Medications to Modify Aspiration Risk: Those That Add to Risk and Those That May Reduce Risk.

Aspiration pneumonia results from the abnormal entry of fluids into the respiratory tract. We present a review of drugs known to affect the risk of aspiration. Drugs that increase the risk of aspiration pneumonia can be broadly divided into those that affect protective reflexes (like cough and swallowing) due to direct or indirect mechanisms, and drugs that facilitate gastric dysbiosis or affect esophageal and intestinal motility. Chief among the first group are benzodiazepines and antipsychotics, while proton pump inhibitors are the most well-studied in the latter group. Pill esophagitis may also exacerbate swallowing dysfunction. On the other hand, some research has also focused on pharmaceutical modulation of the risk of aspiration pneumonia. Angiotensin-converting enzyme inhibitors have been demonstrated to be associated with a decrease in the hazard of aspiration pneumonia in high-risk patients of Chinese or Japanese origin. Drugs like amantadine, nicergoline, or folic acid have shown some promising results in stroke patients, although the available evidence is thus far not enough to allow for any meaningful conclusions. Importantly, antimicrobial prophylaxis has been proven to be ineffective. Focusing on modifiable risk factors for aspiration pneumonia is relevant since this may help to reduce the incidence of this often severe problem. Among these, several commonly used drug classes have been shown to increase the risk of aspiration pneumonia. These drugs should be withheld in the high-risk population whenever possible, alongside general measures, such as the semirecumbent position during sleep and feeding.

The influenza landscape and vaccination coverage in older adults during the SARS-Cov-2 pandemic: data from Several European Countries and Israel.

INTRODUCTION: The Raise Awareness of Influenza Strategies in Europe (RAISE) group gathered information about the healthcare burden of influenza (hospitalizations, intensive care unit [ICU] admissions, and excess deaths), surveillance systems, and the vaccine coverage rate (VCR) in older adults in 18 European countries and Israel. AREAS COVERED: Published medical literature and official medical documentation on the influenza disease burden in the participating countries were reviewed from 2010/11 until the 2022/23 influenza seasons. Information on the framework for monitoring the disease burden and the provision for ensuring older adults had access to vaccination in their respective countries was provided. Data on influenza VCR in older adults were collected for the 2019/20 to 2022/23 influenza seasons. Data are reported descriptively. EXPERT OPINION: Influenza presents a significant healthcare burden in older adults. Reporting outcomes across participating countries is heterogeneous, highlighting the need for standardized approaches. Although older adults receive free influenza vaccination, vaccine uptake is highly variable among countries. Moreover, hospitalization rates remain high even in countries reporting a high VCR. Increased awareness and education on the burden of disease and the broader use of improved influenza vaccines for older adults may help reduce the disease burden on this population.

Epidemiology and Burden of Ventilator-Associated Pneumonia among Adult Intensive Care Unit Patients: A Portuguese, Multicenter, Retrospective Study (eVAP-PT Study).

Ventilator-associated pneumonia (VAP) is a prevailing nosocomial infection in critically ill patients requiring invasive mechanical ventilation (iMV). The impact of VAP is profound, adversely affecting patient outcomes and placing a significant burden on healthcare resources. This study assessed for the first time the contemporary VAP epidemiology in Portugal and its burden on the healthcare system and clinical outcomes. Additionally, resource consumption (duration of iMV, intensive care unit (ICU), hospital length of stay (LOS)) and empirical antimicrobial therapy were also evaluated. This multicenter, retrospective study included patients admitted to the hospital between July 2016 and December 2017 in a participating ICU, who underwent iMV for at least 48 h. Patients with a VAP diagnosis were segregated for further analysis (n = 197). Control patients, ventilated for >48 h but without a VAP diagnosis, were also included in a 1:1 ratio. Cumulative VAP incidence was computed. All-cause mortality was assessed at 28, 90, and 365 days after ICU admission. Cumulative VAP incidence was 9.2% (95% CI 8.0-10.5). The all-cause mortality rate in VAP patients was 24.9%, 34.0%, and 40.6%, respectively, and these values were similar to those observed in patients without VAP diagnosis. Further, patients with VAP had significantly longer ICU (27.5 vs. 11.0 days, p < 0.001) and hospital LOS (61 vs. 35.9 days, p < 0.001), more time under iMV (20.7 vs. 8.0 days, p < 0.001) and were more often subjected to tracheostomy (36.5 vs. 14.2%; p < 0.001). Patients with VAP who received inappropriate empirical antimicrobials had higher 28-day mortality, 34.3% vs. 19.5% (odds ratio 2.16, 95% CI 1.10-4.23), although the same was not independently associated with 1-year all-cause mortality (p = 0.107). This study described the VAP impact and burden on the Portuguese healthcare system, with approximately 9% of patients undergoing iMV for >48 h developing VAP, leading to increased resource consumption (longer ICU and hospital LOS). An unexpectedly high incidence of inappropriate, empirical antimicrobial therapy was also noted, being positively associated with a higher mortality risk of these patients. Knowledge of the Portuguese epidemiology characterization of VAP and its multidimensional impact is essential for efficient treatment and optimized long-term health outcomes of these patients.

Uncovering the burden of Influenza in children in Portugal, 2008-2018.

BACKGROUND: Despite their higher risk of developing severe disease, little is known about the burden of influenza in Portugal in children aged < 5 years old. This study aims to cover this gap by estimating the clinical and economic burden of severe influenza in children, in Portugal, during ten consecutive influenza seasons (2008/09-2017/18). METHODS: We reviewed hospitalizations in children aged < 5 years old using anonymized administrative data covering all public hospitals discharges in mainland Portugal. The burden of hospitalization and in-hospital mortality directly coded as due to influenza was supplemented by the indirect burden calculated from excess hospitalization and mortality (influenza-associated), estimated for four groups of diagnoses (pneumonia or influenza, respiratory, respiratory or cardiovascular, and all-cause), through cyclic regression models integrating the incidence of influenza. Means were reported excluding the H1N1pdm09 pandemic (2009/10). RESULTS: The mean annual number of hospitalizations coded as due to influenza was 189 (41.3 cases per 100,000 children aged < 5 years old). Hospitalization rates decreased with increasing age. Nine-in-ten children were previously healthy, but the presence of comorbidities increased with age. Children stayed, on average, 6.1 days at the hospital. Invasive mechanical ventilation was used in 2.4% of hospitalizations and non-invasive in 3.1%. Influenza-associated excess hospitalizations between 2008 and 2018 were estimated at 1,850 in pneumonia or influenza, 1,760 in respiratory, 1,787 in respiratory or cardiovascular, and 1,879 in all-cause models. A total of 95 influenza-associated excess deaths were estimated in all-cause, 14 in respiratory or cardiovascular, and 9 in respiratory models. Over ten years, influenza hospitalizations were estimated to have cost the National Health Service at least €2.9 million, of which 66.5% from healthy children. CONCLUSIONS: Influenza viruses led to a high number of hospitalizations in children. Most were previously healthy. Results should lead to a reflection on the adequate preventive measures to protect this age group.

European Network for ICU-Related Respiratory Infections (ENIRRIs): a multinational, prospective, cohort study of nosocomial LRTI.

PURPOSE: Lower respiratory tract infections (LRTI) are the most frequent infectious complication in patients admitted to the intensive care unit (ICU). We aim to report the clinical characteristics of ICU-admitted patients due to nosocomial LRTI and to describe their microbiology and clinical outcomes. METHODS: A prospective observational study was conducted in 13 countries over two continents from 9th May 2016 until 16th August 2019. Characteristics and outcomes of ventilator-associated pneumonia (VAP), ventilator-associated tracheobronchitis (VAT), ICU hospital-acquired pneumonia (ICU-HAP), HAP that required invasive ventilation (VHAP), and HAP in patients transferred to the ICU without invasive mechanical ventilation were collected. The clinical diagnosis and treatments were per clinical practice and not per protocol. Descriptive statistics were used to compare the study groups. RESULTS: 1060 patients with LRTI (72.5% male sex, median age 64 [50-74] years) were included in the study; 160 (15.1%) developed VAT, 556 (52.5%) VAP, 98 (9.2%) ICU-HAP, 152 (14.3%) HAP, and 94 (8.9%) VHAP. Patients with VHAP had higher serum procalcitonin (PCT) and Sequential Organ Failure Assessment (SOFA) scores. Patients with VAP or VHAP developed acute kidney injury, acute respiratory distress syndrome, multiple organ failure, or septic shock more often. One thousand eight patients had microbiological samples, and 711 (70.5%) had etiological microbiology identified. The most common microorganisms were Pseudomonas aeruginosa (18.4%) and Klebsiella spp (14.4%). In 382 patients (36%), the causative pathogen shows some antimicrobial resistance pattern. ICU, hospital and 28-day mortality were 30.8%, 37.5% and 27.5%, respectively. Patients with VHAP had the highest ICU, in-hospital and 28-day mortality rates. CONCLUSION: VHAP patients presented the highest mortality among those admitted to the ICU. Multidrug-resistant pathogens frequently cause nosocomial LRTI in this multinational cohort study.

Addressing influenza's underestimated burden - Iberian experts call to action.

Having a proper understanding of the impact of influenza is a fundamental step towards improved preventive action. This paper reviews findings from the Burden of Acute Respiratory Infections study on the burden of influenza in Iberia, and its potential underestimation, and proposes specific measures to lessen influenza's impact.

A multiple criteria approach for building a pandemic impact assessment composite indicator: The case of COVID-19 in Portugal.

The COVID-19 pandemic has caused major damage and disruption to social, economic, and health systems (among others). In addition, it has posed unprecedented challenges to public health and policy/decision-makers who have been responsible for designing and implementing measures to mitigate its strong negative impact. The Portuguese health authorities have used decision analysis techniques to assess the impact of the pandemic and implemented measures for counties, regions, or across the entire country. These decision tools have been subject to some criticism and many stakeholders requested novel approaches. In particular, those which considered the dynamic changes in the pandemic's behaviour due to new virus variants and vaccines. A multidisciplinary team formed by researchers from the COVID-19 Committee of Instituto Superior Técnico at the University of Lisbon (CCIST analyst team) and physicians from the Crisis Office of the Portuguese Medical Association (GCOM expert team) collaborated to create a new tool to help politicians and decision-makers to fight the pandemic. This paper presents the main steps that led to the building of a pandemic impact assessment composite indicator applied to the specific case of COVID-19 in Portugal. A multiple criteria approach based on an additive multi-attribute value theory aggregation model was used to build the pandemic assessment composite indicator. The parameters of the additive model were devised based on an interactive socio-technical and co-constructive process between the CCIST and GCOM team members. The deck of cards method was the adopted technical tool to assist in the assessment the value functions as well as in the assessment of the criteria weights. The final tool was presented at a press conference and had a powerful impact on the Portuguese media and on the main health decision-making stakeholders in the country. In this paper, a completed mathematical and graphical description of this tool is presented.

Ceftolozane/tazobactam for the treatment of Pseudomonas aeruginosa infections: A multicenter case series analysis.

INTRODUCTION: Pseudomonas aeruginosa displays resistance to several available antibiotics. Infections caused by this pathogen are associated with a high mortality, morbidity, and considerable healthcare resource utilization and costs. This study was aimed at describing the use of ceftolozane/tazobactam (C/T) for the treatment of patients with P. aeruginosa infections. METHODS: Case series analysis of hospitalized patients treated with C/T for P. aeruginosa infections in five public Portuguese hospitals. Patients presenting with infections caused by this pathogen and receiving C/T for at least 72h during hospitalization were eligible. RESULTS: Sixty-four hospitalized patients with P. aeruginosa infections treated with C/T were evaluated between December 2016 and July 2019. Most patients were aged between 60 and 79 years (53.9%). Patients presented a total of 68 P. aeruginosa infections, with respiratory infections being the most common (28.1%, 18 out of 64). Most P. aeruginosa strains (85.9%, 55 out of 64) were extensively drug-resistant (XDR). C/T was mostly used as targeted therapy (98.4%, 63 out of 64 patients) and as monotherapy (72.7%, 47 out of 64 patients). Combination therapy was used in 47.4% (9 out of 19) of patients with bacteriemia. Most patients had successful microbiological (79.2%, 42 out of 53) and clinical (78.7%, 48 out of 61) outcomes. All-cause in-hospital mortality rate was 34.4%. CONCLUSION: The present case series contributes to the body of evidence suggesting that C/T is an effective and safe option for treating P. aeruginosa infections, namely those caused by XDR strains, both when used as mono- or combination therapy.

Hospital-acquired pneumonia is more frequent and lethal in stroke patients: A nationwide 4-year study.

We report a higher incidence of hospital-acquired pneumonia (HAP) in patients admitted with stroke (odds ratio, 5.6; 95% CI, 5.4-5.8). Patients with HAP and stroke had an elevated risk of death (odds ratio, 1.2; 95% CI, 1.1-1.3). The incidence and mortality of HAP in stroke patients increased across all age groups.

Excess hospitalizations and mortality associated with seasonal influenza in Portugal, 2008-2018.

BACKGROUND: Influenza can have a domino effect, triggering severe conditions and leading to hospitalization or even death. Since influenza testing is not routinely performed, statistical modeling techniques are increasingly being used to estimate annual hospitalizations and deaths associated with influenza, to overcome the known underestimation from registers coded with influenza-specific diagnosis. The aim of this study was to estimate the clinical and economic burden of severe influenza in Portugal. METHODS: The study comprised ten epidemic seasons (2008/09-2017/18) and used two approaches: (i) a direct method of estimating the seasonal influenza hospitalization incidence, based on the number of National Health Service hospitalizations with influenza-specific International Classification of Diseases (ICD) codes (ICD-9: 487-488; ICD-10: J09-J11), as primary or secondary diagnosis; (ii) an indirect method of estimating excess hospitalizations and deaths using broader groups of ICD codes in time-series models, computed for six age groups and four groups of diagnoses: pneumonia or influenza (ICD-9: 480-488, 517.1; ICD-10: J09-J18), respiratory (ICD-9: 460-519; ICD-10: J00-J99), respiratory or cardiovascular (R&C, ICD-9: 390-459, 460-519; ICD-10: I00-I99, J00-J99), and all-cause. Means are reported excluding the H1N1pdm09 pandemic (2009/10). RESULTS: The mean number of hospitalizations coded as due to influenza per season was 1,207, resulting in 11.6 cases per 100,000 people. The mean direct annual cost of these hospitalizations was €3.9 million, of which 78.6% was generated by patients with comorbidities. Mean annual influenza-associated R&C hospitalizations were estimated at 5356 (min: 456; max: 8776), corresponding to 51.5 cases per 100,000 (95% CI: 40.9-62.0) for all age groups and 199.6 (95% CI: 163.9-235.8) for the population aged ≥ 65 years. The mean direct annual cost of the estimated excess R&C hospitalizations was €15.2 million for all age groups and €12.8 million for the population aged ≥ 65 years. Mean annual influenza-associated all-cause deaths per 100,000 people were estimated at 22.7 for all age groups. CONCLUSIONS: The study findings suggest that there is an under-detection of influenza in the Portuguese population. A high burden of severe influenza remains to be addressed, not only in the elderly population but also in younger people.

Prognostic value of hyperlactatemia in infected patients admitted to intensive care units: a multicenter study. / Valor prognóstico da hiperlactatemia em pacientes admitidos com infecção em unidades de terapia intensiva: estudo multicêntrico.

OBJECTIVE: To evaluate the influence of patient characteristics on hyperlactatemia in an infected population admitted to intensive care units and the influence of hyperlactatemia severity on hospital mortality. METHODS: A post hoc analysis of hyperlactatemia in the INFAUCI study, a national prospective, observational, multicenter study, was conducted in 14 Portuguese intensive care units. Infected patients admitted to intensive care units with a lactate measurement in the first 12 hours of admission were selected. Sepsis was identified according to the Sepsis-2 definition accepted at the time of data collection. The severity of hyperlactatemia was classified as mild (2 - 3.9mmol/L), moderate (4.0 - 9.9mmol/L) or severe (> 10mmol/L). RESULTS: In a total of 1,640 patients infected on admission, hyperlactatemia occurred in 934 patients (57%), classified as mild, moderate and severe in 57.0%, 34.4% and 8.7% of patients, respectively. The presence of hyperlactatemia and a higher degree of hyperlactatemia were both associated with a higher Simplified Acute Physiology Score II, a higher Charlson Comorbidity Index and the presence of septic shock. The lactate Receiver Operating Characteristic curve for hospital mortality had an area under the curve of 0.64 (95%CI 0.61 - 0.72), which increased to 0.71 (95%CI 0.68 - 0.74) when combined with Sequential Organ Failure Assessment score. In-hospital mortality with other covariates adjusted by Simplified Acute Physiology Score II was associated with moderate and severe hyperlactatemia, with odds ratio of 1.95 (95%CI 1.4 - 2.7; p < 0.001) and 4.54 (95%CI 2.4 - 8.5; p < 0.001), respectively. CONCLUSION: Blood lactate levels correlate independently with in-hospital mortality for moderate and severe degrees of hyperlactatemia.

OBJETIVO: Avaliar a influência das características dos pacientes na hiperlactatemia em uma população admitida com infecção em unidades de terapia intensiva, bem como a influência da gravidade da hiperlactatemia na mortalidade hospitalar. METÓDOS: Foi realizada uma análise post hoc da hiperlactatemia no INFAUCI, um estudo nacional prospectivo, observacional e multicêntrico, que incluiu 14 unidades de terapia intensiva portuguesas. Foram selecionados pacientes admitidos com infecção em unidades de terapia intensiva com dosagem de lactato nas primeiras 12 horas de admissão. A sepse foi identificada de acordo com a definição Sepsis-2 aceita no momento da coleta de dados. A gravidade da hiperlactatemia foi classificada como leve (2 - 3,9mmol/L), moderada (4,0 - 9,9mmol/L) ou grave (> 10mmol/L). RESULTADOS: De 1.640 pacientes admitidos com infecção, a hiperlactatemia ocorreu em 934 (57%) e foi classificada como leve, moderada e grave em 57,0%, 34,4% e 8,7% dos pacientes, respectivamente. A presença de hiperlactatemia e um maior grau de hiperlactatemia se associaram a um maior Simplified Acute Physiology Score II, a maior Índice de Comorbidade de Charlson e à presença de choque séptico. Em relação à curva Receiver Operating Characteristic do lactato para mortalidade hospitalar, foi encontrada área sob a curva de 0,64 (IC95% 0,61 - 0,72), que aumentou para 0,71 (IC95% 0,68 - 0,74) quando se combinou o Sequential Organ Failure Assessment. A mortalidade intra-hospitalar com outras covariáveis ajustadas pelo Simplified Acute Physiology Score II se associou à hiperlactatemia moderada e grave, com razão de chances de 1,95 (IC95% 1,4 - 2,7; p < 0,001) e 4,54 (IC95% 2,4 - 8,5; p < 0,001), respectivamente. CONCLUSÃO: Os níveis de lactato sanguíneo correlacionam-se independentemente com a mortalidade intra-hospitalar para graus moderados e graves de hiperlactatemia.

Update of the recommendations of the Sociedade Portuguesa de Cuidados Intensivos and the Infection and Sepsis Group for the approach to COVID-19 in Intensive Care Medicine. / Atualização das recomendações da Sociedade Portuguesa de Cuidados Intensivos e do Grupo de Infeção e Sépsis para a abordagem da COVID-19 em Medicina Intensiva.

INTRODUCTION: The Sociedade Portuguesa de Cuidados Intensivos and the Infection and Sepsis Group have previously issued health service and management recommendations for critically ill patients with COVID-19. Due to the evolution of knowledge, the panel of experts was again convened to review the current evidence and issue updated recommendations. METHODS: A national panel of experts who declared that they had no conflicts of interest regarding the development of the recommendations was assembled. Operational questions were developed based on the PICO methodology, and a rapid systematic review was conducted by consulting different bibliographic sources. The panel determined the direction and strength of the recommendations using two Delphi rounds, conducted in accordance with the principles of the GRADE system. A strong recommendation received the wording "is recommended", and a weak recommendation was written as "is suggested." RESULTS: A total of 48 recommendations and 30 suggestions were issued, covering the following topics: diagnosis of SARS-CoV-2 infection, coinfection and superinfection; criteria for admission, cure and suspension of isolation; organization of services; personal protective equipment; and respiratory support and other specific therapies (antivirals, immunomodulators and anticoagulation). CONCLUSION: These recommendations, specifically oriented to the Portuguese reality but that may also apply to Portuguese-speaking African countries and East Timor, aim to support health professionals in the management of critically ill patients with COVID-19. They will be continuously reviewed to reflect the progress of our understanding and the treatment of this pathology.

INTRODUÇÃO: A Sociedade Portuguesa de Cuidados Intensivos e o Grupo de Infeção e Sépsis emitiram previamente recomendações visando à organização dos serviços de saúde e ao manejo dos doentes críticos com COVID-19. Em virtude da evolução do conhecimento, o painel de peritos voltou a se organizar para rever a atual evidência e emitir recomendações atualizadas. MÉTODOS: Foi reunido um painel nacional de peritos que declararam não ter conflitos de interesse para o desenvolvimento das recomendações. Foram desenvolvidas perguntas operacionais conforme a metodologia PICO, e foi conduzida uma revisão sistemática rápida por meio da consulta de diferentes fontes bibliográficas. O painel determinou a direção e a força das recomendações com a utilização de duas rodadas de um método Delphi, conduzido seguindo princípios do sistema GRADE. Uma recomendação forte recebeu a redação "recomenda-se", e uma recomendação fraca foi redigida como "sugere-se". RESULTADOS: Foram emitidas 48 recomendações e 30 sugestões abrangendo os seguintes tópicos: diagnóstico de infecção por SARS-CoV-2, coinfecção e superinfecção; critérios de admissão, cura e suspensão de isolamento; organização dos serviços; Equipamentos de Proteção Individual; terapêuticas de suporte respiratório e outras e terapêuticas específicas (antivirais, imunomodeladores e anticoagulação). CONCLUSÃO: Essas recomendações, especificamente orientadas para a realidade portuguesa, mas que podem se aplicar também aos Países Africanos de Língua Oficial Portuguesa e ao Timor-Leste, visam apoiar os profissionais de saúde no manejo de doentes críticos com COVID-19. Pretende-se que sejam constantemente revistas, de modo a refletir o avanço de nossa compreensão e o da terapêutica dessa patologia.
