Exploring implementation considerations for geriatric-HIV clinics: A secondary analysis from a scoping review on HIV models of geriatric care.

OBJECTIVES: This review aimed to map the current state of knowledge regarding the implementation considerations of existing geriatric-HIV models of care, to identify areas of further research and to inform the implementation of future geriatric-HIV interventions that support older adults living with HIV. METHODS: We conducted a scoping review that was methodologically informed by the Arskey and O'Malley's 5 step framework and theoretically informed by the Consolidated Framework for Implementation Research (CFIR). A systematic search of six databases was conducted for peer-reviewed literature. The grey literature was also searched. Article screening was performed in duplicate. Data was extracted for the purpose of this secondary analysis using a data extraction template informed by the CFIR. Data was inductively and deductively analyzed. RESULTS: In total, 11 articles met the inclusion criteria. The models of care described varied in terms of their location and setting, the number and type of care providers involved, the mechanism of patient referral, the type of assessments and interventions performed and the methods of longitudinal patient follow-up. Four key categories emerged to describe factors that influenced their implementation: care provider buy-in, patient engagement, mechanisms of communication and collaboration, and available resources. CONCLUSIONS: The findings from this scoping review provide an initial understanding of the key factors to consider when implementing geriatric-HIV models of care. We recommend health system planners consider mechanisms of communication and collaboration, opportunities for care provider buy-in, patient engagement and available resources. Future research should explore implementation in more diverse settings to understand the nuances that influence implementation and care delivery.

'Selection into training will always be an inexact process': A survey of Directors of Physician Education on selection into Basic Physician Training in Australia and New Zealand.

BACKGROUND: Despite being one of the largest medical specialty training programmes in Australasia, there is no standardised method for selection into Basic Physician Training (BPT), and limited data exist regarding current practices. AIMS: To address existing knowledge gaps, we aimed to create a 'snapshot' of current BPT selection practices and explore the perspectives of Directors of Physician Education (DPEs) regarding trainee selection. METHODS: An electronic survey of DPEs from adult and paediatric medicine BPT sites in Australia and New Zealand was undertaken in January-February 2022. A combination of free text, multiple-choice and yes/no answers were analysed using descriptive statistics and qualitative content analysis. RESULTS: A total of 70 responses were received, achieving a response rate of 35% (70/198). Selection practices were found to be heterogenous across BPT sites. Respondents had varying opinions regarding the utility of selection tools and desirable candidate attributes. A heavy reliance upon interviews and the reported use of subjective assessments raise concerns for selection process bias. CONCLUSION: BPT sites should critically evaluate their selection methods, and more research in this field is needed to establish best practice.

Understanding geriatric models of care for older adults living with HIV: a scoping review and qualitative analysis.

BACKGROUND: Advances in Human Immunodeficiency Virus (HIV) treatment have reduced mortality rates and consequently increased the number of individuals with HIV living into older age. Despite this, people aged 50 years and older have been left behind in recent HIV treatment and prevention campaigns, and a gold-standard model of care for this population has not yet been defined. Developing evidence-based geriatric HIV models of care can support an accessible, equitable, and sustainable HIV health care system that ensures older adults have access to care that meets their needs now and in the future. METHODS: Guided by Arksey & O'Malley (2005)'s methodological framework, a scoping review was conducted to determine the key components of, identify gaps in the literature about, and provide recommendations for future research into geriatric models of care for individuals with HIV. Five databases and the grey literature were systematically searched. The titles, abstracts and full texts of the search results were screened independently in duplicate. Data were analyzed using a qualitative case study and key component analysis approach to identify necessary model components. RESULTS: 5702 studies underwent title and abstract screening, with 154 entering full-text review. 13 peer-reviewed and 0 grey literature sources were included. Most articles were from North America. We identified three primary model of care components that may improve the successful delivery of geriatric care to people living with HIV: Collaboration and Integration; Organization of Geriatric Care; and Support for Holistic Care. Most articles included some aspects of all three components. CONCLUSION: To provide effective geriatric care to older persons living with HIV, health services and systems are encouraged to use an evidence-based framework and should consider incorporating the distinct model of care characteristics that we have identified in the literature. However, there is limited data about models in developing countries and long-term care settings, and limited knowledge of the role of family, friends and peers in supporting the geriatric care of individuals living with HIV. Future evaluative research is encouraged to determine the impact of optimal components of geriatric models of care on patient outcomes.

Identifying the areas of low self-reported confidence of internal medicine residents in geriatrics: a descriptive study of findings from a structured geriatrics skills assessment survey.

BACKGROUND: Currently, no standardized methods exist to assess the geriatric skills and training needs of internal medicine trainees to enable them to become confident in caring for older patients. This study aimed to describe the self-reported confidence and training requirements in core geriatric skills amongst internal medicine residents in Toronto, Ontario using a standardized assessment tool. METHODS: This study used a novel self-rating instrument, known as the Geriatric Skills Assessment Tool (GSAT), among incoming and current internal medicine residents at the University of Toronto, to describe self-reported confidence in performing, teaching and interest in further training with regard to 15 core geriatric skills previously identified by the American Board of Internal Medicine. RESULTS: 190 (75.1%) out of 253 eligible incoming (Year 0) and current internal medicine residents (Years 1-3) completed the GSAT. Year 1-3 internal medicine residents who had completed a geriatric rotation reported being significantly more confident in performing 13/15 (P < 0.001 to P = 0.04) and in teaching 9/15 GSAT skills (P < 0.001 to P = 0.04). Overall, the residents surveyed identified their highest confidence in administering the Mini-Mental Status Examination and lowest confidence in assessing fall risk using a gait and balance tool, and in evaluating and managing chronic pain. CONCLUSION: A structured needs assessment like the GSAT can be valuable in identifying the geriatric training needs of internal medicine trainees based on their reported levels of self-confidence. Residents in internal medicine could further benefit from completing a mandatory geriatric rotation early in their training, since this may improve their overall confidence in providing care for the mostly older patients they will work with during their residency and beyond.

Anomalous diffusion in thermoresponsive polymer-clay composite hydrogels probed by wide-field fluorescence microscopy.

Thermoresponsive materials exhibit an enormous potential for tissue engineering, separation systems, and drug delivery. We investigated the diffusion of laponite clay nanoparticles, which serve as physical cross-linkers to achieve improved material properties in poly(N-isopropylacrylamide) (PNIPAM)-clay composite hydrogels close to the gel point. The networks are formed through physical interactions between PNIPAM chains and clay nanoparticles after these two components are mixed. In contrast to previous studies, a covalent labeling strategy was chosen to minimize the amount of free dyes in solution. Single-particle tracking of the labeled clay nanoparticles showed that their diffusion is anomalous at all temperatures used in this study, reflecting the viscoelastic behavior as a cross-linker. Stepwise heating from 24 to 38 °C resulted in a slight increase of the diffusion coefficient and the anomality parameter α up to the volume phase transition temperature of ca. 31 °C, which was followed by a significant drop of both parameters, reflecting strongly hindered motion of the collapsed nanoparticle aggregates.

Exacerbated inequalities: A scoping review of the experiences of older persons during conflict situations.

BACKGROUND: We conducted the first known comprehensive literature review to (1) identify, categorize, and summarize the existing knowledge about the experiences of older persons and their caregivers during conflict situations; (2) identify the support needs of older persons and their caregivers, and; (3) identify gaps in the literature and understanding that may inform future research. METHODS: A scoping review methodology of academic peer-reviewed and gray English language literature was employed using six academic literature databases and one gray literature database. We further performed comprehensive searches of relevant search engines and organization websites and bibliographic hand searches to identify additional academic and gray literature. Two authors screened for eligibility of identified studies and documents. One reviewer extracted data regarding authors, article type, geographic origin, key participant characteristics, aims, study design and data collection method, results, conclusions and limitations. Data were analyzed thematically. RESULTS: 83 documents met this review's inclusion criteria, including 21 academic documents and 62 from the gray literature. Thematic analysis revealed that conflict situations exacerbate existing inequalities experienced by older persons. Within this overarching theme were three interconnected sub-themes: (1) Older adults are particularly vulnerable during conflict situations; (2) Older persons are inadequately supported in conflict situations; (3) In the face of great challenges, many older adults still manage to endure through conflict situations. We identified 15 recommendations from the reviewed documents to better support older adults in conflict situations. CONCLUSIONS: Existing inequalities, such as ageism and ableism, targeted discrimination, and poor health outcomes, become exacerbated during conflict situations, resulting in older persons being less able to flee and meet their daily needs with sufficient access to necessities and healthcare. Little is known of the experiences and needs of family caregivers during conflict situations. We identified several opportunities to improve the experience and support of older persons in conflict situations.

Productivity loss due to overweight and obesity: a systematic review of indirect costs.

OBJECTIVE: The increasingly high levels of overweight and obesity among the workforce are accompanied by a hidden cost burden due to losses in productivity. This study reviews the extent of indirect cost of overweight and obesity. METHODS: A systematic search was conducted in eight electronic databases (PubMed, Cochrane Library, Web of Science Core Collection, PsychInfo, Cinahl, EconLit and ClinicalTrial.gov). Additional studies were added from reference lists of original studies and reviews. Studies were eligible if they were published between January 2000 and June 2017 and included monetary estimates of indirect costs of overweight and obesity. The authors reviewed studies independently and assessed their quality. RESULTS: Of the 3626 search results, 50 studies met the inclusion criteria. A narrative synthesis of the reviewed studies revealed substantial costs due to lost productivity among workers with obesity. Especially absenteeism and presenteeism contribute to high indirect costs. However, the methodologies and results vary greatly, especially regarding the cost of overweight, which was even associated with lower indirect costs than normal weight in three studies. CONCLUSION: The evidence predominantly confirms substantial short-term and long-term indirect costs of overweight and obesity in the absence of effective customised prevention programmes and thus demonstrates the extent of the burden of obesity beyond the healthcare sector.
