, -0.09], P = 0.049; adjusted coefficient -14.21, 95% CI = [-24.58, -3.85], P = 0.007, respectively), but no difference in length of stay for planned admissions for physical disorders, or for admissions for mental health disorders. No significant additional associations of memantine on admission, length of stay, and mortality were found (all P > 0.05). The main limitation was that this was a naturalistic study and possible confounds cannot be fully controlled, and there may be selection bias resulting from nonrandom prescription behaviour in clinical practice. However, we mimicked the intention-to-treat design of clinical trials, and the majority of baseline characters were balanced between cohorts. In addition, our series of sensitivity analyses confirmed the consistency of our results.

CONCLUSION

In this study, we observed that use of AChEIs with or without memantine in DLB was associated with shorter duration of hospital admissions and decreased risk of mortality. Although our study was naturalistic, it supports further the use of AChEIs in DLB.

El Campus Virtual de Salud Pública de la Organización Panamericana de la Salud como estrategia de cooperación técnica

El Campus Virtual de Salud Pública es la plataforma educativa de la Organización Panamericana de la Salud, concebida como herramienta para la cooperación técnica.

Los objetivos de este artículo son caracterizar la oferta de formación del Campus Virtual de Salud Pública identificando las propuestas de cursos virtuales; caracterizar a los participantes de los cursos; describir los procesos de actualización tecnológica y sus avances en términos de accesibilidad; e identificar su relación con las principales líneas de cooperación de la Organización Panamericana de la Salud.

El Campus Virtual de Salud Pública ha desarrollado 210 cursos con tutoría y 226 de autoaprendizaje desde 2007, relacionados con las políticas de la Organización. Se verificó un uso heterogéneo del campus en las distintas temáticas de la cooperación. La cantidad de cursos autoadministrados realizados durante la pandemia superó la cifra total acumulada en años previos.

Los participantes provienen principalmente de Latinoamérica. Un 67,5% son mujeres, con edades entre 26 y 45 años. Un 57,1% posee educación universitaria, principalmente en enfermería o medicina. La mitad trabaja en hospitales y un 35,8% en el primer nivel.

Más de un 90% de los participantes evaluaron favorablemente los temas abordados, recursos de conocimiento y características del aula virtual. Como dificultades, señalan escasa disponibilidad de tiempo y bajo acceso a internet. Como ventajas, destacan autonomía de horarios y acceso a diversas fuentes de información. Las herramientas de evaluación disponibles no son suficientes para reconocer el impacto de los programas educativos.

Se plantean los desafíos de profundizar en la accesibilidad y calidad de las propuestas educativas, fortalecer la relación con los temas de cooperación y mejorar la evaluación de los cursos y el conocimiento sobre los usuarios.

Aportes del nuevo marco para las funciones esenciales de salud pública a la lucha contra la pandemia de COVID-19

En el presente artículo se utiliza una perspectiva de rectoría de la salud, con el fin de interpretar las fortalezas y los obstáculos relativos a las capacidades de las autoridades nacionales de salud para responder ante la pandemia de COVID-19, a través del marco renovado de las funciones esenciales de salud pública (FESP). Sobre la base de una revisión bibliográfica, se sostiene que las capacidades institucionales que necesitan los países de la Región de las Américas para responder ante la pandemia de COVID-19 incluyen las cuatro etapas del nuevo ciclo de políticas en las FESP: la evaluación, la formulación de políticas, la asignación de recursos y el acceso. Aunque las autoridades de salud proporcionaron las funciones esenciales (por ejemplo, análisis de datos, diálogos intersectoriales en materia de políticas y asignación de fondos adicionales), las intervenciones que se implementaron estuvieron sujetas a las estructuras institucionales de cada país. Las autoridades de salud tuvieron que hacer frente a desafíos considerables como la fragmentación y la falta de capacidades institucionales y de personal, lo que pone en peligro la ejecución de actividades de respuesta eficaces y equitativas. Además, la respuesta a la pandemia ha sido desigual debido a algunas debilidades en la capacidad central de liderazgo y coordinación, la politización de las actividades de respuesta y las diferencias en la capacidad de respuesta a nivel subnacional. Esos desafíos son el reflejo de deficiencias estructurales que ya existían antes de que comenzara la pandemia, así como de la asignación de una prioridad baja a la salud pública en la agenda para el fortalecimiento de los sistemas de salud. En las agendas que se elaboren en el futuro debe darse prioridad a mejorar los elementos estructurales, fortalecer las capacidades de rectoría de las autoridades de salud y crear estructuras institucionales que garanticen tanto el acceso universal a la atención de salud como la cobertura universal de salud.

Contributions of the New Framework for Essential Public Health Functions to Addressing the COVID-19 Pandemic

This article uses a health stewardship perspective to interpret the strengths of and challenges to national health authorities' capacities to respond to the COVID-19 pandemic through the renewed essential public health functions (EPHF) framework. Based on a literature review, this article argues that the institutional capacities required by countries to respond to the COVID-19 pandemic in the Americas included all 4 stages of the new EPHF policy cycle: assessment, policy development, allocation of resources, and access. While health authorities provided these key functions (e.g., data analysis, intersectoral policy dialogues, allocation of additional funds), the interventions implemented depended on each country's own institutional structures. Health authorities faced significant challenges including fragmentation and the lack of institutional and personnel capacities, thus compromising the delivery of an effective and equitable response. In addition, the response to the pandemic has been uneven because of weaknesses in central leadership and coordination capacity, the politicization of the response, and differences in the capacity to respond at subnational levels. Such challenges reflect structural weaknesses that existed before the onset of the pandemic, as well as the low prioritization of public health in agendas for health systems strengthening. A future agenda should prioritize improving structural elements while strengthening the stewardship capacities of health authorities and developing institutional structures that guarantee access to and universal coverage of health services. (Am J Public Health. 2022;112(S6):S615-S620. https://doi.org/10.2105/AJPH.2022.306750).

Minimizing COVID-19 disruption: Ensuring the supply of essential health products for health emergencies and routine health services

Leveraging economies of scale and scope through multi-country pooled procurement enables countries to increase access to quality affordable essential medicines and supplies that meet priority health objectives as well as effectively respond to health emergencies. Strategic partnerships and tools can minimize supply chain disruptions and streamline procurement and deployment in health emergencies, thus mitigating stockouts and ensuring cost efficiencies across various therapeutic areas, including for public health programs at a time when countries may struggle to meet complex needs. As a means to better respond to health emergencies while maintaining priority public health programs, countries should optimize usage of pooled procurement mechanisms facilitated by multilateral technical cooperation and other regional mechanisms, such as the Pan American Health Organization's Strategic Fund. Because few analyses have assessed the role of such regional procurement mechanisms, this Health Policy paper evaluates the key areas of impact of the PAHO Strategic Fund and concludes with lessons learned to help prepare for future health crises while maintaining essential health services.

[Sustainable Development Goals: impact of lack of financial protection in health in Latin American and Caribbean countriesObjetivos de Desenvolvimento Sustentável: impacto da falta de proteção financeira em saúde nos países da América Latina e do Caribe]

Objetivo.

Determinar el impacto del gasto de bolsillo en salud en los hogares, los niveles de protección financiera y su desigualdad según variables relevantes en países de la Región. Se indaga su evolución y relación con el uso de servicios del sistema de salud.

Métodos.

Se recopila información descriptiva comparada acerca del gasto de bolsillo, su incidencia en la población, y su peso y composición en el consumo de los hogares. Se presentan indicadores de protección financiera en el nivel nacional y su distribución por quintiles de consumo total de hogares y por género. Se contrastan con un indicador de cobertura de servicios.

Resultados.

Los indicadores de gasto de bolsillo y protección financiera son deficientes pero diferenciados entre los países. Se identifica la composición del gasto en salud para un subgrupo de ellos y existen gradientes significativos cuando se estudian las desigualdades. Para algunos casos, se muestran cambios en el tiempo y posibles asociaciones con los niveles de cobertura de servicios.

Discusión.

La desprotección financiera afecta a una gran parte de la población, se configuran grupos de países con dificultades mayores que otros, con preponderancia de gasto en medicamentos y exposición mayor de grupos en situaciones de vulnerabilidad, como los más pobres y las mujeres, lo que denota una gran inequidad. Se identifican políticas de algunos países que pueden asociarse con la evolución de la protección financiera. Para reemplazar el gasto de bolsillo, barrera para el acceso, los países necesitan aumentar el gasto público mediante el financiamiento de los sistemas de salud en transformación hacia la salud universal.

POS1097 TREATMENT KNOWLEDGE AND PREFERENCES FOR BLACK PEOPLE WITH HIP AND KNEE OSTEOARTHRITIS: A SYSTEMATIC LITERATURE REVIEW AND META-ANALYSIS

Background:

Black people are less likely to undergo total joint arthroplasties, despite reporting more severe symptoms. (1) While racial disparities exist in treatment utilization for osteoarthritis, comprehensive studies of the treatment preferences of Black people have not been conducted.

Objectives:

The purpose of this manuscript is to systematically review the literature and identify Black osteoarthritis patients’ treatment preferences to understand how they may contribute to racial differences in the utilization of different treatment options.

Methods:

Searches ran on April 8, 2019 and April 7, 2020 in the following databases: Ovid MEDLINE (ALL - 1946 to Present); Ovid EMBASE (1974 to present); and The Cochrane Library (Wiley). Using the Patient/Population-Intervention-Comparison/Comparator-Outcome (PICO) format, our population of interest was Black people with hip and/or knee osteoarthritis, our intervention was preferences and opinions about treatment options for osteoarthritis, our comparator was white people with hip and/or knee osteoarthritis, and our outcome was preferences of osteoarthritis therapies. The protocol was registered under the PROSPERO international register, and the Preferred Reporting Items of Systematic reviews and Meta-Analyses (PRISMA) guidelines were followed.

Results:

Searches across the chosen databases retrieved 10,894 studies after de-duplication, 182 full text, and 31 selected for inclusion in this review. Black people were less likely to use NSAIDs or narcotic analgesics compared to white people. (Figure 1) Black people were more likely than white people to use spirituality and prayer, as well as topical treatments. Utilization of meditation, supplement/vitamin use, and hot/cold treatments was not significantly different between groups. Black people were less willing than white people to consider or undergo joint replacements, even if the procedure was needed and recommended by a physician.

Conclusion:

Racial differences persist in OA care across the spectrum of options. Future interventions should focus on providing accessible information surrounding treatment options and targeting perceptions of the importance of joint health.

POS1124 IDENTIFYING POTENTIAL CLASSIFICATION CRITERIA FOR CALCIUM PYROPHOSPHATE DEPOSITION DISEASE (CPPD): RESULTS FROM THE INITIAL PHASES

Background:

Classification criteria for calcium pyrophosphate deposition disease (CPPD) will facilitate clinical research on this common crystalline arthritis. ACR/EULAR are jointly sponsoring development of CPPD classification criteria using a multi-phase process.

Objectives:

To report preliminary results from the first two phases of a four-phase process for developing CPPD classification criteria.

Methods:

CPPD classification criteria development is overseen by a 12-member Steering Committee. Item generation (Phase I) included a scoping literature review of five literature databases and contributions from a 35-member Combined Expert Committee and two Patient Research Partners. Item reduction and refinement (Phase II) involved a Combined Expert Committee meeting, discussions among Clinical, Imaging, and Laboratory Advisory Groups, and an item rating exercise to assess the influence of individual items toward classification. The Steering Committee reviewed the modal rating score for each item (range -3 [strongly pushes away from CPPD] to +3 [strongly pushes toward CPPD]) to determine items to retain for future phases of criteria development.

Results:

Item generation yielded 420 items (312 from the literature, 108 from experts/patients). The Advisory Groups eliminated items they agreed were unlikely to distinguish between CPPD and other forms of arthritis, yielding 127 items for the item rating exercise. Fifty-six items, most of which had a modal rating of +/- 2 or 3, were retained for future phases (see Table 1). As numerous imaging items were rated +3, the Steering Committee recommended focusing on imaging of the knee, wrist, and one additional affected joint for calcification suggestive of CPP crystal deposition.

Conclusion:

The ACR/EULAR CPPD classification criteria working group has adopted both data- and expert-driven approaches, leading to 56 candidate items broadly categorized as clinical, imaging, and laboratory features. Remaining steps for criteria development include domain establishment, item weighting through a multi-criteria decision analysis exercise, threshold score determination, and criteria validation.

DEFINE-AF

Background

Identifying and targeting atrial substrate zones that are vulnerable to unidirectional block and slow conduction may be critical to improve the outcomes of atrial fibrillation (AF) ablation. Functional mapping of the atrial substrate with Decrement Evoked Potential (DeEP) and a single extrastimulus in this population could potentially lead to novel therapeutic strategies.

Aim

1) To systematically analyze whether the DEEP are present in the atrial tissue and their locations after pulmonary vein isolation. 2) To assess their relationship with the underlying voltage.  3) To assess the presence of DEEP as a function of the subtype of AF.

Methods

Consecutive patients with AF undergoing ablation were prospectively enrolled at 3 institutions. A biatrial voltage map was created and after pulmonary vein isolation (PVI). A drive train and an extrastimulus (atrial refractory period + 20ms) was delivered from an epicardial site (proximal CS) and an endocardial site (left atrial appendage (LAA). A multipolar mapping catheter was sequentially placed at 8 left atrial sites and 5 right atrial sites. Electrograms (EGMs) that showed a local delay of &gt;10ms in activation with the extrastimulus were identified as DEEPs. Patients were followed for a mean of 11 ± 5 months

Results

74 patients, 63 pers AF (85%), mean age 62 ± 8, mean LA size 41 ±12 mm were enrolled. Of 19240 EGMs analyzed, 8.2% showed DEEPs (54.6% with CS pacing and 45.4% with LAA pacing, p = 0.0001). The mean local decrement seen was 39 ms. Most DEEPs (76.2%) were identified in sites with a normal EGM at baseline with preserved voltages. DEEPs were differentially distributed within the regions mapped, more frequently in LA than RA (9.2% vs 6.6%, p &lt; 0.0001). Patients with persistent AF had a higher proportion of DEEPs than patients with paroxysmal AF (9.7% vs 5.1%, p &lt; 0.001).

Conclusions

Atrial DEEPs are: 1) More often identified when pacing endocardially. 2) More common in patients with persistent AF. 3) More frequent in the LA than in the RA. 4) Mostly located in regions with normal voltages at baseline. All those findings suggest the importance of the functional substrate mapping in the atrium and could lead to novel therapeutic targets. Abstract Figure. Example of atrial DEEP

How do delirium motor subtypes differ in phenomenology and contributory aetiology? a cross-sectional, multisite study of liaison psychiatry and palliative care patients

OBJECTIVES

To investigate whether delirium motor subtypes differ in terms of phenomenology and contributory aetiology.

DESIGN

Cross-sectional study.

SETTING

International study incorporating data from Ireland and India across palliative care, old age liaison psychiatry and general adult liaison psychiatry settings.

PARTICIPANTS

1757 patients diagnosed with delirium using criteria from the Diagnostic and Statistical Manual of Mental Disorders, Fourth edition (DSM IV).

PRIMARY AND SECONDARY OUTCOME MEASURES

Hyperactive, mixed and hypoactive delirium subtypes were identified using the abbreviated version of the Delirium Motor Subtype Scale. Phenomenology was assessed using the Delirium Rating Scale Revised. Contributory aetiologies were assessed using the Delirium Aetiology Checklist (DEC), with a score >2 indicating that the aetiology was likely or definitely contributory.

RESULTS

Hypoactive delirium was associated with dementia, cerebrovascular and systemic infection aetiologies (p<0.001) and had a lower overall burden of delirium symptoms than the other motor subtypes. Hyperactive delirium was associated with younger age, drug withdrawal and the DEC category other systemic aetiologies (p<0.001). Mixed delirium showed the greatest symptom burden and was more often associated with drug intoxication and metabolic disturbance (p<0.001). All three delirium motor subtypes had similar levels of impairment in attention and visuospatial functioning but differed significantly when compared with no subtype (p<0.001).

CONCLUSIONS

This study indicates a pattern of aetiology and symptomatology of delirium motor subtypes across a large international sample that had previously been lacking. It serves to improve our understanding of this complex condition and has implications in terms of early detection and management of delirium.

Contributions of synaptic and astrocyte physiology to the anaesthetised encephalogram revealed using a computational model

BACKGROUND

General anaesthesia is known to enhance inhibitory synaptic transmission to produce characteristic effects on the EEG and reduction in brain metabolism secondary to reduced neuronal activity. Evidence suggests that anaesthesia might have a direct effect on synaptic metabolic processes, and this relates to anaesthesia sensitivity. We explored elements of synaptic transmission looking for possible contributions to the anaesthetised EEG and how it may modulate anaesthesia sensitivity.

METHODS

We developed a Hodgkin-Huxley-type neural network computer simulation capable of mimicking anaesthetic prolongation of gamma-aminobutyric acid (GABA)ergic inhibitory postsynaptic potentials (IPSPs), and capable of altering postsynaptic ion homeostasis and neurotransmitter recycling. We examined their interactions on simulated electrocorticography (sECoG), and compared these with published anaesthesia EEG spectra.

RESULTS

The sECoG spectra from the model were comparable with published normal awake EEG spectra. Prolongation of IPSP duration in the model caused inhibition of high frequencies and saturation of low frequencies with a peak in keeping with current evidence. IPSP prolongation alone was unable to reproduce alpha rhythms or the generalised increase in EEG power found with anaesthesia. Adding inhibition of postsynaptic ion homeostasis to IPSP prolongation helped retain alpha rhythms, increased sECoG power, and antagonised the slow-wave saturation peak in a dose-dependent fashion that appeared dependent on the postsynaptic membrane potential, providing a plausible mechanism for how metabolic changes can modulate anaesthesia sensitivity.

CONCLUSIONS

Our model suggests how metabolic processes can modulate anaesthesia and produce non-receptor dependent drug sensitivity.

A renewed framework for the essential public health functions in the Americas

This report presents the results of a consensus decision making process conducted to elaborate a renewed conceptual framework of the essential public health functions for the Americas. The emerging framework consists of four pillars encompassing action-oriented components relating to the new scope and concerns of public health. The four pillars call for adopting a human rights approach to public health, addressing the social determinants of health, ensuring access to both individuals and population-based services, and expanding the stewardship role of health authorities through a collaborative implementation of public health functions. Public health functions were conceptualized as a set of capacities that are part of an integrated policy cycle the encompasses four stages: assessment, policy development, allocation of resources, and access. The framework provides a road map for evaluation and development by health authorities of integrated enabling public health policies through intersectoral collaboration. The application of the framework would require engaging countries working to improve public health through national assessments and systematic incorporation of these findings into quality improvement efforts and sectoral and intersectoral decision-making processes around policy and investments priorities promoted by governments. Work is ongoing in the definition of a list of public health functions that gives operational clarity to each dimension of this framework and guides performance evaluation.

Regulation of nursing practice in the Region of the Americas

OBJECTIVE

To describe and analyze the current nursing regulations across countries in the Region of the Americas.

METHODS

A country comparative analysis was carried out by gathering information from the ministries of health, nursing schools, councils, associations, and boards in 2018. The main categories evaluated were type of regulatory bodies, requirements for initial professional registration, and registration renewal.

RESULTS

All countries regulate the nursing profession through a regulatory body. Competency exams for initial registration are required in the United States, Canada, and most Caribbean countries. Registration renewal is required in 54.3% of the countries. Continuing education is required for professional registration renewal in the United States, Canada, and 53% of Caribbean countries. Labor hours are required in the United States and Canada.

CONCLUSION

Regulations promote and protect professional integrity. The Pan American Health Organization/World Health Organization recommends that countries make efforts to evaluate competency and training, consider the use of competency exams for initial registration, and add continuing education as requirements for registration renewal.

The Virgin Islands National Information Systems for Health: vision, actions, and lessons learned for advancing the national public health agenda

The British Virgin Islands (BVI) Ministry of Health and Social Development (MOHSD) recently identified the need for an updated strategy to advance the country's vision for Information Systems for Health (IS4H) ("Informed decision-making for better health outcomes"). Since the early 1990s, the MOHSD has recognized the importance of having strong conceptual foundations and mechanisms for its information systems, and the need to strengthen the production and use of good-quality health data to enable fulfillment of the territory's health goals. Therefore, in May 2017, BVI requested technical assistance from the Pan American Health Organization (PAHO) to develop a plan/"road map" for strengthening the MOHSD's stewardship capacity for IS4H. This resulted in a bilateral, country-led collaboration between PAHO and the Ministry to carry out two assessments of BVI's National Information Systems for Health (NISH): 1) a rapid assessment to map NISH policy, to develop a short- and medium-term workplan for strengthening and updating it, and 2) a maturity assessment, using PAHO's IS4H Maturity Model tool, to evaluate the implementation of NISH policy thus far and determine next steps. This article describes 1) the steps taken in this bilateral collaboration to update BVI's NISH policy and fine-tune its IS4H vision, including the development of a national plan/road map, and 2) lessons learned.

Effects of Deep Brain Stimulation on Eye Movements and Vestibular Function

Discovery of inter-latching circuits in the basal ganglia and invention of deep brain stimulation (DBS) for their modulation is a breakthrough in basic and clinical neuroscience. The DBS not only changes the quality of life of hundreds of thousands of people with intractable movement disorders, but it also offers a unique opportunity to understand how the basal ganglia interacts with other neural structures. An attractive yet less explored area is the study of DBS on eye movements and vestibular function. From the clinical perspective such studies provide valuable guidance in efficient programming of stimulation profile leading to optimal motor outcome. From the scientific standpoint such studies offer the ability to assess the outcomes of basal ganglia stimulation on eye movement behavior in cognitive as well as in motor domains. Understanding the influence of DBS on ocular motor function also leads to analogies to interpret its effects on complex appendicular and axial motor function. This review focuses on the influence of globus pallidus, subthalamic nucleus, and thalamus DBS on ocular motor and vestibular functions. The anatomy and physiology of basal ganglia, pertinent to the principles of DBS and ocular motility, is discussed. Interpretation of the effects of electrical stimulation of the basal ganglia in Parkinson's disease requires understanding of baseline ocular motor function in the diseased brain. Therefore we have also discussed the baseline ocular motor deficits in these patients and how the DBS changes such functions.

Five short screening tests in the detection of prevalent delirium: diagnostic accuracy and performance in different neurocognitive subgroups

BACKGROUND

Delirium is prevalent and serious, yet remains under-recognised. Systematic screening could improve detection; however, consensus is lacking as to the best approach. Our aim was to assess the diagnostic accuracy of five simple cognitive tests in delirium screening: six-item cognitive impairment test (6-CIT), clock-drawing test, spatial span forwards, months of the year backwards (MOTYB) and intersecting pentagons (IPT).

METHODS

A cross-sectional study was conducted. Within 36 h of admission, older medical patients were assessed for delirium using the Revised Delirium Rating Scale. They also underwent testing using the five cognitive tests outlined above. Sensitivity, specificity, positive and negative predictive values (PPV; NPV) were calculated for each method. Where appropriate, area under the receiver operating characteristic curve (AUC) was also calculated.

RESULTS

Four hundred seventy patients were included, and 184 had delirium. Of the tests scored on a scale, the 6-CIT had the highest AUC (0.876), the optimum cut-off for delirium screening being 8/9 (sensitivity 89.9%, specificity 62.7%, NPV 91.2%, PPV 59.2%). The MOTYB, scored in a binary fashion, also performed well (sensitivity 84.6%, specificity 58.4%, NPV 87.4%, PPV 52.8). On discriminant analysis, 6-CIT was the only test to discriminate between patients with delirium and those with dementia (without delirium), Wilks' Lambda = 0.748, p < 0.001.

CONCLUSION

The 6-CIT measures attention, temporal orientation and short-term memory and shows promise as a delirium screening test. This study suggests that it may also have potential in distinguishing the cognitive impairment of delirium from that of dementia in older patients. Copyright © 2016 John Wiley & Sons, Ltd.

Mindfulness-based forgiveness groups for older adults

Interventions that enable individuals to be more forgiving toward themselves and others are important for older adults. This article describes a group intervention for adults aged 60 or older that integrates forgiveness-related skills with a mindfulness approach. The Mindfulness-based Forgiveness Group was designed to meet for eight sessions. The skills taught included: recognizing one's own expectations and unenforceable rules, broadening one's perspectives about the context of the transgression, and discovering positive intentions through exercises as well as a variety of meditations to cultivate mindfulness, self-compassion and forgiveness. Data from five Mindfulness-Based Forgiveness Groups were collected. Based on pre- and post-test measures, analyses indicate that participants improved significantly in relation to forgiveness, mindfulness/self-compassion, and mental health. Using qualitative post-test data from participants, we identify elements of the intervention that appear to be helpful. Suggestions are provided for social workers seeking to replicate and build upon this promising intervention.

Oscillatory neural representations in the sensory thalamus predict neuropathic pain relief by deep brain stimulation

OBJECTIVE

Understanding the function of sensory thalamic neural activity is essential for developing and improving interventions for neuropathic pain. However, there is a lack of investigation of the relationship between sensory thalamic oscillations and pain relief in patients with neuropathic pain. This study aims to identify the oscillatory neural characteristics correlated with pain relief induced by deep brain stimulation (DBS), and develop a quantitative model to predict pain relief by integrating characteristic measures of the neural oscillations.

APPROACH

Measures of sensory thalamic local field potentials (LFPs) in thirteen patients with neuropathic pain were screened in three dimensional feature space according to the rhythm, balancing, and coupling neural behaviours, and correlated with pain relief. An integrated approach based on principal component analysis (PCA) and multiple regression analysis is proposed to integrate the multiple measures and provide a predictive model.

MAIN RESULTS

This study reveals distinct thalamic rhythms of theta, alpha, high beta and high gamma oscillations correlating with pain relief. The balancing and coupling measures between these neural oscillations were also significantly correlated with pain relief.

SIGNIFICANCE

The study enriches the series research on the function of thalamic neural oscillations in neuropathic pain and relief, and provides a quantitative approach for predicting pain relief by DBS using thalamic neural oscillations.
