RESUMO

Our goal was to investigate the sustainability of care practices that are consistent with the collaborative chronic care model (CCM) in nine outpatient mental health teams located within US Department of Veterans Affairs (VA) medical centers, three to four years after the completion of CCM implementation. We conducted qualitative interviews (N = 30) with outpatient mental health staff from each of the nine teams. We based our directed content analysis on the six elements of the CCM. We found variable sustainability of CCM-based care processes across sites. Some care processes, such as delivery of evidence-based psychotherapies (EBPs) and use of measurement-based care (MBC) to guide clinic decision-making, were robustly maintained or even expanded within participating teams. In contrast, other care processes-which had in some cases been developed with considerable effort-had not been sustained. For example, care manager roles were diminished in scope or eliminated completely in response to workload pressures, frontline care needs, or the COVID-19 pandemic. Similarly, processes for engaging Veterans more fully in decision-making had generally been scaled back. Leadership support in the form of adequate team staffing and time to conduct team meetings were seen as crucial for sustaining CCM-consistent care. Given the potential impact of leadership turnover on sustainability in mental health, future efforts to implement CCM-based mental health care should strive to involve multiple leaders in implementation and sustainment efforts, lest one key departure undo years of implementation work. Our results also suggest that implementing CCM processes may best be conceptualized as a partnership across multiple levels of medical center leadership.

RESUMO

BACKGROUND: Increasingly, women are serving in the military and seeking care at the Veterans Health Administration (VHA). Women veterans face unique challenges and barriers in seeking mental health (MH) care within VHA. VA Video Connect (VVC), which facilitates video-based teleconferencing between patients and providers, can reduce barriers while maintaining clinical effectiveness. OBJECTIVE: Primary aims were to examine gender differences in VVC use, describe changes in VVC use over time (including pre-COVID and 6 months following the beginning of COVID), and determine whether changes over time differed by gender. DESIGN: A retrospective cohort investigation of video-to-home telehealth for MH care utilization among veterans having at least 1 MH visit from October 2019 to September 2020. PARTICIPANTS: Veterans (236,268 women; 1,318,024 men). INTERVENTIONS (IF APPLICABLE): VVC involves face-to-face, synchronous, video-based teleconferencing between patients and providers, enabling care at home or another private location. MAIN MEASURES: Percentage of MH encounters delivered via VA Video Connect. KEY RESULTS: Women veterans were more likely than men to have at least 1 VVC encounter and had a greater percentage of MH care delivered via VVC in FY20. There was an increase in the percentage of MH encounters that were VVC over FY20, and this increase was greater for women than men. Women veterans who were younger than 55 (compared to those 55 and older), lived in urban areas (compared to those in rural areas), or were Asian (compared to other races) had a greater percentage of MH encounters that were VVC since the start of the pandemic, controlling for the mean percentage of VVC MH encounters in the 6 months pre-pandemic. CONCLUSIONS: VVC use for MH care is greater in women veterans compared to male veterans and may reduce gender-specific access barriers. Future research and VVC implementation efforts should emphasize maximizing patient choice and satisfaction.

RESUMO

Background: The use of telemental health via videoconferencing (TMH-V) became critical during the Coronavirus disease 2019 (COVID-19) pandemic due to restriction of non-urgent in-person appointments. The current brief report demonstrates the rapid growth in TMH-V appointments in the weeks following the pandemic declaration within the Department of Veterans Affairs (VA), the largest healthcare system in the United States. Methods: COVID-19 changes in TMH-V appointments were captured during the six weeks following the World Health Organization's pandemic declaration (March 11, 2020-April 22, 2020). Pre-COVID-19 TMH-V encounters were assessed from October 1, 2017 to March 10, 2020. Results: Daily TMH-V encounters rose from 1,739 on March 11 to 11,406 on April 22 (556% growth, 222,349 total encounters). Between March 11-April 22, 114,714 patients were seen via TMH-V, and 77.5% were first-time TMH-V users. 12,342 MH providers completed a TMH-V appointment between March 11-April 22, and 34.7% were first-time TMH-V users. The percentage growth of TMH-V appointments was higher than the rise in telephone appointments (442% growth); in-person appointments dropped by 81% during this time period. Discussion and Conclusions: The speed of VA's growth in TMH-V appointments in the wake of the COVID-19 pandemic was facilitated by its pre-existing telehealth infrastructure, including earlier national efforts to increase the number of providers using TMH-V. Longstanding barriers to TMH-V implementation were lessened in the context of a pandemic, during which non-urgent in-person MH care was drastically reduced. Future work is necessary to understand the extent to which COVID-19 related changes in TMH-V use may permanently impact mental health care provision.

RESUMO

ABSTRACT: Effective teaching methods are critical to the acquisition of physical assessment skills. This article describes the combined use of deliberate practice, standardized patient simulation, and peer evaluation in improving physical assessment skills among first-semester nursing students. Students prepared for a physical assessment check-off by using deliberate practice throughout the semester; they then received peer feedback after a standardized patient simulation. Students felt the integrated experience improved their physical assessment performance. Incorporating this innovative educational trio can provide opportunities for physical assessment skill enhancement.

RESUMO

BACKGROUND: Extensive evidence indicates that Collaborative Chronic Care Models (CCMs) improve outcome in chronic medical conditions and depression treated in primary care. Beginning with an evidence synthesis which indicated that CCMs are also effective for multiple mental health conditions, we describe a multistage process that translated this knowledge into evidence-based health system change in the US Department of Veterans Affairs (VA). EVIDENCE SYNTHESIS: In 2010, recognizing that there had been numerous CCM trials for a wide variety of mental health conditions, we conducted an evidence synthesis compiling randomized controlled trials of CCMs for any mental health condition. The systematic review demonstrated CCM effectiveness across mental health conditions and treatment venues. Cumulative meta-analysis and meta-regression further informed our approach to subsequent CCM implementation. POLICY IMPACT: In 2015, based on the evidence synthesis, VA Office of Mental Health and Suicide Prevention (OMHSP) adopted the CCM as the model for their outpatient mental health teams. RANDOMIZED IMPLEMENTATION TRIAL: In 2015-2018 we partnered with OMHSP to conduct a 9-site stepped wedge implementation trial, guided by insights from the evidence synthesis. SCALE-UP AND SPREAD: In 2017 OMHSP launched an effort to scale-up and spread the CCM to additional VA medical centers. Seventeen facilitators were trained and 28 facilities engaged in facilitation. DISCUSSION: Evidence synthesis provided leverage for evidence-based policy change. This formed the foundation for a health care leadership/researcher partnership, which conducted an implementation trial and subsequent scale-up and spread effort to enhance adoption of the CCM, as informed by the evidence synthesis.

RESUMO

Free clinics increase access to care, however, patients frequently miss appointments. The purpose of this quality improvement project was to determine if providing patient navigation affects first appointment no-show rates and hemoglobin A1c (HbA1c) in uninsured patients with diabetes at a free clinic. For 6 months, all patients scheduled for new appointments received weekly patient navigation calls. First appointment no-show rates decreased by 17.7% (p = 0.01). Among patients who received at least one patient navigation call, a significantly greater proportion attended their first appointment (72%) compared to the show rate for those who did not receive a completed call (43%) (p = 0.004).

RESUMO

Reliable first-principles calculations of electrochemical processes require accurate prediction of the interfacial capacitance, a challenge for current computationally efficient continuum solvation methodologies. We develop a model for the double layer of a metallic electrode that reproduces the features of the experimental capacitance of Ag(100) in a non-adsorbing, aqueous electrolyte, including a broad hump in the capacitance near the potential of zero charge and a dip in the capacitance under conditions of low ionic strength. Using this model, we identify the necessary characteristics of a solvation model suitable for first-principles electrochemistry of metal surfaces in non-adsorbing, aqueous electrolytes: dielectric and ionic nonlinearity, and a dielectric-only region at the interface. The dielectric nonlinearity, caused by the saturation of dipole rotational response in water, creates the capacitance hump, while ionic nonlinearity, caused by the compactness of the diffuse layer, generates the capacitance dip seen at low ionic strength. We show that none of the previously developed solvation models simultaneously meet all these criteria. We design the nonlinear electrochemical soft-sphere solvation model which both captures the capacitance features observed experimentally and serves as a general-purpose continuum solvation model.

RESUMO

A major goal of energy research is to use visible light to cleave water directly, without an applied voltage, into hydrogen and oxygen. Although SrTiO3 requires ultraviolet light, after four decades, it is still the "gold standard" for the photo-catalytic splitting of water. It is chemically robust and can carry out both hydrogen and oxygen evolution reactions without an applied bias. While ultrahigh vacuum surface science techniques have provided useful insights, we still know relatively little about the structure of these electrodes in contact with electrolytes under operating conditions. Here, we report the surface structure evolution of a n-SrTiO3 electrode during water splitting, before and after "training" with an applied positive bias. Operando high-energy X-ray reflectivity measurements demonstrate that training the electrode irreversibly reorders the surface. Scanning electrochemical microscopy at open circuit correlates this training with a 3-fold increase of the activity toward the photo-induced water splitting. A novel first-principles joint density functional theory simulation, constrained to the X-ray data via a generalized penalty function, identifies an anatase-like structure as the more active, trained surface.

RESUMO

Continuum solvation models enable electronic structure calculations of systems in liquid environments, but because of the large number of empirical parameters, they are limited to the class of systems in their fit set (typically organic molecules). Here, we derive a solvation model with no empirical parameters for the dielectric response by taking the linear response limit of a classical density functional for molecular liquids. This model directly incorporates the nonlocal dielectric response of the liquid using an angular momentum expansion, and with a single fit parameter for dispersion contributions it predicts solvation energies of neutral molecules with a RMS error of 1.3 kcal/mol in water and 0.8 kcal/mol in chloroform and carbon tetrachloride. We show that this model is more accurate for strongly polar and charged systems than previous solvation models because of the parameter-free electric response, and demonstrate its suitability for ab initio solvation, including self-consistent solvation in quantum Monte Carlo calculations.

RESUMO

Classical density-functional theory is the most direct approach to equilibrium structures and free energies of inhomogeneous liquids, but requires the construction of an approximate free-energy functional for each liquid of interest. We present a general recipe for constructing functionals for small-molecular liquids based only on bulk experimental properties and ab initio calculations of a single solvent molecule. This recipe combines the exact free energy of the non-interacting system with fundamental measure theory for the repulsive contribution and a weighted density functional for the short-ranged attractive interactions. We add to these ingredients a weighted polarization functional for the long-range correlations in both the rotational and molecular-polarizability contributions to the dielectric response. We also perform molecular dynamics calculations for the free energy of cavity formation and the high-field dielectric response, and show that our free-energy functional adequately describes these properties (which are key for accurate solvation calculations) for all three solvents in our study: water, chloroform, and carbon tetrachloride.

RESUMO

Solid-liquid interfaces are at the heart of many modern-day technologies and provide a challenge to many materials simulation methods. A realistic first-principles computational study of such systems entails the inclusion of solvent effects. In this work, we implement an implicit solvation model that has a firm theoretical foundation into the widely used density-functional code Vienna ab initio Software Package. The implicit solvation model follows the framework of joint density functional theory. We describe the framework, our algorithm and implementation, and benchmarks for small molecular systems. We apply the solvation model to study the surface energies of different facets of semiconducting and metallic nanocrystals and the SN2 reaction pathway. We find that solvation reduces the surface energies of the nanocrystals, especially for the semiconducting ones and increases the energy barrier of the SN2 reaction.

RESUMO

The demand for palliative and end-of-life nursing is increasing with the aging US population. The American Association of Colleges of Nursing published recommendations for incorporating palliative and end-of-life care across nursing curriculum to prepare the future workforce. However, recommendations regarding teaching end-of-life content are limited. This project aimed to integrate and evaluate the outcomes of end-of-life education introduced in a prelicensure nursing program. Using a documentary created by the American Nurses Foundation, students had the opportunity to discuss common themes in end-of-life care, practice morgue care in the simulation laboratory, and practice reflective journaling. The students' preevaluations and postevaluations indicated that the educational program significantly increased their confidence in providing end-of-life care and support to patients and families, demonstrating the importance of end-of-life curricula in nursing school.

RESUMO

BACKGROUND: Sustaining evidence-based practices (EBPs) is crucial to ensuring care quality and addressing health disparities. Approaches to identifying factors related to sustainability are critically needed. One such approach is Matrixed Multiple Case Study (MMCS), which identifies factors and their combinations that influence implementation. We applied MMCS to identify factors related to the sustainability of the evidence-based Collaborative Chronic Care Model (CCM) at nine Department of Veterans Affairs (VA) outpatient mental health clinics, 3-4 years after implementation support had concluded. METHODS: We conducted a directed content analysis of 30 provider interviews, using 6 CCM elements and 4 Integrated Promoting Action on Research Implementation in Health Services (i-PARIHS) domains as codes. Based on CCM code summaries, we designated each site as high/medium/low sustainability. We used i-PARIHS code summaries to identify relevant factors for each site, the extent of their presence, and the type of influence they had on sustainability (enabling/neutral/hindering/unclear). We organized these data into a sortable matrix and assessed sustainability-related cross-site trends. RESULTS: CCM sustainability status was distributed among the sites, with three sites each being high, medium, and low. Twenty-five factors were identified from the i-PARIHS code summaries, of which 3 exhibited strong trends by sustainability status (relevant i-PARIHS domain in square brackets): "Collaborativeness/Teamwork [Recipients]," "Staff/Leadership turnover [Recipients]," and "Having a consistent/strong internal facilitator [Facilitation]" during and after active implementation. At most high-sustainability sites only, (i) "Having a knowledgeable/helpful external facilitator [Facilitation]" was variably present and enabled sustainability when present, while (ii) "Clarity about what CCM comprises [Innovation]," "Interdisciplinary coordination [Recipients]," and "Adequate clinic space for CCM team members [Context]" were somewhat or less present with mixed influences on sustainability. CONCLUSIONS: MMCS revealed that CCM sustainability in VA outpatient mental health clinics may be related most strongly to provider collaboration, knowledge retention during staff/leadership transitions, and availability of skilled internal facilitators. These findings have informed a subsequent CCM implementation trial that prospectively examines whether enhancing the above-mentioned factors within implementation facilitation improves sustainability. MMCS is a systematic approach to multi-site examination that can be used to investigate sustainability-related factors applicable to other EBPs and across multiple contexts.

RESUMO

Background: Sustaining healthcare interventions once they have been implemented is a pivotal public health endeavor. Achieving sustainability requires context-sensitive adaptations to evidence-based practices (EBPs) or the implementation strategies used to ensure their adoption. For replicability of adaptations beyond the specific setting in question, the underlying logic needs to be clearly described, and adaptations themselves need to be plainly documented. The goal of this project was to describe the process by which implementation facilitation was adapted to improve the uptake of clinical care practices that are consistent with the collaborative chronic care model (CCM). Method: Quantitative and qualitative data from a prior implementation trial found that CCM-consistent care practices were not fully sustained within outpatient general mental health teams that had received 1 year of implementation facilitation to support uptake. We undertook a multistep consensus process to identify adaptations to implementation facilitation based on these results, with the goal of enhancing the sustainability of CCM-based care in a subsequent trial. The logic for these adaptations, and the resulting adaptations themselves, were documented using two adaptation-oriented implementation frameworks (the iterative decision-making for evaluation of adaptations [IDEA] and the framework for reporting adaptations and modifications to evidence-based implementation strategies [FRAME-IS], respectively). Results: Three adaptations emerged from this process and were documented using the FRAME-IS: (a) increasing the scope of implementation facilitation within the medical center, (b) having the internal facilitator take a greater role in the implementation process, and (c) shortening the implementation timeframe from 12 to 8 months, while increasing the intensity of facilitation support during that time. Conclusions: EBP sustainability may require careful adaptation of EBPs or the implementation strategies used to get them into routine practice. Recently developed frameworks such as the IDEA and FRAME-IS may be used to guide decision-making and document resulting adaptations themselves. An ongoing funded study is investigating the utility of the resulting adaptations for improving healthcare.


Evidence-based treatments may not be sustained after they have been implemented in healthcare settings. To address this, treatments and implementation strategies may need to be adapted to fit the local context or the patient population. Maximizing the usefulness of such adaptations requires documenting the decision-making process. Understanding how an implementation strategy has been adapted for a given study or setting is crucial to ensuring that adaptations don't compromise fidelity to the implementation strategy while enabling its replicability in similar settings. This article uses two adaptation frameworks to describe the process by which implementation facilitation, a common implementation strategy, was adapted to help establish and sustain effective mental health clinical teams in VA medical centers. It is our hope that our description of this process may help healthcare researchers, administrators, and policymakers to describe and document adaptations to implementation strategies in their own settings.

RESUMO

Video telehealth experienced rapid growth throughout the COVID-19 pandemic in many healthcare sectors, including mental health. The Veterans Health Administration's video telehealth platform, VA Video Connect, has been widely used to reach veterans who may have experienced difficulty accessing care, such as those living in rural areas or other barriers (e.g., transportation). Implementing VVC requires a multifaceted approach, including training providers on technical skills, increasing access to equipment for providers and veterans, and integrating VVC within the culture and processes of the clinic unit. Prior successful VVC implementation efforts in rural areas have focused on simultaneous one-on-one provider and leadership engagement using implementation facilitation (IF). However, given the rapid need for VVC expansion in light of limits and dangers associated with in-person care during the pandemic, our team developed group facilitation to increase the reach of VVC implementation through IF. Group facilitation combined training in technical and policy elements of VVC with IF with groups of providers from clinic units. This approach was designed to rapidly disseminate the necessary knowledge to conduct VVC combined with collaborative problem solving as a team to improve the ability of the clinical team to sustain VVC. Attendees were asked for feedback on the session through multiple choice and open-ended questions. Participants (N = 26) reported being highly satisfied with the training and reported a high degree of confidence in their ability to use VVC. Based on evaluation data and interview feedback, providers and clinic leaders were satisfied with group facilitation. Group facilitation may be a helpful tool in rapidly training clinical teams to implement and sustain video telemental health.

RESUMO

BACKGROUND: The evidence-based Collaborative Chronic Care Model (CCM), developed to help structure care for chronic health conditions, comprises six elements: work role redesign, patient self-management support, provider decision support, clinical information systems, linkages to community resources, and organizational/leadership support. As the CCM is increasingly implemented in real-world settings, there is heightened interest in understanding specific influences upon implementation. Therefore, guided by the Integrated Promoting Action on Research Implementation in Health Services (i-PARIHS) framework, we (i) identified innovation-, recipient-, context-, and facilitation-related influences on CCM implementation and (ii) assessed the influences' relationship to each CCM element's implementation. METHODS: Using semi-structured interviews, we examined interdisciplinary behavioral health providers' experiences at nine VA medical centers that implemented the CCM. We used i-PARIHS constructs as a priori codes for directed content analysis, then analyzed the data for cross-coding by CCM element and i-PARIHS construct. RESULTS: Participants (31 providers) perceived the CCM innovation as enabling comprehensive care but challenging to coordinate with existing structures/procedures. As recipients, participants recounted not always having the authority to design CCM-consistent care processes. They perceived local leadership support to be indispensable to implementation success and difficult to garner when CCM implementation distracted from other organizational priorities. They found implementation facilitation helpful for keeping implementation on track. We identified key themes at the intersection of i-PARIHS constructs and core CCM elements, including (i) the CCM being an innovation that offers a formal structure to stepping down care intensity for patients to encourage their self-management, (ii) recipients accessing their multidisciplinary colleagues' expertise for provider decision support, (iii) relationships with external services in the community (e.g., homelessness programs) being a helpful context for providing comprehensive care, and (iv) facilitators helping to redesign specific interdisciplinary team member roles. CONCLUSIONS: Future CCM implementation would benefit from (i) facilitating strategic development of supportive maintenance plans for patients' self-management, (ii) collocating multidisciplinary staff (on-site or virtually) to enhance provider decision support, (iii) keeping information on available community resources up to date, and (iv) making clearer the explicit CCM-consistent care processes that work roles can be designed around. This work can inform concrete tailoring of implementation efforts to focus on the more challenging CCM elements, which is crucial to better account for multiple influences that vary across diverse care settings in which the CCM is being implemented.

RESUMO

We present an accurate equation of state for water based on a simple microscopic Hamiltonian, with only four parameters that are well-constrained by bulk experimental data. With one additional parameter for the range of interaction, this model yields a computationally efficient free-energy functional for inhomogeneous water, which captures short-ranged correlations, cavitation energies, and, with suitable long-range corrections, the nonlinear dielectric response of water, making it an excellent candidate for the studies of mesoscale water and for use in ab initio solvation methods.

RESUMO

BACKGROUND: The coronavirus disease 2019 (COVID-19) pandemic dramatically increased the use of telemental health via videoconferencing (TMH-V). While TMH-V has been found to be effective and satisfactory to both patients and providers, little is known regarding factors that influence site-level uptake. We examined facilitators and barriers to TMH-V uptake at higher and lower adoption sites within the US Department of Veterans Affairs (VA). METHODS: We conducted twenty-four semi-structured qualitative interviews at four northeastern VA medical centers (two with higher TMH-V adoption and two with lower adoption). Six interviews were conducted per site (one member of mental health leadership, one facility telehealth coordinator/technician, and four mental health providers per site). We performed directed content analysis, guided by the Consolidated Framework for Implementation Research (CFIR), followed by a matrix rating process to rank the degree of influence of each of the 19 included CFIR constructs at the four sites. Positive overall influences, negative overall influences, and differentiators were then identified based on patterns in ratings across sites. RESULTS: Five CFIR constructs had positive overall influences across sites: Relative advantage, Patient needs and resources, Relative priority, Knowledge and beliefs, and Self-efficacy. Complexity had a negative overall influence across sites. Four constructs significantly differentiated between higher and lower adoption sites with regards to TMH-V use: Quality, Compatibility, Leadership engagement, and Champions. CONCLUSIONS: Several positive overall influences on TMH-V uptake were identified across sites; respondents acknowledged multiple advantages of TMH-V (e.g., convenience), and providers' attitudes towards TMH-V improved as they gained experience. In contrast, complexity was a negative overall influence; TMH-V platforms and processes must be simple and user friendly to promote use. The emergence of Quality, Leadership engagement, and Champions as differentiators speaks to the importance of educating frontline staff and leadership at lower adoption sites about the evidence base demonstrating that TMH-V is high-quality care. Compatibility also emerged as a differentiator; if TMH-V is not easily integrated into provider workflows, uptake will falter. Future work should draw from these findings to develop implementation strategies aiming to increase TMH-V uptake at lower adoption sites, thereby increasing access to high-quality mental health care.

RESUMO

The coronavirus disease (COVID-19) pandemic significantly accelerated the growth of telehealth services within the Veterans Health Administration (VHA), as the use of video conferencing to meet with Veterans in their homes increased tenfold in a 3-month period. A substantial portion of telehealth in VHA has traditionally comprised mental health services, and both the scope and volume of such services were significantly broadened in response to COVID-19 to allow for social distancing. The current article is a review of this mobilization from the framework of the People, Process, Technology, and Information model, with a particular highlight on the critical operational partnership between individual facilities providing care and the governing VHA program offices. Lessons learned and future goals for the sustainment and integration of telemental health services are also discussed. (PsycInfo Database Record (c) 2022 APA, all rights reserved).

RESUMO

The current study examined patient and provider differences in use of phone, video, and in-person mental health (MH) services. Participants included patients who completed ≥ 1 MH appointment within the Department of Veterans Affairs (VA) from 10/1/17-7/10/20 and providers who completed ≥ 100 VA MH appointments from 10/1/17-7/10/20. Adjusted odds ratios (aORs) are reported of patients and providers: (a) completing ≥1 video MH appointment in the pre-COVID (10/1/17-3/10/20) and COVID (3/11/20-7/10/20) periods; and (b) completing the majority of MH visits via phone, video, or in-person during COVID. The sample included 2,480,119 patients/31,971 providers in the pre-COVID period, and 1,054,670 patients/23,712 providers in the COVID period. During the pre-COVID and COVID periods, older patients had lower odds of completing ≥ 1 video visit (aORs < .65). During the COVID period, older age and low socioeconomic status predicted lower odds of having ≥ 50% of visits via video versus in-person or phone (aORs < .68); schizophrenia and MH hospitalization history predicted lower odds of having ≥ 50% of visits via video or phone versus in-person (aORs < . 64). During the pre-COVID and COVID periods, nonpsychologists (e.g., psychiatrists) had lower odds of completing video visits (aORs < . 44). Older providers had lower odds of completing ≥ 50% of visits via video during COVID (aORs <. 69). Findings demonstrate a digital divide, such that older and lower income patients, and older providers, engaged in less video care. Nonpsychologists also had lower video use. Barriers to use must be identified and strategies must be implemented to ensure equitable access to video MH services. (PsycInfo Database Record (c) 2022 APA, all rights reserved).
