The development of a performance evaluation index system for Chinese Centers for Disease Control and Prevention: a Delphi consensus study

BackgroundThe performance evaluation of the Centers for Disease Control and Prevention (CDC) is crucial for enhancing the quality of public health services. With the ongoing reform of the CDC system in China, the existing performance evaluation system faces challenges. This study used the Delphi method to develop a new performance evaluation system for China’s provincial, city, and county-level CDC.MethodsFollowing the “Structure-Process-Outcome” model, assessment indicators were systematically collected. Indicators were modified and screened through two Delphi rounds based on CDC responsibilities, health development, and national policies. Twenty-four experts provided ratings and recommendations, and the research team evaluated questionnaire reliability, expert positivity, expert authority, and opinion consistency.ResultsThe preliminary index system identified through the literature review and pre-survey included 11 primary, 30 secondary, and 64 tertiary indicators. After the first round of consultation, two secondary indicators and 11 tertiary indicators were removed and 22 tertiary indicators were added. After the second round of consultation, three secondary indicators and 11 tertiary indicators were removed and three tertiary indicators were added, at which point the p-value of the test for Kendall’s coefficient of concordance W was < 0.001 and the coefficient of variation was within acceptable limits (< 0.25), so the consultation was concluded. The final index system included 11 primary, 25 secondary, and 67 tertiary indicators.ConclusionsThis study responded to the CDC system reform by developing a comprehensive performance evaluation index system for provincial, city, and county-level CDC in China. The index system is both scientifically grounded and practical, serving as an effective tool for promoting the high-quality work of CDC organizations.

Safety of Antiretroviral Exposure during Pregnancy: Opportunities to Close Data Gaps

Abstract Pregnant persons with chronic health conditions often require pharmacotherapy to remain healthy. The Antiretroviral Pregnancy Registry is a prospective, international, voluntary, and exposure registry that collects information on antiretroviral exposure; however, a minority of providers utilize the registry, leaving critical gaps to guide prescribing in this population. The Task Force for the Elimination of Perinatal HIV Transmission in the United States, funded by the Centers for Disease Control and Prevention, has identified the monitoring of antiretroviral safety as a paramount concern in the ongoing mission to eliminate perinatal HIV transmission. As active members of this Task Force, we urge all healthcare providers who care for pregnant individuals to prioritize reporting all antiretroviral exposures to the registry.

The Hand, Foot, and Mouth Disease Sentinel Surveillance System in South Korea: Retrospective Evaluation Study.

South Korea has implemented a hand, foot, and mouth disease (HFMD) surveillance system since 2009 to monitor incidence trends and identify disease burden. This nationwide surveillance involves a network of approximately 100 pediatric clinics that report all probable and confirmed HFMD cases. Following the COVID-19 pandemic, infectious disease surveillance systems must be evaluated to ensure the effective use of limited public health resources. This study aimed to evaluate the HFMD sentinel surveillance system in South Korea from 2017 to 2022, focusing on the transition period after the COVID-19 pandemic. We retrospectively reviewed the HFMD sentinel surveillance system from the Korea Disease Control and Prevention Agency using systematic guidelines for public health surveillance system evaluation developed by the US Centers for Disease Control and Prevention. We assessed the system's overall performance in 5 main factors: timeliness, stability, completeness, sensitivity, and representativeness (ie, the age and geographic distribution of sentinels). We rated these factors as weak, moderate, or good. Our study showed that the completeness, sensitivity, and age representativeness of the HFMD surveillance performance were temporarily reduced to moderate levels from 2020 to 2021 and recovered in 2022, while the timeliness and geographic representativeness were maintained at a good level throughout the study period. The stability of the surveillance was moderate from 2017 to 2021 and weak in 2022. This is the first study to evaluate the HFMD surveillance system after the acute phase of the COVID-19 pandemic. We identified a temporarily reduced level of performance (ie, completeness, sensitivity, and age-specific representativeness) during the acute phase of the pandemic and good performance in 2022. Surveillance system evaluation and maintenance during public health emergencies will provide robust and reliable data to support public health policy development. Regular staff training programs and reducing staff turnover will improve HFMD surveillance system stability.

Summary of the Centers for Disease Control and Prevention's Self-reported Traumatic Brain Injury Survey Efforts.

Surveillance of traumatic brain injury (TBI), including concussion, in the United States has historically relied on healthcare administrative datasets, but these methods likely underestimate the true burden of TBI. The Centers for Disease Control and Prevention (CDC) has recently added TBI prevalence questions to several national surveys. The objective of this article is to summarize their recent efforts and report TBI prevalence estimates. Surveys. Adult and youth respondents to a series of national surveys. Recent nationally representative surveys with either 12-month or lifetime TBI prevalence questions were identified. For each data source, survey methodology, TBI definition, question wording, and prevalence estimates were examined. TBI prevalence varied depending on the question wording and data source. Overall 12-month prevalence of concussion/TBI among adults ranged from 2% to 12% while overall lifetime prevalence of concussion or TBI ranged from 19% to 29%. Overall 12-month prevalence of concussion/TBI among children and adolescents was 10% while 12-month prevalence of sports- and recreation-related concussion for youth ranged from 7% to 15%. Overall lifetime prevalence of TBI among youth ranged from 6% to 14%. Survey data based on self-reported concussions and TBIs resulted in larger prevalence estimates than would be expected based on traditional surveillance methods. Analyses of the various surveys shows that how the questions are asked and what terminology is used can notably affect the estimates observed. Efforts can be made to optimize and standardize data collection approaches to ensure consistent measurement across settings and populations.

A Randomized, Placebo-Controlled Trial to Evaluate the Safety and Efficacy of VIR-2482 in Healthy Adults for Prevention of Influenza A Illness (PENINSULA).

Influenza A results in significant morbidity and mortality. VIR-2482, an engineered human monoclonal antibody with extended half-life, targets a highly conserved epitope on the stem region of influenza A hemagglutinin, and may protect against seasonal and pandemic influenza. This double-blind, randomized, placebo-controlled, phase 2 study examined the safety and efficacy of VIR-2482 for seasonal influenza A illness prevention in unvaccinated healthy adults. Participants (N = 2977) were randomized 1:1:1 to receive VIR-2482 450 mg, VIR-2482 1200 mg, or placebo via intramuscular (IM) injection. Primary and secondary efficacy endpoints were the proportions of participants with reverse transcriptase-polymerase chain reaction (RT-PCR)-confirmed influenza A infection and either protocol-defined influenza-like illness (ILI) and Centers for Disease Control and Prevention (CDC)-defined ILI or World Health Organization (WHO)-defined ILI, respectively. VIR-2482 450 mg and 1200 mg prophylaxis did not reduce the risk of protocol-defined ILI with RT-PCR-confirmed influenza A versus placebo (relative risk reduction [RRR], 3.8% [95% CI: -67.3, 44.6] and 15.9% [95% CI: -49.3, 52.3], respectively). At the 1200 mg dose, the RRRs in influenza A illness were 57.2% [95% CI: -2.5, 82.2] using CDC-ILI and 44.1% [95% CI: -50.5, 79.3] using WHO-ILI definitions, respectively. Serum VIR-2482 levels were similar regardless of influenza status; variants with reduced VIR-2482 susceptibility were not detected. Local injection-site reactions were mild and similar across groups. VIR-2482 1200 mg IM was well tolerated but did not significantly prevent protocol-defined ILI. Secondary endpoint analyses suggest this dose may have reduced influenza A illness.

"By Us for Us": Lessons Learned in Developing a National Training and Technical Assistance Center by and for CHWs.

In 2021, the Centers for Disease Control and Prevention (CDC) funded 67 health departments to implement community health worker (CHW) programs to enhance COVID-19 response. The CDC also funded a unique CHW-led Technical Assistance and Training (TTA) Center called Envision, which supported health departments to implement CHW programs and promote CHW workforce sustainability. After 1 year, Envision evaluators interviewed Envision staff to assess barriers and facilitators in developing the Center and the degree to which CHW leadership was operationalized. Thematic analysis revealed 3 themes regarding relationships, CHW values in practice, and operational challenges. Findings informed program updates. CHWs, funders, and policymakers may learn from these experiences.

Evaluating the delivery of care by telemedicine for incarcerated people living with HIV: a cohort study

BackgroundThe use of telemedicine has grown significantly since the COVID-19 pandemic and has the potential to improve access to specialized care for otherwise underserved populations. Incarcerated people living with HIV (PLWH) could potentially benefit from expanded access to HIV care through telemedicine.MethodsAll PLWH who were incarcerated within the Tennessee Department of Corrections and received care through the HIV telemedicine clinic at Regional One Hospital between 5/1/2019 through 2/28/2022 were identified from the electronic health records (EHR). Demographics, laboratory data, vaccine history, and treatment outcomes were abstracted from the EHR. Retention in care and viral suppression were defined using Centers for Disease Control and Prevention definitions.ResultsOf the 283 incarcerated PLWH receiving care from this telemedicine clinic, 78% remained retained in care and 94% achieved or maintaining viral suppression at 12 months. Many preventative care measures remained unperformed or undocumented, including vaccinations and testing for concurrent sexually transmitted infections. There were 56 patients (20%) found to have chronic hepatitis C in this population, with 71% either cured or still on treatment in this study period.ConclusionsRetention in care and viral suppression rates were excellent among incarcerated PLWH receiving telemedicine care for their HIV. HIV related primary health care screenings and vaccinations, however, were less consistently documented and represent areas for improvement.

Validation of Contrast-Enhanced Mammography as Breast Imaging Modality Compared to Standard Mammography and Digital Breast Tomosynthesis.

Contrast-enhanced mammography (CEM) is a relatively new imaging technique that allows morphologic, anatomic and functional imaging of the breast. The aim of our study was to validate contrast-enhanced mammography (CEM) compared to mammography (MMG) and digital breast tomosynthesis (DBT) in daily clinical practice. This retrospective study included 316 consecutive patients who underwent MMG, DBT and CEM at the Centre for Prevention and Diagnosis of Chronic Diseases of Primorsko-goranska County. Two breast radiologists independently analyzed the image data, without available anamnestic information and without the possibility of comparison with previous images, to determine the presence of suspicious lesions and their morphological features according to the established criteria of the Breast Imaging Reporting and Data System (BI-RADS) lexicon. The diagnostic value of MMG, DBT and CEM was assessed by ROC analysis. The interobserver agreement was excellent. CEM showed higher diagnostic accuracy in terms of sensitivity and specificity compared to MMG and DBT, the reporting time for CEM was significantly shorter, and CEM findings resulted in a significantly lower proportion of equivocal findings (BI-RADS 0), suggesting fewer additional procedures. In conclusion, CEM achieves high diagnostic accuracy while maintaining simplicity, reproducibility and applicability in complex clinical settings.

Evaluation of the Centers for Disease Control and Prevention's Essentials for Parenting Toddlers and Preschoolers on parent behavioral outcomes

BackgroundThe Centers for Disease Control and Prevention's web-based behavioral parent training (BPT) program, Essentials for Parenting Toddlers and Preschoolers (EfP), uses a psychoeducational approach to promote positive parenting and address common parenting challenges. The purpose of this study was to assess the effects of EfP on parenting behavior and whether implementation format impacted behavioral outcomes. MethodsA sample of 200 parents of 2- to 4-year-old children were recruited via Internet advertising. Using a repeated single subject, multiple baseline design, parents were randomly assigned to guided navigation (GN; n = 100) or unguided navigation (UN; n = 100) study conditions. Parents were provided secure access to the EfP website and completed 18 weekly surveys. Latent growth curve modeling was used to determine intervention effectiveness on behavioral outcomes. ResultsLatent growth curve modeling indicated both GN and UN study conditions significantly increased use of praise (β = 0.19, p = 0.038) and commands and consequences (β = 0.17, p < 0.001), and decreased corporal punishment use (β = −0.01, p = 0.017) and attitudes promoting corporal punishment (β = −0.01, p < 0.001) over the study period. The UN condition exhibited a significant initial decrease in time-out use that increased over time to match the GN condition. ConclusionsThis study provides evidence for the effectiveness of EfP in promoting non-violent parenting behavior and increasing positive parenting techniques. The format of EfP implementation made no difference in parenting behaviors over time. Digital BPT programs like EfP provide access to evidence-informed parenting resources and can enhance positive parenting.

The Impact of the Communities that Care Approach in Reducing Violence and Crime Within an Urban, High-Burden Community.

Community violence and crime are significant public health problems with serious and lasting effects on young people, families, and communities. This violence and crime have significant ripple effects, affecting not just those who are directly physically injured, but also those who witness violent episodes, those who have friends or loved ones killed or injured, and those who must everyday navigate streets that they know have been frequent sites of serious violence and crime. The current study presents evidence of the impact that a data-driven, collective impact approach - the Communities that Care prevention system - can have on violence and crime outcomes within a large urban, high-burden community. Established as one of the national Youth Violence Prevention Centers (YVPC) funded by the Centers for Disease Control and Prevention, the Chicago Center for Youth Violence Prevention is among the first to implement the CTC approach in a large, urban community. The current study's findings show reductions in violence (i.e., aggravated assaults and robberies) in the Bronzeville community, compared to similar communities in Chicago.

CDC's Laboratory Activities to Support Newborn Screening for Spinal Muscular Atrophy.

Spinal muscular atrophy (SMA) was added to the HHS Secretary's Recommended Uniform Screening Panel for newborn screening (NBS) in 2018, enabling early diagnosis and treatment of impacted infants to prevent irreversible motor neuron damage. In anticipation of supporting SMA newborn screening, scientists at the U.S. Centers for Disease Control and Prevention (CDC) have worked towards building resources for public health laboratories in four phases since 2013. In Phase 1, CDC established a real-time PCR assay, which uses a locked nucleic acid probe to attain the needed specificity, to detect SMN1 exon 7. In Phase 2, we developed quality assurance dried blood spot materials made with transduced lymphoblast cell lines established from de-identified SMA patients, carriers, and unaffected donors. In 2021, CDC implemented Phase 3, a proficiency testing program, that now supports 115 NBS labs around the world. We are currently completing Phase 4, which includes the implementation of an external SMA quality control material program. Also, during this time, CDC has provided individual technical assistance to NBS programs and bench training to NBS scientists during our annual molecular workshop. These CDC-led activities have contributed to the rapid and full implementation of SMA screening in all 50 U.S. states as of February 2024.

Neurological manifestations of ehrlichiosis among a cohort of patients: prevalence and clinical symptoms

BackgroundEhrlichiosis is a potentially fatal tick-borne disease that can progress to involve the central nervous system (CNS) (i.e., neuro-ehrlichiosis), particularly in cases where diagnosis and treatment are delayed. Despite a six-fold national increase in the incidence of ehrlichiosis over the past 20 years, recent data on the prevalence and manifestations of neuro-ehrlichiosis are lacking.MethodsWe conducted a retrospective chart review of all patients tested for ehrlichiosis at University of North Carolina Health facilities between 2018 and 2021 and identified patients who met epidemiological criteria for ehrlichiosis as established by the Council of State and Territorial Epidemiologists and employed by the Centers for Disease Control and Prevention. We estimated the prevalence of neurological symptoms and described the spectrum of neurological manifestations in acute ehrlichiosis, documenting select patient cases in more detail in a case series.ResultsOut of 55 patients with confirmed or probable ehrlichiosis, five patients (9.1%) had neurologic symptoms, which is notably lower than previous estimates. Neurological presentations were highly variable and included confusion, amnesia, seizures, focal neurological deficits mimicking ischemic vascular events, and an isolated cranial nerve palsy, though all patients had unremarkable neuroimaging at time of presentation. All but one patient had risk factors for severe ehrlichiosis (i.e., older age, immunosuppression).ConclusionsNeuro-ehrlichiosis may lack unifying patterns in clinical presentation that would otherwise aid in diagnosis. Clinicians should maintain a high index of suspicion for neuro-ehrlichiosis in patients with acute febrile illness, diverse neurological symptoms, and negative neuroimaging in lone star tick endemic regions.

Interactions Between Forced Sexual Intercourse Victimization and Gender on Violent Behaviors: Youth Risk Behavior Survey 2017-2019.

In recent years, the United States has seen an increase in gun-related violence and school shootings. The Centers for Disease Control and Prevention (CDC) estimates that the incidence of gun carrying among high-school students has declined. Nevertheless, an examination of the underlying factors that increase the risk of violence-related behaviors is necessary to develop interventions to decrease gun use among high-school students. General Strain Theory (GST) predicts that victims of violence are (a) significantly more likely to engage in violent behaviors and (b) the increased risk of violent behavior by persons who experience violence is significantly greater among male victims. This research aims to test these predictions of the strain theory with data from the Youth Risk Behavior Survey (YRBS). To that end, it investigates whether the relationship between forced sexual intercourse victimization (FSIV) and gun or weapon carrying or physical fighting is significantly greater among male students. Using R and pooled data from the nationally representative YRBS (2017 and 2019), additive interactions were estimated according to Strengthening the Reporting of Observational Studies in Epidemiology guidelines to determine the association between FSIV and weapon carry, gun carry, or physical fighting. Multiplicative interactions and odds ratios were also estimated for comparison. Results show a high risk of gun and weapon carrying and physical fighting among both male and female students who experience FSIV and a significant relationship between FSIV and increased risk of these violence-related behaviors. Additive interactions show that the relationship between FSIV and these violent behaviors is each significantly greater among male students than female students. Results confirm the predictions of GST and show that FSIV significantly increases the risk of gun carrying and other violence-related behaviors among male and female U.S. high-school students; the increased risk is significantly greater among male students.

Synthetic datasets for open software development in rare disease research

BackgroundGlobally, researchers are working on projects aiming to enhance the availability of data for rare disease research. While data sharing remains critical, developing suitable methods is challenging due to the specific sensitivity and uniqueness of rare disease data. This creates a dilemma, as there is a lack of both methods and necessary data to create appropriate approaches initially. This work contributes to bridging this gap by providing synthetic datasets that can form the foundation for such developments.MethodsUsing a hierarchical data generation approach parameterised with publicly available statistics, we generated datasets reflecting a random sample of rare disease patients from the United States (US) population. General demographics were obtained from the US Census Bureau, while information on disease prevalence, initial diagnosis, survival rates as well as race and sex ratios were obtained from the information provided by the US Centers for Disease Control and Prevention as well as the scientific literature. The software, which we have named SynthMD, was implemented in Python as open source using libraries such as Faker for generating individual data points.ResultsWe generated three datasets focusing on three specific rare diseases with broad impact on US citizens, as well as differences in affected genders and racial groups: Sickle Cell Disease, Cystic Fibrosis, and Duchenne Muscular Dystrophy. We present the statistics used to generate the datasets and study the statistical properties of output data. The datasets, as well as the code used to generate them, are available as Open Data and Open Source Software.ConclusionThe results of our work can serve as a starting point for researchers and developers working on methods and platforms that aim to improve the availability of rare disease data. Potential applications include using the datasets for testing purposes during the implementation of information systems or tailored privacy-enhancing technologies.

An investigation of an outbreak of Salmonella Typhimurium infections linked to cantaloupe – United States, 2022

In 2022, the Food and Drug Administration (FDA), the Centers for Disease Control and Prevention (CDC), and state health and regulatory partners investigated an outbreak of Salmonella enterica serovar Typhimurium infections linked to cantaloupes from southwest Indiana, resulting in 87 ill persons and 32 hospitalizations reported in 11 states. Epidemiologic and traceback evidence confirmed cantaloupe as the vehicle for these infections. Based on records collected by FDA, traceback of cantaloupe exposures for 14 ill people converged on a packing house in southwest Indiana, which supplied cantaloupe to eight of the 11 points of service where ill people purchased cantaloupe. Salmonella isolates were recovered from environmental samples collected by FDA from three growers and a packing house in southwest Indiana. Whole genome sequencing analyses of these isolates found that isolates collected from one grower matched the Salmonella Typhimurium outbreak strain, and samples collected from the other two growers and the packing house matched a 2020 Salmonella Newport outbreak strain. State and federal public health and agricultural partners identified potential conditions and practices that could have possibly resulted in the contamination of cantaloupe, including the presence of Salmonella spp. in on-farm, post-harvest, and off-farm environments. This is the third outbreak of salmonellosis confirmed to be linked to melons, sourced from southwest Indiana in the last decade. The 2012, 2020, and 2022 outbreaks of reoccurring and persisting strains of Salmonella illustrate the need for additional efforts to determine the source and extent of environmental contamination in the melon growing region of southwest Indiana and for outreach and education to help promote practices to reduce contamination of melons.

Adverse Events of COVID-19 Vaccines in the United States: Temporal and Spatial Analysis.

The COVID-19 pandemic, caused by SARS-CoV-2, has had a profound impact worldwide, leading to widespread morbidity and mortality. Vaccination against COVID-19 is a critical tool in controlling the spread of the virus and reducing the severity of the disease. However, the rapid development and deployment of COVID-19 vaccines have raised concerns about potential adverse events following immunization (AEFIs). Understanding the temporal and spatial patterns of these AEFIs is crucial for an effective public health response and vaccine safety monitoring. This study aimed to analyze the temporal and spatial characteristics of AEFIs associated with COVID-19 vaccines in the United States reported to the Vaccine Adverse Event Reporting System (VAERS), thereby providing insights into the patterns and distributions of the AEFIs, the safety profile of COVID-19 vaccines, and potential risk factors associated with the AEFIs. We conducted a retrospective analysis of administration data from the Centers for Disease Control and Prevention (n=663,822,575) and reports from the surveillance system VAERS (n=900,522) between 2020 and 2022. To gain a broader understanding of postvaccination AEFIs reported, we categorized them into system organ classes (SOCs) according to the Medical Dictionary for Regulatory Activities. Additionally, we performed temporal analysis to examine the trends of AEFIs in all VAERS reports, those related to Pfizer-BioNTech and Moderna, and the top 10 AEFI trends in serious reports. We also compared the similarity of symptoms across various regions within the United States. Our findings revealed that the most frequently reported symptoms following COVID-19 vaccination were headache (n=141,186, 15.68%), pyrexia (n=122,120, 13.56%), and fatigue (n=121,910, 13.54%). The most common symptom combination was chills and pyrexia (n=56,954, 6.32%). Initially, general disorders and administration site conditions (SOC 22) were the most prevalent class reported. Moderna exhibited a higher reporting rate of AEFIs compared to Pfizer-BioNTech. Over time, we observed a decreasing reporting rate of AEFIs associated with COVID-19 vaccines. In addition, the overall rates of AEFIs between the Pfizer-BioNTech and Moderna vaccines were comparable. In terms of spatial analysis, the middle and north regions of the United States displayed a higher reporting rate of AEFIs associated with COVID-19 vaccines, while the southeast and south-central regions showed notable similarity in symptoms reported. This study provides valuable insights into the temporal and spatial patterns of AEFIs associated with COVID-19 vaccines in the United States. The findings underscore the critical need for increasing vaccination coverage, as well as ongoing surveillance and monitoring of AEFIs. Implementing targeted monitoring programs can facilitate the effective and efficient management of AEFIs, enhancing public confidence in future COVID-19 vaccine campaigns.

Development of Interoperable Computable Phenotype Algorithms for Adverse Events of Special Interest to Be Used for Biologics Safety Surveillance: Validation Study.

Adverse events associated with vaccination have been evaluated by epidemiological studies and more recently have gained additional attention with the emergency use authorization of several COVID-19 vaccines. As part of its responsibility to conduct postmarket surveillance, the US Food and Drug Administration continues to monitor several adverse events of special interest (AESIs) to ensure vaccine safety, including for COVID-19. This study is part of the Biologics Effectiveness and Safety Initiative, which aims to improve the Food and Drug Administration's postmarket surveillance capabilities while minimizing public burden. This study aimed to enhance active surveillance efforts through a rules-based, computable phenotype algorithm to identify 5 AESIs being monitored by the Center for Disease Control and Prevention for COVID-19 or other vaccines: anaphylaxis, Guillain-Barré syndrome, myocarditis/pericarditis, thrombosis with thrombocytopenia syndrome, and febrile seizure. This study examined whether these phenotypes have sufficiently high positive predictive value (PPV) to ensure that the cases selected for surveillance are reasonably likely to be a postbiologic adverse event. This allows patient privacy, and security concerns for the data sharing of patients who had nonadverse events can be properly accounted for when evaluating the cost-benefit aspect of our approach. AESI phenotype algorithms were developed to apply to electronic health record data at health provider organizations across the country by querying for standard and interoperable codes. The codes queried in the rules represent symptoms, diagnoses, or treatments of the AESI sourced from published case definitions and input from clinicians. To validate the performance of the algorithms, we applied them to electronic health record data from a US academic health system and provided a sample of cases for clinicians to evaluate. Performance was assessed using PPV. With a PPV of 93.3%, our anaphylaxis algorithm performed the best. The PPVs for our febrile seizure, myocarditis/pericarditis, thrombocytopenia syndrome, and Guillain-Barré syndrome algorithms were 89%, 83.5%, 70.2%, and 47.2%, respectively. Given our algorithm design and performance, our results support continued research into using interoperable algorithms for widespread AESI postmarket detection.

Veteran's Health Administration HIV Care Continuum: 2019 vs 2022.

The diagnosis-based Human Immunodeficiency Virus (HIV) Care Continuum offers a well-established framework for measuring HIV care quality. It is used by the government agencies, community organizations, and health care institutions to "guide the nation's response to HIV" and assesses HIV care from the time of HIV diagnosis through viral suppression. Our objective is to present the Veteran Health Administration's (VHA) HIV Care Continuum, assess postpandemic versus prepandemic performance, and compare VHA performance to Centers for Disease Control and Prevention-published data. We conducted a nationwide retrospective cohort analysis examining the care continuum for people with HIV (PWH) in VHA care in 2019 versus 2022. Measurements included linkage to care, receipt of care, retention in care, and viral suppression. We used multivariable logistic regression of virological suppression to identify factors associated with viral suppression. In VHA in 2019, 83% of individuals newly diagnosed with HIV were linked to care, 84% of PWH received care, 76% were retained in care, and viral suppression was 76% among those with HIV and 93% of those with viral load (VL) results. In 2022, 74% were linked to care, 79% received care, 67% were retained in care, and viral suppression was 70% among those with HIV and 94% of those with a VL result. VHA has achieved >90% viral suppression among those with a VL result. Among all PWH, viral suppression decreased an absolute 5.2% between 2019 and 2022. VHA's performance on the HIV Care Continuum exceeds the national HIV Care Continuum reported by the Centers for Disease Control and Prevention.

A Framework for Response Escalation and Emergency Response Asset Management.

The Centers for Disease Control and Prevention (CDC) responds to public health emergencies at various levels within its organization. Overtime, CDC's response capabilities have matured across the organization due to years of emergency management investment and experience across the agency. In 2019, CDC began to implement the Graduated Response Framework to formalize an approach for managing public health emergencies that recognizes its response capabilities and meets the evolving needs of the country. This brief report summarizes CDC's Graduated Response Framework structure, and how response management escalates and de-escalates according to resource needs and complexity.

Building Partnerships Out of Barriers: Lessons Learned From Partnerships Between Centers for Independent Living and Health Departments During the COVID-19 Pandemic.

People with disabilities were left behind in the beginning of the COVID-19 vaccination rollout. More work needs to be done to connect people with disabilities to public health initiatives. Centers for Independent Living (CILs) are an important and under-utilized community partner for health departments and should be engaged as a trusted source when working to reach people with disabilities and improve access to public health programs and services. The National Foundation for the Centers for Disease Control and Prevention (CDC Foundation), through funding from the CDC, launched the Leveraging CILs to Increase Vaccine Access for People with Disabilities project. The primary goal was to increase accessibility of the COVID-19 vaccination among people with disabilities through (1) outreach and education, (2) service linkage and barrier removal through increasing accessible, (3) widespread education about the vaccine, and (4) improved partnerships between disability-led organizations and local health care providers. A grant program resulted in 39 awards distributed to CILs across the United States totaling $2 955 294.00 between November 2021 and March 2023. The project successfully resulted in reported improvements in partnerships between funded CILs and local health providers and a reported reduction in barriers to accessing vaccinations faced by people with disabilities. A suite of resources was also created to address targeted needs identified throughout partner implementation. Successful outreach to the targeted population resulted in 27 044 consumers being directly reached by CILs and 3 675 655 people reached through communication and outreach activities. Catalytic funding to disability-led organizations during public health emergency response and including people with disabilities as subject matter experts in program design can successfully strengthen access to care via trust building, message dissemination, and partnership. Building the capacity of community-based and consumer-led partners to implement evidence-based public health programming can provide a foundation for improved care for people with disabilities, particularly during an emergency response.
