J Acquir Immune Defic Syndr 2023 94 (4) 301-307 BACKGROUND: The US President's Emergency Plan for AIDS Relief (PEPFAR) aims to address the higher risk of cervical cancer among women living with HIV (WLHIV) by offering high quality screening services in the highest burden regions of the world. METHODS: We analyzed PEPFAR Monitoring, Evaluation, and Reporting data from CDC-supported sites in 13 countries in sub-Saharan Africa for WHLIV aged 15+ years who accessed cervical cancer screening services (mostly visual inspection, with ablative or excisional treatment offered for precancerous lesions), April 2018-March 2022. We calculated the positivity by age, country, and clinical visit type (first lifetime screen, or routine rescreening). We fitted negative binomial random-coefficient models of log-linear trends in time to estimate the probabilities of testing positive, and any temporal trends in positivity. RESULTS: Among the 2.8 million completed cancer screens, 5.4% identified precancerous lesions, and 0.8% were positive for suspected invasive cervical cancers (6.1% overall). The positivity rates declined over the study period among those women screening for cervical cancer for the first time, and among those women presenting to antiretroviral therapy (ART) clinics for routine rescreening. CONCLUSIONS: These positivity rates are lower than expectations set by the published literature. Further research is needed to determine if these lower rates are attributable to the high level of consistent ART use among these populations, and systematic program monitoring and quality assurance activities are essential to ensure WLHIV have access to the highest possible quality prevention services. |

Clin Infect Dis 2019 69 S302-s310 BACKGROUND: Minimally invasive tissue sampling (MITS) is a simplified postmortem examination technique that has shown to be an adequate approach for cause of death investigation in low-resource settings. It requires relatively low level of infrastructures and can be performed by health professionals with no background in pathology. A training program has been developed for the Child Health and Mortality Prevention Surveillance (CHAMPS) network to guarantee standardization of specimen collection techniques, procedures, and laboratory methods. METHODS: The training program has included assessment of the site capacities and training on a standardized protocol of MITS sampling and histological processing. The project has also introduced a program of training for trainers for the personnel from Mozambique. To guarantee the adequacy of the procedure in each site, a trainer accompanied the local teams when the activities started. Training outcomes were assessed by evaluating the quality of the samples obtained and the quality of the slides produced locally. RESULTS: Between June 2016 and October 2018, the laboratories of 7 sites (Bangladesh, Ethiopia, Kenya, Mali, Mozambique, Sierra Leone, and South Africa) have been evaluated and upgraded. Training has been delivered to 63 staff members from all sites. More than 600 MITS procedures have been performed. The quantity of tissue obtained in the MITS by the local teams was sufficient or abundant in 73%, and 87% of the slides were considered as technically acceptable or excellent. CONCLUSIONS: Satisfactory standardization of MITS and histology procedures has been achieved across all CHAMPS sites through organized capacity-building plans. |
