Incidents related to patient safety are a problem of great impact in Intensive Care Medicine (ICM). Multiple strategies have been developed to identify them, analyze, and develop policies aim at reducing their incidence and minimizing their effects and consequences. The development of a safety culture, an adequate organizational and structural design of the ICM, which contemplates the implementation of effective safe practices, with a provision of human resources adjusted to the care activity carried out and the periodic analysis of the different events and their factors, will allow us to bring the risk of critical patient care closer to zero, as would be desirable.

Intermediate care units (IMCUs) have become increasingly important in the care of critical and semi-critical patients, particularly during the COVID-19 pandemic. However, there is still no clear definition of their structural characteristics, specialties, types of patients, and the benefits they provide. The aim of this work is to describe the current state of implementation and operation of IMCUs in hospitals and patient care. To achieve this goal, a systematic review was conducted in the Web of Science, Scopus and CINAHL databases, along with a hand search. The research yielded 419 documents, of which 26 were included in this review after applying inclusion and exclusion criteria. The results were highly diverse and were categorized based on the following topics: material resources, human resources, continuity of care, and patient benefits. Despite the different objectives outlined in the studies, all of them demonstrate the numerous benefits provided by an IMCU, along with the increased relevance of this type of unit in recent years. Therefore, this systematic review highlights the benefits of IMCUs in the care of critical patients, as well as the role of health workers in these units.

We present a rare case of large bilateral pleural effusion, pericardial effusion and pneumomediastinum caused by a peripherally inserted central catheter (PICC) line rupturing the left brachiocephalic vein, causing severe respiratory failure. The PICC line had been inserted with the aim of providing total parenteral nutrition (TPN). The patient developed symptoms within a day with effusions diagnosed on computer tomography pulmonary angiogram (CTPA). Bilateral pleural drains were inserted with a white milk-like substance drained consistent with TPN, prompting a further review of the CTPA revealing the mediastinal-positioned PICC line. The patient was transferred to the thoracic unit and was successfully managed with conservative measures. We propose some ideas such as the use of intracavitary electrocardiogram (IC-ECG) guidance as an adjuvant to obtain a correct and safe position.
CONCLUSIONS: PICC lines, although seen as safer, have potential for catastrophic adverse effects.The use of intracavitary electrocardiogram may be a safe adjunct and even an alternative to the use of a chest X-ray.Aspirating blood from all lumens with particular emphasis on the distal most lumen is very important.

This paper aims to support medical decision making on predicting the diagnosis of COVID-19. Thus, a set of Data Mining (DM) models was developed using prediction techniques and classification models. These models try to understand whether the vital signs of patients have a correlation with a diagnosis. To achieve the objective of the paper, initially, the data was acquired and collected from several data sources such as bedside monitors and electronic nursing records from the Intensive Care Unit of the Santo António Hospital. Secondly, the data was transformed so that it could be used in DM models. The models were induced using the following algorithms: Decision Trees, Random Forest, Naive Bayes, and Support Vector Machine. The analysis of the sensitivity, specificity, and accuracy were the metrics used to identify the most relevant measures to predict COVID-19 diagnosis. This work demonstrates that the models created had promising results.

The calcium sensitiser levosimendan, which is used as an inodilator to treat decompensated heart failure, may also exhibit anti-inflammatory properties. We examined whether treatment with levosimendan improves cardiopulmonary function and is substantially beneficial to the inflammatory response in acute respiratory response syndrome (ARDS). Levosimendan was administered intravenously in a new experimental porcine model of ARDS. For comparison, we used milrinone, another well-known inotropic agent. Our results demonstrated that levosimendan intravenously improved hemodynamics and lung function in a porcine ARDS model. Significant beneficial alterations in the inflammatory response and lung injury were not detected.

To analyze whether frailty can improve the prediction of mortality in patients admitted to the ICU after digestive surgery.
Prospective, observational, 6-month follow-up study of a cohort of patients admitted to the ICU between June 1, 2018, and June 1, 2019.
Surgical ICU of a third level hospital.
Series of successive patients older than 70 years who were admitted to the ICU immediately after a surgical intervention on the digestive system. 92 patients were included and 2 were excluded due to loss of follow-up at 6 months.
Upon admission to the ICU, severity and prognosis were assessed by APACHE II, and fragility by the Clinical Frailty Scale and the modified Frailty Index.
ICU, in-hospital and 6-month mortality.
The model that best predicts mortality in the ICU is the APACHE II, with an area under the ROC curve (AUC) of 0.89 and a good calibration. The model that combines APACHE II and Clinical Frailty Scale is the one that best predicts in-hospital mortality (AUC: 0.82), significantly improving the prediction of isolated APACHE II (AUC: 0.78; Integrated Discrimination Index: 0.04). Frailty is a predictor of mortality at 6 months, being the model that combines Clinical Frailty Scale and Frailty Index the one that has shown the greatest discrimination (AUC: 0.84).
Frailty can complement APACHE II by improving its prediction of hospital mortality. Furthermore, it offers a good prediction of mortality 6 months after surgery. For mortality in ICU, frailty loses its predictive power, whereas isolated APACHE II shows excellent predictive capacity.

OBJECTIVE: The adherence to hand hygiene practices among the adult Intensive Care Unit (ICU) professionals in this hospital has not improved substantially in the last years, regardless of the theoretical training sessions conducted. A study was made of the knowledge, attitudes, and practices of the ICU personnel in this field.
METHODS: Several small discussion groups with ICU staff organised by preventive medicine professionals were scheduled in March 2018. Semi-structured questions on hand hygiene and use of gloves were included. The points discussed were listed into strengths and weaknesses. Knowledge was then assessed using an anonymous questionnaire, after the sessions.
RESULTS: Thirteen 60-minute sessions were carried out with 157 participants from all professional categories (82% from ICU, median=11 participants / session). The majority perceived hand hygiene as a priority issue of personal responsibility for patient safety. They identified factors that limit their ability to improve their adherence. Certain habits have more to do with personal preferences than with theoretical knowledge or technical indications.
CONCLUSIONS: The discussion groups have helped to make a diagnosis of the situation that will be useful to strengthen those areas of improvement that have been identified. If we aim for a cultural change, and eliminate incorrect habits, it seems more useful to carry out adequate continuing education as part of the daily routine of professionals.

The Pan-American and Iberian Federation of Critical Medicine and Intensive Therapy, A.C. (FEPIMCTI), has prepared its Strategic Plan for the next 5 years. In this Plan, it defines its course towards the future, establishes its long-term objectives and works to achieve success. Its strategic objectives are framed in consolidating the legal, fiscal and administrative structure, the updating of its statutes, the implementation of a process management system encompassed in a quality culture, the implementation of committees of experts, achieving academic excellence by developing training programs and giving visibility to the Federation. Their main values refer to equity, professionalism, respect and social solidarity. The implementation of the Strategic Plan in a collaborative manner must serve as a driving force for change to position FEPIMCTI as a relevant Scientific Society in the Critical Medicine of its member countries.

BACKGROUND: The main aim of this study was to assess changes in the epidemiology and clinical presentation of Acinetobacter baumannii over a 10-year period, as well as risk factors of mortality in infected patients.
METHODS: Prospective, multicentre, hospital-based cohort studies including critically ill patients with A. baumannii isolated from any clinical sample were included. These were divided into a first period (\"2000 study\") (one month), and a second period (\"2010 study\") (two months). Molecular typing was performed by REP-PCR, PFGE and MSLT. The primary endpoint was 30-day mortality.
RESULTS: In 2000 and 2010, 103 and 108 patients were included, and the incidence of A. baumannii colonization/infection in the ICU decreased in 2010 (1.23 vs. 4.35 cases/1000 patient-days; p<0.0001). No differences were found in the colonization rates (44.3 vs. 38.6%) or infected patients (55.7 vs. 61.4%) in both periods. Overall, 30-day mortality was similar in both periods (29.1 vs. 27.8%). The rate of pneumonia increased from 46.2 in 2000 to 64.8% in 2010 (p<0.001). Performing MSLT, 18 different sequence types (ST) were identified (18 in 2000, 8 in 2010), but ST2 and ST79 were the predominant clones. ST2 isolates in the ICU increased from 53.4% in the year 2000 to 73.8% in 2010 (p=0.002). In patients with A. baumannii infection, the multivariate analysis identified appropriate antimicrobial therapy and ST79 clonal group as protective factors for mortality.
CONCLUSIONS: At 10 years of the first analysis, some variations have been observed in the epidemiology of A. baumannii in the ICU, with no changes in mortality. Epidemic ST79 clone seems to be associated with a better prognosis and adequate treatment is crucial in terms of survival.
