RESUMO

BACKGROUND: There remain key knowledge gaps regarding HIV testing needs and priorities among refugee youth in low and middle-income country (LMIC) humanitarian settings. The HIV prevention cascade framework focuses on three domains (motivation, access, effective use) central to prevention uptake, yet is understudied in relationship to HIV testing, particularly among refugee youth. Uganda is an exemplar context to explore refugee youth HIV testing needs and priorities as it hosts 1.5 million refugees and is Africa's largest refugee hosting nation. In this study, we explored perceptions and experiences regarding HIV testing among refugee youth living in Bidi Bidi refugee settlement, Uganda. METHODS: We conducted a community-based research study in Bidi Bidi Refugee Settlement, one of the world's largest refugee settlements with over 195,000 residents. This qualitative study involved four focus groups (2 with young women, 2 with young men) with refugee youth aged 16-24 living in Bidi Bidi refugee settlement. We applied thematic analysis informed by the HIV prevention cascade to understand domains of motivation, access, and effective use that emerged as salient for HIV testing engagement. RESULTS: Participants (n = 40; mean age: 20 years, standard deviation: 2.2) included refugee young women (n = 20) and young men (n = 20), of whom 88% had a lifetime HIV test and 58% had ever heard of HIV self-testing. Participant discussions described HIV testing motivation was influenced by dimensions of: HIV treatment and testing knowledge; risk perception; positive and negative consequences of use; and social norms regarding gender and age. Access to HIV testing was shaped by: limited availability; distance and language barriers; confidentiality concerns; and affordability. Effective use of and engagement with HIV testing was related to HIV serostatus knowledge self-efficacy and in/equitable partner dynamics. CONCLUSIONS: Complex, multi-level factors shape motivation for, access to, and effective use of HIV testing among refugee youth in Bidi Bidi. Findings align with the HIV prevention cascade framework that helps to identify gaps to inform intervention development with youth in humanitarian settings. HIV testing approaches tailored for refugee youth in contexts such as Bidi Bidi can foster HIV prevention and treatment literacy, gender equity, gender-based violence prevention, and intersectional stigma reduction.

RESUMO

PURPOSE: The Ugandan Ministry of Health adopted BI-RADS as standard of care in 2016. The authors performed a medical audit of breast ultrasound practices at four tertiary-level hospitals to assess interpretive performance. The authors also determined the effect of a low-cost navigation program linking breast imaging and pathology on the percentage of patients completing diagnostic care. METHODS: The authors retrieved 966 consecutive diagnostic breast ultrasound reports, with complete data, for studies performed on women aged >18 years presenting with symptoms of breast cancer between 2018 and 2020 from participating hospitals. Ultrasound results were linked to tumor registries and patient follow-up. A medical audit was performed according to the ACR's BI-RADS Atlas, fifth edition, and results were compared with those of a prior audit performed in 2013. At Mulago Hospital, an intervention was piloted on the basis of patient navigation, cost sharing, and same-day imaging, tissue sampling, and pathology. RESULTS: In total, 888 breast ultrasound examinations (91.9%) were eligible for inclusion. Compared with 2013, the postintervention cancer detection rate increased from 38 to 148.7 cancers per 1,000 examinations, positive predictive value 2 from 29.6% to 48.9%, and positive predictive value 3 from 62.7% to 79.9%. Specificity decreased from 90.5% to 87.7% and sensitivity from 92.3% to 81.1%. The mean time from tissue sampling to receipt of a diagnosis decreased from 60 to 7 days. The intervention increased the percentage of patients completing diagnostic care from 0% to 100%. CONCLUSIONS: Efforts to establish a culture of continuous quality improvement in breast ultrasound require robust data collection that links imaging results to pathology and patient follow-up. Interpretive performance met BI-RADS benchmarks for palpable masses, except sensitivity. This resource-appropriate strategy linking imaging, tissue sampling, and pathology interpretation decreased time to diagnosis and rates of loss to follow-up and improved the precision of the audit.

RESUMO

BACKGROUND: Greater than 80% of women presenting for breast cancer treatment in Uganda have late-stage disease, which is attributable to a dysfunctional referral system and a lack of recognition of the early signs and symptoms among primary health care providers, and compounded by the poor infrastructure and inadequate human capacity. Improving the breast health care system requires a systemic approach beginning with situational analysis to identify systematic gaps that prevent sustainable improvements in outcome. METHODS: The authors performed a situational analysis of the breast health care system using methods developed by the Breast Health Global Initiative. Based on their findings, they developed a series of recommendations for strengthening the health system for the early diagnosis of breast cancer based on clinical detection, referral, tissue sampling, and diagnosis. RESULTS: Deficits in the recognition of breast cancer signs and symptoms, the underuse of clinical breast examination as a diagnostic and/or screening tool, the centralization of diagnostic tests (radiology and pathology), reliance on excisional biopsies rather than needle biopsies, and a lack of trained professionals and knowledge of the referral system all contribute to significant health system delays. CONCLUSIONS: To strengthen referral networks and improve the early diagnosis of breast cancer in Uganda, national referral hospitals should provide educational programs to primary health care providers in community health centers (CHCs), at which the majority of women first present with symptoms. At secondary district-level facilities in which imaging and tissue sampling can be performed, the capacity for diagnostic testing could be increased through task shifting of basic interpretation (abnormal vs normal) from specialists to nonspecialists using networking technology to facilitate remote oversight from specialists at the national referral hospitals.

RESUMO

BACKGROUND: Mammography, the gold standard for breast cancer screening misses some cancers, especially in women with dense breasts. Breast ultrasonography as a supplementary imaging tool for further evaluation of symptomatic women with mammographically dense breasts may improve the detection of mass lesions otherwise missed at mammography. The purpose of this study was to determine the incremental breast cancer detection rate using US scanning in symptomatic women with mammographically dense breasts in a resource poor environment. METHODS: A cross sectional descriptive study. Women referred for mammography underwent bilateral breast ultrasound, and mammography for symptom evaluation. The lesions seen by both modalities were described using sonographic BI-RADS lexicon and categorized. Ultrasound guided core biopsies were performed. IRB approval was obtained and all participants provided informed written consent. RESULTS: In total 148 women with mammographically dense breasts were recruited over six months. The prevalence of breast cancer in symptomatic women with mammographically dense breasts was 22/148 (15%). Mammography detected 16/22 (73%) of these cases and missed 6/22 (27%). The six breast cancer cases missed were correctly diagnosed on breast ultrasonography. Sonographic features typical of breast malignancy were irregular shape, non-parallel orientation, non circumscribed margin, echogenic halo, and increased lesion vascularity (p values < 0.005). Typical sonofeatures of benign mass lesions were: oval shape, parallel orientation and circumscribed margin (p values <0.005). CONCLUSION: Breast ultrasound scan as a supplementary imaging tool detected 27% more malignant mass lesions otherwise missed by mammography among these symptomatic women with mammographically dense breasts. We recommend that ultra sound scanning in routine evaluation of symptomatic women with mammographically dense breasts.
