Attribute Development in Health-Related Discrete Choice Experiments: A Systematic Review of Qualitative Methods and Techniques to Inform Quantitative Instruments.

OBJECTIVES: This review sought to identify the qualitative methods and techniques that researchers have used in the past decade to develop attributes and inform health-related discrete choice experiments (DCEs) surveys from a patient perspective. METHODS: The review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines for reporting systematic reviews. An adapted appraisal tool following guidelines for reporting qualitative research for quantitative instruments and criteria for attribute development in DCEs was applied for quality assessment and data extraction. A narrative approach was used to synthesize data. This examination included consideration of issues pertaining to sampling, data collection, data analysis, attribute list reduction, wording, methodological adaptations to capture patient preferences, and testing the pre-experimental design decisions of the DCE survey. RESULTS: Of 8505 articles identified for abstract screening, 680 were included for full-text screening, 36 of which met the inclusion criteria. Practices to improve methodological robustness included pre-data collection materials to inform instruments, data collection methods specific for decision-making scenarios, purposeful selection of data analysis methods to address the research question, and participants' involvement in reducing the list of attributes. Examples of methodological adaptations for patients were noted. CONCLUSIONS: DCEs have the potential to become a mixed-method approach in which the qualitative phase informs a reduced list of attributes for a survey, serves the predesign decisions of the experiment by testing trade-offs, overlapping, understandability, face, and content validity and provides explanations of the quantitative results. Establishing guidelines for using qualitative methods for DCE attribute development may help to broadly enhance the methodological robustness of DCEs.

Demographic Determinants Influencing the Adoption of Genetic Testing for Cardiovascular Diseases in Japan　- Insights From a Large-Scale Online Survey.

Background: Genetic testing for cardiovascular diseases (CVD) is vital, but is underutilized in Japan due to limited insurance coverage, accessibility, and public disinterest. This study explores demographic factors influencing the decision to undergo CVD genetic testing. Methods and Results: We compared the CVD history and baseline demographics of Japanese adults who underwent genetic testing with those who did not, using an Internet survey. The regression model indicated that men, the young, married individuals, parents, and those with CVD, higher score for rationality, and lower quality of life were more inclined to undergo testing. Conclusions: Targeting strategies for CVD genetic testing could focus on these demographics.

A cost-benefit analysis of mass prostate cancer screening.

BACKGROUND: Prostate cancer (PCa) causes a substantial health and financial burden worldwide, underscoring the need for efficient mass screening approaches. This study attempts to evaluate the Net Cost-Benefit Index (NCBI) of PCa screening in Iran to offer insights for informed decision-making and resource allocation. METHOD: The Net Cost-Benefit Index (NCBI) was calculated for four age groups (40 years and above) using a decision-analysis model. Two screening strategies, prostate-specific antigen (PSA) solely and PSA with Digital Rectal Examination (DRE), were evaluated from the health system perspective. A retrospective assessment of 1402 prostate cancer (PCa) patients' profiles were conducted, and direct medical and non-medical costs were calculated based on the 2021 official tariff rates, patient records, and interviews. The monetary value of mass screening was determined through Willingness to Pay (WTP) assessments, which served as a measure for the benefit aspect. RESULT: The combined PSA and DRE strategy of screening is cost-effective, yields up to $3 saving in costs per case and emerges as the dominant strategy over PSA alone. Screening for men aged 70 and above does not meet economic justification, indicated by a negative Net Cost-Benefit Index (NCBI). The 40-49 age group exhibits the highest net benefit, $13.81 based on basic information and $13.54 based on comprehensive information. Sensitivity analysis strongly supports the cost-effectiveness of the combined screening approach. CONCLUSION: This study advocates prostate cancer screening with PSA and DRE, is economically justified for men aged 40-69. The results of the study recommend that policymakers prioritize resource allocation for PCa screening programs based on age and budget constraints. Men's willingness to pay, especially for the 40-49 age group which had the highest net benefit, leverages their financial participation in screening services. Additionally, screening services for other age groups, such as 50-54 or 55-59, can be provided either for free or at a reduced cost.

Exploring pre-pandemic patterns of vaccine decision-making with the 5C model: results from representative surveys in 2016 and 2018.

BACKGROUND: The 5C psychological antecedents of vaccination (Confidence, Complacency, Constraints, Calculation, and Collective Responsibility) facilitate understanding vaccination decisions in specific target groups as well as the general public's informational needs. This study aims to explain pre-pandemic vaccination behaviour (a) in general, (b) for specific vaccines such as influenza, and (c) for certain target groups (e.g. people over the age of 59 years, parents, healthcare workers), using the 5C model and sociodemographic variables. The intention to get an influenza vaccination was also analysed for target groups. METHODS: The 5C, self-reported vaccination behaviour and the intention to vaccinate were collected in two representative telephone surveys in Germany - one in 2016 (n1 = 5,012) and another in 2018 (n2 = 5,054). Parents, people over the age of 59 years, chronically ill people, people with a migratory background, pregnant women and healthcare workers were target groups. RESULTS: Overall, the 5C model had higher explanatory power than sociodemographic variables. The pattern of vaccine hesitancy slightly differed between vaccinations and target groups. Confidence in safety and effectiveness was always a significant predictor. Complacency (the underestimation of disease risks) and Constraints were significant predictors as well. Calculation (of risks and benefits) was important for influenza vaccination intentions. CONCLUSIONS: This work builds an important benchmark for understanding potential changes in vaccine acceptance due to the pandemic. The benchmark can be used in research on potential effects of the pandemic on vaccination behaviours. Intervention designers can also use the results to understand specific audiences and their vaccination decisions.

COVSIM: A stochastic agent-based COVID-19 SIMulation model for North Carolina.

We document the evolution and use of the stochastic agent-based COVID-19 simulation model (COVSIM) to study the impact of population behaviors and public health policy on disease spread within age, race/ethnicity, and urbanicity subpopulations in North Carolina. We detail the methodologies used to model the complexities of COVID-19, including multiple agent attributes (i.e., age, race/ethnicity, high-risk medical status), census tract-level interaction network, disease state network, agent behavior (i.e., masking, pharmaceutical intervention (PI) uptake, quarantine, mobility), and variants. We describe its uses outside of the COVID-19 Scenario Modeling Hub (CSMH), which has focused on the interplay of nonpharmaceutical and pharmaceutical interventions, equitability of vaccine distribution, and supporting local county decision-makers in North Carolina. This work has led to multiple publications and meetings with a variety of local stakeholders. When COVSIM joined the CSMH in January 2022, we found it was a sustainable way to support new COVID-19 challenges and allowed the group to focus on broader scientific questions. The CSMH has informed adaptions to our modeling approach, including redesigning our high-performance computing implementation.

Spatial multi-criteria decision analysis for the selection of sentinel regions in tick-borne disease surveillance.

BACKGROUND: The implementation of cost-effective surveillance systems is essential for tracking the emerging risk of tick-borne diseases. In Canada, where Lyme disease is a growing public health concern, a national sentinel surveillance network was designed to follow the epidemiological portrait of this tick-borne disease across the country. The surveillance network consists of sentinel regions, with active drag sampling carried out annually in all regions to assess the density of Ixodes spp. ticks and prevalence of various tick-borne pathogens in the tick population. The aim of the present study was to prioritize sentinel regions by integrating different spatial criteria relevant to the surveillance goals. METHODS: We used spatially-explicit multi-criteria decision analyses (MCDA) to map priority areas for surveillance across Canada, and to evaluate different scenarios using sensitivity analyses. Results were shared with stakeholders to support their decision making for the selection of priority areas to survey during active surveillance activities. RESULTS: Weights attributed to criteria by decision-makers were overall consistent. Sensitivity analyses showed that the population criterion had the most impact on rankings. Thirty-seven sentinel regions were identified across Canada using this systematic and transparent approach. CONCLUSION: This novel application of spatial MCDA to surveillance network design favors inclusivity of nationwide partners. We propose that such an approach can support the standardized planning of spatial design of sentinel surveillance not only for vector-borne disease BDs, but more broadly for infectious disease surveillance where spatial design is an important component.

GRADE Concept 7: Issues and Insights Linking Guideline Recommendations to Trustworthy Essential Medicine Lists.

OBJECTIVES: Guidelines and essential medicine lists (EMLs) bear similarities and differences in the process that lead to decisions. Access to essential medicines is central to achieve universal health coverage. The World Health Organization (WHO) EML has guided prioritization of essential medicines globally for nearly 50 years, and national EMLs (NEMLs) exist in over 130 countries. Guideline and EML decisions, at WHO or national levels, are not always coordinated and aligned. We sought to explore challenges, and potential solutions, for decision-making to support trustworthy medicine selection for EMLs from a Grading of Recommendations, Assessment, Development and Evaluations (GRADE) Working Group perspective. We primarily focus on the WHO EML; however, our findings may be applicable to NEML decisions as well. STUDY DESIGN AND SETTING: We identified key challenges in connecting the EML to health guidelines by involving a broad group of stakeholders and assessing case studies including real applications to the WHO EML, South Africa NEML, and a multiple sclerosis guideline connected to a WHO EML application for multiple sclerosis treatments. To address challenges, we utilized the results of a survey and feedback from the stakeholders, and iteratively met as a project group. We drafted a conceptual framework of challenges and potential solutions. We presented a summary of the results for feedback to all attendees of the GRADE Working Group meetings in November 2022 (approximately 120 people) and in May 2023 (approximately 100 people) before finalizing the framework. RESULTS: We prioritized issues and insights/solutions that addressed the connections between the EML and health guidelines. Our suggested solutions include early planning alignment of guideline groups and EMLs, considering shared participation to strengthen linkage, further clarity on price/cost considerations, and using explicit shared criteria to make guideline and EML decisions. We also provide recommendations to strengthen the connection between WHO EML and NEMLs including through contextualization methods. CONCLUSION: This GRADE concept article, jointly developed by key stakeholders from the guidelines and EMLs field, identified key conceptual issues and potential solutions to support the continued advancement of trustworthy EMLs. Adopting structured decision criteria that can be linked to guideline recommendations bears the potential to advance health equity and gaps in availability of essential medicines within and between countries.

West Australian parents' views on vaccinating their children against COVID-19: a qualitative study.

BACKGROUND: Australian children and adolescents were among the last local cohorts offered COVID-19 vaccines. Despite promising initial uptake, coverage subsequently plateaued, requiring further efforts to improve access and build parents' recognition of the importance of COVID-19 vaccination. We sought to understand West Australian (WA) parents' willingness to vaccinate their children to inform strategies for improving uptake at the time in which they were becoming eligible. METHODS: We undertook in-depth qualitative interviews with 30 parents of children aged 5-17 years from June - December 2021. During this period, children aged 12-15 years became eligible for vaccination; children aged 5-11 years became eligible shortly thereafter. Data were thematically analysed in NVivo. RESULTS: Most parents intended on vaccinating their children once eligible. Parents sought to protect their children, to protect the community, to resume travel, and to get back to "normal". They reflected that vaccination against key infectious threats is a routine activity in childhood. Some were concerned about the vaccine, particularly mRNA vaccines, being new technology or impacting fertility. "Wait-awhiles" wanted to see what other parents would do or were delaying until they felt that there was a higher risk of COVID-19 in WA. Most parents of younger children wanted their child to be vaccinated at the general practice clinic due to familiarity and convenience. Parents were particularly eager for clear and consistent messaging about vaccination of children and adolescents, including safety, importance, scientific evidence, and personal stories. CONCLUSION: For future pandemic vaccinations pertaining to children, governments and health officials need to address parents' concerns and meet their preferences for the delivery of the vaccine program to children and adolescents.

Factors Influencing Genetic Screening Enrollment among a Diverse, Community-Ascertained Cohort.

INTRODUCTION: Genetic screening for preventable adult-onset hereditary conditions has been proposed as a mechanism to reduce health disparities. Analysis of how race and ethnicity influence decision-making to receive screening can inform recruitment efforts and more equitable population screening design. A study at the University of Washington Medicine that invited unselected patients to participate in genetic screening for pathogenic variation in medically important genes provided an opportunity to evaluate these factors. METHODS: We analyzed screening enrollee survey data to understand factors most important and least important in decision-making about screening overall and across different race and ethnicity groups. Electronic health record race and ethnicity and survey-reported race and ethnicity were compared to assist with interpretation. Comments provided about reasons for not enrolling in screening were analyzed using content analysis. RESULTS: Overall, learning about disease risk and identifying risk early for prevention purposes were important factors in decision-making to receive screening, and regrets about screening and screening being against one's moral code were not viewed as important. Although racial identity was challenging to assign in all cases, compared to other enrollees, African-American and Asian enrollees considered test accuracy and knowing more about the test to be of greater importance. Three themes emerged related to nonparticipation: benefits do not outweigh risks, don't want to know, and challenges with study logistics. CONCLUSION: Our results highlight important motivators for receiving screening and areas that can be addressed to increase screening interest and accessibility. This knowledge can inform future population screening program design including recruitment and education approaches.

Which measures of perceived vulnerability predict protective intentions-and when?

Assessing perceived vulnerability to a health threat is essential to understanding how people conceptualize their risk, and to predicting how likely they are to engage in protective behaviors. However, there is limited consensus about which of many measures of perceived vulnerability predict behavior best. We tested whether the ability of different measures to predict protective intentions varies as a function of the type of information people learn about their risk. Online participants (N = 909) read information about a novel respiratory disease before answering measures of perceived vulnerability and vaccination intentions. Type-of-risk information was varied across three between-participant groups. Participants learned either: (1) only information about their comparative standing on the primary risk factors (comparative-only), (2) their comparative standing as well as the base-rate of the disease in the population (+ base-rate), or (3) their comparative standing as well as more specific estimates of their absolute risk (+ absolute-chart). Experiential and affective measures of perceived vulnerability predicted protective intentions well regardless of how participants learned about their risk, while the predictive ability of deliberative numeric and comparative measures varied based on the type of risk information provided. These results broaden the generalizability of key prior findings (i.e., some prior findings about which measures predict best may apply no matter how people learn about their risk), but the results also reveal boundary conditions and critical points of distinction for determining how to best assess perceived vulnerability.

Feasibility of a screening algorithm for chronic thromboembolic pulmonary hypertension: The OSIRIS study.

INTRODUCTION: Chronic thromboembolic pulmonary hypertension (CTEPH) is a long-term sequel to pulmonary embolism (PE) whose incidence varies according to different published studies. We have carried out this study to determine its incidence within 2 years after index pulmonary embolism and to study limitations to an early diagnosis. MATERIAL AND METHODS: OSIRIS is a multicentre, longitudinal cohort study. Patients were followed for 3, 6, 12, and 24 months after pulmonary embolism using a structured three-step algorithm. A physician-centered questionnaire at least one positive response in a screening proceeded to the second step, transthoracic echocardiography. The third step consisted of ventilation/perfusion lung scintigraphy and right heart catheterisation. A transthoracic echocardiography was performed in patients without positive response in the screening questionnaire after 2 years. CTEPH diagnosis required haemodynamic confirmation by right heart catheterisation and mismatched perfusion defects on lung scintigraphy. RESULTS: A total of 1191 patients were enrolled in 18 Spanish hospitals. Cumulative CTEPH incidence after 2-years PE was: 2.49 % (95 % CI: 1.68-3.56) and the incidence rate of CTEPH was 1.1 cases per 1000 person-months (95 % CI: 0.725; 1.60). The CTEPH algorithm presented a lack of adherence of 29 %; patient and physician preferences posed barriers to the triage algorithm The screening questionnaire, in patients who completed the follow-up, shows a specificity of 91.3 % (89.0-93.2 %) and negative predictive value of 99.4 % (98.4-99.8 %).. CONCLUSIONS: OSIRIS provides practiced clinical based data on the chronic thromboembolic pulmonary hypertension incidence and identified barriers to the implementation of a 3-step triage algorithm for its detection. CLINICAL TRIAL REGISTRATION: clinicaltrials.gov identifier: NCT03134898.

Clinical and psychosocial constructs for breast, cervical, and colorectal cancer screening participation: A systematic review

Research has identified a wide range of psychosocial factors associated to choosing to engage in ongoing cancer screenings. Nevertheless, a systematic review of the theoretical frameworks and constructs underpinning studies on breast, cervical, and colorectal cancer screening participation has yet to be conducted. As part of the action-research project “Miriade,” the present study aims to identifying the main theoretical frameworks and constructs adopted in the literature over the past five years to explain cancer screening participation. According to the PRISMA guidelines, a search of the MEDLINE/PubMed and PsycINFO databases was made. Empirical studies conducted from 2017 to 2021 were included. The following keywords were used: breast OR cervical OR colorectal screening AND adhesion OR participation OR engagement AND theoretical framework OR conceptual framework OR theory. Overall, 24 articles met the inclusion criteria. Each theoretical framework highlighted clinical and psychosocial constructs of cancer screening participation, focusing on the individuals (psycho-emotional functioning and skills plan) and/or the health services perspectives. Findings from the present study acknowledge the plurality of the theoretical frameworks and constructs adopted to predict or promote breast, cervical, and colorectal cancer screening adhesion and the need for new research efforts to improve the effectiveness of cancer screening promotion interventions.

An examination of relational dynamics of power in the context of supported (assisted) decision-making with older people and those with disabilities in an acute healthcare setting.

INTRODUCTION: Supported (assisted) healthcare decision-making (ADM) focuses attention on how people with disabilities, including cognitive impairments, can be best supported to make decisions about their health and social care on an equitable basis with others. Meaningful implementation of legal frameworks for ADM challenges long-held presumptions about who has access to valued decision-making resources, influence and power within a particular socio-cultural setting. This study aims to explore the relational power dynamics around ADM with older people in acute care settings. METHODS: This study adopts a critical hermeneutic approach to qualitatively explore the lived experience of ADM from the perspectives of Health and Social Care Professionals (N = 26). This is supported by an exploration of the experiences of older people (N = 4), older people with a diagnosis of dementia (N = 4) and family carers (N = 5). RESULTS: We present three themes of data analysis that represent three spaces where the relational aspects of power in ADM are manifested. The first space, centralising decision-making power within multidisciplinary teams identified the privileging of physicians in traditional hierarchical leadership models that may lead to the implicit exclusion of family carers and some Health and Social Care Professionals in the ADM process. Privileging cognitive and communication competence identified a tendency to attribute decision-making autonomy to those with cognitive and communication competency. The final space, balancing the duty of care and individual autonomy, recognises acute care settings as typically risk-averse cultures that limit autonomy for decisions that carry risk, especially for those with cognitive impairment. CONCLUSION: Findings indicate the need to address cultural sources of power operating through social norms premised on ageist and ableist ideologies. It is necessary to challenge institutional barriers to meaningful ADM including positional power that is associated with hierarchies of influence and protectionism. Finally, meaningful ADM requires resistance to the disempowerment created by structural, economic and social circumstances which limit choices for decision-making. PATIENT OR PUBLIC CONTRIBUTION: A public and patient involvement panel of older people were consulted in the development of the grant application (HRB: APA-2016-1878). Representatives from Alzheimer's Society Ireland and Family Carers Ireland were steering committee members guiding design and strategy.

Política interministerial para la investigación, transferencia y fortalecimiento de la salud en territorio, una experiencia federal / Interministerial Policy for Research, Transfer and Strengthening of Health in the Territory, a Federal Experience

RESUMEN INTRODUCCIÓN: En marzo de 2023, en el marco del "Convenio Marco de Cooperación y Asistencia Técnica Mutua - MSAL/MINCYT", se creó el "Proyecto Federal Interministerial de Investigación, Transferencia y Fortalecimiento para la Salud en Territorio". El objetivo fue presentar un proceso de trabajo innovador entre dos ministerios, que sienta las bases para configurar un modelo de gestión de las políticas de investigación en salud con asiento federal y tendiente a potenciar las funciones y capacidades institucionales de cada sector. MÉTODOS: La coordinación del Proyecto se encuentra a cargo de un Comité Interministerial. En 2023 se realizó la Convocatoria para la presentación de un proyecto anual, que consta de dos componentes: A) Línea de investigación y transferencia; y B) Plan de fortalecimiento de las capacidades institucionales de las áreas de investigación de los ministerios de salud jurisdiccionales agrupadas en la Red Ministerial de Áreas de Investigación en Salud de Argentina. RESULTADOS: Las 24 jurisdicciones presentaron sus proyectos, y todos ellos resultaron aprobados. La estrategia tuvo un impacto en el fortalecimiento de los mecanismos de trabajo conjunto de dos ministerios nacionales, que debieron armonizar modalidades de gestión entre las áreas de investigación en salud y las representaciones de CyT en el ámbito jurisdiccional y entre los decisores en materia sanitaria y los actores del sistema científico. DISCUSIÓN: Esta experiencia contribuye a fortalecer las capacidades estatales, a la vez que permite identificar aspectos que requieren continuar siendo trabajados para consolidar nuevas modalidades de gestión interministeriales.

ABSTRACT INTRODUCTION: In March 2023, within the framework of the "Framework Agreement for Cooperation and Mutual Technical Assistance - MSAL/MINCYT", the "Federal Interministerial Project of Research, Transfer and Strengthening for Health in the Territory" was created. The objective was to present an innovative work process between the Ministry of Health (MSAL) and the Ministry of Science, Technology and Innovation (MINCYT), that lays the foundations for a management model of health research policies with a federal approach and aimed at enhancing the institutional functions and capacities of each sector. METHODS: The Project was coordinated by an Interministerial Committee. In 2023 there was a Call for the presentation of an annual project that consists of two components: A) Line of research and transfer; and B) Plan to strengthen the institutional capacities of the research areas of the jurisdictional health ministries grouped in REMINSA. RESULTS: The 24 jurisdictions presented their projects, and all of them were approved. The strategy strengthened the joint work mechanisms of two national ministries, that had to harmonize management patterns between health research areas and S&T representations at the jurisdictional level and between health decision-makers and the actors of the scientific system. DISCUSSION: This experience contributes to strengthening state capacities, while allowing to identify aspects that require continued work to reinforce new interministerial management patterns.

The GIN-McMaster guideline tool extension for the integration of quality improvement and quality assurance in guidelines: a description of the methods for its development.

BACKGROUND AND OBJECTIVES: Our objective was to develop an extension of the widely used GIN-McMaster Guideline Development Checklist and Tool for the integration of quality assurance and improvement (QAI) schemes with guideline development. METHODS: We used a mixed-methods approach incorporating evidence from a systematic review, an expert workshop and a survey of experts to iteratively create an extension of the checklist for QAI through three rounds of feedback. As a part of this process, we also refined criteria of a good guideline-based quality indicator. RESULTS: We developed a 40-item checklist extension addressing steps for the integration of QAI into guideline development across the existing 18 topics and created one new topic specific to QAI. The steps span from 'organization, budget, planning and training', to updating of QAI and guideline implementation. CONCLUSION: The tool supports integration of QAI schemes with guideline development initiatives and it will be used in the forthcoming integrated European Commission Initiative on Colorectal Cancer. Future work should evaluate this extension and QAI items requiring additional support for guideline developers and links to QAI schemes.

Uncertainty in healthcare and health decision making: Five methodological and conceptual research recommendations from an interdisciplinary team.

Uncertainty is prevalent in various health contexts. It is imperative to understand how health-related uncertainty can impact individuals' healthcare experiences and health decision making. The purpose of the present paper is to provide five overarching recommendations from an interdisciplinary team of experts to address gaps in the literature on health-related uncertainty. We present a case study of health-related uncertainty within the specific context of alcohol use to demonstrate these gaps and provide context for the recommendations. The five recommendations concerning health-related uncertainty include: (1) use common, consistent terminology to discuss uncertainty, (2) clarify measures of individual differences in response to uncertainty, (3) increase research on uncertainty and affect, (4) investigate the impact of the channel through which uncertainty is communicated, and (5) develop theory-driven interventions to improve uncertainty management. We conclude by reviewing health contexts in which health-related uncertainty exists and note how our recommendations complement existing reviews and data.

Medication Abortion and Abortion Pill Reversal: An Exploratory Analysis on the Influence of Others in Women's Decision-Making.

Introduction As medication abortion accounts for a growing share of abortions in the United States, an increasing number of women are seeking abortion pill reversal (APR). These decisions are typically not made in isolation. However, little research exists on women's APR decision-making and the role played by people close to them. Methods We surveyed women who contacted a national hotline for information on APR and who completed a two-week treatment protocol with progesterone (n = 67). We analyzed women's open-ended answers using thematic analysis to identify memorable messages about medication abortion and APR. Participants' communication with other people in their lives was assessed using the Isolation subscale of the Individual Level Abortion Stigma (ILAS) scale, and decision-making difficulty was assessed using a Likert scale. Results Thirty-six respondents met the eligibility criteria and filled out the ILAS and decision-difficulty scales. Women tended to talk with family and friends about their medication abortion decisions, while they typically sought information online when deciding about APR. Women reported greater stigma in their disclosures about their abortions than in their disclosures about APR (p = 0.006). Conclusion Memorable messages influence women's decisions to pursue medication abortion and APR.

Impacts of timing, length, and intensity of behavioral interventions to COVID-19 dynamics: North Carolina county-level examples.

We sought to examine how the impact of revocable behavioral interventions, e.g., shelter-in-place, varies throughout an epidemic, as well as the role that the proportion of susceptible individuals had on an intervention's impact. We estimated the theoretical impacts of start day, length, and intensity of interventions on disease transmission and illustrated them on COVID-19 dynamics in Wake County, North Carolina, to inform how interventions can be most effective. We used a Susceptible, Exposed, Infectious, and Recovered (SEIR) model to estimate epidemic curves with modifications to the disease transmission parameter (ß). We designed modifications to simulate events likely to increase transmission (e.g., long weekends, holiday seasons) or behavioral interventions likely to decrease it (e.g., shelter-in-place, masking). We compared the resultant curves' shape, timing, and cumulative case count to baseline and across other modified curves. Interventions led to changes in COVID-19 dynamics, including moving the peak's location, height, and width. The proportion susceptible, at the start day, strongly influenced their impact. Early interventions shifted the curve, while interventions near the peak modified shape and case count. For some scenarios, in which the transmission parameter was decreased, the final cumulative count increased over baseline. We showed that the timing of revocable interventions has a strong impact on their effect. The same intervention applied at different time points, corresponding to different proportions of susceptibility, resulted in qualitatively differential effects. Accurate estimation of the proportion susceptible is critical for understanding an intervention's impact. The findings presented here provide evidence of the importance of estimating the proportion of the population that is susceptible when predicting the impact of behavioral infection control interventions. Greater emphasis should be placed on the estimation of this epidemic component in intervention design and decision-making. Our results are generic and are applicable to other infectious disease epidemics, as well as to future waves of the current COVID-19 epidemic. Developed into a publicly available tool that allows users to modify the parameters to estimate impacts of different interventions, these models could aid in evaluating behavioral intervention options prior to their use and in predicting case increases from specific events.
