Risk factors and outcomes of ventilator-associated pneumonia in patients with traumatic brain injury: A systematic review and meta-analysis.

BACKGROUND: Ventilator-associated pneumonia (VAP) is a common complication in traumatic brain injury (TBI) patients, which increases morbidity and negatively affects outcomes. Risk factors and outcomes in these patients remain controversial. The aim of the present study is to explore the risk factors and clinical outcomes of patients with VAP and TBI. METHODS: Two researchers conducted independent systematic literature searches of Pubmed, Cochrane Database, Scopus, Medline Ovid, Science Direct databases, published from inception to January 2024. The Newcastle-Ottawa scale was used to assess study quality. A meta-analysis was performed using a random-effects model when heterogeneity I2 > 50 % and a fixed-effects model when I2 < 50 %; in addition, a subgroup analysis was performed to explore VAP risk factors, and publication bias was assessed with the funnel plot and Begg's and Egger's tests. All results were considered statistically significant when p < 0.05. The certainty of the evidence was evaluated using the GRADE (Grading of Recommendations Assessment, Development, and Evaluation) methodology. RESULTS: Twelve studies were included in the meta-analysis with a total of 2883 patients. Male gender [OR 1.58 (95 % CI 1.23, 2.02) p < 0.05 I2 0 %] and abbreviated injury scale (head: H-AIS) [≥ 3 OR 2.79 (95 % CI 1.58, 4.93) p < 0.05 I2 0 %] increased the risk of VAP. After subgroup analysis, blood transfusion on admission [OR 1.97 (95 % CI 1.16-3.35) p ≤0.05 I2 5 %] and barbiturate infusion [OR 3.55 (95 % CI 2.01-6.30) p ≤0.05 I2 0 %] became risk factors. Prophylactic antibiotic use [OR 0.67 (95 % CI 0.51-0.88) p ≤0.05 I2 0 %] and younger age MD -3.29 (95 % CI -5.18, -1.40) p ≤0.05 I2 41 %] emerged as significant protective factors. In VAP patients ICU stay [MD 7.02 (95 % CI 6.05-7.99) p ≤0.05 I2 37 %], duration of mechanical ventilation [MD 5.79 (95 % CI 4.40, 7.18) p ≤0.05 I2 79 %] and hospital stay [MD 11.88 (95 % CI 8.71-15.05) p ≤0.05 I2 0 %] were significantly increased. The certainty of the evidence was moderate-high for the outcomes studied. CONCLUSIONS: Male gender, H-AIS ≥ 3, blood transfusion on admission, and barbiturate infusion were risk factors for VAP. In patients with VAP, ICU stay, duration of mechanical ventilation, hospital stay were significantly increased.

Clinical and Nutritional Aspects and Outcomes of Covid-19 in Cancer and Non-Cancer Pediatric Patients.

The SARS-CoV-2 virus has been the subject of study by several researchers worldwide since 2020; however, there are points to be clarified. This study aimed to analyze the clinical and nutritional aspects of hospitalized cancer and non-cancer pediatric patients and the association with COVID-19 outcomes. This is a cohort study of hospitalized children and adolescents with a laboratory diagnosis of COVID-19. Patients were assessed according to the presence or absence of previous oncological diseases. Sociodemographic, clinical and nutritional data were investigated during the course of the infection. Outcomes included Intensive Care Unit (ICU) admission, longer length of stay (14 days), criticality, and death. Oncological disease was found in 16 (19.3%) patients, most of whom had B-type acute lymphoid leukemia. In Poisson regression, adjusted for age and comorbidity, an association was found between oncological disease and length of stay ≥14 days (RR 4.30; 95% CI 1.46 - 15.6; p = 0.013), COVID-19 criticality (RR 3.82; 95% CI 1.66 - 30.9; p = 0.010) and death (RR 3.42; 95% CI 0.94 - 9.96; p = 0.035). The research revealed that cancer patients had longer hospital stays, were more likely to have the severe form of COVID-19, and had a 3.42 times greater risk of dying.

Direct healthcare costs for people with cerebral palsy in the Brazilian unified health system between 2015 and 2019.

BACKGROUND: Estimate the costs of inpatient and outpatient care for people with Cerebral Palsy (CP) in Brazil. RESEARCH DESIGN AND METHODS: Health records of people with CP in the Hospital and Outpatient Information Systems of Brazil between 2015 and 2019 were analyzed. Variables analyzed were gender, age, ICD, Intensive Care Unit (ICU) use, total cost, and ICU cost. Costs were adjusted for inflation and converted to dollars. Linear regression analysis was performed to investigate the association between social and clinical variables and direct costs. RESULTS: A total direct cost of approximately $166 million to the National Health System was identified, with $7.08 million/year and $26.1 million/year of inpatient and outpatient costs, respectively. The healthcare was primarily for children up to 14 years of age. The ICD 'spastic quadriplegic CP' received the most attendance. Rehabilitation was responsible for 75% of the outpatient care, with physiotherapy standing out. Increased age, use of ICU, and the types of CP are related to increased cost. CONCLUSIONS: Healthcare for people with CP produced expressive costs for the Brazilian public health system, mainly with outpatient procedures and rehabilitation, with children being the most attended. Estimating these costs assist in better resource allocation for more effective healthcare provision.

Postoperative oliguria after intermediate and high-risk surgeries in critical care, A cohort analysis.

INTRODUCTION: Oliguria is commonly used as a cutoff for acute kidney injury (AKI), however, a decrease in urine output is common during surgery and may represent an adaptative response in the perioperative setting rather than a reduction in glomerular filtration rate, leading to a possible overestimation of postoperative AKI incidence. Although this dilemma has been addressed in the intraoperative scenario, the incidence and impact of oliguria in the first postoperative day represents a gap in the current literature. Our main goal is to describe the incidence, risk factors and clinical outcomes related to postoperative oliguria. METHODS: This was a retrospective cohort conducted in four intensive care units (ICUs) across two private Brazilian hospitals, analyzing patients admitted after intermediate and high-risk surgeries between January 1, 2018 and December 31, 2022. RESULTS: 1476 patients were included in the final analysis. Overall, 656 (44,5 %) were males, and the median age was 61,7 years. Oliguria was identified in 508 (34,4 %) patients within the first 24 h after surgery. Vasopressor requirement at admission, non-elective procedures, male sex and baseline serum creatinine were higher among oliguric patients. Among oliguric patients, age and basal serum creatine were higher among those who experienced AKI. Although only 12,4 % of oliguric patients developed AKI according to serum creatinine criterion, this incidence was significantly higher than in non-oliguric group (3,6 %), RR 3.42, IC 95 % 2.3-5.1 (p < 0.01). AKI recovery, RRT, ICU and hospital free days, and mortality were similar between the groups. CONCLUSIONS: Postoperative oliguria is common after intermediate and high-risk surgical procedures and increases the risk of AKI. However, oliguria was largely unrelated with kidney disfunction measured by serum creatinine (87,6 %), raising doubts on whether diuresis overestimates AKI incidence in the postoperative setting.

Effect of Early Multiprofessional Mobilization on Quality Indicators of Intensive Care in a Less Economically Developed Country: An Action on "Rehabilitation 2030" in Brazil.

OBJECTIVE: To investigate the effects of implementing early multiprofessional mobilization on quality indicators of intensive care in Brazil. DESIGN: This is a retrospective cohort study. SETTING: A Brazilian educational and research-intensive care unit (ICU). PARTICIPANTS: A total of 1047 patients were hospitalized from May 2016 to April 2018. INTERVENTIONS: Implementation of early multiprofessional mobilization using the MobilizAÇÃO Program (MAP). MAIN OUTCOME MEASURES: Clinical, ventilation and safety quality indicators, and physical function before (preprogram period) and after (postprogram period) the MAP. RESULTS: There was a reduction in sedation time (4 vs 1d), hospital stay (21 vs 14d) and ICU stay (14 vs 7d), mechanical ventilation (8 vs 4d), hospital death rate (46% vs 26%) (P<.001), and ICU readmission (21% vs 16%; P=.030) from pre to post MAP. Successful weaning (42% vs 55%) and discharge rate (50% vs 71%) (P<.001) increased after MAP. No differences were found to safety quality indicators between periods. After MAP, complex physical functions assessed using the Manchester Mobility Score (MMS) were more frequent. The in-bed intervention was a predictor for readmission (P=.009; R²=0.689) and death (P=.035; R²=0.217), while walking was a predictor for successful weaning (P=.030; R²=0.907) and discharge (P=.033; R²=0.373). The postprogram period was associated with the MMS at ICU discharge (P<.001; R²=0.40). CONCLUSIONS: Early mobilization implementation through changes in low mobility culture and multiprofessional actions improved quality indicators, including clinical, ventilation, and physical functional quality, without compromising patient safety in the ICU.

Oral care practices for patients in intensive care unit: A systematic review.

OBJECTIVES: To critically analyse and discuss oral hygiene protocols in the hospital environment in patients admitted to the ICU, through a systematic review of the literature. METHODS: The electronic search was performed on Pubmed, Cochrane, Web of Science and Google Scholar databases. The indexing keywords according to the PRISMA protocol were: 'hospital dentistry', 'oral health', 'oral care' and 'intensive care unit'. RESULTS: The initial search resulted in a total of 2671 articles. Pre-selection based on titles led to the exclusion of 2510 articles and the remaining 36 were selected for abstract reading. After analysing the eligibility of the articles, eight studies were included in the review and submitted to qualitative analysis. CONCLUSION: It can be concluded that cleaning with a soft bristle brush, use of chlorhexidine and lip moisturizing are methods commonly used in dental care actions in patients hospitalized in intensive care units.

Oral hygiene in critically ill patients at a tertiary hospital in São Paulo, Brazil: a best practice implementation project.

OBJECTIVES: This project aimed to promote evidence-based practices relat. ed to the oral health of critically ill patients in an intensive care unit in Brazil. INTRODUCTION: The oral hygiene of patients on mechanical ventilation is an essential component of nursing care quality, and well-defined guidelines ensure appropriate care. Mechanical ventilation is associated with the risk of ventilator-associated pneumonia, which can increase mortality, length of stay, time on mechanical ventilation, and hospital costs. METHODS: This project was guided by the JBI Evidence Implementation Framework, which consists of seven stages: (1) identification of the area of practice to be changed, (2) involvement of change agents, (3) context assessment and readiness for change, (4) review of practices against evidence-based audit criteria, (5) implementation of practice changes, (6) reassessment of practices using a follow-up audit, and (7) consideration of the sustainability of changes in practice. RESULTS: Four audit criteria were developed to evaluate compliance with best practices. In the follow-up audit, Criteria 1, 2, and 3 obtained compliance of ≥ 80%. Thus, for Criterion 1, all the patients on mechanical ventilation for more than 24 hours were evaluated by the oral medicine team, resulting in 100% compliance. For Criterion 2 on appropriate oral hygiene measures, a compliance rate of 80% was achieved. For Criterion 3, 39 professionals (90.7%) participated in educational activities related to the oral health protocol for critically ill patients, obtaining 90.7% compliance. For Criterion 4 regarding patients being evaluated before receiving any oral health care, improvement was low (only 50%), revealing the need for further improvement. CONCLUSION: This best practice project improved the professional practice of nursing staff and increased compliance with best practices for the oral health of critically ill patients.

Very old patients in the ICU in Latin America: A narrative review.

The population of very elderly patients (aged 80 years and older) in intensive care units (ICUs) is steadily growing. These patients have unique physiological, cognitive, functional, and social characteristics that affect their entire ICU course. Immobility, delirium, dysphagia, malnutrition, and polypharmacy are among the most common geriatric syndromes in these patients, and they contribute to a higher risk of acute and long-term functional decline and mortality. Risk assessment in very elderly patients is complex, as traditional ICU scoring systems do not account for frailty and baseline disability, making difficult the determination of likely benefits, futility, or harm with ICU interventions. The importance of shared decision-making for treatment plans is critical, as very elderly patients and their families may have uncertain or unrealistic prognostic awareness and expectations of ICU care. Considering the gap between the rapid aging of the population and the socio-health development in Latin America, this population is an important determinant of stress on healthcare systems, however, data on these population is scarce. This review, based on a comprehensive literature search, summarizes recent evidence on triage for ICU admission, specific clinical characteristics, predictive elements of prognosis, and ICU and post-ICU outcomes for very elderly patients while also analyzing the challenges to improve management in the Latin American region.

Ventilator-associated pneumonia risk factors in patients with severe COVID-19 in southern Brazil: A retrospective observational study.

BACKGOUND: During the SARS-CoV-2 pandemic, a significant number of critical patients required ventilatory assistance in health institutions. In this context, Ventilator-Associated Pneumonia (VAP) was the most prevalent nosocomial infection among critically ill patients. We aimed to analyze the occurrence of VAP in critically ill patients with SARS-CoV-2 and the risk factors associated with the outcome. METHOD: This is a multicenter, retrospective cohort study which included patients ≥18 years old, diagnosed with COVID-19, admitted to intensive care units (ICU) and who received invasive mechanical ventilation (MV) for >2 consecutive days. The associations between the variables were initially tested, and those that showed potential associations (p<0.05) were included in the multivariate logistic regression model. RESULTS: One third of patients had an episode of VAP, with an incidence density of 34.97 cases per 1000 MV days. In addition, 42.37% (50) of the microorganisms causing VAP were multidrug-resistant, predominantly gram-negative bacteria (61.32%). More than 50% of participants developed healthcare-associated infections and 243 (73.64%) died. The factors associated with greater chances of VAP were: prone position (OR= 3.77), BMI 25-29.9 kg/m2 (OR= 4.76), pressure injury (OR= 4.41), length of stay in the ICU (OR= 1.06), positive tracheal aspirate before VAP (OR= 5.41) and dyspnea (OR= 3.80). CONCLUSIONS: Patients with COVID-19 are at high risk of VAP, which leads to an increased risk of death (OR = 2.18). Multiple factors increase the chances of VAP in this population, namely: work overload in health institutions, prone position, prolonged ICU time, infusion of multiple drugs, invasive devices, and in particular, immobility in bed.

Improvement in antibacterial use in intensive care units from Argentina: A quality improvement collaborative process evaluation using Normalization Process Theory.

BACKGROUND: Healthcare-associated infections and antibiotic resistance worsen globally. Antibiotic stewardship programs (ASP) aim to optimise infection treatment and curb resistance, yet implementation hurdles persist. This study examined ASP challenges in ICUs. METHODS: This study employed a qualitative methodological design to evaluate the implementation process of an antibiotic stewardship program (ASP) in eight intensive care units (ICUs) across Argentina. Thirty-four semi-structured interviews with healthcare workers (HCWs) were conducted. Interviews were analysed guided by Normalisation Process Theory, examining coherence, cognitive participation, collective action, and reflexive monitoring constructs. RESULTS: Key challenges included insufficient human resources, lack of institutional support, and resistance to change, particularly among staff not initially involved in the study. Despite these challenges, the program saw partial success in improving ICU practices, particularly in antibiotic use and communication across departments. The main strategy implemented in this quality improvement collaborative was the use of improvement cycles, which served as the central component for driving change. However, participation in improvement cycles was inconsistent, and sustainability post-intervention remains uncertain due to workload pressures and the need for continuous education. Concerns about workload and communication barriers persisted. Many participants did not perceive training as a separate component, which led to low engagement. Resistance to change became evident during modifications to clinical guidelines. The intervention had a positive impact on various processes, including communication and record keeping. CONCLUSION: This study underscores the persistent challenges in implementing ASPs in healthcare, emphasising the need for enhanced collaboration, workforce capacity building, and evidence-based practices to overcome barriers and optimize antimicrobial use to improve patient outcomes.

Correlation between corrected carotid flow time and left ventricular outflow tract velocity-time integral using a novel technique.

BACKGROUND: Transthoracic echocardiography (TTE) is widely used for assessing patients in the intensive care unit, with cardiac output measurement being crucial for hemodynamic monitoring. This is achieved by measuring the velocity-time integral (VTI) of the left ventricular outflow tract (LVOT), which serves as a surrogate of stroke volume. However, conducting TTE in the critical care setting presents several challenges. Our primary objective was to investigate the relationship between carotid corrected flow time (cCFT) and LVOT VTI. Additionally, we aimed to determine the threshold cCFT value that reliably predicts a normal LVOT VTI. MATERIALS AND METHODS: This proof-of-concept study involves a post-hoc analysis from a diagnostic accuracy investigation conducted in a medical-surgical intensive care unit. We included patients admitted to the ICU from December 2021 to January 2022. We used a phased array transducer to measure the cCFT at the left supraclavicular fossa and the LVOT VTI in an apical 5-chamber view. RESULTS: We included 22 patients. The Spearman coefficient between LVOT VTI and cCFT was 0.82 (p < 0.0001). The area under the ROC curve for cCFT to predict LVOT VTI equal to or greater than 17 cm was 0.871 (95% CI 0.660-0.974). A cCFT exceeding 283 ms predicted LVOT VTI equal to or greater than 17 cm with a sensitivity of 93.3% (95% CI 68.1% to 99.8%) and specificity of 85.7% (95% CI 42.1% to 99.6%). CONCLUSION: The cCFT, measured using a novel technique with a phased array transducer, shows a strong correlation with LVOT VTI. Additionally, cCFT predicts a normal LVOT VTI with good sensitivity and specificity in critically ill patients. Larger studies are warranted to validate these findings.

Nurses' Advocacy in Intensive Care: What Insights Can Nurses' Experiences During the Pandemic Reveal?

Patient advocacy must be understood as an ethical component of nursing practice that involves respecting and defending patients' rights and autonomy. During the COVID-19 pandemic, the vulnerability of patients in intensive care units (ICUs) increased requiring that nurses advocate for those patients more than ever in a context in which changes in daily nursing practices of care imposed by the pandemic deeply impacted nurses' advocacy. In this study, we examined ICU nurses' patient advocacy during the pandemic, using feminist ethics as a theoretical lens. Twenty-five ICU nurses from Brazil participated in individual interviews. Our findings reflect that advocacy is a moral component of nursing identity. This moral identity represents the identity of nurses as a profession as it represents their values and responsibilities which are social in nature. Although the pandemic challenged nurses' advocacy practices these professionals had an important role to give voice to patients and to preserve their autonomy and dignity, strengthening patient-centered care.

Pressure injury prevention in an intensive care unit: implementing the best practices.

OBJECTIVE: to implement the best evidence in preventing pressure injuries in patients in the intensive care unit of a university hospital in the city of São Paulo/Brazil. METHOD: a quasi-experimental study whose intervention was implementing evidence based on the Joanna Briggs Institute methodology, which includes auditing and feedback. Ten audit criteria were used, which were verified in patient records and training records of the teaching and quality service. The intervention was assessed by comparing the percentage of compliance with audited criteria before and after implementing the best practices. Pearson's chi-squared test was used. RESULTS: 2,677 days of baseline and follow-up audit records were evaluated, regarding 340 patients. Compliance baseline and follow-up audits differed for most criteria (p-value <0.001). The main barriers were the lack of records of essential information on pressure injuries in the medical records, and strategies for overcoming these barriers included a review of the pressure injury prevention protocol and training of the nursing team. CONCLUSION: the intervention adopted contributed to improving practices regarding the prevention of pressure injuries, expressed by the increase in the rate of compliance with the criteria and the proposal of improvement strategies to overcome barriers.

Incidence of pressure injuries in critically ill patients with and without covid-19: study of Cohort.

OBJECTIVE: To compare the incidence, characteristics, and risk factors of pressure injuries among critically ill patients with and without Covid-19 in an intensive care unit. METHOD: Retrospective cohort study in an intensive care unit by collecting data from electronic medical records of patients admitted in 2021. Sample of 302 patients, 151 with Covid-19 and 151 without Covid-19. Poisson's regression with robust variance and p < 0.05 as a significant value was used to analyze the data. RESULTS: The incidence of pressure injuries in patients with Covid-19 was 60.3% and in those without Covid-19 were 35.8%. Stage 2 and the sacral region were predominant in both groups and patients with Covid-19 developed lesions earlier compared to those without Covid-19. An increase in pressure injuries was observed in patients with chronic diseases, on mechanical ventilation and in the prone position The clinical variables associated were "obesity," "Braden ≤ 12," and "sedation time." CONCLUSION: The incidence of pressure injuries was higher in patients with Covid-19.The variables "obesity," "Braden ≤ 12," and "sedation time" were associated with pressure injuries, regardless of whether the patient had Covid-19 or not, corroborating risk factors for pressure injuries.

Comparison of subclavian vein and inferior vena cava collapsibility index in the intensive care unit.

OBJECTIVE: The aim of this study was to evaluate the correlation between changes in the inferior vena cava collapsibility index and subclavian vein collapsibility index in patients undergoing passive leg raising tests in the intensive care unit, considering that respiratory changes affecting the inferior vena cava may similarly affect the subclavian vein. METHODS: This single-center observational study was conducted on patients aged between 18 and 85 years who underwent passive leg raising in the intensive care unit. When the patient was 45° above the bed, the inferior vena cava and subclavian vein were displayed using ultrasonography; subclavian vein collapsibility index and inferior vena cava collapsibility index values were calculated. After the initial values were recorded, passive leg raising was performed, and the initial measurements were repeated. The CI values measured after passive leg raising were subtracted from those calculated before passive leg raising to determine the changes (Δ) in inferior vena cava and subclavian vein collapsibility indices. RESULTS: The study was conducted with a total of 64 patients. The mean±standard deviation values for ΔIVC-CI% and ΔSCV-CI% variables were found as 8.97±8.89 and 10.31±10.81, respectively. There were no statistically significant differences in values of ΔIVC-CI% and ΔSCV-CI% (p=0.297). In the Bland-Altman plot, because there were only two values exceeding the +1.96 SD and -1.96 SD limits, it can be said that the agreement between ΔIVC-CI% and ΔSCV-CI% was adequate. CONCLUSION: ΔSCV-CI% values are compatible and correlated with ΔIVC-CI% values. Inferior vena cava and subclavian vein responded similarly to fluid changes during passive leg raising.

Scientific output and organizational characteristics in Brazilian intensive care units: a multicenter cross-sectional study.

OBJECTIVE: To examine the associations between the scientific output of Brazilian intensive care units and their organizational characteristics. METHODS: This study is a re-analysis of a previous retrospective cohort that evaluated organizational intensive care unit characteristics and their associations with outcomes. We analyzed data from 93 intensive care units across Brazil. Intensive care units were assessed for scientific productivity and the effects of their research activities, using indicators of care for comparison. We defined the most scientifically productive intensive care units as those with numerous publications and a SCImago Journal Rank score or an H-index above the median values of the participating intensive care units. RESULTS: Intensive care units with more publications, higher SCImago Journal Rank scores and higher H-index scores had a greater number of certified intensivists (median of 7; IQR 5 - 10 versus 4; IQR 2 - 8; with p < 0.01 for the comparison between intensive care units with more versus fewer publications). Intensive care units with higher SCImago Journal Rank scores and H-index scores also had a greater number of fully implemented protocols (median of 8; IQR 6 - 8 versus 5; IQR 3.75 - 7.25; p < 0.01 for the comparison between intensive care units with higher versus lower SCImago Journal Rank scores). CONCLUSIONS: Scientific engagement was associated with better staffing patterns and greater protocol implementation, suggesting that research activity may be an indicator of better intensive care unit organization and care delivery.

Impact of Hurricane Maria on the mortality of patients admitted to the MICU at the VA Caribbean Healthcare System in Puerto Rico.

OBJECTIVE: This study aims to assess the impact of Hurricane Maria on mortality rates and patient conditions in the Medical Intensive Care Unit (MICU) at the Veterans Affairs Caribbean Healthcare Hospital in San Juan, Puerto Rico (PR). The focus is on the 2 months before and after the hurricane's landfall. DESIGN: This is a retrospective, transversal study. SETTING: The intensive care unit at the Veteran Affairs Caribbean Healthcare System in San Juan, PR. PARTICIPANTS: A total of 202 patients, sampled using a time-defined method, aged 21-90 years, were admitted to the MICU between July 16, 2017, and November 16, 2017. MAIN OUTCOME MEASURE(S): The primary measure is the mortality rate of MICU patients during the specified period. Secondary measures include the severity of patient conditions and changes in the causes of death, particularly cardiovascular deaths. RESULTS: The overall mortality rate in the MICU did not significantly change following Hurricane Maria. However, there was an increase in cardiovascular-related deaths. In addition, patient conditions showed higher severity post-hurricane, as indicated by Apache II scores, along with prolonged hospital stays and altered admission patterns for specific conditions. CONCLUSIONS: While Hurricane Maria did not significantly alter overall mortality rates in the MICU, the increase in cardiovascular deaths and more severe post-hurricane patient conditions underscore the need for enhanced disaster preparedness and response strategies in critical care settings.

Differences in the relative importance of predictors of short- and long-term mortality among critically ill patients with cancer.

OBJECTIVE: To identify the relative importance of several clinical variables present at intensive care unit admission on the short- and long-term mortality of critically ill patients with cancer after unplanned intensive care unit admission. METHODS: This was a retrospective cohort study of patients with cancer with unplanned intensive care unit admission from January 2017 to December 2018. We developed models to analyze the relative importance of well-known predictors of mortality in patients with cancer admitted to the intensive care unit compared with mortality at 28, 90, and 360 days after intensive care unit admission, both in the full cohort and stratified by the type of cancer when the patient was admitted to the intensive care unit. RESULTS: Among 3,592 patients, 3,136 (87.3%) had solid tumors, and metastatic disease was observed in 60.8% of those patients. A total of 1,196 (33.3%), 1,738 (48.4%), and 2,435 patients (67.8%) died at 28, 90, and 360 days, respectively. An impaired functional status was the greatest contribution to mortality in the short term for all patients and in the short and long term for the subgroups of patients with solid tumors. For patients with hematologic malignancies, the use of mechanical ventilation was the most important variable associated with mortality in all study periods. The SOFA score at admission was important for mortality prediction only for patients with solid metastatic tumors and hematological malignancies. The use of vasopressors and renal replacement therapy had a small importance in predicting mortality at every time point analyzed after the SOFA score was accounted for. CONCLUSION: Healthcare providers must consider performance status, the use of mechanical ventilation, and the severity of illness when discussing prognosis, preferences for care, and end-of-life care planning with patients or their families during intensive care unit stays.

Perceptions and preferences about family visitation restrictions and psychological distress among critical care clinicians in Brazil: results from a national survey.

OBJECTIVE: To explore the perceptions of healthcare workers in the intensive care unit about family visitation policies and to examine their impact on healthcare workers' psychological distress. METHODS: We disseminated an electronic survey to interdisciplinary healthcare workers via the Associação de Medicina Intensiva Brasileira during Brazil's most severe peak of COVID-19 (March 2021). We assessed perceptions of and preferences for family visitation policies and measured healthcare worker distress, including burnout, depression, anxiety, irritability, and suicidal thoughts using validated scales. We conducted multivariable regressions to evaluate factors associated with healthcare worker distress, including family visitation policies and healthcare workers' concerns. RESULTS: We included responses from 903 healthcare workers: 67% physicians, 10% nurses, 10% respiratory therapists, and 13% other. Most healthcare workers reported that their hospitals allowed no family visitation (55%) or limited visitation (43%), and only 2% reported allowing unlimited visitation. Most believed that limiting visitation negatively impacted patient care (78%), and 46% preferred allowing more visitation (which was lower among nurses [44%] than among physicians [50%]; p < 0.01). Approximately half (49%) of healthcare workers reported that limited visitation contributed to their burnout, which was lower among nurses (43%) than among physicians (52%), p = 0.08. Overall, 62% of healthcare workers reported burnout, 24% reported symptoms of major depression, 37% reported symptoms of anxiety, 11% reported excessive alcohol/drug consumption, and 14% reported thoughts of hurting themselves. In the multivariable analysis, family visitation policies (limited visitation versus no visitation) and preferences about policies (more visitation versus same or less) were not associated with psychological distress. Instead, financial concerns and reporting poor communication with supervisors were most strongly associated with burnout, depression, and anxiety. CONCLUSION: Half of healthcare workers self-reported that limited family visitation contributed to their burnout, and most felt that it negatively impacted patient care. However, family visitation preferences were not associated with healthcare worker distress in the multivariable regressions. More physicians than nurses indicated a preference for more liberal visitation policies.

CPAP delivered via a helmet interface in lightly sedated patients with moderate to severe ARDS: predictors of success outside the ICU.

OBJECTIVE: This study aimed to describe the outcomes and explore predictors of intubation and mortality in patients with ARDS due to COVID-19 treated with CPAP delivered via a helmet interface and light sedation. METHODS: This was a retrospective cohort study involving patients with COVID-19-related ARDS who received CPAP using a helmet developed in Brazil (ELMO™), associated with a light sedation protocol in a pulmonology ward. Demographic, clinical, imaging, and laboratory data, as well as the duration and response to the ELMO-CPAP sessions, were analyzed. RESULTS: The sample comprised 180 patients. The intubation avoidance rate was 72.8%. The lack of necessity for intubation was positively correlated with younger age, > 24-h continuous HELMET-CPAP use in the first session, < 75% pulmonary involvement on CT, and ROX index > 4.88 in the second hour. The overall in-hospital mortality rate was 18.9%, whereas those in the nonintubated and intubated groups were 3.0% and 61.2%, respectively. Advanced age increased the mortality risk by 2.8 times, escalating to 13 times post-intubation. CONCLUSIONS: ELMO-CPAP with light sedation in a pulmonology ward was successful in > 70% of patients with moderate to severe ARDS due to COVID-19. Younger age, pulmonary involvement, ROX index, and prolonged first Helmet-CPAP session duration were associated with no need for intubation. Older age and intubation are associated with mortality.
