Evaluating the implementation of a community health worker-delivered intervention integrating asthma care in West Philadelphia public schools.

OBJECTIVE: Schools are an important setting because students spend much of their time in school and engage in physical activity during the school day that could exacerbate asthma symptoms. Our objective is to understand the barriers and facilitators to implementing an experimental community health worker-delivered care coordination program for students with asthma within the context of the West Philadelphia Controls Asthma study. METHODS: Surveys (n = 256) and semi-structured interviews (n = 41) were completed with principals, teachers, nurses, and community health workers from 21 public and charter schools in West Philadelphia between January 2019 and September 2021. Survey participants completed the Evidence Based Practice Attitudes Scale, the Implementation Leadership Scale, and Organizational Climate Index. Semi-structured qualitative interview guides were developed, informed by the Consolidated Framework for Implementation Research. RESULTS: Participant responses indicate that they perceived benefits for schools and students related to the community health worker-based care coordination program. Several barriers and facilitators to implementing the program were noted, including challenges associated with incorporating the program into school nurse workflow, environmental triggers in the school environment, and challenges communicating with family members. An important facilitator that was identified was having supportive school administrators and staff who were engaged and saw the benefits of the program. CONCLUSIONS: This work can inform implementation planning for other locales interested in implementing community-based pediatric asthma control programs delivered by community health workers in schools.

Primary care provider confidence in addressing opioid use disorder: A concept analysis.

Primary care providers (PCPs) are well-positioned to provide care for opioid use disorder (OUD), yet very few address OUD regularly. One contributing factor may be PCPs' lack of confidence in their ability to effectively treat OUD. Evidence demonstrates that clinician confidence in home care and hospital settings is associated with improved care delivery and patient outcomes. However, a conceptual definition of PCP confidence in addressing OUD has yet to be established. The aim of this concept analysis is to enhance conceptual understanding of PCP confidence in addressing OUD and inform future measurement strategies. Following Walker and Avant's method of concept analysis, PubMed, PsycINFO, and Google Scholar were searched in October 2021. Manuscripts were included if they referenced confidence in relation to PCPs who provide care to adult patients with OUD. Studies conducted outside the US and not published in English were excluded. The search resulted in 18 studies which were synthesized to conceptualize PCP confidence in addressing OUD. Defining attributes include self-efficacy, experience, and readiness to address OUD. These attributes may be influenced by organizational culture, training, support, and resources. Consequences of PCP confidence addressing OUD may include improved patient outcomes, improved delivery of and access to OUD care, and PCP attitude changes. This concept analysis-which grounds the concept of PCP confidence in addressing OUD in the theoretical and empirical literature-lays the framework for future measurement of the concept. This represents a critical first step towards developing strategies to enhance PCP confidence in addressing OUD.

Improving Payment for Collaborative Mental Health Care in Primary Care.

BACKGROUND: There is strong evidence supporting implementation of the Collaborative Care Model within primary care. Fee-for-service payment codes, published by Current Procedural Terminology in 2018, have made collaborative care separately reimbursable for the first time. These codes (ie, 99492-99494) reimburse for time spent per month by any member of the care team engaged in Collaborative Care, including behavioral care managers, primary care providers, and consulting psychiatrists. Time-based billing for these codes presents challenges for providers delivering Collaborative Care services. OBJECTIVES: Based on experience from multiple health care organizations, we reflect on these challenges and provide suggestions for implementation and future refinement of the codes. CONCLUSIONS: Further refinements to the codes are encouraged, including moving from a calendar month to a 30-day reimbursement cycle. In addition, we recommend payers adopt the new code proposed by the Centers for Medicare and Medicaid Services to account for smaller increments of time.

Applying the Policy Ecology Framework to Philadelphia's Behavioral Health Transformation Efforts.

Raghavan et al. (Implement Sci 3(26):1-9, 2008) proposed that effective implementation of evidence-based practices requires implementation strategies deployed at multiple levels of the "policy ecology," including the organizational, regulatory or purchaser agency, political, and social levels. However, much of implementation research and practice targets providers without accounting for contextual factors that may influence provider behavior. This paper examines Philadelphia's efforts to work toward an evidence-based and recovery-oriented behavioral health system, and uses the policy ecology framework to illustrate how multifaceted, multilevel implementation strategies can facilitate the widespread implementation of evidence-based practices. Ongoing challenges and implications for research and practice are discussed.

Identifying Common and Unique Barriers and Facilitators to Implementing Evidence-Based Practices for Suicide Prevention across Primary Care and Specialty Mental Health Settings.

OBJECTIVE: We identified common and unique barriers and facilitators of evidence-based suicide prevention practices across primary care practices with integrated behavioral health services and specialty mental health settings to identify generalizable strategies for enhancing future implementation efforts. METHOD: Twenty-six clinicians and practice leaders from behavioral health (n = 2 programs) and primary care (n = 4 clinics) settings participated. Participation included a semi-structured qualitative interview on barriers and facilitators to implementing evidence-based suicide prevention practices. Within that interview, clinicians participated in a chart-stimulated recall exercise to gather additional information about decision making regarding suicide screening. Interview guides and qualitative coding were informed by leading frameworks in implementation science and behavioral science, and an integrated approach to interpreting qualitative results was used. RESULTS: There were a number of similar themes associated with implementation of suicide prevention practices across settings and clinician types, such as the benefits of inter-professional collaboration and uncertainties about managing suicidality once risk was disclosed. Clinicians also highlighted barriers unique to their settings. For primary care settings, time constraints and competing demands were consistently described as barriers. For specialty mental health settings, difficulties coordinating care with schools and other providers in the community made implementation of suicide prevention practices challenging. CONCLUSION: Findings can inform the development and testing of implementation strategies that are generalizable across primary care and specialty mental health settings, as well as those tailored for unique site needs, to enhance use of evidence-based suicide prevention practices in settings where individuals at risk for suicide are especially likely to present.HIGHLIGHTSWe examined barriers and facilitators to suicide prevention across health settings.Common and unique barriers and facilitators across health-care settings emerged.Findings can enhance suicide prevention implementation across health-care settings.

Adapting psychotherapy in collaborative care for treating opioid use disorder and co-occurring psychiatric conditions in primary care.

INTRODUCTION: Opioid use disorder (OUD) and psychiatric conditions commonly co-occur yet are infrequently treated with evidence-based therapeutic approaches, resulting in poor outcomes. These conditions, separately, present challenges to treatment initiation, retention, and success. These challenges are compounded when individuals have OUD and psychiatric conditions. METHOD: Recognizing the complex needs of these individuals, gaps in care, and the potential for primary care to bridge these gaps, we developed a psychotherapy program that integrates brief, evidence-based psychotherapies for substance use, depression, and anxiety, building on traditional elements of the Collaborative Care Model (CoCM). In this article, we describe this psychotherapy program in a primary care setting as part of a compendium of collaborative services. RESULTS: Patients receive up to 12 sessions of evidence-based psychotherapy and case management based on a structured treatment manual that guides treatment via Motivational Enhancement; Cognitive Behavioral Therapies for depression, anxiety, and/or substance use disorder; and/or Behavioral Activation components. DISCUSSION: Novel, integrated treatments are needed to advance service delivery for individuals with OUD and psychiatric conditions and these programs must be rigorously evaluated. We describe our team's efforts to test our psychotherapy program in a large primary care network as part of an ongoing three-arm randomized controlled trial.

Implementing evidence-based practices in nonspecialty mental health settings.

OBJECTIVE: Mental health services are often implemented in settings in which mental health is not the primary mission. Schools, primary care clinics, criminal justice and child welfare institutions, and senior centers have been increasingly adding mental health care to their compendium of services owing to the high rates of mental health needs in these settings. Despite numerous challenges to implementing mental health practices in settings where mental health care has not traditionally been a part of the service model, the demand for mental health services in these settings is growing. Implementation science offers a lens through which to understand unique challenges and potential solutions to implementing mental health services in these settings, with the ultimate goal of ensuring the implementation of evidence-based services. METHOD AND RESULTS: In this conceptual article, we discuss common overarching barriers to implementing evidence-based mental health interventions in nonspecialty mental health settings, such as workforce challenges, competing priorities, and financial considerations. Then, using examples from schools and primary care, we elucidate unique contextual considerations and implementation challenges in these settings. Finally, we articulate a research agenda for advancing implementation of evidence-based practices in nonspecialty mental health including highlighting promising implementation strategies (e.g., task shifting, adaptation) and the most relevant implementation outcomes to assess in these contexts (e.g., appropriateness, feasibility). CONCLUSIONS: Given that nonspecialty mental health settings deliver a large proportion of mental health care to traditionally underserved populations, there are important public health implications to advancing research in this area and ensuring implemented services are evidence-based.

Increasing access to mental health supports for healthcare workers during the COVID-19 pandemic and beyond through a novel coaching program.

The COVID-19 pandemic led to heightened anxiety, distress, and burnout among healthcare workers and faculty in academic medicine. Penn Medicine launched Coping First Aid (CFA) in March 2020 in response to the pandemic. Informed by Psychological First Aid principles and therapeutic micro skills, CFA was designed as a tele-mental healthcare service for health system employees and their families delivered by trained lay volunteer coaches under the supervision of licensed mental health clinicians. We present an overview of the model, feasibility and utilization data, and preliminary implementation and effectiveness outcomes based on cross sectional coach (n = 22) and client (n = 57) self-report surveys with a subset of program users in the first year. A total of 44 individuals completed training and were certified to coach. Over the first 24 months of the program, 513 sessions occurred with 273 clients (119 sessions were no-shows or canceled). Follow-up appointments were recommended in 52.6% (n = 270) of sessions and 21.2% (n = 109) of clients were referred for professional mental health care. Client survey respondents reported CFA was helpful; 60% were very or extremely satisfied, and 74% indicated they would recommend the program. Our preliminary findings suggest that CFA was feasible to implement and most clients found the service beneficial. CFA provides a model for rapidly developing and scaling mental health supports during and beyond the pandemic.

Leveraging behavioral economics and implementation science to engage patients at risk for suicide in mental health treatment: a pilot study protocol.

BACKGROUND: Primary care is an ideal setting to connect individuals at risk for suicide to follow-up care; however, only half of the patients referred from the primary care attend an initial mental health visit. We aim to develop acceptable, feasible, low-cost, and effective new strategies to increase treatment initiation among at-risk individuals identified in primary care. METHODS: We will conduct a multi-phase, mixed-methods study. First, we will conduct a chart review study by using administrative data, including medical records, to identify characteristics of primary care patients at risk for suicide who do or do not attend an initial mental health visit following a referral. Second, we will conduct a mixed methods study by using direct observations and qualitative interviews with key stakeholders (N = 65) to understand barriers and facilitators to mental health service initiation among at-risk individuals. Stakeholders will include patients with suicidal ideation referred from primary care who do and do not attend a first mental health visit, primary care and behavioral health providers, and individuals involved in the referral process. We also will collect preliminary self-report and behavioral data regarding potential mechanisms of behavior change (i.e., self-regulation and social support) from patients. Third, we will leverage these findings, relevant frameworks, and the extant literature to conduct a multi-arm, non-randomized feasibility trial. During this trial, we will rapidly prototype and test strategies to support attendance at initial mental health visits. Strategies will be developed with subject matter experts (N = 10) and iteratively pilot tested (~5 patients per strategy) and refined. Research will be completed in the Penn Integrated Care Program (PIC), which includes fourteen primary care clinics in Philadelphia that provide infrastructure for electronic referrals, patient communication, and data access. DISCUSSION: We will leverage frameworks and methods from behavioral economics and implementation science to develop strategies to increase mental health treatment initiation among individuals at risk for suicide identified in primary care. This project will lead to an evaluation of these strategies in a fully powered randomized trial and contribute to improvements in access to and engagement in mental health services for individuals at risk for suicide.

Metrics to evaluate implementation scientists in the USA: what matters most?

BACKGROUND: Implementation science has grown rapidly as a discipline over the past two decades. An examination of how publication patterns and other scholarly activities of implementation scientists are weighted in the tenure and promotion process is needed given the unique and applied focus of the field. METHODS: We surveyed implementation scientists (mostly from the USA) to understand their perspectives on the following matters: (1) factors weighted in tenure and promotion for implementation scientists, (2) how important these factors are for success as an implementation scientist, (3) how impact is defined for implementation scientists, (4) top journals in implementation science, and (5) how these journals are perceived with regard to their prestige. We calculated univariate descriptive statistics for all quantitative data, and we used Wilcoxon signed-rank tests to compare the participants' ratings of various factors. We analyzed open-ended qualitative responses using content analysis. RESULTS: One hundred thirty-two implementation scientists completed the survey (response rate = 28.9%). Four factors were rated as more important for tenure and promotion decisions: number of publications, quality of publication outlets, success in obtaining external funding, and record of excellence in teaching. Six factors were rated as more important for overall success as an implementation scientist: presentations at professional meetings, involvement in professional service, impact of the implementation scientist's scholarship on the local community and/or state, impact of the implementation scientist's scholarship on the research community, the number and quality of the implementation scientist's community partnerships, and the implementation scientist's ability to disseminate their work to non-research audiences. Participants most frequently defined and described impact as changing practice and/or policy. This expert cohort identified Implementation Science as the top journal in the field. CONCLUSIONS: Overall, there was a significant mismatch between the factors experts identified as being important to academic success (e.g., tenure and promotion) and the factors needed to be a successful implementation scientist. Findings have important implications for capacity building, although they are largely reflective of the promotion and tenure process in the USA.

Characteristics of Patients Who Attended Behavioral Health Services After Primary Care Referral With Referral Management Support.

OBJECTIVE: This study examined whether documented disparities in access to behavioral health specialty care persisted in a novel integrated primary care model situated in a large health system when triage and referral management supports were provided by a centralized resource center for patients with behavioral health needs. METHODS: Patients triaged and referred to specialty behavioral health care who did or did not attend a specialty care visit (N=1,450) were compared in terms of various demographic and clinical characteristics by using binary logistic regression. RESULTS: Among patients with attendance data, financially unstable individuals were more likely than financially stable counterparts to miss their first appointment with a specialty behavioral health provider after referral from primary care. Previously documented attendance disparities based on race, ethnicity, and illness severity were not observed. CONCLUSIONS: These findings can inform targeted strategies to increase attendance among patients with financial insecurity and reduce disparities in outpatient behavioral health services.

Measurement of unnecessary psychiatric readmissions in the context of care transition interventions: a scoping review.

OBJECTIVE: The objective of this study was to examine how published studies of inpatient to outpatient mental healthcare transition processes have approached measuring unnecessary psychiatric readmissions. DESIGN: Scoping review using Levac et al's enhancement to Arksey and O'Malley's framework for conducting scoping reviews. DATA SOURCES: Medline (Ovid), Embase (Ovid), PsycINFO, CINAHL, Cochrane and ISI Web of Science article databases were searched from 1 January 2009 through 28 February 2019. ELIGIBILITY CRITERIA FOR SELECTING STUDIES: We included studies that (1) are about care transition processes associated with unnecessary psychiatric readmissions and (2) specify use of at least one readmission time interval (ie, the time period since previous discharge from inpatient care, within which a hospitalisation can be considered a readmission). DATA EXTRACTION AND SYNTHESIS: We assessed review findings through tabular and content analyses of the data extracted from included articles. RESULTS: Our database search yielded 3478 unique articles, 67 of which were included in our scoping review. The included articles varied widely in their reported readmission time intervals used. They provided limited details regarding which readmissions they considered unnecessary and which risks they accounted for in their measurement. There were no perceptible trends in associations between the variation in these findings and the included studies' characteristics (eg, target population, type of care transition intervention). CONCLUSIONS: The limited specification with which studies report their approach to unnecessary psychiatric readmissions measurement is a noteworthy gap identified by this scoping review, and one that can hinder both the replicability of conducted studies and adaptations of study methods by future investigations. Recommendations stemming from this review include (1) establishing a framework for reporting the measurement approach, (2) devising enhanced guidelines regarding which approaches to use in which circumstances and (3) examining how sensitive research findings are to the choice of the approach.

Strategic Implementation Planning for Integrated Behavioral Health Services in Pediatric Primary Care.

BACKGROUND: Delivering physical and behavioral health services in a single setting is associated with improved quality of care and reduced health care costs. Few health systems implementing integrated care develop conceptual models and targeted measurement strategies a priori with an eye toward adoption, implementation, sustainment, and evaluation. This is a broad challenge in the field, which can make it difficult to disentangle why implementation is or is not successful. METHOD: This paper discusses strategic implementation and evaluation planning for a pediatric integrated care program in a large health system. Our team developed a logic model, which defines resources and community characteristics, program components, evaluation activities, short-term activities, and intermediate and anticipated long-term patient-, clinician-, and practice-related outcomes. The model was designed based on research and stakeholder input to support strategic implementation and evaluation of the program. For each aspect of the logic model, a measurement battery was selected. Initial implementation data and intermediate outcomes from a pilot in five practices in a 30-practice pediatric primary care network are presented to illustrate how the logic model and evaluation plan have been used to guide the iterative process of program development. RESULTS: A total of 4,619 office visits were completed during the two years of the pilot. Primary care clinicians were highly satisfied with the integrated primary care program and provided feedback on ways to further improve the program. Members of the primary care team and behavioral health providers rated the program as being relatively well integrated into the practices after the second year of the pilot. CONCLUSIONS: This logic model and evaluation plan provide a template for future projects integrating behavioral health services in non-specialty mental health settings, including pediatric primary care, and can be used broadly to provide structure to implementation and evaluation activities and promote replication of effective initiatives.

Adapting Safety Check as a Universal Suicide Prevention Strategy in Pediatric Primary Care.

OBJECTIVE: The presence of unlocked firearms in the home is associated with increased risk of suicide and unintentional injury in youth. We adapted an evidence-based program for promoting safe firearm storage, Safety Check, to enhance its acceptability as a universal suicide prevention strategy in pediatric primary care. METHODS: We applied ADAPT-ITT, an established adaptation framework, to guide iterative program adaptation with ongoing input from key stakeholders. The present study describes 2 phases of ADAPT-ITT: the Production phase (generating adaptations) and the Topical Experts phase (gathering stakeholder feedback on adaptations). After generating proposed program adaptations based on 3 inputs (stakeholder feedback collected in a prior study, the behavioral science literature, and best practices in pediatric medicine), we elicited feedback from stakeholders with firearm expertise. The adaptations included changes such as clarifying firearm ownership will not be documented in the medical record and offering follow-up reminders. We also crowdsourced feedback from 337 parents to select a new name and program logo. RESULTS: Saturation was reached with 9 stakeholders. Feedback confirmed the value of adaptations that: 1) considered context (eg, reason for ownership), 2) promoted parent autonomy in decision-making, and 3) ensured privacy. The most preferred program name was Suicide and Accident prevention through Family Education (SAFE) Firearm. CONCLUSIONS: Guided by an established adaptation framework that prioritized multistage stakeholder feedback, adaptations to the original Safety Check were deemed acceptable. We plan to test the SAFE Firearm program as a universal suicide prevention strategy in pediatric primary care via a hybrid effectiveness-implementation trial.

Implementing nudges for suicide prevention in real-world environments: project INSPIRE study protocol.

BACKGROUND: Suicide is a global health issue. There are a number of evidence-based practices for suicide screening, assessment, and intervention that are not routinely deployed in usual care settings. The goal of this study is to develop and test implementation strategies to facilitate evidence-based suicide screening, assessment, and intervention in two settings where individuals at risk for suicide are especially likely to present: primary care and specialty mental health care. We will leverage methods from behavioral economics, which involves understanding the many factors that influence human decision making, to inform strategy development. METHODS: We will identify key mechanisms that limit implementation of evidence-based suicide screening, assessment, and intervention practices in primary care and specialty mental health through contextual inquiry involving behavioral health and primary care clinicians. Second, we will use contextual inquiry results to systematically design a menu of behavioral economics-informed implementation strategies that cut across settings, in collaboration with an advisory board composed of key stakeholders (i.e., behavioral economists, clinicians, implementation scientists, and suicide prevention experts). Finally, we will conduct rapid-cycle trials to test and refine the menu of implementation strategies. Primary outcomes include clinician-reported feasibility and acceptability of the implementation strategies. DISCUSSION: Findings will elucidate ways to address common and unique barriers to evidence-based suicide screening, assessment, and intervention practices in primary care and specialty mental health care. Results will yield refined, pragmatically tested strategies that can inform larger confirmatory trials to combat the growing public health crisis of suicide.

Pilot Study for the Fidelity, Acceptability and Effectiveness of a PBIS Program plus Mental Health Supports in Under-resourced Urban Schools.

This paper describes implementation (fidelity, perceived acceptability) and tier 1 and tier 2 outcomes of a school-wide positive behavior interventions and supports approach (PBIS) including mental health supports at tier 2 in two K-8 urban schools. Interventions for tier 2 consisted of three manualized group cognitive behavioral therapy (GCBT) protocols for externalizing behavior problems, depression and anxiety. tier 1 and tier 2 interventions were implemented with fidelity but program feasibility for tier 2 was in question because school personnel needed a great deal of external support in order to implement the interventions. tier 1 interventions were associated with a decrease in office discipline referrals. Students participating in GCBT showed a significant decrease in mental health diagnostic severity at post-treatment. A discussion of perceived and actual implementation barriers and how they were addressed is provided. Implications for practice in low-income urban schools are discussed.

The implementation of a team training intervention for school mental health: Lessons learned.

Children obtain more mental health services through schools than through any other system. In urban, low-resource schools, mental health care often is provided by teams of contracted community mental health workers. Implementation of intended services may struggle in the context of challenges related to team functioning. Team Strategies and Tools to Enhance Performance and Patient Safety (TeamSTEPPS) is an efficacious approach for improving team functioning in health care. In collaboration with stakeholders, we adapted TeamSTEPPS for school mental health teams and pilot-tested it in 3 schools participating in an ongoing implementation of cognitive-behavioral therapy. In total, 3 teams randomized to receive TeamSTEPPS were compared with 3 teams who did not participate in TeamSTEPPS. Feasibility and acceptability of the adapted TeamSTEPPS and the impact on team skills and behavior were assessed through qualitative interviews and field notes and quantitatively over the course of 1 school year. In this article, we describe the process of adapting and implementing TeamSTEPPS. In addition to providing the researchers' perspective, we illustrate participant perspectives using qualitative data when possible. Key challenges included leader and staff turnover, logistical barriers (e.g., difficulty securing private space for qualitative interviews in schools), and navigating the protection of participant rights and autonomy given that prospective participants were employed by an agency with a vested interest in their participation. Concrete suggestions for overcoming challenges are provided to guide future research. (PsycINFO Database Record (c) 2019 APA, all rights reserved).

Predictors of clinician use of exposure therapy in community mental health settings.

Exposure therapy is recognized as the key component of cognitive-behavioral treatment for anxiety. However, exposure is the least used evidence-based treatment in community mental health settings and is the most challenging technique for clinicians to adopt within the context of effectiveness and implementation trials. Little work has examined clinician and organizational characteristics that predict use of exposure, which is important for identifying implementation strategies that may increase its use. In a large sample of community health clinicians (N=335) across 31 clinical practice sites, this study characterized clinician and organizational predictors of exposure use and relaxation for anxiety. Mixed effects regression analyses indicated that both clinician attitudes and an organization's implementation climate may be important levers for interventions seeking to increase clinician exposure use. Greater clinician use of relaxation strategies was also associated with less exposure use. Results point to important implications for implementing cognitive-behavioral therapy for anxiety, including de-emphasizing relaxation and attending to organizational climate.

The relationship between consumer, clinician, and organizational characteristics and use of evidence-based and non-evidence-based therapy strategies in a public mental health system.

We investigated the relationship between consumer, clinician, and organizational factors and clinician use of therapy strategies within a system-wide effort to increase the use of cognitive-behavioral therapy. Data from 247 clinicians in 28 child-serving organizations were collected. Clinicians participating in evidence-based practice training initiatives were more likely to report using cognitive-behavioral therapy when they endorsed more clinical experience, being salaried clinicians, and more openness to evidence-based practice. Clinicians participating in evidence-based practice initiatives were more likely to use psychodynamic techniques when they had older clients, less knowledge about evidence-based practice, more divergent attitudes toward EBP, higher financial strain, and worked in larger organizations. In clinicians not participating in evidence-based training initiatives; depersonalization was associated with higher use of cognitive-behavioral; whereas clinicians with less knowledge of evidence-based practices were more likely to use psychodynamic techniques. This study suggests that clinician characteristics are important when implementing evidence-based practices; and that consumer, clinician, and organizational characteristics are important when de-implementing non evidence-based practices. This work posits potential characteristics at multiple levels to target with implementation and deimplementation strategies.
