An exploration of experts' perceptions on the use of interprofessional education to support collaborative practice in the care of community-living older adults.

Globally, as older adults are living longer and with more chronic conditions, there is a need to support their ability to age optimally in their homes and communities. Community-based interprofessional teams working closely with these older adults, their families, and informal caregivers will be instrumental in achieving this goal. Interprofessional education (IPE) is the means through which these teams can develop expertise in collaboratively working together with older adults. However, most IPE occurs in academic settings, and acute and long-term care sectors and little is known about IPE in the context of home and community care of older adults. The purpose of this study was to describe perceptions of academic and practice experts related to the current state of IPE in home and community care of older adults and the changes that are necessary to meet the future needs of practitioners and older adults. Using a qualitative descriptive design, interviews were conducted with 32 national and international key informants representing practitioners, educators, researchers, and health system decision-makers in the field of IPE. Thematic analysis of the data identified six themes: (a) client and family-centred care at the core of IPE, (b) the community as a unique learning setting across the learning continuum; (c) an aging-relevant IPE curriculum; (d) faculty commitment and resources for IPE; (e) technological innovation to support IPE; and (f) comprehensive IPE programme evaluation and research. These findings are explored through the lens of an interprofessional learning continuum model. The article concludes with a discussion of the study implications for IPE practice and research specifically in the care of community-living older adults.

Accreditation of a molecular HIV diagnostic laboratory following the Strengthening Laboratory Management Towards Accreditation (SLMTA)-Stepwise Laboratory Quality Improvement Process Towards Accreditation (SLIPTA) approach in Kenya: an implementation science study.

Introduction: accreditation is the most effective approach to ensure the quality of services. Laboratory performance can be evaluated using the World Health Organization (WHO)-SLIPTA checklist, which checks a laboratory´s compliance with ISO 15189 on a five-star score scale and improved using the SLMTA approach. Compliance is assessed by an external body and can result in accreditation. In this paper, we describe the steps taken by the Kenya Medical Research Institute (KEMRI) HIV Laboratory, Alupe, a resource-limited public entity, towards accreditation, and discuss the lessons learned. Methods: the laboratory adopted a SLMTA-SLIPTA approach that included targeted mentorship, on-site workshops, and training. Mentorship-based interventions were used to establish a robust quality management system. Targeted mentorship, on-site workshops, and training were conducted between September 2015 and July 2016. Audits used the SLIPTA checklist to detect gaps in 12 quality system essentials. Performance indicators including turnaround time, external quality assurance, sample rejection rates, and corrective actions were tracked. An external assessment by the national accreditation body was conducted between September 2016 and November 2016. Results: training and mentorship-based interventions were successfully conducted. Quality management systems aligned with ISO 15189 were established. Baseline, midterm, and exit audits yielded scores of 47%, 75%, and 94% respectively. Early infant diagnosis external quality assurance scores were 100% in 2014-2016, while average viral load scores were at 60%, 70% and 90% during the same period. Turnaround time from September 2015 surpassed the 80% target. Accreditation was awarded in March 2017. Conclusion: the SLMTA-SLIPTA approach is suitable for quality improvement in resource-limited laboratories.

Engagement of older adults with multimorbidity as patient research partners: Lessons from a patient-oriented research program.

BACKGROUND: Patient "engagement" in health research broadly refers to including people with lived experience in the research process. Although previous reviews have systematically summarized approaches to engaging older adults and their caregivers in health research, there is currently little guidance on how to meaningfully engage older adults with multimorbidity as research partners. OBJECTIVES: This paper describes the lessons learned from a patient-oriented research program, the Aging, Community and Health Research Unit (ACHRU), on how to engage older adults with multimorbidity as research partners. Over the past 7-years, over 40 older adults from across Canada have been involved in 17 ACHRU projects as patient research partners. METHODS: We developed this list of lessons learned through iterative consensus building with ACHRU researchers and patient partners. We then met to collectively identify and summarize the reported successes, challenges and lessons learned from the experience of engaging older adults with multimorbidity as research partners. RESULTS: ACHRU researchers reported engaging older adult partners across many phases of the research process. Five challenges and lessons learned were identified: 1) actively finding patient partners who reflect the diversity of older adults with multimorbidity, 2) developing strong working relationships with patient partners, 3) providing education and support for both patient partners and researchers, 4) using flexible approaches for engaging patients, and 5) securing adequate resources to enable meaningful engagement. CONCLUSION: The lessons learned through this work may provide guidance to researchers on how to facilitate meaningful engagement of this vulnerable and understudied subgroup in the patient engagement literature.

An evaluation study of caregiver perceptions of the Ontario's Health Links program.

INTRODUCTION: In 2012, the Ontario government launched Health Links (HL), which was designed to integrate care for patients with multimorbidity and complex needs who are high users of health services. This study evaluated perceptions of family and friend caregivers of patients enrolled in the HL program. Research questions included: What are (a) characteristics of caregivers of patients enrolled in HL (b) caregivers' perceptions of the program in relation to HL's guiding principles (patient and family-centred care, accessibility, coordination of services, and continuity of care and care provider) and (c) caregivers' perceptions of the impact of HL on themselves and their care recipient? METHODS: This study involved a survey and qualitative, semi-structured interviews. HL guiding principles (patient and family-centered care, accessibility, coordination of services, and continuity) guided the analysis. RESULTS: Twenty-seven surveys and 16 qualitative interviews were completed. Caregivers reported high levels of strain [Modified Caregiver Strain Index (MCSI) 15.5 (SD 7.03)], mild anxiety [Generalized Anxiety Disorder (GAD 7), 9.6 (SD 6.64)] and depression [Center for Epidemiological Studies Depression Scale (CES-D 10), 11.9 (SD 8.72)]. Regarding the guiding principles, most caregivers had a copy of the HL patient's care plan, although some caregivers noted that their needs were not included in the plan, nor were they asked for input. Caregivers found the program's home and phone visits accessible. Despite minimum wait times for community-based services, other access barriers persisted, (i.e., out-of-pocket costs). HL provided well-coordinated patient services, although some perceived that there was poor team communication. Caregiver perceptions varied on the quality of care provided. Provider continuity provided caregiver relief and patient support: A lack of continuity was related to changes in care coordinators and weekend staff and attrition. CONCLUSIONS: Caregivers of HL patients appreciated patient- and family-centred, accessible, consistent, coordinated and team-based approaches in care. Providers and decision-makers are urged to ensure that programs aimed at high system users address these core concepts while addressing caregivers' needs.

Capacity development among academic trainees in community-based primary health care research: The Aging, Community and Health Research Unit Experience.

Health care system capacity and sustainability to address the needs of an aging population are a challenge worldwide. An aging population has brought attention to the limitations associated with existing health systems, specifically the heavy emphasis on costly acute care and insufficient investments in comprehensive primary health care (PHC). Health system reform demands capacity building of academic trainees in PHC research to meet this challenge. The Aging, Community and Health Research Unit at McMaster University has purposefully employed a capacity building model for interdisciplinary trainee development. This paper will describe the processes and outcomes of the model, outlining how the provision of funding, mentorship, and a unique learning environment enables capacity building in networking, collaboration, leadership development, and knowledge mobilization among its trainees. The reciprocal advancement of the research unit through the knowledge and productivity of trainees will also be detailed.

Antibody repertoire development in the sheep.

The model of immunoglobulin (Ig) repertoire diversification in sheep has evolved dramatically in recent years. A process thought to involve the rearrangement of a very limited number of variable (V), diversity (D) and joining (J) segments followed by intense, antigen (Ag)-independent, somatic hypermutation is now known to be less recombinatorially restrictive and to involve fewer mutational events. Although mutation rates are now lower than previously thought, the somatic hypermutation process itself is no less critical to the development of the primary Ig repertoire in sheep. Recent studies have shown that those B cells that fail to mutate will die via apoptosis. Much of the V(D)J rearrangement is thought to occur in the fetal liver and spleen prior to development of the ileal Peyer's patch (PP) at approximately day 100 of gestation. Although de novo Ig rearrangement likely does not occur in the ileal PP, this tissue is a site of massive B-cell proliferation, selection and Ig diversification through somatic hypermutation.

The role of macrophages in the removal of apoptotic B-cells in the sheep ileal Peyer's patch.

In the process of generating the cells that populate the sheep's B-cell pool, the ileal Peyer's patch (PP) produces an immense number of B-cells and then destroys most of them by apoptosis. Rapid clearance of these apoptotic cells is essential for tissue homeostasis and for preventing pathology. Macrophages comprise a small percentage of cells in the follicles. They resemble macrophages found in other tissues and can be identified by the expression of MHC Class II and CD14. In this study, enriched macrophages co-cultured with apoptotic ileal PP cells showed increased DNA content as they ingested apoptotic cells. The higher the proportion of apoptotic cells in culture the greater the increase in DNA content of the macrophages. This occurred when B-cell apoptosis was initiated by a period in culture or in response to treating the animals with steroids. Thus, macrophages resident in the ileal PP follicle mediate the phagocytosis and removal of discarded B-cells.

The sheep and cattle Peyer's patch as a site of B-cell development.

In sheep and cattle, the ileal Peyer's patch (PP), which extends one-two meters along the terminal small intestine, is a primary lymphoid organ of B-cell development. B-cell diversity in the ileal PP is thought to develop by combinatorial mechanisms, gene conversion and/or point mutation. These species also have jejunal PP that function more like secondary lymphoid tissues concerned with mucosal immune reactions. These two types of PP differ significantly in their histology, ontogeny and the extent of lymphocyte traffic. The prenatal development of follicles in the PP begins first in the jejunum during the middle of gestation and then in the ileum during late gestation. B-cells proliferate rapidly in the ileal PP follicle; up to five percent of these cells survive while the majority dies by apoptosis, perhaps driven by the influence of environmental antigen and/or self-antigen. The surviving cells migrate from the ileal PP and populate the peripheral B-cell compartment. By adolescence, the ileal PP has involuted but the function of jejunal PP, compatible with a role as secondary lymphoid organ, continues throughout life. In this review, we focus on the development of PP as a site of B-cell repertoire generation, positive and negative B-cell selection, and the differences between ileal PP and jejunal PP.

A new model of sheep Ig diversification: shifting the emphasis toward combinatorial mechanisms and away from hypermutation.

The current model of Ig repertoire development in sheep focuses on the rearrangement of a small number (approximately 20) of Vlambda gene segments. It is believed that this limited combinatorial repertoire is then further diversified through postrearrangement somatic hypermutation. This process has been reported to introduce as many as 110 mutations/1000 nucleotides. In contrast, our data have that indicated somatic hypermutation may diversify the preimmune repertoire to a much lesser extent. We have identified 64 new Vlambda gene segments within the rearranged Ig repertoire. As a result, many of the unique nucleotide patterns thought to be the product of somatic hypermutation are actually hard-coded within the germline. We suggest that combinatorial rearrangement makes a much larger contribution, and somatic hypermutation makes a much smaller contribution to the generation of diversity within the sheep Ig repertoire than is currently acknowledged.
