Comparing the unified protocol for transdiagnostic treatment of emotional disorders to prolonged exposure for the treatment of PTSD: Design of a non-inferiority randomized controlled trial

Background

Prolonged Exposure (PE), a trauma-focused therapy, is one of the most efficacious treatments available for PTSD. However, many people with PTSD do not lose their diagnosis following delivery of PE. The Unified Protocol (UP) for Transdiagnostic Treatment of Emotional Disorders is a non-trauma focused treatment that may offer an alternative treatment for PTSD.

Methods

This paper describes the study protocol for IMPACT, an assessor-blinded randomized controlled trial that examines the non-inferiority of UP relative to PE for participants who meet DSM-5 criteria for current PTSD. One hundred and twenty adult participants with PTSD will be randomized to receive either 10 × 90-min sessions of UP or PE with a trained provider. The primary outcome is severity of PTSD symptoms assessed by the Clinician Administered PTSD Scale for DSM-5 (CAPS-5) at post-treatment.

Discussion

While evidence-based treatments are available for PTSD, high levels of treatment dropout and non-response require new approaches to be tested. The UP is based on emotion regulation theory and is effective in treating anxiety and depressive disorders, however, there has been limited application to PTSD. This is the first rigorous study comparing UP to PE in a non-inferiority randomized controlled trial and may help improve clinical outcomes for those with PTSD.

Trial registration

This trial was prospectively registered with the Australian New Zealand Clinical Trials Registry, Trial ID (ACTRN12619000543189).

Involving families in Veteran mental health care: Key considerations and recommendations

LAY SUMMARY

When Veterans seek and receive mental health care, their family members are often involved, directly or indirectly, in the process. Within Canada, recognition of the need for family-centred policies and practices is growing; however, family involvement in care is generally the exception rather than the rule. A recently developed Conceptual Framework advocates for a transformed mental health system centred on the experiences, needs, and preferences of Veterans and their families. This system may be well suited to a shift toward family-involved care. Drawing on this framework, this article makes a case for specifically involving families in Veteran mental health care. In particular, the crucial relationship between family and Veteran well-being is considered, as well as key benefits of and potential barriers to involvement. With these considerations in mind, some recommendations are made to move research, practice, and policy forward. These include 1) formalizing the definition of family, 2) developing a more comprehensive and nuanced understanding of Veteran families and their involvement, and 3) using educational and guidance materials to improve knowledge and build capacity. Despite potential limitations, these considerations and recommendations offer an opportunity to advance dialogue related to meaningful and safe involvement of families in Veteran mental health care.

Virtually-delivered Sudarshan Kriya Yoga (SKY) for Canadian veterans with PTSD: A study protocol for a nation-wide effectiveness and implementation evaluation

BACKGROUND

Post-traumatic stress disorder (PTSD) remains a significant treatment challenge among Canadian veterans. Currently accessible pharmacological and non-pharmacological interventions for PTSD often do not lead to resolution of PTSD as a categorical diagnosis and have significant non-response rates. Sudarshan Kriya Yoga (SKY), a complementary and integrative health (CIH) intervention, can improve symptoms of PTSD. In response to the COVID-19 pandemic, this intervention has pivoted to virtual delivery and may be reaching new sets of participants who face multiple barriers to care.

OBJECTIVE

To evaluate the implementation and effectiveness of virtually delivered Sudarshan Kriya Yoga (SKY) on decreasing PTSD symptom severity, symptoms of depression, anxiety, and pain, and improving quality of life in Canadian veterans affected by PTSD.

METHODS AND ANALYSIS

Using a mixed-methods approach guided by the RE-AIM framework, we will conduct a hybrid type II effectiveness and implementation study of virtually delivered Sudarshan Kriya Yoga (SKY) for Canadian veterans. Effectiveness will be evaluated by comparing virtually delivered SKY to a waitlist control in a single-blinded (investigator and data analyst) randomized controlled trial (RCT). Change in PTSD symptoms (PCL-5) is the primary outcome and quality of life (SF-36), symptoms of depression (PHQ-9), anxiety (GAD-7), and pain (BPI) are secondary outcomes. The SKY intervention will be conducted over a 6-week period with assessments at baseline, 6-weeks, 12-weeks, and 30 weeks. The reach, effectiveness, adoption, implementation, and maintenance of the intervention will be evaluated through one-on-one semi-structured interviews with RCT participants, SKY instructors, health professionals, and administrators that work with veterans.

DISCUSSION

This is the first investigation of the virtual delivery of SKY for PTSD in veterans and aims to determine if the intervention is effective and implementable at scale.

Mental Health Reform: Design and Implementation of a System to Optimize Outcomes for Veterans and Their Families

The social, health, and economic burden of mental health problems in the veteran community is heavy. Internationally, the array of services and support available to veterans and their families are extensive but vary in quality, are often disconnected, complex to navigate, and lack clear coordination. This paper describes a conceptual framework to guide the design and implementation of a system of services and supports to optimize the mental health and wellbeing of all veterans and their families. The framework recognizes the diversity of veterans across intersecting identities that uniquely shape experiences of posttraumatic mental health and wellbeing. It brings together several strands of research: the values and principles that should underpin the system; the needs of diverse veterans and their families; challenges in the current services and supports; evidence-based interventions; and principles of effective implementation. Central to the future system design is a next generation stepped model of care that organizes best and next practice interventions in a coherent system, matches service provision to level of need and addresses access and navigation. Practical guidance on implementation provides an aspirational and flexible structure for system evolution, and a template for all stakeholders-individuals, groups, agencies and organizations-to effect system change.

Intimate Partner Violence (IPV) in Military and Veteran Populations: A Systematic Review of Population-Based Surveys and Population Screening Studies

Intimate partner violence (IPV) may be a major concern in military and veteran populations, and the aims of this systematic review were to (1) provide best available estimates of overall prevalence based on studies that are most representative of relevant populations, and (2) contextualise these via examination of IPV types, impacts, and context. An electronic search of PsycINFO, CINHAL, PubMed, and the Cochrane Library databases identified studies utilising population-based designs or population screening strategies to estimate prevalence of IPV perpetration or victimisation reported by active duty (AD) military personnel or veterans. Random effects meta-analyses were used for quantitative analyses and were supplemented by narrative syntheses of heterogeneous data. Thirty-one studies involving 172,790 participants were included in meta-analyses. These indicated around 13% of all AD personnel and veterans reported any recent IPV perpetration, and around 21% reported any recent victimisation. There were higher rates of IPV perpetration in studies of veterans and health service settings, but no discernible differences were found according to gender, era of service, or country of origin. Psychological IPV was the most common form identified, while there were few studies of IPV impacts, or coercive and controlling behaviours. The findings demonstrate that IPV perpetration and victimisation occur commonly among AD personnel and veterans and highlight a strong need for responses across military and veteran-specific settings. However, there are gaps in understanding of impacts and context for IPV, including coercive and controlling behaviours, which are priority considerations for future research and policy.

Health Service Interventions for Intimate Partner Violence among Military Personnel and Veterans: A Framework and Scoping Review

IPV is a significant concern among active duty (AD) military personnel or veterans, and there is a need for initiatives to address violence perpetrated by such personnel, and IPV victimisation in military and veteran-specific contexts. The aim of this paper was to provide an overview of major IPV intervention approaches and evidence in military and veteran-specific health services. A scoping review was conducted involving a systematic search of all available published studies describing IPV interventions in military and veteran-specific health services. Findings were synthesised narratively, and in relation to a conceptual framework that distinguishes across prevention, response, and recovery-oriented strategies. The search identified 19 studies, all from the U.S., and only three comprised randomised trials. Initiatives addressed both IPV perpetration and victimisation, with varied interventions targeting the latter, including training programs, case identification and risk assessment strategies, and psychosocial interventions. Most initiatives were classified as responses to IPV, with one example of indicated prevention. The findings highlight an important role for specific health services in addressing IPV among AD personnel and veterans, and signal intervention components that should be considered. The limited amount of empirical evidence indicates that benefits of interventions remain unclear, and highlights the need for targeted research.

An Assessment Framework for e-Mental Health Apps in Canada: Results of a Modified Delphi Process

Background

The number of e-mental health apps is increasing rapidly. Studies have shown that the use of some apps is beneficial, whereas others are ineffective or do not meet users’ privacy expectations. Individuals and organizations that curate, recommend, host, use, or pay for apps have an interest in categorizing apps according to the consensus criteria of usability and effectiveness. Others have previously published recommendations for assessing health-related apps; however, the extent to which these recommendations can be generalized across different population groups (eg, culture, gender, and language) remains unclear. This study describes an attempt by Canadian stakeholders to develop an e-mental health assessment framework that responds to the unique needs of people living in Canada in an evidence-based manner.

Objective

The objective of our study was to achieve consensus from a broad group of Canadian stakeholders on guiding principles and criteria for a framework to assess e-mental health apps in Canada.

Methods

We developed an initial set of guiding principles and criteria from a rapid review and environmental scan of pre-existing app assessment frameworks. The initial list was refined through a two-round modified Delphi process. Participants (N=25) included app developers and users, health care providers, mental health advocates, people with lived experience of a mental health problem or mental illness, policy makers, and researchers. Consensus on each guideline or criterion was defined a priori as at least 70% agreement. The first round of voting was conducted electronically. Prior to Round 2 voting, in-person presentations from experts and a persona empathy mapping process were used to explore the perspectives of diverse stakeholders.

Results

Of all respondents, 68% (17/25) in Round 1 and 100% (13/13) in Round 2 agreed that a framework for evaluating health apps is needed to help Canadian consumers identify high-quality apps. Consensus was reached on 9 guiding principles: evidence based, gender responsive, culturally appropriate, user centered, risk based, internationally aligned, enabling innovation, transparent and fair, and based on ethical norms. In addition, 15 informative and evaluative criteria were defined to assess the effectiveness, functionality, clinical applicability, interoperability, usability, transparency regarding security and privacy, security or privacy standards, supported platforms, targeted users, developers’ transparency, funding transparency, price, user desirability, user inclusion, and meaningful inclusion of a diverse range of communities.

Conclusions

Canadian mental health stakeholders reached the consensus on a framework of 9 guiding principles and 15 criteria important in assessing e-mental health apps. What differentiates the Canadian framework from other scales is explicit attention to user inclusion at all stages of the development, gender responsiveness, and cultural appropriateness. Furthermore, an empathy mapping process markedly influenced the development of the framework. This framework may be used to inform future mental health policies and programs.

Low risk of significant echocardiographic valvulopathy in patients treated with anorectic drugs

BACKGROUND

Phentermine--fenfluramine and dexfenfluramine use for weight loss has been previously associated with increased prevalence of valvular heart disease. This association was initially based on small numbers of patients, limited data on dose and duration of drug therapy, and no correlation with matched controls.

METHODS

Our investigation involved 343 obese subjects enrolled in a prospective, strict weight loss, research protocol from September 1994 to September 1997. All subjects underwent transthoracic echocardiography for significant valvular lesions within a mean of 121 days from the manufacturer's announcement of the voluntary withdrawal of fenfluramine and dexfenfluramine from the market. All echocardiograms were interpreted by 2 independent readers.

RESULTS

The study population included 281 females and 62 males with a mean age of 46.7+/-9.1 years and mean initial body mass index of 40.1+/-8.1 kg/m(2). Using the Food and Drug Administration's criteria, only 21 subjects (6.1%) had significant valvular lesions. Aortic regurgitation was detected in 18 subjects, mitral regurgitation in 3 subjects, and both aortic and mitral regurgitation in 1 subject; no one had severe regurgitation. Significant valvular disease did not correlate with age, gender, initial/ending body mass index, the drug dose, duration of drug therapy, or serotonin reuptake inhibitors.

CONCLUSIONS

Anorexigen therapy is associated with a low prevalence of significant valvular regurgitation. Late valvular abnormalities from drug treatment await long term prospective studies.

MRI and echocardiography: how do they compare in adults?

TTE with color flow imaging remains the most appropriate initial method for imaging CHD in adults. In many patients with minor abnormalities, this will be the only imaging required. For complicated intracardiac anomalies not well shown by TTE, TEE or MRI are usually adequate with the choice of technique being dependent on the availability of appropriate equipment and expertise. For great vessel abnormalities, further evaluation with MRI and MRA is most appropriate. In patients suspected of having significant systemic or pulmonary venous abnormalities or abnormalities of the aortic arch, MRI and MRA should be regarded as the definitive imaging technique. MRI and MRA are robust methods for evaluating intracardiac disease and can provide accurate information on cardiac chamber anatomy relationships, valvar lesions, and shunts. However, in most patients, this information is provided more rapidly and cost effectively by color Doppler echocardiography.
