This report investigates the impact of potential misclassification of samples on HIV prevalence estimates for 23 surveys conducted from 2010-2014. In addition to visual inspection of laboratory results, we examined how accounting for potential misclassification of HIV status through Bayesian latent ...class models affected the prevalence estimates. Two types of Bayesian models were specified: a model that only uses the individual dichotomous test results and a continuous model that uses the quantitative information of the EIA (i.e., the signal-to-cutoff values). Overall, we found that adjusted prevalence estimates matched the surveys’ original results, with overlapping uncertainty intervals. This suggested that misclassification of HIV status should not affect the prevalence estimates in most surveys. However, our analyses suggested that two surveys may be problematic. The prevalence could have been overestimated in the Uganda AIDS Indicator Survey 2011 and the Zambia Demographic and Health Survey 2013-14, although the magnitude of overestimation remains difficult to ascertain. Interpreting results from the Uganda survey is difficult because of the lack of internal quality control and potential violation of the multivariate normality assumption of the continuous Bayesian latent class model. In conclusion, despite the limitations of our latent class models, our analyses suggest that prevalence estimates from most of the surveys reviewed are not affected by sample misclassification.

Round 3: Key informant findings from 129 countries, territories and areas - Quarter 4 2021
Countries reported disruptions in all health-care settings. In more than half of countries surveyed, many people are still unable to access care at the primary care and community care levels. Significant dis...ruptions have also been reported in emergency care, particularly concerning given the impact on people with urgent health needs. Thirty-six per cent of countries reported disruptions to ambulance services; 32% to 24-hour emergency room services; and 23% to emergency surgeries.
Elective surgeries have also been disrupted in 59% of countries, which can have accumulating consequences on health and well-being as the pandemic continues. Disruptions to rehabilitative care and palliative care were also reported in around half of the countries surveyed.
Major barriers to health service recovery include pre-existing health systems issues which have been exacerbated by the pandemic as well as decreased demand for care.
