RESUMO

BACKGROUND: Primary care and frontline healthcare providers are often the first point of contact for patients experiencing tick-borne disease (TBD) but face challenges when recognizing and diagnosing these diseases. The specific aim of this study was to gain a qualitative understanding of frontline and primary care providers' knowledge and practices for identifying TBDs in patients. METHODS: From fall 2018 to spring 2019, three focus groups were conducted with primary care providers practicing in a small-town community endemic to Lyme disease (LD) and with emerging incidence of additional TBDs. A follow up online survey was distributed to urgent and emergency care providers in the small-town community and an academic medical center within the referral network of the local clinical community in spring and summer 2019. Qualitative analysis of focus group data was performed following a grounded theory approach and survey responses were analyzed through the calculation of descriptive statistics. RESULTS: Fourteen clinicians from three primary care practices participated in focus groups, and 24 urgent and emergency care clinicians completed the survey questionnaire. Four overarching themes emerged from focus group data which were corroborated by survey data. Themes highlighted a moderate level of awareness on diagnosis and treatment of LD among participants and limited knowledge of diagnosis and treatment for two other regionally relevant TBDs, anaplasmosis and babesiosis. Providers described challenges and frustrations in counseling patients with strong preconceptions of LD diagnosis and treatment in the context of chronic infection. Providers desired additional point-of-care resources to facilitate patient education and correct misinformation on the diagnosis and treatment of TBDs. CONCLUSIONS: Through this small study, it appears that clinicians in the small-town and academic medical center settings are experiencing uncertainties related to TBD recognition, diagnosis, and patient communication. These findings can inform the development of point-of-care resources to aid in patient-provider communication regarding TBDs and inform the development of continuing medical education programs for frontline and primary care providers.

RESUMO

BACKGROUND: Active surveillance is a management strategy for men diagnosed with early-stage, low-risk prostate cancer in which their cancer is monitored and treatment is delayed. This study investigated the primary coping mechanisms for men following the active surveillance treatment plan, with a specific focus on how these men interact with their social network as they negotiate the stress and uncertainty of their diagnosis and treatment approach. METHODS: Thematic analysis of semi-structured interviews at two academic institutions located in the northeastern US. Participants include 15 men diagnosed with low-risk prostate cancer following active surveillance. RESULTS: The decision to follow active surveillance reflects the desire to avoid potentially life-altering side effects associated with active treatment options. Men on active surveillance cope with their prostate cancer diagnosis by both maintaining a sense of control over their daily lives, as well as relying on the support provided them by their social networks and the medical community. Social networks support men on active surveillance by encouraging lifestyle changes and serving as a resource to discuss and ease cancer-related stress. CONCLUSIONS: Support systems for men with low-risk prostate cancer do not always interface directly with the medical community. Spousal and social support play important roles in helping men understand and accept their prostate cancer diagnosis and chosen care plan. It may be beneficial to highlight the role of social support in interventions targeting the psychosocial health of men on active surveillance.

RESUMO

BACKGROUND: The Millennium Development Goals (MDGs) are 8 international development goals voluntarily adopted by 189 nations. The goals included health related aims to reduce the under-five child mortality rate by two-thirds (MDG4), and to reduce the maternal mortality ratio by three-quarters (MDG5). To assess the relationship between the healthcare workforce and MDGs 4-5, we examined the physician workforces of countries around the globe, in terms of the Physician Density Level (PDL, or number of physicians per 1000 population), and compared this rate across a number of years to several indicator variables specified as markers of progress towards MDG4 and MDG5. METHODS: Data for each variable of interest were obtained from the World Bank's Millennium Development Goals and World Development Indicators databases for 208 countries and territories from 2004 to 2014, representing a ten-year period for which the most information is available. We analyzed the relationships between MDG outcomes and PDL, controlling for national income levels and other covariates, using linear mixed model regression. Dependent variables were logarithmically transformed to meet assumptions necessary for multivariate analysis. RESULTS: In unadjusted models, an increase of every one physician per 1000 population (one unit change in PDL) lowered the risk of not being vaccinated for measles-mumps-rubella (MMR) to 29.3% (p < 0.001, 95% CI: 22.2%-38.7%) and for not receiving diphtheria-tetanus-pertussis (DTaP) vaccination rate decreased to 38.5% (p < 0.001, 95% CI: 28.7% - 51.7%). Maternal mortality rate decreased to 76.6% (p < 0.001, 95% CI: 74.3% - 79.0%), neonatal mortality decreased to 58.8% (p < 0.001, 95% CI: 54.8% - 63.2%) and under-5 mortality rate decreased to 52.1% (p < 0.001, 95% CI: 48.0% - 56.4%), with every one-unit change in PDL. Adjusted models tended to reflect unadjusted risk assessments. CONCLUSION: The maintenance and improvement of the health workforce is a vital consideration when assessing how to achieve global development goals related to health outcomes.

RESUMO

CONTEXT: Tobacco use remains the leading cause of preventable death in the United States. States and municipalities have instituted a variety of tobacco control measures (TCMs) to address the significant impact tobacco use has on population health. The American Lung Association annually grades state performance of tobacco control using the State of Tobacco Control grading framework. OBJECTIVE: To gain an updated understanding of how recent efforts in tobacco control have impacted tobacco use across the United States, using yearly State of Tobacco Control TCM assessments. DESIGN: The independent TCM variables of smoke-free air score, cessation score, excise tax, and percentage of recommended funding were selected from the American Lung Association State of Tobacco Control reports. Predictors of adult smoking rates were determined by a mixed-effects model. SETTING/PARTICIPANTS: The 50 US states and District of Columbia. MAIN OUTCOME MEASURE: Adult smoking rate in each state from 2011 to 2013. RESULTS: The average adult smoking rate decreased significantly from 2011 to 2013 (21.3% [SD: 3.5] to 19.3% [SD: 3.5], P = .016). All forms of TCMs varied widely in implementation levels across states. Excise taxes (ß = -.812, P = .006) and smoke-free air regulations (ß = -.057, P = .008) were significant, negative predictors of adult smoking. Cessation services (ß = .015, P = .46) did not have a measurable effect on adult smoking. CONCLUSION: Tobacco control measures with the strongest influence on adult smoking include the state excise tax and state smoke-free air regulations. The lack of robust funding for tobacco cessation services across the majority of US states highlights an important shortfall in current tobacco control policy.

RESUMO

INTRODUCTION: Attracting and retaining healthcare providers in rural locations in the USA has been an issue for more than two decades. In response to this need, many health sciences education institutions in the USA have developed special programs to encourage students to become healthcare providers in rural locations. One approach is the use of community-based education experiences through rural track programs. Rural track programs seek to address the shortage of healthcare providers working in rural areas by nurturing and educating students interested in rural practice and primary care. Such programs serve both medical students and students of other health professions. Yet, little is known about student experiences in rural track programs. As such, this study aimed to generate discourse on student experiences in the rural training environment and gain insight into the impact of rural environments on student learning. METHODS: An exploratory qualitative analysis of medical and physician assistant student experiences in two rural medical education training programs was conducted using the photovoice methodology. Photovoice is a participatory research method combining photography with participant commentary and focus groups. RESULTS: Twenty-two third-year medical and six second-year physician assistant students participated in the study. Students noted that in their rural sites the learning environment extended beyond direct clinical teaching in four primary ways: (1) relationships with clinical faculty translated to a sense of meaningful participation in healthcare teams; (2) connections with community members outside of clinical settings led to increased awareness of healthcare concerns; (3) rural settings provided important space to reflect on their experiences; and (4) the importance of infrastructure was highlighted. Students also believed that diversity of occupation, education, attitude, and perception of medical care impact learning in rural environments. CONCLUSIONS: The photovoice participatory research methodology allowed for a deeper understanding of the aspects of the rural training experience that resonated most among students in real time, using visual representations of students' lived experiences as defined by the students.

RESUMO

The establishment of practice patterns concerning the diagnosis and management of hypovitaminosis D seems to be heterogeneous among primary care physicians. We conducted a qualitative study to explore the emerging practices among primary care providers regarding screening and treatment for hypovitaminosis D, as well as factors that influence practice patterns. Trained researchers facilitated focus groups among primary care providers. We followed a grounded theory approach to transcript coding and analysis using ATLAS.ti analysis software. Testing or screening for hypovitaminosis D and subsequent replacement or supplementation practices varied among participants. Emerging practice concerning vitamin D appears to be constructed and reinforced by patient demand; incidental reading; brief, purposeful research; conversations with colleagues; results of consultations by specialists; and more patient demand. A multifaceted approach to promoting guideline adherence will be required to influence this practice.

RESUMO

Oncolytic viruses are structurally and biologically diverse, spreading through tumors and killing them by various mechanisms and with different kinetics. Here, we created a hybrid vesicular stomatitis/measles virus (VSV/MV) that harnesses the safety of oncolytic MV, the speed of VSV, and the tumor killing mechanisms of both viruses. Oncolytic MV targets CD46 and kills by forcing infected cells to fuse with uninfected neighbors, but propagates slowly. VSV spreads rapidly, directly lysing tumor cells, but is neurotoxic and loses oncolytic potency when neuroattenuated by conventional approaches. The hybrid VSV/MV lacks neurotoxicity, replicates rapidly with VSV kinetics, and selectively targets CD46 on tumor cells. Its in vivo performance in a myeloma xenograft model was substantially superior to either MV or widely used recombinant oncolytic VSV-M51.

RESUMO

BACKGROUND: An increase in prior authorization (PA) requirements from health insurance companies is placing administrative and financial burdens on primary care offices across the United States. As time allocation for these cases continues to grow, physicians are concerned with additional workload and inefficiency in the workplace. The objective is to estimate the effects of practice characteristics on time spent per prior authorization request in primary care practices. METHODS: Secondary analysis was performed using data on nine primary care practices in Central New York. Practice characteristics and demographics were collected at the onset of the study. In addition, participants were instructed to complete an "event form" (EF) to document each prior authorization event during a 4-6 week period; prior authorizations included requests for medication as well as other health care services. Stepwise Ordinary Least Squares (OLS) Regression was used to model Time in Minutes of each event as an outcome of various factors. RESULTS: Prior authorization events (N = 435) took roughly 20 minutes to complete (beta = 20.017, p < .001); Medicaid requests took less time (beta = -6.085, p < .001), and Electronic Health Record (EHR) system use reduced prior authorization time by about 5 minutes (beta = -5.086, p = .002). CONCLUSIONS: While prior authorization events impose substantial costs to primary care offices, it appears that Medicaid requests take less time than private payer requests. Results from the study provide support that Electronic Health Record usage may also reduce time required to complete prior authorization requests.

RESUMO

BACKGROUND: A number of studies have indicated that students lose idealistic motivations over the course of medical education, with some identifying the initiation of this decline as occurring as early as the second year of the traditional US curricula. This study builds on prior work testing the hypothesis that a decline in medical student idealism is detectable in the first two years of medical school. METHODS: The original study sought to identify differences in survey responses between first-year (MS1) and second-year (MS2) medical students at the beginning and end of academic year 2010, on three proxies for idealism. The current study extends that work by administering the same survey items to the same student cohorts at the end of their third and fourth years (MS3 and MS4), respectively. Survey topics included questions on: (a) motivations for pursuing a medical career; (b) specialty choice; and (c) attitudes toward primary care. Principle component analysis was used to extract linear composite variables (LCVs) from responses to each group of questions. Linear regression was then used to test the effect of the six cohort/time-points on each composite variable, controlling for demographic characteristics. RESULTS: Idealism in medicine decreased (ß = -.113, p < .001) while emphasis on employment and job security increased (ß = .146, p < .001) as motivators of pursuing a career in medicine at each medical school stage and time period. Students were more likely to be motivated by student debt over interest in content in specialty choice (ß = .077, p = .004) across medical school stages. Negative attitudes towards primary care were most sensitive to MS group and time effects. Both negative/antagonistic views (ß = .142, p < .001) and negative/sympathetic views (ß = .091, p < .001) of primary care increased over each stage. CONCLUSIONS: Our results provide further evidence that declines in medical student idealism may occur as early as the second year of medical education. Additionally, as students make choices in their medical careers, such as specialty choice or consideration of primary care, the influences of job security, student debt and social status increasingly outweigh idealistic motivations.

RESUMO

BACKGROUND: Mesenchymal stem cells (MSC) can serve as carriers to deliver oncolytic measles virus (MV) to ovarian tumors. In preparation for a clinical trial to use MSC as MV carriers, we obtained cells from ovarian cancer patients and evaluated feasibility and safety of this approach. METHODS: MSC from adipose tissues of healthy donors (hMSC) and nine ovarian cancer patients (ovMSC) were characterized for susceptibility to virus infection and tumor homing abilities. RESULTS: Adipose tissue (range 0.16-3.96 grams) from newly diagnosed and recurrent ovarian cancer patients yielded about 7.41×106 cells at passage 1 (range 4-9 days). Phenotype and doubling times of MSC were similar between ovarian patients and healthy controls. The time to harvest of 3.0×108 cells (clinical dose) could be achieved by day 14 (range, 9-17 days). Two of nine samples tested had an abnormal karyotype represented by trisomy 20. Despite receiving up to 1.6×109 MSC/kg, no tumors were seen in SCID beige mice and MSC did not promote the growth of SKOV3 human ovarian cancer cells in mice. The ovMSC migrated towards primary ovarian cancer samples in chemotaxis assays and to ovarian tumors in athymic mice. Using non-invasive SPECT-CT imaging, we saw rapid co-localization, within 5-8 minutes of intraperitoneal administration of MV infected MSC to the ovarian tumors. Importantly, MSC can be pre-infected with MV, stored in liquid nitrogen and thawed on the day of infusion into mice without loss of activity. MV infected MSC, but not virus alone, significantly prolonged the survival of measles immune ovarian cancer bearing animals. CONCLUSIONS: These studies confirmed the feasibility of using patient derived MSC as carriers for oncolytic MV therapy. We propose an approach where MSC from ovarian cancer patients will be expanded, frozen and validated to ensure compliance with the release criteria. On the treatment day, the cells will be thawed, washed, mixed with virus, briefly centrifuged and incubated for 2 hours with virus prior to infusion of the virus/MSC cocktail into patients.

RESUMO

A major lack of expertise in vector biology, surveillance, and control for public health professionals has been acknowledged over the past several decades, especially in light of the introduction of West Nile and Zika viruses to the United States. To address this growing need, the Northeast Regional Center for Excellence in Vector-Borne Diseases (NEVBD) designed a unique educational program to cross-train students in the fundamentals of vector biology and public health. Here, we summarize the formation, evaluation, and outcomes of NEVBD's Master of Science in Entomology: Vector-Borne Disease Biology program and provide details on core competencies to enable adoption and adaptation of the program to other institutions and contexts. A discussion of major barriers to filling the nation's need for public health personnel with medical entomology training, such as financial barriers and recruitment of underrepresented students, is presented. We conclude with considerations for administering these training programs.

RESUMO

Introduction: Considering increasing rates of tick-borne diseases (TBDs) in the United States, we investigated the scope of continuing medical education (CME) available to physicians on these infections. Methods: We surveyed online medical board and society databases serving front-line primary and emergency/urgent care providers for the availability of TBD-specific CME between March 2022 and June 2022. We recorded and analyzed opportunity title, author, web address, publication year, learning objectives, CME credit values, and CME credit type. Results: We identified 70 opportunities across seven databases. Thirty-seven opportunities focused on Lyme disease; 17 covered nine non-Lyme TBDs, and 16 covered general topics on TBDs. Most activities were hosted through family medicine and internal medicine specialty databases. Conclusion: These findings suggest limited availability of continuing education for multiple life-threatening TBDs of increasing importance in the United States. Increasing the availability of CME materials covering the broad scope of TBDs in targeted specialty areas is essential for increased content exposure and a necessary step to ensure our clinical workforce is adequately prepared to address this growing public health threat.

RESUMO

In the United States, tick-borne diseases (TBDs) are a major public health concern and a source of significant morbidity. To reduce tick-borne disease incidence, understanding factors associated with increased risk in humans for tick bites is necessary. These risk factors can include TBD knowledge, attitudes about prevention and care, and associated practices of individuals and their communities, including paying for preventive services. Our study focused on Long Island, New York, a region with high endemicity of ticks and TBDs. The purpose of our study was to identify gaps in the knowledge, attitudes, and practices regarding TBDs in residents of this region to inform priorities for TBD interventions. To this end, we performed a knowledge, attitudes, and practices (KAP) survey and collected 803 responses from Long Island residents. Our survey results demonstrated that Long Island residents had a low to moderate level of knowledge regarding ticks and TBDs. Still, residents expressed concern regarding TBDs, with increased levels of concern associated with increased likelihood of paying for tick control and for practicing tick bite prevention strategies. Individuals with pets were more likely to practice these tick bite prevention strategies. Residents with more frequent exposure to ticks, with a history of TBD in their household, and with higher general concern over ticks were also more likely to pay for tick control services. These findings highlight gaps in resident knowledge, differences in attitudes towards tick preventative behavior, and potential factors affecting motivation towards implementing tick control measures, which can inform future public health messaging regarding tick bite prevention.

RESUMO

Zoos provide a unique opportunity to study mosquito feeding ecology as they represent areas where exotic animals, free-roaming native animals, humans, and mosquito habitats overlap. Therefore, these locations are a concern for arbovirus transmission to both valuable zoo animals and human visitors. We sampled mosquitoes in and around The Nashville Zoo at Grassmere in Tennessee, USA, over 4 months in 2020 using 4 mosquito trap methods and 12 sampling locations. Mosquitoes were identified to species, Culex mosquitoes were analyzed for arboviruses, and all engorged mosquitoes were preserved for host usage analysis. We captured over 9,000 mosquitoes representing 27 different species, including a new species record for Davidson County, TN (Culex nigripalpus Theobald). Minimum infection rates for West Nile virus (WNV) (Flaviviridae: Flavivirus), St. Louis encephalitis virus (Flaviviridae: Flavivirus), and Flanders virus (Hapavirus: Rhabdoviridae) were 0.79, 0, and 4.17, respectively. The collection of 100 engorged mosquitoes was dominated by Culex pipiens pipiens Linnaeus (38%), Culex erraticus Dyar and Knab (23%), and Culex pipiens pipiens-Culex pipiens quinquefasciatus hybrids (10%). Host DNA from 84 engorged mosquitoes was successfully matched to a variety of host species (n = 23), with just 8 species belonging to the zoo. Wild birds were the most frequently fed upon host, in particular northern cardinals (Cardinalis cardinalis L. Passeriformes: Cardinalidae), which are competent WNV reservoirs. Taken together, our results demonstrate the utility of zoos as sentinels for emerging pathogens, for studying wildlife and human risk of zoonotic diseases, and for assessing vector diversity.

RESUMO

Ticks and tick-borne diseases are an immense public health burden in New York State (NYS), United States. Tick species and associated pathogens are expanding into new areas, shifting threats to human, and animal health across the state. For example, the invasive tick, Haemaphysalis longicornis Neumann (Acari: Ixodidae), was first detected in the United States in 2017 and has since been identified in 17 states, including NYS. In addition, Amblyomma americanum (L.) (Acari: Ixodidae) is a native tick thought to be reestablishing historical populations in NYS. We implemented a community-based science project called the "NYS Tick Blitz" to determine the distribution of A. americanum and H. longicornis in NYS. Community volunteers were recruited, provided with education, training, and materials to conduct active tick sampling during a 2-wk period in June 2021. Fifty-nine volunteers sampled 164 sites across 15 counties, for a total of 179 separate collection events and 3,759 ticks collected. The most frequently collected species was H. longicornis, followed by Dermacentor variabilis Say (Acari: Ixodidae), Ixodes scapularis Say (Acari: Ixodidae), and A. americanum, respectively. Through the NYS Tick Blitz collections, H. longicornis was identified for the first time in Putnam County. We conducted pooled pathogen testing on a subset of specimens, with the highest rates of infection detected for pathogens transmitted by I. scapularis, including Borrelia burgdorferi, Anaplasma phagocytophilum, and Babesia microti. Most participants who completed a follow-up survey (n = 23, 71.9%) were promoters of the NYS Tick Blitz and 50% (n = 15) reported that they enjoyed participating in meaningful science.

RESUMO

Blacklegged ticks (Ixodes scapularis Say, Acari: Ixodidae) were collected from 432 locations across New York State (NYS) during the summer and autumn of 2015-2020 to determine the prevalence and geographic distribution of Borrelia miyamotoi (Spirochaetales: Spirochaetaceae) and coinfections with other tick-borne pathogens. A total of 48,386 I. scapularis were individually analyzed using a multiplex real-time polymerase chain reaction assay to simultaneously detect the presence of Bo. miyamotoi, Borrelia burgdorferi (Spirochaetales: Spirochaetaceae), Anaplasma phagocytophilum (Rickettsiales: Anaplasmataceae), and Babesia microti (Piroplasmida: Babesiidae). Overall prevalence of Bo. miyamotoi in host-seeking nymphs and adults varied geographically and temporally at the regional level. The rate of polymicrobial infection in Bo. miyamotoi-infected ticks varied by developmental stage, with certain co-infections occurring more frequently than expected by chance. Entomological risk of exposure to Bo. miyamotoi-infected nymphal and adult ticks (entomological risk index [ERI]) across NYS regions in relation to human cases of Bo. miyamotoi disease identified during the study period demonstrated spatial and temporal variation. The relationship between select environmental factors and Bo. miyamotoi ERI was explored using generalized linear mixed effects models, resulting in different factors significantly impacting ERI for nymphs and adult ticks. These results can inform estimates of Bo. miyamotoi disease risk and further our understanding of Bo. miyamotoi ecological dynamics in regions where this pathogen is known to occur.

RESUMO

Chagas disease (CD), caused by the parasite Trypanosoma cruzi, is a neglected parasitic infection in the United States (US). In the Southwestern US, National Park Service (NPS) employees are a unique population with potential exposure to CD. This population lives in close contact with several species of sylvatic triatomine bugs, the vectors of T. cruzi, that may enter residential buildings at night. Despite the higher potential risk of CD transmission for southwestern NPS employees, the socio-cultural factors that impact autochthonous CD transmission in the US remain unknown. To address this gap, we investigated how NPS employee knowledge and attitudes impact their triatomine preventive behaviors. We distributed a 42-item online questionnaire to NPS employees at four national parks in Arizona and Texas. We detected high self-reported bite exposure in NPS housing, despite moderate- to high-frequency of prevention behaviors. Specific behaviors, such as often or always repairing window screens, were associated with a decreased risk of putative triatomine bug exposure. Additionally, NPS employees had low knowledge of CD. For those with greater knowledge of CD, it was not associated with increased frequency of prevention behavior. We found that increased CD anxiety was associated with increased personal agency to reduce the risk of CD. These results demonstrate the influence of knowledge and attitudes regarding CD on triatomine prevention behavior within a potential high-risk population in the US, and the importance of utilizing strategies beyond provision of education to influence behaviors.

RESUMO

There has been limited research on patient-provider communication dynamics regarding Lyme disease (LD) diagnosis and treatment. Evidence suggests communication in the clinical encounter improves when both patient and healthcare provider (HCP) have concordant orientations (or beliefs) on discussed topics, resulting in higher patient satisfaction and care outcomes. The purpose of this scoping review was to characterize and summarize current research findings on patient and provider knowledge and experiences regarding LD - two factors that may influence the orientation of both patients and providers toward LD in the clinical setting. None of the articles included in the review specifically addressed patient-provider interaction and relationships as the main objective. However, the existing literature indicates notable HCP uncertainty regarding LD diagnosis, treatment, and applied practice patterns. Current research also describes limited knowledge of LD among patient populations and a high prevalence of negative perceptions of care received in mainstream healthcare settings among individuals with persistent symptoms. We identified a critical gap in research that seeks to understand the dynamic of patients and HCPs communicating on the topic of LD in the clinical setting. Future research may identify opportunities where the patient-provider communication dynamic can be improved.

RESUMO

Tickborne diseases are an increasing public health threat in the United States. Prevention and diagnosis of tickborne diseases are improved by access to current and accurate information on where medically important ticks and their associated human and veterinary pathogens are present, their local abundance or prevalence, and when ticks are actively seeking hosts. The true extent of tick and tickborne pathogen expansion is poorly defined, in part because of a lack of nationally standardized tick surveillance. We surveyed 140 vector-borne disease professionals working in state, county, and local public health and vector control agencies to assess their 1) tick surveillance program objectives, 2) pathogen testing methods, 3) tick control practices, 4) data communication strategies, and 5) barriers to program development and operation. Fewer than half of respondents reported that their jurisdiction was engaged in routine, active tick surveillance, but nearly two-thirds reported engaging in passive tick surveillance. Detection of tick presence was the most commonly stated current surveillance objective (76.2%). Most of the programs currently supporting tick pathogen testing were in the Northeast (70.8%), Upper and Central Midwest (64.3%), and the West (71.4%) regions. The most common pathogens screened for were Rickettsia spp. (Rickettsiales: Rickettsiaceae) and bacterial and viral agents transmitted by Ixodes (Acari: Ixodidae) ticks. Only 12% of respondents indicated their jurisdiction directly conducts or otherwise financially supports tick control. Responses indicated that their ability to expand the capacity of tick surveillance and control programs was impeded by inconsistent funding, limited infrastructure, guidance on best practices, and institutional capacity to perform these functions.

RESUMO

BACKGROUND: Vaccination coverage among children entering kindergarten in the United States is high, but interstate variations exist. The relationship between state immunization laws and vaccination coverage has not been fully assessed. We evaluated associations of state laws on both measles, mumps, and rubella (MMR) and diphtheria, tetanus, and pertussis (DTaP) vaccination coverage and exemptions to school immunization requirements. METHODS: We conducted a retrospective, longitudinal analysis of the effect of state immunization laws on vaccination coverage and exemptions among US kindergarteners from SY 2008 to SY 2014. The primary outcome measures were state-level kindergarten entry vaccination coverage rates for 2-dose MMR and 4-dose DTaP vaccines. Secondary outcome measures included rates of state-level exemptions (ie, medical, religious, philosophical) to school immunization requirements. RESULTS: We found that state policies that refer to Advisory Committee on Immunization Practices recommendations were associated with 3.5% and 2.8% increases in MMR and DTaP vaccination rates. Health Department-led parental education was associated with 5.1% and 4.5% increases in vaccination rates. Permission of religious and philosophical exemptions was associated with 2.3% and 1.9% decreases in MMR and DTaP coverage, respectively, and a 1.5% increase in both total exemptions and nonmedical exemptions, respectively. CONCLUSIONS: We found higher vaccination coverage and lower nonmedical exemption rates for MMR and DTaP vaccines in states adopting Advisory Committee on Immunization Practices guidelines for school entry. Adherence to these best practices was a successful strategy to increase vaccination coverage and reduce vaccination exemptions.
