Global Burden Disease Estimates for Major Depressive Disorders (MDD): A review of diagnostic instruments used in studies of prevalence.

Global Burden of Disease (GBD) estimates have significant policy implications nationally and internationally. Disease burden metrics, particularly for depression, have played a critical role in raising governmental awareness of mental health and in calculating the economic cost of depression. Recently, the World Health Organization ranked depression as the single largest contributor to global disability. The main aim of this paper was to assess the basis upon which GBD prevalence estimates for major depressive disorder (MDD) were made. We identify the instruments used in the 2019 GBD estimates and provide a descriptive assessment of the five most frequently used instruments. The majority of country studies, 356/566 (62.9%), used general mental health screeners or structured/semi-structured interview guides, 98/566 (17.3%) of the studies used dedicated depression screeners, and 112 (19.8%) used other tools for assessing depression. Thus, most of the studies used instruments that were not designed to make a diagnosis of depression or assess depression severity. Our results are congruent with and extend previous research that has identified critical flaws in the data underpinning the GBD estimates for MDD. Despite the widespread promotion of these prevalence estimates, caution is needed before using them to inform public policy and mental health interventions. This is particularly important in lower-income countries where resources are scarce.

Conflicts of Interest in Psychopharmacology Textbooks.

While most medical journals require disclosures of industry payments to authors and editors, there is no requirement for textbooks. In this study we evaluated nine well-known psychopharmacology textbooks to identify payments to their writers and editors. Two-thirds of the textbooks had at least one editor or author who received personal payments from one or more pharmaceutical companies, for a total of 11,021,409 USD paid to 11 of 21 editors/authors over a seven-year period. Much of this money was paid to a single author but 24% of the writers received over 75,000 USD each over this time period. There are several psychopharmacology textbooks authored by writers without apparent financial conflicts of interest. Just as with medical journals, medical textbooks should be transparent about payments made to their authors and editors.

Harmonized Outcome Measures for Use in Depression Patient Registries and Clinical Practice.

Major depressive disorder is a common mental health condition that affects an estimated 16.2 million adults and 3.1 million adolescents in the United States. Yet, a lack of uniformity remains in measurements and monitoring for depression both in clinical practice and in research settings. This project aimed to develop a minimum set of standardized outcome measures relevant to both patients and clinicians that can be collected in depression registries and clinical practice. Twenty-nine depression registries and related data collection efforts were identified and invited to submit outcome measures. Additional measures were identified through literature searches and reviews of quality measures. A multistakeholder panel representing clinicians; payers; government agencies; industry; and medical specialty, health care quality, and patient advocacy organizations categorized the 27 identified measures using the Agency for Healthcare Research and Quality's supported Outcome Measures Framework. The panel identified 10 broadly relevant measures and harmonized definitions for these measures through in-person and virtual meetings. The harmonized measures represent a minimum set of outcomes that are relevant to clinicians and patients and appropriate for use in depression research and clinical practice. Routine and consistent collection of these measures in registries and other systems would support creation of a national research infrastructure to efficiently address new questions, improve patient management and outcomes, and facilitate care coordination.

The Cultural Politics of Mental Illness: Toward a Rights-Based Approach to Global Mental Health.

The movement for global mental health (MGMH) has raised awareness about the paucity of mental health services, particularly in low- and middle-income countries. In response, policies and programs have been developed by the World Health Organization and by the Lancet Commission on global mental health, among other organizations. These policy initiatives and programs, while recognizing the importance of being responsive to local needs and culture, are based on Western biomedical conceptualizations of emotional distress. In the paper, we discuss how a rights-based approach can promote the voice and participation of people with lived experience into the MGMH. We argue that a human rights framework can be enhanced by incorporating the conceptual approaches of critical inquiry and community mental health. We also discuss how rights-based approaches and service-user activism can productively reconfigure Western psychiatric conceptualizations of distress and provide both a moral and empirical justification for a paradigm shift within the MGMH.

Reporting of financial conflicts of interest by Canadian clinical practice guideline producers: a descriptive study.

BACKGROUND: The producers of clinical practice guidelines (CPGs) may not disclose industry funding in their CPGs. We reviewed Canadian national CPGs to examine the existence and disclosure of industry-related organizational funding in the CPGs, financial conflicts of interest of committee members and organizational procedures for managing financial conflicts of interest. METHODS: For this descriptive study, we searched the asset map of the Strategy for Patient-Oriented Research Evidence Alliance and the CPG Infobase for CPGs published between Jan. 1, 2016, and Nov. 30, 2018. Eligible guidelines had to have a national focus and either a first-line drug recommendation or a screening recommendation leading to drug treatment. One investigator reviewed all CPG titles to exclude those that were clearly ineligible. Two reviewers independently reviewed all remaining guidelines and extracted data. We analyzed the data descriptively. RESULTS: We included 21 CPGs: 3 from government-sponsored organizations, 9 from disease or condition interest groups and 9 from medical professional societies. None of the 3 government-sponsored organizations reported industry funding, and none of their committee members disclosed financial conflicts of interest. Among the 18 disease or condition interest groups and medical professional societies, 14 (93%) of the 15 that disclosed funding sources on websites (3 did not disclose) reported organizational funding from industry, but none disclosed this information in the CPGs; 12 (86%) of the 14 with conflict-of-interest disclosure statements in the CPG (4 did not include disclosures) had at least 1 committee member with a financial conflict (mean proportion of committee members with a conflict 56%); and for all 8 CPGs with identifiable chairs or cochairs (chairs or cochairs not reported for 10) at least 1 of these people had a financial conflict of interest. None of the guidelines described a plan to manage organizational financial conflicts of interest. INTERPRETATION: Canadian CPGs are vulnerable to industry influence through funding of producers of guidelines and through the financial conflicts of interest of committee members. The CPG producers that receive industry funding should disclose organizational financial conflicts in the CPGs, should engage independent oversight committees and should restrict voting on recommendations to guideline panelists who have no financial conflicts.

Consistency and sources of divergence in recommendations on screening with questionnaires for presently experienced health problems or symptoms: a comparison of recommendations from the Canadian Task Force on Preventive Health Care, UK National Screening Committee, and US Preventive Services Task Force.

BACKGROUND: Recently, health screening recommendations have gone beyond screening for early-stage, asymptomatic disease to include "screening" for presently experienced health problems and symptoms using self-report questionnaires. We examined recommendations from three major national guideline organizations to determine the consistency of recommendations, identify sources of divergent recommendations, and determine if guideline organizations have identified any direct randomized controlled trial (RCT) evidence for the effectiveness of questionnaire-based screening. METHODS: We reviewed recommendation statements listed by the Canadian Task Force on Preventive Health Care (CTFPHC), the United Kingdom National Screening Committee (UKNSC), and the United States Preventive Services Task Force (USPSTF) as of 5 September 2016. Eligible recommendations focused on using self-report questionnaires to identify patients with presently experienced health problems or symptoms. Within each recommendation and accompanying evidence review we identified screening RCTs. RESULTS: We identified 22 separate recommendations on questionnaire-based screening, including three CTFPHC recommendations against screening, eight UKNSC recommendations against screening, four USPSTF recommendations in favor of screening (alcohol misuse, adolescent depression, adult depression, intimate partner violence), and seven USPSTF recommendations that did not recommend for or against screening. In the four cases where the USPSTF recommended screening, either the CTFPHC, the UKNSC, or both recommended against. When recommendations diverged, the USPSTF expressed confidence in benefits based on indirect evidence, evaluated potential harms as minimal, and did not consider cost or resource use. CTFPHC and UKNSC recommendations against screening, on the other hand, focused on the lack of direct evidence of benefit and raised concerns about harms to patients and resource use. Of six RCTs that directly evaluated screening interventions, five did not report any statistically significant primary or secondary health outcomes in favor of screening, and one trial reported equivocal results. CONCLUSIONS: Only the USPSTF has made any recommendations for screening with questionnaires for presently experienced problems or symptoms. The CTFPHC and UKNSC recommended against screening in all of their recommendations. Differences in recommendations appear to reflect differences in willingness to assume benefit from indirect evidence and different approaches to assessing possible harms and resource consumption. There were no examples in any recommendations of RCTs with direct evidence of improved health outcomes.

Developing a Clinician Friendly Tool to Identify Useful Clinical Practice Guidelines: G-TRUST.

BACKGROUND: Clinicians are faced with a plethora of guidelines. To rate guidelines, they can select from a number of evaluation tools, most of which are long and difficult to apply. The goal of this project was to develop a simple, easy-to-use checklist for clinicians to use to identify trustworthy, relevant, and useful practice guidelines, the Guideline Trustworthiness, Relevance, and Utility Scoring Tool (G-TRUST). METHODS: A modified Delphi process was used to obtain consensus of experts and guideline developers regarding a checklist of items and their relative impact on guideline quality. We conducted 4 rounds of sampling to refine wording, add and subtract items, and develop a scoring system. Multiple attribute utility analysis was used to develop a weighted utility score for each item to determine scoring. RESULTS: Twenty-two experts in evidence-based medicine, 17 developers of high-quality guidelines, and 1 consumer representative participated. In rounds 1 and 2, items were rewritten or dropped, and 2 items were added. In round 3, weighted scores were calculated from rankings and relative weights assigned by the expert panel. In the last round, more than 75% of experts indicated 3 of the 8 checklist items to be major indicators of guideline usefulness and, using the AGREE tool as a reference standard, a scoring system was developed to identify guidelines as useful, may not be useful, and not useful. CONCLUSION: The 8-item G-TRUST is potentially helpful as a tool for clinicians to identify useful guidelines. Further research will focus on its reliability when used by clinicians.

Tripartite conflicts of interest and high stakes patent extensions in the DSM-5.

BACKGROUND: The revision process for and recent publication of the DSM-5 initiated debates about the widening of diagnostic boundaries. The pharmaceutical industry had a major financial stake in the outcome of these debates. This study examines the three-part relationship among DSM panel members, principal investigators (PIs) of clinical trials for new DSM-5 diagnoses, and drug companies. METHODS: Financial conflicts of interest (FCOI) of DSM panel members responsible for some new diagnoses in the DSM-5 and PIs of clinical trials for related drug treatments were identified. Trials were found by searching ClinicalTrials.gov. Patent and revenue information about these drugs was found using the US Food and Drug Administration's Orange Book and manufacturer Annual Reports. RESULTS: Thirteen trials met inclusion criteria (testing drugs for some new DSM disorders). Sixty-one percent of the DSM Task Force members and 27% of Work Group members reported FCOI to the trial drug manufacturers. In 5 of the 13 trials (38%), PIs reported ties other than research funding to the drug manufacturer. In 3 of the trials (23%), a PI had financial ties to the drug manufacturer and was also a DSM panel member who had decision-making authority over the revision process. CONCLUSIONS: These findings suggest that increased transparency (e.g., registration on ClinicalTrials.gov) and mandatory disclosure policies (e.g., the American Psychiatric Association's disclosure policy for DSM-5 panel members) alone may not be robust enough strategies to prevent the appearance of bias in both the DSM revision process as well as clinical decisions about appropriate interventions for DSM disorders.

Undisclosed financial conflicts of interest in DSM-5-TR: cross sectional analysis.

OBJECTIVE: To assess the extent and types of financial ties to industry of panel and task force members of the American Psychiatric Association's Diagnostic and Statistical Manual of Mental Disorders, fifth edition, text revision (DSM-5-TR), published in 2022. DESIGN: Cross sectional analysis. SETTING: Open Payments database, USA. PARTICIPANTS: 92 physicians based in the US who served as members of either a panel (n=86) or task force (n=6) on the DSM-5-TR with information recorded in the Centers for Medicare and Medicaid Services Open Payments database during 2016-19. This period was chosen to include the year that development of the DSM-5-TR began and the three years preceding, a time consistent with previous research on conflicts of interest and consistent with the American Psychiatric Association's disclosure requirements for the fifth revision (DSM-5) of the manual. MAIN OUTCOME MEASURES: Type and amount of compensation the panel and task force members of DSM-5-TR received during 2016-19. RESULTS: After duplicate names had been removed, 168 individuals were identified who served as either panel or task force members of the DSM-5-TR. 92 met the inclusion criteria of being a physician who was based in the US and therefore could be included in Open Payments. Of these 92 individuals, 55 (60%) received payments from industry. Collectively, these panel members received a total of $14.2m (£11.2m; €13m). One third (33.3%) of the task force members had payments reported in Open Payments. CONCLUSIONS: Conflicts of interest among panel members of DSM-5-TR were prevalent. Because of the enormous influence of diagnostic and treatment guidelines, the standards for participation on a guideline development panel should be high. A rebuttable presumption should exist for the Diagnostic and Statistical Manual of Mental Disorders to prohibit conflicts of interest among its panel and task force members. When no independent individuals with the requisite expertise are available, individuals with associations to industry could consult to the panels, but they should not have decision making authority on revisions or the inclusion of new disorders.

Becoming a Phronimos: Evidence-Based Medicine, Clinical Decision Making, and the Role of Practical Wisdom in Primary Care.

There has been much discussion about the overmedicalization of human experience and the problems incurred by overzealous action-oriented medical care. In this paper we describe the Aristotelean virtue of phronesis, or practical wisdom, and discuss how it can be developed by interested clinicians. We argue that becoming a phronimos requires conscious attention to one's practice by using feedback to continually improve. But there must also be judicious adherence to clinical practice guidelines and advocacy for people-as-patients at individual, community, and national levels.

Industry influence on mental health research: depression as a case example.

Emotional distress has been rising since before the COVID-19 pandemic and the public is told that depression is a major public health problem. For example, in 2017 depressive disorders were ranked as the third leading cause of "years lost to disability" and the World Health Organization now ranks depression as the single largest contributor to global disability. Although critical appraisals of the epidemiological data raise questions about the accuracy of population-based depression estimates, the dominance of the medical model and the marketing of psychotropics as "magic bullets," have contributed to a dramatic rise in the prescription of psychiatric drugs. Unfortunately, the pharmaceutical industry's influence on psychiatric research and practice has resulted in over-estimates of the effectiveness of psychotropic medications and an under-reporting of harms. This is because the principles that govern commercial entities are incongruent with the principles that guide public health research and interventions. In order to conduct mental health research and develop interventions that are in the public's best interest, we need non-reductionist epistemological and empirical approaches that incorporate a biopsychosocial perspective. Taking depression as a case example, we argue that the socio-political factors associated with emotional distress must be identified and addressed. We describe the harms of industry influence on mental health research and show how the emphasis on "scaling up" the diagnosis and treatment of depression is an insufficient response from a public health perspective. Solutions for reform are offered.

Why psychiatry needs an honest dose of gentle medicine.

The pharmaceutical industry's influence on psychiatric research and practice has been profound and has resulted in exaggerated claims of the effectiveness of psychotropic medications and an under-reporting of harms. After the regulatory approval of fluoxetine, the pharmaceutical industry began promoting (and continues to promote) a chemical imbalance theory of emotional distress. In the last decade, there has been an increased awareness about the limits of this theory and the risks of psychotropic medications. Nonetheless, the medicalization of distress, the sedimented belief in "magic bullets," and the push to "scale up" mental health treatment have contributed to the meteoric rise in the prescription of psychiatric drugs and of polypharmacy. A major premise of this paper is that the conceptual framework of medical nihilism can help researchers and clinicians understand and address the harms incurred by inflated claims of the efficacy of psychotropic medications. We propose that psychiatry, and the mental health field more generally, adopt a model of 'gentle medicine' with regard to both the diagnosis of and treatment for mental health conditions and focus greater attention on the upstream causes of distress.

Industry effects on evidence: a case study of long-acting injectable antipsychotics.

A vigorously debated issue in the psychiatric literature is whether long-acting injectable antipsychotics (LAIs) show clinical benefit over antipsychotics taken orally. In addressing this question, it is critical that systematic reviews incorporate risk of bias assessments of trial data in a robust way and are free of undue industry influence. In this paper, we present a case analysis in which we identify some of the design problems in a recent systematic review on LAIs vs oral formulations. This case illustrates how evidence syntheses that are shaped by commercial interests may undermine patient-centered models of recovery and care. We offer recommendations that address both the bioethical and research design issues that arise in the systematic review process when researchers have financial conflicts of interest.

Ten years later: a review of the US 2009 institute of medicine report on conflicts of interest and solutions for further reform.

Conflicts of interest (COIs) in healthcare are increasingly discussed in the literature, yet these relationships continue to influence healthcare. Research has consistently shown that financial COIs shape prescribing practices, medical education and guideline recommendations. In 2009, the Institute of Medicine (IOM, now the National Academy of Medicine) published Conflicts of Interest in Medical Research, Practice, and Education-one of the most comprehensive reviews of empirical research on COIs in medicine. Ten years after publication of theIOM's report, we review the current state of COIs within medicine. We also provide specific recommendations for enhancing scientific integrity in medical research, practice, education and editorial practices.
