Equity in the recovery of elective and oncological surgery volumes after the COVID-19 lockdown: a multicentre cohort study in Italy.

BACKGROUND: The COVID-19 pandemic has had, and still has, a profound impact on national health systems, altering trajectories of care and exacerbating existing inequalities in health. Postponement of surgeries and cancellation of elective surgical procedures have been reported worldwide. In Italy, the lock-down measures following the COVID-19 pandemic caused cancellations of surgical procedures and important backlogs; little is known about potential social inequalities in the recovery process that occurred during the post-lockdown period. This study aims at evaluating whether all population social strata benefited equally from the surgical volumes' recovery in four large Italian regions. METHODS: This multicentre cohort study covers a population of approximately 11 million people. To assess if social inequalities exist in the recovery of eight indicators of elective and oncological surgery, we estimated Risk Ratios (RR) through Poisson models, comparing the incidence proportions of events recorded during COVID-19 (2020-21) with those in pre-pandemic years (2018-19) for each pandemic period and educational level. RESULTS: Compared to 2018-19, volumes of elective surgery showed a U-shape with the most significant drops during the second wave or the vaccination phase. The recovery was socially unequal. At the end of 2021, incidence proportions among highly educated people generally exceeded the expected ones; RRs were 1.31 (95%CI 1.21-1.42), 1.24 (95%CI 1.17-1.23), 1.17 (95%CI 1.08-1.26) for knee and hip replacement and prostatic surgery, respectively. Among low educated patients, RR remained always < 1. Oncological surgery indicators showed a similar social gradient. Whereas volumes were preserved among the highly educated, the low educated were still lagging behind at the end of 2021. CONCLUSIONS: Surgical procedures generally returned to pre-pandemic levels but the low educated experienced the slowest recovery. An equity-oriented appraisal of trends in healthcare provision should be included in pandemic preparedness plans, to ensure that social inequalities are promptly recognised and tackled.

Association of Mediterranean diet with survival after breast cancer diagnosis in women from nine European countries: results from the EPIC cohort study.

BACKGROUND: The Mediterranean diet has been associated with lower risk of breast cancer (BC) but evidence from prospective studies on the role of Mediterranean diet on BC survival remains sparse and conflicting. We aimed to investigate whether adherence to Mediterranean diet prior to diagnosis is associated with overall and BC-specific mortality. METHODS: A total of 13,270 incident breast cancer cases were identified from an initial sample of 318,686 women in 9 countries from the European Prospective Investigation into Cancer and Nutrition (EPIC) study. Adherence to Mediterranean diet was estimated through the adapted relative Mediterranean diet (arMED), a 16-point score that includes 8 key components of the Mediterranean diet and excludes alcohol. The degree of adherence to arMED was classified as low (score 0-5), medium (score 6-8), and high (score 9-16). Multivariable Cox proportional hazards models were used to analyze the association between the arMED score and overall mortality, and Fine-Gray competing risks models were applied for BC-specific mortality. RESULTS: After a mean follow-up of 8.6 years from diagnosis, 2340 women died, including 1475 from breast cancer. Among all BC survivors, low compared to medium adherence to arMED score was associated with a 13% higher risk of all-cause mortality (HR 1.13, 95%CI 1.01-1.26). High compared to medium adherence to arMED showed a non-statistically significant association (HR 0.94; 95% CI 0.84-1.05). With no statistically significant departures from linearity, on a continuous scale, a 3-unit increase in the arMED score was associated with an 8% reduced risk of overall mortality (HR3-unit 0.92, 95% CI: 0.87-0.97). This result sustained when restricted to postmenopausal women and was stronger among metastatic BC cases (HR3-unit 0.81, 95% CI: 0.72-0.91). CONCLUSIONS: Consuming a Mediterranean diet before BC diagnosis may improve long-term prognosis, particularly after menopause and in cases of metastatic breast cancer. Well-designed dietary interventions are needed to confirm these findings and define specific dietary recommendations.

Effectiveness of community hospital post-acute care on mortality, re-admission, institutionalization, and activation of a home care programme in Emilia-Romagna region, Italy.

BACKGROUND: In Italy, there is scant evidence on the impact of Community Hospitals (CHs) on clinical outcomes. AIMS: To assess the effectiveness of CHs versus long-term care hospital or inpatient rehabilitation facilities on mortality, re-admission, institutionalization, and activation of a home care programme in the Emilia-Romagna Region (ERR-Italy) after acute hospitalisation. METHODS: We implemented a cohort study drawing upon the ERR Administrative Healthcare Database System and including hospital episodes of ERR residents subject ≥ 65 years, discharged from a public or private hospital with a medical diagnosis to a CH or to usual care between 2017 and 2019. To control for confounding, we applied a propensity score matching. RESULTS: Patients transferred to CHs had a significantly lower risk of dying but an increased risk of being readmitted to community or acute hospital within 30/90 days from discharge. The hazard of institutionalisation within 30/90 days was significantly lower in the whole population of the CH exposed group but not among patients with cardiac or respiratory chronic diseases or diabetes. The activation of a home care program within 90 days was slightly higher for those who were transferred to a CH. DISCUSSION: The findings of our study show mixed effects on outcomes of patients transferred to CHs compared to those who followed the post-acute usual care and should be taken with cautious as could be affected by the so-called 'confounding by indication'. CONCLUSIONS: The study contributes to the intermediate care available evidence from a region with a well-established care provision through CHs.

Urban-rural differences in hypertension prevalence in low-income and middle-income countries, 1990-2020: A systematic review and meta-analysis.

BACKGROUND: The influence of urbanicity on hypertension prevalence remains poorly understood. We conducted a systematic review and meta-analysis to assess the difference in hypertension prevalence between urban and rural areas in low-income and middle-income countries (LMICs), where the most pronounced urbanisation is underway. METHODS AND FINDINGS: We searched PubMed, Web of Science, Scopus, and Embase, from 01/01/1990 to 10/03/2022. We included population-based studies with ≥400 participants 15 years and older, selected by using a valid sampling technique, from LMICs that reported the urban-rural difference in hypertension prevalence using similar blood pressure measurements. We excluded abstracts, reviews, non-English studies, and those with exclusively self-reported hypertension prevalence. Study selection, quality assessment, and data extraction were performed by 2 independent reviewers following a standardised protocol. Our primary outcome was the urban minus rural prevalence of hypertension. Hypertension was defined as systolic blood pressure ≥140 mm Hg and/or diastolic blood pressure as ≥90 mm Hg and could include use of antihypertensive medication, self-reported diagnosis, or both. We investigated heterogeneity using study-level and socioeconomic country-level indicators. We conducted meta-analysis and meta-regression using random-effects models. This systematic review and meta-analysis has been registered with PROSPERO (CRD42018091671). We included 299 surveys from 66 LMICs, including 19,770,946 participants (mean age 45.4 ± SD = 9 years, 53.0% females and 63.1% from rural areas). The pooled prevalence of hypertension was 30.5% (95% CI, 28.9, 32.0) in urban areas and 27.9% (95% CI, 26.3, 29.6) in rural areas, resulting in a pooled urban-rural difference of 2.45% (95% CI, 1.57, 3.33, I-square: 99.71%, tau-square: 0.00524, Pheterogeneity < 0.001). Hypertension prevalence increased over time and the rate of change was greater in rural compared to urban areas, resulting in a pooled urban-rural difference of 5.75% (95% CI, 4.02, 7.48) in the period 1990 to 2004 and 1.38% (95% CI, 0.40, 2.37) in the period 2005 to 2020, p < 0.001 for time period. We observed substantial heterogeneity in the urban-rural difference of hypertension, which was partially explained by urban-rural definition, probably high risk of bias in sampling, country income status, region, and socioeconomic indicators. The urban-rural difference was 5.67% (95% CI, 4.22, 7.13) in low, 2.74% (95% CI, 1.41, 4.07) in lower-middle and -1.22% (95% CI, -2.73, 0.28) in upper-middle-income countries in the period 1990 to 2020, p < 0.001 for country income. The urban-rural difference was highest for South Asia (7.50%, 95% CI, 5.73, 9.26), followed by sub-Saharan Africa (4.24%, 95% CI, 2.62, 5.86) and reversed for Europe and Central Asia (-6.04%, 95% CI, -9.06, -3.01), in the period 1990 to 2020, p < 0.001 for region. Finally, the urban-rural difference in hypertension prevalence decreased nonlinearly with improvements in Human Development Index and infant mortality rate. Limitations included lack of data available from all LMICs and variability in urban and rural definitions in the literature. CONCLUSIONS: The prevalence of hypertension in LMICs increased between 1990 and 2020 in both urban and rural areas, but with a stronger trend in rural areas. The urban minus rural hypertension difference decreased with time, and with country-level socioeconomic development. Focused action, particularly in rural areas, is needed to tackle the burden of hypertension in LMICs.

[Mortality and impact of COVID-19 by citizenship in seven Italian Regions from the beginning of the pandemic to mid-July 2021]. / Mortalità per COVID-19 nella popolazione immigrata in sette Regioni italiane da inizio pandemia a metà luglio 2021.

OBJECTIVES: to quantify the variability of COVID-19 mortality from the beginning of the pandemic to mid-July 2021, in relation to the immigrant status and by Region and period. DESIGN: observational incidence study. SETTING AND PARTICIPANTS: the study population consists of the residents at the beginning of 2020 in seven Regions (Piedmont, Lombardy, Veneto, Emilia-Romagna, Tuscany, Lazio, Sicily) aged <=74 years. MAIN OUTCOME MEASURES: absolute frequency of deaths occurred in subjects who tested positive for SARS-CoV-2, crude and standardized rates (standard: Italian population at the beginning of 2020), and mortality rates ratios (obtained using Poisson models), by immigrant status and stratified by gender, Region of residence, and period. The study period was divided into 5 subperiods: 22.02.2020-25.05.2020, 26.05.2020-02.10.2020, 03.10.2020-26.02.2021, 27.02.2021-16.07.2021. RESULTS: the study includes more than one half of the Italian population and most of the immigrants residing in the country, who are younger than Italians and experienced fewer COVID-19 deaths. Deaths among those who tested positive varied greatly between Regions and periods; standardized rates showed considerable increases over time among immigrants. In terms of rate ratios, there were excesses among immigrant males in the third period (MRR: 1.46; 95%CI 1.30-1.65) and in the fourth period (MRR: 1.55; 95%CI 1, 34-1.81). Among immigrant females, there is an indication of lower risk in the third period (MRR: 0.79; 95%CI 0.65-0.97) and of greater risk in the fourth period (MRR: 1. 46; 95%CI 1.21-1.77). Finally, the effect is modified by the Region of residence, both in the third and in the fourth period for males and only in the fourth period for females. CONCLUSIONS: the risk of premature mortality due to COVID-19 is linked to immigrant status and with an intensity that varies by gender, Region, and period. More accessible tools for prevention, diagnosis and early healthcare can support immigrant communities in managing the risk factors linked to the spread of infections and, in particular, counteract their evolution into more severe disease outcomes.

Educational inequalities in the prevalence and outcomes of diabetes in the Emilian Longitudinal Study.

BACKGROUND AND AIM: Studies carried out in Italy in the last decades reported an effect modification in the association between socioeconomic position and diabetes outcomes, and the disease integrated care approach has been suggested as an explanatory factor. Whether this is true in Emilia-Romagna region in recent years is unknown and the aim of this study is to describe the role of educational level both on diabetes prevalence and health outcomes among the adult population with and without diabetes enrolled in the Emilian Longitudinal Study. METHODS AND RESULTS: Inequalities in diabetes prevalence were evaluated through standardised estimates and prevalence ratios by educational level and inequalities in outcomes through standardised hospitalisation and mortality ratios and rate ratios by educational level. The lower the education the greater the diabetes prevalence; such differences were larger among women and younger age groups. Diabetes conferred a higher risk of hospitalisation and mortality; those outcomes also presented a social gradient with the less educated bearing the higher risk. However, educational differences were slightly stronger among the disease-free subjects, especially in the case of mortality. In both genders, inequalities tended to disappear with age. CONCLUSION: This study confirms that diabetes increases the risk of unfavourable outcomes, but does not increase social inequalities in outcomes as might be expected. Similarly to what has been previously shown, it is likely that the protective effect of diabetes on the negative health effects of the low social position is attributable to the disease integrated care approach.

Avoidable hospitalisation for diabetes mellitus among immigrants and natives: Results from the Italian Network for Longitudinal Metropolitan Studies.

BACKGROUND AND AIMS: Italy has experienced a relevant increase in migration inflow over the last 20 years. Although the Italian Health Service is widely accessible, immigrants can face many barriers that limit their use of health services. Diabetes mellitus (DM) has a different prevalence across ethnic groups, but studies focusing on DM care among immigrants in Europe are scarce. This study aimed to compare the rates of avoidable hospitalisation (AH) between native and immigrant adults in Italy. METHODS AND RESULTS: A multi-centre open cohort study including all 18- to 64-year-old residents in Turin, Venice, Reggio-Emilia, Modena, Bologna and Rome between 01/01/2001 and 31/12/2013-14 was conducted. Italian citizens were compared with immigrants from high migratory pressure countries who were further divided by their area of origin. We calculated age-, sex- and calendar year-adjusted rate ratios (RRs) and 95% confidence intervals (95% CIs) of AH for DM by citizenship using negative binomial regression models. The RRs were summarized using a random effects meta-analysis. The results showed higher AH rates among immigrant males (RR: 1.63, 95% CI: 1.16-2.23), whereas no significant difference was found for females (RR: 1.14, 95% CI: 0.65-1.99). Immigrants from Asia and Africa showed a higher risk than Italians, whereas those from Central-Eastern Europe and Central-Southern America did not show any increased risk. CONCLUSION: Adult male immigrants were at higher risk of experiencing AH for DM than Italians, with differences by area of origin, suggesting that they may experience lower access to and lower quality of primary care for DM. These services should be improved to reduce disparities.

[Urbanisation degree and mortality by education level in the Emilia-Romagna Longitudinal Study (Northern Italy)]. / Grado di urbanizzazione e mortalità per livello di istruzione nello Studio Longitudinale dell'Emilia-Romagna.

OBJECTIVES: to present the Longitudinal Study of Emilia-Romagna (SLER) and evaluate whether the effect of the education level on premature mortality is modified by the degree of urbanisation. DESIGN: closed cohort study. SETTING AND PARTICIPANTS: population aged >=30 years, resident in Emilia-Romagna Region (Northern Italy) and registered in the 2011 Italian Census, followed up until death, emigration, attainment of 75th year of age, or end of 2018. MAIN OUTCOME MEASURES: overall and cause-specific premature mortality (malignant tumours, lung and breast tumours, diseases of the circulatory system, respiratory system and digestive system, road accidents, death of despair, alcohol-related causes). RESULTS: the study population consisted of 2,579,936 individuals (15,508,972 person-years and 71,213 deaths). The population was equally distributed across the three degrees of urbanisation, but the prevalence of highly educated subjects was lower in the sparsely populated areas than in cities (12.9% vs 27.7%). The higher risk of mortality among the low educated was greatest, particularly among males, in the cities (MRR 1.68; 95%CI 1.62-1.75), lowest in the intermediate density areas (MRR 1.47; 95%CI 1.40-1.55), and not negligible among women. The interaction between education level and degree of urbanisation was significant for all-cause mortality, mortality from cardiovascular diseases, malignant tumours, especially lung cancer, road accidents (only among men). Among women, there were signs of an effect modification on mortality from diseases of respiratory and digestive systems. CONCLUSIONS: this first application of the SLER revealed that the mortality gradient by education level is greater in the cities, especially among men. These results deserve to be further explored through the analysis of other health outcomes and the investigation of the main drivers of the greater socioeconomic disadvantage observed in the cities.

Socioeconomic inequalities in overall and COVID-19 mortality during the first outbreak peak in Emilia-Romagna Region (Northern Italy).

OBJECTIVES: to provide a description of inequalities in overall and COVID-19 mortality by ecological socioeconomic measures (ESEMs) during the first outbreak peak (March and April 2020) in Emilia-Romagna Region. DESIGN: cross-sectional study based on the record linkage of the COVID-19 notification system, the regional population health register and the 2011 census data. SETTING AND PARTICIPANTS: residents in Emilia-Romagna who were grouped according to three ESEMs calculated at census block level: the index of deprivation, the household crowding, and the percentage of the foreign resident population. MAIN OUTCOME MEASURES: counts of all deaths and those directly attributable to COVID-19. The association between mortality and ESEMs was assessed through rate differences and mortality rate ratios, estimated through Poisson models. RESULTS: during the outbreak peak, the nine provinces of the Emilia-Romagna Region were unequally hit by the COVID-19 outbreak, with Piacenza recording the highest COVID-19 absolute death toll and Ferrara the lowest. The overall and COVID-19 mortality burden was unequal also in terms of ecological socioeconomic measures. Percentage differences in the age-standardised mortality rates between the least and the most disadvantaged census blocks were greater for COVID-19 mortality than for overall mortality, suggesting that the Coronavirus outbreak has had a stronger impact on the most socioeconomically deprived areas. Although clear gradients were not always present, people living in the most disadvantaged census blocks experienced the highest absolute and relative risk of dying. Rate differences were larger among men, but mortality rate ratios were not always greater among men than women, especially for the COVID-19 mortality. CONCLUSIONS: these descriptive yet informative results are relevant to document inequalities and inform regional public health policies and interventions in case of new COVID-19 surges.

Status inconsistency and mortality in the immigrant population in the Turin and the Emilian Longitudinal Studies.

OBJECTIVES: to compare the educational gradient in mortality between Italians and immigrants and to assess the hypothesis of status inconsistency in the immigrant population, evaluating the relationship between educational qualification and occupational class. DESIGN: multicentre longitudinal study. SETTING AND PARTICIPANTS: subjects aged 30-64 years, resident in Turin, Bologna, Modena, or Reggio Emilia who took part in the 2011 Census and followed up until 31.12.2018. MAIN OUTCOME MEASURES: all-cause mortality by educational qualification and occupational class was compared between Italians and immigrants from High Migratory Pressure countries; analyses were carried out using mortality rate ratios (MRR) and relative index of inequality (RII), applying Poisson models, adjusted for city, calendar period, age, and macroareas of origin, stratified by gender. RESULTS: occupational class among immigrants is evenly distributed across educational qualifications. Compared with Italians, immigrant men and women had a weaker and non-significant inverse educational gradient in mortality, which did not change substantially after the adjustment for occupational class. CONCLUSIONS: the results support the status inconsistency hypothesis, which may be partly responsible for the observed flattening of the educational gradients. The macroarea of origin appears to be a key determinant of mortality inequalities. Therefore, the use of educational qualification in exploring health inequalities among immigrants should be always complemented with other indicators of socioeconomic position and migratory history.

[Trends in educational inequalities in premature mortality between 2001 and 2016: results from the Emilian Longitudinal Study]. / Andamento delle disuguaglianze per livello di istruzione nella mortalità prematura tra il 2001 e il 2016 nello Studio longitudinale emiliano.

OBJECTIVES: to describe changes in relative and absolute inequalities in mortality by education level between 2001 and 2016 in the Emilian longitudinal study (SLEm) and to estimate the impact of these inequalities at population level. DESIGN: closed cohort study based on record-linkage between municipal population registries, Census archives of 2001 and 2011, and the mortality register. SETTING AND PARTICIPANTS: 2001- and 2011-Census respondents >=30 years old residing in Bologna, Modena, or Reggio Emilia followed up to the age of 75 years, death, emigration, or end of follow-up (December 2006 or December 2016). MAIN OUTCOME MEASURES: premature mortality for all causes and for 16 groups of causes known to be associated with socioeconomic position. In order to capture various aspects of the inequalities, the association with the education level is assessed through summary regression-based indexes (Relative and Slope Index of Inequality) and the Attributable Population Fraction. RESULTS: premature mortality declined across all educational level between 2001-2006 and 2011-2016; declines were greater among men than women. Among men, relative inequalities in mortality slightly increased (RII from 1.86 in 2001 to 2.13 in 2011), while absolute inequalities declined (SII from 382.3 to 360.6). Among women, both relative and absolute inequalities increased (RII from 1.23 to 1.65, SII from 73.7 to 137.4). Educational inequalities in lung cancer, respiratory and cerebrovascular diseases mortality decreased among men and increased among women. The proportion of the low educated shrank over time (men: from 40% to 36%; women: from 43% to 35%); nonetheless, the fraction of the deaths attributable to educational inequalities showed an upward tendency (from 18.5% to 21.9% in men and from 9.7% to 15.6% in women); the groups of causes that contribute most to this increase were malignant cancers, especially lung cancer, diseases of the circulatory and respiratory systems, and accidents. CONCLUSIONS: relative inequalities slightly increased in both genders, while absolute inequalities only in women. A reduction in the population impact could be achieved by tackling educational inequalities in mortality due to lung cancer, diseases of the circulatory and respiratory systems, and accidents.

An ecological study on health inequalities in the city of Bologna (Emilia-Romagna Region, Northern Italy): bridging knowledge and action.

BACKGROUND: since January 2017, a multidisciplinary research group, involving the Local Health Authority, the Municipality, and the University of Bologna, carried out a city-wide action-research project on health inequalities consisting of an ecological study over the years 2011-2015 based on indicators that are routinely available within health and social services. OBJECTIVES: to document existing geographical inequalities in health outcomes and use of healthcare services in the city of Bologna (Emilia-Romagna Region, Northern Italy), with the aim to suggest policy action to tackle them. DESIGN: the results of the first phase of the above-mentioned project were reported: five related to the social determinants of health (exposure) and five related to the social determinants of ill-health (outcomes). For each municipal statistical area, the distribution of the exposures as well as rates and Bayesian Relative Risks of the outcomes were plotted on the city map. To evaluate the association between social determinants and health outcomes, Spearman correlation coefficients were estimated. SETTING AND PARTICIPANTS: residents in the city of Bologna aged >=18 years in the period 2011-2015, grouped into 90 statistical areas. RESULTS: a North-South divide was apparent for most of the socioeconomic and ill-health indicators, with a high concentration of adverse outcomes in the North-Western part of the city. Adherence to cancer screening represented an exception, being greater in the areas with higher proportion of unfavourable health outcomes. An inverse association between education level and health outcomes was found. Low family income was weakly to moderately correlated with health outcomes. Proportion of residents in council houses and of the teenage foreign population showed a moderate to strong association with all outcomes, but mortality and screening adherence. CONCLUSIONS: an ecological analysis based on data that are routinely collected by local health and social institutions can be effective in revealing the geographical patterns of health inequalities. When accompanied by strategic choices aimed at bridging knowledge and action, this approach may facilitate the direct engagement of local actors towards health equity.

Surgical treatment and survival from colorectal cancer in Denmark, England, Norway, and Sweden: a population-based study.

BACKGROUND: Survival from colorectal cancer has been shown to be lower in Denmark and England than in comparable high-income countries. We used data from national colorectal cancer registries to assess whether differences in the proportion of patients receiving resectional surgery could contribute to international differences in colorectal cancer survival. METHODS: In this population-based study, we collected data from all patients aged 18-99 years diagnosed with primary, invasive, colorectal adenocarcinoma from Jan 1, 2010, to Dec 31, 2012, in Denmark, England, Norway, and Sweden, from national colorectal cancer registries. We estimated age-standardised net survival using multivariable modelling, and we compared the proportion of patients receiving resectional surgery by stage and age. We used logistic regression to predict the resectional surgery status patients would have had if they had been treated as in the best performing country, given their individual characteristics. FINDINGS: We extracted registry data for 139 457 adult patients with invasive colorectal adenocarcinoma: 12 958 patients in Denmark, 97 466 in England, 11 450 in Norway, and 17 583 in Sweden. 3-year colon cancer survival was lower in England (63·9%, 95% CI 63·5-64·3) and Denmark (65·7%, 64·7-66·8) than in Norway (69·5%, 68·4-70·5) and Sweden (72·1%, 71·2-73·0). Rectal cancer survival was lower in England (69·7%, 69·1-70·3) than in the other three countries (Denmark 72·5%, 71·1-74·0; Sweden 74·1%, 72·7-75·4; and Norway 75·0%, 73·1-76·8). We found no significant differences in survival for patients with stage I disease in any of the four countries. 3-year survival after stage II or III rectal cancer and stage IV colon cancer was consistently lower in England (stage II rectal cancer 86·4%, 95% CI 85·0-87·6; stage III rectal cancer 75·5%, 74·2-76·7; and stage IV colon cancer 20·5%, 19·9-21·1) than in Norway (94·1%, 91·5-96·0; 83·4%, 80·1-86·1; and 33·0%, 31·0-35·1) and Sweden (92·9%, 90·8-94·6; 80·6%, 78·2-82·7; and 23·7%, 22·0-25·3). 3-year survival after stage II rectal cancer and stage IV colon cancer was also lower in England than in Denmark (stage II rectal cancer 91·2%, 88·8-93·1; and stage IV colon cancer 23·5%, 21·9-25·1). The total proportion of patients treated with resectional surgery ranged from 47 803 (68·4%) of 69 867 patients in England to 9582 (81·3%) of 11 786 in Sweden for colon cancer, and from 16 544 (59·9%) of 27 599 in England to 4106 (70·8%) of 5797 in Sweden for rectal cancer. This range was widest for patients older than 75 years (colon cancer 19 078 [59·7%] of 31 946 patients in England to 4429 [80·9%] of 5474 in Sweden; rectal cancer 4663 [45·7%] of 10 195 in England to 1342 [61·9%] of 2169 in Sweden), and the proportion of patients treated with resectional surgery was consistently lowest in England. The age gradient of the decline in the proportion of patients treated with resectional surgery was steeper in England than in the other three countries in all stage categories. In the hypothetical scenario where all patients were treated as in Sweden, given their age, sex, and disease stage, the largest increase in resectional surgery would be for patients with stage III rectal cancer in England (increasing from 70·3% to 88·2%). INTERPRETATION: Survival from colon cancer and rectal cancer in England and colon cancer in Denmark was lower than in Norway and Sweden. Survival paralleled the relative provision of resectional surgery in these countries. Differences in patient selection for surgery, especially in patients older than 75 years or individuals with advanced disease, might partly explain these differences in international colorectal cancer survival.

[Immigrants' health and socioeconomic inequalities of overall population residing in Italy evaluated through the Italian network of Longitudinal Metropolitan Studies]. / Salute degli immigrati e disuguaglianze socioeconomiche nella popolazione residente in Italia valutate attraverso la rete degli Studi Longitudinali Metropolitani.

INTRODUCTION: Describing and monitoring socioeconomic inequalities in health are the prerequisite for planning equity policies. In Italy, some cities have integrated personal information from the municipal registries with Census data and with data from healthcare information systems to set up Longitudinal Metropolitan Studies (LMS). Under the coordination of the Italian National Institute for Health, Migration, and Poverty (NIHMP), six cities in the LMS network have contributed to the present monograph: Turin, Venice, Reggio Emilia, Modena, Bologna, and Rome. MORTALITY RESULTS. Significant socioeconomic differences by level of education were seen in all the participating centres. People who live alone or in single-parent households are more likely to die, as are those living in a substandard dwelling. Immigrants resident in the six cities included in the study showed lower all-cause mortality than Italians (males: MRR 0.83; 95%CI 0.78-0.90 - females: MRR 0.70; 95%CI 0.64-0.77). Sub-Saharan Africans experienced a significant higher mortality than Italians (males: MRR 1.33; 95%CI 1.12-1.59 - females: MMR 1.69; 95%CI 1.31-2.17). Immigrants had a neonatal and post-neonatal mortality risk about 1.5 times higher than Italians (neonatal: OR 1.71; 95%CI 1.22-2.39 - post-neonatal: OR 1.63; 95%CI 1.03-2.57). A difference between Italians and immigrants was also observed for mortality in children aged 1-4 years, though less marked (OR 1.24; 95%CI 0.73-2.11). Excesses concerned particularly immigrants from North Africa and from sub-Saharan Africa as well as those residing in Italy for >5 years. HOSPITALISATION RESULTS. Hospitalisation rates are lower for immigrants than for Italians, except when due to infectious diseases, blood disorders, and, among women, for reasons linked to pregnancy and childbirth. Avoidable hospitalisation rates of adults from low migratory pressure Countries are lower than or equal to those of Italians. On the contrary, adults from low migratory pressure Countries show higher avoidable hospitalisation rates compared to Italians in every cohort, with the exception of Rome (RR 0.81; 95%CI 0.78-0.85), with RR ranging from 1.08 (95%CI 0.96-1.22) in Venice to 1.64 (95%CI 1.47-1.83) in Modena. CONCLUSIONS: Maternal and child health is the most critical area of health for immigrant population. Considering the importance that the issue of health equity has taken on in the political agenda, the data presented in this volume are a great asset, particularly in light of the long recession and the social crisis that have impacted the Country.

Characteristics of patients with missing information on stage: a population-based study of patients diagnosed with colon, lung or breast cancer in England in 2013.

BACKGROUND: Stage is a key predictor of cancer survival. Complete cancer staging is vital for understanding outcomes at population level and monitoring the efficacy of early diagnosis initiatives. Cancer registries usually collect details of the disease extent but staging information may be missing because a stage was never assigned to a patient or because it was not included in cancer registration records. Missing stage information introduce methodological difficulties for analysis and interpretation of results. We describe the associations between missing stage and socio-demographic and clinical characteristics of patients diagnosed with colon, lung or breast cancer in England in 2013. We assess how these associations change when completeness is high, and administrative issues are assumed to be minimal. We estimate the amount of avoidable missing stage data if high levels of completeness reached by some Clinical Commissioning Groups (CCGs), were achieved nationally. METHODS: Individual cancer records were retrieved from the National Cancer Registration and linked to the Routes to Diagnosis and Hospital Episode Statistics datasets to obtain additional clinical information. We used multivariable beta binomial regression models to estimate the strength of the association between socio-demographic and clinical characteristics of patients and missing stage and to derive the amount of avoidable missing stage. RESULTS: Multivariable modelling showed that old age was associated with missing stage irrespective of the cancer site and independent of comorbidity score, short-term mortality and patient characteristics. This remained true for patients in the CCGs with high completeness. Applying the results from these CCGs to the whole cohort showed that approximately 70% of missing stage information was potentially avoidable. CONCLUSIONS: Missing stage was more frequent in older patients, including those residing in CCGs with high completeness. This disadvantage for older patients was not explained fully by the presence of comorbidity. A substantial gain in completeness could have been achieved if administrative practices were improved to the level of the highest performing areas. Reasons for missing stage information should be carefully assessed before any study, and potential distortions introduced by how missing stage is handled should be considered in order to draw the most correct inference from available statistics.

Observational pre-post study showed that a quality improvement project reduced paediatric antibiotic prescribing rates in primary care.

AIM: This study assessed the effectiveness of a quality improvement project that aimed to promote more considered antibiotic prescribing in paediatric primary care. METHOD: This was an observational pre-post study that used patient-level prescribing data from the Emilia-Romagna region of Italy to monitor indicators from 2005 to 2016. Multilevel interventions and activities were started in 2007 and these included developing guidelines and updates, disseminating evidence, audits and feedback, public information campaigns, engaging health managers and performance incentives. The primary outcomes were total antibiotic prescription rates for children aged 0-13 years and the rates for specific drugs. RESULTS: The intervention was associated with a significant reduction in the antibiotic prescribing rate, from 1307 per 1000 children in 2005 to 881 prescriptions in 2016 (p for trend <0.001), and a significant increase in the ratio of amoxicillin to amoxicillin-clavulanic acid, from 0.6 to 1.1 (p for trend = 0.001). Prescriptions of other second-choice antibiotics also declined significantly. In contrast, antibiotic prescribing rates remained high in the rest of Italy. CONCLUSION: The intervention was effective in promoting a more considered use of antibiotic in paediatric primary care in an Italian region. Further studies are needed to confirm its effectiveness in other settings.

Differences in mortality by immigrant status in Italy. Results of the Italian Network of Longitudinal Metropolitan Studies.

Despite a rapid increase in immigration from low-income countries, studies on immigrants' mortality in Italy are scarce. We aimed to describe differences in all and cause-specific mortality among immigrants and Italians residing in Turin and Reggio Emilia (Northern Italy), two cities participating in the Italian Network of Longitudinal Metropolitan Studies (IN-LiMeS). We used individual data from the municipal population registers linked to the cause of death registers. All people aged 1-64 years residing between 2001 and 2010 were enrolled (open cohort) and followed up until 2013. The mortality of citizens from high migratory pressure countries (as a whole, and for each macro-area group) was compared with that of Italians; differences were estimated by Poisson regression adjusted by age and calendar year mortality rate ratios (MRRs), and by age-standardized mortality ratios for the analysis of cause-specific mortality. Compared with Italians, immigrants had lower overall mortality (MRR for men: 0.82, 95 % CI: 0.75-0.90; for women: 0.71, 95 % CI: 0.63-0.81). Sub-Saharan Africans experienced a significant higher mortality than Italians (MRR for men 1.29, 95 % CI: 1.03-1.61; for women: 1.70, 95 % CI: 1.22-2.36). Higher mortality for immigrants compared to Italians was observed for infectious diseases, congenital anomalies, some site-specific tumours and homicide mortality. Our study showed heterogeneity in mortality across the macro-areas of origin, and in particular Sub-Saharan Africans seemed to be a vulnerable population. The extension to other cohorts of IN-LiMeS will allow the health status of immigrants and vulnerable groups to be studied and monitored in more depth.

[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.
