Full textThe CDC defines a chronic disease (CD) as a health condition which lasts at least one year and it requires continuous medical attention. Diabetes is one of the most diffused CD, and we refer to Type 2 Diabetes (T2D) when the body is not able to use insulin. Glucose Lowering Medications (GLMs) are used in T2D patients to control blood glucose, BMI, and blood pressure, to improve cardiovascular outcomes. Lots of RCTs have been conducted to evaluate GLMs. However, results obtained in RCTs have to be confirmed by real world data (RWD), which are routinely collected from different sources. In fact, RCTs have a very high internal validity but a low external validity. It is necessary to integrate knowledge from RCTs with Real World Evidence. However, when dealing with RWD, lots of problems arise due to the absence of randomization, confounding, and missing data. This thesis is focused on the application of advanced statistical approaches to analyze health outcomes and comorbidity patterns in patients with CDs from RWD. In the first contribution, Propensity Score (PS) methods have been applied to compare different GLMs, in terms of simultaneous reduction in HbA1c, body weight, and systolic blood pressure. Data were extracted from Dapagliflozin Real World evIdeNce in Type 2 Diabetes (DARWIN-T2D), a retrospective study conducted at diabetes specialist outpatient clinics in Italy. We observed that in routine ambulatory care, Dapagliflozin (a SGLT2i drug) can be as effective as GLP-1RA for the attainment of combined risk factor goals. However, we had to deal with lots of issues related to RWD: the absence of randomization, the high amount of missing data, and confounding. In the second contribution, I tried to overcome such issues applying different advanced statistical approaches, focusing on the case in which a high percentage of missing not at random (MNAR) data are present in the outcome. Covariate adjustment, PS adjustment, PS matching, inverse probability of treatment weighting, targeted maximum likelihood estimator (TMLE), were compared using DARWIN-T2D data and also in a simulation setting, done through Bayesian Networks (BNs) to resemble RWD characteristics. TMLE showed less biases and higher precision, even with MNAR outcome data. Then, in the third contribution, the aim was to evaluate generalizability of cardiovascular outcome trials (CVOTs) on GLP-1RA to the T2D RW population. The proportion of RW patients which constitute CVOT-like populations were assessed, using as target population DARWIN-T2D. We developed a novel approach, based on BNs, which was used to sample the greatest subsets of RW patients yielding true CVOT-like populations. A very small proportion of RW patients constitute true CVOT-like populations. In the fourth contribution, the aim was transferring CVOTs results to the RW setting (DARWIN-T2D). A post-stratification approach based on aggregated data of CVOTs and individual data of target population was used. Stratum-specific estimates available from CVOTs were extracted to calculate expected effect size for DARWIN-T2D by weighting the average of the stratum-specific treatment effects according to proportions of a given characteristic in the target population. The main finding was that cardiovascular protective actions of GLMs are transferrable to a different RW T2D population. In the fifth contribution, I worked on administrative databases of Piedmont, a Northern Italy region, to forecast urgent hospitalization in people aged more than 65 years. I applied the Bidirectional Encoder Representations from Transformers (BERT), which is a deep learning approach developed by Google. The aim was to deal with healthcare trajectories, defined as a sequence of medication purchases and hospitalization diagnoses, to forecast urgent hospitalizations within 3 months. Results suggested that BERT is able to embed administrative health records. This could be a tool to prevent adverse outcomes in a personalized way.

Full textA proliferated number of electronic healthcare databases has increased the role of observational studies as a tool to provide scientific evidence. Challenges in conducting observational studies based on Electronic Databases (ED) include concern about errors that can compromise the validity of the results. This thesis analyses methods and approaches to manage analytical challenges with regard to the study design and the statistical analysis of observational studies based on ED. Some of these techniques are performed in a study aimed to estimate the risk of a rare event, acute kidney injury (AKI) after contrast media (CM) administration. For that purpose, a cohort and a nested case-control study were performed using the discharged hospital database of Marche region. The cohort included 29925 subjects with a CM administration during 2008-2011. AKI occurred in 324 subjects; for 129 of them the time period after the CM administration was <7 days, considered therefore associated to AKI. The overall risk of AKI after CM administration was 0.43%. Subjects over 65 years old, suffering from a renal disease were at higher risk. In the nested case-control study all 324 cases were matched to 1258 controls. CM exposure and renal disease were significantly associated with a higher risk of AKI. A reduction of the exposure effect on AKI risk was found in those aged >65 years and with more than one CM administration, while an increased risk was found in subjects suffering from diseases different from renal and circulatory diseases. The study allowed us to estimate the risk of a rare event and the risk factors. Furthermore, it represents a concrete application of the current epidemiological methodology concerning problems related to the use of a potential data source but in the meantime should be cautiously applied.

Full textRheumatoid arthritis (RA) affects 0.5-1% of general population. The number of cardiovascular (CV) events in patients affected by RA is 2-3 times higher compared to subjects not affected by RA. Atherosclerosis is the initial sign of CV affection in RA patients, followed by cardiovascular and cerebrovascular events. Main CV risk factors in RA are: arterial hypertension (HA), dyslipidemia, diabetes mellitus (DM). Glucocorticoids induce hyperglycemia and insulin resistance. HA is correlated with the incidence of stroke, heart failure, and kidney diseases. Dyslipidemia is a complication of RA. CV events are: acute myocardial infarction (AMI), heart failure (HF), revascularization interventions, atrial fibrillation (AF) and strokes. AMI is the most common event. Another complication is cardiac insufficiency. Chronic inflammation plays an important role in the development of HF and AF. AF is the principal cardiac arrhythmia in the general population, with a higher incidence in RA subjects; it is the main reason for stroke, with stroke risk being higher in RA patients. Aim of the study: estimate the rate of incidence of CV events in RA patients, estimate the frequency of HA, DM, dyslipidemia, evaluate the correlation between CV risk factors and CV events in RA patients in comparison with the general population in Lombardy. The study design is: cohort, retrospective based on data extracted from health databases (AHD) from Lombardy Region between January 1st 2004 and December 31st 2013. Patients were selected applying the algorithm from the study RECord linkage on Rheumatic Diseases, thus identifying 70,061 RA patients. Subjects affected by CV events between January 1st 2004 and December 31st 2008 were not considered. 20,965 RA subjects and 245,933 non RA subjects were identified. 1,880 subjects of RA subjects presented at least one cardiovascular event. Our analysis confirms a significantly higher incidence for AMI, HF, and AF in RA subjects; the incidence of ischemic stroke shows no difference. Prevalence of HA and DM is higher in RA subjects in comparison with not-RA subjects (38.63% vs 34.29%, p value <0.001 / 9.03%>8.52%, p value 0.012). The prevalence of dyslipidemia is lower in RA subjects than not-RA subjects (15.11% vs 16.16%, p value <0.001). It is to be considered that cholesterol levels are reduced in high activity RA. RA is associated with an increased incidence rate (p<0.001) of AMI (49%), HF (51%), AF (26%). A similar increase of HF and AMI is observed in DM (61% and 53% respectively). No increase of stroke incidence was observed in RA patients. HA is the cardiovascular risk factor determining the highest increase of incidence rate of AF and HF, doubling the rate. In Lombard population, RA represents an independent risk factor for cardiovascular events.
