ABSTRACT
OBJECTIVE: To investigate excess mortality during the COVID-19 pandemic and its spatial distribution in Pernambuco, Brazil. METHODS: This was an ecological, descriptive and analytical study of deaths, by municipality, recorded on the Mortality Information System, in 2020 and 2021. Excess mortality was measured by comparing observed and expected deaths, the latter estimated by calculating standardized mortality ratio (SMR). SMR and respective confidence intervals (95%CI) were calculated. Spatial analysis was performed by calculating the Global and Local Moran Index. RESULTS: Excess mortality was 20.6% and 27.5%, respectively, in 2020 and 2021, with positive spatial correlation (p-value < 0.05). More populous municipalities (2020: SMR = 1.26; 95%CI 1.24;1.27 and 2021: SMR = 1.34; 95%CI 1.32;1.34), more developed municipalities (2020: SMR = 1.43; 95%CI 1.41;1.44 and 2021: SMR = 1.51;95%CI 1.50;1.53) and municipalities in the Sertão region (2020:SMR = 1.31;95%CI 1.30;1.33 and 2021: SMR = 1.44; 95%CI 1.42;1.46) showed greater excess deaths. CONCLUSION: Excess mortality coincided with peak periods of COVID-19 transmission.

RESUMEN Objetivo Investigar el exceso de mortalidad durante la pandemia de Covid-19 y su distribución espacial en Pernambuco. Métodos Estudio ecológico, descriptivo y analítico de las defunciones, por municipio, registradas en el Sistema de Información de Mortalidad, en 2020 y 2021. El exceso de mortalidad se midió comparando las defunciones observadas y esperadas, estimada por tasas de mortalidad estandarizadas. Se calcularon la SMR y los respectivos intervalos de confianza (IC95%). El análisis espacial se realizó mediante el cálculo del Índice de Moran Global y Local. Resultados Hubo un exceso de mortalidad del 20,6% y 27,5%, respectivamente, en 2020 y 2021, y una correlación espacial positiva (valor p < 0,05). Municipios más poblados (2020: SMR = 1,26; IC95%: 1,24;1,27 y 2021: SMR = 1,34; IC95%: 1,32;1,34), más desarrollados (2020: SMR = 1,43; IC95%: 1,41;1,44 y 2021: SMR = 1,51; IC95%: 1,50;1,53) y Sertão (2020:SMR = 1,31;IC95%: 1,30;1,33 y 2021: SMR = 1,44; IC95%: 1,42;1,46) presentaron mayor exceso fallecidos. Conclusión El exceso de mortalidad coincidió con períodos pico de transmisión de Covid-19.
RESUMO Objetivo Investigar o excesso de mortalidade na pandemia de covid-19 e sua distribuição espacial no estado de Pernambuco. Métodos Estudo ecológico, descritivo e analítico dos óbitos, por município, registrados no Sistema de Informação sobre Mortalidade, em 2020 e 2021. O excesso de mortalidade foi mensurado comparando-se os óbitos observados e esperados, este último estimado pelo cálculo das taxas de mortalidade padronizadas. Foram calculados a standardized mortality ratio (SMR) e os respectivos intervalos de confiança (IC95%). A análise espacial foi realizada pelo cálculo do Índice de Moran Global e Local. Resultados Verificou-se excesso de mortalidade de 20,6% e de 27,5%, respectivamente, em 2020 e 2021, e correlação espacial positiva (p-valor < 0,05). Municípios mais populosos (2020: SMR = 1,26; IC95% 1,24;1,27 e 2021: SMR = 1,34; IC95% 1,32;1,34), mais desenvolvidos (2020: SMR = 1,43; IC95% 1,41;1,44 e 2021: SMR = 1,51; IC95% 1,50;1,53) e do Sertão (2020: SMR = 1,31; IC95% 1,30;1,33 e 2021: SMR = 1,44; IC95% 1,42;1,46) apresentaram maior excesso de mortes. Conclusão O excesso de mortalidade coincidiu com os períodos de pico de transmissão da covid-19.
