Real-Time Telehealth Versus Face-to-Face Management for Patients With PTSD in Primary Care: A Systematic Review and Meta-Analysis

Neurobiology and Treatment of Posttraumatic Stress Disorder

The recent worldwide surge of warfare and hostilities exposes increasingly large numbers of individuals to traumatic events, placing them at risk of developing posttraumatic stress disorder (PTSD) and challenging both clinicians and service delivery systems. This overview summarizes and updates the core knowledge of the genetic, molecular, and neural circuit features of the neurobiology of PTSD and advances in evidence-based psychotherapy, pharmacotherapy, neuromodulation, and digital treatments. While the complexity of the neurobiology and the biological and clinical heterogeneity of PTSD have challenged clinicians and researchers, there is an emerging consensus concerning the underlying mechanisms and approaches to diagnosis, treatment, and prevention of PTSD. This update addresses PTSD diagnosis, prevalence, course, risk factors, neurobiological mechanisms, current standard of care, and innovations in next-generation treatment and prevention strategies. It provides a comprehensive summary and concludes with areas of research for integrating advances in the neurobiology of the disorder with novel treatment and prevention targets.

State of the Science: Evidence-based treatments for posttraumatic stress disorder delivered via telehealth

Psychotherapy delivered via telehealth technology is not an artifact of the COVID-19 pandemic. Indeed, widespread, telehealth-delivered, evidence-based psychotherapy preceded the pandemic, as did randomized controlled noninferiority trials supporting this modality. It is, thus, not difficult to predict that telehealth will be an integral part of daily clinical life moving forward. With respect to posttraumatic stress disorder (PTSD) specifically, there is a substantial number of studies on the feasibility, acceptability, and effectiveness of evidence-based treatments provided via videoconferencing. In this review, we delineate the literature establishing strong support for remote delivery of prolonged exposure (PE) and cognitive processing therapy (CPT); there is also promising support for written exposure therapy (WET) and trauma-focused cognitive behavioral therapy (TF-CBT). We also mention adjunctive and integrative modifications to better serve patients with PTSD. One such intervention, behavioral activation and therapeutic exposure (BATE), has several studies supporting telehealth delivery, whereas concurrent treatment of PTSD and substance use disorders using the PE protocol (COPE) and cognitive behavioral therapy for insomnia (CBT-I) would benefit from further research. Integrating instrumental peer support into telehealth-delivered PE shows promise in retaining patients in treatment. Finally, we provide ideas to maximize telehealth delivery effectiveness, explore future research directions, and discuss ways to advocate for the expansion of telehealth services from an equity perspective.

The impact of telehealth care on escalation to emergency care: A systematic review and meta-analysis

OBJECTIVE

We compared the impact of accessing healthcare (1) by telehealth (via telephone or video) vs face-to-face; and (2) by telephone vs video telehealth care, on escalation to emergency care.

METHODS

We searched Medline, Embase and Cochrane CENTRAL to 24 July 2023; and conducted a citation analysis on 19 September 2023. We included randomised controlled trials. Risk of bias was assessed using Cochrane Tool 2. We calculated risk ratios for dichotomous outcomes and standardised mean difference for continuous outcomes.

RESULTS

Ten trials compared telehealth (five telephone, four video, one both) to face-to-face care. Six were overall low, three some concerns and one high risk of bias. There were no differences between telehealth and face-to-face for visits to the emergency department (RR 1.07, 95% CI 0.89 to 1.29), hospitalisations up to 12 months (RR 0.89, 95% CI 0.56 to 1.41), deaths or other adverse events. Costs of care were similar, as were patient satisfaction scores.Six trials compared telephone to video telehealth: three were overall low, two some concerns, and one high risk of bias. There were no differences between telephone and video for visits to the emergency department (RR 0.67, 95% CI 0.41 to 1.12), hospitalisations (RR 1.04, 95% CI 0.73 to 1.48), deaths, other adverse events, costs, or patient satisfaction. Healthcare provider satisfaction was high.

CONCLUSIONS

Telehealth care - delivered by telephone or by video - may be an appropriate alternative to face-to-face provision of care, as it does not increase the likelihood of escalation of care to the emergency department for patients in primary care, hospital outpatients, post-discharge patients or residents in aged care.

Digital health-based exposure therapies for patients with posttraumatic stress disorder: A systematic review of randomized controlled trials

Although exposure therapies have established effects in treating posttraumatic stress disorder (PTSD), these therapies might be hindered by issues of cost, distance, time, and human resources, which are potentially alleviated by digital health. Despite the potential of digital health, there is currently no systematic review specifically evaluating digital health-based exposure therapies. We aimed to conduct a systematic literature review of randomized controlled trials (RCTs) examining the impact of digital health-based exposure therapies in treating patients with PTSD. A literature search was conducted from December 31, 2023, to February 22, 2024, using the PubMed, Web of Science, and PsycINFO databases. A total of 12 RCTs with 1,361 participants were included in the systematic review. These RCTs were conducted mainly in the United States and primarily enrolled military samples. Overall, the utility of digital health-based exposure therapies appeared plausible and comparable to that of in-person therapies. The dropout rate was counterintuitively high, potentially due to technological issues and the absence of personal connections. The findings suggest that digital health-based exposure therapies may potentially resolve the issues of cost, distance, time, and human resources in the treatment of patients with PTSD. Future RCTs should employ larger sample sizes. Addressing technological challenges and the absence of personal connection may be important in resolving the high dropout rate.

Impact of digital services on healthcare and social welfare: An umbrella review

BACKGROUND

Digital services can be effective and cost-efficient options for treating non-communicable diseases, but generalizability is limited due to heterogeneous treatment effects. This umbrella review aims to evaluate the impact of digital services on population health, costs, and patient and healthcare professional satisfaction, and to identify facilitators and barriers to using digital services in healthcare and social welfare.

METHODS

The protocol of the study was registered on the 4th of September 2022 to the International Prospective Register of Systematic Reviews, PROSPERO (CRD42022355635). The review was performed using the Centre for Reviews and Dissemination, Cochrane, Ovid Medline, Scopus, and Web of Science in June 2022. The methodological quality of the included reviews was assessed. The impact of digital services was categorized as no evidence, no dominance, and mixed and positive effect. Inductive content analysis was used to identify facilitators and barriers.

RESULTS

A total of 66 studies were included in the review, 64 % of which were evaluated as high quality. Studies on the impact of digital services in social welfare were not identified. Sixty-five percent of reviews evaluated the impact of digital services on population health with mixed effects; 21 % were on costs with mixed effects; 27 % were on patient satisfaction with positive effects; and 7.6 % were on healthcare professionals' satisfaction with mixed effects. Various features, allocation, end-user support, organized services, and service development facilitated the use of digital services. Correspondingly, barriers were related to service limitations, digital competency, funding- and service strategies, resources and change management.

CONCLUSIONS

Compared to usual care, digital services had a mixed impact on population health and costs with high satisfaction in patients. Mixed healthcare professionals' satisfaction was associated with the use of digital services, and it was less studied. To ensure successful implementation and sustainability of digital services, attention must be paid to address barriers and supporting facilitators at all levels.

Evidence-based telehealth interventions for posttraumatic stress disorder, depression, and anxiety: A systematic review and meta-analysis

INTRODUCTION

The goal of this systematic review was to examine the efficacy of behavioral health care treatments for posttraumatic stress disorder (PTSD), depression, and anxiety delivered via telehealth.

METHODS

We searched a combination of keywords related to telehealth, relevant mental health disorders, and evidence-based psychotherapies in three databases (PubMed, PsycInfo, and Embase) from database inception to April 2022. We included randomized controlled trials published in English wherein at least one arm received an evidence-based psychotherapy via telehealth. To be included, studies also had to enroll an adult population with symptoms or diagnosis of PTSD, depressive disorder, or anxiety disorder.

RESULTS

Moderate quality of evidence was consistent with only small differences, if any, in efficacy between video teleconferencing (VTC) and in-person delivery for patients with PTSD (d = 0.06, 95% CI -0.17, 0.28). However, for those with depression, in-person delivery was associated with better outcomes compared to VTC (d = 0.28, 95% CI 0.03, 0.54; low quality of evidence). We also found that evidence-based treatments delivered over telephone were more efficacious for depression compared to treatment as usual (d = -0.47, 95% CI -0.66, -0.28; very low quality of evidence). Very low quality of evidence supported the use of telehealth versus waitlist for anxiety (d = -0.48, 95% CI -0.89, -0.09).

CONCLUSIONS

A synthesis across 29 studies indicates that the efficacy of telehealth for delivery of evidence-based behavioral health interventions varies by target diagnosis and telehealth modality. More research is needed on the efficacy of telehealth treatments for depression and anxiety.

Massed v. standard prolonged exposure therapy for PTSD in military personnel and veterans: 12-month follow-up of a non-inferiority randomised controlled trial

BACKGROUND

The utilisation of massed therapy for treating posttraumatic stress disorder (PTSD) is gaining strength, especially prolonged exposure. However, it is unknown whether massed prolonged exposure (MPE) is non-inferior to standard prolonged exposure (SPE) protocols in the long term. The current study aimed to assess whether MPE was non-inferior to SPE at 12 months post-treatment, and to ascertain changes in secondary measure outcomes.

METHODS

A multi-site non-inferiority randomised controlled trial (RCT) compared SPE with MPE in 12 clinics. The primary outcome was PTSD symptom severity (CAPS-5) at 12 months post-treatment commencement. Secondary outcome measures included symptoms of depression, anxiety, anger, disability, and quality of life at 12 weeks and 12 months post-treatment commencement. Outcome assessors were blinded to treatment allocation. The intention-to-treat sample included 138 Australian military members and veterans and data were analysed for 134 participants (SPE = 71, MPE = 63).

RESULTS

Reductions in PTSD severity were maintained at 12 months and MPE remained non-inferior to SPE. Both treatment groups experienced a reduction in depression, anxiety, anger, and improvements in quality of life at 12 weeks and 12 months post-treatment commencement. Treatment effects for self-reported disability in the SPE group at 12 weeks were not maintained, with neither group registering significant effects at 12 months.

CONCLUSIONS

The emergence of massed protocols for PTSD is an important advancement. The current study provides RCT evidence for the longevity of MPE treatment gains at 12 months post-treatment commencement and demonstrated non-inferiority to SPE. Promisingly, both treatments also significantly reduced the severity of comorbid symptoms commonly occurring alongside PTSD.

The Impact of Virtual Consultations on the Quality of Primary Care: Systematic Review

BACKGROUND

The adoption of virtual consultations, catalyzed by the COVID-19 pandemic, has transformed the delivery of primary care services. Owing to their rapid global proliferation, there is a need to comprehensively evaluate the impact of virtual consultations on all aspects of care quality.

OBJECTIVE

This study aims to evaluate the impact of virtual consultations on the quality of primary care.

METHODS

A total of 6 databases were searched. Studies that evaluated the impact of virtual consultations, for any disease, were included. Title and abstract screening and full-text screening were performed by 2 pairs of investigators. Risk of bias was assessed using the Mixed Methods Appraisal Tool. A narrative synthesis of the results was performed.

RESULTS

In total, 30 studies (5,469,333 participants) were included in this review. Our findings suggest that virtual consultations are equally effective to or more effective than face-to-face care for the management of certain conditions, including mental illness, excessive smoking, and alcohol consumption. Overall, 4 studies indicated positive impacts on some aspects of patient-centeredness; however, a negative impact was noted on patients' perceived autonomy support (ie, the degree to which people perceive those in positions of authority to be autonomy supportive). Virtual consultations may reduce waiting times, lower patient costs, and reduce rates of follow-up in secondary and tertiary care settings. Evidence for the impact on clinical safety is extremely limited. Evidence regarding equity was considerably mixed. Overall, it appears that virtual care is more likely to be used by younger, female patients, with disparities among other subgroups depending on contextual factors.

CONCLUSIONS

Our systematic review demonstrated that virtual consultations may be as effective as face-to-face care and have a potentially positive impact on the efficiency and timeliness of care; however, there is a considerable lack of evidence on the impacts on patient safety, equity, and patient-centeredness, highlighting areas where future research efforts should be devoted. Capitalizing on real-world data, as well as clinical trials, is crucial to ensure that the use of virtual consultations is tailored according to patient needs and is inclusive of the intended end users. Data collection methods that are bespoke to the primary care context and account for patient characteristics are necessary to generate a stronger evidence base to inform future virtual care policies.

A Qualitative Literature Search and Pilot Study of Online Support Groups for Patients With Dementia and Their Carers

The ever-growing group of people living with dementia (PLWD) and their relatives face great challenges. The Covid 19 pandemic has once again placed a particular challenge on this vulnerable group. What started a decade earlier with telephone-based support groups experienced a real push during the pandemic in the form of video-based self-help services. The aim of this qualitative literature search in MEDLINE, EMBASE, CINAHL, and PsycINFO with keywords related to online, support group, caregiver, and dementia was to collect the reported experiences by the end of 2022. Peer reviewed journal papers were included when published and written in English. After the joint decision of two reviewers, it was decided to only include studies that were published in Medline. The results of the literature search are compared with experiences of the participants in a presentation group that was transformed into an online group at the time of the COVID-19 pandemic via Zoom. In search yielded a total of 129 articles. 113 articles described different types of interventions, 30 of which had a randomized design. The qualitative literature search showed on the one hand a high interest in online support groups but on the other hand that the effectiveness and efficacy in randomized trials is much less clear. In addition, we investigated the assessments and experiences of the participants in a presentation group that was transformed into an online group at the time of the COVID-19 pandemic via Zoom. This study demonstrates that PLWD and carers on virtual group meetings can express significant emotive capacity and enhanced connectivity with one another despite a diagnosis of mild to moderate dementia. Further research on entry criteria, concerns about online support services in general and necessary support for use is essential to develop the time- and location-independent possibility of video-based online self-help into an important form of support for both PLWD and their caregivers as an additional support option independent of exceptional pandemic situations.
