ABSTRACT

Hospital-acquired infections (HAIs) are a major contributor to death, morbidity, diminished quality of life, and growing healthcare expenditures. To protect patient health, it is crucial to reduce the risk of HAI by organising and putting into practice efficient preventative measures. The most important method of infection prevention generally agreed upon is hand cleanliness. Washing your hands can keep you healthy and stop the transmission of many respiratory and diarrheal illnesses. On any given day, 1 in 31 hospital patients develops an HAI while being treated. Hand hygiene is the simplest and effective method for the prevention of these. This study aimed to assess the hand-hygiene compliance among health care workers at GMC Anantnag and associated hospitals. A cross-sectional observational study was carried out among HCWs and 313 opportunities were observed using WHO tool for hand hygiene according to WHO “5 moments of hand hygiene.” The sampling technique adopted for selection of sample was non-probability convenience sampling. Out of total 244 opportunities of nurses, 181 (74%) had non-hand hygienic actions while 63 (26%) had hand hygienic actions. Out of total 59 opportunities of doctors, 29 (49%) had non-hand hygienic actions while 30 (51%) had hand hygienic actions. Out of total 10 opportunities of nursing aides, 9 (90%) had non-hand hygienic actions while 1 (10%) had hygienic actions. The overall hand hygienic observed among health care workers as per WHO Guidelines was 30 percent only. Nurses had an adherence rate of 26 percent, doctors 51 percent and nursing aids had 10 percent only. The present study showed low levels of adherence to best hygiene practices with overall compliance of 30 percent revealing that there is need to implement immediate strategies for infection control at GMC Anantnag and associated hospital.

ABSTRACT

Aims: Bacteria isolated from hospitalized patients are often responsible for healthcare-associated infections (HAI), particularly in developing countries. Thus, this study aimed to determine the antibiotic resistance profiles of bacteria isolated from patients hospitalized at the Sylvanus Olympio University Teaching Hospital (CHUSO) in Lomé, Togo. Study Design: This was a descriptive cross-sectional study carried out on laboratory data collected from January 1, 2018, to December 31, 2019. Methodology: The Kirby-Bauer disc diffusion method was used for antibiotic susceptibility testing and the results were interpreted according to the guidelines of the Antibiogram Committee of the French Society of Microbiology (CA-SFM, 2018). Results: A total of 639 samples were collected, including mainly pus (n = 339; 53.1%) and urine (n = 260; 40.7%). The samples were mainly from pediatrics (n=107; 16.7%), intensive care units (n=73; 11.4%) and surgical emergencies (n=72; 11.3%). A total of 698 bacteria were isolated, including mainly Escherichia coli (n=247, 35.4%), Staphylococcus aureus (n=123, 17.6%), and Klebsiella pneumoniae (n=114, 16.3%). Enterobacteriaceae strains were resistant to almost all antibiotics tested, except amikacin and ertapenem, which had respective resistance rates of 2.8% and 8.4%. None of the P. aeruginosa strains were resistant to piperacillin-tazobactam. whereas 37.9% were resistant to imipenem. Among A. baumannii strains, 4.2% and 22.9% were respectively resistant to amikacin and imipenem, whereas 56.3% were resistant to levofloxacin. Almost all S. aureus strains (99.2%) were resistant to penicillin, whereas only 2.4% were resistant to rifampicin. Of the 698 bacteria isolated, the prevalence of multidrug-resistant bacteria (MDR) was 41.3% (n = 288), whereas the prevalence of ESBL-producing Enterobacteriaceae was 51.3% (201/392). Conclusion: We reported various resistance profiles of bacterial species isolated from hospitalized patients at the CHU Sylvanus Olympio, Lomé, Togo. The study of bacterial ecology and resistance in every prefectural, regional, and university teaching hospital would be of great importance to reduce mortality associated with hospital-acquired infections throughout the Togolese territory.

ABSTRACT

Background: The prevalence of acute kidney injury (AKI) progressively increases with age. A higher rate of dialysis dependency and mortality is observed in elderly with AKI. Here we have studied the comparison of clinical features, outcomes of AKI between elderly (age � years) and non-elderly AKI patients and their risk factors for mortality. Methods: This prospective observational study enrolled 100 patients with AKI, with elderly and non-elderly in a 1:1 ratio for comparison, from September 2021 to January 2023 at AIIMS Rishikesh in India. Detailed history, clinical examination, relevant laboratory and radiological investigations were done to evaluate for the cause of AKI. Etiological causes, complications of AKI, and in-hospital outcomes were observed. They were given standard treatment and dialysis as per standard indications. We analysed the mortality risk of these groups using the Cox proportional hazards model. Results: The in-hospital mortality rates among these two groups were non-significant (p=0.29). A significantly higher number of patients with non-elderly AKI were HD-dependent at discharge (p=0.027). Elderly patients had significantly lesser complications like uremic encephalopathy and fluid overload compared to non-elderly. There was a significant association between mortality and female gender, intensive care unit (ICU) admissions, hospital-acquired AKI, pre-renal/renal causes, chronic obstructive pulmonary disease (COPD) as comorbidity, multiple organ dysfunction syndrome (MODS), mechanical ventilation requirement, vasopressor support requirement, need for hemodialysis and prolonged ICU stay. Conclusions: Elderly patients with AKI do not experience worse mortality outcomes than non-elderly patients with AKI. Therefore, elderly patients should not be denied timely treatment, solely based on their age.

ABSTRACT

Background: Hospital acquired infections, are a leading cause of mortality and morbidity. Ventilator associated pneumonia, one of the hospital acquired illnesses. The purpose of this study was to evaluate the prevalence, risk factors, causative organism, and antibiotic usage for the treatment of ventilator-associated pneumonia. Methods: Between May 2022 and October 2022, 50 patients participated in an ambispective and observational study conducted across several ICU departments at Adichunchanagiri Hospital, BG Nagara, Karnataka. Reviewing and evaluating daily patient case sheets, laboratory results, and treatment charts of participants who were hospital inpatients provided pertinent data needed for the study. Volunteers were enrolled after taking consent from each of them, a suitably designed data collection form was used to collect all the necessary information. Microsoft Excel was used to enter the data. Version 28 of SPSS was used to analyze the data. Statistical significance was determined by using a P-value of less than 0.05. Results: The study included 50 patients and discovered a 60% prevalence of ventilator-associated pneumonia in the general community. Staphylococcus aureus accounted for 26.7% of all gram-positive bacteria, whereas Enterobacter and Klebsiella species accounted for 16.7%. Metronidazole was given in 64% of instances, with accidents being the most frequent risk factor (40%). Conclusions: Within the specified population, the incidence of ventilator-associated pneumonia is 60%, with Staphylococcus aureus identified as the most predominant bacterial pathogen. Metronidazole is the most frequently prescribed antibiotic, and accidents are the key risk factors that cause ventilator-associated pneumonia.

ABSTRACT

Background: Antibiotics resistance is an paramount threat affecting the whole world but nowhere situation is as gloomy as in India. No study till date regarding epidemiology of hospital acquired infections in coronary care units(CCU) and cardiology wards from India. From Indian perspective it is the first observational study to analyse microbiological profile and antibiotic resistance in CCU.The purpose of this observational study is to explore the epidemiology and importance of infections in CCU patients. Methodology: After ethics committee approval, the records of all patients who were admitted in coronary care units, adult and pediatric cardiology wards surgery between January 2020 and December 2021 were reviewed retrospectively. The type of organism,source of infection ,age wise distribution and seasonal variability among patients who developed hospital acquired infection (HAI) were determined. Results: 271 patients developed microbiologically documented HAI during from January 2020 to December 2021. Maximum number of organisms(78/271 28.78%) are isolated from urinary samples ,followed by blood stream(60/271 22.14%) and Endotracheal tube (54/271 19.92%). Acinetobacter baumanii (53/271, 19.5%) being the most common isolate among all the samples taken .Acinetobacter was the most frequent pathogens isolated in patients with LRTI and blood stream infection while E.coli was from urinary tract infection . In the adult population, infection with E. coli(24.6%) is the most common followed by Klebsiella pneumoniae (12.8%) and Acinetobacter baumanii (10.1%). In the pediatric population Acinetobacter baumanii (38.6%%) is the most common followed by Klebsiella pneumoniae (20.5%) and Methicillin Resistant Staphylococcus aureus, MRSA (6.8%).Commonly used antibiotics eg ciprofloxacin,ceftazidime and amikacin were found to be resistant against the top three isolates. Conclusion: Urinary tract was the most common site of infection and Gram?negative bacilli, the most common pathogens in adult as well as pediatric population. Antibiotic resistance was maximum with commonly isolated microorganisms.

ABSTRACT

Background: The lower respiratory tract infections (LRTIs), including pneumonia, are the fourth most common cause of mortality globally and the second most frequent reason for years of life lost. India is home to one-quarter of the world’s pneumonia cases. Aims and Objectives: The present study was aimed to evaluate the clinical, bacteriological and radiological profile of CAP, HAP and VAP patients from a tertiary care teaching hospital. Material & Methods: This cross-sectional, observational study was conducted at the Department of Pulmonary Medicine, Bharati Vidyapeeth (DTU) Medical College and Hospital, Pune, India. The study included 100 clinically diagnosed patients of community-acquired pneumonia (CAP), hospital-acquired pneumonia (HAP), and ventilator-associated pneumonia (VAP). Patients were evaluated for clinical symptoms, microbiological investigations, radiological assessment, treatment given, and final outcome. Severity indices were calculated for CAP, HAP, and VAP patients to predict the severity and rate of mortality. Results: The most common symptoms are cough, fever, and shortness of breath. The most common organisms isolated in sputum cultures of patients with pneumonia are Streptococcus, Pseudomonas, and Acinetobacter. The most common site of consolidation on chest X-ray is bilateral. Mortality rates are highest in patients with ventilator-associated pneumonia (VAP), followed by hospital-acquired pneumonia (HAP) and community-acquired pneumonia (CAP). Conclusion: The most common symptoms of pneumonia are cough, fever, crepitation, and expectoration. Mortality rates are highest in patients with VAP, followed by HAP and CAP.

ABSTRACT

【Objective】 To analyze the effect of extensively hydrolyzed formula(eHF) in the treatment of feeding intolerance in preterm infants and the effect on hospital infection, in order to provide reference for the clinical treatment of feeding intolerance in preterm infants. 【Methods】 A total of 208 cases of preterm infants with feeding intolerance diagnosed and treated in Shandong Heze Municipal Hospital from April 2017 to February 2020 were selected into the clinical trial for eligibility assessment, then were randomly assigned into study group(n=100) and control group(n=100) after screening and exclusion. Children in the control group were fed with standard preterm formula, while children in the study group were fed with eHF. Feeding tolerance indicators, including daily milk intake, time to meconium evacuation, time to full gastrointestinal nutrition, total gastric residual counts(GRV1) in the 7-d period after resumption of breastfeeding, ratio of all-day gastric residual counts/all-day estimated milk intake after resumption of breastfeeding(GRV2) were compared between the two groups, and growth indicators(body weight growth rate, head dimension growth rate), complication incidence [necrotizing enterocolitis(NEC), pathological jaundice, positive fecal occult blood or blood in stool] and incidence of hospital-acquired infections. 【Results】 The daily milk intake(t=5.037) of the study group was higher than that of the control group, and the time of foetal excretion(t=9.217), the time to reach full gastrointestinal nutrition(t=15.833), GRV1(t=6.737), GRV2(t=9.956) were lower than those of the control group, and the differences were all statistically significant(P<0.05). The rate of weight gain(t=2.454) and head dimension growth(t=5.469) in the study group was significantly higher than those of the control group(P<0.05). The incidence of the three complications of NEC, pathological jaundice and positive fecal occult blood or blood in stool(χ2=4.310) and the incidence of hospital infections(χ2=4.688) were significantly lower in the study group than in the control group(P<0.05). 【Conclusions】 Compared with the standard formula milk for preterm infants, eHF can significantly improve the feeding intolerance of preterm infants, promote growth and development, and reduce the occurrence of hospital-acquired infections. Therefore, eHF can be widely used in clinic for preterm infants with feeding intolerance.

ABSTRACT

Background: This study measured the impact of the first and second wave of COVID-19 pandemic (in the year 2020-21) on the antibiotics uses and their effect on gram nehative bacterial species Klebsiella, Enterobacter, Pseudomonas and Acinetobacter. Methods: The number of patient admission month-wise, antibiotic consumption, blood cultures collected, number of positive BCs, and antibiotic resistance were analysed retrospectively for the years 2020, 2021, and 2019 for comparison, in tertiary care hospital (ca. 840 beds). Results: Half of patients admitted in years 2020 and 2021 in our hospital had COVID-19. A significant increase in total antibiotic consumption during the years 2020 (75.53 DDD per 100 admissions) and 2021 (91.71 DDD per 100 admissions) occurred in comparison to the year 2019 (52.5 DDD per 100 admissions). The rate ratio of BCs per 100 admissions increased by 74% in the year 2020, and 118% in the year 2021 in comparison with the rate ratio to the year 2019. The BSI rate per 100 admissions increased overall by 24% in March 2020 and 115% in April 2020, the rate ratio of BSIs per 100 admissions raised 58.4% for Klebsiella and 239.3% for E. coli, but remain the same for Acinetobacter and Aeruginosa. A sharp increase in the rate of BSIs caused by microorganisms resistant to cephalosporins was also observed in the years 2020 and 2021. Conclusions: present study highlights the impact of the first and second waves of the COVID-19 pandemic on antibiotic consumption and the increasing prevalence hospital-acquired infections and antimicrobial resistance.

ABSTRACT

ABSTRACT Aim: This study aims to investigate the 90-day and 1-year mortality and the affecting factors of mortality in patients who have started dialysis treatment for the first time. Methods: Patients who started intermittent hemodialysis for the first time in the hemodialysis unit were evaluated. Patients who received hemodialysis treatment for any reason before, patients who underwent hemodialysis due to methyl alcohol, lithium, or mushroom poisoning, and patients who started dialysis in the intensive care unit were excluded from the study. The clinical and laboratory data were obtained from the patients, at admission time, from the electronic data record system and patients' charts.Univariate and multivariate logistic regression analyses were used to identify predictive factors for 90-days and 1-year mortality-dependent variables. Results: 229 patients were included in this study. 133(58.8%) of the patients were male, 96(41.9%) were female, and the median age was 64 years. While 166 patients had pre-existing renal disease, 63 patients had no prior renal disease. The number of patients who died within 90 days, which refers to short-term mortality, was 49 (21.4%). 73 patients (31.9%) died in one year (long-term mortality). At the end of one year, 38% of the whole group of patients continued receiving renal replacement therapy, while 10% of all CKD patients had not a requirement of dialysis, and only 9.17% of the patients had renal recovery. In the multivariate analysis established for short-term mortality, the following parameters showed significant predictive features: ejection fraction (OR = 3.80, 95% CI: 1.05-13.72, p=0.042), CRP (OR = 0.20, 95% CI: 0.04-0.92, p= 0.039), age (OR = 0.21, 95% CI: 0.05-0.91, p= 0.038), and diastolic blood pressure (OR = 0.08, 95% CI: 0.02-0.28, p< 0.001). The multivariate analysis for long-term mortality indicated that systolic blood pressure (OR = 0.26, 95% CI: 0.08-0.82, p= 0.022), diastolic blood pressure (OR = 0.21, 95% CI: 0.68-0.66, p= 0.008), and potassium (OR = 0.27, 95% CI: 0.10-0.70, p= 0.007) were independent predictive markers. Conclusion: Patients with CKD who have not yet started hemodialysis treatment should be followed closely, as hypervolemia, hypotension, and hemodynamic instability increase the risk of death, according to our study. In addition, we recommend that clinical conditions such as hemodynamic instability or sepsis, which may cause hypotension in AKI-D, should be addressed as soon as possible, and optimizing the fluid-electrolyte balance carefully in those patients we determined to be at risk.

RESUMEN Objetivo: Este estudio tiene como objetivo investigar la mortalidad a 90 días y 1 año y los factores que afectan la mortalidad en pacientes que han iniciado tratamiento de diálisis por primera vez. Métodos: Se evaluaron pacientes que iniciaron hemodiálisis intermitente por primera vez en la unidad de hemodiálisis. Se excluyeron del estudio los pacientes que recibieron tratamiento de hemodiálisis por cualquier motivo anteriormente, los pacientes que se sometieron a hemodiálisis por intoxicación con alcohol metílico, litio o hongos y los pacientes que iniciaron diálisis en la unidad de cuidados intensivos. Los datos clínicos y de laboratorio se obtuvieron de los pacientes al momento del ingreso, del sistema de registro electrónico de datos y de las historias clínicas de los pacientes. Se utilizaron análisis de regresión logística univariados y multivariados para identificar factores predictivos para variables dependientes de mortalidad a 90 días y 1 año. Resultados: 229 pacientes fueron incluidos en este estudio. 133 (58,8%) de los pacientes eran hombres, 96 (41,9%) eran mujeres y la mediana de edad fue de 64 años. Mientras que 166 pacientes tenían enfermedad renal preexistente, 63 pacientes no tenían enfermedad renal previa. El número de pacientes que fallecieron dentro de los 90 días, que se refiere a la mortalidad a corto plazo, fue de 49 (21,4%). 73 pacientes (31,9%) fallecieron en un año (mortalidad a largo plazo). Al cabo de un año, el 38% de todo el grupo de pacientes continuaba recibiendo terapia de reemplazo renal, mientras que el 10% de todos los pacientes con ERC no requerían diálisis y solo el 9,17% de los pacientes presentaban recuperación renal. En el análisis multivariante establecido para la mortalidad a corto plazo, los siguientes parámetros mostraron características predictivas significativas: fracción de eyección (OR = 3,80, IC 95%: 1,05-13,72, p=0,042), PCR (OR = 0,20, IC 95%: 0,04 -0,92, p= 0,039), edad (OR = 0,21, IC 95%: 0,05-0,91, p= 0,038) y presión arterial diastólica (OR = 0,08, IC 95%: 0,02-0,28, p< 0,001). El análisis multivariado para la mortalidad a largo plazo indicó que la presión arterial sistólica (OR = 0,26, IC 95%: 0,08-0,82, p= 0,022), la presión arterial diastólica (OR = 0,21, IC 95%: 0,68-0,66, p= 0,008), y el potasio (OR = 0,27, IC 95%: 0,10-0,70, p= 0,007) fueron marcadores predictivos independientes. Conclusión: Los pacientes con ERC que aún no han iniciado tratamiento con hemodiálisis deben ser seguidos de cerca, ya que la hipervolemia, la hipotensión y la inestabilidad hemodinámica aumentan el riesgo de muerte, según nuestro estudio. Además, recomendamos que las condiciones clínicas como la inestabilidad hemodinámica o la sepsis, que pueden causar hipotensión en AKI-D, deben abordarse lo antes posible y optimizar cuidadosamente el balance de líquidos y electrolitos en aquellos pacientes que determinamos que están en riesgo.

ABSTRACT

Health care–associated infections (HAI) directly influence the survival of children in pediatric intensive care units (PICU), the most common being central line–associated bloodstream infection (CLABSI) 25–30%, followed by ventilator-associated pneumonia (VAP) 20–25%, and others such as catheter-associated urinary tract infection (CAUTI) 15%, surgical site infection (SSI) 11%. HAIs complicate the course of the disease, especially the critical one, thereby increasing the mortality, morbidity, length of hospital stay, and cost. The incidence of HAI in Western countries is 6.1–15.1% and in India, it is 10.5 to 19.5%. The advances in healthcare practices have reduced the incidence of HAIs in the recent years which is possible due to strict asepsis, hand hygiene practices, surveillance of infections, antibiotic stewardship, and adherence to bundled care. The burden of drug resistance and emerging infections are increasing with limited antibiotics in hand, is still a dreadful threat. The most common manifestation of HAIs is fever in PICU, hence the appropriate targeted search to identify the cause of fever should be done. Proper isolation practices, judicious handling of devices, regular microbiologic audit, local spectrum of organisms, identification of barriers in compliance of hand hygiene practices, appropriate education and training, all put together in an efficient and sustained system improves patient outcome.

ABSTRACT

@#Pneumonia is a common lower respiratory tract infection, which causes a large disease and economic burden worldwide, and is an important public health problem to be solved urgently. Based on review of publications pertaining to the epidemiology of pneumonia from 2013 to 2023, this article summaries the epidemiological characteristics and main influencing factors of pneumonia. It is found that the epidemiological characteristics of pneumonia vary in different areas; men, the elderly and children are the high-risk groups of pneumonia incidence and mortality; and age, smoking, alcohol consumption, air pollution, comorbidity and vaccination are the main factors affecting the incidence and mortality of pneumonia. Strengthening health education, reducing exposure to risk factors and promoting vaccination are recommended to lower the morbidity and mortality of pneumonia in susceptible populations.

ABSTRACT

Objective:To study the clinical characteristics of different types of neonatal sepsis.Methods:From January 2012 to December 2019, neonates with confirmed sepsis from 5 neonatal centers of central-south China were reviewed. The neonates were assigned into early-onset sepsis (EOS) and late-onset sepsis (LOS) group, and the latter was further subgrouped into hospital-acquired LOS (hLOS) group and community-acquired LOS (cLOS) group. The etiological and clinical characteristics were analyzed. SPSS 26.0 was used for statistical analysis.Results:A total of 580 neonates were enrolled, including 286 (49.3%) in the EOS group and 294 (50.7%) in the LOS group. In LOS group, 147 were in hLOS group and 147 were in cLOS group. The gestational age and birth weight of hLOS group were significantly lower than the other two groups [(32.7±3.6) weeks vs. (37.1±3.7) weeks and (37.7±3.0) weeks, (1 810±717) g vs. (2 837±865) g and (3 024±710) g] ( P<0.05). The common pathogens in EOS and cLOS groups were coagulase-negative staphylococci and Escherichia coli, while Klebsiella pneumoniae was common in hLOS group. Carbapenems usage in the hLOS group was significantly higher than the other two groups [62.6% vs. 28.7% and 16.2%] ( P<0.05). Antibiotics duration in the hLOS group was longer than the other two groups [19 (14, 27) d vs. 15 (12, 20) d and 14 (12, 19) d] ( P<0.05). Conclusions:The clinical characteristics of neonatal sepsis vary among different types of infections, and it is necessary to establish appropriate prevention, control, diagnosis and treatment protocols.

ABSTRACT

Objective:To analyze the factors influencing pulmonary infections in elderly neurocritical patients in the intensive care unit (ICU) and to explore the predictive value of risk factors for pulmonary infections.Methods:The clinical data of 713 elderly neurocritical patients [age ≥ 65 years, Glasgow coma score (GCS) ≤ 12 points] admitted to the department of critical care medicine of the Affiliated Hospital of Guizhou Medical University from 1 January 2016 to 31 December 2019 were retrospectively analyzed. According to whether or not they had HAP, the elderly neurocritical patients were divided into hospital-acquired pneumonia (HAP) group and non-HAP group. The differences in baseline data, medication and treatment, and outcome indicators between the two groups were compared. Logistic regression analysis was used to analyze the factors influencing the occurrence of pulmonary infection.The receiver operator characteristic curve (ROC curve) was plotted for risk factors and a predictive model was constructed to evaluate the predictive value for pulmonary infection.Results:A total of 341 patients were enrolled in the analysis, including 164 non-HAP patients and 177 HAP patients. The incidence of HAP was 51.91%. According to univariate analysis, compared with the non-HAP group, mechanical ventilation time, the length of ICU stay and total hospitalization in the HAP group were significantly longer [mechanical ventilation time (hours): 171.00 (95.00, 273.00) vs. 60.17 (24.50, 120.75), the length of ICU stay (hours): 263.50 (160.00, 409.00) vs. 114.00 (77.05, 187.50), total hospitalization (days): 29.00 (13.50, 39.50) vs. 27.00 (11.00, 29.50), all P < 0.01], the proportion of open airway, diabetes, proton pump inhibitor (PPI), sedative, blood transfusion, glucocorticoids, and GCS ≤ 8 points were significantly increased than those in HAP group [open airway: 95.5% vs. 71.3%, diabetes: 42.9% vs. 21.3%, PPI: 76.3% vs. 63.4%, sedative: 93.8% vs. 78.7%, blood transfusion: 57.1% vs. 29.9%, glucocorticoids: 19.2% vs. 4.3%, GCS ≤ 8 points: 83.6% vs. 57.9%, all P < 0.05], prealbumin (PA) and lymphocyte count (LYM) decreased significantly [PA (g/L): 125.28±47.46 vs. 158.57±54.12, LYM (×10 9/L): 0.79 (0.52, 1.23) vs. 1.05 (0.66, 1.57), both P < 0.01]. Logistic regression analysis showed that open airway, diabetes, blood transfusion, glucocorticoids and GCS ≤ 8 points were independent risk factors for pulmonary infection in elderly neurocritical patients [open airway: odds ratio ( OR) = 6.522, 95% confidence interval (95% CI) was 2.369-17.961; diabetes: OR = 3.917, 95% CI was 2.099-7.309; blood transfusion: OR = 2.730, 95% CI was 1.526-4.883; glucocorticoids: OR = 6.609, 95% CI was 2.273-19.215; GCS ≤ 8 points: OR = 4.191, 95% CI was 2.198-7.991, all P < 0.01], and LYM, PA were the protective factors for pulmonary infection in elderly neurocritical patients (LYM: OR = 0.508, 95% CI was 0.345-0.748; PA: OR = 0.988, 95% CI was 0.982-0.994, both P < 0.01). ROC curve analysis showed that the area under the ROC curve (AUC) for predicting HAP using the above risk factors was 0.812 (95% CI was 0.767-0.857, P < 0.001), with a sensitivity of 72.3% and a specificity of 78.7%. Conclusions:Open airway, diabetes, glucocorticoids, blood transfusion, GCS ≤ 8 points are independent risk factors for pulmonary infection in elderly neurocritical patients. The prediction model constructed by the above mentioned risk factors has certain predictive value for the occurrence of pulmonary infection in elderly neurocritical patients.

ABSTRACT

Healthcare-associated infections (HAI), also referred to as nosocomial infections, is defined as an infection acquired in a hospital setting. This infection is considered a HAI if it was not present or incubating at the time of admission. This includes infections acquired in the hospital but appearing after discharge, and also occupational infections among staff of the facility. HAI are a major patient safety measure to be considered in hospitals.

ABSTRACT

ABSTRACT Objective: To analyze the effect of implementing a bed bath protocol in relation to infection-free time and the prevalence of Healthcare-Associated Infections. Method: A quasi-experimental study with a comparison between two groups. In the Control Group, the data were retrospectively collected between January and April 2018. Implementation of the bed bath protocol in an Intensive Care Unit took place from May to October 2018. Data from the Intervention Group were collected from November 2018 to February 2019 through daily follow-up during the hospitalization period. Results: There were 157 participants in the Control Group and 169 in the Intervention Group, with a mean age of 56 and 54 years old, respectively, and majority of male individuals. The occurrence of Healthcare-Associated Infections was higher in the Control Group (n=32; 20.4%) compared to the Intervention Group (n=10; 5.9%), which presented a 2.86 times lower risk of developing Healthcare-Associated Infections (p<0.01). The Intervention Group presented a longer infection-free time when compared to the Control Group, which had a mean of 2.46 times higher risk of developing infections in the Intensive Care Unit (95%CI: 1.18; 5.11). Conclusion: The study provides support for standardizing the bed bath technique and to preventing health-care associated infections. There is a limitation in generalization of the results, as the groups come from a quasi-experimental before-after design with a non-equivalent Control Group due to the absence of random distribution in the compared groups.

RESUMEN Objetivo: analizar el efecto de implementar un protocolo de higiene de pacientes en la cama en relación con el tiempo sin infección y la prevalencia de Infecciones Relacionadas con la Atención de la Salud. Método: estudio cuasi experimental con comparación entre dos grupos. En el Grupo Control, los datos se recolectaron retrospectivamente entre enero y abril de 2018. La implementación del protocolo de higiene de pacientes en la cama de una Unidad de Cuidados Intensivos tuvo lugar entre mayo y octubre de 2018. Los datos del Grupo Intervención se recolectaron entre noviembre de 2018 y febrero de 2019 por medio del seguimiento diario durante el período de internación. Resultados: hubo 157 participantes en el Grupo Control y 169 en el Grupo Intervención, con una media de edad de 56 y 54 años, respectivamente, y la mayoría del sexo masculino. La incidencia de Infecciones Relacionadas a la Atención de la Salud fue mayor en el Grupo Control (n=32; 20,4%) que en el Grupo Intervención (n=10; 5,9%), y este último presentó 2,86 veces menos riesgo de desarrollar Infecciones Relacionadas a la Atención de la Salud (p<0,01). El Grupo Intervención presentó mayor tiempo sin infección en comparación con el Grupo Control, cuyos participantes tuvieron un promedio de 2,46 veces mayor riesgo de desarrollar infecciones en la Unidad de Cuidados Intensivos (IC95%: 1,18; 5,11). Conclusión: el estudio ofrece aportes para estandarizar la técnica de higiene de pacientes en la cama y prevenir infecciones relacionadas con la atención de la salud. Existe cierta limitación en cuanto a la generalización de los resultados, puesto que los grupos provienen de un diseño cuasiexperimental del tipo "antes-después" con un Grupo Control no equivalente, debido a la ausencia de distribución aleatoria en los grupos comparados.

RESUMO Objetivo: Analisar o efeito da implementação de um protocolo de banho no leito em relação ao tempo livre de infecção e à prevalência de Infecção Relacionada à Assistência à Saúde. Método: Estudo quase experimental, com comparação entre dois grupos. No grupo controle, os dados foram coletados retrospectivamente entre janeiro e abril de 2018. A implementação do protocolo de banho no leito em uma Unidade de Terapia Intensiva ocorreu de maio a outubro de 2018. Os dados do grupo intervenção foram coletados de novembro de 2018 a fevereiro de 2019, por meio do acompanhamento diário durante o período de internação. Resultados: 157 participantes no grupo controle e 169 no grupo intervenção, com média de idade de 56 e 54 anos, respectivamente, sendo a maioria do sexo masculino. A ocorrência de Infecção Relacionada à Assistência à Saúde foi maior no grupo controle (n=32; 20,4%) comparado ao grupo intervenção (n=10; 5,9%), este que apresentou 2,86 menor risco de desenvolver Infecção Relacionada à Assistência à Saúde (p<0,01). O grupo intervenção apresentou maior tempo livre de infecção comparado ao grupo controle, estes que tem, em média, 2,46 vezes maior risco de desenvolver infecção na Unidade de Terapia Intensiva (IC95% 1,18; 5,11). Conclusão: O estudo oferece subsídios para padronização da técnica do banho no leito e prevenção de infecções relacionadas à assistência à saúde. Há limitação na generalização dos resultados, pois os grupos são oriundos de um delineamento quase experimental antes-depois com grupo controle não equivalente, devido à ausência de distribuição aleatória nos grupos comparados.

ABSTRACT

Background: Pneumonia is one of the most important and serious lower respiratory tract infections, which requires implacable attention. This work aimed to document the causative organisms, antibiotics used, and outcome of pneumonia patients hospitalized in a tertiary care hospital. Materials and Methods: A retrospective study was conducted in the medical departments of a tertiary care teaching hospital for 5 years. Demographic details and clinical details including pertinent laboratory values of patients diagnosed with pneumonia were documented and analyzed using a specifically designed data collection form. Results: The study was conducted on 190 patients. The average age of the study population was 56.7 ± 22.6 years and there was a male preponderance of 111(58.4%) patients. Klebsiella pneumonia was found to be the most frequently isolated pathogen in 12.5% of the sputum culture, followed by Acinetobacter baumannii in 10.22% and Pseudomonas aeruginosa in 9.09%. The most commonly prescribed empirical antibiotics were beta-lactam antibiotics mostly in combination with macrolides for synergy irrespective of Pneumonia Severity Index (PSI) classes. Definitive therapy was classified based on World Health Organization (WHO) Access, Watch, and Reserve (AWaRe) classification of antibiotics, watch category antibiotics were prescribed according to culture report and reserve antibiotics were prescribed only in those cases where watch category antibiotics were resistant. On analyzing PSI of community-acquired pneumonia (176 patients), most of the patients in the study belong to class 4: 61 patients (34.7%) and class 5: 44 patients (25%). For the high-risk patients (PSI class 4 and 5), mortality was approximately 3.8% (4 of 105) and for low-risk patients, there was zero mortality reported within 30 days. Conclusion: Gram-negative bacteria were the major pathogens causing Pneumonia in the study site contradictory to the data from developed countries. Identifications of pathogens and appropriate antibiotic therapy based on PSI score can bring down the duration of hospital stay and mortality of patients with pneumonia.

ABSTRACT

Introducción: a partir de la pandemia por Covid19 se reportó variabilidad en la incidencia de las infecciones asociadas al cuidado de la salud (IACS). Con el objetivo de describir y comparar las tasas de IACS en la Unidad de Quemados de un hospital pediátrico de tercer nivel, antes y después del inicio de la pandemia se llevó a cabo este estudio. Material y métodos: estudio de cohorte, retrospectivo, descriptivo, de vigilancia epidemiológica. Se registraron todos los eventos de IACS en la Unidad de Quemados desde el 01/07/2018 hasta el 31/06/2021. Se compararon las tasas de las IACS entre el período I (PI) previo a la pandemia (07/2018-12/2019) y el período II (PII) posterior al inicio de la misma (01/2020- 06/2021). Resultados: se registraron 74 episodios de IACS, en un total de 8232 pacientes-día. Se registró una tasa global de IACS similar en ambos períodos, 10,08 ‰ pacientes-día (PI) vs 7,34 ‰ pacientes-día (PII), sin encontrarse diferencias estadísticamente significativas en las tasas de bacteriemia asociada a catéter venoso central (BSI-CVC) 3,32 ‰ días uso de CVC (PI) vs 3,20 ‰ (PII), neumonía asociada a ARM 1.43 ‰ días de uso de ARM (PI) vs un 2.02 ‰ (PII), ni infección urinaria asociada a sonda vesical (SV) 7,36 ‰ días de uso de SV (PI) vs 3,64 ‰ (PII). Conclusiones: no se observaron diferencias estadísticamente significativas en las tasas de IACS entre ambos períodos, lo cual podría justificarse con el estricto protocolo en control de infecciones implementado previo al inicio de la pandemia (AU)

Introduction: since the start of the Covid19 pandemic, variability in the incidence of healthcare-associated infections (HAIs) has been reported. This study was conducted to describe and compare the rates of HAIs in the burn unit of a tertiary pediatric hospital before and after the onset of the pandemic. Material and methods: a retrospective, descriptive, epidemiological surveillance cohort study was conducted. All HAI events in the burn unit from 01/07/2018 to 31/06/2021 were recorded. HAI rates between the pre-pandemic period I (PI) (07/2018- 12/2019) and post-pandemic period II (PII) (01/2020-06/2021) were compared. Results: 74 episodes of HAI were recorded in a total of 8232 patient-days. There was a similar overall rate of HAIs in both periods, 10.08 ‰ patient-days (PI) vs 7.34 ‰ patient-days (PII), with no statistically significant differences found in the rates of central venous catheter-related bloodstream infections (CVC-BSI) 3.32 ‰ days CVC use (PI) vs 3.20 ‰ (PII), ventilator-associated pneumonia 1. 43 ‰ days MV use (PI) vs a 2.02 ‰ (PII), or catheter-associated urinary tract infection 7.36 ‰ days catheter use (PI) vs 3.64 ‰ (PII). Conclusions: no statistically significant differences were observed in the rates of HAIs between both periods, which may be explained by the strict infection control protocol implemented prior to the onset of the pandemic (AU)

ABSTRACT

ABSTRACT BACKGROUND: Coronavirus disease 19 (COVID-19) is a multisystemic disease with high incidence of acute kidney injury (AKI). OBJECTIVE: To describe the clinical characteristics and factors associated with AKI among patients hospitalized with COVID-19. DESIGN AND SETTING: Retrospective cohort conducted at Hospital Civil de Culiacan, Mexico. METHODS: We included 307 patients hospitalized due to COVID-19. AKI was defined and staged based on serum creatinine levels in accordance with the criteria of the Acute Kidney Injury Network (AKIN). Multivariate logistic regression analysis was used to determine factors associated with AKI. RESULTS: The patients' age was 56 ± 15 years (64.5% male). The incidence of AKI was 33.6% (n = 103). Overall, 53.4% of patients had community-acquired AKI, and 46.6% had hospital-acquired AKI. Additionally, 15.5% of them presented AKIN stage 1; 34% had AKIN stage 2; and 50.5% had AKIN stage 3. Hemodialysis was required for 10.7% of the patients. The factors associated with AKI were chronic kidney disease (odds ratio, OR: 10.8; P = 0.04), use of norepinephrine (OR: 7.3; P = 0.002), diabetes mellitus (OR: 2.9; P = 0.03), C-reactive protein level (OR: 1.005; P = 0.01) and COVID-19 severity index based on chest tomography (OR: 1.09; statistical trend, P = 0.07). Hospital stay (11 ± 7 days; P < 0.001) and mortality (83.5 versus 31.4%; P < 0.05) were greater among patients with AKI. CONCLUSION: AKI was a frequent and serious complication in our cohort of patients hospitalized with COVID-19, which was associated with high mortality and long hospital stay.
