School-based health centers as an approach to address health disparities among rural youth: A study protocol for a multilevel research framework.

School-Based Health Centers (SBHCs) are important healthcare providers for children in medically underserved communities. While most existing research on SBHCs has focused on urban environments, this study protocol proposes a mixed-methods, multi-level research framework to evaluate the role of SBHCs in addressing health disparities among underserved children and adolescents in rural communities. The study area includes four high-poverty rural counties in New York State served by Bassett Healthcare Network that permits a comparison of school districts with SBHCs to those without SBHCs, all served by providers within the Bassett Healthcare Network. We employ a human ecological framework that integrates the micro layer of individuals and families, the meso layer of school districts and community institutions, and the macro layer of local and state policies. Our research framework first identifies the socioecological health risk factors, and then proposes innovative strategies to investigate how SBHCs impact them. We propose evaluating the impact of SBHCs on the individual (micro) level of child healthcare utilization using patient records data. At the meso level, we propose to investigate how School-SBHCs partnership may facilitate greater cross-agency collaboration and broader structural and social determinist of health to address health disparities. At the macro level, we propose to assess the impact of SBHCs and cross-agency collaboration on outcomes associated with a culture of community health. This study protocol will enable researchers to assess how SBHCs reduce rural health disparities, and provide evidence for organizational and public policy change.

Examining differences in time to appointment and no-show rates between rural telehealth users and non-users.

Background: Telehealth has undergone widespread implementation since 2020 and is considered an invaluable tool to improve access to healthcare, particularly in rural areas. However, telehealth's applicability may be limited for certain populations including those who live in rural, medically underserved communities. While broadband access is a recognized barrier, other important factors including age and education influence a person's ability or preference to engage with telehealth via video telehealth or a patient portal. It remains unclear the degree to which these digital technologies lead to disparities in access to care. Purpose: The purpose of this analysis is to determine if access to healthcare differs for telehealth users compared with non-users. Methods: Using electronic health record data, we evaluated differences in "time to appointment" and "no-show rates" between telehealth users and non-users within an integrated healthcare network between August 2021 and January 2022. We limited analysis to patient visits in endocrinology or outpatient behavioral health departments. We analyzed new patients and established patients separately. Results: Telehealth visits were associated with shorter time to appointment for new and established patients in endocrinology and established patients in behavioral health, as well as with lower no-show rates for established patients in both departments. Conclusions: The findings suggest that those who are unwilling or unable to engage with telehealth may have more difficulty accessing timely care.

The Effect of Mandatory Fitness Requirements on Cardiovascular Events: A State-by-State Analysis Using a National Database.

BACKGROUND: Cardiovascular events are known to be the leading cause of death among on-duty firefighters. Implementing fitness standards may help reduce the incidence of cardiovascular deaths; however, standards vary between firefighter type and states. We aimed to investigate the rate of cardiovascular events among firefighters across states. METHODS: Using publicly available data from the United States Fire Administration, we explored the rates of cardiovascular deaths between firefighter type (e.g., career, volunteer, and wildland) and state. Specifically, we examined rates of cardiovascular deaths between California and Tennessee, which have fitness standards for all firefighters, and New York, which does not have fitness standards for volunteer firefighters. We used descriptive statistics and trend analysis to examine the data. FINDINGS: Most cardiovascular events occur among volunteer firefighters (60.6%, n = 877). Volunteer firefighters had 7.5 (95% CI = [4.8, 11.7], p < .001) greater odds of cardiovascular events compared to wildland firefighters, who had the lowest incidence of cardiovascular events (1.7%, n = 24). New York reported the most cardiovascular events (n = 161), primarily among volunteer firefighters (73.9%, n = 119). After the passage of legislation mandating fitness standards in California, a downtrend in the number of volunteer firefighter fatalities is observed. However, a null effect was observed in Tennessee after the passage of similar fitness standards as in California. CONCLUSIONS/APPLICATIONS TO PRACTICE: Volunteer firefighters are significantly more likely to die of a cardiovascular event than career and wildland firefighters, both of which have stricter fitness standards. However, the effect of legislation mandating stricter fitness standards among volunteers did not produce a clear benefit for preventing fatalities. Nurses need to promote cardiovascular health among volunteer firefighters.

Rural Health Disparities in Allergy, Asthma, and Immunologic Diseases: The Current State and Future Direction for Clinical Care and Research.

Rural health disparities are well documented and continue to jeopardize the long-term health and wellness for the millions of individuals who live in rural America. The disparities observed between urban and rural residents encompass numerous morbidity and mortality measures for several chronic diseases and have been referred to as the "rural mortality penalty." Although the unmet health needs of rural communities are widely acknowledged, little is known about rural health disparities in allergies, asthma, and immunologic diseases. Furthermore, the intersection between rural health disparities and social determinants of health has not been fully explored. To achieve a more complete understanding of the factors that perpetuate rural health disparities, greater research efforts followed by improved practice and policy are needed that account for the complex social context within rural communities rather than a general comparison between urban and rural environments or focusing on biomedical factors. Moreover, research efforts must prioritize community inclusion throughout rural areas through meaningful engagement of stakeholders in both clinical care and research. In this review, we examine the scope of health disparities in the rural United States and the impact of social determinants of health. We then detail the current state of rural health disparities in the field of allergy, asthma, and immunology. To close, we offer future considerations to address knowledge gaps and unmet needs for both clinical care and research in addressing rural health disparities.

Exploring Multiple Dimensions of Access to and Preferences for Telehealth Use.

Introduction: During the pandemic, telehealth became critically important in care provision. Yet, research exposed the inequities facing various groups of people in terms of accessing telehealth. The purpose of this analysis was to examine the various dimensions of access that impact a person's ability to use and preference for telehealth. Methods: We used a mixed-methods approach framed by Levesque's Access to Health care model. In August, 2021, a stratified random sample of 500 patients of an integrated rural health care network was invited to participate in a survey designed to capture familiarity with, use of, and preference for digital technologies in general as well as with telehealth. In addition, key informant interviews were conducted between January 2022 and June 2022. Results: Patients' willingness to use telehealth was influenced by multiple dimensions of access, including approachability of the resource, acceptability, availability, affordability, and appropriateness. Clinician beliefs and attitudes as well as health care system policies affected how a patient perceived, sought, reached, and engaged with telehealth. Conclusions: Access is a dynamic, multifaceted concept that is influenced by individual-, organization-, and systemic-level factors. Looking beyond patient determinants and examining different dimensions of access is important to better facilitate implementation and sustainment of telehealth.

Trends in telehealth use among a cohort of rural patients during the COVID-19 pandemic.

Objective: Rural populations faced unique challenges to healthcare access during the COVID-19 pandemic. This analysis assesses trends in digital health technology use at the onset of the pandemic and describes digital health behaviors among a cohort of patients within a rural integrated healthcare network throughout the first 3 years of the pandemic. Methods: We used data from both the electronic health record (EHR) and a patient survey. EHR data was used to longitudinally assess change over time in patient portal use and telehealth visits. Survey responses were used to provide additional context. Results: Telehealth appointments peaked in the first quarter of 2020 at 28% of all office visits, before leveling off to 8-10% in 2022. Women and those younger than 65 were more likely to have participated in telehealth appointments. Active patient portal users increased from 34.1% in January 2019 to 63.7% in January 2022. There were no differences noted in portal use trends based on rurality. Conclusions: Our findings corroborate previous research, as well as add context regarding digital health technology use throughout the COVID pandemic in a rural patient population. Future research must focus on understanding constraints to digital health expansion in order to continue providing safe, equitable care.

Remote delivery of self-management education workshops for adults with chronic pain, 2020-2021.

OBJECTIVES: We intended to assess changes in pain-related outcomes among rural adults who completed 6-week self-management programs offered remotely during the COVID-19 pandemic. METHODS: We offered the Chronic Pain Self-Management Program and Chronic Disease Self-Management Program between May 2020 and December 2021. Delivery mode options included 2½-hour weekly videoconference, mailed toolkit plus 1-hour weekly conference call, and mailed toolkit alone. We conducted pre- and post-workshop surveys including questions on patient activation, self-efficacy, depression and pain disability. We used paired t-tests to compare pre-post differences in outcomes among participants completing 4 or more sessions. RESULTS: Among 218 adults reporting chronic pain, mean age was 57; 83.6% were female; and 49.5% participated via videoconference, 23.4% by phone and 27.1% via mailed toolkit alone. Completion rates were higher among phone (88.2%) versus videoconference (60.2%) workshop participants. Among completers, patient activation (mean change = 3.61, p = 0.01) and self-efficacy (mean change = 3.72, p < 0.0001) increased while depression scores (mean change = -1.03, p = 0.01), pain disability (mean change = -0.93, p = 0.003) and pain symptoms (mean change = -0.61, p = 0.001) decreased over the 6-week period. DISCUSSION: Self-management programs offered remotely during the pandemic were successful in improving patient activation, self-efficacy, depression, pain disability, and pain symptoms among rural adults experiencing chronic pain.

Determinants of Telehealth Technologies in a Rural Population.

Background: Telehealth's applicability may be limited for vulnerable populations including rural communities. While broadband access is a known barrier to telehealth use, other factors may influence a person's ability or preference to use telehealth. Objective/Purpose: To compare characteristics of telehealth users versus nontelehealth users in a rural health care network. Methods: We surveyed a stratified random sample of 500 adult patients in August 2021 about telehealth use. We used descriptive statistics to compare characteristics of telehealth users with nontelehealth users. Telehealth was defined in three different ways as follows: (1) phone or video visit, (2) video visit, and (3) patient portal use. Results: Mean age of the 206 respondents was 60 years, 60.7% were female, 60.4% had some college education; 84.9% had home internet, and 73.3% used the internet independently. Video telehealth use was independently associated with younger age (<65), having some college education, being married/partnered, and being enrolled in Medicaid. When telehealth included a phone option, disability was positively associated with telehealth use, and living in a rural town versus metropolitan/micropolitan area was negatively associated with telehealth use. Being younger, married/partnered, and having some college education were significantly associated with patient portal use. Conclusion: Videoconferencing and patient portal use pose barriers to those who are older and have less education. However, these barriers disappear when telehealth is available through telephone.

Prescribing Patterns for Long-Acting Inhaled Bronchodilators Among Rural Adults With Chronic Obstructive Pulmonary Disease.

Background: Chronic obstructive pulmonary disease (COPD) is prevalent in rural areas of the USA. Long-acting inhaled bronchodilators (LABDs) are a key tool in COPD management and are underutilized. The purpose of this study was to determine whether rates of prescriptions for LABD differed by payer among patients with COPD in a rural healthcare network. Methods: In analysis 1, a random sample of patients with spirometry- and symptom-confirmed COPD over April 1, 2017 to December 31, 2019 was identified. Patient characteristics, including payer status, extracted from medical records were compared for those who did and did not have any prescriptions for LABD during the study window. In analysis 2, patients with one or more COPD-related hospitalizations during the same time period were identified and similar comparisons were made by LABD prescription status. Results: Among a random sample of patients with spirometry-confirmed COPD, 93.0% had been prescribed LABD during the study window with no difference in proportion by payer. Among the 461 patients with a COPD-related hospitalization, 388 (84.2%) had been prescribed LABD, again with no difference in prescriptions by payer. Those with a COPD-related hospitalization who had been prescribed LABD were younger, had lower body mass index, were more likely to be current smokers and had higher rates of hospitalizations for COPD during the study period than those not prescribed LABD. Conclusion: While disparities in LABD utilization may occur due to cost or other barriers to filling prescriptions, in our study, prescriptions for LABD were common and did not differ by payer status.

Evaluation of a Peer Led Chronic Pain Self-Management Program in a Rural Population.

BACKGROUND: The Chronic Pain Self-Management Program is an evidence-based intervention that has been shown to be efficacious in reducing symptoms of chronic pain. However, there is a paucity of research examining CPSMP in a predominantly rural population. The purpose was to evaluate patient-reported outcomes of in-person peer-led CPSMP workshops offered in a rural region in 2018 and 2019. METHODS: Participants were surveyed at baseline and 6 months post-workshop. Descriptive statistics were used to describe characteristics of CPSMP completers. Paired t-tests were used to analyze change in depression score (PHQ-8), disability (modified Roland-Morris Disability Questionnaire), self-efficacy, and patient activation (PAM-10). Analysis of variance was used to detect differences over time by age group, education, insurance type, self-rated health, and comorbidities. RESULTS: Among the 327 adults who enrolled in a workshop, 73.1% completed. Of completers, 74.9% were female, average age was 65. Significant improvements were observed in pain disability (P = .0008), patient activation (P = .0362), depression (P < .0001), and self-efficacy (P < .0001), at 6 weeks; and pain disability (P = .0030), depression (P = .0015), and self-efficacy (P = .0064) at 6 months post-program. Individuals who rated their health as fair/poor at baseline reported greater improvements in depression scores than individuals who rated their health as good or better (P < .0002). There were also distinct patterns of change in pain disability among the different age groups. No other differences between groups were noted. CONCLUSIONS: The CPSMP appears to improve pain self-efficacy, disability, and depression regardless of age, gender, insurance status, education, or comorbidities. Healthcare and community organizations should consider investing in and offering chronic pain workshops in rural areas in order to promote health and wellness.

Comparison of antibody response durability of mRNA-1273, BNT162b2, and Ad26.COV2.S SARS-CoV-2 vaccines in healthcare workers.

OBJECTIVES: There are limited comparative immunologic durability data post COVID-19 vaccinations. METHODS: Approximately 8.4 months after primary COVID-19 vaccination, 647 healthcare workers completed surveys about COVID-19 vaccinations/infections and blood draws. The groups included participants vaccinated with mRNA-1273 (n = 387), BNT162b2 (n = 212), or Ad26.COV2.S (n = 10) vaccines; unvaccinated participants (n = 10); and participants who received a booster dose (n = 28). The primary outcome was immunoglobin anti-spike titer. Secondary/tertiary outcomes included neutralizing antibodies (enzyme-linked immunosorbent assay-based pseudoneutralization) and vaccine effectiveness (VE). Antibody levels were compared using analysis of variance and linear regression. RESULTS: Mean age was 49.7 and 75.3% of the participants were female. Baseline variables were balanced except for immunosuppression, previous COVID-19 infection, and post-primary vaccination time. Unadjusted median (interquartile range [IQR]) anti-spike titers (AU/ml) were 1539.5 (876.7-2626.7) for mRNA-1273, 751.2 (422.0-1381.5) for BNT162b2, 451.6 (103.0-2396.7) for Ad26.COV2.S, 113.4 (3.7-194.0) for unvaccinated participants, and 31898.8 (21347.1-45820.1) for participants administered with booster dose (mRNA-1273 vs BNT162b2, P <.001; mRNA-1273, BNT162b2, or boosted vs unvaccinated, P <.006; mRNA-1273, BNT162b2, Ad26.COV2.S, or unvaccinated vs boosted, P <.001). Unadjusted median (IQR) pseudoneutralization was as follows: 90.9% (80.1-95.0) for mRNA-1273, 77.2% (59.1-89.9) for BNT162b2, 57.9% (36.6-95.8) for Ad26.COV2.S, 40.1% (21.7-60.6) for unvaccinated, and 96.4% (96.1-96.6) for participants administered with booster dose (mRNA-1273 vs BNT162b2, P <.001; mRNA-1273, BNT162b2, or boosted vs unvaccinated, P <.028; mRNA-1273, BNT162b2, Ad26.COV2.S, or unvaccinated vs boosted, P <.001). VE was 87-89% for participants administered mRNA-1273 vaccine, BNT162b2 vaccine, and booster dose, and 33% for Ad26.COV2.S (none significantly different). CONCLUSION: Antibody responses 8.4 months after primary vaccination were significantly higher with mRNA-1273 than those observed with BNT162b2.

Loneliness Among Rural Self-Management Education Program Enrollees During the COVID-19 Pandemic.

PURPOSE: Pandemic-related isolation may exacerbate loneliness among rural adults; we sought to characterize loneliness and associated factors among rural adults during the COVID-19 pandemic. DESIGN: Cross-sectional observational study. SETTING: Remotely delivered self-management education (SME) workshops, rural upstate New York, May-December 2020. SUBJECTS: Rural SME workshop enrollees, aged 18+, n = 229. MEASURES: De Jong Gierveld 6-Item Loneliness Scale, sociodemographics, workshop type (chronic disease, chronic pain, diabetes), delivery mode (videoconference, phone, self-study); data collected via workshop process measures and enrollment surveys. ANALYSIS: Multivariable linear regression. RESULTS: Mean overall, emotional and social loneliness scores were 2.78 (SD = 1.91), 1.27 (SD = 1.02), and 1.52 (SD = 1.26). Being not married/partnered (ß = .61) and self-reported depression/anxiety (ß = .64) were associated with higher overall scores, and selection of videoconference (ß = -.77) and self-study (ß =-.85) modes with lower scores. Self-reported depression/anxiety (ß = .51) was associated with increased emotional loneliness. Being not married/not partnered (ß = .37) and selection of chronic pain workshops (ß = .64) was were associated with increased social loneliness. Selection of videoconference (ß = -.44) and self-study (ß = -.51) delivery modes were protective of social loneliness. CONCLUSION: In addition to marital status and depression/anxiety, experiencing chronic pain and selecting phone-based workshops were associated with higher degrees of loneliness among rural adults during the pandemic. The latter may be partly explained by insufficient internet access. Health educators should be prepared to address loneliness in rural areas during the pandemic.

Recruitment and engagement in disease self-management programs: Special concerns for rural residents reporting depression and/or anxiety.

Chronic disease self-management education (CDSME) programs benefit individuals with chronic diseases, including mental health conditions, by improving health-related outcomes and increasing engagement with the health care system. Recruiting individuals with a history of mental health conditions to participate in CDSME is challenging, particularly in rural, underserved areas. Hence, it is important to understand factors associated with the presence of mental health conditions, and impacts of CDSME on patient engagement. This project identifies individual and program-level characteristics, as well as recruitment characteristics, associated with reporting a history of depression and/or anxiety. It also assesses factors related to program engagement and the relationship between completing CDSME and patient activation. Data were collected during CDSME workshops offered in 2019 in a rural region of New York. Of the 421 enrollees who completed survey instruments, 162 reported a history of depression and/or anxiety. Univariate analyses indicated that those reporting a history of depression and/or anxiety were younger, female, in poorer health, had more comorbidities, were Medicaid beneficiaries, and had lower patient activation scores. They also heard about and signed up for the workshop through the internet at higher rates than those not reporting a history of depression and/or anxiety. Multivariable logistic regression modeling indicated age, self-rated health, and number of comorbidities were independent predictors of reporting a history of depression and/or anxiety. Among CDSME completers, patient activation significantly improved regardless of history of depression and/or anxiety. Engaging individuals with mental health conditions in CDSME requires a multimodal recruitment strategy incorporating electronic marketing and registration.

Implementation of Evidence-Based Disease Self-Management Programs in a Rural Region: Leveraging and Linking Community and Health Care System Assets.

CONTEXT: Rural populations experience both a higher prevalence of and risk for premature death from chronic conditions than do their urban counterparts. Yet barriers to implement community-based chronic disease self-management programs persist. PROGRAM: The Living Well program, a multi-sector collaboration between a rural health care system and a network of community-based organizations, has offered the 6-week evidence-based Chronic Disease Self-Management and Diabetes Self-Management workshops since 2017. The program was a response to a quality improvement initiative to improve hypertension and diabetes outcomes throughout the health care system. IMPLEMENTATION: Using the rapid cycling quality improvement process, Living Well developed a self-management program recruitment, referral, and coordinating office for a six-county region. Through continuous capacity-building efforts with community partners, as well as leveraging key health care system assets such as the electronic health record and provider detailing, program reach and adoption was increased. EVALUATION: The Reach, Effectiveness, Adoption, Implementation, and Maintenance framework was used for the process evaluation. During 3 years, more than 750 individuals engaged with the program, with nearly 600 completing a workshop. The region saw increased engagement by primary care clinicians to refer, and structural changes were embedded into the health care system to facilitate clinic-community partnerships. DISCUSSION: A coordinated, multi-sector approach is necessary to develop solutions to complex, chronic health problems. A regional coordinating hub is an effective strategy for implementing community-based programs in rural areas. However, low health care system engagement and fragmented funding remain as barriers to optimal implementation.

Associations between depressive symptoms, cigarette smoking, and cardiovascular health: Longitudinal results from CARDIA.

INTRODUCTION: Depression is associated with increased risk of incident and recurrent cardiovascular disease, while the association between depression and cardiovascular health (CVH) remains unknown. Because the natural course of depression varies widely, different patterns of depression, as well as co-occurring factors such as cigarette smoking, may influence this relationship. We examined potential interactions between longitudinal patterns of depression and smoking with CVH. METHODS: Using data from the Coronary Artery Risk Development in Young Adults (CARDIA) study, we modeled trajectories of depression (Center for Epidemiologic Studies Depression scale scores; Years 5, 10, 15, 20) and smoking (cigarettes/day; Years 0, 2, 5, 7, 10, 15, 20). We calculated a modified American Heart Association (AHA) CVH Score (weight, blood glucose, cholesterol, blood pressure, physical activity, and diet; Year 20); higher scores indicate better CVH. Generalized linear models evaluated associations between depression trajectories, smoking trajectories, and their interaction with CVH Score. RESULTS: The depression trajectory x smoking trajectory interaction was not associated with CVH Score, but main effects of depression trajectory (p < .001) and smoking trajectory (p < .001) were observed. Participants with patterns of subthreshold depression (ß = -0.26, SE=0.08), increasing depression (ß = -0.51 SE = 0.14), and high depression (ß = -0.65, SE = 0.32) had lower CVH Scores than those without depression. Compared to never smokers, participants who quit smoking had higher CVH Scores (ß = 0.38, SE = 0.11), while participants with the greatest smoking exposure had lower CVH Scores (ß = -0.49, SE = 0.22). LIMITATIONS: CVH Scores were adapted from the AHA guidelines based on the available CARDIA data. CONCLUSIONS: Deleterious depression and smoking trajectories are independently but not synergistically associated with worse CVH.

Depression and risk of incident asthma in adults. The CARDIA study.

RATIONALE: Asthma is associated with depression, but the temporality of the association has not been established. OBJECTIVES: To examine the association between prevalent elevated depressive symptoms and incident asthma, and between prevalent asthma and incident elevated depressive symptoms in a cohort of young and middle-aged adults. METHODS: We examined the longitudinal association between asthma and depressive symptoms bidirectionally in the Coronary Artery Risk Development in Young Adults (CARDIA) cohort. First, 3,614 participants, free of asthma, were classified by elevated depressive symptoms at the CARDIA Year-5 exam (n = 856 elevated vs. 2,758 not elevated; ages 23-35 yr) and followed for 20 years to incident asthma. Then, 3,016 participants, free of elevated depressive symptoms, were classified by self-reported current asthma status (n = 188 prevalent vs. 2,828 not prevalent) at the CARDIA Year-5 exam and followed for 20 years until onset of elevated depressive symptoms. MEASUREMENTS AND MAIN RESULTS: The relative hazard of incident asthma among those with elevated depressive symptoms was 1.26 (95% confidence interval [CI] = 1.02-1.56) after adjustment for covariates. When depressive status was modeled as the total number of reports of elevated depressive symptoms before the onset of asthma, the adjusted hazard ratio was 1.15 (95% CI = 1.02-1.29). The hazard of incident elevated depressive symptoms for those with asthma was no different than the hazard in those without asthma (adjusted hazard ratio = 0.92; 95% CI = 0.70-1.20). CONCLUSIONS: This longitudinal observational study points to depression as a marker of risk for incident adult-onset asthma. On the other hand, prevalent asthma is not associated with incident adult-onset depression.

Prevalence of work-related asthma in Michigan, Minnesota, and Oregon.

INTRODUCTION: Adults who have asthma that is caused or aggravated by triggers at work experience a reduced quality of life. In this study, the authors sought to estimate the proportion of asthma that is associated with work using a state-based survey of adults with asthma. METHODS: In 2005, Michigan, Minnesota, and Oregon piloted the Behavioral Risk Factor Surveillance System Adult Asthma Call-Back Survey, with sample sizes of 867, 469, and 1072, respectively. Six questions addressing work-related asthma (WRA) were analyzed to generate estimates of the proportion of adult asthma that is work-related and compare those with and without WRA. RESULTS: Over half of all adults with asthma (53%) reported that their asthma was caused or made worse by any job they ever had, and among these respondents reporting WRA, only 21.5% to 25.1% reported ever telling or being told by a health professional that their asthma was work-related. Additionally, adults with WRA consistently reported poorer asthma control and higher health care utilization than adults with non-WRA. CONCLUSIONS: WRA is a common but frequently unrecognized health problem, and this lack of recognition might contribute to poorer asthma control among adults with WRA. Because early recognition, treatment, and management of WRA are crucial for improving long-term prognosis, clinicians need to include assessment of workplace triggers in both their diagnostic and treatment plans for adult patients with asthma.

Review of the asthma mortality rate for Minnesota residents aged 55 years or older, 2004-2005: when death certificates deserve a second look.

INTRODUCTION: Asthma mortality rates are based on deaths for which asthma is coded as the underlying cause on the death certificate. We conducted an asthma mortality review to evaluate this surveillance measure for Minnesota residents who were aged 55 years or older METHODS: We enlisted an expert panel to review transcribed interviews from the next-of-kin and case histories for decedents whose deaths were attributed to asthma. In addition, we examined death certificates to determine whether the certifier had intended asthma to be the underlying cause. RESULTS: In the age group of Minnesotans we examined, 55 deaths were attributed to asthma during the 1-year study period. Of the 35 deaths for which adequate information was available for review, 2 were determined to be due to asthma. On 33 of the 55 death certificates, the certifier had chosen asthma as the underlying cause; on the rest, the certifier had not chosen asthma, but inconsistencies in death certificate completion had resulted in "asthma" automatically overriding the underlying cause that had been chosen. CONCLUSION: Asthma mortality rates for older Minnesotans may be overestimated because of inaccurate reporting of the underlying cause of death on death certificates.

Investigation of exposures to commercial asbestos in northeastern Minnesota iron miners who developed mesothelioma.

A 70% excess of mesothelioma, an asbestos-related cancer, has been reported among men in northeastern Minnesota, where iron mining has been the major industry. The Minnesota Department of Health has studied iron miners who developed mesothelioma to identify possible sources of asbestos exposure. A database of all Minnesota residents diagnosed with mesothelioma between 1988 and 1996 was linked to a database of approximately 72,000 current and former Minnesota iron-mining employees to identify cases who had ever worked in the mining industry. The job histories of the cases were examined to determine if any of their jobs could have involved exposure to commercial asbestos. Seventeen individuals diagnosed with mesothelioma in Minnesota between 1988 and 1996 were found to have worked in the iron mining industry. Of the 15 for whom adequate work histories were available, 14 had identifiable sources of exposure to commercial asbestos in jobs held both inside and outside of the mining industry. The time between employment in these asbestos-exposed occupations and the diagnosis of mesothelioma is consistent with the 20 or more year latency period that has been observed in other studies of this cancer.
