Using implementation science to evaluate a population-wide genomic screening program: Findings from the first 20,000 In Our DNA SC participants.

We use the implementation science framework RE-AIM (reach, effectiveness, adoption, implementation, and maintenance) to describe outcomes of In Our DNA SC, a population-wide genomic screening (PWGS) program. In Our DNA SC involves participation through clinical appointments, community events, or at home collection. Participants provide a saliva sample that is sequenced by Helix, and those with a pathogenic variant or likely pathogenic variant for CDC Tier 1 conditions are offered free genetic counseling. We assessed key outcomes among the first cohort of individuals recruited. Over 14 months, 20,478 participants enrolled, and 14,053 samples were collected. The majority selected at-home sample collection followed by clinical sample collection and collection at community events. Participants were predominately female, White (self-identified), non-Hispanic, and between the ages of 40-49. Participants enrolled through community events were the most racially diverse and the youngest. Half of those enrolled completed the program. We identified 137 individuals with pathogenic or likely pathogenic variants for CDC Tier 1 conditions. The majority (77.4%) agreed to genetic counseling, and of those that agreed, 80.2% completed counseling. Twelve clinics participated, and we conducted 108 collection events. Participants enrolled at home were most likely to return their sample for sequencing. Through this evaluation, we identified facilitators and barriers to implementation of our state-wide PWGS program. Standardized reporting using implementation science frameworks can help generalize strategies and improve the impact of PWGS.

A Systematic Review of Implementation Research on Determinants and Strategies of Effective HIV Interventions for Men Who Have Sex with Men in the United States.

Men who have sex with men (MSM) are disproportionately affected by HIV, accounting for two-thirds of HIV cases in the United States despite representing ∼5% of the adult population. Delivery and use of existing and highly effective HIV prevention and treatment strategies remain suboptimal among MSM. To summarize the state of the science, we systematically review implementation determinants and strategies of HIV-related health interventions using implementation science frameworks. Research on implementation barriers has focused predominantly on characteristics of individual recipients (e.g., ethnicity, age, drug use) and less so on deliverers (e.g., nurses, physicians), with little focus on system-level factors. Similarly, most strategies target recipients to influence their uptake and adherence, rather than improving and supporting implementation systems. HIV implementation research is burgeoning; future research is needed to broaden the examination of barriers at the provider and system levels, as well as expand knowledge on how to match strategies to barriers-particularly to address stigma. Collaboration and coordination among federal, state, and local public health agencies; community-based organizations; health care providers; and scientists are important for successful implementation of HIV-related health innovations.

Leveraging Implementation Science to Advance Environmental Justice Research and Achieve Health Equity through Neighborhood and Policy Interventions.

Environmental justice research is increasingly focused on community-engaged, participatory investigations that test interventions to improve health. Such research is primed for the use of implementation science-informed approaches to optimize the uptake and use of interventions proven to be effective. This review identifies synergies between implementation science and environmental justice with the goal of advancing both disciplines. Specifically, the article synthesizes the literature on neighborhood-, community-, and policy-level interventions in environmental health that address underlying structural determinants (e.g., structural racism) and social determinants of health. Opportunities to facilitate and scale the equitable implementation of evidence-based environmental health interventions are highlighted, using urban greening as an illustrative example. An environmental justice-focused version of the implementation science subway is provided, which highlights these principles: Remember and Reflect, Restore and Reclaim, and Reinvest. The review concludes with existing gaps and future directions to advance the science of implementation to promote environmental justice.

Bridges and Mechanisms: Integrating Systems Science Thinking into Implementation Research.

We present a detailed argument for how to integrate, or bridge, systems science thinking and methods with implementation science. We start by showing how fundamental systems science principles of structure, dynamics, information, and utility are relevant for implementation science. Then we examine the need for implementation science to develop and apply richer theories of complex systems. This can be accomplished by emphasizing a causal mechanisms approach. Identifying causal mechanisms focuses on the "cogs and gears" of public health, clinical, and organizational interventions. A mechanisms approach focuses on how a specific strategy will produce the implementation outcome. We show how connecting systems science to implementation science opens new opportunities for examining and addressing social determinants of health and conducting equitable and ethical implementation research. Finally, we present case studies illustrating successful applications of systems science within implementation science in community health policy, tobacco control, health care access, and breast cancer screening.

Advancing the Science and Application of Implementation Science to Promote Health Equity: Commentary on the Symposium.

There has been an increasing focus on making health equity a more explicit and foundational aspect of the research being conducted in public health and implementation science. This commentary provides an overview of five reviews in this Annual Review of Public Health symposium on Implementation Science and Health Equity. These articles reflect on and advance the application of core implementation science principles and concepts, with a focus on promoting health equity across a diverse range of public health and health care settings. Taken together, the symposium articles highlight critical conceptual, methodological, and empirical advances in the study designs, frameworks, and approaches that can help address equity considerations in the use of implementation science in both domestic and global contexts. Finally, this commentary highlights how work featured in this symposium can help inform future directions for rapidly taking public health to scale, particularly among systemically marginalized populations and communities.

Optimising the implementation of evidence-based osteoarthritis guidelines in primary care: Development of a Knowledge Mobilisation Toolkit.

OBJECTIVE: Implementing clinical guidelines for osteoarthritis (OA) in primary care is complex. Whilst international guidelines detail what best practice for OA looks like, little is known about how this is best implemented. Limited resources are available to guideline developers, practitioners, researchers, or the public to facilitate implementation. Set in the context of a larger research project which sought to understand the factors that influence knowledge mobilisation (KM) in implementation for OA guidelines, this study reports the development of a toolkit to optimise KM for the implementation of evidence-based OA guidelines in primary care. DESIGN: Triangulation of three qualitative data sets was conducted, followed by a stakeholder consensus exercise. Public contributors were involved in dedicated meetings (n = 3) to inform the content, design, and KM plans for the toolkit. RESULTS: From data triangulation, 53 key findings were identified, which were refined into 30 draft recommendation statements, within six domains: approaches to KM; the knowledge mobiliser role; understanding context; implementation planning; the nature of the intervention; and appealing to a range of priorities. Stakeholder voting (n = 27) demonstrated consensus with the recommendations and informed the wording of the final toolkit. CONCLUSIONS: Factors that optimise KM for OA guideline implementation in primary care were identified. Empirical data, practice-based evidence, implementation practice, and stakeholder (including patient and public) engagement have informed a toolkit comprising several overarching principles of KM, which are suitable for use in primary care. Consideration of equitable access when implementing evidence-based OA care among diverse populations is recommended when using the toolkit. Further research is needed to evaluate the toolkit's utility and transferability.

Establishing consensus recommendations for long-term osteoporosis care for patients who have attended an Australian fracture liaison service: a Delphi study.

Coordinating healthcare activities between fracture liaison services (FLS) and primary care is challenging. Using a Delphi technique, we developed 34 consensus statements to support improved care coordination across this healthcare transition. PURPOSE: Evidence supporting an optimal coordination strategy between fracture liaison services (FLS) and primary care is lacking. This study aimed to develop consensus statements to support consistency and benchmarking of clinical practice to improve coordination of care for patients transitioning from FLS to primary care following an osteoporotic fracture. METHODS: A Delphi technique was used to develop consensus among a panel of experts, including FLS clinicians (medical and non-medical), general practitioners (GPs), and consumers. RESULTS: Results of a preparatory questionnaire (n = 33) informed the development of 34 statements for review by expert panellists over two Delphi rounds (n = 25 and n = 19, respectively). The majority of participants were from New South Wales (82%), employed as FLS clinicians (78.8%) and working in metropolitan centres (60.6%). Consensus was achieved for 24/34 statements in round one and 8/10 statements in round two. All statements concerning patient education, communication, and the GP-patient relationship achieved consensus. Expert opinions diverged in some areas of clinician roles and responsibilities and long-term monitoring and management recommendations. CONCLUSION: We found clear consensus among experts in many key areas of FLS integration with primary care. While experts agreed that primary care is the most appropriate setting for long-term osteoporosis care, overall confidence in primary care systems to achieve this was low. The role of (and responsibility for) adherence monitoring in a resource-limited setting remains to be defined.

STRIKE-HBV: establishing an HBV screening programme in Kilifi, Kenya-challenges, successes and lessons learnt.

OBJECTIVES: Chronic hepatitis B infection affects 65 million people in the WHO African Region, but only 4.2% of these are diagnosed and 0.2% on treatment. Here, we present a short report describing establishment of a hepatitis B virus (HBV) programme in Kenya. We share experiences, successes and challenges to support development of future programmes. METHODS: From March 2023, we began the 'STRIKE-HBV' Study to identify people living with HBV (PLWHB) in Kilifi, Kenya. We employed local staff and provided education and training. Individuals were identified through three routes: (1) we offered free-of-charge HBV testing for all non-pregnant adults attending Kilifi Country Hospital (KCH) outpatient department; (2) we invited PLWHB to reattend for review; and (3) we invited close contacts of PLWHB for screening and vaccination if HBV was negative. All those seropositive for HBV were offered a comprehensive liver health assessment. RESULTS: We have established a framework for HBV screening, assessment and linkage to care in Kilifi. Between March 2023 and March 2024, we collected data for 80 PLWHB, comprising (1) screening of 1862 people of whom 30 were seropositive, (2) enrolment of 38 people known to be living with HBV and (3) testing of 97 close contacts of PLWHB, of whom 12 were positive. Among a limited subset with elastography data, we identified 9 of 59 as having significant fibrosis, and a further 6 people had laboratory aspartate transaminase (AST) to platelet ratio index (APRI) scores in keeping with fibrosis. We encountered challenges including procurement delays for hepatitis B surface antigen testing kits and HBV vaccinations, and issues accessing liver elastography. CONCLUSIONS: HBV screening was well received by the Kilifi population, has identified people at risk of liver disease progression and is improving linkage to care and vaccination at KCH. Future HBV programmes in WHO Africa can build on this experience as we work to develop accessible, affordable and acceptable care pathways.

Standards for the development and methodology of the 2023 IWGDF guidelines.

AIMS: Diabetes-related foot disease is a major source of patient burden and societal costs. Investing in evidence-based international guidelines on diabetes-related foot disease is important to reduce this burden and costs, provided the guidelines are focused on outcomes important to key stakeholders and are evidence-based and properly implemented. MATERIALS AND METHODS: The International Working Group on the Diabetic Foot (IWGDF) has published and updated international guidelines since 1999. The 2023 updates were made using the Grading of Recommendations Assessment Development and Evaluation evidence-to-decision framework. This concerns formulating relevant clinical questions and important outcomes, conducting systematic reviews of the literature and meta-analyses where appropriate, completing summary of judgement tables, and writing recommendations that are specific, unambiguous and actionable, along with their transparent rationale. RESULTS: We herein describe the development of the 2023 IWGDF Guidelines on the prevention and management of diabetes-related foot disease, which consists of seven chapters, each prepared by a separate working group of international experts. These chapters provide guidelines related to diabetes-related foot disease on prevention; classification of diabetes-related foot ulcer, offloading, peripheral artery disease, infection, wound healing interventions, and active Charcot neuro-osteoarthropathy. Based on these seven guidelines, the IWGDF Editorial Board also produced a set of practical guidelines. Each guideline underwent extensive review by the members of the IWGDF Editorial Board as well as independent international experts in each field. CONCLUSIONS: We believe that the adoption and implementation of the 2023 IWGDF guidelines by healthcare providers, public health agencies, and policymakers will improve the prevention and management of diabetes-related foot disease, and subsequently reduce the worldwide patient and societal burden caused by this disease.

Practical guidelines on the prevention and management of diabetes-related foot disease (IWGDF 2023 update).

Diabetes-related foot disease results in a major global burden for patients and the healthcare system. The International Working Group on the Diabetic Foot (IWGDF) has been producing evidence-based guidelines on the prevention and management of diabetes-related foot disease since 1999. In 2023, all IWGDF Guidelines have been updated based on systematic reviews of the literature and formulation of recommendations by multidisciplinary experts from all over the world. In addition, a new guideline on acute Charcot neuro-osteoarthropathy was created. In this document, the IWGDF Practical Guidelines, we describe the basic principles of prevention, classification and management of diabetes-related foot disease based on the seven IWGDF Guidelines. We also describe the organisational levels to successfully prevent and treat diabetes-related foot disease according to these principles and provide addenda to assist with foot screening. The information in these practical guidelines is aimed at the global community of healthcare professionals who are involved in the care of persons with diabetes. Many studies around the world support our belief that implementing these prevention and management principles is associated with a decrease in the frequency of diabetes-related lower-extremity amputations. The burden of foot disease and amputations is increasing at a rapid rate, and comparatively more so in middle to lower income countries. These guidelines also assist in defining standards of prevention and care in these countries. In conclusion, we hope that these updated practical guidelines continue to serve as a reference document to aid healthcare providers in reducing the global burden of diabetes-related foot disease.

Implementation of Food is Medicine Programs in Healthcare Settings: A Narrative Review.

Food is Medicine (FIM) programs to improve the accessibility of fruits and vegetables (FVs) or other healthy foods among patients with low income and diet-related chronic diseases are promising to improve food and nutrition security in the United States (US). However, FIM programs are relatively new and implementation guidance for healthcare settings using an implementation science lens is lacking. We used a narrative review to describe the evidence base on barriers and facilitators to FIM program integration in US healthcare settings following the Exploration, Preparation, Implementation, and Sustainment (EPIS) Framework. Evidence surrounding the EPIS Inner Context was a focus, including constructs Leadership, Organizational Characteristics, Quality and Fidelity Monitoring and Support, Organizational Staffing Processes, and Individual Characteristics. Peer-reviewed and grey literature about barriers and facilitators to FIM programs were of interest, defined as programs that screen and refer eligible patients with diet-related chronic disease experiencing food insecurity to healthy, unprepared foods. Thirty-one sources were included in the narrative review, including 22 peer-reviewed articles, four reports, four toolkits, and one thesis. Twenty-eight sources (90%) described EPIS Inner Context facilitators and 26 sources (84%) described FIM program barriers. The most common barriers and facilitators to FIM programs were regarding Quality and Fidelity Monitoring and Support (e.g., use of electronic medical records for tracking and evaluation, strategies to support implementation) and Organizational Staffing Processes (e.g., clear delineation of staff roles and capacity); although, barriers and facilitators to FIM programs were identified among all EPIS Inner Context constructs. We synthesized barriers and facilitators to create an EPIS-informed implementation checklist for healthcare settings for use among healthcare organizations/providers, partner organizations, and technical assistance personnel. We discuss future directions to align FIM efforts with implementation science terminology and theories, models, and frameworks to improve the implementation evidence base and support FIM researchers and practitioners.

User-Centered Design of a Preference-Driven Patient Activation Tool for Optimizing Depression Treatment in Integrated Primary Care Settings (The Transform DepCare Study).

BACKGROUND: Few patient engagement tools incorporate the complex patient experiences, contexts, and workflows that limit depression treatment implementation. OBJECTIVE: Describe a user-centered design (UCD) process for operationalizing a preference-driven patient activation tool. DESIGN: Informed by UCD and behavior change/implementation science principles, we designed a preference-driven patient activation prototype for engaging patients in depression treatment. We conducted three usability cycles using different recruitment/implementation approaches: near live/live testing in primary care waiting rooms (V1-2) and lab-based think aloud testing (V3) oversampling older, low-literacy, and Spanish-speaking patients in the community and via EHR algorithms. We elicited clinician and "heuristic" expert input. MAIN MEASURES: We administered the system usability scale (SUS) all three cycles and pre-post V3, the patient activation measure, decisional conflict scale, and depression treatment barriers. We employed descriptive statistics and thematically analyzed observer notes and transcripts for usability constructs. RESULTS: Overall, 43 patients, 3 clinicians, and 5 heuristic (a usability engineering method for identifying usability problems) experts participated. Among patients, 41.9% were ≥ 65 years old, 79.1% female, 23.3% Black, 62.8% Hispanic, and 55.8% Spanish-speaking and 46.5% had ≤ high school education. We described V1-3 usability (67.2, 77.3, 81.8), treatment seeking (92.3%, 87.5%, 92.9%), likelihood/comfort discussing with clinician (76.9%, 87.5%, 100.0%), and pre vs. post decisional conflict (23.7 vs. 15.2), treatment awareness (71.4% vs. 92.9%), interest in antidepressants (7.1% vs. 14.3%), and patient activation (66.8 vs. 70.9), with fewer barriers pertaining to cost/insurance, access/coordination, and self-efficacy/stigma/treatment efficacy. Key themes included digital literacy, understandability, high acceptability for aesthetics, high usefulness of patient/clinician videos, and workflow limitations. We adapted manual entry/visibility/content; added patient activation and a personalized algorithm; and proposed flexible, care manager delivery leveraging clinic screening protocols. DISCUSSION: We provide an example of leveraging UCD to design/adapt a real-world, patient experience and workflow-aligned patient activation tool in diverse populations.

Transferability of the NHS low-calorie diet programme: A qualitative exploration of factors influencing the programme's transfer ahead of wide-scale adoption.

INTRODUCTION: Although behavioural interventions have been found to help control type 2 diabetes (T2D), it is important to understand how the delivery context can influence implementation and outcomes. The NHS committed to testing a low-calorie diet (LCD) programme designed to support people living with excess weight and T2D to lose weight and improve diabetes outcomes. Understanding what influenced implementation during the programme pilot is important in optimising rollout. This study explored the transferability of the NHS LCD Programme prior to wider adoption. METHODS: Twenty-five interviews were undertaken with stakeholders involved in implementing the LCD programme in pilot sites (health service leads, referring health professionals and programme deliverers). Interviews with programme participants (people living with T2D) were undertaken within a larger programme of work, exploring what worked, for whom and why, which is reported separately. The conceptual Population-Intervention-Environment-Transfer Model of Transferability (PIET-T) guided study design and data collection. Constructs of the model were also used as a deductive coding frame during data analysis. Key themes were identified which informed recommendations to optimise programme transfer. RESULTS: Population: Referral strategies in some areas lacked consideration of population characteristics. Many believed that offering a choice of delivery model would promote acceptability and accessibility of the eligible population. INTERVENTION: Overall, stakeholders had confidence in the LCD programme due to the robust evidence base along with anecdotal evidence, but some felt the complex referral process hindered engagement from GP practices. ENVIRONMENT: Stakeholders described barriers to accessing the programme, including language and learning difficulties. Transferability: Multidisciplinary working and effective communication supported successful implementation. CONCLUSION: Referral strategies to reach underrepresented groups should be considered during programme transfer, along with timely data from service providers on access and programme benefits. A choice of delivery models may optimise uptake. Knowledge sharing between sites on good working practices is encouraged, including increasing engagement with key stakeholders.

Leveling Up PrEP: Implementation Strategies at System and Structural Levels to Expand PrEP Use in the United States.

PURPOSE OF REVIEW: Despite highly effective biomedical HIV pre-exposure prophylaxis (PrEP) options, suboptimal PrEP uptake impedes progress towards ending the epidemic in the United States of America (USA). Implementation science bridges what we know works in controlled clinical trial settings to the context and environment in which efficacious tools are intended to be deployed. In this review, we focus on strategies that target PrEP use barriers at the system or structural level, exploring the implications and opportunities in the context of the fragmented USA healthcare system. RECENT FINDINGS: Task shifting could increase PrEP prescribers, but effectiveness evidence is scarce in the USA, and generally focused in urban settings. Integration of PrEP within existing healthcare infrastructure concentrates related resources, but demonstration projects rarely present the resource implications of redirecting staff. Changing the site of service via expanded telehealth could improve access to more rural populations, though internet connectivity, technology access, and challenges associated with determining biomedical eligibility remain logistical barriers for some of the highest burden communities in the USA. Finally, a tailored care navigation and coordination approach has emerged as a highly effective component of PrEP service provision, attempting to directly modify the system-level determinants of PrEP use experienced by the individual. We highlight recent advances and evidence surrounding task shifting, integration, service delivery, and tailoring. With the exception of tailored care navigation, evidence is mixed, and the downstream impact and sustainability of task shifting and care integration require further attention. To maximize PrEP outcomes, research will need to continue to examine the interplay between individuals, clinics, and the healthcare system and associated policies within which they operate.

"Your Package Could Not Be Delivered": The State of Digital HIV Intervention Implementation in the US.

PURPOSE OF REVIEW: Despite continuous innovations and federal investment to create digital interventions addressing the HIV prevention and care continua, these interventions have not reached people in the U.S. at scale. This article reviews what is known about U.S. implementation of digital HIV interventions and presents a strategy to cross the research-to-practice chasm for these types of interventions. RECENT FINDINGS: We conducted a narrative review of U.S.-based original research on implementation of digital HIV interventions and identified few studies reporting on implementation determinants, strategies, processes, or outcomes, particularly outside the context of effectiveness trials. To supplement the literature, in 2023, we surveyed 47 investigators representing 64 unique interventions about their experiences with implementation after their research trials. Respondents placed high importance on intervention implementation, but major barriers included lack of funding and clear implementation models, technology costs, and difficulty identifying partners equipped to deliver digital interventions. They felt that responsibility for implementation should be shared between intervention developers, deliverers (e.g., clinics), and a government entity. If an implementation center were to exist, most respondents wanted to be available for guidance or technical assistance but largely wanted less involvement. Numerous evidence-based, effective digital interventions exist to address HIV prevention and care. However, they remain "on the shelf" absent a concrete and sustainable model for real-world dissemination and implementation. Based on our findings, we call for the creation of national implementation centers, analogous to those in other health systems, to facilitate digital HIV intervention delivery and accelerate progress toward ending the U.S. epidemic.

Development, implementation and impact of an immunoglobulin stewardship programme in Saskatchewan, Canada.

BACKGROUND AND OBJECTIVES: Intravenous immunoglobulin (IVIG) is one of the most costly and limited-supply blood products. Judicious use of this therapy is important to ensure a continued supply is available for patients in need. The Saskatchewan IG Stewardship Program was initiated to monitor and reduce inappropriate IG use. MATERIALS AND METHODS: The Program was developed and implemented through the collaborative efforts of a multidisciplinary, inter-organizational team. Funding was provided from provincial organizations to create new positions within the Program and to support stakeholder engagement throughout the process of implementation. Data were collected from local and national databases regarding the amount of IVIG used and appropriateness of orders based on published criteria. RESULTS: Over 20 months, the Program helped to reduce unnecessary IVIG use from pre-intervention levels by more than 20%. Interventions from nurse navigators alone reduced inappropriate IVIG use by 2.6%. During the 20-month period following Program initiation, more than 4 million CAD less was spent on IVIG compared with the previous 20 months. CONCLUSION: The Saskatchewan IG Stewardship Program has led to more appropriate IVIG use across the province, more effective preservation of this limited healthcare resource, and cost savings that more than cover the cost of administering the Program.

Core principles of Malakit intervention for transferability in other contexts.

To eliminate malaria, all populations must be included. For those who are not reached by the health care system, specific interventions must be tailor-made. An innovative Malakit strategy, based on the distribution of self-diagnosis and self-treatment kits, has been evaluated in the Suriname-French Guiana- Amapá (Brazil) region. The results showed effectiveness and good acceptability. The Malakit intervention is complex and has many components. Its transferability requires adaptation to other populations and regions, while retaining the main features of the intervention. This article provides the keys to adapting, implementing and evaluating it in other contexts facing residual malaria in hard-to-reach and/or mobile populations. The process of transferring this intervention includes: diagnosis of the situation (malaria epidemiology, characteristics of the population affected) to define the relevance of the strategy; determination of the stakeholders and the framework of the intervention (research project or public health intervention); adaptation modalities (adaptation of the kit, training, distribution strategy); the role of community health workers and their need for training and supervision. Finally, evaluation needs are specified in relation to prospects for geographical or temporal extension. Malaria elimination is likely to increasingly involve marginalized people due to climate change and displacement of populations. Evaluation of the transferability and effectiveness of the Malakit strategy in new contexts will be essential to increase and refine the evidence of its value, and to decide whether it could be an additional tool in the arsenal recommended in future WHO guidelines.

Implementation of post-discharge malaria chemoprevention (PDMC) in Benin, Kenya, Malawi, and Uganda: stakeholder engagement meeting report.

A Stakeholder engagement meeting on the implementation of post-discharge malaria chemoprevention (PDMC) in Benin, Kenya, Malawi, and Uganda was held in Nairobi, Kenya, on 27 September 2023. Representatives from the respective National Malaria Control Programmes, the World Health Organization (WHO) Geneva, Africa Regional and Kenya offices, research partners, non-governmental organizations, and the Medicines for Malaria Venture participated. PDMC was recommended by the WHO in June 2022 and involves provision of a full anti-malarial treatment course at regular intervals during the post-discharge period in children hospitalized with severe anaemia in areas of moderate-to-high malaria transmission. The WHO recommendation followed evidence from a meta-analysis of three clinical trials and from acceptability, delivery, cost-effectiveness, and modelling studies. The trials were conducted in The Gambia using monthly sulfadoxine-pyrimethamine during the transmission season, in Malawi using monthly artemether-lumefantrine, and in Kenya and Uganda using monthly dihydroartemisinin-piperaquine, showing a significant reduction in all-cause mortality by 77% (95% CI 30-98) and a 55% (95% CI 44-64) reduction in all-cause hospital readmissions 6 months post-discharge. The recommendation has not yet been implemented in sub-Saharan Africa. There is no established platform for PDMC delivery. The objectives of the meeting were for the participating countries to share country contexts, plans and experiences regarding the adoption and implementation of PDMC and to explore potential delivery platforms in each setting. The meeting served as the beginning of stakeholder engagement within the PDMC Saves Lives project and will be followed by formative and implementation research to evaluate alternative delivery strategies in selected countries. Meeting highlights included country consensus on use of dihydroartemisinin-piperaquine for PDMC and expansion of the target group to "severe anaemia or severe malaria", in addition to identifying country-specific options for PDMC delivery for evaluation in implementation research. Further exploration is needed on whether the age group should be extended to school-age children.

Targets for De-implementation of Unnecessary Testing Before Low-Risk Surgery: A Qualitative Study.

INTRODUCTION: Despite multispecialty recommendations to avoid routine preoperative testing before low-risk surgery, the practice remains common and de-implementation has proven difficult. The goal of this study as to elicit determinants of unnecessary testing before low-risk surgery to inform de-implementation efforts. METHODS: We conducted focused ethnography at a large academic institution, including semi-structured interviews and direct observations at two preoperative evaluation clinics and one outpatient surgery center. Themes were identified through narrative thematic analysis and mapped to a comprehensive and integrated checklist of determinants of practice, the Tailored Implementation for Chronic Diseases framework (TICD). RESULTS: Thirty individuals participated (surgeons, anesthesiologists, primary care physicians, physician assistants, nurses, and medical assistants). Three themes were identified: (1) Shared Values (TICD Social, Political, and Legal Factors), (2) Gaps in Knowledge (TICD Individual Health Professional Factors, Guideline Factors), and (3) Communication Breakdown (TICD Professional Interactions, Incentives and Resources, Capacity for Organizational Change). Shared Values describe core tenets expressed by all groups of clinicians, namely prioritizing patient safety and utilizing evidence-based medicine. Clinicians had Gaps in Knowledge related to existing data and preoperative testing recommendations. Communication Breakdowns within interdisciplinary teams resulted in unnecessary testing ordered to meet perceived expectations of other providers. CONCLUSIONS: Clinicians have knowledge gaps related to preoperative testing recommendations and may be amenable to de-implementation efforts and educational interventions. Consensus guidelines may streamline interdisciplinary communication by clarifying interdisciplinary needs and reducing testing ordered to meet perceived expectations of other clinicians.

Interventions and contextual factors to improve retention in care for patients with hypertension in primary care: Hermeneutic systematic review.

BACKGROUND: Regular engagement over time in hypertension care, or retention, is a crucial but understudied step in optimizing patient outcomes. This systematic review leverages a hermeneutic methodology to identify, evaluate, and quantify the effects of interventions and contextual factors for improving retention for patients with hypertension. METHODS: We searched for articles that were published between 2000 and 2022 from multiple electronic databases, including MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials, clinicaltrials.gov, and WHO International Trials Registry. We followed the latest version of the preferred reporting items for systematic reviews and meta-analyses (PRISMA) guideline to report the findings for this review. We also synthesized the findings using a hermeneutic methodology for systematic reviews, which used an iterative process to review, integrate, analyze, and interpret evidence. RESULTS: From 4686 screened titles and abstracts, 18 unique studies from 9 countries were identified, including 10 (56%) randomized controlled trials (RCTs), 3 (17%) cluster RCTs, and 5 (28%) non-RCT studies. The number of participants ranged from 76 to 1562. The overall mean age range was 41-67 years, and the proportion of female participants ranged from 0% to 100%. Most (n = 17, 94%) studies used non-physician personnel to implement the proposed interventions. Fourteen studies (78%) implemented multilevel combinations of interventions. Education and training, team-based care, consultation, and Short Message Service reminders were the most common interventions tested. CONCLUSIONS: This review presents the most comprehensive findings on retention in hypertension care to date and fills the gaps in the literature, including the effectiveness of interventions, their components, and contextual factors. Adaptation of and implementing HIV care models, such differentiated service delivery, may be more effective and merit further study. REGISTRATION: CRD42021291368.
