Abstract

Introduction Substance use disorders are chronic conditions that require a multidimensional treatment approach. Despite ongoing efforts to diversify such treatments, evidence continues to illuminate modest rates of treatment engagement and perceived barriers to treatment. Patient-centred care (PCC) is one approach that may strengthen the responsiveness of treatments for people with problematic substance use. The aim of this scoping review is to explore how the principles of PCC have been implemented and operationalised in healthcare settings for people with problematic substance use.

Methods and analysis This scoping review follows the iterative stages of the Arksey and O’Malley framework. Both empirical (from Medline, Embase, PsycINFO, CINAHL and ISI Web of Science) and grey literature references will be considered if they focused on populations with problematic substance use and described or measured PCC or one of its principles in a health-oriented context. Two reviewers will independently screen references in two successive stages of title/abstract screening and then full-text screening for references meeting title/abstract criteria. A descriptive overview, tabular and/or graphical summaries, and a directed content analysis will be carried out on extracted data. This scoping review has been registered with Open Science Framework (https://osf.io/5swvd/).

Ethics and dissemination This review will systematically examine the extent and nature of existing evidence of PCC in addiction research and clinical practice. Such evidence will contribute to the operationalisation of PCC for people with problematic substance use. A multidisciplinary team has been gathered to represent the needs of people with problematic substance use, healthcare providers and decision-makers. The team’s knowledge users will be engaged throughout this review and will participate in dissemination activities (eg, workshops, presentations, publications, reports).

Strengths and limitations of this study

  • This is the first scoping review to systematically explore which principles of patient-centred care have been implemented and their operationalisation among people with problematic substance use.

  • A multidisciplinary team composed of drug policy advocates, healthcare providers, decision-makers and academics will lead this scoping review.

  • Both the population (people with problematic substance use) and concept of interest (patient-centred care) have been indexed using a variety of terms which poses a challenge to ensuring breadth of the search.

  • A comprehensive search strategy has been developed in consultation with a health sciences librarian to promote a sensitive scope of empirical and grey literature sources.

  • This iterative scoping review study has been registered with Open Science Framework to enhance its transparency (https://osf.io/5swvd/).

Introduction 

Alcohol, tobacco and illicit substance use continues to be a significant public health concern that accounts for 11.2% of the global burden of disease and 21.1% of all deaths.1 People with substance use disorders are at an increased risk of mortality and morbidity2 3; and some may be further affected by lost family and social support, criminal justice involvement and social marginalisation.4 However, not all people with problematic substance use follow the same trajectory. Instead, there are individual variations in the personal meaning of substance use, in the intensity and frequency of use, and its associated harms.4–6 This heterogeneity in substance use disorders contributes to the complexity of its treatment.

It is increasingly accepted that there is no ‘one size fits all’ treatment approach for problematic substance use and that a range of treatments are required to meet the diverse needs and preferences of this population.5 6 For example, effective pharmacological therapies are available to assist with the treatment of some, but not all, substance use disorders (eg, tobacco, alcohol, opioid dependence).7 Treatment may also include psychosocial interventions (eg, cognitive behavioural therapy, contingency management or strengths-based treatment) either in combination with pharmacological therapies or alone.8 9 Regardless of the treatment provided, the main goal is to engage clients in care, since treatment engagement is widely recognised as one of the most important predictors of substance use outcomes.10 11

As such, tremendous efforts have been made towards improving treatment engagement. Examples include diversified treatment settings that offer traditional residential and hospital-based programmes, specialised outpatient programmes and, more recently, integrated service models.7 12 To increase the rate of detection and treatment engagement, opportunities for screening and brief intervention have also been incorporated and expanded outside of specialised substance use treatment programmes.13 Various problem-to-services matching designs have also been developed to increase successful treatment engagement by strengthening alignment between client’s needs and services offered.14–17

In spite of these important developments, research continues to demonstrate quite mixed uptake of these practices,17 as well as varying rates of treatment engagement.7 12 Globally, it is estimated that one out of every six people in need of substance use treatment is able to receive it; and this does not imply receipt of evidence-based or human-rights-based treatments.18 Even when examining evidence-based treatments, such as opioid agonist treatment, recent systematic reviews suggest a wide range in the rate of treatment retention (eg, from 37% to 91% at 12-month follow-up).19 There is also a substantial body of qualitative research that has revealed several areas in which clients (and in some cases providers) have perceived challenges with engaging in treatment. A few examples include perceived provider misunderstanding of treatment goals,20 discrepancies between client and provider’s treatment goals,21 a lack of treatment responsiveness to client’s perceived needs,22 23 challenges with involving clients in treatment planning and delivery24 and perceived power imbalances, stigma and discrimination.25–27 This evidence suggests that there remains a need to explore how treatment processes can be designed to better respond to client’s unique needs, while also considering the diversity of treatments and settings required.

Patient-centred care (PCC) is one potential approach warranting further exploration. PCC is rooted in a philosophy that puts the person first. It aims to meet client’s unique needs and preferences, enhance their experiences with care and involve them in all elements of treatment planning and delivery.28 Some of its origins can be traced back to Carl Rogers’ client-centred therapy which emphasised unconditional positive regard, empathy and genuineness in the therapeutic process.29 Over the last two decades, as the concept of PCC has garnered increased attention across the health and social sciences,30 31 its operationalisation has expanded beyond the role of the therapeutic relationship. For example, in nursing, empirically based conceptual frameworks32–34 agree that PCC entails an approach to care that is holistic, individualised, respectful and empowering. In medicine, the proposed frameworks converge around similar, but slightly reframed dimensions. Here, emphasis is on a biopsychosocial perspective, seeing the ‘patient-as-person’, enhancing the therapeutic alliance, and sharing power and responsibility.35–40 Differences in the conceptual meaning of PCC across disciplines have resulted in varying operationalisations.

That the meaning of PCC is currently somewhat discipline-specific poses challenges to determining the relationship between PCC and treatment process and outcome indicators. For example, a recent meta-analysis showed mixed effects of PCC (defined as shared control or decisions and/or consultations focused on whole person) on improved quality of care, treatment satisfaction and health outcomes.41 It also found support for generally positive effects of PCC on consultation process measures (eg, communication about treatments, levels of empathy),41 suggesting that PCC might overcome some of the challenges clients have historically experienced engaging in substance use treatment.

Indeed, elements of PCC have been recommended or defined as part of some addiction treatment approaches.6 For example, principles of respect, empathy or empowerment are integral to some treatments (eg, motivational interviewing, strengths-based treatment). However, to our knowledge, it is not known to what extent each of the dimensions of PCC have been purposefully implemented or tested across the spectrum of treatment approaches for people with problematic substance use. Bringing this evidence together in a systematic scoping review has the potential to identify cross-setting, discipline and population dimensions of PCC that have been defined, implemented and empirically explored.

Objective

The present scoping review will systematically explore how the principles of PCC have been implemented and operationalised in healthcare settings for people with problematic substance use. Specifically, this review aims to examine the extent and nature of existing evidence of PCC in addiction research and clinical practice.

Methods and analysis

This scoping review methodology will apply the classic framework developed by Arksey and O’Malley,42 recent enhancements43–45 and best practices for conducting and reporting systematic reviews (ie, Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) for Protocols and Scoping Reviews (PRISMA-ScR; online supplementary 1).46 47 Accordingly, a reflexive and iterative approach will be maintained; particularly during the study screening and data extraction phases which may become more refined throughout the review. The protocol (and any potential revisions) has been registered through Open Science Framework (https://osf.io/5swvd/).48 DistillerSR software for systematic reviews49 will be used by both reviewers to support screening, extraction, monitoring and the synthesis of findings.

Supplementary data

Stage 1: Defining the research question

The research question was developed as a broad framing of the population (ie, people with problematic substance use), the concept (ie, PCC) and the context (ie, health-oriented settings) to be explored. Thus, this scoping review asks:

  1. Which PCC principles have been implemented in health-oriented settings for people with problematic substance use?

  2. How have these PCC principles been operationalised when used in health-oriented settings for people with problematic substance use?

  3. What outcomes from the implementation of PCC principles have been empirically measured or tested?

Stage 2: Identifying relevant literature

Our goal in developing this search strategy (online supplementary 2) is to undertake a comprehensive review of the existing evidence base. However, this particular research question poses a challenge to keyword selection due to the evolution of terms used to describe both the population and concept of interest. For instance, problematic substance use has grown from the pejorative language of the ‘addict’ to a health-oriented view of ‘substance dependent populations’ and now onto the more person-focused discourse of ‘people with problematic substance use’.50 51

Supplementary data

Likewise, as described above, conceptual frameworks of PCC have also varied, adding to the complexity of this search. To overcome this challenge, we have developed a search strategy informed by the most consistently identified and operationalised principles of PCC (in the above-mentioned frameworks), as well as keywords and MeSH terms from systematic reviews52 53 and empirical references54–56 previously conducted with our population of interest: (1) understanding the whole person to account for the biological, psychological and social aspects of patients’ illnesses; (2) exploring the disease and illness experience to understand the personal meaning of illness and treatment for the patient; (3) finding common ground where power, knowledge and responsibility are shared between the patient and provider; and (4) enhancing the patient-provider relationship to improve the positive outcomes of treatments provided. We have also engaged in an extensive consultation process with an experienced Health Science Librarian (at the University of British Columbia) as well as the knowledge users represented in our team (authors SM and SH). The search strategy will also be peer reviewed (ie, peer review of electronic search strategies) to promote its rigour and feasibility.57

Given our interest in undertaking a comprehensive review of existing research and clinical guidelines related to PCC in the addictions field, both empirical (primary studies, previous reviews) and grey literature documents (conference abstracts, reports and clinical guidelines) will be included in our search. The search for empirical sources will be conducted in the most important electronic databases for the medical and social sciences: Medline (Ovid), Embase (Ovid), PsycINFO, CINAHL and ISI Web of Science. The search strategy has been developed in Medline (Ovid) (online supplementary 2) and will be adapted to the other databases. The search strategy will include subject headings, related terms and keywords as necessary for the research question. Boolean logic and operators (ie, ‘and’, ‘or’, ‘not’) will be used to combine and refine search terms and concepts.

For the grey literature search strategy, we will use recommended resources58 and consult with the Health Sciences Librarian and our team’s knowledge users to devise a database specific approach. The search for abstracts, reports and clinical guidelines will be carried out in several Canadian-specific databases: British Columbia Guidelines and Protocols Databases, CPG Infobase, the Registered Nurses’ Association Clinical Practice Guidelines Program and Des Libris. For international grey literature documents, we will search National Guideline Clearinghouse, TRIP, Google and Google Scholar databases.

Stage 3: Study selection

A two-stage collaborative review process will be used to select references. Eligibility criteria have been developed a priori, in consultation with the study team. The screening form will be piloted on the first 20 citations of the initial Medline (Ovid) search to test both the criteria and reviewer agreement. Two independent reviewers (authors KM and SB) will apply eligibility criteria during the initial title/abstract review. After each review stage, the reviewer’s agreement will be assessed and a third reviewer (author EO-J) will be consulted in cases of disagreement, until consensus is achieved.

A title/abstract (or executive summary for reports and guidelines) will be eligible for full text screening if it:

  1. Refers to people with problematic substance use (including tobacco, alcohol, cannabis, stimulant, opioid use or dual diagnoses).

  2. Is about delivering PCC or one of its principles (including care that understands the whole person; explores the disease and illness experience; finds common ground and enhances the patient–provider relationship).

  3. Is set in a health-oriented context (including inpatient or outpatient hospital settings, emergency departments, community-based or primary care health settings, and any specialised drug treatment or low-threshold agencies and programmes; excluding prison-based health programmes and self-help models such as narcotics or alcoholics anonymous).

  4. Was published between 1 January 1960 and 1 July 2018 in English, French, Spanish, Italian, Portuguese or German.

Full text empirical articles, reports and guidelines will then be obtained for titles/abstracts meeting these above criteria and will undergo further screening. In addition to the title/abstract criteria, full texts  will be included if:

  1. It provided an operational definition of the PCC framework that was delivered to people with problematic substance use in the health-oriented context.

  2. It observed at least one patient outcome (eg, treatment engagement, substance use behaviours, treatment satisfaction) and/or treatment process outcome (eg, provider communication skills) of the PCC approach (this criterion pertains to empirical articles only).

As such, articles that provide only a recommendation to adopt PCC or an opinion of how PCC should be implemented in health-oriented settings for people with problematic substance use will not be included.

Stage 4: Data extraction

Results of the search will be collated in DistillerSR,49 allowing the research team to deduplicate and perform data extraction. We will follow recommended data charting methods42 47 to systematically capture relevant details for studies/reports and guidelines (table 1). Data charting forms will be piloted with the first five empirical and grey literature references and may be adapted thereafter (with input from the teams’ knowledge users).

Table 1

Data extraction and charting for empirical and grey literature sources

Stage 5: Collating, summarising and reporting the results

We will present a descriptive overview (including tabular and/or graphical summaries) of the eligible full texts.42 We will also summarise studies by each broader category of substances primarily used (ie, tobacco, cannabis, alcohol, opioid, stimulant, dual diagnosis). Displaying information in this way will highlight population-specific similarities and differences in PCC, its definition and outcomes. This will facilitate the identification of future directions for research and practice. All tables and charts will include narrative summaries, relating the findings to the review’s research question. Additionally, we will develop a final report of the review47 according to PRISMA-ScR guidelines.46

Given that one aim of this review is to understand how PCC has been defined and implemented in healthcare services for people with problematic substance use, a directed content analysis will be carried out on included guidelines. This approach has been deemed most suitable to the present review, since it allows existing theory to guide the coding and analysis (in our case, principles of PCC defined a priori), while still allowing new evidence to emerge.59 Specifically, we are interested in qualitatively analysing the definition of PCC adopted in the guidelines, how it was developed, which healthcare providers were involved, and any outcomes or ongoing evaluations of the programme. To do so, data from the guidelines will be imported to MAXQDA V.12,60 a qualitative analysis software program that supports a multiuser approach. This analysis will be conducted by authors KM, SB and EO-J, who have prior experience conducting thematic analysis on similar topics.61 62 As is common in directed content qualitative analysis,59 a coding framework will be developed a priori and will then be applied by authors KM and SB independently. Results from this analysis will be summarised and—where relevant—numerical summaries may also be used to provide additional context to the themes (eg, number of clients treated, number of staff).

Stage 6: Consultation process and engagement of knowledge users

The ultimate aim of this review is to generate evidence that can be used to inform decision-makers and healthcare providers on the feasibility, implications and potential outcomes associated with PCC for substance use treatment. To achieve this goal, we have engaged a multidisciplinary team of knowledge users who represent the needs of: people with problematic substance use, healthcare providers and decision-makers. Consulting with the teams’ healthcare providers and decision-makers (authors SH, SM and DCM) will promote a methodology that reflects the realities of patient-provider roles and the healthcare system’s organisation. Also, our team’s drug policy knowledge user (author JW) represents a national organisation of people who use drugs and this critical perspective will ensure that all aspects of this review are rooted in the client-centred needs of this diverse population. The specific contributions of the knowledge users to each stage of this review have been defined throughout. At this time, knowledge users have reviewed early drafts of the search strategy, identifying additional terms that are important for inclusion given the population, concept and contexts of interest (eg, trauma-informed care and culturally-safe care). Knowledge users have also provided several grey-literature references (clinical guidelines and reports) to be considered for inclusion. As the project continues to evolve, all knowledge users will be involved in supporting the interpretation of findings and their dissemination.

Patient and public involvement

This scoping review protocol has engaged the expertise of a national organisation of people who use(d) drugs through the involvement of this organisations’ president. This knowledge user (author JW) has made contributions to the development of the research question and will also be extensively involved during the interpretation and dissemination phases of this project.

Ethics and dissemination

As substance use disorders are increasingly recognised as a chronic condition often marked by cycles of relapse and recovery, the public healthcare system is considering how existing treatment and intervention approaches can be optimised to meet the long-term and evolving goals of clients.18 Adopting patient-centred or person-centred approaches may increase the responsiveness of existing treatments to individual client needs, expectations and preferences. To our knowledge, this review will be the first to systematically examine the extent and nature of existing evidence of PCC in addiction research and clinical practice.

Our dissemination strategy will use traditional approaches, including open-access peer-reviewed publication(s), scientific presentations and a report. Additionally, we are committed to promoting further action based on the potential findings of this review. Therefore, we will host a half-day round-table meeting—bringing together people with problematic substance use, healthcare providers (from diverse settings) and decision-makers to brainstorm potential opportunities for future areas of research and clinical practice work. For example, we may engage in a concept mapping exercise, using the findings of this review to integrate stakeholders’ knowledge, interpretations and priorities into practice. The multidisciplinary nature of this team will facilitate and support our goal of bringing together these different representatives together.
