Factors associated with change in moderate or severe symptoms of anxiety and depression in community-living adults and older adults during the COVID-19 pandemic

OBJECTIVES

Few are the longitudinal studies on the changes in moderate or severe symptoms of anxiety or depression (MSS-ANXDEP) from before to during the COVID-19 pandemic in Canada. The aim was to study the change in MSS-ANXDEP and associated sociodemographic, economic, psychosocial, health behaviour and lifestyle, and clinical factors.

METHODS

The current sample includes 59,997 adults aged ≥ 35 years participating in the 2018 and 2020 health surveys of the 5 established cohorts of the Canadian Partnership for Tomorrow's Health (CanPath). MSS-ANXDEP was based on a cutoff score ≥ 10 on the 7-item Generalized Anxiety Disorder Scale and Patient Health Questionnaire (PHQ-8). Change in MSS-ANXDEP was categorized as follows: no MSS-ANXDEP, remitted, incident, and persistent. Multinomial regressions were used to study MSS-ANXDEP as a function of sociodemographic, economic, psychosocial, health behaviours and lifestyle, and clinical factors.

RESULTS

Sociodemographic and economic (i.e. age, gender, cohort, race/ethnicity, lower income, decreased in income, work status, being an essential worker), lifestyle and health behaviours (i.e. smoking, cannabis and alcohol use, drinking more alcohol), psychosocial (i.e. provide help to others, information and instrumental support, and change in relationships with friends, family, and partner) and clinical factors (i.e. lifetime mental disorder and multimorbidity) were associated with remitted, incident, and persistent MSS-ANXDEP.

CONCLUSION

Health and socio-economic factors were associated with changes in symptoms of anxiety and depression during the pandemic, further increasing inequities in mental health needs. Public health campaigns on the importance of healthy behaviours should continue and health policies should reduce economic and social barriers to integrated substance use and mental health care.

Care trajectories of individuals with anxiety disorders: A retrospective cohort study

BACKGROUND

Anxiety disorders (ADs) are associated with increased healthcare use (HCU), and individuals may seek healthcare through various pathways according to clinical and individual characteristics. This study aimed to characterize care trajectories (CTs) of individuals with ADs.

METHODS

This is a retrospective cohort study using the Care Trajectories - Enriched Data cohort, a linkage between the Canadian Community Health Surveys (CCHS), and health administrative data from Quebec. The cohort included 5143 respondents reporting ADs to the CCHS between 2009 and 2016. We measured CTs over 5 years before CCHS using a state sequence analysis.

RESULTS

The cohort was categorized into five types of CTs. Type 1 (52.7 %) was the lowest care-seeking group, with fewer comorbidities. Type 2 (24.0 %) had higher levels of physical and mental health comorbidities and moderate HCU, mainly ambulatory visits to general practitioners. Type 3 (13.1 %) represented older patients with the highest level of physical illnesses and high HCU, predominantly ambulatory consultation of specialists other than psychiatrists. Types 4 and 5 combined young and middle-aged patients suffering from severe psychological distress. HCU of type 4 (6.7 %) was high, mainly consultations of ambulatory psychiatrists, and HCU of type 5 (3.5 %), was the highest and mostly in acute care.

LIMITATIONS

Administrative and survey data may have coding errors, missing data and self-report biases.

CONCLUSION

Five types of CTs showed distinct patterns of HCU often modulated by physical and mental health comorbidities, which emphasizes the importance of considering ADs when individuals seek care for other mental health conditions or physical illness.

Factors associated with mental health service use during the pandemic: Initiation and barriers

BACKGROUND

Scarce are the studies focusing on initiation of new mental health service use (MHSU) and distinguishing individuals who have sought services but have been unsuccessful in accessing these.

AIMS

Assessing the factors associated with initiating new MHSU as compared to no MHSU due to self-reported no need, no MHSU due to health system and personal barriers and MHSU using resources already in place.

METHODS

The sample included participants (n = 16,435) in the five established regional cohorts of the Canadian Partnership for Tomorrow's Health (CanPath) who responded to the CanPath COVID-19 health surveys (May-December 2020 and January-June 2021). Multinomial regression analyses were carried out to study MHSU since the pandemic (March 2020) as a function of predisposing, enabling and need factors. Analyses were carried out in the overall sample and restricted to those with moderate and severe symptoms (MSS) of depression and/or anxiety (n = 2,237).

RESULTS

In individuals with MSS of depression and/or anxiety, 14.4% reported initiating new MHSU, 22.0% had no MHSU due to barriers and personal reasons and 36.7% had no MHSU due to self-reported no need. Age, living alone, lower income, a decrease in income during the pandemic and health professional status were associated with MHSU. Younger adults were more likely to initiate MHSU during the pandemic than older adults who reported not being comfortable to seek mental health care or self-reported no need. Individuals living alone and with lower income were more likely to report not being able to find an appointment for mental health care.

CONCLUSIONS

Awareness campaigns focusing on older adults that explain the importance of seeking treatment is needed, as well as sensitising health professionals as to the importance of informing and aiding individuals at risk of social isolation and lower socio-economic status as to available mental health resources and facilitating access to care.

Demand management processes to improve access to cognitive-behavioral therapies for anxiety disorders: a grounded theory study

Introduction

Anxiety disorders are impactful mental health conditions for which evidence-based treatments are available, notably cognitive-behavioral therapies (CBTs). Even when CBTs are available, demand-side factors limit their access, and actors in a position to perform demand management activities lack a framework to identify context-appropriate actions.

Methods

We conducted a constructivist grounded theory study in Quebec, Canada, to model demand management targets to improve access to CBTs for anxiety disorders. We recruited key informants with diverse experiences using purposeful, then theoretical sampling. We analyzed data from 18 semi-directed interviews and 20 documents through an iterative coding process centered around constant comparison.

Results

The resulting model illustrates how actors can target clinical-administrative processes fulfilling the demand management functions of detection, evaluation, preparation, and referral to help patients progress on the path of access to CBTs.

Discussion

Modeling clinical-administrative processes is a promising approach to facilitate leveraging the competency of actors involved in demand management at the local level to benefit public mental health.

The effectiveness of transdiagnostic cognitive behavioural therapy for anxiety disorders: the role of and impact of comorbid depression

Transdiagnostic Cognitive Behaviour Therapy (tCBT), an intervention designed to be applicable across multiple diagnoses, was introduced to improve limitations in traditional therapy such as cost and access to trained therapists. It has been established as an effective and efficacious treatment for anxiety disorders, though there has been little research focussed on the role of depression. The current study investigated the role of comorbid depression during tCBT for anxiety disorders in primary care settings as an outcome and a moderator of anxiety outcomes. Results of multi-level ANOVAs indicated no significant difference in anxiety outcomes regardless of whether there was a comorbid depression diagnosis in the tCBT condition, and that individuals with a comorbid depression diagnosis experienced significantly greater reduction in anxiety severity than those without. Depression symptom severity decreased to a significantly greater extent in the tCBT condition than in TAU when the outcome measure of Patient Health Questionnaire was utilised as the outcome measure, but this was not mirrored when the Clinician Severity Rating was utilised as the outcome measure. This study provides preliminary support for the effectiveness of Transdiagnostic Cognitive Behaviour therapy for those with both a principal anxiety disorder and comorbid depression in symptom reduction.

Cost-Effectiveness of Group Transdiagnostic Cognitive Behavioural Therapy for Anxiety Disorders in Primary Care Settings: Economic Evaluation From the Healthcare System Perspective Over a 1-Year Time Horizon

AIM

To assess the incremental cost-effectiveness ratio (ICER) of group transdiagnostic cognitive-behavioural therapy (tCBT) added to treatment as usual (TAU) for anxiety disorders compared to TAU only from the healthcare system perspective over a 1-year time horizon.

METHODS

Data from a pragmatic multisite randomized controlled trial where adults (18-65 years) with an anxiety disorder were randomized to tCBT + TAU (n = 117) or TAU (n = 114). Group tCBT is a 12-week (2h weekly sessions) community-based intervention. Health service utilization and related costs were captured from medico-administrative data and included those for the intervention, ambulatory visits, hospitalizations and medications. Effectiveness was based on quality-adjusted life years (QALYs). The study included measures at baseline, 4, 8, and 12 months. Intention-to-treat and complete case analyses were carried out. Missing data were imputed using multiple imputation analyses. Seemingly unrelated regression analyses were used to assess the effect of the intervention on total costs and QALYs while also adjusting for baseline confounders. The probability of cost-effectiveness of the intervention was assessed according to different willingness-to-pay (WTP) thresholds using the net benefit regression method.

RESULTS

The ICER of tCBT + TAU as compared to TAU in the intention-to-treat analysis was $6,581/QALY. Complete case analyses showed a similar ICER of $6,642/QALY. The probability at a WTP threshold of $20,000 and $40,000 that tCBT + TAU as compared to TAU is cost-effective is 93.0% and 99.9%.

CONCLUSION

tCBT added to TAU appears to be cost-effective from the healthcare system perspective for treating adult patients with anxiety disorders. Larger trials including young and older adults as well as a range of anxiety disorders are needed to further investigate the cost-effectiveness of tCBT in different patient populations.

Moderators of the cost-effectiveness of transdiagnostic CBT for anxiety disorders over an 8-month time horizon using a net-benefit regression framework

BACKGROUND

Access to evidence-based psychological treatment is a concern in many parts of the globe due to government-level financial constraints and patient-level barriers. Transdiagnostic cognitive behavioural therapy (tCBT) is an effective treatment approach that uses a single protocol for anxiety disorders which could enhance the dissemination of evidence-based psychotherapy. In a context of limited resources, the study of treatment moderators can allow to identify subgroups for which the cost-effectiveness of an intervention differs, information that could impact decision-making. So far, there has been no economic evaluation of tCBT for different subpopulations. The objectives of this study, using the net-benefit regression framework, were to explore clinical and sociodemographic factors as potential moderators of the cost-effectiveness of tCBT compared to treatment-as-usual (TAU).

METHODS

This is a secondary data analysis of a pragmatic randomized controlled trial opposing tCBT added to TAU (n = 117) to TAU only (n = 114). Data on costs from the health system and the limited societal perspectives, as well as anxiety-free days, an effectiveness measure based on the Beck Anxiety Inventory, were collected over an 8-month time horizon and used to derive individual net-benefits. The net-benefit regression framework was used to assess moderators of the cost-effectiveness of tCBT + TAU as opposed to TAU alone. Variables of sociodemographic and clinical nature were assessed.

RESULTS

Results showed that the number of comorbid anxiety disorders significantly moderated the cost-effectiveness of tCBT + TAU compared to TAU from the limited societal perspective.

CONCLUSIONS

The number of comorbid anxiety disorders was identified as a moderator affecting the cost-effectiveness of tCBT + TAU compared to TAU from the limited societal perspective. More research is needed to strengthen the case of tCBT from an economic standpoint for large-scale dissemination.

Mental health service use and associated predisposing, enabling and need factors in community living adults and older adults across Canada

OBJECTIVES

Using Andersen's model of health care seeking behavior, we examined the predisposing, enabling, and need factors associated with mental health service use (MHSU) during the first wave of the COVID-19 pandemic across Canada.

METHODS

The sample included n = 45,542 participants in the 5 established regional cohorts of the Canadian Partnership for Tomorrow's Health (CanPath) and who responded to the CanPath COVID-19 health survey (May-December 2020), with complete data on MHSU. Multivariable logistic regression analyses were carried out to study MHSU as a function of predisposing, enabling, and need factors. Analyses were stratified by regional cohort.

RESULTS

Among the need factors, individuals reporting moderate/severe symptoms of depression and anxiety and poorer self-rated mental health were more likely to report MHSU. Among the enabling factors, receipt of informational/financial/practical support was associated with increased MHSU. While income was not consistently associated with MHSU, reported decrease in income was marginally associated with reduced MHSU. Among the predisposing factors, identifying as female or other gender minority was associated with increased MHSU, as was the presence of past-year cannabis use. In contrast, older age and alcohol consumption were associated with reduced MHSU.

CONCLUSION

Need factors were consistently associated with MHSU. Although income inequities in MHSU were not observed, changes such as reduced income during the pandemic may lead to barriers in accessing mental health services. Future research should focus on better identifying contextual enabling factors and policies that overcome financial barriers to MHSU.

An analysis of differential improvement by diagnosis in group transdiagnostic cognitive behaviour therapy for anxiety disorders

INTRODUCTION

Anxiety disorders are the most prevalent among the mental health disorders and have a negative impact on an individual's life. Cognitive behaviour therapy (CBT) is documented as the most effective treatment for anxiety disorders. However, challenges associated with implementing diagnosis-specific CBT have led to transdiagnostic approaches of CBT (tCBT). tCBT uses a single protocol with core elements of CBT for treatment of anxiety disorders broadly. The aim of the current study is to examine whether participants with different principal anxiety diagnoses demonstrate similar anxiety reduction.

METHODS

The current study involved a secondary analysis of 117 participants randomly allocated to receive tCBT for anxiety disorders in a pragmatic randomised effectiveness trial. Beck Anxiety Inventory (BAI) and Clinician Severity Ratings (CSR) scales were administered at pre- and post-treatment and one-year follow-up, while the Anxiety Disorder Diagnostic Questionnaire - Weekly (ADDQ-W) was administered each session.

RESULTS

Mixed-factorial analyses of variance (ANOVAs) indicated that participants with GAD, SAD and PD/A improved to post-treatment and maintained to follow-up, with no differential improvement across principal diagnoses. Mixed effect regression modelling of session by session measures indicated non-differential negative slopes across principal diagnoses of GAD, SAD and PD/A.

CONCLUSION

Overall, results indicate that group tCBT for anxiety disorders shows equal effectiveness for GAD, PD/A, and SAD in real-world conditions.

Experience of LGBTQIA2S+ populations with gambling during the COVID-19 pandemic: protocol for a mixed-methods study

INTRODUCTION

Research undertaken since the beginning of the COVID-19 pandemic has provided us information about the impact of the pandemic on the gambling habits of the general population. However, very little is known about certain subgroups at increased risk of developing gambling disorder, such as the LGBTQIA2S+ population. The purpose of this study is to describe the impact of the COVID-19 pandemic on gambling behaviours among LGBTQIA2S+ individuals. In addition, we want to understand the experiences of the LGBTQIA2S+ population with gambling disorder and identify interventions that LGBTQIA2S+ people have found to be effective in addressing problem gambling during the COVID-19 pandemic.

METHODS AND ANALYSIS

This study has a sequential explanatory mixed-method design in two phases over 2 years. The first phase is a correlational study. We will conduct a cross-sectional survey using a stratified random sampling among Canadian residents who are 18 years of age or older, self-identify as sexually and gender-diverse (ie, LGBTQIA2S+) and have gambled at least once in the previous 12 months. This survey will be administered online via a web panel (n=1500). The second phase is a qualitative study. Semistructured interviews will be conducted with LGBTQIA2S+ people with problematic gambling (n=30).

ETHICS AND DISSEMINATION

This research project has been ethically and scientifically approved by the Research Ethics Committee and by the CIUSSS de l'Estrie-CHUS scientific evaluation committee on 3 March 2022 (reference number: 2022-4633-LGBTQ-JHA). Electronic and/or written informed consent, depending on the data collection format (online survey and online or in-person interviews), will be obtained from each participant. A copy of the consent form and contact information will be delivered to each participant.

Cost-effectiveness of transdiagnostic group cognitive behavioural therapy for anxiety disorders v. treatment as usual: economic evaluation of a pragmatic randomized controlled trial over an 8-month time horizon using self-reported data

BACKGROUND

This economic evaluation supplements a pragmatic randomized controlled trial conducted in community care settings, which showed superior improvement in the symptoms of adults with anxiety disorders who received 12 sessions of transdiagnostic cognitive-behavioural group therapy in addition to treatment as usual (tCBT + TAU) compared to TAU alone.

METHODS

This study evaluates the cost-utility and cost-effectiveness of tCBT + TAU over an 8-month time horizon. For the reference case, quality-adjusted life years (QALYs) obtained using the EQ-5D-5L, and the health system perspective were chosen. Alternatively, anxiety-free days (AFDs), derived from the Beck Anxiety Inventory, and the limited societal perspective were considered. Unadjusted incremental cost-effectiveness/utility ratios were calculated. Net-benefit regressions were done for a willingness-to-pay (WTP) thresholds range to build cost-effectiveness acceptability curves (CEAC). Sensitivity analyses were included.

RESULTS

Compared to TAU (n = 114), tCBT + TAU (n = 117) generated additional QALYs, AFDs, and higher mental health care costs from the health system perspective. From the health system and the limited societal perspectives, at a WTP of Can$ 50 000/QALY, the CEACs showed that the probability of tCBT + TAU v. TAU being cost-effective was 97 and 89%. Promising cost-effectiveness results using AFDs are also presented. The participation of therapists from the public health sector could increase cost-effectiveness.

CONCLUSIONS

From the limited societal and health system perspectives, this first economic evaluation of tCBT shows favourable cost-effectiveness results at a WTP threshold of Can$ 50 000/QALY. Future research is needed to replicate findings in longer follow-up studies and different health system contexts to better inform decision-makers for a full-scale implementation.

[Short-term interventions offered by les centres locaux de services communautaires (CLSC) to people living with anxiety or depressive disorders: Results of the longitudinal component of the Shared Knowledge study]

Context In Quebec, adult mental health (AMH) first-line teams are mandated to provide psychosocial services to people living with mental health difficulties, including anxiety and mood disorders. Following the establishment of new clinical guidelines in 2017, the duration of interventions was not to exceed 15 sessions, with some exceptions. Objectives The overall aim of the longitudinal component of the Shared Knowledge study was to evaluate the care experience of individuals with an anxiety or depressive disorder receiving a short-term intervention (<15 sessions) by first-line AMH teams, and the evolution of recovery over time. Specifically, the objectives were to: 1) determine the appreciation of short-term interventions by service users; and 2) assess the evolution over time of the symptomatology, functioning and quality of life and recovery of individuals receiving short-term interventions. Method A mixed method longitudinal design was used. Telephone interviews were conducted with participants, in which the following variables were quantitatively and qualitatively assessed: appreciation of services received, quality of relationship with the provider (INSPIRE), depressive symptoms (PHQ-9), anxiety symptoms (GAD-7), global functioning (WHODAS), quality of life (ReQOL), and personal recovery (ERTAD). Linear mixed model analyses were performed to examine changes over time on quantitative measures. Content analysis was performed on the qualitative data. Results A total of 63 individuals participated in an interview before the start of their intervention and 22 of them participated after the end of this intervention. Statistical analyses showed a significant improvement in anxiety symptoms, quality of life, and personal recovery, but no difference was observed in depressive symptoms and level of functioning. Nearly half (47.4%) of participants reported that the intervention they received had "completely" met the need that had led them to seek help, and 33.3% felt "completely" equipped or empowered in their recovery. The quality of the relationship with the caregiver, the opportunity to take part in decision-making, and the personalization of the intervention according to their needs and preferences were some of the elements that were particularly appreciated. Conclusion Short-term interventions seem to be appreciated and produce positive effects in many people suffering from anxiety or depressive disorders. However, they remain insufficient for a number of them. A personal recovery measure should be used in conjunction with symptomatology and functioning scales to monitor the progress of people using first-line mental health services.

Mindfulness-based stress reduction to improve depression, pain and high patient global assessment in controlled rheumatoid arthritis

Objective

The aim was to improve distressing patient-reported outcomes (PROs) that persisted in RA patients with clinically controlled inflammation (controlled RA).

Methods

In a pragmatic pilot study, we offered mindfulness-based stress reduction (MBSR), a group intervention, to controlled RA patients who had high (≥16) Centre for Evaluation Studies depression (CES-D) scores and/or patient general assessment of disease activity (PGA) at least 2/10 larger than evaluator general assessment (EGA) (PGA-EGA: Delta). Evaluations before, 6 and 12 months after MBSR included CES-D, PGA, modified HAQ, simple disease activity index (SDAI), anxiety (general anxiety disorder 7; GAD-7), coping strategies (coping with health injuries and problems; CHIP), sleep disturbance and pain. Facilitators and obstacles to recruitment and participation were identified. A subset of patients was interviewed for qualitative analysis of their experience.

Results

Out of 306 screened patients, 65 were referred, 39 (60%) agreed and 28 (43%) completed MBSR. Anticipated burden, timing and frequency of group meetings, commuting issues, age extremes and co-morbidities were barriers to participation. Up to 12 months after MBSR, anxiety, depression, emotion-oriented coping, sleep and function significantly improved. Nonetheless, no significant impact was observed on pain, PGA, Delta or SDAI. The interviews revealed that benefits, including integration of effective coping strategies, were maintained.

Conclusion

We addressed MBSR feasibility issues and selection of outcomes in controlled RA patients with distressing PROs. For patients who chose to participate in MBSR, lasting benefits were evident for anxiety, depression, sleep and function. Larger studies are required to evaluate the weaker impact of MBSR on RA-related pain and PGA.

Minimally Adequate Treatment for Depression and Anxiety Associated With Mortality in Primary Care Older Adults

OBJECTIVE

To assess the association between receipt of minimally adequate treatment (MAT) and mortality in a sample of community primary care older adults with depression and anxiety.

METHOD

The present study was conducted among a sample of 358 older adults ( ≥ 65 years old) with depression or an anxiety disorder recruited in primary care practices between 2011 and 2013. Participants agreed to link their health survey and administrative data for the 3 years preceding and following the baseline interview. Depression and anxiety disorders were based on self-reported symptoms aligned with DSM-5 criteria and physician diagnoses (International Classification of Diseases [ICD], 9^th and 10^th revisions). MAT was defined according to Canadian guidelines and include receipt of pharmacotherapy and ≥ 4 medical visits within 3 months or a number of psychotherapy sessions (individual, group, or family) over 12 months (depression: ≥8; anxiety disorders: ≥5 to 7). All-cause 3-year mortality was ascertained from the vital statistics death registry in Québec. Propensity score weighted regression analysis was conducted to assess the association between receipt of MAT and mortality adjusting for individual, clinical, and health system study factors.

RESULTS

Receipt of MAT was associated with a reduced risk of mortality (hazard ratio [HR]: 0.27; 95% confidence interval [95% CI], 0.12 to 0.62). Individual and clinical factors associated with increased mortality included older age, male sex, being single, low functional status, and increased physical disorders and cognitive functioning. Lifestyle factors associated with reduced and increased mortality included alcohol consumption and smoking, respectively. Health system factors such as perceived adequate number of visits to speak to the doctor about emotional problems and continuity of care were associated with reduced mortality.

CONCLUSION

The current study highlights the important role of primary care physicians in detecting and providing MAT for older adults with depression and anxiety, as this may have an effect on longevity.

French adaptation and validation of the Panic Disorder Severity Scale-self-report

BACKGROUND

The aims of this study were to conduct a cross-cultural validation of the Panic Disorder Severity Scale - Self-Report (PDSS-SR) and to examine psychometric properties of the French-Canadian version.

METHODS

A sample of 256 adults were included in the validation study based on data from the baseline interview of a clinical trial on transdiagnostic cognitive-behavioral therapy for mixed anxiety disorders. Participants completed the Anxiety and Related Disorders Interview Schedule (ADIS-5), and self-report instruments including the PDSS-SR, Beck Anxiety Inventory (BAI), Mobility Inventory for Agoraphobia (MIA), Sheehan Disability Scale (SDS), Patient Health Questionnaire (PHQ-9), Social Phobia Inventory (SPIN), Insomnia Severity Index (ISI) and Penn State Worry Questionnaire (PSWQ). The cross-cultural adaptation in French of the PDSS-SR included a rigorous back-translation process, with an expert committee review. Sensitivity to change was also examined with a subgroup of patients (n = 72) enrolled in the trial.

RESULTS

The French version of the PDSS-SR demonstrated good psychometric properties. The exploratory factor analysis supported a one factor structure with an eigenvalue > 1 that explained 64.9% of the total variability. The confirmatory factor analysis (CFA) corroborated a one-factor model with a good model fit. Internal consistency analysis showed a .91 Cronbach's alpha. The convergent validity was adequate with the ADIS-5 clinical severity ratings for panic disorder (r = .56) and agoraphobia (r = .39), as well as for self-report instruments [BAI (r = .63), MIA (accompanied: r = .50; alone: r = .47) and SDS (r = .37)]. With respect to discriminant validity, lower correlations were found with the SPIN (r = .17), PSWQ (r = .11), ISI (r = .19) and PHQ-9 (r = .28). The optimal threshold for probable diagnosis was 9 for the PDSS-SR and 4 for the very brief 2-item version. The French version showed good sensitivity to change.

CONCLUSIONS

The French version of the PDSS-SR has psychometric properties consistent with the original version and constitutes a valid brief scale to assess the severity of panic disorder and change in severity over time, both in research and clinical practice.

Transdiagnostic cognitive-behavioral group therapy for anxiety disorders: Therapists’ perception of group management in community-based care

Introduction

Cognitive-behavioral therapy (CBT) is recognized as an effective treatment for anxiety disorders. Transdiagnostic group CBT (tCBT) targets cognitive and behavioural intervention strategies common to anxiety disorders. tCBT allows the treatment of a larger number of patients simultaneously and therapists only need to master a single intervention protocol. However, tCBT may present several challenges for therapists, particularly regarding group management.

Objectives

To explore therapists’ perceptions and experience of group management during tCBT for mixed anxiety disorders.

Methods

A qualitative study embedded in a randomized controlled trial of group tCBT (Roberge & Provencher; CIHR, 2015-2021). Semi-structured interviews were conducted with 18 of the 21 therapists to document their perceptions and to identify improvements for tCBT delivery. The data were analyzed using a deductive approach and based on the interactive cyclical process of data reduction, display and conclusion drawing.

Results

Therapists raised the challenge of the heterogeneous characteristics of participants’ anxious profile, since they had to be creative to provide exercises that were suitable for a whole group. Exposure exercises, a key component of tCBT, were particularly affected by the composition of the groups. Previous group animation experience and the ability to establish a therapeutic alliance from a group perspective were important facilitators. Co-therapy also facilitated the intervention, since it allowed the therapists to be more vigilant to group dynamics and favored the organization of tCBT.

Conclusions

This study highlights the importance of exploring therapists’ perceptions and experience about group management in order to identify facilitators and barriers of group tCBT in community-based care.

Panic Disorder Severity Scale self-report: transcultural validation and sensitivity to change of the French-Canadian adaptation

Introduction

The self-report version of the Panic Disorder Severity Scale (PDSS-SR) is a reliable and valid instrument to assess panic disorder, but is unavailable in French.

Objectives

The aim of this study was to conduct a transcultural validation of the French-Canadian PDSS-SR and examine its psychometric properties.

Methods

This study is part of a pragmatic RCT of group transdiagnostic CBT for anxiety disorders, and includes 272 adults meeting DSM-5 panic disorder diagnostic criteria. At baseline, participants completed the Anxiety and Related Disorders Interview Schedule (ADIS-5), the French-Canadian PDSS-SR and self-report measures. Convergent validity was assessed with Spearman correlations, Cronbach’s α was used to analyse internal consistency, and confirmatory factor analysis (CFA) evaluated its factor structure. Sensitivity to change was assessed with paired sample t-tests in patients (n = 72) meeting DSM-5 criteria for panic disorder at baseline with posttreatment data.

Results

108 patients met DSM-5 criteria for panic disorder, including 58 with agoraphobia. The majority were women (85.3%) and mean age was 37.1 (SD = 12.4). Internal consistency (Cronbach’s α) was 0.91. For convergent validity, the highest correlation was with the Beck Anxiety Inventory (r = 0.64). CFA suggested a two-factor model. Optimal threshold for probable diagnosis was 10. Analyses support sensitivity to change when comparing transdiagnostic group CBT and control conditions.

Conclusions

With its good psychometric properties in primary care patients, the French-Canadian self-report version of the Panic Disorder Severity Scale is an efficient and practical instrument for both clinicians and researchers working in the field of mental health.

Which, who and when? Therapeutic processes in group cognitive behaviour therapy for anxiety disorders

The evidence for the effect of therapeutic alliance in group cognitive behaviour therapy (CBT) for anxiety disorders is unclear. Identifying whether the alliance-outcome relationship depends on (1) which components are assessed, (2) who is measuring the alliance and (3) when the alliance is measured will help to clarify the role of the client-therapist relationship in therapy. The present study explored the effects of alliance component (agreement vs. bond), rater perspective (client vs. therapist) and timing (early vs. late therapy) on the alliance-outcome relationship. Individuals with an anxiety disorder enrolled into transdiagnostic group CBT were studied, with n = 78 at early therapy and n = 57 at late therapy. Results showed that greater client-rated agreement significantly predicted improved post-treatment outcomes throughout the course of therapy, while stronger client-rated bond in late therapy predicted reduced treatment gains. In contrast, therapist perceptions of agreement and bond were not associated with post-treatment outcomes at any point in therapy. Client-reported group cohesion also was not associated with additional variance in outcome after accounting for client-rated alliance. Overall, the findings highlight the importance of prioritizing the client's perception of the client-therapist relationship in CBT for anxiety disorders, as well as distinguishing the effects of component, rater and timing in future process-outcome studies.

Strategies to improve access to cognitive behavioral therapies for anxiety disorders: A scoping review

Background

Strategies to improve access to evidence-based psychological treatments (EBPTs) include but are not limited to implementation strategies. No currently available framework accounts for the full scope of strategies available to allow stakeholders to improve access to EBPTs. Anxiety disorders are common and impactful mental conditions for which EBPTs, especially cognitive-behavioral therapies (CBT), are well-established yet often hard to access.

Objective

Describe and classify the various strategies reported to improve access to CBT for anxiety disorders.

Methods

Scoping review with a keyword search of several databases + additional grey literature documents reporting on strategies to improve access to CBT for anxiety disorders. A thematic and inductive analysis of data based on grounded theory principles was conducted using NVivo.

Results

We propose to classify strategies to improve access to CBT for anxiety disorders as either "Contributing to the evidence base," "Identifying CBT delivery modalities to adopt in practice," "Building capacity for CBT delivery," "Attuning the process of access to local needs," "Engaging potential service users," or "Improving programs and policies." Each of these strategies is defined, and critical information for their operationalization is provided, including the actors that could be involved in their implementation.

Implications

This scoping review highlights gaps in implementation research regarding improving access to EBPTs that should be accounted for in future studies.

A pragmatic randomized controlled trial of a group self-management support program versus treatment-as-usual for anxiety disorders: study protocol

BACKGROUND

The integration of a personal recovery-oriented practice in mental health services is an emerging principle in policy planning. Self-management support (SMS) is an intervention promoting recovery that aims at educating patients on the nature of their mental disorder, improving their strategies to manage their day-to-day symptoms, fostering self-efficacy and empowerment, preventing relapse, and promoting well-being. While SMS is well established for chronic physical conditions, there is a lack of evidence to support the implementation of structured SMS programs for common mental disorders, and particularly for anxiety disorders. This study aims to examine the effectiveness of a group-based self-management support program for anxiety disorders as an add-on to treatment-as-usual in community-based care settings.

METHODS/DESIGN

We will conduct a multicentre pragmatic randomized controlled trial with a pre-treatment, post-treatment (4-month post-randomization), and follow-ups at 8, 12 and 24-months. TREATMENT AND CONTROL GROUPS: a) group self-management support (10 weekly 2.5-h group web-based sessions with 10-15 patients with two trained facilitators); b) treatment-as-usual. Participants will include adults meeting DSM-5 criteria for Panic Disorder, Agoraphobia, Social Anxiety Disorder, and/or Generalized Anxiety Disorder. The primary outcome measure will be the Beck Anxiety Inventory; secondary outcome measures will comprise self-reported instruments for anxiety and depressive symptoms, recovery, self-management, quality of life, and service utilisation.

STATISTICAL ANALYSIS

Data will be analysed based on intention-to-treat with a mixed effects regression model accounting for between and within-subject variations in the effects of the intervention.

DISCUSSION

This study will contribute to the limited knowledge base regarding the effectiveness of structured group self-management support for anxiety disorders. It is expected that changes in patients' self-management behaviour will lead to better anxiety management and, consequently, to improved patient outcomes.

Minimally Adequate Mental Health Treatment and Mortality in Primary Care Older Adults With Depression and Anxiety

Receipt of quality mental health (MH) care can influence mortality. Given the scarce literature on the topic, the aim was to assess the 3-year risk of mortality in older adults (OA) associated with receiving adequate MH treatment for depression/anxiety in an epidemiologic context. The study sample included 358 OA with depression/anxiety recruited in primary care practices and followed prospectively for 3 years. Mortality was assessed from vital statistics data. Adequate care was based on receipt of pharmacotherapy, follow-up care and psychotherapy. Propensity score analysis was carried out where the inverse probability (IPW) of receiving adequate treatment was calculated. Time to event analyses with IPW was used to assess the effect of receipt of adequate MH treatment on the risk of mortality controlling for individual and health system factors. The results showed that receipt of adequate MH treatment reduced the risk of mortality (HR0.44; 95% CI: 0.22 – 0.99). Individual factors that increased mortality were male sex, being single, reduced functional status and cognitive functioning, # physical disorders, current smoking; while exercise reduced risk. Health system factors such as past # of hospitalizations increased the risk; while # of emergency department visits and continuity of care reduced mortality. Finally, treating depression/anxiety with minimal follow-up care and pharmacotherapy or psychotherapy has a significant impact on reducing mortality in OA. Primary care physicians should recognize the important potential impact of years of lives saved when providing quality MH care to OA.

Adoption of care management activities by primary care nurses for people with common mental disorders and physical conditions: A multiple case study

WHAT IS KNOWN ON THE SUBJECT?: The collaborative care model is a well-known model to improve care quality for people with common mental disorders and physical conditions in primary care. The role of care manager is central to the collaborative care model, and primary care nurses are well-positioned to play that role. Adopting the role of care manager by primary care nurses is challenging due to several contextual factors; however, few implementation studies examined the context and current practices before implementing the role of care manager and the collaborative care model. WHAT THE PAPER ADDS TO EXISTING KNOWLEDGE?: The paper contributes to the advancement of knowledge about the pre-assessment of current practices before implementing the collaborative care model and the role of care manager. The paper offers a better understanding of the relationships between the context and the performance of care management activities by primary care nurses. The paper describes an innovative analysis technique to assess the gap between care management activities recommended in the collaborative care model and actual nursing activities. WHAT ARE THE IMPLICATIONS FOR PRACTICE?: Primary care nurses would benefit from having timely access to clinical support from mental health nurse practitioners in order to build their competency. Determinants of practice and the analysis technique to assess current practices will help other researchers or quality improvement teams to develop their plan when implementing the role of care manager. ABSTRACT: Introduction Few studies assessed current nursing practices before implementing the collaborative care model and the role of care manager for people with common mental disorders (CMDs) and physical conditions in primary care settings. Aim Evaluate the main determinants of practice that influence the adoption of care management activities by primary care nurses for people with CMDs and physical conditions. Methods A qualitative multiple case study was conducted in three primary care clinics. A total of 33 participants were recruited. Various data sources were combined: interviews (n = 32), nurse-patient encounters' observations (n = 7), documents and summaries of meetings with stakeholders (n = 8). Results Seven determinants were identified (1) access to external mental health resources; (2) clarification of local CMD care trajectory; (3) compatibility between the coordination of nursing work and the role of care manager; (4) availability of mental health resources within the primary care clinic; (5) competency in care management and competency building; (6) responsibility sharing between the general practitioner and the primary care nurse; and (7) common understanding of the patient treatment plan. Implications for practice To build their competency in care management for people with CMDs, primary care nurses would benefit from having clinical support from mental health nurse practitioners.

Transdiagnostic internet cbt for mixed anxiety and depressive: Results from a feasibility study in primary care

Introduction

In response to the treatment gap for anxiety and depressive disorders, psychological treatments with innovative modalities and high implementation potential are essential. Internet CBT (iCBT) is a cost/effective approach that could improve access to a low-intensity evidence-based CBT intervention.

Objectives

To assess the feasibility and acceptability of the French adaptation of the physician-prescribed six-lesson This Way Up transdiagnostic iCBT program for mixed anxiety and depressive disorders developed in Australia.

Methods

Feasibility study with pre- post-intervention evaluations, including an embedded qualitative study in Family Medicine Groups (Quebec, Canada). Inclusion criteria comprise a family physician diagnosis of Major Depression, Panic Disorder, Agoraphobia, Social Anxiety Disorder or Generalized Anxiety Disorder. Primary self-reported outcomes: PHQ-9 (depression) and GAD-7 (anxiety); secondary measures include diagnostic-specific scales and health service utilisation.

Results

Family physicians (N=21) from five Family Medicine Groups prescribed iCBT to 45 patients (30 women, 15 men; mean age = 39.7), 31 initiated the program. To date, 20 patients completed 5 or 6 lessons, nine completed between 2 and 4. Intervention and post-treatment assessments are ongoing, results forthcoming. Results of semi-structured interviews with patients (N=15) and family physicians (ongoing) on iCBT acceptability indicate it is beneficial, practical and easy to use. Program adherence requires patient readiness and determination and could be fostered by motivational support from clinicians.

Conclusions

Results support this French iCBT program’s scaling-up potential to contribute to reducing the gap in evidence-based treatments for common mental disorders. Its implementation in primary care could improve the effectiveness, efficiency and equity to a rapidly accessible treatment.

Impact of group transdiagnostic cognitive-behavior therapy for anxiety disorders on comorbid diagnoses: Results from a pragmatic randomized clinical trial in primary care

BACKGROUND

Anxiety and depressive disorders are the most common mental illnesses worldwide, with most individuals meeting criteria for more than one diagnosis. Most cognitive-behavioral therapy (CBT) approaches target only one disorder at a time, resulting in the need to treat comorbid diagnoses sequentially. Transdiagnostic CBT protocols have been developed that simultaneously treat principal and comorbid disorders.

METHOD

The current study reports on a secondary analysis of data from a pragmatic effectiveness randomized trial of group tCBT in comparison to treatment-as-usual (TAU) in primary care. Of the trial sample of 231 patients, 191 had at least one comorbid diagnosis of clinical severity at T0.

RESULTS

Overall rates of comorbidity decreased over time (82.0% at T0, 45.0% at T1, 45.7% at T3) and those receiving tCBT showed a significantly lower rate of comorbidity at T1 (33.7%) than TAU (55.7%) and at T3 (tCBT: 27.9%, TAU: 60.2%). Comorbid diagnosis severity ratings reduced to a significantly greater extent in tCBT than in TAU.

CONCLUSIONS

tCBT is effective in promoting remission of and reducing the severity of comorbid diagnoses. Implications for the treatment of whole persons as opposed to specific diagnoses is discussed.

Deployment of the consultation-liaison model in adult and child-adolescent psychiatry and its impact on improving mental health treatment

Background

Little information exists on the perceptions of psychiatrists regarding the implementation and various impacts of the consultation-liaison model. This model has been used in Quebec (Canada) through the function of specialist respondent-psychiatrists (SRP) since 2009. This study assessed the main activities, barriers or facilitators, and impact of SRP in adult and child-adolescent psychiatry on the capacity of service providers in primary care and youth centers to treat patients with mental health disorders (MHD).

Methods

Data included 126 self-administered questionnaires from SRP and semi-structured interviews from 48 SRP managers. Mixed methods were used, with qualitative findings from managers complementing the SRP survey. Comparative analyses of SRP responses in adult versus child-adolescent psychiatry were also conducted.

Results

Psychiatrists dedicated a median 24.12 h/month to the SRP function, mainly involving case discussions with primary care teams or youth centers. They were confident about the level of support they provided and satisfied with their influence in clinical decision-making, but less satisfied with the support provided by their organizations. SRP evaluated their impacts on clinical practice as moderate, particularly among general practitioners (GP). SRP working in child-adolescent psychiatry were more comfortable, motivated, and positive about their overall performance and impact than in adult psychiatry. Organizational barriers (e.g. team instability) were most prevalent, followed by system-level factors (e.g. network size and complexity, lack of resources, model inflexibility) and individual factors (e.g. GP reluctance to treat patients with MHD). Organizational facilitators included support from family medicine group directors, collaboration with university family medicine groups and coordination by liaison nurses; at the system level, pre-existing relationships and working in the same institution; while individual-level facilitators included SRP personality and strong organizational support.

Conclusion

Quebec SRP were implemented sparingly in family medicine groups and youth centers, while SRP viewed their overall impact as moderate. Results were more positive in child-adolescent psychiatry than in adult psychiatry. Increased support for the SRP function, adapting the model to GP in need of more direct support, and resolving key system issues may improve SRP effectiveness in terms of team stability, coordination among providers, access to MH services and readiness to implement innovations.

Group transdiagnostic cognitive-behavior therapy for anxiety disorders: a pragmatic randomized clinical trial

BACKGROUND

Transdiagnostic group cognitive-behavioral therapy (tCBT) is a delivery model that could help overcome barriers to large-scale implementation of evidence-based psychotherapy for anxiety disorders. The aim of this study was to assess the effectiveness of combining group tCBT with treatment-as-usual (TAU), compared to TAU, for the treatment of anxiety disorders in community-based mental health care.

METHODS

In a multicenter single-blind, two-arm pragmatic superiority randomized trial, we recruited participants aged 18-65 who met DSM-5 criteria for principal diagnoses of generalized anxiety disorder, social anxiety disorder, panic disorder, or agoraphobia. Group tCBT consisted of 12 weekly 2 h sessions. There were no restrictions for TAU. The primary outcome measures were the Beck Anxiety Inventory (BAI) and clinician severity rating from the Anxiety and Related Disorders Interview Schedule for DSM-5 (ADIS-5) for the principal anxiety disorder at post-treatment, with intention-to-treat analysis.

RESULTS

A total of 231 participants were randomized to either tCBT + TAU (117) or TAU (114), with outcome data available for, respectively, 95 and 106. Results of the mixed-effects regression models showed superior improvement at post-treatment for participants in tCBT + TAU, compared to TAU, for BAI [p < 0.001; unadjusted post-treatment mean (s.d.): 13.20 (9.13) v. 20.85 (10.96), Cohen's d = 0.76] and ADIS-5 [p < 0.001; 3.27 (2.19) v. 4.93 (2.00), Cohen's d = 0.79].

CONCLUSIONS

Our findings suggest that the addition of group tCBT into usual care can reduce symptom severity in patients with anxiety disorders, and support tCBT dissemination in routine community-based care.

Sex Differences in Anxiety Disorders in Older Adults

PURPOSE OF REVIEW

Anxiety disorders are the most prevalent mental disorders. Although prevalence estimates are lower in males than females, the disability associated with anxiety disorders has been increasing in males. This review focuses on recent research studying sex differences in anxiety disorders and associated symptoms in older adults.

RECENT FINDINGS

Females are close to three times more likely than males to report most anxiety disorders. Heterogeneity exists in sex-specific lifetime and past-year estimates. Age-appropriate instruments such as the CIDI65+ show higher estimates than previous research. The profiles of females and males with anxiety with respect to depressive and somatization symptoms are different. Age-appropriate standardized mental disorder instruments have been developed and may be useful to overcome the challenges of observed heterogeneity in anxiety disorders and allow for future cross-country comparisons and a better description of the epidemiology and biopsychosocial factors associated with different types of anxiety disorders in older adults.

PARE0016 MINDFULNESS-BASED STRESS REDUCTION TO IMPROVE DEPRESSIVE SYMPTOMS AND RHEUMATOID ARTHRITIS-RELATED CLINICAL OUTCOMES: RESULTS FROM A FEASIBILITY AND ACCEPTABILITY TRIAL

Background:

Despite available highly effective pharmacological treatments, up to 30% of current rheumatoid arthritis (RA) patients remain in quasi-remission, where inflammation is controlled but patients still report unacceptable levels of negative impact of RA (high Patient Global Assessment (PGA) on a 0-10 visual analog scale). PGA levels correlated with depressive symptoms assessed by Center for Epidemiologic Studies- Depression (CES-D) scores. Mindfulness-Based Stress Reduction (MBSR) is relatively inexpensive and reduces both anxiety and depression in several conditions.

Objectives:

To complete a feasibility and acceptability study paving the way for a randomized controlled trial (RCT) of MBSR to improve depressive symptoms and clinical outcomes in RA patients in quasi-remission.

Methods:

A standardized 8-week MBSR program in adults with controlled inflammatory disease (stable SJC ≤ 2/66 and normal CRP; stable treatments) but high CES-D scores (2 groups), high CES-D or anxiety scores (1 group), or PGA higher than Physician Evaluation of Disease Activity (EVA) by ≥2 (1 group). Feasibility was documented using process indicators. Outcomes were measured at baseline and 6 months after the end of MBSR. Disease activity scores (SDAI) and questionnaires on depressive symptoms (CES-D), HAQ, sleep (VAS), fatigue and pain (SF-36), anxiety (GAD-7), PGA were collected. Qualitative interviews based on a theoretical framework of acceptability were conducted following the post-MBSR evaluation.

Results:

We report on the first 21 patients (mean age 59, 91% females) having completed their 6-month follow up evaluation. Factors leading to higher recruitment rates were 1) using pragmatic scores to identify eligible patients (e.g. EVA and PGA), 2) no formal clinical evaluation of mental health and no emphasis on depression in the recruitment material.

MBSR had a highly significant positive impact on depressive symptoms (p=0.003) and anxiety (p=0.025) (Figure), and positive impact on quality of sleep and HAQ. No change in SDAI or joint counts was noted.

During a qualitative interview of 13 participants, most reported that MBSR helped them control their reactions to daily stressful situations. Perceptions were almost uniformly positive towards MBSR, and most appeared to have integrated some part of it in their daily life. No side effects were reported.

Conclusion:

Although recruitment was challenging, a MBSR trial in RA patients in quasi-remission was found acceptable and feasible. Positive impacts on mood and on clinical outcomes were observed. Anxiety and depression scores appear the most sensitive to change and are recommended as the primary outcome for an eventual RCT. MBSR added to conventional treatments might help empower RA patients towards self-management.

Psychological predictors of benzodiazepine discontinuation among older adults: Results from the PASSE 60

BACKGROUND

Long-term benzodiazepine (BZD) use among seniors is mostly inappropriate and associated with adverse health outcomes. To prevent these consequences, withdrawal is crucial, yet knowledge is limited about what predicts BZD discontinuation. Until now, most studies have focused on sociodemographic and BZD intake factors as predictors while neglecting psychological factors. This research addresses this issue by studying how the intensity of depressive symptoms, social support satisfaction, self-perceived competence in the ability to withdraw, and overall quality of sleep predict discontinuation in long-term older consumers.

METHOD

Seventy-three participants aged 60 years and older were enrolled in this study. There were four time measures: before discontinuation (T1), after (T2), 3 months after (T3), and 12 months after (T4). Data were collected in the "Programme d'Aide du Succès au SEvrage" (PASSE-60+) study.

RESULTS

Social support satisfaction predicted discontinuation at T2 and T4. Self-perceived competence in the ability to withdraw and depressive symptoms predicted discontinuation at T4. This later prediction was counterintuitive; higher depressive symptoms at T1 were linked with higher discontinuation success. BZD intake factors (length of use and dose) were good predictors for short term discontinuation. Psychological factors were moderate predictors for short term and good predictors for long term discontinuation.

CONCLUSION

Psychological factors are good predictors of discontinuation and are better predictors than BZD intake factors of long-term discontinuation. Discontinuation programs should focus on social support and self-perceived competence to improve their efficacy. Further studies are needed to acquire a more complete picture of the psychological predictors of discontinuation success. ClinicalTrials.gov Identifier: NCT02281175.

Mindfulness-Based Reduction Stress Reduction for Patients with Rheumatoid Arthritis and Depressive Symptoms: a Pilot Trial

Background : Despite their efficacy at controlling joint inflammation, current treatments of rheumatoid arthritis (RA) leave up to 40% of patients into non-remission. Non-remission, frequently due to persistently negative self-reported impact of RA, was found to be associated with significant persistent depressive symptoms 6-7 months after initiation of arthritis treatment. Mindfulness-Based Stress Reduction (MBSR) is proposed to improve depressive symptoms and RA-related clinical outcomes. To pave the way for an eventual randomized controlled trial, a feasibility and acceptability study of MBSR has been realized. Methods: A standardized 8-week MBSR program was offered to groups of patients with controlled inflammatory disease but high levels of depressive symptoms.Qualitative interviews based on a theoretical framework of acceptability were conducted. Change in depressive symptoms (CES-D tool), fatigue and pain (SF-36), anxiety (GAD-7), pain, disease activity (PtVAS and SDAI scores) was measured over a 6-month period. Results: 27 patients have been recruited (3 distinct MBSR groups). Factors leading to a higher rate of success in recruitment were identified. Despite the small sample, the intervention was found to have a clear impact on depressive symptoms (p=0.004), anxiety (p=0.005), and social functioning (from the SF-36; p=0.04). Patients reported that MBSR gave them the opportunity to control their reactions in face of stressful situations.Perceptions were almost uniformly positive towards MBSR, and most appear to have integrated some part of the intervention in their daily life. Conclusions: Although recruitment was challenging, a MBSR trial on depressed patients with controlled inflammatory disease was found acceptable and feasible within this population. Preliminary clinical results showed positive impacts of such intervention.  

Prevalence and Determinants of Long-Term Utilization of Antidepressant Drugs: A Retrospective Cohort Study

PURPOSE

Antidepressant consumption has risen in recent years, driven by longer treatment duration. The objective of this study was to measure the prevalence of antidepressant long-term and chronic use in the Bologna area, Italy, and to identify their main determinants.

MATERIALS AND METHODS

We conducted a retrospective claims-based cohort study by using the Bologna Local Health Authority data. A cohort of 18,307 incident users of antidepressant drugs in 2013 was selected, and subjects were followed for three years. A long-term utilization was defined as having at least one prescription claimed during each year of follow-up, while chronic utilization was defined as claiming at least 180 defined daily doses per year. Factors associated with chronic and long-term use were identified by univariate and multivariate logistic regressions.

RESULTS

In our cohort, 5448 (29.8%) and 1817 (9.9%) subjects were dispensed antidepressants for a long-term course and in a chronically way, respectively. Older age, antidepressant polytherapy, polypharmacy, and being prescribed the first antidepressant by a hospital physician were all factors independently associated with chronic and long-term prescriptions of antidepressant drugs. Results were reported separately for men and women.

CONCLUSION

Antidepressant long-term and chronic prescriptions are common in the Bologna area. Because longer treatment should be clinically motivated, these results strongly prompt the need to evaluate the actual relevance, as they may indicate potentially inappropriate prescription patterns.

Recruitment, use, and satisfaction with a web platform supporting families of children with suspected or diagnosed developmental coordination disorder: a randomized feasibility trial

Objectives. To determine the feasibility of recruiting families of children with suspected or diagnosed developmental coordination disorder (sdDCD) and explore their satisfaction with a web-based intervention Design. A feasibility randomized trial was conducted. Participants were the parents of 5-12-year-old children with sdDCD. The intervention group had access to online resources, group and private forums, and videoconferencing with a therapist. Main outcomes were recruitement and retention rates. Satisfaction was documented through a post-intervention survey and interview. Results. The recruitment rate was seven participants per month (n = 28 participants) and retention rate was 68%. Satisfaction was moderate. No differences in use and satisfaction were observed between groups. Participants formulated recommendations for improving the intervention, including targeting families earlier in the diagnosis process, and pre-scheduling meetings with therapists. Conclusions. This study demonstrated the feasibility of future trials, and highlighted avenues for improvement. Parent involvement during the development of the intervention is discussed at length. Abbreviations: DCD: Developmental Coordination Disorder; sdDCD: suspected or diagnosed Developmental Coordination Disorder; RCT: randomized-controled trial.

Getting better my way: Feasibility study of a self-management support tool for people with mood and anxiety disorders

OBJECTIVE

Self-management support is recognized as an important component of the management of mood and anxiety disorders. The goal of this feasibility study was to evaluate the acceptability, implementation and perceived usefulness of a new comprehensive self-management tool (Getting better my way) in four care settings in Quebec, Canada.

METHOD

Care providers offered the tool to people with difficulties related to mood or anxiety disorders during a 7-month period. A sample of 71 participants filled out an online survey and 27 accepted to participate in a follow-up interview. Focus groups were conducted with 82 care providers.

RESULTS

Satisfaction ratings were high for the tool overall, the likelihood of recommending it to friends, its attractiveness and interest, and its completion time. Perceived usefulness was high overall and was not related to most demographic and clinical variables. No adverse effects were reported.

CONCLUSION AND IMPLICATIONS FOR PRACTICE

The study highlights that Getting better my way is a comprehensive recovery-oriented tool, considered useful, acceptable and feasible to use in a variety of settings offering services for mood and anxiety disorders. (PsycINFO Database Record (c) 2019 APA, all rights reserved).

Challenges of adopting the role of care manager when implementing the collaborative care model for people with common mental illnesses: A scoping review

This review aimed to identify the main factors influencing the adoption of the role of care manager (CM) by nurses when implementing the collaborative care model (CCM) for common mental illnesses in primary care settings. A total of 19 studies met the inclusion criteria, reporting on 14 distinct interventions implemented between 2000 and 2017 in five countries. Two categories of factors were identified and described as follows: (i) strategies for the CCM implementation (e.g. initial care management training and supervision by a mental health specialist) and (ii) context-specific factors (e.g. organizational factors, collaboration with team members, nurses' care management competency). Identified implementation strategies were mainly aimed towards improving the nurse's care management competency, but their efficacy in developing the set of competencies needed to fulfil a CM role was not well demonstrated. There is a need to better understand the relationship between the nurses' competencies, the care management activities, the strategies used to implement the CCM and the context-specific factors. Strategies to optimize the adoption of the CM role should not be solely oriented towards the individual's competency in care management, but also consider other context-specific factors. The CM also needs a favourable context in order to perform his or her activities with competency.

Case management in primary care for frequent users of healthcare services with chronic diseases and complex care needs: an implementation and realist evaluation protocol

INTRODUCTION

Significant evidence in the literature supports case management (CM) as an effective intervention to improve care for patients with complex healthcare needs. However, there is still little evidence about the facilitators and barriers to CM implementation in primary care setting. The three specific objectives of this study are to: (1) identify the facilitators and barriers of CM implementation in primary care clinics across Canada; (2) explain and understand the relationships between the actors, contextual factors, mechanisms and outcomes of the CM intervention; (3) identify the next steps towards CM spread in primary care across Canada.

METHODS AND ANALYSIS

We will conduct a multiple-case embedded mixed methods study. CM will be implemented in 10 primary care clinics in five Canadian provinces. Three different units of analysis will be embedded to obtain an in-depth understanding of each case: the healthcare system (macro level), the CM intervention in the clinics (meso level) and the individual/patient (micro level). For each objective, the following strategy will be performed: (1) an implementation analysis, (2) a realist evaluation and (3) consensus building among stakeholders using the Technique for Research of Information by Animation of a Group of Experts method.

ETHICS AND DISSEMINATION

This study, which received ethics approval, will provide innovative knowledge about facilitators and barriers to implementation of CM in different primary care jurisdictions and will explain how and why different mechanisms operate in different contexts to generate different outcomes among frequent users. Consensual and prioritised statements about next steps for spread of CM in primary care from the perspectives of all stakeholders will be provided. Our results will offer context-sensitive explanations that can better inform local practices and policies and contribute to improve the health of patients with complex healthcare needs who frequently use healthcare services. Ultimately, this will increase the performance of healthcare systems and specifically mitigate ineffective use and costs.

Treatment adequacy for social anxiety disorder in primary care patients

OBJECTIVES

There is a gap between clinical practice guidelines for social anxiety disorder and clinical practice that needs to be addressed to ensure the delivery of evidence-based treatments. The objectives of this study were: 1) to describe mental health service utilization in a cohort of primary care patients with social anxiety disorder; 2) to examine treatment adequacy for pharmacotherapy and psychotherapy according to indicators based on clinical practice guidelines; and 3) to explore correlates of treatment adequacy.

METHOD

The "Dialogue" project (Quebec, Canada) is a large study conducted in 67 primary care clinics. After a mental health screening in primary care (n = 14 833), participants with anxiety or depressive symptoms took part in a telephone/web structured interview on mental health symptoms and service utilization (n = 1956). This study included 289 participants meeting DSM-IV criteria for social anxiety disorder.

RESULTS

Overall, 86.2% of participants reported consulting for mental health reasons over the past 12 months. Only 23.6% of our sample reported the detection of social anxiety disorder by a healthcare professional in the past 12 months. Approximately 2 in 5 respondents with social anxiety disorder reported receiving pharmacotherapy or psychotherapy meeting our treatment adequacy indicators. Antidepressant medication was the most common treatment. Logistic regression models showed that the detection of major depression (OR = 4.651; 95% CI: 2.559-8.453) or other anxiety disorder(s) (OR = 2.957; 95% CI: 1.555-5.625) were associated with receiving any adequate treatment, but the detection of social anxiety disorder itself was not (OR = 1.420; 95% CI: 0.696-2.899).

CONCLUSION

Low rates of detection and treatment adequacy based on our indicators demonstrate that efforts must be made to ensure the quality of care for individuals with social anxiety disorder in primary care.

A pragmatic randomized controlled trial of group transdiagnostic cognitive-behaviour therapy for anxiety disorders in primary care: study protocol

BACKGROUND

Anxiety disorders are the most common mental disorders in community settings, and they are associated with significant psychological distress, functional and social impairment. While cognitive behaviour therapy (CBT) is the most consistently efficacious psychological treatment for anxiety disorders, barriers preclude widespread implementation of CBT in primary care. Transdiagnostic group CBT (tCBT) focuses on cognitive and behavioural processes and intervention strategies common to different anxiety disorders, and could be a promising alternative to conventional CBT. This study aims to examine the effectiveness of a transdiagnostic group CBT for anxiety disorders program as a complement to treatment-as-usual (TAU) in primary mental health care.

METHODS/DESIGN

The trial is a multicentre pragmatic randomized controlled trial with a pre-treatment, post-treatment, and follow-up at 4, 8 and 12-months design. Treatment and control groups. a) tCBT (12 weekly 2-h group sessions following a manualized treatment protocol); b) TAU for anxiety disorders. Inclusion criteria comprise meeting DSM-5 criteria for primary Panic Disorder, Agoraphobia, Social Anxiety Disorder and/or Generalized Anxiety Disorder. Patients are recruited in three regions in the province of Quebec, Canada. The primary outcome measures are the self-reported Beck Anxiety Inventory and the clinician-administered Anxiety and Related Disorders Interview Schedule for DSM-5 (ADIS-5); secondary outcome measures include treatment responder status based on the ADIS-5, and self-reported instruments for specific anxiety and depression symptoms, quality of life, functioning, and service utilisation.

STATISTICAL ANALYSIS

Intention-to-treat analysis. A mixed effects regression model will be used to account for between- and within-subject variations in the analysis of the longitudinal effects of the intervention.

DISCUSSION

This rigorous evaluation of tCBT in the real world will provide invaluable information to decision makers, health care managers, clinicians and patients regarding the effectiveness of the intervention. Widespread implementation of tCBT protocols in primary care could lead to better effectiveness, efficiency, access and equity for the large number of patients suffering from anxiety disorders that are currently not obtaining evidence-based psychotherapy.

Patterns of benzodiazepines use in primary care adults with anxiety disorders

BACKGROUND

Benzodiazepines are among the most commonly prescribed drugs for anxiety disorders. While they are indicated as adjunctive treatment for short-term use according to clinical practice guidelines, previous studies have shown patterns of long-term use of benzodiazepines, which is problematic due to side effects, dependence and potential of abuse. The aims of this study were to examine among a large sample of primary care adults suffering from anxiety disorders: 1) benzodiazepine use patterns; and 2) correlates of long-term benzodiazepine use.

METHODS

Data were drawn from the "Dialogue" project, a large primary care study conducted in 64 primary care clinics in the province of Quebec, Canada. Following a mental health screening in waiting rooms, patients at risk of anxiety or depression completed the Composite International Diagnostic Interview-Simplified (CIDIS). A sample of 740 adults meeting DSM-IV criteria for Generalized Anxiety Disorder, Panic Disorder or Social Anxiety Disorder in the past 12 months took part in this study.

RESULTS

Benzodiazepines were used by 22.6% of participants with anxiety disorders in our primary care sample. A large majority of benzodiazepine users (88.4%) met our indicator of long-term use, as defined by utilization for more than 12 weeks including regular and as-needed use. Based on a logistic regression model, individual correlates associated with long-term benzodiazepine use included: being 30 years or older, having a comorbid physical illness, meeting criteria for comorbid agoraphobia, reporting the use of sleep-aids, and concurrent SSRI utilization.

LIMITATION

Data collection with self-reported questionnaires may be subject to information bias.

CONCLUSIONS

Despite knowledge of the risks of long-term use of benzodiazepines, this remains a pervasive problem. Clinicians need to be mindful of patterns and risk factors leading to long-term use of benzodiazepines in patients with anxiety disorders. Results of this study should raise awareness regarding appropriate prescription practices for benzodiazepines, including decision-making in initiation, duration of prescription, and use of strategies for discontinuation in current long-term benzodiazepine users.

Case Management in Primary Care for Frequent Users of Health Care Services: A Mixed Methods Study

PURPOSE

This study aimed to evaluate the effects of the V1SAGES case management intervention (Vulnerable Patients in Primary Care: Nurse Case Management and Self-management Support) for frequent users of health care services with chronic disease and complex care needs on psychological distress and patient activation.

METHODS

We used a 2-phase sequential mixed methods design. The first phase was a pragmatic randomized controlled trial with intention-to-treat analysis that measured the effects of the intervention compared with usual care on psychological distress and patient activation before and after 6 months. The second phase had a qualitative descriptive design and entailed thematic analysis of in-depth interviews (25 patients, 6 case management nurses, 9 health managers) and focus groups (8 patients' spouses, 21 family physicians) to understand stakeholders' perceived effects of the intervention on patients.

RESULTS

A total of 247 patients were randomized into the intervention group (n = 126) or the control group (n = 121). Compared with usual care, the intervention reduced psychological distress (odds ratio = 0.43; 95% CI, 0.19-0.95, P = .04), but did not have any significant effect on patient activation (P = .43). Qualitative results suggested that patients and their spouses benefitted from the case management intervention, gaining a sense of security, and stakeholders noted better patient self-management of health.

CONCLUSIONS

Together, our study's quantitative and qualitative results suggest that case management reduces psychological distress, making patients and caregivers feel more secure, whereas impact on self-management is unclear. Case management is a promising avenue to improve outcomes among frequent users of health care with complex needs.

Amorcer un traitement antipsychotique en schizophrénie : la situation au Québec de 1998 à 2006

Contexte Cet article vise à décrire les facteurs associés à la prescription d’antipsychotiques par un psychiatre plutôt qu’un omnipraticien, la prescription d’un antipsychotique de seconde plutôt que de première génération, la prescription d’une multithérapie d’antipsychotiques et le non-renouvellement de la prescription initiale.

Méthodologie Il s’agit d’une étude pharmacoépidémiologique observationnelle avec analyses secondaires d’une banque de données médicoadministratives (RAMQ). Les données disponibles portaient sur un échantillon exhaustif des personnes adultes ayant reçu un diagnostic de schizophrénie et ayant obtenu un antipsychotique couvert par le régime public d’assurance médicaments de 1998 à 2006. Les résultats de régression logistique multiple sont rapportés.

Résultats Parmi les 16 225 personnes éligibles, 46,2 % étaient des femmes et 70 % étaient bénéficiaires d’une aide financière. La clientèle des psychiatres était plus jeune et plus atteinte au niveau de la santé mentale. La multithérapie était associée aux hospitalisations pour psychose, au faible statut socio-économique et à un âge entre 35 et 64 ans. Les antipsychotiques de seconde génération ont pris une place importante au cours de la période à l’étude. Le non-renouvellement était associé à l’abus de substances et était moins fréquent suite à une hospitalisation pour trouble mental.

Conclusions Malgré les limites liées à l’utilisation de données administratives, l’utilisation d’une banque de données exhaustive provenant autant de médecine générale que de spécialité permet à cette étude de brosser un portrait populationnel pertinent pour connaître la situation réelle du traitement incident de la schizophrénie au Québec de 1998 à 2006, une période caractérisée par l’introduction des antipsychotiques de seconde génération.

[Initiating an antipsychotic drug treatment for schizophrenia: the situation in Quebec, Canada, from 1998 to 2006]

Objectives To describe factors associated with the following characteristics of the first prescription of an antipsychotic drug treatment (ADT): 1) prescribing physician type (psychiatrist vs. general practitioner); 2) second-generation vs. first-generation antipsychotic drug; 3) in conjunction with at least one additional antipsychotic drug (multitherapy); 4) never renewed by the patient.Methods This is a pharmacoepidemiologic study using administrative data from the Régie de l'assurance maladie du Québec (RAMQ), the public healthcare insurer in Quebec, Canada. Available data sample was exhaustive for adults with a diagnosis of schizophrenia who received an ADT under RAMQ drug coverage from 1998 to 2006. We report multiple logistic regression results.Results Among 16,225 patients who met inclusion criteria 46.2% were women and 70% were beneficiaries of governmental financial assistance. Patients who had their ADT prescribed by psychiatrists tended to be younger and were more burdened by their mental illness. Multitherapy was associated with hospitalization with a psychotic disorder as main diagnosis, lower socioeconomic status, and age between 35 and 64. Second-generation antipsychotic use became progressively more prominent during the period under study. Antipsychotic non renewal was correlated with substance use disorders and was less likely to happen following hospitalization with a psychiatric main diagnosis. Conclusions Although this study is subject to the intrinsic limitations of secondary analysis of administrative data, the database available for study was exhaustive within the Quebec healthcare system and included data from both general practice and specialized care, which allowed us to draw a relevant picture of how ADT were initiated for schizophrenia in Quebec, Canada, from 1998 to 2006. This timeframe is especially relevant since the 1990s were marked by the introduction of second-generation antipsychotics in Canada.

Comparative effectiveness and safety of antipsychotic drugs in schizophrenia treatment: a real-world observational study

OBJECTIVE

The objective was to compare, in a real-world setting, the risk of mental and physical health events associated with different antipsychotic drugs (clozapine, olanzapine, risperidone, quetiapine and first-generation antipsychotics) in patients with SZ.

METHODS

This is a retrospective cohort study using administrative data. Outcome measures included any mental health event (suicide, hospitalization or emergency visit for mental disorders) and physical health event (death other than suicide, hospitalization or emergency visit for physical disorders). Cox proportional hazard models were used to estimate the hazard ratios of the events associated with the use of the different antipsychotic drugs.

RESULTS

The cohort included 18 869 adult patients living in the province of Quebec (Canada) with SZ and starting antipsychotic drugs between January 1998 and December 2005. Results show that quetiapine and not using any antipsychotics were associated with an increased risk of mental and physical health events as compared to other drugs. The second finding is the confirmation of better performance of clozapine. The results were robust across sensitivity analyses.

CONCLUSION

Both findings call for an international public health and drug agencies surveillance of 'real-world' antipsychotic medication to ensure the optimal choices in treatment guidelines for SZ.

A qualitative study of perceived needs and factors associated with the quality of care for common mental disorders in patients with chronic diseases: the perspective of primary care clinicians and patients

BACKGROUND

The prevalence of comorbid anxiety and depressive disorders is high among patients with chronic diseases in primary care, and is associated with increased morbidity and mortality rates. The detection and treatment of common mental disorders in patients with chronic diseases can be challenging in the primary care setting. This study aims to explore the perceived needs, barriers and facilitators for the delivery of mental health care for patients with coexisting common mental disorders and chronic diseases in primary care from the clinician and patient perspectives.

METHODS

In this qualitative descriptive study, we conducted semi-structured interviews with clinicians (family physician, nurse, psychologist, social worker; n = 18) and patients (n = 10) from three primary care clinics in Quebec, Canada. The themes explored included clinician factors (e.g., attitudes, perception of roles, collaboration, management of clinical priorities) and patient factors (e.g., needs, preferences, access to care, communication with health professionals) associated with the delivery of care. Qualitative data analysis was conducted based on an interactive cyclical process of data reduction, data display and conclusion drawing and verification.

RESULTS

Clinician interviews highlighted a number of needs, barriers and enablers in the provision of patient services, which related to inter-professional collaboration, access to psychotherapy, polypharmacy as well as communication and coordination of services within the primary care clinic and the local network. Two specific facilitators associated with optimal mental health care were the broadening of nurses' functions in mental health care and the active integration of consulting psychiatrists. Patients corroborated the issues raised by the clinicians, particularly in the domains of whole-person care, service accessibility and care management.

CONCLUSIONS

The results of this project will contribute to the development of quality improvement interventions to increase the uptake of organizational and clinical evidence-based practices for patients with chronic diseases and concurrent common mental disorders, in priority areas including collaborative care, access to psychotherapy and linkages with specialized mental health care.
