Perceived unmet need and barriers to care amongst street-involved people who use illicit drugs

Profiles of Permanent Supportive Housing Residents Related to Their Housing Conditions, Service Use, and Associated Sociodemographic and Clinical Characteristics

As permanent supportive housing (PSH) is the main strategy promoted to reduce homelessness, understanding how PSH resident profiles may be differentiated is crucial to the optimization of PSH implementation - and a subject that hasn't been studied yet. This study identified PSH resident profiles based on their housing conditions and service use, associated with their sociodemographic and clinical characteristics. In 2020-2021, 308 PSH residents from Quebec (Canada) were interviewed, with K-means cluster analysis produced to identify profiles and subsequent analyses to compare profiles and PSH resident characteristics. Of the three profiles identified, Profiles 1 and 2 (70% of sample) showed moderate or poor housing, neighborhood, and health conditions, and moderate or high unmet care needs and service use. Besides their "moderate" conditions, Profile 1 residents (52%) reported being in PSH for more than two years and being less educated. With the "worst" conditions and high service use, Profile 2 (18%) included younger individuals, while Profile 3 (30%) showed the "best" conditions and integrated individuals with more protective determinants (e.g., few in foster care, homelessness at older age, more self-esteem), with a majority living in single-site PSH and reporting higher satisfaction with support and community-based services. Profiles 1 and 2 may be provided with more psychosocial, crisis, harm reduction, and empowerment interventions, and peer helper support. Profile 2 may benefit from more intensive and integrated care, and better housing conditions. Continuous PSH may be sustained for Profile 3, with regular monitoring of service satisfaction and met needs.

Perceived Higher Unmet Care Needs among Adults in Permanent Supportive Housing

This study is original in that it assesses various types of care needs, barriers to care, and factors associated with higher unmet needs among 308 permanent supportive housing (PSH) residents in Quebec (Canada). Data from structured interviews that featured the Perceived Need for Care Questionnaire were collected from 2020 to 2022, controlling for the COVID-19 pandemic period. Eight types of care (e.g., information, counseling) were accounted for. Based on the Behavioral Model for Vulnerable Populations, predisposing, need, and enabling factors associated with higher unmet care needs were assessed using a negative binomial regression model. The study found that 56% of adult PSH residents, even those who had lived in PSH for 5 + years, had unmet care needs. Twice as many unmet needs were due to structural (e.g., care access) rather than motivational barriers. Living in single-site PSH, in healthier neighborhoods, having better quality of life and self-esteem, and being more satisfied with housing and outpatient care were associated with fewer unmet care needs. PSH residents with co-occurring mental disorders (MD) and substance use disorders (SUD), and with moderate or severe psychological distress were likely to have more unmet needs. Better access to care, counseling and integrated treatment for co-occurring MD-SUD might be improved, as well as access to information on user rights, health and available support. Welfare benefits could be increased, with more peer support and meaningful activities, especially in single-site PSH. The quality of the neighborhoods where PSH are located might also be better monitored.

Characterizing the Use of Healthcare Access Supports Among People Who Use Drugs in Vancouver, Canada, 2017 to 2020: A Cohort Study

BACKGROUND

For structurally marginalized populations, including people who use drugs (PWUD), equitable access to healthcare can be achieved through healthcare access supports. However, few studies characterized utilization of formal (eg, outreach workers, healthcare professionals) and informal (eg, friends/family) supports. Therefore, we sought to estimate the prevalence of and factors associated with receiving each type of support among PWUD.

METHODS

We used data from 2 prospective cohort studies of PWUD in Vancouver, Canada, in 2017 to 2020. We constructed separate multivariable generalized linear mixed-effects models to identify factors associated with receiving each of the 3 types of supports (ie, healthcare professionals, outreach workers/peer navigators, and informal supports) compared to no supports.

RESULTS

Of 996 participants, 350 (35.1%) reported receiving supports in the past 6 months at baseline, through informal supports (6.2%), outreach workers (14.1%), and healthcare professionals (20.9%). In multivariable analyses, HIV positivity, chronic pain, and avoiding healthcare due to the past mistreatment were positively associated with receiving supports from each of healthcare professionals and outreach workers. Men were less likely to receive any types of the supports (all P < .05).

CONCLUSIONS

Utilization of healthcare access supports was relatively low in this sample. However, formal supports appeared to have reached PWUD exhibiting more comorbidities and experiencing discrimination in healthcare. Further efforts to make formal supports more available would benefit PWUD with unmet healthcare needs, particularly men.

Providers' Experiences and Perspectives in Treating Patients With Co-Occurring Opioid and Stimulant Use Disorders in the Hospital

BACKGROUND

The overdose crisis is increasingly characterized by opioid and stimulant co-use. Despite effective pharmacologic treatment for both opioid use disorder (OUD) and contingency management for stimulant use disorders, most individuals with these co-occurring conditions are not engaged in treatment. Hospitalization is an important opportunity to engage patients and initiate treatment, however existing hospital addiction care is not tailored for patients with co-use and may not meet the needs of this population.

METHODS

Semi-structured interviews were conducted with hospital providers about their experiences and perspectives treating patients with opioid and stimulant co-use. We used directed content analysis to identify common experiences and opportunities to improve hospital-based treatment for patients with co-use.

RESULTS

From qualitative interviews with 20 providers, we identified 4 themes describing how co-use complicated hospital-based substance use treatment: (1) patients' unstable circumstances impacting the treatment plan, (2) co-occurring withdrawals are difficult to identify and treat, (3) providers holding more stigmatizing views of patients with co-use, and (4) stimulant use is often "ignored" in the treatment plans. Participants also described a range of potential opportunities to improve hospital-based treatment of co-use that fall into 3 categories: (1) provider practice changes, (2) healthcare system changes, and (3) development and validation of clinical tools and treatment approaches.

CONCLUSIONS

We identified unique challenges providing hospital addiction medicine care to patients who use both opioids and stimulants. These findings inform the development, implementation, and testing of hospital-based interventions for patients with co-use.

Barriers to and facilitators of screening for cervical and breast cancer: Experiences of non-adherent women with current or previous drug use

Objective

Women with current or previous drug use (WCPDU) have an increased risk of poor cervical and breast cancer outcomes, and low participation in screening for these cancer forms. The aim of this study was to assess self-reported barriers to and facilitators of cervical and breast cancer screening, among WCPDU.

Methods

A survey based on results from a previous qualitative study about WCPDUs experiences of cancer screening was distributed to WCPDU at six opioid agonist treatment (OAT) clinics and one needle exchange program (NEP) in Malmö, Sweden, and through the Drug Users Union in Stockholm, Sweden. Data on barriers to and facilitators of cancer screening reported by 222 non-adherent WCPDU was analyzed by descriptive statistics. The barriers were structured according to an established model of healthcare access.

Results

The most frequently reported barriers to cervical as well as breast cancer screening were non-receipt of screening invitations (36 % and 25 %, respectively), trouble remembering the appointment (27 % and 30 %) and other priorities (26 % and 29 %). Common suggested facilitators for both cervical and breast cancer screening were screening access at, e.g., a NEP or OAT clinic (45 % and 40 %) and practical support to attend the screening appointment (40 % and 38 %).

Conclusions

In contrast to general population women, WCPDU report mainly practical barriers to cervical and breast cancer screening. However, NEP participants frequently reported experience of stigma and poor reception as barriers to screening. Interventions to minimize barriers to screening are crucial to decrease the increased cancer morbidity and mortality among WCPDU.

Profiles of Emergency Department Users with Psychiatric Disorders Related to Barriers to Outpatient Care

Emergency department (ED) overcrowding is a growing problem worldwide. High ED users have been historically targeted to reduce ED overcrowding and associated high costs. Patients with psychiatric disorders, including substance-related disorders (SRDs), are among the largest contributors to high ED use. Since EDs are meant for urgent cases, they are not an appropriate setting for treating recurrent patients or replacing outpatient care. Identifying ED user profiles in terms of perceived barriers to care, service use, and sociodemographic and clinical characteristics is crucial to reduce ED use and unmet needs. Data were extracted from medical records and a survey was conducted among 299 ED patients from 2021 to 2022 in large Quebec networks. Cluster algorithms and comparison tests identified three profiles. Profile 1 had the most patients without barriers to care, with case managers, and received the best primary care. Profile 2 reported moderate barriers to care and low primary care use, best quality of life, and more serious psychiatric disorders. Profile 3 had the most barriers to care, high ED users, and lower service satisfaction and perceived mental/health conditions. Our findings and recommendations inform decision-makers on evidence-based strategies to address the unmet needs of these vulnerable populations.

Variables Associated with Quality of Life Among Individuals Living in Permanent Supportive Housing

This study identified individual sociodemographic and clinical characteristics and service use patterns associated with quality of life (QoL) among 308 individuals living in permanent supportive housing (PSH) in Québec (Canada). Data were collected between 2020 and 2022, and linear multivariate analyses produced. Results demonstrated that better individual psychosocial conditions were positively associated with higher QoL. As well, living in PSH located in good neighborhoods for at least 5 years, higher self-esteem and community integration were positively associated with greater QoL. Met needs, satisfaction with housing support services, and no use of acute care were also linked with positive QoL. Comprehensive efforts to improve treatment for mental health disabilities responsive to the needs of PSH residents, and sustained long-term housing may reinforce QoL. Encouraging active participation in community-based activities, incorporating biophilic design into the neighborhoods around PSH, and promoting satisfaction with care may also enhance QoL.

Screening for breast and cervical cancer among OST patients: a qualitative study of barriers and suggested interventions to increase participation

PURPOSE

Women with current or previous drug use are at risk of poor breast and cervical cancer outcomes. While screening is known to decrease cancer mortality, screening participation is sparsely investigated among drug dependent women. The aim of this study was to explore experiences of breast and cervical cancer screening-including barriers and suggested interventions to promote increased participation-among women in opioid substitution treatment (OST).

METHODS

Three focus group interviews were conducted at one OST clinic in Malmö, Sweden. The interviews were moderated by OST staff, assisted by a researcher. A descriptive qualitative analysis was carried out using a template analysis approach, employing a model of healthcare access to organize the description of barriers.

RESULTS

The 11 participants reported several barriers to screening access, affecting the perceived need of screening and the opportunities to seek and reach screening services. Some barriers appear to be specific to women with previous or current drug use. Suggested interventions were moral and practical support, integrated/specialized delivery of screening services, and enhanced screening invitation procedures.

CONCLUSIONS

The study findings provide insight to difficulties with screening compliance among women with current or previous drug use, and provide a knowledge base for quantitative and intervention studies.

Treatment setting among individuals with opioid use and criminal legal involvement, housing instability, or Medicaid insurance, 2015-2021

Background

Individuals with criminal legal involvement (CLI), housing instability, or Medicaid insurance may experience barriers accessing substance use treatment in certain settings. Previous research has found individuals in these groups are less likely to receive medications for opioid use disorder (MOUD), but the role treatment setting may play in low rates of MOUD is unclear.

Methods

We conducted a cross-sectional study using nationally representative survey data from 2015 to 2021. We estimated the proportion of individuals who had CLI, housing instability, or Medicaid insurance who received substance use treatment in a variety of settings. We used multivariable logistic regressions to estimate the associations between group and the receipt of MOUD across treatment settings.

Results

Individuals with CLI, housing instability, or Medicaid insurance were more likely to receive substance use treatment in hospitals, rehabilitation, and mental health facilities compared with individuals not in these groups. However, all groups accessed substance use treatment in doctors' offices at similar rates. Treatment at a doctor's office was associated with the highest likelihood of receiving MOUD (aOR 4.73 [95% CI: 2.2.15-10.43]). Across multiple treatment settings, Individuals with CLI or housing instability were less likely to receive MOUD.

Conclusions

Individuals with CLI, housing instability, or Medicaid insurance are more likely to access substance use treatment at locations associated with lower rates of MOUD use. MOUD access across treatment settings is needed to improve engagement and retention in treatment for patients experiencing structural disadvantage or who have low incomes.

Perceived need for care and stigma experiences among individuals with methamphetamine-related admissions to inpatient mental health wards

BACKGROUND

There are gaps in our understanding of treatment needs among people who use methamphetamine. We examined the demographics, perceived treatment needs, barriers to accessing care, and stigma experienced by an inpatient sample of people who use methamphetamine.

METHODS

This study surveyed a convenience sample of patients admitted to psychiatry wards with a history of methamphetamine use in Winnipeg, Canada, between May 1 and July 31, 2019. The Perceived Need for Care Questionnaire (PNCQ-9) was used to assess treatment needs and barriers to care, and the Substance Use Stigma Mechanisms Scale (SU-SMS) was used to assess enacted, anticipated, and internalized stigma. Prevalence rates of perceived need, stigma, and demographic variables were determined.

RESULTS

A total of 103 potential participants were identified, with 34 completing the survey. The most common age group was 21-30 years of age (41.2%); an approximate equal number of men and women; and almost all were single and never married (91.1%). Rates of perceived need for care were very high across all treatment types, including 91% identifying a need for medication treatment for their mental health or substance use. Despite the majority receiving care across the seven types of care described in the PNCQ-9, most felt they did not receive enough care. Unmet need for care was therefore high in many categories, including rates of 87% for counselling and skills training. The most common barriers to having needs met were a desire to self-manage substance use, and not receiving care after asking for help. Almost all participants reported experiencing stigma (94%). Stigma from family was endorsed significantly more than stigma from health care providers (p = 0.005).

CONCLUSIONS

The average hospitalized person who uses methamphetamine in this sample is young, single, and has not completed any post-secondary education. High rates of perceived treatment need suggest an awareness of problems with methamphetamine, yet most interventions are perceived as inadequate. People who used methamphetamine felt highly stigmatized, particularly by their family members. Trial registration Registered with the Health Research Ethics Board at the University of Manitoba (Number HS22605 (H2019:072), renewed February 14, 2022).

Making community pharmacies psychologically informed environments (PIE): a feasibility study to improve engagement with people using drug services in Scotland

AIM

This developmental study tested the feasibility of training pharmacy staff on the psychologically informed environments (PIE) approach to improve the delivery of care.

BACKGROUND

Community pharmacies provide key services to people who use drugs (PWUD) through needle exchange services, medication-assisted treatment and naloxone distribution. PWUD often have trauma backgrounds, and an approach that has been demonstrated to work well in the homeless sector is PIEs.

METHODS

Bespoke training was provided by clinical psychologists and assessed by questionnaire. Staff interviews explored changes made following PIE training to adapt the delivery of care. Changes in attitude of staff following training were assessed by questionnaire. Peer researchers interviewed patient/client on observed changes and experiences in participating pharmacies. Staff interviews were conducted six months after training to determine what changes, if any, staff had implemented. Normalisation process theory (NPT) provided a framework for assessing change.

FINDINGS

Three pharmacies (16 staff) participated. Training evaluation was positive; all participants rated training structure and delivery as 'very good' or 'excellent'. There was no statistically significant change in attitudes. COVID-19 lockdowns restricted follow-up data collection. Staff interviews revealed training had encouraged staff to reflect on their practice and communication and consider potentially discriminatory practice. PIE informed communication skills were applied to manage COVID-19 changes. Staff across pharmacies noted mental health challenges for patients. Five patients were interviewed but COVID-19 delays in data collection meant changes in delivery of care were difficult to recall. However, they did reflect on interactions with pharmacy staff generally. Across staff and patient interviews, there was possible conflation of practice changes due to COVID-19 and the training. However, the study found that training pharmacy teams in PIE was feasible, well received, and further development is recommended. There was evidence of the four NPT domains to support change (coherence, cognitive participation, collective action and reflexive monitoring).

Mental health symptoms among homeless shelter residents during COVID-19 lockdown in Tshwane, South Africa

BACKGROUND

In order to contain the spread of COVID-19 in South Africa during the national state of emergency, the Gauteng Department of Social Development established temporary shelters and activated existing facilities to provide basic needs to street-homeless people in Tshwane, which facilitated primary health care service-delivery to this community.

AIM

This study aimed to determine and analyse the prevalence of mental health symptoms and demographic characteristics among street-homeless people living in Tshwane's shelters during lockdown.

SETTING

Homeless shelters set up in Tshwane during level 5 of the COVID-19 lockdown in South Africa.

METHODS

A cross-sectional, analytical study was conducted using a Diagnostic and Statistical Manual of Mental Disorders (DSM-5)-based questionnaire that looked at 13 mental health symptom domains.

RESULTS

Presence of moderate-to-severe symptoms were reported among the 295 participants as follows: substance use 202 (68%), anxiety 156 (53%), personality functioning 132 (44%), depression 85 (29%), sleep problems 77 (26%), somatic symptoms 69 (23%), anger 62 (21%), repetitive thoughts and behaviours 60 (20%), dissociation 55 (19%), mania 54 (18%), suicidal ideation 36 (12%), memory 33 (11%) and psychosis 23 (8%).

CONCLUSION

A high burden of mental health symptoms was identified. Community-oriented and person-centred health services with clear care-coordination pathways are required to understand and overcome the barriers street-homeless people face in accessing health and social services.Contribution: This study determined the prevalence of mental health symptoms within the street-based population in Tshwane, which has not previously been studied.

Participation in screening for breast and cervical cancer among women with current or previous drug use: a survey study

BACKGROUND

Women with current or previous drug use (WCPDU) have an increased risk of poor breast and cervical cancer outcomes. Screening is known to decrease the mortality of these common cancer forms, but screening participation has been sparsely investigated among women with drug dependency. The aim of this study was to assess participation in screening for breast and cervical cancer among WCPDU.

METHODS

We recruited WCPDU to a survey study, from six opioid substitution treatment (OST) clinics and one needle exchange program (NEP) in Malmö, Sweden, and through the Drug Users Union in Stockholm, Sweden. The survey was constructed according to results from focus group discussions about cancer screening in a sample of women in OST. Survey data were analyzed using descriptive statistics. We analyzed associations between non-compliance to screening and healthcare contact (OST, NEP or none) by logistic regression analysis; unadjusted and adjusted for age, native language, housing situation, educational attainment and main source of income.

RESULTS

A total of 298 women (median age 43 years) responded to the survey. The self-reported compliance with cancer screening recommendations was 29% for breast cancer screening and 41% for cervical cancer screening. Non-compliance with cervical cancer screening was associated with NEP participation in univariate but not multivariate analysis. We did not find an association between non-compliance with breast cancer screening and healthcare contact. Non-compliance with screening for cervical cancer was also associated with unstable housing in univariate and multivariate analyses, and inversely associated with increasing age in a univariate analysis. Non-compliance with breast cancer was associated with unstable housing in a univariate analysis, and inversely associated with not having Swedish as a native language in a multivariate analysis.

CONCLUSION

The self-reported compliance with the national cancer screening programs for breast cancer and cervical cancer of WCPDU is notably lower than in the Swedish general population. Women with unstable housing seem to be particularly vulnerable to non-compliance with cancer screening. Interventions to minimize barriers to cancer screening are crucial to decrease the increased cancer morbidity and mortality among WCPDU.

Impact of an addiction medicine consult team intervention in a Canadian inner city hospital on acute care utilization: a pragmatic quasi-experimental study

Background

Inner city patients have a higher illness burden and need for care, but experience more unmet care needs. Hospital Addiction Medicine Consult Teams (AMCTs) are a promising emerging intervention. The objective of this study was to assess the impact of a Canadian AMCT-like intervention for inner city patients on reduction in high emergency department (ED) use, hospital admission, and inpatient length of stay.

Methods

Using a community-engaged, two-arm, pre-post, longitudinal quasi-experimental study design, 572 patients reporting active substance use, unstable housing, unstable income, or a combination thereof (302 at intervention site, 270 at control sites) were enrolled. Survey and administrative health service data were collected at baseline, six months post-enrolment, and 12 months post-enrolment. Multivariable regression models tested the intervention effect, adjusting for clinically important covariables (inpatient status at enrolment, medical complexity, age, gender, Indigenous identity, shelter use, opioid use).

Results

Initial bivariable analyses demonstrated an intervention effect on reduction in admissions and length of stay, however, this effect was no longer significant after adjusting for covariables. There was no evidence of reduction in high ED use on either bivariable or subsequent multivariable analysis.

Conclusions

After adjusting for covariables, no AMCT intervention effect was detected for reduction in high ED use, inpatient admission, or hospital length of stay. Further research is recommended to assess other patient-oriented intervention outcomes.

Violence, policing, and systemic racism as structural barriers to substance use treatment amongst women sex workers who use drugs: Findings of a community-based cohort in Vancouver, Canada (2010-2019)

BACKGROUND

Despite a high prevalence of substance use among women sex workers (SWs), rigorous social epidemiologic data on substance use treatment experiences among SWs remains limited. Given these gaps and the disproportionate burden of criminalization borne by Indigenous SWs, we evaluated (1) structural correlates of unsuccessful attempts to access substance use treatment; and (2) the interaction between policing and Indigenous ancestry on unsuccessful attempts to access treatment among SWs who use drugs.

METHODS

Prospective data were from an open community-based cohort of women SWs (2010-2019) in Vancouver, Canada. Bivariate and multivariable logistic regression with generalized estimating equations(GEE) assessed correlates of unsuccessful attempts to access treatment. A multivariable GEE confounder model examined the interaction between Indigenous ancestry and policing on unsuccessful attempts to access treatment.

RESULTS

Amongst 645 SWs who used drugs, 32.1 % reported unsuccessful attempts to access substance use treatment during the 9.5-year study. In multivariable GEE analysis, unsuccessful substance use treatment access was associated with identifying as a sexual/gender minority (AOR: 1.90, 95 %CI:1.37-2.63), opioid use (AOR: 1.43, 95 %CI: 1.07-1.91), and exposure to homelessness (AOR: 1.72; 95 %CI:1.33-2.21), police harassment (AOR: 1.48, 95 %CI:1.03-2.13), workplace violence (AOR: 1.80, 95 %CI: 1.31-2.49) and intimate partner violence (AOR: 2.11, 95 %CI:1.50-2.97). In interaction analysis, Indigenous SWs who experienced police harassment faced the highest odds of unsuccessful attempts to access substance use treatment (AOR: 2.59, 95 %CI:1.65-4.05).

CONCLUSION

Findings suggest a need to scale-up culturally-safe, trauma-informed addictions, gender-based violence, and sex worker services, alongside dismantling of systemic racism across and beyond health and addictions services.

Predictors of Frequent Emergency Department Use and Hospitalization among Patients with Substance-Related Disorders Recruited in Addiction Treatment Centers

Few studies have assessed the overall impact of outpatient service use on acute care use, comparing patients with different types of substance-related disorders (SRD) and multimorbidity. This study aimed to identify sociodemographic and clinical characteristics and outpatient service use that predicted both frequent ED use (3+ visits/year) and hospitalization among patients with SRD. Data emanated from 14 Quebec (Canada) addiction treatment centers. Quebec administrative health databases were analyzed for a cohort of 17,819 patients over a 7-year period. Multivariable logistic regression models were produced. Patients with polysubstance-related disorders, co-occurring SRD-mental disorders, severe chronic physical illnesses, and suicidal behaviors were at highest risk of both frequent ED use and hospitalization. Having a history of homelessness, residing in rural areas, and using more outpatient services also increased the risk of acute care use, whereas high continuity of physician care protected against acute care use. Serious health problems were the main predictor for increased risk of both frequent ED use and hospitalization among patients with SRD, whereas high continuity of care was a protective factor. Improved quality of care, motivational, outreach and crisis interventions, and more integrated and collaborative care are suggested for reducing acute care use.

Trends and age-related characteristics of substance use in the hospitalized homeless population

We aimed to examine trends and characteristics of substance use (opioid, cocaine, marijuana, and heroin) among hospitalized homeless patients in comparison with other hospitalized patients in 3 states.This was a cross-sectional study, based on the 2007 to 2015 State Inpatient Data of Arizona, Florida, and Washington (n = 32,162,939). Use of opioid, cocaine, marijuana, heroin, respectively, was identified by the International Classification of Diseases, 9th Revision. Multi-level multivariable regressions were performed to estimate relative risk (RR) and 95% confidence intervals (CI). Dependent variables were the use of substances (opioid, cocaine, marijuana, and heroin), respectively. The main independent variable was homeless status. The subgroup analysis by age group was also conducted.Homeless patients were associated with more use of opioid (RR [CI]), 1.23 [1.20-1.26], cocaine 2.55 [2.50-2.60], marijuana 1.43 [1.40-1.46], and heroin 1.57 [1.29-1.91] compared to other hospitalized patients. All hospitalized patients including those who were homeless increased substance use except the use of cocaine (RR [CI]), 0.57 [0.55-0.58] for other patients and 0.60 [0.50-0.74] for homeless patients. In all age subgroups, homeless patients 60 years old or older were more likely to be hospitalized with all 4 types of substance use, especially, cocaine (RR [CI]), 6.33 [5.81-6.90] and heroin 5.86 [2.08-16.52] in comparison with other hospitalized patients.Homeless status is associated with high risks of substance use among hospitalized patients. Homeless elderly are particularly vulnerable to use of hard drugs including cocaine and heroin during the opioid epidemics.

Street Clinics and the Healthcare of Vulnerable Homeless Communities in Brazil: A Qualitative Study

(1) Background: homeless people are characterized by serious social vulnerability and difficulty in accessing health services worldwide. In Brazil, this population is supported by the Street Clinic teams who are challenged to establish intersectoral networks to expand access and promote unique and humanized care from the perspective of harm reduction. The study aimed to analyze the practices of professionals working at the Street Clinic in a city in the interior of São Paulo, Brazil, to tackle the vulnerabilities of the homeless population and expand access to the health care network. (2) Methods: a qualitative study was conducted with a social approach in which we interviewed eight workers from the Street Clinic. Data were analyzed using the thematic content analysis tool. (3) Results: three nuclei of meaning were built: stigma and prejudice as the main barriers to accessing services, harm reduction as a humanized care practice and valuing autonomy, and Street Clinic as a gateway to the health system and main interlocutor with other services. (4) Conclusions: the articulation with network services is marked by contradictory relationships, of conflict and trust, signaling the need for greater investment in educational qualifications and working conditions for professionals at all levels of care to expand access to health care.

Unmet service needs and barriers to care of individuals experiencing absolute homelessness in Edmonton, Canada: a cross-sectional survey

PURPOSE

Individuals experiencing absolute homelessness have complex needs but limited access to services, contributing to high rates of morbidity and mortality. The aim of this article is to describe the perceived unmet service needs of individuals experiencing absolute homelessness, identify their barriers to care, and examine factors associated with specific unmet service needs.

METHODS

Using a cross-sectional survey, 150 individuals experiencing absolute homelessness were recruited from Edmonton's inner city and adjoining areas. The majority of participants were male (71.3%) and self-identified as Indigenous (74.0%). An adapted version of the Perceived Need for Care Questionnaire was used to measure past-year unmet needs for 4 types of services: hospital care, counselling, skills training, and harm reduction. Descriptive statistics and bivariate analyses were used; odds ratio and confidence intervals were calculated for statistically significant outcomes.

RESULTS

Overall, 89.3% of participants perceived a need for care for one or more general health and social services during the past year regarding their substance use and/or mental health problems; participants reported the highest levels of unmet need for counselling (42.9%) and skills training (39.2%). Though 73.3% of participants reported receiving any service, only 8.0% of participants reported having their perceived needs fully met.

CONCLUSION

In this study, individuals reported a high percentage of unmet needs. By interacting and engaging with these hard-to-reach individuals, healthcare systems will be more equipped to service them and address their barriers to care. Better patient-centred care, housing and supports for this neglected and underserved population is needed.

A longitudinal cross-sectional analysis of substance use treatment trends for individuals experiencing homelessness, criminal justice involvement, both, or neither - United States, 2006-2018

Background

Individuals experiencing homelessness or criminal justice involvement (CJI) have higher rates of substance use than the general public. Despite documented barriers to accessing treatment, few studies have compared substance use treatment patterns between these groups.

Methods

This paper uses data from the Treatment Episode Dataset-Admissions between 2006 to 2018 to describe characteristics and trends in substance use treatment admissions indicating homelessness (n=2,524,413), CJI (4,764,750), both (509,902), or neither (8,950,797) in the United States. We used multivariable logistic regression to examine trends independent of demographic differences between groups.

Findings

Between 2006 and 2018, the proportion of treatment admissions related to heroin increased across all groups. Methamphetamine-related admissions rose substantially for individuals experiencing homelessness, CJI, or both. By 2018, 27·8% (95% CI: 27·4-28·2%) of admissions for individuals experiencing both were methamphetamine-related and 16·7% (95% CI: 16·3-17·0%) were heroin-related. Conversely, among individuals experiencing neither, 7·5% (95% CI: 7·4-7·5%) of admissions were methamphetamine-related and 33·6% (95% CI: 33·4-33·7%) were heroin-related. Individuals experiencing both homelessness and CJI received lower rates of medications for opioid use disorder (OUD) (8·3%; 95% CI: 8·2-8·3%) compared to individuals experiencing neither (36·4%; 95% CI: 36·4-36·4%).

Interpretation

Community treatment facilities should be supported to provide medications for OUD and accommodate rising rates of methamphetamine and polysubstance-related treatment admissions in populations experiencing complex social drivers of health such as homelessness, CJI, or both.

Inability to contact opioid agonist therapy prescribers during the COVID-19 pandemic in a Canadian setting: a cross-sectional analysis among people on opioid agonist therapy

BACKGROUND

The COVID-19 pandemic and consequent public health response may have undermined key responses to the protracted drug poisoning crisis, including reduced access to opioid agonist therapy (OAT) among people with opioid use disorder. Our study objectives were to estimate the prevalence of and identify factors associated with inability to contact OAT prescribers when in need among people on OAT in a Canadian setting during the dual public health crises.

METHODS

Survey data were collected from three prospective cohort studies of community-recruited people who use drugs between July and November 2020, in Vancouver, Canada. A multivariable logistic regression analysis was used to identify potential factors associated with inability to contact OAT prescribers among patients who accessed OAT in the past 6 months.

RESULTS

Among 448 respondents who reported accessing OAT in the past 6 months, including 231 (54.9%) men, 85 (19.0%) reported having been unable to contact OAT prescribers when needed, whereas 268 (59.8%) reported being able to talk to their prescriber when needed, and 95 (21.2%) reported that they did not want to talk to their medication prescriber in the previous 6 months. Among those who reported inability to contact prescribers, 45 (53.6%) reported that their overall ability to contact prescribers decreased since the start of the pandemic. In multivariable analyses, factors independently associated with inability to talk to OAT prescribers included: chronic pain (Adjusted Odds Ratio [AOR] = 1.82; 95% Confidence Interval [CI] 1.02, 3.27), moderate to severe symptoms of depression or anxiety (AOR = 4.74; 95% CI 2.30, 9.76), inability to access health/social services (AOR = 2.66; 95% CI 1.41, 5.02), and inability to self-isolate or socially distance most or all of the time (AOR = 2.13; 95% CI 1.10, 4.14).

CONCLUSIONS

Overall, approximately one fifth of the sample reported inability to contact their OAT prescribers when needed, and those people were more likely to have co-occurring vulnerabilities (i.e., co-morbidities, inability to access health/social services) and higher vulnerability to COVID-19. Interventions are needed to ensure optimal access to OAT and mitigate the deepening health inequities resulting from the COVID-19 pandemic and the escalating drug poisoning crisis.

Perceived unmet substance use and mental health care needs of acute care patients who use drugs: A cross-sectional analysis using the Behavioral Model for Vulnerable Populations

INTRODUCTION

The perceived unmet service needs of acute care-seeking people who use illegal drugs (PWUD) have been poorly documented, despite evidence of frequent hospital utilisation. This study applies the Behavioral Model for Vulnerable Populations to investigate correlates of unmet service needs in this subpopulation.

METHODS

Survey data from 285 PWUD at three urban Canadian acute care centres were examined. The survey included the Perceived Need for Care Questionnaire, which measured service seeking and care satisfaction for mental health and substance use concerns across seven types of services, as well as barriers to having care needs met. The Behavioral Model for Vulnerable Populations was applied in hierarchical setwise logistic regression to examine associations between high unmet service need and socio-structural predictors (i.e. predisposing, enabling and need factors).

RESULTS

Almost half (46%) of participants reported a high level of unmet service need, despite seeking services during the past year. Participants reporting recent criminal activity, adverse childhood experiences, transitory sleeping, having no community support worker, and meeting screening criteria for depression were more likely to report a high level of unmet service needs. Structural barriers to care (57%) were more commonly reported than motivational barriers (43%).

DISCUSSION AND CONCLUSIONS

Acute care-seeking PWUD experience high rates of unmet service needs for their mental health and substance use problems. Strategies that can help overcome structural barriers to care are necessary to help address the service needs of this population.

Towards cross-Canada monitoring of the unregulated street drug supply

Background

The well-being of people who use drugs (PWUD) continues to be threatened by substances of unknown type or quantity in the unregulated street drug supply. Current efforts to monitor the drug supply are limited in population reach and comparability. This restricts capacity to identify and develop measures that safeguard the health of PWUD. This study describes the development of a low-barrier system for monitoring the contents of drugs in the unregulated street supply. Early results for pilot sites are presented and compared across regions.

Methods

The drug content monitoring system integrates a low-barrier survey and broad spectrum urine toxicology screening to compare substances expected to be consumed and those actually in the drug supply. The system prototype was developed by harm reduction pilot projects in British Columbia (BC) and Montreal with participation of PWUD. Data were collected from harm reduction supply distribution site clients in BC, Edmonton and Montreal between May 2018–March 2019. Survey and urine toxicology data were linked via anonymous codes and analyzed descriptively by region for trends in self-reported and detected use.

Results

The sample consisted of 878 participants from 40 sites across 3 regions. Reported use of substances, their detection, and concordance between the two varied across regions. Methamphetamine use was reported and detected most frequently in BC (reported: 62.8%; detected: 72.2%) and Edmonton (58.3%; 68.8%). In Montreal, high concordance was also observed between reported (74.5%) and detected (86.5%) cocaine/crack use. Among those with fentanyl detected, the percentage of participants who used fentanyl unintentionally ranged from 36.1% in BC, 78.6% in Edmonton and 90.9% in Montreal.

Conclusions

This study is the first to describe a feasible, scalable monitoring system for the unregulated drug supply that can contrast expected and actual drug use and compare trends across regions. The system used principles of flexibility, capacity-building and community participation in its design. Results are well-suited to meet the needs of PWUD and inform the local harm reduction services they rely on. Further standardization of the survey tool and knowledge mobilization is needed to expand the system to new jurisdictions.

The impact of PSTD on service access among people who use drugs in Vancouver, Canada

BACKGROUND

Settings throughout the United States and Canada are contending with high rates of drug-related overdose. This in turn has prompted efforts to more effectively engage people who use drugs (PWUD) in treatment and care. However, while co-morbid mental disorders are prevalent among PWUD and can undermine access to services, the impact of post-traumatic stress disorder (PTSD) on service access is not known. Therefore, we sought to assess whether PTSD is associated with difficulties accessing health and social services among PWUD in Vancouver, Canada.

METHODS

Survey data was derived from two prospective cohorts of PWUD in Vancouver, Canada for the period of April 2017 to November 2018. PTSD was assessed using the PTSD Checklist for the DSM-V (PCL-5). Generalized estimating equations (GEE) was used to estimate the relationship between PTSD and self-reported inability to access health and social services, after adjustment for confounders.

RESULTS

Among 810 participants included in our analysis, 316 (39.0%) participants qualified for a provisional PSTD diagnosis, and 117 (14.4%) reported difficulties accessing services. In a multivariable GEE analysis, a PTSD diagnosis (adjusted odds ratio = 1.69, 95% confidence interval: 1.12-2.55) was independently associated with difficulties accessing services.

CONCLUSIONS

We found high rates of PTSD and self-reported difficulties accessing services among PWUD in Vancouver, as well as a positive association between PTSD and difficulties with service access. These findings highlight the need for trauma-informed approaches to service delivery for PWUD, as well as enhanced provider training specific to PTSD.

A Portrait of Mental Health Services Utilization and Perceived Barriers to Care in Men and Women Evacuated During the 2016 Fort McMurray Wildfires

This study examines the influence of gender on mental health services utilization and on perceived barriers to treatment one year after the 2016 Fort McMurray wildfires. Data was collected through a phone survey from May to July 2017 (N = 1510). Participants were English-speaking evacuees aged 18 and older. Mental health services utilization and barriers to mental health care were assessed with the Perceived Need for Care questionnaire. Probable diagnoses of posttraumatic stress disorder, depression and insomnia were assessed with validated self-report questionnaires. Multiple logistic regressions confirmed that gender was a significant predictor of services utilization, after controlling for associated sociodemographic variables and presence of probable diagnoses. Women were respectively 1.50, 1.55 and 1.86 times more likely than men to receive information, medication and psychological help. Self-reliance was the most frequently reported reason for not receiving help, and motivational barriers, such as pessimism and stigma, were reported in a higher proportion than structural barriers, including nonresponse and finance. No significant gender differences were found in the types of perceived barriers to services. Among the Fort McMurray fire evacuees, mental health services utilization was similar to other studies on natural disaster victims, and higher in women than in men. Efforts to increase services utilization in natural disaster victims should focus on motivational barriers and offering treatments fostering people's autonomy, such as online treatments.

HIV treatment cascade among people who inject drugs in Ukraine

The HIV treatment cascade is an effective tool to track progress and gaps in the HIV response among key populations. People who inject drugs (PWID) remain the most affected key population in Ukraine with HIV prevalence of 22% in 2015. We performed secondary analysis of the 2017 Integrated Bio-Behavioral Surveillance (IBBS) survey data to construct the HIV treatment cascade for PWID and identify correlates of each indicator achievement. The biggest gap in the cascade was found in the first "90", HIV status awareness: only 58% [95% CI: 56%-61%] of HIV-positive PWID reported being aware of their HIV-positive status. Almost 70% [67%-72%] of all HIV-infected PWID who were aware of their status reported that they currently received antiretroviral therapy (ART). Almost three quarters (74% [71%-77%]) of all HIV-infected PWID on ART were virally suppressed. Access to harm reduction services in the past 12 months and lifetime receipt of opioid agonist treatment (OAT) had the strongest association with HIV status awareness. Additionally, OAT patients who were aware of HIV-positive status had 1.7 [1.2-2.3] times the odds of receiving ART. Being on ART for the last 6 months or longer increased odds to be virally suppressed; in contrast, missed recent doses of ART significantly decreased the odds of suppression. The HIV treatment cascade analysis for PWID in Ukraine revealed substantial gaps at each step and identified factors contributing to achievement of the outcomes. More intensive harm reduction outreach along with targeted case finding could help to fill the HIV awareness gap among PWID in Ukraine. Scale up of OAT and community-level linkage to care and ART adherence interventions are viable strategies to improve ART coverage and viral suppression among PWID.

Operational and contextual barriers to accessing supervised consumption services in two Canadian cities

BACKGROUND AND AIMS

While previous scholarship has documented barriers to Supervised Consumption Services (SCS) access, little is known about how Non-SCS-users perceive available, sanctioned SCS, and how such perceptions may hinder their SCS use. The objectives of this study were to examine: 1) barriers to accessing SCS for SCS-users and Non-SCS-users; and 2) the extent to which these barriers are consistent between groups.

METHODS

We conducted semi-structured interviews with 75 PWUD in two cities in Western Canada, Edmonton and Calgary, who may or may not have accessed available SCS. Participants were recruited on the streets near SCS via traditional fieldwork and snowball sampling. We employed a generalized prompt guide and asked a range of questions about how PWUD perceived and/or experienced SCS in the area. All interviews were digitally recorded, transcribed, thematically coded, and analysed.

RESULTS

Despite PWUD's generally positive perceptions of SCS, we identified several operational barriers to SCS access, including wait times and time limits, restrictions on injection assistance, and client bans from clinics. We also identified contextual barriers, including perceptions of the 'unnecessary' use of naloxone and police surveillance. Importantly, these barriers were consistent between SCS-users and Non-SCS-users, though some SCS-users actively worked to counter contextual barriers among peers.

CONCLUSION

Operational and contextual barriers to SCS use contribute to intermittent access for existing clients and preclude SCS access for others. Addressing such barriers may increase SCS uptake, thereby further extending the well-documented and critical reach of these harm reduction initiatives.

Engagement in primary health care among marginalized people who use drugs in Ottawa, Canada

BACKGROUND

There may be less primary health care engagement among people who use drugs (PWUD) than among the general population, even though the former have greater comorbidity and more frequent use of emergency department care. We investigated factors associated with primary care engagement among PWUD.

METHODS

The Participatory Research in Ottawa: Understanding Drugs (PROUD) cohort study meaningfully engaged and trained people with lived experience to recruit and survey marginalized PWUD between March-December 2013. We linked this survey data to provincial-level administrative databases held at ICES. We categorized engagement in primary care over the 2 years prior to survey completion as: not engaged (< 3 outpatient visits to the same family physician) versus engaged in care (3+ visits to the same family physician). We used multivariable logistic regression to determine factors associated with engagement in primary care.

RESULTS

Characteristics of 663 participants included a median age of 43 years, 76% men, and 67% living in the two lowest income quintile neighborhoods. Despite high comorbidity and a median of 4 (interquartile range 0-10) primary care visits in the year prior to survey completion, only 372 (56.1%) were engaged in primary care. Engagement was most strongly associated with the following factors: receiving provincial benefits, including disability payments (adjusted odds ratio [AOR] 4.14 (95% confidence interval [CI] 2.30 to 7.43)) or income assistance (AOR 3.69 (95% CI 2.00 to 6.81)), having ever taken methadone (AOR 3.82 (95% CI 2.28 to 6.41)), mental health comorbidity (AOR 3.43 (95% CI 2.19 to 5.38)), and having stable housing (AOR 2.09 (95% CI 1.29 to 3.38)).

CONCLUSIONS

Despite high comorbidity, engagement in primary care among PWUD was low. Our findings suggest that social care (housing, disability, and income support) and mental health care are associated with improved primary care continuity; integration of these care systems with primary care and opioid substitution therapy may lessen the significant morbidity and acute care use among PWUD.

Recognizing and responding to women experiencing homelessness with gendered and trauma-informed care

Background

The purpose of this study is to highlight the experiences of women who are often hidden in what we know and understand about homelessness, and to make policy and practice recommendations for women-centred services including adaptations to current housing interventions.

Methods

Three hundred survey interviews were conducted with people experiencing homelessness in Calgary, Alberta, Canada. The survey instrument measured socio-demographics, adverse childhood experiences, mental and physical health, and perceived accessibility to resources. Eighty-one women participants were identified as a subsample to be examined in greater depth. Descriptive statistics and logistic regressions were calculated to provide insight into women respondents’ characteristics and experiences of homelessness and how they differed from men’s experiences.

Results

Women’s experiences of homelessness are different from their male counterparts. Women have greater mental health concerns, higher rates of diagnosed mental health issues, suicidal thoughts and attempts, and adverse childhood trauma. The results should not be considered in isolation, as the literature suggests, because they are highly interconnected.

Conclusion

In order to ensure that women who are less visible in their experiences of homelessness are able to access appropriate services, it is important that service provision is both gender specific and trauma-informed. Current Housing First interventions should be adapted to ensure women’s safety is protected and their unique needs are addressed.

Willingness to participate in hepatitis C vaccine trials among socially marginalized people who use drugs

A major complicating factor for hepatitis C virus (HCV) vaccine clinical trial design and implementation is engagement and retention of people who use drugs (PWUD). Informed willingness to participate (WTP) in vaccine trials has emerged as a critical issue to describe, understand, and promote among populations at increased risk of communicable disease incidence. The present study addressed this topic by examining correlates of WTP among 320 socially marginalized PWUD as part of the Edmonton Drug Use and Health Survey (EDUHS). WTP was analyzed in relation to: gender, age, housing stability, ethnicity; self-reported hospital care in the past six months, self-reported injection drug use in the past 6 months, lifetime addiction treatment for alcohol or drugs, severity of drug use problems, and unmet healthcare needs. EDUHS participants reported high rates of current injection drug use (91%), and about two-thirds (67.3%) reported a lifetime HCV positive status. HCV positive respondents were older, had more severe substance use problems, and reported injecting drugs more frequently, compared to HCV negative respondents. Among the subsample of HCV negative respondents, 81% affirmed that they would be willing to enroll in a HCV vaccine prevention trial. Those reporting WTP were more likely to have had a recent hospital admission, to report more total unmet healthcare needs, and greater unmet needs for information, hospital care, and counseling, compared to HCV negative respondents not willing to enroll in a vaccine trial. No association was observed between WTP and other assessed variables. Results suggest that connecting PWUD not infected with HCV to local healthcare resources may be important in motivating vaccine trial participation.
