RESUMO

OBJECTIVE: Despite robust evidence for efficacy of measurement-based care (MBC) in behavioral health care, studies suggest that adoption of MBC is limited in practice. A survey from Blue Cross-Blue Shield of North Carolina was sent to behavioral health care providers (BHCPs) about their use of MBC, beliefs about MBC, and perceived barriers to its adoption. METHODS: The authors distributed the survey by using professional networks and snowball sampling. Provider and clinical practice characteristics were collected. Numerical indices of barriers to MBC use were created. Ordered logistic regression models were used to identify associations among practice and provider characteristics, barriers to MBC use, and level of MBC use. RESULTS: Of the 922 eligible BHCPs who completed the survey, 426 (46%) reported using MBC with at least half of their patients. Providers were more likely to report MBC use if they were part of a large group practice, had MBC training, had more weekly care hours, or practiced in nonmetropolitan settings. Physicians, self-reported generalists, more experienced providers, and those who did not accept insurance were less likely to report MBC use. Low perceived clinical utility was the barrier most strongly associated with less frequent use of MBC. CONCLUSIONS: Although evidence exists for efficacy of MBC in behavioral health care, less than half of BHCPs reported using MBC with at least half of their patients, and low perceived clinical utility of MBC was strongly associated with lower MBC use. Implementation strategies that attempt to change negative attitudes toward MBC may effectively target this barrier to use.

RESUMO

Emergency department (ED) psychiatrists face the consequential decision to pursue involuntary inpatient psychiatric admission. Research on the relationship between patient characteristics and the decision to pursue involuntary psychiatric admission is limited. Using data from 2017 to 2018 at an urban Los Angeles hospital, we used generalized linear mixed effects models to compare patients who were involuntarily admitted to inpatient psychiatry to patients who were discharged from the ED. Of 2,448 patients included in the study, 1,217 (49.7%) were involuntarily admitted to inpatient psychiatry and 1,231 (50.3%) were discharged. After controlling for sociodemographic characteristics, admitted patients were more likely to have been brought in by police, have had an organized suicide plan or recent attempt, physical signs of harm, psychosis, depression or hopelessness, lack social support, have diagnoses of schizophrenia or bipolar disorder, and be administered injectable psychotropic medications. Stimulant use, a diagnosis of anxiety or developmental disorders, and recent medical ED utilization were associated with discharge. Psychiatrists pursued involuntarily psychiatric hospitalization based on factors potentially indicative of dangerousness, leaving patients, particularly those with recent substance use, without immediate access to treatment. Policies should focus on increasing follow up to high quality, voluntary outpatient mental health care.

RESUMO

BACKGROUND: Collaborations between health systems and community-based organizations (CBOs) are increasingly common mechanisms to address the unmet health-related social needs of high-risk populations. However, there is limited evidence on how to develop, manage, and sustain these partnerships, and implementation rarely incorporates perspectives of community social service organizations. To address these gaps, we elicited CBOs' perspectives on service delivery for clients, the impact of the Whole Person Care-Los Angeles (WPC-LA) initiative to integrate health and social care, and their suggestions for improving health system partnerships. METHODS: Using stakeholder engaged principles and a qualitative Rapid Assessment Process, we conducted brief surveys and in-depth semi-structured interviews with 65 key informants from 36 CBOs working with WPC-LA. RESULTS: Major themes identified by CBOs included: 1) the importance of a holistic, client-centered, continuously engaged approach that is reliant on regional partnerships; 2) benefits of WPC-LA expanding capacity and networks; 3) concerns about communication and redundancy hindering WPC-LA; and 4) a need for more equitable partnerships incorporating their approaches. CONCLUSIONS: CBOs value opportunities for integration with health systems, bring critical expertise to these partnerships, and seek to strengthen cross-sector collaborations. Early, equitable, and inclusive participation in the development and implementation of these partnerships may enhance their effectiveness, but requires policy that prioritizes and incentivizes sustainable and mutually beneficial partnerships.

RESUMO

It has been suggested that psychiatric multimorbidity may better characterize severely impaired psychiatric patients than individual severe mental illness (SMI) diagnoses, and that these patients may be better served by centers offering integrated co-located, psychiatric and social services than in conventional clinics providing one-to-one care. We tested the hypothesis that multimorbidity is a critical characteristic of Veterans treated at a co-located multi-service Veteran's Health Administration (VHA) program originally established to treat Veterans living with SMI. Administrative data from the VA Connecticut Health Care System from fiscal year 2012 were used to compare veterans using diverse mental health and social services at the Errera Community Care Center (ECCC), an integrated "one-stop shop" for SMI veterans, and those seen exclusively at standard outpatient mental health clinics. Bivariate and multiple logistic regression analyses were used to compare groups on demographic characteristics, psychiatric and medical diagnoses, service utilization, and psychotropic medication fills. Results: Of the 11,092 veterans included in the study, 2281 (20.6%) had been treated at the ECCC and 8811 (79.4%) had not. Multivariable analysis highlighted the association of treatment in the ECCC and younger age, lower income, homelessness, and especially multimorbidity including both multiple substance use and multiple psychiatric diagnoses. Programs originally designed to address the diverse needs of patients living with SMI and homelessness may be usefully characterized as treating patients with psychiatric multimorbidity, a term of greater clinical relevance. Effectiveness research is needed to evaluate the one-stop shop approach to their treatment.

RESUMO

BACKGROUND: Since deinstitutionalization in the 1950s-1970s, public mental health care has changed its focus from asylums to general hospitals, outpatient clinics and specialized community-based programs addressing both clinical and social determinants of mental health. Analysis of the place of community-based programs within a comprehensive health system such as the Veterans Health Administration (VHA) may illuminate the role of social forces in shaping contemporary public mental health systems. METHODS: National VHA administrative data were used to compare veterans who exclusively received outpatient clinic care to those receiving four types of specialized community-based services, addressing: 1) functional disabilities from severe mental illness (SMI), 2) justice system involvement, 3) homelessness, and 4) vocational rehabilitation. Bivariate comparisons and multinomial logistic regression analyses compared groups on demographics, diagnoses, service use, and psychiatric prescription fills. RESULTS: An hierarchical classification of 1,386,487 Veterans who received specialty mental health services from VHA in Fiscal Year 2012, showed 1,134,977 (81.8%) were seen exclusively in outpatient clinics; 27,931 (2.0%) received intensive SMI-related services; 42,985 (3.1%) criminal justice services; 160,273 (11.6%) specialized homelessness services; and 20,921 (1.5%) vocational services. Compared to those seen only in clinics, veterans in the four community treatment groups were more likely to be black, diagnosed with HIV and hepatitis, had more numerous substance use diagnoses and made far more extensive use of mental health outpatient and inpatient care. CONCLUSIONS: Almost one-fifth of VHA mental health patients receive community-based services prominently addressing major social determinants of health and multimorbid substance use disorders.

RESUMO

Co-morbidity between medical and psychiatric conditions is commonly considered between individual pairs of conditions. However, an important alternative is to consider all conditions as part of a co-morbidity network, which encompasses all interactions between patients and a healthcare system. Analysis of co-morbidity networks could detect and quantify general tendencies not observed by smaller-scale studies. Here, we investigate the co-morbidity network derived from longitudinal healthcare records from approximately 1 million United States military veterans, a population disproportionately impacted by psychiatric morbidity and psychological trauma. Network analyses revealed marked and heterogenous patterns of co-morbidity, including a multi-scale community structure composed of groups of commonly co-morbid conditions. Psychiatric conditions including posttraumatic stress disorder were strong predictors of future medical morbidity. Neurological conditions and conditions associated with chronic pain were particularly highly co-morbid with psychiatric conditions. Across conditions, the degree of co-morbidity was positively associated with mortality. Co-morbidity was modified by biological sex and could be used to predict future diagnostic status, with out-of-sample prediction accuracy of 90-92%. Understanding complex patterns of disease co-morbidity has the potential to lead to improved designs of systems of care and the development of targeted interventions that consider the broader context of mental and physical health.

RESUMO

Patients with psychiatric disorders are treated by both mental health specialists and non-specialists. We use national data from the Veterans Health Administration to evaluate changing proportions of patients seen exclusively by non-specialists during the study year (FY 2012) limit as well as differences in socio-demographic, clinical and service use characteristics. There has been a five-fold increase in veterans with mental disorders seen by non-specialists over 20 years from 7 to 38%, findings similar to those in non-VA settings. Veterans treated by mental health specialists were younger, more likely to have been homeless and disabled, and had more severe and more numerous psychiatric diagnoses. There is a need to maintain specialty services and to strengthen non-specialty care through education and research.

RESUMO

Objective: A distinct group of patients has recently been described who experience polysubstance use disorder characterized by use of multiple addictive substances. This study examines baseline characteristics and longitudinal outcomes of a group of such patients in specialized intensive Veterans Health Administration posttraumatic stress disorder (PTSD) programs and followed 4 months after discharge. Methods: Patients with diagnosed PTSD or subsyndromal PTSD and who used a single substance at baseline were compared to those who used two or three and more than three different addictive substances on measures of PTSD symptom severity and functioning. Comparisons were also adjusted for differences in total days of any substance use and other potentially confounding factors. Patients were reclassified according to the number of substances used at follow-up and again compared on symptoms and functioning. Results: Bivariate analysis of baseline data (N = 8,240) showed frequent polysubstance use (n = 3,695, 44.8% of the sample) and that use of greater numbers of substances was associated with more severe PTSD symptoms as well as more total days of substance use. At follow-up after treatment, 58.2% of the original sample (n = 4,797) was assessed. Polysubstance use was less frequent (n = 756, 15.8% of the follow-up sample), but showed a similar association with more severe symptoms, although differences were attenuated after adjusting for total days of substance use. Conclusions: Polysubstance use, conceptualized within the multimorbidity perspective, is associated with increased severity of PTSD symptoms among veterans with dual diagnoses requiring complex interventions, the evaluation of which will require innovative trial designs.

RESUMO

OBJECTIVE: While "dual diagnosis" involving both psychiatric and substance use disorders has long been a focus of schizophrenia research, recent studies have advocated for a shift of focus to multimorbidity, addressing comorbidity from both additional psychiatric disorders and substance use disorders. We hypothesized that more extensive mental health multimorbity would be associated with poorer quality of life (QOL) and functioning, and that additional psychiatric comorbidity in schizophrenia would have similar adverse effects on QOL as substance use comorbidity. METHODS: Participants with schizophrenia in the NIMH-funded Clinical Antipsychotic Trials of Intervention Effectiveness (CATIE) were classified using baseline diagnostic data into four groups: 1) monomorbid schizophrenia: 2) additional psychiatric comorbidity, 3) additional substance use comorbidity, and 4) both additional psychiatric and substance use comorbidity. Mixed models compared groups on self-reported QOL (SF-12 and Lehman QOLI) and rater-evaluated QOL (the Quality of Life Scale) using baseline, 6, 12 and 18-month follow-up data. RESULTS: As hypothesized, patients with schizophrenia alone had a better QOL than those with any multimorbidity; patients with both psychiatric and substance use comorbidities had a worse QOL than those with fewer comorbidities; and patients with comorbid substance use alone were not significantly worse off than those with comorbid psychiatric disorder. CONCLUSION: The multimorbidity framework more richly differentiates complex clinical presentations of schizophrenia than the current dual diagnosis concept and deserves further study as to its etiology, consequences, and treatment.

RESUMO

OBJECTIVE: There has been increasing interest within psychiatry in the concept of multimorbidity because psychiatric patients typically present with multiple concurrent disorders, these disorders mutually exacerbate one another, and their interaction shapes treatment options. Metrics have not been developed to document multimorbidity in psychiatric clinical practice. METHODS: Four classes of indicators relevant to multimorbidity were defined and evaluated among veterans treated in mental health specialty clinics nationally in the Veterans Health Administration (VHA) in fiscal year 2012. RESULTS: Of the 843,583 veterans with at least three visits to a specialty mental health clinic, 94.6% had more than one general medical or mental disorder and 77.6% had more than one mental disorder, compared with 30.6% with co-occurring psychiatric and substance use disorders. CONCLUSIONS: Real-world psychiatric care is more accurately approached from the multimorbidity perspective than from the perspective of principal, dual, or comorbid diagnoses.

RESUMO

OBJECTIVE: While research on substance abuse has largely focused on people who have a single substance use disorder (SUD), many people abuse multiple substances. Studies have yet to examine the distinctive characteristics of patients diagnosed with more than 1 SUD and how those with polysubstance use disorder (PSUD) differ from those with a single SUD. METHODS: National Veterans Health Administration data from fiscal year 2012 were used to compare veterans diagnosed 1 SUD to veterans diagnosed with 2-3, and >3 SUDs on demographic characteristics, psychiatric and medical diagnoses, medical and psychiatric service utilization, and psychotropic medication fills. Comparisons of the 3 groups were based on bivariate and multiple logistic regression analyses. RESULTS: Of the 472,624 veterans with at least 1 diagnosed SUD, 346,329 (73.2%) had 1 disorder, 113,598 (24.0%) had 2-3, and 12,715 (2.7%) had >3 SUDs. Veterans with higher levels of PSUD were more likely to be black and homeless, were more likely to have hepatic disease as well as schizophrenia, bipolar disorder, major depressive disorder, and personality disorders. Higher levels of PSUD were associated with greater use of psychiatric inpatient care, residential and rehabilitative treatment, and with multiple psychotropic medication prescription fills. CONCLUSIONS: Veterans with PSUD have more severe problems along several dimensions and use more numerous and varied services than those with 1 SUD. This distinctive clinical profile warrants research to develop and evaluate methods for treating patients with complex multimorbid disorders that involve interactions between medical morbidity and psychosocial dysfunction.

RESUMO

Introduction: High-fidelity mannequin-based simulation is frequently used to compliment medical student education during clinical clerkships. However, psychiatric educators have not broadly adopted this modality, focusing rather on standardized patient actors. We developed and delivered a simulation case involving a patient with alcohol withdrawal and lithium toxicity followed by a debriefing session to medical students at the end of their psychiatric clerkship. Methods: The case involves a 40-year-old male truck driver with a history of bipolar disorder who presents to the emergency room after a truck accident. The patient is in alcohol withdrawal, which responds to benzodiazepines. A workup reveals that the patient also has lithium toxicity related to the co-ingestion of lithium and naproxen for pain. Participants learn to evaluate and treat alcohol withdrawal, consider medical comorbidities and legal consequences, and complete a brief intervention for substance use. This case requires a simulation mannequin. Results: To date, 150 second-, third-, and fourth-year medical students have participated in this case and 76 have been surveyed. Participants have provided a postsession rating of 4.49 on a 5-point Likert scale (1 = strongly disagree and 5 = strongly agree) on a question about enjoyment, and 3.93 on a question about confidence with evaluation and treatment of patients in alcohol withdrawal. Discussion: Psychiatric education currently underutilizes mannequin-based simulation compared to other medical disciplines. Mannequin simulation is feasible and effective in psychiatric education, especially in cases involving medical complexity, as shown in this novel case involving a patient with alcohol withdrawal and lithium toxicity.

RESUMO

BACKGROUND: Current attempts at understanding the heterogeneity in obsessive-compulsive disorder have relied on quantitative methods. The results of such work point toward a dimensional structure for obsessive-compulsive disorder. Existing qualitative work in obsessive-compulsive disorder has focused on understanding specific aspects of the obsessive-compulsive disorder experience in greater depth. However, qualitative methods are also of potential value in furthering our understanding of obsessive-compulsive disorder heterogeneity by allowing for open-ended exploration of the obsessive-compulsive disorder experience and correlating identified subtypes with patient narratives. OBJECTIVE: We explored variations in patients' experience prior to, during and immediately after performing their compulsions. METHOD: Semi-structured interviews were conducted with 20 adults with obsessive-compulsive disorder, followed by inductive thematic analysis. Participant responses were not analyzed within the context of an existing theoretical framework, and themes were labeled descriptively. RESULTS: The previous dichotomy of 'anxiety' vs 'incompleteness' emerged organically during narrative analysis. In addition, we found that some individuals with obsessive-compulsive disorder utilized their behaviors as a way to cope with stress and anxiety more generally. Other participants did not share this experience and denied finding any comfort in their obsessive-compulsive behaviors. The consequences of attentional difficulties were highlighted, with some participants describing how difficulty focusing on a task could influence the need for it to be repeated multiple times. CONCLUSIONS: The extent to which patients use obsessive-compulsive disorder as a coping mechanism is a relevant distinction with potential implications for treatment engagement. Patients may experience ambivalence about suppressing behaviors that they have come to rely upon for management of stress and anxiety, even if these behaviors represent symptoms of a psychiatric illness.

RESUMO

PURPOSE: The von Hippel-Lindau (VHL) gene is often inactivated (by mutation or promoter hypermethylation) in renal cell carcinoma but the relation to therapeutic outcome is unclear. MATERIALS AND METHODS: Patients with metastatic clear cell renal cell carcinoma with available baseline tumor samples who received vascular endothelial growth factor targeted therapy were included in analysis. Patient characteristics, VHL gene status and clinical outcome were documented. Our primary end point was to test for response rate in relation to VHL inactivation. Progression-free survival and overall survival in relation to VHL status were investigated as secondary end points. RESULTS: A total of 123 patients were evaluable. Response rate, median progression-free survival and median overall survival were 37% (95% CI 28-46), 10.8 (95% CI 7.7-14.8) and 29.8 (CI not estimable) months, respectively. Patients with VHL inactivation had a response rate of 41% vs 31% for those with wild-type VHL (p = 0.34). Patients with loss of function mutations (frameshift, nonsense, splice and in-frame deletions/insertions) had a 52% response rate vs 31% with wild-type VHL (p = 0.04). On multivariate analysis the presence of a loss of function mutation remained an independent prognostic factor associated with improved response. Progression-free survival and overall survival were not significantly different based on VHL status. CONCLUSIONS: To our knowledge this is the largest analysis investigating the impact of VHL inactivation on the outcome of vascular endothelial growth factor targeted agents in metastatic renal cell carcinoma. We did not find a statistically significant increase in response to vascular endothelial growth factor targeted agents in patients with VHL inactivation. Loss of function mutations identified a population of patients with a greater response. Investigation of downstream markers is under way.
