Proportion Of Healthcare-associated Infections Research Articles

Incidence of healthcare-associated infections among puerperas and newborns in Russian Federation

One of the leading problems of modern public health is healthcare-associated infections (HAIs), which lead to significant social and economic damage, and affect the quality of medical care. The proportion of HAIs in obstetric institutions among all the Ministry of Defense of the Russian Federation for 9 years decreased by 1.7 times. The number of puerperas of HAIs decreased by 1.4 times, and HAIs of newborns decreased by 1.6 times. The proportion of puerperal sepsis in the structure of purulent-septic infections of puerperas is 1.7 ± 0.5 %, and sepsis of newborns is 4.4 ± 1.5 %. The average incidence of puerperas of IUPS was 2.0 ± 2.1 per 1,000 births. The incidence of HAIs in newborns was 2.0 ± 1.8 per 1,000 newborns. The ratio of HAIs of newborns to intrauterine infections on average was 1: 9, and in some regions 1:2–1:150. The obtained data on the incidence of HAIs in puerperas and newborns indicates the insufficiency of a systematic approach to recording, analyzing and predicting the incidence of HAIs, which requires a detailed development of standard epidemiological definitions of the case HAIs of puerperas and newborns, intrauterine infections of newborns, as well as a detailed analysis of risk factors for the development of HAIs in obstetric facilities.

Incidence of healthcare-associated infections in a tertiary hospital in Beijing, China: results from a real-time surveillance system

BackgroundTo quantify the five year incidence trend of all healthcare-associated infections (HAI) using a real-time HAI electronic surveillance system in a tertiary hospital in Beijing, China.MethodsThe real-time surveillance system scans the hospital’s electronic databases related to HAI (e.g. microbiological reports and antibiotics administration) to identify HAI cases. We conducted retrospective secondary analyses of the data exported from the surveillance system for inpatients with all types of HAIs from January 1st 2013 to December 31st 2017. Incidence of HAI is defined as the number of HAIs per 1000 patient-days. We modeled the incidence data using negative binomial regression.ResultsIn total, 23361 HAI cases were identified from 633990 patients, spanning 6242375 patient-days during the 5-year period. Overall, the adjusted five-year HAI incidence rate had a marginal reduction from 2013 (4.10 per 1000 patient days) to 2017 (3.62 per 1000 patient days). The incidence of respiratory tract infection decreased significantly. However, the incidence rate of bloodstream infections and surgical site infection increased significantly. Respiratory tract infection (43.80%) accounted for the most substantial proportion of HAIs, followed by bloodstream infections (15.74%), and urinary tract infection (12.69%). A summer peak in HAIs was detected among adult and elderly patients.ConclusionsThis study shows how continuous electronic incidence surveillance based on existing hospital electronic databases can provide a practical means of measuring hospital-wide HAI incidence. The estimated incidence trends demonstrate the necessity for improved infection control measures related to bloodstream infections, ventilator-associated pneumonia, non-intensive care patients, and non-device-associated HAIs, especially during summer months.

Comparison of the efficacy of nafcillin and glycopeptides as definitive therapy for patients with methicillin-susceptible Staphylococcus aureus bacteremia: a retrospective cohort study

BackgroundStudies have shown that the prognosis of the treatment of methicillin-susceptible S. aureus (MSSA) with glycopeptides is inferior compared to treatment with β-lactam. However, there are only few studies comparing treatment with antistaphylococcal penicillin alone to glycopeptide treatment. The aim of this study was to compare the efficacy of nafcillin, an antistaphylococcal penicillin, with that of glycopeptides as a definitive therapy for MSSA bacteremia.MethodsPatients with MSSA bacteremia recruited from a tertiary referral hospital were enrolled in this retrospective cohort study. Demographic characteristics, laboratory data, and clinical outcome of the treatment were compared between a group receiving nafcillin and a group receiving glycopeptides.ResultsA total of 188 patients with MSSA bacteremia were included in this study. The glycopeptide group had a higher rate of malignancy (28.6 vs. 60.8%, p < 0.001) and proportion of healthcare-associated infections (47.3 vs. 72.2%, p < 0.001) compared to the nafcillin group. The ratio of skin and soft tissue infections (30.0 vs. 16.7%, p = 0.037) and bone and joint infections (17.8 vs. 6.3%, p = 0.022), as well as levels of C-reactive protein (139.60 vs. 107.61 mg/dL, p = 0.022) were higher in the nafcillin group. All-cause 28-day mortality was significantly high in the glycopeptide group (7.7 vs. 20.6%, p = 0.013).ConclusionIn patients with MSSA bacteremia, all-cause 28-day mortality rate was higher in a group treated with glycopeptides than in a group treated with nafcillin. Therefore, the use of nafcillin should be considered as a definitive therapy for MSSA bacteremia.

Effects of implementation of an online comprehensive antimicrobial-stewardship program in ICUs: A longitudinal study.

The long-term effects of antimicrobial-stewardship programs in the intensive care units (ICUs) have not been adequately examined. We evaluated the impact of an online comprehensive antimicrobial stewardship program (OCASP) on the outcomes of patients in 200-bed medical/surgical ICUs over the course of 11years. We analyzed the records of adult patients admitted to ICUs during the 5years before (n=27,499) and the 6years after (n=33,834) implementation of an OCASP. Antimicrobial consumption, expenditures, duration of treatment, incidence of healthcare-associated infections (HAIs), prevalence of HAIs caused by antimicrobial-resistant strains, and crude or sepsis-related mortality of patients were analyzed. Segmented regression analyses of interrupted time series were used to assess the significance of changes in antimicrobial use. Compared to the patients in the pre-OCASP period, the patients in the post-OCASP period were older, had greater disease severity, longer ICU stays, and were more likely to receive antimicrobials, but had lower antimicrobial expenditures and crude and sepsis-related mortality. The trend of overall antimicrobial use [slope of defined daily dose/1000 patient-days vs. time) increased significantly before OCASP implementation (p<0.001), but decreased significantly after implementation (p<0.01). The administration duration of all classes of antibiotics were significantly shorter (p<0.001) and the incidences of HAIs were significantly lower (p<0.001) after implementation. However, there was an increase in the proportion of HAIs caused by carbapenem-resistant Acinetobacter baumannii relative to all A. baumannii infections. Implementation of an OCASP in the ICUs reduced antimicrobial consumption and expenditures, but did not compromise healthcare quality.

Estimated hospital costs associated with preventable health care-associated infections if health care antiseptic products were unavailable.

ObjectivesHealth care-associated infections (HAIs) pose a significant health care and cost burden. This study estimates annual HAI hospital costs in the US avoided through use of health care antiseptics (health care personnel hand washes and rubs; surgical hand scrubs and rubs; patient preoperative and preinjection skin preparations).MethodsA spreadsheet model was developed with base case inputs derived from the published literature, supplemented with assumptions when data were insufficient. Five HAIs of interest were identified: catheter-associated urinary tract infections, central line-associated bloodstream infections, gastrointestinal infections caused by Clostridium difficile, hospital- or ventilator-associated pneumonia, and surgical site infections. A national estimate of the annual potential lost benefits from elimination of these products is calculated based on the number of HAIs, the proportion of HAIs that are preventable, the proportion of preventable HAIs associated with health care antiseptics, and HAI hospital costs. The model is designed to be user friendly and to allow assumptions about prevention across all infections to vary or stay the same. Sensitivity analyses provide low- and high-end estimates of costs avoided.ResultsLow- and high-end estimates of national, annual HAIs in hospitals avoided through use of health care antiseptics are 12,100 and 223,000, respectively, with associated hospital costs avoided of US$142 million and US$4.25 billion, respectively.ConclusionThe model presents a novel approach to estimating the economic impact of health care antiseptic use for HAI avoidance, with the ability to vary model parameters to reflect specific scenarios. While not all HAIs are avoidable, removing or limiting access to an effective preventive tool would have a substantial impact on patient well-being and infection costs. HAI avoidance through use of health care antiseptics has a demonstrable and substantial impact on health care expenditures; the costs here are exclusive of administrative penalties or long-term outcomes for patients and caregivers such as lost productivity or indirect costs.

Healthcare-Associated Influenza in Canadian Hospitals from 2006 to 2012

To determine trends, patient characteristics, and outcome of patients with healthcare-associated influenza in Canadian hospitals. Prospective surveillance of laboratory-confirmed influenza among hospitalized adults was conducted from 2006 to 2012. Adults with positive test results at or after admission to the hospital were assessed. Influenza was considered to be healthcare associated if symptom onset was equal to or more than 96 hours after admission to a facility or if a patient was readmitted less than 96 hours after discharge or admitted less than 96 hours after transfer from another facility. Baseline characteristics of influenza patients were collected. Patients were reassessed at 30 days to determine the outcome. Acute care hospitals participating in the Canadian Nosocomial Infection Surveillance Program. A total of 570 (17.3%) of 3,299 influenza cases were healthcare associated; 345 (60.5%) were acquired in a long-term care facility (LTCF), and 225 (39.5%) were acquired in an acute care facility (ACF). There was year-to-year variability in the rate and proportion of cases that were healthcare associated and variability in the proportion that were acquired in a LTCF versus an ACF. Patients with LTCF-associated cases were older, had a higher proportion of chronic heart disease, and were less likely to be immunocompromised compared with patients with ACF-associated cases; there was no significant difference in 30-day all-cause and influenza-specific mortality. Healthcare-associated influenza is a major component of the burden of disease from influenza in hospitals, but the proportion of cases that are healthcare associated varies markedly from year to year, as does the proportion of healthcare-associated infections that are acquired in an ACF versus an LTCF.

Results from the second Scottish national prevalence survey: the changing epidemiology of healthcare-associated infection in Scotland

Healthcare-associated infections (HAIs) are a recognized public health problem worldwide. Point prevalence surveys (PPSs) can be used to measure the burden of all HAI types. To measure the prevalence of HAI and determine any changes in the epidemiology of HAI since the first Scottish national PPS. A national rolling PPS in National Health Service (NHS) acute, NHS non-acute, NHS paediatric and independent hospitals was carried out during September and October 2011 using the European Centre for Disease Prevention and Control protocol designed for the European PPS. The prevalence of HAI and distribution of HAI types were measured and the results compared with the first Scottish national HAI point prevalence survey of 2005/2006. The prevalence of HAI was 4.9%, 2.5%, 6.1% and 1.2% in acute, non-acute, paediatric and independent hospitals respectively. The prevalence of HAI was significantly higher in acute hospitals compared with non-acute hospitals. There were no significant differences between the prevalence in the other hospital types. The prevalence of HAI in acute and non-acute hospitals was lower than the first survey by approximately one-third. The proportion of HAIs that were urinary tract infection, surgical site infection and bloodstream infection was higher and the proportion that were gastrointestinal including Clostridium difficile infection was lower in acute hospitals compared with the previous survey. The epidemiology of HAI has changed in Scotland since the first national survey in 2005/2006, thus infection prevention and control measures require to be refocused in this regard. The lower prevalence and changing epidemiology of HAI in acute and non-acute care suggest that there may be a temporal relationship with the implementation of the national programme of targeted HAI interventions in the intervening period.

Diagnosis, prevention and treatment of fungal infections

Most fungi live harmlessly in the environment, but some species can cause disease in the human host. Nurses working in primary care are likely to see patients with superficial fungal infections and are well placed to offer advice about treatment and measures to prevent the spread of infection in the home. Patients with weakened immune function admitted to hospital are at high risk of developing serious, invasive fungal infections. Systemic fungal infections are a major problem among critically ill patients in acute care settings and are responsible for an increasing proportion of healthcare-associated infections.
