Prerequisites: Basic knowledge of SAS.
Target skills and knowledge: This course introduces the key concepts, models and statistical techniques for use in Epidemiology. In particular, at the end of the course the students will:
i) be familiar with the main types of epidemiological studies together with the corresponding measures of occurrence and effect.
ii) master the concepts of causality, confounding and effect modification together with the required analysis tools.
iii) be able to define a suitable sample to carry out an epidemiological study.
Examination methods: Computer lab test (SAS) and oral exam with discussion of a final report. The latter focuses on a real life problem and presents the findings from the statistical analysis of a suitable set of data. The topic must be agreed with the course instructors. The analysis may be carried out independently or by a two-person team.
Assessment criteria: The evaluations takes into account: the expertise and ability shown during the computer lab test (QUALIFICATION) and during the oral exam (weight 1/2), and the final report (weight 1/2). The final mark is the weighted average of the the marks achieved for the final report and during the oral exam.
Course unit contents: - Introduction to epidemiology: definitions and objectives.
- Causality and types of causal relations. Causal diagrams. Confounding and effect modification.
- Types of epidemiological studies: experimental studies (clinical trials, field trials, community intervention trials) and observational studies (cohort and case-control studies, cross-sectional and ecological studies, proportional mortality studies).
- Measures of disease occurrence and mortality: incidence, risk and prevalence. Relation between incidence and prevalence. Graphical representation (maps) of morbidity and mortality.
- Measures of exposure effects: absolute and relative. Relative risk, attributable risk, odds ratio. Relation between relative risk and odds ratio.
- Inference on incidence, prevalence, relative risk and odds ratio. Type 1 and type 2 error; power calculations.
- Methods to control for confounding: randomization (experimental studies), stratification, standardization, matching.
- Inference on the odds ratio in the presence of stratification (Mantel-Haenszel, logit, maximum likelihood) and matching (McNemar).
- Logistic regression for cohort studies and unmatched and 1:1 matched case-control studies.
- Further sources of bias: selection bias (self-selection, statistical bias, instrumental), misclassification (differential and non differential), representativity and generalization issues.
- Main data sources for public health studies and epidemiology and their information potential: surveys based on hospital discharge records, birth assistance certificates, death causes, information systems of the Italian Ministry for Public Health, disease registries. Definition and treatment of confidential data.
- Programming and evaluation of health care services: the Italian National Health Service, the National Health Plan, the Regional Health Plan and the local health plans. Basic assistance levels (LEA). Demand and supply of health care services.
- The evaluation of health cares services: indicators of resources, process and product. Benchmarking. Service effectiveness analysis. Composite indicators. Health care information systems.
Planned learning activities and teaching methods: This course rotates classroom lectures, hands-on exercises, SAS computer labs, reading groups and special topic talks by experts.
