Factors associated with obtaining prescribed safer supply among people accessing harm reduction services: findings from a cross-sectional survey.

BACKGROUND: With growing rates of unregulated drug toxicity death and concerns regarding COVID-19 transmission among people who use drugs, in March 2020, prescribed safer supply guidance was released in British Columbia. This study describes demographic and substance use characteristics associated with obtaining prescribed safer supply and examines the association between last 6-month harm reduction service access and obtaining prescribed safer supply. METHODS: Data come from the 2021 Harm Reduction Client Survey administered at 17 harm reduction sites across British Columbia. The sample included all who self-reported use of opioids, stimulants, or benzodiazepines in the prior 3 days (N = 491), given active use of these drugs was a requirement for eligibility for prescribed safer supply. The dependent variable was obtaining a prescribed safer supply prescription (Yes vs. No). The primary independent variables were access to drug checking services and access to overdose prevention services in the last 6 months (Yes vs. No). Descriptive statistics (Chi-square tests) were used to compare the characteristics of people who did and did not obtain a prescribed safer supply prescription. Multivariable logistic regression models were run to examine the association of drug checking services and overdose prevention services access with obtaining prescribed safer supply. RESULTS: A small proportion (n = 81(16.5%)) of the sample obtained prescribed safer supply. After adjusting for gender, age, and urbanicity, people who reported drug checking services access in the last 6 months had 1.67 (95% CI 1.00-2.79) times the odds of obtaining prescribed safer supply compared to people who had not contacted these services, and people who reported last 6 months of overdose prevention services access had more than twice the odds (OR 2.08 (95% CI 1.20-3.60)) of prescribed safer supply access, compared to people who did not access these services. CONCLUSIONS: Overall, the proportion of respondents who received prescribed safer supply was low, suggesting that this intervention is not reaching all those in need. Harm reduction services may serve as a point of contact for referral to prescribed safer supply. Additional outreach strategies and service models are needed to improve the accessibility of harm reduction services and of prescribed safer supply in British Columbia.

Spatial-temporal trends in the risk of illicit drug toxicity death in British Columbia.

BACKGROUND: Illicit drug poisoning (overdose) continues to be an important public health problem with overdose-related deaths currently recorded at an unprecedented level. Understanding the geographic variations in fatal overdose mortality is necessary to avoid disproportionate risk resulting from service access inequity. METHODS: We estimated the odds of fatal overdose per event from all cases captured by the overdose surveillance system in British Columbia (2015 - 2018), using both conventional logistic regression and Generalized Additive Models (GAM). The results of GAM were mapped to identify spatial-temporal trends in the risk of fatal overdose. RESULTS: We found that the odds of fatal overdose were about 30% higher in rural areas than in large urban centers, with some regions reporting odds 50% higher than others. Temporal variations in fatal overdose revealed an increasing trend over the entire province. However, the increase occurred earlier and faster in the Interior and Northern regions. CONCLUSION: Rural areas were disproportionately affected by fatal overdose; lack of access to harm reduction services may partly explain the elevated risk in these areas.

The Impact of Demographic, Clinical, and Institutional Factors on Psychiatric Inpatient Length-of-Stay.

The average length of inpatient stay (LOS) for psychiatric care has declined substantially across Canada and the United States during the past two decades. Although LOS is based presumably on patient, hospital, and community factors, there is little understanding of how such factors are linked with LOS. The purpose of this study was to explore potential individual and systemic factors associated with LOS in a large-scale, longitudinal dataset. Study participants consisted of individuals 11 years of age and older admitted for psychiatric conditions to a New Brunswick hospital between April 1, 2003 and March 31, 2014 (N = 51,865). The study used a retrospective cohort design examining data from the New Brunswick Discharge Abstract Database, administrative data comprised of all inpatient admissions across provincial hospitals. Hierarchical regression analysis was used to estimate the association of individual, facility, and system-level factors with psychiatric LOS. Results indicated that hospital-level factors and individual-level characteristics (i.e., discharge disposition, aftercare referral, socioeconomic status (SES)) account for significant variability in LOS. Consistent with extant literature, our results found that hospital, clinical, and individual factors together are associated with LOS. Furthermore, our results highlight demographic factors surrounding living situation and available financial supports, as well as the match or mismatch between preferred language and language in which services are offered.

Convenience and comfort: reasons reported for using drugs alone among clients of harm reduction sites in British Columbia, Canada.

BACKGROUND: North American communities are severely impacted by the overdose crisis, particularly in British Columbia (BC), which has the highest toxic drug overdose death rate in Canada. Most fatal overdoses in BC occurred among individuals using alone and in private residences. This study aimed to assess prevalence and reasons for using drugs alone among people accessing harm reduction services in BC. METHODS: We recruited harm reduction supply distribution site clients from 22 communities across BC. Descriptive statistics and multivariable logistic regression were used to describe factors associated with using alone. Thematic analysis of free-text responses providing reasons for using alone were grouped with survey data and additional themes identified. RESULTS: Overall, 75.8% (n = 314) of the study sample (N = 414) reported using drugs alone within the last week. Those that reported using alone did not differ from those that did not by gender, age, urbanicity, or preferred drug use method. Among those that used alone, 73.2% (n = 230) used opioids, 76.8% (n = 241) used crystal meth, 41.4% (n = 130) used crack/cocaine, and 44.6% (n = 140) used alcohol in the past week. Polysubstance use involving stimulants, opioids, and/or benzodiazepines was reported by 68.5% (n = 215) of those that used alone. Additionally, 22.9% (n = 72) of those that used alone had experienced an opioid and/or stimulant overdose in the past 6 months. In a multivariable logistic regression model, having no regular housing and past week crack/cocaine use were associated with using alone (adjusted odds ratio (AOR): 2.27; 95% CI 1.20-4.27 and AOR: 2.10; 95% CI 1.15-3.82, respectively). The most common reason reported for using alone was convenience and comfort of using alone (44.3%). Additional reasons included: stigma/hiding drug use (14.0%); having no one around (11.7%); safety (9.6%); and not wanting to share drugs with others (8.6%). CONCLUSIONS: Using drugs alone, particularly for convenience and comfort, is ubiquitous among people accessing harm reduction services. Overdose prevention measures that go beyond individual behaviour changes, including providing a safer supply of drugs and eliminating stigma, are paramount to mitigate harms. These interventions are especially necessary as emergence of coronavirus disease may further exacerbate unpredictability of illicit drug content and overdose risk.

Longitudinal examination of youth readmission to mental health inpatient units.

OBJECTIVE: Significant barriers exist for youth in obtaining mental health services. These barriers are exacerbated by growing demand, attributed partially to children and adolescents who have repeat hospital admissions. The purpose of this study was to identify demographic, socioeconomic and clinical predictors of readmission to inpatient psychiatric services in New Brunswick, Canada. METHOD: Key demographic, support and clinical predictors of readmission were identified. The New Brunswick Discharge Abstract Database (DAD) was used to compile a cohort of all children and adolescents ages 3-19 years with psychiatric hospital admissions between 1 April 2003 and 31 March 2014 (N = 3825). Primary analyses consisted of Kaplan-Meier survival methods with log-rank tests to assess time-to-readmission variability, and Cox regression to identify significant predictors of readmission. RESULTS: In total, 27.8% of admitted children and adolescents experienced at least one readmission within the 10-year period, with 57.3% readmitted to hospital within 90 days following discharge. Bivariate results indicated that male, upper-middle socioeconomic status (SES) youths aged 11-15 years from nonrural communities were most likely to be readmitted. Notable predictors of increased readmission likelihood were older age, being male, higher SES, referral to care by medical practitioner, discharge to another health facility, psychosis, and previous psychiatric admission. CONCLUSION: A significant portion of the variance in readmission was accounted for by youth demographic characteristics (i.e. age, SES, geographic location) and various support structures, including referrals to inpatient care and aftercare support services. KEY PRACTITIONER MESSAGE: Readmission to inpatient psychiatric care among youth is affected by a number of multifaceted risk factors across individual, environmental and clinical domains. This study used provincial population-scale longitudinal administrative data to demonstrate the influence of various individual and demographic factors on likelihood of readmission, which is notably absent from the majority of studies that make use of smaller, short-term data samples. Ensuring that multiple factors outside of the clinical context are considered when examining readmission among youth may contribute to a more thorough understanding of youth hospitalization patterns.

Comparing Strategies for Providing Child and Youth Mental Health Care Services in Canada, the United States, and The Netherlands.

This paper reviews how child and youth mental health care services in Canada, the United States, and the Netherlands are organized and financed in order to identify systems and individual-level factors that may inhibit or discourage access to treatment for youth with mental health problems, such as public or private health insurance coverage, out-of-pocket expenses, and referral requirements for specialized mental health care services. Pathways to care for treatment of mental health problems among children and youth are conceptualized and discussed in reference to health insurance coverage and access to specialty services. We outline reforms to the organization of health care that have been introduced in recent years, and the basket of services covered by public and private insurance schemes. We conclude with a discussion of country-level opportunities to enhance access to child and youth mental health services using existing health policy levers in Canada, the United States and the Netherlands.

Primary health care utilization for alcohol-attributed diseases in British Columbia Canada 2001-2011.

BACKGROUND: The purpose of this study was to determine whether general practitioner visits for alcohol-attributed diseases increased in a decade when several regulatory changes were made to the distribution and price of alcohol in British Columbia Canada. METHODS: General practitioner consultations for alcohol-attributed diseases were examined using data from British Columbia's Medical Services Plan database. Negative binomial regression was used to measure the significance of yearly variations using incidence rate ratios by disease type per year. RESULTS: From 2001 to 2011, 690,401 visits were made to general practitioners by 198,623 persons with alcohol-attributed diseases. Most visits (86.2%) were for alcohol dependency syndrome (N = 595,371). General practitioner visits for alcohol-attributed diseases increased significantly (p < .001) by 53.3% from 14,882 cases in 2001 to 22,823 cases in 2011. While the number of cases increased from 2001-2011, the frequency of visits to general practitioners significantly decreased from 3.9 in 2001 to 2.7 visits per case in 2011 (F = 428.1, p < .001). CONCLUSION: From 2001 to 2011 there were significant increases in the number of persons presenting to general practitioners with alcohol-attributed diseases in British Columbia. The results of this study demonstrate the need to provide enhanced support to general practitioners in the treatment of patients with substance use disorders given the increasing number of primary health care patients with alcohol-attributed diseases.

The Role of Gender and Income in Predicting Barriers to Mental Health Care in Canada.

There have been traditionally low rates of health care utilization by persons with mental health issues in developed countries such as Canada due to barriers that discourage health care service use such as waitlists, long distances to health services, and stigma that can be associated with seeking help for mental health issues. This project examined barriers to mental health care using data from the Canadian Community Health Survey (N = 4,134) to understand gender and income-related disparities in access to mental health care services. Data were modeled using logistic regression to determine whether gender and household income predicted experiencing barriers to care. There were significant variations in the barriers to care reported by gender and income. Both men and women from low-income (<$29,999) households were significantly more likely to report all types of barriers to care. Men were much more likely to report 'acceptability' barriers to care that related to their perceptions of mental health issues and usefulness of health care services, whereas women were much more likely to report availability or accessibility issues such as a lack of transportation or childcare. The findings of this study demonstrate that despite universal health insurance, there are significant inequities in access to mental health care for low-income Canadians and differences in the types of barriers to care experienced by gender.

Drug overdose and the risk of cardiovascular diseases: a nested case-control study.

BACKGROUND: North America has been experiencing an unprecedented epidemic of drug overdose. This study investigated the associations of drug overdose with the risk of cardiovascular disease (CVD) and 11 major CVD subtypes. METHODS: This nested case-control study was based on a cohort of 20% random sample of residents in British Columbia, Canada, who were aged 18-80 years and did not have known CVD at baseline (n = 617,863). During a 4-year follow-up period, persons who developed incident CVD were identified as case subjects, and the onset date of CVD was defined as the index date. For each case subject, we used incidence density sampling to randomly select up to five control subjects from the cohort members who were alive and did not have known CVD by the index date, were admitted to an emergency department or hospital on the index date for non-CVD causes, and were matched on age, sex, and region of residence. Overdose exposure on the index date and each of the previous 5 days was examined for each subject. RESULTS: This study included 16,113 CVD case subjects (mean age 53 years, 59% male) and 66,875 control subjects. After adjusting for covariates, overdose that occurred on the index date was strongly associated with CVD [odds ratio (OR), 2.9; 95% confidence interval (CI), 2.4-3.5], especially for arrhythmia (OR, 8.6; 95% CI, 6.2-12.0), ischemic stroke (OR, 5.3; 95% CI, 2.0-14.1), hemorrhagic stroke (OR, 3.1; 95% CI, 1.2-8.3), and myocardial infarction (OR, 3.0; 95% CI, 1.5-5.8). The CVD risk was decreased but remained significantly elevated for overdose that occurred on the previous day, and was not observed for overdose that occurred on each of the previous 2-5 days. CONCLUSIONS: Drug overdose appears to be associated with increased risk of cardiovascular diseases.

Association between toxic drug events and encephalopathy in British Columbia, Canada: a cross-sectional analysis.

BACKGROUND: Encephalopathy can occur from a non-fatal toxic drug event (overdose) which results in a partial or complete loss of oxygen to the brain, or due to long-term substance use issues. It can be categorized as a non-traumatic acquired brain injury or toxic encephalopathy. In the context of the drug toxicity crisis in British Columbia (BC), Canada, measuring the co-occurrence of encephalopathy and drug toxicity is challenging due to lack of standardized screening. We aimed to estimate the prevalence of encephalopathy among people who experienced a toxic drug event and examine the association between toxic drug events and encephalopathy. METHODS: Using a 20% random sample of BC residents from administrative health data, we conducted a cross-sectional analysis. Toxic drug events were identified using the BC Provincial Overdose Cohort definition and encephalopathy was identified using ICD codes from hospitalization, emergency department, and primary care records between January 1st 2015 and December 31st 2019. Unadjusted and adjusted log-binomial regression models were employed to estimate the risk of encephalopathy among people who had a toxic drug event compared to people who did not experience a toxic drug event. RESULTS: Among people with encephalopathy, 14.6% (n = 54) had one or more drug toxicity events between 2015 and 2019. After adjusting for sex, age, and mental illness, people who experienced drug toxicity were 15.3 times (95% CI = 11.3, 20.7) more likely to have encephalopathy compared to people who did not experience a drug toxicity event. People who were 40 years and older, male, and had a mental illness were at increased risk of encephalopathy. CONCLUSIONS: There is a need for collaboration between community members, health care providers, and key stakeholders to develop a standardized approach to define, screen, and detect neurocognitive injury related to drug toxicity.

Risk of cardiovascular diseases in relation to substance use disorders.

BACKGROUND: Substance use disorder (SUD) has become increasingly prevalent worldwide, this study investigated the associations of SUD and alcohol, cannabis, opioid, or stimulant use disorder with cardiovascular disease (CVD) and 11 major CVD subtypes. METHODS: This study was based on a 20% random sample of residents in British Columbia, Canada, who were aged 18 - 80 years at baseline on January 1, 2015. Using linked administrative health data during 2010 - 2014, we identified people with various SUDs and prevalent CVDs at baseline, and examined the cross-sectional associations between SUDs and CVDs. After excluding people with CVDs at baseline, we followed the cohort for 4 years to identify people who developed incident CVDs, and examined the longitudinal associations between SUDs and CVDs. RESULTS: The cross-sectional analysis at baseline included 778,771 people (mean age 45 years, 50% male), 13,279 (1.7%) had SUD, and 41,573 (5.3%) had prevalent CVD. After adjusting for covariates, people with SUD were 2.7 (95% confidence interval [CI], 2.5 - 2.8) times more likely than people without SUD to have prevalent CVD. The longitudinal analysis included 617,863 people, 17,360 (2.8%) developed incident CVD during the follow-up period. After adjusting for covariates, people with SUD were 1.7 (95% CI, 1.6 - 1.9) times more likely than people without SUD to develop incident CVD. The cross-sectional and longitudinal associations were more pronounced for people with opioid or stimulant use disorder. CONCLUSIONS: People with SUD are more likely to have prevalent CVD and develop incident CVD compared with people without SUD.

Use of community healthcare and overdose in the 30 days following release from provincial correctional facilities in British Columbia.

BACKGROUND: Interruptions in healthcare services contribute to an elevated risk of overdose in the weeks following release from incarceration. This study examined the association of use of community healthcare with nonfatal and fatal overdose in the 30 days following release. METHODS: We conducted a retrospective cohort study using linked administrative data from a random sample of 20% of the population of British Columbia. We examined releases from provincial correctional facilities between January 1, 2015-December 1, 2018. We fit multivariate Andersen-Gill models to examine nonfatal overdoses after release from incarceration and applied Standard Cox regression for analyses of fatal overdoses. RESULTS: There were a combined 16,809 releases of 6721 people in this study. At least one overdose occurred in 2.8% of releases. A community healthcare visit preceded the first nonfatal overdose in 86.4% of releases with a nonfatal overdose event. Only 48.4% of people who had a fatal overdose used community healthcare. In adjusted analysis, people who had used community healthcare had a higher hazard of healthcare-attended nonfatal overdose (aHR 2.83 95% CI 2.13, 3.78) and lower hazard of fatal overdose (aHR 0.58, 95%CI 0.28, 1.19). CONCLUSIONS: Community healthcare visits after release from custody may be an important opportunity to provide overdose prevention and harm reduction supports. Policies and resourcing are needed to facilitate better connection to primary healthcare during the transition to community. Providers in community should be equipped to offer care to people who have recently experienced incarceration in a way that is accessible, acceptable and trauma-informed.

Periods of altered risk for non-fatal drug overdose: a self-controlled case series.

BACKGROUND: Being recently released from prison or discharged from hospital, or being dispensed opioids, benzodiazepines, or antipsychotics have been associated with an increased risk of fatal drug overdose. This study aimed to examine the association between these periods and non-fatal drug overdose using a within-person design. METHODS: In this self-controlled case series, we used data from the provincial health insurance client roster to identify a 20% random sample of residents (aged ≥10 years) in British Columbia, Canada between Jan 1, 2015, and Dec 31, 2017 (n=921 346). Individuals aged younger than 10 years as of Jan 1, 2015, or who did not have their sex recorded in the client roster were excluded. We used linked provincial health and correctional records to identify a cohort of individuals who had a non-fatal overdose resulting in medical care during this time period, and key exposures, including periods of incarceration, admission to hospital, emergency department care, and supply of medications for opioid use disorder (MOUD), opioids for pain (unrelated to MOUD), benzodiazepines, and antipsychotics. Using a self-controlled case series, we examined the association between the time periods during and after each of these exposures and the incidence of non-fatal overdose with case-only, conditional Poisson regression analysis. Sensitivity analyses included recurrent overdoses and pre-exposure risk periods. FINDINGS: We identified 4149 individuals who had a non-fatal overdose in 2015-17. Compared with unexposed periods (ie, all follow-up time that was not part of a designated risk period for each exposure), the incidence of non-fatal overdose was higher on the day of admission to prison (adjusted incidence rate ratio [aIRR] 2·76 [95% CI 1·51-5·04]), at 1-2 weeks (2·92 [2·37-3·61]), and 3-4 weeks (1·34 [1·01-1·78]) after release from prison, 1-2 weeks after discharge from hospital (1·35 [1·11-1·63]), when being dispensed opioids for pain (after ≥4 weeks) or benzodiazepines (entire use period), and from 3 weeks after discontinuing antipsychotics. The incidence of non-fatal overdose was reduced during use of MOUD (aIRRs ranging from 0·33 [0·26-0·42] to 0·41 [0·25-0·67]) and when in prison (0·12 [0·08-0·19]). INTERPRETATION: Expanding access to and increasing support for stable and long-term medication for the management of opioid use disorder, improving continuity of care when transitioning between service systems, and ensuring safe prescribing and medication monitoring processes for medications that reduce respiratory function (eg, benzodiazepines) could decrease the incidence of non-fatal overdose.

Comparing mortality and healthcare utilization in the year following a paramedic-attended non-fatal overdose among people who were and were not transported to hospital: A prospective cohort study using linked administrative health data.

BACKGROUND: As the overdose emergency continues in British Columbia (BC), paramedic-attended overdoses are increasing, as is the proportion of people not transported to hospital following an overdose. This study investigated risk of death and subsequent healthcare utilization for people who were and were not transported to hospital after a paramedic-attended non-fatal overdose. METHODS: Using a linked administrative health data set which includes all overdoses that come into contact with health services in BC, we conducted a prospective cohort study of people who experienced a paramedic-attended non-fatal overdose between 2015 and 2016. People were followed for 365 days after the index event. The primary outcomes assessed were all-cause mortality and overdose-related death. Additionally, we examined healthcare utilization after the index event. RESULTS: In this study, 8659 (84%) people were transported and 1644 (16%) were not transported to hospital at the index overdose event. There were 279 overdose deaths (2.7% of people, 59.4% of deaths) during follow-up. There was no significant difference in risk of overdose-related death, though people not transported had higher odds of a subsequent non-fatal overdose event captured in emergency department and outpatient records within 90 days. People transported to hospital had higher odds of using hospital and outpatient services for any reason within 365 days. CONCLUSIONS: Transport to hospital after a non-fatal overdose is an opportunity to provide care for underlying and chronic conditions. There is a need to better understand factors that contribute to non-transport, particularly among people aged 20-59 and people without chronic conditions.

Risk of overdose-related death for people with a history of incarceration.

BACKGROUND AND AIMS: Reported associations between previous incarceration and the risk of overdose-related death are substantially heterogeneous, and previous studies are limited by an inability to control for confounding factors in risk assessment. This study investigated the associations of overdose-related death with previous incarceration and the number or cumulative duration of previous incarcerations, and individual or neighborhood characteristics that may potentially modify the associations. DESIGN AND SETTING: A cohort study using a 20% random sample of residents in British Columbia, Canada. PARTICIPANTS: A total of 765 690 people aged 23 years or older at baseline as of 1 January 2015. Mean age was 50 years; 49% were males. MEASUREMENTS: Previous incarcerations that occurred during the 5-year exposure period (January 2010 to December 2014) were identified using provincial incarceration records. Overdose-related deaths that occurred during the 3-year follow-up period (January 2015 to December 2017) were identified using linked administrative health data. Baseline individual and neighborhood characteristics were retrieved from the provincial health insurance data. FINDINGS: In the cohort, 5743 people had an incarceration history during the exposure period, and 634 people died from drug overdose during the follow-up period. The mortality rate was 897 and 22 per 100 000 person-years for people who did and did not have an incarceration history, respectively. After adjusting for baseline individual and neighborhood characteristics (without any interaction term), people who had an incarceration history were 4.04 times (95% confidence interval 3.23-5.06) more likely to die from drug overdose compared with people without an incarceration history. The association was stronger for females, people without diagnoses of substance use disorder and people without dispensation of opioids for pain or benzodiazepines (P < 0.001 for each interaction term). There was no discernible linear trend between the number or cumulative duration of previous incarcerations and the risk of overdose-related death. CONCLUSIONS: Previous incarceration appears to be a major risk factor for overdose-related death.

Estimates of opioid use disorder prevalence from a regression-based multi-sample stratified capture-recapture analysis.

BACKGROUND: An epidemic of opioid overdose has spread across North America, with illicit drug-related overdose emerging as a leading cause of death in recent years. Estimates of opioid use disorder (OUD) prevalence at the level of the public health service delivery area are needed to project resource needs and identify priority areas for targeted intervention. Our objective is to estimate the annual prevalence of OUD in British Columbia (BC), Canada, from 2000 to 2017. METHODS: We performed a multi-sample stratified capture-recapture analysis to estimate OUD prevalence in BC. The analysis included individuals identified from 3 administrative databases for 2000-2011 and 4 databases for 2012-2017, linked at the individual level. Negative binomial regression models on the counts of individuals within these strata were used to estimate prevalence, adjusting for dependency between databases. RESULTS: OUD prevalence in BC among people aged 12 years or older was 1.00 % (N = 34,663 individuals) in 2000 and increased to 1.54 % (N = 61,080) in 2011. Between 2013 and 2017 prevalence increased from 1.57 % (95 % confidence interval: 1.56-1.58) to 1.92 % (1.89-1.95; N = 83,760; 82,492-84,855). The greatest increases in prevalence were observed among males 12-30 years old and 31-44 years old, with 43.2 % and 40.2 % increases from 2013 to 2017. CONCLUSIONS: In BC, the OUD prevalence was 1.92 % among people 12 years or older in 2017. We estimated that prevalence has nearly doubled since 2000, with the highest increases in prevalence observed among males under 45.

Alcohol distribution reforms and school proximity to liquor sales outlets in New Brunswick.

OBJECTIVES: The purpose of this project was to evaluate how changes to the sale of alcohol in New Brunswick would be distributed across urban and rural communities, and low- and high-income neighbourhoods. The study objectives were to 1) estimate the population living close to alcohol outlets before and after liquor distribution reforms, 2) identify communities or regions that would be more or less affected, and 3) determine whether expanding access to alcohol products would reduce school proximity to retailers. METHODS: Data from Statistics Canada, Desktop Mapping Technologies Inc. (DMTI), and geocoded publicly available information were spatially linked and analyzed using descriptive statistics. The populations living within 499 m, 500-999 m and 1-5 km of an outlet were estimated, and the distances from schools to stores were examined by geographic characteristics and neighbourhood socio-economic status. RESULTS: Permitting the sale of alcohol in all grocery stores throughout the province would increase the number of liquor outlets from 153 to 282 and would increase the population residing within 499 m of an outlet by 97.49%, from 19 886 to 39 273 residents. The sale of alcohol in grocery stores would result in an additional 35 liquor sales outlets being located within 499 m of schools. Low-income neighbourhoods would have the highest number and proportion of stores within 499 m of schools. CONCLUSION: The findings of this study demonstrate the importance of considering social, economic and health inequities in the context of alcohol policy reforms that will disproportionately affect low-income neighbourhoods and youth living within these areas.

The emotional health and well-being of Canadians who care for persons with mental health or addictions problems.

The purpose of this project was to examine the emotional health and well-being of Canadian caregivers of persons with significant mental health or addictions problems. We assessed the emotional health of caregivers by care-receiver condition type (i.e. mental health or addictions vs. physical or other health problems), levels of caregiver stress and methods particularly for reducing stress among caregivers of persons with mental health or addictions disorders. Weighted cross-sectional data from the 2012 General Social Survey (Caregiving and Care Receiving) were modelled using weighted descriptive and logistic regression analyses to examine levels of stress and the emotional health and well-being of caregivers by care-receiver condition type. Caregivers of persons with mental health or addictions problems were more likely to report that caregiving was very stressful and that they felt depressed, tired, worried or anxious, overwhelmed; lonely or isolated; short-tempered or irritable; and resentful because of their caregiving responsibilities. The results of this study suggest that mental health and addictions caregivers may experience disparate stressors and require varying services and supports relative to caregivers of persons with physical or other health conditions.
