Antibiotic treatments for children ages 0-23 months in a northern Italy region: a cohort study.

BACKGROUND: This study aims to describe the pattern of antibiotic treatments in the community for children ages 0-23 months in Emilia-Romagna (a northern Italy region) pointing out possible changes of prescribed agents when first treatments in the life of each children are compared to successive ones. MATERIALS AND METHODS: The Regional Drug Prescription and the Resident Population databases were used as data sources to study the cohort of children born between January 1 and December 31, 2000 and resident in Emilia-Romagna. RESULTS: The cumulative incidences of children with at least one treatment were 22%, 55% and 82% at 6, 12 and 24 months of age, respectively. Broad spectrum penicillins were the most prescribed antibiotic class for children at their first treatment while cephalosporins were the most prescribed class for successive treatments and when pooling all treatments. CONCLUSION: Cephalosporins and other second line antibiotics are frequently prescribed to 0 to 23-month-old residents in Emilia-Romagna even when only first treatments are considered; further research is needed to quantify inappropriateness of antibiotic prescription.

Delay in the treatment of pulmonary TB in a changing demographic scenario.

OBJECTIVE: To quantify patient and health care delays in the treatment of pulmonary tuberculosis (PTB) in Emilia-Romagna region, Italy, and to study the association between migration status and delay. DESIGN: All patients with symptomatic PTB, aged >15 years, who were notified in Emilia-Romagna during 2003 and were alive at time of data collection, were included. An individual form was completed for each notified patient by the local health authority officer in charge of surveillance data. RESULTS: Median patient delay, health care delay and total delay were 7, 36 and 65 days, respectively. Recent migrants (stay in Italy < or = 3 years) had the longest patient delay (16 days), while Italian patients had the longest health care delay (60 days). Migration status was independently associated with both patient and health care delay, although the direction of association changed according to which delay was considered. CONCLUSION: Public health interventions aiming to reduce delay in treatment of PTB should improve the access of recent migrants to health care and increase suspicion of TB among Italian patients. Studies on delays in treatment of TB should investigate patient delay and health care delay as distinct outcomes.

Barriers to effective tuberculosis control: a qualitative study.

SETTING: Emilia Romagna region, Italy. OBJECTIVE: To explore chest and infectious disease physicians' views of barriers to effective tuberculosis (TB) control and possible solutions. DESIGN: A series of nine focus groups including a total of 49 physicians. RESULTS: Three categories of barriers to effective TB control were identified: 1) uncertainty about appropriate clinical practice in the treatment of specific sub-groups of patients, such as the elderly or immigrants; 2) organisational factors, such as the availability of diagnostic services and of sufficient resources; and 3) multiple barriers to a viable and effective TB control programme in a country with a low prevalence of TB. CONCLUSIONS: The lack of integration and coordination of health services, as well as the scarcity of dedicated TB nurses, were perceived by the participants as crucial barriers to effective TB control. As a result of this study, a regional programme was started with the goals of quantifying the need for TB nurses and developing a better network for required health services. Qualitative studies such as this can be useful in improving TB control in a low-prevalence TB country, to identify problems and increase the participation of key professionals.

The geographic relationship between the use of antimicrobial drugs and the pattern of resistance for Streptococcus pneumoniae in Italy.

OBJECTIVES: A temporal relationship between the increasing use of antibiotics and the increasing levels of antibiotic resistance has been established for Streptococcus pneumoniae. There are also data that support the presence of a geographic correlation between the level of resistance and the pattern of use among different countries and even within the same country. The aim of this study was to evaluate the potential geographic correlation between the use of beta-lactams and erythromycin in different Italian regions and the resistance of these antibiotics to invasive strains of S. pneumoniae during the period 1999-2000. METHODS: Ecological study. RESULTS: In Italy the mean level of resistance for penicillin and erythromycin was 11.4% and 28.9%, respectively. The highest level of resistance for both antibiotics was observed in central and southern regions (i.e. Campania, Lazio and the combined regions of Calabria, Puglia and Sicilia). These regions were also those with the highest consumption of antibiotics. A strong correlation was found between the prevalence of resistance to erythromycin and the regional use of macrolides (r=0.93, P=0.001) and beta-lactams (r=0.84, P=0.002). With regard to penicillin resistance, the greatest correlation was observed for oral penicillin (r=0.85, P=0.002). CONCLUSION: Our study provides further evidence of the association between regional level of antibiotic use and prevalence of antibiotic resistance.

Quality of local guidelines for surgical antimicrobial prophylaxis.

Surgical antimicrobial prophylaxis (AMP) is an effective measure to prevent surgical site infections. To determine the quality and availability of local guidelines for AMP, a survey was conducted in the public hospitals of a Northern Italian region. The guidelines for "Antimicrobial Prophylaxis in Surgery" by the Scottish Intercollegiate Guidelines Network (SIGN) were used as a standard by which the quality of the local guidelines was compared. The coverage of surgical specialities by local AMP guidelines was 93.1% for hospitals where guidelines had been developed at hospital level and 47% for hospitals where guidelines had been developed by individual surgical departments. Local guidelines recommended AMP for most surgical procedures (96%), including procedures with evidence against the use of antimicrobial prophylaxis (87% of these procedures). Only 8% of all procedure-specific guidelines (PSG) recommended an incorrect timing of AMP (not administering AMP at the induction of anaesthesia), while 41% recommended an incorrect duration (additional antimicrobial doses after completion of the surgical operation). This survey showed that having written protocols at local level does not necessarily mean they comply with available scientific evidence. Thus, the quality of local guidelines needs to be improved.

Can hospital discharge diagnoses be used for surveillance of surgical-site infections?

The aim of this study was to assess the data quality of postoperative infections in a hospital discharge registry in the Emilia-Romagna region of Italy. Data from a prospective regional study of postoperative infections in 6158 patients from 31 of the 36 public hospitals of the region were compared with data from the regional hospital discharge registry, using different classes of ICD-9-CM codes. The sensitivity of the hospital discharge database for postoperative surgical infections was 10% when ICD-9-CM codes directly indicative of postoperative infectious complications were used. When non-specific codes of postoperative complications, not necessarily of infectious origin, were added, the sensitivity reached 21%. At present, the hospital discharge registry is not suited for surveillance of hospital-acquired infection.

Antibiotic prescriptions in children.

OBJECTIVES: The aim of this study was to evaluate antibiotic prescription for children in Emilia Romagna, a Northern Italian region with 414 880 people aged 1-14 years. METHODS: The regional Prescription Database of drugs reimbursed by the Italian National Health Service was used in this study. Antibiotic use was estimated as the proportion of children who received at least one prescription during the year 2000 (number of children treated per 100 inhabitants per year). To evaluate the frequency of exposure for each child, all the prescriptions given within a period shorter than 12 days were considered as a single treatment. RESULTS: In the year surveyed, 511,270 antibiotic prescriptions in 219,257 children were identified. In all, 52.9% of children received at least one antibiotic; this percentage decreased with age, ranging from 70.4% in children 1-2 years old to 35.8% in children >11 years old. Fifty-two per cent of inhabitants under the age of 15 years were treated with systemic antibiotics at least once in the year. Cephalosporins were mostly prescribed in the youngest children, while macrolides were most frequently used in children over 6 years old. In all 3.9% of children were treated with topical antibiotics. CONCLUSIONS: This study has shown that paediatric antibiotic prescription rates can be derived from analysis of regional drug and resident databases. High antibiotic usage is shown in the paediatric population of Emilia Romagna, similar to that observed in other regions of Northern Italy. Broad-spectrum antibiotics are predominantly prescribed. Comparison with prescription rates from other countries' paediatric populations suggests there is extensive antibiotic overuse in Italy. This could be associated with selection for and dissemination of antibiotic resistance. Interventions are needed to reduce consumption.

Antibiotic policies in Italian hospitals: still a lot to achieve.

A national survey was conducted using a mailed questionnaire in 2000 to quantify the prevalence in Italian hospitals of policies aimed to reduce the emergence and dissemination of resistant strains. The study population consisted of all of the Italian teaching and research hospitals, as well as all public hospitals with 300 beds or more; a 50% random sample of public hospitals smaller than 300 beds was selected. The overall response rate was 80% (428/535). Of the respondents, 9.6% claimed to have implemented a surveillance system of antimicrobial resistance and to be able to identify repeated isolations; 90% had a hospital formulary in place, 50% had a pharmacy committee, and 18% had an antibiotic policy subcommittee that met at least once a year in 1999. Forty-one percent implemented restriction policies based on written justifications for antibiotics, and 8% provided susceptibility results for first line antibiotics only. Antibiotic consumption was monitored by using the Defined Daily Dose, as a unit of measure, in 11% of the cases. Of the respondent hospitals, 251 (58.6%) claimed to have defined clinical practice guidelines for handwashing, 156 (36.4%) for isolation procedures, and seven (1.6%) for the control of methicillin-resistant Staphylococcus aureus (MRSA) infections. Our data demonstrates that intensive efforts are necessary to understand barriers better to change and to identify solutions to adopt uniform, comprehensive policies for antimicrobial resistance in Italy.

Two-year population-based molecular epidemiological study of tuberculosis transmission in the metropolitan area of Milan, Italy.

A 2-year, population-based, molecular epidemiological study was conducted in Milan, Italy, to determine the proportion of tuberculosis (TB) cases attributable to recent transmission. All strains were typed by restriction fragment length polymorphism (RFLP) analysis; clustering was considered indicative of recent transmission. Of the 581 cases, 239 (41.1%) belonged to clusters that consisted of 2 to 11 patients; 28.1% were attributable to recent transmission (number of clustered patients minus 1). Clustering was associated with multidrug-resistant Mycobacterium tuberculosis strains (74.2% of cases), AIDS (60.2%), and a history of incarceration (67.4%). The frequency of multidrug-resistant Mycobacterium tuberculosis was 5.3% overall (15.4% among AIDS patients). Among AIDS patients, infection with a resistant strain was independently associated with clustering (odds ratio, 1.32; 95% confidence interval, 1.07-1.163), while among non-AIDS patients, three factors were associated with clustering: history of incarceration (odds ratio, 2.03; 95% confidence interval, 1.41-2.92), age <30 years (odds ratio, 1.43; 95% confidence interval, 1.05-1.94), and native-born Italian nationality (odds ratio, 1.44; 95% confidence interval, 1.08-1.92). Of the 118 patients who belonged to either the smallest or the largest cluster, 19 (16.1%) reported an epidemiological link with another study patient. The results of this study highlight the need for control programs that focus on selected high-risk groups consisting primarily of HIV-infected individuals and persons with social and lifestyle risks for TB. These programs should be aimed at reducing the probability of transmission of drug-resistant TB through early identification of cases and provision of effective treatment until the individual is cured.

Predictors of failure of noninvasive positive pressure ventilation in patients with acute hypoxemic respiratory failure: a multi-center study.

CONTEXT: In patients with hypoxemic acute respiratory failure (ARF), randomized studies have shown noninvasive positive pressure ventilation (NPPV) to be associated with lower rates of endotracheal intubation. In these patients, predictors of NPPV failure are not well characterized. OBJECTIVE: To investigate variables predictive of NPPV failure in patients with hypoxemic ARF. DESIGN: Prospective, multicenter cohort study. SETTING: Eight Intensive Care Units (ICU) in Europe and USA. PATIENTS: Of 5,847 patients admitted between October 1996 and December 1998, 2,770 met criteria for hypoxemic ARF. Of these, 2,416 were already intubated and 354 were eligible for the study. RESULTS: NPPV failed in 30% (108/354) of patients. The highest intubation rate was observed in patients with ARDS (51%) or community-acquired pneumonia (50%). The lowest intubation rate was observed in patients with cardiogenic pulmonary edema (10%) and pulmonary contusion (18%). Multivariate analysis identified age > 40 years (OR 1.72, 95% CI 0.92-3.23), a simplified acute physiologic score (SAPS II) > or = 35 (OR 1.81, 95% CI 1.07-3.06), the presence of ARDS or community-acquired pneumonia (OR 3.75, 95% CI 2.25-6.24), and a PaO2:FiO2 < or = 146 after 1 h of NPPV (OR 2.51, 95% CI 1.45-4.35) as factors independently associated with failure of NPPV. Patients requiring intubation had a longer duration of ICU stay ( P < 0.001), higher rates of ventilator-associated pneumonia and septic complications ( P < 0.001), and a higher ICU mortality ( P < 0.001). CONCLUSIONS: In hypoxemic ARF, NPPV can be successful in selected populations. When patients have a higher severity score, an older age, ARDS or pneumonia, or fail to improve after 1 h of treatment, the risk of failure is higher.

Nosocomial necrotising enterocolitis outbreaks: epidemiology and control measures.

UNLABELLED: Necrotising enterocolitis (NEC) is one of the most serious gastrointestinal diseases among newborns and it mainly affects those in intensive care units. The aetiology of the disease has been reported to be multifactorial and both sporadic cases and nosocomial outbreaks have occurred. In this report, we review 17 epidemics of NEC reported in the literature between 1973 and 1999. The number of confirmed cases ranged from 1 to 32 with an average of 10.5 confirmed cases. On average, 16.15% of cases required surgery (range 0-66.6%). The average mortality rate was 6.25% (range 0-87.5%). The mean age at disease onset was 9.5 days (range 6.6-29 days). Most of the infants had low birth weight (median weight 1,395 g; range 1,112-2,788 g, calculated on the reported mean weights). The main risk factors associated with NEC were: low birth weight, low gestational age, low Apgar score, perinatal complications, hyaline membrane disease, and umbilical catheterisation. The bacteria involved often included Enterobacteriaceae, particularly Escherichia coli, Klebsiella pneumoniae and Enterobacter cloacae type 3305573. The causative role of Clostridia in NEC is controversial. With regard to viral agents, coronarovirus, rotavirus and enterovirus, such as echovirus type 22, were isolated during some of the epidemics. The recommended control measures for NEC epidemics are those used for epidemics of other orofaecally transmitted infections. CONCLUSION: Understanding the epidemiology of necrotising enterocolitis is fundamental if adequate preventive control measures are to be developed and applied.

Risk management of HBsAg or anti-HCV positive healthcare workers in hospital.

Recommendations are made for controlling the transmission of the hepatitis B and hepatitis C viruses from healthcare workers to patients. These recommendations were based both on the literature and on experts' opinions, obtained during a Consensus Conference. The quality of the published information and of the experts' opinions was classified into 6 levels, based on the source of the information. The recommendations can be summarised as follows: all healthcare workers must undergo hepatitis B virus vaccination and adopt the standard measures for infection control in hospitals; healthcare workers who directly perform invasive procedures must undergo serological testing and the evaluation of markers of viral infection. Those found to be positive for: 1) HBsAg and HBeAg, 2) HBsAg and hepatitis B virus DNA, or 3) anti-hepatitis C virus and hepatitis C virus RNA must abstain from directly performing invasive procedures; no other limitations in their activities are necessary. Infected healthcare workers are urged to inform their patients of their infectious status, although this is left to the discretion of the healthcare worker; whose privacy is guaranteed by law. If exposure to hepatitis B virus occurs, the healthcare worker must undergo prophylaxis with specific immunoglobulins, in addition to vaccination.

[Epidemiologic surveillance in intensive care: how to organize it?].

Surveillance of nosocomial infections is the single most effective tool for nosocomial infection prevention. There are two main targets: a) prompt identification of indicators and epidemic events, in order to immediately start adequate interventions; b) comparison of local "own" experience to the nosocomial infections which would be expected in a population with similar clinical features. The microbiological laboratory is a reliable and economical source of information: it allows identification of "dangerous" microorganisms, monitoring of antimicrobial resistances, identification of epidemics due to a single agent. Active surveillance is necessary in every unit, in order to identify those specific indicators of infection, which are able to detect preventable events and which can be useful for "homogeneous" comparisons among ICUs. Accuracy (sensitivity and specificity) of identification methods and of case definition is of uttermost importance. It is equally important to collect patient data and care plan data targeted to document differences in type of treated patient and in type of level of care. A recent national survey among Italian public hospitals revealed a poor diffusion of surveillance: out of 428 responder hospitals, surveillance of epidemics and of antimicrobial resistance was active in less than 10%, surveillance in the unit was active in 15%, surveillance of sentinel pathogens was active in 22%.

Effectiveness of infection control measures in controlling a nosocomial outbreak of multidrug-resistant tuberculosis among HIV patients in Italy.

SETTING: Between October 1992 and February 1994, 33 cases of multidrug-resistant tuberculosis (MDR-TB) were diagnosed among patients infected by the human immunodeficiency virus (HIV) and hospitalised in an HIV ward in Milan, Italy. This outbreak was part of a much larger outbreak, begun in another hospital and probably transferred through a patient. OBJECTIVE: To evaluate risk factors for transmission and the effectiveness of infection control measures. DESIGN: 1) Active follow-up of exposed patients, 2) cohort study among HIV-infected patients exposed to MDR-TB cases before and after the implementation of control measures, 3) screening of close contacts of MDR-TB cases, and 4) molecular typing by restriction fragment length polymorphism (RFLP) analysis. RESULTS: The risk of MDR-TB was higher in patients with lower CD4+ lymphocyte percentages and longer duration of exposure. No difference in the daily risk was observed for in-patients vs day-hospital patients or by room distance from an infectious case. Of the 90 patients exposed before the implementation of infection control measures (i.e., October 1992-June 1993) 26 (28.9%) developed MDR-TB, whereas none of the 44 patients exclusively exposed after implementation developed MDR-TB, despite the continuing presence of infectious MDR-TB cases in the ward. CONCLUSION: Simple control measures were effective in significantly reducing nosocomial transmission among patients.

Standardization of antituberculosis drug resistance surveillance in Europe. Recommendations of a World Health Organization (WHO) and International Union Against Tuberculosis and Lung Disease (IUATLD) Working Group.

Surveillance of antituberculosis drug resistance is an essential tool for evaluating the quality of tuberculosis control programmes. Consensus-based recommendations on uniform reporting of antituberculosis drug resistance surveillance data in Europe have been developed by a Working Group of the World Health Organization (WHO) and the International Union Against Tuberculosis and Lung Disease (IUATLD). Laboratories should use standardized methods for testing drug susceptibility with a quality assurance programme including national and international proficiency testing. The proportion of drug resistance, particularly resistance to isoniazid, rifampicin or both (multidrug resistance) among all definite, i.e. culture-positive, tuberculosis cases at the start of treatment is the major indicator of interest. It should be calculated separately among patients treated previously and among those who have never been treated with > or = 1 month of combined antituberculosis drugs. The Working Group recommends that, in countries in which resources allow, laboratories report drug susceptibility test results on all isolates of the Mycobacterium tuberculosis complex. Test results of the specimen at the start of treatment and clinical data from the notification should be linked using a suitable identifier. Results should be presented by calendar year and analysed by age, sex, place of birth, site of disease and sputum smear results. In countries in which a routine system cannot be organized, representative surveys or sentinel systems are possible alternatives. In some countries, the annual prevalence of multidrug-resistant tuberculosis may be estimated through a national laboratory reporting system.

Surveillance of anti-tuberculosis drug resistance: results of the 1998/1999 proficiency testing in Italy. SMIRA (Italian Multicentre Study on Antituberculosis Drug Resistance) Study Group.

OBJECTIVE: To determine the accuracy of drug-susceptibility testing (DST) for isoniazid, rifampicin, ethambutol and streptomycin in a provisional network of 22 regional laboratories in Italy. METHODS: Methods, definitions and reference Mycobacterium tuberculosis strains were derived from the WHO/IUATLD Global Project on Anti-tuberculosis Drug Resistance Surveillance. The laboratories were selected based on technical skills required by the project, the number of DST performed annually and geographic localisation. The results (sensitive/resistant strain) were compared with the gold standard (global project results). Sensitivity (ability to detect true resistance), specificity (ability to detect true susceptibility), positive predictive values for resistance and susceptibility, efficiency and reproducibility were calculated in two rounds. RESULTS: Eighteen of 22 laboratories completed the first round of proficiency testing for the four drugs. Sensitivity was 76.6%, specificity 97.2%, predictive value of a resistant test 89.8% and of a susceptible test 86.8%, efficiency 87.8% and reproducibility 92.8%. A second round was performed by all those laboratories that did not achieve > or = 90% agreement with the results of the Global Project. Overall, after the second round, all the parameters except specificity improved, exceeding 90%. CONCLUSIONS: A network of 15 regional laboratories that fulfil the quality criteria for determining the susceptibility of M. tuberculosis to the four primary antituberculosis drugs was established in Italy.

Nosocomial infections in HIV infected patients. Gruppo HIV e Infezioni Ospedaliere.

OBJECTIVES: To determine the incidence of nosocomial infections (NI) in HIV-infected patients and to analyse some of the associated risk factors. DESIGN AND SETTING: Multicentre prospective study on consecutive HIV-infected patients admitted to 19 Italian acute-care infectious disease wards. METHODS: All patients admitted during a 1-year period were followed-up for NI until their discharge. Univariate and multivariate analyses were performed for NI risk factors. RESULTS: As of June 1998 a total of 344 NI occurred in 4330 admissions, with at least one NI in 273 admissions (6.3%). The incidence rate of NI was 3.6 per 1000 patient days [95% confidence interval (CI), 3.2-4.1]. Overall distribution by site was 36.6% bloodstream infections (BSI), 30.5% urinary tract infections, 18.4% pneumonia, 5.2% skin/soft tissue infections, 2.0% surgical wound infections and 7.3% others. Fifty-five out of the 126 BSI were related to a central venous catheter (CVC); the rate of CVC-associated infections was eight infections per 1000 devices. At multivariate analysis, variables independently associated with NI included CD4 T-lymphocyte count < 200 x 10(6)/l [odds ratio (OR), 2.21; 95% CI, 1.35-3.62], Karnofsky Performance Status < 40 (OR, 1.89; 95% CI, 1.28-2.78), therapy with corticosteroids (OR, 1.78; 95% CI, 1.29-2.45), CVC (OR, 3.24; 95% CI, 2.41-4.35), urinary catheter (OR, 6.53; 95% CI, 4.81-8.86) and surgery (OR, 3.13; 95% CI, 1.90-5.15). CONCLUSIONS: Results suggest that NI occur commonly in HIV-infected patients. As the number of cases of HIV continues to increase, the number of HIV-infected patients requiring hospitalization may also increase. Clinicians need to be aware of the risk factors for NI and must consider these infections in the overall management of HIV-infected, hospitalized patients.

The threat of multidrug-resistant tuberculosis: results of 1 yr of surveillance in the Lombardy region of Italy.

A descriptive multicentre study based on laboratory data was carried out in patients with culture-confirmed tuberculosis (TB) who were cared for between September 1995 and August 1996 in 14 general hospitals with at least one human immunodeficiency virus (HIV) ward, a hospital specializing in TB or a large chest clinic, all in the Lombardy region of Italy. For each culture positive for Mycobacterium tuberculosis, the results of susceptibility tests to the five first-line anti-TB drugs were collected; other information collected included: the patient's name, the ward/service where the patient was staying and the characteristics of the culture (biological sample, date of arrival and type of mycobacterium isolated). Foreign-born persons were identified through their names; acquired immune deficiency syndrome (AIDS) patients were identified through record linkage with the National AIDS Registry. Given that only one-quarter of the laboratories performed pyrazinamide-susceptibility tests, resistance to this drug was not analysed. Of the isolates tested, 28.1% were resistant to at least one drug, i.e. single-drug-resistant (SDR) and 12.9% were multidrug-resistant (MDR). The frequency of SDR and MDR strains showed considerable variation by healthcare centre (range 0.0-94.3% and 0.0-37.1%, respectively). In three hospitals, the time of occurrence and the susceptibility pattern of the MDR-TB isolates indicated that clusters of the disease occurred. The frequency of both SDR and MDR strains was significantly higher among AIDS patients (48.8% and 23.6%, respectively) than among foreign-born persons (30.2% and 6.9%) or persons belonging to no known risk group (98.3% and 11.3%). The frequency of drug resistance observed in this study is much higher than that reported in other European surveys and is comparable only to that observed in New York, before the implementation of an effective control programme. Acquired immune deficiency syndrome patients are at very high risk of multidrug-resistant tuberculosis: effective containment and infection control practices should be rigorously implemented to prevent the occurrence of this alarming phenomenon.
