The advancement of critical care nursing as a response to the current demands.

The current demand on health services requires that nurses play a key role, by adapting their competencies to different fields and complexity levels. The approach of situations presented by critically ill patients underpins the need for development of specialised competencies in specific areas such as patient safety, prevention and control of healthcare-associated infections, performance of specific techniques and interventions, autonomous medication management or the use of technology, among others. Spain relies on a specialist training programme that is unique worldwide. Training admission is managed through a contract as a "Resident Nurse Intern" (EIR, Enfermera Interna Residente), provided by regional healthcare services. Only 6 specialities have been established and developed, in an uneven manner and with a short provision of places, annually. Given that the specialization in critical care nursing does not exist, nurses usually self-fund their postgraduate training to enhance their opportunities career development. The development of a speciality for critical care nursing is a priority. The models proposed advocate for creating nursing roles that could cover the systemic gaps through the expansion of their competencies and the introduction of procedures that fit nursing into advanced practice, which could be achieved through Advanced Accreditation Diplomas. Simultaneously, it would be convenient to analyse how and why such a dynamic discipline in some countries became stuck in anachronistic models of the Spanish healthcare system. This analysis might contribute to move forward on the development of areas of improvement in terms of service access and quality of care.

Impact of outdoor air pollution on severity and mortality in COVID-19 pneumonia.

The relationship between exposure to air pollution and the severity of coronavirus disease 2019 (COVID-19) pneumonia and other outcomes is poorly understood. Beyond age and comorbidity, risk factors for adverse outcomes including death have been poorly studied. The main objective of our study was to examine the relationship between exposure to outdoor air pollution and the risk of death in patients with COVID-19 pneumonia using individual-level data. The secondary objective was to investigate the impact of air pollutants on gas exchange and systemic inflammation in this disease. This cohort study included 1548 patients hospitalised for COVID-19 pneumonia between February and May 2020 in one of four hospitals. Local agencies supplied daily data on environmental air pollutants (PM10, PM2.5, O3, NO2, NO and NOX) and meteorological conditions (temperature and humidity) in the year before hospital admission (from January 2019 to December 2019). Daily exposure to pollution and meteorological conditions by individual postcode of residence was estimated using geospatial Bayesian generalised additive models. The influence of air pollution on pneumonia severity was studied using generalised additive models which included: age, sex, Charlson comorbidity index, hospital, average income, air temperature and humidity, and exposure to each pollutant. Additionally, generalised additive models were generated for exploring the effect of air pollution on C-reactive protein (CRP) level and SpO2/FiO2 at admission. According to our results, both risk of COVID-19 death and CRP level increased significantly with median exposure to PM10, NO2, NO and NOX, while higher exposure to NO2, NO and NOX was associated with lower SpO2/FiO2 ratios. In conclusion, after controlling for socioeconomic, demographic and health-related variables, we found evidence of a significant positive relationship between air pollution and mortality in patients hospitalised for COVID-19 pneumonia. Additionally, inflammation (CRP) and gas exchange (SpO2/FiO2) in these patients were significantly related to exposure to air pollution.

Immune treatment in COVID-19.

Current immune treatment directed to avoid viral replication relies mainly in convalescent plasma and monoclonal antibodies (mAbs). No clinical benefit for convalescent plasma has been reported in a meta-analysis and systematic review compared to standard of care. MAbs are recombinant proteins capable to bind with SARS-CoV-2 preventing its entrance into cells. Several mAbs have shown reduction in viral load and/or progression of the disease such as casirivimab-imdevimab, bamlanivimab-etesevimab and sotrovimab. After the apparition of Omicron variant, it has been reported that sotrovimab retained its activity whereas the other two combinations exhibited loss of neutralizing activity. Several aspects as the target population, timing and doses, serological patient status and evolution of variants still require attention, monitorization and further studies for knowledge gaps.

Recomendaciones para el manejo de los pacientes críticos con COVID-19 en las Unidades de Cuidados Intensivos / Recommendations for the management of critically ill patients with COVID-19 in Intensive Care Units

The COVID-19 pandemic has led to the admission of a high number of patients to the ICU, generally due to severe respiratory failure. Since the appearance of the first cases of SARS-CoV-2 infection, at the end of 2019, in China, a huge number of treatment recommendations for this entity have been published, not always supported by sufficient scientific evidence or with methodological rigor necessary. Thanks to the efforts of different groups of researchers, we currently have the results of clinical trials, and other types of studies, of higher quality. We consider it necessary to create a document that includes recommendations that collect this evidence regarding the diagnosis and treatment of COVID-19, but also aspects that other guidelines have not considered and that we consider essential in the management of critical patients with COVID-19. For this, a drafting committee has been created, made up of members of the SEMICYUC Working Groups more directly related to different specific aspects of the management of these patients (AU)

La pandemia por COVID-19 ha provocado el ingreso de un elevado número de pacientes en UCI, generalmente por insuficiencia respiratoria severa. Desde la aparición de los primeros casos de infección por SARS-CoV-2, a finales de 2019, en China, se ha publicado una cantidad ingente de recomendaciones de tratamiento de esta entidad, no siempre respaldadas por evidencia científica suficiente ni con el rigor metodológico necesario. Gracias al esfuerzo de distintos grupos de investigadores, actualmente disponemos de resultados de ensayos clínicos, y otro tipo de estudios, de mayor calidad. Consideramos necesario realizar un documento que incluya recomendaciones que recojan estas evidencias en cuanto al diagnóstico y el tratamiento de COVID-19, pero también aspectos que otras guías no han contemplado y que consideramos fundamentales en el manejo del paciente crítico con COVID-19. Para ello se ha creado un comité redactor, conformado por miembros de los Grupos de Trabajo de SEMICYUC más directamente relacionados con diferentes aspectos específicos del manejo de estos pacientes (AU)

Short-term neuropsychiatric outcomes and quality of life in COVID-19 survivors.

BACKGROUND: The general medical impacts of coronavirus (COVID-19) are increasingly appreciated. However, its impact on neurocognitive, psychiatric health and quality of life (QoL) in survivors after the acute phase is poorly understood. We aimed to evaluate neurocognitive function, psychiatric symptoms and QoL in COVID-19 survivors shortly after hospital discharge. METHODS: This was a cross-sectional analysis of a prospective study of hospitalized COVID-19 survivors followed up for 2 months after discharge. A battery of standardized instruments evaluating neurocognitive function, psychiatric morbidity and QoL (mental and physical components) was administered by telephone. RESULTS: Of the 229 screened patients, 179 were included in the final analysis. Amongst survivors, the prevalence of moderately impaired immediate verbal memory and learning was 38%, delayed verbal memory (11.8%), verbal fluency (34.6%) and working memory (executive function) (6.1%), respectively. Moreover, 58.7% of patients had neurocognitive impairment in at least one function. Rates of positive screening for anxiety, depression and post-traumatic stress disorder were 29.6%, 26.8% and 25.1%, respectively. In addition, 39.1% of the patients had psychiatric morbidity. Low QoL for physical and mental components was detected in 44.1% and 39.1% of patients respectively. Delirium and psychiatric morbidity were associated with neurocognitive impairment, and female gender was related with psychiatric morbidity. CONCLUSION: Hospitalized COVID-19 survivors showed a considerable prevalence of neurocognitive impairment, psychiatric morbidity and poor QoL in the short term. It is uncertain if these impacts persist over the long term.

Infection by the SARS-CoV-2 virus, known as COVID-19 (COronaVIrus Disease-19) was initially detected in China in December 2019, and has subsequently spread rapidly throughout the world, to the point that on March 11 the World Health Organization (WHO) reported that the outbreak could be defined as a pandemic. COVID-19 disease ranges from mild flu-like episodes to other serious and even life-threatening conditions, mainly due to acute respiratory failure. These patients are frequently admitted to our Intensive Care Units in relation to acute respiratory distress syndrome. The lack of a treatment based on scientific evidence has led to the use of different management guidelines, in many cases with rapid changes in the applied protocols. Recent reviews in reputed journals have underscored the lack of proven therapies and the need for clinical trials to establish clear and objective treatment guidelines. The present study provides an update on the currently applied treatment, and intends to offer help in relation to daily care, without seeking to replace the protocols adopted in each individual center.

On March 11, 2020, the Director-General of the World Health Organization (WHO) declared the disease caused by SARS-CoV-2 (COVID-19) as a pandemic. The spread and evolution of the pandemic is overwhelming the healthcare systems of dozens of countries and has led to a myriad of opinion papers, contingency plans, case series and emerging trials. Covering all this literature is complex. Briefly and synthetically, in line with the previous recommendations of the Working Groups, the Spanish Society of Intensive, Critical Medicine and Coronary Units (SEMICYUC) has prepared this series of basic recommendations for patient care in the context of the pandemic.

Bacterial etiology of community-acquired pneumonia in immunocompetent hospitalized patients and appropriateness of empirical treatment recommendations: an international point-prevalence study.

An accurate knowledge of the epidemiology of community-acquired pneumonia (CAP) is key for selecting appropriate antimicrobial treatments. Very few etiological studies assessed the appropriateness of empiric guideline recommendations at a multinational level. This study aims at the following: (i) describing the bacterial etiologic distribution of CAP and (ii) assessing the appropriateness of the empirical treatment recommendations by clinical practice guidelines (CPGs) for CAP in light of the bacterial pathogens diagnosed as causative agents of CAP. Secondary analysis of the GLIMP, a point-prevalence international study which enrolled adults hospitalized with CAP in 2015. The analysis was limited to immunocompetent patients tested for bacterial CAP agents within 24 h of admission. The CAP CPGs evaluated included the following: the 2007 and 2019 American Thoracic Society/Infectious Diseases Society of America (ATS/IDSA), the European Respiratory Society (ERS), and selected country-specific CPGs. Among 2564 patients enrolled, 35.3% had an identifiable pathogen. Streptococcus pneumoniae (8.2%) was the most frequently identified pathogen, followed by Pseudomonas aeruginosa (4.1%) and Klebsiella pneumoniae (3.4%). CPGs appropriately recommend covering more than 90% of all the potential pathogens causing CAP, with the exception of patients enrolled from Germany, Pakistan, and Croatia. The 2019 ATS/IDSA CPGs appropriately recommend covering 93.6% of the cases compared with 90.3% of the ERS CPGs (p < 0.01). S. pneumoniae remains the most common pathogen in patients hospitalized with CAP. Multinational CPG recommendations for patients with CAP seem to appropriately cover the most common pathogens and should be strongly encouraged for the management of CAP patients.

[Three keys to the appropriate choice of oral antibiotic treatment in the respiratory tract infections]. / Tres claves para seleccionar el antibiótico oral adecuado en las infecciones respiratorias.

Exacerbation of chronic obstructive pulmonary disease and community-acquired pneumonia are the most frequent infections of the lower respiratory tract in daily clinical practice. Antibiotic selection is a crucial component in its treatment and, in most cases, it is performed empirically. Scientific societies make therapeutic recommendations based on scientific evidence and / or expert recommendations that are of great help to clinicians. Beta-lactams, fluoroquinolones and macrolides are the most commonly used drugs for oral administration. From a practical point of view, there are three keys to the appropriate choice of oral antibiotic treatment, which are the effectiveness, safety and the ecological impact on the patient's microbiota, including the development of resistance, which will be assessed in depth in this review.

[Integral approach to the acute exacerbation of chronic obstructive pulmonary disease]. / Manejo integral del paciente con exacerbación aguda de la enfermedad pulmonar.

Chronic obstructive pulmonary disease is a set of clinical processes that have in common a chronic and progressive obstruction to airflow, with episodes of exacerbation. These exacerbations are more frequent and severe over time, deteriorating the lung function. The main cause of exacerbations is bacterial infection. There are multiple guidelines and documents that statement the management of this pathology. However, they focus primarily on the treatment during the stable phase. This document addresses the problem of acute exacerbation due to an infection from a multidisciplinary perspective, focusing on the integral approach to the process, and including etiology, microbiological studies, resistance to antimicrobials, risk stratification and initial empirical therapeutic management (antibiotic and concomitant). In addition, it includes an approach to more complex aspects such as the management of special populations (elderly and immunosuppressed) or therapeutic failure. Finally, more controversial topics such as prophylaxis of infection or palliative treatment are specifically discussed.

Red blood cell distribution width [RDW] and long-term mortality after community-acquired pneumonia. A comparison with proadrenomedullin.

Proadrenomedullin (proADM), a cardiovascular biomarker, has shown high prognostic power for community-acquired pneumonia (CAP) outcomes. Red-blood-cell distribution width (RDW), linked to cardiovascular disorders, has been associated with short-term and medium-term mortality after CAP. Our objective was to assess the accuracy of both biomarkers for CAP long-term mortality (>90 days). Adults hospitalized with CAP underwent blood proADM, RDW, C-reactive protein (CRP) and procalcitonin (PCT) measurements at admission, and were evaluated after 30, 90, and 180 days, and 1, 2, and 3 years, until either death or 5 years of follow-up. A group of 265 patients were recruited, with an average follow-up 1018 ± 539 days. Of these, 217 were followed for 1 year, and 187 for 3 years. Levels of both proADM and RDW were higher in those who died in the short term (p = 0.017 and p < 0.0001, respectively), medium term (p = 0.004 and p < 0.0001, respectively) and long term (p < 0.0001 and p < 0.0001, respectively). RDW showed lower accuracy (30-day AUC, 0.673) than proADM (AUC, 0.816), PSI (AUC, 0.846), and CURB65 (AUC, 0.817) scores for short-term and medium-term mortality prediction. However, accuracy was similar (3-year AUC, 0.692, 0.698, 0.743, and 0.704, respectively) for long-term mortality, and RDW > 14% (RDW > 14) increased the prediction power of both PSI (AUC, 0.743 vs 0.779; p < 0.0001) and CURB65 (AUC, 0.704 vs 0.747; p < 0.0001) scores, as did proADM. RDW > 14 + PSI and RDW > 14 + CURB65 associations had a sensitivity for long-term mortality of 80.8%-90% and 74%-90%, and a specificity of 56.7%-61.5% and 59.3%-64.2%, respectively. Both proADM and RDW > 14 (HR, 4.116) were independent risk factors for long-term mortality and were associated with poorer survival. Our findings agree with the suggested association between cardiovascular disease and long-term CAP mortality. RDW, routinely provided as part of the whole blood count, and especially associated with clinical scores, can provide useful information about long-term CAP outcomes.
