Incremento de infecciones respiratorias agudas graves en niños durante la última etapa de la pandemia COVID-19 / Increase in severe acute respiratory infections in children during the last phase of the COVID-19 pandemic

Objetivo. La pandemia COVID-19 ha causado una variación en la circulación de otros patógenos respiratorios. Nuestro objetivo fue analizar la epidemiología de las infecciones respiratorias agudas graves (IRAG) en niños durante 3 años de pandemia COVID-19, en comparación con un período previo de la misma dimensión temporal. Pacientes y métodos. Estudio observacional, realizado en un hospital terciario de España, que analizó la frecuencia y características de pacientes ingresados por IRAG en la Unidad de Cuidados Intensivos Pediátricos (UCIP) durante la pandemia COVID-19 (1 marzo-2020 a 28 de febrero-2023), en relación a un período pre-pandemia (1 marzo-2017 a 29 febrero-2020). Resultados. Se incluyeron 268 pacientes (59,6% varones). La mediana de edad fue 9,6 meses (RIQ 1,7 – 37). En el período pre-pandemia hubo 126 ingresos con una media de 42 admisiones/año. Durante la pandemia se produjeron 142 ingresos, observándose una reducción significativa de admisiones en el primer año (12 ingresos/año), en contraste con 82 ingresos durante el tercer año, que representó un incremento del 95% respecto a la media de admisiones/año en pre-pandemia. Además, en el último año se evidenció un incremento de coinfecciones virales en relación al período prepandemia (54,9% vs 39,7%; p=0,032). No hubo diferencias en días de hospitalización, ni estancia en UCIP. Conclusiones. Durante el último año, coincidiendo con bajas tasas de hospitalización por COVID en España, observamos un notable incremento de ingresos en la UCIP por IRAG por otras causas. Probablemente, el período prolongado de baja exposición a patógenos por las medidas adoptadas durante la pandemia, ha provocado una disminución de la inmunidad poblacional con un repunte de infecciones respiratorias.

Objective. The COVID-19 pandemic has caused a variation in the circulation of respiratory pathogens. Our aim was to analyze the epidemiology of severe acute respiratory infections (SARI) in children during 3 years of the COVID-19 pandemic, in comparison with a previous period. Patients and Methods. An observational study was conducted in a tertiary hospital in Spain, which analyzed the frequency and characteristics of patients admitted for SARI in the Pediatric Intensive Care Unit (PICU) during the COVID-19 pandemic (1 March 2020 to 28 February 2023), compared to pre-pandemic period (1 March 2017 to 29 February 2020). Results. A total of 268 patients were included (59.6% males). The median age was 9.6 months (IQR 1.7 – 37). In the pre-pandemic period, there were 126 admissions with an average of 42 admissions/year. During the pandemic, there were 142 admissions, observing a significant reduction in admissions in the first year (12 admissions/year), in contrast to 82 admissions during the third year, which represented an increase of 95% compared to the average of admissions/year in pre-pandemic. In addition, in the last year there was evidence of an increase in viral coinfections in relation to pre-pandemic period (54.9% vs 39.7%; p=0.032). There were no differences in length of hospital stay or PICU stay. Conclusions. During the last year, coinciding with low rates of hospitalization for COVID in Spain, we observed a notable increase in admissions to the PICU for SARI. Probably, the prolonged period of low exposure to pathogens due to the measures adopted during the pandemic might have caused a decrease in population immunity with a rise in severe respiratory infections.

How Do Children Die in PICUs Nowadays? A Multicenter Study From Spain.

OBJECTIVES: To describe how children currently die in Spanish PICUs, their epidemiologic characteristics and clinical diagnoses. DESIGN: Prospective multicenter observational study. SETTING: Eighteen PICUs participating in the MOdos de Morir en UCI Pediátrica-2 (MOMUCI-2) study in Spain. PATIENTS: Children 1 to 16 years old who died in PICU during 2017 and 2018. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: During the 2-year study period, 250 deaths were recorded. Seventy-three children (29.3%) were younger than 1 year, 131 (52.6%) were between 1 and 12 years old, and 45 (18.1%) were older than 12. One-hundred eighty patients (72%) suffered from an underlying chronic disease, 54 (21.6%) had been admitted to PICU in the past 6 months, and 71 (28.4%) were severely disabled upon admission. Deaths occurred more frequently on the afternoon-night shift (62%) after a median PICU length of stay of 3 days (1-12 d). Nearly half of the patients died (48.8%) after life-sustaining treatment limitation, 71 died (28.4%) despite receiving life-sustaining therapies and cardiopulmonary resuscitation, and 57 (22.8%) were declared brain dead. The most frequent type of life-sustaining treatment limitation was the withdrawal of mechanical ventilation (20.8%), followed by noninitiation of cardiopulmonary resuscitation (18%) and withdrawal of vasoactive drugs (13.7%). Life-sustaining treatment limitation was significantly more frequent in patients with an underlying neurologic-neuromuscular disease, respiratory disease as the cause of admission, a previous admission to PICU in the past 6 months, and severe disability. Multivariate analyses indicated that life-sustaining treatment limitation, chronicity, and poor Pediatric Cerebral Performance Category score were closely related. CONCLUSIONS: Currently, nearly half of the deaths in Spanish PICUs occur after the withdrawal of life-sustaining treatments. These children are more likely to have had previous admissions to the PICU, be severely disabled or to suffer from chronic diseases. Healthcare professionals who treat critically ill children ought to be aware of this situation and should therefore be prepared and trained to provide the best end-of-life care possible.
