Experience of Family Members of Relatives With Substance Use Disorders: An Integrative Literature Review.

Background: Substance use disorders (SUDs) present substantial challenges for family members living with or supporting relatives with SUDs. This review explores existing literature on family members' experiences with relatives with SUDs and their support needs. Method: An integrative review was conducted by searching literature in the Cumulative Index of Nursing and Allied Health, PubMed, PsycINFO, ProQuest, and Scopus databases. Results: Five themes were generated based on analysis of 26 empirical studies: (a) family members' and caregivers' experiences of SUDs; (b) impact of SUDs-related aggressive/violent behaviors on families; (c) dilemmas faced by family members; (d) culture and family stigma related to SUDs; and (e) factors contributing to SUDs, challenges, and support needs. The review highlighted barriers to seeking support due to stigma and guilt, underscoring the need for structured support programs. Conclusions: This review sheds light on the challenges faced by family members with relatives suffering from SUDs and emphasizes the crucial need for structured support programs. The findings provide insights for developing initiatives to address the social and trauma-induced needs of family members and to establish support resources for them.

Perspectives on the implementation of health informatics curricula frameworks.

BACKGROUND: The COVID-19 pandemic highlighted the necessity of equipping health professionals with knowledge and skills to effectively use digital technology for healthcare delivery. However, questions persist about the best approach to effectively educate future health professionals for this. A workshop at the 15th Nursing Informatics International Congress explored this issue. OBJECTIVE: To report findings from an international participatory workshop exploring pre-registration informatics implementation experiences. METHODS: A virtual workshop was held using whole and small group interactive methods aiming to 1) showcase international examples of incorporating health informatics into pre-registration education; 2) highlight essential elements and considerations for integrating health informatics into curricula; 3) identify integration models of health informatics; 4) identify core learning objectives, resources, and faculty capabilities for teaching informatics; and 5) propose curriculum evaluation strategies. The facilitators' recorded data and written notes were content analysed. RESULTS: Fourteen participants represented seven countries and a range of educational experiences. Four themes emerged: 1) Design: scaffolding digital health and technology capabilities; 2) Development: interprofessional experience of and engagement with digital health technology capabilities; 3) implementation strategies; and 4) Evaluation: multifaceted, multi-stakeholder evaluation of curricula. These themes were used to propose an implementation framework. DISCUSSION: Workshop findings emphasise global challenges in integrating health informatics into curricula. While course development approaches may appear linear, the learner-centred implementation framework based on workshop findings, advocates for a more cyclical approach. Iterative evaluation involving stakeholders, such as health services, will ensure that health professional education is progressive and innovative. CONCLUSIONS: The proposed implementation framework serves as a roadmap for successful health informatics implementation into health professional curricula. Prioritising engagement with health services and digital health industry is essential to ensure the relevance of implemented informatics curricula for the future workforce, acknowledging the variability in placement experiences and their influence on informatics exposure, experience, and learning.

Black family members' cultural beliefs and experiences regarding substance use and misuse by relatives: A focused ethnography.

Research explored substance use in Black communities in Canada, but a gap exists about the experiences of Black family members, caring for relatives with substance misuse within the Canadian context. Black family members are defined as African Canadians, Caribbean Canadian or Caribbean Blacks. This paper explores Black family members' beliefs and experiences regarding their relatives' psychoactive substance use and misuse. A focused ethnography was conducted with 26 Black family members with 17 participants originated from various parts of Africa, and nine participants originated from parts of the Caribbean. Participants comprised of mothers (n = 5), fathers (n = 2), step-fathers (n = 1), husbands (n = 1), wives (n = 2), uncles (n = 5), aunties (n = 2), siblings (n = 5), in-laws (n = 2), and guardians (n = 1). Three themes were generated: cultural beliefs and perceptions regarding substance use and misuse of family relatives; "When he starts drinking, hell breaks loose": Perceived impact of substance misuse on family safety and stability; and, the experiences of stigma and the keeping of secrets. Prioritizing public health approaches, such as public policies and campaigns that dismantle stigma and systemic barriers, and increase awareness about substance use and harm reduction interventions among Black communities.

Prevalence of dementia among people experiencing homelessness in Ontario, Canada: a population-based comparative analysis.

BACKGROUND: Cognitive decline in people experiencing homelessness is an increasingly recognised issue. We compared the prevalence of dementia among people experiencing homelessness to housed individuals in the general population and those living in low-income neighbourhoods. METHODS: We conducted a population-based, cross-sectional, comparative analysis using linked health-care administrative data from Ontario, Canada. We included individuals aged 45 years or older on Jan 1, 2019, who visited hospital-based ambulatory care (eg, emergency department), were hospitalised, or visited a community health centre in 2019; and identified people experiencing homelessness if they had one or more health-care records with an indication of homelessness or unstable housing. Prevalence of dementia was ascertained as of Dec 31, 2019, using a validated case definition for Alzheimer's disease and related dementia that was modified to include diagnoses made at a community health centre. Poisson models were used to generate estimates of prevalence. Estimates were compared with Ontarians that accessed any of the same health-care services over the same time, overall (general population group), and among those who were in the lowest quintile of area-based neighbourhood income (low-income group). FINDINGS: 12 863 people experiencing homelessness, 475 544 people in the low-income comparator group, and 2 273 068 people in the general population comparator group were included in the study. Dementia prevalence was 68·7 per 1000 population among people experiencing homelessness, 62·6 per 1000 population in the low-income group, and 51·0 per 1000 population in the general population group. Descriptively, prevalence ratios between people experiencing homelessness and the comparator groups were highest within the ages of 55-64 years and 65-74 years in both sexes, ranging from 2·98 to 5·00. After adjusting for age, sex, geographical location of residence (urban vs rural), and health conditions associated with dementia, the prevalence ratio of dementia among people experiencing homelessness was 1·71 (95% CI 1·60-1·82) compared with the low-income group and 1·90 (1·79-2·03) compared with the general population group. INTERPRETATION: People experiencing homelessness experience a high burden of dementia compared with housed populations in Ontario. Findings suggest that people experiencing homelessness might experience dementia at younger ages and could benefit from the development of proactive screening and housing interventions. FUNDING: The Public Health Agency of Canada.

Early Psychosis Intervention and Primary Care: A Mixed Methods Study of Family Physician Knowledge, Attitudes, Preferences, and Needs.

Family physicians (FPs) play an important but underappreciated role in the pathways to care for people with early psychosis. We conducted a mixed-methods study to describe the knowledge, attitudes, preferences, and needs of FPs towards the recognition and management of early psychosis. We sent a cross-sectional postal survey to a random sample of FPs in Ontario, Canada, and conducted in-depth qualitative interviews with twenty. FPs were generally aware of important early psychosis symptoms, however, there were some knowledge gaps. Among surveyed FPs, 25% were unsure of the availability of early psychosis intervention services in their region, and most (80%) would prefer to co-manage with specialists. In the qualitative interviews, FPs expressed varied comfort levels in recognizing psychosis, and that timely access to psychiatry was a main concern. Our findings suggest that FPs require better support in recognizing and managing early psychosis and facilitating connections with specialized care.

Toxic Relationships Described by People With Breast Cancer on Reddit: Topic Modeling Study.

BACKGROUND: Social support is essential to promoting optimal health outcomes for women with breast cancer. However, an estimated 12% of women with breast cancer simultaneously experience intimate partner violence (IPV; physical, psychological, or sexual abuse by an intimate partner). Women who experience IPV during breast cancer may lack traditional social support, and thus seek out alternative sources of support. Online community forums, such as Reddit, can provide accessible social connections within breast cancer-specific communities. However, it is largely unknown how women with breast cancer use Reddit to describe and seek support for experiences of IPV. OBJECTIVE: This study aims to explore how patients with breast cancer describe toxic relationships with their partners and immediate family members on Reddit. METHODS: This exploratory, cross-sectional, topic-modeling study analyzed textual data from 96 users in the r/breastcancer subreddit in February 2023. The meaning extraction method, inclusive of principal component analysis, was used to identify underlying components. Components were subjected to sentiment analysis and summative content analysis with emergent categorical development to articulate themes. RESULTS: Seven themes emerged related to toxic relationships: (1) contextualizing storytelling with lymph nodes, (2) toxic behavior and venting emotions, (3) abandonment and abuse following diagnosis, (4) toxic relationships and social-related fears, (5) inner strength and navigating breast cancer over time, (6) assessing social relationships and interactions, and (7) community advice and support. Toxic relationships were commonly characterized by isolation, abandonment, and emotional abuse, which had profound emotional consequences for patients. Reddit facilitated anonymous venting about toxic relationships that helped patients cope with intense feelings and stress. Exchanging advice and support about navigating toxic relationships during breast cancer were core functions of the r/breastcancer community. CONCLUSIONS: Findings emphasized the value of Reddit as a source of social support for patients with breast cancer experiencing toxic relationships. Clinicians who understand that many patients with breast cancer experience toxic relationships and considerable psychological sequelae are better prepared to support their patients' holistic well-being. Further investigation of Reddit as a possible resource for advice, information, and support has the potential to help inform clinical practice and subsequently, patient health outcomes.

Evaluating the Appropriateness of Podcasts to Improve the Knowledge and Awareness of Selected Health Topics Among Undergraduate General Nursing Students: Protocol for an International Feasibility Study.

BACKGROUND: Podcasts have proven to be a successful alternative source of educational material for students. Given the ability to listen to podcasts 24/7 and while on the go, this technology has the potential to provide informative and educational material to a large number of people at any given time. Podcasts are usually freely available on commonly used mobile devices, such as smartphones, laptops, and tablets. OBJECTIVE: This paper describes the impact of health-related podcasts as an intervention tool to support the knowledge and awareness of nursing students on a given topic. METHODS: Pre- and postpodcast questionnaires will gather data regarding the participants' knowledge and awareness of two topics-gestational diabetes and mental health. This intervention will be tested on general nursing undergraduate students. The total number of students (N=2395) from the participating universities are broken down as follows: (1) University College Cork (n=850) and the University of Galway (n=450) in Ireland, (2) Mzuzu University in Malawi (n=719), and (3) University of Fort Hare in South Africa (n=376). RESULTS: The study received ethical approval from the University College Cork Ethics Committee (2022-027A1). The approval obtained from University College Cork sufficed as ethics coverage for the University of Galway in Ireland. Ethics approval was also received from the Mzuzu University Research Ethics Committee (ID MZUNIREC/DOR/23/28) and the Inter-Faculty Research Ethics Committee of the University of Fort Hare (ID CIL002-21). Data collection is currently underway and will continue until the end of February 2024. The quantitative and qualitative data are expected to be analyzed in March 2024. CONCLUSIONS: Results from this study will allow for an investigation into the impact of podcasts in different settings: a high-income country (Ireland), an upper-middle-income country (South Africa), and a low-to-middle-income country (Malawi). The data gathered from this feasibility study will provide more clarity on the potential utility of podcasts as an intervention tool. We will gather data regarding listener demographics (eg, country of residence, age, gender, and year of study). INTERNATIONAL REGISTERED REPORT IDENTIFIER (IRRID): DERR1-10.2196/50735.

Opioid-related overdose deaths among people experiencing homelessness, 2017 to 2021: A population-based analysis using coroner and health administrative data from Ontario, Canada.

AIMS: To measure the change in proportion of opioid-related overdose deaths attributed to people experiencing homelessness and to compare the opioid-related fatalities between individuals experiencing homelessness and not experiencing homelessness at time of death. DESIGN, SETTING AND PARTICIPANTS: Population-based, time-trend analysis using coroner and health administrative databases from Ontario, Canada from 1 July 2017 and 30 June 2021. MEASUREMENTS: Quarterly proportion of opioid-related overdose deaths attributed to people experiencing homelessness. We also obtained socio-demographic and health characteristics of decedents, health-care encounters preceding death, substances directly contributing to death and circumstances surrounding deaths. FINDINGS: A total of 6644 individuals (median age = 40 years, interquartile range = 31-51; 74.1% male) experienced an accidental opioid-related overdose death, among whom 884 (13.3%) were identified as experiencing homelessness at the time of death. The quarterly proportion of opioid-related overdose deaths attributed to people experiencing homelessness increased from 7.2% (26/359) in July-September 2017 to 16.8% (97/578) by April-June 2021 (trend test P < 0.01). Compared with housed decedents, those experiencing homelessness were younger (61.3 versus 53.1% aged 25-44), had higher prevalence of mental health or substance use disorders (77.1 versus 67.1%) and more often visited hospitals (32.1 versus 24.5%) and emergency departments (82.6 versus 68.5%) in the year prior to death. Fentanyl and its analogues more often directly contributed to death among people experiencing homelessness (94.0 versus 81.4%), as did stimulants (67.4 versus 51.6%); in contrast, methadone was less often present (7.8 versus 12.4%). Individuals experiencing homelessness were more often in the presence of a bystander during the acute toxicity event that led to death (55.8 versus 49.7%); and where another individual was present, more often had a resuscitation attempted (61.7 versus 55.1%) or naloxone administered (41.2 versus 28.9%). CONCLUSIONS: People experiencing homelessness account for an increasing proportion of fatal opioid-related overdoses in Ontario, Canada, reaching nearly one in six such deaths in 2021.

Access to a regular primary care physician among young people with early psychosis in Ontario, Canada.

AIM: Access to a primary care physician in early psychosis facilitates help-seeking and engagement with psychiatric treatment. We examined access to a regular primary care physician in people with early psychosis, compared to the general population, and explored factors associated with access. METHODS: Using linked health administrative data from Ontario (Canada), we identified people aged 14-35 years with a first diagnosis of nonaffective psychotic disorder (n = 39 449; 2005-2015). We matched cases to four randomly selected general population controls based on age, sex, neighbourhood, and index date (n = 157 796). We used modified Poisson regression to estimate prevalence ratios (PR) for access to a regular primary care physician in the year prior to first diagnosis of psychotic disorder, and the sociodemographic and clinical factors associated with access. RESULTS: A larger proportion of people with early psychosis had a regular primary care physician, relative to the general population (89% vs. 68%; PR = 1.30, 95%CI = 1.30-1.31). However, this was accounted for by a higher prevalence of comorbidities among people with psychosis, and this association was no longer present after adjustment (PR = 0.97, 95%CI = 0.97, 0.98). People with early psychosis who were older, male, refugees and those residing in lower income or high residential instability neighbourhoods were less likely to have a regular primary care physician. CONCLUSION: Approximately one in ten young people with early psychosis in Ontario lack access to a regular primary care physician. Strategies to improve primary care physician access are needed for management of physical comorbidities and to ensure continuity of care.

Web-Based Presence for Social Connectedness in Long-Term Care: Protocol for a Qualitative Multimethods Study.

BACKGROUND: The COVID-19 pandemic and resultant restrictions on social gatherings significantly impacted many peoples' sense of social connectedness, defined as an individual's subjective sense of having close relationships with others. Older adults living in long-term care homes (LTCHs) experienced extreme restrictions on social gatherings, which negatively impacted their physical and mental health as well as the health and well-being of their family caregivers. Their experiences highlighted the need to reconceptualize social connectedness. In particular, the pandemic highlighted the need to explore novel ways to attain fulfilling relationships with others in the absence of physical gatherings such as through the use of a hybridized system of web-based and in-person presence. OBJECTIVE: Given the potential benefits and challenges of web-based presence technology within LTCHs, the proposed research objectives are to (1) explore experiences regarding the use of web-based presence technology (WPT) in support of social connectedness between older adults in LTCHs and their family members, and (2) identify the contextual factors that must be addressed for successful WPT implementation within LTCHs. METHODS: This study will take place in south western Ontario, Canada, and be guided by a qualitative multimethod research design conducted in three stages: (1) qualitive description with in-depth qualitative interviews guided by the Technology Acceptance Model (TAM) and analyzed using content analysis; (2) qualitative description and document analysis methodologies, informed by content and thematic analysis methods; and (3) explicit between-methods triangulation of study findings from stages 1 and 2, interpretation of findings and development of a guiding framework for technology implementation within LTCHs. Using a purposeful, maximum variation sampling approach, stage 1 will involve recruiting approximately 45 participants comprising a range of older adults, family members (30 participants) and staff (15 participants) within several LTCH settings. In stage 2, theoretical sampling will be used to recruit key LTCH stakeholders (directors, administrators, and IT support). In stage 3, the findings from stages 1 and 2 will be triangulated and interpreted to develop a working framework for WPT usage within LTCHs. RESULTS: Data collection will begin in fall 2023. The findings emerging from this study will provide insights and understanding about how the factors, barriers, and facilitators to embedding and spreading WPT in LTCHs may benefit or negatively impact older adults in LTCHs, family caregivers, and staff and administrators of LTCHs. CONCLUSIONS: The results of this research study will provide a greater understanding of potential approaches that could be used to successfully integrate WPTs in LTCHs. Additionally, benefits as well as challenges for older adults in LTCHs, family caregivers, and staff and administrators of LTCHs will be identified. These findings will help increase knowledge and understanding of how WPT may be used to support social connectedness between older adults in LTCHs and their family members.

Breastfeeding experiences of patients in baby-friendly certified hospital settings: protocol for a scoping review.

INTRODUCTION: The Baby-friendly Hospital Initiative is a global programme that is meant to support breastfeeding within organisations. Most of the current literature is focused on implementation and uptake of the programme; however, little is known about the patient experience of breastfeeding within these settings. By exploring this current gap in the literature, we may discover important contextual elements of the breastfeeding experience. The objective of this protocol is to provide a framework for a scoping review where we aim to understand the extent and type of evidence in relation to the patient experience of breastfeeding in Baby-friendly Hospital Initiative (BFHI)-certified settings. METHODS AND ANALYSIS: The proposed scoping review will be conducted in accordance with the Joanna Briggs Institute methodology for scoping reviews. The databases to be searched for relevant literature include MEDLINE, Embase, PsycINFO, CINAHL and Scopus in April 2023. A grey literature scan will include reviewing documents from professional organisations/associations. For all sources of evidence that meet the inclusion criteria, data will be extracted and presented in a table format. The results of the search and the study inclusion process will be reported in full in the final scoping review and presented in a Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for scoping reviews. Participants in this review will include any individual who delivered their baby in a BFHI-certified setting. Exploring the patient experience will involve reviewing their subjective perceptions of events related to breastfeeding. These events must occur in a BFHI-certified hospital, and therefore, home births and other outpatient settings will be excluded. ETHICS AND DISSEMINATION: Ethical approval is not required for this scoping review protocol or the final review. Knowledge gained from this research will be disseminated through the primary author's PhD dissertation work, as well as manuscript publications and conference presentations.

Effects of Individual and Pair Housing of Calves on Short-Term Health and Behaviour on a UK Commercial Dairy Farm.

Social pair housing of calves has previously demonstrated positive impacts for calves, so this study aimed to compare the health and behaviour of calves kept in individual compared to pair housing on a single commercial UK dairy farm. A total of 457 Holstein and Jersey heifer calves were recruited and systematically allocated to individual and pair housing. Weekly visits were conducted up to 8 weeks of age, with weight and presence of clinical disease measured using both a standardized scoring system and thoracic ultrasonography. A subset of calves (n = 90) had accelerometers attached to monitor activity, with CCTV placed above a further 16 pens to allow behavioural assessments to be made via continuous focal sampling at 1 and 5 weeks of age. During the study, there was a mortality rate of 2.8%, and an average daily liveweight gain (ADLG) of 0.72 kg/day, with no significant effect of housing group (p = 0.76). However, individually housed calves had increased odds of developing disease (OR = 1.88, p = 0.014). Accelerometer data showed that housing group had no effect on lying times, with a mean of 18 h 11 min per day (SD 39 min) spent lying down. The motion index was significantly higher in pair-housed calves (F1,83 = 440.3, p < 0.01), potentially due to more social play behaviour. The total time engaged in non-nutritive oral behaviours (NNOBs) was not impacted by housing group (p = 0.72). Pair-housed calves split their time conducting NNOBs equally between inanimate objects and on their pen mates' body. Individually housed calves spent significantly more time with their head out of the front of the pen (p = 0.006), and also engaged in more self-grooming than pair-housed calves (p = 0.017), possibly due to a lack of socialization. The overall findings of this study indicate that within a UK commercial dairy management system, pair-housed calves were healthier and more active than individually housed calves, while housing group did not influence ADLG or the occurrence of NNOBs.

SARS-CoV-2 Testing and Complications Across 6 Waves of the COVID-19 Pandemic Among Individuals Recently Experiencing Homelessness in Ontario, Canada.

This cohort study compares the rates of SARS-CoV-2 testing and complications across 6 waves of the COVID-19 pandemic in Ontario, Canada, between individuals recently experiencing homelessness, low-income residents, and the general population.

Designing and delivering digital learning (e-Learning) interventions in nursing and midwifery education: A systematic review of theories.

AIMS /OBJECTIVES: To identify and synthesise theories that support the design and delivery of digital learning interventions in nursing and midwifery education. BACKGROUND: A range of educational and other theories are used to support nursing and midwifery education, including when e-learning interventions are being designed and delivered. However, there is a limited understanding of how theory is applied across the wide range of digital learning interventions to inform pedagogical research and practice. DESIGN: A systematic review. METHODS: CINAHL, ERIC, MEDLINE and PubMed were searched using key terms. Studies were screened by independent reviewers checking the title, abstract and full text against eligibility criteria. Due to the theoretical focus of the review, critical appraisal was not undertaken. Data were extracted and synthesised using a descriptive approach. RESULTS: Thirty-four studies were included. Twenty theories were identified from a range of scientific disciplines, with the Technology Acceptance Model and Theory of Self-Efficacy employed most often. Theoretical frameworks were used to inform and explain how the digital learning interventions were designed or implemented in nursing and midwifery education. The sample were mainly undergraduate nursing students and the digital learning interventions encompassed animation, blended approaches, general technologies, mobile, online, virtual simulation and virtual reality applications which were used mainly in university settings. CONCLUSIONS: This systematic review found a range of theories that support the design and delivery on digital learning interventions in nursing and midwifery education. While a single theory, the Technology Acceptance Model, tended to dominate the literature, the evidence base is peppered with numerous theoretical models that need to be examined more rigorously to ascertain their utility in improving the design or implementation of digital forms of learning to improve pedagogical research and practice in nursing and midwifery.

Homeowner perspectives on the implementation of the Community Homes for Opportunity (CHO) program: an ethnographic group homes study in Southwestern Ontario Canada.

BACKGROUND: The global extant literature acknowledge that housing serves as a key social determinant of health. Housing interventions that involve group homes have been found to support the recovery of persons with mental illness and those with addiction issues. The current study explored the views of homeowners in relation to a supportive housing program called Community Homes for Opportunity (CHO) that modernised a provincial group home program (Homes for Special Care [HSC]) and provided recommendations for improving the program implementation in other geographical areas of Ontario. METHODS: We applied ethnographic qualitative techniques to purposefully recruit 36 homeowner participants from 28 group homes in Southwest Ontario, Ontario Canada. Focus group discussions were conducted at two time points, during CHO program implementation (Fall 2018, and post implementation phases (Winter 2019) respectively. RESULTS: Data analysis yielded 5 major themes. These include: (1) general impressions about the modernization process, (2) perceived social, economic and health outcomes, (3) enablers of the modernization program, (4) challenges to implementation of the modernization program, and (5) suggestions for implementation of the CHO in future. CONCLUSIONS: A more effective and expanded CHO program will need the effective collaboration of all stakeholders including homeowners for successful implementation.

An integrative review of adult patient-reported reasons for non-urgent use of the emergency department.

OBJECTIVE: To conduct an integrative review of the scientific literature to explore adult patient-reported reasons for using the emergency department (ED) non-urgently. METHOD: A literature search of CINAHL, Cochrane, Embase, PsycINFO, and MEDLINE was conducted with filters for humans, published January 1, 1990-September 1, 2021, and English language. Methodological quality was assessed using Critical Appraisal Skills Programme Qualitative Checklist for qualitative and National Institutes Health (NIH) Quality Assessment Tool for Observational Cohort and Cross-Sectional Studies for quantitative studies. Data was abstracted on study and sample characteristics, and themes/reasons for ED use. Cited reasons were coded using thematic analysis. RESULTS: Ninety-three studies met inclusion criteria. Seven themes were found: need to be risk averse with respect to the health issue; knowledge and awareness of alternative sources of care; dissatisfaction with primary care provider; satisfaction with ED; ED accessibility and convenience resulting in low access burden; referred to the ED by others; and relationships between patients and health care providers. DISCUSSION: This integrative review examined patient-reported reasons for attending the ED on a non-urgent basis. The results suggest that ED patients are heterogenous and many factors influence their decision-making. Considering the complexity with which patients live, treating them as a single entity may be problematic. Limiting excessive non-urgent visits likely requires a multi-pronged approach. CONCLUSION: For many ED patients, they have a very clear problem which needed to be addressed. Future studies should explore psychosocial factors driving decision-making (e.g., health literacy, health-related personal beliefs, stress and coping ability).

Evaluation of a modernized supported housing intervention for individuals who experience severe and persistent mental illness in Ontario, Canada.

WHAT IS KNOWN ON THE SUBJECT: Supported housing approaches that include case management and increased opportunities for independence and personal autonomy for people who are living with severe and persistent mental illness (SPMI) have been found to help reduce hospitalizations and use of the emergency department. What is not fully clear is if these types of supported housing arrangements also influence the use of primary health care and other specialist services. WHAT THE PAPER ADDS TO EXISTING KNOWLEDGE: This study uncovered that individuals experiencing SPMI who lived in supported housing used more primary health care and specialist physician services, in the year following transition to this housing arrangement. WHAT ARE THE IMPLICATIONS FOR PRACTICE: The findings of this study suggest that supported housing arrangements for people experiencing SPMI may help in improving the personalization of health services for individual residents, including increasing access to both primary health care and specialist services. This is important for nursing practice, as the findings of the study show that supported housing arrangements for people experiencing SPMI may assist in better supporting their complex health care needs. ABSTRACT: INTRODUCTION: Supported housing for people who are living with severe and persistent mental illness (SPMI) has been found to help reduce hospitalizations and use of the emergency department. What is not fully clear is if these types of supported housing arrangements also influence the use of primary health care and other specialist services. AIM/QUESTION: The aim of this study was to compare the use of health services use of individuals with SPMI, before and after transition to the new supported housing program. METHOD: Using health care administrative databases, a pre-post cohort study was conducted examining the health system use of residents who transitioned from custodial to supported housing arrangements between 2017 and 2019. RESULTS: Individuals with SPMI used more primary health care and specialist physician services after transition to the supported housing model. DISCUSSION: The results suggest that a supported housing model may be associated with increased usage of outpatient person-centred health services in people experiencing SPMI. IMPLICATIONS FOR PRACTICE: The findings of this study suggest that supported housing arrangements for people experiencing SPMI may help in improving the personalization of health services for individual. This is important for nursing practice, as the findings of the study show that supported housing arrangements may assist in better supporting complex health care needs of individuals.

Comparison of environment quality measurements between 3 types of calf housing in the United Kingdom.

Preweaning calves are kept in a range of housing types that offer variable protection against the weather and provide differing internal environments. This cross-sectional observational study assessed the effect of housing type (shed, polytunnel, or hutches) on internal environmental parameters, using 2 blocks of 8-wk measurements from 10 commercial dairy farms in the south of England, covering both summer and winter periods. Continuous measurements for internal and external temperature and humidity were recorded by data logger placed within the calf housing and used to calculate the temperature-humidity index (THI). Weekly point readings were also taken for temperature, humidity, light, air speed, ammonia level, and airborne particulate matter. Airborne bacterial levels were determined at wk 2, 5, and 8 by incubating air samples at 35°C for 24 h in aerobic conditions. Data were analyzed using linear mixed models. Housing type influenced THI significantly in both seasons. In summer, calves were exposed to heat stress conditions (THI ≥72) for 39, 31, and 14 of 46 d in polytunnel housing, hutches, and sheds, respectively. The maximum summer temperature (37.0°C) was recorded in both hutch and polytunnel housing, with sheds remaining consistently cooler (maximum 31.0°C). In winter, the lowest minimum internal temperature recorded was in hutches at -4.5°C, with both the sheds and polytunnel, but not hutches, providing a significant increase in temperature compared with the external environment. Hutches remained ≤ 10°C for 86% of the winter study period. Light levels were reduced in all housing types compared with the external environment. The particulate matter in air that is capable of reaching the lungs (particulate matter <10 µm) was highest in sheds, intermediate in hutches, and lowest in polytunnel housing (0.97 ± 3.75, 0.37 ± 0.44, and 0.20 ± 0.24 mg/m3, respectively). This was mirrored by airborne bacterial numbers, which were also highest in sheds (8,017 ± 2,141 cfu/m3), intermediate in hutches (6,870 ± 2,084 cfu/m3), and lowest in the polytunnel (3,357 ± 2,572 cfu/m3). Round, white, catalase-positive, and oxidase-negative colonies were most prevalent, likely indicating Staphylococcus species. This study demonstrated that UK calves are routinely exposed to either heat or cold stress, especially when housed in hutches or polytunnels. Sheds had the highest levels of particulate matter and airborne bacteria, both known contributory factors for respiratory disease. These findings demonstrate that all calf housing systems result in environmental compromises that could have long-term impacts on calf health and growth; therefore, further studies should identify husbandry and housing modifications to mitigate these factors.

Expertise and information: an epistemic logic perspective.

In this paper we present a modal logic framework to reason about the expertise of information sources. A source is considered an expert on a proposition φ if they are able to correctly refute φ in any possible world where φ is false. Closely connected with expertise is a notion of soundness of information: φ is said to be "sound" if it is true up to lack of expertise of the source. That is, any statement logically weaker than φ on which the source has expertise must in fact be true. This is relevant for modelling situations in which sources make claims beyond their domain of expertise. Particular attention is paid to the connection between expertise and knowledge: we show that expertise and soundness admit precise interpretations in terms of S4 and S5 epistemic logic, under certain conditions. We go on to extend the framework to multiple sources, defining two notions of collective expertise. These also have epistemic interpretations via distributed and common knowledge from multi-agent epistemic logic. On the technical side, we give several sound and complete axiomatisations of various classes of expertise models.
