Cultivating global antimicrobial stewardship: linguistic and cultural validation of the Australian National Antimicrobial Prescribing Survey appropriateness assessment definitions for Portugal.

BACKGROUND: Antimicrobial resistance is driven by inappropriate antimicrobial prescribing. The National Antimicrobial Prescribing Survey (NAPS) is an Australian-developed auditing platform to assist in the assessments of antimicrobial quality by antimicrobial stewardship programmes using consensus-based definitions. The NAPS has demonstrated to be transferable to other countries. Its adaptation to Portugal could improve knowledge about the quality of antimicrobial prescribing in the country. OBJECTIVES: To translate, culturally adapt, and validate the Australian Hospital NAPS appropriateness assessment definitions of antimicrobial prescribing for Portugal. METHODS: International recommendations on translation and adaptation of instruments were followed. Two panels of experts participated in the process, using Zoom® for discussions and interviews, and Google Forms® for assessing vignettes. A native English-speaking person proficient in Portuguese conducted the back-translation. SPSS v.28 and Excel® were used for validity calculation. RESULTS: The Portuguese version was well accepted, its implementation being perceived as desirable and feasible by the experts. Validation process showed a Fleiss' κ score of 0.483 (95% CI, 0.415-0.551, P < 0.005) for appropriateness, and an average agreement with the Australian NAPS team of 0.8 and 0.9, respectively, for appropriateness and reasons for inappropriateness. CONCLUSIONS: The Portuguese version of the Australian Hospital NAPS appropriateness assessment definitions of antimicrobial prescribing, the first to be translated from English, was deemed non-inferior to the original, was well accepted, considered to be desirable and feasible, and could inspire other countries, particularly other Portuguese-speaking countries, to adapt and validate them in their own contexts, reinforcing the possibility of transferring NAPS use beyond Australia.

Influence of Deep Sedation in Intensive Care Medicine Memories of Critical COVID-19 Survivors.

Introduction: Critical care survivors sustain a variety of sequelae after intensive care medicine (ICM) admission, and the Coronavirus Disease 2019 (COVID-19) pandemic has added further challenges. Specifically, ICM memories play a significant role, and delusional memories are associated with poor outcomes post-discharge including a delayed return to work and sleep problems. Deep sedation has been associated with a greater risk of perceiving delusional memories, bringing a move toward lighter sedation. However, there are limited reports on post-ICM memories in COVID-19, and influence of deep sedation has not been fully defined. Therefore, we aimed to evaluate ICM-memory recall in COVID-19 survivors and their relation with deep sedation. Materials/Methods: Adult COVID-19 ICM survivors admitted to a Portuguese University Hospital between October 2020 and April 2021 (second/third "waves") were evaluated 1 to 2 months post-discharge using "ICU Memory Tool," to assess real, emotional, and delusional memories. Results: The study included 132 patients (67% male; median age = 62 years, Acute Physiology and Chronic Health Evaluation [APACHE]-II = 15, Simplified Acute Physiology Score [SAPS]-II = 35, ICM stay = 9 days). Approximately 42% received deep sedation (median duration = 19 days). Most participants reported real (87%) and emotional (77%) recalls, with lesser delusional memories (36.4%). Deeply sedated patients reported significantly fewer real memories (78.6% vs 93.4%, P = .012) and increased delusional memories (60.7% vs 18.4%, P < .001), with no difference in emotional memories (75% vs 80.4%, P = .468). In multivariate analysis, deep sedation had a significant, independent association with delusional memories, increasing their likelihood by a factor of approximately 6 (OR = 6.274; 95% confidence interval = 1.165-33.773, P = .032), without influencing real (P = .545) or emotional (P = .133) memories. Conclusions: This study contributes to a better understanding of the potential adverse effects of deep sedation on ICM memories in critical COVID-19 survivors, indicating a significant, independent association with the incidence of delusional recalls. Although further studies are needed to support these findings, they suggest that strategies targeted to minimize sedation should be favored, aiming to improve long-term recovery.

Hospital context in surgical site infection following colorectal surgery: a multi-level logistic regression analysis.

BACKGROUND: Surgical site infections (SSIs) are associated with poor health outcomes. Their incidence is highest after colorectal surgery, with little improvement in recent years. The role of hospital characteristics is undetermined. AIM: To investigate whether SSI incidence after colorectal surgery varies between hospitals, and whether such variance may be explained by hospital characteristics. METHODS: Data were retrieved from the electronic platform of the Directorate General of Health, from 2015 to 2019. Hospital characteristics were retrieved from publicly available data on the Portuguese public administration. Analysis considered a two-level hierarchical data structure, with individuals clustered in hospitals. To avoid overfitting, no models were built with more than one hospital characteristic. Cluster-level associations are presented through median odds ratio (MOR) and intraclass cluster coefficient (ICC). Beta coefficients were used to assess the contextual effects. FINDINGS: A total of 11,219 procedures from 18 hospitals were included. The incidence of SSI was 16.8%. The ICC for the null model was 0.09. Procedural variables explained 25% of the variance, and hospital dimension explained another 17%. More than 50% of SSI variance remains unaccounted for. After adjustment, heterogeneity between hospitals (MOR: 1.51; ICC: 0.05) was still found. No hospital characteristic was significantly associated with SSI. CONCLUSION: Procedural variables and hospital dimension explain almost half of SSI variance and should be taken into account when implementing prevention strategies. Future research should focus on compliance with preventive bundles and other process indicators in hospitals with significantly less SSI in colorectal surgery.

Entorno prehospitalario y manejo en UCI de epiglotitis en un adulto / Approaching the airway in prehospital emergency is a common and potentially life-saving practice

El abordaje de la vía aérea en la unidad de urgencias prehospitalarias es una práctica común que potencialmente salva vidas. El manejo es complejo debido al entorno, lo cual significa un porcentaje mucho más elevado de vías aéreas difíciles que en un ambiente regulado, como en el caso del quirófano.El intento fallido o prolongado de intubación traqueal está asociado a resultados desfavorables y complicaciones graves.La epiglotitis aguda es un trastorno potencialmente letal, clasificado como urgencia médica dentro de las enfermedades de la vía aérea respiratoria superior, que se caracteriza por una evolución repentina y mortal si no se logra una intubación rápida que permita la oxigenación del paciente.Describimos el caso de un paciente de 36 años con estridor, disnea e hipoxemia debido a la obstrucción total de la vía aérea, causada por una epiglotitis aguda. Nuestro objetivo es subrayar esta lesión infrecuente y su manejo desde la unidad prehospitalaria hasta el alta, ilustrando la gravedad de la presentación clínica, el tratamiento actual y el resultado.(AU)

Management by the environment is complex, which means a much higher percentage of difficult airways than in a regulated environment such as the operating room. Failure or prolonged attempt to tracheal intubation is associated with unfavorable outcomes and serious complications. Acute epiglottitis is a life-threatening disorder, classified as a medical emergency within the diseases of the upper respiratory airway and characterized by its sudden and deadly evolution if rapid intubation is not achieved to allow oxygenation of the patient. We describe a 36-year-old male patient with stridor, dyspnea e hypoxemia due to total obstruction of airway, caused by an acute epiglottitis. We aim to highlight this unusual injury and its management from the prehospital until discharge illustrating the severity of the clinical presentation, current treatment and outcome.(AU)

Impact of antibiotic therapy in severe community-acquired pneumonia: Data from the Infauci study.

Antibiotic therapy (AT) is the cornerstone of the management of severe community-acquired pneumonia (CAP). However, the best treatment strategy is far from being established. To evaluate the impact of different aspects of AT on the outcome of critically ill patients with CAP, we performed a post hoc analysis of all CAP patients enrolled in a prospective, observational, multicentre study. Of the 502 patients included, 76% received combination therapy, mainly a ß-lactam with a macrolide (80%). AT was inappropriate in 16% of all microbiologically documented CAP (n=177). Hospital and 6months mortality were 34% and 35%. In adjusted multivariate logistic regression analysis, combination AT with a macrolide was independently associated with a reduction in hospital (OR 0.17, 95%CI 0.06-0.51) and 6months (OR 0.21, 95%CI 0.07-0.57) mortality. Prolonged AT (>7days) was associated with a longer ICU (14 vs. 7days; p<0.001) and hospital length of stay (LOS) (25 vs. 17days; p<0.001). Combination AT with a macrolide may be the most suitable AT strategy to improve both short and long term outcome of severe CAP patients. AT >7days had no survival benefit and was associated with a longer LOS.

International ERS/ESICM/ESCMID/ALAT guidelines for the management of hospital-acquired pneumonia and ventilator-associated pneumonia

The most recent European guidelines and task force reports on hospital-acquired pneumonia (HAP) and ventilator-associated pneumonia (VAP) were published almost 10 years ago. Since then, further randomised clinical trials of HAP and VAP have been conducted and new information has become available. Studies of epidemiology, diagnosis, empiric treatment, response to treatment, new antibiotics or new forms of antibiotic administration and disease prevention have changed old paradigms. In addition, important differences between approaches in Europe and the USA have become apparent.The European Respiratory Society launched a project to develop new international guidelines for HAP and VAP. Other European societies, including the European Society of Intensive Care Medicine and the European Society of Clinical Microbiology and Infectious Diseases, were invited to participate and appointed their representatives. The Latin American Thoracic Association was also invited.A total of 15 experts and two methodologists made up the panel. Three experts from the USA were also invited (Michael S. Niederman, Marin Kollef and Richard Wunderink).Applying the GRADE (Grading of Recommendations, Assessment, Development and Evaluation) methodology, the panel selected seven PICO (population-intervention-comparison-outcome) questions that generated a series of recommendations for HAP/VAP diagnosis, treatment and prevention.(AU)

Drivers and impact of antifungal therapy in critically ill patients with Aspergillus-positive respiratory tract cultures.

Invasive pulmonary aspergillosis (IPA) is an increasingly recognised problem in critically ill patients. Little is known about how intensivists react to an Aspergillus-positive respiratory sample or the efficacy of antifungal therapy (AFT). This study aimed to identify drivers of AFT prescription and diagnostic workup in patients with Aspergillus isolation in respiratory specimens as well as the impact of AFT in these patients. ICU patients with an Aspergillus-positive respiratory sample from the database of a previous observational, multicentre study were analysed. Cases were classified as proven/putative IPA or Aspergillus colonisation. Demographic, microbiological, diagnostic and therapeutic data were collected. Outcome was recorded 12 weeks after Aspergillus isolation. Patients with putative/proven IPA were more likely to receive AFT than colonised patients (78.7% vs. 25.5%; P <0.001). Patients with host factors for invasive fungal disease were more likely to receive AFT (72.5% vs. 37.4%) as were those with multiorgan failure (SOFA score >7) (68.4% vs. 36.9%) (both P <0.001). Once adjusted for disease severity, initiation of AFT did not alter the odds of survival (HR = 1.40, 95% CI 0.89-2.21). Likewise, treatment within 48 h following diagnosis did not change the clinical outcome (75.7% vs. 61.4%; P = 0.63). Treatment decisions appear to be based on diagnostic criteria and underlying disease severity at the time of Aspergillus isolation. IPA in this population has a dire prognosis and AFT is not associated with reduced mortality. This may be explained by delayed diagnosis and an often inevitable death due to advanced multiorgan failure.
