Interventions to Increase Cancer Screening Adherence Among Somali Immigrants in the US and Europe: A Systematic Review.

Cancer screening rates among immigrant and refugee populations in high income countries is significantly lower than native born populations. The objective of this study is to systematically review the effectiveness of interventions to improve screening adherence for breast, cervical and colorectal cancer among Somali immigrants. A literature search was conducted for the years 2000-2021 and eight studies met eligibility criteria. The following intervention components were found to increase adherence to cervical cancer screening: home HPV test, educational workshop for women and education for general practitioners. A patient navigator intervention was found to increase screening for breast cancer. Educational workshops motivated or increased knowledge regarding cancer screening for breast, cervical and colorectal cancer. However, most of the studies had limitations due to methodology with potential for introduction of bias. Therefore, future studies comparing effectiveness of specific intervention components to reduce disparities in cancer screening among Somali immigrants and refugees are encouraged.

Cancer incidence in the Somali population of Olmsted County: A Rochester epidemiology project study.

BACKGROUND: Somali immigrants and refugees constitute one of the largest African ethnic groups immigrating to the United States over the past three decades with the majority resettling in the state of Minnesota. Previous studies have documented significant cancer screening disparities between the Somali population and the general population. However, little is known about cancer incidence among Somali groups living in the United States. METHODS: We determined the incidence of 18 types or sites of malignancy using ICD-9 and ICD-10 codes and compared them between Somali and non-Somali populations in Olmsted County, Minnesota utilizing the Rochester Epidemiology Project medical records-linkage infrastructure for the years 2000-2020. Poisson regression models were used to model the rates for each malignancy. RESULTS: There was a higher incidence and relative risk of liver malignancies among the Somali population versus non-Somali population, but lower relative risk and incidence of the following malignancies: breast, cervical, and melanoma. After direct age-sex adjustment to the United States 2000 Census population, liver was the most common cancer in Somali men, while breast cancer was the most common malignancy in women. CONCLUSION: Malignancies related to infectious agents such as viral hepatitis have a higher incidence in the Somali immigrant population of Olmsted County. There is a lower incidence of malignancies related to lifestyle factors in this Somali population. Findings of this study may help inform cancer prevention and screening strategies among Somali communities in the United States.

Disparities Among Limited English Proficient Patients in Colon Cancer Screening with Multi-target DNA Stool Test.

Racial and language minority groups in the U.S. are at a higher risk for morbidity and mortality from colorectal cancer (CRC), partially due to lower screening rates. This is a retrospective cohort study comparing successful multi-target stool DNA test (mt-sDNA) test completion among patients with limited English proficiency (LEP) and English proficient (EP) patients, from 2015 to 2018. Patients with LEP were frequency matched to EP patients by age at a 3:1 ratio. The percentage of mt-sDNA tests without useful results was 53% among patients with LEP compared to 29% among EP patients (p < 0.0001). The median number of days from order placement to test completion was 62.5 among patients with LEP compared to 33 for EP patients (p = 0.003). This study demonstrates a significant disparity in CRC screening completion using the mt-sDNA test among populations with LEP, which may widen existing disparities in CRC mortality.

Hepatitis B Screening of At-Risk Immigrants Seen at Primary Care Clinics: A Quality Improvement Project.

OBJECTIVE: To test an intervention to increase screening for hepatitis B (HBV) in at-risk immigrants in the primary care setting. PATIENTS AND METHODS: From a Mayo Clinic primary care panel, we identified approximately 19,000 immigrant patients from 9 high-risk countries/ethnic groups with intermediate or high prevalences of chronic HBV. Eligible patients with no record of prior HBV testing scheduled for primary care visits within the study period spanning October 1, 2017, through October 31, 2018, were identified. During the intervention period, the primary health care professional was notified by email 1 week prior to each primary care visit and encouraged to discuss screening for HBV infection and order screening tests at the appointment. We assessed rates of HBV screening during control and intervention periods. RESULTS: We identified 597 patients in the control period and 212 patients in the intervention period who had not been screened previously for HBV. During the intervention period, 31.4% (58) of the 185 eligible patients were screened for HBV vs 7.2% (43) of the 597 eligible patients in the control period. Thus, the intervention resulted in a 4.3-fold increase in screening (P<.00001). Of the 101 patients screened in the at-risk population, 22 (21.8%) screened positive for prior exposure to HBV (hepatitis B core antibody-positive) and 6 (5.9%) for chronic HBV infection (hepatitis B surface antigen-positive). CONCLUSION: Notifying primary care physicians of the high-risk status of immigrant patients substantially increased screening for HBV. Identifying patients with HBV is important for monitoring disease prevalence, preventing transmission, and initiating treatment and cancer surveillance, allowing earlier recognition and prevention of chronic hepatitis, disease reactivation, cirrhosis, and hepatocellular carcinoma.

Closing the Gap: Participatory Formative Evaluation to Reduce Cancer Screening Disparities among Patients with Limited English Proficiency.

Patients with limited English proficiency (LEP) have disproportionately lower rates of cancer screening than English-proficient patients. Given the multifactorial nature of screening disparities, strategies to improve screening rates must address barriers within and outside of the clinic setting. The objectives of this study were to understand local barriers from multiple stakeholder perspectives, to identify potential multilevel intervention approaches, and to mobilize community-engaged intervention decision making and planning. This participatory formative evaluation approach employed needs assessment and user engagement in order to enhance intervention usefulness and relevance. The study took place in several stages and involved clinic and community partners in a small metropolitan area of the Midwest USA. Interviews were conducted with LEP patients (n = 9) who had not completed three recommended screenings (breast, cervical, and colorectal), primary care providers (n = 5), medical interpreter (n = 5), and community members (n = 3). These highlighted multilevel barriers including limited patient understanding of preventive health, time and cost constraints, and variable roles of language interpreters. The literature was also reviewed to identify interventions used with similar populations. Findings from this review suggest that interventions are largely focused on single population groups or address single screening barriers. Finally, a community-academic summit (n = 48 participants) was held to review results and develop recommendations for community and clinic interventions. Findings from this study indicate that it is possible to engage a diverse group of stakeholders in strategies that are responsive to health care providers and patients, including LEP patients from heterogeneous backgrounds.

Understanding User Acceptance of Clinical Decision Support Systems to Promote Increased Cancer Screening Rates in a Primary Care Practice.

OBJECTIVE: Clinical decision support systems (CDDSs) in the electronic medical record (EMR) have been implemented in primary care settings to identify patients due for cancer screening tests, while functioning as a real time reminder system. There is little known about primary care providers (PCPs) perspective or user acceptance of CDSS. The purpose of this study was to investigate primary care provider perceptions of utilizing CDSS alerts in the EMR to promote increased screening rates for breast cancer, cervical cancer, and colorectal cancer. METHODS: An electronic survey was administered to PCPs in a Midwest Health Institution community internal medicine practice from September 25, 2019 through November 27, 2019. RESULTS: Among 37 participants (9 NP/Pas and 28 MD/DOs), the NP/PA group was more likely to agree that alerts were helpful (50%; P-value = .0335) and the number of alerts (89%; P = .0227) in the EMR was appropriate. The NP/PA group also was more likely to find alerts straightforward to use (78%, P = .0239). Both groups agreed about feeling comfortable using the health maintenance alerts (MD/DO = 79%; NP/PA = 100%). CONCLUSION: CDSSs can promote and facilitate ordering of cancer screening tests. The use of technology can promptly identify patients due for a test and act as a reminder to the PCP. PCPs identify these alerts to be a beneficial tool in the EMR when they do not interrupt workflow and provide value to patient care. More work is needed to identify factors that could optimize alerts to be even more helpful, particularly to MD/DO groups.

Healthy Immigrant Families: Randomized Controlled Trial of a Family-Based Nutrition and Physical Activity Intervention.

PURPOSE: To evaluate a healthy eating and physical activity intervention for immigrant families, derived through community-based participatory research. DESIGN: The Healthy Immigrant Families study was a randomized controlled trial with delayed intervention control group, with families as the randomization unit. SETTING: US Midwest city. PARTICIPANTS: Participants were recruited by community partners from Hispanic, Somali, and Sudanese immigrant communities. INTERVENTION: Family health promoters from participating communities delivered 6 healthy eating modules, 4 physical activity modules, and 2 modules synthesizing information in 12 home visits (60-90 minutes) within the first 6 months. Up to 12 follow-up phone calls to each participant occurred within the second 6 months. MEASURES: Primary measures were dietary quality measured with weekday 24-hour recall and reported as Healthy Eating Index score (0-100) and physical activity measured with accelerometers (14 wear days) at baseline, 6, 12, and 24 months. RESULTS: In total, 151 persons (81 adolescents and 70 adults; 44 families) were randomly assigned. At 12 months, significant improvement occurred in Healthy Eating Index scores for adults in the intervention group compared with controls (change, +8.6 vs -4.4; P < .01) and persisted at 24 months (+7.4 from baseline; P < .01). No differences were observed for adolescents and no significant differences occurred between groups for physical activity. CONCLUSION: This intervention produced sustained dietary quality improvement among adults but not among adolescents. Program outcomes are relevant to communities working to decrease cardiovascular risk among immigrant populations.

Healthy immigrant families: Participatory development and baseline characteristics of a community-based physical activity and nutrition intervention.

BACKGROUND: US immigrants often have escalating cardiovascular risk. Barriers to optimal physical activity and diet have a significant role in this risk accumulation. METHODS: We developed a physical activity and nutrition intervention with immigrant and refugee families through a community-based participatory research approach. Work groups of community members and health scientists developed an intervention manual with 12 content modules that were based on social-learning theory. Family health promoters from the participating communities (Hispanic, Somali, Sudanese) were trained to deliver the intervention through 12 home visits during the first 6 months and up to 12 phone calls during the second 6 months. The intervention was tested through a randomized community-based trial with a delayed-intervention control group, with measurements at baseline, 6, 12, and 24 months. Primary measurements included accelerometer-based assessment of physical activity and 24-hour dietary recall. Secondary measures included biometrics and theory-based instruments. RESULTS: One hundred fifty-one individuals (81 adolescents, 70 adults; 44 families) were randomized. At baseline, mean (SD) time spent in moderate-to-vigorous physical activity was 64.7 (30.2) minutes/day for adolescents and 43.1 (35.4) minutes/day for adults. Moderate dietary quality was observed in both age groups. Biometric measures showed that 45.7% of adolescents and 80.0% of adults were overweight or obese. Moderate levels of self-efficacy and social support were reported for physical activity and nutrition. DISCUSSION: Processes and products from this program are relevant to other communities aiming to reduce cardiovascular risk and negative health behaviors among immigrants and refugees. TRIAL REGISTRATION: This trial was registered at Clinicaltrials.gov (NCT01952808).
