Acceptance towards COVID-19 vaccination in Latin America and the Caribbean: A systematic review and meta-analysis.

INTRODUCTION: Vaccination represents an important strategy to mitigate COVID-19 related morbidity and mortality by protecting against severe forms of the disease and reducing hospitalization and death rates. In this sense, the objective of this study is to estimate the prevalence of Vaccination Intention (VI) against COVID-19 in Latin America and Caribbean (LAC). METHODS: We conducted a systematic review with a comprehensive search strategy for the following databases: PubMed, Scopus and Web of Science. A random-effect model meta-analysis was carried out using observational studies assessing the intention to vaccines against COVID-19 in LAC countries. The Clopper-Pearson method was used to estimate 95% Confidence Intervals. The quality assessment was developed using the Newcastle-Ottawa Scale adapted for cross-sectional studies. A subgroup analysis by study location and a sensitivity analysis were developed. RESULTS: Nineteen cross-sectional studies were included. Five meta-analyzes were performed according to the target population of the included studies. The VI in the general population of LAC was 78.0% (95%CI: 74.0%-82.0%). The VI for non-pregnant women was 78.0% (95%CI: 58.0%-99.0%), for elderly population was 63.0% (95%CI: 59.0%-69.0%), for pregnant women was 69.0% (95%CI: 61.0%-76.0%) and for health-personnel was 83.0% (95% CI: 71.0%-96.0%). The sensitivity analysis for general population meta-analysis that included only low risk of bias studies showed a 77.0% VI (95%CI: 73.0%-82.0%) and for non-pregnant women, 85.0% VI (95%CI: 79.0%-90.0%). CONCLUSION: Despite the high prevalence of VI in general population found in our study, VI prevalence from elderly people and pregnant women are lower than other population groups and overall population.

Prevalencia y factores asociados al ingreso a la unidad de cuidados intensivos en niños hospitalizados por neumonía adquirida en la comunidad / Prevalence and factors associated with admission to the intensive care unit in children hospitalized for community-acquired pneumonia

RESUMEN Objetivo. Determinar la prevalencia y los factores asociados al ingreso a la unidad de cuidados intensivos en niños y adolescentes con neumonía adquirida en la comunidad. Materiales y métodos. Estudio observacional transversal analítico en el Instituto Nacional de Salud del Niño San Borja en el 2019, la muestra estuvo conformada por niños de mayores de un mes y menores de 18 años que ingresaron a emergencia con diagnóstico de neumonía adquirida en la comunidad. Se utilizó la regresión de Poisson para evaluar asociación. Resultados. Se evaluaron 166 pacientes con diagnóstico de neumonía, 94 (56,6%) fueron varones y la mediana de la edad fue 24 meses (RIC: 11‒48). La mayoría de los pacientes presentó un puntaje PIRO modificado leve de 136 (81,9%), 31 (18,7%) pacientes tuvieron neumonía complicada y 24 (14,5%) ingresaron a cuidados intensivos. A mayor edad se halló menor prevalencia de ingreso a UCI (RP=0,99, IC95%: 0,98‒0,99); la gravedad evaluada con el score PIRO modificado (RP=3,40, IC95%: 1,46‒7,93) y la presencia de neumonía complicada (RP: 5,88, IC95%: 2,46‒14,06) estuvieron asociados al ingreso a cuidados intensivos. Conclusiones. En niños con neumonía adquirida en la comunidad la prevalencia de ingreso a cuidados intensivos fue de 14,5%. Los pacientes con neumonía de menor edad, con mayor gravedad evaluada con el puntaje PIRO modificado y con neumonía complicada tienen mayor prevalencia de ingreso a cuidados intensivos.

ABSTRACT Objective. To determine the prevalence and factors associated with intensive care unit admission in children and adolescents with community-acquired pneumonia. Materials and methods. Analytical cross-sectional observational study at the Instituto Nacional de Salud del Niño San Borja in 2019. The sample consisted of children older than one month and younger than 18 years who were admitted to emergency diagnosed with community-acquired pneumonia. We used Poisson regression to assess association. Results. We evaluated 166 patients diagnosed with pneumonia, 94 (56.6%) were male and the median age was 24 months (IQR: 11 - 48). Most patients had a mild modified PIRO score of 136 (81.9%); 31 (18.7%) patients had complicated pneumonia and 24 (14.5%) were admitted to intensive care. The higher the age, the lower the prevalence of admission to ICU (PR=0.99, 95%CI: 0.98-0.99). The severity assessed with the modified PIRO score (PR=3.40, 95%CI: 1.46-7.93) and the presence of complicated pneumonia (PR: 5.88, 95%CI: 2.46-14.06) were associated with admission to intensive care. Conclusions. The prevalence of admission to intensive care in children with community-acquired pneumonia was 14.5%. Younger patients with pneumonia, with greater severity assessed with the modified PIRO score and with complicated pneumonia have a higher prevalence of admission to intensive care.
