Culturally tailoring a secondary suicide prevention intervention for American Indian and Alaska Native people in substance use treatment.

BACKGROUND: Substance use treatment programs are ideal places for suicide prevention interventions. People who misuse substances are at elevated risk for suicide compared to the general population. However, most treatment programs do not incorporate suicide prevention, and none have been adapted for American Indian and Alaska Native (AI/AN) people. Preventing Addiction Related Suicide (PARS) is a suicide prevention module developed for use with people in treatment for substance misuse. A previous study demonstrated increased suicide help-seeking among this population. OBJECTIVE: Culturally adapt PARS for use with AI/AN communities. METHODS: We conducted focus groups and interviews with stakeholders in three Tribal health systems. We elicited feedback on PARS content, structure, and implementation. Data were analyzed using constant comparison. Results were used to adapt PARS and member checking was used to refine it. RESULTS: Participants unanimously endorsed using PARS in their health systems. Suggested adaptations included shortening the module, using community-specific information, removing jargon and stigmatizing language, and emphasizing cultural connectedness. DISCUSSION: This community-based, qualitative study adapted the PARS module for use with AI/AN communities. Research is needed to evaluate the clinical effectiveness of the adapted module. If found effective, this would represent the first evidence-based suicide prevention intervention among AI/AN individuals in treatment for substance misuse.

Suicide-related care among patients who have experienced an opioid-involved overdose.

OBJECTIVE: Our objective was to describe suicide prevention care for individuals prescribed opioids or with opioid use disorder (OUD) and identify opportunities for improving this care. METHODS: Adult patients (n = 65) from four health systems with an opioid-involved overdose and clinicians (n = 21) who had contact with similar patients completed 30-60-min semi-structured interviews. A community advisory board contributed to development of all procedures, and interpretation and summary of findings. RESULTS: Patients were mostly female (59%), White (63%) and non-Hispanic (77%); 52 were prescribed opioids, 49% had diagnosed OUD, and 42% experienced an intentional opioid-involved overdose. Findings included: 1) when prescribed an opioid or treated for OUD, suicide risks were typically not discussed; 2) 35% of those with an intentional opioid-involved overdose and over 80% with an unintentional overdose reported no discussion of suicidal ideation when treated for the overdose; and 3) suicide-related follow-up care was uncommon among those with unintentional overdoses despite suicidal ideation being reported by >20%. Clinicians reported that when prescribing opioids or treating OUD, post-overdose suicide-related screening or counseling was not done routinely. CONCLUSIONS: There were several opportunities to tailor suicide prevention care for patients who were treated for opioid-involved overdoses within health systems.

Recovery from alcohol among urban Alaska Native and American Indian people.

Alaska Native and American Indian (ANAI) people experience dramatic alcohol-related health disparities compared to the general US population. Although the majority of ANAI people reside in urban settings (>70%), data are sparse on alcohol abstinence among urban ANAI people with alcohol use disorder (AUD). We conducted a qualitative study using a phenomenological approach to examine the experiences of 20 urban ANAI adults recovering from AUD. Participants' narratives had their own unique dimensions but shared a clear, interrelated trajectory of pre-alcohol recovery, a turning point, and ongoing alcohol recovery. All participants reported a combination of external and internal motivation to stop using alcohol.

Culturally Adapting Caring Contacts for Suicide Prevention in Four Alaska Native and American Indian Communities.

AIM: Despite substantial tribal, state, and federal effort, American Indian and Alaska Native (AI/AN) suicide rates have changed little in the last 30 years, prompting attention to new and innovative approaches to this persistent health disparity. Suicide prevention interventions with demonstrated success in other populations may be useful in AI/AN communities. Caring Contacts is a suicide prevention intervention that has been adapted and shown to reduce suicide ideation, attempts, and deaths in other populations. CONCLUSION: Overall, AI/AN study participants in four diverse AI/AN communities endorsed the use of Caring Contacts for suicide prevention in their communities. Intervention adaptations for use in these communities centered primarily on message frequency and timing as well as expanding access to Caring Contacts. The results of this study may be applicable to other populations that experience suicide-related health disparities. METHODS: We used a community-based participatory research approach to gather qualitative data from community members, healthcare providers, and leaders in four AI/AN communities. These data were analyzed thematically and used to adapt Caring Contacts for use in a subsequent clinical trial with AI/AN people at high risk for suicide. RESULTS: A total of 189 community members and other health system stakeholders in four tribal communities participated in focus groups and interviews. Caring Contacts was perceived in all communities to be acceptable. Feedback for intervention adaptations focused on the themes of trial eligibility criteria; instruments; message frequency, timing, and content; and cultural considerations.

Measuring Attitudes About Alcohol Misuse and Dependence Among Alaska Native People Within a Tribal Health Care System.

OBJECTIVES: Attitudes about alcohol misuse and dependence influence alcohol use and help-seeking behavior. Alaska Native and American Indian (AN/AI) people have higher rates of alcohol-related morbidity and mortality but engage in treatment at lower rates than the general population. No validated instruments exist to assess attitudes of AN/AI people about alcohol misuse and dependence to inform treatment and prevention efforts. This study aimed to develop an instrument to assess public attitudes among AN/AI people of alcohol misuse and dependence. METHODS: This multiphase, mixed-methods study was conducted at Southcentral Foundation, a tribally owned health system serving 65,000 AN/AI people in Alaska. We conducted focus groups and interviews with health system users, providers, and leaders to adapt the Public Attitudes About Addiction Survey. The adapted instrument was piloted with 200 people. Cognitive interviews and exploratory and confirmatory factor analyses were used to refine the instrument, which were then administered to 777 AN/AI people. RESULTS: Initial exploratory factor analysis identified 5 factors, including 3 from the original Public Attitudes About Addiction Survey (moral, disease, nature), a combined psychology and sociology factor (psychosocial), and a new factor (environment). A final 4-factor model (psychosocial, moral, disease, nature) with 14 items had good fit with root mean square error of approximation (0.035; comparative fit index = 0.977; Tucker-Lewis index = 0.970; standardized root mean residual = 0.040) and loadings ranging from 0.41 to 0.80. CONCLUSIONS: This study developed the first instrument to assess AN/AI attitudes about alcohol misuse and dependence. This instrument has potential to inform alcohol-related treatment in AN/AI communities. Future research is warranted to adequately measure place-based contributors salient to AN/AI people.

Validating a predictive algorithm for suicide risk with Alaska Native populations.

INTRODUCTION: The American Indian/Alaska Native (AI/AN) suicide rate in Alaska is twice the state rate and four times the U.S. rate. Healthcare systems need innovative methods of suicide risk detection. The Mental Health Research Network (MHRN) developed suicide risk prediction algorithms in a general U.S. METHODS: We applied MHRN predictors and regression coefficients to electronic health records of AI/AN patients aged ≥13 years with behavioral health diagnoses and primary care visits between October 1, 2016, and March 30, 2018. Logistic regression assessed model accuracy for predicting and stratifying risk for suicide attempt within 90 days after a visit. We compared expected to observed risk and assessed model performance characteristics. RESULTS: 10,864 patients made 47,413 primary care visits. Suicide attempt occurred after 589 (1.2%) visits. Visits in the top 5% of predicted risk accounted for 40% of actual attempts. Among visits in the top 0.5% of predicted risk, 25.1% were followed by suicide attempt. The best fitting model had an AUC of 0.826 (95% CI: 0.809-0.843). CONCLUSIONS: The MHRN model accurately predicted suicide attempts among AI/AN patients. Future work should develop clinical and operational guidance for effective implementation of the model with this population.

Using the electronic health record to identify suicide risk factors in an Alaska Native Health System.

Suicide rates are higher in some Alaska Native and American Indian communities than the general U.S. population. Screening for suicide risk typically requires self-report, but many people may not engage with conventional screening because of distrust or are reluctant to disclose thoughts of suicide. Resource-sensitive methods of detecting suicide risk are needed. This study identifies routinely collected electronic health record data to identify demographic, clinical, and utilization factors associated with suicide-related visits in a tribal health care system. In this retrospective, case-control study, cases were defined as any person with a suicide-related visit from 2012 to 2015. Cases and controls were matched by age, sex, and urban/rural residence. We used conditional logistic regression to estimate odds ratios, which were interpreted as prevalence ratios (PR) based on the rare outcome assumption. The dataset included 314 cases and 1,169 controls. In the year before the index visit, cases had higher prevalence of poisoning or overdose (PR = 13.4, 95% confidence interval [CI] [3.5, 51.7]), emergency department and urgent care visits (PR = 15.8, 95% CI [6.6, 38.1]), and hospitalizations (PR = 4.5, 95% CI [3.0, 6.8]). Electronic health records can be used to identify factors that are significantly associated with suicide risk among those who may not be flagged by screening. Risk detection through electronic health record assessment might increase clinical workload in the short term, but this change would be offset by downstream prevention of suicide-related events. Such efforts could improve suicide risk detection and help to improve suicide-related health disparities in Alaska Native and American Indian populations.

Contingency management for alcohol use disorder reduces cannabis use among American Indian and Alaska Native adults.

OBJECTIVE: Determine whether a culturally tailored contingency management (CM) intervention targeting alcohol abstinence resulted in secondary effects on cannabis use among American Indian and Alaska Native (AI/AN) adults. METHODS: The research team conducted this secondary data analysis to examine cannabis abstinence using data from a randomized control trial of CM for alcohol use among three AI/AN-serving organizations. One hundred and fifty-eight adults met the randomization criteria (i.e., submission of 50% or more urine samples and one alcohol-positive urine test during a 4-week, pre-randomization, observation period). For 12 weeks after randomization, participants received incentives for submitting a urine test negative for ethyl glucuronide (EtG < 150 ng/mL, CM group) or incentives for submitting a urine sample regardless of abstinence (Non-contingent [NC] Control group). Generalized linear mixed effects models assessed group differences in cannabis abstinence during the intervention, verified by urine tetrahydrocannabinol negative tests (11-nor-delta-9-tetrahydrocannabinol-9-carboxylic acid <50 ng/mL). RESULTS: At baseline, 42.2% (n = 35) of participants in the NC group and 40.0% (n = 30) of those in the CM group had a cannabis positive urine test. An overall intervention by time interaction was detected for a cannabis negative urine test (χ2 = 13.40, p = 0.001). Compared to the NC group, the CM group had 3.92 (95% CI:1.23-12.46) times higher odds of having a cannabis negative urine test during the intervention period and 5.13 (95% CI:1.57-16.76) times higher odds of having a negative cannabis test at the end of intervention period. CONCLUSION: CM addressing alcohol misuse may be an effective strategy for decreasing cannabis use among AI/AN adults. TRIAL REGISTRATION: ClinicalTrials.gov number, Identifier: NCT02174315.

Best Practices for Conducting Clinical Trials With Indigenous Children in the United States.

We provide guidance for conducting clinical trials with Indigenous children in the United States. We drew on extant literature and our experience to describe 3 best practices for the ethical and effective conduct of clinical trials with Indigenous children. Case examples of pediatric research conducted with American Indian, Alaska Native, and Native Hawaiian communities are provided to illustrate these practices. Ethical and effective clinical trials with Indigenous children require early and sustained community engagement, building capacity for Indigenous research, and supporting community oversight and ownership of research. Effective engagement requires equity, trust, shared interests, and mutual benefit among partners over time. Capacity building should prioritize developing Indigenous researchers. Supporting community oversight and ownership of research means that investigators should plan for data-sharing agreements, return or destruction of data, and multiple regulatory approvals. Indigenous children must be included in clinical trials to reduce health disparities and improve health outcomes in these pediatric populations. Establishment of the Environmental Influences on Child Health Outcomes Institutional Development Award States Pediatric Clinical Trials Network (ECHO ISPCTN) in 2016 creates a unique and timely opportunity to increase Indigenous children's participation in state-of-the-art clinical trials.

Assessing the Predictive Validity of the Stages of Change Readiness and Treatment Eagerness Scale (SOCRATES) in Alaska Native and American Indian People.

OBJECTIVES: The objective of this study was to examine the predictive validity of the Stages of Change Readiness and Treatment Eagerness Scale (SOCRATES) among Alaska Native and American Indian (ANAI) people with an alcohol use disorder. METHODS: The sample was 170 ANAI adults with an alcohol use disorder living in Anchorage, Alaska who were part of a larger alcohol intervention study. The primary outcome of this study was alcohol use as measured by mean urinary ethyl glucuronide (EtG). EtG urine tests were collected at baseline and then up to twice a week for four weeks. We conducted bivariate linear regression analyses to evaluate associations between mean EtG value and each of the three SOCRATES subscales (Recognition, Ambivalence, and Taking Steps) and other covariates such as demographic characteristics, alcohol use history, and chemical dependency service utilization. We then performed multivariable linear regression modeling to examine these associations after adjusting for covariates. RESULTS: After adjusting for covariates, mean EtG values were negatively associated with the Taking Steps (P = 0.017) and Recognition (P = 0.005) subscales of the SOCRATES among ANAI people living in Alaska. We did not find an association between mean EtG values and the Ambivalence subscale (P = 0.129) of the SOCRATES after adjusting for covariates. CONCLUSIONS: Higher scores on the Taking Steps and Recognition subscales of the SOCRATES at baseline among ANAI people predicted lower mean EtG values. This study has important implications for communities and clinicians who need tools to assist ANAI clients in initiating behavior changes related to alcohol use.

"You Actually View Us as the Experts in Our Own System": Indigenous-Academic Community Partnership.

BACKGROUND: The literature on community-engaged research provides important principles to guide research partnerships, but concrete descriptions of the complexities involved in developing, navigating, and maintaining such partnerships are lacking. OBJECTIVES: To describe and assess a longstanding, complex research partnership between Indigenous and academic pharmacogenetic research partners, with attention to co-learning and capacity building lessons learned. METHODS: Descriptive thematic analysis of 11 semistructured interviews with interdisciplinary research partners situated at Indigenous and academic settings. RESULTS: Lessons learned included the need for explicit negotiation around mentoring expectations, and discussion on advisory and staff roles. Partners need to be aware not only of the structures, policies, and hierarchies within each partner institution, but also the tacit value commitments and understandings entailed in their different missions. CONCLUSIONS: This study highlights that the concept of "bidirectional" learning as it is usually presented in the literature fails to capture the complexity of how partnerships work.

Culturally Adapting an Advance Care Planning Communication Intervention With American Indian and Alaska Native People in Primary Care.

Introduction: Advance care planning (ACP) is a process in which patients, families, and providers discuss and plan for desired treatment goals. American Indian and Alaska Native people (AI/AN) have higher prevalence of many serious, life-limiting illnesses compared with the general population; yet AI/ANs use ACP considerably less than the overall population. Method: We conducted a qualitative study to culturally adapt an existing ACP intervention for AI/ANs in two primary care settings. Results: We found that it is important to incorporate patients' cultural values and priorities into ACP, determine who the patient wants involved in ACP conversations, and consider the culturally and locally relevant barriers and facilitators when developing an ACP intervention with AI/AN communities. Discussion: At the core, ACP interventions should be clear and understandable across populations and tailored to facilitate culturally appropriate and meaningful patient-provider communication. Our results and methodology of culturally adapting an intervention may be applicable to other underrepresented populations.

Perceptions of alcohol misuse among Alaska native health care system stakeholders: A qualitative exploration.

Although alcohol misuse is a priority for health care systems serving Alaska Native and American Indian (ANAI) people, stakeholders' perceptions of misuse are understudied. Patients (n = 34), providers (n = 20), and leaders (n = 16) at a Tribally owned and operated health care system reported that alcohol misuse results from the interaction of factors, including colonization, structural factors, social alienation, social norms about overdrinking introduced at the time of colonizing contact, coping with emotions, and beliefs about ANAI people and alcohol. Childhood exposure to alcohol misuse leads some ANAI people to avoid alcohol altogether, shedding light on the high levels of abstinence observed in ANAI communities.

Lived Experiences of Suicide Risk and Resilience among Alaska Native and American Indian People.

This study explored the lived experiences of suicidality and help-seeking for suicide prevention among Alaska Native and American Indian (AN/AI) people in a tribal health system. An interpretive phenomenological approach was used to analyze semi-structured, in-depth interviews with 15 individuals (ages 15-56) with self-reported histories of suicide ideation and/or attempt. Several factors were found to be central to acquiring resilience to suicide risk among AN/AI people across a wide age range: meaningful and consistent social connection, awareness about how one's suicide would negatively effect loved ones, and knowledge and utilization of available health services. Findings highlight the mutable nature of suicide risk and resilience, as well as the importance of interpersonal factors in suicidality.

Retrospective eDNA assessment of potentially harmful algae in historical ship ballast tank and marine port sediments.

Microalgal bloom events can cause major ecosystem disturbances, devastate local marine economies, and endanger public health. Therefore, detecting and monitoring harmful microalgal taxa is essential to ensure effective risk management in waterways used for fisheries, aquaculture, recreational activity, and shipping. To fully understand the current status and future direction of algal bloom distributions, we need to know how populations and ecosystems have changed over time. This baseline knowledge is critical for predicting ecosystem responses to future anthropogenic change and will assist in the future management of coastal ecosystems. We explore a NGS metabarcoding approach to rapidly identify potentially harmful microalgal taxa in 63 historic and modern Australian marine port and ballast tank sediment samples. The results provide a record of past microalgal distribution and important baseline data that can be used to assess the efficacy of shipping guidelines, nutrient pollution mitigation, and predict the impact of climate change. Critically, eDNA surveys of archived sediments were able to detect harmful algal taxa that do not produce microscopic fossils, such as Chattonella, Heterosigma, Karlodinium, and Noctiluca. Our data suggest a potential increase in Australian harmful microalgal taxa over the past 30 years, and confirm ship ballast tanks as key dispersal vectors. These molecular mapping tools will assist in the creation of policies aimed at reducing the global increase and spread of harmful algal taxa and help prevent economic and public-health problems caused by harmful algal blooms.

Perspectives on communication and engagement with regard to collecting biospecimens and family health histories for cancer research in a rural Alaska Native community.

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.

Self-Determination in Health Research: An Alaska Native Example of Tribal Ownership and Research Regulation.

Alaska Native (AN) and American Indian (AI) people are underrepresented in health research, yet many decline to participate in studies due to past researcher misconduct. Southcentral Foundation (SCF), an Alaska Native-owned and operated health care organization, is transforming the relationship between researchers and the tribal community by making trust and accountability required features of health research in AN/AI communities. In 1998, SCF assumed ownership from the federal government of health services for AN/AI people in south central Alaska and transformed the health system into a relationship-based model of care. This change reimagines how researchers interact with tribal communities and established community oversight of all health research conducted with AN/AI people in the region. We describe the SCF research review process, which requires tribal approval of the research concept, full proposal, and dissemination products, as well as local institutional review board approval, and a researcher-signed contract. This review evaluates research through the lens of tribal principles, practices, and priorities. The SCF example provides a framework for other tribes and organizations seeking to reshape the future of health research in AN/AI communities.

Incorporating Transgenerational Epigenetic Inheritance into Ecological Risk Assessment Frameworks.

Chronic exposure to environmental contaminants can induce heritable "transgenerational" modifications to organisms, potentially affecting future ecosystem health and functionality. Incorporating transgenerational epigenetic heritability into risk assessment procedures has been previously suggested. However, a critical review of existing literature yielded numerous studies claiming transgenerational impacts, with little compelling evidence. Therefore, contaminant-induced epigenetic inheritance may be less common than is reported in the literature. We identified a need for multigeneration epigenetic studies that extend beyond what could be deemed "direct exposure" to F1 and F2 gametes and also include subsequent multiple nonexposed generations to adequately evaluate transgenerational recovery times. Also, increased experimental replication is required to account for the highly variable nature of epigenetic responses and apparent irreproducibility of current studies. Further, epigenetic end points need to be correlated with observable detrimental organism changes before a need for risk management can be properly determined. We suggest that epigenetic-based contaminant studies include concentrations lower than current "EC10-20" or "Lowest Observable Effect Concentrations" for the organism's most sensitive phenotypic end point, as higher concentrations are likely already regulated. Finally, we propose a regulatory framework and optimal experimental design that enables transgenerational epigenetic effects to be assessed and incorporated into conventional ecotoxicological testing.

Light as a key driver of freshwater biofouling surface roughness in an experimental hydrocanal pipe rig.

Biofouling in canals and pipelines used for hydroelectric power generation decreases the flow capacity of conduits. A pipeline rig was designed consisting of test sections of varying substrata (PVC, painted steel) and light levels (transparent, frosted, opaque). Stalk-forming diatoms were abundant in both the frosted and transparent PVC pipes but negligible in the painted steel and opaque PVC pipes. Fungi were slightly more abundant in the painted steel pipe but equally present in all the other pipes while bacterial diversity was similar in all pipes. Photosynthetically functional biofouling (mainly diatoms) was able to develop in near darkness. Different biological fouling compositions generated differing friction factors. The highest friction factor was observed in the transparent pipe (densest diatom fouling), the lowest peak friction for the opaque PVC pipe (lowest fouling biomass), and with the painted steel pipe (high fouling biomass, but composed of fungal and bacterial crusts) being intermediate between the opaque and frosted PVC pipes.

Using Amplicon Sequencing To Characterize and Monitor Bacterial Diversity in Drinking Water Distribution Systems.

Drinking water assessments use a variety of microbial, physical, and chemical indicators to evaluate water treatment efficiency and product water quality. However, these indicators do not allow the complex biological communities, which can adversely impact the performance of drinking water distribution systems (DWDSs), to be characterized. Entire bacterial communities can be studied quickly and inexpensively using targeted metagenomic amplicon sequencing. Here, amplicon sequencing of the 16S rRNA gene region was performed alongside traditional water quality measures to assess the health, quality, and efficiency of two distinct, full-scale DWDSs: (i) a linear DWDS supplied with unfiltered water subjected to basic disinfection before distribution and (ii) a complex, branching DWDS treated by a four-stage water treatment plant (WTP) prior to disinfection and distribution. In both DWDSs bacterial communities differed significantly after disinfection, demonstrating the effectiveness of both treatment regimes. However, bacterial repopulation occurred further along in the DWDSs, and some end-user samples were more similar to the source water than to the postdisinfection water. Three sample locations appeared to be nitrified, displaying elevated nitrate levels and decreased ammonia levels, and nitrifying bacterial species, such as Nitrospira, were detected. Burkholderiales were abundant in samples containing large amounts of monochloramine, indicating resistance to disinfection. Genera known to contain pathogenic and fecal-associated species were also identified in several locations. From this study, we conclude that metagenomic amplicon sequencing is an informative method to support current compliance-based methods and can be used to reveal bacterial community interactions with the chemical and physical properties of DWDSs.
