Hand hygiene improvement of individual healthcare workers: results of the multicentre PROHIBIT study.

BACKGROUND: Traditionally, hand hygiene (HH) interventions do not identify the observed healthcare workers (HWCs) and therefore, reflect HH compliance only at population level. Intensive care units (ICUs) in seven European hospitals participating in the "Prevention of Hospital Infections by Intervention and Training" (PROHIBIT) study provided individual HH compliance levels. We analysed these to understand the determinants and dynamics of individual change in relation to the overall intervention effect. METHODS: We included HCWs who contributed at least two observation sessions before and after intervention. Improving, non-changing, and worsening HCWs were defined with a threshold of 20% compliance change. We used multivariable linear regression and spearman's rank correlation to estimate determinants for the individual response to the intervention and correlation to overall change. Swarm graphs visualized ICU-specific patterns. RESULTS: In total 280 HCWs contributed 17,748 HH opportunities during 2677 observation sessions. Overall, pooled HH compliance increased from 43.1 to 58.7%. The proportion of improving HCWs ranged from 33 to 95% among ICUs. The median HH increase per improving HCW ranged from 16 to 34 percentage points. ICU wide improvement correlated significantly with both the proportion of improving HCWs (ρ = 0.82 [95% CI 0.18-0.97], and their median HH increase (ρ = 0.79 [0.08-0.97]). Multilevel regression demonstrated that individual improvement was significantly associated with nurse profession, lower activity index, higher nurse-to-patient ratio, and lower baseline compliance. CONCLUSIONS: Both the proportion of improving HCWs and their median individual improvement differed substantially among ICUs but correlated with the ICUs' overall HH improvement. With comparable overall means the range in individual HH varied considerably between some hospitals, implying different transmission risks. Greater insight into improvement dynamics might help to design more effective HH interventions in the future.

Mortality review as a tool to assess the contribution of healthcare-associated infections to death: results of a multicentre validity and reproducibility study, 11 European Union countries, 2017 to 2018.

IntroductionThe contribution of healthcare-associated infections (HAI) to mortality can be estimated using statistical methods, but mortality review (MR) is better suited for routine use in clinical settings. The European Centre for Disease Prevention and Control recently introduced MR into its HAI surveillance.AimWe evaluate validity and reproducibility of three MR measures.MethodsThe on-site investigator, usually an infection prevention and control doctor, and the clinician in charge of the patient independently reviewed records of deceased patients with bloodstream infection (BSI), pneumonia, Clostridioides difficile infection (CDI) or surgical site infection (SSI), and assessed the contribution to death using 3CAT: definitely/possibly/no contribution to death; WHOCAT: sole cause/part of causal sequence but not sufficient on its own/contributory cause but unrelated to condition causing death/no contribution, based on the World Health Organization's death certificate; QUANT: Likert scale: 0 (no contribution) to 10 (definitely cause of death). Inter-rater reliability was assessed with weighted kappa (wk) and intra-cluster correlation coefficient (ICC). Reviewers rated the fit of the measures.ResultsFrom 2017 to 2018, 24 hospitals (11 countries) recorded 291 cases: 87 BSI, 113 pneumonia , 71 CDI and 20 SSI. The inter-rater reliability was: 3CAT wk 0.68 (95% confidence interval (CI): 0.61-0.75); WHOCAT wk 0.65 (95% CI: 0.58-0.73); QUANT ICC 0.76 (95% CI: 0.71-0.81). Inter-rater reliability ranged from 0.72 for pneumonia to 0.52 for CDI. All three measures fitted 'reasonably' or 'well' in > 88%.ConclusionFeasibility, validity and reproducibility of these MR measures was acceptable for use in HAI surveillance.

Mortality Following Clostridioides difficile Infection in Europe: A Retrospective Multicenter Case-Control Study.

We aimed to describe the clinical presentation, treatment, outcome and report on factors associated with mortality over a 90-day period in Clostridioides difficile infection (CDI). Descriptive, univariate, and multivariate regression analyses were performed on data collected in a retrospective case-control study conducted in nine hospitals from seven European countries. A total of 624 patients were included, of which 415 were deceased (cases) and 209 were still alive 90 days after a CDI diagnosis (controls). The most common antibiotics used previously in both groups were ß-lactams; previous exposure to fluoroquinolones was significantly (p = 0.0004) greater in deceased patients. Multivariate logistic regression showed that the factors independently related with death during CDI were older age, inadequate CDI therapy, cachexia, malignancy, Charlson Index, long-term care, elevated white blood cell count (WBC), C-reactive protein (CRP), bacteraemia, complications, and cognitive impairment. In addition, older age, higher levels of WBC, neutrophil, CRP or creatinine, the presence of malignancy, cognitive impairment, and complications were strongly correlated with shortening the time from CDI diagnosis to death. CDI prevention should be primarily focused on hospitalised elderly people receiving antibiotics. WBC, neutrophil count, CRP, creatinine, albumin and lactate levels should be tested in every hospitalised patient treated for CDI to assess the risk of a fatal outcome.

Negative pressure wound therapy of Corynebacterium jeikeium associated granulomatous mastitis.

We present the first Corynebacterium associated therapy resistant granulomatous mastitis successfully treated with negative pressure wound therapy (NPWT). Our patient had received five different courses of antibiotic therapy, and three surgical explorations before NPWT was introduced and resulted in healing. For a successful treatment, the use of targeted antibiotic therapy, steroid therapy and in case of progressive disease, wide excision is required. When this results in a large wound cavity, NPWT seems an effective and innovative option.

Prevention of hospital infections by intervention and training (PROHIBIT): results of a pan-European cluster-randomized multicentre study to reduce central venous catheter-related bloodstream infections.

PURPOSE: To test the effectiveness of a central venous catheter (CVC) insertion strategy and a hand hygiene (HH) improvement strategy to prevent central venous catheter-related bloodstream infections (CRBSI) in European intensive care units (ICUs), measuring both process and outcome indicators. METHODS: Adult ICUs from 14 hospitals in 11 European countries participated in this stepped-wedge cluster randomised controlled multicentre intervention study. After a 6 month baseline, three hospitals were randomised to one of three interventions every quarter: (1) CVC insertion strategy (CVCi); (2) HH promotion strategy (HHi); and (3) both interventions combined (COMBi). Primary outcome was prospective CRBSI incidence density. Secondary outcomes were a CVC insertion score and HH compliance. RESULTS: Overall 25,348 patients with 35,831 CVCs were included. CRBSI incidence density decreased from 2.4/1000 CVC-days at baseline to 0.9/1000 (p < 0.0001). When adjusted for patient and CVC characteristics all three interventions significantly reduced CRBSI incidence density. When additionally adjusted for the baseline decreasing trend, the HHi and COMBi arms were still effective. CVC insertion scores and HH compliance increased significantly with all three interventions. CONCLUSIONS: This study demonstrates that multimodal prevention strategies aiming at improving CVC insertion practice and HH reduce CRBSI in diverse European ICUs. Compliance explained CRBSI reduction and future quality improvement studies should encourage measuring process indicators.

[Necrotizing fasciitis in head and neck area]. / Nekrotizáló fasciitis a fej-nyaki régióban.

Necrotizing fasciitis is a fulminant infection of the deeper layers of skin and subcutaneous tissues characterized by progressive soft tissue necrosis and high mortality. It rarely occurs in the head and neck area. The clinical picture includes non-specific but typical local and systemic symptoms. The treatment is a complex, multidisciplinary task which includes radical surgical exploration, debridement and drainage, empirically started and then targeted intravenous antibiotics and supportive therapy. Authors report a case of necrotizing fasciitis localized on the right side of the face which caused multi-organ failure and phlegmone of the neck.

[Examination of maternal extended spectrum beta-lactamase bacterial colonization and follow-up of newborns requiring Neonatal Intensive Care Unit admission]. / Neonatális Intenzív Centrumban ellátást igénylo betegeink anyai széles spektrumú béta-laktamáz-termelo baktériummal történt kolonizációjának vizsgálata és követése.

INTRODUCTION: The extended beta-lactamase producing Enterobacteriaceae may cause asymptomatic carriage if present in the colon of premature infants or pregnant women. AIM: To assess the incidence of colonization among mothers whose infants were admitted to Neonatal Intensive Center on the day of their delivery for this pathogen. METHOD: From October 1, 2013 until October 31, 2015 the authors screened mothers on the day of their delivery for this pathogen. Nineteen of the 751 anorectal swabs or stool samples were found to be positive. Mothers having positive samples were given personal education for hand hygiene, then they actively participated in the care of their babies. From some premature infants ear swab and stomach washing were taken and sent for culture on the day of their admission. In the course of their hospital stay, anorectal swabs were taken and screened for this bacteria colonization at least once. RESULTS: None of the premature infants of the 19 extended beta-lactamase producing Enterobacteriaceae-positive mothers became positive in the studied period. CONCLUSION: If the mother is colonized, the spreading of pathogen to newborns can be prevented by observing the hygienic rules. Orv. Hetil., 2016. 157(34), 1353-1356.

Retrospective health-care associated infection surveillance in oral and maxillofacial reconstructive microsurgery.

In polymorbid or anaemic patients who receive preoperative radiotherapy or undergo long duration surgery involving potentially infectious sites, perioperative antibiotic prophylaxis (PAP) that is effective against normal oral bacterial flora is mandatory and plays an important role in preventing postoperative infection. In a four-year retrospective analysis, the incidence, outcome, and the efficacy of PAP were evaluated in patients treated at the Department of Oral and Maxillofacial Surgery and Otorhinolaryngology at Kecskemét Hospital. The results were compared with data from the literature to determine if the use of PAP was adequate at the Department.During the study period (between 01/09/2007 and 31/01/2011) 108 patients were evaluated. The mean duration of prophylactic antibiotic treatment was 8.3 ± 5.2 days, with cefotaxime+metronidazole being the most commonly used combination. Surgical site infection occurred in 8 patients (7.5%) in the clean-contaminated category.Our results showed that the perioperative antibiotic prophylaxis administered at our Department was efficient and effective against the oral bacterial flora of patients. Its use is recommended in head and neck microsurgery. To avoid development of antibiotic resistance and to reduce costs, it seems that the duration of antibiotic regimen for primary surgery can be reduced from 8.3 ± 5.2 days to 3 days.

Petroleum jelly-induced penile paraffinoma with inguinal lymphadenitis mimicking incarcerated inguinal hernia.

Chronic granulomatous inflammation may develop after injecting foreign oily substances into the penis. The disorder affects mainly the site of administration, but regional lymphadenopathy or even systemic disease can occur. We present a 39-year-old man with petroleum jelly-induced penile lesion and unilateral inguinal lymphadenitis mimicking incarcerated inguinal hernia. At hernioplasty no hernial sac was found, but enlarged lymph nodes suspicious for malignancy were identified. The histopathologic findings of these nodes were consistent with mineral oil granuloma. Paraffinoma of the male genitalia can cause various clinical features posing a differential diagnostic dilemma. Regional lymphadenitis may be the main clinical characteristic. Patient's history, physical and histopathological examination are required to establish the diagnosis.

Curiosities of the methicillin-resistant Staphylococcus aureus survey - possibility of pseudo-outbreak and transmission to household contacts.

Methicillin-resistant Staphylococcus aureus (MRSA) is currently one of the most prevalent antibiotic-resistant pathogens in hospitals, but it is also emerging as a community-acquired pathogen. We analysed the clinical and microbiological data of the patients in a county teaching hospital regarding MRSA. During the examination period (1996-2010), four outbreaks and one pseudo-outbreak occurred. It also became evident that health care workers and their families are possibly at risk of becoming carriers of MRSA. The importance of the molecular epidemiological investigation (pulsed-field gel-electrophoresis (PFGE)) typing and hygienic measures in order to detect and control MRSA outbreaks must be emphasised. Following infection control guidelines seems to be cost-effective method of controlling the nosocomial transmission of MRSA.

[Aspergillus peritonitis--a case report]. / Aspergillus peritonitis esete.

The incidence of fungal infections such as Aspergillosis is increasing among immunocompromised patients. Demand for diagnosis of mycotic diseases is steadily raising among clinicians and treatment of these patients represents a continually growing challenge. The authors present a case of a 53-year-old male patient with Aspergillus peritonitis. This case deserves attention because its extreme rarity in the medical literature and complex therapy of coinfections during the hospital stay which was difficult and relatively expensive. The importance of consultation and microbiological sampling is emphasized.
