Comparing standard versus enhanced implementation of an evidence-based HIV prevention program among Bahamian sixth grade students: findings from nationwide implementation trials.

BACKGROUND: Effective implementation strategies are needed to address the challenges encountered by teachers in implementation of evidence-based HV prevention programs in schools. The current study: 1) compares implementation fidelity of Focus on Youth in the Caribbean (FOYC) plus Caribbean Informed Parents and Children Together (CImPACT) intervention using enhanced implementation strategies (including biweekly monitoring/feedback and site-based mentoring) to those using more traditional approach (teacher training only); and 2) evaluates the impact of school coordinators' and mentors' performance on teachers' implementation fidelity and student outcomes. METHODS: Data from an enhanced implementation trial in 2019-2020, involving 24 government primary schools, 79 teachers, and 2252 students, were compared to data from a standard implementation trial in 2011-2012, involving 35 government primary schools, 110 teachers and 2811 students using mixed-effects modeling and structural equation modeling. FINDINGS: Teachers in the 2019-2020 trial taught more core activities (28.3 vs. 16.3, t = 10.80, P < 0.001) and sessions (7.2 vs. 4.4, t = 9.14, P < 0.001) than those participating in the 2011-2012 trial. Teachers taught > 80% of the intervention curriculum in 2019-2020 compared to 50% curriculum delivery in 2011-2012. Teachers who had a "very good" or "excellent" school coordinator in their schools taught more core activities than those who had a "satisfactory" school coordinator (30.4 vs. 29.6 vs. 22.3, F = 18.54, P < 0.001). Teachers who worked in a school which had a "very good" mentor, taught more core activities than those teachers who did not have a mentor or had only a "satisfactory" mentor (30.4 vs. 27.6; t = 2.96; p = 0.004). Teachers' confidence in implementing core activities, comfort level with the curriculum, attitudes towards sex education in schools, and perceived principal support were significantly related to increased self-efficacy, which in turn was related to teachers' implementation fidelity. The degree of implementation was significantly associated with improved student outcomes. IMPLICATIONS/CONCLUSION: An evidence-based HIV prevention intervention can achieve a high degree of implementation when delivered with enhanced implementation strategies and implementation monitoring. Future program implementers should consider the purposeful selection and training of school coordinators and mentors to support low-implementing teachers as a potentially important strategy when attempting to achieve high-quality implementation of school-based interventions.

Investigating a key structural determinant of health, racism, and related social determinants of health in Massachusetts during the COVID-19 pandemic.

A disproportionate burden of the ongoing COVID-19 pandemic is being shouldered by members of racial and ethnic minorities and socially disadvantaged communities. Structural and social determinants of health have been recognized as key contributors to the inequalities observed. Racism, a major structural determinant of health that patterns related social determinants of health, in the USA, warrants further investigation. In this perspective piece we provide an overview of the historical context of racism, followed by preliminary findings from the ongoing COVIDStory study-a cross-sectional study addressing perceptions of COVID-19 and COVID-19 research-that highlights the experiences of non-Hispanic Black and Hispanic identifying adult participants, residing in Worcester Massachusetts, during the COVID-19 pandemic. We then discuss these findings in the context of current and past research considering racism and relevant social determinants of health. Our study results suggest that racism and its residuals (residential segregation, economic insecurity, discrimination, bias, and vigilance) are modern challenges for non-Hispanic Black and Hispanic participants, and these findings are supported by the existing literature. It is our hope that this perspective piece provides additional evidence for action on structural and social determinants affecting the health of minoritized people, especially those living in Massachusetts.

The HIV continuum of care in the Bahamas in 2014 / El proceso continuo de atención de la infección por el VIH en las Bahamas en el 2014

ABSTRACT Objective The HIV cascade of care describes the spectrum of engagement in HIV care from diagnosis to viral suppression (VS). The study objective was to develop a baseline HIV cascade of care for new HIV diagnoses in the Bahamas in 2014. Methods Individuals who were newly diagnosed with HIV in 2014 and known to be alive within a year of that diagnosis were included in the cascade of care (n = 250). Individuals with one CD4 or HIV viral load (VL) measure in 2014 were considered linked to care. Those with at least two CD4 counts in the year were considered retained in care. Eligibility for antiretroviral therapy (ART) was based on having a CD4 count < 350 cells/mm3. ART adherence was defined as filled prescriptions > 11 months/year. VL < 1 000 copies/ml was considered suppressed. Comparisons were made in the cascades by gender and age. Results Of the 250 persons in the study, 79 of them (32%) were retained in care. Antiretrovirals (ARVs) were prescribed to 116 of the 250 (46%); of those 116, 48 of them (41%) achieved VS. A higher proportion of women achieved VS than did men, but this difference did not reach statistical significance. Similarly, there were differences in VS based on age, but the differences were not statistically significant. Conclusions In the Bahamas, increased efforts are needed to help people living with HIV to link to and be retained in care. VS may remain suboptimal unless ART is scaled up and adherence interventions are included in measures to improve the treatment cascade.

RESUMEN Objetivo El proceso continuo de la atención de la infección por el VIH describe el espectro de intervenciones en la atención de la infección, desde el diagnóstico hasta la supresión viral. El objetivo del estudio fue elaborar un proceso continuo de la atención como punto de referencia y comparación para nuevos diagnósticos de infección por el VIH en las Bahamas en el 2014. Métodos En el proceso continuo de la atención se incluyó a personas con diagnóstico de infección por el VIH en el 2014 y que continuaban vivas a un año del diagnóstico (n = 250). Se consideró vinculadas a la atención a aquellas personas con un recuento de linfocitos CD4 o una medición de la carga viral de VIH en el 2014. Aquellas con al menos dos recuentos de CD4 en el año se consideraron retenidas en la atención. La aptitud para el tratamiento antirretroviral se basó en tener un recuento de CD4 < 350 células/mm3. Se definió adherencia al tratamiento antirretroviral como la entrega de la prescripción >11 meses/año. Se consideró supresión viral a una carga viral de < 1 000 copias/ml. Se hicieron comparaciones en las cascadas por sexo y edad. Resultados De las 250 personas que participaron en el estudio, 79 (32%) se retuvieron en la atención. Se prescribieron antirretrovirales a 116 de las 250 personas (46%); de estas 116 personas, 48 (41%) lograron la supresión viral. Las mujeres lograron la supresión viral en una proporción mayor que los hombres, pero esta diferencia no fue estadísticamente significativa. Igualmente, se observaron diferencias en la supresión viral según la edad, pero estas tampoco fueron estadísticamente significativas. Conclusiones En las Bahamas, es necesario incrementar los esfuerzos para ayudar a las personas con infección por el VIH a vincularse y mantenerse en la atención. La supresión viral puede permanecer en niveles subóptimos a menos que se amplíe el tratamiento antirretroviral y se incluyan intervenciones de adherencia terapéutica en las medidas para mejorar el proceso continuo de la atención.
