An observational case study of hospital associated infections in a critical care unit in Astana, Kazakhstan

BackgroundHospital Associated infections (HAI) are very common in Intensive Care Units (ICU) and are usually associated with use of invasive devices in the patients. This study was conducted to determine the prevalence and etiological agents of HAI in a Surgical ICU in Kazakhstan, and to assess the impact of these infections on ICU stay and mortality.ObjectiveTo assess the rate of device-associated infections and causative HAI etiological agents in an ICU at the National Research Center for Oncology and Transplantation (NRCOT) in Astana, Kazakhstan.MethodsThis retrospective, observational study was conducted in a 12-bed ICU at the NRCOT, Astana, Kazakhstan. We enrolled all patients who were admitted to the ICU from January, 2014 through November 2015, aged 18 to 90 years of age who developed an HAI.ResultsThe most common type of HAI was surgical site infection (SSI), followed by ventilator-associated pneumonia (VAP), catheter-related blood stream infection (BSI) and catheter-associated urinary tract infection (UTI). The most common HAI was SSI with Pseudomonas aeruginosa as the most common etiological agent. The second most common HAI was VAP also with P. aeruginosa followed by BSI which was also associated with P. aeruginosa (in 2014) and Enterococcus faecalis, and Klebsiella pneumoniae (in 2015) as the most common etiological agents causing these infections.ConclusionWe found that HAI among our study population were predominantly caused by gram-negative pathogens, including P. aeruginosa, K. pneumoniae, and E. coli. To our knowledge, this is the only study that describes ICU-related HAI situation from a country within the Central Asian region. Many developing countries such as Kazakhstan lack surveillance systems which could effectively decrease incidence of HAIs and healthcare costs for their treatment. The epidemiological data on HAI in Kazakhstan currently is underrepresented and poorly reported in the literature. Based on this and previous studies, we propose that the most important interventions to prevent HAI at the NRCOT and similar Healthcare Institutions in Kazakhstan are active surveillance, regular infection control audits, rational and effective antibacterial therapy, and general hygiene measures.

Trends in device utilization ratios in intensive care units over 10-year period in South Korea: device utilization ratio as a new aspect of surveillance

Device-associated infection (DAI) is an important issue related to patient safety. It is important to reduce unnecessary device utilization in order to decrease DAI rates. To investigate the time trend of device utilization ratios (DURs) of voluntarily participating hospitals, collected over a 10-year period through the Korean National Healthcare-associated Infections Surveillance System (KONIS). DURs from 2006 to 2015 in 190 intensive care units (ICUs) participating in KONIS were included in this study. DURs were calculated as the ratio of device-days to patient-days. The pooled incidences of DAIs and DURs were calculated for each year of participation, and the year-wise trends were analysed. Year-wise ventilator utilization ratio (V-DUR) increased significantly from 0.40 to 0.41 (F=6.27, P<0.01), urinary catheter utilization ratio (U-DUR) increased non-significantly from 0.83 to 0.84 (F=1.66, P=0.10), and C-line utilization ratio (CL-DUR) decreased non-significantly from 0.55 to 0.51 (F=1.62, P=0.11). In the subgroup analysis, 'medical ICU' (F=2.79, P<0.01) and 'hospital with >900 beds' (F=3.07, P<0.01) were associated with the significant increase in V-DUR. In Korea, V-DUR showed a significant, year-wise increasing trend. The trends for U-DUR and CL-DUR showed no significant decrease. Efforts are required to ensure the reduction of DURs.

Care bundle approach to reduce device-associated infections in a tertiary care teaching hospital, South India.

CONTEXT:The care bundle approach is a set of evidence-based practices that when performed collectively and reliably have been shown to improve the patient outcome.AIMS:To evaluate the impact of the bundle care approach on reducing device-associated infections (DAIs).SETTINGS AND DESIGN:The study was conducted at a tertiary care hospital, South India. The study period was from January 2016 to September 2016 which was divided into three phases, each comprising 3 months.SUBJECTS AND METHODS:During the implementation phase, bundle care forms were implemented in all Intensive Care Units (ICUs) and the ICU staff were given a basic education on the importance of bundle care approach. The DAI rates (ventilator-associated pneumonia [VAP] rates, central line-associated bloodstream infection [CLABSI] rate, and catheter-associated urinary tract infection [CAUTI] rate) were calculated throughout the study period.STATISTICAL ANALYSIS USED:Statistical analysis was performed using SPSS 19 software.RESULTS:During preimplementation phase, the VAP rate, CLABSI rate, and CAUTI rate were 14.79, 4.98, and 4.86 per 1000 device days, respectively. Rates were reduced to 13.03, 3.98, and 3.39 per 1000 device days, respectively, during the implementation phase and further reduced into 11.91, 3.49, and 2.36 per 1000 device days during the postimplementation phase. The month-wise decreasing trend of DAI rates was significant for medical ICUs as compared to surgical and pediatric ICUs.CONCLUSIONS:The month-wise decreasing trend of VAP rate, CLABSI rate, and CAUTI rate was noted, which signifies that the use of care bundle approach has a great impact on reducing DAIs

Impact of a hand hygiene audit on hand hygiene compliance in a tertiary care public sector teaching hospital in South India.

Hand hygiene (HH) practice is considered the most simple, cost-effective, and efficient way to prevent device-associated infections. Continuous auditing plays a vital role in the conversion of HH knowledge into practice. An HH audit was carried out October 2015-September 2016 in 18 locations for a total of 1,080 observation periods and 64,800 minutes of observation. HH complete adherence rate (HHCAR) and HH partial adherence rate were analyzed. The HHCAR, HH partial adherence rate, and nonadherence rate were 45.5%, 21.17%, and 33.3%, respectively. There was gradual statistically significant increase in monthly HHCAR during the study period from 37.5%-51.7% (P = .001). HHCAR was found to be highest among nurses (58.9%) followed by other staff (46.7%) and doctors (46.6%). World Health Organization Moments 3 and 4 had statistically significant compliance (78.5% and 71.8%, respectively; P < .001) compared with Moments 1, 2, and 5. As the HHCAR increases there is statistically significant decrease in device-associated infection rate from 10.6-3.9 per 1,000 device days (P = .042). HH audit has a significant influence on HH compliance. More emphasis needs to be given on compliance with HH practice by doctors and with the World Health Organization "before" Moments, especially. HH audits should be a part of the infection control manual of every hospital.

Device-associated infection rates, mortality, length of stay and bacterial resistance in intensive care units in Ecuador: International Nosocomial Infection Control Consortium's findings.

AIMTo report the results of the International Nosocomial Infection Control Consortium (INICC) study conducted in Quito, Ecuador.METHODSA device-associated healthcare-acquired infection (DA-HAI) prospective surveillance study conducted from October 2013 to January 2015 in 2 adult intensive care units (ICUs) from 2 hospitals using the United States Centers for Disease Control/National Healthcare Safety Network (CDC/NHSN) definitions and INICC methods.RESULTSWe followed 776 ICU patients for 4818 bed-days. The central line-associated bloodstream infection (CLABSI) rate was 6.5 per 1000 central line (CL)-days, the ventilator-associated pneumonia (VAP) rate was 44.3 per 1000 mechanical ventilator (MV)-days, and the catheter-associated urinary tract infection (CAUTI) rate was 5.7 per 1000 urinary catheter (UC)-days. CLABSI and CAUTI rates in our ICUs were similar to INICC rates [4.9 (CLABSI) and 5.3 (CAUTI)] and higher than NHSN rates [0.8 (CLABSI) and 1.3 (CAUTI)] - although device use ratios for CL and UC were higher than INICC and CDC/NSHN’s ratios. By contrast, despite the VAP rate was higher than INICC (16.5) and NHSN’s rates (1.1), MV DUR was lower in our ICUs. Resistance of A. baumannii to imipenem and meropenem was 75.0%, and of Pseudomonas aeruginosa to ciprofloxacin and piperacillin-tazobactam was higher than 72.7%, all them higher than CDC/NHSN rates. Excess length of stay was 7.4 d for patients with CLABSI, 4.8 for patients with VAP and 9.2 for patients CAUTI. Excess crude mortality in ICUs was 30.9% for CLABSI, 14.5% for VAP and 17.6% for CAUTI.CONCLUSIONDA-HAI rates in our ICUs from Ecuador are higher than United States CDC/NSHN rates and similar to INICC international rates.

Multicenter prospective study on device-associated infection rates and bacterial resistance in intensive care units of Venezuela: International Nosocomial Infection Control Consortium (INICC) findings.

Device-associated healthcare-acquired infections (DA-HAI) pose a threat to patient safety in the intensive care unit (ICU). A DA-HAI surveillance study was conducted by the International Nosocomial Infection Control Consortium (INICC) in two adult medical/surgical ICUs at two hospitals in Caracas, Venezuela, in different periods from March 2008 to April 2015, using the US Centers for Disease Control and Prevention's National Healthcare Safety Network (CDC/NHSN) definitions and criteria, and INICC methods. We followed 1041 ICU patients for 4632 bed days. Central line-associated bloodstream infection (CLABSI) rate was 5.1 per 1000 central line days, ventilator-associated pneumonia (VAP) rate was 7.2 per 1000 mechanical ventilator days, and catheter-associated urinary tract infection (CAUTI) rate was 3.9 per 1000 urinary catheter days, all similar to or lower than INICC rates (4.9 [CLABSI]; 16.5 [VAP]; 5.3 [CAUTI]), and higher than CDC/NHSN rates (0.8 [CLABSI]; 1.1 [VAP]; and 1.3 [CAUTI]). Device utilization ratios were higher than INICC and CDC/NHSN rates, except for urinary catheter, which was similar to INICC. Extra length of stay was 8 days for patients with CLABSI, 9.6 for VAP and 5.7 days for CAUTI. Additional crude mortality was 3.0% for CLABSI, 4.4% for VAP, and 16.9% for CAUTI. DA-HAI rates in our ICUs are higher than CDC/NSHN's and similar to or lower than INICC international rates.

Implementation of active surveillance system to track hospital-acquired infections in a tertiary care hospital in India

Background: Hospital-acquired infections (HAIs) are a threat to public health and addressing this issue will help to plan appropriate preventive strategies. Full-fledged active HAIs surveillance is the cornerstone in assessing the burden of HAIs. This study was planned to assess the burden of HAIs by implementing a hospital-wide active surveillance system in a large tertiary care teaching hospital in south India and compare findings with those of National Health Safety Network United States (NHSN US) and International Nosocomial Infection Control Consortium (INICC) India HAI rates. Materials and Methods: Active HAIs' surveillance was initiated in 18 Intensive Care Units (ICUs) from January 2015 to September 2016. All patients admitted in the ICUs were followed up by the infection control nurses, and surveillance was done for device-associated infections (DAIs). The cumulative rates of the DAIs and device utilization (DU) rates and surgical site infection (SSI) rates were determined for all the ICUs. These data were compared with corresponding NHSN and INICC India HAI rates. Results: Total number of patient days for the entire study period was 111294, pooled mean ventilator-associated pneumonia rate was 25.00/1000 ventilator days (NHSN US 2.0 and INICC India 9.4); Pooled mean central line-associated blood stream infection rate was 7.2/1000 central line days (NHSN US 1.1 and INICC India 5.1). The pooled mean ICU catheter-associated urinary tract infection rate was 6.1/1000 catheter days (2.1 NHSN US and 2.9 INICC India). The pooled mean SSI rate was found to be 3.5/100 surgeries. The DU rates had a significant positive agreement with the DAI rates. The DAI rates of most of the ICUs were found be to be higher than NHSN US and INICC India rates. Conclusion: There is an increasing need to implement an active surveillance system to detect and monitor the HAI rates which would be vital to implement infection control measures in a proactive manner rather than reactive.

Device-associated nosocomial infection in general hospitals, Kingdom of Saudi Arabia, 2013–2016

Healthcare-associated infections (HAIs) including device-associated HAI (DA-HAI) are a serious patient safety issue in hospitals worldwide, affecting 5–10% of hospitalized patients and deadly for patients in intensive care units (ICUs). (Vincent, 2003; Al-Tawfiq et al., 2013; Hu et al., 2013). DA-HAIs account for up to 23% of HAIs in ICUs and about 40% of all hospital infections (i.e. central line-associated blood stream infections [CLABSI], ventilator-associated pneumonia [VAP], and catheter-associated urinary tract infections [CAUTI]). This study aims to identify DA-HAI rates among a group of selected hospitals in the Kingdom of Saudi Arabia (KSA), 2013–2016. Secondary data was analyzed from 12 medical/surgical intensive care units (M/SICUs) and two cardiac care units (CCUs) from 12 Ministry of Health (MoH) hospitals from different regions in KSA. These data were reported by infection control practitioners to the MoH via electronic International Nosocomial Infection Control Consortium (INICC) systems in each hospital. Among 6178 ICU patients with 13,492 DA-HAIs during 2013–2016, the average length of stay (LOS) was 10.7 days (range 0–379 days). VAP was the most common DA-HAI (57.4%), followed by CAUTI (28.4%), and CLABSI (14.2%). In CCUs there were no CLABSI cases; CAUTI was reported from 1 to 2.6 per 1000 device-days; and VAP did not occur in Hospital B but occurred 8.1 times per 1000 device-days in the CCU in Hospital A. In M/SICUs, variations occurred among time periods, hospitals, and KSA provinces. CLABSI varied between hospitals from 2.2 to 10.5 per 1000 device-days. CAUTI occurred from 2.3 to 4.4 per 1000 device-days, while VAP had the highest rates, from 8.9 to 39.6 per 1000 device-days. Most hospitals had high device-utilization ratios (DURs) (from the 75th to 90th percentile of National Healthcare Safety Network (NHSN)’s standard and the 50th to 75th percentile of INICC’s). This study showed higher device-associated infection rates and higher device-utilization ratios in the study’s CCUs and M/SICUs than NHSN benchmarks. To reduce the rates of infection, ongoing monitoring of infection control practices and comprehensive education are required. Furthermore, a sensitive and specific national healthcare safety network is needed in KSA.

Device-associated infection rates with microbiological profile and antibiogram pattern from an adult medical-surgical intensive care unit of a tertiary care hospital

Abstract Introduction Ubiquitous medical devices are major cause of health care associated infections. Surveillance of these infections plays a key role in control of hospital-acquired infections. Materials and methods In a prospective surveillance in medical surgical intensive care unit, device-associated health care associated infection rates were calculated using the National Nosocomial Infection Surveillance System and National Healthcare Safety Network guidelines. Results Fifty-four episodes of device-associated infections were documented among 563 patients. Rates for ventilator-associated pneumonia, central line-associated bloodstream infections and catheter-associated urinary tract infections were 16.7, 10.3 and 7.3 respectively with the overall device-associated nosocomial infection rate of 24.6/1000 days. The device utilization ratio was maximum for urinary catheter (0.99:1) followed by 0.68:1 for ventilator and 0.57:1 for central line. An overall crude excess mortality of 30.3% was observed. 40.7% of device-associated health care associated infections were caused by Klebsiella species. Imipenem and vancomycin showed maximum sensitivity to gram negative and positive organisms respectively. Conclusion Device-associated health care associated infections, the principal threat to patient safety in the intensive care unit, are among the predominant causes of patient morbidity and mortality. Surveillance of these infections allows estimation of infection control measures adopted.

Device-associated infections in a paediatric intensive care unit in Pakistan

This study assessed the effect of implementation of active infection control and surveillance on the occurrence of device-associated infections (DAIs) in a paediatric intensive care unit (PICU) from 2012 to 2015. There were 1378 patients, equating to 4632 patient-days, on the PICU, and 29 DAI episodes, giving an incidence rate of 2.1% and an incidence density rate of 6.26 per 1000 patient-days. The rates of central-line-associated bloodstream infections, ventilator-associated pneumonia and catheter-related urinary tract infections were 7/1000 central-line-days, 1.17/1000 ventilator-days and 0.24/1000 urinary-catheter-days, respectively. Despite the overall low rate of DAIs in the PICU, there was a relatively high rate of central-line-associated bloodstream infections.

The Incidence of Device Associated Infections, Causative Microorganisms And Antibiotic Sensitivity Pattern in Icu

Hospital acquired infections are infections that are neither present nor incubating when a patient enters hospital 1 . Despite progress in public health and hospital care, infections continue to develop in hospitalized patients, and may also affect hospital staff. 2 About nine per cent of inpatients have a hospital acquired infection at point of time. (3) Their effects vary from discomfort, functional disability and emotional stress to prolonged or permanent disability . Small proportion of patient deaths each year are primarily attributable to hospital acquired infections (2,3) . The economic costs are considerable. The increased length of stay for infected patients is the greatest contributor to cost. 2 The development of a surveillance process to monitor this rate is an essential first step to identify local problems and priorities, and evaluate the effectiveness of infection control activity. Surveillance, by itself, is an effective process to decrease the frequency of hospital-acquired infections. 2,5 This study was undertaken as a part of surveillance system for MICU to find out incidence of device associated infection rate, causative microorganisms and their antibiotic sensitivity pattern. In this study the attack rate of catheter associated Urinary Tract Infection was 52.63% and incidence of 83.33% per 1000 catheter days. Most common organisms isolated were Klebsiella (63.63%,) E-Coli (31.81% ) and Pseudomonas (4.54%). Eighty one percent of Klebsiella isolates, 76.47% of E. Coli isolates and 87.5% of Pseudomonas isolates were resistant for antibiotics tested. Out of total isolates tested, 58.82% were resistant to Gentamycin, 100% isolates were resistant to Ampicillin and Cefotaxim, 80% were resistant to Ciprofloxacin, 87.5% were resistant to Sulphamethaxazole and 42.10% were resistant to Furantoin. The proportion of days spent in the ICU in which the patient's treatment included invasive devices is increasing, in fact 25-50% of nosocomial infections are due to combined effect of the patient's own flora and invasive devices . Catheter-associated urinary tract infection (UTI), Central line-associated bloodstream infection (BSI), Ventilator-associated pneumonia (VAP) are among leading causes of mortality and morbidity among ICU patients.

Active surveillance of hospital-acquired infections in South Africa: Implementation, impact and challenges.

Hospital-acquired infections (HAIs) are a significant although unquantified burden in South Africa. Lack of adequate surveillance compounds this problem. To report on the establishment and outcomes of a unit-specific surveillance system for hospital-acquired infections, based on international standards, in a private academic hospital. Active unit-specific surveillance of device-associated infections (DAIs) was introduced over a 2-year period. The surveillance system was based on the US National Healthcare Safety Network (NHSN) utilising standardised definitions. Analysis of DAI rates and device utilisation was done according to Centers for Disease Control and Prevention methods. Comparative analysis using study-derived annualised data and existing NHSN data was done. Surveillance results of DAI rates showed significant reductions in intensive care unit-related ventilator-associated pneumonia (42%) and central line-associated bloodstream infections (100%) over a 3-year period. Substantial variations in DAI rates and utilisation ratios between wards highlight the importance of unit-specific surveillance. Active surveillance requires a significant investment in resources and is a sustained operational challenge, although equally significant benefits are derived from a better understanding of HAIs with more targeted interventions and efficient use of resources. A robust surveillance system is an essential component of any healthcare infection prevention and control programme and is a prerequisite to contextualising the HAI burden of hospitals.

Device-associated infection rates, bacterial resistance, length of stay, and mortality in Kuwait: International Nosocomial Infection Consortium findings

To report the results of the International Infection Control Consortium (INICC) study conducted in Kuwait from November 2013-March 2015. A device-associated health care-acquired infection (DA-HAI) prospective surveillance study in 7 adult, pediatric, and neonatal intensive care units (ICUs) using the U.S. Centers for Disease Control and Prevention's (CDC's) National Healthcare Safety Network (NHSN) definitions and INICC methods. We followed 3,732 adult and pediatric patients for 21,611 bed days and 671 neonatal patients for 4,515 bed days. In the medical-surgical ICUs, the central line-associated bloodstream infection (CLABSI) rate was 3.5 per 1,000 central line days, the ventilator-associated pneumonia (VAP) rate was 4.0 per 1,000 mechanical ventilator days, and the catheter-associated urinary tract infection (CAUTI) rate was 3.3 per 1,000 urinary catheter days; all of them were lower than INICC rates (CLABSI: 4.9; VAP: 16.5; and CAUTI: 5.3) and higher than NHSN rates (CLABSI: 0.9; VAP: 1.1; and CAUTI: 1.2). Resistance of Staphylococcus aureus to oxacillin was 100%, resistance of Acinetobacter baumannii to imipenem and meropenem was 77.6%, and resistance of Klebsiella pneumoniae to imipenem and meropenem was 29.4%. Extra length of stay was 27.1 days for CLABSI, 22.2 days for VAP, and 19.2 days for CAUTI in adult and pediatric ICUs. Extra crude mortality was 19.9% for CLABSI, 30.9% for VAP, and 11.1% for CAUTI in adult and pediatric ICUs. DA-HAI rates in our ICUs are higher than the CDC-NSHN rates and lower than the INICC international rates.

Medical Device-Associated Candida Infections in a Rural Tertiary Care Teaching Hospital of India.

Health care associated infections (HCAIs) add incrementally to the morbidity, mortality, and cost expected of the patient's underlying diseases alone. Approximately, about half all cases of HCAIs are associated with medical devices. As Candida medical device-associated infection is highly drug resistant and can lead to serious life-threatening complications, there is a need of continuous surveillance of these infections to initiate preventive and corrective measures. The present study was conducted at a rural tertiary care hospital of India with an aim to evaluate the rate of medical device-associated Candida infections. Three commonly encountered medical device-associated infections (MDAI), catheter-associated urinary tract infection (CA-UTI), intravascular catheter-related blood stream infections (CR-BSI), and ventilator-associated pneumonia (VAP), were targeted. The overall rate of MDAI in our hospital was 2.1 per 1000 device days. The rate of Candida related CA-UTI and CR-BSI was noted as 1.0 and 0.3, respectively. Untiring efforts taken by team members of Hospital Acquired Infection Control Committee along with maintenance of meticulous hygiene of the hospital and wards may explain the low MDAI rates in our institute. The present surveillance helped us for systematic generation of institutional data regarding MDAI with special reference to role of Candida spp.

Multicenter study of device-associated infection rates in hospitals of Mongolia: Findings of the International Nosocomial Infection Control Consortium (INICC)

A device-associated health care-associated infection prospective surveillance study in 3 adult intensive care units (ICUs) from 3 hospitals using the U.S. Centers for Disease Control and Prevention (CDC) and National Healthcare Safety Network (NHSN) definitions and INICC methods. We documented 467 ICU patients for 2,133 bed days. The central line-associated bloodstream infection (CLABSI) rate was 19.7 per 1,000 central line days, the ventilator-associated pneumonia (VAP) rate was 43.7 per 1,000 mechanical ventilator days, and the catheter-associated urinary tract infection (CAUTI) rate was 15.7 per 1,000 urinary catheter days; all of the rates are higher than the INICC rates (CLABSI: 4.9; VAP: 16.5; and CAUTI: 5.3) and CDC-NHSN rates (CLABSI: 0.8; VAP: 1.1; and CAUTI: 1.3). Device use ratios were also higher than the CDC-NHSN and INICC ratios, except for the mechanical ventilator device use ratio, which was lower than the INICC ratio. Resistance of Staphylococcus aureus to oxacillin was 100%. Extra length of stay was 15.1 days for patients with CLABSI, 7.8 days for patients with VAP, and 8.2 days for patients with CAUTI. Extra crude mortality in the ICUs was 18.6% for CLABSI, 17.1% for VAP, and 5.1% for CAUTI. Device-associated health care-associated infection rates and most device use ratios in our Mongolian hospitals' ICUs are higher than the CDC-NSHN and INICC rates.

Device-Associated Infection Rates in 20 Cities of India, Data Summary for 2004-2013: Findings of the International Nosocomial Infection Control Consortium.

To report the International Nosocomial Infection Control Consortium surveillance data from 40 hospitals (20 cities) in India 2004-2013. Surveillance using US National Healthcare Safety Network's criteria and definitions, and International Nosocomial Infection Control Consortium methodology. We collected data from 236,700 ICU patients for 970,713 bed-days Pooled device-associated healthcare-associated infection rates for adult and pediatric ICUs were 5.1 central line-associated bloodstream infections (CLABSIs)/1,000 central line-days, 9.4 cases of ventilator-associated pneumonia (VAPs)/1,000 mechanical ventilator-days, and 2.1 catheter-associated urinary tract infections/1,000 urinary catheter-days In neonatal ICUs (NICUs) pooled rates were 36.2 CLABSIs/1,000 central line-days and 1.9 VAPs/1,000 mechanical ventilator-days Extra length of stay in adult and pediatric ICUs was 9.5 for CLABSI, 9.1 for VAP, and 10.0 for catheter-associated urinary tract infections. Extra length of stay in NICUs was 14.7 for CLABSI and 38.7 for VAP Crude extra mortality was 16.3% for CLABSI, 22.7% for VAP, and 6.6% for catheter-associated urinary tract infections in adult and pediatric ICUs, and 1.2% for CLABSI and 8.3% for VAP in NICUs Pooled device use ratios were 0.21 for mechanical ventilator, 0.39 for central line, and 0.53 for urinary catheter in adult and pediatric ICUs; and 0.07 for mechanical ventilator and 0.06 for central line in NICUs. Despite a lower device use ratio in our ICUs, our device-associated healthcare-associated infection rates are higher than National Healthcare Safety Network, but lower than International Nosocomial Infection Control Consortium Report.

Trends in the incidence rate of device-associated infections in intensive care units after the establishment of the Korean Nosocomial Infections Surveillance System

The effectiveness of continuous nationwide surveillance on healthcare-associated infections should be investigated in each country. To assess the rate of device-associated infections (DAIs) in intensive care units (ICUs) since the establishment of the Korean Nosocomial Infections Surveillance System (KONIS). Nationwide data were obtained on the incidence rate of DAI in ICUs reported to KONIS by all participating hospitals. The three major DAIs were studied: ventilator-associated pneumonia (VAP), central line-associated bloodstream infection (CABSI), and catheter-associated urinary tract infection (CAUTI). The pooled and year-wise incidence rates (cases per 1000 device-days) of these DAIs were determined for the period 2006 and 2012. In addition, data from institutions that had participated in KONIS for at least three consecutive years were analysed separately. The number of ICUs participating in KONIS gradually increased from 76 in 2006 to 162 in 2012. Between 2006 and 2012, the incidence rate per 1000 device-days for VAP decreased significantly from 3.48 to 1.64 (F = 11, P < 0.01), for CAUTI the rate decreased non-significantly from 1.85 to 1.26 (F = 2.02, P = 0.07), and for CABSI the rate also decreased non-significantly from 3.4 to 2.57 (F = 1.73, P = 0.12). In the 132 ICUs that had participated in KONIS for at least three consecutive years, the VAP rate significantly decreased from the first year to third year (F = 20.57, P < 0.01), but the rates of CAUTI (F = 1.06, P = 0.35) and CABSI (F = 1.39, P = 0.25) did not change significantly. The decreased incidence rate of VAP in ICUs in Korea might be associated with the continuous prospective surveillance provided by KONIS.

Device-associated infection rates and bacterial resistance in six academic teaching hospitals of Iran: Findings from the International Nocosomial Infection Control Consortium (INICC).

Device-associated health care-acquired infections (DA-HAIs) pose a threat to patient safety, particularly in the intensive care unit (ICU). However, few data regarding DA-HAI rates and their associated bacterial resistance in ICUs from Iran are available. A DA-HAI surveillance study was conducted in six adult and pediatric ICUs in academic teaching hospitals in Tehran using CDC/NHSN definitions. We collected prospective data regarding device use, DA-HAI rates, and lengths of stay from 2584 patients, 16,796 bed-days from one adult ICU, and bacterial profiles and bacterial resistance from six ICUs. Among the DA-HAIs, there were 5.84 central line-associated bloodstream infections (CLABs) per 1000 central line-days, 7.88 ventilator-associated pneumonias (VAPs) per 1000 mechanical ventilator-days and 8.99 catheter-associated urinary tract infections (CAUTIs) per 1000 urinary catheter-days. The device utilization ratios were 0.44 for central lines, 0.42 for mechanical ventilators and 1.0 for urinary catheters. The device utilization ratios of mechanical ventilators and urinary catheters were higher than those reported in the ICUs of the INICC and the CDC's NHSN reports, but central line use was lower. The DA-HAI rates in this study were higher than the CDC's NHSN report. However, compared with the INICC report, the VAP rate in our study was lower, while the CLAB rate was similar and the CAUTI rate was higher. Nearly 83% of the samples showed a mixed-type infection. The most frequent pathogens were Acinetobacter baumannii, Staphylococcus aureus and Pseudomonas aeruginosa, followed by Klebsiella pneumoniae and Enterococcus spp. In the S. aureus isolates, 100% were resistant to oxacillin. Overall resistances of A. baumannii and K. pneumonia to imipenem were 70.5% and 76.7%, respectively. A multiple drug resistance phenotype was detected in 68.15% of the isolates. The DA-HAI rates in Iran were shown to be higher than the CDC-NHSN rates and similar to the INICC rates. Resistance to oxacillin and imipenem was higher as well. Comparing device use, DA-HAI rates, and bacterial resistance for the primary isolated bacteria indicated a direct association between urinary catheter use and the rates of CAUTI.
