Creating a path forward: understanding the context of sexual health and sexually transmitted infections in American Indian/Alaska Native populations – a review.

This review assessed sexual health and sexually transmitted infection (STI) burden among American Indian/Alaska Native (AI/AN) peoples within the context of current clinical and public health services. We conducted a review of published literature about sexual health and bacterial STIs among AI/AN populations in the United States using Medline (OVID), CINAHL (EbscoHost) and Scopus. Peer-reviewed journals published during 1 January 2005-2 December 2021 were included and supplemented by other publicly available literature. A total of 138 articles from reference lists met inclusion criteria, including 85 peer-review articles and 53 additional references. Results indicate a disproportionate burden of STIs is carried by AI/AN populations compared to non-Hispanic Whites. Risk for STIs in AI/AN people has origins in historical trauma and structural and social determinants of health. STI services are available for AI/AN populations, but many barriers to care exist. Community-based sexual health programming has been successful, but has thus far focused primarily on adolescents and young adults. A myriad of factors contributes to high rates of STIs among AI/AN populations. Longstanding disparities show a clear need to increase the availability of integrated, low-barrier STI prevention and treatment services. Implementation of multi-level (individual, physician, clinic, healthcare organisation, and/or community level), culturally relevant sexual health and STI interventions should be community-based and person-centred, acknowledge social determinants of health, and grounded in deep respect and understanding of AI/AN histories and cultures.

Implementation and evaluation of a Project ECHO telementoring program for the Namibian HIV workforce.

BACKGROUND: The Namibian Ministry of Health and Social Services (MoHSS) piloted the first HIV Project ECHO (Extension for Community Health Outcomes) in Africa at 10 clinical sites between 2015 and 2016. Goals of Project ECHO implementation included strengthening clinical capacity, improving professional satisfaction, and reducing isolation while addressing HIV service challenges during decentralization of antiretroviral therapy. METHODS: MoHSS conducted a mixed-methods evaluation to assess the pilot. Methods included pre/post program assessments of healthcare worker knowledge, self-efficacy, and professional satisfaction; assessment of continuing professional development (CPD) credit acquisition; and focus group discussions and in-depth interviews. Analysis compared the differences between pre/post scores descriptively. Qualitative transcripts were analyzed to extract themes and representative quotes. RESULTS: Knowledge of clinical HIV improved 17.8% overall (95% confidence interval 12.2-23.5%) and 22.3% (95% confidence interval 13.2-31.5%) for nurses. Professional satisfaction increased 30 percentage points. Most participants experienced reduced professional isolation (66%) and improved CPD credit access (57%). Qualitative findings reinforced quantitative results. Following the pilot, the Namibia MoHSS Project ECHO expanded to over 40 clinical sites by May 2019 serving more than 140 000 people living with HIV. CONCLUSIONS: Similar to other Project ECHO evaluation results in the United States of America, Namibia's Project ECHO led to the development of ongoing virtual communities of practice. The evaluation demonstrated the ability of the Namibia HIV Project ECHO to improve healthcare worker knowledge and satisfaction and decrease professional isolation.

Hepatitis C drug prescriptions and Medicaid policies--four states, Indian health care system, USA 2018.

Medicaid, the state-level public insurance in the United States, has widely differing criteria treatment for hepatitis C virus (HCV) such as stage of liver fibrosis, documented sobriety, and specialist consultation. In a rural health network, facilities located in two less restrictive states prescribed HCV drugs at a significantly higher rate than two more restrictive states (rate ratio 4.7, CI 2.6-8.5). Prescription rates per population were highly associated with HCV treatment policies.

An Evaluation of Hepatitis C Virus Telehealth Services Serving Tribal Communities: Patterns of Usage, Evolving Needs, and Barriers.

INTRODUCTION: American Indian/Alaska Native (AI/AN) populations are disproportionately affected by chronic hepatitis C virus (HCV) infection. Federal facilities of the Indian Health Service, in conjunction with Tribally operated and Urban Indian (I/T/U) health care facilities, serve an estimated 2.2 million AI/AN patients. The facilities are mainly rural and have few specialists. To fill the gap in specialists in I/T/U clinics, the Extension for Community Healthcare Outcomes (ECHO) telehealth model was used to support clinicians to treat HCV in primary care. METHODS: Participants in 3 regional HCV ECHO networks serving AI/AN patients were surveyed by e-mail and text message to determine patterns of ECHO usage, usefulness, and barriers to treating patients with HCV at their primary care clinics. RESULTS: From a total of 44 respondents from 72 eligible health care facilities, a majority (61%) stated that they started treating patients with HCV subsequent to participating in the telehealth program. Participants with more telehealth experience sought increasing complexity in patient case presentations. In California, 7 of 8 clinicians who had attended more than 10 ECHO sessions expressed diminishing need for ECHO sessions to manage cases (<25% of patients). All elements of the ECHO sessions (presenting patient cases, listening to patient case presentations, teaching sessions, and sharing of programmatic insights) were considered "extremely useful" by the majority of respondents. The factors most cited as moderate or extensive barriers to providing HCV care were access to HCV direct acting antivirals (60%) and linking patients to care (50%). DISCUSSION: Extension for Community Healthcare Outcomes may play a key role not only in increasing clinical capacity for HCV treatment but also in the inception of HCV services in this sample of I/T/U facilities. Participants with more telehealth experience demonstrated signs of increasing clinical capacity, where they were more likely to seek complex patient case presentations in ECHO sessions. A number of barriers continue to keep AI/ANs from being cured and stop clinicians from ending the epidemic, including access to HCV medications, time to provide HCV clinical services, and linking patients to HCV services.

Incidence of primary liver cancer in American Indians and Alaska Natives, US, 1999-2009.

PURPOSE: To evaluate liver cancer incidence rates and risk factor correlations in non-Hispanic AI/AN populations for the years 1999-2009. METHODS: We linked data from 51 central cancer registries with the Indian Health Service patient registration databases to improve identification of the AI/AN population. Analyses were restricted to non-Hispanic persons living in Contract Health Service Delivery Area counties. We compared age-adjusted liver cancer incidence rates (per 100,000) for AI/AN to white populations using rate ratios. Annual percent changes (APCs) and trends were estimated using joinpoint regression analyses. We evaluated correlations between regional liver cancer incidence rates and risk factors using Pearson correlation coefficients. RESULTS: AI/AN persons had higher liver cancer incidence rates than whites overall (11.5 versus 4.8, RR = 2.4, 95% CI 2.3-2.6). Rate ratios ranged from 1.6 (Southwest) to 3.4 (Northern Plains and Alaska). We observed an increasing trend among AI/AN persons (APC 1999-2009 = 5%). Rates of distant disease were higher in the AI/AN versus white population for all regions except Alaska. Alcohol use (r = 0.84) and obesity (r = 0.79) were correlated with liver cancer incidence by region. CONCLUSIONS: Findings highlight disparities in liver cancer incidence between AI/AN and white populations and emphasize opportunities to decrease liver cancer risk factor prevalence.

Assessing Disparities in the Rates of HCV Diagnoses Within American Indian or Alaska Native Populations Served by the U.S. Indian Health Service, 2005-2015.

Hepatitis C virus (HCV) disproportionately affects American Indians/Alaska Natives (AI/AN). The Indian Health Service (IHS), via federal and tribal health facilities provides medical services to an estimated 2.2 million AI/AN people in the United States. HCV diagnoses, defined by International Classification of Diseases 9th Revision, Clinical Modification (ICD-9-CM) codes, were analyzed from 2005 to 2015. Results showed 29,803 patients with an HCV diagnosis; 53.4% were among persons born 1945-1965 and overall HCV burden was higher among males than females. These data will help inform local, regional, and national efforts to address, plan for and carry out a national strategy to provide treatment for HCV infected patients and programs to prevent new HCV infections.

Birth Cohort Testing for Hepatitis C Virus - Indian Health Service 2012-2015.

Hepatitis C virus (HCV) infection is a substantial and largely unrecognized public health problem. An estimated 3.5 million persons in the United States are currently living with HCV infection, at least half of whom are unaware of their infection (1-3). Persons born during 1945-1965 (the "baby boomer" birth cohort) have a sixfold higher prevalence (2.6%) than adults of other ages, and represent 81% of all persons chronically infected with HCV (4). Therefore, in addition to recommending testing for all persons at risk for HCV infection, CDC and the U.S. Preventive Services Task Force (USPSTF) recommend one-time HCV testing for the birth cohort (5,6). Compared with the national average, American Indian/Alaska Native (AI/AN) persons have approximately twofold the rate of acute HCV incidence and HCV associated mortality (2). In June 2012, the Indian Health Service (IHS) implemented HCV testing in the 1945-1965 birth cohort and created a nationally standardized performance measure to monitor implementation of the recommendation. As of June 2015, the proportion of the birth cohort screened for HCV increased from a baseline of 7.9% (14,402/182,503) to 32.5% (68,514/211,014) among the AI/AN population served by IHS nationwide; provider training and the use of clinical decision tools were associated with increases in HCV testing. With this fourfold increase in testing in just 3 years, IHS needs to prepare for the challenges associated with increased identification of persons living with HCV infection.

Identification and Clinical Management of Persons with Chronic Hepatitis C Virus Infection - Cherokee Nation, 2012-2015.

An estimated 3.5 million persons in the United States are living with hepatitis C virus (HCV) infection, resulting in approximately 20,000 deaths each year, primarily from cirrhosis or hepatocellular carcinoma (1,2). American Indian/Alaska Native (AI/AN) populations have the highest incidence of acute HCV infection among all U.S. racial/ethnic groups and are at greater risk for HCV-related mortality compared with the general population (3). In 2013, new antiviral drugs became available that make possible 8-12 week treatment regimens with fewer adverse events and are able to achieve sustained virologic response (SVR) in >90% of treated patients (4), equivalent to a cure of HCV infection. Also of note, HCV testing recommendations were expanded in 2012 by CDC and in 2013 by the U.S. Preventive Services Task Force to include one-time testing of persons born during 1945-1965 (the "baby boomer" cohort) in addition to anyone at increased risk for HCV infection (5,6). Given the availability of new HCV drugs, expanded testing recommendations, and high incidence of HCV infection in AI/AN populations, in October 2012, Cherokee Nation Health Services (CNHS) implemented a tribal HCV testing policy.* As part of the policy, CNHS added a reminder in the electronic health record (EHR) for clinical decision support and provided HCV education to primary care clinicians. From October 2012 to July 2015, among 92,012 persons with at least one CNHS clinic encounter, the cumulative number who received HCV screening for the first time increased from 3,337 (3.6%) to 16,772 (18.2%). The largest percentage of HCV screening was among persons born during 1945-1965. Of 715 persons who tested positive for HCV antibodies, 488 (68.3%) were tested for HCV RNA; among those 488 persons, 388 (79.5%) were RNA positive and were thus confirmed to have chronic HCV infection. Treatment was initiated for 223 (57.5%) of the 388 with chronic infection; 201 (90.1%) completed treatment, of whom 180 (89.6%) achieved SVR. CNHS has successfully increased HCV testing and treatment and is now collaborating with CDC and other external partners to develop an HCV elimination program for the Cherokee Nation that might serve as a model for similar settings.

Ectopic pregnancy among American Indian and Alaska Native women, 2002-2009.

To examine rates of ectopic pregnancy (EP) among American Indian and Alaska Native (AI/AN) women aged 15-44 years seeking care at Indian Health Service (IHS), Tribal, and urban Indian health facilities during 2002-2009. We used 2002-2009 inpatient and outpatient data from the IHS National Patient Information Reporting System to identify EP-associated visits and obtain the number of pregnancies among AI/AN women. Repeat visits for the same EP were determined by calculating the interval between visits; if more than 90 days between visits, the visit was considered related to a new EP. We identified 229,986 pregnancies among AI/AN women 15-44 years receiving care at IHS-affiliated facilities during 2002-2009. Of these, 2,406 (1.05 %) were coded as EPs, corresponding to an average annual rate of 10.5 per 1,000 pregnancies. The EP rate among AI/AN women was lowest in the 15-19 years age group (5.5 EPs per 1,000 pregnancies) and highest among 35-39 year olds (18.7 EPs per 1,000 pregnancies). EP rates varied by geographic region, ranging between 6.9 and 24.4 per 1,000 pregnancies in the Northern Plains East and the East region, respectively. The percentage of ectopic pregnancies found among AI/AN women is within the national 1-2 % range. We found relatively stable annual rates of EP among AI/AN women receiving care at IHS-affiliated facilities during 2002-2009, but considerable variation by age group and geographic region. Coupling timely diagnosis and management with public health interventions focused on tobacco use and sexually transmitted diseases may provide opportunities for reducing EP and EP-associated complications among AI/AN women.

Death rates from human immunodeficiency virus and tuberculosis among American Indians/Alaska Natives in the United States, 1990-2009.

OBJECTIVES: We used race-corrected data and comprehensive diagnostic codes to better compare HIV and tuberculosis (TB) mortality from 1999 to 2009 between American Indian/Alaska Natives (AI/ANs) and Whites. METHODS: National Vital Statistics Surveillance System mortality data were adjusted for AI/AN racial misclassification through linkage with Indian Health Service registration records. We compared average annual 1990 to 2009 HIV and TB death rates (per 100,000 people) for AI/AN persons with those for Whites; Hispanics were excluded. RESULTS: Although death rates from HIV in AI/AN persons were significantly lower than those in Whites from 1990 to 1998 (4.2 vs 7.0), they were significantly higher than those in Whites from 1999 to 2009 (3.6 vs 2.0). Death rates from TB in AI/AN persons were significantly higher than those in Whites, with a significant disparity during both 1990 to 1998 (3.3 vs 0.3) and 1999 to 2009 (1.5 vs 0.1). CONCLUSIONS: The decrease in death rates from HIV and TB was greater among Whites, and death rates remained significantly higher among AI/AN individuals. Public health interventions need to be prioritized to reduce the TB and HIV burden and mortality in AI/AN populations.

Lack of access to treatment as a barrier to HCV screening: a facility-based assessment in the Indian health service.

The US Centers for Disease Control and Prevention recently issued new recommendations to screen persons born between 1945 and 1965 for hepatitis C virus. Federal facilities in the US Indian Health Service were surveyed on knowledge and support for the hepatitis C virus recommendations, as well as barriers and concerns.

Evaluation of treatment access and scope of a multistate hepatitis C virus Extension for Community Healthcare Outcomes telehealth service in the US Indian Health System, 2017-2021.

PURPOSE: American Indians/Alaska Native (AI/AN) persons are disproportionately affected by hepatitis C virus (HCV). The Northwest Portland Area Indian Health Board Indian Country Extension for Community Healthcare Outcomes (ECHO) telehealth clinic supports primary care providers (PCPs) in treating HCV. We evaluated the extent to which Indian Country ECHO increases access to HCV treatment and holistically serves AI/AN patients. METHODS: We conducted a retrospective descriptive analysis of Indian Country ECHO treatment recommendations from 2017 to 2021. Recommendations were classified into the following categories: HCV treatment with direct-acting antiviral medication, prevention, substance use disorder treatment, lab or imaging orders, pharmacological considerations, behavior changes, other, and referral. Subanalysis of treatment recommendations was completed for patients with cirrhosis. FINDINGS: Of the 776 patients from 77 Indian Health System facilities who presented at Indian Country ECHO, 718 (93%) received treatment recommendations. Most patients (93%) received recommendations for HCV treatment by their PCP; only 3% received a recommendation for referral to a hepatologist or liver transplant center for additional care. Most patients received at least 1 recommendation beyond the scope of HCV treatment provision. Cirrhosis criteria were met by 8% of patients, of which 80% received recommendations for HCV treatment by their PCP and 25% received recommendations for referral to a specialist for additional care. CONCLUSIONS: Most patients presented at the Indian Country ECHO received recommendations for HCV treatment by their PCP, along with recommendations beyond the scope of HCV. Indian Country ECHO telehealth clinic provides comprehensive recommendations to effectively integrate evidence-based HCV treatment with holistic care at the primary care level.

Adapting a Telehealth Network for Emergency COVID-19 Pandemic Response, 2020-2021.

In March 2020, a Tribal telehealth program-the Indian Country Extension for Community Health Outcomes (ECHO)-added emergency COVID-19 to its programming to support the pandemic response. A long-standing relationship with a network of Indian Health Service, Tribal, and urban Indian clinicians supported a rapid launch of the COVID-19 telehealth program. This nationwide service offered primary care clinicians and staff serving American Indian/Alaska Native people access to virtual learning opportunities, expert clinical recommendations, technical assistance, and capacity building. From March 12, 2020, through April 30, 2021, the program provided 85 clinical sessions in 12 months, with an average participation of 120 attendees per clinic (N = 11 710). Attendees could complete a voluntary evaluation form for each session via an online link. A total of 2595 forms were completed. Attendees came from 33 states and 206 unique locations, primarily from the Pacific Northwest (n = 931, 35.9%). Most pharmacists (78.1%), providers (ie, medical doctor, doctor of osteopathy, advanced practice nurse, physician assistant, or clinical nurse midwife; 70.8%), and nurses (59.6%) gave the sessions the highest rating of "very satisfied." The highest proportion of attendees indicating that they planned a change in practice were pharmacists (68.0%), nurses, (64.1%), and providers (61.3%). Most attendees (93.1%) said that the COVID-19 sessions gave them a sense of social support. Lessons learned were that (1) a telehealth platform can be quickly retasked for emergency response with no further delays, (2) a telehealth network can be scaled up quickly with participation from preexisting relationships, and (3) the platform is flexible and adaptable to the needs of participants. An existing telehealth program can be a key part of timely, relevant, large-scale emergency readiness and response efforts.

Identifying opportunities for chlamydia screening among American Indian women.

Medical record review was used to identify missed opportunities for chlamydia screening among 103 American Indian/Alaska Native women. Of these, 69% had received a pregnancy test and 74% had received a urine test in the previous 12 months. Chlamydia screening may increase if linked to the other routine clinical testing.

Validation of algorithm to identify American Indian/Alaska Native pregnant women at risk from pandemic H1N1 influenza.

Pregnant women and American Indian and Alaska Native people are at elevated risk of severe disease and mortality from 2009 pandemic influenza A/H1N1. We validated an electronic health record-based algorithm used by Indian Health Service to identify pregnant women in near real-time surveillance of pandemic influenza A/H1N1. We randomly selected a stratified sample of 515 patients at 3 Indian Health Service-funded hospitals with varied characteristics. With comprehensive review of patients' electronic health records as the gold standard, we calculated the positive predictive value and sensitivity of the pregnancy algorithm. The sensitivity of the algorithm at individual hospitals ranged from 94.1-96.0%. Positive predictive value ranged from 94.4-98.3%. Despite differences among hospitals on key characteristics, the pregnancy algorithm performed nearly equivalently with high positive predictive value and sensitivity at all facilities. It may prove helpful for surveillance during future epidemics and for targeting interventions for pregnant women and infants.

A review of missed opportunities for prenatal HIV screening in a nationwide sample of health facilities in the Indian Health Service.

To better serve our patients, we sought to identify missed opportunities for prenatal HIV screening across Indian Health Service and potential ways to increase screening. Twenty-seven of 161 Federal or Tribal IHS health facilities were randomly selected. Each facility received a standardized set of commands to identify the charts of prenatal patients who were not screened for HIV according to the national Health Information Technology (HIT) platform. We reviewed 598 records at 27 sites of prenatal patients who were identified as not screened for HIV during their pregnancy. According to on-site chart review, nearly half (267/598, 45%) had been screened for HIV, and a slight majority (331/598, 55%) had not been screened. Among the 331 pregnant women not screened for HIV, about half had no HIV screening despite having had ≥2 prenatal care encounters and no screening exclusions (167/331, 50%). A majority of missed opportunities (118/167, 71%) had prenatal testing for other infectious diseases. Based on these results, the National HIV/AIDS program has encouraged increased bundling of HIV with infectious disease tests in prenatal laboratory panels. Improvements in documentation of HIV screening are expected with the IHS transition to electronic health records.

Electronic Health Record Reminders for Chlamydia Screening in an American Indian Population.

OBJECTIVES: Indian Health Service (IHS) screening rates for Chlamydia trachomatis are lower than national rates of chlamydia screening in the Southwest. We describe and evaluate the effect of a public health intervention consisting of electronic health record (EHR) reminders to alert health care providers to screen for chlamydia at an IHS facility. We also conducted an awareness presentation among health care providers on chlamydia screening. METHODS: We conducted our intervention from November 1, 2013, through October 31, 2015, at an IHS facility in the Southwest. We implemented algorithms that queried database values to assess chlamydia screening performance in 6 clinical departments. We presented data on the screening performance of clinical departments and health care providers (de-identified) in the awareness presentations. We re-queried database values 1 and 2 years after implementation of the EHR reminder intervention to evaluate before-and-after screening rates, comparing data among all patients and among female patients only. RESULTS: We found small, sustained relative increases in chlamydia screening rates during the 2012-2015 evaluation period: 20.8% pre-intervention to 24.9% and 24.2% one and two years postintervention, respectively, across all patients; 32.3% preintervention to 36.6% and 35.6% one and two years postintervention, respectively, among female patients. Increases in clinical department-specific screening rates varied and were most prominent in internal medicine (35.8% preintervention to peak 65.8% postintervention). The 1 clinic (obstetrics-gynecology) that did not receive an awareness presentation showed a consistent downward trend in screening rates, although absolute rates were consistently higher in that clinic than in other clinics. CONCLUSIONS: Awareness presentations that offer feedback to health care providers on screening performance, heighten provider awareness of the importance of chlamydia screening, and promote development of novel provider-initiated screening protocols may help to increase screening rates when combined with EHR reminders.

Physician and nurse perspectives on implementation of universal adult HIV screening guidelines in the Indian health service: results of a randomized survey.

OBJECTIVES: We sought to determine attitudes and needs among health care providers in the Indian Health Service toward implementing routine human immunodeficiency virus (HIV) screening among 13- to 64-year-olds as per Centers for Disease Control and Prevention (CDC) guidelines. METHODS: We surveyed a random sample of Indian Health Service physicians and nurses by e-mail and telephone interview. A total of 205 eligible respondents (response rate = 70%) completed the survey. RESULTS: A majority (58%) of respondents were familiar or somewhat familiar with the 2006 CDC guidelines on HIV screening for 13- to 64-year-olds. A proportion of respondents (43%) felt that community HIV prevalence was below the 0.1% threshold the CDC recommends to initiate screening. Respondents supported routine, rather than solely risk-based HIV testing (70%) and stated that HIV screening would be realistic in their health facility (51%). Respondents felt that they needed special qualification to offer an HIV test (49%) or to notify a patient of a "reactive" HIV test result (67%). CONCLUSIONS: A majority of Indian Health Service physicians and nurses support the CDC HIV screening guidelines. Providers need more information and training on HIV screening guidelines, implementation strategies, and relevant state HIV regulations.
