Access to and waiting time for psychiatrist services in a Canadian urban area: a study in real time

Barriers to Mental Health care in Canada Identified by Healthcare Providers: A Scoping Review

The mental health treatment gap remains wide across the world despite mental illness being a significant cause of disability globally. Both end-user and healthcare provider perspectives are critical to understanding barriers to mental healthcare and developing interventions. However, the views of providers are relatively understudied. In this review, we synthesized findings from current literature regarding providers' perspectives on barriers to mental healthcare in Canada. We searched Medline, PsycINFO, Embase, and CINAHL for eligible Canadian studies published since 2000. Analysis and quality assessment were conducted on the included studies. Of 4,773 reports screened, 29 moderate-high quality studies were reviewed. Five themes of barriers emerged: health systems availability and complexity (reported in 72% of the studies), work conditions (55%), training/education (52%), patient accessibility (41%), and identity-based sensitivity (17%). Common barriers included lack of resources, fragmented services, and gaps in continuing education. Interestingly, clinicians often cited confusion in determining the ideal service for patients due to an overwhelming number of potential services without clear descriptions. These five domains of barriers present a synthesized review of areas of improvement for mental healthcare spanning both patients and clinicians. Canadian mental health systems face a need to improve capacity, clinician training, and in particular service navigability and collaboration.

A Retrospective Cohort Analysis of Mental Health-Related Emergency Department Visits Among Veterans and Non-Veterans Residing in Ontario, Canada: Une analyse de cohorte rétrospective des visites au service d'urgence liées à la santé mentale parmi les vétérans et non-vétérans résidant en Ontario, Canada

OBJECTIVES

Emergency departments (EDs) are a vital part of healthcare systems, at times acting as a gateway to community-based mental health (MH) services. This may be particularly true for veterans of the Royal Canadian Mounted Police who were released prior to 2013 and the Canadian Armed Forces, as these individuals transition from federal to provincial healthcare coverage on release and may use EDs because of delays in obtaining a primary care provider. We aimed to estimate the hazard ratio (HR) of MH-related ED visits between veterans and non-veterans residing in Ontario, Canada: (1) overall; and by (2) sex; and (3) length of service.

METHODS

This retrospective cohort study used administrative healthcare data from 18,837 veterans and 75,348 age-, sex-, geography-, and income-matched non-veterans residing in Ontario, Canada between April 1, 2002, and March 31, 2020. Anderson-Gill regression models were used to estimate the HR of recurrent MH-related ED visits during the period of follow-up. Sex and length of service were used as stratification variables in the models.

RESULTS

Veterans had a higher adjusted HR (aHR) of MH-related ED visits than non-veterans (aHR, 1.97, 95% CI, 1.70 to 2.29). A stronger effect was observed among females (aHR, 3.29; 95% CI, 1.96 to 5.53) than males (aHR, 1.78; 95% CI, 1.57 to 2.01). Veterans who served for 5-9 years had a higher rate of use than non-veterans (aHR, 3.76; 95% CI, 2.34 to 6.02) while veterans who served for 30+ years had a lower rate compared to non-veterans (aHR, 0.60; 95% CI, 0.42 à 0.84).

CONCLUSIONS

Rates of MH-related ED visits are higher among veterans overall compared to members of the Ontario general population, but usage is influenced by sex and length of service. These findings indicate that certain subpopulations of veterans, including females and those with fewer years of service, may have greater acute mental healthcare needs and/or reduced access to primary mental healthcare.

N400 event-related brain potential index of semantic processing and two-year clinical outcomes in persons at high risk for psychosis: A longitudinal study

The N400 event-related brain potential (ERP) semantic priming effect reflects greater activation of contextually related versus unrelated concepts in long-term semantic memory. Deficits in this measure have been found in persons with schizophrenia and those at clinical high risk (CHR) for this disorder. In CHR patients, we previously found that these deficits predict poorer social functional outcomes after 1 year. In the present study, we tested whether these deficits predicted greater psychosis-spectrum symptom severity and functional impairment over 2 years. We measured N400 semantic priming effects at baseline in CHR patients (n = 47) who viewed prime words each followed by a related/unrelated target word at stimulus-onset asynchronies (SOAs) of 300 or 750 ms. We measured psychosis-spectrum symptoms using the Structured Interview for Prodromal Symptoms and role and social functioning with the Global Functioning: Role and Social scales, at baseline, 1 (n = 29) and 2 years (n = 25). There was a significant interaction between the N400 semantic priming effect at the 300-ms SOA and time on GF:Role scores, indicating that, contrary to expectations, smaller baseline N400 semantic priming effects were associated with more improvement in role functioning from baseline to Year 1, but baseline N400 priming effects did not predict role functioning at Year 2. N400 priming effects were not significantly associated with different trajectories in psychosis-spectrum symptoms or social functioning. Thus, CHR patients' N400 semantic priming effects did not predict clinical outcomes over 2 years, suggesting that this ERP measure may have greater value as a state or short-term prognostic neurophysiological biomarker.

An investigation of treatment return after psychological therapy for depression and anxiety

BACKGROUND

Some patients return for further psychological treatment in routine services, although it is unclear how common this is, as scarce research is available on this topic.

AIMS

To estimate the treatment return rate and describe the clinical characteristics of patients who return for anxiety and depression treatment.

METHOD

A large dataset (N=21,029) of routinely collected clinical data (2010-2015) from an English psychological therapy service was analysed using descriptive statistics.

RESULTS

The return rate for at least one additional treatment episode within 1-5 years was 13.7%. Furthermore, 14.5% of the total sessions provided by the service were delivered to treatment-returning patients. Of those who returned, 58.0% continued to show clinically significant depression and/or anxiety symptoms at the end of their first treatment, while 32.0% had experienced a demonstrable relapse before their second treatment.

CONCLUSIONS

This study estimates that approximately one in seven patients return to the same service for additional psychological treatment within 1-5 years. Multiple factors may influence the need for additional treatment, and this may have a major impact on service activity. Future research needs to further explore and better determine the characteristics of treatment returners, prioritise enhancement of first treatment recovery, and evaluate relapse prevention interventions.

Fatigue on Waking, Insomnia, and Workplace Relationship Problems May Help to Detect Suicidal Ideation among New Middle-Aged Primary Care Patients: A 6-Month Prospective Study in Japan

Signs of suicidal depression often go undetected in primary care settings. This study explored predictive factors for depression with suicidal ideation (DSI) among middle-aged primary care patients at 6 months after an initial clinic visit. New patients aged 35-64 years were recruited from internal medicine clinics in Japan. Baseline characteristics were elicited using self-administered and physician questionnaires. DSI was evaluated using the Zung Self-Rating Depression Scale and the Profile of Mood States at enrollment and 6 months later. Multiple logistic regression analysis was conducted to calculate adjusted odds ratios for DSI. Sensitivity, specificity, and likelihood ratios for associated factors were calculated. Among 387 patients, 13 (3.4%) were assessed as having DSI at 6 months. Adjusted for sex, age, and related factors, significant odds ratios for DSI were observed for "fatigue on waking ≥1/month" (7.90, 95% confidence intervals: 1.06-58.7), "fatigue on waking ≥1/week" (6.79, 1.02-45.1), "poor sleep status" (8.19, 1.05-63.8), and "relationship problems in the workplace" (4.24, 1.00-17.9). Fatigue on waking, sleep status, and workplace relationship problems may help predict DSI in primary care. Because the sample size in this investigation was small, further studies with larger samples are needed to confirm our findings.

Trends in Involuntary Psychiatric Hospitalization in British Columbia: Descriptive Analysis of Population-Based Linked Administrative Data from 2008 to 2018

INTRODUCTION

Involuntary psychiatric hospitalization occurs when someone with a serious mental disorder requires treatment without their consent. Trends vary globally, and currently, there is limited data on involuntary hospitalization in Canada. We examine involuntary hospitalization trends in British Columbia, Canada, and describe the social and clinical characteristics of people ages 15 and older who were involuntarily hospitalized between 2008/2009 and 2017/2018.

METHOD

We used population-based linked administrative data to examine and compare trends in involuntary and voluntary hospitalizations for mental and substance use disorders. We described patient characteristics (sex/gender, age, health authority, income, urbanity/rurality, and primary diagnosis) and tracked the count of involuntarily hospitalized people over time by diagnosis. Finally, we examined population-based prevalence over time by age and sex/gender.

RESULTS

Involuntary hospitalizations among British Columbians ages 15 and older rose from 14,195 to 23,531 (65.7%) between 2008/2009 and 2017/2018. Apprehensions involving police increased from 3,502 to 8,009 (128.7%). Meanwhile, voluntary admissions remained relatively stable, with a minimal increase from 17,651 in 2008/2009 to 17,751 in 2017/2018 (0.5%). The most common diagnosis for involuntary patients in 2017/2018 was mood disorders (25.1%), followed by schizophrenia (22.3%), and substance use disorders (18.8%). From 2008/2009 to 2017/2018, the greatest increase was observed for substance use disorders (139%). Over time, population-based prevalence increased most rapidly among women ages 15-24 (162%) and men ages 15-34 (81%) and 85 and older (106%).

CONCLUSION

Findings highlight the need to strengthen the voluntary care system for mental health and substance use, especially for younger adults, and people who use substances. They also signal a need for closer examination of the use of involuntary treatment for substance use disorders, as well as further research exploring forces driving police involvement and its implications.

Using novel methodology to estimate the prevalence of mental disorders in British Columbia, Canada

PURPOSE

A needs-based model of health systems planning uses a systematic estimate of service needs for a given population. Our objective was to derive annual prevalence estimates of specific mental disorders in the adult population of British Columbia, Canada and use a novel triangulation approach encompassing multiple data sources and stratifying these estimates by age, sex, and severity to inform Ministry partners, who commissioned this work.

METHODS

We performed systematic literature reviews and subsequent meta-analyses to derive an annual prevalence estimate for each mental disorder. We then generated age- and sex-specific estimates by triangulating published epidemiological studies, routinely collected province-wide health administrative data, and nationally representative health survey data sources. The age- and sex-specific estimates were further stratified by severity using the Global Burden of Disease severity distributions and published literature.

RESULTS

Anxiety disorders had the highest annual prevalence estimates (6.93%), followed by depressive disorders (6.42%). All other mental disorders had an annual prevalence of less than 1%. Prevalence estimates were consistently higher in younger age groups. Depressive disorders, anxiety disorders, and eating disorders were higher in women, while estimates for bipolar disorders, schizophrenia, and ADHD were slightly higher in men in younger age groups.

CONCLUSION

We generated robust annual prevalence estimates stratified by age, sex, and severity using a triangulation approach. Variation by age, sex, and severity implies that these factors need to be considered when planning for mental health services. Our approach is replicable and can be used as a model for needs-based planning in other jurisdictions.

The relationship between outpatient service use and emergency department visits among people treated for mental and substance use disorders: analysis of population-based administrative data in British Columbia, Canada

Background

Research findings on the association between outpatient service use and emergency department (ED) visits for mental and substance use disorders (MSUDs) are mixed and may differ by disorder type.

Methods

We used population-based linked administrative data in British Columbia, Canada to examine associations between outpatient primary care and psychiatry service use and ED visits among people ages 15 and older, comparing across people treated for three disorder categories: common mental disorders (MDs) (depressive, anxiety, and/or post-traumatic stress disorders), serious MDs (schizophrenia spectrum and/or bipolar disorders), and substance use disorders (SUDs) in 2016/7. We used hurdle models to examine the association between outpatient service use and odds of any ED visit for MSUDs as well count of ED visits for MSUDs, stratified by cohort in 2017/8.

Results

Having had one or more MSUD-related primary care visit was associated with lower odds of any ED visit among people treated for common MDs and SUDs but not people treated for serious MDs. Continuity of primary care was associated with slightly lower ED use in all cohorts. One or more outpatient psychiatrist visits was associated with lower odds of ED visits among people treated for serious MDs and SUDs, but not among people with common MDs.

Conclusion

Findings highlight the importance of expanded access to outpatient specialist mental health services, particularly for people with serious MDs and SUDs, and collaborative models that can support primary care providers treating people with MSUDs.

N400 event-related brain potential and functional outcome in persons at clinical high risk for psychosis: A longitudinal study

BACKGROUND

The N400 event-related brain potential (ERP) semantic priming effect is thought to reflect activation by meaningful stimuli of related concepts in semantic memory and has been found to be deficient in schizophrenia. We tested the hypothesis that, among individuals at clinical high risk (CHR) for psychosis, N400 semantic priming deficits predict worse symptomatic and functional outcomes after one year.

METHODS

We measured N400 semantic priming at baseline in CHR patients (n = 47) and healthy control participants (n = 25) who viewed prime words each followed by a related or unrelated target word, at stimulus-onset asynchronies (SOAs) of 300 or 750 ms. We measured patients' psychosis-like symptoms with the Scale of Prodromal Symptoms (SOPS) Positive subscale, and academic/occupational and social functioning with the Global Functioning (GF):Role and Social scales, respectively, at baseline and one-year follow-up (n = 29).

RESULTS

CHR patients exhibited less N400 semantic priming than controls across SOAs; planned contrasts indicated this difference was significant at the 750-ms but not the 300-ms SOA. In patients, reduced N400 semantic priming at the 750-ms SOA was associated with lower GF:Social scores at follow-up, and greater GF:Social decrements from baseline to follow-up. Patients' N400 semantic priming was not associated with SOPS Positive or GF:Role scores at follow-up, or change in these from baseline to follow-up.

CONCLUSIONS

In CHR patients, reduced N400 semantic priming at baseline predicted worse social functioning after one year, and greater decline in social functioning over this period. Thus, the N400 may be a useful prognostic biomarker of real-world functional outcome in CHR patients.

Emergency department use for mental and substance use disorders: descriptive analysis of population-based, linked administrative data in British Columbia, Canada

OBJECTIVES

Information on emergency department (ED) visits for mental and substance use disorders (MSUDs) is important for planning services but has not been explored in British Columbia (BC), Canada. We describe all MSUD ED visits for people ages 15 and older in the province of BC in 2017/2018 and document trends in MSUD ED visits between 2007/2008 and 2017/2018 by disorder group.

DESIGN

Population-based linked administrative data comprised of ED records and physician billings capturing all MSUD ED visits in BC.

SETTING

BC is Canada's westernmost province with a population of approximately 5 million. Permanent residents receive first-dollar coverage for all medically necessary services provided by licensed physicians or in hospitals, including ED services.

POPULATION

All people age >15 with MSUD ED visits during the study period.

MEASURES

All claims with a service location in the ED or corresponding to fee items billed only in the ED were examined alongside ED visits reported through a national reporting system. Patient characteristics (sex/gender, age, location of residence, income, treated disorders and comorbidities) and previous outpatient service use for all ED visits by visit diagnosis are also described.

RESULTS

A total of 72 363 people made 134 063 visits to the ED in 2017/2018 for needs related to MSUD. MSUD ED visits have increased since 2010, particularly visits for substance use and anxiety disorders. People with more frequent visits were more likely to be male, on public prescription drug plans for income assistance, prescribed psychiatric medications, and living in lower-income neighbourhoods. They used more community-based primary care and psychiatry services and had lower continuity of primary care.

CONCLUSIONS

MSUD ED visits are substantial and growing in BC. Findings underscore a need to strengthen and target community healthcare services and adequately resource and support EDs to manage growing patient populations.

Wartezeiten auf einen Psychotherapieplatz vor und nach der Psychotherapiestrukturreform

Hintergrund und Fragestellung

Die Psychotherapiestrukturreform im Jahr 2017 verfolgte u. a. das Ziel, die Wartezeiten auf Psychotherapien zu verringern. Diese Studie ging der Frage nach, ob dieses Ziel erreicht wurde.

Methoden

Psychotherapiepraxen aus 7 Bundesländern entnahmen ihren Akten die Daten für Erstkontakt, Erstgespräch und Behandlungsbeginn. Der Vergleich der Wartezeiten auf ein Erstgespräch und auf den Beginn der Behandlung vor vs. nach der Reform erfolgte mithilfe von Kaplan-Meier-Kurven und stratifizierten Log-Rank-Tests.

Ergebnis

Akten von 1548 Patienten aus 9 Praxen wurden ausgewertet. Die durchschnittliche Wartezeit auf ein Erstgespräch lag sowohl vor als auch nach der Reform bei 3 Wochen (p = 0,20). Die Zeit zwischen der Anmeldung und dem Behandlungsbeginn erhöhte sich von durchschnittlich 18 auf 20 Wochen, wobei nach der Reform v. a. die sehr kurzen Wartezeiten (<10 Wochen) abnahmen (p = 0,0004).

Diskussion

Die in den Praxen dokumentierten Daten liefern keine Anhaltspunkte dafür, dass sich die Wartezeit auf Erstgespräche bei Psychotherapeuten verkürzt hat. Das Warten auf einen Psychotherapieplatz scheint insgesamt etwas länger geworden zu sein, sodass in dieser Hinsicht keine Verbesserung der Versorgung durch die Reform festgestellt werden konnte.

A retrospective records study of patterns in mental health and criminal justice service use by people found not criminally responsible on account of mental disorder

BACKGROUND

While the presence or absence of previous healthcare and criminal justice system (CJS) contacts in the histories of mentally ill offenders has been well-studied, the frequency of these contacts and when they occur in the period leading up to an index criminal event has received less research attention.

AIMS

To explore patterns of healthcare and CJS use in the year prior to a criminal act leading to a Not Criminally Responsible on Account of Mental Disorder (NCRMD) finding in Canada.

METHODS

In this 3-year retrospective records study, the case files of all patients newly admitted to the British Columbia forensic psychiatric system after a finding of NCRMD between 1st July 2012 and 31st July 2015 were reviewed. Data were extracted on healthcare and CJS use for the 12 months before the act leading to the NCRMD finding. Time-based descriptive statistics and two-step cluster analysis were used to investigate service use patterns.

RESULTS

Among 94 eligible patients, only four had no service contacts in the year leading up to the index event, leaving 90 in the cohort for further analysis. On average, these 90 patients had seven contacts with health or criminal justice services in the year prior to the index offence. Cluster analysis revealed a high healthcare pathway group who had had many healthcare and few CJS contacts; a limited service user group who had had few contacts of any kind and a heavy service user group who had had a high volume of contacts with both types of service providers.

CONCLUSIONS

The different patterns of patient contact prior to the index event imply that each practitioner-type has distinct and temporally relevant opportunities to provide preventative interventions to their patients or user groups.

Incidence of Access to Ambulatory Mental Health Care Prior to a Psychiatric Emergency Department Visit Among Adults in Ontario, 2010-2018

IMPORTANCE

Psychiatric emergency department (ED) visits may be avoidable if individuals have access to adequate outpatient care, but the extent to which individuals use the ED itself as a key point of access is largely unknown.

OBJECTIVE

To describe the extent to which the ED is a first point of contact for mental health care among adults, and identify key factors associated with this outcome.

DESIGN, SETTING, AND PARTICIPANTS

This cohort study was conducted from 2010 to 2018 in Ontario, Canada. Using health care administrative data, all individuals aged 16 years and older with an incident psychiatric ED visit were included. Statistical analysis was performed from September 2019 to February 2021.

MAIN OUTCOMES AND MEASURES

The primary outcome was no outpatient mental health or addictions contact in the 2 years preceding the incident ED visit. The study also measured predisposing (age, sex, immigrant status, comorbidity), enabling (neighborhood income, rurality, continuity of primary care), and need factors (diagnosis from incident ED visit) associated with the so-called first-contact ED visits, generating adjusted odds ratios (aORs) and 95% CIs.

RESULTS

The cohort included 659 084 patients who visited the ED. Among these patients, 340 354 were female individuals (51.6%), and the mean (SD) age was 39.1 (18.5) years. The incident ED visit was a first contact for 298 924 individuals (45.4%). Patients who had increased odds of first-contact ED visits included older individuals (aged 65-84 years vs 16-24 years; aOR, 1.13; 95% CI, 1.12-1.14), male individuals (aOR, 1.14; 95% CI, 1.13-1.15), immigrants (eg, economic class immigrant vs nonimmigrant status: aOR, 1.20; 95% CI, 1.18-1.21), rural residents (aOR, 1.21; 95% CI, 1.20-1.21), and in those with minimal primary care (aOR, 1.68; 95% CI, 1.67-1.69). All diagnoses had a higher likelihood of first-contact ED visits than mood disorders, particularly substance and alcohol use disorders (aOR, 1.66; 95% CI, 1.65-1.68).

CONCLUSIONS AND RELEVANCE

This study's results suggest that nearly half of incident psychiatric ED visits were first-contact visits, which may be avoidable. Targeted efforts to improve outpatient access should focus on populations with risk factors for first-contact ED presentations, including men, older adults, rural residents, those with poor primary care connectivity, and those with substance-related diagnoses.

Characterizing Family Physicians Who Refer to Telepsychiatry in Ontario

INTRODUCTION

Telepsychiatry can improve access to psychiatric services for those who otherwise cannot easily access care. Family physicians are gatekeepers to specialized care in Ontario, so it is essential to understand predictors relating to referrals to telepsychiatry to better plan services and increase telepsychiatry adoption.

METHODS

This study used an annual retrospective cross-sectional study design to compare physicians who referred their patients to telepsychiatry each year from fiscal year (FY) 2008 to FY 2016. A 1-year (FY 2016) comparison of family physicians who referred to telepsychiatry (FPTs) compared to family physicians who did not refer to telepsychiatry (FPNTs) matched (1:2) by region was also conducted. Finally, we used statistical modeling to understand the predictors of referring to telepsychiatry among physicians.

RESULTS

Between FY 2008 and FY 2016, the number of patients receiving telepsychiatry increased from 925 visits to 13,825 visits. Thirty-two percent of Ontario primary care physicians referred to telepsychiatry in 2016. Several characteristics were notably different between FPTs and FPNTs: FPTs were more likely to be from a residence with less than 10,000 people, to have more nurse practitioners in the practice, and to be from a family health team than FPNTs. Rostered patients of FPTs were more likely to reside in rural areas, have more clinical complexity, and to utilize more mental health services compared to FPNTs.

CONCLUSIONS

There has been an increase in the use of telepsychiatry by patients and family physicians over the study period, although there remains opportunity for significant growth. Family physicians who live in rural areas, are part of an FHT, have more NPs, with more rural and complex patients were more likely to refer to telepsychiatry. As recent pro-telemedicine policies support the growth of telepsychiatry, this study will serve as an important baseline.

Developing a Framework of Integrated Competencies for Adaptive Expertise in Integrated Physical and Mental Health Care

Phenomenon: Despite the emergence of the integrated care (IC) model, IC is variably taught and is challenged by current siloed competency domains. This study aimed to define IC competencies spanning multiple competency domains. Approach: Iterative facilitated discussions were conducted at a half-day education retreat with 25 key informants including clinician educators and education scientists. Seven one-on-one semistructured interviews were subsequently conducted with different interprofessional providers in IC settings within a Canadian context. Data collection grounded in patient cases with a physical illness and concurrent mental illness (medical psychiatry) were used to elicit identification of complex patient needs and the key medical psychiatry knowledge and skills required to address these needs. A thematic analysis of transcripts was performed using constant comparison to iteratively identify themes. Findings: Participants described 4 broad competency domains necessary for expertise in IC: (a) extensive integrated knowledge of biopsychosocial aspects of disease, systems of care, and social determinants of care; (b) skills to establish a longitudinal alliance with the patient and functional relationships with colleagues; (c) constructing a comprehensive understanding of individual patients' complex needs and how these can be met within their health and social systems; and (d) the ability to effectively meet the patient's needs using IC models. These 4 domains were linked by an overarching philosophy of care encompassing key enabling attitudes such as proactively pursuing depth to understand patient and system complexity while maintaining a patient-centered approach. Insights: The study addresses how development of IC expertise can be fostered by integration of individual IC competency domains. The findings align with previous research suggesting that competencies from existing frameworks are being enacted jointly in expert capabilities to meet the complex needs of patients, in this case with comorbid physical and mental health concerns.

Closed for Business? Using a Mixture Model to Explore the Supply of Psychiatric Care for New Patients

OBJECTIVE

To investigate the degree to which psychiatrists are accessible to new outpatients and the factors that predict whether psychiatrists will see new outpatients.

METHODS

We used administrative health data on all practicing full-time psychiatrists in Ontario, Canada, over a 5-year period (2009-2010 to 2013-2014). We used a regression model to estimate the number of new outpatients seen, accounting for case mix, outpatient volume, and psychiatrist practice characteristics.

RESULTS

Approximately 10% of full-time psychiatrists are seeing 1 or fewer new outpatients per month, and another 10% are seeing between 1 and 2 new outpatients per month. Our model identified psychiatrists in 3 distinct practice styles. One practice style (representing 29% of psychiatrists), on average, saw fewer than 2 new outpatients per month and 69 unique outpatients annually. Relative to other practice styles, they tended to see fewer patients with a previous psychiatric hospitalization and fewer patients who lived in lower income neighbourhoods.

CONCLUSIONS

Nearly 1 in 3 full-time psychiatrists in Ontario see very few new outpatients. This has implications for access to care, particularly for outpatients with newly diagnosed mental illness. It also highlights the continued need to address access issues by assessing the role of psychiatrists within the Canadian health care system.

Sociodemographic Variation in Increasing Needs for Mental Health Services among Canadian Adults from 2002 to 2012

BACKGROUND

Numerous countries have developed public health programs and restructured mental health service delivery to alleviate the growing burden of mental illness. These initiatives address increased needs for mental health services, as individuals become better-informed and more open-minded concerning psychiatric symptoms and mental health care. This study aimed to investigate how needs for mental health services have increased among Canadian adults in recent years, and how needs may differ across different sociodemographic groups.

DATA AND METHODS

The study compared data from the Canadian Community Health Survey for 2002 (n = 31,744), and 2012 (n = 23,319), including respondents 18 years old and over. Needs for mental health services were defined in terms of major depression (MD), psychological distress (PD), consultations with various health professionals, and by objective and perceived unmet needs (PUNs). Odds ratios were estimated using hierarchical logistic regressions, controlling for sociodemographic variables.

RESULTS

Overall, needs for mental health services were higher in 2012 than in 2002, with increases affecting some sociodemographic groups more than others. MD and PD grew disproportionately among lower income individuals and women. Individuals hospitalized for psychiatric reasons, those unemployed, and men accounted for most of the increase in healthcare consultations. PUNs were more pronounced among unemployed individuals, and respondents born in Canada.

CONCLUSION

Findings from this study confirm the increasing and need for mental health services in Canada, and suggest that public health campaigns should be geared to specific sociodemographic groups.

Transcranial Magnetic Stimulation for Adolescent Depression

Adolescent depression is a substantial global public health problem that contributes to academic failure, occupational impairment, deficits in social functioning, substance use disorders, teen pregnancy, and completed suicide. Existing treatment options often have suboptimal results and uncertain safety profiles. Transcranial magnetic stimulation may be a promising, brain-based intervention for adolescents with depression. Existing work has methodological weaknesses, and larger, neurodevelopmentally informed studies are urgently needed. Treatment with transcranial magnetic stimulation may modulate cortical GABAergic and glutamatergic imbalances. Future study will inform dosing approaches for TMS based on GABAergic and glutamatergic biomarkers.

Models of Concurrent Disorder Service: Policy, Coordination, and Access to Care

Background: Societal capacity to address the service needs of persons with concurrent mental health and substance-use disorders has historically been challenging given a traditionally siloed approach to mental health and substance-use care. As different approaches to care for persons with concurrent disorders emerge, a limited understanding of current models prevails. The goal of this paper is to explore these challenges along with promising models of coordinated care across Canadian provinces. Materials and methods: A scoping review of policies, service coordination and access issues was undertaken involving a review of the formal and gray literature from 2000 to 2018. The scoping review was triangulated by an analysis of provincial auditor general reports. Results: Models of concurrent disorders service were found to have evolved unevenly. Challenges related to the implementation of models of collaborative care and local networks that foster service coordination and policy accountability were found to inhibit integrated care. Conclusion: Emergent models of coordinated care were found to include collaborative care, regional networks with centralized access to care, clinical information-sharing, cross-training, improved scope of care to include psychologists and alignment of physician incentives with patient needs to better support patient care.

A systematic review and meta-analysis on the efficacy of Internet-delivered behavioral activation

BACKGROUND

Behavioral activation (BA) is an evidence-based treatment for depression which has attracted interest and started to accumulate evidence for other conditions when delivered face-to-face. Due to its parsimoniousness, it is suitable to be delivered via the Internet. The goal of this systematic review and meta-analysis was to examine evidence from randomized controlled trials (RCTs) to determine the efficacy of Internet-based BA and assess the quality of this evidence.

METHODS

Studies were identified from electronic databases (EMBASE, ISI Web of Knowledge, Medline, CINHAL, PsychINFO, Cochrane) and reference lists of included studies. Two reviewers independently screened articles for inclusion and extracted data. They assessed the quality of evidence for each outcome using The Grading of Recommendations Assessment, Development and Evaluation framework.

RESULTS

Nine RCTs on different forms of depression were included with 2157 adult participants. Random effects meta-analyses showed that in non-clinical settings, guided Internet-based BA was non-inferior to other forms of behavioral therapy and mindfulness (mainly very low to low quality evidence) and superior to physical activity (very low quality evidence), psychoeducation/treatment as usual (moderate quality evidence) and waitlist (low quality evidence) at reducing depression and anxiety outcomes at post-treatment and short follow-up.

LIMITATIONS

The poor quality of some of the findings means that results should be cautiously interpreted.

CONCLUSIONS

Evidence for the efficacy of Internet-based BA as a treatment for depression is promising. However, high quality studies with longer follow-ups are needed to increase confidence in findings and determine its efficacy in clinical settings and other conditions.

The alignment imperative in curriculum renewal

RATIONALE

There are perennial calls for MD curricula to reform in order to meet the changing needs of students, patients, and society. And yet, efforts at renewal have also been suggested to have minimal impact on the pedagogy and outcomes of medical education. One reason may be misalignment between the components of the curriculum during design and implementation. The University of Toronto MD program recently renewed its undergraduate preclinical Foundations curriculum. Mindful of the pitfalls of misalignment, the renewal process focused deliberately on alignment between the various components of the curriculum: instructional methods, student assessment, faculty development, and the larger purpose of serving students and society.

INNOVATION

Educational evidence was used to drive the alignment process which resulted in three major changes. First, we created a spiral curriculum centered on 72 virtual patient cases designed to integrate content and prepare students for clinical learning. Second, we introduced a novel medical psychiatry component to address a core societal need in mental health. This exposed students early to experiences of complexity, ambiguity, and integrated patient care. Lastly, a shift to assessment for learning and programmatic assessment was designed and implemented concurrently to reinforce the pedagogy of the curriculum. Synchronous faculty development was developed for the new roles required of faculty.

CONCLUSIONS

Early program evaluation shows alignment of these curricular components requires ongoing attention and resources in order to be successful. The potential benefits of this alignment are well prepared students who can meet the needs of their patients and society in an increasingly complex health system.

Optimizing Electronic Consultation Between Primary Care Providers and Psychiatrists: Mixed-Methods Study

Background

The use of electronic consultation (e-consult) between primary care providers (PCPs) and psychiatrists has potential, given the high prevalence of mental health issues in primary care and problematic access to specialist care. Utilization and uptake, however, appears to be lower than would be expected.

Objective

This study aimed to examine actual utilization of e-consult between PCPs and psychiatrists and investigate the perceptions of PCPs about this form of psychiatric advice to inform how to optimize the utility and thereby the uptake of this service.

Methods

In this mixed-methods study, we conducted a chart review of psychiatry e-consults (N=37) over 2 platforms during early implementation in Ontario, Canada, as well as 3 group interviews and 1 individual interview with PCPs (N=10) with variable experience levels and from a range of practice settings. The chart review assessed response times and referral content including the type of request, referral attachments, and consultant responses. Interviews explored the perceptions of the PCPs about the uses and barriers of psychiatry e-consult. Thematic content analysis of interview data identified common themes as well as themes unique to different provider profiles (eg, experienced PCPs vs new PCPs and rural vs urban practice). On the basis of interpretation of the quantitative and qualitative findings, we developed recommendations for the optimization of psychiatry e-consultation services.

Results

During the study period, psychiatry e-consults comprised 3.66% (49/1339) of all e-consults submitted on the studied platforms. Among the e-consults reviewed, different psychiatric diagnoses were represented: 70% of requests (26/37) queried about medication safety or side effects, whereas 59% (22/37) asked about psychiatric symptom management. Moreover, 81% (30/37) of e-consults were answered within 24 hours, and 65% (24/37) were addressed in a single exchange. Themes from the interview data included psychiatry having a complexity that differentiates it from other specialties and may limit the utility of e-consult, other than for psychopharmacology advice. Variability in awareness exists in the way e-consultation could be used in psychiatry, with new PCPs feeling unsure about the appropriateness of a question. In general, new PCPs and PCPs practicing in rural areas were more receptive to psychiatry e-consult. PCPs viewed e-consult as an opportunity to collaborate and desired that it be integrated with other available services. Recommendations include the need for appropriate specialist staffing to address a wide range of requests, adequate education to referrers regarding the use of psychiatry e-consult, and the need to integrate psychiatry e-consult with other geographically relevant services, given the complexity of psychiatric issues.

Conclusions

E-consult is a viable and timely way for PCPs to get much-needed psychiatric advice. For optimizing its utility and uptake, e-consult needs to be integrated into reliable care pathways with adequate referrer and consultant preparation.

Scoping review protocol: education initiatives for medical psychiatry collaborative care

INTRODUCTION

The collaborative care model is an approach providing care to those with mental health and addictions disorders in the primary care setting. There is a robust evidence base demonstrating its clinical and cost-effectiveness in comparison with usual care; however, the transitioning to this new paradigm of care has been difficult. While there are efforts to train and prepare healthcare professionals, not much is known about the current state of collaborative care training programmes. The objective of this scoping review is to understand how widespread these collaborative care education initiatives are, how they are implemented and their impacts.

METHODS AND ANALYSIS

The scoping review methodology uses the established review methodology by Arksey and O'Malley. The search strategy was developed by a medical librarian and will be applied in eight different databases spanning multiple disciplines. A two-stage screening process consisting of a title and abstract scan and a full-text review will be used to determine the eligibility of articles. To be included, articles must report on an existing collaborative care education initiative for healthcare providers. All articles will be independently assessed for eligibility by pairs of reviewers, and all eligible articles will be abstracted and charted in duplicate using a standardised form. The extracted data will undergo a 'narrative review' or a descriptive analysis of the contextual or process-oriented data and simple quantitative analysis using descriptive statistics.

ETHICS AND DISSEMINATION

Research ethics approval is not required for this scoping review. The results of this scoping review will inform the development of a collaborative care training initiative emerging from the Medical Psychiatry Alliance, a four-institution philanthropic partnership in Ontario, Canada. The results will also be presented at relevant national and international conferences and published in a peer-reviewed journal.

How Much Do Mental Health and Substance Use/Addiction Affect Use of General Medical Services? Extent of Use, Reason for Use, and Associated Costs

OBJECTIVE

To measure service use and costs associated with health care for patients with mental health (MH) and substance use/addiction (SA) problems.

METHODS

A 5-year cross-sectional study (2007-2012) of administrative health care data was conducted (average annual sample size = 123,235 adults aged >18 years who had a valid Ontario health care number and used at least 1 service during the year; 55% female). We assessed average annual use of primary care, emergency departments and hospitals, and overall health care costs for patients identified as having MH only, SA only, co-occurring MH and SA problems (MH+SA), and no MH and/or SA (MH/SA) problems. Total visits/admissions and total non-MH/SA visits (i.e., excluding MH/SA visits) were regressed separately on MH, SA, and MH+SA cases compared to non-MH/SA cases using the 2011-2012 sample ( N = 123,331), controlling for age and sex.

RESULTS

Compared to non-MH/SA patients, MH/SA patients were significantly ( P < 0.001) more likely to visit primary care physicians (1.82 times as many visits for MH-only patients, 4.24 for SA, and 5.59 for MH+SA), use emergency departments (odds, 1.53 [MH], 3.79 [SA], 5.94 [MH+SA]), and be hospitalized (odds, 1.59 [MH], 4.10 [SA], 7.82 [MH+SA]). MH/SA patients were also significantly more likely than non-MH/SA patients to have non-MH/SA-related visits and accounted for 20% of the sample but over 30% of health care costs.

CONCLUSIONS

MH and SA are core issues for all health care settings. MH/SA patients use more services overall and for non-MH/SA issues, with especially high use and costs for MH+SA patients.

Changes in Characteristics and Practice Patterns of Ontario Psychiatrists

OBJECTIVE

The objective of this study was to evaluate the changes in demographic, geographic, and practice characteristics of all Ontario psychiatrists between 2003 and 2013 and their implication for access to psychiatrists.

METHODS

We included all psychiatrists who were clinically active in Ontario in any year from 2003 to 2013. For each psychiatrist, we reported age, sex, years since medical school graduation, geographic practice region, and practice characteristics such as total number of inpatients, outpatients, and outpatient visit frequencies.

RESULTS

In 2013, there were 2070 psychiatrists, with nearly half (47%) more than 30 years since medical school graduation. Female psychiatrists comprised 41% of all psychiatrists in 2013 but 56% of all psychiatrists within 15 years of medical school graduation. Between 2003 and 2013, there was a 17% increase in the total number of psychiatrists, with the largest growth in psychiatrists occurring in the group more than 30 years from medical school graduation. Over these 11 years, the mean (SD) number of unique outpatients seen by a psychiatrist annually increased from 208 (228) to 249 (275) (19.5%; P = 0.001), with male psychiatrists, on average, seeing more outpatients annually than female psychiatrists.

CONCLUSION

The number of outpatients seen by psychiatrists is slowly increasing. However, the large proportion of aging psychiatrists, the high concentration of psychiatrists in urban settings, and the increase in the number of female psychiatrists with smaller practices suggest that without radical changes to the way psychiatrists practice, access to psychiatrists will remain a challenge in Ontario.

How Often Do Individuals with Major Depression Receive Minimally Adequate Treatment? A Population-Based, Data Linkage Study

Objective:

Depression is usually treated with antidepressants, psychotherapy, or both. In this study, we examined the extent to which individuals with depression receive minimally adequate treatment with regard to the use of antidepressants and psychotherapy.

Method:

Using population-based administrative data, we identified individuals with inpatient or outpatient diagnoses of depression and tracked their use of publicly funded mental health services within a 12-month period. We used mixed-effects logistic regression to assess the influence of patient-level characteristics and physician-level variations on the receipt of minimally adequate treatment.

Results:

A total of 108 101 individuals, predominantly women (65%) and urban residents (89%), were diagnosed with depression in 2010–2011. Of these, 13% received minimally adequate counseling/psychotherapy with higher proportions observed among men, younger individuals, and urban residents. In contrast, there were more who received minimally adequate antidepressant therapy (48%), with women, older individuals, and rural residents having the highest proportions. Overall, about 53% received either type of treatment, and the pattern of use was similar to that of antidepressant therapy. Mixed-effects logistic regression results indicate that these factors remain independent predictors of the receipt of minimally adequate depression care. Significant practice variations also exist, which determine patients’ receipt of minimally adequate care, particularly with respect to counseling or psychotherapy.

Conclusions:

Only about half of those with depression receive either minimally adequate counseling/psychotherapy or minimally adequate antidepressant therapy. Disparities also persist, affecting mostly men and younger individuals. A multifactorial approach is needed to improve access to and reduce variations in receipt of minimally adequate depression care.

Adequacy of Mental Health Services for HIV-Positive Patients with Depression: Ontario HIV Treatment Network Cohort Study

Background

Major depression can profoundly impact clinical and quality-of-life outcomes of people living with HIV, and this disease is underdiagnosed and undertreated in many HIV-positive individuals. Here, we describe the prevalence of publicly funded primary and secondary mental health service use and antidepressant use, as well as mental health care for depression in accordance with existing Canadian guidelines for HIV-positive patients with depression in Ontario, Canada.

Methods

We conducted a prospective cohort study linking data from the Ontario HIV Treatment Network Cohort Study with administrative health databases in the province of Ontario, Canada. Current depression was assessed using the Center for Epidemiologic Depression Scale or the Kessler Psychological Distress Scale. Multivariable regressions were used to characterize prevalence outcomes.

Results

Of 990 HIV-positive patients with depression, 493 (50%) patients used mental health services; 182 (18%) used primary services (general practitioners); 176 (18%) used secondary services (psychiatrists); and 135 (14%) used both. Antidepressants were used by 407 (39%) patients. Patients who identified as gay, lesbian, or bisexual, as having low income or educational attainment, or as non-native English speakers or immigrants to Canada were less likely to obtain care. Of 493 patients using mental health services, 250 (51%) received mental health care for depression in accordance with existing Canadian guidelines.

Conclusions

Our results showed gaps in delivering publicly funded mental health services to depressed HIV-positive patients and identified unequal access to these services, particularly among vulnerable groups. More effective mental health policies and better access to mental health services are required to address HIV-positive patient needs and reduce depression’s impact on their lives.

Choosing Wisely? Let's Start with Working Wisely

There is an increasing emphasis on quality and, relatedly, cost-effectiveness as it relates to the delivery of health care. Choosing Wisely is an initiative adopted by numerous specialties with the goal of starting a dialogue about efficient use of health care resources. People need to be able to access care to have an opportunity to choose wisely. There is a considerable amount of evidence that access to care is poor for specialty mental health care, particularly access to psychiatrists. Consequently, we suggest that psychiatrists and the broader mental health system need to consider working wisely, and in our paper outline key issues (for example, implementation of wait times and objective measures of need in a centralized referral management system; incorporation of performance indicators with longitudinal monitoring for continuous quality improvement) that need to be addressed to develop a mental health system that would allow people to access care to choose wisely.

Moving Out of the Office: Removing Barriers to Access to Psychiatrists

Our paper offers a perspective on barriers to access to psychiatric care. Research shows that access depends not simply on the total number of trained specialists but also on their kind of practice. In some large cities, some practitioners follow a small number of patients in long-term psychotherapy, a practice supported by government insurance, which places no limits on the number of sessions or treatment duration. The problem is that long-term psychotherapy, despite a rich tradition in psychiatry, is not an evidence-based treatment. This review recommends a model in which psychiatrists spend more time in consultation with primary care professionals, in acute care for patients with severe mental illness, and in briefer, more cost-effective forms of psychotherapy.

Consulting psychiatry within an integrated primary care model

After implementation of an integrated consulting psychiatry model and psychology services within primary care at a federally qualified health center, patients have increased access to needed mental health services, and primary care clinicians receive the support and collaboration needed to meet the psychiatric needs of the population.

The mood disorders association of british columbia psychiatric urgent care program: a preliminary evaluation of a suggested alternative model of outpatient psychiatric care

OBJECTIVE

To describe an alternative model of psychiatric outpatient care for patients with mood and anxiety disorders (the Mood Disorders Association of British Columbia Psychiatric Urgent Care Program or the MDA Program) using group medical visits (GMV) and (or) email communications in lieu of individual follow-up appointments.

METHOD

Annual costs of the MDA Program were compared with average costs of private psychiatrists offering outpatient care and patients being treated in a mental health centre. In addition, questionnaires as to patient satisfaction with the MDA Program intake, GMV experience, and family physician satisfaction with the MDA Program were administered.

RESULTS

The MDA Program model of care is significantly more cost effective than individual psychiatric outpatient care or health authority mental health centre care for patients with moderate or severe illness. Patients and family physicians were very satisfied with the model of care and GMVs offered.

CONCLUSIONS

The MDA Program model of care appears to be efficient and cost-effective, and patients and referring physicians appear satisfied with the care offered in this program.

Do patients really prefer individual outpatient follow-up visits, compared with group medical visits?

OBJECTIVE

Access to outpatient psychiatric care remains problematic in Canada. We have been using group medical visits (GMV) to treat psychiatric outpatients with mood and anxiety disorders. Our study aimed to show that patients are similarly satisfied with GMV and individual psychiatric treatment, hence the concern that patients truly prefer individual treatment may be unfounded.

METHOD

Our study compared patient satisfaction in people who have had previous individual psychiatric care and are now receiving GMV to determine whether there is a treatment preference.

RESULTS

Questionnaire data were analyzed using repeated measures ANOVA. The ANOVAs showed no differences in patients' experiences with individual treatment, compared with GMV. In addition, we found when asked directly, most patients preferred GMV or had no treatment preference.

CONCLUSIONS

These findings indicate that patients' perspectives of individual psychiatric treatment and GMV are roughly equal. This suggests that the method of GMV deserves further study and comparison with other clinical models of psychiatric outpatient treatment.

Access to the US Department of Veterans Affairs health system: self-reported barriers to care among returnees of Operations Enduring Freedom and Iraqi Freedom

BACKGROUND

The U.S. Department of Veterans Affairs (VA) implemented the Polytrauma System of Care to meet the health care needs of military and veterans with multiple injuries returning from combat operations in Afghanistan and Iraq. Studies are needed to systematically assess barriers to use of comprehensive and exclusive VA healthcare services from the perspective of veterans with polytrauma and with other complex health outcomes following their service in Afghanistan and Iraq. These perspectives can inform policy with regard to the optimal delivery of care to returning veterans.

METHODS

We studied combat veterans (n = 359) from two polytrauma rehabilitation centers using structured clinical interviews and qualitative open-ended questions, augmented with data collected from electronic health records. Our outcomes included several measures of exclusive utilization of VA care with our primary exposure as reported access barriers to care.

RESULTS

Nearly two thirds of the veterans reported one or more barriers to their exclusive use of VA healthcare services. These barriers predicted differences in exclusive use of VA healthcare services. Experiencing any barriers doubled the returnees' odds of not using VA exclusively, the geographic distance to VA barrier resulted in a 7 fold increase in the returnees odds of not using VA, and reporting a wait time barrier doubled the returnee's odds of not using VA. There were no striking differences in access barriers for veterans with polytrauma compared to other returning veterans, suggesting the barriers may be uniform barriers that predict differences in using the VA exclusively for health care.

CONCLUSIONS

This study provides an initial description of utilization of VA polytrauma rehabilitation and other medical care for veteran returnees from all military services who were involved in combat operations in Afghanistan or Iraq. Our findings indicate that these veterans reported important stigmatization and barriers to receiving services exclusively from the VA, including mutable health delivery system factors.
