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.

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.

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.

The Association Between Prenatal Food Insecurity and Breastfeeding Initiation and Exclusive Breastfeeding Duration: A Longitudinal Study Using Oregon PRAMS and PRAMS-2, 2008-2015.

Background: In the United States, 11.1% of households experience food insecurity; however, pregnant women are disproportionately affected. Maternal food insecurity may affect infant feeding practices, for example, through being a source of chronic stress that may alter the decision to initiate and continue breastfeeding. Thus, we sought to determine whether prenatal food insecurity was associated with breastfeeding (versus not) and exclusive breastfeeding duration among Oregon women. Method: The Oregon Pregnancy Risk Assessment Monitoring System (PRAMS) data of live births from 2008 to 2015 and the Oregon PRAMS-2 follow-up survey were used (n = 3,624) in this study. Associations with breastfeeding initiation and duration were modeled with multivariable logistic regression and accelerated failure time (AFT), respectively. Models were adjusted for maternal sociodemographic and pre-pregnancy health characteristics. Results: Nearly 10% of women experienced prenatal food insecurity. For breastfeeding initiation, unadjusted models suggested non-significant decreased odds (odds ratio (OR) 0.88 [confidence intervals (CI): 0.39, 1.99]), whereas adjusted models revealed a non-significant increased odds (OR 1.41 [CI: 0.58, 3.47]). Unadjusted AFT models suggested that food-insecure mothers had a non-significant decrease in exclusive breastfeeding duration (OR 0.76 [CI: 0.50, 1.17]), but adjustment for covariates attenuated results (OR 0.89 [CI: 0.57, 1.39]). Conclusions: Findings suggest minimal differences in breastfeeding practices when exploring food security status in the prenatal period, though the persistence of food insecurity may affect exclusive breastfeeding duration. Lower breastfeeding initiation may be due to other explanatory factors correlated with food insecurity and breastfeeding, such as education and marital status.

Unhealthy air quality secondary to wildfires is associated with lower blastocyst yield.

OBJECTIVE: To study the impact of unhealthy air quality from the 2020 Oregon wildfires on outcomes for patients undergoing in vitro fertilization (IVF) treatment. DESIGN: A retrospective cohort study. SETTING: A university-based fertility clinic. PATIENTS: Subjects were undergoing IVF treatment from the 6 weeks preceding the wildfires through a 10-day exposure period. Cohorts were classified on the basis of whether subjects experienced patient and/or laboratory exposure to unhealthy air quality. Patient exposure was defined as at least 4 days of ovarian stimulation overlapping with the exposure, and laboratory exposure was defined as at least 2 days of IVF treatment and embryogenesis overlapping with the exposure. The unexposed cohort consisted of remaining subjects without defined exposure, with cycles in the 6 weeks preceding the wildfires. As some subjects had dual exposure and appeared in both patient and laboratory exposure cohorts, each cohort was separately compared with the unexposed control cohort. INTERVENTION: A 10-day period of unhealthy air quality caused by smoke plumes from a wildfire event. MAIN OUTCOME MEASURES: The primary outcome was the blastulation rate. Secondary outcomes included fertilization rate, number of blastocysts obtained, and cycles with no blastocysts frozen or transferred. RESULTS: Sixty-nine subjects underwent ovarian stimulation and IVF treatment during the 6 weeks preceding the wildfires through the 10-day period of unhealthy air quality. Of these, 15 patients were in the laboratory exposure cohort, 16 were in the patient exposure cohort, and 44 were unexposed. Six subjects appeared in both laboratory and patient exposure cohorts. Although neither exposure cohort had significantly decreased blastulation rate compared with the unexposed, the median number of blastocysts obtained was significantly lower in the laboratory exposure cohort than the unexposed group (2 [range 0-14] vs. 4.5 [range 0-21], respectively). The laboratory exposure cohort had significantly more cycles with no blastocysts obtained (3/15 [20%] vs. 1/44 [2%]). There were no significant differences in IVF treatment outcomes between patient exposure and unexposed cohorts. These findings persisted after controlling for age. There were no significant differences in pregnancy outcomes observed after embryo transfer between the exposure group and the unexposed group. CONCLUSION: For a cohort of patients undergoing IVF treatment, an acute episode of outside wildfire smoke exposure during fertilization and embryogenesis was associated with decreased blastocyst yield.

Predictors of Viral Suppression Among People Living with HIV in Rural Oregon.

With recent outbreaks of HIV in rural areas of the United States, it has become increasingly important to understand the factors affecting health outcomes of people with HIV living in rural areas. We assessed predictors of durable HIV viral suppression among rural participants using a pooled 7-year dataset from the Medical Monitoring Project (MMP), a cross-sectional, representative sample of individuals receiving HIV medical care in Oregon. Only 77.3% of rural participants achieved durable HIV viral suppression, while 22.7% had at least one detectable HIV viral load measurement within the past 12 months. The primary predictors of viral suppression were ARV adherence, poverty, and reported heavy drinking in the past 30 days. These results highlight the influence of social factors on health outcomes for persons with HIV living in rural areas and inform areas for policy and program change.

RESUMEN: Con los brotes recientes de VIH en áreas rurales de los Estados Unidos, se ha vuelto cada vez más importante comprender los factores que afectan los resultados de salud de las personas con VIH que viven en áreas rurales. Evaluamos los predictores de la supresión viral del VIH duradera entre los participantes rurales utilizando un conjunto de datos combinados de siete años del Proyecto de Monitoreo Médico (MMP), una muestra transversal y representativa de personas que reciben atención médica para el VIH en Oregón. Solo el 77,3% de los participantes rurales logró una supresión viral del VIH duradera, mientras que el 22,7% tuvo al menos una medición detectable de la carga viral del VIH en los últimos 12 meses. Los predictores primarios de la supresión viral fueron la adherencia a los ARV, la pobreza y el consumo excesivo de alcohol informado en los últimos 30 días. Estos resultados destacan la influencia de los factores sociales en los resultados de salud de las personas con VIH que viven en áreas rurales e informan las áreas para el cambio de políticas y programas.

Correlates of healthcare-seeking behavior for acute gastroenteritis-United States, October 1, 2016 -September 30, 2017.

BACKGROUND: In the United States, public health surveillance systems often underestimate the burden of acute gastroenteritis (AGE) because they only identify disease among those who interact with the healthcare system. OBJECTIVE: To identify factors associated with healthcare-seeking behavior among individuals experiencing community-acquired AGE. METHODS: From October 2016 -September 2017, we conducted a weekly, age-stratified, random sample of Kaiser Permanente Northwest members located in northwest Oregon and southwest Washington, United States. Individuals who completed the online survey and experienced AGE were included in the analysis. Univariate and multivariable logistic regressions were performed to identify predictors of healthcare-seeking behavior. RESULTS: Of the 3,894 survey respondents, 395 experienced an AGE episode and were eligible for analysis, of whom, 82 (21%) sought care for their AGE episode. In the final multivariable model, individuals with a concurrent fever (odds ratio [OR]: 4.76, 95% confidence interval [95% CI]: 2.48-9.13), increased diarrhea duration (≥6 days vs 1-4 days, OR: 4.22, 95% CI: 1.78-10.03), or increased vomiting duration (≥3 days vs 1 days, OR: 2.97, 95% CI: 1.22-7.26), were significantly more likely to seek healthcare. In the adjusted model, no sociodemographic or chronic disease variables were associated with healthcare-seeking behavior. CONCLUSION: These findings suggest that individuals with a short duration of AGE and those without concurrent fever are underrepresented in healthcare facility-based surveillance systems.

One-Year Association of Drug Possession Law Change With Fatal Drug Overdose in Oregon and Washington.

Importance: Two states modified laws to remove or substantially reduce criminal penalties for any drug possession. The hypothesis was that removing criminal penalties for drug possession may reduce fatal drug overdoses due to reduced incarceration and increased calls for help at the scene of an overdose. Objective: To evaluate whether decriminalization of drug possession in Oregon and Washington was associated with changes in either direction in fatal drug overdose rates. Design, Setting, and Participants: This cohort study used a synthetic control method approach to examine whether there were changes in drug possession laws and fatal drug overdose rates in Oregon and Washington in the postpolicy period (February 1, 2021, to March 31, 2022, in Oregon and March 1, 2021, to March 31, 2022, in Washington). A counterfactual comparison group (synthetic controls) was created for Oregon and Washington, using 48 states and the District of Columbia, that did not implement similar policies during the study period (January 1, 2018, to March 31, 2022). For 2018-2021, final multiple cause-of-death data from the National Vital Statistics System (NVSS) were used. For 2022, provisional NVSS data were used. Drug overdose deaths were identified using International Statistical Classification of Diseases and Related Health Problems, 10th Revision underlying cause-of-death codes X40-X44, X60-X64, X85, and Y10-Y14. Exposures: In Oregon, Measure 110 went into effect on February 1, 2021. In Washington, the Washington Supreme Court decision in State v Blake occurred on February 25, 2021. Main Outcome: Monthly fatal drug overdose rates. Results: Following the implementation of Measure 110, absolute monthly rate differences between Oregon and its synthetic control were not statistically significant (probability = 0.26). The average rate difference post Measure 110 was 0.268 fatal drug overdoses per 100 000 state population. Following the implementation of the policy change in Washington, the absolute monthly rate differences between Washington and synthetic Washington were not statistically significant (probability = 0.06). The average rate difference post Blake was 0.112 fatal drug overdoses per 100 000 state population. Conclusions and Relevance: This study found no evidence of an association between legal changes that removed or substantially reduced criminal penalties for drug possession in Oregon and Washington and fatal drug overdose rates. Additional research could examine potential other outcomes as well as longer-term associations with fatal drug overdose overall and across racial and ethnic groups.

Preventive dental care utilization and dental caries for Medicaid-enrolled adolescents in Oregon.

OBJECTIVES: This study aimed to evaluate the relationship between preventive dental care utilization and untreated dental caries for Medicaid-enrolled adolescents and to determine if the relationship is moderated by chronic conditions (CC). METHODS: This analysis was based on 2015-2016 Medicaid claims files and survey data collected from adolescents ages 12-18 years enrolled in Oregon Medicaid, who received a dental screening between December 2015 and December 2016 (n = 240). To assess the relationship between preventive dental care utilization and untreated dental caries (defined as decayed tooth surfaces), prevalence ratios (PR) and 95% confidence intervals (CI) were generated using log-linear regression models. We also tested for an interaction between preventive dental care utilization and CC. RESULTS: About 60.4% of adolescents utilized preventive dental care, 21.7% had CC, and 29.6% had ≥1 decayed tooth surfaces. There were no significant differences in untreated dental caries between adolescents who did and did not utilize preventive dental care (PR: 0.73, 95% CI: 0.33-1.60; p = 0.43). There was not a significant interaction between preventive dental care utilization and CC (p = 0.65). Preventive dental care utilization was not significantly associated with untreated dental caries for adolescents with CC (PR: 0.51, 95% CI: 0.10-2.65; p = 0.42) nor among adolescents without CC (PR: 0.79, 95% CI: 0.33-1.91; p = 0.61). CONCLUSIONS: Preventive dental care was not shown to be associated with lower untreated dental caries for Medicaid-enrolled adolescents or those with CC. Future work that is adequately powered should continue to elucidate this relationship in Medicaid enrollees.

Changes in arrests following decriminalization of low-level drug possession in Oregon and Washington.

BACKGROUND: Despite evidence that the U.S. "War on Drugs" is associated with increases in drug-related harm and other negative outcomes, all U.S. states have long criminalized most drug possession. In early 2021, both Oregon and Washington became exceptions to this rule when they fully (Oregon) or partially (Washington) decriminalized possession of small amounts of all drugs. METHODS: We obtained arrest data for 2019 to 2021 for intervention states (Oregon and Washington) and control states (Colorado, Idaho, Montana, and Nevada). We calculated monthly rates for arrests overall and for violent crimes, drug possession, equipment possession, non-drug crimes, and a set of low-level crimes termed displaced arrests. Using an interrupted time series analysis, we examined changes in monthly arrest rates after the implementation of policy change in Oregon and Washington compared to control states. RESULTS: In Oregon, there were 3 fewer drug possession arrests per 100,000 in the month after the policy change; the rate decreased throughout the post-implementation period. In Washington, there were almost 5 fewer drug possession arrests per 100,000 in the month following policy change, and the rate remained stable thereafter. Both declines were significantly greater than in comparison states. There were also statistically significant reductions in arrests for possession of drug equipment in Washington and a significant increase in displaced arrests in Oregon. There were no significant changes in overall arrests, non-drug arrests or arrests for violent crime in either state, relative to controls. CONCLUSION: This analysis demonstrates that it is possible for state drug decriminalization policies to dramatically reduce arrests for drug possession without increasing arrests for violent crimes, potentially reducing harm to people who use drugs and their communities. Additional research is needed to determine whether these legal reforms were associated with changes in overdose rates and other drug-related harms.

Does drug decriminalization increase unintentional drug overdose deaths?: Early evidence from Oregon Measure 110.

This paper evaluates the causal effect of drug decriminalization on unintentional drug overdose deaths in a context with relatively poor access to drug treatment services. Using the synthetic control method, I find that when Oregon decriminalized small amounts of drugs in February 2021, it caused 182 additional unintentional drug overdose deaths to occur in Oregon in 2021. This represents a 23% increase over the number of unintentional drug overdose deaths predicted if Oregon had not decriminalized drugs.

Pediatric SARS-CoV-2 Seroprevalence, Oregon, USA, November 1, 2020-June 30, 2022.

We estimated SARS-CoV-2 seroprevalence in children in Oregon, USA, at 6 time points. Seroprevalence increased linearly during November 2020-December 2021 and peaked in February 2022 at 38.8% (95% CI 32.8%-46.5%). We observed no increase in the seroprevalence trend after widespread school reopening. Seroprevalence estimates complement case-based cumulative incidence.

The Impacts of Politicization on Public Health Workers: The COVID-19 Pandemic in Oregon and Montana.

CONTEXT: The contributions from the field of public health to human society are numerous and are often taken for granted. The COVID-19 pandemic thrust the largely invisible public health workforce into the public eye. Like other career civil servants at the intersection of the citizen-state encounter, reports of uncooperative, hostile, and even violent confrontations between public health workers and those they serve are on the rise. This study explores the attitudes of public health professionals in two states in the American West. METHODS: The authors conducted an anonymous web-based survey of public health professionals in Montana and Oregon one year into the COVID-19 pandemic. FINDINGS: Public health workers who responded to the survey reported beliefs that the COVID-19 pandemic was politicized by actors in the government, both major political parties, the media, and the public broadly. This politicization affected workers' abilities to do their jobs, with respondents in Montana experiencing more negative impacts than those in Oregon. CONCLUSIONS: Public health workers face growing antagonism from the public and pressure from political leaders, which poses a significant concern for the public health workforce and for communities as they prepare to address and overcome future public health challenges.

Population screening shows risk of inherited cancer and familial hypercholesterolemia in Oregon.

The Healthy Oregon Project (HOP) is a statewide effort that aims to build a large research repository and influence the health of Oregonians through providing no-cost genetic screening to participants for a next-generation sequencing 32-gene panel comprising genes related to inherited cancers and familial hypercholesterolemia. This type of unbiased population screening can detect at-risk individuals who may otherwise be missed by conventional medical approaches. However, challenges exist for this type of high-throughput testing in an academic setting, including developing a low-cost high-efficiency test and scaling up the clinical laboratory for processing large numbers of samples. Modifications to our academic clinical laboratory including efficient test design, robotics, and a streamlined analysis approach increased our ability to test more than 1,000 samples per month for HOP using only one dedicated HOP laboratory technologist. Additionally, enrollment using a HIPAA-compliant smartphone app and sample collection using mouthwash increased efficiency and reduced cost. Here, we present our experience three years into HOP and discuss the lessons learned, including our successes, challenges, opportunities, and future directions, as well as the genetic screening results for the first 13,670 participants tested. Overall, we have identified 730 pathogenic/likely pathogenic variants in 710 participants in 24 of the 32 genes on the panel. The carrier rate for pathogenic/likely pathogenic variants in the inherited cancer genes on the panel for an unselected population was 5.0% and for familial hypercholesterolemia was 0.3%. Our laboratory experience described here may provide a useful model for population screening projects in other states.

Commercial Fishing Fatalities and Injuries Described by Linked Vessel Incidents.

OBJECTIVES: The Risk Information System for Commercial Fishing (RISC Fishing) merged information on fishermen and vessel incident types from various databases. This descriptive study examined linked fisherman injury records (fatal and nonfatal) and vessel incident records in Oregon and Washington from 2000 to 2018 in the RISC Fishing database. The circumstances of incidents and any association with fishermen outcomes were explored to identify injury prevention opportunities. METHODS: The statistical analyses included a descriptive study of incidents related to the injury characteristics and frequency of outcomes by incident type. Further analyses included contingency tables and Pearson Chi-Square tests for selected variables to determine if there were associations between vessel incident outcomes (fatality, nonfatal injury, no injury). RESULTS: A total of 375 reported incidents with 93 cases of fatalities, 239 nonfatal injuries, and over 6,575 fishermen with no injury were described. Of fatalities, 90% were due to drowning, with only 2% of victims reported donning survival equipment. Deckhands experienced fatal and nonfatal injuries most frequently. The most common factors associated with nonfatal injuries included contact with objects (event), walking on vessel and hauling gear (work activities), and fractures and open wounds (nature). The most common final event leading to a vessel disaster with no injury being reported was sinking (76%). Distributions between the incident outcomes (fatality, nonfatal injury, and no injury) differed by vessel activity/type, fishery/gear, and event leading to the incident. CONCLUSION: Linked information of fishermen injury outcomes and vessel incident information showed that events and settings that involve fatalities are qualitatively different from incidents resulting in only nonfatal injuries or uninjured survivors. Vessel-level approaches for mitigating fatalities, such as ensuring vessel stability, improving navigation/operation decisions, and spotlighting survival equipment policies/rescue priorities could have a significant impact. Work task-specific prevention strategies for nonfatal injuries related to the larger vessels (catcher/processors and processors) and smaller vessels (with pot/trap gears) are paramount. The use of linked information provided in reports can provide a fuller incident picture to advance efforts to improve the working conditions of commercial fishermen.

Epidemiology of Pulmonary and Extrapulmonary Nontuberculous Mycobacteria Infections at 4 US Emerging Infections Program Sites: A 6-Month Pilot.

BACKGROUND: Nontuberculous mycobacteria (NTM) cause pulmonary (PNTM) and extrapulmonary (ENTM) disease. Infections are difficult to diagnose and treat, and exposures occur in healthcare and community settings. In the United States, NTM epidemiology has been described largely through analyses of microbiology data from health departments, electronic health records, and administrative data. We describe findings from a multisite pilot of active, laboratory- and population-based NTM surveillance. METHODS: The Centers for Disease Control and Prevention's Emerging Infections Program conducted NTM surveillance at 4 sites (Colorado, 5 counties; Minnesota, 2 counties; New York, 2 counties; and Oregon, 3 counties [PNTM] and statewide [ENTM]) from 1 October 2019 through 31 March 2020. PNTM cases were defined using published microbiologic criteria. ENTM cases required NTM isolation from a nonpulmonary specimen, excluding stool and rectal swabs. Patient data were collected via medical record review. RESULTS: Overall, 299 NTM cases were reported (PNTM: 231, 77%); Mycobacterium avium complex was the most common species group. Annualized prevalence was 7.5/100 000 population (PNTM: 6.1/100 000; ENTM: 1.4/100 000). Most patients had signs or symptoms in the 14 days before positive specimen collection (ENTM: 62, 91.2%; PNTM: 201, 87.0%). Of PNTM cases, 145 (62.8%) were female and 168 (72.7%) had underlying chronic lung disease. Among ENTM cases, 29 (42.6%) were female, 21 (30.9%) did not have documented underlying conditions, and 26 (38.2%) had infection at the site of a medical device or procedure. CONCLUSIONS: Active, population-based NTM surveillance will provide data for monitoring the burden of disease and characterize affected populations to inform interventions.

The Ongoing Impact of COVID-19 on Testing for and Diagnoses of HIV and Bacterial Sexually Transmitted Infections in Oregon.

BACKGROUND: The COVID-19 pandemic has disrupted HIV and sexually transmitted infection (STI) testing accessibility. We sought to assess the longer-term impacts of COVID-19 on HIV and STI testing and diagnosis in Oregon. METHODS: First, we examined HIV, Neisseria gonorrhoeae / Chlamydia trachomatis (CT), and syphilis tests conducted at the Oregon State Public Health Laboratory (public sector) and a large commercial laboratory (private sector) and HIV, N. gonorrhoeae , CT, and primary and secondary (P&S) syphilis diagnoses in Oregon from January 1, 2019, to December 31, 2021. We compared monthly testing and diagnosis rates in 5 prespecified periods: pre-COVID-19 (January 2019-February 2020), stay-at-home order (March 2020-May 2020), reopening (June 2020-December 2020), vaccine availability (January 2021-June 2021), and Delta/early Omicron spread (July 2021-December 2021). Second, we calculated the number of HIV and STI diagnoses per test in the public and private sectors. Finally, we used seasonal autoregressive integrated moving average models to predict expected HIV and STI diagnoses for comparison to those observed. RESULTS: Both public and private sector HIV and bacterial STI testing fell to nadirs in April 2020 with incomplete recovery to 2019 levels by the close of 2021. Compared with pre-COVID-19, public sector and private sector testing was significantly lower in all subsequent periods. Compared with pre-COVID-19, P&S syphilis cases were 52%, 75%, and 124% greater in the reopening, vaccine availability, and Delta/early Omicron periods, respectively. From March 2020 to December 2021, we observed an excess of P&S syphilis cases (+37.1%; 95% confidence interval, 22.2% to 52.1%) and a deficit in CT cases (-10.7%; 95% confidence interval, -15.4% to -6.0%). CONCLUSIONS: By December 2021, HIV/STI testing had not recovered to pre-COVID-19 levels, and HIV/STI continues to be underdiagnosed. Despite decreased testing, P&S syphilis cases have increased substantially.

Veteran suicide and associated community characteristics in Oregon.

Developing a public health approach to suicide prevention among United States (US) military veterans requires additional data and guidance on where, when, for whom, and what prevention resources should be deployed. This study examines veteran suicide mortality across one US state (Oregon) to identify county-level "hotspots" for veteran suicide, identify community characteristics associated with increased suicide among veterans, and examine excess spatial risk after accounting for space, time, and community characteristics. We linked Oregon mortality data with VA databases to identify veterans who had resided in Oregon and died by suicide between January 1, 2009 and December 31, 2018 (n = 1727). Community characteristic data were gathered at the county level from publicly available datasets on social determinants of health known to be associated with poor health outcomes, including suicide risk. We estimated spatial generalized linear mixed models for the full 10-year period and for each 5-year period using integrated nested Laplace approximation with county as the higher hierarchy. Smoothed standardized mortality ratios were used to identify counties with higher risk of veteran suicide. We found a small clustering of counties in the southwestern corner of Oregon that held the highest risk for veteran suicide across the ten years studied. In multivariable models, higher prevalence of unmarried persons was the only community measure significantly associated with increased veteran suicide risk. However, social contextual factors as a group, along with geographic space, explained most risk for suicide among veterans at the population level.

Human immunodeficiency virus pre-exposure prophylaxis awareness among people who inject drugs in Portland, Oregon.

BACKGROUND: Pre-Exposure Prophylaxis (PrEP) to prevent transmission of human immunodeficiency virus (HIV) among people who inject drugs (PWID) has demonstrated efficacy yet awareness of PrEP among PWID is low. METHODS: 2018 National Behavioral Health Survey data from the Portland, Oregon metropolitan statistical area was analyzed with chi-squared tests and generalized linear models to determine correlates of PrEP awareness among PWID. RESULTS: 80% of the sample had at least one indication for PrEP and 15% of the sample was aware of PrEP. Factors associated with higher PrEP awareness were: higher education level (PR = 1.083, CI = 1.018-1.153, p = .012), reporting transactional sex (PR = 1.154, CI = 1.019-1.307, p = .024), and men who have sex with men reporting condomless sex (PR = 1.376, CI = 1.081-1.752, p = .010). Lack of a usual source of care (PR = 0.884, CI = 0.824-0.949, p < .001) was negatively associated with PrEP awareness. CONCLUSIONS: Interventions to increase PrEP awareness need to target groups with particularly low awareness and be delivered in settings accessible to PWID.
