Interventions for adults with a history of complex traumatic events: the INCiTE mixed-methods systematic review

Interventions targeting emotion regulation: A systematic umbrella review

BACKGROUND

Emotion dysregulation (ED), the difficulty in modulating which emotions are felt, and when and how they are expressed or experienced, has been implicated in an array of psychological disorders. Despite potentially different manifestations depending on the disorder, this symptom is emerging as a transdiagnostic construct that can and should be targeted early, given the associations with various maladaptive behaviors as early as childhood and adolescence. As such, our goal was to investigate the psychotherapeutic interventions used to address ED and gauge their effectiveness, safety, and potential mechanisms across various populations.

METHODS

This umbrella systematic review, pre-registered under PROSPERO (registration: CRD42023411452), consolidates evidence from systematic reviews and meta-analyses on psychotherapeutic interventions targeting ED, in accordance with PRISMA guidelines.

RESULTS

Our synthesis of quantitative and qualitative evidence from 21 systematic reviews (including 11 meta-analyses) points-with moderate overall risk of bias-to the effectiveness of Dialectical Behavior Therapy and Cognitive Behavioral Therapy in reducing ED in a wide range of adult transdiagnostic psychiatric patients and healthy participants. Similar results have emerged in other less extensively researched methods as well. However, results on adolescents and children are sparse, highlighting the need for additional research to tailor these interventions to the unique challenges of ED in younger populations with diverse externalizing and internalizing disorders.

CONCLUSIONS

These demonstrated transdiagnostic advantages of psychotherapy for ED underscore the potential for specifically designed interventions that address this issue directly, particularly for high-risk individuals. In these individuals, early interventions targeting transdiagnostic core dimensions may mitigate the emergence of full-blown disorders. Future research on the mediating factors, the durability of intervention effects, and the exploration of understudied interventions and populations may enhance prevention and treatment efficiency, enhancing the quality of life for those affected by varied manifestations of ED.

Childhood neglect, the neglected trauma. A systematic review and meta-analysis of its prevalence in psychiatric disorders

Traumatic events increase risk of mental illnesses, but childhood neglect prevalence in psychiatric disorders is understudied. This systematic review and meta-analysis assessed neglect prevalence, including emotional neglect (EN) and physical neglect (PN), among adults with psychiatric disorders. We conducted a systematic search and meta-analysis in 122 studies assessing different psychiatric disorders. Prevalence was 46.6% (95%CI[34.5-59.0]) for unspecified neglect (Ne), 43.1% (95%CI[39.0-47.4]) for EN, and 34.8% (95%CI[30.6-39.2]) for PN. Although a moderating effect of the psychiatric diagnostic category was not confirmed, some clinical diagnoses had significantly lower prevalence rates than others. Patients with bipolar disorder and major depressive disorder showed lower prevalence rates of EN and PN, whereas lower prevalence was found in psychotic disorders and eating disorders for PN only. Neglect assessment was a significant moderator for Ne and PN. No moderating effect of age and sex on neglect prevalence was found. Heterogeneity levels within and between psychiatric diagnostic categories remained high. This is the first meta-analysis examining diverse types of neglect prevalence considering different psychiatric diagnoses. Our results explore the prevalence of childhood neglect and its subtypes among adults with psychiatric disorders, contributing to understanding the nuanced interplay between neglect and specific psychiatric conditions, and guiding interventions for affected individuals.

The development and evaluation of a virtual, asynchronous, trauma-focused treatment program for adult survivors of childhood interpersonal trauma

BACKGROUND

The long-term mental and physical health implications of childhood interpersonal trauma on adult survivors is immense, however, there is a lack of available trauma-focused treatment services that are widely accessible. This study, utilizing a user-centered design process, sought feedback on the initial design and development of a novel, self-paced psychoeducation and skills-based treatment intervention for this population.

AIMS

To explore the views and perspectives of adult survivors of childhood interpersonal trauma on the first two modules of an asynchronous trauma-focused treatment program.

METHODS

Fourteen participants from our outpatient hospital service who completed the modules consented to provide feedback on their user experience. A thematic analysis of the three focus groups was conducted.

RESULTS

Four major themes emerged from the focus groups: (1) technology utilization, (2) module content, (3) asynchronous delivery, and (4) opportunity for interactivity. Participants noted the convenience of the platform and the use of multimedia content to increase engagement and did not find the modules to be emotionally overwhelming.

CONCLUSIONS

Our research findings suggest that an asynchronous virtual intervention for childhood interpersonal trauma survivors may be a safe and acceptable way to provide a stabilization-focused intervention on a wider scale.

Outcomes of trauma-informed care on the psychological health of women experiencing intimate partner violence: A systematic review and meta-analysis

WHAT IS KNOWN ON THE SUBJECT?: Women are more likely to experience intimate partner violence (IPV) than men; 19.2%-69.0% of women have experienced IPV, and the percentage is increasing. Survivors of IPV suffer from physical, psychological, social and reproductive health problems and numerous adverse health consequences such as post-traumatic stress disorder, depression and anxiety. These are considered IPV comorbidities, especially among women. WHAT THE PAPER ADDS TO EXISTING KNOWLEDGE?: This study reviews and reinforces existing scientific knowledge regarding the application of trauma-informed care (TIC), including intervention content or type, frequency, duration of session and length. This study focused on the effects of TIC. Furthermore, it examines short-term (3 months) and medium-term (6 months) outcome effects, which are more significant for clinical practice. WHAT ARE THE IMPLICATIONS FOR PRACTICE?: Development of a standardized protocol to address specific needs for TIC in IPV care settings. Among multidisciplinary teams, nurses are the ideal professionals to support women experiencing IPV. They can understand their traumatic experiences better, improve their therapeutic relationships and engage patients in collaborative care.

ABSTRACT

INTRODUCTION: Post-traumatic stress disorder (PTSD), depression and anxiety are considered intimate partner violence (IPV) comorbidities, especially among women. Trauma-informed care (TIC) is the most common element of IPV care.

AIM

This study analysed the short-term (3 months) and medium-term (6 months) outcomes of TIC on PTSD, depression and anxiety in women experiencing IPV.

METHOD

The Preferred Items for Systematic Reviews and Meta-Analysis guidelines were followed, and databases were searched from their inception to September 2022.

RESULTS

Thirteen randomized controlled trials included 850 women randomly assigned to the TIC and usual care groups. Overall, TIC showed a superior psychological health-improving effect. Depression and anxiety significantly improved after treatment and at three and 6 months. No difference was observed in PTSD between the two groups at 3 and 6 months.

DISCUSSION

The growing evidence demonstrates that the lack of IPV intervention effects reported by reviews may be due to the attributes of PTSD, heterogeneity of TIC intervention design and components of TIC. Therefore, its clinical efficacy remains inconclusive.

IMPLICATIONS FOR PRACTICE

We analysed studies by stratifying intervention frequencies of once or twice a week. Regardless of the intervention frequency, length and design, PTSD decreased immediately after the TIC intervention. However, a significant difference in depression was observed after a TIC intervention of above 9 weeks.

The Management of Posttraumatic Stress Disorder and Acute Stress Disorder: Synopsis of the 2023 U.S. Department of Veterans Affairs and U.S. Department of Defense Clinical Practice Guideline

DESCRIPTION

The U.S. Department of Veterans Affairs (VA) and Department of Defense (DoD) worked together to revise the 2017 VA/DoD Clinical Practice Guideline for the Management of Posttraumatic Stress Disorder and Acute Stress Disorder. This article summarizes the 2023 clinical practice guideline (CPG) and its development process, focusing on assessments and treatments for which evidence was sufficient to support a recommendation for or against.

METHODS

Subject experts from both departments developed 12 key questions and reviewed the published literature after a systematic search using the PICOTS (population, intervention, comparator, outcomes, timing of outcomes measurement, and setting) method. The evidence was then evaluated using the GRADE (Grading of Recommendations Assessment, Development and Evaluation) method. Recommendations were made after consensus was reached; they were based on quality and strength of evidence and informed by other factors, including feasibility and patient perspectives. Once the draft was peer reviewed by an external group of experts and their inputs were incorporated, the final document was completed.

RECOMMENDATIONS

The revised CPG includes 34 recommendations in the following 5 topic areas: assessment and diagnosis, prevention, treatment, treatment of nightmares, and treatment of posttraumatic stress disorder (PTSD) with co-occurring conditions. Six recommendations on PTSD treatment were rated as strong. The CPG recommends use of specific manualized psychotherapies over pharmacotherapy; prolonged exposure, cognitive processing therapy, or eye movement desensitization and reprocessing psychotherapy; paroxetine, sertraline, or venlafaxine; and secure video teleconferencing to deliver recommended psychotherapy when that therapy has been validated for use with video teleconferencing or when other options are unavailable. The CPG also recommends against use of benzodiazepines, cannabis, or cannabis-derived products. Providers are encouraged to use this guideline to support evidence-based, patient-centered care and shared decision making to optimize individuals' health outcomes and quality of life.

Association of medication clusters and subsequent labor market marginalization in refugee and Swedish-born young adults with common mental disorders in Sweden

Little is known about the association between common mental disorders (CMD) and labor market integration among refugee and Swedish-born young adults. Socially disadvantaged patients such as refugees are more likely to discontinue their medication use prematurely. This study aimed to identify clusters of individuals with similar psychotropic medication patterns; and examine the relationship between cluster membership with labor market marginalization (LMM) in refugee and Swedish-born young adults with CMD. The study uses a longitudinal matched cohort aged 18-24 years with CMD diagnoses from Swedish registers covering 2006-2016. Dispensed psychotropic medications (antidepressants, antipsychotics, anxiolytics, sedative-hypnotics, mood stabilizers) were collected one year before and after CMD diagnosis. Clusters of patients with similar time courses of prescribed dosages were algorithmically identified. The association of cluster membership with subsequent LMM, (long-term sickness absence, SA, disability pension, DP, or long-term unemployment, UE) was assessed using Cox regression. Among 12,472 young adults with CMD, there were 13.9% with SA, 11.9% with DP, and 13.0% with UE during a mean follow-up of 4.1 years (SD 2.3 years). Six clusters of individuals were identified. A cluster with a sustained increase in all medication types yielded the highest hazard ratio (HR [95% CI]) 1.69 [1.34, 2.13] for SA and 2.63 [2.05, 3.38] for DP. The highest HRs of UE give a cluster with a concentrated peak in antidepressants at CMD diagnosis (HR 1.61[1.18, 2.18]). Refugees and Swedish-born showed similar associations between clusters and LMM. To prevent LMM, targeted support and early assessment of CMD treatment are needed for individuals with a sustained increase in psychotropic medication after CMD diagnosis and for refugees in high-risk clusters for UE characterized by a rapid lowering of treatment dosages, which could be an indicator for premature medication discontinuation.

Effectiveness and User Experience of Virtual Reality for Social Anxiety Disorder: Systematic Review

BACKGROUND

Social anxiety disorder (SAD) is a debilitating psychiatric disorder that affects occupational and social functioning. Virtual reality (VR) therapies can provide effective treatment for people with SAD. However, with rapid innovations in immersive VR technology, more contemporary research is required to examine the effectiveness and concomitant user experience outcomes (ie, safety, usability, acceptability, and attrition) of emerging VR interventions for SAD.

OBJECTIVE

The aim of this systematic review was to examine the effectiveness and user experience of contemporary VR interventions among people with SAD.

METHODS

The Cochrane Library, Emcare, PsycINFO, PubMed, ScienceDirect, Scopus, and Web of Science databases were searched between January 1, 2012, and April 26, 2022. Deduplicated search results were screened based on title and abstract information. Full-text examination was conducted on 71 articles. Studies of all designs and comparator groups were included if they appraised the effectiveness and user experience outcomes of any immersive VR intervention among people with SAD. A standardized coding sheet was used to extract data on key participant, intervention, comparator, outcome, and study design items.

RESULTS

The findings were tabulated and discussed using a narrative synthesis. A total of 18 studies met the inclusion criteria.

CONCLUSIONS

The findings showed that VR exposure therapy-based interventions can generally provide effective, safe, usable, and acceptable treatments for adults with SAD. The average attrition rate from VR treatment was low (11.36%) despite some reported user experience difficulties, including potential simulator sickness, exposure-based emotional distress, and problems with managing treatment delivered in a synchronous group setting. This review also revealed several research gaps, including a lack of VR treatment studies on children and adolescents with SAD as well as a paucity of standardized assessments of VR user experience interactions. More studies are required to address these issues.

Fair Healthcare Practices in Orthopedics Assessed with a New Framework

Background and Objectives: Healthcare systems are supported by the European ideology to develop their egalitarian concerns and to encourage the correct and fair behavior of medical staff. By integrating fair healthcare practices into sustainability, this requirement is addressed. In this research, our objective is to develop and validate, in the current activity of healthcare facilities, a new instrument for evaluating fair healthcare practices as a component of social responsibility integrated into sustainability. Materials and Methods: The research methods consist of deciding the domains of a new framework that integrates fair healthcare practices; the collection of the most recent fair healthcare practices reported by healthcare facilities around the world; elaboration of the contents and evaluation grids of the indicators; the integration of indicators related to fair healthcare practices in the matrix of the new framework for sustainable development; validation of the theoretical model at an orthopedic hospital. Results: The theoretical model of the new framework is composed of five domains: organizational management, provision of sustainable medical care services, economic, environmental, and social. The last domain is developed on the structure of the seven subdomains of the social responsibility standard ISO 26000. The seven indicators that describe fair healthcare practices are attitudes of the profession towards accreditation, effective intervention application, promoting a culture of patient safety, characteristics that affect the effectiveness of transfers, effective healthcare practices, feedback to medical staff, safety checklists. The new reference framework was implemented and validated in practice at an emergency hospital with an orthopedic profile. Conclusions: The practical implementation highlighted the usefulness of the new reference framework, its compatibility, and the possibility of integration with the reference frameworks for the evaluation of European hospitals, with the national legislation for the accreditation of hospitals and outpatient units, as well as with the ISO 9001 standard regarding the implementation of quality management systems. Its added value consists in promoting sustainable development by orienting staff, patients, and interested parties towards sustainability.

Data visualisation approaches for component network meta-analysis: visualising the data structure

BACKGROUND

Health and social care interventions are often complex and can be decomposed into multiple components. Multicomponent interventions are often evaluated in randomised controlled trials. Across trials, interventions often have components in common which are given alongside other components which differ across trials. Multicomponent interventions can be synthesised using component NMA (CNMA). CNMA is limited by the structure of the available evidence, but it is not always straightforward to visualise such complex evidence networks. The aim of this paper is to develop tools to visualise the structure of complex evidence networks to support CNMA.

METHODS

We performed a citation review of two key CNMA methods papers to identify existing published CNMA analyses and reviewed how they graphically represent intervention complexity and comparisons across trials. Building on identified shortcomings of existing visualisation approaches, we propose three approaches to standardise visualising the data structure and/or availability of data: CNMA-UpSet plot, CNMA heat map, CNMA-circle plot. We use a motivating example to illustrate these plots.

RESULTS

We identified 34 articles reporting CNMAs. A network diagram was the most common plot type used to visualise the data structure for CNMA (26/34 papers), but was unable to express the complex data structures and large number of components and potential combinations of components associated with CNMA. Therefore, we focused visualisation development around representing the data structure of a CNMA more completely. The CNMA-UpSet plot presents arm-level data and is suitable for networks with large numbers of components or combinations of components. Heat maps can be utilised to inform decisions about which pairwise interactions to consider for inclusion in a CNMA model. The CNMA-circle plot visualises the combinations of components which differ between trial arms and offers flexibility in presenting additional information such as the number of patients experiencing the outcome of interest in each arm.

CONCLUSIONS

As CNMA becomes more widely used for the evaluation of multicomponent interventions, the novel CNMA-specific visualisations presented in this paper, which improve on the limitations of existing visualisations, will be important to aid understanding of the complex data structure and facilitate interpretation of the CNMA results.

Prevalence of Childhood Trauma in a Community-Based Mental Health Clinic

A large number of individuals in the US have experienced childhood trauma. However, little is known about the prevalence of trauma in a diverse patient population entering treatment in a community mental health center. To assess early trauma in this population, the Adverse Childhood Experience (ACEs) questionnaire was administered to 856 participants over a nine-month period. 40% reported four or more ACEs. Among high scorers, emotional abuse, physical abuse and emotional neglect were the most prevalent ACE experiences. High mean ACE sum scores were observed among patients with PTSD, depression, impulse disorder and substance use disorder. Having a higher ACE sum score was associated with a greater number of co-occurring psychiatric disorders. Characterizing ACEs by patient sociodemographic attributes and psychiatric diagnoses extracted from the electronic medical records (EMR) can benefit therapeutic interventions. These findings indicate a need for creating more trauma-informed settings with knowledgeable, trained staff.

Interventions from pregnancy to two years after birth for parents experiencing complex post-traumatic stress disorder and/or with childhood experience of maltreatment

BACKGROUND

Acceptable, effective and feasible support strategies (interventions) for parents experiencing complex post-traumatic stress disorder (CPTSD) symptoms or with a history of childhood maltreatment may offer an opportunity to support parental recovery, reduce the risk of intergenerational transmission of trauma and improve life-course trajectories for children and future generations. However, evidence relating to the effect of interventions has not been synthesised to provide a comprehensive review of available support strategies. This evidence synthesis is critical to inform further research, practice and policy approaches in this emerging area.

OBJECTIVES

To assess the effects of interventions provided to support parents who were experiencing CPTSD symptoms or who had experienced childhood maltreatment (or both), on parenting capacity and parental psychological or socio-emotional wellbeing.

SEARCH METHODS

In October 2021 we searched CENTRAL, MEDLINE, Embase, six other databases and two trials registers, together with checking references and contacting experts to identify additional studies.

SELECTION CRITERIA

All variants of randomised controlled trials (RCTs) comparing any intervention delivered in the perinatal period designed to support parents experiencing CPTSD symptoms or with a history of childhood maltreatment (or both), to any active or inactive control. Primary outcomes were parental psychological or socio-emotional wellbeing and parenting capacity between pregnancy and up to two years postpartum.

DATA COLLECTION AND ANALYSIS

Two review authors independently assessed the eligibility of trials for inclusion, extracted data using a pre-designed data extraction form, and assessed risk of bias and certainty of evidence. We contacted study authors for additional information as required. We analysed continuous data using mean difference (MD) for outcomes using a single measure, and standardised mean difference (SMD) for outcomes using multiple measures, and risk ratios (RR) for dichotomous data. All data are presented with 95% confidence intervals (CIs). We undertook meta-analyses using random-effects models.

MAIN RESULTS

We included evidence from 1925 participants in 15 RCTs that investigated the effect of 17 interventions. All included studies were published after 2005. Interventions included seven parenting interventions, eight psychological interventions and two service system approaches. The studies were funded by major research councils, government departments and philanthropic/charitable organisations. All evidence was of low or very low certainty. Parenting interventions Evidence was very uncertain from a study (33 participants) assessing the effects of a parenting intervention compared to attention control on trauma-related symptoms, and psychological wellbeing symptoms (postpartum depression), in mothers who had experienced childhood maltreatment and were experiencing current parenting risk factors. Evidence suggested that parenting interventions may improve parent-child relationships slightly compared to usual service provision (SMD 0.45, 95% CI -0.06 to 0.96; I2 = 60%; 2 studies, 153 participants; low-certainty evidence). There may be little or no difference between parenting interventions and usual perinatal service in parenting skills including nurturance, supportive presence and reciprocity (SMD 0.25, 95% CI -0.07 to 0.58; I2 = 0%; 4 studies, 149 participants; low-certainty evidence). No studies assessed the effects of parenting interventions on parents' substance use, relationship quality or self-harm. Psychological interventions Psychological interventions may result in little or no difference in trauma-related symptoms compared to usual care (SMD -0.05, 95% CI -0.40 to 0.31; I2 = 39%; 4 studies, 247 participants; low-certainty evidence). Psychological interventions may make little or no difference compared to usual care to depression symptom severity (8 studies, 507 participants, low-certainty evidence, SMD -0.34, 95% CI -0.66 to -0.03; I2 = 63%). An interpersonally focused cognitive behavioural analysis system of psychotherapy may slightly increase the number of pregnant women who quit smoking compared to usual smoking cessation therapy and prenatal care (189 participants, low-certainty evidence). A psychological intervention may slightly improve parents' relationship quality compared to usual care (1 study, 67 participants, low-certainty evidence). Benefits for parent-child relationships were very uncertain (26 participants, very low-certainty evidence), while there may be a slight improvement in parenting skills compared to usual care (66 participants, low-certainty evidence). No studies assessed the effects of psychological interventions on parents' self-harm. Service system approaches One service system approach assessed the effect of a financial empowerment education programme, with and without trauma-informed peer support, compared to usual care for parents with low incomes. The interventions increased depression slightly (52 participants, low-certainty evidence). No studies assessed the effects of service system interventions on parents' trauma-related symptoms, substance use, relationship quality, self-harm, parent-child relationships or parenting skills.

AUTHORS' CONCLUSIONS

There is currently a lack of high-quality evidence regarding the effectiveness of interventions to improve parenting capacity or parental psychological or socio-emotional wellbeing in parents experiencing CPTSD symptoms or who have experienced childhood maltreatment (or both). This lack of methodological rigour and high risk of bias made it difficult to interpret the findings of this review. Overall, results suggest that parenting interventions may slightly improve parent-child relationships but have a small, unimportant effect on parenting skills. Psychological interventions may help some women stop smoking in pregnancy, and may have small benefits on parents' relationships and parenting skills. A financial empowerment programme may slightly worsen depression symptoms. While potential beneficial effects were small, the importance of a positive effect in a small number of parents must be considered when making treatment and care decisions. There is a need for further high-quality research into effective strategies for this population.

Complex post-traumatic stress disorder

Complex post-traumatic stress disorder (complex PTSD) is a severe mental disorder that emerges in response to traumatic life events. Complex PTSD is characterised by three core post-traumatic symptom clusters, along with chronic and pervasive disturbances in emotion regulation, identity, and relationships. Complex PTSD has been adopted as a new diagnosis in the ICD-11. Individuals with complex PTSD typically have sustained or multiple exposures to trauma, such as childhood abuse and domestic or community violence. The disorder has a 1-8% population prevalence and up to 50% prevalence in mental health facilities. Progress in diagnostics, assessment, and differentiation from post-traumatic stress disorder and borderline personality disorder is reported, along with assessment and treatment of children and adolescents. Studies recommend multicomponent therapies starting with a focus on safety, psychoeducation, and patient-provider collaboration, and treatment components that include self-regulatory strategies and trauma-focused interventions.

Skills Training in Affective and Interpersonal Regulation Narrative Therapy for women with ICD-11 complex PTSD related to childhood abuse in Japan: a pilot study

BACKGROUND

Skills Training in Affective and Interpersonal Regulation (STAIR) Narrative Therapy (SNT) has shown efficacy in alleviating symptoms of posttraumatic stress disorder (PTSD) and improving emotion regulation and interpersonal skills among individuals with complex trauma, such as childhood abuse. Although this therapy is expected to be effective for patients with complex PTSD (CPTSD), no study has directly assessed diagnostic and symptom outcomes. Moreover, the potential of therapy to achieve good outcomes in non-Western countries remains unclear.

OBJECTIVE

This pilot study examined the feasibility, safety, and outcomes of SNT for CPTSD among women with a history of childhood abuse in a Japanese clinical setting.

METHODS

Ten women aged 21-54 years (M = 29.1 years) with childhood-abuse-related ICD-11 CPTSD were enrolled in this study. The International Trauma Interview and International Trauma Questionnaire were administered to diagnose CPTSD and assess its severity. Symptoms of dissociation and depression, difficulties in emotion regulation and interpersonal relationships, quality of life, and negative cognitions were assessed pretreatment, midtreatment (after the STAIR phase), and immediately posttreatment (after the Narrative Therapy phase), in addition to 3 months after treatment.

RESULTS

Seven of the 10 participants completed the treatment. The therapists' adherence to the therapy protocol was 96.4%, ranging from 93.6% to 100% across therapists. Serious adverse events were not observed. Among the seven completers, six at posttreatment and all at follow-up no longer met CPTSD diagnosis. Exploratory analyses using the linear mixed-effects model showed significant improvements at posttreatment and follow-up for almost all the variables.

CONCLUSIONS

The results provide preliminary evidence for the feasibility and safety of SNT for CPTSD in a Japanese clinical setting. This study is the first to report the use of SNT for individuals diagnosed with ICD-11 CPTSD using reliable clinician and self-report measures.

HIGHLIGHTS

This study examined the feasibility and safety of STAIR Narrative Therapy for women with ICD-11 CPTSD related to childhood abuse in a Japanese clinical setting.High therapy adherence was observed.No serious adverse events occurred.

Methods to Generate Innovative Research Ideas and Improve Patient and Public Involvement in Modern Epidemiological Research: Review, Patient Viewpoint, and Guidelines for Implementation of a Digital Cohort Study

Background

Patient and public involvement (PPI) in research aims to increase the quality and relevance of research by incorporating the perspective of those ultimately affected by the research. Despite these potential benefits, PPI is rarely included in epidemiology protocols.

Objective

The aim of this study is to provide an overview of methods used for PPI and offer practical recommendations for its efficient implementation in epidemiological research.

Methods

We conducted a review on PPI methods. We mirrored it with a patient advocate’s viewpoint about PPI. We then identified key steps to optimize PPI in epidemiological research based on our review and the viewpoint of the patient advocate, taking into account the identification of barriers to, and facilitators of, PPI. From these, we provided practical recommendations to launch a patient-centered cohort study. We used the implementation of a new digital cohort study as an exemplary use case.

Results

We analyzed data from 97 studies, of which 58 (60%) were performed in the United Kingdom. The most common methods were workshops (47/97, 48%); surveys (33/97, 34%); meetings, events, or conferences (28/97, 29%); focus groups (25/97, 26%); interviews (23/97, 24%); consensus techniques (8/97, 8%); James Lind Alliance consensus technique (7/97, 7%); social media analysis (6/97, 6%); and experience-based co-design (3/97, 3%). The viewpoint of a patient advocate showed a strong interest in participating in research. The most usual PPI modalities were research ideas (60/97, 62%), co-design (42/97, 43%), defining priorities (31/97, 32%), and participation in data analysis (25/97, 26%). We identified 9 general recommendations and 32 key PPI-related steps that can serve as guidelines to increase the relevance of epidemiological studies.

Conclusions

PPI is a project within a project that contributes to improving knowledge and increasing the relevance of research. PPI methods are mainly used for idea generation. On the basis of our review and case study, we recommend that PPI be included at an early stage and throughout the research cycle and that methods be combined for generation of new ideas. For e-cohorts, the use of digital tools is essential to scale up PPI. We encourage investigators to rely on our practical recommendations to extend PPI in future epidemiological studies.

Cost-effectiveness of mechanical thrombectomy for acute ischemic stroke in Brazil: Results from the RESILIENT trial

BACKGROUND

The RESILIENT trial demonstrated the clinical benefit of mechanical thrombectomy in patients presenting acute ischemic stroke secondary to anterior circulation large vessel occlusion in Brazil.

AIMS

This economic evaluation aims to assess the cost-utility of mechanical thrombectomy in the RESILIENT trial from a public healthcare perspective.

METHODS

A cost-utility analysis was applied to compare mechanical thrombectomy plus standard medical care (n = 78) vs. standard medical care alone (n = 73), from a subset sample of the RESILIENT trial (151 of 221 patients). Real-world direct costs were considered, and utilities were imputed according to the Utility-Weighted modified Rankin Score. A Markov model was structured, and probabilistic and deterministic sensitivity analyses were performed to evaluate the robustness of results.

RESULTS

The incremental costs and quality-adjusted life years gained with mechanical thrombectomy plus standard medical care were estimated at Int$ 7440 and 1.04, respectively, compared to standard medical care alone, yielding an incremental cost-effectiveness ratio of Int$ 7153 per quality-adjusted life year. The deterministic sensitivity analysis demonstrated that mRS-6 costs of the first year most affected the incremental cost-effectiveness ratio. After 1000 simulations, most of results were below the cost-effective threshold.

CONCLUSIONS

The intervention's clear long-term benefits offset the initially higher costs of mechanical thrombectomy in the Brazilian public healthcare system. Such therapy is likely to be cost-effective and these results were crucial to incorporate mechanical thrombectomy in the Brazilian public stroke centers.
