    Impacto de la COVID-19 en la mortalidad en Perú mediante la triangulación de múltiples fuentes de datos
    (Pan American Health Organization, 2022) William Valdez Huarcaya; Jorge Antonio Miranda Monzón; Edwin Omar Napanga Saldaña; Cynthia R. Driver
    An analytic cross-sectional study was conducted to quantify the impact of COVID-19 on mortality in Peru. Total excess mortality due to natural and external causes was calculated. The direct and indirect impact of COVID-19 was estimated at two points: when COVID-19 deaths were confirmed by a laboratory test and when they were confirmed by broader criteria (reclassified deaths). This comparison was made in general and by sex, age, and geographical location. The sensitivity of laboratory testing and of death certificates as criteria for confirmation of a COVID-19 death was calculated using reclassified deaths as the gold standard.From epidemiological week (EW) 10 of 2020 to EW 23 of 2021, 349 756 deaths occurred, for an excess of 183 237 deaths, mainly due to natural causes. A total of 100 955 deaths corresponded to deaths confirmed by laboratory tests; however, the reclassification criterion brought this figure to 188 708. Laboratory tests had 53.3% sensitivity; this was lower at the onset of the pandemic (10.6%) and during the first wave (37.8%). The sensitivity of death certificates was higher than laboratory tests (41.7% vs 23.9%) only during the months when little testing was available. These data showed that the impact of COVID-19 on mortality in Peru was mainly direct. Also, in periods with limited access to laboratory testing, death certificates were a useful source for determining deaths directly caused by COVID-19.

    Resultados preliminares del fortalecimiento del sistema informático nacional de defunciones

    Peru has a low coverage of deaths with a cause of death (54%) and a poor-quality registration of causes of death, as about 30% of causes of death are classified as poorly-defined or not very useful for the formulation of public policies. In response to these problems, the Ministry of Health, together with other government agencies, with the support of the Bloomberg Philanthropies "Data for Health Initiative," is implementing the National Death Registry Information System (SINADEF). The objective of this article is to describe the process of strengthening the mortality information system in Peru, focused on the implementation of SINADEF. The activities that have been carried out are described in the following areas: a) Management of the mortality information system, b) Process standardization, c) Use of information and communication technology, d) Coverage of deaths with medical certificate, e) Improvement of the quality of information, f) Development of studies, and g) Monitoring of processes. Since the implementation of SINADEF in August 2016 until July 2018, 28,407 users of the SINADEF application have been created and a total of 122,411 deaths have been registered. The quality of data recording, including the cause of death, has been improved, while low coverage of deaths with a cause of death still persists.
