RESUMO

In Intensive Care Units (ICUs), patients are monitored using various devices that generate alerts when specific metrics, such as heart rate and oxygen saturation, exceed predetermined thresholds. However, these alerts can be inaccurate and lead to alert fatigue, resulting in errors and inaccurate diagnoses. We propose Alert grouping, a "Smart Personalization of Monitoring System Thresholds to Help Healthcare Teams Struggle Alarm Fatigue in Intensive Care" model. The alert grouping looks at patients at the individual and cluster levels, and healthcare-related constraints to assist medical and nursing teams in setting personalized alert thresholds of vital parameters. By simulating the function of ICU patient bed devices, we demonstrate that the proposed alert grouping model effectively reduces the number of alarms overall, improving the alert system's validity and reducing alarm fatigue. Implementing this personalized alert model in ICUs boosts medical and nursing teams' confidence in the alert system, leading to better care for ICU patients by significantly reducing alarm fatigue, thereby improving the quality of care for ICU patients.

RESUMO

OBJECTIVE: In a prospective multicenter study on adult patients with acute kidney injury (AKI) receiving enteral and/or parenteral nutrition, administered carbohydrates and lipids were compared to the prescribed amounts, as well as to substrate utilization data derived from indirect calorimetry measurements. METHODS: Resting energy expenditure (REE) was measured by indirect calorimetry. Nitrogen excretion was obtained from the protein catabolic rate calculated from urinary urea nitrogen when available and by urea kinetic-based methods in patients on renal replacement therapy. Fat and carbohydrate oxidations were derived from Frayn formulas. RESULTS: Ninety-two REE measurements were available in 35 critically ill patients with AKI (16 on renal replacement therapy). The mean lipid oxidation rate was 101 g/24 h (standard deviation [SD] 73.8), whereas prescribed lipids were 67 g/24 h (SD 32; P < .001). Carbohydrate utilization was derived from the same REE measurements yielding a mean carbohydrate oxidation of 105.8 g/24 h (SD 131.8), thus, much lower than the prescribed carbohydrates (186.7 g/24 h; SD 74.3; P < .001). The amount of fat and carbohydrates administered correlated to the prescribed amount (r = 0.896 and r = 0.829, respectively). Further analysis showed that this nutritional pattern was independent from the presence of sepsis. CONCLUSION: Our study suggests that critically ill patients with AKI do not receive an amount of carbohydrate and lipids adequate to support their needs on the basis of measured substrate utilization data. Thus, current nutritional approach in these patients, based on commercial formulas, should be challenged with measured substrate utilization-guided nutritional support.

RESUMO

Objectives: Therapeutic options available to treat MRSA pneumonia are limited. Trimethoprim/sulfamethoxazole is an attractive treatment because of its bactericidal anti-MRSA activity, oral and parenteral formulations and good penetration to the lung tissue. We aimed to compare the efficacy and safety of trimethoprim/sulfamethoxazole with vancomycin in the treatment of healthcare/ventilator-associated MRSA pneumonia. Methods: We carried out a retrospective case-control study of all consecutive hospitalized adult patients diagnosed with MRSA pneumonia at Beilinson Hospital during 2010-15 and treated with either vancomycin or trimethoprim/sulfamethoxazole. The primary outcomes were all-cause mortality at 30 days and clinical failure at the end of treatment. In order to reduce bias affecting the decision to use a specific antibiotic and as a sensitivity analysis, a propensity-score model for choosing between vancomycin and trimethoprim/sulfamethoxazole was used. Results: We identified 42 patients with MRSA pneumonia treated with trimethoprim/sulfamethoxazole and 39 treated with vancomycin. There were no significant differences in the baseline characteristics between the groups. Vancomycin-treated patients showed significantly higher 30 day mortality on both multivariate analysis (HR = 5.28; 95% CI = 1.50-18.60; P < 0.05) and sensitivity analysis with propensity score [vancomycin 13/24 (54.1%) versus trimethoprim/sulfamethoxazole 4/24 (16.7%); P < 0.05], and higher clinical failure rates [vancomycin 23/39 (59%) versus trimethoprim/sulfamethoxazole 15/42 (35.7%); P < 0.05], also in the sensitivity analysis with propensity score [vancomycin 14/24 (58.3%) versus trimethoprim/sulfamethoxazole 6/24 (25%); P < 0.05]. The rates of side effects in both arms were comparable. Conclusions: Trimethoprim/sulfamethoxazole appears to be superior to vancomycin in the treatment of MRSA pneumonia. A large-scale randomized controlled trial is needed to evaluate these findings.

RESUMO

PURPOSE: Vasopressin has become an important vasopressor drug while treating a critically ill patient to maintain adequate mean arterial pressure. Diabetes insipidus (DI) is a rare syndrome characterized by the excretion of a large volume of diluted urine, inappropriate for water homeostasis. We noticed that several COVID19 patients developed excessive polyuria suggestive of DI, with a concomitant plasma sodium-level increase and/or low urine osmolality. We noticed a temporal relationship between vasopressin treatment cessation and polyuria periods. We reviewed those cases to better describe this phenomenon. METHODS: We retrospectively collected COVID19 ECMO patients' (from July 6, 2020, to November 30, 2021) data from the electronic medical records. By examining urine output, urine osmolality (if applicable), plasma sodium level, and plasma osmolality, we set DI diagnosis. We described the clinical course of DI episodes and compared baseline characteristics between patients who developed DI and those who did not. RESULTS: Out of 37 patients, 12 had 18 episodes of DI. These patients were 7 years younger and had lower severity scores (APACHE-II and SOFA). Mortality difference was not seen between groups. 17 episodes occurred after vasopressin discontinuation; 14 episodes were treated with vasopressin reinstitution. DI lasted for a median of 21 h, with a median increase of 14 mEq/L of sodium. CONCLUSIONS: Temporary DI prevalence after vasopressin discontinuation in COVID19 ECMO patients might be higher than previously described for vasopressin-treated patients.

RESUMO

INTRODUCTION: Communication with ventilated patients in the Intensive care unit (ICU) is challenging. This may lead to anxiety and frustration, potentially contributing to the development of delirium. Various technologies, such as eye-tracking devices, have been employed to facilitate communication with varying grades of success. The EyeControl-Med device is a novel technology that delivers audio content and allows patients to interact by eye movements and could potentially allow for better communication in this setting. The aim of this exploratory concept study was to assess communication capabilities and delirium incidence using the EyeControl-Med device in critically ill patients unable to generate speech. MATERIAL AND METHODS: A single-arm pilot study of patients in a mixed ICU. Patients were approached for consent if they were invasively ventilated and/or tracheotomized, hence unable to generate speech, but had no severe cognitive or sensory impairment that could prevent proper usage. Patients underwent at least 3 sessions with the EyeControl-Med device administered by a speech-language pathologist. Communication and consciousness were assessed using the Loewenstein Communication Scale (LCS) tool during the first and last sessions. Delirium was assessed using a computerized CAM-ICU questionnaire. RESULTS: 15 patients were included, 40% of whom were diagnosed with COVID-19. All patients completed three to seven usage sessions. The mean LCS score improved by 19.3 points (p < 0.0001), with each of its five components showing significant improvements as well. The mean number of errors on the CAM-ICU questionnaire decreased from 6.5 to 2.5 (p = 0.0006), indicating a lower incidence of delirium. No adverse effects were observed. CONCLUSION: The EyeControl-Med device may facilitate communication and reduce the manifestations and duration of delirium in ventilated critically ill patients. Controlled studies are required to establish this effect.

RESUMO

INTRODUCTION: Hypophosphatemia may prolong ventilation and induce weaning failure. Some studies have associated hypophosphatemia with increased mortality. Starting or restarting nutrition in a critically ill patient may be associated with refeeding syndrome and hypophosphatemia. The correlation between nutrition, mechanical ventilation, and hypophosphatemia has not yet been fully elucidated. METHODS: A retrospective cohort study of 825 admissions during two consecutive years was conducted. Using the electronic medical chart, demographic and clinical data were obtained. Hypophosphatemia was defined as a phosphate level below 2.5 mg/dL (0.81 mmol/L) in the first 72 h of ICU admission. Comparisons between baseline characteristics and outcomes and multivariate analysis were performed. RESULTS: A total of 324 (39.27%) patients had hypophosphatemia during the first 72 h of ICU admission. Patients with hypophosphatemia tended to be younger, with lower APACHE-II, SOFA24, and ΔSOFA scores. They had a longer length of stay and length of ventilation, more prevalent prolonged ventilation, and decreased mortality. Their energy deficit was lower. There was no effect of hypophosphatemia severity on these results. In multivariate analysis, hypophosphatemia was not found to be statistically significant either with respect to mortality or survivor's length of ventilation, but lower average daily energy deficit and SOFA24 were found to be statistically significant with respect to survivor's length of ventilation. CONCLUSION: Hypophosphatemia had no effect on mortality or length of ventilation. Lower average daily energy deficit is associated with a longer survivor's length of ventilation.

RESUMO

INTRODUCTION: In patients suffering from disease-related and socioeconomic malnutrition and being discharged from hospital, continuity of care is challenging. Lack of adequate nutrition may lead to increase in morbidity and mortality. The aim of this study was to overcome the handicap of limited nutrition access in this category of patients and to study its consequences on clinical outcome. METHODS: Hospitalized patients screened to be at risk of malnutrition were approached and if diagnosed as suffering from malnutrition and from limited financial resources, they were randomized to receive a delivered daily dinner tray for 6 months and an assistance during the meal by a philanthropic association, or to regular food. At entry to the study, patients were assessed by indirect calorimetry, bioimpedance, Hospital Anxiety and Depression Scale (HADS), Functional independence measure (FIM) and SF 36 quality of life questionnaire. The latest questionnaires were reproduced after 3 and 6 months. Survival was followed at 6 months. The student t-test, the paired t-test, ANOVA were used. 180 days survival curves were expressed using the Kaplan-Meier method. RESULTS: 631 patients were screened and 60 patients were randomized. There was no difference between groups. Survival at 6 months was improved significantly in the intervention group (87%) compared to the control group (65%, p<005). HADS did significantly improve at 3 months and other parameters (FIM, SF 36) were not changed significantly. CONCLUSIONS: In hospitalized patients at nutritional risk, lunch home delivery, supported by a physical company after hospital discharge was associated with significantly lower mortality rates and improved depression and anxiety scores in elderly patients suffering from socioeconomic related malnutrition.

RESUMO

BACKGROUND: Quality of life (QOL) of home parenteral nutrition (HPN) patients is a critical issue for functioning and survival. This study evaluates the roles of sexual function (SF), self-efficacy (SE), and the use of social media (USM) in the QOL of HPN patients. MATERIALS AND METHODS: The study model investigates the independent variables USM and SF and the dependent variable QOL, and SE is a mediator variable between SF and USM. RESULTS: We included 203 participants with HPN who completed self-administered, validated questionnaires for QOL, SF, SE, and USM. Statistical analysis included a t-test, Sobel test, bootstrapping method, and Pearson correlations between variances. The mean HPN duration was 10.5 ± 8 years. Results show a significant correlation between QOL scores and SF (P = .001). USM was positively correlated with SE (P = .001). SE as a mediator between USM and SF was supported by significant results in the Sobel test. Patients with a stoma were significantly less sexually active and had lower SE ratings than those without a stoma. CONCLUSION: Physical changes that affect SE and boost social relationships by allowing emotional support through social networks are important factors for QOL improvement. These findings may guide health professionals in the management of HPN patients.

RESUMO

The optimal nutritional support in Acute Kidney Injury (AKI) still remains an open issue. The present study was aimed at evaluating the validity of conventional predictive formulas for the calculation of both energy expenditure and protein needs in critically ill patients with AKI. A prospective, multicenter, observational study was conducted on adult patients hospitalized with AKI in three different intensive care units (ICU). Nutrient needs were estimated by different methods: the Guidelines of the European Society of Parenteral and Enteral Nutrition (ESPEN) for both calories and proteins, the Harris-Benedict equation, the Penn-State and Faisy-Fagon equations for energy. Actual energy and protein needs were repeatedly measured by indirect calorimetry (IC) and protein catabolic rate (PCR) until oral nutrition start, hospital discharge or renal function recovery. Forty-two patients with AKI were enrolled, with 130 IC and 123 PCR measurements obtained over 654 days of artificial nutrition. No predictive formula was precise enough, and Bland-Altman plots wide limits of agreement for all equations highlight the potential to under- or overfeed individual patients. Conventional predictive formulas may frequently lead to incorrect energy and protein need estimation. In critically ill patients with AKI an increased risk for under- or overfeeding is likely when nutrient needs are estimated instead of measured.

RESUMO

BACKGROUND: Several reports suggest that stroke incidence is gradually declining, possibly owing to improvements in primary and secondary prevention. The objective of our study was to assess whether the trends of stroke hospitalization rates, common risk factors, and in-hospital outcomes affected both males and females similarly. METHODS: A retrospective review was made of discharge letters of acute ischemic stroke hospitalizations during 1988, 1996, and 2006 in a tertiary referral hospital. Data regarding demographics, common risk factors, and the in-hospital outcomes were collected. RESULTS: A total of 1,287 cases were recorded (mean age 68.7 ± 11.8 years, 53.3% males). The annual age-adjusted rates of stroke hospitalizations per 1,000 persons in 1988, 1996, and 2006 were 2.31, 1.64, and 1.64, respectively (p<0.001). The age-adjusted rates decreased in males (3.0, 1.77, and 1.67; p<0.001); there was no significant trend among females (1.68, 1.53, and 1.62; p = 0.864). The positive trends of age-adjusted rates of hypertension and dyslipidemia were significantly steeper in females than in males. No significant difference in the trends of adjusted in-hospital mortality rates between the sexes was found. Significant decline in the length of stay was demonstrated for both sexes, with no significant difference in the measure of decline between the groups. CONCLUSIONS: Stroke hospitalization rates decreased for men but not for women. Regardless of whether the discordance in stroke-incidence trends between males and females was caused by biological factors (different risk factor profile) or disparities in healthcare provision, it seems that the challenge of stroke prevention in the next decade is in lowering the risk of stroke in females.
