COVID-19 vaccine uptake among non-US-born populations in the United States, 2020-2022.

BACKGROUND: In the United States (US), COVID-19 vaccination rates among non-US-born individuals (i.e., refugees, immigrants, and migrants [RIM]) are variable. Understanding baseline COVID-19 vaccine coverage among these populations and determining if disparities exist is essential for quality improvement initiatives and public health interventions. METHODS: Baseline COVID-19 vaccination rates for both primary series and booster doses were calculated at four health systems located in Minnesota, Colorado, and Pennsylvania participating in the Minnesota Department of Health's Center of Excellence in Newcomer Health. Patients aged ≥5 years as of 1/1/22, seen for ≥1 primary care visit during 7/1/2019-6/30/22 were included. Descriptive statistics were calculated for three measures of COVID-19 vaccine coverage during 12/14/2020-6/30/2022: 1) initiation of primary series; 2) completion of primary series; 3) completion of first booster. We calculated vaccine coverage rates for the entire population and stratified by subgroup including country of origin, refugee status, and primary language preference. RESULTS: We included 1,624,573 patients eligible for COVID-19 primary series vaccine and 907,749 eligible for COVID-19 booster vaccination. The percent of eligible patients who completed a COVID-19 primary series (63.4 %) and booster dose (66.2 %) were similar. Completion of the primary series was higher for non-US-born persons (72.7 %) compared with US born persons (65.4 %), similar among refugees (63.5 %) and non-refugees (63.4 %), and lower in patients with language preference other than English (62.7 %) compared with English preferring patients (63.6 %). Booster completion was lower for non-US-born persons (61.8 %), refugees (46.7 %), and patients with language preference other than English (55.3 %) compared with US-born (70 %), non-refugees (66.3 %), and English preferring patients (67.3 %) respectively. CONCLUSIONS: This evaluation identified disparities in COVID-19 vaccination rates among non-US-born persons and persons with a language preference other than English living in the US. Targeted outreach efforts may be beneficial in reaching these populations.

Health Risks of Unaccompanied Immigrant Children in Federal Custody and in US Communities.

Unaccompanied immigrant children continue to arrive at the US-Mexico border and are at high risk for ongoing abuse, neglect, and poor mental and physical health. We are medical and legal experts in the fields of immigrant and refugee health, child abuse, and the legal rights of international refugee and migrant children. We provide an overview of US federal agencies with custody of unaccompanied immigrant children, a summary of medical care provided while in custody, and recent findings from the independent Juvenile Care Monitor Report mandating new custodial conditions for immigrant children while in federal custody. We provide recommendations to improve the health and well-being of unaccompanied immigrant children while in custody and once released to US sponsors.

Health Care for Children in Immigrant Families: Key Considerations and Addressing Barriers.

One in four US children is a child in an immigrant family. Children in immigrant families (CIF) have distinct health and health care needs that vary by documentation status, countries of origin, and health care and community experience caring for immigrant populations. Health insurance access and language services are fundamental to providing health care to CIF. Promoting health equity for CIF requires a comprehensive approach to both the health and social determinants of health needs of CIF. Child health providers can promote health equity for this population through tailored primary care services and partnerships with immigrant-serving community organizations.

Increasing COVID-19 Vaccination Coverage for Newcomer Communities: The Importance of Disaggregation by Language.

The COVID-19 pandemic has disproportionately affected refugee, immigrant, and migrant populations. Vaccines are essential for decreasing transmission and severity of COVID-19 infection. Understanding differences in vaccination coverage based on preferred language is crucial for focusing efforts to decrease COVID-19-related disparities. Four sites in the Minnesota Center of Excellence in Newcomer Health collaboratively evaluated completion of primary COVID-19 vaccination series on or before December 31, 2021, for patients who were 12 years or older on June 30, 2021, by preferred language. The non-English/non-Spanish speaking population included 46,714 patients who spoke 174 languages; COVID-19 vaccination coverage by language ranged from 26.2% to 88.0%. Stratifying vaccination coverage by specific language is a critical first step toward dismantling disparities and shaping interventions that best meet the needs of communities served.

Hepatitis C Screening and Antibody Prevalence Among Newly Arrived Refugees to the United States, 2010-2017.

Six refugee screening sites collaborated to estimate the prevalence of hepatitis C virus (HCV) antibodies among newly arrived refugees in the United States from 2010 to 2017, identify demographic characteristics associated with HCV antibody positivity, and estimate missed HCV antibody-positive adults among unscreened refugees. We utilized a cross-sectional study to examine HCV prevalence among refugees (N = 144,752). A predictive logistic regression model was constructed to determine the effectiveness of current screening practices at identifying cases. The prevalence of HCV antibodies among the 64,703 refugees screened was 1.6%. Refugees from Burundi (5.4%), Moldova (3.8%), Democratic Republic of Congo (3.2%), Burma (2.8%), and Ukraine (2.0%) had the highest positivity among refugee arrivals. An estimated 498 (0.7%) cases of HCV antibody positivity were missed among 67,787 unscreened adults. The domestic medical examination represents an opportunity to screen all adult refugees for HCV to ensure timely diagnosis and treatment.

Exploitation, Labor and Sex Trafficking of Children and Adolescents: Health Care Needs of Patients.

Exploitation and labor and sex trafficking of children and adolescents is a major public health problem in the United States and throughout the world. Significant numbers of US and non-US-born children and adolescents (including unaccompanied immigrant minors) are affected by this growing concern and may experience a range of serious physical and mental health problems associated with human trafficking and exploitation (T/E). Despite these considerations, there is limited information available for health care providers regarding the nature and scope of T/E and how providers may help recognize and protect children and adolescents. Knowledge of risk factors, recruitment practices, possible indicators of T/E, and common medical, mental, and emotional health problems experienced by affected individuals will assist health care providers in recognizing vulnerable children and adolescents and responding appropriately. A trauma-informed, rights-based, culturally sensitive approach helps providers identify and treat patients who have experienced or are at risk for T/E. As health care providers, educators, and leaders in child advocacy and development, pediatricians play an important role in addressing the public health issues faced by children and adolescents who experience exploitation and trafficking. Working across disciplines with professionals in the community, health care providers can offer evidence-based medical screening, treatment, and holistic services to individuals who have experienced T/E and assist vulnerable patients and families in recognizing signs of T/E.

Characteristics and scope of humanitarian relief forensic medical evaluations for immigrant children in the US.

According to US Customs and Border Protection, over 473,000 family units and 76,000 unaccompanied children were apprehended in 2019, a multi-fold increase from previous years. Thus, the number of children who may be eligible for humanitarian relief has increased significantly. For those claiming humanitarian relief, forensic medical evaluations performed by health professionals can provide critical evidence to bolster claims. In this cross-sectional, nationwide survey-in which we sought to characterize specialties, forensic training, capacity, and scope of humanitarian relief evaluations for immigrant children under eighteen-years-old-only 28 providers, half of whom were Child Abuse Pediatricians, reported performing humanitarian relief evaluations. The most common reported type of humanitarian relief evaluation conducted was for asylum. We found that the current training for forensic medical evaluations for humanitarian relief in pediatrics is likely varied not well-defined, and not pediatric-specific. In order to protect the rights of children who are eligible for humanitarian relief, pediatric and family medicine forensic medical evaluation training standards and curricula need to be developed; validated humanitarian relief screening tools need to be tested and utilized; and residents and attending physicians, including specialists with expertise in forensic evaluations, need to be actively recruited to perform these evaluations in collaboration with legal aid organizations.

Hepatitis B Evaluation and Linkage to Care for Newly Arrived Refugees: A Multisite Quality Improvement Initiative.

A quality improvement collaborative evaluated Hepatitis B virus (HBV) care for resettled refugees and identified strategies to enhance care. 682 of the 12,934 refugees from five refugee health clinics in Colorado, Minnesota, and Pennsylvania had chronic HBV. Timely care was defined relative to a HBsAg + result: staging (HBV DNA, hepatitis Be antigen, hepatitis Be antibody, alanine transaminase testing) within 14 days, comorbid infection screening (hepatitis C virus and HIV) within 14 days, and linkage to care (HBV specialist referral within 30 days and visit within 6 months). Completed labs included: HBV DNA (93%), hepatitis Be antigen (94%), hepatitis Be antibody (92%), alanine transaminase (92%), hepatitis C screening (86%), HIV screening (97%). 20% had HBV specialist referrals within 30 days; 36% were seen within 6 months. Standardized reflex HBV testing and specialist referral should be prioritized at the initial screening due to the association with timely care.

A Denver Refugee Clinic Blood Lead Level Analysis in Refugee Females of Reproductive Age, 13-45 years, 2014-2019.

The objective was to determine if refugee females of reproductive age (FRA) are at risk of having elevated blood lead levels (BLL). A retrospective quality improvement project conducted at a Denver community health center (9/2014-3/2019) evaluated BLLs from initial domestic medical examinations (DME) in 312 FRA refugees (13-45 years). Associations between elevated BLL and demographic factors were explored using multivariable regression analysis. Of 312 FRA refugees, BLLs ranged from < 2.0 to 26.2 mcg/dL, 5% had elevated BLLs. Of pregnant refugees (49), 4% had elevated BLLs. Afghani country of origin was positively associated with elevated BLLs, adjusting for age (FRA: Prevalence Ratio 6.90 [2.68-17.77], p < 0.0001). Afghani FRA refugees, irrespective of pregnancy and breast-feeding status, should have BLL testing at DME. Nationally representative evaluations of FRA refugees are needed to determine if BLL screening should be expanded to all FRA refugees, irrespective of pregnancy or breast-feeding status.

Interferon-Gamma Release Assay Testing in Children Younger Than 2 Years in a US-Based Health System.

BACKGROUND: Use of interferon-gamma releasing assays (IGRAs) in children <2 years old may derive many of the same advantages, which have led to preference over tuberculin skin test (TST) in older children, but data are limited. Since 2011, we have tested children <2 years old with Quantiferon-TB Gold/Gold Plus (QFT)) in select clinical scenarios at Denver Health, a health system encompassing a TB clinic, refugee and immigrant screening and primary care. METHODS: We identified patients <2 years old tested with QFT between February, 2011 and August, 2019. The primary outcome measure was incident cases of TB among tested patients. Test results and in vitro characteristics were analyzed, as were demographic, epidemiologic and clinical outcomes. RESULTS: We analyzed 116 QFTs ordered in children age 7-23 months. Two were positive, 3 indeterminate, 3 failed/refused phlebotomy and the remainder (93%) were negative. Mitogen tube results were robust. Thirteen patients were TST-positive: 11 were QFT-negative, 1 QFT-positive and 1 failed phlebotomy. Eight patients received some form of TB medication, including 4 QFT-negative patients who were treated for active TB or latent TB infection based on positive TST or clinical findings. Among QFT-negative patients, including 6 TST-positive, not treated for active TB or latent TB infection, no TB disease has been identified over a median follow-up time of 2.96 years. CONCLUSIONS: IGRA use was not limited by barriers of phlebotomy, indeterminate result or gamma-interferon production. The risk of missing an infected but IGRA-negative patient can be reduced by treatment of select patients at higher risk. Current recommendations against IGRA use in children <2 years old could be amended to allow careful introduction, particularly among well-appearing BCG-vaccinated patients.

Diagnosis, Management, and Treatment of Female Genital Mutilation or Cutting in Girls.

Female genital mutilation or cutting (FGM/C) involves medically unnecessary cutting of parts or all of the external female genitalia. It is outlawed in the United States and much of the world but is still known to occur in more than 30 countries. FGM/C most often is performed on children, from infancy to adolescence, and has significant morbidity and mortality. In 2018, an estimated 200 million girls and women alive at that time had undergone FGM/C worldwide. Some estimate that more than 500 000 girls and women in the United States have had or are at risk for having FGM/C. However, pediatric prevalence of FGM/C is only estimated given that most pediatric cases remain undiagnosed both in countries of origin and in the Western world, including in the United States. It is a cultural practice not directly tied to any specific religion, ethnicity, or race and has occurred in the United States. Although it is mostly a pediatric practice, currently there is no standard FGM/C teaching required for health care providers who care for children, including pediatricians, family physicians, child abuse pediatricians, pediatric urologists, and pediatric urogynecologists. This clinical report is the first comprehensive summary of FGM/C in children and includes education regarding a standard-of-care approach for examination of external female genitalia at all health supervision examinations, diagnosis, complications, management, treatment, culturally sensitive discussion and counseling approaches, and legal and ethical considerations.

Evaluation of a Program to Improve Linkage to and Retention in Care Among Refugees with Hepatitis B Virus Infection - Three U.S. Cities, 2006-2018.

An estimated 257 million persons worldwide have chronic hepatitis B virus (HBV) infection (1). CDC recommends HBV testing for persons from countries with intermediate to high HBV prevalence (≥2%), including newly arriving refugees (2). Complications of chronic HBV infection include liver cirrhosis and hepatocellular carcinoma, which develop in 15%-25% of untreated adults infected in infancy or childhood (3). HBV-infected patients require regular monitoring for both infection and sequelae. Several studies have evaluated initial linkage to HBV care for both refugee and nonrefugee immigrant populations (4-9), but none contained standardized definitions for either linkage to or long-term retention in care for chronic HBV-infected refugees. To assess chronic HBV care, three urban sites that perform refugee domestic medical examinations and provide primary care collaborated in a quality improvement evaluation. Sites performed chart reviews and prospective outreach to refugees with positive test results for presumed HBV infection during domestic medical examinations. Linkage to care (29%-53%), retention in care (11%-21%), and outreach efforts (22%-71% could not be located) demonstrated poor access to initial and ongoing HBV care. Retrospective outreach was low-yield. Interventions that focus on prospective outreach and addressing issues related to access to care might improve linkage to and retention in care.

Female Genital Mutilation/Cutting-Pediatric Physician Knowledge, Training, and General Practice Approach.

Female genital mutilation/cutting (FGM/C) is outlawed in much of the world but still mainly occurs from infancy-age 15. Many at-risk and FGM/C-affected girls live in the US. No standard pediatric training exists. A questionnaire assessing FGM/C education, knowledge, diagnostic confidence and external genital examination (EGE) approach was sent to pediatric listservs at 3 hospitals and a child abuse pediatrician (CAP) network. Analysis used χ2 and Fisher's exact tests. Compared to general pediatricians, CAP reported more FGM/C education (RR 2.0 [95% CI 1.3-3.2]), awareness of ICD-9/10 codes (RR 3.2 [95% CI 1.4-7.3]), confidence in identifying sub-types (RR 4.5 [95% CI 2.3-8.7]) and discussing FGM/C (RR 4.2 [95% CI 2.3-7.6]). For 6-12 month olds, 10% of general pediatricians reported never performing EGE at female well child visits (WCV), increasing to > 50% for 17-18 year olds. Pediatric physicians are not trained to diagnose or manage FGM/C. EGE are not done at WCVs and FGM/C diagnoses are missed.

Better Completion of Pediatric Latent Tuberculosis Treatment Using 4 Months of Rifampin in a US-based Tuberculosis Clinic.

BACKGROUND: Children less than 5 years of age have the highest age-specific rate of progression from latent tuberculosis infection (LTBI) to active disease. Therefore, regimens for treatment of pediatric LTBI must be not only efficacious but practical enough to overcome the unique childhood barriers to regimen adherence. Since 2012, a 4-month regimen of daily rifampin (4R) has been the standard recommendation for pediatric LTBI at the Denver Metro Tuberculosis Clinic. METHODS: Using univariate and multivariate analyses, we compared treatment completion rates between 4R and 9-month isoniazid (9H) regimens for all pediatric patients treated for LTBI at the Denver Metro Tuberculosis Clinic between January 1, 2006, and December 31, 2015, and assessed the influence of clinical and demographic characteristics on successful completion of the 2 regimens. RESULTS: There were 395 children in the 4R cohort and 779 in the 9H cohort. Completion rates overall were significantly higher for 4R than 9H (83.5% vs. 68.8%, P < 0.001). Drug toxicity leading to treatment noncompletion was low in both groups (1.5% in 4R and 0.7% in 9H, P = 0.23), and no patient progressed to active tuberculosis in either cohort. The 9H cohort was more likely to fail treatment completion because of barriers potentially related to the longer duration of treatment such as relocation or loss to follow-up. CONCLUSIONS: Pediatric patients were significantly more likely to complete LTBI treatment using a 4R than with a 9-month isoniazid regimen. Better completion rates of 4R may increase efficacy of tuberculosis prevention and decrease demand on public health resources.

Increasing Hepatitis B Vaccine Prevalence Among Refugee Children Arriving in the United States, 2006-2012.

OBJECTIVES: To determine whether the addition of hepatitis B virus (HBV) vaccine to national immunization programs improved vaccination rates among refugee children, a marginalized population with limited access to care. METHODS: The sample included 2291 refugees younger than 19 years who completed HBV screening after arrival in the United States. Children were categorized by having been born before or after the addition of the 3-dose HBV vaccine to their birth country's national immunization program. The outcome was serological evidence of immunization. RESULTS: The odds of serological evidence of HBV immunization were higher for children born after the addition of HBV vaccine to their birth country's national immunization program (adjusted odds ratio = 2.54; 95% confidence interval = 2.04, 3.15). CONCLUSIONS: National HBV vaccination programs have contributed to the increase in HBV vaccination coverage observed among US-bound refugee children. PUBLIC HEALTH IMPLICATIONS: Ongoing public health surveillance is needed to ensure that vaccine rates are sustained among diverse, conflict-affected, displaced populations.
