Eleven years impact of a stepwise educational program on healthcare associated infections and antibiotics consumption in an intensive care unit of a tertiary hospital in Brazil.

BACKGROUND: Hospital acquired infections (HAI) and liberal use of broad-spectrum antibiotics are common in intensive care unit(ICU)s of low-middle income countries. We investigated the long-term association of a stepwise multifaceted educational program with the incidence of HAIs and antibiotics use in a Brazilian ICU. We also evaluated the program's cost impact. METHODS: We retrieved data from a prospective daily collected database of a twelve bedrooms ICU, all admitted patients within a period of eleven years were enrolled. FINDINGS: From 03/15/2007 to 09/11/2019, we admitted 3059 patients where 2406 (79%) survived the ICU stay. Median age was 51 years-old, and median SAPS3 was 53. The initial density of catheter related blood infection (4.3 events / 1000 patients-day), urinary tract infection (9.2 event / 1000 patients-day) and ventilator associated pneumonia (54.9 events / 1000 patients-day) felt during the observed period to (0.35 events / 1000 patients-day), (0 events / 1000 patients-day), and (1.5 events / 1000 patients-day) respectively. The days of antibiotic therapy also decreased from 797.9 days of therapy / 1000 patients day to 292.3 days of therapy / 1000 patients day. The total cost per patient also decreased. The adjusted mortality rate was steady during the studied period from 23.2% to 22.9%. INTERPRETATION: A stepwise multifaceted educational program is an effective way to reduce hospital-associated infections, improve the rational use of antibiotics, and reduce costs. This impact occurred in a long term, and is probably consistent.

Alternative approaches to analyzing ventilator-free days, mortality and duration of ventilation in critical care research / Abordagens alternativas para analisar dias livres de ventilador, mortalidade e duração da ventilação em estudos de cuidados intensivos

ABSTRACT Objective: To discuss the strengths and limitations of ventilator-free days and to provide a comprehensive discussion of the different analytic methods for analyzing and interpreting this outcome. Methods: Using simulations, the power of different analytical methods was assessed, namely: quantile (median) regression, cumulative logistic regression, generalized pairwise comparison, conditional approach and truncated approach. Overall, 3,000 simulations of a two-arm trial with n = 300 per arm were computed using a two-sided alternative hypothesis and a type I error rate of α = 0.05. Results: When considering power, median regression did not perform well in studies where the treatment effect was mainly driven by mortality. Median regression performed better in situations with a weak effect on mortality but a strong effect on duration, duration only, and moderate mortality and duration. Cumulative logistic regression was found to produce similar power to the Wilcoxon rank-sum test across all scenarios, being the best strategy for the scenarios of moderate mortality and duration, weak mortality and strong duration, and duration only. Conclusion: In this study, we describe the relative power of new methods for analyzing ventilator-free days in critical care research. Our data provide validation and guidance for the use of the cumulative logistic model, median regression, generalized pairwise comparisons, and the conditional and truncated approach in specific scenarios.

RESUMO Objetivo: Discutir os pontos fortes e as limitações dos dias livres de ventilador e fornecer uma discussão abrangente dos diferentes métodos analíticos para analisar e interpretar esse desfecho. Métodos: Por meio de simulações, avaliou-se o poder de diferentes métodos analíticos, a saber: regressão quantílica (mediana), regressão logística cumulativa, comparação generalizada entre pares, abordagem condicional e abordagem truncada. No total, foram computadas 3.000 simulações de um estudo de dois braços com n = 300 por braço, usando uma hipótese alternativa bilateral e uma taxa de erro tipo I de α = 0,05. Resultados: Ao considerar o poder, a regressão mediana não teve bom desempenho em estudos em que o efeito do tratamento foi impulsionado principalmente pela mortalidade. A regressão mediana teve desempenho melhor em situações com efeito fraco na mortalidade, mas forte na duração, somente na duração e na mortalidade e duração moderadas. Verificou-se que a regressão logística cumulativa produziu um poder semelhante ao do teste de soma de postos de Wilcoxon em todos os cenários, sendo a melhor estratégia nos cenários de mortalidade e duração moderadas, mortalidade fraca e duração forte, e apenas duração. Conclusão: Neste estudo, descrevemos o poder relativo de novos métodos para analisar os dias livres de ventilador em estudos de cuidados intensivos. Nossos dados fornecem validação e orientação quanto ao uso do modelo logístico cumulativo, regressão mediana, comparações generalizadas entre pares e a abordagem condicional e truncada em cenários específicos.

Delirium severity and outcomes of critically ill COVID-19 patients / Gravidade do delirium e desfechos de pacientes críticos com COVID-19

ABSTRACT Objective: To investigate the impact of delirium severity in critically ill COVID-19 patients and its association with outcomes. Methods: This prospective cohort study was performed in two tertiary intensive care units in Rio de Janeiro, Brazil. COVID-19 patients were evaluated daily during the first 7 days of intensive care unit stay using the Richmond Agitation Sedation Scale, Confusion Assessment Method for Intensive Care Unit (CAM-ICU) and Confusion Method Assessment for Intensive Care Unit-7 (CAM-ICU-7). Delirium severity was correlated with outcomes and one-year mortality. Results: Among the 277 COVID-19 patients included, delirium occurred in 101 (36.5%) during the first 7 days of intensive care unit stay, and it was associated with a higher length of intensive care unit stay in days (IQR 13 [7 - 25] versus 6 [4 - 12]; p < 0.001), higher hospital mortality (25.74% versus 5.11%; p < 0.001) and additional higher one-year mortality (5.3% versus 0.6%, p < 0.001). Delirium was classified by CAM-ICU-7 in terms of severity, and higher scores were associated with higher in-hospital mortality (17.86% versus 34.38% versus 38.46%, 95%CI, p value < 0.001). Severe delirium was associated with a higher risk of progression to coma (OR 7.1; 95%CI 1.9 - 31.0; p = 0.005) and to mechanical ventilation (OR 11.09; 95%CI 2.8 - 58.5; p = 0.002) in the multivariate analysis, adjusted by severity and frailty. Conclusion: In patients admitted with COVID-19 in the intensive care unit, delirium was an independent risk factor for the worst prognosis, including mortality. The delirium severity assessed by the CAM-ICU-7 during the first week in the intensive care unit was associated with poor outcomes, including progression to coma and to mechanical ventilation.

RESUMO Objetivo: Investigar como a gravidade do delirium afeta pacientes graves com COVID-19 e sua associação com os desfechos. Métodos: Estudo de coorte prospectivo realizado em duas unidades de terapia intensiva terciárias no Rio de Janeiro (RJ). Os pacientes com COVID-19 foram avaliados diariamente durante os primeiros 7 dias de internação na unidade de terapia intensiva usando a escala de agitação e sedação de Richmond, a Confusion Assessment Method for Intensive Care Unit (CAM-ICU) e a Confusion Assessment Method for Intensive Care Unit-7 (CAM-ICU-7). A gravidade do delirium foi correlacionada com os desfechos e a mortalidade em 1 ano. Resultados: Entre os 277 pacientes com COVID-19 incluídos, o delirium ocorreu em 101 (36,5%) durante os primeiros 7 dias de internação na unidade de terapia intensiva e foi associado a maior tempo de internação na unidade de terapia intensiva em dias (IQ: 13 [7 - 25] versus 6 [4 - 12]; p < 0,001), maior mortalidade hospitalar (25,74% versus 5,11%; p < 0,001) e maior mortalidade em 1 ano (5,3% versus 0,6%, p < 0,001). O delirium foi classificado pela CAM-ICU-7 em termos de gravidade, e escores maiores foram associados à maior mortalidade hospitalar (17,86% versus 34,38% versus 38,46%, IC95%, valor de p < 0,001). O delirium grave foi associado a um risco maior de progressão ao coma (RC de 7,1; IC95% 1,9 - 31,0; p = 0,005) e à ventilação mecânica (RC de 11,09; IC95% 2,8 - 58,5; p = 0,002) na análise multivariada, ajustada por gravidade e fragilidade Conclusão: Em pacientes internados com COVID-19 na unidade de terapia intensiva, o delirium foi fator de risco independente para o pior prognóstico, incluindo mortalidade. A gravidade do delirium avaliada pela CAM-ICU-7 durante a primeira semana na unidade de terapia intensiva foi associada a desfechos desfavoráveis, incluindo a progressão ao coma e à ventilação mecânica.

Dapagliflozin in patients with critical illness: rationale and design of the DEFENDER study / Dapagliflozina em pacientes com doença crítica: justificativa e desenho do estudo DEFENDER

ABSTRACT Background: Critical illness is a major ongoing health care burden worldwide and is associated with high mortality rates. Sodium-glucose cotransporter-2 inhibitors have consistently shown benefits in cardiovascular and renal outcomes. The effects of sodium-glucose cotransporter-2 inhibitors in acute illness have not been properly investigated. Methods: DEFENDER is an investigator-initiated, multicenter, randomized, open-label trial designed to evaluate the efficacy and safety of dapagliflozin in 500 adult participants with acute organ dysfunction who are hospitalized in the intensive care unit. Eligible participants will be randomized 1:1 to receive dapagliflozin 10mg plus standard of care for up to 14 days or standard of care alone. The primary outcome is a hierarchical composite of hospital mortality, initiation of kidney replacement therapy, and intensive care unit length of stay, up to 28 days. Safety will be strictly monitored throughout the study. Conclusion: DEFENDER is the first study designed to investigate the use of a sodium-glucose cotransporter-2 inhibitor in general intensive care unit patients with acute organ dysfunction. It will provide relevant information on the use of drugs of this promising class in critically ill patients. ClinicalTrials.gov registry: NCT05558098

The risks of the new morbidities acquired during pediatric onco-critical care and their life-shortening effects.

OBJECTIVE: The authors investigated the functional status at ICU admission and at hospital discharge, and the impact of dysfunctions on survivors' lifespan. METHOD: Single-center retrospective cohort. The FSS (Functional Status Scale) was calculated at ICU admission and at hospital discharge. A new morbidity was defined as an increase in FSS ≥ 3. RESULTS: Among 1002 patients, there were 855 survivors. Of these, 194 (22.6%) had died by the end of the study; 45 (5.3%) had a new morbidity. Means in the motor domain at admission and discharge were 1.37 (SD: 0.82) and 1.53 (SD 0.95, p = 0.002). In the feeding domain, the means were 1.19 (SD 0.63) and 1.30 (SD 0.76), p = 0.002; global means were 6.93 (SD 2.45) and 7.2 (SD 2.94), p = 0.007.  Acute respiratory failure requiring mechanical ventilation, the score PRISM IV, age < 5 years, and central nervous system tumors were independent predictors of new morbidity. New morbidity correlated with lower odds of survival after hospital discharge, considering all causes of death (p = 0.014), and was independently predictive of death (Cox hazard ratio = 1.98). In Weibull models, shortening in the life span of 14.2% (p = 0.014) was estimated as a new morbidity. CONCLUSIONS: New morbidities are related to age, disease severity at admission, and SNC tumors. New morbidities, in turn, correlate with lower probabilities of survival and shortening of the remaining life span. Physical rehabilitation interventions in this population of children may have the potential to provide an increase in lifespan.

[Correlation between the shock index and the anaerobic index]. / Correlación entre el índice de choque y el índice anaerobio.

Background: Shock is defined as an acute circulatory insufficiency that causes cellular dysfunction. The shock index (SI) and the anaerobic index or the relationship between the veno-arterial gradient of carbon dioxide and the difference between the arterial and venous content of O2 [∆P(v-a)CO2/ΔC(a-v)O2] are markers of systemic hypoperfusion. Objective: To determine if there is a correlation between the SI and the anaerobic index in patients with circulatory shock. Material and methods: Observational and prospective study in patients with circulatory shock. The SI and the anaerobic index were calculated at admission to the intensive care unit (ICU) and during their stay. Pearson's correlation coefficient was calculated and the association of SI with mortality was explored with bivariate logistic regression. Results: 59 patients aged 55.5 (± 16.5) years, 54.3% men, were analyzed. The most frequent type of shock was hypovolemic (40.7%). They had SOFA score: 8.4 (± 3.2) and APACHE II: 18.5 (± 6). The SI was: 0.93 (± 0.32) and the anaerobic index: 2.3 (± 1.3). Global correlation was r = 0.15; at admission r = 0.29; after 6 hours: r = 0.19; after 24 hours: r = 0.18; after 48 hours: r = 0.44, and after 72 hours: r = 0.66. The SI > 1 at ICU admission had an OR 3.8 (95% CI: 1.31-11.02), p = 0.01. Conclusions: The SI and the anaerobic index have a weak positive correlation during the first 48 hours of circulatory shock. The SI > 1 is a possible risk factor for death in patients with circulatory shock.

Introducción: el choque se define como una insuficiencia circulatoria aguda que ocasiona disfunción celular. El índice de choque (ICh) y el índice anaerobio o relación entre el gradiente veno-arterial de dióxido de carbono y la diferencia entre el contenido arterial y venoso de O2 [∆P(v-a)CO2/ΔC(a-v)O2] son marcadores de hipoperfusión sistémica. Objetivo: determinar si existe correlación entre el ICh y el índice anaerobio en pacientes con choque circulatorio. Material y métodos: estudio observacional y prospectivo en pacientes con choque circulatorio. Se calcularon el ICh y el índice anaerobio al ingreso a la unidad de cuidados intensivos (UCI) y durante su estancia. Se calculó el coeficiente de correlación de Pearson y se exploró la asociación del ICh con la mortalidad con una regresión logística bivariada. Resultados: se analizaron 59 pacientes de 55.5 (± 16.5) años, 54.3% hombres. El tipo de choque más frecuente fue el hipovolémico (40.7%). Tuvieron puntaje SOFA: 8.4 (± 3.2) y APACHE II: 18.5 (± 6). El ICh fue: 0.93 (± 0.32) y el índice anaerobio: 2.3 (± 1.3). La correlación global fue r = 0.15; al ingreso: r = 0.29; a las 6 horas: r = 0.19; a las 24 horas: r = 0.18; a las 48 horas: r = 0.44, y a las 72 horas: r = 0.66. El ICh > 1 al ingreso a la UCI tuvo una RM 3.8 (IC 95%: 1.31-11.02), p = 0.01. Conclusiones: el ICh y el índice anaerobio tienen una correlación positiva débil durante las primeras 48 horas del choque circulatorio. El ICh > 1 es un posible factor de riesgo de muerte en pacientes con choque circulatorio.

Association of appropriateness for ICU admission with resource use, organ support and long-term survival in critically ill cancer patients.

We aimed to evaluate the characteristics, resource use and outcomes of critically ill patients with cancer according to appropriateness of ICU admission. This was a retrospective cohort study of patients with cancer admitted to ICU from January 2017 to December 2018. Patients were classified as appropriate, potentially inappropriate, or inappropriate for ICU admission according to the Society of Critical Care Medicine guidelines. The primary outcome was ICU length of stay (LOS). Secondary outcomes were one-year, ICU, and hospital mortality, hospital LOS and utilization of ICU organ support. We used logistic regression and competing risk models accounting for relevant confounders in primary outcome analyses. From 6700 admitted patients, 5803 (86.6%) were classified as appropriate, 683 (10.2%) as potentially inappropriate and 214 (3.2%) as inappropriate for ICU admission. Potentially inappropriate and inappropriate ICU admissions had lower likelihood of being discharged from the ICU than patients with appropriate ICU admission (sHR 0.55, 95% CI 0.49-0.61 and sHR 0.65, 95% CI 0.53-0.81, respectively), and were associated with higher 1-year mortality (OR 6.39, 95% CI 5.60-7.29 and OR 11.12, 95% CI 8.33-14.83, respectively). Among patients with appropriate, potentially inappropriate, and inappropriate ICU admissions, ICU mortality was 4.8%, 32.6% and 35.0%, and in-hospital mortality was 12.2%, 71.6% and 81.3%, respectively (p < 0.01). Use of organ support was more common and longer among patients with potentially inappropriate ICU admission. The findings of our study suggest that inappropriateness for ICU admission among patients with cancer was associated with higher resource use in ICU and higher one-year mortality among ICU survivors.

Association between acute disease severity and one-year quality of life among post-hospitalisation COVID-19 patients: Coalition VII prospective cohort study.

PURPOSE: To assess the association between acute disease severity and 1-year quality of life in patients discharged after hospitalisation due to coronavirus disease 2019 (COVID-19). METHODS: We conducted a prospective cohort study nested in 5 randomised clinical trials between March 2020 and March 2022 at 84 sites in Brazil. Adult post-hospitalisation COVID-19 patients were followed for 1 year. The primary outcome was the utility score of EuroQol five-dimension three-level (EQ-5D-3L). Secondary outcomes included all-cause mortality, major cardiovascular events, and new disabilities in instrumental activities of daily living. Adjusted generalised estimating equations were used to assess the association between outcomes and acute disease severity according to the highest level on a modified ordinal scale during hospital stay (2: no oxygen therapy; 3: oxygen by mask or nasal prongs; 4: high-flow nasal cannula oxygen therapy or non-invasive ventilation; 5: mechanical ventilation). RESULTS: 1508 COVID-19 survivors were enrolled. Primary outcome data were available for 1156 participants. At 1 year, compared with severity score 2, severity score 5 was associated with lower EQ-5D-3L utility scores (0.7 vs 0.84; adjusted difference, - 0.1 [95% CI - 0.15 to - 0.06]); and worse results for all-cause mortality (7.9% vs 1.2%; adjusted difference, 7.1% [95% CI 2.5%-11.8%]), major cardiovascular events (5.6% vs 2.3%; adjusted difference, 2.6% [95% CI 0.6%-4.6%]), and new disabilities (40.4% vs 23.5%; adjusted difference, 15.5% [95% CI 8.5%-22.5]). Severity scores 3 and 4 did not differ consistently from score 2. CONCLUSIONS: COVID-19 patients who needed mechanical ventilation during hospitalisation have lower 1-year quality of life than COVID-19 patients who did not need mechanical ventilation during hospitalisation.

Group Concept Mapping Conceptualizes High-Quality Care for Long-Stay Pediatric Intensive Care Unit Patients and Families.

OBJECTIVE: To describe and conceptualize high-quality care for long-stay pediatric intensive care unit (PICU) patients using group concept mapping (GCM). STUDY DESIGN: We convened an expert panel to elucidate domains of high-quality care for this growing patient population for which transitory care models fail to meet their needs. Thirty-one healthcare professionals and 7 parents of patients with previous prolonged PICU hospitalizations comprised a diverse, interprofessional multidisciplinary panel. Participants completed the prompt "For PICU patients and families experiencing prolonged lengths of stay, high quality care from the medical team includes ______", with unlimited free text responses. Responses were synthesized into individual statements, then panelists sorted them by idea similarity and rated them by perceived importance. Statement analysis using GCM software through GroupWisdom generated nonoverlapping clusters representing domains of high-quality care. RESULTS: Participants submitted 265 prompt responses representing 313 unique ideas, resulting in 78 final statements for sorting and rating. The resultant cluster map best representing the data contained 8 domains: (1) Family-Centered Care and Shared Decision Making, (2) Humanizing the Patient, (3) Clinician Supports and Resources, (4) Multidisciplinary Coordination of Care, (5) Family Well-Being, (6) Anticipatory Guidance and Care Planning, (7) Communication, and (8) Continuity of Care. CONCLUSIONS: GCM empowered a panel of healthcare professionals and parents to explicitly describe and conceptualize high-quality care for patients and families experiencing prolonged PICU stays. This information will aid the effort to address shortcomings of transitory PICU care models.

Clinical characteristics and outcomes of patients with COVID-19 admitted to the intensive care unit during the first and second waves of the pandemic in Brazil: a single-center retrospective cohort study

ABSTRACT Objective To describe and compare the clinical characteristics and outcomes of patients admitted to intensive care units during the first and second waves of the COVID-19 pandemic. Methods In this retrospective single-center cohort study, data were retrieved from the Epimed Monitor System; all adult patients admitted to the intensive care unit between March 4, 2020, and October 1, 2021, were included in the study. We compared the clinical characteristics and outcomes of patients admitted to the intensive care unit of a quaternary private hospital in São Paulo, Brazil, during the first (May 1, 2020, to August 31, 2020) and second (March 1, 2021, to June 30, 2021) waves of the COVID-19 pandemic. Results In total, 1,427 patients with COVID-19 were admitted to the intensive care unit during the first (421 patients) and second (1,006 patients) waves. Compared with the first wave group [median (IQR)], the second wave group was younger [57 (46-70) versus 67 (52-80) years; p<0.001], had a lower SAPS 3 Score [45 (42-52) versus 49 (43-57); p<0.001], lower SOFA Score on intensive care unit admission [3 (1-6) versus 4 (2-6); p=0.018], lower Charlson Comorbidity Index [0 (0-1) versus 1 (0-2); p<0.001], and were less frequently frail (10.4% versus 18.1%; p<0.001). The second wave group used more noninvasive ventilation (81.3% versus 53.4%; p<0.001) and high-flow nasal cannula (63.2% versus 23.0%; p<0.001) during their intensive care unit stay. The intensive care unit (11.3% versus 10.5%; p=0.696) and in-hospital mortality (12.3% versus 12.1%; p=0.998) rates did not differ between both waves. Conclusion In the first and second waves, patients with severe COVID-19 exhibited similar mortality rates and need for invasive organ support, despite the second wave group being younger and less severely ill at the time of intensive care unit admission.

Ninety-day outcomes in patients diagnosed with COVID-19 in São Paulo, Brazil: a cohort study / Desfechos em 90 dias entre pacientes com diagnóstico de COVID-19 em São Paulo (SP): estudo de coorte

ABSTRACT Objective: COVID-19 has been associated with a significant burden to those who survive the acute phase. We aimed to describe the quality of life and symptoms of anxiety, depression, and posttraumatic stress disorder (PTSD) at 90 days after hospital discharge of COVID-19 patients. Methods: Patients with COVID-19 admitted to a private hospital in the city of São Paulo, Brazil, between April of 2020 and April of 2021 were interviewed by telephone at 30 and 90 days after discharge to assess the quality of life and symptoms of depression, anxiety, and PTSD. Results: A total of 2,138 patients were included. The mean age was 58.6 ± 15.8 years, and the median length of hospital stay was 9.0 (5.0-15.8) days. Between the two time points, depression increased from 3.1% to 7.2% (p < 0.001), anxiety increased from 3.2% to 6.2% (p < 0.001), and PTSD increased from 2.3% to 5.0% (p < 0.001). At least one physical symptom related to COVID-19 diagnosis persisted in 32% of patients at day 90. Conclusions: Persistence of physical symptoms was high even at 90 days after discharge. Although the prevalence of symptoms of anxiety, depression, and PTSD was low, these symptoms persisted for three months, with a significant increase between the time points. This finding indicates the need to identify at-risk patients so that they can be given an appropriate referral at discharge.

RESUMO Objetivo: A COVID-19 tem sido associada a um fardo significativo para aqueles que sobrevivem à fase aguda. Nosso objetivo foi descrever a qualidade de vida e sintomas de ansiedade, depressão e transtorno de estresse pós-traumático (TEPT) 90 dias após a alta hospitalar em pacientes com COVID-19. Métodos: Pacientes com COVID-19 internados em um hospital privado na cidade de São Paulo (SP) entre abril de 2020 e abril de 2021 foram entrevistados por telefone 30 e 90 dias após a alta para avaliar a qualidade de vida e sintomas de depressão, ansiedade e TEPT. Resultados: Foram incluídos 2.138 pacientes. A média de idade foi de 58,6 ± 15,8 anos, e a mediana do tempo de internação hospitalar foi de 9,0 (5,0-15,8) dias. Entre os dois momentos, a depressão aumentou de 3,1% para 7,2% (p < 0,001), a ansiedade, de 3,2% para 6,2% (p < 0,001), e o TEPT, de 2,3% para 5,0% (p < 0,001). Pelo menos um sintoma físico relacionado ao diagnóstico de COVID-19 persistia em 32% dos pacientes no 90º dia. Conclusões: A persistência dos sintomas físicos foi elevada mesmo 90 dias após a alta. Embora a prevalência de sintomas de ansiedade, depressão e TEPT tenha sido baixa, esses sintomas persistiram por três meses, com aumento significativo entre os momentos. Esse achado indica a necessidade de identificar os pacientes de risco para que possam receber o encaminhamento adequado no momento da alta.

Biomarkers of neuropsychiatric dysfunction in intensive care unit survivors: a prospective cohort study / Biomarcadores de disfunção neuropsiquiátrica em sobreviventes de unidades de terapia intensiva: um estudo de coorte prospectivo

ABSTRACT Objective: To assess factors associated with long-term neuropsychiatric outcomes, including biomarkers measured after discharge from the intensive care unit. Methods: A prospective cohort study was performed with 65 intensive care unit survivors. The cognitive evaluation was performed through the Mini-Mental State Examination, the symptoms of anxiety and depression were evaluated using the Hospital Anxiety and Depression Scale, and posttraumatic stress disorder was evaluated using the Impact of Event Scale-6. Plasma levels of amyloid-beta (1-42) [Aβ (1-42)], Aβ (1-40), interleukin (IL)-10, IL-6, IL-33, IL-4, IL-5, tumor necrosis factor alpha, C-reactive protein, and brain-derived neurotrophic factor were measured at intensive care unit discharge. Results: Of the variables associated with intensive care, only delirium was independently related to the occurrence of long-term cognitive impairment. In addition, higher levels of IL-10 and IL-6 were associated with cognitive dysfunction. Only IL-6 was independently associated with depression. Mechanical ventilation, IL-33 levels, and C-reactive protein levels were independently associated with anxiety. No variables were independently associated with posttraumatic stress disorder. Conclusion: Cognitive dysfunction, as well as symptoms of depression, anxiety, and posttraumatic stress disorder, are present in patients who survive a critical illness, and some of these outcomes are associated with the levels of inflammatory biomarkers measured at discharge from the intensive care unit.

RESUMO Objetivo: Avaliar os fatores associados aos desfechos neuropsiquiátricos de longo prazo, incluindo biomarcadores, medidos após a alta da unidade de terapia intensiva. Métodos: Foi realizado um estudo de coorte prospectivo com 65 sobreviventes de unidades de terapia intensiva. A avaliação cognitiva foi realizada por meio do Miniexame do Estado Mental; os sintomas de ansiedade e depressão foram avaliados por meio da Escala Hospitalar de Ansiedade e Depressão, e o transtorno de estresse pós-traumático foi avaliado pela Escala de Impacto do Evento-6. Os níveis plasmáticos de beta amiloide (1-42), beta amiloide (1-40), interleucina 10, interleucina 6, interleucina 33, interleucina 4, interleucina 5, fator de necrose tumoral alfa, proteína C-reativa e fator neurotrófico derivado do cérebro foram medidos na alta da unidade de terapia intensiva. Resultados: Das variáveis associadas à terapia intensiva, apenas o delirium foi relacionado de forma independente à ocorrência de comprometimento cognitivo de longo prazo. Além disso, níveis mais altos de interleucina 10 e interleucina 6 foram associados à disfunção cognitiva. Apenas a interleucina 6 foi associada de forma independente à depressão. A ventilação mecânica, os níveis de interleucina 33 e os níveis de proteína C-reativa foram associados de forma independente à ansiedade. Nenhuma variável foi associada de forma independente ao transtorno de estresse pós-traumático. Conclusão: A disfunção cognitiva, bem como os sintomas de depressão, ansiedade e transtorno de estresse pós-traumático, estão presentes em pacientes que sobrevivem a uma doença grave, e alguns desses desfechos estão associados aos níveis de biomarcadores inflamatórios medidos na alta da unidade de terapia intensiva.

Associations of Race With Sedation Depth Among Mechanically Ventilated Adults: A Retrospective Cohort Study.

OBJECTIVES: To evaluate the association of race with proportion of time in deep sedation among mechanically ventilated adults. DESIGN: Retrospective cohort study from October 2017 to December 2019. SETTING: Five hospitals within a single health system. PATIENTS: Adult patients who identified race as Black or White who were mechanically ventilated for greater than or equal to 24 hours in one of 12 medical, surgical, cardiovascular, cardiothoracic, or mixed ICUs. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: The exposure was White compared with Black race. The primary outcome was the proportion of time in deep sedation during the first 48 hours of mechanical ventilation, defined as Richmond Agitation-Sedation Scale values of -3 to -5. For the primary analysis, we performed mixed-effects linear regression models including ICU as a random effect, and adjusting for age, sex, English as preferred language, body mass index, Elixhauser comorbidity index, Laboratory-based Acute Physiology Score, Version 2, ICU admission source, admission for a major surgical procedure, and the presence of septic shock. Of the 3337 included patients, 1242 (37%) identified as Black, 1367 (41%) were female, and 1002 (30%) were admitted to a medical ICU. Black patients spent 48% of the first 48 hours of mechanical ventilation in deep sedation, compared with 43% among White patients in unadjusted analysis. After risk adjustment, Black race was significantly associated with more time in early deep sedation (mean difference, 5%; 95% CI, 2-7%; p < 0.01). CONCLUSIONS: There are disparities in sedation during the first 48 hours of mechanical ventilation between Black and White patients across a diverse set of ICUs. Future work is needed to determine the clinical significance of these findings, given the known poorer outcomes for patients who experience early deep sedation.

O que mudou entre os períodos de pico e de platô durante a primeira onda do SARS-CoV-2? Estudo multicêntrico português em unidades de cuidados intensivos / What changed between the peak and plateau periods of the first COVID-19 pandemic wave? A multicentric Portuguese cohort study in intensive care

RESUMO Objetivo: Analisar e comparar as características de pacientes críticos com a COVID-19, a abordagem clínica e os resultados entre os períodos de pico e de platô na primeira onda pandêmica em Portugal. Métodos: Este foi um estudo de coorte multicêntrico ambispectivo, que incluiu pacientes consecutivos com a forma grave da COVID-19 entre março e agosto de 2020 de 16 unidades de terapia intensiva portuguesas. Definiram-se as semanas 10 - 16 e 17 - 34 como os períodos de pico e platô. Resultados: Incluíram-se 541 pacientes adultos com mediana de idade de 65 [57 - 74] anos, a maioria do sexo masculino (71,2%). Não houve diferenças significativas na mediana de idade (p = 0,3), no Simplified Acute Physiology Score II (40 versus 39; p = 0,8), na pressão parcial de oxigênio/fração inspirada de oxigênio (139 versus 136; p = 0,6), na terapia com antibióticos na admissão (57% versus 64%; p = 0,2) ou na mortalidade aos 28 dias (24,4% versus 22,8%; p = 0,7) entre o período de pico e platô. Durante o período de pico, os pacientes tiveram menos comorbidades (1 [0 - 3] versus 2 [0 - 5]; p = 0,002); fizeram mais uso de vasopressores (47% versus 36%; p < 0,001) e ventilação mecânica invasiva na admissão (58,1% versus 49,2%; p < 0,001), e tiveram mais prescrição de hidroxicloroquina (59% versus 10%; p < 0,001), lopinavir/ritonavir (41% versus 10%; p < 0,001) e posição prona (45% versus 36%; p = 0,04). Entretanto, durante o platô, observou-se maior uso de cânulas nasais de alto fluxo (5% versus 16%; p < 0,001) na admissão, remdesivir (0,3% versus 15%; p < 0,001) e corticosteroides (29% versus 52%; p < 0,001), além de menor tempo de internação na unidade de terapia intensiva (12 versus 8 dias; p < 0,001). Conclusão: Houve mudanças significativas nas comorbidades dos pacientes, nos tratamentos da unidade de terapia intensiva e no tempo de internação entre os períodos de pico e platô na primeira onda da COVID-19.

ABSTRACT Objective: To analyze and compare COVID-19 patient characteristics, clinical management and outcomes between the peak and plateau periods of the first pandemic wave in Portugal. Methods: This was a multicentric ambispective cohort study including consecutive severe COVID-19 patients between March and August 2020 from 16 Portuguese intensive care units. The peak and plateau periods, respectively, weeks 10 - 16 and 17 - 34, were defined. Results: Five hundred forty-one adult patients with a median age of 65 [57 - 74] years, mostly male (71.2%), were included. There were no significant differences in median age (p = 0.3), Simplified Acute Physiology Score II (40 versus 39; p = 0.8), partial arterial oxygen pressure/fraction of inspired oxygen ratio (139 versus 136; p = 0.6), antibiotic therapy (57% versus 64%; p = 0.2) at admission, or 28-day mortality (24.4% versus 22.8%; p = 0.7) between the peak and plateau periods. During the peak period, patients had fewer comorbidities (1 [0 - 3] versus 2 [0 - 5]; p = 0.002) and presented a higher use of vasopressors (47% versus 36%; p < 0.001) and invasive mechanical ventilation (58.1 versus 49.2%; p < 0.001) at admission, prone positioning (45% versus 36%; p = 0.04), and hydroxychloroquine (59% versus 10%; p < 0.001) and lopinavir/ritonavir (41% versus 10%; p < 0.001) prescriptions. However, a greater use of high-flow nasal cannulas (5% versus 16%, p < 0.001) on admission, remdesivir (0.3% versus 15%; p < 0.001) and corticosteroid (29% versus 52%, p < 0.001) therapy, and a shorter ICU length of stay (12 days versus 8, p < 0.001) were observed during the plateau. Conclusion: There were significant changes in patient comorbidities, intensive care unit therapies and length of stay between the peak and plateau periods of the first COVID-19 wave.

RESUMO A infecção pela COVID-19 em sua ampla manifestação de sintomas e comportamento clínico hemodinâmico na paciente grávida mostrou variar em espectro de leve a grave. No presente trabalho relatamos a gestão e abordagem bem sucedida de um paciente de 24 semanas de gestação com insuficiência respiratória tipo I associada à síndrome de desconforto respiratório agudo primário grave (SARS-CoV-2) com fenótipo H de tipo inflamatório com hipoxemia grave e ocupação alveolar dos quatro quadrantes com choque séptico e pneumonia grave devido à SARS-CoV-2 com PCR positiva para COVID-19.

Effect of the Helping Babies Breathe Program on Newborn Outcomes: Systematic Review and Meta-Analysis.

Background and objectives: In low- and middle-income countries, the leading cause of neonatal mortality is perinatal asphyxia. Training in neonatal resuscitation has been shown to decrease this cause of mortality. The program "Helping Babies Breathe" (HBB) is a program to teach basic neonatal resuscitation focused on countries and areas with limited economic resources. The aim of the study was to determine the effect of the implementation of the HBB program on newborn outcomes: mortality and morbidity. Material and Methods: A systematic review was carried out on observational studies and clinical trials that reported the effect of the implementation in low- and middle-income countries of the HBB program on neonatal mortality and morbidity. We carried out a meta-analysis of the extracted data. Random-effect models were used to evaluate heterogeneity, using the Cochrane Q and I2 tests, and stratified analyses were performed by age and type of outcome to determine the sources of heterogeneity. Results: Eleven studies were identified. The implementation of the program includes educational strategies focused on the training of doctors, nurses, midwives, and students of health professions. The poled results showed a decrease in overall mortality (OR 0.67; 95% CI 0.57, 0.80), intrapartum stillbirth mortality (OR 0.62; 95% CI 0.51, 0.75), and first-day mortality (OR 0.70; 95% IC 0.64, 0.77). High heterogeneity was found, which was partly explained by differences in the gestational age of the participants. Conclusions: The implementation of the program HBB in low- and medium-income countries has a significant impact on reducing early neonatal mortality.

[Prevalence of diarrhea in adult patients in intensive care and its relationship with ready-to-use enteral formulas] / Prevalencia de diarrea en pacientes adultos en terapia intensiva y su relación con las fórmulas enterales listas para utilizar

Introduction: Diarrhea is a frequent complication in critically ill patients. Its origin is multifactorial. The objective of this work is to analyze the relationship between 5 ready-to-use formulas and the development of diarrhea in critically ill patients. Methods: Retrospective study where the volume of the stools of 315 patients and the presence of diarrhea defined with a cut-off point of a volume of 250 ml/day were evaluated. 35.34% of the patients presented diarrhea with said cut-off point. The mean volume of stools was 269.20 ml (95% CI: 255.05-283.06). Results: It was observed that all the formulas analyzed had a slight correlation with the Spearman test between the volume provided and the volume of stools, being: Nutricia Nutrison ® (R: 0.159; P: 0.053), Nutricia Multifibra ® (R: 0.296; <0.001), Nutricia Peptisorb ® (R: 0.323; P<0.001), Nutricia Protison ® (R: 0.108; P<0.001), Fresenius Supportan ® (R: 0.152; P<0.001). Multivariate analysis was performed and it was observed that there were no differences in the incidence of diarrhea between the different enteral formulas during the first 10 days. The change of formulas during hospitalization would be a predisposing factor for diarrhea. Conclusion: Therefore, the formula and the volume provided are factors that could influence whether patients have diarrhoea. Understanding these possible influences in a deeper way will allow the safest choice of enteral formulas for a patient with diarrhea.

Introducción: La diarrea es una complicación frecuente en los pacientes críticos. Su origen es multifactorial. El objetivo de este trabajo es analizar la relación entre 5 fórmulas listas para usar y el desarrollo de diarrea en pacientes críticos. Métodos: Estudio retrospectivo donde se evaluó el volumen de las deposiciones de 315 pacientes y la presencia de diarrea definida con un punto de corte con un volumen de 250 ml/día. Resultados: 35.34% de los pacientes presentaron diarrea con dicho punto de corte. El volumen medio de deposiciones fue de 269.20 ml (IC 95%: 255.05-283.06). Se observó que todas las fórmulas analizadas tenían una correlación leve con la prueba de spearman entre el volumen aportado y el volumen de las deposiciones, siendo:  Nutricia Nutrison ® (R: 0.159; P: 0.053), Nutricia Multifibra ® (R: 0.296; <0.001), Nutricia Peptisorb ® (R: 0.323; P<0.001), Nutricia Protison ® (R: 0.108; P<0.001), Fresenius Supportan ® (R: 0.152; P<0.001). Se realizó análisis multivariado y se observó que no hubo diferencias en la incidencia de diarrea entre las distintas fórmulas enterales durante los primeros 10 días. La fibra soluble sería un factor protector en cambio la fibra mixta y semielemental serían factores que aumentan la incidencia de diarrea. Conclusión: Por lo tanto, la fórmula y el volumen aportado son factores que podrían influenciar en que los pacientes tengan diarrea. Entendiendo estas posibles influencias de una manera mas profunda, permitirá elegir las formulas enterales con mas seguridad para un paciente con diarrea.

Scales to measure post intensive care syndrome, a scoping review.

INTRODUCTION: Post Intensive Care Syndrome is a recently studied syndrome that affects between 50% and 70% of patients admitted to the ICU, its detection is complex due to the great variety of affected components. OBJECTIVE: To determine the most widely used assessment instruments for the detection of post-intensive care syndrome, according to the evidence in the last 5 years. METHODOLOGY: A scoping review was carried out in the databases: Academic Search, ScienceDirect, Scielo, Biblioteca Virtual en Salud, Medline, and Springer Link, with terms «Postintensive care syndrome¼ and «Post-intensive care syndrome¼. This review included 22 articles that met the criteria of: research or review typology, English, Spanish or Portuguese language, with access to the full text and published between 2015 and 2020. CONCLUSIONS: Most of the instruments used to measure post-intensive care syndrome are divided according to the components of physical affectation (the Medical Research Council scale, the Katz index and the Barthel index); cognitive (Repeatable Battery for the Assessment of Neuropsychological Status, and the Montreal Cognitive Assessment test); and mental (Hospital Anxiety and Depression Scale, Beck's anxiety test, Depression Inventory Second Edition scale and Post Traumatic Stress Syndrome-14 scale). In addition, two tools were found that measure the event in its entirety with its three components, such as the Healthy Aging Brain Care Monitor and the Post-Intensive Care Syndrome Questionnaire.
