RESUMEN

The cognitive interview process is a method to validate a survey instrument's face validity and enhance confidence in item interpretation, as well as a method to engage communities in the research process. Trained American Indian and Alaska Native (AIAN) interviewers conducted retrospective cognitive interviews at three AIAN communities to assess the item quality of a 131-item survey item that measures AIAN knowledge and attitudes on genetics and biological specimens. A cognitive interview process was used to assess cultural consonance, thought processes used when considering survey instructions, items and responses, and language preference of survey items in the development of a survey to assess public knowledge and attitudes on genetics. Content analysis was used to analyze interview data. Survey instructions, items and scales generated no cognitive difficulties. The participants noted being unfamiliar with terminology used to describe genetic and biological specimens. In several cases, the participants' written response in the survey and verbal response in the interview did not align. A resultant 52-item survey for use in AIAN communities was finalized. Cognitive interviewing is resource-intensive; however, ignoring community engagement during survey development results in inappropriate interpretations about culturally diverse populations such as AIAN peoples.

RESUMEN

Background: The COVID-19 pandemic has substantially impacted American Indian and Alaska Native (AI/AN) communities. Rates of infection, hospitalization, and mortality have been severe relative to non-Hispanic whites. While AI/AN communities have had some of the highest levels of COVID-19 vaccination, utilization rates remain suboptimal and there is a need to identify facilitators and barriers to testing and vaccination. Methods: We examined cross-sectional survey data from January to May 2021, among 619 AI/AN patients from five tribal health organizations (AK, CO, KS, NM, WA). Exposures include perceived stress, Kessler distress, PTSD screening, and AUDIT-C alcohol misuse screen. Poisson regression was used to estimate associations with prevalence of COVID-19 testing and vaccination. Results: Over three-quarters of participants were tested for COVID-19 and nearly half were vaccinated. Perceived stress and positive PTSD screening were associated with reduced vaccination prevalence, Prevalence Ratio (PR) 0.83 (0.73, 0.93) and PR 0.80 (0.66, 0.98), respectively. There was reduced prevalence of COVID-19 testing in subgroups with lower reported psychological resilience and PTSD, PR 0.78 (0.64, 0.95). Conclusions: Past-month perceived stress and positive PTSD screening are associated with reduced prevalence of COVID-19 vaccination in urban AI/AN people. Subgroups reporting limited resilience and PTSD symptoms had lower prevalence of COVID-19 testing. The complex relationship between mental health and COVID-19 testing and vaccination warrants further exploration to identify interventions to improve health among urban AI/AN people, a population with known disparities in both mental health and COVID-19 outcomes.

RESUMEN

PURPOSE: To develop a culturally-tailored American Indian/Alaska Native (AI/AN) women's Facebook group supporting opioid recovery as an adjunct to medication. DESIGN: Community-based, qualitative approach. SETTING: Minnesota, U.S. PARTICIPANTS: AI/AN women in opioid recovery, interested parties, and a Community Advisory Committee (CAC) of AI/AN women with lived experience, health care providers, and community members. INTERVENTION: We developed evidence-based content focusing on stress/trauma and substance use, mindfulness, responding to triggers, and supportive community resources. Additional content centered on AI/AN culture was also selected. METHOD: Interviews were conducted by two women, then transcribed and coded using content analysis with NVivo software. Results were presented to CAC for further content refinement. RESULTS: CAC members (n = 10) guided study methods, intervention development, and dissemination activities. 14 AI/AN women (mean age 36.4 years; mean 6.7 months opioid abstinence) and 12 interested parties (7 men, 5 women) were receptive to an AI/AN gender-specific Facebook group, preferring content with AI/AN people and/or text resonating with AI/AN culture (e.g., Native traditions, family, personal stories, historical trauma). Recommendations included (1) protect confidentiality, (2) retain positivity, (3) incorporate resources and exercises to build coping skills, and (4) moderators should be authentic and relatable to build trust. CONCLUSIONS: Our approach provides a model for developing culturally tailored, appealing and effective social media interventions to support AI/AN women in recovery from opioid use disorder.

RESUMEN

OBJECTIVE: The COVID-19 pandemic has disproportionately affected American Indian and Alaska Native (AI/AN) people, who experience a 3.2 times higher age-adjusted rate of hospitalization and nearly double the attributed deaths compared to non-Hispanic Whites. We examined pandemic effects on emotional health and substance use in urban AI/AN people. METHODS: From January-May 2021 we collected cross-sectional data from 642 patients seen at five health organizations serving primarily AI/AN people in urban settings. The outcomes are self-reported, cross-sectional changes in emotional health and substance use since pandemic onset. Exposures of interest include infection history, COVID-19 risk perception, pandemic-related life disruption, and feared effects on AI/AN culture. Poisson regression was used to model adjusted multivariate associations. RESULTS: Since pandemic onset, 46% of participants reported worsened emotional health; 20% reported increased substance use. Very or extremely disruptive pandemic experiences and increasing reported feared pandemic effects on culture were associated with worse pandemic emotional health [adjusted Prevalence Ratio 1.84; 95% CI 1.44, 2.35 and 1.11; 95% CI 1.03, 1.19], respectively. COVID-19 infection and risk perception were not associated with emotional health after adjustment for other factors. The primary exposures were not associated with change in substance use. CONCLUSIONS: The COVID-19 pandemic has impacted the emotional health of urban AI/AN people. The finding that poor emotional health is associated with pandemic-related threats to AI/AN culture may signal a protective role for community and cultural resources. This warrants further study as exploratory analysis did not find hypothesized effect modification according to strength of affiliation with AI/AN culture.

RESUMEN

The population in rural southwest Alaska has been disproportionately affected by COVID-19. To assess the benefit of COVID-19 vaccines, we analyzed data from the regional health system. We estimated vaccine effectiveness (VE) during January 16-December 3, 2021, against symptomatic SARS-CoV-2 infection after a primary series or booster dose, and overall VE against hospitalization. VE of a primary series against symptomatic infection among adult residents was 91.3% (95% CI: 85.7, 95.2) during January 16-May 7, 2021, 50.3% (95% CI, 41.1%-58.8%) during July 17-September 24, and 37.0% (95% CI, 27.8-45.0) during September 25-December 3, 2021; VE of a booster dose during September 25-December 3, 2021, was 92.1% (95% CI: 87.2-95.2). During the overall study period, VE against hospitalization was 91.9% (95% CI: 85.4-95.5). COVID-19 vaccination offered strong protection against hospitalization and a booster dose restored protection against symptomatic infection.

RESUMEN

There are few substance use treatment and prevention programs for AI/AN people that integrate culturally based practices with evidence-based treatment and prevention. The National Institutes of Health's (NIH's) Helping to End Addiction Long-term (HEAL) Prevention Cooperative supports two projects focused on AI/AN populations. One focuses on youth ages 15 to 20 years living within the Cherokee Nation reservation, a multicultural rural area in northeastern Oklahoma, and the second focuses on emerging adults ages 18 to 25 years living in diverse urban areas. We provide a brief overview of the two prevention trials and a case comparison across approaches using the framework of promising practices for intervention science with Indigenous communities (Whitesell et al., 2020) related to (1) integration of Indigenous and academic perspectives to respond to community needs, (2) community partnership and engagement, (3) alignment with Indigenous cultural values and practices, (4) capacity building and empowerment, (5) implementation within complex cultural contexts, and (6) tribal oversight. Overall, these two projects highlight the importance of long-standing relationships with community partners, engaging the community at all levels to ensure that programming is culturally and developmentally appropriate, and having tribal and elder oversight. These practices are key to establishing trust and building confidence in research in these communities and ensuring that research can benefit AI/AN people. These studies showcase how strong partnerships can advance health and support the conduct of rigorous science to help pinpoint optimal health solutions by identifying efficacious, culturally grounded intervention strategies. Although the sovereign status of tribes demands this type of partnership, this research serves as a model for all community research that has a goal of improving health.

RESUMEN

Indigenous communities worldwide are at higher risk of negative pandemic outcomes, and communities Indigenous to the Arctic are disproportionately affected compared to national majorities. Despite this, their experiences have scarcely been investigated qualitatively and from their own perspectives. We collected and analyzed 22 structured interviews in three Southeast Alaska island communities (Sitka, Hoonah, and Kake) to learn about their perceptions of and experiences with the COVID-19 pandemic. Interviews were analyzed with thematic qualitative analysis in Dedoose. Four primary categories were identified within which to discuss risk and resilience in Southeast Alaska: (1) risk perception, (2) socioeconomic impacts, (3) reactions to public health guidelines, and (4) coping. Primary findings indicate that Southeast Alaska Native communities display considerable resilience and adaptive flexibility despite the significant adversity imposed by the COVID-19 pandemic. Southeast Alaska Native people use historical and traditional knowledge to culturally ground adaptive behaviors to cope with the threat of COVID-19. Interviewees expressed that adaptive, community-centered, and non-individualistic behaviors strongly tied to Native culture minimized the negative epidemiological impacts of the pandemic. Future research can more deeply explore the root causes of the need for adaptiveness and resilience, such as histories of colonialism and marginalization, to emergency situations in Indigenous communities.

RESUMEN

Social media platforms have potential for reach and effectiveness to motivate smoking cessation and use of evidence-based cessation treatment, even during the worldwide COVID-19 pandemic. This study builds on our prior community participatory approach to developing content postings for the CAN Quit Facebook intervention among Alaska Native (AN) people who smoke. With input from a community advisory committee, we selected new content on COVID-19 preventive practices (e.g., masking) and evaluated them using a validated, six-item perceived effectiveness scale and a single item assessing cultural relevance. We obtained feedback on six content postings (two videos and four text/pictures) from an online survey administered to 41 AN people (14 men, 27 women; age range 22-61 years) who smoke in Alaska statewide with 49 % residing in rural Alaska. Perceived effectiveness scale scores were high across postings, ranging from 3.9 to 4.4 out of a maximum score of 5.0. Cultural relevance item scores ranged from 3.9 to 4.3. We found no appreciable differences by sex, age, or rural/urban location for either score. This study adds new information on the adaptation, acceptability, and perceived effectiveness of content on COVID-19 preventive practices for future inclusion in a social media-based intervention for smoking cessation specifically tailored for AN people.

RESUMEN

Social, environmental, and behavioural factors impact human health. Integrating these social determinants of health (SDOH) into electronic health records (EHR) may improve individual and population health. But how these data are collectedand their use in clinical settings remain unclear. We reviewed efforts to integrate SDOH into EHR in the U.S. and Canada, especially how this implementation serves Indigenous peoples. We followed an established scoping review process, performing iterative keyword searches in subject-appropriate databases, reviewing identified works' bibliographies, and soliciting recommendations from subject-matter experts. We reviewed 20 articles from an initial set of 2,459. Most discussed multiple SDOH indicator standards, with the National Academy of Medicine's (NAM) the most frequently cited (n = 10). Common SDOH domains were demographics, economics, education, environment, housing, psychosocial factors, and health behaviours. Twelve articles discussed project acceptability and feasibility; eight mentioned stakeholder engagement (none specifically discussed engaging ethnic or social minorities); and six adapted SDOH measures to local cultures . Linking SDOH data to EHR as related to Indigenous communities warrants further exploration, especially how to best align cultural strengths and community expectations with clinical priorities. Integrating SDOH data into EHR appears feasible and acceptable may improve patient care, patient-provider relationships, and health outcomes.

RESUMEN

Gastric cancer is an aggressive and heterogeneous malignancy that often varies in presentation and disease among racial and ethnic groups. The Alaska Native (AN) people have the highest incidence and mortality rates of gastric cancer in North America. This study examines molecular markers in solid tumor samples from eighty-five AN gastric adenocarcinoma patients using next-generation sequencing, immunohistochemistry, and in situ hybridization analysis. AN patients have a low mutation burden with fewer somatic gene mutations in their tumors compared to other populations, with the most common mutation being TP53. Epstein-Barr virus (EBV) was associated with 20% of AN gastric cancers, which is higher than the world average of 10%. The inflammation marker, cyclooxygenase-2 (COX-2), is highly expressed in patients with the lowest survival rates. Mismatch repair deficiency was present in 10% of AN patients and was associated with patients who were female, 50 years or older, gene mutations, and tumors in the distal stomach. Program death-ligand 1 (PD-L1) was expressed in 14% of AN patients who were more likely to have MMR deficiency, EBV-associated gastric cancers, and mutations in the PIK3CA gene, all of which have been linked to clinical response to PD-1 inhibitors. These studies suggest a portion of AN gastric cancer patients could be candidates for immunotherapy. Overall, this study highlights future avenues of investigation for clinical and translational studies, so that we can improve early detection and develop more effective treatments for AN patients.

RESUMEN

BACKGROUND: Alaska Native (AN) people have the world's highest recorded incidence of sporadic colorectal cancer (CRC) (∼91:100,000), whereas rural African (RA) people have the lowest risk (<5:100,000). Previous data supported the hypothesis that diet affected CRC risk through its effects on the colonic microbiota that produce tumor-suppressive or -promoting metabolites. OBJECTIVES: We investigated whether differences in these metabolites may contribute to the high risk of CRC in AN people. METHODS: A cross-sectional observational study assessed dietary intake from 32 AN and 21 RA healthy middle-aged volunteers before screening colonoscopy. Analysis of fecal microbiota composition by 16S ribosomal RNA gene sequencing and fecal/urinary metabolites by 1H-NMR spectroscopy was complemented with targeted quantification of fecal SCFAs, bile acids, and functional microbial genes. RESULTS: Adenomatous polyps were detected in 16 of 32 AN participants, but not found in RA participants. The AN diet contained higher proportions of fat and animal protein and less fiber. AN fecal microbiota showed a compositional predominance of Blautia and Lachnoclostridium, higher microbial capacity for bile acid conversion, and low abundance of some species involved in saccharolytic fermentation (e.g., Prevotellaceae, Ruminococcaceae), but no significant lack of butyrogenic bacteria. Significantly lower concentrations of tumor-suppressive butyrate (22.5 ± 3.1 compared with 47.2 ± 7.3 SEM µmol/g) coincided with significantly higher concentrations of tumor-promoting deoxycholic acid (26.7 ± 4.2 compared with 11 ± 1.9 µmol/g) in AN fecal samples. AN participants had lower quantities of fecal/urinary metabolites than RA participants and metabolite profiles correlated with the abundance of distinct microbial genera in feces. The main microbial and metabolic CRC-associated markers were not significantly altered in AN participants with adenomatous polyps. CONCLUSIONS: The low-fiber, high-fat diet of AN people and exposure to carcinogens derived from diet or environment are associated with a tumor-promoting colonic milieu as reflected by the high rates of adenomatous polyps in AN participants.

RESUMEN

Precision medicine initiatives, such as Cancer Breakthrough 2020, promise to improve cancer outcomes by tailoring treatment to an individual's genes, environment, and lifestyle. This promise will fall short unless researchers successfully engage diverse communities, including those with histories of medical and research abuse. We examined a rural Alaska Native community's viewpoints about biospecimen collection and storage; interest and recall in reporting family health history; and interest and engagement in biospecimen collection for conducting a genetic test for cancer. In 2014, four focus groups were held with 28 adult Alaska Native rural community members. Thematic analysis was performed after establishing a coding scheme by team consensus. Study participants shared interest in engaging in genetic cancer research and suggested ways to improve community engagement in research. These included transparency and continuous communication with researchers at all stages of the research, clear communication about the intent of the research, and that research and results take into consideration the community's needs. These suggestions may be beneficial for future efforts to expand precision medicine research in Alaska Native communities and similar, diverse populations.

RESUMEN

BACKGROUND: Depression remains the second leading cause of disability worldwide. Symptoms of depression are expressed and experienced differently across cultural groups, impacting treatment decisions. Patient preferences predict service utilization, treatment selection and persistence, as well as health outcomes for medical and behavioral health conditions, including depression. We identified depression management preferences of Alaska Native and American Indian (AN/AI) people who receive care within a comprehensive, integrated, tribally owned and operated healthcare facility in Anchorage, Alaska. METHODS: Adult AN/AI patients who screened positive for depression (10 or greater on the Patient Health Questionnaire - 9 (PHQ-9)) completed a culturally-tailored decision-support tool to assess their depression management interests. RESULTS: The 125 eligible patients, who screened positive for depression, preferred counseling and medications to peer support groups, herbal remedies, and spiritual support. Those 18-39 years of age were more likely to prefer medications and less likely to prefer spirituality and peer support than those 40 years of age and older. Patients with moderate and severe depression were more likely to prefer exercise, healthy eating, and stress reduction than individuals with mild depression. LIMITATIONS: Women comprised 78% of the sample. Responses may not adequately represent the views of men. CONCLUSIONS: Counseling and medications should consistently be made available earlier in the course of depression management. Patient interest in exercise, stress reduction, and healthy eating to manage depression, especially among those with moderate and severe depression, offers opportunity for additional collaboration in an integrated care setting.

RESUMEN

BACKGROUND: The pneumococcal conjugate vaccine (PCV) was introduced in 2001. Widespread PCV use nearly eradicated pneumococcal colonization by vaccine serotypes. Since 2008, however, colonization by PCV-serotype 19F has increased in Alaska residents. We describe the epidemiology of re-emerging serotype 19F colonization. METHODS: We conducted annual cross-sectional colonization surveys from 2008 to 2013. We recruited children aged <5 years at 2 urban clinics and participants of all ages from Region-A (2 villages), Region-B (4 villages), and Region-C (2 villages). We interviewed participants and reviewed their medical records to obtain demographic information and determine PCV status. We obtained nasopharyngeal swab specimens from participants to identify pneumococci and to determine the pneumococcal serotype, antimicrobial resistance, and multilocus sequence type. We used the Cochran-Armitage test to assess for significant trends in colonization across time periods. RESULTS: Among participants aged <5 years, pneumococcal serotype 19F colonization remained unchanged from 2008-2009 (0.7%) to 2012-2013 (0.5%; P-value [P] = .54). Serotype 19F colonization increased from 2008-2009 to 2012-2013 among participants aged 5-11 years (0.3% to 3.2%; P < .01), participants 12-17 years (0.0% to 2.0%; P < .01), and participants aged ≥18 years (0.1% to 0.5%; P < .01). During 2012-2013, 85 (93%) of 91 pneumococcal serotype 19F isolates were identified among participants from Region B; the majority of serotype 19F isolates belonged to an antimicrobial nonsusceptibility pattern corresponding to a novel multilocus sequence type 9074. CONCLUSIONS: PCV continues to protect against serotype 19F colonization in vaccinated children aged <5 years. The direct PCV impact on serotype 19F colonization in persons aged 5-11 years and indirect impact in persons aged ≥12 years is waning, possibly because of a newly introduced genotype in Region-B.

RESUMEN

BACKGROUND & AIMS: Alaska Native people have an increased rate of hepatocellular carcinoma compared to the United States population. Viral hepatitis is a risk factor for malignancy and the leading cause of hepatocellular carcinoma in Alaska. With the introduction of hepatitis B immunization in 1982, as well as the emergence of hepatitis C virus in this population, the epidemiology and aetiology of hepatocellular carcinoma in Alaska have changed. METHODS: Using the Alaska Native Tumor Registry, all cases of viral and non-viral hepatocellular carcinoma occurring from 1969 through 2013 were identified and reviewed. Incidence rates per 100 000 population were calculated for hepatocellular carcinoma overall and by aetiological category. RESULTS: One hundred and fifty-two cases of hepatocellular carcinoma were identified in 148 Alaska Native persons. Overall tumour rate was 3.82 per 100 000 and did not change significantly over the study period. Hepatitis B-associated cases decreased significantly over the study period (P = 0.048) and were eliminated in persons under the age of 20. Hepatitis C-associated cases increased significantly (P < 0.001). Undetermined hepatocellular carcinoma rates also decreased (P = 0.034). CONCLUSIONS: Overall hepatocellular carcinoma rates in Alaska Native people remained stable over the study period, but the epidemiology and aetiology are changing. Two decades after routine hepatitis B immunization, the hepatocellular carcinoma age distribution has shifted to cases presenting later in life. This is consistent with an ageing hepatitis B-infected population with no new infected young persons' coming into the population, as well as the emergence of hepatitis C in adults.

RESUMEN

BACKGROUND: The American Association for the Study of Liver Diseases (AASLD) recommends semi-annual hepatocellular carcinoma (HCC) screening using ultrasound (US) in persons with chronic hepatitis B (CHB) virus infection at high risk for HCC such as Asian males aged ≥40 years and Asian females aged ≥50 years. OBJECTIVE: To analyse the cost-effectiveness of 2 HCC screening methods in the Alaska Native (AN) health system: US-alone, or screening by alpha-fetoprotein (AFP) initially and switching to US for subsequent screenings if AFP >10 ng/mL (AFP→US). DESIGN: A spreadsheet-based model was developed for accounting the costs of 2 hypothetical HCC screening methods. We used epidemiologic data from a cohort of 839 AN persons with CHB who were offered HCC screening by AFP/US semi-annually during 1983-2012. We assumed that compared with AFP→US, US-alone identifies 33% more tumours at an early stage (defined as a single tumour ≤5 cm or ≤3 tumours ≤3 cm in diameter). Years of life gained (YLG) attributed to screening was estimated by comparing additional years of survival among persons with early- compared with late-stage tumours. Screening costs were calculated using Medicare reimbursement rates in 2012. Future screening costs and YLG were projected over a 30-year time horizon using a 3% discount rate. RESULTS: The total cost of screening for the cohort by AFP→US would have been approximately $357,000 ($36,000/early-stage tumour detected) compared to $814,000 ($59,000/early-stage tumour detected) by US-alone. The AFP→US method would have yielded an additional 27.8 YLG ($13,000/YLG) compared with 38.9 YLG ($21,000/YLG) for US-alone. Screening by US-alone would incur an additional $114,000 per extra early-tumour detected compared with AFP→US and $41,000 per extra YLG. CONCLUSIONS: Although US-alone HCC screening might have yielded more YLG than AFP→US, the reduced costs of the AFP→US method could expand access to HCC screening in resource constrained settings.

RESUMEN

BACKGROUND: Community-acquired methicillin-resistant Staphylococcus aureus and methicillin-sensitive S. aureus infections are common to south-western Alaska and have been associated with traditional steambaths. More than a decade ago, recommendations were made to affected communities that included preventive skin care, cleaning methods for steambath surfaces, and the use of protective barriers while in steambaths to reduce the risk of S. aureus infection. OBJECTIVE: A review of community medical data suggested that the number of skin infection clinical encounters has increased steadily over the last 3 years and we designed a public health investigation to seek root causes. STUDY DESIGN: Using a mixed methods approach with in-person surveys, a convenience sample (n=492) from 3 rural communities assessed the range of knowledge, attitudes and practices concerning skin infections, skin infection education messaging, prevention activities and home self-care of skin infections. RESULTS: We described barriers to implementing previous recommendations and evaluated the acceptability of potential interventions. Prior public health messages appear to have been effective in reaching community members and appear to have been understood and accepted. We found no major misconceptions regarding what a boil was or how someone got one. Overall, respondents seemed concerned about boils as a health problem and reported that they were motivated to prevent boils. We identified current practices used to avoid skin infections, such as the disinfection of steambaths. We also identified barriers to engaging in protective behaviours, such as lack of access to laundry facilities. CONCLUSIONS: These findings can be used to help guide public health strategic planning and identify appropriate evidence-based interventions tailored to the specific needs of the region.

RESUMEN

This article presents the results of a process evaluation of the Alaska Native (AN) Colorectal Cancer (CRC) Family Outreach Program, which encourages CRC screening among AN first-degree relatives (i.e., parents, siblings, adult children; hereafter referred to as relatives) of CRC patients. Among AN people incidence and death rates from CRC are the highest of any ethnic/racial group in the United States. Relatives of CRC patients are at increased risk; however, CRC can be prevented and detected early through screening. The evaluation included key informant interviews (August to November 2012) with AN and non-AN stakeholders and program document review. Five key process evaluation components were identified: program formation, evolution, outreach responses, strengths, and barriers and challenges. Key themes included an incremental approach that led to a fully formed program and the need for dedicated, culturally competent patient navigation. Challenges included differing relatives' responses to screening outreach, health system data access and coordination, and the program impact of reliance on grant funding. This program evaluation indicated a need for more research into motivating patient screening behaviors, electronic medical records systems quality improvement projects, improved data-sharing protocols, and program sustainability planning to continue the dedicated efforts to promote screening in this increased risk population.

RESUMEN

BACKGROUND: This study examined predictors associated with readmission to detoxification in a sample of adult Alaska Native patients admitted to inpatient alcohol detoxification. Even though Alaska Native people diagnosed with alcoholism have been identified as frequent utilizers of the health care system and at elevated risk of death, little is known about factors associated with readmission to detoxification for this group. METHODS: We sought to predict readmission using a retrospective cohort study. The sample included 383 adult Alaska Native patients admitted to an inpatient detoxification unit and diagnosed with alcohol withdrawal during 2006 and 2007. Cox proportional hazard modeling was used to estimate unadjusted and adjusted associations with time to readmission within one year. RESULTS: Forty-two percent of the patients were readmitted within one year. Global Assessment Functioning (GAF; Axis V in the multi-axial diagnostic system of the Diagnostic and Statistical Manual of Mental Disorders [DSM IV]) score measured at the time of intake was associated with readmission. A one point increase in the GAF score (HR=.96, 95% CL=.94, .99, P=.002) was associated with a four percent decrease in readmission. The results also indicated that the GAF mediated the relationship between readmission and: employment and housing status. CONCLUSIONS: The GAF measures both illness severity and adaptive functioning, is part of standard behavioral health assessments, and is easy to score. Readmission rates potentially could be decreased by creating clinical protocols that account for differences in adaptive functioning and illness severity during detoxification treatment and aftercare.

RESUMEN

The gold standard for health information is the health record. Hospitalization and outpatient diagnoses provide health systems with data on which to project health costs and plan programmatic changes. Although health record information may be reliable and perceived as accurate, it may not include population-specific information and may exclude care provided outside a specific health care facility. Sole reliance on medical record information may lead to underutilization of health care services and inadequate assessment of population health status. In this study, we analyzed agreement, without assuming a gold standard, between self-reported and recorded chronic conditions in an American Indian/Alaska Native cohort. Self-reported health history was collected from 3821 adult participants of the Alaska EARTH study during 2004-2006. Participant medical records were electronically accessed and reviewed. Self-reported chronic conditions were underreported in relation to the medical record and both information sources reported the absence more reliably than the presence of conditions (across conditions, median positive predictive value = 64%, median negative predictive value = 94%). Agreement was affected by age, gender, and education. Differences between participant- and provider-based prevalence of chronic conditions demonstrate why health care administrators and policy makers should not rely exclusively on medical record-based administrative data for a comprehensive evaluation of population health.
