Prospective cohort study of incidence and risk factors for catheter-associated urinary tract infections in 145 intensive care units of 9 Latin American countries: INICC findings.

PURPOSE: Identify urinary catheter (UC)-associated urinary tract infections (CAUTI) incidence and risk factors (RF) in Latin American Countries. METHODS: From 01/01/2014 to 02/10/2022, we conducted a prospective cohort study in 145 ICUs of 67 hospitals in 35 cities in nine Latin American countries: Argentina, Brazil, Colombia, Costa Rica, Dominican Republic, Ecuador, Mexico, Panama, and Peru. To estimate CAUTI incidence, we used the number of UC-days as the denominator, and the number of CAUTIs as numerator. To estimate CAUTI RFs, we analyzed the following 10 variables using multiple logistic regression: gender, age, length of stay (LOS) before CAUTI acquisition, UC-days before CAUTI acquisition, UC-device utilization (DU) ratio, UC-type, hospitalizationtype, ICU type, facility ownership, and time period. RESULTS: 31,631 patients, hospitalized for 214,669 patient-days, acquired 305 CAUTIs. The pooled CAUTI rate per 1000 UC-days was 2.58, for those using suprapubic catheters, it was 2.99, and for those with indwelling catheters, it was 2.21. The following variables were independently associated with CAUTI: age, rising risk 1% yearly (aOR = 1.01; 95% CI 1.01-1.02; p < 0.0001 female gender (aOR = 1.28; 95% CI 1.01-1.61; p = 0.04), LOS before CAUTI acquisition, rising risk 7% daily (aOR = 1.07; 95% CI 1.06-1.08; p < 0.0001, UC/DU ratio (aOR = 1.14; 95% CI 1.08-1.21; p < 0.0001, public facilities (aOR = 2.89; 95% CI 1.75-4.49; p < 0.0001. The periods 2014-2016 and 2017-2019 had significantly higher risks than the period 2020-2022. Suprapubic catheters showed similar risks as indwelling catheters. CONCLUSION: The following CAUTI RFs are unlikely to change: age, gender, hospitalization type, and facility ownership. Based on these findings, it is suggested to focus on reducing LOS, UC/DU ratio, and implementing evidence-based CAUTI prevention recommendations.

Risk factors for bloodstream infection in patients at a Brazilian hemodialysis center: a case-control study.

BACKGROUND: Infection is the leading cause of morbidity and the second leading cause of mortality in patients on renal replacement therapy. The rates of bloodstream infection in hemodialysis patients vary according to the type of venous access used. Gram-positive bacteria are most frequently isolated in blood cultures of hemodialysis patients. This study evaluated risk factors for the development of bloodstream infections in patients undergoing hemodialysis. METHODS: Risk factors associated with bloodstream infections in patients on hemodialysis were investigated using a case-control study conducted between January 2010 and June 2013. Chronic renal disease patients on hemodialysis who presented with positive blood cultures during the study were considered as cases. Controls were hemodialysis patients from the same institution who did not present with positive blood cultures during the study period. Data were collected from medical records. Logistic regression was used for statistical analysis. RESULTS: There were 162 patients included in the study (81 cases and 81 controls). Gram-positive bacteria were isolated with the highest frequency (72%). In initial logistic regression analysis, variables were hypertension, peritoneal dialysis with previous treatment, type and time of current venous access, type of previous venous access, previous use of antimicrobials, and previous hospitalization related to bloodstream infections. Multiple regression analysis showed that the patients who had a central venous catheter had an 11.2-fold (CI 95%: 5.17-24.29) increased chance of developing bloodstream infections compared with patients who had an arteriovenous fistula for vascular access. Previous hospitalization increased the chance of developing bloodstream infections 6.6-fold (CI 95%: 1.9-23.09). CONCLUSIONS: Infection prevention measures for bloodstream infections related to central venous catheter use should be intensified, as well as judicious use of this route for vascular access for hemodialysis. Reducing exposure to the hospital environment through admission could contribute to a reduction in bloodstream infections in this population.

[Prevalence of infection in kidney transplantation from living versus deceased donor: systematic review and meta-analysis]. / Prevalência de infecção em transplante renal de doador vivoversus falecido: revisão sistemática e metanálise.

OBJECTIVE: To verify if the type of donor is a risk factor for infection in kidney transplant recipients. METHODS: Systematic Review of Literature with Meta-analysis with searches conducted in the databases MEDLINE, LILACS, Embase, Cochrane, Web of Science, SciELO and CINAHL. RESULTS: We selected 198 studies and included four observational studies describing infections among patients distinguishing the type of donor. Through meta-analysis, it was shown that in patients undergoing deceased donor transplant, the outcome infection was 2.65 higher, than those who received an organ from a living donor. CONCLUSION: The study showed that deceased kidney donor recipients are at an increased risk for developing infections and so the need for establishing and enforcing protocols from proper management of ischemic time to the prevention and control of infection in this population emerges.

High-touch surfaces disinfection compliance in a COVID-19 intensive care unit.

Environmental cleaning and disinfection are fundamental health care-associated infection prevention measures. This study aimed to evaluate the disinfection compliance of high-touch surfaces in a COVID-19-only intensive care unit, using a fluorescent marker. It was divided into 3 phases, baseline assessment, educational feedback, and post feedback. Disinfection compliance improved significantly from the first to the third phase, 14.3% to 51.4% (P < .001), respectively.

Multinational prospective cohort study of incidence and risk factors for central line-associated bloodstream infections in ICUs of 8 Latin American countries.

BACKGROUND: Our objective was to identify central line (CL)-associated bloodstream infections (CLABSI) rates and risk factors in Latin-America. METHODS: From January 1, 2014 to February 10, 2022, we conducted a multinational multicenter prospective cohort study in 58 ICUs of 34 hospitals in 21 cities in 8 Latin American countries (Argentina, Brazil, Colombia, Costa Rica, Dominican Republic, Ecuador, Mexico, Panama). We applied multiple-logistic regression. Outcomes are shown as adjusted-odds ratios (aOR). RESULTS: About 29,385 patients were hospitalized during 92,956 days, acquired 400 CLABSIs, and pooled CLABSI rate was 4.30 CLABSIs per 1,000 CL-days. We analyzed following 10 variables: Gender, age, length of stay (LOS) before CLABSI acquisition, CL-days before CLABSI acquisition, CL-device utilization (DU) ratio, CL-type, tracheostomy use, hospitalization type, intensive care unit (ICU) type, and facility ownership, Following variables were independently associated with CLABSI: LOS before CLABSI acquisition, rising risk 3% daily (aOR=1.03;95%CI=1.02-1.04; P < .0001); number of CL-days before CLABSI acquisition, rising risk 4% per CL-day (aOR=1.04;95%CI=1.03-1.05; P < .0001); publicly-owned facility (aOR=2.33;95%CI=1.79-3.02; P < .0001). ICU with highest risk was medical-surgical (aOR=2.61;95%CI=1.41-4.81; P < .0001). CL with the highest risk were femoral (aOR=2.71;95%CI=1.61-4.55; P < .0001), and internal-jugular (aOR=2.62;95%CI=1.82-3.79; P < .0001). PICC (aOR=1.25;95%CI=0.63-2.51; P = .52) was not associated with CLABSI risk. CONCLUSIONS: Based on these findings it is suggested to focus on reducing LOS, CL-days, using PICC instead of femoral or internal-jugular; and implementing evidence-based CLABSI prevention recommendations.

Prognosis of patients with heart disease with acute kidney injury undergoing dialysis treatment.

OBJECTIVES: to verify the relationship of cardiovascular diseases with acute kidney injury and assess the prognosis of patients in renal replacement therapy. METHODS: a cohort study, carried out in a public hospital specialized in cardiology. Treatment, comorbidities, duration of treatment, laboratory tests, discharge and deaths were analyzed. RESULTS: of the 101 patients, 75 (74.3%) received non-dialysis treatment. The most frequent cardiological diagnoses were hypertension, cardiomyopathies and coronary syndrome. Hospitalization in patients undergoing dialysis was 18 days, hemoglobin <10.5g/dl and anuria in the first days of hospitalization contributed to the type of treatment. Each increase in hemoglobin units from the first day of hospitalization decreases the chance of dialysis by 19.2%. There was no difference in mortality. CONCLUSIONS: the main cardiological diseases were not predictive of dialysis indication, and clinical treatment was the most frequent. Anuria and anemia were predictors for dialysis treatment.

Multinational Prospective Cohort Study of Mortality Risk Factors in 198 ICUs of 12 Latin American Countries over 24 Years: The Effects of Healthcare-Associated Infections.

BACKGROUND: The International Nosocomial Infection Control Consortium (INICC) has found a high ICU mortality rate in Latin America. METHODS: A prospective cohort study in 198 ICUs of 96 hospitals in 46 cities in 12 Latin American countries to identify mortality risk factors (RF), and data were analyzed using multiple logistic regression. RESULTS: Between 07/01/1998 and 02/12/2022, 71,685 patients, followed during 652,167 patient-days, acquired 4700 HAIs, and 10,890 died. We prospectively collected data of 16 variables. Following 11 independent mortality RFs were identified in multiple logistic regression: ventilator-associated pneumonia (VAP) acquisition (adjusted odds ratio [aOR] = 1.17; 95% CI: 1.06-1.30; p < 0.0001); catheter-associated urinary tract infection (CAUTI) acquisition (aOR = 1.34; 95% CI: 1.15-1.56; p < 0.0001); older age, rising risk 2% yearly (aOR = 1.02; 95% CI: 1.01-1.02; p < 0.0001); longer indwelling central line(CL)-days, rising risk 3% daily (aOR = 1.03; 95% CI: 1.02-1.03; p < 0.0001); longer indwelling urinary catheter(UC)-days, rising risk 1% daily (aOR = 1.01; 95% CI: 1.01-1.26; p < 0.0001); higher mechanical ventilation (MV) (aOR = 6.47; 95% CI: 5.96-7.03; p < 0.0001) and urinary catheter-utilization ratio (aOR = 1.19; 95% CI: 1.11-1.27; p < 0.0001); lower-middle level income country (aOR = 2.94; 95% CI: 2.10-4.12; p < 0.0001); private (aOR = 1.50; 95% CI: 1.27-1.77; p < 0.0001) or public hospital (aOR = 1.47; 95% CI: 1.24-1.74; p < 0.0001) compared with university hospitals; medical hospitalization instead of surgical (aOR = 1.67; 95% CI: 1.59-1.75; p < 0.0001); neurologic ICU (aOR = 4.48; 95% CI: 2.68-7.50; p < 0.0001); adult oncology ICU (aOR = 3.48; 95% CI: 2.14-5.65; p < 0.0001); and others. CONCLUSION: Some of the identified mortality RFs are unlikely to change, such as the income level of the country, facility ownership, hospitalization type, ICU type, and age. But some of the mortality RFs we found can be changed, and efforts should be made to reduce CL-days, UC-days, MV-utilization ratio, UC-utilization ratio, and lower VAPs and CAUTI rates.

Risk factors for colonization and infection by resistant microorganisms in kidney transplant recipients.

OBJECTIVES: to assess the prevalence of colonization and infection by multidrug-resistant bacteria in patients undergoing kidney transplantation and identify the rate of infection, morbidity and mortality and associated risk factors. METHODS: a prospective cohort of 200 randomly included kidney transplant recipients. Epidemiological surveillance of the studied microorganisms was carried out in the first 24 hours and 7 days after transplantation. RESULTS: ninety (45%) patients were considered colonized. Female sex, hypertension and diabetes (p<0.005), dialysis time (p<0.004), length of stay after transplantation, delayed renal function, and length of stay were identified as risk factors. The microorganisms were isolated from surgical site, bloodstream and urinary tract infections. CONCLUSIONS: colonization by resistant microorganisms in kidney transplant patients was frequent and risk factors associated with infection were identified. The results should guide the care team in order to minimize morbidity and mortality related to infectious causes in this population.

Impact of In-Hospital infection with SARS-CoV-2 among Inpatients at a university hospital.

OBJECTIVE: The objective of this study was to evaluate the incidence of nosocomial infection and the impact of cross-transmission of SARS-CoV-2 among inpatients at a tertiary care teaching hospital. METHODS: This was a retrospective cohort study involving inpatients admitted to a tertiary university hospital in the city of São Paulo, Brazil, between March 2020 and February 2021. Cases were identified on the basis of a positive reverse-transcription polymerase chain reaction result for SARS-CoV-2 and the review of electronic medical records. Nosocomial transmission was defined by applying the criteria established by the Brazilian National Health Regulatory Agency. RESULTS: We identified 2146 cases of SARS-CoV-2 infection, 185 (8.6%) of which were considered cases of nosocomial transmission. The mean age was 58.3 years. The incidence density was 1.78 cases per 1,000 patient-days on the general wards, being highest on the cardiac surgery ward, and only 0.16 per 1,000 patient-days on the COVID-19 wards. Of the 185 patients evaluated, 115 (62.2%) were men, 150 (81.1%) cases had at least one comorbidity, and 104 (56.2%) evolved to death. CONCLUSIONS: Despite the preventive measures taken, nosocomial transmission of SARS-CoV-2 occurred throughout our hospital. Such measures should be intensified when the incidence of community transmission peaks.

An eight-year multicenter study on short-term peripheral intravenous catheter-related bloodstream infection rates in 100 intensive care units of 9 countries in Latin America: Argentina, Brazil, Colombia, Costa Rica, Dominican Republic, Ecuador, Mexico, Panama, and Venezuela. Findings of the International Nosocomial Infection Control Consortium (INICC).

BACKGROUND: Data on short-term peripheral intravenous catheter-related bloodstream infections per 1,000 peripheral venous catheter days (PIVCR BSIs per 1,000 PVC days) rates from Latin America are not available, so they have not been thoroughly studied. METHODS: International Nosocomial Infection Control Consortium (INICC) members conducted a prospective, surveillance study on PIVCR BSIs from January 2010 to March 2018 in 100 intensive care units (ICUs) among 41 hospitals, in 26 cities of 9 countries in Latin America (Argentina, Brazil, Colombia, Costa Rica, Dominican-Republic, Ecuador, Mexico, Panama, and Venezuela). The Centers for Disease Control and Prevention (CDC) National Health Safety Network (NHSN) definitions were applied, and INICC methodology and INICC Surveillance Online System software were used. RESULTS: In total, 10,120 ICU patients were followed for 40,078 bed days and 38,262 PVC days. In addition, 79 PIVCR BSIs were identified, with a rate of 2.06 per 1,000 PVC days (95% confidence interval [CI], 1.635-2.257). The average length of stay (ALOS) of patients without a PIVCR BSI was 3.95 days, and the ALOS was 5.29 days for patients with a PIVCR BSI. The crude extra ALOS was 1.34 days (RR, 1.33; 95% CI, 1.0975-1.6351; P = .040).The mortality rate in patients without PIVCR BSI was 3.67%, and this rate was 6.33% in patients with a PIVCR BSI. The crude extra mortality was 1.70 times higher. The microorganism profile showed 48.5% gram-positive bacteria (coagulase-negative Staphylococci 25.7%) and 48.5% gram-negative bacteria: Acinetobacter spp, Escherichia coli, and Klebsiella spp (8.5% each one), Pseudomonas aeruginosa (5.7%), and Candida spp (2.8%). The resistances of Pseudomonas aeruginosa were 0% to amikacin and 50% to meropenem. The resistance of Acinetobacter baumanii to amikacin was 0%, and the resistance of coagulase-negative Staphylococcus to oxacillin was 75%. CONCLUSIONS: Our PIVCR BSI rates were higher than rates from more economically developed countries and were similar to those of countries with limited resources.

Compliance to empirical contact precautions for multidrug-resistant microorganisms.

Health care-associated infections impact patient morbidity and mortality, and institutions adopt evidence-based measures to prevent and control such infections. In this study, professionals were observed during patient care under empirical contact precautions. A total of 243 observations were performed in which 39.5% complied with all measures. The positivity rate of surveillance cultures was 38.36%, and adherence to the measures in patients with colonization was 43.1%.

Strategies for preventing ventilator-associated pneumonia: an integrative review.

OBJECTIVE: to identify studies about strategies for prevention of ventilator-associated pneumonia deployed in health services and classify their level of evidence. METHOD: integrative review of the literature, in 7 databases, which included the following descriptors: Prevention and Control AND Pneumonia Ventilator-Associated AND Intensive Care Units AND Bundle AND Patient Care. RESULTS: twenty-three scientific productions were included. Of the preventive measures identified, 9 (39.1%) correspond from three to five strategies. The most frequent were: 22 (95.6%) lying with head elevated, 19 (82.6%) oral hygiene with chlorhexidine and 14 (60.8%) reduction of sedation whenever possible. FINAL CONSIDERATION: the application of measures based on scientific evidence is proven to be effective when carried out in conjunction, impacting the reduction of the incidence of ventilator-associated pneumonia.

Infection related to Klebsiella pneumoniae producing carbapenemase in renal transplant patients.

OBJECTIVE: To evaluate the risk factors related to Klebsiella pneumoniae carbapenemase infection after renal transplantation. METHODS: This was a retrospective epidemiological (case-control) study, conducted from October 2011 to march 2016. Transplanted patients with infection by this bacteria during hospitalization were selected as cases. The controls were paired by age, sex, type of donor and transplant time. The proportion of cases and controls was 1:2. RESULTS: Thirty hundred and five patients were included in the study (45 cases and 90 controls). The risk factors found for infection by KPC were: time of hospitalization after the transplant (OR: 4.82; CI95% 2.46-9.44), delayed kidney function (OR: 5.60; CI95% 1.91-11.01) and previous infectious for another microorganism ( OR: 34.13 CI95% 3.52-132.00). CONCLUSION: The risk of acquisition of this bacterium was directly related to invasive procedures and exposure to the hospital environment. The findings reinforce the importance of prevention measures and control of infection by this microorganism.

Quality of life of institutionalized aged with and without symptoms of depression.

OBJECTIVE: compare the quality of life (QOL) of aged residents in homes for aged people with or without symptoms of depression, and identify social, physical activity; leisure; health and basic activities of daily living (ADL) variables that correlate with QOL scores. METHOD: cross-sectional study conducted with 101 institutionalized aged. Multiple linear regression was used for data analysis. RESULTS: symptoms of depression changed negatively the QOL in the domains: autonomy; present, past and future activities; social participation; intimacy and total score. Dependent aged presented lower QOL for the performance of ADL in the domains: autonomy; social participation and total score; dancing without limitation of movement; liking the residential and not presenting symptoms of depression were the variables that positively influenced the QOL of the aged. CONCLUSION: social and psychological support, good living conditions and stimulating assistance can improve the QOL of institutionalized elderlies.

Hepatitis B and Delta: clinical aspects of patients in the Brazilian Western Amazonia.

OBJECTIVE: to analyze clinical, serological, biochemical and hematological aspects in patients infected with the hepatitis B (HBV) and Delta (HDV) viruses. METHOD: cross-sectional, descriptive and retrospective study, performed with patients chronically infected with HBV and superinfected with HDV. RESULTS: among the 112 patients selected, 74% were monoinfected with HBV (Group HBV) and 26% were superinfected with HDV (Group HBV+HDV). There was no difference in gender distribution. The average age was 36 years with standard deviation of ±12 years. The symptoms and signs presented a higher proportion in Group HBV+HDV (p=0.001). In both groups, most patients had non-reactive AgHBe. The records of biochemical and hematologic changes showed highest proportion in Group VHB+VHD Group (p<0.05). CONCLUSION: the study found that patients were in clinical stages of the disease different from those in the initial examination for monitoring their chronic condition. The clinical profile suggests greater severity of liver disease among the patients superinfected with HDV.

Alcohol consumption, Quality of Life and Brief Intervention among Nursing university students.

OBJECTIVE: To evaluate nursing university students' alcohol consumption patterns, Brief Intervention and Quality of Life (QoL). METHOD: This is a prospective and longitudinal study containing sociodemographic, economic information concerning alcoholic beverages, BI and QoL evaluation among 281 nursing university students. Since surveys have been applied, seminars have been given and consumption patterns have been discussed, an educational material was delivered after university students' revaluation and BI reinforcement. Descriptive and analytical statistics have been conducted. RESULTS: 90% of the students have already consumed alcohol and 20.6% that consumed for the first time and abused alcohol were minors. After the implementation of BI, the alcohol consumption has decreased among university students. Besides the vitality, generate state of health, and emotional aspects have decreased, mental health was substantially low among the students that used to drink. CONCLUSION: BI contributes to decrease alcoholic beverages consumption and promotes health.

Quality of life in children with kidney transplant: Systematic review.

OBJECTIVE: To identify in the literature studies that evaluate the quality of life in pediatric patients with kidney transplant through use of specific, validated instruments in Pediatrics. METHOD: Systematic review of the literature with searches conducted in the following databases: Medline, PubMed, LILACS, CINAHL, SciELO and Cochrane Library. Main keywords: Quality of life, Kidney transplantation and Pediatrics. RESULTS: A total of 366 studies were selected and eight observational studies were included that evaluated the quality of life of children with kidney transplant by means of evaluation instruments of quality of life. CONCLUSION: The quality of life of children with kidney transplant is inferior compared to healthy children. The post-transplant period presents better results compared to pre-transplant children. The identification of mental, physical and social conditions related to the quality of life of this population allows for better planning the assistance provided to them.

Chronic hepatitis B and D: prognosis according to Child-Pugh score.

OBJECTIVE:: compare chronic hepatitis B patients to those superinfected with hepatitis D virus, according to Child-Pugh score regarding disease severity. METHOD:: retrospective descriptive study, performed with 59 patients followed in the ambulatory, of which 22 (37.3%) were chronically infected with hepatitis B virus (Group HBV) and 37 (62.7%) superinfected with Delta virus (Group HBV+HDV); variables of sex, age and items of Child-Pugh score were collected by consulting medical records. RESULTS:: out of the patients, 57.6% were male, with a mean age of 30.5 years. Score A, which indicates lesser severity, was found in 100% of group HBV and 78.4% of group HBV+HDV. Score B, which indicates greater severity, was found only in group HBV+HDV in 21.6% of the patients. CONCLUSION:: by means of the Child-Pugh score, it was observed that patients with superinfection by HDV tended to present a worse prognosis. OBJETIVO:: comparar os pacientes com hepatite B crônica com superinfectados pelo vírus D segundo escore de Child-Pugh quanto à gravidade da doença. MÉTODO:: estudo descritivo retrospectivo, realizado com 59 pacientes acompanhados em ambulatório, sendo 22 (37,3%) cronicamente infectados pelo vírus da hepatite B (Grupo VHB) e 37 (62,7%) com superinfecção por vírus Delta (Grupo VHB+VHD); foram coletadas variáveis quanto ao sexo, idade e referentes ao escore de Child-Pugh por meio de consulta a prontuários. RESULTADOS:: entre os pacientes 57,6% era do sexo masculino, com idade média de 30,5 anos. O escore A, que indica menor gravidade, foi encontrado em 100% do grupo VHB e 78,4% do grupo VHB+VHD. O escore B, que indica maior gravidade, foi encontrado apenas no grupo VHB+VHD em 21,6% dos pacientes. CONCLUSÃO:: por meio do escore de Child-Pugh, observou-se que os pacientes com superinfecção por VHD tendem a apresentar pior prognóstico.
