Abstract Background As the demand for mental health and substance use (MHSU) services increases, there will be an even greater need for health human resources to deliver this care. This study investigates how family physicians’ (FP) contact volume, and more specifically, MHSU contact volume, is shaped by demographic trends among FPs in British Columbia, Canada. Methods We used annual physician-level administrative billing data and demographic information on FPs in British Columbia between 1996 and 2017. This study analyzes trends in primary care service provision among graduating cohorts of FPs, FPs of different ages (as measured by years since graduation), and FPs practicing during different time periods. Additionally, analyses are stratified by FP sex to account for potential differences in labour supply patterns between male and female FPs. Results Our results show that while FPs’ overall contacts with patients decreased between 1996 and 2017, their annual number of MHSU contacts increased, which was largely driven by an increase in substance use visits. Demographically, the proportion of female FPs in the labour force rose over time. Observed trends were similar, though not identical in male and female FPs, as males tended to have higher overall contact volume (both total contacts and MHSU), but also steeper declines in contact volume in later careers. The number of contacts (both total and MHSU) changed across career stage - rising steadily from start to mid-career, peaking at 20–30 years in practice, and decreasing steadily thereafter. This was evident for all cohorts and consistent over the 21-year study period but flattened in amplitude over time. Our findings also point to potential cohort effects on labour supply. The inverse U-shaped career trend extended to MHSU contacts, but its peak seems to have shifted to a later career stage (peaking at 30–40 years of practice) over time. Conclusions Our study shows changing dynamics in MHSU service delivery among FPs over time, across the life span and between FP sexes that are likely to influence access to care beyond simply the number of FPs. Given the healthcare needs of the population, these findings point to potential future changes in provision of MHSU services.

OBJECTIVES: British Columbia (BC), Canada, experienced an unprecedented summer with record-breaking high temperatures in 2021. Yet the health impact has not been examined in occupational settings. This study aimed to characterize occupational heat-related illness (HRI) among BC workers estimated by incidence rates and associations between heatwaves and HRI, compare risks from 2021 and prior summers of 2001–2020, and assess differential impacts on worker groups by demographics and occupations. METHODS: We identified HRI from workers’ compensation claims that occurred between June and August from 2001–2021 in BC. Incidence rates were calculated using working population estimates from Statistics Canada’s Labour Force Survey. A time-stratified case-crossover design with conditional Poisson regression was used to examine the impact of heatwaves on occupational HRI. All analyses were stratified by year (2021 versus 2001–2020), age, sex, and occupation. RESULTS: Of the 521 claims identified, 107 (21%) occurred in 2021. Incidence rates for 2021 and prior summers were 3.97 [95% confidence interval (CI) 3.26–4.80] and 0.93 (95% CI 0.85–1.03) claims per 100 000 workers, respectively. This difference represents a 327% increase. Rates were higher in health occupations in 2021 versus 2001–2020. During 2001–2021, the risk of HRI during heatwave days was 4.33 (95% CI 2.98–6.27) times that during non-heatwave days, and the risk was higher among middle-aged workers and workers in trades, transport, and equipment operations. The 2021 heatwaves had greater impact on younger and female workers than those from prior summers. CONCLUSIONS: Heat is a crucial workplace hazard. Prevention strategies should prioritize at-risk workers and not be limited to heatwaves.

Introduction: For general surgeons practising in rural areas, multiple factors influence care beyond skills learned in residency. The British Columbia Privileging Dictionary (BCPD) defines core and non-core procedures that shape the scope of general surgeons. Moreover, the Royal College has adopted a Competence by Design (CBD) curriculum which employs entrustable professional activities (EPAs) that list surgical skill residents must be proficient in by graduation. Our goal is to understand the current practice patterns of rural general surgeons in BC based on these policies and local factors. Methods: Medical service plan (MSP) data were collected from 2011 to 2021 based on general surgeons working in rural subsidiary agreement (RSA) communities. The MSP fee codes were organised into core or non-core procedures, as outlined by the BCPD. EPAs were assessed and compared to the non-core procedures. Results: From 2011 to 2021, 223,103 procedures were performed in rural sites in BC. On average, 90.97 (standard deviation = 20.78) of procedures done in all communities were BCPD core procedures. The most common non-core surgical care performed by general surgeons was in plastic surgery (n = 8035). Over 8 of procedures performed were not general surgery EPAs. Notably, none of the EPAs are considered non-core privileges and all EPAs have been performed in rural settings. Conclusion: General surgeons working in rural settings perform multiple procedures outside of EPAs which account for over 8 of their caseload and approximately 6 of procedures performed are non-core privileges. This provides some insight into the potential limitations of the BCPD on graduates hoping to practise in rural communities. As the CBD curriculum has been reported to provide a more flexible approach to learning, it may be tailored to suit residents' learning and career goals, including varied surgical skills to suit rural needs. Introduction: Pour les chirurgiens généraux exerçant en zone rurale, de multiples facteurs influencent les soins, et ce au-delà des compétences acquises en résidence. Le British Columbia Privileging Dictionary (BCPD) définit les procédures essentielles et non essentielles qui déterminent le champ d'action des chirurgiens généraux. En outre, le Collège royal a adopté un programme d'études intitulé « La compétence par conception » (CPC) qui utilise des activités professionnelles confiables (APC) qui énumèrent les compétences chirurgicales que les résidents doivent maîtriser avant d'obtenir leur diplôme. Notre objectif est de comprendre les modes de pratique actuels des chirurgiens généralistes ruraux en Colombie-Britannique en fonction de ces politiques et des facteurs locaux. Méthodes: Les données du Medical Service Plan (MSP, Plan de service médical) ont été recueillies entre 2011 et 2021 auprès des chirurgiens généralistes travaillant dans les communautés du « Rural Subsidiary Agreement » (RSA). Les codes d'honoraires du MSP ont été organisés en procédures essentielles ou non essentielles, comme indiqué par le BCPD. Les APC ont été évalués et comparés aux procédures non essentielles. Résultats: Entre 2011 et 2021, 223 103 procédures ont été réalisées dans des sites ruraux en Colombie-Britannique. En moyenne, 90,97 (écart-type = 20,78) des procédures effectuées dans toutes les communautés étaient des procédures de base du BCPD. Les soins chirurgicaux non essentiels les plus courants effectués par les chirurgiens généraux étaient la chirurgie plastique (n = 8035). Plus de 8 des procédures réalisées n'étaient pas des APC de chirurgie générale. Il est à noter qu'aucune des APC n'est considérée comme un privilège non essentiel et que toutes ont été réalisées en milieu rural. Conclusion: Les chirurgiens généraux travaillant en milieu rural pratiquent de nombreuses procédures en dehors de l'APC, représentant plus de 8 de leur charge de travail et environ 6 des procédures pratiquées sont des privilèges non essentiels. Cela donne une idée des limites potentielles du BCPD pour les diplômés qui espèrent exercer dans les communautés rurales. Étant donné que le programme d'études CPC est réputé offrir une approche plus souple de l'apprentissage, il peut être adapté aux objectifs d'apprentissage et de carrière des résidents, notamment en leur permettant d'acquérir des compétences chirurgicales variées pour répondre aux besoins des zones rurales.

Introduction: The COVID-19 pandemic has changed healthcare service delivery. We examined the overall impact of COVID-19 on people living with HIV in British Columbia (BC), Canada, with a special focus on the potential impact of COVID-19 on antiretroviral treatment interruptions (TIs)., Methods: Purposive sampling was used to enrol people living with HIV aged ≥19 years across BC into the STOP HIV/AIDS Program Evaluation study between January 2016 and September 2018. Participants completed surveys at baseline enrolment and 18 and 36 months later. Additional COVID-19 questions were added to the survey in October 2020. TIs were defined as >60 days late for antiretroviral therapy (ART) refill using data from the BC HIV Drug Treatment Program. Generalized linear mixed models were used to examine trends in TIs over time and associations with reported health service access., Results: Of 581 participants, 6.1%-7.7% experienced a TI during each 6-month period between March 2019 and August 2021. The frequency of TIs did not statistically increase during the COVID-19 epidemic. Among the 188 participants who completed the COVID-19 questionnaire, 32.8% reported difficulty accessing healthcare during COVID-19, 9.7% reported avoiding continuing a healthcare service due to COVID-19-related concerns, and 74.6% reported using virtual healthcare services since March 2020. In multivariable analysis, the odds of a TI in any 6-month period were not significantly different from March to August 2019. None of the reported challenges to healthcare services were associated with TIs., Conclusions: Although some participants reported challenges to accessing services or avoidance of services due to COVID-19, TIs were not more likely during COVID-19 than before., (© 2024 The Authors.

Background: People with intellectual/developmental disabilities (IDD) are known to have high rates of prescription drug use, particularly for psychotropic medications. This is of concern due to the many side effects associated with these medications and because of the risks of polypharmacy. In this paper we compare the most commonly dispensed drugs and all psychotropic medications for youth with IDD compared with youth without IDD., Methods: Using population-level administrative health data over a 10-year period, this study examined medications dispensed to youth with an IDD aged 15-24 years compared with youth without an IDD. The most common medications dispensed and the number of youth they were dispensed to were determined. As well a wide variety of psychotropic medications were examined., Results: There were a total of 20 591 youth with IDD and 1 293 791 youth without IDD identified. Youth with IDD had higher odds of being dispensed pain medications, amoxicillin, salbutamol, levothyroxine and all the psychotropic medications (antidepressants, antipsychotics, anxiolytics, anti-adrenergic agents, mood stabilisers and stimulants). For youth with IDD, 6558 (31.85%) were dispensed two or more different psychotropic medications within a year, compared with 75 963 (5.87%) of youth without IDD., Discussion: Compared to youth without IDD, youth with IDD had significantly higher odds of being dispensed most of the prescription medications studied, including all of the psychotropic medications. They were also twice as likely to be dispensed two or more medications from different classes of psychotropic drugs within the same year. These findings have important implications for the health of people with IDD and for their health care providers., (© 2024 John Wiley & Sons and MENCAP.)

We assessed the impact of the COVID-19 pandemic on hepatocellular carcinoma (HCC) surveillance among individuals with HCV diagnosed with cirrhosis in British Columbia (BC), Canada. We used data from the British Columbia Hepatitis Testers Cohort (BC-HTC), including all individuals in the province tested for or diagnosed with HCV from 1 January 1990 to 31 December 2015, to assess HCC surveillance. To analyse the impact of the pandemic on HCC surveillance, we used pre-policy (January 2018 to February 2020) and post-policy (March to December 2020) periods. We conducted interrupted time series (ITS) analysis using a segmented linear regression model and included first-order autocorrelation terms. From January 2018 to December 2020, 6546 HCC screenings were performed among 3429 individuals with HCV and cirrhosis. The ITS model showed an immediate decrease in HCC screenings in March and April 2020, with an overall level change of -71 screenings [95% confidence interval (CI): -105.9, -18.9]. We observed a significant decrease in HCC surveillance among study participants, regardless of HCV treatment status and age group, with the sharpest decrease among untreated HCV patients. A recovery of HCC surveillance followed this decline, reflected in an increasing trend of 7.8 screenings (95% CI: 0.6, 13.5) per month during the post-policy period. There was no level or trend change in the number of individuals diagnosed with HCC. We observed a sharp decline in HCC surveillance among people living with HCV and cirrhosis in BC following the COVID-19 pandemic control measures. HCC screening returned to pre-pandemic levels by mid-2020., (© 2024 The Author(s). Journal of Viral Hepatitis published by John Wiley & Sons Ltd.)

Aim: Integrated youth services (IYS) have been identified as a national priority in response to the youth mental health and substance use (MHSU) crisis in Canada. In British Columbia (BC), an IYS initiative called Foundry expanded to 11 physical centres and launched a virtual service. The aim of the study was to describe the demographics of Foundry clients and patterns of service utilization during this expansion, along with the impact of the COVID-19 pandemic., Methods: Data were analysed for all youth (ages 12-24) accessing both in-person (April 27th, 2018-March 31st, 2021) and virtual (May 1st, 2020-March 31st, 2021) services. Cohorts containing all clients from before (April 27th, 2018-March 16th, 2020) and during (March 17th, 2020-March 31st, 2021) the COVID-19 pandemic were also examined., Results: A total of 23 749 unique youth accessed Foundry during the study period, with 110 145 services provided. Mean client age was 19.54 years (SD = 3.45) and 62% identified as female. Over 60% of youth scored 'high' or 'very high' for distress and 29% had a self-rated mental health of 'poor', with similar percentages seen for all services and virtual services. These ratings stayed consistent before and during the COVID-19 pandemic., Conclusions: Foundry has continued to reach the target age group, with a 65% increase in number of clients during the study period compared with the pilot stage. This study highlights lessons learned and next steps to promote youth-centred data capture practices over time within an integrated youth services context., (© 2024 The Authors.

Aims: The oral health needs of frail older adults are increasing with an aging population in Canada. The objective of this study was to explore the perceptions of dentists in British Columbia regarding their view of geriatric dentistry as a distinct scope of practice and in relation to special needs dentistry., Methods and Results: Qualitative data were gathered thorough semi guided interviews of a purposeful sample of dental clinicians, educators and members of organized dentistry with specialized knowledge of oral health for frail older adults. Interviews were transcribed, coded, and analyzed using a thematic approach. Thematic saturation was reached with the 10 participants in this study. Through the method of interpretative description, patient, dentist, and systemic factors that shaped scope of practice for geriatric dentistry were identified as well as the broader skill sets required for geriatric dentistry., Conclusion: The study found that participants perceived geriatric dentistry as unique scope of practice from general dentistry requiring special knowledge in the management of challenges associated with aging with frailty as well as the ability to work in long-term care. Similar to special needs dentistry, geriatric dentistry requires person-centered care and emphasized the need for interprofessional collaboration in alternative care settings., (© 2024 The Author(s).

Internationalization continues to be a priority of the education mandate in British Columbia (BC). While there is currently a lack of exploratory studies on international students' (IS) experiences of challenges in their host institutions, little research has examined their experiences from sociocultural context-based standpoints. This study fills this gap by examining the daily lived experiences of Chinese postsecondary IS in BC through the lens of intersectionality. First, the notions of cultural distance, nationality, and language proficiency were conceptualized as intersectional categories. Next, narrative data were collected from six Chinese IS and then analyzed through an iterative coding framework that connected narrative themes to the theoretical framework of intersectionality. The results show how the interlocking categories created instances of minoritization among the participants due to power imbalances brought upon by compatriots, peers, and federal/institutional policies. Implications in future directions of intersectionality research, policy, and practices are presented.

This study looked into the lived experiences of international students during the COVID-19 pandemic in Vancouver, British Columbia, Canada. The research focused on how international students viewed the COVID-19 pandemic, their personal, social, economic, health and hygiene, and schooling experiences. A validated and reliable researchers-made questionnaire was used. Weighted means and Fisher's Exact Hypothesis Testing on Association were used to analyze the responses of the international students. The researchers used Fisher's exact test since they wanted to know whether the proportions for one variable were different among values of the other variable. Foreign students had a solid grasp of the potential risks COVID-19 posed and accepted the associated lockdown requirements. The survey results indicated that the students' nationality played a vital role in their perception of their financial health and well-being. Students were insecure with their accommodation, expenses, and scheduling. Lastly, they also felt alone, and economically challenged.

Vertebrate scavengers represent important taphonomic agents that can act on a body, particularly when in an outdoor environment. Understanding the effects of these agents will direct how and where to search for human remains and influence the likelihood of discovery in a particular region. The current study aimed to identify the taphonomic impact of scavenger guilds in the peri-urban and rural regions of southeastern British Columbia. Vertebrate scavenger activity on pig carcasses was recorded remotely using trail cameras and analyzed to determine temporal scavenging profiles. Both the peri-urban and rural environments produced comparable scavenger guilds, namely: turkey vultures, American crows/northern ravens (classified as "corvids"), American black bears, and coyotes. Although the two locations had different study lengths due to variable degrees of scavenging, for the period that was common to both locations (summer to early fall), the black bear was the most frequent scavenger followed by coyote. However, the dispersal of remains by the mammalian scavengers was distinctly different between sites. Only 12%-33% of skeletal elements were recovered at the rural sites compared to 80%-90% recovered at the peri-urban sites, even though the latter sites had a longer study timeframe. The extended timeframe of the peri-urban sites confirmed that certain scavengers (e.g., turkey vultures and black bears) are only seasonally active in this region. These findings demonstrate the variability of scavenger behavior and the need to assign caution and local ecological knowledge when predicting scavenger trends. Such taphonomic information is relevant for human remains searches in regions with comparable scavenger guilds., (© 2024 The Author(s).

Background: Progressive harm reduction policies have been implemented in British Columbia, Canada. However, youth who use drugs face barriers to receiving harm reduction care, resulting in increasing opioid-related hospitalizations and drug toxicity deaths. This scoping review collates peer-reviewed evidence to understand the barriers and facilitators faced by youth who use drugs when accessing harm reduction programming in British Columbia, Canada., Methods: This scoping review entailed conducting a systematic search of relevant databases to identify relevant articles. Articles were included if they: (i) contained youth falling between the ages of 12 and 26 years old; (ii) explored accessibility, barriers, and/or facilitators to harm reduction care or related topics; (iii) were empirical research articles using primary data (i.e., reviews, grey literature, theoretical or conceptual papers, books, etc. were excluded); and (iv) were available in the English language, given the geographic focus on British Columbia., Results: A total of 398 sources were identified and ultimately, data from 13 sources were charted and extracted. When investigating barriers to harm reduction care among youth, four themes emerged: self-stigma, service navigation, service delivery, and negative provider interactions. Furthermore, in exploring factors that facilitate harm reduction care for youth, four themes surfaced: ability to meet basic needs, positive provider interactions, social networks, and risk mitigation guidance., Conclusions: The expansion of harm reduction services in 2016 did not fully address accessibility challenges faced by youth who use drugs. Barriers continue to hinder harm reduction engagement, while supportive networks, positive provider interactions, and the ability to meet basic needs facilitated sustained access. Tailored policy interventions rooted in equity are crucial to improving access to harm reduction services for youth who use drugs., (© 2024. The Author(s).)

This study aimed to synthesise and interpret stable isotopic data ( δ 2 H and δ 18 O) from various sources to understand the isotope hydrology around coal mine operations in Elk Valley, B.C., Canada. The data, including precipitation, groundwaters, seeps, and mine rock drains, were used to construct a local meteoric water line (LMWL) for the Elk Valley, evaluate the spatiotemporal isotopic composition of its groundwater, and assess mine seepage and mine rock drain discharge. The study revealed a robust LMWL relation ( δ 2 H = 7.4 ± 0.2 · δ 18 O - 4.3 ± 4.1). The groundwater and seep data indicated a winter season bias and a north-south latitudinal gradient, suggesting rapid near-surface groundwater flow without significant post-precipitation evaporation. Porewater isotope samples from unsaturated mine rock piles (MRPs) showed site-specific evaporation patterns, potentially due to convective air flows or exothermic sulphide oxidation. This research revealed the influence of groundwater and meltwater on rock drain discharge. Based on evaporative mass balance calculations, MRPs seasonally contributed ca. 5 %(December base flow) and 22 % (snowmelt) to drain discharge. The findings underscore the value of stable isotope data collections in the Elk Valley to help better define and quantify the hydrology-hydrogeology, including a better understanding of evaporative conditions in MRPs.

Given the healthcare needs of the population, these findings point to potential future changes in provision of MHSU services., (© 2024. The Author(s).)

The aim of this qualitative case study is to examine the phenomenon of female students' disproportionate representation in senior level Physical Health Education (PHE) classes. The subject for this teacher's Masters level project arose from the first author's personal observations while teaching across several schools in British Columbia, Canada. Through semi-structured interviews with self-identified female participants, we explore female subject choice and if, along with possible reasons why, females may avoid participation in senior level (grade 11-12) mixed gender PHE activity courses. This discussion asserts that females mostly make conscious choices to avoid mixed gender courses at the senior level for several key reasons; females feel silenced by their male peers, PHE is not an inclusive environment, and females perceive their male counterparts assert dominance over them in PHE class. This paper continues with a discussion regarding reinforced gendered norms and their effect on perceived barriers to female participation in schools, and concludes with suggestions for how schools and educators might support female students' participation.

Introduction: Wildland firefighters are exposed through the lungs and skin to particulate matter, fumes, and vapors containing polycyclic aromatic hydrocarbons (PAH). Wearing respiratory protection should reduce pulmonary exposure, but there is uncertainty about the most effective and acceptable type of mask., Methods: Firefighters from 6 unit crews working with the British Columbia Wildfire Service were approached and those consenting were randomly allocated within each crew to a "no mask" control group or to use 1 of 3 types of masks: X, half-face respirator with P100/multi gas cartridge; Y, cloth with alpaca filter; Z mesh fabric with a carbon filter. Crews were followed for 3 consecutive firefighting days. The mask allocated was constant for each firefighter throughout. All participants completed a brief questionnaire at the start and end of each day, giving information on mask use, respiratory symptoms, and assessment of mask qualities. Spot urine samples were collected pre and post shift to assess 1-hydroxypyrene (1-HP) concentration as an indicator of total PAH absorption. Skin wipe samples from the hands and throat were collected pre and post shift and analyzed for PAH concentration. On each day monitored, 4 participants carried sampling pumps to measure total particulates and PAHs on particles and in vapor phase. The primary outcome was the concentration of urinary 1-HP at the end of the fire day. Secondary outcomes were changes in respiratory and eye symptoms during the course of the shift, reported mask use, and perception of mask qualities. The analysis used a 3-level random intercept regression model that clustered observations within individuals and crews. We aimed to detect any relation of allocated mask type to the 4 outcomes, having allowed for estimated exposure., Results: Information was collected from 89 firefighters, including 14 women: 49% (37/75) of male firefighters were bearded. Nineteen fire days were monitored for a total of 263 firefighter × days, 64 to 68 for each intervention group. The end of shift 1-HP was higher than the start of the shift. Urinary 1-HP was more strongly related to PAHs on the skin than in the breathing zone. Men with beards had higher end-of-shift urinary log 1-HP/creat (ng/g) than other firefighters. None of the groups allocated a mask had lower 1-HP than the no-mask group, either in the study group overall or when stratified by beard-wearing. Among those without either beards or a failed fit-test, Mask Z reduced at the end of shift 1-HP where airborne PAH concentration was high. End-of-shift symptoms were related to particle mass in the breathing zone but was not mitigated by any of the masks. Hours electing not to wear a mask increased from the first to third shift for all mask types. Mask Z was rated as more comfortable than other types. Mask X was rated highest on fit and perceived protection. Mask Y gained the lowest ratings on fit, comfort and feelings of protection., Conclusions: Allocated masks did not provide protection overall, but the results highlighted the need for a wider understanding of the circumstances in which wearing efficient protection is well-advised., (© The Author(s) 2024.

Objectives: There are health disparities and inequities in the outcomes of critical illness survivors related to the influence of social determinants of health on recovery. The purpose of this study was to describe the relationship between critical illness recovery and the intermediary social determinants of health in the Canadian context. Because Canadian healthcare is provided within a universal publicly funded system, this analysis sheds light on the role of social determinants of health in the context of universal health services and a relatively robust social safety net., Design: In this qualitative interpretive description study, data from semi-structured interviews with intensive care unit survivors, family caregivers and healthcare providers were analysed using thematic and constant comparative methods., Setting: Western Canadian Hospital serving a population of 900 000 people., Participants: The 74 study participants included 30 patients (mean age 58 years, 18 men and 12 women) and 25 family caregivers (mean age 55 years, 8 men and 17 women), representing 37 cases, as well as 19 healthcare providers., Results: Challenges with employment and finances, home set-up, transportation, food and nutrition, medications and social support complicated and hindered critical illness recovery. Critical illness sequelae also altered these social determinants of health, suggesting a reciprocal relationship. Furthermore, individuals experiencing socioeconomic disadvantage before critical illness described being at a greater disadvantage following their critical illness, which interfered with their recovery and suggests an accumulation of risk for some., Conclusions: Our findings underscore the significant influence of social determinants of health on critical illness recovery, highlighting the importance of creating and evaluating comprehensive approaches to health and well-being that address health inequities., Competing Interests: Competing interests: RCA has received honoraria from Edwards Lifesciences and HLS Therapeutics.

Climate change has significantly impacted the wildfire regimes in lodgepole pine forests, resulting in prolonged fire seasons and altered fire behaviour. In North America, fire patterns have shifted towards more frequent and severe wildfires after a century of fire suppression. In response, silviculture practices in fire-prone areas should aim to restore diverse forest structures that are resistant or resilient to wildfires. In Western Canada, where forestry is a key industry, interest in seeking silvicultural solutions for promoting forest resilience to wildfires has increased following the devastating wildfire seasons between 2017 and 2023. Irregular shelterwood, a silvicultural system with a relatively short history of implementation in British Columbia, has been deployed in ecologically sensitive areas to promote structural heterogeneity and meet management goals for biodiversity and wildlife values. Although the impacts of irregular shelterwood on wildlife habitat and abundance have been well studied, the interaction between wildfire and the stand structure created by irregular shelterwood remains poorly understood. To understand the effectiveness of the irregular shelterwood in building wildfire resilience, we present a study of a lodgepole pine stand that was treated with irregular shelterwood and partially burned in a wildfire in 2017. This study collected ground fuel, canopy fuel, and tree data from four stand types (irregular shelterwood treated-burnt, treated-unburnt, untreated-burnt, and untreated-unburnt) and analyzed the difference in char height and fire-induced mortality between burnt and unburnt conditions, with irregular shelterwood treatment being a variable. The results demonstrated reduced wildfire effect in the irregular shelterwood stand in this region of British Columbia. This observation was made at a stage where the openings have not been colonized by regeneration. This case study provides valuable insights into the effectiveness of irregular shelterwood in mitigating wildfire risk, and proposes a potential silviculture solution to promote forest resilience to wildfire., Competing Interests: NO authors have competing interests., (Copyright: © 2024 Liu et al.

Objectives: To summarise PEEP's (Professionals for Ethical Engagement of Peers-a group of consultants with lived and living experience of substance use) outputs and gain insights into PEEP's impact and suggestions for the future., Design: Included an environmental scan to collate PEEP activities and outputs and a participatory qualitative design using thematic analysis., Setting: British Columbia, Canada., Participants: Eight members of PEEP and nine staff/people who consulted PEEP were interviewed., Results: PEEP members are co-authors/acknowledged for their input in 25 peer review publications and 16 reports; PEEP members co-presented or were co-authors on 33 presentations. PEEP meets by Zoom two times per week and is paid monthly via honorarium from the Provincial Health Service Authority at a current rate of $C30 per hour. Four themes emerged from our interviews: (1) What is PEEP? (PEEP provides a sense of community, holds systems accountable and inspires others), (2) PEEP Process (suggestions for improvement: consultants should be prepared and involve PEEP throughout the process and report how PEEP's insights were used), (3) PEEP Outcomes (PEEP members gain skills and confidence, PEEP provides a reality check, consultants learn from PEEP, and input leads to practice changes) and (4) Future of PEEP (sustainable funding and opportunities for growth are critical)., Conclusion: PEEP is a cohesive group whose input is well-respected and influences policy and programmes. Given the ongoing drug toxicity emergency, it is critical to continue to support and expand PEEP., Competing Interests: Competing interests: JAB was involved in the initial creation of PEEP; KL, CB, PC, EH, IH, JL, JM and KS are current staff or members of PEEP. KD and AD have no competing interests., (© Author(s) (or their employer(s)) 2024. Re-use permitted under CC BY-NC. No commercial re-use. See rights and permissions. Published by BMJ.)

Background: Substance use during pregnancy is underreported globally and there is limited data on its prevalence and the availability of supportive services. This study determined population perinatal substance use in British Columbia (BC) by region and examined the availability of clinical and community-based programs., Methods: Using linked provincial health administrative data, we conducted a population-based retrospective cohort study including all BC residents accessing care for substance use (alcohol, opioids, stimulants, sedatives, and cannabis) within 12 months of first perinatal care record to delivery during 2016-2021. We also conducted an environmental scan to identify all programs offering perinatal care and substance use treatment/support in BC as of December 2022 and described program components by region., Results: The population included 12,439 people with perinatal substance use with 13,814 linked livebirths during the study period. The incidence rate of perinatal substance use was nearly eight times higher in rural/remote Northern BC compared to the metropolitan Vancouver Coastal region (1044.2 vs. 131.3 per 100,000 population, respectively). We identified 29 related services (19 wrap-around programs, 8 supportive housing, and only 2 acute care programs). Residents outside of Metro Vancouver accounted for 60 % (N=1745) of people with perinatal substance use; however, these regions represented only 35 % of BC's specialized acute care and supportive housing beds (N=140)., Conclusions: Expanding supports for perinatal substance use - particularly acute care and supportive housing within more rural/remote regions in BC - will be critical to address geographic inequities in access to perinatal care and improve health outcomes for pregnant people who use substances and their infants., Competing Interests: Declaration of Competing Interest No conflict declared., (Copyright © 2024 The Authors.

In 2017, British Columbia (BC) transferred responsibility for healthcare services in provincial correctional facilities from the Ministry of Public Safety and Solicitor General to the Ministry of Health. This study explored how healthcare leadership perceived the impact of the transfer on services, work-life, and job satisfaction. We conducted one-on-one interviews ( n = 8) with healthcare managers and medical and administrative leadership within Correctional Health Services. Using the Two-Factor theory of job satisfaction as a framework, we applied Interpretive Description methodology to analyse interview data. Participants identified changes to four areas of the working environment: (1) staffing, equipment, and resources (2) systems of supervision and support (3) standards, policies, and quality improvement and (4) culture and orientation. These changes predominantly affected motivational factors of job satisfaction and were described as enriching the roles of managers and staff. Participants described improved autonomy and recognition of providers, increased quality of services delivered, and a shift toward patient-centred care. The perspectives of healthcare leaders provide new insight into the potential impact of transferring healthcare services in custody to a public healthcare system. Discussion of changes and their affects also provide practical learning for jurisdictions seeking to improve healthcare under a variety of governance and service-delivery models., Competing Interests: Declaration of conflicting interestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Background: Morbidity and mortality related to substance use have risen to catastrophic levels in North America, and treatment services are often difficult to access. In response, the province of British Columbia (BC), Canada, launched a province-wide addiction medicine support phone line that offers clinicians immediate access to phone consultation with an addictions medicine expert. The service operates 24/7 is accessible to any clinician in the province seeking assistance with an addiction-related question. We describe an evaluation of the reach and perceived impact of the service over its first two years., Methods: The 24/7 Addiction Medicine Clinician Support Line was evaluated prospectively from June 2020 to April 2022. All provider-to-provider encounters were included. Data was collected from two primary sources: health provider demographic information collected at the time of consultation, and optional clinician surveys conducted after the consultation was complete. Descriptive data are presented as numerical values and percentages., Results: Over the 22-month evaluation period, 1,279 consultations were requested by 631 distinct care providers across British Columbia. The service averaged 15 calls per week across the province, and 51.5% of calls were made outside of business hours. Physicians made the majority of calls to the service (n = 865, 67.6%), followed by nurse practitioners (n = 162, 12.7%). Among those who completed a follow-up survey (n = 258 calls, 20.2% total calls), 81.8% (n = 211) were "very" or "extremely" satisfied with the consultation. Of these respondents, 65.5% (n = 169) reported that the consultation led to the provision of better care for their patient, with 58.1% (n = 150) initiating a new prescription and 22.1% (n = 57) reporting expedited treatment for their patient. The consultation area of focus was most commonly opioid use (n = 417; 59.6%), followed by polysubstance use (n = 98; 14.0%)., Conclusions: The impact of the 24/7 Addiction Clinician Support Line was widespread, and the service increased accessibility to evidence-based addictions treatment across a range of care settings. Clinicians expressed a high degree of satisfaction with the service. To our knowledge, this province-wide program is the first of its kind in North America, offering a scalable and adaptable model to support access to evidence-based addictions care in under-resourced settings., (© 2024.

Background: With a diverse geographic and sociocultural landscape, Vancouver Coastal Health (VCH) Authority (British Columbia, Canada) encompasses both urban and rural regions, providing a case study to examine the delivery of care services for asthma and chronic obstructive pulmonary disease (COPD). To better understand the landscape of care services within VCH, we aimed to (1) identify asthma and COPD care services availability in urban and rural communities and (2) identify where asthma and COPD quality improvement (QI) initiatives were implemented and their implementation-related characteristics. Methods: An environmental scan was conducted to identify asthma and COPD care services provided in VCH communities. A literature review was conducted to determine where VCH asthma and COPD QI initiatives were implemented and identify their implementation-related characteristics. This case study was analysed descriptively and summarised in tables and figures. Results: The environmental scan analysis revealed that specialty outpatient care, pulmonary rehabilitation, respiratory education and clinical smoking cessation services were limited in urban and unavailable in rural VCH communities. Spirometry services were limited in urban and rural VCH communities. Cross-referencing recommendations from asthma and COPD clinical practice guidelines against prevalence data, we estimated that rural VCH communities could provide 0%-23% of required spirometry while urban could provide 40%-75%. Further, of the 16 asthma and COPD QI initiatives identified within 21 papers, none were conducted at rural VCH healthcare sites. Conclusion: Our findings suggest rural VCH communities have lower access to asthma and COPD care services and the limited urban care services were insufficient to make up for this difference. Past asthma and COPD QI initiatives have not apparently translated to care service improvements in rural regions. Future QI initiatives should focus on overcoming barriers to conducting and participating in QI to improve urban and rural regions' access to asthma and COPD care services., Competing Interests: The authors declare no conflicts of interest., (Copyright © 2024 Amelia Choy et al.)

Objectives: On January 31, 2023, a three-year exemption from the Controlled Drugs and Substances Act was granted to the Canadian province British Columbia (BC), allowing the cumulative possession of 2.5 g of specific unregulated drugs amongst adults. The goals of the policy are to reduce health, social, and economic harms associated with criminalization, stigma, drug overdose deaths, as well as drug seizures, arrests, and associated enforcement and court costs. As the inaugural year has passed, we aimed to assess people who use drugs' awareness and knowledge of the, as well as the policy's impact on their drug use patterns and overdose risk., Methods: We conducted 100 telephone-based semi-structured interviews with people who use drugs from across BC, exploring changes in drug use experiences and perceived overdose risk since the implementation of the policy. Participants also completed an interviewer-administered survey assessing socio-demographics and substance use patterns. We utilized a qualitative content analysis approach to analyze the interview data., Results: Our findings indicate a general awareness of the policy among participants, although some policy details were often misunderstood, and participants expressed the need for more widespread dissemination of policy information. While the majority of participants reported that their drug use patterns remained unchanged after decriminalization, some made subtle adjustments, such as carrying under the 2.5 g threshold to minimize the risk of criminalization. Participants highlighted several policy benefits and concerns, including its potential to reduce criminalization and stigmatization, but also increase public drug consumption. Participants offered suggestions for policy improvement., Conclusion: These findings underscore the need for ongoing monitoring of the impacts of decriminalization regarding its potential impact on people who use drugs' drug use patterns and related risks. Reevaluation of the possession threshold and efforts to enhance education and awareness about the policy could help achieve the policy's goals., (© 2024. The Author(s).)

Background: Prior research has shown that patients with stable ischemic heart disease who undergo delayed coronary artery bypass graft (CABG) surgery face higher mortality rates than those who receive CABG within the time recommended by physicians. However, this research did not account for percutaneous coronary intervention (PCI), a widely available alternative to delayed CABG in many settings. We sought to establish whether there was a difference in mortality between timely PCI and delayed CABG., Methods: We identified 25,520 patients 60 years or older who underwent first-time non-emergency revascularization for angiographically-proven, stable left main or multi-vessel ischemic heart disease in British Columbia between January 1, 2001, and December 31, 2016. We estimated unadjusted and adjusted mortality after index revascularization or last staged PCI for patients undergoing delayed CABG compared to timely PCI., Findings: After adjustment with inverse probability of treatment weights, at three years, patients who underwent delayed CABG had a statistically significant lower mortality compared with patients who received timely PCI (4.3% delayed CABG, 13.5% timely PCI; risk ratio 0.32, 95% CI 0.24-0.40)., Interpretation: Patients who undergo CABG with delay have a lower risk of death than patients who undergo PCI within appropriate time. Our results suggest that patients who wish to receive CABG as their revascularization treatment will receive a mortality benefit over PCI as an alternative strategy., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2024 Hardiman et al.

Background: On January 31st, 2023, the province of British Columbia (BC), Canada, was granted a federal exemption allowing adults (aged 18 +) to possess up to 2.5 g of select illicit drugs. The exemption will be in place for three years (2023-2026), marking the first formal decriminalization of illicit drug policy reform in Canada. BC's decriminalization initiative is premised on several goals. This project seeks to evaluate each of these goals and their individual and combined contributions to determine the overall success of this policy., Methods: The following protocol paper provides a detailed outline of a five-year (2022-2027) national evaluation of BC's decriminalization initiative, as well as the specific objectives, methodologies, and planned analyses for eight interrelated sub-studies that comprise the evaluation. These sub-studies fall under the following five topical areas of research: 1) people who use drugs (PWUD), 2) the police and the criminal justice system, 3) the general public, 4) the health services system, and 5) an economic analysis. Additional research activities may also be explored., Results: The overall evaluation and specific sub-study designs were informed by intensive stakeholder engagement. The evaluation was developed in collaboration with an international expert committee who came together to undertake a nominal group technique to decide on the final evaluation design and corresponding logic model. The evaluation will also employ an advisory board and individual sub-study working groups comprised of experts and PWUD who will oversee the development and implementation of the overall evaluation as well as each sub-study., Discussion: This evaluation will draw on implementation science research practices to evaluate and understand the full impacts of this novel drug policy experiment. Results will be widely disseminated through manuscripts, reports, presentations, and infographics, which will be adapted and tailored for specific audiences. The protocol identifies several anticipated challenges and limitations. This evaluation's evidence-based findings will be poised to offer pivotal insights that can shape and refine the discourse on drug policy and will serve as a critical resource for understanding the multifaceted impacts of decriminalization., (© 2024.
