Effectiveness of e-cigarettes as a stop smoking intervention in adults: a systematic review.

BACKGROUND: This systematic review aims to identify the benefits and harms of electronic cigarettes (e-cigarettes) as a smoking cessation aid in adults (aged ≥ 18 years) and to inform the development of the Canadian Task Force on Preventive Health Care's (CTFPHC) clinical practice guidelines on e-cigarettes. METHODS: We searched Ovid MEDLINE®, Ovid MEDLINE® Epub Ahead of Print, In-Process & Other Non-Indexed Citations, PsycINFO, Embase Classic + Embase, and the Cochrane Library on Wiley. Searches were conducted from January 2016 to July 2019 and updated on 24 September 2020 and 25 January 2024. Two reviewers independently performed title-abstract and full-text screening according to the pre-determined inclusion criteria. Data extraction, quality assessments, and the application of Grading of Recommendations Assessment, Development and Evaluation (GRADE) were performed by one independent reviewer and verified by another. RESULTS: We identified 18 studies on 17 randomized controlled trials that compared e-cigarettes with nicotine to e-cigarettes without nicotine and e-cigarettes (with or without nicotine) to other interventions (i.e., no intervention, waitlist, standard/usual care, quit advice, or behavioral support). Considering the benefits of e-cigarettes in terms of smoking abstinence and smoking frequency reduction, 14 studies showed small or moderate benefits of e-cigarettes with or without nicotine compared to other interventions; although, with low, very low or moderate evidence certainty. With a focus on e-cigarettes with nicotine specifically, 12 studies showed benefits in terms of smoking abstinence when compared with usual care or non-nicotine e-cigarettes. In terms of harms following nicotine or non-nicotine e-cigarette use, 15 studies reported mild adverse events with little to no difference between groups and low to very low evidence certainty. CONCLUSION: The evidence synthesis on the e-cigarette's effectiveness shows data surrounding benefits having low to moderate evidence certainty for some comparisons and very low certainty for others, indicating that e-cigarettes may or probably increase smoking cessation, whereas, for harms, there is low to very low evidence certainty. Since the duration for outcome measurement varied among different studies, it may not be long-term enough for Adverse Events (AEs) to emerge, and there is a need for more research to understand the long-term benefits and potential harms of e-cigarettes.

Evaluation of the sensitivity of a measles diagnostic real-time RT-PCR assay incorporating recently observed priming mismatch variants, 2024.

We investigated a variant of measles virus that encodes three mismatches to the reverse priming site for a widely used diagnostic real-time RT-PCR assay; reduction of sensitivity was hypothesised. We examined performance of the assay in context of the variant using in silico data, synthetic RNA templates and clinical specimens. Sensitivity was reduced observed at low copy numbers for templates encoding the variant sequence. We designed and tested an alternate priming strategy, rescuing the sensitivity of the assay.

Effectiveness of smoking cessation interventions among adults: an overview of systematic reviews.

BACKGROUND: This overview of reviews aims to identify evidence on the benefits (i.e. tobacco use abstinence and reduction in smoking frequency) and harms (i.e. possible adverse events/outcomes) of smoking cessation interventions among adults aged 18 years and older. METHODS: We searched Medline, Embase, PsycINFO, Cochrane Database of Systematic Reviews, Database of Abstracts of Reviews of Effects, the CADTH Health Technology Assessment Database and several other websites for grey literature. Searches were conducted on November 12, 2018, updated on September 24, 2020, with publication years 2008 to 2020. Two reviewers independently performed title-abstract and full-text screening considering pre-determined inclusion criteria. Data extraction and quality assessments were initially completed by two reviewers independently (i.e. 73% of included studies (n = 22)) using A Measurement Tool to Assess Systematic Reviews-2 (AMSTAR 2), and the remainder done by one reviewer and verified by another due to resources and feasibility. The application of Grading of Recommendations Assessment, Development and Evaluation (GRADE) was performed by one independent reviewer and verified by another. RESULTS: A total of 22 Cochrane systematic reviews evaluating the impact of smoking cessation interventions on outcomes such as tobacco use abstinence, reduction in smoking frequency, quality of life and possible adverse events were included. Pharmaceutical (i.e. varenicline, cytisine, nicotine replacement therapy (NRT), bupropion) and behavioural interventions (i.e. physician advice, non-tailored print-based self-help materials, stage-based individual counselling, etc.) showed to have increased smoking cessation; whereas, data for mobile phone-based interventions including text messaging, hypnotherapy, acupuncture, continuous auricular stimulation, laser therapy, electrostimulation, acupressure, St John's wort, S-adenosyl-L-methionine (SAMe), interactive voice response systems and other combination treatments were unclear. Considering harms related to smoking cessation interventions, small/mild harms (i.e. increased palpitations, chest pain, nausea, insomnia, headache) were observed following NRT, varenicline and cytisine use. There were no data on harms related to behavioural therapies (i.e. individual or group counselling self-help materials, internet interventions), combination therapies or other therapies (i.e. laser therapy, electrostimulation, acupressure, St John's wort, SAMe). CONCLUSION: Results suggest that pharmacological and behavioural interventions may help the general smoking population quit smoking with observed small/mild harms following NRT or varenicline. Consequently, evidence regarding ideal intervention strategies and the long-term impact of these interventions for preventing smoking was unclear.

An Institutional Approach to Equity and Improvement in Child Health Outcomes.

Pediatric health inequities are pervasive. Approaches by health care institutions to address inequities often, and increasingly, focus on social needs screening without linked, robust responses. Even when actions in pursuit of health equity do occur within health care institutions, efforts occur in isolation from each other, standing in the way of cross-learning and innovation. Learning network methods hold promise when institutions are confronted with complex, multidimensional challenges. Equity-oriented learning networks may therefore accelerate action to address complex factors that contribute to inequitable pediatric health outcomes, enabling rapid learning along the way. We established an institutional Health Equity Network (HEN) in pursuit of excellent and equitable health outcomes for children and adolescents in our region. The HEN supports action teams seeking to eliminate pediatric health inequities in their clinical settings. Teams deploy targeted interventions to meet patients' and families' needs, addressing both medical and social factors affecting health and wellbeing. The primary, shared HEN measure is the equity gap in hospitalization rates between Black patients and all other patients. The HEN currently has 10 action teams and promotes rapid learning and scaling of interventions via monthly "action period calls" and "solutions labs" focused on successes, challenges, and potential common solutions (eg, scaling of existing medical-legal partnership to subspecialty clinics). In this Advocacy Case Study, we detail the design, implementation, and early outcomes from the HEN, our equity-oriented learning network.

Analyzing Racial Disparities in Pediatric Atopic Comorbidity Emergency Department Visitation using Electronic Health Records.

BACKGROUND: Although atopic diseases and associated co-morbidities are prevalent in children, little is known about racial differences in emergency department (ED) visitation. OBJECTIVE: We sought to examine racial differences in ED visitation among children with allergic comorbidities. METHODS: We conducted a retrospective study of patients (<21 years) who visited the ED at a large pediatric hospital for atopic dermatitis (AD), food allergy (FA), asthma, allergic rhinitis (AR), and eosinophilic esophagitis (EoE) from 2015 to 2019. We determined the probability of ED encounter-free using hazard ratios (HR) and time to recurrence (TTR) of ED encounter for patients identified as Black/African American (AA) and White/European American (EA). We assessed potentially underlying allergic, demographic, and place-based factors, and potential interactions between factors. RESULTS: A total of 30,894 patients (38% AA, 62% EA) had 83,078 ED encounters (38,378 first ED encounters, and 44,700 recurrent ED encounters) during the study period. Asthma and AR showed the highest rate of comorbidity in ED encounters in both AA and EA children. AA children exhibited higher HR for encounter following index AD and asthma encounters. We found an interaction between the type of insurance and race in ED encounters for AD, FA, AR, and EoE. In AA children, those insured by Medicaid demonstrated a higher HR for any encounter compared to those with commercial insurance. Conversely, in EA children, those with Medicaid insurance showed a lower HR compared to their commercially insured peers. Regardless of race, allergic comorbidity increased the HR of ED encounter (1.12-1.62) for all allergic diseases. At 5-years follow up, mean differences in TTR were shorter in AA children compared to EA children in AD, FA, and asthma. CONCLUSION: Identification of disease-specific racial disparities in ED visitation related to atopic diseases is a necessary first step toward the design and implementation of interventions capable of equitably reducing emergency care in atopic comorbid children.

Addressing food insecurity in the inpatient setting: Results of a postdischarge pilot study.

BACKGROUND AND OBJECTIVES: With a growing interest in screening for food insecurity (FI) during pediatric hospitalization, there is a parallel need to develop interventions. With input from caregivers experiencing FI, we sought to identify interventions to assist with short-term FI after discharge and evaluate their feasibility, acceptability, and appropriateness. METHODS: We first employed qualitative methods to identify potential interventions. Next, we conducted a pilot study of selected interventions for families experiencing FI. Seven days postdischarge, caregivers rated the intervention's feasibility, acceptability, and appropriateness. We also assessed for ongoing FI. We summarized the median and proportion of "completely agree" responses to feasibility, acceptability, and appropriateness questions, and we compared in-hospital and postdischarge FI using McNemar's test. RESULTS: In the qualitative stage, 14 caregivers prioritized three interventions: grocery store gift cards, grocery delivery/pick-up, and frozen meals. In the pilot study, 53 caregivers (25% of those screened) endorsed FI during their child's hospitalization and received one or more of the interventions. Every caregiver selected the grocery gift card option; 37 families (69.8%) also received frozen meals. Seven days after discharge, most caregivers rated the intervention as "completely" feasible (76%), acceptable (90%), and appropriate (88%). There was a significant decrease in caregivers who reported FI after discharge compared to during the hospitalization (p < .001). CONCLUSIONS: This study demonstrates the feasibility, acceptability, and appropriateness of inpatient interventions to address FI, particularly at the time of pediatric hospital discharge and transition home. Randomized trials are needed to further evaluate the efficacy of interventions employed during hospitalization.

Characterizing Inequities in Pediatric Appendicitis Delayed Diagnosis and Perforation.

Objective: We sought to characterize the impact of a child's sociodemographic characteristics on their odds of delayed diagnosis and perforation in pediatric appendicitis. Study design: We performed a single-center, retrospective cohort study of all pediatric appendicitis admissions between 2016 and 2021. Using a multivariable model, we evaluated for associations between delayed diagnosis and perforation and a child's sociodemographic characteristics, including their age, sex, race and ethnicity, insurance status, and their home census-tract Material Community Deprivation Index value. Results: The study included 3248 patients. The median age was 12.1 years (IQR 9.5-14.9 years). Most patients were male (60.3%), identified as non-Hispanic White (78.0%), and had private insurance (55.4%). The delayed diagnosis and perforation rates were 6.4% and 25.1%, respectively. Delayed diagnosis cases had a greater perforation rate (56% compared with 21.5%, P < .001). On adjusted analysis, older age decreased the odds (OR 0.91, CI 0.87-0.94) of delayed diagnosis, whereas female sex (OR 1.50, CI 1.13-2.00) and socioeconomic disadvantage (OR 1.56 for quartile 4 vs quartile 1, CI 1.00-2.43) increased the odds. Furthermore, older age (OR 0.91, CI 0.89-0.93) decreased the odds of perforation, whereas non-Hispanic Black (OR 1.72, CI 1.3-2.29) or Hispanic (OR 1.60, CI 1.24-2.08) compared with non-Hispanic White identification and socioeconomic disadvantage (OR 1.43 Q4 vs Q1, CI 1.12-1.83) increased the odds. Conclusions: Our reported delayed diagnosis rate is greater than recent literature, highlighting the need to consider visits that occur across different health care settings. We further identify sociodemographic factors, including socioeconomic status, that impact a child's risk of delayed diagnosis and perforation.

The Impact of Structural Racism on Continuity of Care at Pediatric Academic Primary Care Clinics.

OBJECTIVE: Using a structural racism framework, we assessed racial inequities in continuity of care, using the Usual Provider Continuity Index (UPC - the proportion of visits with the provider the patient saw most frequently out of all visits), in a set of large pediatric academic clinics. METHODS: We conducted a retrospective cohort study. Patients 12-24 months seen at three pediatric academic primary care clinics for any visit during October 1-31, 2021 were included. We then reviewed continuity for these patients in the preceding 12 months. Outcomes included each patient's UPC for all visits, and a modified UPC for well child checks only (UPC Well). Covariates included race, ethnicity, insurance, clinic site, age, sex, care management, or seeing a social worker. We evaluated for differences in outcomes using bivariate analyses and multivariable regression models. RESULTS: Our cohort included 356 patients (74% Black, 5% Hispanic, 85% Medicaid, 52% female, median age 15.8 months). The median UPC was 0.33 and median UPC Well was 0.40. Black patients had significantly lower median values for UPC (0.33 Black vs 0.40 non-Black, P < .01) and UPC Well (0.33 Black vs 0.50 non-Black, P < .01). There were similar inequities in continuity rates by insurance and clinic site. In multivariable models, clinic site was the only variable significantly associated with continuity. CONCLUSIONS: Clinic sites serving higher percentages of Black patients had lower rates of continuity. The main driver of racial inequities in continuity rates was at the institutional level.

Potential causes of delays in paediatric perforated appendicitis: A prospective interview study.

AIM: Delays in care may be a driver of inequities in perforated appendicitis rates. The goal of this study was to explore potential causes of delay in care for children with perforated appendicitis. METHODS: We conducted an interview study of caregivers of children admitted with perforated appendicitis to a children's hospital between December 2022 and March 2023. Semi-structured interviews based on an iteratively revised interview guide were conducted in-person during the child's admission. All interviews were transcribed, coded and underwent a process of thematic analysis. RESULTS: We reached thematic saturation after 12 interviews. The median age for children was 13.5 years, 50% were male, 83% of caregivers self-identified as White, and one interview required an interpreter. Through thematic analysis, four major themes for potential causes of delay emerged. The first theme of symptom recognition includes delays related to recognising the symptoms, their severity and the need for medical evaluation. The second theme - accessing care - describes delays that occur after a decision was made to seek care until the child was evaluated. The third theme includes delays that occur in making the diagnosis after evaluation. The last theme captures potential delays in definitive treatment after a diagnosis of appendicitis is made. CONCLUSION: We identify four major themes from the patient and family perspective, each with multiple sub-themes, for potential delays in definitive care for children with perforated appendicitis. Additional research is needed to further characterise these potential delays and quantify their role in contributing to inequities in perforation rates.

Development of a multimodal geomarker pipeline to assess the impact of social, economic, and environmental factors on pediatric health outcomes.

OBJECTIVES: We sought to create a computational pipeline for attaching geomarkers, contextual or geographic measures that influence or predict health, to electronic health records at scale, including developing a tool for matching addresses to parcels to assess the impact of housing characteristics on pediatric health. MATERIALS AND METHODS: We created a geomarker pipeline to link residential addresses from hospital admissions at Cincinnati Children's Hospital Medical Center (CCHMC) between July 2016 and June 2022 to place-based data. Linkage methods included by date of admission, geocoding to census tract, street range geocoding, and probabilistic address matching. We assessed 4 methods for probabilistic address matching. RESULTS: We characterized 124 244 hospitalizations experienced by 69 842 children admitted to CCHMC. Of the 55 684 hospitalizations with residential addresses in Hamilton County, Ohio, all were matched to 7 temporal geomarkers, 97% were matched to 79 census tract-level geomarkers and 13 point-level geomarkers, and 75% were matched to 16 parcel-level geomarkers. Parcel-level geomarkers were linked using our exact address matching tool developed using the best-performing linkage method. DISCUSSION: Our multimodal geomarker pipeline provides a reproducible framework for attaching place-based data to health data while maintaining data privacy. This framework can be applied to other populations and in other regions. We also created a tool for address matching that democratizes parcel-level data to advance precision population health efforts. CONCLUSION: We created an open framework for multimodal geomarker assessment by harmonizing and linking a set of over 100 geomarkers to hospitalization data, enabling assessment of links between geomarkers and hospital admissions.

Building a regional pediatric asthma learning health system in support of optimal, equitable outcomes.

Introduction: Asthma is characterized by preventable morbidity, cost, and inequity. We sought to build an Asthma Learning Health System (ALHS) to coordinate regional pediatric asthma improvement activities. Methods: We generated quantitative and qualitative insights pertinent to a better, more equitable care delivery system. We used electronic health record data to calculate asthma hospitalization rates for youth in our region. We completed an "environmental scan" to catalog the breadth of asthma-related efforts occurring in our children's hospital and across the region. We supplemented the scan with group-level assessments and focus groups with parents, clinicians, and community partners. We used insights from this descriptive epidemiology to inform the definition of shared aims, drivers, measures, and prototype interventions. Results: Greater Cincinnati's youth are hospitalized for asthma at a rate three times greater than the U.S. average. Black youth are hospitalized at a rate five times greater than non-Black youth. Certain neighborhoods bear the disproportionate burden of asthma morbidity. Across Cincinnati, there are many asthma-relevant activities that seek to confront this morbidity; however, efforts are largely disconnected. Qualitative insights highlighted the importance of cross-sector coordination, evidence-based acute and preventive care, healthy homes and neighborhoods, and accountability. These insights also led to a shared, regional aim: to equitably reduce asthma-related hospitalizations. Early interventions have included population-level pattern recognition, multidisciplinary asthma action huddles, and enhanced social needs screening and response. Conclusion: Learning health system methods are uniquely suited to asthma's complexity. Our nascent ALHS provides a scaffold atop which we can pursue better, more equitable regional asthma outcomes.

Causal Mediation of Neighborhood-Level Pediatric Hospitalization Inequities.

BACKGROUND AND OBJECTIVES: Population-wide racial inequities in child health outcomes are well documented. Less is known about causal pathways linking inequities and social, economic, and environmental exposures. Here, we sought to estimate the total inequities in population-level hospitalization rates and determine how much is mediated by place-based exposures and community characteristics. METHODS: We employed a population-wide, neighborhood-level study that included youth <18 years hospitalized between July 1, 2016 and June 30, 2022. We defined a causal directed acyclic graph a priori to estimate the mediating pathways by which marginalized population composition causes census tract-level hospitalization rates. We used negative binomial regression models to estimate hospitalization rate inequities and how much of these inequities were mediated indirectly through place-based social, economic, and environmental exposures. RESULTS: We analyzed 50 719 hospitalizations experienced by 28 390 patients. We calculated census tract-level hospitalization rates per 1000 children, which ranged from 10.9 to 143.0 (median 45.1; interquartile range 34.5 to 60.1) across included tracts. For every 10% increase in the marginalized population, the tract-level hospitalization rate increased by 6.2% (95% confidence interval: 4.5 to 8.0). After adjustment for tract-level community material deprivation, crime risk, English usage, housing tenure, family composition, hospital access, greenspace, traffic-related air pollution, and housing conditions, no inequity remained (0.2%, 95% confidence interval: -2.2 to 2.7). Results differed when considering subsets of asthma, type 1 diabetes, sickle cell anemia, and psychiatric disorders. CONCLUSIONS: Our findings provide additional evidence supporting structural racism as a significant root cause of inequities in child health outcomes, including outcomes at the population level.

Socioeconomic Influences on Outcomes Following Congenital Heart Disease Surgery.

Associations between social determinants of health (SDOH) and adverse outcomes for children with congenital heart disease (CHD) are starting to be recognized; however, such links remain understudied. We examined the relationship between community-level material deprivation on mortality, readmission, and length of stay (LOS) for children undergoing surgery for CHD. We performed a retrospective cohort study of patients who underwent cardiac surgery at our institution from 2015 to 2018. A community-level deprivation index (DI), a marker of community material deprivation, was generated to contextualize the lived experience of children with CHD. Generalized mixed-effects models were used to assess links between the DI and outcomes of mortality, readmission, and LOS following cardiac surgery. The DI and components were scaled to provide mean differences for a one standard deviation (SD) increase in deprivation. We identified 1,187 unique patients with surgical admissions. The median LOS was 11 days, with an overall mortality rate of 4.6% and readmission rate of 7.6%. The DI ranged from 0.08 to 0.85 with a mean of 0.37 (SD 0.12). The DI was associated with increased LOS for patients with more complex heart disease (STAT 3, 4, and 5), which persisted after adjusting for factors that could prolong LOS (all p < 0.05). The DI approached but did not meet a significant association with mortality (p = 0.0528); it was not associated with readmission (p = 0.36). Community-level deprivation is associated with increased LOS for patients undergoing cardiac surgery. Future work to identify the specific health-related social needs contributing to LOS and identify targets for intervention is needed.

Diversity, Equity, and Inclusion in Patient and Family Advisory Councils: Advancing Best Practice in Children's Hospitals.

INTRODUCTION: This qualitative research study explored practices that support and advance diverse membership in Patient and Family Advisory Councils (PFACs) in children's hospitals and the involvement of PFACs in organization-level diversity, equity, and inclusion work. METHOD: This study consisted of a focused literature review and 17 key informant interviews. The study sought to identify important learnings about (1) recruiting and supporting patient and family advisors (PFAs) from historically marginalized populations and (2) ways to develop and sustain meaningful partnerships with PFAs and PFACs in diversity, equity, and inclusion work. RESULTS: The study findings highlighted a number of best practices for hospitals to adopt, including more actively reaching out to communities served, addressing barriers to participation through approaches and structures such as specialty PFACs and "tiered" options for participation by PFAs, and co-creation of inclusive environments. DISCUSSION: To move forward with this work, additional research, true commitment from health care organizations, and shared guidance and tools for the field are needed.

Racial Inequities in Palliative Referral for Children with High-Intensity Neurologic Impairment.

OBJECTIVE: To evaluate whether racial and socioeconomic inequities in pediatric palliative care utilization extend to children with high-intensity neurologic impairment (HI-NI), which is a chronic neurological diagnosis resulting in substantial functional morbidity and mortality. STUDY DESIGN: We conducted a retrospective study of patients with HI-NI who received primary care services at a tertiary care center from 2014 through 2019. HI-NI diagnoses that warranted a palliative care referral were identified by consensus of a multidisciplinary team. The outcome was referral to palliative care. The primary exposure was race, categorized as Black or non-Black to represent the impact of anti-Black racism. Additional exposures included ethnicity (Hispanic/non-Hispanic) and insurance status (Medicaid/non-Medicaid). Descriptive statistics, bivariate analyses, and multivariable logistic regression models were performed to assess associations between exposures and palliative care referral. RESULTS: A total of 801 patients with HI-NI were included; 7.5% received a palliative referral. There were no differences in gestational age, sex, or ethnicity between patients who received a referral and those who did not. In multivariable analysis, adjusting for ethnicity, sex, gestational age, and presence of complex chronic conditions, Black children (aOR 0.47, 95% CI 0.26, 0.84) and children with Medicaid insurance (aOR 0.40, 95% CI 0.23, 0.70) each had significantly lower odds of palliative referral compared with their non-Black and non-Medicaid-insured peers, respectively. CONCLUSIONS: We identified inequities in pediatric palliative care referral among children with HI-NI by race and insurance status. Future work is needed to develop interventions, with families, aimed at promoting more equitable, antiracist systems of palliative care.

Screening for hypertension in adults: protocol for evidence reviews to inform a Canadian Task Force on Preventive Health Care guideline update.

PURPOSE: To inform updated recommendations by the Canadian Task Force on Preventive Health Care on screening in a primary care setting for hypertension in adults aged 18 years and older. This protocol outlines the scope and methods for a series of systematic reviews and one overview of reviews. METHODS: To evaluate the benefits and harms of screening for hypertension, the Task Force will rely on the relevant key questions from the 2021 United States Preventive Services Task Force systematic review. In addition, a series of reviews will be conducted to identify, appraise, and synthesize the evidence on (1) the association of blood pressure measurement methods and future cardiovascular (CVD)-related outcomes, (2) thresholds for discussions of treatment initiation, and (3) patient acceptability of hypertension screening methods. For the review of blood pressure measurement methods and future CVD-related outcomes, we will perform a de novo review and search MEDLINE, Embase, CENTRAL, and APA PsycInfo for randomized controlled trials, prospective or retrospective cohort studies, nested case-control studies, and within-arm analyses of intervention studies. For the thresholds for discussions of treatment initiation review, we will perform an overview of reviews and update results from a relevant 2019 UK NICE review. We will search MEDLINE, Embase, APA PsycInfo, and Epistemonikos for systematic reviews. For the acceptability review, we will perform a de novo systematic review and search MEDLINE, Embase, and APA PsycInfo for randomized controlled trials, controlled clinical trials, and observational studies with comparison groups. Websites of relevant organizations, gray literature sources, and the reference lists of included studies and reviews will be hand-searched. Title and abstract screening will be completed by two independent reviewers. Full-text screening, data extraction, risk-of-bias assessment, and GRADE (Grading of Recommendations Assessment, Development and Evaluation) will be completed independently by two reviewers. Results from included studies will be synthesized narratively and pooled via meta-analysis when appropriate. The GRADE approach will be used to assess the certainty of evidence for outcomes. DISCUSSION: The results of the evidence reviews will be used to inform Canadian recommendations on screening for hypertension in adults aged 18 years and older. SYSTEMATIC REVIEW REGISTRATION: This protocol is registered on PROSPERO and is available on the Open Science Framework (osf.io/8w4tz).

Learning from an equitable, data-informed response to COVID-19: Translating knowledge into future action and preparation.

Introduction: The COVID-19 pandemic revealed numerous barriers to effectively managing public health crises, including difficulties in using publicly available, community-level data to create learning systems in support of local public health decision responses. Early in the COVID-19 pandemic, a group of health care partners began meeting to learn from their collective experiences. We identified key tools and processes for using data and learning system structures to drive equitable public health decision making throughout different phases of the pandemic. Methods: In fall of 2021, the team developed an initial theory of change directed at achieving herd immunity for COVID-19. The theoretical drivers were explored qualitatively through a series of nine 45-min telephonic interviews conducted with 16 public health and community leaders across the United States. Interview responses were analyzed into key themes to inform potential future practices, tools, and systems. In addition to the interviews, partners in Dallas and Cincinnati reflected on their own COVID-19 experiences. Results: Interview responses fell broadly into four themes that contribute to effective, community driven responses to COVID-19: real-time, accessible data that are mindful of the tension between community transparency and individual privacy; a continued fostering of public trust; adaptable infrastructures and systems; and creating cohesive community coalitions with shared alignment and goals. These themes and partner experiences helped us revise our preliminary theory of change around the importance of community collaboration and trust building and also helped refine the development of the Community Protection Dashboard tool. Conclusions: There was broad agreement amongst public health and community leaders about the key elements of the data and learning systems required to manage public health responses to COVID-19. These findings may be informative for guiding the use of data and learning in the management of future public health crises or population health initiatives.
