Engaging Antiracist And Decolonial Praxis To Advance Equity In Oregon Public Health Surveillance Practices.

Public health surveillance and data systems in the US remain an unnamed facet of structural racism. What gets measured, which data get collected and analyzed, and how and by whom are not matters of happenstance. Rather, surveillance and data systems are productions and reproductions of political priority, epistemic privilege, and racialized state power. This has consequences for how communities of color are represented or misrepresented, viewed, and valued and for what is prioritized and viewed as legitimate cause for action. Surveillance and data systems accordingly must be understood as both an instrument of structural racism and an opportunity to dismantle it. Here, we outline a critique of standard surveillance systems and practice, drawing from the social epidemiology, critical theory, and decolonial theory literatures to illuminate matters of power germane to epistemic and procedural justice in the surveillance of communities of color. We then summarize how community partners, academics, and state health department data scientists collaborated to reimagine survey practices in Oregon, engaging public health critical race praxis and decolonial theory to reorient toward antiracist surveillance systems. We close with a brief discussion of implications for practice and areas for continued consideration and reflection.

Oregon's Approach To Demonstrating The Value Of A Modern Public Health System Through Accountability Metrics.

Oregon's public health system uses accountability metrics to improve health, eliminate inequities, and practice stewardship. First enacted into law during the 2015 legislative session, with additions and clarifications made in the 2017 session, these metrics promote collective action across sectors, bring attention to the root causes of health inequities, and hold public health authorities accountable for performance improvement as they carry out core public health functions. This article describes the development of Oregon's accountability metrics and implications for future practice. In 2023, Oregon's public health leaders adopted a new set of health outcome indicators and process measures for communicable disease control and environmental health, with performance tied to financial incentives. Oregon's process is a model for other states developing an accountability framework in their pursuit of public health transformation. Oregon's work contributes to legislative and other policy decisions for measuring the success of approaches to eliminating health inequities and for applying performance-based incentives within the public health system.

Evaluation of a Suspected Overdose Form for Timely Surveillance of Fatal Drug Overdoses, Multnomah County, OR, 2020-2021.

OBJECTIVES: There is a significant delay in finalization of drug overdose deaths, and a need to more quickly identify suspected overdoses to improve public health response. The objective of our study was to describe creation of a suspect overdose form and evaluate its use. DESIGN: Evaluation of a suspected overdose form used to record information related to death investigation with matching to state vital records. We calculated the toxicology turnaround time for matched records, and also calculated sensitivity, specificity, positive predictive value, and negative predictive value of the form compared to vital records as the gold standard. SETTING: Multnomah County, Oregon, deaths investigated by the County Medical Examiner between January 2020 and December 2021. MAIN OUTCOME MEASURE: Sensitivity of the suspected overdose form. RESULTS: We analyzed 2818 matched death records in total during the study period. The average turnaround time for the 1673 records with toxicology results was 101 days. In 2020, sensitivity of the form was 74%, but this increased to nearly 95% in 2021. CONCLUSIONS: Multnomah County's suspected evaluation form provides a timelier indicator of deaths suspected to be from drug overdose, has good sensitivity to detect true overdoses, and can help guide more rapid public health and public safety response activities.

Forest carbon sequestration on the west coast, USA: Role of species, productivity, and stockability.

Forest ecosystems store large amounts of carbon and can be important sources, or sinks, of the atmospheric carbon dioxide that is contributing to global warming. Understanding the carbon storage potential of different forests and their response to management and disturbance events are fundamental to developing policies and scenarios to partially offset greenhouse gas emissions. Projections of live tree carbon accumulation are handled differently in different models, with inconsistent results. We developed growth-and-yield style models to predict stand-level live tree carbon density as a function of stand age in all vegetation types of the coastal Pacific region, US (California, Oregon, and Washington), from 7,523 national forest inventory plots. We incorporated site productivity and stockability within the Chapman-Richards equation and tested whether intensively managed private forests behaved differently from less managed public forests. We found that the best models incorporated stockability in the equation term controlling stand carrying capacity, and site productivity in the equation terms controlling the growth rate and shape of the curve. RMSEs ranged from 10 to 137 Mg C/ha for different vegetation types. There was not a significant effect of ownership over the standard industrial rotation length (~50 yrs) for the productive Douglas-fir/western hemlock zone, indicating that differences in stockability and productivity captured much of the variation attributed to management intensity. Our models suggest that doubling the rotation length on these intensively managed lands from 35 to 70 years would result in 2.35 times more live tree carbon stored on the landscape. These findings are at odds with some studies that have projected higher carbon densities with stand age for the same vegetation types, and have not found an increase in yields (on an annual basis) with longer rotations. We suspect that differences are primarily due to the application of yield curves developed from fully-stocked, undisturbed, single-species, "normal" stands without accounting for the substantial proportion of forests that don't meet those assumptions. The carbon accumulation curves developed here can be applied directly in growth-and-yield style projection models, and used to validate the predictions of ecophysiological, cohort, or single-tree style models being used to project carbon futures for forests in the region. Our approach may prove useful for developing robust models in other forest types.

Resistance of rocky intertidal communities to oceanic climate fluctuations.

A powerful way to predict how ecological communities will respond to future climate change is to test how they have responded to the climate of the past. We used climate oscillations including the Pacific Decadal Oscillation (PDO), North Pacific Gyre Oscillation, and El Niño Southern Oscillation (ENSO) and variation in upwelling, air temperature, and sea temperatures to test the sensitivity of nearshore rocky intertidal communities to climate variability. Prior research shows that multiple ecological processes of key taxa (growth, recruitment, and physiology) were sensitive to environmental variation during this time frame. We also investigated the effect of the concurrent sea star wasting disease outbreak in 2013-2014. We surveyed nearly 150 taxa from 11 rocky intertidal sites in Oregon and northern California annually for up to 14-years (2006-2020) to test if community structure (i.e., the abundance of functional groups) and diversity were sensitive to past environmental variation. We found little to no evidence that these communities were sensitive to annual variation in any of the environmental measures, and that each metric was associated with < 8.6% of yearly variation in community structure. Only the years elapsed since the outbreak of sea star wasting disease had a substantial effect on community structure, but in the mid-zone only where spatially dominant mussels are a main prey of the keystone predator sea star, Pisaster ochraceus. We conclude that the established sensitivity of multiple ecological processes to annual fluctuations in climate has not yet scaled up to influence community structure. Hence, the rocky intertidal system along this coastline appears resistant to the range of oceanic climate fluctuations that occurred during the study. However, given ongoing intensification of climate change and increasing frequencies of extreme events, future responses to climate change seem likely.

The Ability of Primary Care Practices to Measure and Report on Care Quality.

BACKGROUND: Creating useful clinical quality measure (CQM) reports in a busy primary care practice is known to depend on the capability of the electronic health record (EHR). Two other domains may also contribute: supportive leadership to prioritize the work and commit the necessary resources, and individuals with the necessary health information technology (IT) skills to do so. Here we describe the results of an assessment of the above 3 domains and their associations with successful CQM reporting during an initiative to improve smaller primary care practices' cardiovascular disease CQMs. METHODS: The study took place within an AHRQ EvidenceNOW initiative of external support for smaller practices across Washington, Oregon and Idaho. Practice facilitators who provided this support completed an assessment of the 3 domains previously described for each of their assigned practices. Practices submitted 3 CQMs to the study team: appropriate aspirin prescribing, use of statins when indicated, blood pressure control, and tobacco screening/cessation. RESULTS: Practices with advanced EHR reporting capability were more likely to report 2 or more CQMs. Only one-third of practices were "advanced" in this domain, and this domain had the highest proportion of practices (39.1%) assessed as "basic." The presence of advanced leadership or advanced skills did not appreciably increase the proportion of practices that reported 2 or more CQMs. CONCLUSIONS: Our findings support previous reports of limited EHR reporting capabilities within smaller practices but extend these findings by demonstrating that practices with advanced capabilities in this domain are more likely to produce CQM reports.

A machine learning approach to detect potentially harmful and protective suicide-related content in broadcast media.

Suicide-related media content has preventive or harmful effects depending on the specific content. Proactive media screening for suicide prevention is hampered by the scarcity of machine learning approaches to detect specific characteristics in news reports. This study applied machine learning to label large quantities of broadcast (TV and radio) media data according to media recommendations reporting suicide. We manually labeled 2519 English transcripts from 44 broadcast sources in Oregon and Washington, USA, published between April 2019 and March 2020. We conducted a content analysis of media reports regarding content characteristics. We trained a benchmark of machine learning models including a majority classifier, approaches based on word frequency (TF-IDF with a linear SVM) and a deep learning model (BERT). We applied these models to a selection of more simple (e.g., focus on a suicide death), and subsequently to putatively more complex tasks (e.g., determining the main focus of a text from 14 categories). Tf-idf with SVM and BERT were clearly better than the naive majority classifier for all characteristics. In a test dataset not used during model training, F1-scores (i.e., the harmonic mean of precision and recall) ranged from 0.90 for celebrity suicide down to 0.58 for the identification of the main focus of the media item. Model performance depended strongly on the number of training samples available, and much less on assumed difficulty of the classification task. This study demonstrates that machine learning models can achieve very satisfactory results for classifying suicide-related broadcast media content, including multi-class characteristics, as long as enough training samples are available. The developed models enable future large-scale screening and investigations of broadcast media.

A stepwise approach to integrating the new essentials into a master's entry nursing curriculum.

The American Association of Colleges of Nursing (AACN) released updated nursing curriculum Essentials in 2021. The new Essentials document reflects an innovative and unique approach to nursing education and provides a framework for competency-based education and assessment to prepare students to work in a profession that is ever-changing. The first in the state of Oregon, a Masters Entry into Professional Nursing program was launched with a curriculum based on the new Essentials with the goal to remain true to the program's current concept-based approach while incorporating elements of a competency-based curriculum. As with all new programs, curricular design is paramount and requires careful planning to ensure the curriculum aligns with education trends, meets the needs of diverse learners, adheres to regulatory requirements and standards, and has strong faculty buy-in. Curriculum development done in a systematic fashion with faculty input is imperative. All current faculty were invited by the school of nursing (SON) leadership to participate in the curriculum development process. Regularly scheduled meetings were held, and all interested faculty participants were able to provide input. This process also included the SON Curriculum Committee and SON Faculty Council, to ensure all faculty were included in the process and appraised of the curriculum development. The faculty members who participated in the systematic development process then served as advocates for the new curriculum and helped create a smooth transition when the new MEPN program was introduced.

Community Partner Perceptions of Equitable Implementation Practices for a Promotores de Salud Intervention: A Qualitative Assessment.

We conducted focus groups with staff from 5 community-based organizations (21 participants; 86% female, 52% Hispanic/Latino/a/x and 24% Mexican/Mexican American) between August and October 2021. Results highlighted community partner perceptions of practices congruent (e.g., communication that built trust and dismantled power dynamics, a shared mission) and incongruent (e.g., intervention-community misalignment, research driven decision-making) with equitable implementation in the development, implementation, and evaluation of a promotores de salud intervention to increase COVID-19 testing and preventive behaviors among Latinx communities in Oregon.

Assessment of Risk for Sudden Cardiac Death Among Adolescents and Young Adults After Receipt of COVID-19 Vaccine - Oregon, June 2021-December 2022.

COVID-19 vaccination has been associated with myocarditis in adolescents and young adults, and concerns have been raised about possible vaccine-related cardiac fatalities in this age group. In April 2021, cases of myocarditis after COVID-19 vaccination, particularly among young male vaccine recipients, were reported to the Vaccine Adverse Event Reporting System. To assess this possibility, investigators searched death certificates for Oregon residents aged 16-30 years who died during June 2021-December 2022 for cardiac or undetermined causes of death. For identified decedents, records in Oregon's immunization information system were reviewed for documentation of mRNA COVID-19 vaccination received ≤100 days before death. Among 1,292 identified deaths, COVID-19 was cited as the cause for 30. For 101 others, a cardiac cause of death could not be excluded; among these decedents, immunization information system records were available for 88, three of whom had received an mRNA COVID-19 vaccination within 100 days of death. Of 40 deaths that occurred among persons who had received an mRNA COVID-19 vaccine dose, three occurred ≤100 days after vaccination. Two of these deaths were attributed to chronic underlying conditions; the cause was undetermined for one. No death certificate attributed death to vaccination. These data do not support an association between receipt of mRNA COVID-19 vaccine and sudden cardiac death among previously healthy young persons. COVID-19 vaccination is recommended for all persons aged ≥6 months to prevent COVID-19 and complications, including death.

Cross-scale analysis reveals interacting predictors of annual and perennial cover in Northern Great Basin rangelands.

Exotic annual grass invasion is a widespread threat to the integrity of sagebrush ecosystems in Western North America. Although many predictors of annual grass prevalence and native perennial vegetation have been identified, there remains substantial uncertainty about how regional-scale and local-scale predictors interact to determine vegetation heterogeneity, and how associations between vegetation and cattle grazing vary with environmental context. Here, we conducted a regionally extensive, one-season field survey across burned and unburned, grazed, public lands in Oregon and Idaho, with plots stratified by aspect and distance to water within pastures to capture variation in environmental context and grazing intensity. We analyzed regional-scale and local-scale patterns of annual grass, perennial grass, and shrub cover, and examined to what extent plot-level variation was contingent on pasture-level predictions of site favorability. Annual grasses were widespread at burned and unburned sites alike, contrary to assumptions of annual grasses depending on fire, and more common at lower elevations and higher temperatures regionally, as well as on warmer slopes locally. Pasture-level grazing pressure interacted with temperature such that annual grass cover was associated positively with grazing pressure at higher temperatures but associated negatively with grazing pressure at lower temperatures. This suggests that pasture-level temperature and grazing relationships with annual grass abundance are complex and context dependent, although the causality of this relationship deserves further examination. At the plot-level within pastures, annual grass cover did not vary with grazing metrics, but perennial cover did; perennial grasses, for example, had lower cover closer to water sources, but higher cover at higher dung counts within a pasture, suggesting contrasting interpretations of these two grazing proxies. Importantly for predictions of ecosystem response to temperature change, we found that pasture-level and plot-level favorability interacted: perennial grasses had a higher plot-level cover on cooler slopes, and this difference across topography was starkest in pastures that were less favorable for perennial grasses regionally. Understanding the mechanisms behind cross-scale interactions and contingent responses of vegetation to grazing in these increasingly invaded ecosystems will be critical to land management in a changing world.

Decreased air quality shows minimal influence on peak summer attendance at forested Pacific West national parks.

Wildfires are increasing in duration and intensity across the United States' Pacific West region, resulting in heightened particulate matter from smoke in the atmosphere. Levels of peak particulate matter are concurrent to peak visitor attendance at National Parks, given seasonal alignment with summer vacation travel and heightened forest fire conditions. Particulate matter threatens visitor health and safety and contributes to poor visibility and a deteriorated visitor experience. To assess visitation response to diminished air quality, we utilized wildfire-generated particulate matter (PM2.5) data in conjunction with monthly attendance records for three ecoregions containing eight national parks in Washington, Oregon, and California from 2009 to 2019. We analyzed daily PM2.5 levels from data gridded at the 10 km scale for National Park Service units by Level III forest ecoregions within the National Park Service's Pacific West Unit. Data were then compared to normalized monthly visitation trends for each of the ecoregions using two statistical methods Kendall's Tau and Analysis of Variance (ANOVA) with post-hoc Tukey tests. Results demonstrate that attendance at these national parks does not decrease in response to increased PM2.5 levels. Instead, we see several statistically significant increases in attendance across these ecoregions during periods of reduced air quality. Of 115 shifts between air quality categories during the busy season of July to September, there are no significant decreases in attendance as air quality worsens. These findings suggest that visitors are willing to tolerate reduced air quality compared to other factors such as temperature or precipitation. Given that park units within each ecoregion feature diverse historical contexts, varied built environments, and unique ecological systems, our discussion specifically addresses managerial concerns associated with maintained high levels of visitation during suboptimal, and potentially dangerous, conditions. There is substantial need for specific, scalable approaches to mitigate adverse health and experiential impacts as visitors are exposed to increased risks during a range of exertional activities associated with diverse settings.

Exploring indirect effects of a classic trophic cascade between urchins and kelp on zooplankton and whales.

Kelp forest trophic cascades have been extensively researched, yet indirect effects to the zooplankton prey base and gray whales have not been explored. We investigate the correlative patterns of a trophic cascade between bull kelp and purple sea urchins on gray whales and zooplankton in Oregon, USA. Using generalized additive models (GAMs), we assess (1) temporal dynamics of the four species across 8 years, and (2) possible trophic paths from urchins to kelp, kelp as habitat to zooplankton, and kelp and zooplankton to gray whales. Temporal GAMs revealed an increase in urchin coverage, with simultaneous decline in kelp condition, zooplankton abundance and gray whale foraging time. Trophic path GAMs, which tested for correlations between species, demonstrated that urchins and kelp were negatively correlated, while kelp and zooplankton were positively correlated. Gray whales showed nuanced and site-specific correlations with zooplankton in one site, and positive correlations with kelp condition in both sites. The negative correlation between the kelp-urchin trophic cascade and zooplankton resulted in a reduced prey base for gray whales. This research provides a new perspective on the vital role kelp forests may play across multiple trophic levels and interspecies linkages.

Effective dispersal patterns in prairie plant species across human-modified landscapes.

Effective dispersal among plant populations is dependent on vector behaviour, landscape features and availability of adequate habitats. To capture landscape feature effects on dispersal, studies must be conducted at scales reflecting single-generation dispersal events (mesoscale). Many studies are conducted at large scales where genetic differentiation is due to dispersal occurring over multiple generations, making it difficult to interpret the effects of specific landscape features on vector behaviour. Genetic structure at the mesoscale may be determined by ecological and evolutionary processes, such as the consequences of vector behaviour on patterns of gene flow. We used chloroplast haplotypes and nuclear genome SNP surveys to identify landscape features influencing seed and pollen dispersal at a mesoscale within the Rogue River Valley in southern Oregon. We evaluated biotic and abiotic vector behaviour by contrasting two annual species with differing dispersal mechanisms; Achyrachaena mollis (Asteraceae) is a self-pollinating and anemochoric species, and Plectritis congesta (Caprifoliaceae) is biotically pollinated with barochoric seeds. Using landscape genetics methods, we identified features of the study region that conduct or restrict dispersal. We found chloroplast haplotypes were indicative of historic patterns of gene flow prior to human modification of landscapes. Seed dispersal of A. mollis was best supported by models of isolation by distance, while seed-driven gene flow of P. congesta was determined by the distribution of preserved natural spaces and quality habitat. Nuclear genetic structure was driven by both pollen and seed dispersal, and both species responded to contemporary landscape changes, such as urban and agricultural conversion, and habitat availability.

Hospital Facility Prices Declined As A Result Of Oregon's Hospital Payment Cap.

Hospital prices for commercially insured people are high and vary widely, prompting states to seek ways to control hospital price growth. In October 2019, the Oregon state employee health insurance plan instituted a cap on hospital payments. Using 2014-21 data from the Oregon All Payer All Claims Reporting Program database, we performed a difference-in-differences analysis to test the impact of the cap on hospital facility prices for Oregon's state employee plan enrollees. We found that the cap was not associated with a significant reduction in inpatient facility prices across the post period (-$901.9 per admission) but was associated with a significant reduction in the second year after implementation (-$2,774.20). The cap was associated with a significant reduction in outpatient facility prices over the course of the first twenty-seven months of the policy (-$130.50 per procedure). We estimated $107.5 million (or 4 percent of total plan spending) in savings to the state employee plan during the first two years. The hospital payment cap successfully reduced hospital prices for enrollees in that plan.

Relation between the relative abundance and collapse of Aphanizomenon flos-aquae and microbial antagonism in Upper Klamath Lake, Oregon.

Aphanizomenon flos-aquae (AFA) is the dominant filamentous cyanobacterium that develops into blooms in Upper Klamath Lake, Oregon, each year. During AFA bloom and collapse, ecosystem conditions for endangered Lost River and shortnose suckers deteriorate, thus motivating the need to identify processes that limit AFA abundance and decline. Here, we investigate the relations between AFA and other members of the microbial community (photosynthetic and nonphotosynthetic bacteria and archaea), how those relations impact abundance and collapse of AFA, and the types of microbial conditions that suppress AFA. We found significant spatial variation in AFA relative abundance during the 2016 bloom period using 16S rRNA sequencing. The Pelican Marina site had the lowest AFA relative abundance, and this was coincident with increased relative abundance of Candidatus Sericytochromatia, Flavobacterium, and Rheinheimera, some of which are known AFA antagonists. The AFA collapse coincided with phosphorus limitation relative to nitrogen and the increased relative abundance of Cyanobium and Candidatus Sericytochromatia, which outcompete AFA when dissolved inorganic nitrogen is available. The data collected in this study indicate the importance of dissolved inorganic nitrogen combined with microbial community structure in suppressing AFA abundance.

Prenatal opioid use as a predictor of postpartum suicide attempts among reproductive-age women enrolled in Oregon Medicaid.

BACKGROUND: The rates of suicide and opioid use disorder (OUD) among pregnant and postpartum women continue to increase. This research characterized OUD and suicide attempts among Medicaid-enrolled perinatal women and examined prenatal OUD diagnosis as a marker for postpartum suicide attempts. METHODS: Data from Oregon birth certificates, Medicaid eligibility and claims files, and hospital discharge records were linked and analyzed. The sample included Oregon Medicaid women aged 15-44 who became pregnant and gave live births between January 2008 and January 2016 (N = 61,481). Key measures included indicators of suicide attempts (separately for any means and opioid poisoning) and OUD diagnosis, separately assessed during pregnancy and the one-year postpartum period. Probit regression was used to examine the overall relationship between prenatal OUD diagnosis and postpartum suicide attempts. A simultaneous equations model was employed to explore the link between prenatal OUD diagnosis and postpartum suicide attempts, mediated by postpartum OUD diagnosis. RESULTS: Thirty-three prenatal suicide attempts by any means were identified. Postpartum suicide attempts were more frequent with 58 attempts, corresponding to a rate of 94.3 attempts per 100,000. Of these attempts, 79% (46 attempts) involved opioid poisoning. A total of 1,799 unique women (4.6% of the sample) were diagnosed with OUD either during pregnancy or one-year postpartum with 53% receiving the diagnosis postpartum. Postpartum suicide attempts by opioid poisoning increased from 55.5 per 100,000 in 2009 to 105.1 per 100,000 in 2016. The rate of prenatal OUD also almost doubled over the same period. Prenatal OUD diagnosis was associated with a 0.15%-point increase in the probability of suicide attempts by opioid poisoning within the first year postpartum. This increase reflects a three-fold increase compared to the rate for women without a prenatal OUD diagnosis. A prenatal OUD diagnosis was significantly associated with an elevated risk of postpartum suicide attempts by opioid poisoning via a postpartum OUD diagnosis. CONCLUSIONS: The risk of suicide attempt by opioid poisoning is elevated for Medicaid-enrolled reproductive-age women during pregnancy and postpartum. Women diagnosed with prenatal OUD may face an increased risk of postpartum suicides attempts involving opioid poisoning.

Patients' Perspectives on Discontinuing Buprenorphine for the Treatment of Opioid Use Disorder.

OBJECTIVES: Buprenorphine and other medications for opioid use disorder (OUD) are recommended as standard of care in the treatment of OUD and are associated with positive health and addiction-related outcomes. Despite benefits, discontinuation is common, with half of patients discontinuing in the first year of treatment. Addressing OUD is a major clinical priority, yet little is known about the causes of medication discontinuation from the patient perspective. METHODS: From March 2021 to April 2022, we conducted qualitative interviews with patients who had discontinued buprenorphine for the treatment of OUD within the past 12 months. Eligible participants were selected from 2 Veterans Health Administration Health Care Systems in Oregon. Coding and analysis were guided by conventional qualitative content analysis. RESULTS: Twenty participants completed an interview; 90% were White and 90% were male, and the mean age was 54.2 years. Before discontinuation, participants had received buprenorphine for 8.3 months on average (range, 1-40 months); 80% had received buprenorphine for less than 12 months. Qualitative analysis identified the following themes relating to discontinuation: health system barriers (eg, logistical hurdles, rules and policy violations), medication effects (adverse effects; attributed adverse effects, lack of efficacy in treating chronic pain) and desire for opioid use. Patient description of decisions to discontinue buprenorphine could be multicausal, reflecting provider or system-level barriers in interaction with patient complexity or medication ambivalence. CONCLUSIONS: Study results identify several actionable ways OUD treatment could be modified to enhance patient retention.
