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.

Visual Acuity Thresholds in Preterm Newborns: An Experimental Study.

Purpose: Visual acuity plays a role in mediating neurological development in infants by enabling the differentiation of shapes and discriminating objects. Given the rapid structural development of the brain in the first days of life, this aspect is particularly significant for preterm infants, who typically experience this developmental phase while hospitalized in the neonatal intensive care unit (NICU). Therefore, this study aimed to assess visual acuity thresholds in preterm infants during hospitalization and to evaluate possible correlations between visual acuity and clinical parameters. Methods: A cross-sectional study was conducted in an NICU in Northeast Brazil. The visual acuity thresholds were tested using the Teller Acuity Cards II, comprised of 17 gray cards, with one 4 mm diameter peephole at the center and presented with about 35% reflectance. Preterm infants were positioned supine, at 30° elevation on the laps of their caregivers. The evaluator presented both sides of the cards and observed the eye fixation and reactions on both sides. Results: A total of 42 preterm infants with corrected gestational age between 30 to 36 weeks and 6 days were included. Visual acuity ranged from 0.23 to 0.64 cycle per degree. The mean visual acuity threshold was 0.32 cycles per degree for preterm infants at around 32 weeks of corrected gestational age. The visual acuity was not correlated with gestational age (p = 0.18), and neither were birth weight (p = 0.83) or duration of respiratory support (p = 0.98). However, days of phototherapy were inversely correlated with visual acuity (p = 0.04). Conclusions: Despite the challenges of hospitalization, it was possible to carry out a psychophysical test to assess visual acuity in preterm infants. The visual acuity showed no correlation with clinical parameters such as gestational age, birth weight, and duration of respiratory support. However, there was an inverse correlation between the number of days in phototherapy and visual acuity. Understanding the visual acuity levels in preterm infants during their NICU stay can contribute to tailoring interventions and care strategies that specifically address their visual developmental needs. This knowledge may guide healthcare professionals in optimizing the NICU environment to provide appropriate visual stimuli that support neurological development.

ABSTRACT Objectives. To determine the requirement and time to mechanical ventilation and Intensive Care Unit (ICU), hospitalization and hospitalization time, death and disability of the axonal variants of Guillain-Barré Syndrome (GBS) in comparison with the acute demyelinating variant in patients of all the ages. Materials and methods. The systematic review that included patients with GBS. The exposure variable was the axonal variants and the comparator was acute inflammatory demyelinating polyneuropathy (AIDP). The outcomes were the requirement and time on mechanical ventilation (MV), requirement and time in the ICU, hospitalization time, disability and death. The NewCasttle-Ottawa Scale (NOS) was used to assess risk of bias. A meta-analysis was conducted to calculate mean differences and relative risks (RR) with their 95% confidence intervals (CI) using inverse variances and random effects models. Results. Of the 3116 articles found, 46 met the selection criteria. The time on MV was 7.42 days (95% CI: 0.36 to 1.48) and the hospitalization time was 3.11 (95% CI: 0.73 to 5.49) days for the axonal variants. The axonal variants had a RR of 0.47 (95% CI: 0.24 to 0.92) for the requirement of MV in adults, but it was 1.68 (95% CI: 1.25 to 2.25) in children. There was a high statistical heterogeneity. Conclusions. Axonal variants showed, on average, longer MV and hospitalization time, overall and by subgroups. A high MV requirement was found for axonal variants in children; it was lower for adults.

Long-term effects of flexible visitation in the intensive care unit on family members' mental health: 12-month results from a randomized clinical trial.

PURPOSE: The aim of this study was to assess the effects of flexible intensive care unit (ICU) visitation on the 1-year prevalence of post-traumatic stress, anxiety and depression symptoms among family members of critically ill patients. METHODS: This is a long-term outcome analysis of a cluster-crossover randomized clinical trial that evaluated a flexible visitation model in the ICU (12 h/day) compared to a restrictive visitation model (median 1.5 h/day) in 36 Brazilian ICUs. In this analysis, family members were assessed 12 months after patient discharge from the ICU for the following outcomes: post-traumatic stress symptoms measured by the Impact Event Scale-6 and anxiety and depression symptoms measured by the Hospital Anxiety and Depression Scale. RESULTS: A total of 519 family members were analyzed (288 in the flexible visitation group and 231 in the restrictive visitation group). Three-hundred sixty-nine (71.1%) were women, and the mean age was 46.6 years. Compared to family members in the restrictive visitation group, family members in the flexible visitation group had a significantly lower prevalence of post-traumatic stress symptoms (21% vs. 30.5%; adjusted prevalence ratio [aPR], 0.91; 95% confidence interval [CI] 0.85-0.98; p = 0.01). The prevalence of anxiety (28.9% vs. 33.2%; aPR 0.93; 95% CI 0.72-1.21; p = 0.59) and depression symptoms (19.2% vs. 25%; aPR, 0.78; 95% CI 0.60-1.02; p = 0.07) did not differ significantly between the groups. CONCLUSION: Flexible ICU visitation, compared to the restrictive visitation, was associated with a significant reduction in the 1-year prevalence of post-traumatic stress symptoms in family members.

Evaluation of the use of telemedicine in pediatric intensive care units: a cluster-randomized trial.

INTRODUCTION: Telemedicine has shown promising results, allowing specialists to provide rapid and effective care in remote locations. However, to our knowledge, current evidence is not robust enough to prove the effectiveness of this tool. This cluster-randomized trial (CRT) aimed to evaluate the impact of telemedicine on clinical care indicators in pediatric intensive care units (PICUs). METHODS: An open-label CRT was conducted in 16 PICUs within the Brazilian public health system. The trial took place from August 2022 to December 2023 and compared an intervention group, which received telemedicine support, with a control group, which received usual PICU care. The primary outcome was the PICU length of stay. The main secondary outcomes were mortality rate and ventilator-free days. RESULTS: A total of 1393 participants were included, 657 in the control group and 736 in the intervention group. The mean PICU length of stay was 10.42 (SD, 10.71) days for the control group and 11.52 (SD, 10.80) days for the intervention group. The overall mean of ventilator-free days was 6.82 (SD, 7.71) days. Regarding mortality, 7.54% of participants died in total. No significant difference was found in the outcomes between the groups. CONCLUSION: Despite the potential benefits of telemedicine, its effective implementation in the Brazilian public health system faces considerable challenges, highlighting the continued importance of investigating and improving the role of telemedicine in pediatric critical care. CLINICAL TRIAL REGISTRATION: ClinicalTrials.gov NCT05260710 and ReBEC - RBR-7×j4wyp.

Analysis of the influence of occupational, sociodemographic and health factors on the demotivation of the intensivist.

Introduction: Understanding motivation, identifying motivational factors of health professionals, and recognizing how managers and leaders can successfully motivate healthcare professionals is a growing concern. Objectives: To assess the occupational, sociodemographic, and health factors that influence the occurrence of demotivation in the intensive care unit professionals. Methods: We performed a cross-sectional study with health professionals from nine intensive care units in João Pessoa, Paraíba state, Brazil. Data were collected using an adapted version of the Health Care Establishment Questionnaire. We built a Logistic Regression model to analyze the influence of variables on the motivational state, and variables were selected by the Backward method. We used 80% of the sample for parameter estimation and the remaining 20% for testing and validation. We used the R software for the analyses, with a significance level of α ≤ 0.05. Results: We identify that the variable with the greatest power over the intensivist's demotivation was shift work (odds ratio [OR] = 4.215, p = 0.006). The number of symptoms (OR = 1.206, p = 0.000) and working time (OR = 1.080, p = 0.031) were also significant risk variables. When the three variables were combined, the professional's chance of feeling unmotivated increased by 38 times (OR = 38.99, p = 0.000). Conclusions: Based on these results, it is possible to identify aspects that will require organizational adjustments so that intensivists remain satisfied and motivated.

Introdução: Há uma crescente preocupação em relação a entender os fenômenos da motivação, identificar os fatores motivadores dos profissionais de saúde e reconhecer como o gestor e os líderes conseguem motivar a equipe com sucesso. Objetivo: Avaliar os fatores ocupacionais, sociodemográficos e de saúde que influenciam na ocorrência de desmotivação no profissional de saúde intensivista. Métodos: Tratou-se de um estudo transversal, realizado com profissionais de saúde de nove unidades de terapia intensiva localizadas em João Pessoa, no estado da Paraíba, Brasil. Os dados foram coletados por meio de uma versão adaptada do Health Care Establishment Questionnaire. Para análise da influência das variáveis sobre o estado motivacional, construiu-se um modelo de regressão logística, com seleção de variáveis pelo método backward. Utilizou-se 80% do total da amostra para estimação dos parâmetros, e os 20% restantes foram usados para o teste e a validação dos resultados. As análises foram realizadas no software R, com nível de significância de α ≤ 0,05. Resultados: Identificou-se que a variável com maior poder sobre a desmotivação do intensivista foi o trabalho em turnos (razão de chances [OR] = 4,215, p = 0,006). O quantitativo de queixas sintomatológicas (OR = 1,206, p = 0,000) e o tempo de trabalho (OR = 1,080, p = 0,031) também foram variáveis significativas sobre o risco. Quando as três variáveis estiveram combinadas, aumentou-se em 38 vezes a chance de o profissional se sentir desmotivado (OR = 38,99, p = 0,000). Conclusões: Com base nesses resultados, é possível identificar aspectos do trabalho que exigem ajustes organizacionais para que os intensivistas mantenham-se satisfeitos e motivados.

Oxygen delivery and monitoring in neonatal intensive care units in Mexico in 2011 and in 2023: an observational longitudinal study.

BACKGROUND: Retinopathy of prematurity (ROP) is a leading cause of avoidable blindness in children, particularly in Latin America, where hyperoxia is a significant risk factor. This study evaluated resource availability and use for administering and monitoring supplemental oxygen in Mexico. METHODS: In 2011, an observational study in which 32 government neonatal intensive care units (NICUs) across Mexico were visited. Data collected included occupancy, staffing levels, and equipment to deliver and monitor supplemental oxygen. Preterm infants receiving oxygen were observed. In 2023, 13 NICUs were revisited, and similar data collected. Staffing levels were benchmarked against Argentinian and US recommendations. RESULTS: In 2011, only 38% of NICUs had adequate medical and staffing levels to meet recommended cot-to-staff ratios for all shifts. Staffing ratios were worse during weekends and at night than during weekdays. Only 25.5% of cots had blenders, and 80.1% had saturation monitors. 153 infants were observed 87% of whom were being monitored. Upper and lower oxygen saturations were ≥ 96% in 53%, and ≤ 89% in 8%, respectively. Alarm settings were inadequate, as 38% and 32% of upper and lower alarms were switched off and 16% and 53% were incorrectly set, respectively. In the 13 NICUs with data from 2011  and 2023, cot-to-staff ratios deteriorated over time, and in 2023 no unit had recommended ratios for all shifts. Equipment provision did not change, with similar proportions of babies in oxygen being monitored (79% 2011; 75% 2023). Rates of hyperoxia decreased slightly from 54% in 2011 to 49% in 2023. More upper alarms were set (46% 2011; 75% 2023), but a higher proportion were incorrectly set (52% 2011; 68% 2023). CONCLUSIONS: Between 2011 and 2023, cot-to-staff ratios worsened, and equipment for safe oxygen delivery and monitoring remained insufficient. Despite available monitoring equipment, oxygen saturations often exceeded recommended levels, and alarms were frequently not set or incorrectly configured. Urgent improvements are needed in healthcare workforce numbers and practices, along with ensuring adequate equipment for safe oxygen delivery.

Towards better mortality prediction in cancer patients in the ICU: a comparative analysis of prognostic scales: systematic literature review.

OBJECTIVE: To evaluate the predictive ability of mortality prediction scales in cancer patients admitted to intensive care units (ICUs). DESIGN: A systematic review of the literature was conducted using a search algorithm in October 2022. The following databases were searched: PubMed, Scopus, Virtual Health Library (BVS), and Medrxiv. The risk of bias was assessed using the QUADAS-2 scale. SETTING: ICUs admitting cancer patients. PARTICIPANTS: Studies that included adult patients with an active cancer diagnosis who were admitted to the ICU. INTERVENTIONS: Integrative study without interventions. MAIN VARIABLES OF INTEREST: Mortality prediction, standardized mortality, discrimination, and calibration. RESULTS: Seven mortality risk prediction models were analyzed in cancer patients in the ICU. Most models (APACHE II, APACHE IV, SOFA, SAPS-II, SAPS-III, and MPM II) underestimated mortality, while the ICMM overestimated it. The APACHE II had the SMR (Standardized Mortality Ratio) value closest to 1, suggesting a better prognostic ability compared to the other models. CONCLUSIONS: Predicting mortality in ICU cancer patients remains an intricate challenge due to the lack of a definitive superior model and the inherent limitations of available prediction tools. For evidence-based informed clinical decision-making, it is crucial to consider the healthcare team's familiarity with each tool and its inherent limitations. Developing novel instruments or conducting large-scale validation studies is essential to enhance prediction accuracy and optimize patient care in this population.

Clinical outcomes in patients with diabetes and stress hyperglycemia that developed SARS-CoV-2 infection / Desenlaces clínicos de los pacientes con diabetes e hiperglucemia de estrés que presentaron infección por SARS-CoV-2

INTRODUCTION: Diabetes and stress hyperglycemia have been related with poorer clinical outcomes in patients infected by SARS-CoV-2 and at risk for severe disease. OBJECTIVE: To evaluate clinical outcomes in three groups of patients (with diabetes, without diabetes and with stress hyperglycemia) with SARS-CoV-2 infection. MATERIALS AND METHODS: A retrospective cohort study was conducted in Cali (Colombia). We included patients 18 years old or older with a diagnosis of SARS-CoV-2 infection, managed in the emergency room, hospitalization, or intensive care unit between March 2020 and December 2021. Immunocompromised patients and pregnant women were excluded. Patients were classified into three groups: without diabetes, with diabetes, and with stress hyperglycemia. A comparison between the groups was performed. RESULTS: A total of 945 patients were included (59.6% without diabetes, 27% with diabetes, and 13.4% with stress hyperglycemia). Fifty-five-point three percent required intensive care unit management, with a higher need in patients with stress hyperglycemia (89.8%) and diabetes (67.1%), with no difference between these groups (p = 0.249). We identified a higher probability of death in the group with stress hyperglycemia versus the one without diabetes (adjusted OR = 8.12; 95% CI: 5.12-12.88; p < 0.01). Frequency of acute respiratory distress syndrome, need for invasive mechanical ventilation, use of vasopressors and inotropes, need for de novo renal replacement therapy, and mortality was higher in patients with metabolic alterations (diabetes and stress hyperglycemia). CONCLUSIONS: Diabetes and stress hyperglycemia were associated with worse clinical outcomes and mortality in patients with COVID-19. These patients should be identified early and considered them high risk at the COVID-19 diagnosis to mitigate adverse outcomes.

Introducción. La diabetes y la hiperglucemia de estrés se han relacionado con peores desenlaces clínicos en pacientes infectados por SARS-CoV-2 y con riesgo de enfermedad grave. Objetivo. Evaluar los resultados clínicos en tres grupos de pacientes (con diabetes, sin diabetes o con hiperglucemia de estrés) con infección por SARS-CoV-2. Materiales y métodos. Se llevó a cabo un estudio retrospectivo de cohorte en Cali (Colombia). Se incluyeron pacientes de 18 años o más, con diagnóstico de infección por SARS-CoV-2 atendidos en urgencias, hospitalización o unidad de cuidados intensivos entre marzo de 2020 y diciembre de 2021. Se excluyeron los pacientes inmunocomprometidos y las mujeres embarazadas. Los pacientes fueron clasificados en tres grupos: sin diabetes, con diabetes y con hiperglucemia de estrés. Se realizó una comparación entre los grupos. Resultados. Se incluyeron 945 pacientes (59,6 % sin diabetes, 27 % con diabetes y 13,4 % con hiperglucemia de estrés). El 55,3 % requirió manejo en la unidad de cuidados intensivos, con mayor necesidad por parte de los pacientes con hiperglucemia de estrés (89,8 %) y diabetes (67,1%), sin diferencia entre estos grupos (p = 0,249). Se observó una mayor probabilidad de muerte en el grupo con hiperglucemia de estrés versus sin diabetes (OR ajustado = 8,12; IC95%: 5,12-12,88; p < 0,01). La frecuencia de síndrome de distrés respiratorio agudo, necesidad de ventilación mecánica invasiva, uso de vasopresores e inotrópicos, necesidad de terapia de reemplazo renal de novo y mortalidad fue mayor en pacientes con alteraciones metabólicas (diabetes e hiperglucemia de estrés). Conclusiones. La diabetes y la hiperglucemia de estrés se asociaron a peores resultados clínicos y mortalidad en pacientes con COVID-19. Estos pacientes deben ser identificados tempranamente y considerados de alto riesgo al momento del diagnóstico de COVID-19 para mitigar los desenlaces adversos.

Pharmacotherapy assessment and adverse drug reactions in older patients admitted to intensive care.

INTRODUCTION: Older patients are more susceptible to medication use, and physiological changes resulting from aging and organic dysfunctions presented by critically ill patients may alter the pharmacokinetic or pharmacodynamic behavior. Thus, critically ill older people present greater vulnerability to the occurrence of pharmacotherapeutic problems. OBJECTIVE: To evaluate pharmacotherapy and the development of potential adverse drug reactions (ADRs) in older patients admitted to an intensive care unit (ICU). METHOD: A cohort study was conducted in an ICU for adults of a Brazilian University Hospital during a 12-month period. The patients' pharmacotherapy was evaluated daily, considering the occurrence of ADRs and drug-drug interactions (DDIs), the use of potentially inappropriate medications (PIMs) for older people, and the pharmacotherapy anticholinergic burden (ACB). A trigger tool was used for active search of ADRs, with subsequent causality evaluation. PIM use was evaluated by means of the Beers criteria and the STOPP/START criteria. The ABC scale was employed to estimate ACB. The Micromedex® and Drugs.com® medication databases were employed to evaluate the DDIs. RESULTS: The sample of this study consisted of 41 patients, with a mean age of 66.8 years old (±5.2). The 22 triggers used assisted in identifying 15 potential ADRs, and 26.8% of the patients developed them. The mean estimated ACB score was 3.0 (±1.8), and the patients used 3.1 (±1.4) and 3.3 (±1.6) PIMs according to the Beers and the STOPP criteria, respectively. A total of 672 DDIs were identified, with a mean of 16.8 (±9.5) DDIs/patient during ICU hospitalization. Our findings show an association between occurrence of ADRs in the ICU and polypharmacy (p=.03) and DDIs (p=.007), corroborating efforts for rational medication use as a preventive strategy. CONCLUSIONS: Using tools to evaluate the pharmacotherapy for older people in intensive care can assist in the recognition and prevention of pharmacotherapeutic problems, with emphasis on the identification of ADRs through the observation of triggers and subsequent causality analysis.

Work-related musculoskeletal complaints of physiotherapists working in intensive care units: Frequency analysis, risk factors, management and prevention strategies.

BACKGROUND: Intensive care physiotherapists are exposed to situations that may cause physical and mental overload, which can lead to the onset of work-related musculoskeletal complaints. OBJECTIVE: The objective was to analyze these complaints and to identify activities causing greater overload, factors associated with complaints, and management and prevention strategies. METHODS: Cross-sectional study. Data were collected from 125 physiotherapists in the Intensive Care units (ICU) of a tertiary hospital. The questionnaire used was formulated from questionnaires validated in the literature such as Nordic Questionnaire and Bork Questionnaire. Chi-square test was performed to compare the groups with and without complaints. Logistic regression was used to assess the association effects of the variables on the presence of complaints. RESULTS: Of those interviewed, 76% had a work-related complaint in the last year, with the "lower back" being the most affected region. Eighty percent had complaints for more than one site. "Transfer" was considered the activity causing the greatest overload. Female sex (p = 0.023), lack of physical activity (p = 0.028), inadequate ventilation (p = 0.001) and inadequate furniture (p = 0.006) showed a statistically significant association effect with the presence of complaints. Inadequate ventilation (p = 0.003) and female sex (p = 0.004) influenced the number of affected areas. Physical activity was considered the main strategy for prevention. CONCLUSION: Musculoskeletal complaints accounted for a high percentage of the analyzed sample, mainly in the lower back. The extent of complaints suggests that strategies should be developed and changes in work dynamics should be carried out.

INTRODUCTION: Intensive Care Units (ICUs) pose challenges in managing critically-ill patients with polypharmacy, potentially leading to Adverse Drug Reactions (ADRs), particularly in the elderly. OBJECTIVE: To evaluate whether the severity and clinical prognosis scores used in ICUs correlate with the prediction of ADRs in aged patients admitted to an ICU. METHODS: A cohort study was conducted in a Brazilian University Hospital ICU. APACHE II and SAPS 3 assessed clinical prognosis, while GerontoNet ADR Risk Score and BADRI evaluated ADR risk at ICU admission. Severity of the patients' clinical conditions was evaluated daily based on the SOFA score. Adverse Drug Reaction (ADR) screening was performed daily through the identification of ADR triggers. RESULTS: 1295 triggers were identified (median 30 per patient, IQR = 28), with 15 suspected ADRs. No correlation was observed between patient severity and ADRs at admission (p=0.26), during hospitalization (p=0.91), or at follow-up (p=0.77). There was also no association between death and ADRs (p=0.28) or worse prognosis and ADRs (p>0.05). Higher BADRI scores correlated with more ADRs (p=0.001). CONCLUSIONS: The data suggest that employing the severity and clinical prognosis scores used in Intensive Care Units is not sufficient to direct active pharmacovigilance efforts, which are therefore indicated for critically ill patients.

Patient-level cost analysis of intensive care unit acquired infections: A prospective cohort study.

INTRODUCTION: Hospital-associated infections (HAIs) are associated with increased mortality and prolonged hospital length-of-stay (LOS). Although some studies have shown that HAIs are associated with increased costs, these studies only used cost estimates, were carried out in a small number of centres, or only in high-income countries. METHODS: We carried out a prospective cohort study in ten Brazilian intensive care units (ICUs) selected from a collaborative platform study (IMPACTO MR). We included all patients aged 18 years or older admitted from October 2019 to December 2021 and who had an ICU LOS of at least two days. The costs were adjusted for official inflation until December 2022 and converted into international dollars using the 2021 purchasing power parity (PPP) conversion rate. We used a propensity score matching method to compare patients with HAIs and patients without HAIs, and patients with and without ventilator-associated pneumonia (VAP), central-line bloodstream infection (CLABSI), catheter-associated urinary tract infection (CA-UTI) and multidrug-resistant (MDR) HAIs. RESULTS: We included 7,953 patients in the study, of whom 574 (7.2%) had an HAI during their ICU stay. After propensity-score matching, patients with HAIs had ICU costs that were more than three times higher than those of patients without HAIs [$ 19,642 (IQR; 12,884-35,134) vs. 6,086 (IQR; 3,268-12,550); p <0.001). Patients with VAP, CLABSI, and CA-UTI, but not with MDR-HAIs also had higher total ICU costs. CONCLUSIONS: HAIs acquired in the ICU are associated with higher ICU costs. These findings were consistent across specific types of infection.

Development and Validation of the Companion's Satisfaction Questionnaire of Patient's Hospitalized in Intensive Care Units.

Objective: The current study aimed to develop and validate of companions' satisfaction questionnaire of patients hospitalized in ICUs. Methods: This is a methodological study that was performed in three phases: In the first phase, the concept of companion's satisfaction of patients hospitalized in ICUs was defined through qualitative content analysis method. In the second phase, early items of questionnaire were generated based on findings of the first phase. In the third and final phase, validation of the questionnaire was evaluated using face, content and construct validity as well as reliability. Results: In exploratory factor analysis, three subscales including: satisfaction with nursing staff communication (5 items), satisfaction with nursing care (12 items), and satisfaction with decision making (5 items) were extracted by Eigen value above one and factor load above 0.5. Internal consistency and stability of the developed questionnaire confirmed with 0.94 and 0.95 respectively that indicated acceptable reliability. Conclusion: The 22-item developed questionnaire is valid and reliable for measurement of levels of companion's satisfaction of Iranian patients hospitalized in ICUs.

The profile of patients with postpartum hemorrhage admitted to the obstetric intensive care: a cross-sectional study.

Objective: In Brazil, postpartum hemorrhage (PPH) is a major cause of maternal morbidity and mortality. Data on the profile of women and risk factors associated with PPH are sparse. This study aimed to describe the profile and management of patients with PPH, and the association of risk factors for PPH with severe maternal outcomes (SMO). Methods: A cross-sectional study was conducted in Instituto de Medicina Integral Prof. Fernando Figueira (IMIP) obstetric intensive care unit (ICU) between January 2012 and March 2020, including patients who gave birth at the hospital and that were admitted with PPH to the ICU. Results: The study included 358 patients, of whom 245 (68.4%) delivered in the IMIP maternity, and 113 (31.6%) in other maternity. The mean age of the patients was 26.7 years, with up to eight years of education (46.1%) and a mean of six prenatal care. Uterine atony (72.9%) was the most common cause, 1.6% estimated blood loss, 2% calculated shock index (SI), 63.9% of patients received hemotransfusion, and 27% underwent hysterectomy. 136 cases of SMO were identified, 35.5% were classified as maternal near miss and 3.0% maternal deaths. Multiparity was associated with SMO as an antepartum risk factor (RR=1.83, 95% CI1.42-2.36). Regarding intrapartum risk factors, abruptio placentae abruption was associated with SMO (RR=2.2 95% CI1.75-2.81). Among those who had hypertension (49.6%) there was a lower risk of developing SMO. Conclusion: The principal factors associated with poor maternal outcome were being multiparous and placental abruption.

Analysis of factors associated with mortality due to sepsis resulting from device-related infections.

INTRODUCTION: Health care-associated infections (HAIs) contribute to morbidity and mortality and to the dissemination of multidrug-resistant organisms. Children admitted to the intensive care unit undergo invasive procedures that increase their risk of developing HAIs and sepsis. The aim of the study was to analyse factors associated with mortality due to sepsis arising from HAIs. PATIENTS AND METHODS: We conducted a case-control study in a 7-bed multipurpose paediatric intensive care unit in a tertiary care teaching hospital. The sample consisted of 90 children admitted between January 2014 and December 2018. The case group consisted of patients who died from sepsis associated with the main health care-associated infections; the control group consisted of patients who survived sepsis associated with the same infections. RESULTS: Death was associated with age less than or equal to 12 months, presence of comorbidity, congenital disease, recurrent ventilator-associated pneumonia and septic shock. In the multiple regression analysis, heart disease (OR, 12.48; CI 2.55-60.93; P = .002), infection by carbapenem-resistant bacteria (OR, 31.51; CI 4.01-247.25; P = .001), cancer (OR, 58.23; CI 4.54-746.27; P = .002), and treatment with adrenaline (OR, 13.14; CI 1.35-128.02; P = .003) continued to be significantly associated with death. CONCLUSIONS: Hospital sepsis secondary to carbapenem-resistant bacteria contributed to a high mortality rate in this cohort. Children with heart disease or neoplasia or who needed vasopressor drugs had poorer outcomes.

Abstract Introduction: The control and evaluation of glycemic levels in critically ill patients is a challenge and a responsibility of the nursing team; therefore, determining the consequences of this during hospitalization is key to demonstrate the importance of timely management. Objective: To determine the relationship between unstable glycemia (hyperglycemia and hypoglycemia), hospital length of stay, and the hospitalization outcome of patients in an Intensive Care Unit (ICU). Methods: A prospective cohort study conducted with 62 critically ill patients by convenience sampling between March and July 2017. Daily blood samples were collected to measure glycemia. The correlation of unstable glycemia with the hospital length of stay and the hospitalization outcome was assessed using Pearson's chi-square. A p-value <0.05 was considered significant. Results: Among the 62 patients, 50% were male and 50% were female. The mean age was 63.3 years (±21.4 years). The incidence of unstable glycemia was 45.2% and was associated with a longer ICU stay (p<0.001) and a progression to death as a hospitalization outcome (p=0.03). Conclusion: Among critically ill patients, unstable glycemia was associated with an extended hospital length of stay and a progression to death, emphasizing the importance of nursing intervention to prevent its occurrence.

Cuidados respiratorios en pacientes con atrofia muscular espinal para evitar el fallo ventilatorio agudo y la traqueostomía: revisión literaria y recomendaciones consensuadas / Respiratory care in patients with spinal muscular atrophy to avoid acute ventilatory failure and tracheostomy: literature review and consensus recommendations

La atrofia muscular espinal (AME) 5q es una de las enfermedades neuromusculares de mayor incidencia en la infancia. Sin embargo, la prevalencia de AME tipo 1, su forma más severa de presentación, es menor debido a muertes prematuras evitables antes de los dos años por insuficiencia ventilatoria subtratada. La irrupción de nuevos tratamientos modificadores de la enfermedad pueden cambiar dramáticamente este pronóstico y es una oportunidad para actualizar el manejo respiratorio, a través de cuidados estandarizados básicos, preferentemente no invasivos, abordando la debilidad de los músculos respiratorios, la insuficiencia tusígena y ventilatoria, con un enfoque preventivo. La siguiente revisión literaria entrega estrategias para evitar la intubación y la traqueostomía usando soporte ventilatorio no invasivo (SVN), reclutamiento de volumen pulmonar (RVP) y facilitación de la tos. Se analizan en detalle los protocolos de extubación en niños con AME tipo 1.

Spinal muscular atrophy (SMA) 5q is one of the neuromuscular diseases with the highest incidence in childhood. Nevertheless, the prevalence of its most severe form SMA1 is lower due to premature preventable deaths before two years of age related to ventilatory insufficiency undertreated. The emergence of new disease-modifying treatments can dramatically change this prognosis and is an opportunity to update respiratory management, through basic standardized care, mostly non-invasive, addressing respiratory muscles pump weakness, cough and ventilatory insufficiency with a preventive approach. This literature review provides consensus recommendations for strategies to avoid intubation and tracheostomy using noninvasive ventilatory support (NVS), lung volume recruitment (LVR), and cough facilitation. Extubation protocols in children with SMA type 1 are analyzed in detail.
