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.

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.

Health care system costs related to potentially inappropriate medication use involving opioids in older adults in Canada.

BACKGROUND: Older adults are at risk of potentially inappropriate medication use given polypharmacy, multimorbidity, and age-related changes, which contribute to the growing burden associated with opioid use. The objective of this study was to estimate the costs of health service utilization attributable to opioid use and potentially inappropriate medication use involving opioids in older adults in a public health care system. METHODS: The sample included 1201 older adults consulting in primary care, covered by the public drug plan, without a cancer diagnosis and opioid use in the year before interview. Secondary analyses were conducted using two data sources: health survey and provincial administrative data. Health system costs included inpatient and outpatient visits, physician billing, and medication costs. Unit costs were calculated using annual financial and activity reports from 2013-2014, adjusted to 2022 Canadian dollars. Opioid use and potentially inappropriate medication use involving opioids were identified over 3 years. Generalized linear models with gamma distribution were employed to model 3-year costs associated with opioid use and potentially inappropriate medication use involving opioids. A phase-based approach was implemented to provide descriptive results on the costs associated with each phase: i) no use, ii) opioid use, and iii) potentially inappropriate medication use involving opioids. RESULTS: Opioid use and potentially inappropriate medication use involving opioids were associated with adjusted 3-year costs of $2,222 (95% CI: $1,179-$3,264) and $8,987 (95% CI: $7,370-$10,605), respectively, compared to no use. In phase-based analyses, costs were the highest during inappropriate use. CONCLUSIONS: Potentially inappropriate medication use involving opioids is associated with higher costs compared to those observed with opioid use and no use. There is a need for more effective use of health care resources to reduce costs for the health care system.

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. TRIAL REGISTRATION: ClinicalTrials.gov: NCT02811458, 23/06/2016.

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.

Health care system and patient costs associated with receipt of minimally adequate treatment for depression and anxiety disorders in older adults.

BACKGROUND: Depression and anxiety disorders in older adults are associated with a great burden. Research has shown that less than 50% of adults receive adequate treatment in primary care settings for these disorders. Rare are the studies however assessing adequate treatment in older adults and associated costs from the societal perspective. Given the episodic nature of common mental disorders, this study aims to assess the three-year costs from a restricted societal perspective (including health system and patient perspectives) associated with receipt of minimally adequate treatment for depression and anxiety disorders in older adults consulting in primary care. METHODS: This primary care cohort study included 358 older adults aged 65 years and older with either a self-reported or physician diagnosis of depression or an anxiety disorder covered under Quebec's public drug plan. Receipt of minimally adequate treatment was assessed according to Canadian guidelines and relevant reports. Outpatient and inpatient service use, medication costs and physician billing fees were obtained from provincial administrative databases. Unit costs were calculated using provincial financial and activity reports and relevant literature. A propensity score was created to estimate the probability of receiving minimally adequate treatment and the inverse probability was used as a weight in analyses. Generalized linear models, with gamma distribution and log link, were conducted to assess the association between receipt of minimally adequate treatment and costs. RESULTS: Overall, receipt of minimally adequate treatment was associated with increased three-year costs averaging $5752, $536, $6266 for the health system, patient and societal perspectives, respectively, compared to those not receiving minimally adequate treatment. From the health system perspective, participants receiving minimally adequate treatment had higher costs related to emergency department (ED) (difference: $457, p = 0.001) and outpatient visits (difference: $620, p < 0.001), inpatient stays (difference: $2564, p = 0.025), drug prescriptions (difference: $1243, p = 0.002) and physician fees (difference: $1224, p < 0.001). From the patient perspective, receipt of minimally adequate treatment was associated with higher costs related to loss of productivity related to ED (difference: $213, p < 0.001) and outpatient visits (difference: $89, p < 0.001). CONCLUSIONS: Older adults receiving minimally adequate treatment for depression and anxiety disorders incurred higher societal costs reaching $2089 annually compared to older adults not receiving minimally adequate treatment. The main cost drivers were attributable to hospitalizations and prescription drug costs.

Perceived Need for Mental Health Care and Associated Factors and Outcomes in Older Adults Consulting in Primary Care.

OBJECTIVE: To assess the individual and health system factors and health-related outcomes associated with perceived need for mental health care in older adults consulting in primary care. METHOD: This longitudinal cohort study was conducted among 771 cognitively intact older adults aged ≥65 years recruited in primary care practices in Quebec between 2011 and 2013 and followed 4 years later. Predisposing, enabling and need factors were based on Andersen's framework on help-seeking behaviors. Health-related outcomes included course of common mental disorders (CMDs), change in quality of life and societal costs. Perceived need for care (PNC) was categorized as no need, met and unmet need. Multinomial regression analyses were conducted to assess the association between study variables and PNC in the overall and the subsample of participants with a CMD at baseline. RESULTS: As compared with individuals reporting no need, those with an unmet need were more likely to have cognitive decline and lower continuity of care; while those with a met need were more likely to report decreased health-related quality of life. As compared with individuals with an unmet need, those reporting a met need were more likely to report ≥ 3 physical diseases and an incident and persistent CMD, and less likely to show cognitive decline. In participants with a CMD, individuals reporting a met as compared with no need were more likely to be categorized as receiving minimally adequate care and a persistent CMD. Need for care was not associated with societal costs related to health service use. CONCLUSIONS: Overall, physicians should focus on individuals with cognitive impairment and lower continuity of care which was associated with unmet mental health need. Improved follow-up in these populations may improve health care needs and outcomes.

Protocol for a multi-phase, mixed methods study to develop and evaluate culturally adapted CBT to improve community mental health services for Canadians of south Asian origin.

BACKGROUND: Canadians of South Asian (SA) origin comprise the largest racialized group in Canada, representing 25.6% of what Statistics Canada terms "visible minority populations". South Asian Canadians are disproportionately impacted by the social determinants of health, and this can result in high rates of mood and anxiety disorders. These factors can negatively impact mental health and decrease access to care, thereby increasing mental health inequities. Cognitive Behavioural Therapy (CBT) in its current form is not suitable for persons from the non-western cultural backgrounds. Culturally adapted Cognitive Behavioural Therapy (CaCBT) is an evidence-based practice. CaCBT is more effective than standard CBT and can reduce dropouts from therapy compared with standard CBT. Thus, CaCBT can increase access to mental health services and improve outcomes for immigrant, refugee and ethno-cultural and racialized populations. Adapting CBT for growing SA populations in Canada will ensure equitable access to effective and culturally appropriate interventions. METHODS: The primary aim of the study is to develop and evaluate CaCBT for Canadian South Asian persons with depression and anxiety and to gather data from stakeholders to develop guidelines to culturally adapt CBT. This mixed methods study will use three phases: (1) cultural adaptation of CBT, (2) pilot feasibility of CaCBT and (3) implementation and evaluation of CaCBT. Phase 1 will use purposive sampling to recruit individuals from four different groups: (1) SA patients with depression and anxiety, (b) caregivers and family members of individuals affected by anxiety and depression, (c) mental health professionals and (d) SA community opinion leaders. Semi-structured interviews will be conducted virtually and analysis of interviews will be informed by an ethnographic approach. Phase 2 will pilot test the newly developed CaCBT for feasibility, acceptability and effectiveness via quantitative methodology and a randomized controlled trial, including an economic analysis. Phase 3 will recruit therapists to train and evaluate them in the new CaCBT. DISCUSSION: The outcome of this trial will benefit health services in Canada, in terms of helping to reduce the burden of depression and anxiety and provide better care for South Asians. We expect the results to help guide the development of better services and tailor existing services to the needs of other vulnerable groups. TRIAL REGISTRATION: ClinicalTrials.gov NCT04010890.

Public Funding of Evidence-Based Psychotherapy for Common Mental Disorders: Increasing Calls for Action in Canadian Provinces.

Canada's provinces are without a publicly funded psychotherapy program for common mental disorders despite evidence that psychological services help reduce the length and number of depressive episodes, symptoms of post-traumatic stress and associated negative outcomes (hospitalizations and suicide attempts). Studies also show that including psychological services as part of the service package offered under the public health plan for those without access pays for itself. We posit that a publicly funded psychotherapy program in Canada, including digitized self-guided psychotherapy platforms for common mental disorders, will lead to improved population health useful in the COVID-19 context and beyond.

The Factors Associated with 3-Year Mortality Stratified by Physical and Mental Multimorbidity and Area of Residence Deprivation in Primary Care Community-Living Older Adults.

Objectives: To examine the risk factors of mortality stratified by physical and mental multimorbidity (PMM) and area socioeconomic status. Methods: Cox regression analyses were used to study 3-year all-cause mortality in primary care older adults stratified by PMM status, and area of residence material and social deprivation. Results: There were socioeconomic differences in the associations between PMM and mortality. Continuity of care decreased mortality risk in moderately and most deprived areas. Satisfaction with medical consultations decreased mortality risk in moderately deprived areas. Current smoking increased mortality in those living in moderately and most deprived areas. Physical activity reduced mortality only in individuals without PMM. Higher cognition was associated with reduced mortality in individuals living in moderately deprived areas. Discussion: Public health policies should be further encouraged in primary care, aiming at increased continuity of care, quality of interactions with patients, and prevention strategies including smoking cessation programs and physical activity promotion.

Sociodemographic factors and beliefs about medicines in the uptake of pharmacogenomic testing in older adults.

Aim: To assess the impact of sociodemographic factors and beliefs about medicines on the uptake of pharmacogenomic testing in older adults in a public healthcare system. Materials & methods: Data are based on a sample of 347 primary care older adults. Results: Most respondents (90%) were willing to provide a saliva sample and 47% were willing to pay for it. Increased age (odds ratio: 0.91; p = 0.04) and negative beliefs about the harmfulness of medicines (odds ratio: 0.68; p = 0.02) were associated with a decreased willingness to provide a sample. Lower education (less than university, odds ratio: 0.54; p = 0.04) was associated with a decreased willingness to pay. Conclusion: Education and beliefs about medicines are important factors in the acceptability of pharmacogenomic testing in older adults.

Translation and Cultural Adaptation of the Patient Self-Administered Financial Effects (P-SAFE) Questionnaire to Assess the Financial Burden of Cancer in French-Speaking Patients.

People living with and beyond cancer (PLC) experience financial hardship associated with the disease and its treatment. Research demonstrates that the "economic toxicity" of cancer can cause distress and impair well-being, health-related quality of life and, ultimately, survival. The Patient Self-Administered Financial Effects (P-SAFE) questionnaire was created in Canada and tested in English. The objective of this study is to describe the processes of translation and cultural adaptation of the P-SAFE for use with French speaking PLC in Canada. The Canadian P-SAFE questionnaire was translated from English to French in collaboration with the developer of the initial version, according to the 12-step process recommended by the Patient-Reported Outcome (PRO) Consortium. These steps include forward and backward translation, a multidisciplinary expert committee, and cross-cultural validation using think-aloud, probing techniques, and clarity scoring during cognitive interviewing. Translation and validation of the P-SAFE questionnaire were performed without major difficulties. Minor changes were made to better fit with the vocabulary used in the public healthcare system in Quebec. The mean score for clarity of questions was 6.4 out of a possible 7 (totally clear) Cognitive interviewing revealed that lengthy questionnaire instructions could be confusing. Our team produced a Canadian-French version of the P-SAFE. After minor rewording in the instructions, the P-SAFE questionnaire appears culturally appropriate for use with French-speaking PLC in Canada. Further testing of the French version will require evaluation of psychometric properties of validity and reliability.

Collaborative governance in the Quebec Cancer Network: a realist evaluation of emerging mechanisms of institutionalization, multi-level governance, and value creation using a longitudinal multiple case study design.

BACKGROUND: People living with and beyond cancer (PLC) receive various forms of specialty care at different locations and many interventions concurrently or over time. They are affected by the operation of professional and organizational silos. This results in undue delays in access, unmet needs, sub-optimal care experiences and clinical outcomes, and human and financial costs for PLCs and healthcare systems. National cancer control programs advocate organizing in a network to coordinate actions, solve fragmentation problems, and thus improve clinical outcomes and care experiences for every dollar invested. The variable outcomes of such networks and factors explaining them have been documented. Governance is the "missing link" for understanding outcomes. Governance refers to the coordination of collective action by a body in a position of authority in pursuit of a common goal. The Quebec Cancer Network (QCN) offers the opportunity to study in a natural environment how, why, by whom, for whom, and under what conditions collaborative governance contributes to practices that produce value-added outcomes for PLCs, healthcare providers, and the healthcare system. METHODS/DESIGN: The study design consists of a longitudinal case study, with multiple nested cases (4 local networks nested in the QCN), mobilizing qualitative and quantitative data and mixed data from various sources and collected using different methods, using the realist evaluation approach. Qualitative data will be used for a thematic analysis of collaborative governance. Quantitative data from validated questionnaires will be analyzed to measure relational coordination and teamwork, care experience, clinical outcomes, and health-related health-related quality of life, as well as a cost analysis of service utilization. Associations between context, governance mechanisms, and outcomes will be sought. Robust data will be produced to support decision-makers to guide network governance towards optimized clinical outcomes and the reduction of the economic toxicity of cancer for PLCs and health systems.

Assessing quality indicators related to mental health emergency room utilization.

BACKGROUND: This descriptive study compared 2014-15 to 2005-06 data on the quality of mental health services (MHS) in relation to emergency room (ER) use to assess the impact of the 2005 Quebec MH reform regarding access, continuity and appropriateness of care for patients with mental illnesses (PMI). METHODS: Data emanated from the Quebec Integrated Chronic Disease Surveillance System (Quebec/Canada). Participants (865,255 for 2014-15; 817,395 for 2005-06) were age 12 or over, with at least one MI, including substance use disorders (SUD), diagnosed during an ER visit, outpatient treatment or hospitalization. Variables included: access (ER use/frequency, hospitalization rates, outpatient consultations preceding an ER visit), care continuity (outpatient consultations following an ER visit/hospitalization, consecutive returns to the ERs), and care appropriateness (high ER use, recurrence of yearly ER visits, length of hospitalization). Frequency distributions were calculated on sex, age and geographic area for ER visits/hospitalizations in 2014-15, and between 2014 and 15 and 2005-06. RESULTS: PMI accounted for 12 % of the Quebec population in 2014-15 (n = 865,255), of whom 39% visited an ER for any reason. Amount and frequency of ER use and number/length of hospitalizations were almost twice as high for PMI versus patients without MI; 17% of PMI were also high/very high ER users and were frequently hospitalized. Among PMI, ER users were also frequent users of outpatient services despite a lack of follow-up appointments after ER visits or hospitalizations. Findings revealed some positive changes over time, such as decreased ER and hospitalization rates; yet overall access, continuity and appropriateness of care, as measured in this study, remained low. CONCLUSIONS: This study demonstrated that the Quebec reform did not produce a substantial impact on ER use or substantially improved care, as hypothesized. Better access and continuity of care should be promoted to reduce the high prevalence of ER use among PMI. Quality improvement in MHS may be realized if ERs are supported by substantial and well-integrated community MH networks.

Off-label use of antipsychotics and associated factors in community living older adults.

BACKGROUND: Given the common off-label use of antipsychotics (AP), we aimed to assess the factors associated with this use in community living older adults. METHODS: The study sample consisted of a large representative sample of older adults (n = 4108), covered under a public drug insurance plan in Canada. Off-label use of antipsychotics was defined by the absence of an approved indication for this use, according to Health Canada's drug product database. Multinomial logistic regression was used to assess the factors associated with off-label use. RESULTS: The prevalence of antipsychotics use was 2.5%, of which 78% was off-label. Compared to non-use, off-label antipsychotics use was negatively associated with advanced age (≥75 vs. 65-74 years old) (OR: 0.46; 95%CI: 0.27-0.78); and positively associated with higher education level (OR: 2.68; 95% CI: 1.64-4.40), higher number of outpatient visits (≥6) (OR: 2.39; 95%CI: 1.34-4.25), antidepressant or benzodiazepine use (OR: 5.81; 95%CI: 3.31-10.21), and the presence of an organic brain syndrome & Alzheimer's (OR: 5.73; 95%CI: 1.74-18.89). Compared to labeled use, off-label use was less likely in those with major depression (OR: 0.02; 95%CI: <0.01-0.11) and with insomnia (OR: 0.13; 95%CI: 0.02-0.91). CONCLUSIONS: The majority of antipsychotics prescribed to community living older adults were off-label. This off-label use was more likely in complex clinical cases with multiple outpatient visits and other psychotropic drugs use. Further research should focus on the long-term effects associated with off-label use of antipsychotics.

Six-month prevalence and correlates of generalized anxiety disorder among primary care patients aged 70 years and above: Results from the ESA-services study.

OBJECTIVES: To estimate the 6-month prevalence of generalized anxiety disorder (GAD) in primary care patients aged 70 years and above and to describe their clinical profile, including types of worries. METHODS/DESIGN: Participants (N = 1193) came from the Étude sur la Santé des Aînés (ESA) services study conducted in Quebec, Canada. An in-person structured interview was used to identify GAD and other anxiety/depressive disorders as well as to identify types of worries. Three groups were created (ie, patients with GAD, patients with another anxiety disorder, and patients without anxiety disorders) and compared on several sociodemographic and clinical characteristics using multinomial logistic regression analyses. RESULTS: The 6-month prevalence of GAD was 2.7%. Findings also indicated that the most common types of worries were about health, being a burden for loved ones, and losing autonomy. Compared with respondents without anxiety disorders, older patients with GAD were more likely to be women, be more educated, suffer from depression, use antidepressants, be unsatisfied with their lives, and use health services. In comparison with respondents with another anxiety disorder, those with GAD were 4.5 times more likely to suffer from minor depression. CONCLUSIONS: GAD has a high prevalence in primary care patients aged 70 years and above. Clinicians working in primary care settings should screen for GAD, since it remains underdiagnosed. In addition, it may be associated with depression and life dissatisfaction. Screening tools for late-life GAD should include worry themes that are specific to aging.

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.

Effect of personalised citizen assistance for social participation (APIC) on older adults' health and social participation: study protocol for a pragmatic multicentre randomised controlled trial (RCT).

INTRODUCTION: The challenges of global ageing and the growing burden of chronic diseases require innovative interventions acting on health determinants like social participation. Many older adults do not have equitable opportunities to achieve full social participation, and interventions might underempower their personal and environmental resources and only reach a minority. To optimise current practices, the Accompagnement-citoyen Personnalisé d'Intégration Communautaire (APIC), an intervention demonstrated as being feasible and having positive impacts, needs further evaluation. METHODS AND ANALYSIS: A pragmatic multicentre, prospective, two-armed, randomised controlled trial will evaluate: (1) the short-term and long-term effects of the APIC on older adults' health, social participation, life satisfaction and healthcare services utilisation and (2) its cost-effectiveness. A total of 376 participants restricted in at least one instrumental activity of daily living and living in three large cities in the province of Quebec, Canada, will be randomly assigned to the experimental or control group using a centralised computer-generated random number sequence procedure. The experimental group will receive weekly 3-hour personalised stimulation sessions given by a trained volunteer over the first 12 months. Sessions will encourage empowerment, gradual mobilisation of personal and environmental resources and community integration. The control group will receive the publicly funded universal healthcare services available to all Quebecers. Over 2 years (baseline and 12, 18 and 24 months later), self-administered questionnaires will assess physical and mental health (primary outcome; version 2 of the 36-item Short-Form Health Survey, converted to SF-6D utility scores for quality-adjusted life years), social participation (Social Participation Scale) and life satisfaction (Life Satisfaction Index-Z). Healthcare services utilisation will be recorded and costs of each intervention calculated. ETHICS AND DISSEMINATION: The Research Ethics Committee of the CIUSSS Estrie - CHUS has approved the study (MP-31-2018-2424). An informed consent form will be read and signed by all study participants. Findings will be published and presented at conferences. TRIAL REGISTRATION NUMBER: NCT03161860; Pre-results.

The prospective and concurrent effect of exercise on health related quality of life in older adults over a 3 year period.

BACKGROUND: It is not clear whether socioeconomic status influences health outcomes among older adults through its effect on physical activity. The aim of this study was to assess the effect of sex and neighborhood socio-economic status on the change in health related quality of life (HR-QOL) as a function of physical activity over a three-year period. METHODS: This cohort study included French-speaking community-dwelling older adults recruited in primary care practices in the province of Quebec and participating in the 'Étude sur la Santé des Ainés' (ESA)-Services study on the health of the elderly. Primary care practices were recruited through participating general practitioners (GPs) working full-time in the health administrative region. A stratified sample was comprised of various types of primary care practices (family medicine group, local community health services centers, primary care practices with less than 3 GPs, and with at least 3 GPs). In this study sample, 967 participants with scores ≥26 on the Mini Mental State Examination (MMSE) were included and followed for 3 years to study HR-QOL as a function of reported exercise at baseline and follow-up, controlling for study variables. Analyses were also carried out to study the effect of change in reported exercise at follow-up with respect to baseline and categorised as follows: no change, decrease in exercise and increase in exercise. The interaction terms area of residence socio-economic status*exercise and sex*exercise, were tested. RESULTS: Exercise at baseline did not significantly predict HR-QOL at follow-up when adjusting for all other study variables. Exercise at follow-up was cross-sectionally associated with follow-up HR-QOL. Participants reporting never exercising and those reporting a decrease in exercise reported a lower HR-QOL at follow-up, when controlling for all other study variables. There was no interaction between exercise and sex and socioeconomic status. CONCLUSIONS: For healthy ageing, maintaining and increasing physical activity throughout the years is necessary for improved HR-QOL. Past physical activity does not confer protection against future decline of HR-QOL. Future research should focus on potential moderating and mediating psycho-social barriers associated with exercising in older age populations.

Out-of-pocket costs and adherence to antihypertensive agents among older adults covered by the public drug insurance plan in Quebec.

OBJECTIVE: To evaluate the effect of patient out-of-pocket costs on adherence to antihypertensive agents (AHA) in community-dwelling older adults covered by the public drug insurance plan in Quebec. METHODS: This is a secondary analysis of data from the "Étude sur la santé des aînés" study (2005-2008) on community-dwelling older adults in Quebec aged 65 years and older (N=2,811). The final sample included 881 participants diagnosed with arterial hypertension and treated with AHA. Medication adherence was measured with the proportion of days covered over a 2-year follow-up period (<80% and ≥80%). Out-of-pocket costs for AHA, in Canadian dollars (CAD), at cohort entry were categorized as follows: $0, $0.01-$5.00, $5.01-$10.00, $10.01-$15.00 and $15.01-$36.00. Multivariable logistic regression models were constructed to study adherence to AHA as a function of out-of-pocket costs while controlling for several confounders. Models were also stratified by annual household income (<$15,000 CAD and ≥$15,000 CAD). RESULTS: In this study, 80.8% of participants were adherent to their AHA. Among participants reporting an annual household income <$15,000 CAD, those with an out-of-pocket cost of $10.01-$15.00 CAD were significantly less adherent to their AHA than those with no contribution (OR =0.175, 95% CI: 0.042-0.740). Among participants reporting an income of ≥$15,000 CAD, those with out-of-pocket costs of $0.01-$5.00 CAD (OR =0.194; 95% CI: 0.048-0.787), $5.01-$10.00 CAD (OR =0.146; 95% CI: 0.036-0.589), $10.01-$15.00 CAD (OR =0.192; 95% CI: 0.047-0.777) and $15.01-$36.00 CAD (OR =0.160, 95% CI: 0.039-0.655) were significantly less adherent to their AHA than participants with no contribution. CONCLUSION: Increased out-of-pocket costs are associated with non-adherence to AHA in older adults covered by a public drug insurance plan, more importantly in those reporting an annual household income ≥$15,000 CAD. A reduction in the amount of out-of-pocket costs and yearly maximum contribution for drugs may improve adherence to treatment.
