Monitoring Depression Treatment Outcomes With the Patient Health Questionnaire-9

Freely Generated Word Responses Analyzed With Artificial Intelligence Predict Self-Reported Symptoms of Depression, Anxiety, and Worry

BACKGROUND

Question-based computational language assessments (QCLA) of mental health, based on self-reported and freely generated word responses and analyzed with artificial intelligence, is a potential complement to rating scales for identifying mental health issues. This study aimed to examine to what extent this method captures items related to the primary and secondary symptoms associated with Major Depressive Disorder (MDD) and Generalized Anxiety Disorder (GAD) described in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5). We investigated whether the word responses that participants generated contained information of all, or some, of the criteria that define MDD and GAD using symptom-based rating scales that are commonly used in clinical research and practices.

METHOD

Participants (N = 411) described their mental health with freely generated words and rating scales relating to depression and worry/anxiety. Word responses were quantified and analyzed using natural language processing and machine learning.

RESULTS

The QCLA correlated significantly with the individual items connected to the DSM-5 diagnostic criteria of MDD (PHQ-9; Pearson's r = 0.30-0.60, p < 0.001) and GAD (GAD-7; Pearson's r = 0.41-0.52, p < 0.001; PSWQ-8; Spearman's r = 0.52-0.63, p < 0.001) for respective rating scales. Items measuring primary criteria (cognitive and emotional aspects) yielded higher predictability than secondary criteria (behavioral aspects).

CONCLUSION

Together these results suggest that QCLA may be able to complement rating scales in measuring mental health in clinical settings. The approach carries the potential to personalize assessments and contributes to the ongoing discussion regarding the diagnostic heterogeneity of depression.

Self-efficacy training as an adjunct to exercise in a person with progressive multiple sclerosis: a case report

Background: Increasing self-efficacy to exercise and minimizing disease-related barriers has been shown to improve physical activity levels and quality of life (QOL) in persons with multiple sclerosis (MS). Currently, little research has examined exercise self-efficacy in persons with more advanced MS. Purpose: Explore the effects of a self-efficacy plus exercise intervention on physical activity endurance and level, QOL, and fatigue in an individual with advanced MS and low self-efficacy.Methods: The participant was a 60-year-old, severely disabled female with secondary progressive MS and an Expanded Disability Status Score (EDSS) of 8. The 8-week intervention consisted of weekly discussions and MS-related education; four one-on-one sessions with a MS "mentor;" daily journal to record sleep quality, fatigue level, and physical activity. Outcomes included a modified 5-meter walk test (5MWT), MS Impact Scale (MSIS-29), Exercise Self-Efficacy Scale (EX-ES), Modified Fatigue Impact Scale (MFIS), MS Self-Efficacy Scale (MS-SES), Patient Health Questionnaire-9 (PHQ-9), and daily physical activity monitoring. Outcomes were assessed at baseline (week 0), post-intervention (week 8), and 8 weeks post intervention (week 16). The participant continued her regular exercise routine independently throughout the study period.Results: There were notable improvements in EX-ES, MFIS, PHQ-9, MSIS-29 psychological subscale, sleep quality, and morning fatigue ratings post intervention, some of which were retained at follow up.Conclusion: The findings illustrate that an 8-week self-efficacy intervention increased exercise self-efficacy, QOL, and reduced perceived fatigue in a severely disabled individual with progressive MS. Future research should examine self-efficacy interventions in a larger sample size of persons with progressive MS.

The longitudinal association between depression, anxiety symptoms and HIV outcomes, and the modifying effect of alcohol dependence among ART clients with hazardous alcohol use in Vietnam

INTRODUCTION

Mental health disorders may negatively impact HIV outcomes, such as viral suppression (VS) and antiretroviral (ART) adherence among people with HIV (PWH) with hazardous alcohol use. This study evaluates the longitudinal association between depression, anxiety symptoms, VS and complete ART adherence among ART clients with hazardous alcohol use in Vietnam; and examines alcohol dependence as a modifier in this association.

METHODS

This was a secondary data analysis of a trial for hazardous drinking ART clients in Thai Nguyen, Vietnam. From March 2016 to May 2018, 440 ART clients with an Alcohol Use Disorders Identification Test-Concise (AUDIT-C) score ≥4 for men and ≥3 for women were enrolled. Individuals were randomized to either a combined intervention, a brief intervention or a standard of care. Data on sociodemographics, depression, anxiety symptoms, alcohol use, VS and ART adherence were collected at baseline, three, six, and twelve months. Generalized estimating equation models controlling for intervention exposure were used to estimate time-lagged associations. Risk ratios were estimated using Poisson regression with robust variance estimation.

RESULTS

The mean age of participants was 40.2. The majority was male (96.8%), had at least some secondary school education (85.0%) and had a history of injection drug use (80.9%). No overall effect of depression and anxiety symptoms on VS was observed. When stratified by time, increased anxiety symptoms at six months were associated with VS at 12 months (adjusted risk ratio (aRR) = 1.09; 95% CI 1.02 to 1.17). An increase in depression or anxiety symptoms was associated with a decreased probability of complete ART adherence (depression symptoms: aRR = 0.95; 95% CI: 0.91 to 0.99; anxiety symptoms: aRR = 0.93; 85% CI: 0.88 to 0.99). The negative effects of anxiety symptoms on ART adherence were stronger among participants with alcohol dependence, compared to those without.

CONCLUSIONS

Depression and anxiety symptoms had no overall effect on VS, although they were associated with a lower probability of complete ART adherence. Interventions focusing on mental healthcare for PWH with hazardous alcohol use are needed, and integration of mental healthcare and alcohol reduction should be implemented in HIV primary care settings.

Patient Activation, Depressive Symptoms, and Self-Rated Health: Care Management Intervention Effects among High-Need, Medically Complex Adults

The purpose of this randomized controlled trial (n = 268) at a Federally Qualified Health Center was to evaluate the outcomes of a care management intervention versus an attention control telephone intervention on changes in patient activation, depressive symptoms and self-rated health among a population of high-need, medically complex adults. Both groups had similar, statistically significant improvements in patient activation and self-rated health. Both groups had significant reductions in depressive symptoms over time; however, the group who received the care management intervention had greater reductions in depressive symptoms. Participants in both study groups who had more depressive symptoms had lower activation at baseline and throughout the 12 month study. Findings suggest that patients in the high-need, medically complex population can realize improvements in patient activation, depressive symptoms, and health status perceptions even with a brief telephone intervention. The importance of treating depressive symptoms in patients with complex health conditions is highlighted.

Association of depression symptom severity with short-term risk of an initial hospital encounter in adults with major depressive disorder

BACKGROUND

Despite the availability of pharmacologic and nonpharmacologic treatment options, depression continues to be one of the leading causes of disability worldwide. This study evaluated whether depression symptom severity, as measured by PHQ-9 score, of patients diagnosed with MDD is associated with short-term risk of a hospital encounter (ER visit or inpatient stay).

METHODS

Adults with ≥1 PHQ-9 assessment in an outpatient setting (index date) and ≥ 1 MDD diagnosis within 6 months prior were included from the de-identified Optum Electronic Health Record database (April 2016-June 2019). Patients were categorized by depression symptom severity based on PHQ-9 scores obtained by natural language processing. Crude rates, adjusted absolute risks, and adjusted relative risks of all-cause and MDD-related hospital encounters within 30 days following assessment of depression severity were determined.

RESULTS

The study population consisted of 280,145 patients with MDD and ≥ 1 PHQ-9 assessment in an outpatient setting. Based on PHQ-9 scores, 26.9% of patients were categorized as having none/minimal depression symptom severity, 16.4% as mild, 24.7% as moderate, 19.6% as moderately severe, and 12.5% as severe. Among patients with none/minimal, mild, moderate, moderately severe, and severe depression, the adjusted absolute short-term risks of an initial all-cause hospital encounter were 4.1, 4.4, 4.8, 5.6, and 6.5%, respectively; MDD-related hospital encounter adjusted absolute risks were 0.8, 1.0, 1.3, 1.6, and 2.1%, respectively. Compared to patients with none/minimal depression symptom severity, the adjusted relative risks of an all-cause hospital encounter were 1.60 (95% CI 1.50-1.70) for those with severe, 1.36 (1.29-1.44) for those with moderately severe, 1.18 (1.12-1.25) for those with moderate, and 1.07 (1.00-1.13) for those with mild depression symptom severity.

CONCLUSIONS

These study findings indicate that depression symptom severity is a key driver of short-term risk of hospital encounters, emphasizing the need for timely interventions that can ameliorate depression symptom severity.

Depression-related stigma among primary care providers

Introduction

Depression is one of the most common mental illnesses in the United States and is often treated in primary care settings. Despite its prevalence, depression remains underdiagnosed and undertreated for a variety of reasons, including stigma. This may result in suboptimal management of depression. Studies evaluating stigma in US primary care providers (PCP) are scarce. The main objective of this study was to describe stigma in a cohort of PCPs.

Methods

We utilized a validated questionnaire to measure stigma (score range 15 to 75 with lower scores indicating lower stigma levels). PCPs in 2 academic internal medicine clinics were sent an electronic questionnaire and received a small monetary incentive for responding. In addition to the stigma survey, we collected demographic data, including age, provider type, gender, and other data related to social proximity to mental illness. To describe stigma, differences in stigma between provider characteristics were evaluated using t tests and ANOVA tests as appropriate.

Results

Of 107 PCPs, 71 responded (66.4% response rate). Male responders displayed higher stigma scores than females (31.8 vs 27.4, P = .0021). Medical residents displayed higher stigma scores than nonresidents (31.3 vs 27.2, P = .0045). Providers with personal exposure to mental illness and those who reported they frequently treated depression had less stigma.

Discussion

Overall, a range of stigma was present among PCPs surveyed. Higher levels of stigma were found in men, medical residents, those without personal exposure to mental illness, younger PCPs, and those who reported treating depression less frequently. Future studies should utilize larger sample sizes and focus on the impact of stigma on quality of care.

Determinants of pain interference and headache impact in patients who have chronic migraine with medication overuse: Results from the MOTS trial

OBJECTIVE

"Pain interference" and "headache impact" refer to negative consequences that pain and headache have on one's life. This study investigated determinants of these negative impacts in a large patient cohort who have chronic migraine with medication overuse.

METHODS

Six hundred and eleven adults were enrolled from 34 headache, neurology, and primary care clinics. Negative consequences of chronic migraine with medication overuse were determined using the Patient-Reported Outcomes Measurement Information System (PROMIS) Pain Interference 6b questionnaire and the Headache Impact Test 6. Relationships between PROMIS-6b and Headache Impact Test 6 scores with demographics, headache characteristics, medication use, anxiety symptoms, and depression symptoms were assessed with linear regression. Elastic Net regression was used to develop a multiple regression model.

RESULTS

PROMIS-6b T-Scores averaged 65.2 (SD 5.4) and Headache Impact Test 6 scores averaged 65.0 (SD 5.3), indicating severe negative consequences of chronic migraine with medication overuse. Chronic migraine with medication overuse interfered with enjoyment of life, concentration, daily activities, doing tasks away from home, and socializing. Depression symptom severity had the strongest relationship with pain interference and headache impact. Moderate-to-severe headache frequency, headache intensity, and anxiety symptoms were also associated with pain interference and headache impact.

CONCLUSIONS

Chronic migraine with medication overuse is associated with substantial negative consequences, the extent of which is most strongly related to depression symptoms.

Association between operational positive depression symptom screen scores on hospital admission and 30-day readmissions

BACKGROUND

Positive scores on inpatient depression symptom screens have been found to be associated with readmissions, yet most studies have used depression screens collected as part of research studies.

OBJECTIVE

We evaluated whether the relationship between depression severity and readmission persisted when depression screening data was obtained for operational purposes.

DESIGN

Retrospective analysis studying prospective use of PHQ data.

SETTING

Large academic medical center.

INTERVENTION

Ward nurses obtained depression screens from patients soon after admission. Patients who answered 'yes' to at least one Patient Health Questionnaire (PHQ)-2 question were screened using the PHQ-9.

MAIN OUTCOMES AND MEASURES

We examined the association between depression severity and 30-day readmissions using logistic regression, adjusting for known predictors of hospital readmission.

RESULTS

From July 2014-June 2016, 18,792 discharged adult medicine inpatients received an initial depression screen (PHQ-2) and 1105 patients (5.90%) had at least one positive response. Of this group, 3163 patients (6.32%) were readmitted within 30 days. 1128 patients received the PHQ-9. Compared to patients with no depression, patients with moderately-severe depression had 3.03 higher odds (95%CI, 1.44-6.38) and patients with severe depression had 1.63 higher odds (95%CI, 0.70-3.78) of being readmitted, after adjusting for known predictors of hospital admission. Adding PHQ-9 results did not significantly improve the predictive power of a readmissions model.

CONCLUSIONS

Our mixed results call into question whether PHQ data obtained for operational purposes may differ compared to data obtained for research purposes. Differences in training of screening staff or patient discomfort with discussing depression in the hospital could explain our findings.

A therapist-guided smartphone app for major depression in young adults: A randomized clinical trial

BACKGROUND

Meru Health Program (MHP) is a therapist-guided, 8-week intervention for depression delivered via smartphone. The aim was to test its efficacy in patients with clinical depression in a Finnish university student health service.

METHODS

Patients (n=124, women 72.6%, mean age 25y) were stratified based on antidepressant status, and randomized into intervention group receiving MHP plus treatment as usual (TAU), and control group receiving TAU only. Depression, measured by the Patient Health Questionnaire-9 (PHQ-9) scale, was the primary outcome. After baseline (T0), follow-ups were at mid-intervention (T4), immediately post-intervention (T8); 3 months (T20), and 6 months (T32) post-intervention.

RESULTS

The intervention group and control group did not have significant differences in depression outcomes throughout end of treatment and follow-up. Among secondary outcomes, increase in resilience (d=0.32, p=0.03) and mindfulness (d=0.57, p=0.002), and reduction in perceived stress (d=-0.52, p=0.008) were greater in MHP+TAU versus TAU at T32; no differences were found in anxiety, sleep disturbances, and quality of life between groups. Post-hoc comparisons of patients on antidepressants showed significantly greater reduction in depression at T32 for MHP+TAU versus TAU (d=-0.73, p=0.01); patients not on antidepressants showed no between-group differences.

LIMITATIONS

Limitations include unknown characteristics of TAU, potential bias from patients and providers not being blinded to treatment group, and failure to specify examination of differences by antidepressant status in the protocol.

CONCLUSIONS

Most outcomes, including depression, did not significantly differ between MHP+TAU and TAU. Exploratory analysis revealed intervention effect at the end of the 6-month follow-up among patients on antidepressant medication.

Depression

Most psychiatric care is delivered in primary care settings, where depression is the most common presenting psychiatric symptom. Given the high prevalence of depression worldwide and the well-established consequences of untreated depression, the ability of primary care clinicians to effectively diagnose and treat it is critically important. This article offers up-to-date guidance for the diagnosis and treatment of major depressive disorder, including practical considerations for delivering optimal and efficient care for these patients.

Differential Association of Spirituality and Religiosity With Rumination: Implications for the Treatment of Depression

ABSTRACT

Recent studies have shown that religiosity (R) is associated with lower rates of depression, whereas spirituality (S) is associated with higher rates. Rumination has also been associated with higher rates of depression. Some have hypothesized that rumination mediates the differential association of religiosity and spirituality with depression. We empirically test this hypothesis in a longitudinal, multigenerational sample through associations between rumination and depression, R/S and depression, and R/S and rumination. Cross-sectionally, total rumination scores were predicted by spirituality (standardized β = 0.13; 95% confidence interval [CI], 0.00-0.26), with subscale (reflection, depression, and brooding) standardized betas ranging from 0.11 to 0.15 (95% CI, -0.03 to -0.29). Cross-sectionally, rumination was not predicted by religiosity. Longitudinally, and consistent with previous findings, religiosity, but not spirituality, predicted reduced depressive symptoms (standardized β = -0.3; 95% CI, -0.58 to -0.01). The association between spirituality and rumination was driven by millennials. Psychotherapies that target rumination for depression might therefore be especially effective in the millennial demographic.

The Minimum Clinically Important Difference for Patient Health Questionnaire-9 in Minimally Invasive Transforaminal Interbody Fusion

STUDY DESIGN

Retrospective cohort.

OBJECTIVE

To investigate and establish minimum clinically important differences (MCID) for Patient Health Questionnaire-9 (PHQ-9) among patients undergoing minimally invasive transforaminal lumbar interbody fusion (MIS TLIF).

SUMMARY OF BACKGROUND

Spine surgery is linked to postoperative improvements in anxiety, depression, and mental health. These improvements have been documented using patient-reported outcome measures such as PHQ-9. Few studies evaluated the clinical significance of PHQ-9 for lumbar spine surgery.

METHODS

Patients who underwent single-level, primary MIS TLIF from 2015 to 2017 were retrospectively reviewed in a prospective database. Patients with incomplete preoperative and 2-year postoperative PHQ-9 surveys were excluded. Demographic and perioperative characteristics were recorded. PHQ-9, 12-Item Short Form (SF-12), and Veterans RAND 12-Item Health Survey (VR-12) Mental Component Summary (MCS) were collected at preoperative, 6-week, 12-week, 6-month, 1-year, and 2-year intervals. MCID was calculated using anchor and distribution-based methods. SF-12 served as an anchor. MCID was assessed using mean change methodology, four receiver operating characteristic curve assessments, and standard error measurement. Cutoff values were selected from receiver operating characteristic curve analysis. MCID achievement rates for all patient-reported outcome measures were calculated.

RESULTS

A total of 139 patients met inclusion criteria, with a mean age of 55 years and 39% females. The most common spinal pathology was radiculopathy (92%). MCID analysis revealed the following ranges of values: 2.0 to 4.8 (PHQ-9), 6.7 to 12.1 (SF-12 MCS), and 7.5 to 15.9 (VR-12 MCS). Final MCID thresholds were 3.0 (PHQ-9), 9.1 (SF-12 MCS), and 8.1 (VR-12 MCS). MCID achievement at 2-years for PHQ-9, SF-12 MCS, and VR-12 MCS was 89.2%, 85.6%, and 84.9% respectively.

CONCLUSION

Our 2-year postoperative MCID analysis is the first mental health calculation from an MIS TLIF cohort. We report a 2-year MCID value for PHQ-9 of 3.0 (2.0-4.8). MCID values for mental health instruments are important for determining overall success of lumbar spine surgery.Level of Evidence: 3.

Trajectories of depression and anxiety symptoms during the COVID-19 pandemic in a representative Australian adult cohort

Objectives

To estimate initial levels of symptoms of depression and anxiety, and their changes during the early months of the COVID‐19 pandemic in Australia; to identify trajectories of symptoms of depression and anxiety; to identify factors associated with these trajectories.

Design, setting, participants

Longitudinal cohort study; seven fortnightly online surveys of a representative sample of 1296 Australian adults from the beginning of COVID‐19‐related restrictions in late March 2020 to mid‐June 2020.

Main outcome measures

Symptoms of depression and anxiety, measured with the Patient Health Questionnaire (PHQ‐9) depression and Generalised Anxiety Disorder (GAD‐7) scales; trajectories of symptom change.

Results

Younger age, being female, greater COVID‐19‐related work and social impairment, COVID‐19‐related financial distress, having a neurological or mental illness diagnosis, and recent adversity were each significantly associated with higher baseline depression and anxiety scores. Growth mixture models identified three latent trajectories for depression symptoms (low throughout the study, 81% of participants; moderate throughout the study, 10%; initially severe then declining, 9%) and four for anxiety symptoms (low throughout the study, 77%; initially moderate then increasing, 10%; initially moderate then declining, 5%; initially mild then increasing before again declining, 8%). Factors statistically associated with not having a low symptom trajectory included mental disorder diagnoses, COVID‐19‐related financial distress and social and work impairment, and bushfire exposure.

Conclusion

Our longitudinal data enabled identification of distinct symptom trajectories during the first three months of the COVID‐19 pandemic in Australia. Early intervention to ensure that vulnerable people are clinically and socially supported during a pandemic should be a priority.

Prevalence of depressive symptoms among older children and young adolescents: a longitudinal population-based study

Introduction

This paper investigates levels of depressive symptoms among older children and young adolescents, 11-14 years of age. The population-based sample was assessed twice during a 12-month period. Point-prevalence, 12-month prevalence, and 12-month incidence were measured by a validated self-reported scale (SFMQ) and are presented in this paper.

Methods

A total of 2148 pupils were invited to participate in this study, and 1748 pupils and at least one parent/guardian provided informed consent. The population was assessed twice within one 12-month period resulting in 1439 participants at both data collection points. Depressive symptoms were measured by a validated self-reported scale, The Short Mood and Feelings Questionnaire (SMFQ).

Results

The results indicate that the point-prevalence was just under 10% in 6^th to 10^th grade with a 12-month prevalence at almost 3%. The results also indicate an incidence rate of 4.5% over 12-months. This study confirms that girls report a higher range of point prevalence, 12- month-prevalence, and 12-month incidence compared to boys.

Conclusions

The results indicate that depressive symptoms among children and young adolescents is a serious health challenge. The results demonstrate substantial gender differences even at an early age (11-14 years), where girls report significantly higher point prevalence, 12-month-prevalence, and 12-month incidence compared to boys. Results from this study suggest that depressive symptoms are an important problem that young adolescents face, and the study underlines the need for more intervention tailored to gender at the middle-school level, especially with respect to those children and adolescents who experience persistent depressive symptoms.

Older adults in skilled nursing facilities demonstrate low physical activity during and after discharge

PURPOSE

This study sought to quantify physical activity and sedentary time among older adults during a skilled nursing facility (SNF) stay and after the transition home, a critical period when patients are at high risk for adverse events.

MATERIALS AND METHODS

We performed an observational cohort study of physical activity and sedentary behavior during the last 3-5 days before discharge from SNF and the initial 3-5 days at home using accelerometers. Participants answered questions about perceived physical activity in the SNF and at home.

RESULTS

A convenience sample of thirty-one residents from two SNFs were included. Participants spent a median 12.2% (interquartile range [IQR], 17.3%) of time upright in the SNF and 16.8% (IQR, 15.2%) of their time upright at home (p = 0.002) and took a median of 849 steps (IQR, 1772) in the SNF and 922 steps (IQR, 1906) at home (p = 0.57), per day. Participants averaged fewer sitting bouts at home (p = 0.03), but there was no difference in sit-to-stand transitions (p = 0.32) or activity scores (p = 0.67). Subjective perceptions of physical activity appeared to be higher than objective measurements.

CONCLUSION

In an exploratory study, SNF residents demonstrated profoundly low levels of physical activity both during and after their SNF stay. Future studies using larger sample sizes should examine physical activity during the SNF to home transition as well as barriers and facilitators to physical activity in post-acute care environments.IMPLICATIONS FOR REHABILITATIONSNF residents in this study demonstrated low levels of physical activity and high rates of sedentary behavior that persisted after discharge home.Interventions to improve physical activity levels in the SNF are sorely needed, and those interventions should include a plan for progressing physical activity after the transition home.Objective measurement of physical activity using activity monitors may prove clinically useful for older adults following hospitalization in the SNF and home settings.

Circulating cytokines as predictors of depression in patients with breast cancer

Depression is a common comorbid disorder associated with breast cancer, and it can have considerable physical and psychological impacts. Circulating cytokines have been proposed as a potential tool to predict depression in various diseases; however, limited studies have specifically examined it in breast cancer. In this study, we examined and compared the prediction ability of various circulating cytokines for depression in patients with breast cancer. Eighty-three patients with a new diagnosis of breast cancer not receiving chemotherapy were recruited; among them, 15 patients had depression and 68 did not have depression. Depression was evaluated using the Patient Health Questionnaire 9 (PHQ-9). Cytokine levels in the serum were measured using an immunology multiplex assay. Two types of cytokines were assayed: (1) proinflammatory cytokines (interleukin [IL]-1β, IL-2, IL-6, IL-12, IL-17A, interferon [IFN]γ, and tumor necrosis factor [TNF]α) and (2) anti-inflammatory cytokines (IL-4, IL-5, IL-10, and IL-13). Receiver operating characteristic (ROC) analysis was performed to calculate the area under the curves (AUCs), sensitivities, and specificities of circulating cytokines for predicting depression. As a result, IL-2 (AUC = 0.78) and IL-5 (AUC = 0.76) demonstrated good predictability for depression, even after controlling for the covariates (i.e. age, education, stage of cancer, surgery, radiation therapy, and hormone therapy). The optimal cut-off value of IL-2 for predicting depression was 1.06 pg/mL with a sensitivity of 86.7% and a specificity of 52.9%; this cytokine also had the best prediction ability in this study. Owing to the prediction ability and practical feasibility of circulating cytokines, they may be used as a valid laboratory diagnostic tool for depression in breast cancer.

The Individualized Addictions Consultation Team Residential Program: A Creative Solution for Integrating Care for Veterans With Substance Use Disorders Too Complex for Other Residential Treatment Programs

The Veterans Affairs (VA) healthcare system is one of the main providers of substance use treatment within the United States, and many veterans with a substance use disorder (SUD) present with co-occurring diagnoses or other concerns. Though there has been increasing recognition of the need for integration of treatments for SUD and comorbid mental illness, there have been limited studies of such programs, particularly within the VA healthcare system. To address that gap in the literature, this paper examines treatment outcomes in an integrated model of dual diagnosis residential treatment for veterans: the Individualized Addictions Consultation Team (I-ACT) program. Methods: The current paper draws from clinical outcome evaluation data within a residential treatment program at a large Midwestern VA Medical Center (VAMC). The I-ACT program provides residential substance abuse treatment to individuals with a primary SUD and other factors that interfere with the successful completion of a traditional residential rehabilitation program. Between 2017 and 2018, 130 individuals (97.7% men, average age = 60.62 years) entered the I-ACT program. As part of standard measurement-based care, veterans were administered the Brief Addiction Monitor and the Patient Health Questionnaire-9 at admission and discharge. Results: Most individuals (74.6%) who entered I-ACT completed the residential program (average length of stay 34.2 days). Scores on both measures significantly decreased from intake to discharge (p < .001), with the change in depression scores indicating clinically significant improvement. Those with an additional mental health diagnosis achieved similar decreases in substance use symptoms and had lower depression scores at discharge than those with a SUD alone. Conclusions: Our results indicate that even for veterans who may not benefit from traditional SUD treatment programs, a more integrated and personalized residential program can be effective.

Design of CLARO (Collaboration Leading to Addiction Treatment and Recovery from other Stresses): A randomized trial of collaborative care for opioid use disorder and co-occurring depression and/or posttraumatic stress disorder

INTRODUCTION

Opioid use disorder (OUD) co-occurring with depression and/or posttraumatic stress disorder (PTSD) is common and, if untreated, may lead to devastating consequences. Despite the availability of evidence-based treatments for these disorders, receipt of treatment is low. Even when treatment is provided, quality is variable. Primary care is an important and underutilized setting for treating co-occurring disorders (COD) because OUD, depression and PTSD are frequently co-morbid with medical conditions and most people visit a primary care provider at least once a year. With rising rates of OUD and opioid-related fatalities, this is a critical treatment and quality gap in a vulnerable and stigmatized population.

METHODS

CLARO (Collaboration Leading to Addiction Treatment and Recovery from Other Stresses) is a multi-site, randomized pragmatic trial of collaborative care (CC) for co-occurring disorders in 13 rural and urban primary care clinics in New Mexico to improve care for patients with OUD and co-occurring depression and/or PTSD. CC, a service delivery approach that uses multi-faceted interventions, has not been tested with COD. We will enroll and randomize 900 patients to either CC adapted for COD (CC-COD) or enhanced usual care (EUC) and will collect patient data at baseline, 3-, and 6-month follow-up. Our primary outcomes are medications for OUD (MOUD) access, MOUD continuity of care, depression symptoms, and PTSD symptoms.

DISCUSSION

Although CC is effective for improving outcomes in primary care among patients with mental health conditions, it has not been tested for COD. This article describes the CLARO CC-COD intervention and clinical trial.

A Pragmatic Non-Randomized Trial of Prehabilitation Prior to Cancer Surgery: Study Protocol and COVID-19-Related Adaptations

Background

Experimental data highlight the potential benefits and health system cost savings related to surgical prehabilitation; however, adequately powered randomized controlled trial (RCT) data remain nascent. Emerging prehabilitation services may be informed by early RCT data but can be limited in informing real-world program development. Pragmatic trials emphasize external validity and generalizability to understand and advise intervention development and implementation in clinical settings. This paper presents the methodology of a pragmatic prehabilitation trial to complement emerging phase III clinical trials and inform implementation strategies.

Methods

This is a pilot pragmatic clinical trial conducted in a large academic hospital in Toronto, Ontario, Canada to assess feasibility of clinical implementation and derive estimates of effectiveness. Feasibility data include program referral rates, enrolment and attrition, intervention adherence and safety, participant satisfaction, and barriers and facilitators to programming. The study aims to receive 150 eligible referrals for adult, English-speaking, preoperative oncology patients with an identified indication for prehabilitation (e.g., frailty, deconditioning, malnutrition, psychological distress). Study participants undergo a baseline assessment and shared-decision making regarding the intervention setting: either facility-based prehabilitation or home-based prehabilitation. In both scenarios, participants receive an individualized exercise prescription, stress-reduction psychological support, nutrition counseling, and protein supplementation, and if appropriate, smoking cessation program referrals. Secondary objectives include estimating intervention effects at the week prior to surgery and 30 and 90 days postoperatively. Outcomes include surgical complications, postoperative length of stay, mortality, hospital readmissions, physical fitness, psychological well-being, and quality of life. Data from participants who decline the intervention but consent for research-related access to health records will serve as comparators. The COVID-19 pandemic required the introduction of a 'virtual program' using only telephone or internet-based communication for screening, assessments, or intervention was introduced.

Conclusion

This pragmatic trial will provide evidence on the feasibility and viability of prehabilitation services delivered under usual clinical conditions. Study amendments due to the COVID-19 pandemic are presented as strategies to maintain prehabilitation research and services to potentially mitigate the consequences of extended surgery wait times.

A Portrait of Mental Health Services Utilization and Perceived Barriers to Care in Men and Women Evacuated During the 2016 Fort McMurray Wildfires

This study examines the influence of gender on mental health services utilization and on perceived barriers to treatment one year after the 2016 Fort McMurray wildfires. Data was collected through a phone survey from May to July 2017 (N = 1510). Participants were English-speaking evacuees aged 18 and older. Mental health services utilization and barriers to mental health care were assessed with the Perceived Need for Care questionnaire. Probable diagnoses of posttraumatic stress disorder, depression and insomnia were assessed with validated self-report questionnaires. Multiple logistic regressions confirmed that gender was a significant predictor of services utilization, after controlling for associated sociodemographic variables and presence of probable diagnoses. Women were respectively 1.50, 1.55 and 1.86 times more likely than men to receive information, medication and psychological help. Self-reliance was the most frequently reported reason for not receiving help, and motivational barriers, such as pessimism and stigma, were reported in a higher proportion than structural barriers, including nonresponse and finance. No significant gender differences were found in the types of perceived barriers to services. Among the Fort McMurray fire evacuees, mental health services utilization was similar to other studies on natural disaster victims, and higher in women than in men. Efforts to increase services utilization in natural disaster victims should focus on motivational barriers and offering treatments fostering people's autonomy, such as online treatments.

Clinically meaningful changes on depressive symptom measures and patient-reported outcomes in patients with treatment-resistant depression

OBJECTIVE

To use the Clinical Global Impression-Severity (CGI-S) scale to estimate clinically meaningful and clinically substantial changes as measured using the Montgomery-Åsberg Depression Rating Scale (MADRS), the Sheehan Disability Scale (SDS), and the Patient Health Questionnaire-9 (PHQ-9) in patients with treatment-resistant depression (TRD).

METHODS

Pooled data were derived from two 4-week, randomized, active-controlled studies evaluating esketamine nasal spray (ESK) plus oral antidepressant (OAD) or OAD plus placebo nasal spray (PBO) in adults with TRD (N = 565). CGI-S, MADRS, SDS, and PHQ-9 scores were obtained at baseline and over 4 weeks of treatment. In this post hoc analysis, change scores on the MADRS, SDS, and PHQ-9 that corresponded to a clinically meaningful (1-point) or clinically substantial (2-point) change on the CGI-S scale were identified.

RESULTS

Clinically meaningful changes in CGI-S scores after 28 days corresponded to 6-, 4-, and 3-point changes from baseline on the MADRS, SDS, and PHQ-9, respectively. Similarly, a 2-point CGI-S score change (clinically substantial change) corresponded to a 12-, 8-, and 6-point change on the MADRS, SDS, and PHQ-9, respectively. The proportion of patients showing substantial clinical improvement in the ESK plus OAD group versus the OAD plus PBO group after 28 days of treatment favored ESK plus OAD: 69.0% vs 55.3% (MADRS), 64.5% vs 48.9% (SDS), and 77.1% vs 64.7% (PHQ-9).

CONCLUSION

We provide a basis for identifying clinically meaningful and clinically substantial changes as assessed with commonly used outcome measures for depression to facilitate the translation of clinical trial results into clinical practice.

Application and validation of the bodily distress syndrome checklist in a psychosomatic outpatient sample

OBJECTIVE

The BDS checklist is a self-report measure to assess the most common somatic symptoms in functional somatic syndromes, based on the diagnostic concept of Bodily Distress Syndrome. The aim of the study was to examine the psychometric properties and validity of the BDS checklist in a psychosomatic sample and to investigate whether it is suitable to detect DSM-5 somatic symptom disorders (SSD).

METHOD

In a cross-sectional study, n = 368 patients from a psychosomatic outpatient clinic completed the BDS checklist and a semi-structured clinical interview on SSD. Item and scale characteristics and measures of reliability and validity were determined.

RESULTS

The BDS checklist showed good item characteristics and reliability (Cronbach α = 0.89). Factor analysis confirmed four symptom clusters (CFI = 0.95, TLI = 0.95, RMSEA = 0.091, 90% CI = 0.085-0.097). The BDS total score showed significant correlations with other measures of somatic symptom burden (r = 0.79, p < .001), health anxiety (r = 0.46, p < .001), depression (r = 0.45, p < .001), and general anxiety (r = 0.41, p < .001). Higher BDS checklist scores were associated with higher physical and mental health impairment and higher health care use. Diagnostic accuracy regarding somatic symptom disorder was moderate (AUC = 0.72, 95% CI: 0.67-0.77).

CONCLUSION

Findings of our study indicate that the BDS checklist is a reliable and valid measure to assess the most common somatic symptoms in a psychosomatic setting. It is however not sufficient to detect persons at risk for somatic symptom disorder. A combination with further questionnaires could probably improve diagnostic accuracy.

Loneliness Is Associated with Depressive Affect, But Not with Most Other Symptoms of Depression in Community-Dwelling Individuals: A Network Analysis

There is a strong relationship between loneliness and depression, but depression is a heterogeneous disorder. We examined the profile of depressive symptoms most strongly related to loneliness. Study participants were 2007 community-dwelling individuals (median age 31 years, 70.4% women) who completed an online survey on loneliness (single-item question: “never”, “sometimes”, “often”), depressive symptoms (Patient Health Questionnaire-9) and demographics. The relationship between loneliness and depressive symptoms was evaluated with linear regression and network analyses. The prevalence of loneliness (sometimes or often) and of moderate depression was 47.1% and 24.0%, respectively. Loneliness explained 26% of the variance in the total depressive symptom score (p < 0.001), independent of covariates. This result was almost exclusively explained by the relationship with a single depression symptom (“feeling down, depressed, or hopeless”), irrespective of whether loneliness was treated as a nominal or continuous variable. The findings of our study suggest that the role of loneliness in depression should not only be investigated at the syndrome level, but also at the symptom level. Studies are warranted to test whether targeted treatment of depressive affect is particularly effective against loneliness.

Comparison of different scoring methods based on latent variable models of the PHQ-9: an individual participant data meta-analysis

BACKGROUND

Previous research on the depression scale of the Patient Health Questionnaire (PHQ-9) has found that different latent factor models have maximized empirical measures of goodness-of-fit. The clinical relevance of these differences is unclear. We aimed to investigate whether depression screening accuracy may be improved by employing latent factor model-based scoring rather than sum scores.

METHODS

We used an individual participant data meta-analysis (IPDMA) database compiled to assess the screening accuracy of the PHQ-9. We included studies that used the Structured Clinical Interview for DSM (SCID) as a reference standard and split those into calibration and validation datasets. In the calibration dataset, we estimated unidimensional, two-dimensional (separating cognitive/affective and somatic symptoms of depression), and bi-factor models, and the respective cut-offs to maximize combined sensitivity and specificity. In the validation dataset, we assessed the differences in (combined) sensitivity and specificity between the latent variable approaches and the optimal sum score (⩾10), using bootstrapping to estimate 95% confidence intervals for the differences.

RESULTS

The calibration dataset included 24 studies (4378 participants, 652 major depression cases); the validation dataset 17 studies (4252 participants, 568 cases). In the validation dataset, optimal cut-offs of the unidimensional, two-dimensional, and bi-factor models had higher sensitivity (by 0.036, 0.050, 0.049 points, respectively) but lower specificity (0.017, 0.026, 0.019, respectively) compared to the sum score cut-off of ⩾10.

CONCLUSIONS

In a comprehensive dataset of diagnostic studies, scoring using complex latent variable models do not improve screening accuracy of the PHQ-9 meaningfully as compared to the simple sum score approach.

Feasibility and acceptability of an acceptance and commitment therapy intervention for caregivers of adults with Alzheimer's disease and related dementias

Background

Caregivers of patients with Alzheimer’s disease or a related dementia (ADRD) report high levels of distress, including symptoms of anxiety and depression, caregiving burden, and existential suffering; however, those with support and healthy coping strategies have less stress and burden. Acceptance and Commitment Therapy (ACT) aims to foster greater acceptance of internal events while promoting actions aligned with personal values to increase psychological flexibility in the face of challenges. The objective of this single-arm pilot, Telephone Acceptance and Commitment Therapy Intervention for Caregivers (TACTICs), was to evaluate the feasibility, acceptability, and preliminary effects of an ACT intervention on ADRD caregiver anxiety, depressive symptoms, burden, caregiver suffering, and psychological flexibility.

Methods

ADRD caregivers ≥21 years of age with a Generalized Anxiety Disorder Scale (GAD-7) score ≥ 10 indicative of moderate or higher symptoms of anxiety were enrolled (N = 15). Participants received a telephone-based ACT intervention delivered by a non-licensed, bachelor’s-prepared trained interventionist over 6 weekly 1-h sessions that included engaging experiential exercises and metaphors designed to increase psychological flexibility. The following outcome measures were administered at baseline (T1), immediately post-intervention (T2), 3 months post-intervention (T3), and 6 months post-intervention (T4): anxiety symptoms (GAD-7; primary outcome); secondary outcomes of depressive symptoms (Patient Health Questionnaire–9), burden (Zarit Burden Interview), suffering (The Experience of Suffering measure), psychological flexibility/experiential avoidance (Acceptance and Action Questionnaire-II), and coping skills (Brief COPE).

Results

All 15 participants completed the study and 93.3% rated their overall satisfaction with their TACTICs experience as “completely satisfied.” At T2, caregivers showed large reduction in anxiety symptoms (SRM 1.42, 95% CI [0.87, 1.97], p < 0.001) that were maintained at T3 and T4.

At T4, psychological suffering (SRM 0.99, 95% CI [0.41, 1.56], p = 0.0027) and caregiver burden (SRM 0.79, 95% CI [0.21, 1.37], p = 0.0113) also decreased.

Conclusions

Despite a small sample size, the 6-session manualized TACTICs program was effective in reducing anxiety, suggesting that non-clinically trained staff may be able to provide an effective therapeutic intervention by phone to maximize intervention scalability and reach.

Effect of pain neuroscience education and transcutaneous electrical nerve stimulation on trigeminal postherpetic neuralgia. A case report

Introduction: Postherpetic neuralgia (PHN) is a complex neuropathic painful condition in which pain is a direct consequence of the response to peripheral nerve damage experienced during herpes zoster attack. PHN is the most common chronic complication of herpes zoster and it causes considerable suffering, affecting the physical functioning and psychological well-being of patients. Objective: To describe the effect of a conservative treatment using pain neuroscience education (PNE) and transcutaneous electrical nerve stimulation (TENS) in a patient with trigeminal PHN. Case Description: A 67-year-old woman sought care for pain, dysfunction, and sensory loss in the left jaw. The assessment included: 1) pain, using the numerical pain rating scale (NPRS), pressure pain threshold (PPT), Douleur Neuropathique 4 (DN4), McGill Pain Questionnaire (MPQ), Graded Chronic Pain Scale (GCPS), and classic body charts of the cranial region; 2) somatosensory function, by means of mechanical detection threshold (MDT) and pressure pain threshold (PPT); 3) jaw function, using the Jaw Functional Limitation Scale-20 (JFLS-20); and 4) psychosocial features, by means of the Patient Health Questionnaire-9 (PHQ-9) and the Generalized Anxiety Disorders Questionnaire-7 (GAD-7). Treatment consisted of 12 sessions of PNE and TENS. Outcomes: After treatment, a clinically significant improvement in NPRS, DN4, MDT, GCPS, and PHQ-9 was observed. Conclusion: In this case report, a treatment based on the combination of PNE and TENS seemed to have contributed to improving pain, sensory abnormalities, and jaw function. Psychosocial factors also showed a trend to improve after the treatment.

Prevalence of Depression and Generalized Anxiety Disorder Among Mexican Indigenous Adolescents and Young Adults: Challenges for Healthcare

Providing evidence on mental disorders in indigenous adolescents is critical to achieving universal health coverage (UHC). The prevalence of symptoms of depression and generalized anxiety disorder symptoms were estimated for 2082 adolescents aged 14-20 years in Chiapas, Mexico. Mental disorders were assessed using the 9-item Patient-Health Questionnaire and the 7-item Generalized Anxiety Disorder Scale. Among the adolescents evaluated, 35.8% suffered from depression or generalized anxiety disorder. Of those, 6.1% reported a previous diagnosis. 32.1% of adolescents with both mental disorders reported having attempted suicide. Gender, substance use, adverse living experiences and living conditions were correlated to the presence of depression and/or generalized anxiety disorder. It is mandatory for Mexican health authorities to develop effective instruments aiming to screen and diagnose mental health conditions in adolescents, as well as to provide timely treatment in primary health-care units.

Dissecting the Association Between Inflammation, Metabolic Dysregulation, and Specific Depressive Symptoms: A Genetic Correlation and 2-Sample Mendelian Randomization Study

IMPORTANCE

Observational studies highlight associations of C-reactive protein (CRP), a general marker of inflammation, and interleukin 6 (IL-6), a cytokine-stimulating CRP production, with individual depressive symptoms. However, it is unclear whether inflammatory activity is associated with individual depressive symptoms and to what extent metabolic dysregulation underlies the reported associations.

OBJECTIVE

To explore the genetic overlap and associations between inflammatory activity, metabolic dysregulation, and individual depressive symptoms.

GWAS DATA SOURCES

Genome-wide association study (GWAS) summary data of European individuals, including the following: CRP levels (204 402 individuals); 9 individual depressive symptoms (3 of which did not differentiate between underlying diametrically opposite symptoms [eg, insomnia and hypersomnia]) as measured with the Patient Health Questionnaire 9 (up to 117 907 individuals); summary statistics for major depression, including and excluding UK Biobank participants, resulting in sample sizes of 500 199 and up to 230 214 individuals, respectively; insomnia (up to 386 533 individuals); body mass index (BMI) (up to 322 154 individuals); and height (up to 253 280 individuals).

DESIGN

In this genetic correlation and 2-sample mendelian randomization (MR) study, linkage disequilibrium score (LDSC) regression was applied to infer single-nucleotide variant-based heritability and genetic correlation estimates. Two-sample MR tested potential causal associations of genetic variants associated with CRP levels, IL-6 signaling, and BMI with depressive symptoms. The study dates were November 2019 to April 2020.

RESULTS

Based on large GWAS data sources, genetic correlation analyses revealed consistent false discovery rate (FDR)-controlled associations (genetic correlation range, 0.152-0.362; FDR P = .006 to P < .001) between CRP levels and depressive symptoms that were similar in size to genetic correlations of BMI with depressive symptoms. Two-sample MR analyses suggested that genetic upregulation of IL-6 signaling was associated with suicidality (estimate [SE], 0.035 [0.010]; FDR plus Bonferroni correction P = .01), a finding that remained stable across statistical models and sensitivity analyses using alternative instrument selection strategies. Mendelian randomization analyses did not consistently show associations of higher CRP levels or IL-6 signaling with other depressive symptoms, but higher BMI was associated with anhedonia, tiredness, changes in appetite, and feelings of inadequacy.

CONCLUSIONS AND RELEVANCE

This study reports coheritability between CRP levels and individual depressive symptoms, which may result from the potentially causal association of metabolic dysregulation with anhedonia, tiredness, changes in appetite, and feelings of inadequacy. The study also found that IL-6 signaling is associated with suicidality. These findings may have clinical implications, highlighting the potential of anti-inflammatory approaches, especially IL-6 blockade, as a putative strategy for suicide prevention.

Associations between baseline demographic, clinical and lifestyle factors, and changes in fatigue, depression, and health-related quality of life in long-term cancer survivors: a cohort study

PURPOSE

To investigate the longitudinal associations between demographic, clinical and lifestyle factors, and changes in patient-reported outcomes (PROs) in cancer survivors 6-9 years post-diagnosis in Western Australia.

METHODS

A total of 290 individuals participated in this study. Three-quarters of participants were female, and 55%, 31%, and 14% were survivors of breast cancer, colon cancer, and non-Hodgkin lymphoma (NHL), respectively. PROs (fatigue, depression, and health-related quality of life (HRQOL)) were reported at two time points (2012-13 and 2017). Descriptive statistics were used to assess the overall changes over time and linear mixed models were used to identify factors associated with changes over time, after adjusting for confounders.

RESULTS

No significant changes were observed in PROs between time point 1 and follow-up at the population level, yet a notable proportion of participants (23% for fatigue, 10% for depression, and 39% for HRQOL) reported a negative minimal clinically important difference (MCID). Being non-Caucasian and having had NHL were associated with negative changes over time. Being obese and having had radiotherapy were related to improved outcomes.

CONCLUSION

Cancer survivors whose levels of fatigue, depression, and quality of life are compromised during cancer treatment may require intervention even 6-9 years post-treatment. Our results suggest particular attention should be paid to those who are non-Caucasian and who have had NHL. This is crucial for providing appropriate care and to support those who are at increased risk of deteriorating naturally over time.

Diabetic ketoacidosis: a canary in the mine for mental health disorders?

BACKGROUND

Recurrent diabetic ketoacidosis (DKA) has been linked to mental health disorders, but less is known about single DKA episodes. Most studies are retrospective, lacking control groups.

AIMS

Prospectively examine psychosocial factors in patients presenting with recurrent or single episode DKA and compare to people who have not had DKA.

METHODS

Case-controlled study (consecutive adult DKA admissions April 2015 to December 2016) at Western Health, Melbourne. Data were prospectively collected regarding: diagnosed mental health disorders, likely depression (PHQ-9 questionnaire), diabetes distress (PAID questionnaire) and presence of adverse social factors. A control group without a history of DKA was also recruited.

RESULTS

Of 123 patients admitted with DKA (164 consecutive episodes), 70 consented to participate and 73 age matched type 1 diabetes controls were recruited. Eleven of 18 (61%) with recurrent DKA had a diagnosed mental health disorder, versus 8 of 42 (19%) in the single episode group (p=0.016). The prevalence of likely depression using PHQ-9 was: recurrent 50%, single 40% and controls 22% (recurrent vs controls, p=0.036, single vs controls, p=0.053). Severe diabetes distress (PAID) was present in 47% of recurrent and 34% of single episode DKA (p=0.387). As a group, DKA patients had significantly more unemployment, illicit drug use and tobacco smoking, a lower level of formal education and less regular medical contact compared to controls.

CONCLUSIONS

Mental health disorders and adverse socio-economic factors appear to be common in patients with DKA. The diagnosis of DKA presents an excellent opportunity to screen for depression and offer appropriate intervention. This article is protected by copyright. All rights reserved.

Efficacy of an Interdisciplinary Intensive Outpatient Program in Treating Combat-Related Traumatic Brain Injury and Psychological Health Conditions

Background: Since 2000, over 413,000 US service members (SM) experienced at least one traumatic brain injury (TBI), and 40% of those with in-theater TBIs later screened positive for comorbid psychological health (PH) conditions, including post-traumatic stress disorder (PTSD), depression, and anxiety. Many SMs with these persistent symptoms fail to achieve a recovery that results in a desirable quality of life or return to full duty. Limited information exists though to guide treatment for SMs with a history of mild TBI (mTBI) and comorbid PH conditions. This report presents the methods and outcomes of an interdisciplinary intensive outpatient program (IOP) in the treatment of SMs with combat-related mTBI and PH comorbidities. The IOP combines conventional rehabilitation therapies and integrative medicine techniques with the goal of reducing morbidity in multiple neurological and behavioral health domains and enhancing military readiness. Methods: SMs (n = 1,456) with residual symptoms from mTBI and comorbid PH conditions were treated in a 4-week IOP at the National Intrepid Center of Excellence (NICoE) at Walter Reed National Military Medical Center (WRNMMC). The IOP uses an interdisciplinary, holistic, and patient-centric rehabilitative care model. Interdisciplinary teams provide a diagnostic workup of neurological, psychiatric, and existential injuries, and from these assessments, individualized care plans are developed. Treatment response was assessed using the Neurobehavioral Symptom Inventory (NSI), PTSD Checklist-Military Version (PCL-M), Satisfaction With Life Scale (SWLS), Patient Health Questionnaire-9 (PHQ-9), Generalized Anxiety Disorder-7 (GAD-7), Epworth Sleepiness Scale (ESS), and Headache Impact Test-6 (HIT-6) and administered at admission, discharge, and at 1, 3, and 6 months post-discharge. Findings: Following treatment in the IOP, the symptomatic patients had statistically significant and clinically meaningful improvements across all outcome measures. The largest effect size was seen with GAD-7 (r = 0.59), followed by PHQ-8 (r = 0.56), NSI (r = 0.55), PCL-M (r = 0.52), ESS (r = 0.50), SWLS (r = 0.49), and HIT-6 (r = 0.42). In cross-sectional follow ups, the significant improvements were sustained at 1, 3, and 6 months post-discharge. Interpretation: This report demonstrates that an interdisciplinary IOP achieves significant and sustainable symptom recovery in SMs with combat-related mTBI and comorbid PH conditions and supports the further study of this model of care in complex medical conditions.

Development and validation of a machine learning algorithm for predicting the risk of postpartum depression among pregnant women

OBJECTIVE

There is a scarcity in tools to predict postpartum depression (PPD). We propose a machine learning framework for PPD risk prediction using data extracted from electronic health records (EHRs).

METHODS

Two EHR datasets containing data on 15,197 women from 2015 to 2018 at a single site, and 53,972 women from 2004 to 2017 at multiple sites were used as development and validation sets, respectively, to construct the PPD risk prediction model. The primary outcome was a diagnosis of PPD within 1 year following childbirth. A framework of data extraction, processing, and machine learning was implemented to select a minimal list of features from the EHR datasets to ensure model performance and to enable future point-of-care risk prediction.

RESULTS

The best-performing model uses from clinical features related to mental health history, medical comorbidity, obstetric complications, medication prescription orders, and patient demographic characteristics. The model performances as measured by area under the receiver operating characteristic curve (AUC) are 0.937 (95% CI 0.912 - 0.962) and 0.886 (95% CI 0.879-0.893) in the development and validation datasets, respectively. The model performances were consistent when tested using data ending at multiple time periods during pregnancy and at childbirth.

LIMITATIONS

The prevalence of PPD in the study data represented a treatment prevalence and is likely lower than the illness prevalence.

CONCLUSIONS

EHRs and machine learning offer the ability to identify women at risk for PPD early in their pregnancy. This may facilitate scalable and timely prevention and intervention, reducing negative outcomes and the associated burden.

Implementing Measurement-Based Care for Depression: Practical Solutions for Psychiatrists and Primary Care Physicians

Measurement-based care (MBC) can be defined as the clinical practice in which care providers collect patient data through validated outcome scales and use the results to guide their decision-making processes. Despite growing evidence supporting the effectiveness of MBC for depression and other mental health conditions, many physicians and mental health clinicians have yet to adopt MBC practice. In part, this is due to individual and organizational barriers to implementing MBC in busy clinical settings. In this paper, we briefly review the evidence for the efficacy of MBC focusing on pharmacological management of depression and provide example clinical scenarios to illustrate its potential clinical utility in psychiatric settings. We discuss the barriers and challenges for MBC adoption and then address these by suggesting simple solutions to implement MBC for depression care, including recommended outcome scales, monitoring tools, and technology solutions such as cloud-based MBC services and mobile health apps for mood tracking. The availability of MBC tools, ranging from paper-pencil questionnaires to mobile health technology, can allow psychiatrists and clinicians in all types of practice settings to easily incorporate MBC into their practices and improve outcomes for their patients with depression.

Social relationships and depression during the COVID-19 lockdown: longitudinal analysis of the COVID-19 Social Study

BACKGROUND

The coronavirus disease 2019 (COVID-19) pandemic led to measures that reduced social contact and support. We explored whether UK residents with more frequent or supportive social contact had fewer depressive symptoms during March-August 2020, and potential factors moderating the relationship.

METHODS

A convenience sample of UK dwelling participants aged ⩾18 in the internet-based longitudinal COVID-19 Social Study completed up to 22 weekly questionnaires about face-to-face and phone/video social contact frequency, perceived social support, and depressive symptoms using the PHQ-9. Mixed linear models examined associations between social contact and support, and depressive symptoms. We examined for interaction by empathic concern, perspective taking and pre-COVID social contact frequency.

RESULTS

In 71 117 people with mean age 49 years (standard deviation 15), those with high perceived social support scored 1.836 (1.801-1.871) points lower on PHQ-9 than those with low support. Daily face-to-face or phone/video contact was associated with lower depressive symptoms (0.258 (95% confidence interval 0.225-0.290) and 0.117 (0.080-0.154), respectively) compared to no contact. The negative association between social relationships and depressive symptoms was stronger for those with high empathic concern, perspective taking and usual sociability.

CONCLUSIONS

We found during lockdown that those with higher quality or more face-to-face or phone/video contact had fewer depressive symptoms. Contact quality was more strongly associated than quantity. People who were usually more sociable or had higher empathy had more depressive symptoms during enforced reduced contact. The results have implications for COVID-19 and potential future pandemic management, and for understanding the relationship between social factors and mental health.

Headache characteristics and burden from chronic migraine with medication overuse headache: Cross-sectional observations from the Medication Overuse Treatment Strategy trial

OBJECTIVE

To describe headache characteristics, medication use, disability, and quality of life in a large patient cohort from the United States who have chronic migraine (CM) and medication overuse headache (MOH).

METHODS

In all, 610 adult patients were enrolled into the Medication Overuse Treatment Strategy trial from 34 healthcare clinics, including headache specialty, general neurology, and primary care clinics. Descriptive statistics characterize baseline demographics, headache characteristics, medication use, disability (Headache Impact Test 6 [HIT-6] and Migraine Functional Impact Questionnaire [MFIQ]), pain interference (PROMIS Pain Interference), and quality of life (EQ-5D-5L). Relationships with headache frequency were assessed.

RESULTS

Mean age was 45 years (SD 13) and 531/608 (87.3%) were females. Mean headache days per 30 was 24.3 (SD 5.5), including 13.6 (SD 7.1) with moderate to severe headache. Daily headaches were reported by 36.1% (219/607) of patients. Acute headache medications were used on 21.5 (SD 7.5) per 30 days. The most commonly overused medications were simple analgesics (378/607, 62% of patients), combination analgesics (246/607, 41%), and triptans (128/607, 21%). HIT-6, MFIQ, PROMIS Pain Interference, and EQ-5D-5L scores demonstrated substantial negative impact from CM with MOH on patient functioning and quality of life. Higher headache frequency was associated with more moderate-severe headache days, more frequent acute headache medication use, greater headache-related disability, and lower quality of life. Only 272/606 (44.9%) were taking migraine preventive medication.

CONCLUSIONS

CM with MOH is associated with a large burden on patients in the United States. Higher headache frequency is associated with greater impact on functioning, pain interference, and quality of life.

Improvements in pain, medication use and quality of life in onabotulinumtoxinA-resistant chronic migraine patients following erenumab treatment - real world outcomes

Background

The CGRP antagonists offer a novel therapeutic approach in migraine. Their utility in patients with severe forms of chronic migraine is a subject of particular interest. We present outcomes of 9 months of erenumab treatment in a cohort of patients with difficult-to-control chronic migraine, all of whom had prior unsatisfactory response to onabotulinumtoxinA.

Methods

We offered erenumab to 98 patients with a prior unsatisfactory response to onabotulinumtoxinA. Eighty of 98 had trialled greater occipital nerve injections (82%), 32/98 peripheral neurostimulation (33%) and 18/98 intravenous dihydroergotamine (18%). Thirty eight of 98 (39%) met the definition of triptan overuse and 43/98 (44%) analgesic overuse. All patients met the EHF criteria for ‘resistant migraine’. Outcome measures (recorded monthly) included days with headache limiting activities of daily living (“red”), not limiting (“amber”), headache free (“green”), and requiring triptans or other analgesics. Quality of life scores - headache impact test 6 (HIT-6), patient health questionnaire 9 (PHQ-9) and pain disability index (PDI) - were also measured.

Results

Mean number of red days improved by − 6.4 days (SE 0.67, 95%CI − 7.7 to − 5.1, p=0.001) at 3 months; − 6.8 days (SE 0.96, 95%CI − 8.80 to − 4.9, p=0.001) at 6 months and − 6.5 days (SE 0.86, 95%CI − 8.3 to − 4.8, p=0.001) at 9 months. Repeated measures ANOVA confirmed improvements in the number of red (p=0.001), green (p=0.001), triptan (p=0.001) and painkiller days (p=0.001) as well as scores of the HIT-6 (p=0.001), PHQ-9 (p=0.001), and PDI (p=0.001) across the duration of study.

Conclusion

We observed improvements in pain, medication use and quality of life in onabotulinumtoxinA-resistant chronic migraine patients following erenumab treatment.

An emergency department medical record review for adolescent intentional self-harm injuries

BACKGROUND

Non-suicidal self-injury and suicide attempts are increasing problems among American adolescents. This study developed a definition for identifying intentional self-harm (ISH) injuries in emergency department (ED) records coded with International Classification of Diseases, 10th Revision, Clinical Modification (ICD-10-CM) codes. The definition is based on the injury-reporting framework proposed by the Centers for Disease Control and Prevention. The study sought to estimate the definition's positive predictive value (PPV), and the proportion of ISH injuries with intent to die (i.e., suicide attempt).

METHODS

The study definition, based on first-valid external cause-of-injury ICD-10-CM codes X71-X83, T14.91, T36-T65, or T71, captured 207 discharge records for initial encounters for ISH in one Kentucky ED. Medical records were reviewed to confirm provider-documented diagnosis for ISH, and identify intent to die or suicide ideation. The PPV of the study definition for capturing provider-documented ISH injuries was reported with its 95% confidence interval (95% CI).

RESULTS

The estimated PPV for the study definition to capture ISH injuries was 88.9%, 95% CI (83.8%, 92.8%). The estimated percentage of ISH with intent to die was 45.9, 95% CI (47.1, 61.0%). The ICD-10-CM code "suicide attempt" (T14.91) captured only 7 cases, but coding guidelines restrict assignment of this code to cases in which the mechanism of the suicide attempt is unknown.

CONCLUSIONS

The proposed case definition supported a robust PPV for ISH injuries. Our findings add to the evidence that the current ICD-10-CM coding system and coding guidelines do not allow identification of ISH with intent to die; modifications are needed to address this issue.

Depression in patients with knee osteoarthritis: risk factors and associations with joint symptoms

BACKGROUND

To describe demographic and clinical factors associated with the presence and incidence of depression and explore the temporal relationship between depression and joint symptoms in patients with symptomatic knee osteoarthritis (OA).

METHODS

Three hundred ninety-seven participants were selected from a randomized controlled trial in people with symptomatic knee OA and vitamin D deficiency (age 63.3 ± 7.1 year, 48.6% female). Depression severity and knee joint symptoms were assessed using the patient health questionnaire (PHQ-9) and the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), respectively, at baseline and 24 months.

RESULTS

The presence and incidence of depression was 25.4 and 11.2%, respectively. At baseline, having younger age, a higher body mass index (BMI), greater scores of WOMAC pain (PR: 1.05, 95%CI:1.03, 1.07), dysfunction (PR: 1.02, 95%CI:1.01, 1.02) and stiffness (PR: 1.05, 95%CI: 1.02, 1.09), lower education level, having more than one comorbidity and having two or more painful body sites were significantly associated with a higher presence of depression. Over 24 months, being female, having a higher WOMAC pain (RR: 1.05, 95%CI: 1.02, 1.09) and dysfunction score (RR: 1.02, 95%CI: 1.01, 1.03) at baseline and having two or more painful sites were significantly associated with a higher incidence of depression. In contrast, baseline depression was not associated with changes in knee joint symptoms over 24 months.

CONCLUSION

Knee OA risk factors and joint symptoms, along with co-existing multi-site pain are associated with the presence and development of depression. This suggests that managing common OA risk factors and joint symptoms may be important for prevention and treatment depression in patients with knee OA.

Geriatric principles for patients with cancer

Cancer is primarily a disease of older persons. Given the heterogeneity of aging, physiological age, rather than chronological age, better expresses the cumulative effect of environmental, medical, and psychosocial stressors, which modifies life expectancy. Comprehensive geriatric assessment, a tool that helps ascertain the physiological age of older individuals, is the gold standard for assessing older adults with cancer. Several international organizations recommend using the geriatric assessment domains to identify unrecognized health problems that can interfere with treatment and predict adverse health-related outcomes, aiding complex treatment decision making. More recently, it has been shown that geriatric assessment-guided interventions improve quality of life and mitigate treatment toxicity without compromising survival. In this review, we discuss the role of comprehensive geriatric assessment in cancer care for older adults and provide the reader with useful information to assess potential treatment risks and benefits, anticipate complications, and plan interventions to better care for older people with cancer.

Pilot Study of Telehealth Delivered Rehabilitative Exercise for Youth With Concussion: The Mobile Subthreshold Exercise Program (MSTEP)

Background: Concussion is common, and up to 30% of youth develop persistent symptoms. Preliminary data suggests treatment with rehabilitative exercise is beneficial, but most programs require frequent in-person visits, which is challenging for youth in rural areas, and has been made more difficult for all youth during the COVID-19 pandemic. We have adapted an exercise intervention to be delivered via telehealth using Zoom and personal fitness devices, which could ensure access to this type of treatment. Objective: The goal of this study was to assess feasibility and acceptability of a telehealth delivered exercise intervention for concussion, the Mobile Subthreshold Exercise Program (MSTEP), and collect pilot data regarding efficacy. Materials and Methods: All youth received the 6-week MSTEP intervention which included wearing a Fitbit and setting exercise heartrate and duration goals weekly over Zoom with the research assistant. Youth completed standardized measures of concussive symptoms (Health Behavior Inventory, HBI), fear-avoidance (Fear of Pain Questionnaire, FOPQ) and health-related quality of life (Pediatric Quality of life Assessment, PedsQL), as well as a structured qualitative exit interview. We examined change in measures over time using mixed effects modeling, controlling for age, sex, prior concussion and duration of symptoms. We coded qualitative interviews using Thematic analysis. Results: We recruited 19 subjects, 79% female with average age 14.3 (SD 2.2) and mean duration of symptoms 75.6 days (SD 33.7). Participants wore the Fitbit on 80% of days, and completed 94% of surveys and 96% of Zoom calls. Concussive symptoms (HBI) decreased significantly over the 6 week intervention (-10.6, 95%CI: -16.0 to -5.1) as did fear-avoidance (-21.6, 95%CI: -29.8 to -13.5). PedsQL improved significantly during the same time period (+15.1, 95%CI: 8.6-21.6). Approximately three-quarters (76%) of youth rated their care as "excellent." Participants appreciated the structure of the guided exercise program and the support of the RA. They also enjoyed being able to track their progress with the Fitbit. Conclusion: This study provides evidence for the feasibility and acceptability of a telehealth delivered rehabilitative exercise intervention for youth with concussion. Further research utilizing a randomized controlled trial is needed to assess efficacy.

The emotional disorders associated with multiple sclerosis

Multiple sclerosis (MS) is associated with a high prevalence of emotional and mood disorders. Emotional disorders may worsen during illness progression and affect the quality of life of patients and their families. MS is often associated with depression, with an increased risk of suicide, poor adherence to treatment, decreased functional status, and quality of life. The diagnosis and treatment of emotional and mood disorders in these patients is often challenging since several symptoms of these disorders overlap with those of MS. Other prevalent emotional disorders in MS include bipolar disorder, anxiety disorders, emotional blunting (apathy), and pseudobulbar affect. Early recognition and treatment of these comorbidities could contribute to the reduction of disability and even to decreased mortality. The aim of this chapter is to provide an up-to-date review of mood and emotional disorders that are often associated with MS, focusing on their epidemiology, clinical features, pathogenesis, assessment, and treatment. The interplay between the psychosocial impact of the chronic disability and the demyelinating structural lesions of the brain in precipitating emotional and mood disorders is discussed, as well as its implications for diagnosis and treatment.

Video-Enhanced Care Management for Medically Complex Older Adults with Cognitive Impairment

OBJECTIVE

This pilot study assessed feasibility of video-enhanced care management for complex older veterans with suspected mild cognitive impairment (CI) and their care partners, compared with telephone delivery.

DESIGN

Pilot randomized controlled trial.

SETTING

Durham Veterans Affairs Health Care System.

PARTICIPANTS

Participants were enrolled as dyads, consisting of veterans aged 65 years or older with complex medical conditions (Care Assessment Need score ≥90) and suspected mild CI (education-adjusted Modified Telephone Interview for Cognitive Status score 20-31) and their care partners.

INTERVENTION

The 12-week care management intervention consisted of monthly calls from a study nurse covering medication management, cardiovascular disease risk reduction, physical activity, and sleep behaviors, delivered via video compared with telephone.

MEASUREMENTS

Dyads completed baseline and follow-up assessments to assess feasibility, acceptability, and usability.

RESULTS

Forty veterans (mean (standard deviation (SD)) age = 72.4 (6.1) years; 100% male; 37.5% Black) and their care partners (mean (SD) age = 64.7 (10.8) years) were enrolled and randomized to telephone or video-enhanced care management. About a third of veteran participants indicated familiarity with relevant technology (regular tablet use and/or experience with videoconferencing); 53.6% of internet users were comfortable or very comfortable using the internet. Overall, 43 (71.7%) care management calls were completed in the video arm and 52 (86.7%) were completed in the telephone arm. Usability of the video telehealth platform was rated higher for participants already familiar with technology used to deliver the intervention (mean (SD) System Usability Scale scores: 65.0 (17.0) vs 55.6 (19.6)). Veterans, care partners, and study nurses reported greater engagement, communication, and interaction in the video arm.

CONCLUSION

Video-delivered care management calls were feasible and preferred over telephone for some complex older adults with mild CI and their care partners. Future research should focus on understanding how to assess and incorporate patient and family preferences related to uptake and maintenance of video telehealth interventions.

The Impact of the COVID-19 Pandemic on Self-Reported Health

BACKGROUND

The pandemic caused by the coronavirus SARS-CoV-2 and the countermeasures taken to protect the public are having a substantial effect on the health of the population. In Germany, nationwide protective measures to halt the spread of the virus were implemented in mid-March for 6 weeks.

METHODS

In May, the impact of the pandemic was assessed in the German National Cohort (NAKO). A total of 113 928 men and women aged 20 to 74 years at the time of the baseline examination conducted 1 to 5 years earlier (53%) answered, within a 30-day period, a follow-up questionnaire on SARS-CoV-2 test status, COVID-19- associated symptoms, and self-perceived health status.

RESULTS

The self-reported SARS-CoV-2 test frequency among the probands was 4.6%, and 344 participants (0.3%) reported a positive test result. Depressive and anxiety-related symptoms increased relative to baseline only in participants under 60 years of age, particularly in young women. The rate of moderate to severe depressive symptoms increased from 6.4% to 8.8%. Perceived stress increased in all age groups and both sexes, especially in the young. The scores for mental state and self-rated health worsened in participants tested for SARS-CoV-2 compared with those who were not tested. In 32% of the participants, however, self-rated health improved.

CONCLUSION

The COVID-19 pandemic and the protective measures during the first wave had effects on mental health and on self-rated general health.

Improving mental health in U.S. Veterans using mHealth tools: A pilot study

Rates of PTSD remain elevated among U.S. Veterans, highlighting a need for innovative management tools. Previous studies have shown mobile apps to have positive effects on PTSD symptoms, but few apps have been examined systematically. This pilot study evaluated the perceived effectiveness and usability of Mindset, a novel mobile app that monitors user stress level via heart rate to encourage e-therapy use. The study sample included 30 community-residing Veterans who completed baseline assessments. They used the Mindset app and associated smartwatch until their approximate 1-month follow-up. Self-reported assessments included pre- and post-deployment experiences; experience with Mindset; and standard screeners for PTSD (PCL-M), anxiety (GAD-7), depression (PHQ-9), and alcohol use problems (AUDIT). Among the 24 participants who completed follow-up interviews, a significant decrease (p < 0.05) was found in PCL-M, PHQ-9, and modified AUDIT scores. Respondents reported moderate to high acceptance and satisfaction with Mindset features, though considerable frustration with the associated smartwatch. These findings highlight mHealth apps such as Mindset as potentially useful tools for PTSD and depression symptom management. These findings are also encouraging in the context of the current COVID-19 pandemic, which may accelerate further innovation and implementation of mHealth technologies to improve mental health self-care.

Does symptom severity matter in stepped and collaborative care for depression?

BACKGROUND

We investigated the differential effectiveness of a stepped and collaborative care model (SCM) vs. treatment as usual (TAU) for primary care patients with various depression severity degrees and explored whether subgroups received distinct evidence-based treatments.

METHODS

Subgroup analyses of a RCT were calculated applying a multiple linear mixed model with the factors 1. group (SCM; TAU), 2. severity ((mild-moderate (MMD); severe depression (SD)) and their interaction, with PHQ-9 as primary outcome. Utilization of treatments was analyzed descriptively.

RESULTS

For the 737 participating patients (SCM: n = 569; TAU: n = 168), availability of data substantially varies between subgroups at 12-month follow-up ranging between 37% and 70%. ITT-analysis (Last-observation-carried-forward) revealed a significant interaction for group x severity [p = 0.036] and a significant difference between groups in symptom reduction for MMD (-3.9; [95% CI: -5.1 to -2.6, p < 0.001; d = 0.64] but not for SD (-1.6; [95% CI: -3.4 to 0.2, p = 0.093; d = 0.27]. Sensitivity analyses (multiple imputation, completer analysis, pattern mixture model) didn`t confirm the interaction effect and showed significant effects for both severity groups with slightly higher effect sizes for MMD. Differences between SCM and TAU in the percentage of patients utilizing depression-specific treatments are larger for MMD.

LIMITATIONS

There was a high proportion of missing values among severely depressed patients, especially in SCM.

CONCLUSION

SCM is effective for both MMD and SD. Utilization patterns might help explain the higher effects for MMD. Various strategies of replacement of missing values lead to slightly divergent results due to selective drop out between severity groups.

Incidental findings in whole-body MR imaging of a population-based cohort study: Frequency, management and psychosocial consequences

OBJECTIVES

Management of incidental findings (IF) remains controversial but highly relevant. Our aim was to assess the frequency, management and psychosocial consequences of IF reporting in a population-based cohort study undergoing whole-body MR imaging.

METHODS

The study was nested in a prospective cohort from a longitudinal, population-based cohort (KORA-FF4) in southern Germany. All MR obtained on 3 T MR scanner were reviewed by board-certified radiologists regarding clinically relevant IF. A baseline and follow-up questionnaires including PHQ-9 were completed prior to and 6-month after to the scan.

RESULTS

Of 400 participants (56.3 ± 9.2years, 58 % male) undergoing whole-body MR, IF were found in 22 % of participants (n = 89); most frequently located in the abdominal sequences. In the pre-scan survey, most participants stated as the motivation that they wanted to "contribute to a scientific purpose" (91 %), while "knowing whether I'm healthy" was the most frequent motivation reported 6 months post-scan (88 %). The desire for IF reporting increased over time (pre- vs. 6-months-post-scan), also for clinically less important IF (72 % vs. 84 %, p = 0.001). Regarding psychosocial impact, a small portion (3.4 %) reported that awaiting the IF report added "definitely" or "very probably" additional stress burden. Of participants with reported IF, 56.8 % classified the results as "very helpful". In the post-scan survey moderate depression was observed in 3.3 % and severe depression in 1.2 %. This did not differ between participants with and without reported IF.

CONCLUSION

In a cohort with whole-body MR imaging, the prevalence of IF was high. Participants considered reporting of IF highly important and added only minor psychological burden.

Repetitive transcranial magnetic stimulation for post-stroke depression: a randomised trial with neurophysiological insight

OBJECTIVE

Despite high incidence of depression after stroke, few trials have investigated the therapeutic efficacy of repetitive transcranial magnetic stimulation (rTMS). Here, we aimed to evaluate clinical benefit of delivering a higher dose of rTMS compared to previous stroke trials. Secondary aims were to document adverse effects and investigate the role of functional connectivity as a potential mechanism of clinical response to rTMS treatment.

METHODS

Eleven chronic stroke survivors were recruited to a double-blind, Sham-controlled, randomised trial to investigate 10 sessions of high-frequency rTMS for depression. Clinical assessments were obtained at baseline, after treatment and a 1-month follow-up. Adverse events were documented at completion of the treatment. Resting electroencephalography recordings were performed at baseline and after treatment to estimate functional connectivity.

RESULTS

There were no differences in baseline characteristics between groups (all p ≥ 0.42). Beck Depression Inventory scores decreased for the Active rTMS group from baseline to 1-month follow-up (p = 0.04), but did not change for the Sham group at post-treatment or follow-up (p ≥ 0.17). Stronger theta frequency functional connectivity between the left frontal cortex and right parietal cortex was associated with lower baseline depression (r = - 0.71, p = 0.05). This network strength increased following Active rTMS, with change in connectivity associated with improvement in BDI scores (r = 0.98, p = 0.001). Adverse events were transient and minor and were not statistically different between groups (p ≥ 0.21).

CONCLUSIONS

Active rTMS significantly improved depression and was well tolerated. The mechanistic role of theta frequency functional connectivity appears worthy of further investigation. The trial was registered on the Australian and New Zealand Clinical Trials Registry (ACTRN12619001303134) on September 23, 2019.
