Substance use patterns, sociodemographics, and health profiles of harm reduction service recipients in Burlington, Vermont.

BACKGROUND: Understanding current substance use practices is critical to reduce and prevent overdose deaths among individuals at increased risk including persons who use and inject drugs. Because individuals participating in harm reduction and syringe service programs are actively using drugs and vary in treatment participation, information on their current drug use and preferred drugs provides a unique window into the drug use ecology of communities that can inform future intervention services and treatment provision. METHODS: Between March and June 2023, 150 participants in a harm reduction program in Burlington, Vermont completed a survey examining sociodemographics; treatment and medication for opioid use disorder (MOUD) status; substance use; injection information; overdose information; and mental health, medical, and health information. Descriptive analyses assessed overall findings. Comparisons between primary drug subgroups (stimulants, opioids, stimulants-opioids) of past-three-month drug use and treatment participation were analyzed using chi-square and Fisher's exact test. RESULTS: Most participants reported being unhoused or unstable housing (80.7%) and unemployed (64.0%) or on disability (21.3%). The drug with the greatest proportion of participants reporting past three-month use was crack cocaine (83.3%). Fentanyl use was reported by 69.3% of participants and xylazine by 38.0% of participants. High rates of stimulant use were reported across all participants independent of whether stimulants were a participant's primary drug. Fentanyl, heroin, and xylazine use was less common in the stimulants subgroup compared to opioid-containing subgroups (p < .001). Current- and past-year MOUD treatment was reported by 58.0% and 77.3% of participants. Emergency rooms were the most common past-year medical treatment location (48.7%; M = 2.72 visits). CONCLUSIONS: Findings indicate high rates of polysubstance use and the underrecognized effects of stimulant use among people who use drugs-including its notable and increasing role in drug-overdose deaths. Crack cocaine was the most used stimulant, a geographical difference from much of the US where methamphetamine is most common. With the increasing prevalence of fentanyl-adulterated stimulants and differences in opioid use observed between subgroups, these findings highlight the importance and necessity of harm reduction interventions (e.g., drug checking services, fentanyl test strips) and effective treatment for individuals using stimulants alongside MOUD treatment.

Ecologically informed priors improve Bayesian model estimates of species richness and occupancy for undetected species.

Detection error can bias observations of ecological processes, especially when some species are never detected during sampling. In many communities, the probable identity of these missing species is known from previous research and natural history collections, but this information is rarely incorporated into subsequent models. Here, I present prior aggregation as a method for including information from external sources in Bayesian hierarchical detection models. Prior aggregation combines information from multiple prior distributions, in this case, an ecologically informative, species-level prior, and an uninformative community-level prior. This approach incorporates external information into the model without sacrificing the advantages of modeling species in the context of the community. Using simulated data supplied to a multispecies occupancy model, I demonstrated that prior aggregation improves estimates of (1) metacommunity richness and (2) environmental covariates were associated with species-specific occupancy probabilities. When applied to a dataset of small mammals in Vermont, prior aggregation allowed the model to estimate occupancy correlates of the Eastern cottontail Sylvilagus floridanus, a species observed at several sites in the region but never captured. Prior aggregation can be used to improve the analysis of several important metrics in population and community ecology, including abundance, survivorship, and diversity.

Transfer Patterns Among Infants Born at 28 to 34 Weeks' Gestation.

BACKGROUND: Although postnatal transfer patterns among high-risk (eg, extremely preterm or surgical) infants have been described, transfer patterns among lower-risk populations are unknown. The objective was to examine transfer frequency, indication, timing, and trajectory among very and moderate preterm infants. METHODS: Observational study of the US Vermont Oxford Network all NICU admissions database from 2016 to 2021 of inborn infants 280/7 to 346/7 weeks. Infants' first transfer was assessed by gestational age, age at transfer, reason for transfer, and transfer trajectory. RESULTS: Across 467 hospitals, 294 229 infants were eligible, of whom 12 552 (4.3%) had an initial disposition of transfer. The proportion of infants transferred decreased with increasing gestational age (9.6% [n = 1415] at 28 weeks vs 2.4% [n = 2646] at 34 weeks) as did the median age at time of transfer (47 days [interquartile range 30-73] at 28 weeks vs 8 days [interquartile range 3-16] at 34 weeks). The median post menstrual age at transfer was 34 or 35 weeks across all gestational ages. The most common reason for transfer was growth or discharge planning (45.0%) followed by medical and diagnostic services (30.2%), though this varied by gestation. In this cohort, 42.7% of transfers were to a higher-level unit, 10.2% to a same-level unit, and 46.7% to a lower-level unit, with indication reflecting access to specific services. CONCLUSIONS: Over 4% of very and moderate preterm infants are transferred. In this population, the median age of transfer is later and does not reflect immediate care needs after birth, but rather the provision of risk-appropriate care.

Using Insurance Claims Data to Estimate Blastomycosis Incidence, Vermont, USA, 2011-2020.

The epidemiology of blastomycosis in Vermont, USA, is poorly understood. Using insurance claims data, we estimated the mean annual blastomycosis incidence was 1.8 patients/100,000 persons during 2011-2020. Incidence and disease severity were highest in north-central counties. Our findings highlight a need for improved clinical awareness and expanded surveillance.

Oral Rabies Vaccination of Raccoons (Procyon lotor) across a Development Intensity Gradient in Burlington, Vermont, USA, 2015-2017.

Management of the raccoon rabies virus variant in North America is conducted primarily using oral rabies vaccination (ORV). When a sufficient proportion of the population is vaccinated (∼60%), rabies transmission can be eliminated. To date, ORV programs have successfully controlled and eliminated raccoon rabies in rural areas, but there has been less success in urban areas. We studied the proportions of rabies virus neutralizing antibodies (RVNA) in a raccoon (Procyon lotor) population during a 3-yr ORV trial in developed areas of Burlington, Vermont, US. We used a modified N-mixture model to estimate raccoon abundance, RVNA seroprevalence, and capture rates jointly to examine factors that relate to ORV success to better inform management. We found that raccoon abundance was lower in less-developed areas compared to urban centers. Raccoon RVNA seroprevalence decreased as population abundance increased; it increased as the average age of the population increased. Nontarget opossum (Didelphis virginiana) captures correlated with a decrease in raccoon RVNA seroprevalence in low-development areas, suggesting that they may be competing for baits. The target bait density across the entire study area was 150 baits/km2, but a hand baiting strategy was heavily concentrated on roads, resulting in uneven bait densities within sampling sites (0-484 baits/km2). Uneven bait distribution across the study area may explain low RVNA seroprevalence in some locations. Our results suggest that increases in bait density across the study area may improve RVNA seroprevalence and support annual ORV to account for raccoon population turnover.

An ethnographic study of a community dentistry network serving Latine migrant farmworkers in Vermont: Barriers and access to care during the COVID-19 pandemic and beyond.

BACKGROUND AND OBJECTIVES: Primary dental healthcare services are not accessible for a majority of Latino/a/e migrant farmworkers in the United States. Unmet dental health needs are well documented in larger states like California, Florida and New York, but the dental healthcare picture in smaller states is not well understood. The goal of this qualitative ethnographic study was to understand the delivery model of a free dentistry network serving Latine farmworkers in rural Vermont and specific barriers experienced at the network during the COVID-19 pandemic. METHODS: Semi-structured ethnographic interviews were carried out with clinicians and transcripts were analysed using the constant comparison method to identify salient concerns and recommendations about barriers and delivery of care. RESULTS: Clinicians highlighted structural issues including farmworkers' lack of time off work and absence of transportation to attend appointments, concerns about COVID-19 safety, concerns about immigration surveillance and language barriers. Providers outlined steps for improved service delivery including mobile care at local farms, enhanced intercultural training for providers, recognizing dentistry as essential healthcare at the state level and the leverage of existing appointments for preventive health. Drawing on anthropological frameworks of place-based care and deservingness of healthcare, our ethnographic findings emphasize the role of community dentistry in bridging gaps in migrant healthcare during and beyond the COVID-19 pandemic.

Perceptions and Attitudes Toward Genetic Counselors and Genetic Testing Among Certified Professional Midwives in Vermont: A Modified Grounded Theory Study.

Increasingly, pregnant people in the United States are choosing to give at birth at home, and certified professional midwives (CPMs) often attend these births. Care by midwives, including home birth midwives, has the potential to decrease unnecessary medical interventions and their associated health care costs, as well as to improve maternal satisfaction with care. However, lack of integration into the health care system affects the ability of CPMs to access standard medications and testing for their clients, including prenatal screening. Genetics and genomics are now a routine part of prenatal screening, and genetic testing can contribute to identifying candidates for planned home birth. However, research on genetics and midwifery care has not, to date, included the subset of midwives who attend the majority of planned home births, CPMs. The purpose of this study was to examine CPMs' access to, and perspectives on, one aspect of prenatal care, genetic counselors and genetic counseling services. Using semi-structured interviews and a modified grounded theory approach to narrative analysis, we identified three key themes: (1) systems-level issues with accessing information about genetic counseling and genetic testing; (2) practice-level patterns in information delivery and self-awareness about knowledge limitations; and (3) client-level concerns about the value of genetic testing relative to difficulties with access and stress caused by the information. The results of this study can be used to develop decision aids that include information about genetic testing and genetic counseling access for pregnant people intending home births in the United States.

Beliefs and Attitudes about Vermont's Buprenorphine Decriminalization Law among Clinicians Who Prescribe Buprenorphine.

BACKGROUND: On June 1, 2021, Vermont repealed all criminal penalties for possessing 224 milligrams or less of buprenorphine. We examined the potential impact of decriminalization with a survey of Vermont clinicians who prescribed buprenorphine within the past year. METHODS: All 638 Vermont clinicians with a waiver to prescribe buprenorphine were emailed the survey by Vermont Department of Health; 117 responded. We estimated the prevalence of the following four outcomes, for all responding clinicians and stratified by clinician demographics and practice characteristics: awareness of decriminalization, beliefs about the effects of decriminalization, support for decriminalization, and changes in practice resulting from decriminalization. RESULTS: 72 (62%) prescribers correctly stated that Vermont does not have criminal penalties for buprenorphine possession. 107 (91%) support decriminalization. 56 (48%) believe that, because buprenorphine is decriminalized, their patients are more likely to give, sell, or trade the buprenorphine that is prescribed to them to someone else. However, only 5 providers (4%) said they now prescribe to fewer patients. CONCLUSION: The great majority of Vermont clinicians who prescribe buprenorphine support its decriminalization and have not changed their prescribing practices because of decriminalization.

In 2021, Vermont repealed criminal penalties for buprenorphine possession.We surveyed Vermont (n = 117) buprenorphine prescribers about decriminalization.91% of providers support decriminalization.48% of providers believe decriminalization will increase diversion of medications.Only 4% of providers prescribe to fewer patients because of decriminalization.

U.S. consumer support for genetically modified foods: Time trends and assessments of four GM attributes.

There is a large literature about consumer acceptance of GM foods dating back almost three decades, but there are fewer studies that investigate how support for specific GM attributes contribute to general support for novel plant technologies. In addition, there is little information on how support has changed over time. Using survey data from 2018 to 2023 in a U.S. State (Vermont) (n = 3101), we analyze changes in support for a variety of GM attributes over time. There are three major findings. First, there is movement toward neutrality in support for various GM attributes, but opposition continues. Second, there is variability in support for different GM attributes. People are most supportive (least opposed) to GM attributes that improve flora (plant health or drought tolerance), and most opposed (least supportive) of attributes that impact fauna (specifically fish). Third, multivariate regression reveals that assessments of individual GM attributes contribute to levels of overall support of the use of GM technologies in agricultural production.

Statewide Trends in Buprenorphine Prescribing in Rural and Nonrural Vermont: Analysis of Population-based Patient Pharmacy Claims.

IMPORTANCE: Opioid-related mortality rates have risen dramatically over the past decade, and office-based opioid treatment using buprenorphine offers hope for combatting this trend. Vermont's policymakers, health care systems, and treatment providers have worked to expand access to treatment throughout the rural state. OBJECTIVE: The objective of the current study was to characterize the trends in the number of buprenorphine prescribers and the number of patients per prescriber in Vermont over the past decade (2010-2020). METHODS: We used Vermont's all-payer claims database to identify patients with buprenorphine claims between 2010 and 2020 and their prescribers. We conducted analyses of trends in the number of prescribers treating different numbers of patients, the number of patients treated by prescribers in those categories, and the number of rural (vs nonrural) patients filling buprenorphine prescriptions. We used Z tests to determine if there were statistical differences between trends. RESULTS: The number of buprenorphine prescribers treating 10+ patients grew more rapidly than other prescriber groups ( P < 0.001). Nearly half of Vermont patients in 2020 were treated by 33 high-volume prescribers who treated 100 or more patients with buprenorphine. The number of patients filling buprenorphine prescriptions in Vermont increased by 98% between 2010 and 2020, with greater increases seen among rural than nonrural residents (107% vs 72%; P = 0.008). CONCLUSIONS AND RELEVANCE: Since 2010, Vermont has increased utilization of its office-based opioid treatment capacity, particularly in rural counties.

Determining Unmet Needs Among Workers' Compensation Stakeholders to Prevent Work Disability in the State of Vermont.

PURPOSE: Vermont has high rates of young people receiving federal disability benefits leading to substantial gaps in the workforce. The purpose of this project was to determine the unmet needs of interested parties in the workers' compensation (WC) process. METHODS: A type of focus group, experience groups, was used to elicit key parties' experiences in the WC system. Facilitators used open-ended prompts to encourage discussion among participants about their experience with the WC system. Data were analyzed using thematic coding procedures to identify common motifs. RESULTS: Common themes emerged including challenges in navigating the WC system, lack of communication among stakeholders, and providing and receiving appropriate health care to facilitate RTW. CONCLUSIONS: Understanding unmet needs of interested parties in the WC process allows for the creation of targeted, high-value, early intervention strategies to reduce long-term work disability.

Polyurethane Foam Emission Samplers to Identify Sources of Airborne Polychlorinated Biphenyls from Glass-Block Windows and Other Room Surfaces in a Vermont School.

We hypothesized that emissions of polychlorinated biphenyls (PCBs) from Aroclor mixtures present in building materials explain their concentrations in school air. Here, we report a study of airborne concentrations and gas-phase emissions in three elementary school rooms constructed in 1958. We collected airborne PCBs using polyurethane foam passive air samplers (PUF-PAS, n = 6) and PCB emissions from building materials using polyurethane foam passive emission samplers (PUF-PES, n = 17) placed over flat surfaces in school rooms, including vinyl tile floors, carpets, painted bricks, painted drywall, and glass-block windows. We analyzed all 209 congeners represented in 173 chromatographic separations and found that the congener distribution in PUF-PES strongly resembled the predicted diffusive release of gas-phase PCBs from a solid material containing Aroclor 1254. Concentrations of airborne total PCBs ranged from 38 to 180 ng m-3, a range confirmed by an independent laboratory in the same school. These levels exceed action levels for all aged children set by the State of Vermont and exceed guidance levels set by the U.S. EPA for children under age 3. Emissions of PCBs from the glass-block windows (30,000 ng m-2 d-1) greatly exceeded those of all other surfaces, which ranged from 35 to 2700 ng m-2 d-1. This study illustrates the benefit of the direct measurement of PCB emissions to identify the most important building remediation needed to reduce airborne PCB concentrations in schools.

Surveillance of Vermont wildlife in 2021-2022 reveals no detected SARS-CoV-2 viral RNA.

Previous studies have documented natural infections of SARS-CoV-2 in various domestic and wild animals. More recently, studies have been published noting the susceptibility of members of the Cervidae family, and infections in both wild and captive cervid populations. In this study, we investigated the presence of SARS-CoV-2 in mammalian wildlife within the state of Vermont. 739 nasal or throat samples were collected from wildlife throughout the state during the 2021 and 2022 harvest season. Data was collected from red and gray foxes (Vulpes vulples and Urocyon cineroargentus, respectively), fishers (Martes pennati), river otters (Lutra canadensis), coyotes (Canis lantrans), bobcats (Lynx rufus rufus), black bears (Ursus americanus), and white-tailed deer (Odocoileus virginianus). Samples were tested for the presence of SARS-CoV-2 via quantitative RT-qPCR using the CDC N1/N2 primer set and/or the WHO-E gene primer set. Surprisingly, we initially detected a number of N1 and/or N2 positive samples with high cycle threshold values, though after conducting environmental swabbing of the laboratory and verifying with a second independent primer set (WHO-E) and PCR without reverse transcriptase, we showed that these were false positives due to plasmid contamination from a construct expressing the N gene in the general laboratory environment. Our final results indicate that no sampled wildlife were positive for SARS-CoV-2 RNA, and highlight the importance of physically separate locations for the processing of samples for surveillance and experiments that require the use of plasmid DNA containing the target RNA sequence. These negative findings are surprising, given that most published North America studies have found SARS-CoV-2 within their deer populations. The absence of SARS-CoV-2 RNA in populations sampled here may provide insights in to the various environmental and anthropogenic factors that reduce spillover and spread in North American's wildlife populations.

A Survey of Cancer Risk Behaviors, Beliefs, and Social Drivers of Health in New Hampshire and Vermont.

Compared with urban areas, rural areas have higher cancer mortality and have experienced substantially smaller declines in cancer incidence in recent years. In a New Hampshire (NH) and Vermont (VT) survey, we explored the roles of rurality and educational attainment on cancer risk behaviors, beliefs, and other social drivers of health. In February-March 2022, two survey panels in NH and VT were sent an online questionnaire. Responses were analyzed by rurality and educational attainment. Respondents (N = 1,717, 22%) mostly lived in rural areas (55%); 45% of rural and 25% of urban residents had high school education or less and this difference was statistically significant. After adjustment for rurality, lower educational attainment was associated with smoking, difficulty paying for basic necessities, greater financial difficulty during the COVID-19 pandemic, struggling to pay for gas (P < 0.01), fatalistic attitudes toward cancer prevention, and susceptibility to information overload about cancer prevention. Among the 33% of respondents who delayed getting medical care in the past year, this was more often due to lack of transportation in those with lower educational attainment (21% vs. 3%, P = 0.02 adjusted for rurality) and more often due to concerns about catching COVID-19 among urban than rural residents (52% vs. 21%; P < 0.001 adjusted for education). In conclusion, in NH/VT, smoking, financial hardship, and beliefs about cancer prevention are independently associated with lower educational attainment but not rural residence. These findings have implications for the design of interventions to address cancer risk in rural areas. Significance: In NH and VT, the finding that some associations between cancer risk factors and rural residence are more closely tied to educational attainment than rurality suggest that the design of interventions to address cancer risk should take educational attainment into account.

Attitudes and beliefs about Vermont's 2021 buprenorphine decriminalization law among residents who use illicit opioids.

BACKGROUND: In July 2021, Vermont removed all criminal penalties for possessing 224mg or less of buprenorphine. METHODS: Vermont residents (N=474) who used illicit opioid drugs or received treatment for opioid use disorder in the past 90 days were recruited for a mixed-methods survey on the health and criminal legal effects of decriminalization. Topics assessed included: motivations for using non-prescribed buprenorphine, awareness of and support for decriminalization, and criminal legal system experiences involving buprenorphine. We examined the frequencies of quantitative measures and qualitatively summarized themes from free-response questions. RESULTS: Three-quarters of respondents (76%) reported lifetime use of non-prescribed buprenorphine. 80% supported decriminalization, but only 28% were aware buprenorphine was decriminalized in Vermont. Respondents described using non-prescribed buprenorphine to alleviate withdrawal symptoms and avoid use of other illicit drugs. 18% had been arrested while in buprenorphine, with non-White respondents significantly more likely to report such arrests (15% v 33%, p<0.001). CONCLUSION: Decriminalization of buprenorphine may reduce unnecessary criminal legal system involvement, but its health impact was limited by low awareness at the time of our study.

Pharmacy benefit considerations for continuous glucose monitoring acquisition: Vermont Medicaid experience.

Many individuals with diabetes are not achieving their glycemic goals. Use of continuous glucose monitoring (CGM) improves diabetes management. Access to CGM is often hindered when individuals must acquire their supplies through the traditional durable medical device channel. Vermont Medicaid transitioned CGM coverage from a medical/durable medical equipment benefit to a pharmacy benefit. This improved access and lessened the burden on prescribing health care providers. We describe the process the Vermont Medicaid program implemented to make this transition. DISCLOSURES: Funding for editorial assistance in the development of this manuscript was provided by Abbott Diabetes Care. The funder had no input in the manuscript content. The authors received no compensation.

Lessons learned from linking two complementary databases: the Society of Thoracic Surgeons Congenital Heart Surgery Database and The Vermont Oxford Network Expanded Database.

The Society of Thoracic Surgeons Congenital Heart Surgery Database and the Vermont Oxford Network Expanded Database are both large, international, well-established quality and outcomes databases with high penetration in their respective fields of congenital heart surgery and neonatology. Previous studies have shown the value of combining large databases for research purposes. Our aim was to examine the feasibility and value of combining these databases on a local level.We included patients from both databases, cared for at our centre and born from 2015-2020, who had cardiac surgery as neonates or during the birth hospitalisation. We examined the number of patients from each database and overlap between the two. We compared cardiac diagnoses, surgeries performed, pre-operative factors, mortality, and length of stay between databases.Of the 255 patients meeting criteria, 209 (81.9%) had records in both databases. The most common diagnoses in both were hypoplastic left heart syndrome, coarctation, and transposition of the great arteries. Surgical data were incompletely recorded in Vermont Oxford. Gestational age, birth weight, multiple gestation, mortality, and length of stay did not differ significantly between the databases, while the percentage of patients with an extracardiac malformation or genetic syndrome recorded was higher in the Society for Thoracic Surgeons group.Larger-scale matching and comparison studies using these databases are feasible and desirable; for some variables, a record with data from both databases may be more complete. Specific attention should be given to inclusion criteria, reconciling different schema of diagnoses, and formulating questions relying on each database's relative strengths.

The Vermont Family Based Approach in Primary Care Pediatrics: Effects on Children's and Parents' Emotional and Behavioral Problems and Parents' Health-Related Quality of Life.

This randomized controlled trial tested the Vermont Family Based Approach (VFBA) in primary care pediatrics. The VFBA is a model of healthcare delivery that shifts the focus from the individual to the family, emphasizes emotional and behavioral health, and uses evidence-based health promotion/prevention along with the treatment of emotional and behavioral problems. Participants were 81 families of 3-15-year-olds. For children, the VFBA was associated with greater reductions than the Control condition on the Child Behavior Checklist Emotionally Reactive, Withdrawn, Sleep Problems, Aggressive Behavior and Total Problems scales. For parents, the VFBA was associated with greater reductions than the Control condition on the Adult Self-Report Anxious/Depressed, Rule-Breaking Behavior, Internalizing Problems and Total Problems scales. The VFBA was also associated with greater improvement than the Control condition in the parents' health-related quality of life, as indicated by all scales of the Medical Outcomes Study Health Survey.
