clusters where the population suffers from worse health conditions is an important topic in social epidemiology, in order to identify health inequalities in cities and provide health policy interventions. This objective is particularly challenging because of the mechanism of self-selection of individuals into neighborhoods, which causes selection bias. The aim of this paper consists in the identification of neighborhood clusters where elderly people living in Turin, a city in north-western Italy, are exposed to an increased risk of hospitalized fractures. The study is based on administrative data and is a retrospective, observational cohort study. It is composed by a first phase, in which the individual confounding variables are balanced across neighborhoods in order to make them comparable, and a second phase in which the neighborhoods are aggregated into clusters characterized by significantly higher health risk. In the first phase we exploited a balancing technique based on partially ordered sets (poset), called Matching on poset based Average Rank for Multiple Treatments (MARMoT). On the balanced dataset, we used a spatial scan to identify the presence of clusters and we checked whether the risk of fracture is significantly higher in some contiguous areas. The combination of both MARMoT procedure and spatial scan makes it possible to highlight two clusters of neighborhoods in Turin where the risk of incurring hospitalized fractures for elderly people is significantly higher than the mean. These results could have important implications for the implementation of health policies.\r\n\r\n<\/p>\r\n\r\n<\/div>\r\n\r\n<pre id=\"bib20\" style=\"display:none;\">\r\n@article{silan2023identification,\r\n  author  = {Silan, Margherita and Belloni, Pietro and Boccuzzo, Giovanna},\r\n  title   = {Identification of Neighborhood Clusters on Data Balanced by a Poset-Based Approach},\r\n  journal = {Statistical Methods \\& Applications},\r\n  year    = {2023},\r\n  volume  = {32},\r\n  number  = {4},\r\n  pages   = {1295--1316},\r\n  doi     = {10.1007\/s10260-023-00695-0}\r\n}\r\n<\/pre>\r\n\r\n<\/details>\r\n\r\n<\/div>\r\n\r\n\r\n<div class=\"publication-list\">\r\n\r\n<details class=\"publication\">\r\n\r\n<summary>\r\n    \r\n    <div class=\"pub-type\"> Scientific article <\/div>\r\n\r\n<div class=\"pub-title\">\r\nConstruction of a Frailty Indicator with Partially Ordered Sets: A Multiple-Outcome Proposal Based on Administrative Healthcare Data\r\n<\/div>\r\n\r\n<div class=\"pub-authors\">\r\nMargherita Silan, Giada Signori, Elisa Ferracin, Elisabetta Listorti, Teresa Spadea, Giuseppe Costa, Giovanna Boccuzzo \r\n<\/div>\r\n\r\n<div class=\"pub-journal\">\r\nSocial Indicators Research \u2022 2022 \u2022 Vol.160, pp. 989\u20131017\r\n<\/div>\r\n\r\n<div class=\"pub-toolbar\">\r\n\r\n<div class=\"pub-links\">\r\n\r\n<a href=\"https:\/\/link.springer.com\/article\/10.1007\/s11205-020-02512-7#citeas\" target=\"_blank\">\r\n\ud83d\udd17 URL\r\n<\/a>\r\n\r\n<a href=\"https:\/\/link.springer.com\/content\/pdf\/10.1007\/s11205-020-02512-7.pdf\" target=\"_blank\">\r\n\ud83d\udcdd PDF\r\n<\/a>\r\n\r\n<a href=\"https:\/\/scholar.google.com\/scholar?hl=it&as_sdt=0%2C5&q=Construction+of+a+Frailty+Indicator+with+Partially+Ordered+Sets%3A+A+Multiple-Outcome+Proposal+Based+on+Administrative+Healthcare+Data&btnG=\" target=\"_blank\">\r\n\ud83c\udf93 Scholar\r\n<\/a>\r\n\r\n<a>\r\n\ud83d\udcc4 DOI: 10.1007\/s11205-020-02512-7\r\n<\/a>\r\n\r\n<\/div>\r\n\r\n<div class=\"right-tools\">\r\n\r\n<button class=\"bibtex-btn\" onclick=\"copyBibtex(event,'bib16')\">\r\n    \ud83d\udccb <span>Copy BibTeX<\/span>\r\n<\/button>\r\n\r\n<div class=\"arrow\">\r\n\u25bc\r\n<\/div>\r\n\r\n<\/div>\r\n\r\n<\/div>\r\n\r\n<\/summary>\r\n\r\n<div class=\"abstract\">\r\n\r\n<h4>Abstract<\/h4>\r\n\r\n<p>\r\n\r\nGiven the progressive aging of Italian and European populations, the number of cases with chronic diseases is steeply increasing. This calls for new strategies for health resource management and the implementation of prevention policies. Among chronic patients, frail subjects have special and wider care requirements, along with an increased risk of adverse health outcomes. Thus, their identification is an important step for the Italian National Program for Chronic Diseases. This study aims at constructing an indicator that measures the frailty level of individuals in the population aged over 65 y using administrative healthcare data-flows of the Piedmont region. Following the multidimensional nature of frailty, we adopted a multiple-outcome approach in our proposal. This was done by considering the capacity to predict six unfavorable outcomes: death, urgent unplanned hospitalization, access to the emergency room with red code, avoidable hospitalization, hip fracture, and disability. We identified a parsimonious set of seven explanatory variables that can simultaneously predict the six outcomes we considered. We then assembled them into a unique frailty indicator through the use of a partially ordered set (poset) theory. Our indicator performed well with respect to all the outcomes and was able to describe several individual characteristics that are not directly considered in the computation of the indicator. Thanks to its parsimony and to the use of administrative healthcare data, our indicator allows all the stakeholders involved in the healthcare process, such as Italian Local Health Units, general practitioners, and regional managers, to use it to target frail individuals with better comprehensive healthcare actions.\r\n\r\n<\/p>\r\n\r\n<\/div>\r\n\r\n<pre id=\"bib16\" style=\"display:none;\">\r\n@article{silan2022construction,\r\n  title={Construction of a frailty indicator with partially ordered sets: a multiple-outcome proposal based on administrative healthcare data},\r\n  author={Silan, Margherita and Signorin, Giada and Ferracin, Elisa and Listorti, Elisabetta and Spadea, Teresa and Costa, Giuseppe and Boccuzzo, Giovanna},\r\n  journal={Social Indicators Research},\r\n  volume={160},\r\n  number={2},\r\n  pages={989--1017},\r\n  year={2022},\r\n  publisher={Springer}\r\n}\r\n<\/pre>\r\n\r\n<\/details>\r\n\r\n<\/div>\r\n\r\n\r\n<div class=\"publication-list\">\r\n\r\n<details class=\"publication\">\r\n\r\n<summary>\r\n    \r\n    <div class=\"pub-type\"> Scientific article <\/div>\r\n\r\n<div class=\"pub-title\">\r\nMatching on poset\u2010based average rank for multiple treatments to compare many unbalanced groups\r\n<\/div>\r\n\r\n<div class=\"pub-authors\">\r\nMargherita Silan, Giovanna Boccuzzo, Bruno Arpino\r\n<\/div>\r\n\r\n<div class=\"pub-journal\">\r\nStatistics in Medicine \u2022 2021 \u2022 Vol.40(28), pp. 6443-6458\r\n<\/div>\r\n\r\n<div class=\"pub-toolbar\">\r\n\r\n<div class=\"pub-links\">\r\n\r\n<a href=\"https:\/\/onlinelibrary.wiley.com\/doi\/full\/10.1002\/sim.9192\" target=\"_blank\">\r\n\ud83d\udd17 URL\r\n<\/a>\r\n\r\n<a href=\"https:\/\/onlinelibrary.wiley.com\/doi\/epdf\/10.1002\/sim.9192\" target=\"_blank\">\r\n\ud83d\udcdd PDF\r\n<\/a>\r\n\r\n<a href=\"https:\/\/scholar.google.com\/scholar?hl=it&as_sdt=0%2C5&q=Matching+on+poset%E2%80%90based+average+rank+for+multiple+treatments+to+compare+many+unbalanced+groups&btnG=\" target=\"_blank\">\r\n\ud83c\udf93 Scholar\r\n<\/a>\r\n\r\n<a>\r\n\ud83d\udcc4 DOI: 10.1002\/sim.9192\r\n<\/a>\r\n\r\n<\/div>\r\n\r\n<div class=\"right-tools\">\r\n\r\n<button class=\"bibtex-btn\" onclick=\"copyBibtex(event,'bib19')\">\r\n    \ud83d\udccb <span>Copy BibTeX<\/span>\r\n<\/button>\r\n\r\n<div class=\"arrow\">\r\n\u25bc\r\n<\/div>\r\n\r\n<\/div>\r\n\r\n<\/div>\r\n\r\n<\/summary>\r\n\r\n<div class=\"abstract\">\r\n\r\n<h4>Abstract<\/h4>\r\n\r\n<p>\r\n\r\nIn this article, we propose an original matching procedure for multiple treatment frameworks based on partially ordered set theory (poset).

We engage in Monte Carlo simulations to evaluate the performance of inverse probability of treatment weighting (IPTW) with 10 treatments, estimating the propensity scores using Generalized Boosted Models. We assess the performance of IPTW under three different scenarios representing treatment allocations, and compare it with a simple parametric approach, i.e. logistic regression. IPTW's estimates are less biased, even though they exhibit a higher variance than those based on logistic regression. Moreover, we apply IPTW to the estimation of the neighbourhood effect on the probability of older people experiencing at least one fracture requiring hospitalization during the year 2002 by comparing 10 neighbourhoods in the city of Turin (Italy). Our paper demonstrates that IPTW can be successfully applied to the estimation of neighbourhood effects, and, more generally, to the estimation of causal effects in the presence of many treatments.\r\n<\/p>\r\n\r\n<\/div>\r\n\r\n<pre id=\"bib18\" style=\"display:none;\">\r\n@article{silan2021evaluating,\r\n  title={Evaluating inverse propensity score weighting in the presence of many treatments.

The Italian Chronic Disease Program\r\nlaunched by the Ministry of Health proposes the implementation of tools that stratify the\r\npopulation based on health and care needs and enhances the integration of existing admin-\r\nistrative health data flows. This work has its roots in the need to identify frail individuals\r\nconveyed by an Italian Local Health Unit (LHU) of the Veneto region and organize an\r\nefficient service of care and prevention. We propose an indicator of frailty, computed using\r\nthe poset approach, comprising only eight variables available in administrative health data\r\nat the LHU level. The proposed indicator associates a value of frailty between 0 and 1 to\r\nevery individual of the population aged 65 years and older, thereby allowing stratification\r\nof the population by the risk level. By validating and analyzing the frailty indicator, we\r\nshow that this approach provides an effective stratification of older people.\r\n\r\n<\/p>\r\n\r\n<\/div>\r\n\r\n<pre id=\"bib17\" style=\"display:none;\">\r\n@article{silan2019quantifying,\r\n  title={Quantifying Frailty in Older People at an Italian Local Health Unit},\r\n  author={Silan, Margherita and Caperna, Giulio and Boccuzzo, Giovanna},\r\n  journal={Social Indicators Research},\r\n  volume={146},\r\n  number={3},\r\n  pages={757--782},\r\n  year={2019},\r\n  publisher={JSTOR}\r\n}\r\n<\/pre>\r\n\r\n<\/details>\r\n\r\n<\/div>\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"<p>Publications on Partially Ordered Set (POSET) Theory Scientific article Identification of neighborhood clusters on data balanced by a poset-based approach Margherita Silan, Pietro Belloni, Giovanna<\/p>\n","protected":false},"author":2,"featured_media":0,"parent":53,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"","meta":{"footnotes":""},"class_list":["post-343","page","type-page","status-publish","hentry"],"_links":{"self":[{"href":"https:\/\/ideas.stat.unipd.it\/index.php\/wp-json\/wp\/v2\/pages\/343","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/ideas.stat.unipd.it\/index.php\/wp-json\/wp\/v2\/pages"}],"about":[{"href":"https:\/\/ideas.stat.unipd.it\/index.php\/wp-json\/wp\/v2\/types\/page"}],"author":[{"embeddable":true,"href":"https:\/\/ideas.stat.unipd.it\/index.php\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/ideas.stat.unipd.it\/index.php\/wp-json\/wp\/v2\/comments?post=343"}],"version-history":[{"count":6,"href":"https:\/\/ideas.stat.unipd.it\/index.php\/wp-json\/wp\/v2\/pages\/343\/revisions"}],"predecessor-version":[{"id":1400,"href":"https:\/\/ideas.stat.unipd.it\/index.php\/wp-json\/wp\/v2\/pages\/343\/revisions\/1400"}],"up":[{"embeddable":true,"href":"https:\/\/ideas.stat.unipd.it\/index.php\/wp-json\/wp\/v2\/pages\/53"}],"wp:attachment":[{"href":"https:\/\/ideas.stat.unipd.it\/index.php\/wp-json\/wp\/v2\/media?parent=343"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
