RESUMO

BACKGROUND: The Veterans Health Administration provides care to more than 100,000 Veterans with cirrhosis. AIMS: This implementation evaluation aimed to understand organizational resources and barriers associated with cirrhosis care. METHODS: Clinicians across 145 Department of Veterans Affairs (VA) medical centers (VAMCs) were surveyed in 2022 about implementing guideline-concordant cirrhosis care. VA Corporate Data Warehouse data were used to assess VAMC performance on two national cirrhosis quality measures: HCC surveillance and esophageal variceal surveillance or treatment (EVST). Organizational factors associated with higher performance were identified using linear regression models. RESULTS: Responding VAMCs (n = 124, 86%) ranged in resource availability, perceived barriers, and care processes. In multivariable models, factors independently associated with HCC surveillance included on-site interventional radiology and identifying patients overdue for surveillance using a national cirrhosis population management tool ("dashboard"). EVST was significantly associated with dashboard use and on-site gastroenterology services. For larger VAMCs, the average HCC surveillance rate was similar between VAMCs using vs. not using the dashboard (47% vs. 41%), while for smaller and less resourced VAMCs, dashboard use resulted in a 13% rate difference (46% vs. 33%). Likewise, higher EVST rates were more strongly associated with dashboard use in smaller (55% vs. 50%) compared to larger (57% vs. 55%) VAMCs. CONCLUSIONS: Resources, barriers, and care processes varied across diverse VAMCs. Smaller VAMCs without specialty care achieved HCC and EVST surveillance rates nearly as high as more complex and resourced VAMCs if they used a population management tool to identify the patients due for cirrhosis care.

RESUMO

BACKGROUND AND AIMS: The Veterans Health Administration (VHA) provides care for more than 80,000 veterans with cirrhosis. This longitudinal, multimethod evaluation of a cirrhosis care quality improvement program aimed to (1) identify implementation strategies associated with evidence-based, guideline-concordant cirrhosis care over time, and (2) use qualitative interviews to operationalize strategies for a manualized intervention. APPROACH AND RESULTS: VHA providers were surveyed annually about the use of 73 implementation strategies to improve cirrhosis care in fiscal years 2018 (FY18) and 2019 (FY19). Implementation strategies linked to guideline-concordant cirrhosis care were identified using bivariate statistics and comparative configurational methods. Semistructured interviews were conducted with 12 facilities in the highest quartile of cirrhosis care to specify the successful implementation strategies and their mechanisms of change. A total of 106 VHA facilities (82%) responded at least once over the 2-year period (FY18, n = 63; FY19, n = 100). Facilities reported using a median of 12 (interquartile range [IQR] 20) implementation strategies in FY18 and 10 (IQR 19) in FY19. Of the 73 strategies, 35 (48%) were positively correlated with provision of evidence-based cirrhosis care. Configurational analysis identified multiple strategy pathways directly linked to more guideline-concordant cirrhosis care. Across both methods, a subset of eight strategies was determined to be core to cirrhosis care improvement and specified using qualitative interviews. CONCLUSIONS: In a national cirrhosis care improvement initiative, a multimethod approach identified a core subset of successful implementation strategy combinations. This process of empirically identifying and specifying implementation strategies may be applicable to other implementation challenges in hepatology.

RESUMO

BACKGROUND: Chronic pain is common among patients with cirrhosis and is challenging to treat. While promising, pain self-management (PSM) interventions have not been tailored to this population's needs. AIMS: To design a PSM intervention for patients with cirrhosis. METHODS: Semi-structured interviews with 17 patients with cirrhosis, 12 hepatologists, and 6 administrators from two medical centers were conducted to inform a rigorous, structured intervention mapping (IM) process. Qualitative content analysis was guided by social cognitive theory (SCT) and the Consolidated Framework for Implementation Research (CFIR) and incorporated into intervention development. A planning group met regularly throughout the intervention, to reach consensus about how to use data and theory to develop the intervention through IM. RESULTS: Participants described barriers to PSM behaviors, including the absence of simple, evidence-based interventions for pain for patients with cirrhosis, inadequate provider knowledge, time, and training, and lack of champions, funding, and communication. Patients described high motivation to treat pain using behavioral methods including meditation, prayer, and exercise. The intervention was designed to address barriers to PSM behaviors for patients with cirrhosis, using behavior change methods that address knowledge, self-efficacy, and outcome expectations. The LEAP (Liver Education About Pain) intervention is a 12-week, modular intervention delivered by phone via individual and group sessions with a health coach. CONCLUSIONS: People with cirrhosis, hepatologists, and administrators informed this theory-driven, tailored PSM intervention, which was designed to be implementable in the real world.

RESUMO

BACKGROUND: Significant disparities in hepatitis C (HCV) treatment existed in the interferon treatment era, such that patients with mental health and substance use disorders were less likely to be treated. We aimed to evaluate whether these perceptions continue to influence HCV treatment decisions. METHODS: We e-mailed HCV providers a survey to assess their perceptions of barriers to HCV treatment adherence and initiation. We assessed the frequency of perceived barriers and willingness to initiate HCV treatment in patients with these barriers. We identified a group of providers more willing to treat patients with perceived barriers to adherence and determined the associated provider characteristics using Spearman's rho and Wilcoxon rank-sum tests. RESULTS: A total of 103 providers (29%) responded to the survey. The most commonly endorsed perceived barriers to adherence were homelessness (65%), ongoing drug (58%), and ongoing alcohol use (33%). However, 90%, 68%, and 90% of providers were still willing to treat patients with these comorbidities, respectively. Ongoing drug use was the most common reason providers were never or rarely willing to initiate HCV treatment. Providers who were less willing to initiate treatment more frequently endorsed patient-related determinants of adherence, while providers who were more willing to initiate treatment more frequently endorsed provider-based barriers to adherence (e.g., communication). CONCLUSIONS: Most responding providers were willing to initiate HCV treatment in all patients, despite the presence of perceived barriers to adherence or previous contraindications to interferon-based treatments. Ongoing substance use remains the most prominent influencer in the decision not to treat.

RESUMO

INTRODUCTION: Onabotulinumtoxin type A (BoNTA) is manufactured as powder that requires reconstitution with normal saline prior to injection. Previous literature has suggested that preserved saline (PS) exerts a local anaesthetic effect, and reduces the procedure discomfort when used in reconstitution in lieu of preservative-free saline (PFS). However, this was mainly studied in the aesthetics indications of BoNTA, and never in its use for the treatment of chronic migraine. The distinction is important as chronic migraine population suffers high incidence of scalp allodynia which makes it more prone to injection site pain. In addition, the pain of the procedure itself may be related to the spike of migraine frequency in the immediate postprocedural period which can occur in up to 5% of patients receiving the treatment. Our trial aimed to study the difference in procedural pain scale, and postprocedural headache rating with the use of PS vs PFS in constitution of BoNTA when used as a treatment for chronic migraine. METHODS: 68 subjects were consecutively enrolled in an outpatient setting at a large tertiary headache centre over a period of 6 months. Subjects were randomised into PS or PFS group. BoNTA was administered as per standard protocol in both groups. Injection site pain scores and frequency of headache days in the immediate following week were recorded. Wilcoxon rank sum tests were used to compare differences in between groups using SPSS software. RESULTS: Analysis (SAS V 9.4) revealed that those receiving [PF] had significantly higher procedure pain scores than those receiving [P] (5.3 vs 3.2, respectively). There was no difference in the headache or migraine frequency in the immediate postprocedural period. CONCLUSION: This study supports the use of PS (bacteriostatic) over PFS for reconstitution of BoNTA in chronic migraine as it reduces the discomfort of the injection sites.

RESUMO

BACKGROUND: Human papillomavirus 16 (HPV16) E6 antibodies may be an early marker of the diagnosis and recurrence of human papillomavirus-driven oropharyngeal cancer (HPV-OPC). METHODS: This study identified 161 incident oropharyngeal cancer (OPC) cases diagnosed at the University of Pittsburgh (2003-2013) with pretreatment serum. One hundred twelve had preexisting clinical HPV testing with p16 immunohistochemistry and HPV in situ hybridization (87 were dual-positive [HPV-OPC], and 25 were dual-negative [HPV-negative]); 62 had at least 1 posttreatment serum sample. Eighty-six of the 161 tumors were available for additional HPV16 DNA/RNA testing (45 were dual-positive [HPV16-OPC], and 19 were dual-negative [HPV16-negative). HPV16 E6 antibody testing was conducted with multiplex serology. The following were evaluated: 1) the sensitivity and specificity of HPV16 E6 serology for distinguishing HPV-OPC and HPV16-OPC from HPV-negative OPC, 2) HPV16 E6 antibody decay after treatment with linear models accommodating correlations in variance estimates, and 3) pre- and posttreatment HPV16 E6 levels and the risk of recurrence with Cox proportional hazards models. RESULTS: Seventy-eight of 87 HPV-OPCs were HPV16 E6-seropositive (sensitivity, 89.7%; 95% confidence interval [CI], 81.3%-95.2%), and 24 of 25 HPV-negative OPCs were HPV16 E6-seronegative (specificity, 96.0%; 95% CI, 79.6%-99.9%). Forty-two of 45 HPV16-OPCs were HPV16 E6-seropositive (sensitivity, 93.3%; 95% CI, 81.7%-98.6%), and 18 of 19 HPV16-negative OPCs were HPV16 E6-seronegative (specificity, 94.7%; 95% CI, 74.0%-99.9%). Posttreatment HPV16 E6 antibody levels did not decrease significantly from the baseline (P = .575; median follow-up, 307 days) and were not associated with the risk of recurrence. However, pretreatment HPV16 E6 seropositivity was associated with an 86% reduced risk of local/regional recurrence (hazard ratio, 0.14; 95% CI, 0.03-0.68; P = .015). CONCLUSIONS: HPV16 E6 antibodies may have potential clinical utility for the diagnosis and/or prognosis of HPV-OPC. Cancer 2017;123:4382-90. © 2017 American Cancer Society.

RESUMO

BACKGROUND: Squamous cell carcinoma of the head and neck (SCCHN) remains a prevalent and devastating disease. Recently, there has been an increase in SCCHN cases that are associated with high-risk human papillomavirus (HPV) infection. The clinical characteristics of HPV-positive and HPV-negative SCCHN are known to be different but their molecular features are only recently beginning to emerge. MicroRNAs (miRNAs, miRs) are small, non-coding RNAs that are likely to play significant roles in cancer initiation and progression where they may act as oncogenes or tumor suppressors. Previous studies in our laboratory showed that miR-363 is overexpressed in HPV-positive compared to HPV-negative SCCHN cell lines, and the HPV type 16-E6 oncoprotein upregulates miR-363 in SCCHN cell lines. However, the functional role of miR-363 in SCCHN in the context of HPV infection remains to be elucidated. METHODS: We analyzed miR-363 levels in SCCHN tumors with known HPV-status from The Cancer Genome Atlas (TCGA) and an independent cohort from our institution. Cell migration studies were conducted following the overexpression of miR-363 in HPV-negative cell lines. Bioinformatic tools and a luciferase reporter assay were utilized to confirm that miR-363 targets the 3'-UTR of myosin 1B (MYO1B). MYO1B mRNA and protein expression levels were evaluated following miR-363 overexpression in HPV-negative SCCHN cell lines. Small interfering RNA (siRNA) knockdown of MYO1B was performed to assess the phenotypic implication of reduced MYO1B expression in SCCHN cell lines. RESULTS: MiR-363 was found to be overexpressed in HPV-16-positive compared to the HPV-negative SCCHN tumors. Luciferase reporter assays performed in HPV-negative JHU028 cells confirmed that miR-363 targets one of its two potential binding sites in the 3'UTR of MYO1B. MYO1B mRNA and protein levels were reduced upon miR-363 overexpression in four HPV-negative SCCHN cell lines. Increased miR-363 expression or siRNA knockdown of MYO1B expression reduced Transwell migration of SCCHN cell lines, indicating that the miR-363-induced migration attenuation of SCCHN cells may act through MYO1B downregulation. CONCLUSIONS: These findings demonstrate that the overexpression of miR-363 reduces cellular migration in head and neck cancer and reveal the biological relationship between miR-363, myosin 1b, and HPV-positive SCCHN.

RESUMO

Vertically oriented and ordered GaAs nanowire arrays have been grown by the self-assisted mechanism using substrates prepared with nano-patterned oxide templates. Patterned Ga-assisted GaAs nanowire growth on (111) silicon by molecular beam epitaxy showed that the axial and radial growth rates increased with increasing interhole spacing. A model is described which accounts for the correlation of the final length and diameter with pattern pitch. The model considers that growth material is supplied by a secondary flux of both gallium and arsenic adatoms desorbing from the oxide surface between the nanowires which subsequently impinge on the liquid droplet and nanowire sidewalls. We show that shading of the incident and scattered flux by neighboring nanowires in the array can strongly affect the axial and radial growth rates, leading to significant differences in final nanowire morphologies.

RESUMO

The terms mainstream America and mainstream American are often used but infrequently defined. The purpose of this study was to explore definitions of these terms among a multiethnic sample of 158 college students. Two major themes emerged from a qualitative analysis: 1) an exclusionary definition as U.S.-born, dominated by Whites and of Judeo-Christian faith versus the predominant, more inclusive, contemporary definition of sharing American values and practices within a diverse society and 2) a contrast between highly critical comments (weakened family ties, moral decay, racism) and favorable comments (opportunity, helpfulness, openness and inclusiveness). Responses by ethnic group were also reported.

RESUMO

A 33-year-old woman with relapsing remitting multiple sclerosis who was on fingolimod for 5 years presented with a solitary skin lesion on her abdomen (Figure 1) for 2 months, which was unresponsive to antibiotics. The neurologic examination was normal. She denied having infectious symptoms, chest pain, shortness of breath, recent travel, trauma to the area, or animal exposure. Her most recent absolute lymphocyte count was 0.22 × 109/L (reference 1.2-4.0 109/L). The differential diagnosis included skinfold friction, dermatofibroma, pyoderma gangrenosum, and basal cell carcinoma. Although a dermatologist did not initially recommend a biopsy because the lesion was not ulcerated, she obtained one based on the recommendation of her neurologist. Shave biopsy revealed cryptococcal fungal infection (Figure 2). There was no evidence of asymptomatic disseminated cryptococcus. The proposed mechanism for the lesion involves a latent infection while immunocompetent with reactivation once immunocompromised.1 Cryptococcus infections are associated with immunosuppression, most often due to human immunodeficiency virus infection, and only 6 fingolimod-associated cutaneous infections have been reported in the literature.2 Patients with MS on immunosuppressant medication should be carefully screened for cutaneous infections.

RESUMO

BACKGROUND: The Expert Recommendations for Implementing Change (ERIC) compilation includes 73 defined implementation strategies clustered into nine content areas. This taxonomy has been used to track implementation strategies over time using surveys. This study aimed to improve the ERIC survey using cognitive interviews with non-implementation scientist clinicians. METHODS: Starting in 2015, we developed and fielded annual ERIC surveys to evaluate liver care in the Veterans Health Administration (VA). We invited providers who had completed at least three surveys to participate in cognitive interviews (October 2020 to October 2021). Before the interviews, participants reviewed the complete 73-item ERIC survey and marked which strategies were unclear due to wording, conceptual confusion, or overlap with other strategies. They then engaged in semi-structured cognitive interviews to describe the experience of completing the survey and elaborate on which strategies required further clarification. RESULTS: Twelve VA providers completed surveys followed by cognitive interviews. The "Engage Consumer" and "Support Clinicians" clusters were rated most highly in terms of conceptual and wording clarity. In contrast, the "Financial" cluster had the most wording and conceptual confusion. The "Adapt and Tailor to Context" cluster strategies were considered to have the most redundancy. Providers outlined ways in which the strategies could be clearer in terms of wording (32%), conceptual clarity (51%), and clarifying the distinction between strategies (51%). CONCLUSIONS: Cognitive interviews with ERIC survey participants allowed us to identify and address issues with strategy wording, combine conceptually indistinct strategies, and disaggregate multi-barreled strategies. Improvements made to the ERIC survey based on these findings will ultimately assist VA and other institutions in designing, evaluating, and replicating quality improvement efforts.

RESUMO

BACKGROUND: Practical and feasible methods for matching implementation strategies to diagnosed barriers of evidence-based interventions in real-world contexts are lacking. This evaluation compared actual implementation strategies applied with those recommended by an expert opinion-based tool to improve guideline-concordant cirrhosis care in a Veterans Health Administration national learning collaborative effort. METHODS: This convergent parallel mixed-methods study aimed to (1) identify pre-implementation Consolidated Framework for Implementation Research (CFIR) barriers to cirrhosis care through focus groups with frontline providers, (2) generate 20 recommended strategies using focus group identified barriers entered into the CFIR-Expert Recommendations for Implementing Change (ERIC) Implementation Strategy Matching Tool, (3) survey providers over two consecutive years on the actual use of 73 ERIC strategies and determine strategy effectiveness, (4) compare actual versus recommended strategy use, and (5) compare actual versus expected barriers by reverse applying the CFIR-ERIC Matching Tool. RESULTS: Eighteen semi-structured focus groups were conducted with 197 providers representing 95 VA sites to identify barriers to quality improvement, including cirrhosis care complexity, clarity of national goals, and local leadership support. The CFIR-ERIC Matching Tool recommended strategies such as assessing for readiness and needs, promoting adaptability, building local groups, preparing champions, and working with opinion leaders and early adopters. Subsequent strategy surveys found that sites used the top 20 "recommended" strategies no more frequently than other strategies. However, 14 (70%) of the top recommended strategies were significantly positively associated with cirrhosis care compared to 48% of actual strategies. Reverse CFIR-ERIC matching found that the strategies most used in the first year corresponded to the following barriers: opinion leaders, access to knowledge and information, and resources. The strategies most frequently employed in the second year addressed barriers such as champions, cosmopolitanism, readiness for implementation, relative priority, and patient needs and resources. Strategies used in both years were those that addressed adaptability, trialability, and compatibility. CONCLUSIONS: This study is among the first to empirically evaluate the relationship between CFIR-ERIC Matching Tool recommended strategies and actual strategy selection and effectiveness in the real world. We found closer connections between recommended strategies and strategy effectiveness compared to strategy frequency, suggesting validity of barrier identification, and application of the expert-informed tool.

RESUMO

Introduction: Implementation strategies supporting the translation of evidence into practice need to be tailored and adapted for maximum effectiveness, yet the field of adapting implementation strategies remains nascent. We aimed to adapt "Getting To Outcomes"® (GTO), a 10-step implementation playbook designed to help community-based organizations plan and evaluate behavioral health programs, into "Getting To Implementation" (GTI) to support the selection, tailoring, and use of implementation strategies in health care settings. Methods: Our embedded evaluation team partnered with operations, external facilitators, and site implementers to employ participatory methods to co-design and adapt GTO for Veterans Health Administration (VA) outpatient cirrhosis care improvement. The Framework for Reporting Adaptations and Modifications to Evidenced-based Implementation Strategies (FRAME-IS) guided documentation and analysis of changes made pre- and post-implementation of GTI at 12 VA medical centers. Data from multiple sources (interviews, observation, content analysis, and fidelity tracking) were triangulated and analyzed using rapid techniques over a 3-year period. Results: Adaptations during pre-implementation were planned, proactive, and focused on context and content to improve acceptability, appropriateness, and feasibility of the GTI playbook. Modifications during and after implementation were unplanned and reactive, concentrating on adoption, fidelity, and sustainability. All changes were collaboratively developed, fidelity consistent at the level of the facilitator and/or implementer. Conclusion: GTO was initially adapted to GTI to support health care teams' selection and use of implementation strategies for improving guideline-concordant medical care. GTI required ongoing modification, particularly in steps regarding team building, context assessment, strategy selection, and sustainability due to difficulties with step clarity and progression. This work also highlights the challenges in pragmatic approaches to collecting and synthesizing implementation, fidelity, and adaptation data. Trial registration: This study was registered on ClinicalTrials.gov (Identifier: NCT04178096).

RESUMO

There are an increasing number of students with learning difficulties attending university, and currently much debate about the suitability and ability of students with dyslexia at both medical school and once they graduate into clinical practice. In this study we describe the performance of students with dyslexia compared to fellow students in extended matching questions (EMQ), short answer question (SAQ) and observed structured clinical examinations (OSCE) and discuss the implications of differences identified. End of year assessment results for 5 cohorts of medical students were analysed. Students with dyslexia did less well overall in all assessment types in year 1 but this difference was not evident in later years. Dyslexic students who were allowed extra time in written assessments did better than dyslexic students who did not have their assessment concessions in place. When station type within OSCE assessments was analysed students with dyslexia did less well in both examination skills and data interpretation stations in years 1, 2 & 3. In conclusion, differences in performance in written assessments are only evident early in training and may be partly due to delayed adjustment to medical school or implementation of assessment concessions. Performance in individual OSCE stations is dependent on station type. Why students with specific learning difficulties (SpLDs) perform less well in examination skills and data analysis OSCE stations requires further investigation.

RESUMO

The aim of this study was to describe a homeless population's lived experience with substance abuse. A retrospective descriptive design was used to collect data from a sample of 75 homeless adults participating in a community-based homeless recovery residential program. Each participant was interviewed concerning gender, age, marital status, race, religion, education, employment, substance abuse, family history, psychiatric history, and legal history. Characteristics that emerged from the data were grouped into categories using content analysis. Seventy-three of the 75 homeless participants reported a history of substance abuse and provided in-depth descriptions of issues concerning their substance abuse.

RESUMO

After implementing a successful hepatitis C elimination program, the Veterans Health Administration's (VHA) Hepatic Innovation Team (HIT) Collaborative pivoted to focus on improving cirrhosis care. This national program developed teams of providers across the country and engaged them in using systems redesign methods and population health approaches to improve care. The HIT Collaborative developed an Advanced Liver Disease (ALD) Dashboard to identify Veterans with cirrhosis who were due for surveillance for hepatocellular carcinoma (HCC) and other liver care, promoted the use of an HCC Clinical Reminder in the electronic health record, and provided training and networking opportunities. This evaluation aimed to describe the VHA's approach to improving cirrhosis care and identify the facility factors and HIT activities associated with HCC surveillance rates, using a quasi-experimental design. Across all VHA facilities, as the HIT focused on cirrhosis between 2018-2019, HCC surveillance rates increased from 46% (IQR 37-53%) to 51% (IQR 42-60%, p < 0.001). The median HCC surveillance rate was 57% in facilities with high ALD Dashboard utilization compared with 45% in facilities with lower utilization (p < 0.001) and 58% in facilities using the HCC Clinical Reminder compared with 47% in facilities not using this tool (p < 0.001) in FY19. Increased use of the ALD Dashboard and adoption of the HCC Clinical Reminder were independently, significantly associated with HCC surveillance rates in multivariate models, controlling for other facility characteristics. In conclusion, the VHA's HIT Collaborative is a national healthcare initiative associated with significant improvement in HCC surveillance rates.

RESUMO

BACKGROUND AND AIMS: The Veterans Health Administration (VA) cares for over 80,000 Veterans with cirrhosis annually. Given the importance of understanding patient reported outcomes in this complex population, we aimed to assess the associations between attitudes towards care, disease knowledge, and health related quality of life (HRQoL) in a national sample. METHODS: In this cross-sectional study, we mailed paper surveys to a random sample of Veterans with cirrhosis, oversampling those with decompensated disease. Surveys included the Veterans RAND 12-Item Health Survey (measuring HRQoL) and questions about demographics, characteristics of care, satisfaction with care ("attitudes towards care"), and symptoms of cirrhosis. Those who reported being "unsure" about whether they had decompensation events were defined as "unsure about cirrhosis symptoms" ("disease knowledge"). We used multivariable regression models to assess the factors associated with HRQoL. RESULTS: Of 1374 surveys, 551 (40%) completed surveys were included for analysis. Most Veterans (63%) were "satisfied" or "very satisfied" with VA liver care. Patients often self-reported being unsure about whether they had experienced hepatic decompensation events (34%). Overall average physical (PCS) and mental (MCS) component scores of HRQoL were 30±11 and 41±12. In multivariable regression models, hepatic decompensation (PCS:ß = -3.8, MCS:ß = -2.2), medical comorbidities (ß = --2.0, ß = -1.7), and being unsure about cirrhosis symptoms (ß = -1.9, ß = -3.3) were associated with worse HRQoL, while age (ß = 0.1, ß = 0.2) and satisfaction with care (ß = 0.6; ß = 1.6) were associated with significantly better HRQoL. CONCLUSIONS: Hepatic decompensation, lower satisfaction with care, and being unsure about cirrhosis symptoms were associated with reduced QOL scores in this national cohort.

RESUMO

BACKGROUND: Cirrhosis is a rapidly increasing cause of global mortality. To improve cirrhosis care, the Veterans Health Administration (VHA) developed the Hepatic Innovation Team (HIT) Collaborative to support VA Medical Centers (VAMCs) to deliver evidence-based cirrhosis care. This randomized HIT program evaluation aims to develop and assess a novel approach for choosing and applying implementation strategies to improve the quality of cirrhosis care. METHODS: Evaluation aims are to (1) empirically determine which combinations of implementation strategies are associated with successful implementation of evidence-based practices (EBPs) for Veterans with cirrhosis, (2) manualize these "data-driven" implementation strategies, and (3) assess the effectiveness of data-driven implementation strategies in increasing cirrhosis EBP uptake. Aim 1 will include an online survey of all VAMCs' use of 73 implementations strategies to improve cirrhosis care, as defined by the Expert Recommendations for Implementing Change taxonomy. Traditional statistical as well as configurational comparative methods will both be employed to determine which combinations of implementation strategies are associated with site-level adherence to EBPs for cirrhosis. In aim 2, semi-structured interviews with high-performing VAMCs will be conducted to operationalize successful implementation strategies for cirrhosis care. These data will be used to inform the creation of a step-by-step guide to tailoring and applying the implementation strategies identified in aim 1. In aim 3, this manualized implementation intervention will be assessed using a hybrid type III stepped-wedge cluster randomized design. This evaluation will be conducted in 12 VAMCs, with four VAMCs crossing from control to intervention every 6 months, in order to assess the effectiveness of using data-driven implementation strategies to improve guideline-concordant cirrhosis care. DISCUSSION: Successful completion of this innovative evaluation will establish the feasibility of using early evaluation data to inform a manualized, user-friendly implementation intervention for VAMCs with opportunities to improve care. This evaluation will provide implementation support tools that can be applied to enhance the implementation of other evidence-based practices. TRIAL REGISTRATION: This project was registered at ClinicalTrials.Gov ( NCT04178096 ) on 4/29/20.

RESUMO

Intergenerational communication between teacher and student is especially important today, because of the gaps of time and understanding that exist among four active generations--Traditionalist, Baby Boomers, Generation X, and Millennials. Faculty have opportunities to be successful by learning the values, learning styles, past generational experiences, and current expectations of today's highly technologically competent students. Recommendations are offered for communication strategies in schools of nursing.

RESUMO

Superconducting nanowire single-photon detectors with peak efficiencies above 90% and unrivalled timing jitter (<30 ps) have emerged as a potent technology for quantum information and sensing applications. However, their high cost and cryogenic operation limit their widespread applicability. Here, we present an approach using tapered InP nanowire p-n junction arrays for high-efficiency, broadband and high-speed photodetection without the need for cryogenic cooling. The truncated conical nanowire shape enables a broadband, linear photoresponse in the ultraviolet to near-infrared range (~500 nm bandwidth) with external quantum efficiencies exceeding 85%. The devices exhibit a high gain beyond 105, such that a single photon per pulse can be distinguished from the dark noise, while simultaneously showing a fast pulse rise time (<1 ns) and excellent timing jitter (<20 ps). Such detectors open up new possibilities for applications in remote sensing, dose monitoring for cancer treatment, three-dimensional imaging and quantum communication.
