RESUMO

INTRODUCTION: Health care-associated infections (HAIs) contribute to morbidity and mortality and to the dissemination of multidrug-resistant organisms. Children admitted to the intensive care unit undergo invasive procedures that increase their risk of developing HAIs and sepsis. The aim of the study was to analyse factors associated with mortality due to sepsis arising from HAIs. PATIENTS AND METHODS: We conducted a case-control study in a 7-bed multipurpose paediatric intensive care unit in a tertiary care teaching hospital. The sample consisted of 90 children admitted between January 2014 and December 2018. The case group consisted of patients who died from sepsis associated with the main health care-associated infections; the control group consisted of patients who survived sepsis associated with the same infections. RESULTS: Death was associated with age less than or equal to 12 months, presence of comorbidity, congenital disease, recurrent ventilator-associated pneumonia and septic shock. In the multiple regression analysis, heart disease (OR, 12.48; CI 2.55-60.93; P = .002), infection by carbapenem-resistant bacteria (OR, 31.51; CI 4.01-247.25; P = .001), cancer (OR, 58.23; CI 4.54-746.27; P = .002), and treatment with adrenaline (OR, 13.14; CI 1.35-128.02; P = .003) continued to be significantly associated with death. CONCLUSIONS: Hospital sepsis secondary to carbapenem-resistant bacteria contributed to a high mortality rate in this cohort. Children with heart disease or neoplasia or who needed vasopressor drugs had poorer outcomes.

RESUMO

Ventilator-associated pneumonia (VAP) is one of the most common causes of nosocomial infections. The aim of this study was to evaluate the antimicrobial and anti-biofilm activity of an in-house low-cost tracheostomy tube impregnated with chlorhexidine and violet crystal. The impregnated tracheostomy tubes demonstrated antimicrobial activity, including for multidrug-resistant bacteria. Fourteen patients were evaluated. During ventilation, VAP occurred in one patient in the coated group and in three patients in the control group (p=0.28). A reduction of biofilm cells was observed. This study provides preliminary evidence to support that the antiseptic impregnation of a tracheostomy tube provides significant antimicrobial activity.

RESUMO

INTRODUCTION: Ventilator-associated pneumonia (VAP) presents a significant challenge in intensive care units (ICUs). Nebulized antibiotics, particularly colistin and tobramycin, are commonly prescribed for VAP patients. However, the appropriateness of using inhaled antibiotics for VAP remains a subject of debate among experts. This study aims to provide updated insights on the efficacy of adjunctive inhaled colistin and tobramycin through a comprehensive systematic review and meta-analysis. METHODS: A thorough search was conducted in MEDLINE, EMBASE, LILACS, COCHRANE Central, and clinical trials databases ( www. CLINICALTRIALS: gov ) from inception to June 2023. Randomized controlled trials (RCTs) meeting specific inclusion criteria were selected for analysis. These criteria included mechanically ventilated patients diagnosed with VAP, intervention with inhaled Colistin and Tobramycin compared to intravenous antibiotics, and reported outcomes such as clinical cure, microbiological eradication, mortality, or adverse events. RESULTS: The initial search yielded 106 records, from which only seven RCTs fulfilled the predefined inclusion criteria. The meta-analysis revealed a higher likelihood of achieving both clinical and microbiological cure in the groups receiving tobramycin or colistin compared to the control group. The relative risk (RR) for clinical cure was 1.23 (95% CI: 1.04, 1.45), and for microbiological cure, it was 1.64 (95% CI: 1.31, 2.06). However, there were no significant differences in mortality or the probability of adverse events between the groups. CONCLUSION: Adjunctive inhaled tobramycin or colistin may have a positive impact on the clinical and microbiological cure rates of VAP. However, the overall quality of evidence is low, indicating a high level of uncertainty. These findings underscore the need for further rigorous and well-designed studies to enhance the quality of evidence and provide more robust guidance for clinical decision-making in the management of VAP.

RESUMO

Introduction: Cervical spinal cord injury (CSCI) patients on mechanical ventilation often lack standardized guidelines for optimal ventilatory support. This study reviews existing literature to compare outcomes between high tidal volume (HTV) and low tidal volume (LTV) strategies in this unique patient population. Methods: We searched for studies published up to August 30, 2023, in five databases, following a PECO/PICO strategy. We found six studies for quantitative analysis and meta-analyzed five studies. Results: This meta-analysis included 396 patients with CSCI and mechanical ventilation (MV), 119 patients treated with high tidal volume (HTV), and 277 with low tidal volume (LTV). This first meta-analysis incorporates the few studies that show contradictory findings. Our meta-analysis shows that there is no significant statistical difference in developing VAP between both comparison groups (HTV vs. LTV) (OR 0.46; 95% CI 0.13 to 1.66; p > 0.05; I2: 0%), nor are there differences between the presence of other pulmonary complications when treating with HTV such as acute respiratory distress syndrome (ARDS), atelectasis, onset of weaning. Conclusion: In patients with CSCI in MV, the use of HTV does not carry a greater risk of pneumonia compared to LTV; in turn, it is shown as a safe ventilatory strategy as it does not establish an increase in other pulmonary complications such as ARDS, atelectasis, the onset of weaning nor others associated with volutrauma. It is necessary to evaluate the role of HTV ventilation in this group of patients in primary RCT-type studies.

RESUMO

Acinetobacter pneumonia is a significant healthcare-associated infection that poses a considerable challenge to clinicians due to its multidrug-resistant nature. Recent world events, such as the COVID-19 pandemic, have highlighted the need for effective treatment and management strategies for Acinetobacter pneumonia. In this review, we discuss lessons learned from recent world events, particularly the COVID-19 pandemic, in the context of the treatment and management of Acinetobacter pneumonia. We performed an extensive literature review to uncover studies and information pertinent to the topic. The COVID-19 pandemic underscored the importance of infection control measures in healthcare settings, including proper hand hygiene, isolation protocols, and personal protective equipment use, to prevent the spread of multidrug-resistant pathogens like Acinetobacter. Additionally, the pandemic highlighted the crucial role of antimicrobial stewardship programs in optimizing antibiotic use and curbing the emergence of resistance. Advances in diagnostic techniques, such as rapid molecular testing, have also proven valuable in identifying Acinetobacter infections promptly. Furthermore, due to the limited availability of antibiotics for treating infections caused A. baumannii, alternative strategies are needed like the use of antimicrobial peptides, bacteriophages and their enzymes, nanoparticles, photodynamic and chelate therapy. Recent world events, particularly the COVID-19 pandemic, have provided valuable insights into the treatment and management of Acinetobacter pneumonia. These lessons emphasize the significance of infection control, antimicrobial stewardship, and early diagnostics in combating this challenging infection.

RESUMO

Background and objective: The many patients who develop ventilator-associated pneumonia (VAP) have generated numerous VAP survivors who are not followed up in the long term. This study aimed, primarily, to evaluate the long-term functional capacity, as measured using the Glittre-ADL test (TGlittre), of VAP survivors and, secondarily, to calculate the correlations of TGlittre with muscle and lung function. Methods: This cross-sectional study evaluated 30 VAP survivors 10 months after discharge from the intensive care unit. The participants underwent the following assessments: TGlittre; respiratory muscle strength; handgrip strength (HGS); spirometry; Functional Assessment of Chronic Therapy (FACIT-F); and Short Form-36 (SF-36). Results: The median TGlittre time was 95 (81-130)% of predicted, and 30 % of the participants performed poorly on TGlittre. One-third of the participants had abnormal spirometry results. TGlittre time was correlated with weight (rs = -0.412, P = 0.023), body index mass (BMI, rs = -0.400, P = 0.029), forced vital capacity (FVC, rs = -0.401, P = 0.030), HGS (rs = -0.571, P = 0.0009), FACIT-F score (rs = -0.405, P = 0.026), and different SF-36 domain scores. Participants who returned to work had a shorter TGlittre time than those who did not (89 (69-104) vs. 129 (102-183)% predicted). Multiple linear regression indicated that FVC and BMI explained 39 % of TGlittre variability. Conclusion: VAP survivors had suboptimal functional capacity, low lung function, and general fatigue 10 months after discharge. The longer the TGlittre time was, the worse the lung function, muscle function, general fatigue, and quality of life were and the less likely the patient was to have returned to work.

RESUMO

Introducción: los pacientes con COVID-19 ingresan en mayor proporción a asistencia respiratoria mecánica, aumentando: el riesgo de neumonía asociada a ventilador (NAV) las tasas de mortalidad, los días de permanencia en las unidades de terapia intensiva (UCI) y los costos sanitarios. Objetivo: determinar la Mortalidad intrahospitalaria de pacientes con COVID-19 complicados con neumonías bacterianas en asistencia respiratoria mecánica en Cuidados Intensivos de Adultos en un Hospital del Paraguay durante los años 2020 a 2021. Metodología: estudio analítico de tipo cohorte retrospectiva. Se registraron variables demográficas, comorbilidades, puntajes en scores de gravedad como el APACHE II al ingreso, la cifra más baja de oxigenación durante la internación expresado por la PaO2 / FIO2, días de ventilación, colocación en decúbito prono, traqueotomía, medidas terapéuticas farmacológicas y no farmacológicas, días de internación, así como las complicaciones y la mortalidad. Resultados: fueron incluidos 214 pacientes, 135 ingresaron a asistencia respiratoria mecánica (ARM) de los cuales 58 (42,9 %) desarrollaron NAV, con edad mediana de 52 años (40-60). Los microorganismos de NAV fueron cocos Gram negativos en 98,3 %, incluyendo Acinetobacter baumanii en 46,5 %, Klebsiella pneumoniae en 22,8 %, Pseudomona aeruginosa en 15,5 % y 5,2 % Stenotrophomona maltofilia. La mortalidad intrahospitalaria fue del 44,8 %. Los menores de 50 años tienen una sobrevida mayor que los mayores (34 días vs 22 días, con p de 0,026). Conclusión: la mortalidad intrahospitalaria fue del 44,8 %. La edad fue un factor de riesgo independiente para la mortalidad en pacientes con NAV, por lo que los profesionales de la salud deben estar atentos a la posibilidad de NAV en pacientes que requieren asistencia respiratoria mecánica, especialmente en pacientes mayores de 50 años.

Introduction: patients with COVID-19 are more likely to require mechanical ventilation, which increases the risk of ventilator-associated pneumonia (VAP), mortality rates, length of stay in intensive care units (ICUs), and healthcare costs. Objective: to determine the in-hospital mortality of patients with COVID-19 complicated by bacterial pneumonia on mechanical ventilation in Adult Intensive Care in a Hospital in Paraguay during the years 2020 to 2021. Methodology: this is a retrospective cohort analytical study. Demographic variables, comorbidities, severity scores such as APACHE II on admission, the worst oxygenation during hospitalization expressed by PaO2/FiO2, days of ventilation, prone position, tracheostomy, pharmacological and non-pharmacological therapeutic measures, days of hospitalization, as well as complications and mortality were recorded. Results: a total of 214 patients were included, 135 were admitted to mechanical ventilation (MRA), of which 58 (42.9%) developed VAP, with a median age of 52 years (40-60). VAP microorganisms were Gram-negative cocci in 98.3%, including Acinetobacter baumanii in 46.5%, Klebsiella pneumoniae in 22.8%, Pseudomona aeruginosa in 15.5%, and Stenotrophomona maltophilia in 5.2%. In-hospital mortality was 44.8%. Those under 50 years of age have a longer survival than those older (34 days vs. 22 days, with p of 0.026). Conclusion: the overall mortality rate was 44.8%. Age was an independent risk factor for mortality in patients with VAP, so healthcare professionals should be aware of the possibility of VAP in patients who require mechanical ventilation, especially in patients over 50 years of age.

RESUMO

BACKGROUND: Healthcare-associated infections (HAIs) have a significant impact on patients' morbidity and mortality, and have a detrimental financial impact on the healthcare system. Various strategies exist to prevent HAIs, but economic evaluations are needed to determine which are most appropriate. AIM: To present the financial impact of a nationwide project on HAI prevention in intensive care units (ICUs) using a quality improvement (QI) approach. METHODS: A health economic evaluation assessed the financial results of the QI initiative 'Saúde em Nossas Mãos' (SNM), implemented in Brazil between January 2018 and December 2020. Among 116 participating institutions, 13 (11.2%) fully reported the aggregate cost and stratified patients (with vs without HAIs) in the pre-intervention and post-intervention periods. Average cost (AC) was calculated for each analysed HAI: central-line-associated bloodstream infections (CLABSIs), ventilator-associated pneumonia (VAP) and catheter-associated urinary tract infections (CAUTIs). The absorption model and time-driven activity-based costing were used for cost estimations. The numbers of infections that the project could have prevented during its implementation were estimated to demonstrate the financial impact of the SNM initiative. RESULTS: The aggregated ACs calculated for each HAI from these 13 ICUs - US$8480 for CLABSIs, US$10,039 for VAP, and US$7464 for CAUTIs - were extrapolated to the total number of HAIs prevented by the project (1727 CLABSIs, 3797 VAP and 2150 CAUTIs). The overall savings of the SNM as of December 2020 were estimated at US$68.8 million, with an estimated return on investment (ROI) of 765%. CONCLUSION: Reporting accurate financial data on HAI prevention strategies is still challenging in Brazil. These results suggest that a national QI initiative to prevent HAIs in critical care settings is a feasible and value-based approach, reducing financial waste and yielding a significant ROI for the healthcare system.

RESUMO

Lean healthcare visual management has been successfully integrated into infection control programs, leading to lower healthcare-associated infection (HAI) rates and greater provider compliance with evidence-based prevention practices; however, its implementation during quality improvement (QI) initiatives in limited-resource settings has not yet been well exploited. We aimed to describe a low-cost strategy involving Kamishibai cards to sustain bundles' adherence to prevent HAIs in a middle-income country. This descriptive case study evaluated the implementation of a lean healthcare visual management tool-Kamishibai board (K-board)-during a nationwide QI collaborative preventing three critical HAIs in 189 adult and pediatric/neonatal intensive care units (ICUs) from September 2021 to January 2023. Considering a limited-resource setting, our team adapted a K-board using simple, cheap, and easy-to-handle materials for routine monitoring of QI procedures, including safety bundles' compliance. After test prototypes, the final K-board version was implemented. The chart materials and assembly cost BRL 80.00 (USD 15.48). Before launching, expert working group meetings were held to shape the contents, refine technical issues, and prepare the ICU teams for implementation. After starting, plan-do-study-act cycles were conducted according to the Breakthrough Series model. Participating ICU teams, including leaders and front-line health workers, performed bedside audits following a weekly chronogram. Two indicators were calculated: the percentage of ICUs in which K-boards were being implemented and whether bundles' compliance was addressed in the K-board. Audit data were recorded in 'SimpleQI'. After 17 months of this initiative, 177 (93.7%) participating ICUs had included this visual management tool in their daily care routines. When more than 94 (>50%) ICUs posted K-board data, the mean compliance for the bundles for each HAI was sustained above 85%. A lean healthcare visual management tool can be adapted to local settings, including healthcare facilities with limited resources. K-board seems to be a feasible method for auditing evidence-based practices in medical care, including safety bundles to simultaneously prevent three types of HAIs.
