ABSTRACT

OBJECTIVES: Overdose prevention centers (OPCs) provide a safe place where people can consume preobtained drugs under supervision so that a life-saving medical response can be provided quickly in the event of an overdose. OPCs are programs that are established in Canada and have recently become legally sanctioned in only a few United States jurisdictions. METHODS: We conducted a systematic review that summarizes and identifies gaps of economic evidence on establishing OPCs in North America to guide future expansion of OPCs. RESULTS: We included 16 final studies that were evaluated with the Consolidated Health Economic Evaluation Reporting Standards and Drummond checklists. Eight studies reported cost-effectiveness results (eg, cost per overdose avoided or cost per quality-adjusted life-year), with 6 also including cost-benefit; 5 reported only cost-benefit results, and 3 cost offsets. Health outcomes primarily included overdose mortality outcomes or HIV/hepatitis C virus infections averted. Most studies used mathematical modeling and projected OPC outcomes using the experience of a single facility in Vancouver, BC. CONCLUSIONS: OPCs were found to be cost-saving or to have favorable cost-effectiveness or cost-benefit ratios across all studies. Future studies should incorporate the experience of OPCs established in various settings and use a greater diversity of modeling designs.

ABSTRACT

BACKGROUND: The Episodic Disability Questionnaire (EDQ) is a generic 35-item patient-reported outcome measure of presence, severity and episodic nature of disability. We assessed the measurement properties of the Episodic Disability Questionnaire (EDQ) with adults living with HIV. METHODS: We conducted a measurement study with adults living with HIV in eight clinical settings in Canada, Ireland, United Kingdom, and United States. We electronically administered the EDQ followed by three reference measures (World Health Organization Disability Assessment Schedule; Patient Health Questionnaire; Social Support Scale) and a demographic questionnaire. We administered the EDQ only 1 week later. We assessed the internal consistency reliability (Cronbach's alpha; > 0.7 acceptable), and test-retest reliability (Intra Class Correlation Coefficient; > 0.7 acceptable). We estimated required change in EDQ domain scores to be 95% certain that a change was not due to measurement error (Minimum Detectable Change (MDC95%)). We evaluated construct validity by assessing 36 primary hypotheses of relationships between EDQ scores and scores on the reference measures (> 75% hypotheses confirmed indicated validity). RESULTS: Three hundred fifty nine participants completed the questionnaires at time point 1, of which 321 (89%) completed the EDQ approximately 1 week later. Cronbach's alpha for internal consistency ranged from 0.84 (social domain) to 0.91 (day domain) for the EDQ severity scale, and 0.72 (uncertainty domain) to 0.88 (day domain) for the EDQ presence scale, and 0.87 (physical, cognitive, mental-emotional domains) to 0.89 (uncertainty domain) for the EDQ episodic scale. ICCs for test-retest reliability ranged from 0.79 (physical domain) to 0.88 (day domain) for the EDQ severity scale and from 0.71 (uncertainty domain) to 0.85 (day domain) for the EDQ presence scale. Highest precision was demonstrated in the severity scale for each domain (MDC95% range: 19-25 out of 100), followed by the presence (MDC95% range: 37-54) and episodic scales (MDC95% range:44-76). Twenty-nine of 36 (81%) construct validity hypotheses were confirmed. CONCLUSIONS: The EDQ possesses internal consistency reliability, construct validity, and test-retest reliability, with limited precision when administered electronically with adults living with HIV across in clinical settings in four countries. Given the measurement properties, the EDQ can be used for group level comparisons for research and program evaluation in adults living with HIV.

ABSTRACT

PURPOSE: Genomic sequencing can generate complex results, including variants of uncertain significance (VUS). In general, VUS should not inform clinical decision-making. This study aimed to assess the public's expected management of VUS. METHODS: An online, hypothetical survey was conducted among members of the Canadian public preceded by an educational video. Participants were randomized to 1 of 2 arms, VUS or pathogenic variant in a colorectal cancer gene, and asked which types of health services they expected to use for this result. Expected health service use was compared between randomization arms, and associations between participants' sociodemographic characteristics, attitudes, and medical history were explored. RESULTS: Among 1003 respondents (completion rate 60%), more participants expected to use each type of health service for a pathogenic variant than for a VUS. However, a considerable proportion of participants expected to request monitoring (73.4%) and consult health care providers (60.9%) for a VUS. There was evidence to support associations between expectation to use health services for a VUS with family history of genetic disease, family history of cancer, education, and attitudes toward health care and technology. CONCLUSION: Many participants expected to use health services for a VUS in a colorectal cancer predisposition gene, suggesting a potential disconnect between patients' expectations for VUS management and guideline-recommended care.

ABSTRACT

BACKGROUND: Emergency department visits and hospital admissions for opioid toxicity are opportunities to initiate opioid agonist therapy (OAT), which reduces morbidity and mortality in patients with opioid use disorder (OUD). The study objectives were to evaluate OAT initiation rates after a hospital encounter for opioid toxicity in Ontario, Canada, and determine whether publication of a 2018 Canadian OUD management guideline was associated with increased initiation. METHODS: We conducted a retrospective, population-based serial cross-sectional study of hospital encounters for opioid toxicity among patients with OUD between Jan. 1, 2013, and Mar. 31, 2020, in Ontario, Canada. The primary outcome was OAT initiation (methadone, buprenorphine-naloxone, or slow-release oral morphine) within 7 days of discharge, measured quarterly. We examined the impact of the release of the OUD management guideline on OAT initiation rates using Autoregressive Integrated Moving Average models. RESULTS: Among 20 702 hospital visits for opioid toxicity among patients with OUD, the median age was 35 years, and 65.1% were male. Over the study period, the percentage of visits leading to OAT initiation within 7 days rose from 1.7% or less (Q1 2013) to 5.6% (Q1 2020); however, the publication of the Canadian OUD management guideline was not associated with a significant increase in these rates (0.14% slope change, 95% confidence interval -0.11% to 0.38%; p = 0.3). INTERPRETATION: Among hospital encounters for opioid toxicity, despite rising prevalence over time, only 1 in 18 patients were dispensed OAT within a week of discharge in early 2020. These findings highlight missed opportunities to initiate therapies proven to reduce mortality in patients with OUD.

ABSTRACT

We investigated the association between fentanyl injection frequency and sharing of injection equipment among people who inject drugs. We surveyed 249 people who inject drugs in Toronto in 2019. We estimated predicted probabilities of associations between fentanyl injection frequency and injection risk practices. In prior 6 months, 117 (47.0%) of participants injected fentanyl daily, 49 (19.7%) less than daily, and 78 (31.3%) did not inject fentanyl. Participants who injected fentanyl daily shared syringes more often than those not injecting fentanyl (25.0% vs. 4.9%; χ2 = 11.54, p = 0.0007). Participants who injected fentanyl daily (42.4% vs. 11.3%; χ2 = 18.05, p < 0.0001) and less than daily (37.2% vs. 11.3%; χ2 = 5.88 p = 0.02) shared cookers more often than those not injecting fentanyl. Participants who injected fentanyl daily (30.2% vs. 9.7%; χ2 = 9.05, p = 0.003) and less than daily (30.3% vs. 9.7%; χ2 = 4.11, p = 0.04) shared filters more often than those not injecting fentanyl. No differences in probabilities of sharing equipment were detected between participants who injected fentanyl daily and less than daily. People using fentanyl reported injection practices that increased risk for infectious disease transmission.

ABSTRACT

BACKGROUND: Preliminary evidence suggests that people who inject drugs (PWID) may be at an increased risk of developing infective endocarditis (IE), hepatitis C virus (HCV) infection, and/or human immunodeficiency virus (HIV) infection from hydromorphone controlled-release formulation. The hypothesized mechanism is related to insolubility of the drug, which promotes reuse, leading to contamination of injecting equipment. However, this relationship has not been confirmed. We aimed to conduct a systematic review including adult PWID exposed to controlled-release hydromorphone and the risk of acquiring IE, HCV, and HIV. METHODS: We searched MEDLINE, EMBASE, and Evidence Based Medicine reviews from inception until September 2021. Following pilot testing, two reviewers conducted all screening of citations and full-text articles, as well as abstracted data, and appraised risk of bias using the Newcastle-Ottawa scale and Effective Practice and Organization of Care tool. Equity issues were examined using the PROGRESS-PLUS framework. Discrepancies were resolved consistently by a third reviewer. Meta-analysis was not feasible due to heterogeneity across the studies. RESULTS: After screening 3,231 citations from electronic databases, 722 citations from unpublished sources/reference scanning, and 626 full-text articles, five studies were included. Five were cohort studies, and one was a case-control study. The risk of bias varied across the studies. Two studies reported on gender, as well as other PROGRESS-PLUS criteria (race, housing, and employment). Three studies focused specifically on the controlled-release formulation of hydromorphone, whereas two studies focused on all formulations of hydromorphone. One retrospective cohort study found an association between controlled-release hydromorphone and IE, whereas a case-control study found no evidence of an association. One retrospective cohort study found an association between the number of hydromorphone controlled-release prescriptions and prevalence of HCV. None of the studies specifically reported on associations with HIV. DISCUSSION: Very few studies have examined the risk of IE, HCV, and HIV infection after exposure to controlled-release hydromorphone. Very low-quality and scant evidence suggests uncertainty around the risks of blood-borne infections, such as HCV and IE to PWID using this medication.

ABSTRACT

OBJECTIVE: To describe team-based care use among a cohort of people who use drugs (PWUD) and to determine factors associated with receipt of team-based care. DESIGN: A cohort study using survey data collected between March and December 2013. These data were then linked to provincial-level health administrative databases to assess patterns of primary care among PWUD in the 2 years before survey completion. SETTING: Ottawa, Ont. PARTICIPANTS: Marginalized PWUD 16 years of age or older. MAIN OUTCOME MEASURES: Patients were assigned to primary care models based on survey responses and then were categorized as attached to team-based medical homes, attached to non-team-based medical homes, not attached to a medical home, and no primary care. Descriptive statistics and multinomial logistic regression were used to determine associations between PWUD and medical home models. RESULTS: Of 663 total participants, only 162 (24.4%) received team-based care, which was associated with high school level of education (adjusted odds ratio [AOR] = 2.18; 95% CI 1.13 to 4.20), receipt of disability benefits (AOR = 2.47; 95% CI 1.22 to 5.02), and HIV infection (AOR = 2.88; 95% CI 1.28 to 6.52), and was inversely associated with recent overdose (AOR = 0.49; 95% CI 0.25 to 0.94). In comparison, 125 (18.8%) received non-team-based medical care, which was associated with university or college education (AOR = 2.31; 95% CI 1.04 to 5.15) and mental health comorbidity (AOR = 4.18; 95% CI 2.33 to 7.50), and was inversely associated with being detained in jail in the previous 12 months (AOR = 0.51; 95% CI 0.28 to 0.90). CONCLUSION: Although team-based, integrated models of care will benefit disadvantaged groups the most, few PWUD receive such care. Policy makers should mitigate barriers to physician care and improve integration across health and social services.

ABSTRACT

Variants of uncertain significance (VUS) are frequently reclassified but recontacting patients with updated results poses significant resource challenges. We aimed to characterize public and patient preferences for being recontacted with updated results. A discrete choice experiment (DCE) was administered to representative samples of the Canadian public and cancer patients. DCE attributes were uncertainty, cost, recontact modality, choice of results, and actionability. DCE data were analyzed using a mixed logit model and by calculating willingness to pay (WTP) for types of recontact. Qualitative interviews exploring recontact preferences were analyzed thematically. DCE response rate was 60% (n = 1003, 50% cancer patient participants). 31 participants were interviewed (11 cancer patients). Interviews revealed that participants expected to be recontacted. Quantitatively, preferences for how to be recontacted varied based on certainty of results. For certain results, WTP was highest for being recontacted by a doctor with updates ($1075, 95% CI: $845, $1305) and for contacting a doctor to request updates ($1038, 95% CI: $820, $1256). For VUS results, WTP was highest for an online database ($1735, 95% CI: $1224, $2247) and for contacting a doctor ($1705, 95% CI: $1102, $2307). Qualitative data revealed that preferences for provider-mediated recontact were influenced by trust in healthcare providers. Preferences for a database were influenced by lack of trust in providers and desire for control. Patients and public participants support an online database (e.g. patient portal) to recontact for VUS, improving feasibility, and provider-mediated recontact for certain results, consistent with usual care.

ABSTRACT

ABSTRACT: We surveyed 383 men who have sex with men attending sexual health clinics regarding interest in hypothetical preexposure prophylaxis against herpes simplex virus. Overall interest was 62.5% and was associated with the number of different sexually transmitted infections previously diagnosed (adjusted odds ratio, 1.9; 95% confidence interval, 1.5-2.6) and previous HIV preexposure prophylaxis use (adjusted odds ratio, 2.9; 95% confidence interval, 1.1-8.3).

ABSTRACT

BACKGROUND: Events associated with the COVID-19 pandemic, such as physical distancing, closure of community services, postponement of health appointments, and loss of employment can lead to social isolation, financial uncertainty, and interruption of antiretroviral adherence, resulting in additional health-related challenges (disability) experienced among adults living with chronic illness such as HIV. 'Living strategies' is a concept derived from the perspectives of people living with HIV, defined as behaviors, attitudes and beliefs adopted by people living with HIV to help deal with disability associated with HIV and multi-morbidity. Our aim was to describe disability among adults living with HIV and self-care living strategies used during the COVID-19 pandemic. METHODS: Adults living with HIV in Toronto, Ontario, Canada, including some with pre-pandemic HIV Disability Questionnaire (HDQ) data, completed a cross-sectional web-based survey between June-August 2020. The survey included the HDQ and questions about self-care living strategy use during the pandemic. We compared disability (HDQ) scores prior to versus during the pandemic using paired t-tests. We reported the proportion of participants who engaged in various living strategies at least 'a few times a week' or 'everyday' during the pandemic. RESULTS: Of the 63 respondents, 84% were men, median age 57 years, and 62% lived alone. During the pandemic the greatest disability severity was in the uncertainty [median 30; Interquartile range (IQR): 16, 43] and mental-emotional (25; IQR: 14, 41) domains. Among the 51 participants with pre-pandemic data, HDQ severity scores were significantly greater (worse) during the pandemic (vs prior) in all domains. Greatest change from prior to during the pandemic was in the mental-emotional domain for presence (17.7; p < 0.001), severity (11.4; p < 0.001), and episodic nature (9.3; p < 0.05) of disability. Most participants (> 60%) reported engaging a 'few times a week' or 'everyday' in self-care strategies associated with maintaining sense of control and adopting positive attitudes and beliefs. CONCLUSIONS: People living with HIV reported high levels of uncertainty and mental-emotional health challenges during the pandemic. Disability increased across all HDQ dimensions, with the greatest worsening in the mental-emotional health domain. Results provide an understanding of disability and self-care strategy use during the COVID-19 pandemic.

ABSTRACT

BACKGROUND: Spotting is an informal practice among people who use drugs (PWUD) where they witness other people using drugs and respond if an overdose occurs. During COVID-19 restrictions, remote spotting (e.g., using a telephone, video call, and/or a social media app) emerged to address physical distancing requirements and reduced access to harm reduction and/or sexually transmitted blood borne infection (STBBI's) prevention services. We explored spotting implementation issues from the perspectives of spotters and spottees. METHODS: Research assistants with lived/living expertise of drug use used personal networks and word of mouth to recruit PWUD from Ontario and Nova Scotia who provided or used informal spotting. All participants completed a semi-structured, audio-recorded telephone interview about spotting service design, benefits, challenges, and recommendations. Recordings were transcribed and thematic analysis was used. RESULTS: We interviewed 20 individuals between 08/2020-11/2020 who were involved in informal spotting. Spotting was provided on various platforms (e.g., telephone, video calls, and through texts) and locations (e.g. home, car), offered connection and community support, and addressed barriers to the use of supervised consumption sites (e.g., location, stigma, confidentiality, safety, availability, COVID-19 related closures). Spotting calls often began with setting an overdose response plan (i.e., when and who to call). Many participants noted that, due to the criminalization of drug use and fear of arrest, they preferred that roommates/friends/family members be called instead of emergency services in case of an overdose. Both spotters and spottees raised concerns about the timeliness of overdose response, particularly in remote and rural settings. CONCLUSION: Spotting is a novel addition to, but not replacement for, existing harm reduction services. To optimize overdose/COVID-19/STBBI's prevention services, additional supports (e.g., changes to Good Samaritan Laws) are needed. The criminalization of drug use may limit uptake of formal spotting services.

ABSTRACT

BACKGROUND: Canada launched the Syrian Refugee Resettlement Initiative in 2015 and resettled over 40,000 refugees. AIM: To evaluate the prevalence of depression-level symptoms at baseline and one year post-resettlement and analyze its predictors. METHODS: Data come from the Syrian Refugee Integration and Long-term Health Outcomes in Canada study (SyRIA.lth) involving 1924 Syrian refugees recruited through a variety of community-based strategies. Data were collected using structured interviews in 2017 and 2018. Depression symptoms were measured using Patient Health Questionnaire 9 (PHQ-9). Analysis for associated factors was executed using multinomial logistic regression. RESULTS: Mean age was 38.5 years (SD 13.8). Sample included 49% males and 51% females settled in Ontario (48%), Quebec (36%) and British Columbia (16%). Over 74% always needed an interpreter, and only 23% were in employment. Prevalence of depression-level symptoms was 15% at baseline and 18% in year-2 (p < 0.001). Significant predictors of depression-level symptoms at year-2 were baseline depression, sponsorship program, province, poor language skills, lack of satisfaction with housing conditions and with health services, lower perceived control, lower perceived social support and longer stay in Canada. CONCLUSION: Increase in depression-level symptoms deserves attention through focusing on identified predictors particularly baseline depression scores, social support, perceived control and language ability.

ABSTRACT

BACKGROUND: We assessed the acceptability of doxycycline-based syphilis pre-exposure and post-exposure prophylaxis (PrEP/PEP) as well as human immunodeficiency virus (HIV) PrEP/PEP in gay, bisexual, and other men who have sex with men (gbMSM). METHODS: We recruited gbMSM from Toronto and Vancouver sexually transmitted infection (STI) clinics during routine visits from June 2018 to August 2018. We analyzed data using descriptive statistics and constructed multivariable logistic regression models for willingness to use syphilis and HIV PrEP and PEP respectively. RESULTS: Among 424 participants (56.4% Toronto, 43.6% Vancouver), median (interquartile range [IQR]) age was 31.0 years (26.0-39.0 years), 61.7% had completed postsecondary education and 54.4% were white. Median (IQR) number of male partners in the past 6 months was 6.0 (3.0-13.0), and 18.2% had 1 or more prior syphilis diagnosis. 60.1%/44.1% indicated willingness to use syphilis PEP/PrEP; 36.6% were unwilling to use either. Among HIV-negative participants, 74.0% and 75.2% were willing to use HIV PrEP and PEP, respectively. Most participants were familiar with antibiotic resistance (89.0%) and agreed that syphilis rates are rising in Canada (68.2%), but only 55.4% believed they were at risk for syphilis. Agreement with the latter statement was associated with willingness to use syphilis PrEP (adjusted odds ratio [aOR], 1.6; 95% confidence interval [95%CI], 1.0-2.5), as was previous/existing HIV PrEP use (aOR, 2.2; 95% CI, 1.1-4.3) and being "very concerned" about STI acquisition (aOR, 1.9; 95% CI, 1.0-3.4). Odds of being willing to use syphilis PEP were higher in Toronto versus Vancouver (aOR, 2.0; 95% CI, 1.2-3.4) and increased with the number of different STIs previously diagnosed (aOR, 1.4; 95% CI, 1.2,1.7). CONCLUSIONS: There is considerable interest in syphilis PrEP/PEP in gbMSM attending Toronto/Vancouver STI clinics.

ABSTRACT

BACKGROUND: Operative approaches for Hinchey III diverticulitis include the Hartmann procedure, primary resection and anastomosis, and laparoscopic lavage. Several randomized controlled trials and meta-analyses have compared these approaches; however, results are conflicting and previous studies have not captured the complexity of balancing surgical risks and quality of life. OBJECTIVE: This study aimed to determine the optimal operative strategy for patients with Hinchey III sigmoid diverticulitis. DESIGN: We developed a Markov cohort model, incorporating perioperative morbidity/mortality, emergency and elective reoperations, and quality-of-life weights. We derived model parameters from systematic reviews and meta-analyses, where possible. We performed a second-order Monte Carlo probabilistic sensitivity analysis to account for joint uncertainty in model parameters. SETTING: This study measured outcomes over patients' lifetime horizon. PATIENTS: The base case was a simulated cohort of 65-year-old patients with Hinchey III diverticulitis. A scenario simulating a cohort of highly comorbid 80-year-old patients was also planned. INTERVENTIONS: Hartmann procedure, primary resection and anastomosis (with or without diverting ileostomy), and laparoscopic lavage were performed. MAIN OUTCOME MEASURES: Quality-adjusted life years were the primary outcome measured. RESULTS: Following surgery for Hinchey III diverticulitis, 39.5% of patients who underwent the Hartmann procedure, 14.3% of patients who underwent laparoscopic lavage, and 16.7% of patients who underwent primary resection and anastomosis had a stoma at 12 months. After applying quality-of-life weights, primary resection and anastomosis was the optimal operative strategy, yielding 18.0 quality-adjusted life years; laparoscopic lavage and the Hartmann procedure yielded 9.6 and 13.7 fewer quality-adjusted life months. A scenario analysis for elderly, highly comorbid patients could not be performed because of a lack of high-quality evidence to inform model parameters. LIMITATIONS: This model required assumptions about the long-term postoperative course of patients who underwent laparoscopic lavage because few long-term data for this group have been published. CONCLUSIONS: Although the Hartmann procedure is widely used for Hinchey III diverticulitis, when considering both surgical risks and quality of life, both laparoscopic lavage and primary resection and anastomosis provide greater quality-adjusted life years for patients with Hinchey III diverticulitis, and primary resection and anastomosis appears to be the optimal approach.

ESTRATEGIA OPERATIVA ÓPTIMA EN DIVERTICULITIS HINCHEY III DE SIGMOIDES: UN ANÁLISIS DE DECISION: Los enfoques quirúrgicos para la diverticulitis Hinchey III incluyen el procedimiento de Hartmann, la resección primaria y anastomosis, y el lavado laparoscópico. Varios ensayos controlados aleatorios y metanálisis han comparado estos enfoques; sin embargo, los resultados son contradictorios y los estudios previos no han captado la complejidad de equilibrar los riesgos quirúrgicos y la calidad de vida.Determinar la estrategia operativa óptima para pacientes con diverticulitis Hinchey III de sigmoides.Desarrollamos un modelo de cohorte de Markov, incorporando morbilidad / mortalidad perioperatoria, reoperaciones electivas y de emergencia, y pesos de calidad de vida. Derivamos los parámetros del modelo de revisiones sistemáticas y metaanálisis, cuando fue posible. Realizamos un análisis de sensibilidad probabilístico Monte Carlo de segundo orden para tener en cuenta la incertidumbre conjunta en los parámetros del modelo.Seguimiento de por vida.El caso base fue una cohorte simulada de pacientes de 65 años con diverticulitis de Hinchey III. También se planeó un escenario que simulaba una cohorte de pacientes de 80 años altamente comórbidos.Procedimiento de Hartmann, resección primaria y anastomosis (con o sin desviación de ileostomía) y lavado laparoscópico.Años de vida ajustados por calidad.Después de la cirugía para la diverticulitis de Hinchey III, el 39.5% de los pacientes que se sometieron al procedimiento de Hartmann, el 14.3% de los pacientes que se sometieron a un lavado laparoscópico, y el 16.7% de los pacientes que se sometieron a resección primaria y anastomosis tuvieron un estoma a los 12 meses. Después de aplicar el peso de la calidad de vida, la resección primaria y la anastomosis fueron la estrategia operativa óptima, que dio como resultado 18.0 años de vida ajustados en función de la calidad; el lavado laparoscópico y el procedimiento de Hartmann arrojaron 9.6 y 13.7 meses de vida ajustados en función de la calidad, respectivamente. No se pudo realizar un análisis de escenarios para pacientes de edad avanzada altamente comórbidos debido a la falta de evidencia de alta calidad para informar los parámetros del modelo.Este modelo requirió suposiciones sobre el curso postoperatorio a largo plazo de pacientes que se sometieron a lavado laparoscópico, ya que se han publicado pocos datos a largo plazo para este grupo.Aunque el procedimiento de Hartmann se usa ampliamente para la diverticulitis de Hinchey III, cuando se consideran tanto los riesgos quirúrgicos como la calidad de vida, tanto el lavado laparoscópico como la resección primaria y la anastomosis proporcionan una mayor calidad de años de vida ajustada para los pacientes con diverticulitis de Hinchey III y la resección primaria y anastomosis parece ser el enfoque óptimo.

ABSTRACT

PURPOSE: With reduced mortality of neonatal conditions, health-related quality of life (HRQOL) has become an important clinical outcome. However, since the meaning of HRQOL in dependent, non-autonomous infants and neonates remains largely undefined, HRQOL measurement and economic evaluation are limited due to the lack of age-specific methodology. The objective was to construct a conceptual framework of neonatal and infant HRQOL (NIHRQOL) which identifies factors relevant to the neonate and infant, their relationship with each other and the caregiving environment. METHODS: Using qualitative methods, a concept was developed based on in-depth analysis of verbatim records of two focus groups (6 caregivers, 6 healthcare providers) and five interviews with caregivers of chronically ill neonates/infants (n = 2), and healthcare professionals of a pediatric tertiary healthcare center (n = 3). Two analysts independently performed thematic analysis using an inductive and contextual approach. RESULTS: The majority of participants regarded NIHRQOL as an individual entity, which was closely related and strongly influenced by caregivers and family. It may be gauged by the perceived degree of effort required to achieve expected normalcy in everyday life for the neonate/infant and its family. The importance of individual HRQOL factors is developmental stage-dependent. CONCLUSION: Neonatal and infant HRQOL is a multidimensional, multilayered and interconnected concept, where the child's needs contribute most directly, and the caregiver's and society's ability to meet those needs characterize the interdependence between the child and its caregiving environment. Developmental stage-specific HRQOL instruments for premature and mature neonates, and infants are warranted to allow for valid HRQOL measurement.

ABSTRACT

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.

ABSTRACT

BACKGROUND: The operation of supervised consumption services (SCS), programs that offer supervised locations for the consumption of drugs such as heroin, other opioids, cocaine, other stimulants, and other drugs, is contingent on cooperative relationships with police. In this manuscript, we focus on an under studied topic: how active duty police officers understand their role with respect to SCS, and their recommendations for improving relationships with these programs. Methods: During 2018, we audio-recorded and transcribed focus group discussions conducted in four police divisions with 26 police constables and 3 officers of other ranks in Toronto, Canada. Officers were asked about their roles relative to SCS, perceived training needs, and how to build cooperative relationships with SCS. We followed an iterative thematic approach to analyze the data. Results: Participants in three divisions were unclear about their roles, duties, and policy governing policing of SCS. Participants in the fourth division had received instructions from the division commander to observe a "distance and discretion policy". However, these participants believed that developing familiarity with the new SCS, instead of keeping a distance, would be a more effective approach to building working relationships with staff, clients, and the local community. There was nearly unanimous skepticism about the willingness of SCS workers to work cooperatively with the police. These perceptions were commonly linked to previous negative experiences with harm reduction workers and, in some cases, staff at the new SCS. Several participants also linked problems in communication to fundamental differences between the philosophies or worldviews of SCS staff versus those of police. Conclusions: Building collaborative SIS-police relationships can be assisted by demystifying the operation of SCS for police, articulating policies, and working toward mutual respect.

ABSTRACT

BACKGROUND: Health utility assessments are important for economic evaluations but few instruments have been validated in homeless people with mental illness. We examined the convergent validity of the EuroQol-5 Dimension 3-level questionnaire (EQ-5D-3L) as a measure of quality of life in homeless adults with mental illness. METHODS: Data were from Toronto participants in At Home/Chez Soi, a 24-month randomized controlled trial of Housing First (immediate access to scattered site housing and mental health support services) compared to treatment as usual for homeless adults with a mental disorder (n = 575). Participants completed the EQ-5D-3L at 6 month intervals. We tested convergent validity, hypothesizing strong correlation (r > 0.6) with the Lehman Quality of Life Interview 20 (QOLI-20) index and moderate correlations (r > 0.3) with the Colorado Symptom Index (CSI), Recovery Assessment Scale (RAS), and number of comorbidities. We also examined correlations between EQ-5D-3L scores and the QOLI-20 over time using a linear mixed-effects model. RESULTS: The EQ-5D-3L was not strongly correlated with the QOLI-20 (r ranged from 0.31-0.52 at various time points). The EQ-5D-3L was moderately correlated with the CSI, RAS, and number of comorbidities. The Snijders/Bosker r2 for longitudinal validity between the EQ-5D-3L and QOLI-20 within subjects over time was 0.2094 (square-root r = 0.4576). CONCLUSIONS: The EQ-5D-3L did not demonstrate strong convergent validity in homeless people with mental illness but was moderately correlated with several instruments. Further research is warranted to determine the optimal method for measuring health utilities in this population.

ABSTRACT

BACKGROUND: Chronic hepatitis C virus (HCV) infection is common among people who inject drugs (PWID) and is associated with morbidity and premature death. Although HCV can be cured, treatment may be inaccessible. We studied HCV testing, status and treatment among marginalized people who use drugs in Ottawa, Canada, a setting with universal insurance coverage for physician services. METHODS: We analyzed data from the Participatory Research in Ottawa: Understanding Drugs study, a cross-sectional, peer-administered survey of people who use drugs from 2012 to 2013. We linked responses to population-based health administrative databases and used multivariable Poisson regression to identify factors independently associated with self-reported HCV testing, self-reported positive HCV status, and database-determined engagement in HCV treatment. RESULTS: Among 663 participants, 562 (84.8%) reported testing for HCV and 258 (45.9%) reported HCV-positive status. In multivariable analysis, HCV-positive status was associated with female gender (RR 1.27; 95%CI 1.04 to 1.55), advancing age (RR 1.03/year; 95%CI 1.02 to 1.04), receiving disability payments (RR 1.42; 95%CI 1.06 to 1.91), injecting drugs (RR 5.11; 95%CI 2.64 to 9.91), ever injecting with a used needle (RR 1.30; 95%CI 1.12 to 1.52), and ever having taken methadone (RR 1.26; 95%CI 1.05 to 1.52). Of HCV positive participants, 196 (76%) were engaged in primary care but only 23 (8.9%) had received HCV therapy. Conclusions/Importance: Although HCV testing and positive status rates are high among PWID in our study, few have received HCV treatment. Innovative initiatives to increase access to HCV treatment for PWID are urgently needed.

ABSTRACT

Cervical cancer caused by oncogenic types of the human papillomavirus (HPV) is of concern among HIV-positive women due to impairment of immune responses required to control HPV infection. Our objectives were to describe patterns of cervical cancer screening using Pap cytology testing among HIV-positive women in Ontario, Canada from 2008 to 2013 and to identify factors associated with adequate screening. We conducted a retrospective, population-based cohort study among screen-eligible HIV-positive women using provincial administrative health data. We estimated annual proportions tested and reported these with 95% confidence intervals (CI). Next, using person-years as the unit of analysis, we identified factors associated with annual Pap testing using log-binomial regression. A total of 2271 women were followed over 10,697 person-years. In 2008, 34.0% (95%CI 31.1-37.0%) had a Pap test. By 2013, the proportion of HIV-positive women tested was 25.9% (95%CI 23.6-28.2%). Women who were most likely to undergo testing were younger, were immigrants from countries with generalized HIV epidemics, lived in the highest income neighbourhoods, had a female primary care physician, had two or more encounters per year with an infectious disease or internal medicine specialist, and had greater comorbidity. Nearly three in four HIV-positive women were under-screened despite all having universal insurance for medically-necessary services. Annual Pap testing decreased following the 2011-2013 release of new guidelines for a lengthened screen interval for average risk women and a billing disincentive. Clinic-based intervention such as physician alerts or reminders may be needed to improve screening coverage among HIV-positive women.
