ABSTRACT

Veterans Health Administration (VHA) continues to expand the mental health (MH) workforce to meet increasing demand for services. In the present study, longitudinal unbiased recursive partitioning models (conditional inference trees) were created to identify optimal cutoffs for outpatient staffing ratios associated with success on VHA's measures of quality, access, and satisfaction. Quarterly Staff-to-Patient Ratios (SPRs), defined as the number of full-time equivalent providers per 1,000 veterans receiving outpatient mental health care, were calculated for 12 quarters from fiscal years 2016-2018. Associations between VHA metrics associated with quality, access, and satisfaction were evaluated in relation to the overall outpatient SPR. The root node identified an overall outpatient SPR of 7.39 as the split for optimal MH performance. Root nodes associated with metrics addressing population coverage, continuity of care, and experience of care identified SPRs of 7.87, 6.81, and 7.42, respectively. In all analyses, the lowest SPRs were associated with the lowest performance on VHA MH metrics, while the highest SPRs were associated with the highest performance. Analyses support VHA's current recommended minimum outpatient SPR of 7.72 as a reasonable target to provide high-quality care, access, and satisfaction.

ABSTRACT

BACKGROUND: Healthcare systems monitor and improve mental health treatment quality, access, continuity and satisfaction through use of population-based and efficiency-based staffing models, the former focused on staffing ratios and the latter, staff productivity. Preliminary evidence suggests that both high staffing ratios and moderate-to-high staff productivity are important for ensuring a full continuum of mental health services to indicated populations. METHODS & FINDINGS: With an information-theoretic approach, we conducted a longitudinal investigation of mental health staffing, productivity and treatment at the largest integrated healthcare system in American, the Veterans Health Administration (VHA). VHA facilities (N = 140) served as the unit of measure, with mental health treatment quality, access, continuity and satisfaction predicted by facility staffing and productivity in longitudinal mixed models. An information-theoretic approach: (a) entails the development of a comprehensive set of plausible models that are fit, ranked and weighted to quantitatively assess the relative support for each, and (b) accounts for model uncertainty while identifying best-fit model(s) that include important and exclude unimportant explanatory variables. In best-fit models, higher staffing was the strongest and most consistent predictor of better treatment quality, access, continuity and satisfaction. Higher staff productivity was often, but not always associated with better treatment quality, access, continuity and satisfaction. Results were further nuanced by differential prediction of treatment by between- and within-facility predictor effects and variable interactions. CONCLUSIONS: A population-based mental health staffing ratio and an efficiency-based productivity value are important longitudinal predictors of mental health treatment quality, access, continuity and satisfaction. Our longitudinal design and use of mixed regression models and an information-theoretic approach addresses multiple limitations of prior studies and strengthen our results. Results are discussed in terms of the provision of mental health treatment by healthcare systems, and analytical modeling of treatment quality, access, continuity and satisfaction.

ABSTRACT

The coronavirus disease 2019 (COVID-19) pandemic has increased the need for psychological care in the global population and has created new barriers to accessing services. Hospitals, mental health facilities, and other clinics face the challenge of providing continued care to a population that is under severe stress, while minimizing in-person visits that risk spreading the virus. The Veterans Health Administration (VHA) is the largest integrated health care system in the United States, providing care at 1,286 sites. VHA ensured the continuity of mental health services after the COVID-19 outbreak by rapidly expanding its use of telemental health methods in the first weeks after the U.S. pandemic outbreak. VHA provided nearly 1.2 million telephone and video encounters to veterans in April 2020 and reduced in-person visits by approximately 80% when compared with the October 2019 to February 2020 period before the pandemic. By June 2020, VHA had an 11-fold increase in encounters using direct-to-home video and a fivefold increase in telephone contacts relative to before the pandemic. This article discusses research on the effectiveness of telemental health, VHA policies before COVID-19 that facilitated the use of telemental health systemwide, and VHA's actions that rapidly scaled use of telemental health during the first months of the outbreak. Key challenges and lessons learned from VHA's experience and implications for providers and health care systems regarding the use of telemental health to meet patients' mental health care needs during the pandemic are also discussed.

ABSTRACT

OBJECTIVE: Mental health treatment access and quality are influenced by the interplay of structural, organizational, and performance factors-including the number of mental health staff providing direct clinical care relative to patients treated (i.e., staffing ratio), mental health staff productivity, and wait times for scheduled mental health appointments. With no industry standards to follow, the Veterans Health Administration (VHA) developed an outpatient mental health staffing model and a recommended minimum total staffing ratio. METHODS: At the level of VHA health care facility (N=140), we conducted cross-sectional regression analyses to examine the relative importance of outpatient mental health staffing and productivity and mental health patient wait times in predicting measures of mental health treatment access and quality. RESULTS: Outpatient mental health staffing ratios (especially total and therapist staffing ratios) had substantial, positive relationships with overall mental health treatment access and quality, broadly and in specific domains. Staffing ratios generally had stronger relationships with treatment access and quality than did staff productivity and patient wait times. CONCLUSIONS: Mental health staffing ratios should be a primary consideration when trying to improve mental health treatment access and quality at the facility level. Having more mental health staff of all types is associated with better overall access to and quality of mental health services, and multiple staff types are needed to provide high-quality mental health care. Knowledge gained may guide efforts to address challenges in improving access to and quality of mental health services within and outside of VHA.

ABSTRACT

With the expansion of integrated primary care and the increased focus on fiscal sustainability, it is critical for clinical managers of these innovative systems to have practical methods for measuring administrative outcomes. Administrative outcomes will assist leadership in the development of efficient, streamlined clinics to provide services to the primary care population. Additionally, administrative measures can be utilized to provide information to assist in guiding resource utilization and management decisions. Several administrative outcomes are suggested for integrated primary care managers to consider for application, including: clinic utilization measures, integrated care administrative measures, wait time and access metrics, and productivity monitors. Effective utilization of these measures can help office managers and clinic leadership not only to maximize patient care, but also to enhance essential business operations, which increase the long-term sustainability of integrated primary care programs.

ABSTRACT

Neuregulin 1 (Nrg1) is a susceptibility gene of schizophrenia, a disabling mental illness that affects 1% of the general population. Here, we show that ctoNrg1 mice, which mimic high levels of NRG1 observed in forebrain regions of schizophrenic patients, exhibit behavioral deficits and hypofunction of glutamatergic and GABAergic pathways. Intriguingly, these deficits were diminished when NRG1 expression returned to normal in adult mice, suggesting that damage which occurred during development is recoverable. Conversely, increase of NRG1 in adulthood was sufficient to cause glutamatergic impairment and behavioral deficits. We found that the glutamatergic impairment by NRG1 overexpression required LIM domain kinase 1 (LIMK1), which was activated in mutant mice, identifying a pathological mechanism. These observations demonstrate that synaptic dysfunction and behavioral deficits in ctoNrg1 mice require continuous NRG1 abnormality in adulthood, suggesting that relevant schizophrenia may benefit from therapeutic intervention to restore NRG1 signaling.

ABSTRACT

Dimensional structures underlying the Wechsler Memory Scale-Fourth Edition (WMS-IV) and Wechsler Memory Scale-Third Edition (WMS-III) were compared to determine whether the revised measure has a more coherent and clinically relevant factor structure. Principal component analyses were conducted in normative samples reported in the respective technical manuals. Empirically supported procedures guided retention of dimensions. An invariant two-dimensional WMS-IV structure reflecting constructs of auditory learning/memory and visual attention/memory (C1 = .97; C2 = .96) is more theoretically coherent than the replicable, heterogeneous WMS-III dimension (C1 = .97). This research suggests that the WMS-IV may have greater utility in identifying lateralized memory dysfunction.

ABSTRACT

Biological relevance is generally the major justification for using nonhuman primates (NHP) during preclinical safety assessment. This holds particularly true for the evaluation of biopharmaceuticals with NHP often being the species of choice. For safety assessment of small molecules, NHP are used in case of a higher degree of metabolic similarity, to detect the highly specific immunotoxic side effects and to discriminate toxicity from efficacy of immunomodulatory drugs. Unlike for rodent immunotoxicity studies, standardized tests and protocols are generally less available for NHP. The immunotoxicity testing protocols described in the present chapter have been adapted for application to NHP samples. In principle, rodent protocols can be transferred to NHP. Fortunately, most of the immunotoxicity parameters delineated in the ICH S8 guideline can be applied to NHP specimens. Exceptions are the host resistance assay and the delayed type hypersensitivity test. Owing to the close structural and physiological similarity between NHP and human, human test kits or reagents are often well suited for application to NHP samples. For data evaluation it should be noted that no inbred strains of NHP are available, resulting in a large inter-animal variability for most immunotoxicity assay results. The experimental protocols and reagents described in this chapter were developed specifically for the cynomolgus monkey (Macaca fascicularis), currently the most commonly used NHP species in toxicology. In many instances, these protocols will also be applicable to rhesus monkeys (M. mulatta) and potentially to other Old World macaques. For the marmoset (Callithrix jacchus), a New World monkey also used in toxicology, the choice of available immunotoxicity testing protocols is much reduced when compared to macaques.

ABSTRACT

HIV is associated with increased risk for depression. Normal appearing white matter (NAWM) fractional anisotropy in 15 HIV-seropositive (HIV+) adults with depressive symptoms was compared to 15 HIV+ adults without depressive symptoms. HIV+ adults with depressive symptoms showed increased NAWM fractional anisotropy within the left thalamus, the temporal, and frontal regions, as well as the right cingulate. Discrete components of depression were associated with distinct regional NAWM fractional anisotropy increases. These results demonstrate altered neural complexity in HIV+ adults with depressive symptoms and support the notion that depression is multifactorial with different morphological alterations contributing to discrete aspects of depression.

ABSTRACT

OBJECTIVE: There are conflicting reports of adverse HIV-associated alterations in white matter integrity as measured by diffusion tensor imaging (DTI). We sought to address these conflicting reports by assessing, on a voxel-by-voxel basis, HIV-associated regional changes in radiologically defined normal-appearing white matter (NAWM) integrity using high-resolution DTI. METHODS: 30 HIV-seropositive (SP) and 30 HIV-seronegative (SN) nondemented, community-dwelling participants underwent DTI to derive whole-brain measures of white matter integrity (fractional anisotropy [FA] and mean diffusivity [MD]). For each participant, the white matter T2 volume was thresholded to remove regions of abnormal signal, resulting in a NAWM mask, which was then applied to the FA and MD volumes to extract voxel-wise NAWM measures of white matter integrity. Voxel-wise group comparisons of FA and MD were conducted (P < 0.005, extent threshold 5 voxels) while controlling for age and substance-abuse history. RESULTS: There were no significant differences between the groups for demographic or cognitive performance variables. Summary whole-brain measures of FA and MD were equivalent between the SP and SN samples. Among the SP sample, history of substance abuse was associated with significantly increased whole-brain NAWM MD, and coinfection with hepatitis C virus (HCV) was associated with a trend for increased MD. Correlations between whole-brain NAWM FA and MD with cognitive performance measures were not significant. Regional analyses of DTI measures revealed variable differences in NAWM FA in the SP sample, with findings of both decreased and increased FA. Differences in NAWM MD were more consistent, with widespread increases noted in the SP sample compared to the SN sample. Eight of the 10 regions displaying significantly increased FA in the SP sample were also found to have significantly increased MD compared to the SN sample. CONCLUSIONS: Decreased white matter integrity is present even in radiologically defined NAWM in nondemented, community-dwelling patients with HIV. The decrease in NAWM integrity is best seen in increases in MD, a measure of generalized tissue breakdown. Indications of NAWM axonal integrity (FA) present a more complicated picture, with both decreased FA and increased FA in the SP sample. Our findings of variable HIV-associated FA changes in NAWM may account for previous conflicting reports of changes in DTI parameters in this population. The results of our study suggest that HIV infection contributes to variable changes in DTI values, reflecting both direct loss of axonal integrity and a loss of complexity to the underlying axonal matrix.

ABSTRACT

A number of recent studies have supported the use of the MMPI-2 Fake Bad Scale (FBS) as a measure of negative response bias, the scale at times demonstrating greater sensitivity to negative response bias than other MMPI-2 validity scales. However, clinicians may not always have access to True FBS (T-FBS) scores, such as when True-False answer sheets are unavailable or published research studies do not report FBS raw scores. Under these conditions, Larrabee (2003a) suggests a linear regression formula that provides estimated FBS (E-FBS) scores derived from weighted validity and clinical T-Scores. The present study intended to validate this regression formula of MMPI-2 E-FBS scores and demonstrate its specificity in a sample of non-litigating, clinically referred, medically intractable epilepsy patients. We predicted that the E-FBS scores would correlate highly (>.70) with the T-FBS scores, that the E-FBS would show comparable correlations with MMPI-2 validity and clinical scales relative to the T-FBS, and that the E-FBS would show an adequate ability to match T-FBS scores using a variety of previously suggested T-FBS raw score cutoffs. Overall, E-FBS scores correlated very highly with T-FBS scores (r = .78, p < .0001), though correlations were especially high for women (r = .85, p < .0001) compared to men (r = .62, p < .001). Thirty-one of 32 (96.9%) comparisons made between E-FBS/T-FBS correlates with other MMPI-2 scales were nonsignificant. When matching to T-FBS "high" and "low" scores, the E-FBS scores demonstrated the highest hit rate (92.5%) through use of Lees-Haley's (1992) revised cutoffs for men and women. These same cutoffs resulted in excellent overall specificity for both the T-FBS scores (92.5%) and E-FBS scores (90.6%). The authors conclude that the E-FBS represents an adequate estimate of T-FBS scores in the current epilepsy sample. Use of E-FBS scores may be especially useful when clinicians conduct the MMPI-2 short form, which does not include all of the 43 FBS items but does include enough items to compute each of the validity and clinical T-Scores. Future studies should examine E-FBS sensitivity in compensation-seekers with incomplete effort.

ABSTRACT

We examined the pattern of neuropsychological deficits in Vascular Cognitive Impairment-No Dementia (Vascular CIND) by comparing the cognitive and behavioral performance of 41 post-stroke Vascular CIND patients to that of 62 post-stroke patients with no cognitive impairment (NCI). Neuropsychological test scores were grouped into seven cognitive and four behavioral domains, then converted to standardized, weighted principle component scores (PCS) for each domain. Multivariate logistic regression models built on cognitive domains found the immediate recall and psychomotor domains to best predict diagnostic group membership. In a separate model limited to behavioral data, the depressed mood domain best predicted group membership. The combination of immediate memory deficits, psychomotor slowness and depression have also been found in Vascular Dementia (VaD), suggesting that the pattern of deficits in Vascular CIND and VaD neuropsychological deficits are similar. This cognitive and behavioral pattern similarity supports the hypothesis that Vascular CIND lies on a continuum between NCI and VaD.
