The epidemiology of sepsis in paediatric intensive care units in Brazil (the Sepsis PREvalence Assessment Database in Pediatric population, SPREAD PED): an observational study.

BACKGROUND: Data on the prevalence and mortality of paediatric sepsis in resource-poor settings are scarce. We aimed to assess the prevalence and in-hospital mortality of severe sepsis and septic shock treated in paediatric intensive care units (PICUs) in Brazil, and risk factors for mortality. METHODS: We performed a nationwide, 1-day, prospective point prevalence study with follow-up of patients with severe sepsis and septic shock, using a stratified random sample of all PICUs in Brazil. Patients were enrolled at each participating PICU on a single day between March 25 and 29, 2019. All patients occupying a bed at the PICU on the study day (either admitted previously or on that day) were included if they were aged 28 days to 18 years and met the criteria for severe sepsis or septic shock at any time during hospitalisation. Patients were followed up until hospital discharge or death, censored at 60 days. Risk factors for mortality were assessed using a Poisson regression model. We used prevalence to generate national estimates. FINDINGS: Of 241 PICUs invited to participate, 144 PICUs (capacity of 1242 beds) included patients in the study. On the day of the study, 1122 children were admitted to the participating PICUs, of whom 280 met the criteria for severe sepsis or septic shock during hospitalisation, resulting in a prevalence of 25·0% (95% CI 21·6-28·8), with a mortality rate of 19·8% (15·4-25·2; 50 of 252 patients with complete clinical data). Increased risk of mortality was associated with higher Pediatric Sequential Organ Failure Assessment score (relative risk per point increase 1·21, 95% CI 1·14-1·29, p<0·0001), unknown vaccination status (2·57, 1·26-5·24; p=0·011), incomplete vaccination status (2·16, 1·19-3·92; p=0·012), health care-associated infection (2·12, 1·23-3·64, p=0·0073), and compliance with antibiotics (2·38, 1·46-3·86, p=0·0007). The estimated incidence of PICU-treated sepsis was 74·6 cases per 100 000 paediatric population (95% CI 61·5-90·5), which translates to 42 374 cases per year (34 940-51 443) in Brazil, with an estimated mortality of 8305 (6848-10 083). INTERPRETATION: In this representative sample of PICUs in a middle-income country, the prevalences of severe sepsis or septic shock and in-hospital mortality were high. Modifiable factors, such as incomplete vaccination and health care-associated infections, were associated with greater risk of in-hospital mortality.

Multisystem Inflammatory Syndrome Associated With Coronavirus Disease in Children: A Multi-centered Study in Belém, Pará, Brazil.

We described the characteristics of 11 children with pediatric multisystem inflammatory syndrome-temporally associated with SARS-CoV-2. The main clinical indications for hospital admission were vasogenic toxic shock (n = 2), Kawasaki disease (n = 4), and Kawasaki disease shock syndrome (n = 5). The echocardiography findings were abnormal in 63% of cases. All patients had 2 or more organ dysfunctions, and the mortality rate was 18%.

Early fluid overload was associated with prolonged mechanical ventilation and more aggressive parameters in critically ill paediatric patients.

AIM: We evaluated the influence of early fluid overload on critically ill children admitted to a paediatric intensive care unit by examining mechanical ventilation (MV), mortality, length of stay and renal replacement therapy. METHODS: This retrospective cohort study covered January 2015 to December 2016 and focused on all episodes of MV support that exceeded 24 hours. The fluid overload percentage (FO%) was calculated daily for the first 72 hours and we estimated its effect on outcomes. RESULTS: We included 186 MV episodes in 154 patients. The median age was 13.8 months, with an interquartile range (IQR) of 3.8-34.0 months, and the mortality rate was 12.4%. The median FO% in the first 72 hours was 8.0% (IQR 3.6%-11.2%). An FO% of ≥10% was associated with higher ventilatory parameters, namely peak inspiratory pressure (P = .023) and positive end expiratory pressure (P = .003), and renal replacement therapy (P = .02) and higher mortality (8.8% vs 19.7%). In a multivariate Cox regression model, FO ≥ 10% at 72 hours was independently associated with longer MV support, but not mortality (P = .001). CONCLUSION: In a heterogeneous paediatric population given MV, an early cumulative FO of ≥10% was associated with more aggressive ventilatory parameters and prolonged length of MV, but not mortality.

Vancomycin-associated Nephrotoxicity and Risk Factors in Critically Ill Children Without Preexisting Renal Injury.

BACKGROUND: A recent systematic review concluded that critically ill pediatric patients have higher odds of vancomycin-related nephrotoxicity [odds ratio (OR): 3.61, 95% CI: 1.21-10.74]. We aimed to assess the incidence and risk factors for vancomycin-associated nephrotoxicity in critically ill children without preexisting renal injury. METHODS: A cohort of children admitted to a pediatric intensive care unit, from 2011 to 2016 treated with vancomycin without preexisting renal injury. The main diagnosis, therapeutic interventions and medications administered in this period were evaluated. Generalized estimating equation models were used to assess the association between clinical covariates and the dependent variable pediatric risk, injury, failure, loss, end-stage renal disease (pRIFLE). RESULTS: Hundred ten patients, representing 1177 vancomycin days, were analyzed. Vancomycin-associated nephrotoxicity was seen in 11.8%. In a multivariate model, higher vancomycin doses were not associated with poorer renal function (P = 0.08). Higher serum vancomycin levels were weakly associated with pRIFLE classification (OR: 1.05, 95% CI: 1.02-1.07). Furosemide or amphotericin B in addition to the vancomycin treatment was associated with impaired renal function (OR: 2.56, 95% CI: 1.38-4.8 and OR: 7.7 95% CI: 2.55-23, respectively). CONCLUSIONS: Vancomycin-associated nephrotoxicity in acute ill children without preexisting renal injury, measured with pRIFLE, is close to 11.8%. Furosemide and amphotericin B in addition to the vancomycin treatment are strong predictors of worse pRIFLE scores. The influence of acute kidney injury status at pediatric intensive care unit admission and the method used for renal function assessment might influence the incidence of vancomycin-associated nephrotoxicity and its associated risk factors.

Nurses' participation in the end-of-life process in two paediatric intensive care units in Brazil.

The aim of this study was to evaluate the medical and nursing care provided to children in the last 24 hours of life in two Brazilian paediatric intensive care units and analyse the nurses' participation in the decision-making process for life support limitation (LSL). The study was based on an analysis of the patients' medical charts, looking at the medical and nursing care provided in the last 24 hours of life during a 6-month period in the two units, and on semi-structured interviews with 20 nurses to evaluate their participation in LSL decisions. The children were classified into two groups: those who were to receive full cardiopulmonary resuscitation (CPR) and a non-CPR group. A total of 34 deaths occurred during the study period. Of these, 17 (50%) were children that had been in the non-CPR group; there were only 10 recorded LSL plans in their medical charts. In the interviews, only 30% of the nurses mentioned active participation in LSL decisions. In conclusion, the paediatric intensive care nurses in these two Brazilian units did not participate much in LSL decisions, and the care offered in the last hours of life to children with terminal and irreversible illness was not primarily directed toward comfort and alleviating suffering.
