Developing a patient-reported experience questionnaire with and for people who use drugs: A community engagement process in Vancouver's Downtown Eastside

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.

Involvement of people who use alcohol and other drug services in the development of patient-reported measures of experience: A scoping review

INTRODUCTION

Patient-reported measures that assess satisfaction and experience are increasingly utilised in healthcare sectors, including the alcohol and other drug (AOD) sector. This scoping review identifies how and to what extent people accessing AOD services have been involved in the development of satisfaction and experience measures to date.

METHODS

PubMed, EMBASE, CINAHL, Scopus, ProQuest, Google and Google Scholar were searched. Included papers described the development and/or implementation of a multiple-item measure of patient-reported experience or satisfaction specifically for people accessing AOD treatment and/or harm reduction programmes. If there was more than one paper, key papers were chosen that described each measure. The method of development, including service user involvement, was assessed against a framework generated for this review. Two reviewers were involved at each stage.

RESULTS

Thirty measures-23 satisfaction and 7 experience-were identified. Sixteen measures reported some level of involvement by people accessing AOD services in their development, although, for most measures, at a relatively low level. This involvement increased over the time span of the review becoming more frequent in later years. Only four measures were developed for use in harm reduction-specific settings, and fewer than half reported undertaking analysis of underlying scale structure and constructs.

CONCLUSION

Several gaps could be addressed to enhance the measurement of patient-centred care in the AOD sector, including: developing experience measures for use in harm reduction settings and across various AOD settings in a service system; improved reporting of psychometric properties of these measures and increasing commitment to the meaningful involvement of AOD service users in measure development.

PATIENT OR PUBLIC CONTRIBUTION

This scoping review is part of a broader codesign project that involves a partnership between the peak organisation for AOD services and the peer-based AOD consumer organisation in the Australian Capital Territory, Australia. These organisations are working closely together to engage with AOD service users, service providers and policy makers in this codesign project. As such, the Executive Director of the peer-based AOD consumer organisation is involved as a co-author of this scoping review.

Roles, outcomes, and enablers within research partnerships: A rapid review of the literature on patient and public involvement and engagement in health research

BACKGROUND

Recent studies mention a need to investigate partnership roles and dynamics within patient and public involvement and engagement (PPIE) in health research, and how impact and outcomes are achieved. Many labels exist to describe involvement processes, but it is unknown whether the label has implications on partnerships and outcomes. This rapid review investigates how roles between patients, relatives and researchers in a broad variety of PPIE activities in health research are described in peer reviewed papers and explores what enables these partnerships.

METHODS

Rapid review of articles published between 2012 and February 2022 describing, evaluating, or reflecting on experiences of PPIE in health research. All research disciplines and research areas were eligible. Four databases (Medline, Embase, PsychInfo and CINAHL) were searched between November 2021 and February 2022. We followed PRISMA guidelines and extracted descriptive factors: year, origin, research area and discipline, study focus, framework used and co-authorship. On a selection of articles, we performed a narrative analysis of partnership roles using Smits et al.'s. Involvement Matrix. Lastly, we performed a meta synthesis of reported enablers and outcomes of the partnerships. Patients and Relatives (PRs) have been involved in the whole rapid review process and are co-authors of this article.

RESULTS

Seventy articles from various research disciplines and areas were included. Forty articles were selected for a narrative analysis of the role description of PRs and researchers, and a meta synthesis of enablers and outcomes. Most articles described researchers as decision-makers throughout the research cycle. PRs most often were partners when they were included as co-authors; they were mostly partners in the design, analysis, write-up, and dissemination stages. Enablers of partnerships included: PR training, personality of PRs and communication skills, trust, remuneration and time.

CONCLUSIONS

Researchers' decision-making roles gives them control of where and when to include PRs in their projects. Co-authorship is a way of acknowledging patients' contributions which may lead to legitimation of their knowledge and the partnership. Authors describe common enablers, which can help future partnership formation.

Comparative effectiveness of urine drug screening strategies alongside opioid agonist treatment in British Columbia, Canada: a population-based observational study protocol

INTRODUCTION

Urine drug tests (UDTs) are commonly used for monitoring opioid agonist treatment (OAT) responses, supporting the clinical decision for take-home doses and monitoring potential diversion. However, there is limited evidence supporting the utility of mandatory UDTs-particularly the impact of UDT frequency on OAT retention. Real-world evidence can inform patient-centred approaches to OAT and improve current strategies to address the ongoing opioid public health emergency. Our objective is to determine the safety and comparative effectiveness of alternative UDT monitoring strategies as observed in clinical practice among OAT clients in British Columbia, Canada from 2010 to 2020.

METHODS AND ANALYSIS

We propose a population-level retrospective cohort study of all individuals 18 years of age or older who initiated OAT from 1 January 2010 to 17 March 2020. The study will draw on eight linked health administrative databases from British Columbia. Our primary outcomes include OAT discontinuation and all-cause mortality. To determine the effectiveness of the intervention, we will emulate a 'per-protocol' target trial using a clone censoring approach to compare fixed and dynamic UDT monitoring strategies. A range of sensitivity analyses will be executed to determine the robustness of our results.

ETHICS AND DISSEMINATION

The protocol, cohort creation and analysis plan have been classified and approved as a quality improvement initiative by Providence Health Care Research Ethics Board and the Simon Fraser University Office of Research Ethics. Results will be disseminated to local advocacy groups and decision-makers, national and international clinical guideline developers, presented at international conferences and published in peer-reviewed journals electronically and in print.

Suboptimal nonmedical qualities of primary care linked with care avoidance among people who use drugs in a Canadian setting amid an integrated health care reform

BACKGROUND

People who use unregulated drugs (PWUD) often face significant barriers to-and thereby avoid seeking-health care. In Vancouver, Canada, a neighborhood-wide health care system reform began in 2016 to improve health care delivery and quality. In the wake of this reform, we sought to determine the prevalence of health care avoidance and its association with emergency department use among PWUD in this setting and examine patient-reported nonmedical qualities of health care ("responsiveness").

METHODS

The study derived data from two prospective cohort studies of community-recruited PWUD in Vancouver in 2017-18. Responsiveness was ascertained by the World Health Organizations' standardized measurements and we evaluated seven domains of responsiveness (dignity, autonomy, communication, confidentiality, prompt attention, choice of provider, and quality of basic amenities). The study used Pearson chi-squared test to examine differences in responsiveness between those who did and did not avoid care. The study team used multivariable logistic regression to determine the relationship between care avoidance due to past mistreatment and emergency department use, adjusting for potential confounders.

RESULTS

Among 889 participants, 520 (58.5%) were male, 204 (22.9%) reported avoiding health care, most commonly for chronic pain (47.4%). Overall, 6.6% to 36.2% reported suboptimal levels (i.e., not always meeting the expected quality) across all seven measured domain of responsiveness. Proportions reporting suboptimal qualities were significantly higher among those who avoided care than those who did not across all domains, including care as soon as wanted (51.0% vs. 31.8%), listened to carefully (44.1% vs. 20.4%), and involved in health care decision-making (27.9% vs. 12.7%) (all p < 0.05). In multivariable analyses, avoidance of health care was independently associated with self-reported emergency department use (adjusted odds ratio = 1.49; 95% confidence interval:1.01-2.19).

CONCLUSION

We found that almost a quarter of our sample of PWUD avoided seeking health care due to past mistreatment, and all seven measured domains of responsiveness were suboptimal and linked with avoidance. Individuals who reported avoidance of health care were significantly more likely to report emergency department use. Multi-level interventions are needed to remedy the suboptimal qualities of health care and thereby reduce care avoidance.

The overdose epidemic: a study protocol to determine whether people who use drugs can influence or shape public opinion via mass media

BACKGROUND

We are currently witnessing an ongoing drug overdose death epidemic in many nations linked to the distribution of illegally manufactured potent synthetic opioids. While many health policy makers and researchers have focused on the root causes and possible solutions to the current crisis, there has been little focus on the power of advocacy and community action by people who use drugs (PWUDs). Specifically, there has been no research on the role of PWUDs in engaging and influencing mass media opinion.

METHODS

By relying on one of the longest and largest peer-run drug user advocacy groups in the world, the Vancouver Area Network of Drug Users (VANDU), newspaper articles, television reports, and magazines that VANDU or its members have been directly involved in will be identified via two data bases (the Canadian Newsstream & Google News). The news articles and videos related to the health of PWUDs and issues affecting PWUDs from 1997 to the end of 2020 will be analyzed qualitatively using Nvivo software.

DISCUSSION

As our communities are entering another phase of the drug overdose epidemic, acknowledging and partnering with PWUDs could play an integral part in advancing the goals of harm reduction, treatment, and human rights.

Development and validation of health system performance measures for opioid use disorder in British Columbia, Canada

BACKGROUND

Performance measurement provides an evidence-based means to inform development of interventions to improve the quality of care for people who use opioids. We aimed to develop and assess the predictive validity of health system performance measures for opioid use disorder (OUD) in British Columbia (BC), Canada.

METHODS

Performance measures were generated using retrospective population-level administrative datasets (both provincial and regional) and publicly-reported retrospective data according to four domains (care engagement, clinical guideline compliance, integration, and healthcare utilization). The adjusted odds ratio was estimated via generalized linear mixed models to determine predictive validity for all-cause hospitalization or mortality within 6 months of measurement.

FINDINGS

A total of 102 performance measures were constructed. We identified 55,470 diagnosed PWOUD, and 39,456 ever engaged in opioid agonist treatment (OAT). We found divergent rates of treatment for concurrent conditions (7.4% for alcohol use disorder to 80.1% for HIV/AIDS), low levels of linkage to OAT and other outpatient care following acute care, and increasing levels of service provision, including increases in OAT prescribers and pharmacies, naloxone kit distribution and overdose prevention site visitation. Our analyses on the predictive validity measures largely supported a priori hypotheses on the direction of effect on the outcome.

CONCLUSIONS

We identified a range of priorities to improve the quality of care for PWOUD, with critical gaps in linkage to care through acute care settings and long-term engagement in OAT. The proposed measures can be derived for geographic and clinical subgroups and updated over time, providing a basis to monitor and evaluate efforts to address the public health burden of OUD.

Preliminary psychometric evaluation of the patient reported experience measure for addiction treatment (PREMAT)

INTRODUCTION

Patient-reported experience measures (PREMs) are recommended for use in evaluating person-centred care. To date, a PREM has not been validated for residential alcohol and other drug (AOD) treatment. Utilising items developed through a previously published qualitative study informing the development of the PREM for Addiction Treatment (PREMAT), the current study conducted a psychometric evaluation and validation of the PREMAT.

DESIGN AND METHODS

Cross-sectional survey data were collected from six Australian residential AOD treatment facilities (N = 178). Psychometric evaluation included examining the factor structure, internal consistency, and construct validity of the PREMAT. Test re-test reliability was conducted at one treatment site (n = 24).

RESULTS

The total PREMAT score demonstrated strong internal consistency (α = 0.91). Principle components analysis identified six factors (all α > 0.72). The PREMAT total score and factor scores were negatively skewed. Concurrent validity was demonstrated by strong positive correlations with measures of satisfaction (ρ = 0.81, Client Satisfaction Questionnaire-8; ρ = 0.78, Treatment Perceptions Questionnaire), and divergent validity was demonstrated with weaker correlations with Drug-Taking Confidence Questionnaire (ρ = 0.25) and Kessler-10 (ρ = -0.20). Test-retest reliability was strong for the total PREMAT (ρ = 0.89).

DISCUSSION AND CONCLUSIONS

Results support the use of the PREMAT as a valid measure of experience in residential AOD treatment settings. Future research should examine the use of the PREMAT across the course of treatment to examine if experience is related to client characteristics, outcome, dropout or re-engagement in treatment.

Evaluating health service outcomes of public involvement in health service design in high-income countries: a systematic review

BACKGROUND

Internationally, it is expected that health services will involve the public in health service design. Evaluation of public involvement has typically focused on the process and experiences for participants. Less is known about outcomes for health services. The aim of this systematic review was to a) identify and synthesise what is known about health service outcomes of public involvement and b) document how outcomes were evaluated.

METHODS

Searches were undertaken in MEDLINE, EMBASE, The Cochrane Library, PsycINFO, Web of Science, and CINAHL for studies that reported health service outcomes from public involvement in health service design. The review was limited to high-income countries and studies in English. Study quality was assessed using the Mixed Methods Appraisal Tool and critical appraisal guidelines for assessing the quality and impact of user involvement in health research. Content analysis was used to determine the outcomes of public involvement in health service design and how outcomes were evaluated.

RESULTS

A total of 93 articles were included. The majority were published in the last 5 years, were qualitative, and were located in the United Kingdom. A range of health service outcomes (discrete products, improvements to health services and system/policy level changes) were reported at various levels (service level, across services, and across organisations). However, evaluations of outcomes were reported in less than half of studies. In studies where outcomes were evaluated, a range of methods were used; most frequent were mixed methods. The quality of study design and reporting was inconsistent.

CONCLUSION

When reporting public involvement in health service design authors outline a range of outcomes for health services, but it is challenging to determine the extent of outcomes due to inadequate descriptions of study design and poor reporting. There is an urgent need for evaluations, including longitudinal study designs and cost-benefit analyses, to fully understand outcomes from public involvement in health service design.

High prevalence of unmet healthcare need among people who use illicit drugs in a Canadian setting with publicly-funded interdisciplinary primary care clinics

BACKGROUND

People who use illicit drugs (PWUD) experience significant barriers to healthcare. However, little is known about levels of attachment to primary care (defined as having a regular family doctor or clinic they feel comfortable with) and its association with unmet healthcare needs in this population. In a Canadian setting that features novel publicly-funded interdisciplinary primary care clinics, we sought to examine the prevalence and correlates (including attachment to primary care) of unmet healthcare needs among PWUD. Methods: Data were derived from two prospective cohort studies of PWUD in Vancouver, Canada between December 2017 and November 2018. Multivariable logistic regression was used to identify factors associated with self-reported unmet healthcare needs among participants reporting any health issues. Results: In total, 743 (83.6%) of 889 eligible participants reported attachment to primary care and 220 (24.7%) reported an unmet healthcare need. In multivariable analyses, attachment to primary care at an integrated care clinic (adjusted odds ratio [AOR] = 0.14; 95% Confidence Interval [CI]: 0.06-0.34) was negatively associated with an unmet healthcare need, while being treated poorly at a healthcare facility (AOR = 5.50; 95% CI: 3.59-8.60) and self-reported chronic pain (AOR = 2.00, 95% CI: 1.30-3.01) were positively associated with an unmet healthcare need. Conclusion: Despite the high level of attachment to primary care, a quarter of our sample reported an unmet healthcare need. Our findings suggest that multi-level interventions are required to address the unmet need, including pain management and integrated care, to support PWUD with complex health needs.

Non-disclosure of drug use in outpatient health care settings: Findings from a prospective cohort study in Vancouver, Canada

BACKGROUND

Illicit drug use is associated with severe health-related harms, yet people who use drugs (PWUD) face substantial barriers to healthcare. We sought to identify factors associated with disclosure of drug use to a healthcare provider and describe differences in self-reported quality of care received based on disclosure status.

METHODS

A client-reported experience questionnaire on healthcare access and quality, adapted from the World Health Organization Survey on Health and Health System Responsiveness, was administered within two ongoing prospective cohort studies of PWUD in Vancouver, Canada. Respondents not currently receiving addiction treatment were asked about experience of care and drug use disclosure to their most commonly accessed outpatient healthcare provider in the past 6 months. We used an adjusted logistic regression model to identify client characteristics associated with disclosure.

RESULTS

From a total of 261 respondents (34.1% female), less than half (n = 125, 47.8%) reported disclosing drug use to their healthcare provider. Indigenous participants were less likely to disclose compared to non-Indigenous participants (adjusted OR: 0.55, 95% confidence interval: 0.30, 0.97). Disclosure was associated with lower self-reported quality of care (overall rating: disclosed 8.2 vs. did not disclose 8.8, p = 0.04).

CONCLUSIONS

In a sample of PWUD accessing outpatient healthcare services, we observed low rates of drug use disclosure, particularly for Indigenous respondents, and reduced quality of care for those who disclosed. These findings highlight the need for culturally safe and non-stigmatizing care to address pervasive stereotyping in the healthcare system and improved screening for substance use disorder in outpatient healthcare services.

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.

South African service users' perceptions of patient-reported outcome and experience measures for adolescent substance use treatment: A qualitative study

INTRODUCTION AND AIMS

Patient-reported outcome measures (PROM) and experience measures (PREM) for substance use disorder (SUD) treatment exist for adults but have unknown relevance for adolescents. This study aimed to explore adolescents' perceptions of effective SUD treatment and possible barriers to completing PROMs and PREMs to guide efforts to adapt the South African Addiction Treatment Services Assessment (SAATSA) for adolescents.

DESIGN AND METHODS

Five focus groups were conducted with 38 adolescent service users recruited from residential and outpatient SUD treatment facilities in South Africa. Group discussions explored perceptions of treatment components necessary for desired SUD treatment outcomes, treatment experiences that support engagement in care, and perceptions of PROM and PREM completion.

RESULTS

Participants viewed treatment elements that enhance motivation for change, coping and emotional regulation; provide recreational alternatives to substance use; and improve family relationships and home environments as critical to positive treatment outcomes. They reflected that provider characteristics and developmentally and culturally appropriate services facilitated engagement in treatment. PROM and PREM completion seemed acceptable, with participants suggesting ways to enhance their appeal.

DISCUSSION AND CONCLUSION

Findings confirm that adult-oriented PROMs and PREMs require adaptation for adolescents. Service user inputs identified ways to expand the content of the SAATSA to better reflect adolescents' treatment priorities. These inputs have also guided changes to item formulation and administration procedures to enhance the SAATSA's acceptability for adolescents. Ensuring the SAATSA addresses treatment outcomes and experiences that matter to adolescents is vital for generating information to guide improvements to adolescent SUD services.
