Opioid use and COVID-19: a secondary analysis of the impact of relaxation of methadone take-home dosing guidelines on use of illicit opioids.

Background: An exemption to existing U.S. regulation of methadone maintenance therapy after the onset of the COVID-19 pandemic permitted increased take-home doses beginning March 2020.Objectives: We assessed the impact of this exemption on opioid use.Methods: A pre/post study of 187 clients recruited from an OTP who completed a survey and consented to share their urine drug testing (UDT) data. Use of fentanyl, morphine, hydromorphone, codeine, and heroin was assessed via UDT. Receipt of take-home methadone doses was assessed from clinic records for 142 working days pre- and post-COVID exemption. Analysis was conducted using a linear regression model to assess the association between increased take-home doses and use of illicit opioids.Results: In the pre- vs. post-COVID-19 SAMHSA exemption periods, 26.2% vs. 36.3% of UDTs were positive for 6-acetylmorphine respectively, 32.6% vs. 40.6% positive for codeine, 34.2% vs 44.2% positive for hydromorphone, 39.5% vs. 48.1% positive for morphine, 8.0% vs. 14.4% positive for fentanyl (p-value < .001). However, in the unadjusted descriptive data, when grouped by change in substance use, those clients who experienced a decrease in the use of morphine, codeine, and heroin post-COVID-19 were given significantly more take-home doses than the groups that had no change or an increase in the use of these substances. In the adjusted model, there was no significant relationship between change in opioid use and increased receipt of take-home methadone doses.Conclusions: Although take-home doses post-COVID-19 nearly doubled, this increase was not associated with a significant change in use of illicit opioids.

Disparities in Access to Opioid Treatment Programs and Office-Based Buprenorphine Treatment Across the Rural-Urban and Area Deprivation Continua: A US Nationwide Small Area Analysis.

OBJECTIVES: To measure access to opioid treatment programs (OTPs) and office-based buprenorphine treatment (OBBTs) at the smallest geographic unit for which the Census Bureau publishes demographic and socioeconomic data (ie, block group) and to explore disparities in access to treatment across the rural-urban and area deprivation continua across the United States. METHODS: Access to OTPs and OBBTs at the block group in 2019 was quantified using an innovative 2-step floating catchment area technique that accounts for the supply of treatment facilities relative to the population size, proximity of facilities relative to the location of population in block groups, and time as a barrier within catchments. Block groups were stratified into tertiles based on the rural-urban continuum codes (metropolitan, micropolitan, small town, or rural) and area deprivation index (least-deprived, middle-deprived, most-deprived). The Integrated Nested Laplace Approximation approach was used for statistical analysis. RESULTS: Across the United States, 3329 block groups corresponding to 2 915 949 adults lacked access to OTPs within a 2-hour drive of their community and 130 block groups corresponding to 86 605 adults did not have access to OBBTs. Disparities in access to treatment were observed across the urban-rural and area deprivation continua including (1) lowest mean access score to OBBTs were found among most-deprived small towns, and (2) lower mean access score to OTPs were found among micropolitan and small towns. CONCLUSIONS: The results of this study revealed disparities in access to medication-assisted treatment. The findings call for creative initiatives and local and regional policies to develop to mitigate access problems.

Transport Time and Mortality in Critically Ill Patients with Severe Traumatic Brain Injury.

PURPOSE: Severe traumatic brain injury (TBI) is a major cause of morbidity and mortality in critically ill patients. Pre-hospital care and transportation time may impact their outcomes. METHODS: Using the British Columbia Trauma Registry, we included 2,860 adult (≥18 years) patients with severe TBI (abbreviated injury scale head score ≥4), who were admitted to an intensive care unit (ICU) in a centre with neurosurgical services from January 1, 2000 to March 31, 2013. We evaluated the impact of transportation time (time of injury to time of arrival at a neurosurgical trauma centre) on in-hospital mortality and discharge disposition, adjusting for age, sex, year of injury, injury severity score (ISS), revised trauma score at the scene, location of injury, socio-economic status and direct versus indirect transfer. RESULTS: Patients had a median age of 43 years (interquartile range [IQR] 26-59) and 676 (23.6%) were female. They had a median ISS of 33 (IQR 26-43). Median transportation time was 80 minutes (IQR 40-315). ICU and hospital length of stay were 6 days (IQR 2-12) and 20 days (IQR 7-42), respectively. Six hundred and ninety-six (24.3%) patients died in hospital. After adjustment, there was no significant impact of transportation time on in-hospital mortality (odds ratio 0.98, 95% confidence interval 0.95-1.01). There was also no significant effect on discharge disposition. CONCLUSIONS: No association was found between pre-hospital transportation time and in-hospital mortality in critically ill patients with severe TBI.

How Media Literacy and Science Media Literacy Predicted the Adoption of Protective Behaviors Amidst the COVID-19 Pandemic.

Individuals must navigate complex media environments filled with frequently changing and varyingly credible information to acquire and apply health information during times of uncertainty and danger. A process model tested in two U.S. national surveys in spring (N = 1220) and summer (N = 1264) of 2020 tested how three media literacy constructs (about sources, content, and science information) predicted the adoption of behaviors protective for COVID-19. Results showed that the three media literacy constructs were mediated by knowledge of COVID-19 (wave 1 TE = 0.190; wave 2 TE = 0.190) and expectancies (wave 1 TE = 0.496; wave 2 TE = 0.613). The model was confirmed as largely consistent across the two waves of data collection with independent samples. Results show the importance of expectancies for mediating the effects of media literacy, efficacy, and knowledge on behavior. The study suggests that media literacy and science media literacy skills aid health behavior adoption by contributing to knowledge gain and expectancies.

The impact of relaxation of methadone take-home protocols on treatment outcomes in the COVID-19 era.

BACKGROUND: Background: In response to the COVID-19 pandemic, the US Substance Abuse and Mental Health Services Administration (SAMHSA) allowed for an increase in methadone take-home doses for the treatment of Opioid Use Disorder (OUD) in March 2020. OBJECTIVE: To evaluate the effects of the SAMSHA exemption on methadone adherence and OUD-related outcomes. METHODS: A convenience sample of 183 clients (58% female) were recruited from a methadone clinic in the fall of 2019 for a cross-sectional survey. Survey data was linked to clinical records, including urine drug testing (UDT) results for methadone and emergency department (ED) visits at the local hospital. Participants were on stable methadone dosing for 9 months prior to and following March 2020. Methadone adherence was assessed by UDTs; OUD-related outcomes were assessed by overdose events and ED visits. Logistic regression was used to assess the association between change in take-home methadone doses and outcomes. RESULTS: Mean take-home doses increased nearly 200% (11.4 doses/30 days pre-COVID-19 vs. 22.3 post-SAMHSA exemption). ED visits dropped from 74 (40.4%) pre-COVID-19 to 56 (30.6%) post-SAMHSA exemption (p = <0.001). No significant changes were observed in either the number of clients experiencing overdose or those who experienced one or more methadone negative UDTs in the post-SAMHSA exemption period. Adjusted models did not show a significant association between changes in take-home doses and associated outcomes. CONCLUSIONS: Despite a near-doubling of take-home methadone doses during the COVID-19 exemption period, the increase in take-home doses was not associated with negative treatment outcomes in methadone-adherent clients.

The Association Between Obesity, Socio-Economic Status, and Neighborhood Environment: A Multi-Level Analysis of Spokane Public Schools.

Socio economic inequities in obesity have been attributed to individuals' psychosocial and behavioral characteristics. School environment, where children spend a large part of their day, may play an important role in shaping their health. This study aims to assess whether prevalence of overweight and obesity among elementary school students was associated with the school's social and built environments. Analyses were based on 28 public elementary schools serving a total of 10,327 children in the city of Spokane, Washington. Schools were classified by percentage of students eligible for free and reduced meals (FRM). Crime rates, density of arterial roads, healthy food access, and walkability were computed in a one-mile walking catchment around schools to characterize their surrounding neighborhood. In the unadjusted multilevel logistic regression analyses, age, sex, percentage of students eligible for FRM, crime, walkability, and arterial road exposure were individually associated with the odds of being overweight or obese. In the adjusted model, the odds of being overweight or obese were higher with age, being male, and percentage of students eligible for FRM. The results call for policies and programs to improve the school environment, students' health, and safety conditions near schools.

Spatial access to opioid treatment program and alcohol and cannabis outlets: analysis of missed doses of methadone during the first, second, and third 90 days of treatment.

Background: The burden of access to opioid treatment programs (OTPs) may change as clients become eligible for take-home privileges. Our previous study showed clients who lived more than 10-miles away from an OTP were more likely to miss methadone doses during the first 30 days of treatment. Proximity to alcohol and cannabis outlets may also negatively influence treatment adherence.Objective: To examine the association between access to this OTP, alcohol and cannabis outlets, and the number of missed methadone doses during the first, second, and third 90 days of treatment.Methods: The number of missed methadone doses was calculated for 752, 689, and 584 clients who remained in treatment, respectively, for at least 3, 6, and 9 months (50% female). Distance between client's home and the OTP, alcohol, and cannabis outlets was measured. Generalized linear models were employed.Results: Shorter distance from a client's residence to the OTP was associated with a decreased number of missed methadone doses during the first 90 days of treatment. Shorter distance to the closest cannabis retail outlet was associated with an increased number of missed methadone doses during the first and second 90 days of treatment. Shorter distance to the closest off-premise alcohol outlet was associated with an increased number of missed methadone doses during the third 90 days of treatment.Conclusions: Improving spatial accessibility of OTPs are essential to ensure treatment opportunities are available for individuals so affected. Exploring to what extent residing in areas that facilitate alcohol and cannabis availability can influence treatment adherence is warranted.

Barriers to Cervical Screening Among Sex Workers in Vancouver.

OBJECTIVES: We longitudinally examined the social, structural, and geographic correlates of cervical screening among sex workers in Metropolitan Vancouver, British Columbia, to determine the roles that physical and social geography play in routine reproductive health care access. METHODS: Analysis drew on (2010-2013) data from an open prospective cohort of sex workers (An Evaluation of Sex Workers' Health Access). We used multivariable logistic regression with generalized estimating equations (GEE) to model correlates of regular cervical screening. RESULTS: At baseline, 236 (38.6%) of 611 sex workers in our sample had received cervical screening, and 63 (10.3%) were HIV-seropositive. In multivariable GEE analysis, HIV-seropositivity (adjusted odds ratio [AOR] = 1.65; 95% confidence interval [CI] = 1.06, 2.58) and accessing outreach services (AOR = 1.35; 95% CI = 1.09, 1.66) were correlated with regular cervical screening. Experiencing barriers to health care access (e.g., poor treatment by health care staff, limited hours of operation, and language barriers) reduced odds of regular Papanicolaou testing (AOR = 0.81; 95% CI = 0.65, 1.00). CONCLUSIONS: Sex workers in Metropolitan Vancouver had suboptimal levels of cervical screening. Innovative mobile outreach service delivery models offering cervical screening as one component of sex worker-targeted comprehensive sexual and reproductive health services may hold promise.

Hypertrophic pyloric stenosis in the Maritimes: examining the waves of change over time.

BACKGROUND: Changing patterns of referral and management of pediatric surgical conditions, including hypertrophic pyloric stenosis (HPS), have recently been described and often relate to comfort with early nonoperative management, anesthesia and corrective surgery. Travelling distance required for treatment at pediatric centres can also be burdensome for families. We assessed referral patterns for HPS in the maritime provinces of Canada over 10 years to quantify the burden on families travelling for surgical care. METHODS: We reviewed the charts of all patients with HPS in the Maritimes. Length of hospital stay (LOS) and complication rates were analyzed in regards to resuscitation and management at a pediatric centre and/or peripheral centres. We used postal codes for each patient to track distance travelled for management. RESULTS: We assessed 751 cases of HPS. During the study period (Jan. 1, 2001-Dec. 31, 2010), referral to pediatric centres increased from 49% to 71%. Postoperative complications were 2.5-fold higher in peripheral centres. Infants referred to pediatric centres were 78% less likely to have an LOS longer than 3 days. Laparoscopic pyloromyotomy, which was performed only in pediatric centres, was associated with a shorter postoperative LOS. CONCLUSION: Our study supports the current literature demonstrating improved outcomes, shorter overall LOS and decreased risk of complications when infants with HPS are treated in pediatric centres. This should be considered when planning access to pediatric surgical resources.

CONTEXTE: Une évolution des tendances dans les pratiques d'orientation des patients et de prise en charge des affections pédiatriques nécessitant une intervention chirurgicale, telles que la sténose hypertrophique du pylore (SHP), a récemment été décrite; elle dépend souvent du degré d'acceptation de la prise en charge non chirurgicale précoce, de l'anesthésie et de la chirurgie correctrice. Le traitement en centre pédiatrique peut exiger des déplacements pénibles pour les familles. Nous avons évalué les pratiques d'orientation des cas de SHP dans les provinces maritimes du Canada sur une période de 10 ans pour quantifier l'ampleur du fardeau qui incombe aux familles devant voyager pour obtenir des soins chirurgicaux. MÉTHODES: Nous avons étudié le dossier de tous les patients atteints de SHP dans les Maritimes et avons comparé la durée de séjour et le taux de complications associés à la réanimation et à la prise en charge dans les centres pédiatriques et les centres périphériques. Nous avons aussi utilisé les codes postaux des patients pour déterminer la distance de déplacement des familles. RÉSULTATS: Nous avons analysé 751 cas de SHP. Pendant la période à l'étude (2001­2010), le taux d'orientation des patients vers les centres pédiatriques est passé de 49 % à 71 %. Les complications postopératoires étaient 2,5 fois plus courantes dans les centres périphériques, et les séjours de plus de 3 jours étaient 78 % moins fréquents chez les nourrissons traités en centre pédiatrique. La pyloromyotomie par laparoscopie, réalisée dans les centres pédiatriques seulement, a été associée à une réduction de la durée de séjour postopératoire. CONCLUSION: Notre étude va dans le même sens que la littérature actuelle, qui indique que le traitement des nourrissons atteints de SHP en centre pédiatrique est associé à de meilleurs résultats postchirurgicaux, à une durée d'hospitalisation moins longue et à un risque de complications plus faible que le traitement dans un centre périphérique. Ces résultats devraient être pris en compte dans la planification de l'accès aux ressources dans le domaine de la chirurgie pédiatrique.

A geospatial analysis of the relationship between neighbourhood socioeconomic status and adult severe injury in Greater Vancouver.

BACKGROUND: Every year, injuries cost the Canadian healthcare system billions of dollars and result in thousands of emergency room visits, hospitalisations and deaths. The purpose of this study was to explore the relationship between neighbourhood socioeconomic status (NSES) and the rates of all-cause, unintentional and intentional severe injury in Greater Vancouver adults. A second objective was to determine whether the identified associations were spatially consistent or non-stationary. METHODS: Severe injury cases occurring between 2001 and 2006 were identified using the British Columbia's Coroner's Service records and the British Columbia Trauma Registry, and mapped by census dissemination areas using a geographical information system. Descriptive statistics and exploratory spatial data analysis methods were used to gain a better understanding of the data sets and to explore the relationship between the rates of severe injury and two measures of NSES (social and material deprivation). Ordinary least squares and geographically weighted regression were used to model these relationships at the global and local levels. RESULTS: Inverse relationships were identified between both measures of NSES and the rates of severe injury with the strongest associations located in Greater Vancouver's most socioeconomically deprived neighbourhoods. Social deprivation was found to have a slightly stronger relationship with the rates of severe injury than material deprivation. CONCLUSIONS: Results of this study suggest that policies and programmes aimed at reducing the burden of severe injury in Greater Vancouver should take into account social and material deprivation, and should target the most socioeconomically deprived neighbourhoods in Greater Vancouver.

A comparative analysis of potential spatio-temporal access to palliative care services in two Canadian provinces.

BACKGROUND: Access to health services such as palliative care is determined not only by health policy but a number of legacies linked to geography and settlement patterns. We use GIS to calculate potential spatio-temporal access to palliative care services. In addition, we combine qualitative data with spatial analysis to develop a unique mixed-methods approach. METHODS: Inpatient health care facilities with dedicated palliative care beds were sampled in two Canadian provinces: Newfoundland and Saskatchewan. We then calculated one-hour travel time catchments to palliative health services and extended the spatial model to integrate available beds as well as documented wait times. RESULTS: 26 facilities with dedicated palliative care beds in Newfoundland and 69 in Saskatchewan were identified. Spatial analysis of one-hour travel times and palliative beds per 100,000 population in each province showed distinctly different geographical patterns. In Saskatchewan, 96.7% of the population living within a-1 h of drive to a designated palliative care bed. In Newfoundland, 93.2% of the population aged 65+ were living within a-1 h of drive to a designated palliative care bed. However, when the relationship between wait time and bed availability was examined for each facility within these two provinces, the relationship was found to be weak in Newfoundland (R(2) = 0.26) and virtually nonexistent in Saskatchewan (R(2) = 0.01). CONCLUSIONS: Our spatial analysis shows that when wait times are incorporated as a way to understand potential spatio-temporal access to dedicated palliative care beds, as opposed to spatial access alone, the picture of access changes.

Disparities in access to opioid treatment programs and buprenorphine providers by race and ethnicity in the contiguous U.S.

BACKGROUND: The burden of drug overdose mortality varies by race and ethnicity, with American Indian/Alaska Native (AI/AN), Black, and White people experiencing the largest burden. We analyzed census block group data to evaluate differences in travel distance to opioid treatment programs (OTP) and buprenorphine providers by race and ethnicity. METHODS: The Substance Abuse and Mental Health Services Administration provided the addresses of OTPs and buprenorphine providers. The study classified block groups as majority (≥50 %) AI/AN, Black, Asian, White, no single racial majority, or Hispanic. We classified deprivation and rurality using the Area Deprivation Index and Rural-Urban Commuting Area codes. The study applied generalized linear mixed models. RESULTS: Among all block groups, the median road distance to the nearest OTPs and buprenorphine providers was 8 and 2 miles, respectively. AI/AN-majority block groups had the longest median distances to OTPs (88 miles versus 4-10 miles) and buprenorphine providers (17 miles versus 1-3 miles) compared to other racial or ethnic majority block groups. For OTPs and buprenorphine providers, travel distances were slightly greater in more deprived block groups compared to less deprived block groups. The median distance to the nearest OTPs and buprenorphine providers were larger in micropolitan and small town/rural block groups compared to metropolitan areas. CONCLUSIONS: Disparities exist in travel distance to OTPs and buprenorphine providers. People in block groups with AI/AN-majority, nonmetropolitan, or more deprived designation experience travel disparities accessing treatment. Future research should develop targeted interventions to reduce access to care disparities for individuals with opioid use disorder.

Distance to endoscopy services amplifies racial inequities in colorectal cancer mortality in Washington state.

BACKGROUND: This study evaluates relationships among race, access to endoscopy services, and colorectal cancer (CRC) mortality in Washington state (WA). METHODS: We overlayed the locations of ambulatory endoscopy services with place of residence at time of death, using Department of Health data (2011-2018). We compared CRC mortality data within and outside a 10 â€‹km buffer from services. We used linear regression to assess the impact of distance and race on age at death while adjusting for gender and education level. RESULTS: Age at death: median 72.9y vs. 68.2y for white vs. non-white (p â€‹< â€‹0.001). The adjusted model showed that non-whites residing outside the buffer died 6.9y younger on average (p â€‹< â€‹0.001). Non-whites residing inside the buffer died 5.2y younger on average (p â€‹< â€‹0.001), and whites residing outside the buffer died 1.6y younger (p â€‹< â€‹0.001). We used heatmaps to geolocate death density. CONCLUSIONS: Results suggest that geographic access to endoscopy services disproportionately impacts non-whites in Washington. These data help identify communities which may benefit from improved access to alternative colorectal cancer screening methods.

Multidimensional Approach to Exploring Neighborhood Determinants and Symptom Severity Among Individuals With Psychosis.

Importance: The impact of cumulative exposure to neighborhood factors on psychosis, depression, and anxiety symptom severity prior to specialized services for psychosis is unknown. Objective: To identify latent neighborhood profiles based on unique combinations of social, economic, and environmental factors, and validate profiles by examining differences in symptom severity among individuals with first episode psychosis (FEP). Design, Setting, and Participants: This cohort study used neighborhood demographic data and health outcome data for US individuals with FEP receiving services between January 2017 and August 2022. Eligible participants were between ages 14 and 40 years and enrolled in a state-level coordinated specialty care network. A 2-step approach was used to characterize neighborhood profiles using census-tract data and link profiles to mental health outcomes. Data were analyzed March 2023 through October 2023. Exposures: Economic and social determinants of health; housing conditions; land use; urbanization; walkability; access to transportation, outdoor space, groceries, and health care; health outcomes; and environmental exposure. Main Outcomes and Measures: Outcomes were Community Assessment of Psychic Experiences 15-item, Patient Health Questionnaire 9-item, and Generalized Anxiety Disorder 7-item scale. Results: The total sample included 225 individuals aged 14 to 36 years (mean [SD] age, 20.7 [4.0] years; 152 men [69.1%]; 9 American Indian or Alaska Native [4.2%], 13 Asian or Pacific Islander [6.0%], 19 Black [8.9%], 118 White [55.1%]; 55 Hispanic ethnicity [26.2%]). Of the 3 distinct profiles identified, nearly half of participants (112 residents [49.8%]) lived in urban high-risk neighborhoods, 56 (24.9%) in urban low-risk neighborhoods, and 57 (25.3%) in rural neighborhoods. After controlling for individual characteristics, compared with individuals residing in rural neighborhoods, individuals residing in urban high-risk (mean estimate [SE], 0.17 [0.07]; P = .01) and urban low-risk neighborhoods (mean estimate [SE], 0.25 [0.12]; P = .04) presented with more severe psychotic symptoms. Individuals in urban high-risk neighborhoods reported more severe depression (mean estimate [SE], 1.97 [0.79]; P = .01) and anxiety (mean estimate [SE], 1.12 [0.53]; P = .04) than those in rural neighborhoods. Conclusions and Relevance: This study found that in a cohort of individuals with FEP, baseline psychosis, depression, and anxiety symptom severity differed by distinct multidimensional neighborhood profiles that were associated with where individuals reside. Exploring the cumulative effect of neighborhood factors improves our understanding of social, economic, and environmental impacts on symptoms and psychosis risk which could potentially impact treatment outcomes.

Changes to methadone maintenance therapy in the United States, Canada, and Australia during the COVID-19 pandemic: A narrative review.

INTRODUCTION: In response to the COVID-19 pandemic, countries across the world made adaptations to policies regulating the provision of methadone maintenance therapy (MMT) to facilitate social distancing for health care providers and people in treatment. Many countries issued guidance about increasing take-home methadone doses after the onset of the pandemic. METHODS: In this review, we compare the regulation of MMT prior to the pandemic in the United States, Canada, and Australia, analyze changes to treatment policy in the context of COVID-19, and review emerging data on treatment outcomes. RESULTS: The United States only permits the prescription and disbursement of methadone for MMT treatment at federally designated opioid treatment programs (OTPs). Conversely, Australia and Canada operate on a community pharmacy-based distribution model, where patients can access methadone doses either in participating pharmacies or in some methadone clinics. CONCLUSION: Given reports of similar treatment outcomes and increased patient satisfaction since the pandemic-related policy changes, some changes including increased receipt of take-home doses should be considered for incorporation into post-pandemic treatment policies and regulations.

Travel Burden to Cancer Screening and Treatment Facilities Among Washington Women: Data From an Integrated Healthcare Delivery System.

PURPOSE: To characterize distance traveled for breast cancer screening and to sites of service for breast cancer treatment, among rural and urban women served by a Washington State healthcare network. METHODS: Data for this study came from one of the largest not-for-profit integrated healthcare delivery systems in Washington State. Generalized linear mixed models with gamma log link function were used to examine the associations between travel distance and sociodemographic and contextual characteristics of patients. RESULTS: Median travel distance for breast cancer screening facilities, hematologist/oncologists, radiation oncologists, or surgeons was 11, 19, 23, or 11 miles, respectively. Travel distance to breast cancer screening or referral facilities was longer in non-core metropolitan ZIP codes compared to metropolitan ZIP codes. AI/AN and Hispanic women travelled longer distances to reach referral facilities compared to other racial and ethnic groups. CONCLUSION: Disparities exist in travel distance to breast cancer screening and treatment. Further research is needed to describe sociodemographic and system level characteristics that contribute to such disparities and to discover novel approaches to alleviate this burden.

Availability of timely methadone treatment in the United States and Canada during COVID-19: A census tract-level analysis.

OBJECTIVES: We sought to compare timely access to methadone treatment in the United States (US) and Canada during the COVID-19 pandemic. METHODS: We conducted a cross-sectional study of census tracts and aggregated dissemination areas (used for rural Canada) within 14 US and 3 Canadian jurisdictions in 2020. We excluded census tracts or areas with a population density of less than one person per square km. Data from a 2020 audit of timely medication access was used to determine clinics accepting new patients within 48 h. Unadjusted and adjusted linear regressions were performed to examine the relationship between area population density and sociodemographic covariates and three outcome variables: 1) driving distance to the nearest methadone clinic accepting new patients, 2) driving distance to the nearest methadone clinic accepting new patients for medication initiation within 48 h, and 3) the difference in the driving distance between the first and second outcome. RESULTS: We included 17,611 census tracts and areas with a population density greater than one person per square kilometer. After adjusting for area covariates, US jurisdictions were a median of 11.6 miles (p value <0.001) further from a methadone clinic accepting new patients and 25.1 miles (p value <0.001) further from a clinic accepting new patients within 48 h than Canadian jurisdictions. CONCLUSIONS: These results suggest that the more flexible Canadian regulatory approach to methadone treatment is associated with a greater availability of timely methadone treatment and reduced urban-rural disparity in availability, compared to the US.

Fulminant pulmonary tuberculosis in a previously healthy young woman from the Marshall Islands: Potential risk factors.

A 19-year-old woman originally from the Republic of the Marshall Islands presented with diffuse pneumonia and acute hypoxemic respiratory failure. She dies one month into her hospitalization but the diagnosis of pulmonary tuberculosis (TB) was not made until one day before her demise. A contact investigation screened a total of 155 persons with 36 (23%) found to have latent TB infection and seven (4.5%) with active pulmonary TB. This unfortunate case provided the opportunity to analyze the epidemiology of TB in the state of Washington in the context of those who emigrated from the Marshall Islands. The development of fulminant pulmonary TB in this previously healthy young woman also provides a segue to discuss potential risk factors for TB in the index case that include: (i) foreign-born in a TB-endemic country; (ii) race and genetic factors; (iii) age; (iv) body habitus; (v) pregnancy; and (vi) use of glucocorticoids.

COVID-19 and inequities in colorectal and cervical cancer screening and diagnosis in Washington State.

INTRODUCTION: Studies have shown that cancer screenings dropped dramatically following the onset of the coronavirus diseases 2019 (COVID-19) pandemic. In this study, we examined differences in rates of cervical and colorectal cancer (CRC) screening and diagnosis indicators before and during the first year of the COVID-19 pandemic. METHODOLOGY: We used retrospective data from a large healthcare system in Washington State. Targeted screening data included completed cancer screenings for both CRC (colonoscopy) and cervical cancer (Papanicolaou test (Pap test)). We analyzed and compared the rate of uptake of colorectal (colonoscopies) and cervical cancer (Pap) screenings done pre-COVID-19 (April 1, 2019-March 31, 2020) and during the pandemic (April 1, 2020-March 31, 2021). RESULTS: A total of 26,081 (12.7%) patients underwent colonoscopies in the pre-COVID-19 period, compared to only 15,708 (7.4%) patients during the pandemic, showing a 39.8% decrease. A total of 238 patients were referred to medical oncology for CRC compared to only 155 patients during the first year of the pandemic, a reduction of 34%. In the pre-COVID-19 period, 22,395 (10.7%) women were administered PAP tests compared to 20,455 (9.6%) women during the pandemic, for a 7.4% reduction. period 1780 women were referred to colposcopy, compared to only 1680 patients during the pandemic, for a 4.3% reduction. CONCLUSION: Interruption in screening and subsequent delay in diagnosis during the pandemic will likely lead to later-stage diagnoses for both CRC and cervical cancer, which is known to result in decreased survival. IMPACT: The results emphasize the need to prioritize cancer screening, particularly for those at higher risk.
