[Tuberculosis among children and young adults in Emilia-Romagna Region (Northern Italy): surveillance system and integration with socioeconomic data]. / La tubercolosi nei bambini e nei giovani adulti in Emilia-Romagna: sistema di sorveglianza e integrazione con dati socioeconomici.

OBJECTIVES: to characterise the cases of tuberculosis (TB) aged 0-24 years reported in Emilia-Romagna (Northern Italy) Region between 2001 and 2010 through an ecological approach and from a sociodemographic perspective. DESIGN: observational study on notified TB cases, with data integration and subsequent location through geocoding and ecological deprivation index. SETTING AND PARTICIPANTS: notification records of TB cases identified by the current surveillance system. Cases were geocoded where address details were available and, through spatial intersection with census block polygons, the related deprivation index (DI) was attributed to them. MAIN OUTCOME MEASURES: deprivation index distribution of the observed cases. RESULTS: in the considered decade, 686 cases of tuberculosis in the age group 0-24 years were reported, 14.5% of the overall number of cases in the Emilia-Romagna Region. The DI was attributed to the 90.4% of cases. Notified TB cases were more frequently located in the most deprived areas. CONCLUSIONS: as other TB international surveillance systems, this study shows that it is possible to locate TB cases, to link them with census data and, therefore, to characterise with socioeconomic information. Looking ahead, the extension of the analysis to all age classes, the updating of socioeconomic data and the use of qualitative methodologies can integrate surveillance system data to better describe the social disadvantage among TB cases.

Staphylococcus aureus in a northern Italian region: phenotypic and molecular characterization.

BACKGROUND: Staphylococcus aureus is a leading cause of community-acquired infections and healthcare-associated infections. Epidemiological data are useful for understanding the dynamics of the diffusion of this pathogen, and to plan control activities and monitor their efficacy. METHODS: S. aureus isolates were collected in 13 public hospital laboratories of Emilia-Romagna (northern Italy region) during February-March 2009; phenotypic and molecular characterizations of these isolates were performed. RESULTS: The study sample included 267 isolates, 57 from blood, 81 from respiratory tract, and 129 from wounds; 106 (40%) were methicillin-resistant S. aureus (MRSA). MRSA showed a limited number of circulating clones with 2 predominant spa types--t008 and t041--accounting for 36% and 27% of MRSA isolates, respectively. The t041 type had a higher prevalence of antimicrobial resistance compared to other spa types and accounted for most of the retrieved hetero-vancomycin-intermediate S. aureus (h-VISA), while t008 was more frequently detected in non-hospital isolates. A higher degree of genetic diversity was observed in methicillin-susceptible S. aureus (MSSA), with no predominant clones and low prevalence of antimicrobial resistance. The occurrence of community-acquired MRSA infection appears to be rare in Emilia-Romagna. CONCLUSIONS: In contrast to previous studies reporting Italian data, t008 was the most frequent spa type among MRSA isolates in Emilia-Romagna. The prevalence of antimicrobial resistance of different MRSA spa types could influence their ability to cause infections with hospital onset. The presence of only 2 major MRSA clones circulating in Emilia-Romagna increases the chances that a regional strategy aimed at MRSA prevention will be effective.

Why do paediatricians prescribe antibiotics? Results of an Italian regional project.

BACKGROUND: To investigate determinants of antibiotic prescription in paediatric care, as a first step of a multilevel intervention to improve prescribing for common respiratory tract infections (RTIs) in a northern Italian region with high antibiotic prescription rate. METHODS: A two-step survey was performed: in phase I, knowledge, and attitudes were explored involving all family and hospital paediatricians of Emilia-Romagna and a sample of parents. In phase II, patient care practices were explored in a stratified random sample of visits, both in hospitals and family physician's clinics; parent expectations were investigated in a sub-sample of these visits. RESULTS: Out of overall 4352 visits for suspected RTIs, in 38% of children an antibiotic was prescribed. Diagnostic uncertainty was perceived by paediatricians as the most frequent cause of inappropriate prescription (56% of 633 interviewed paediatricians); but, rapid antigen detecting tests was used in case of pharyngitis/pharyngotonsillitis by 36% and 21% of family and hospital paediatricians only. More than 50% of paediatricians affirmed to not adopt a "wait and see strategy" in acute otitis. The perceived parental expectation of antibiotics was not indicated by paediatricians as a crucial determinant of prescription, but this perception was the second factor most strongly associated to prescription (OR = 12.8; 95% CI 10.4-15.8), the first being the presence of othorrea. Regarding parents, the most important identified factors, potentially associated to overprescribing, were the lack of knowledge of RTIs and antibiotics (41% of 1029 parents indicated bacteria as a possible cause of common cold), and the propensity to seek medical care for trivial infections (48% of 4352 children accessing ambulatory practice presented only symptoms of common cold). CONCLUSION: A wide gap between perceived and real determinants of antibiotic prescription exists. This can promote antibiotic overuse. Inadequate parental knowledge can also induce inappropriate prescription. The value of this study is that it simultaneously explored determinants of antimicrobial prescribing in an entire region involving both professionals and parents.

Healthcare-related infections outside the hospital: a new frontier for infection control.

In all industrialized countries, an increasing number of persons are cared for outside the acute hospitals: thus, infection control programs should be adapted to the new scenario. This paper briefly reviews the epidemiological features of infections acquired outside the acute care hospital, focusing on residential homes for the elderly. An intervention study aimed at reducing the healthcare associated infections in 22 residential facilities in Emilia-Romagna region is described.
