ABSTRACT
BACKGROUND: Vaccine hesitancy is an emerging phenomenon in European countries and leads to decreasing trends in infant vaccine coverage. The aim of this study was to analyze the level of confidence and correct awareness about immunizations, which are crucial for the success of vaccination programmes. METHODS: As part of the NAVIDAD multicentre study, we examined vaccination confidence and complacency among a sample of 1820 pregnant women from 14 Italian cities. The questionnaire assessed the interviewee's knowledge, beliefs and misconceptions, as well as their socioeconomic status, information sources about vaccines and confidence in the Italian National Healthcare Service. RESULTS: Only 9% of women completely believed to the efficacy, necessity and safety of vaccinations. Almost 20% of them had misconceptions on most of the themes. There was a significant difference in the level of knowledge considering educational level: women with a high educational level have less probability of obtaining a low knowledge score (odds ratio (OR) 0.43 [95% confidence interval (CI) 0.34-0.54]). The level of knowledge was also influenced by the sources of information: women who received information from their general practitioner (GP) and from institutional websites had a significantly lower chance of having misconceptions (OR 0.74 [95% CI 0.58-0.96]; OR 0.59 [95% CI 0.46-0.74]). Finally, the results underlined the influence of trust in healthcare professional information on the likelihood of having misconceptions (OR 0.49 [95% CI 0.27-0.89]). CONCLUSIONS: The data suggest the efficacy of GPs and institutional websites as a source of information to contrast misconceptions and underline the importance of confidence in the healthcare system to increase complacency and confidence in vaccines.

BACKGROUND: The shift toward value-based care in the United States emphasizes the role of quality measures in payment models. Many diseases, such as prostate cancer, have a proliferation of quality measures, resulting in resource burden and physician burnout. This study aimed to identify and summarize proposed prostate cancer quality measures and describe their frequency and use in peer-reviewed literature. METHODS: The PubMed database was used to identify quality measures relevant to prostate cancer care, and included articles in English through April 2018. A gray literature search for other documents was also conducted. After the selection process of the pertinent articles, measure characteristics were abstracted, and uses were summarized for the 10 most frequently utilized measures in the literature. RESULTS: A total of 26 articles were identified for review. Of the 71 proposed prostate cancer quality measures, only 47 were used, and less than 10% of these were endorsed by the National Quality Forum. Process measures were most frequently reported (84.5%). Only 6 outcome measures (8.5%) were proposed-none of which were among the most frequently utilized. CONCLUSION: Although a high number of proposed prostate cancer quality measures are reported in the literature, few were assessed, and the majority of these were non-endorsed process measures. Process measures were most commonly assessed; outcome measures were rarely evaluated. In a step to close the quality chasm, a "top 5" core set of quality measures for prostate cancer care, including structure, process, and outcomes measures, is suggested. Future studies should consider this comprehensive set of quality measures.

The parallel epidemics of childhood asthma and obesity over the past few decades have spurred research into obesity as a risk factor for asthma. However, little is known regarding the role of asthma in obesity incidence. We examined whether early-onset asthma and related phenotypes are associated with the risk of developing obesity in childhood.This study includes 21â130 children born from 1990 to 2008 in Denmark, France, Germany, Greece, Italy, The Netherlands, Spain, Sweden and the UK. We followed non-obese children at 3-4â years of age for incident obesity up to 8â years of age. Physician-diagnosed asthma, wheezing and allergic rhinitis were assessed up to 3-4â years of age.Children with physician-diagnosed asthma had a higher risk for incident obesity than those without asthma (adjusted hazard ratio (aHR) 1.66, 95% CI 1.18-2.33). Children with active asthma (wheeze in the last 12â months and physician-diagnosed asthma) exhibited a higher risk for obesity (aHR 1.98, 95% CI 1.31-3.00) than those without wheeze and asthma. Persistent wheezing was associated with increased risk for incident obesity compared to never wheezers (aHR 1.51, 95% CI 1.08-2.09).Early-onset asthma and wheezing may contribute to an increased risk of developing obesity in later childhood.

BACKGROUND: Self-efficacy is an important mediator of the adaptation process after stroke. However, few studies have attempted to measure self-efficacy in a stroke population. The most recently developed scale is the Stroke Self-Efficacy Questionnaire that measures self-efficacy ratings in specific domains of functioning relevant for a stroke survivor. AIM: The aim of this study was to validate the Italian version of Stroke Self-efficacy Questionnaire in stroke survivors. DESIGN: Cross-sectional study. SETTING: Three Physical Medicine and Rehabilitation Units located in public hospitals. POPULATION: 149 adult patients recruited after their first stroke. METHODS: Patients were assessed using the Self-efficacy in stroke survivors questionnaire, the Modified Barthel Index, the Geriatric Depression Scale and the Short Form Health Survey. RESULTS: Patients (38.3% female, mean age 69.3 years) completed the Self-efficacy in stroke survivors questionnaire with the help of an interviewer. Using confirmatory factor analysis two factors were identified (activity and self-management). The factor score 'activity' was significantly associated with the Modified Barthel Index and with the physical component of the Short Form Health Survey, but uncorrelated with the mental component of the Short Form Health Survey and with the Geriatric Depression Scale, supporting the convergent/discriminant validity of the instrument. The 'self-management' factor was weakly associated with the Modified Barthel Index, the physical and mental components of the Short Form Health Survey and uncorrelated with the Geriatric Depression Scale, suggesting that it measures a different construct. When we categorized patients according to their walking status, we found that the walking group had significantly higher scores on the activity factor than the non-walking group, while no significant differences were found concerning the self-management factor. CONCLUSIONS: The findings supported the validity of the Italian version of the Stroke Self-efficacy questionnaire . It measures two dimensions of self-efficacy, activity and self-management, strongly related to independence and recovery after stroke and therefore it represents a useful tool to assess self-efficacy. CLINICAL REHABILITATION IMPACT: The Italian version of the Stroke Self-efficacy questionnaire is a valid and reliable measure of self-efficacy. Clinicians can use this instrument to target rehabilitation interventions according to patients' individual confidence in their functional and self-management capacity and in order to set realistic goals.

Addressing the opioid epidemic is a national priority. We analyzed national trends in inpatient and emergency department (ED) discharges for opioid abuse, dependence, and poisoning using Healthcare Cost and Utilization Project data. Inpatient and ED discharge rates increased overall across the study period, but a decline was observed for prescription opioid-related discharges beginning in 2010, while a sharp increase in heroin-related discharges began in 2008.

IMPORTANCE: There is increased interest in nonpharmacological treatments to reduce pain after total knee arthroplasty. Yet, little consensus supports the effectiveness of these interventions. OBJECTIVE: To systematically review and meta-analyze evidence of nonpharmacological interventions for postoperative pain management after total knee arthroplasty. DATA SOURCES: Database searches of MEDLINE (PubMed), EMBASE (OVID), Cochrane Central Register of Controlled Trials (CENTRAL), Cochrane Database of Systematic Reviews, Web of Science (ISI database), Physiotherapy Evidence (PEDRO) database, and ClinicalTrials.gov for the period between January 1946 and April 2016. STUDY SELECTION: Randomized clinical trials comparing nonpharmacological interventions with other interventions in combination with standard care were included. DATA EXTRACTION AND SYNTHESIS: Two reviewers independently extracted the data from selected articles using a standardized form and assessed the risk of bias. A random-effects model was used for the analyses. MAIN OUTCOMES AND MEASURES: Postoperative pain and consumption of opioids and analgesics. RESULTS: Of 5509 studies, 39 randomized clinical trials were included in the meta-analysis (2391 patients). The most commonly performed interventions included continuous passive motion, preoperative exercise, cryotherapy, electrotherapy, and acupuncture. Moderate-certainty evidence showed that electrotherapy reduced the use of opioids (mean difference, -3.50; 95% CI, -5.90 to -1.10 morphine equivalents in milligrams per kilogram per 48 hours; P = .004; I2 = 17%) and that acupuncture delayed opioid use (mean difference, 46.17; 95% CI, 20.84 to 71.50 minutes to the first patient-controlled analgesia; P < .001; I2 = 19%). There was low-certainty evidence that acupuncture improved pain (mean difference, -1.14; 95% CI, -1.90 to -0.38 on a visual analog scale at 2 days; P = .003; I2 = 0%). Very low-certainty evidence showed that cryotherapy was associated with a reduction in opioid consumption (mean difference, -0.13; 95% CI, -0.26 to -0.01 morphine equivalents in milligrams per kilogram per 48 hours; P = .03; I2 = 86%) and in pain improvement (mean difference, -0.51; 95% CI, -1.00 to -0.02 on the visual analog scale; P < .05; I2 = 62%). Low-certainty or very low-certainty evidence showed that continuous passive motion and preoperative exercise had no pain improvement and reduction in opioid consumption: for continuous passive motion, the mean differences were -0.05 (95% CI, -0.35 to 0.25) on the visual analog scale (P = .74; I2 = 52%) and 6.58 (95% CI, -6.33 to 19.49) opioid consumption at 1 and 2 weeks (P = .32, I2 = 87%), and for preoperative exercise, the mean difference was -0.14 (95% CI, -1.11 to 0.84) on the Western Ontario and McMaster Universities Arthritis Index Scale (P = .78, I2 = 65%). CONCLUSIONS AND RELEVANCE: In this meta-analysis, electrotherapy and acupuncture after total knee arthroplasty were associated with reduced and delayed opioid consumption.

BACKGROUND: Adaptive physical activity (APA) is a community-based exercise program for chronic stroke survivors that proved to be effective in improving physical functioning and psychological well-being in the short term. AIM: The aim of the present paper is to determine the effectiveness at twelve months of an intervention of APA combined with therapeutic patient education (TPE) in stroke survivors. DESIGN: This study is a non-randomized parallel group study comparing APA-TPE intervention with treatment as usual (TAU). SETTING: Patients were recruited after discharge from two Physical Medicine and Rehabilitation Units, 3 to 18 months after the stroke event. The APA-TPE intervention was conducted in local gymnasiums. POPULATION: The study population includes consecutive adult stroke survivors with mild to moderate hemiparesis who were able to walk 25 m independently and had no need of physical therapy. METHODS: The experimental group (N.=126) underwent 16 biweekly sessions of APA and 3 TPE sessions and controls (N.=103) underwent TAU. Twelve-month outcomes included the Modified Barthel Index, the Caregiver Strain Index, SF-12 health-related quality of life, medical complications and health services use. RESULTS: At twelve months, the ability to perform daily living activities, assessed using Modified Barthel Index, was decreased in the TAU group and improved in the APA-TPE group. The physical and mental components of quality of life were significantly improved in both groups. The risk of fractures (OR=0.09, 95% CI 0.01-0.79) and recourse to rehabilitation treatments (OR=0.24, 95% CI 0.08-0.77) were lower in the APA-TPE compared with the TAU group. No difference was found between groups concerning the caregiver burden. CONCLUSION: APA-TPE is an effective intervention to maintain and improve activities of daily living, reduce falls and recourse to rehabilitation treatments at twelve months. CLINICAL REHABILITATION IMPACT: Structured physical activity programs that can be performed also at home, when combined with therapeutic education focused on benefits of physical activity, will encourage stroke survivors to continue exercising. Therefore, it fulfills an essential requirement to the maintenance of lasting health benefits and the prevention of physical and psychological deterioration.

BACKGROUND: Children born preterm or with a small size for gestational age are at increased risk for childhood asthma. OBJECTIVE: We sought to assess the hypothesis that these associations are explained by reduced airway patency. METHODS: We used individual participant data of 24,938 children from 24 birth cohorts to examine and meta-analyze the associations of gestational age, size for gestational age, and infant weight gain with childhood lung function and asthma (age range, 3.9-19.1 years). Second, we explored whether these lung function outcomes mediated the associations of early growth characteristics with childhood asthma. RESULTS: Children born with a younger gestational age had a lower FEV1, FEV1/forced vital capacity (FVC) ratio, and forced expiratory volume after exhaling 75% of vital capacity (FEF75), whereas those born with a smaller size for gestational age at birth had a lower FEV1 but higher FEV1/FVC ratio (P < .05). Greater infant weight gain was associated with higher FEV1 but lower FEV1/FVC ratio and FEF75 in childhood (P < .05). All associations were present across the full range and independent of other early-life growth characteristics. Preterm birth, low birth weight, and greater infant weight gain were associated with an increased risk of childhood asthma (pooled odds ratio, 1.34 [95% CI, 1.15-1.57], 1.32 [95% CI, 1.07-1.62], and 1.27 [95% CI, 1.21-1.34], respectively). Mediation analyses suggested that FEV1, FEV1/FVC ratio, and FEF75 might explain 7% (95% CI, 2% to 10%) to 45% (95% CI, 15% to 81%) of the associations between early growth characteristics and asthma. CONCLUSIONS: Younger gestational age, smaller size for gestational age, and greater infant weight gain were across the full ranges associated with childhood lung function. These associations explain the risk of childhood asthma to a substantial extent.

BACKGROUND: Eczema, rhinitis, and asthma often coexist (comorbidity) in children, but the proportion of comorbidity not attributable to either chance or the role of IgE sensitisation is unknown. We assessed these factors in children aged 4-8 years. METHODS: In this prospective cohort study, we assessed children from 12 ongoing European birth cohort studies participating in MeDALL (Mechanisms of the Development of ALLergy). We recorded current eczema, rhinitis, and asthma from questionnaires and serum-specific IgE to six allergens. Comorbidity of eczema, rhinitis, and asthma was defined as coexistence of two or three diseases in the same child. We estimated relative and absolute excess comorbidity by comparing observed and expected occurrence of diseases at 4 years and 8 years. We did a longitudinal analysis using log-linear models of the relation between disease at age 4 years and comorbidity at age 8 years. FINDINGS: We assessed 16â147 children aged 4 years and 11â080 aged 8 years in cross-sectional analyses. The absolute excess of any comorbidity was 1·6% for children aged 4 years and 2·2% for children aged 8 years; 44% of the observed comorbidity at age 4 years and 50·0% at age 8 years was not a result of chance. Children with comorbidities at 4 years had an increased risk of having comorbidity at 8 years. The relative risk of any cormorbidity at age 8 years ranged from 36·2 (95% CI 26·8-48·8) for children with rhinitis and eczema at age 4 years to 63·5 (95% CI 51·7-78·1) for children with asthma, rhinitis, and eczema at age 4 years. We did longitudinal assessment of 10â107 children with data at both ages. Children with comorbidities at 4 years without IgE sensitisation had higher relative risks of comorbidity at 8 years than did children who were sensitised to IgE. For children without comorbidity at age 4 years, 38% of the comorbidity at age 8 years was attributable to the presence of IgE sensitisation at age 4 years. INTERPRETATION: Coexistence of eczema, rhinitis, and asthma in the same child is more common than expected by chance alone-both in the presence and absence of IgE sensitisation-suggesting that these diseases share causal mechanisms. Although IgE sensitisation is independently associated with excess comorbidity of eczema, rhinitis, and asthma, its presence accounted only for 38% of comorbidity, suggesting that IgE sensitisation can no longer be considered the dominant causal mechanism of comorbidity for these diseases.

BACKGROUND: Preterm birth, low birth weight, and infant catch-up growth seem associated with an increased risk of respiratory diseases in later life, but individual studies showed conflicting results. OBJECTIVES: We performed an individual participant data meta-analysis for 147,252 children of 31 birth cohort studies to determine the associations of birth and infant growth characteristics with the risks of preschool wheezing (1-4 years) and school-age asthma (5-10 years). METHODS: First, we performed an adjusted 1-stage random-effect meta-analysis to assess the combined associations of gestational age, birth weight, and infant weight gain with childhood asthma. Second, we performed an adjusted 2-stage random-effect meta-analysis to assess the associations of preterm birth (gestational age <37 weeks) and low birth weight (<2500 g) with childhood asthma outcomes. RESULTS: Younger gestational age at birth and higher infant weight gain were independently associated with higher risks of preschool wheezing and school-age asthma (P < .05). The inverse associations of birth weight with childhood asthma were explained by gestational age at birth. Compared with term-born children with normal infant weight gain, we observed the highest risks of school-age asthma in children born preterm with high infant weight gain (odds ratio [OR], 4.47; 95% CI, 2.58-7.76). Preterm birth was positively associated with an increased risk of preschool wheezing (pooled odds ratio [pOR], 1.34; 95% CI, 1.25-1.43) and school-age asthma (pOR, 1.40; 95% CI, 1.18-1.67) independent of birth weight. Weaker effect estimates were observed for the associations of low birth weight adjusted for gestational age at birth with preschool wheezing (pOR, 1.10; 95% CI, 1.00-1.21) and school-age asthma (pOR, 1.13; 95% CI, 1.01-1.27). CONCLUSION: Younger gestational age at birth and higher infant weight gain were associated with childhood asthma outcomes. The associations of lower birth weight with childhood asthma were largely explained by gestational age at birth.

BACKGROUND: Although population-based screening has the potential to reduce inequalities in breast cancer survival, evidence on this topic is controversial. The objective of this study was to evaluate whether the full implementation of a mammography screening programme in Emilia-Romagna in Italy had an impact on variations in breast cancer survival by educational level. METHODS: A cohort study was performed, including all women <70 years and residing in Emilia-Romagna who had infiltrating breast cancer registered in 1997-2000 (transitional screening period) or 2001-03 (consolidation screening period). Cancer cases were retrieved from the regional Breast Cancer Registry and followed up for 5 years. Educational level was determined from census data and allocated to cancer cases by individual record linkage. Age at diagnosis was classified into two groups (30-49, 50-69: screening target population). RESULTS: A total of 9639 cases were analyzed. In the 1997-2000 period, low-educated women had significantly lower survival compared with high-educated women, both in the younger and in the older age-groups. After the full implementation of the screening programme, these differences decreased in both age-groups, until disappearing completely among women in the age-group invited to screening. CONCLUSIONS: Our findings suggest that a fee-free population-based organized mammography screening programme with active invitation of the whole target population could be effective in reducing differences in survival in the population targeted by the screening.

BACKGROUND: The causal link between body mass index (BMI) or obesity and asthma in children is still being debated. Analyses of large longitudinal studies with a sufficient number of incident cases and in which the time-dependent processes of both excess weight and asthma development can be validly analyzed are lacking. OBJECTIVE: We sought to investigate whether the course of BMI predicts incident asthma in childhood. METHODS: Data from 12,050 subjects of 8 European birth cohorts on asthma and allergies were combined. BMI and doctor-diagnosed asthma were modeled during the first 6 years of life with latent growth mixture modeling and discrete time hazard models. Subpopulations of children were identified with similar standardized BMI trajectories according to age- and sex-specific "World Health Organization (WHO) child growth standards" and "WHO growth standards for school aged children and adolescents" for children up to age 5 years and older than 5 years, respectively (BMI-SDS). These types of growth profiles were analyzed as predictors for incident asthma. RESULTS: Children with a rapid BMI-SDS gain in the first 2 years of life had a higher risk for incident asthma up to age 6 years than children with a less pronounced weight gain slope in early childhood. The hazard ratio was 1.3 (95% CI, 1.1-1.5) after adjustment for birth weight, weight-for-length at birth, gestational age, sex, maternal smoking in pregnancy, breast-feeding, and family history of asthma or allergies. A rapid BMI gain at 2 to 6 years of age in addition to rapid gain in the first 2 years of life did not significantly enhance the risk of asthma. CONCLUSION: Rapid growth in BMI during the first 2 years of life increases the risk of asthma up to age 6 years.

BACKGROUND: Various studies indicate that inter-hospital comparisons have to take case mix into account and that risk adjustment procedures are necessary to control for potential predictors of cesarean delivery (CD). Different data sources have been used to retrieve information on potential predictors of CD. The aim of this study was to compare the discrimination capacity and fit of predictive models of CD created using different sources and to assess whether more complex models improve inter-hospital comparisons. METHODS: We created 4 predictive models of CD. One model included only variables from Hospital Discharge Records of the index hospitalization, one included also information from previous hospitalizations, one also clinical variables from birth certificates (BC) and one also socio-demographic variables. We compared the four models using the Receiver Operator Curve and the Akaike and Bayesian Information Criteria. RESULTS: Information from Birth Certificates improved the discrimination and model fit. Adding socio-demographic variables or past comorbidities did not improve the discrimination capacity or the model fit. Hospital-specific CD resulting from the models were highly correlated. CONCLUSIONS: Record linkage improves the performance of the models but does not affect inter-hospital comparisons.

BACKGROUND: Mortality amenable to health-care services ('amenable mortality') has been defined as "premature deaths that should not occur in the presence of timely and effective health care" and as "conditions for which effective clinical interventions exist." We analyzed the regional variability in health-care services using amenable mortality as a performance indicator. Convergent validity was examined against other indicators, such as health expenditure, GDP per capita, life expectancy at birth, disability-free life expectancy at age 15, number of diagnostic and laboratory tests per 1,000 inhabitants, and the prevalence of cancer and cardiovascular diseases. METHODS: Amenable mortality rate was calculated as the average annual number of deaths in the population aged 0-74 years per 100,000 inhabitants, and it was then stratified by gender and region. Data were drawn from national mortality statistics for the period 2006-08. RESULTS: During the study period (2006-08), the age-standardized death rate (SDR) amenable to health-care services in Italy was 62.6 per 100,000 inhabitants: 66.0 per 100,000 for males and 59.1 per 100,000 for females. Significant regional variations ranged from 54.1 per 100,000 inhabitants in Alto Adige to 76.3 per 100,000 in Campania. Regional variability in SDR was examined separately for male and females. The variability proved to be statistically significant for both males and females (males: Q-test = 638.5, p < 0.001; females: Q-test = 700.1, p < 0.001). However, among men, we found a clear-cut divide in SDR values between Central and Southern Italy; among women, this divide was less pronounced. Amenable mortality was negatively correlated with life expectancy at birth for both genders (male: r = -0.64, p = 0.002; female: r = -0.88, p <0.001) and with disability-free life expectancy at age 15 (male: r = -0.70, p <0.001; female: r = -0.67, p <0.001). Amenable mortality displayed a statistically significant negative relationship with GDP per capita, the quantity of diagnostic and laboratory tests per 1,000 inhabitants, and the prevalence of cancer. CONCLUSIONS: Amenable mortality shows a wide variation across Italian regions and an inverse relationship with life expectancy and GDP per capita, as expected.

BACKGROUND: Caesarean section (CS) rate is a quality of health care indicator frequently used at national and international level. The aim of this study was to assess whether adjustment for Robson's Ten Group Classification System (TGCS), and clinical and socio-demographic variables of the mother and the fetus is necessary for inter-hospital comparisons of CS rates. METHODS: The study population includes 64,423 deliveries in Emilia-Romagna between January 1, 2003 and December 31, 2004, classified according to theTGCS. Poisson regression was used to estimate crude and adjusted hospital relative risks of CS compared to a reference category. Analyses were carried out in the overall population and separately according to the Robson groups (groups I, II, III, IV and V-X combined). Adjusted relative risks (RR) of CS were estimated using two risk-adjustment models; the first (M1) including the TGCS group as the only adjustment factor; the second (M2) including in addition demographic and clinical confounders identified using a stepwise selection procedure. Percentage variations between crude and adjusted RRs by hospital were calculated to evaluate the confounding effect of covariates. RESULTS: The percentage variations from crude to adjusted RR proved to be similar in M1 and M2 model. However, stratified analyses by Robson's classification groups showed that residual confounding for clinical and demographic variables was present in groups I (nulliparous, single, cephalic, ≥37 weeks, spontaneous labour) and III (multiparous, excluding previous CS, single, cephalic, ≥37 weeks, spontaneous labour) and IV (multiparous, excluding previous CS, single, cephalic, ≥37 weeks, induced or CS before labour) and to a minor extent in groups II (nulliparous, single, cephalic, ≥37 weeks, induced or CS before labour) and IV (multiparous, excluding previous CS, single, cephalic, ≥37 weeks, induced or CS before labour). CONCLUSIONS: The TGCS classification is useful for inter-hospital comparison of CS section rates, but residual confounding is present in the TGCS strata.

BACKGROUND: Many pregnancy and birth cohort studies investigate the health effects of early-life environmental contaminant exposure. An overview of existing studies and their data is needed to improve collaboration, harmonization, and future project planning. OBJECTIVES: Our goal was to create a comprehensive overview of European birth cohorts with environmental exposure data. METHODS: Birth cohort studies were included if they a) collected data on at least one environmental exposure, b) started enrollment during pregnancy or at birth, c) included at least one follow-up point after birth, d) included at least 200 mother-child pairs, and e) were based in a European country. A questionnaire collected information on basic protocol details and exposure and health outcome assessments, including specific contaminants, methods and samples, timing, and number of subjects. A full inventory can be searched on www.birthcohortsenrieco.net. RESULTS: Questionnaires were completed by 37 cohort studies of > 350,000 mother-child pairs in 19 European countries. Only three cohorts did not participate. All cohorts collected biological specimens of children or parents. Many cohorts collected information on passive smoking (n = 36), maternal occupation (n = 33), outdoor air pollution (n = 27), and allergens/biological organisms (n = 27). Fewer cohorts (n = 12-19) collected information on water contamination, ionizing or nonionizing radiation exposures, noise, metals, persistent organic pollutants, or other pollutants. All cohorts have information on birth outcomes; nearly all on asthma, allergies, childhood growth and obesity; and 26 collected information on child neurodevelopment. CONCLUSION: Combining forces in this field will yield more efficient and conclusive studies and ultimately improve causal inference. This impressive resource of existing birth cohort data could form the basis for longer-term and worldwide coordination of research on environment and child health.

BACKGROUND: Cesarean section rates is often used as an indicator of quality of care in maternity hospitals. The assumption is that lower rates reflect in developed countries more appropriate clinical practice and general better performances. Hospitals are thus often ranked on the basis of caesarean section rates. The aim of this study is to assess whether the adjustment for clinical and sociodemographic variables of the mother and the fetus is necessary for inter-hospital comparisons of cesarean section (c-section) rates and to assess whether a risk adjustment model based on a limited number of variables could be identified and used. METHODS: Discharge abstracts of labouring women without prior cesarean were linked with abstracts of newborns discharged from 29 hospitals of the Emilia-Romagna Region (Italy) from 2003 to 2004. Adjusted ORs of cesarean by hospital were estimated by using two logistic regression models: 1) a full model including the potential confounders selected by a backward procedure; 2) a parsimonious model including only actual confounders identified by the "change-in-estimate" procedure. Hospital rankings, based on ORs were examined. RESULTS: 24 risk factors for c-section were included in the full model and 7 (marital status, maternal age, infant weight, fetopelvic disproportion, eclampsia or pre-eclampsia, placenta previa/abruptio placentae, malposition/malpresentation) in the parsimonious model. Hospital ranking using the adjusted ORs from both models was different from that obtained using the crude ORs. The correlation between the rankings of the two models was 0.92. The crude ORs were smaller than ORs adjusted by both models, with the parsimonious ones producing more precise estimates. CONCLUSION: Risk adjustment is necessary to compare hospital c-section rates, it shows differences in rankings and highlights inappropriateness of some hospitals. By adjusting for only actual confounders valid and more precise estimates could be obtained.
