Monitoring of Patients With Inflammatory Bowel Diseases: the Experience of the Reference Center of the Emilia-Romagna

The study is observational with descriptive purposes, aimed at enhancing and deepening current knowledge and providing a foundation for future studies. Specifically, it seeks to identify predictive factors for aggressive disease progression, the development of frailty, the need for surgery and post-surgical outcomes, the development of neoplasia, the assessment of drug safety, and the quality of life in relation to medications or post-surgery.

The total duration of the study is expected to be 10 years. Partial analyses will be conducted during the study for data publication. The clinical data required by the protocol will be collected in a pseudonymized form by personnel designated by the Principal Investigator in an electronic Case Report Form (CRF). Analysis Methodology: Descriptive statistical analyses will be used to describe the characteristics of the enrolled patient sample. Continuous variables will be summarized using means, standard deviations, minimum and maximum values, and percentiles. Discrete or nominal variables will be reported as absolute frequencies and relative percentage frequencies. To study the predictive factors for disease progression, development of frailty, need for surgery, etc. (primary objectives), multivariate models (logistic regression analysis) will be used, and Odds Ratios with 95% confidence intervals (OR - CI 95%) will be calculated. The calculation of frequencies and the estimation of event incidences, such as drug resistance, development of comorbidities, extraintestinal manifestations, and other observed episodes/events (secondary objectives) will be accompanied by their respective 95% confidence intervals (CI 95%). Analyses may focus on subcohorts of patients with different demographic and clinical-diagnostic characteristics to evaluate their varying risk probabilities. Data will be processed using IBM SPSS statistical software (version 25.0).
