- Abstract
Objective: To use a practical approach to examining the use of Expert Recommendations for Implementing Change (ERIC) strategies by Reach, Effectiveness, Adoption, Implementation, and Maintenance (RE-AIM) dimensions for rural health innovations using annual reports on a diverse array of initiatives., Data Sources and Study Setting: The Veterans Affairs (VA) Office of Rural Health (ORH) funds initiatives designed to support the implementation and spread of innovations and evidence-based programs and practices to improve the health of rural Veterans. This study draws on the annual evaluation reports submitted for fiscal years 2020-2022 from 30 of these enterprise-wide initiatives (EWIs)., Study Design: Content analysis was guided by the RE-AIM framework conducted by the Center for the Evaluation of Enterprise-Wide Initiatives (CEEWI), a Quality Enhancement Research Initiative (QUERI)-ORH partnered evaluation initiative., Data Collection and Extraction Methods: CEEWI analysts conducted a content analysis of EWI annual evaluation reports submitted to ORH. Analysis included cataloguing reported implementation strategies by Reach, Adoption, Implementation, and Maintenance (RE-AIM) dimensions (i.e., identifying strategies that were used to support each dimension) and labeling strategies using ERIC taxonomy. Descriptive statistics were conducted to summarize data., Principal Findings: A total of 875 implementation strategies were catalogued in 73 reports. Across these strategies, 66 unique ERIC strategies were reported. EWIs applied an average of 12 implementation strategies (range 3-22). The top three ERIC clusters across all 3 years were Develop stakeholder relationships (21%), Use evaluative/iterative strategies (20%), and Train/educate stakeholders (19%). Most strategies were reported within the Implementation dimension. Strategy use among EWIs meeting the rurality benchmark were also compared., Conclusions: Combining the dimensions from the RE-AIM framework and the ERIC strategies allows for understanding the use of implementation strategies across each RE-AIM dimension. This analysis will support ORH efforts to spread and sustain rural health innovations and evidence-based programs and practices through targeted implementation strategies., (Published 2024.

- Abstract
Background: Communication is considered an inherent element of nearly every implementation strategy. Often it is seen as a means for imparting new information between stakeholders, representing a Transaction orientation to communication. From a Process orientation, communication is more than information-exchange and is acknowledged as being shaped by (and shaping) the individuals involved and their relationships with one another. As the field of Implementation Science (IS) works to strengthen theoretical integration, we encourage an interdisciplinary approach that engages communication theory to develop richer understanding of strategies and determinants of practice., Methods: We interviewed 28 evaluators, 12 implementors, and 12 administrators from 21 Enterprise-Wide Initiatives funded by the Department of Veteran Affairs Office of Rural Health. Semi-structured interviews focused on experiences with implementation and evaluation strategies. We analyzed the interviews using thematic analysis identifying a range of IS constructs. Then we deductively classified those segments based on a Transaction or Process orientation to communication., Results: We organized findings using the two IS constructs most commonly discussed in interviews: Collaboration and Leadership Buy-in. The majority of segments coded as Collaboration (n = 34, 74%) and Leadership Buy-in (n = 31, 70%) discussed communication from a Transaction orientation and referred to communication as synonymous with information exchange, which emphasizes the task over the relationships between the individuals performing the tasks. Conversely, when participants discussed Collaboration and Leadership Buy-in from a Process orientation, they acknowledged both constructs as the result of long-term efforts to develop positive relationships based on trust and respect, and emphasized the time costliness of such strategies. Our findings demonstrate that participants who discussed communication from a Process orientation recognized the nuance and complexity of interpersonal interactions, particularly in the context of IS., Conclusions: Efficient, reliable information exchange is a critical but often overemphasized element of implementation. Practitioners and researchers must recognize and incorporate the larger role of communication in IS. Two suggestions for engaging a Process orientation to communication are to: (a) use interview probes to learn how communication is enacted, and (b) use process-oriented communication theories to develop interventions and evaluation tools., (© 2024.

- Abstract
Objectives: Women veterans are more likely than men veterans to receive medications that Department of Veterans Affairs clinical practice guidelines recommend against to treat posttraumatic stress disorder (PTSD). To understand this difference, we examined potential confounders in incident prescribing of guideline discordant medications (GDMs) in veterans with PTSD., Methods: Veterans receiving care for PTSD during 2020 were identified using Veterans Health Administration administrative data. PTSD diagnosis was established by the presence of at least 1 ICD-10 coded outpatient encounter or inpatient hospitalization during the calendar year 2020. Incident GDM prescribing was assessed during 2021, including benzodiazepines, antipsychotics, select anticonvulsants, and select antidepressants. Log-binomial regression was used to estimate the difference in risk for GDM initiation between men and women, adjusted for patient, prescriber, and facility-level covariates, and to identify key confounding variables., Results: Of 704,699 veterans with PTSD, 16.9% of women and 10.1% of men initiated a GDM, an increased risk of 67% for women [relative risk (RR) = 1.67; 95% CI, 1.65-1.70]. After adjustment, the gender difference decreased to 1.22 (95% CI, 1.20-1.24) in a fully specified model. Three key confounding variables were identified: bipolar disorder (RR = 1.60; 95% CI, 1.57-1.63), age (<40 years: RR = 1.20 [1.18-1.22]; 40-54 years: RR = 1.13 [1.11-1.16]; ≥65 years: RR = 0.64 [0.62-0.65]), and count of distinct psychiatric medications prescribed in the prior year (RR = 1.14; 1.13-1.14)., Conclusions: Women veterans with PTSD were 67% more likely to initiate a GDM, where more than half of this effect was explained by bipolar disorder, age, and prior psychiatric medication. After adjustment, women veterans remained at 22% greater risk for an incident GDM, suggesting that other factors remain unidentified and warrant further investigation., (© Copyright 2024 Physicians Postgraduate Press, Inc.)

- Abstract
Background: The Department of Veterans Affairs (VA) Office of Rural Health (ORH) supports national VA program offices' efforts to expand health care to rural Veterans through its Enterprise-Wide Initiatives (EWIs) program. In 2017, ORH selected Reach, Effectiveness, Adoption, Implementation, and Maintenance (RE-AIM), an implementation science framework, to structure the EWI evaluation and reporting process. As part of its mandate to improve EWI program evaluation, the Center for the Evaluation of Enterprise-Wide Initiatives conducted a qualitative evaluation to better understand EWI team' perceptions of, and barriers and facilitators to, the EWI evaluation process., Methods: We conducted 43 semi-structured interviews with 48 team members (e.g., evaluators, program office leads, and field-based leads) representing 21 EWIs from April-December 2020. Questions focused on participants' experiences using strategies targeting each RE-AIM dimension. Interviews were inductively analyzed in MAXQDA. We also systematically reviewed 51 FY19-FY20 EWI annual reports to identify trends in misapplications of RE-AIM., Results: Participants had differing levels of experience with RE-AIM. While participants understood ORH's rationale for selecting a common framework to structure evaluations, the perceived misalignment between RE-AIM and EWIs' work emerged as an important theme. Concerns centered around 3 sub-themes: (1) (Mis)Alignment with RE-AIM Dimensions , (2) (Mis)Alignment between RE-AIM and the EWI , and (3) (Mis)Alignment with RE-AIM vs. other Theories, Models, or Frameworks . Participants described challenges differentiating between and operationalizing dimensions in unique contexts. Participants also had misconceptions about RE-AIM and its relevance to their work, e.g., that it was meant for established programs and did not capture aspects of initiative planning, adaptations, or sustainability. Less commonly, participants shared alternative models or frameworks to RE-AIM. Despite criticisms, many participants found RE-AIM useful, cited training as important to understanding its application, and identified additional training as a future need., Discussion: The selection of a shared implementation science framework can be beneficial, but also challenging when applied to diverse initiatives or contexts. Our findings suggest that establishing a common understanding, operationalizing framework dimensions for specific programs, and assessing training needs may better equip partners to integrate a shared framework into their evaluations., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (© 2024 Chasco, Van Tiem, Johnson, Balkenende, Steffen, Jones, Friberg, Steffensmeier, Moeckli, Arora, Rabin and Reisinger.)

- Abstract
Background: There are a range of effective pharmacological and behavioral treatments for depression. However, approximately one-third of patients discontinue antidepressants within the first month of treatment and 44% discontinue them by the third month of treatment. The major reasons reported for discontinuation were side effect burden, patients experiencing that the medications were not working, and patients wanting to resolve their depression without using medication., Objective: This study tested the acceptability, feasibility, and preliminary effectiveness of an SMS messaging intervention designed to improve antidepressant adherence and depression outcomes in veterans. The intervention specifically targeted the key reasons for antidepressant discontinuation. For example, the secure message included reminders that it can take up to 6 weeks for an antidepressant to work, or prompts to call their provider should the side effect burden become significant., Methods: This pilot was a 3-armed randomized controlled trial of 53 veterans undergoing depression treatment at the Iowa City Veterans Affairs Health Care System. Veterans starting a new antidepressant were randomized to secure messaging only (SM-Only), secure messaging with coaching (SM+Coach), or attention control (AC) groups. The intervention lasted 12 weeks with follow-up assessments of key outcomes at 6 and 12-weeks. This included a measure of antidepressant adherence, depressive symptom severity, and side effect burden., Results: The 2 active interventions (SM-Only and SM+Coach) demonstrated small to moderate effect sizes (ESs) in improving antidepressant adherence and reducing side effect burden. They did not appear to reduce the depressive symptom burden any more than in the AC arm. Veteran participants in the SM arms demonstrated improved medication adherence from baseline to 12 weeks on the Medication Adherence Rating Scale compared with those in the AC arm, who had a decline in adherence (SM-Only: ES=0.09; P=.19; SM+Coach: ES=0.85; P=.002). Depression scores on the 9-Item Patient Health Questionnaire decreased for all 3 treatment arms, although the decline was slightly larger for the SM-Only (ES=0.32) and the SM+Coach (ES=0.24) arms when compared with the AC arm. The 2 intervention arms indicated a decrease in side effects on the Frequency, Intensity, and Burden of Side Effects Ratings, whereas the side effect burden for the AC arm increased. These differences indicated moderate ES (SM-Only vs AC: ES=0.40; P=.07; SM+Coach: ES=0.54; P=.07)., Conclusions: A secure messaging program targeting specific reasons for antidepressant discontinuation had small-to-moderate ES in improving medication adherence. Consistent with prior research, the intervention that included brief synchronic meetings with a coach appeared to have a greater benefit than the SMS-alone intervention. Veterans consistently engaged with the SMS messaging in both treatment arms throughout the study period. They additionally provided feedback on which texts were most helpful, tending to prefer messages providing overall encouragement rather than specific wellness recommendations., Trial Registration: ClinicalTrials.gov NCT03930849; https://clinicaltrials.gov/study/NCT03930849., (©Carolyn Turvey, Lindsey Fuhrmeister, Dawn Klein, Kimberly McCoy, Jane Moeckli, Kenda R Stewart Steffensmeier, Natalie Suiter, Jen Van Tiem.

- Abstract
Purpose: This qualitative analysis of interviews with surgical patients who received a brief perioperative psychological intervention, in conjunction with standard medical perioperative care, elucidates patient perspectives on the use of pain self-management skills in relation to postoperative analgesics., Design: This study is a secondary analysis of qualitative data from a randomized controlled trial., Methods: Participants (N = 21) were rural-dwelling United States Military Veterans from a mixed surgical sample who were randomized to receive a manual-based, telephone-based Perioperative Pain Self-management intervention consisting of a total of four pre- and postoperative contacts. Semi-structured qualitative interviews elicited participant feedback on the cognitive-behavioral intervention. Data was analyzed by two qualitative experts using MAXQDA software. Key word analyses focused on mention of analgesics in interviews., Findings: Interviews revealed a dominant theme of ambivalence towards postoperative use of opioids. An additional theme concerned the varied ways acquiring pain self-management skills impacted postoperative opioid (and non-opioid analgesic) consumption. Participants reported that employment of pain self-management strategies reduced reliance on pharmacology for pain relief, prolonged the time between doses, took the "edge off" pain, and increased pain management self-efficacy., Conclusions: Perioperative patient education may benefit from inclusion of teaching non-pharmacologic pain self-management skills and collaborative planning with patients regarding how to use these skills in conjunction with opioid and non-opioid analgesics. Perianesthesia nurses may be in a critical position to provide interdisciplinary postoperative patient education that may optimize postoperative pain management while minimizing risks associated with prolonged opioid use., (Published by Elsevier Inc.)

- Abstract
Background: The Measurement Based Care in Mental Health Initiative launched by the Department of Veterans Affairs in 2016 is an example of an evidence-based practice that uses patient-reported outcome measures (PROMs) to improve patient outcomes. The acceptance of measurement-based care (MBC) among Veterans Affairs providers is relatively high. However, there are barriers to MBC for telehealth providers. Health information technologies might afford opportunities to address some of the barriers related to the uptake of MBC., Objective: This paper reports on an implementation effort to integrate MBC into mental health care telehealth practice using eHealth solutions., Methods: Qualitative data were generated from 22 semistructured interviews with psychiatrists (n=4), psychologists (n=3), social workers (n=3), nurses (n=6), a pharmacist (n=1), and administrative staff (n=5) who provide telemental health care through a community-based outpatient clinic in the rural Midwestern United States. The interviews were conducted during the pilot phase of an implementation initiative to increase the adoption of MBC by revising clinic workflows to integrate the use of eHealth technologies. Data were analyzed using thematic analysis., Results: Time burden and workflow issues were the most common barrier to provider adoption of MBC; sharing and reviewing pencil-and-paper measures and results in the same room was no longer possible in novel telehealth workflows necessitated by the COVID-19 pandemic. Providers voiced concerns about how long it would take to collect, adequately score, interpret, share, and document the PROMs during the telehealth visit. Concerns about time might also correspond to a gap in providers' familiarity with these assessments, greater comfort in assessing symptoms through clinical interviews, and being accustomed to using the assessments as screening tools more so than longitudinal outcome measures. Capacities associated with eHealth technologies may address workflow concerns and promote providers' understanding and use of the measures as tracking tools., Conclusions: The need to use limited appointment time well was a top priority for telemental health providers. eHealth technologies provided operative supports that protect time in appointments by shifting when and how PROMs are collected. Bolstering providers' familiarity with how to use PROMs in the course of treatment may impact providers' buy-in by encouraging them to reconsider how sharing and acting on PROMs could be time well spent., (©Jen Van Tiem, Elizabeth Wirtz, Natalie Suiter, Amanda Heeren, Lindsey Fuhrmeister, John Fortney, Heather Reisinger, Carolyn Turvey.

- Abstract
Purpose: Preoperatively distressed patients are at elevated risk for chronic postsurgical pain. Active psychological interventions show promise for mitigating chronic postsurgical pain. This study describes experiences of preoperatively distressed (elevated depressive symptom, anxious symptoms, or pain catastrophizing) and non-distressed participants who participated in the psychologically based Perioperative Pain Self-management (PePS) intervention., Design: This is a qualitative study designed to capture participants' perspectives and feedback about their experiences during the PePS intervention., Methods: Interviews were semi-structured, conducted by telephone, audio-recorded, transcribed, and audited for accuracy. Coded interviews were analyzed using a quote matrix to discern possible qualitative differences in what preoperatively distressed and non-distressed participants found most and least helpful about the intervention., Results: Twenty-one participants completed interviews, 7 of whom were classified as distressed. Distressed participants identified learning how to reframe their pain as the most helpful part of the intervention. Non-distressed participants focused on the benefit of relaxation skill-building to manage post-surgical pain. Distressed and non-distressed participants both emphasized the importance of the social support aspects of PePS and- identified goal-setting as challenging., Conclusions: Distressed and non-distressed participants emphasized different preferences for pain management strategies offered by PePS. Most participants emphasized the importance of social support that PePS provided., Clinical Implications: Our results indicate that post-operative patients may benefit from interpersonal interaction with a trained interventionist. Our findings also suggest that distressed and non-distressed patients may benefit from varied intervention approaches. How to build flexibility into a manualized intervention or whether these subsets of patients would benefit more from different interventions is a direction for future research., Competing Interests: Declaration of Competing Interest None, (Published by Elsevier Inc.)

- Abstract
Objective: The current study aimed to pilot the PePS intervention, based on principles of cognitive behavioral therapy (CBT), to determine feasibility and preliminary efficacy for preventing chronic pain and long-term opioid use., Summary Background Data: Surgery can precipitate the development of both chronic pain and long-term opioid use. CBT can reduce distress and improve functioning among patients with chronic pain. Adapting CBT to target acute pain management in the postoperative period may impact longer-term postoperative outcomes., Methods: This was a mixed-methods randomized controlled trial in a mixed surgical sample with assignment to standard care or PePS, with primary outcomes at 3-months postsurgery. The sample consisted of rural-dwelling United States Military Veterans., Results: Logistic regression analyses found a significant effect of PePS on odds of moderate-severe pain (on average over the last week) at 3-months postsurgery, controlling for preoperative moderate-severe pain: Adjusted odds ratio = 0.25 (95% CI: 0.07-0.95, P < 0.05). At 3-months postsurgery, 15% (6/39) of standard care participants and 2% (1/45) of PePS participants used opioids in the prior seven days: Adjusted Odds ratio = 0.10 (95% CI: 0.01-1.29, P = .08). Changes in depression, anxiety, and pain catastrophizing were not significantly different between arms., Conclusions: The findings from this study support the feasibility and preliminary efficacy of the PePS intervention., Competing Interests: The authors report no conflicts of interest., (Copyright © 2020 Wolters Kluwer Health, Inc.

- Abstract
Background: The effectiveness of technology-assisted interventions designed to ameliorate depressive symptoms and improve antidepressant medication adherence is hampered by diminished usage over time and poor integration with clinical care., Objective: This manuscript presents patient perspectives on a texting and secure messaging intervention designed to engage providers and patients during a targeted transition period when patients were initiating a new antidepressant medication., Patient Involvement: Development of the intervention was guided by feedback from a presentation and discussion with an engagement panel of local stakeholders, including patients, who meet quarterly with research investigators., Methods: Semi-structured, qualitative, telephone interviews were conducted with 21 participants. Interviews were designed to identify the themes of self-determination and planned behavior in using the text messaging intervention. Qualitative analysis of participants' experiences used inductive and deductive coding, as well as pile sorting., Results: The intervention prompted participants to reflect about how they manage their mood, engage in behaviors guided by their values, and commit to making positive changes in how they acted in real-time. Elements of the intervention facilitated participant conversations with trusted friends and family over time about what had influenced their actions and feelings., Discussion: The texting intervention appeared to help participants live a life consistent with their values. However, we were unable to recruit mental health providers to participate., Practical Value: Technology to promote self-reflection and an "observing self" may work best when done in dialogue with important others, including mental health providers. Future directions of this research should find ways to understand provider buy-in, or lack thereof, in e-health interventions., (Published by Elsevier B.V.)

- Abstract
This ethnographically informed implementation analysis of Parachute NYC between 2012 and 2015 documents the obstacles that can impede disruptive innovations in public mental health. Parachute combined family-based dialogic practice with peer-staffed crisis respite centers and mixed teams of clinicians and peers in an ambitious effort to revamp responses to psychiatric crises. This Open Forum reviews the demands posed by formidable contextual constraints, extended trainings in novel therapeutic techniques, and the effort to ensure sustainability in a managed care environment. It cautions that requiring innovations to produce evidence under the structural constraints that Parachute endured hobbles the effort and thwarts its success. The dialogic embrace of ordinary people and the use of peer labor as active treatment agents promote a slower and more participatory approach to psychiatric crises that offers extraordinary promise. However, a better prepared and more receptive context is needed for a fair trial of the comparative effectiveness of this approach.

- Abstract
The sensitivity and specificity of the ELISA and fecal culture tests for paratuberculosis in dairy cattle are examined. ELISA and fecal culture data from seven dairy herds where both fecal cultures and ELISA testing was done concurrently are included. A cohort of 954 cattle including 697 parturient adults, cultured every 6 months from 10 herds followed over 4 years served as the basis to determine fecal culture sensitivity. The fecal culture technique utilized a 2g sample with centrifugation and double incubation. Of the 954 cattle cohort of all ages (calf to adult) that were fecal sampled on the first herd visit, 79 were culture positive. An additional 131 animals were detected as culture positive over the next seven tests at 6-month intervals. The sensitivity of fecal culture to detect infected cattle on the first sampling was 38%. Of the 697 parturient cattle cohort, 67 were positive on the first fecal culture, while an additional 91 adult cattle were culture positive over the next seven tests, resulting in a sensitivity of 42% on the first culture of the total animals identified as culture positive. Animals culled from the herds prior to being detected as infected and animals always fecal culture negative with culture positive tissues at slaughter are not included in the calculations. Both groups of infected cattle will lower the apparent sensitivity of fecal culture. Infected dairy herds tested concurrently with both fecal culture and ELISA usually resulted in more than twofold positive animals by culture compared to ELISA. The classification of infected cattle by the extent of shedding of Mycobacterium paratuberculosis in the feces helps define the relative proportion of cattle in each group and therefore the likelihood of detection by the ELISA test. ELISA has a higher sensitivity in animals with a heavier bacterial load, i.e. high shedders (75%) compared to low shedders (15%). Repeated testing of infected herds identifies a higher proportion of low shedders which are more likely to be ELISA negative. Thus, the sensitivity of the ELISA test decreases with repeated herd testing over time, since heavy shedders will be culled first from the herds.
