Lingua di insegnamento | Italiano |
Contenuti | Modulo integrato Metodologia Epidemiologica (Statistica Medica, Epidemiologia e Bioetica) |
Testi di riferimento | Epidemiologia, biostatistica e medicina preventive James Jekel,David Katz,Joann Elmore |
Obiettivi formativi | Utilizzare gli strumenti epidemiologici e statistici appropriati per ridurre l'area dell'incertezza nella rilevazione e nella interpretazione dei dati clinici per valutare le decisioni diagnostiche, prognostiche e terapeutiche |
Prerequisiti | Negli anni precedenti lo studente deve aver acquisito una buona metodologia di studio e un'adeguata capacità di autovalutazione. |
Metodologie didattiche | Lezioni frontali articolate nei seguenti moduli didattivi : Statistica Medica 50 ore, Epidemiologia 25 ore, Bioetica 25 ore con frequenza obbligatoria di almeno il 75% delle lezioni |
Metodi di valutazione | Prova scritta a risposta multipla finalizzata alla valutazione della capacità di interpretare i metodi statistici utilizzati per la valutazione della letteratura scientifica : Le domande del compito scritto hanno un punteggio decrescente in relazione al grado di difficoltà . Il punteggio totale della prova scritta è la somma dei punteggi ottenuta dalle singole materie del corso integrato. con un massimo di 31. Durante la prova non è consentito consultare materiale didattico o materiale informatico. Dopo il superamento della prova scritta con un punteggio minimo di 18/30, lo studente è ammesso a sostenere una prova orale facoltativa con I tre docenti del corso integrato. Il voto finale rappresenta la media dei voti dati da ciascun Docente. L’esame è atto a valutare la conoscenza degli argomenti del programma ed anche lo spirito critico dello studente sviluppato a seguito del corso. |
Altre informazioni | Il Corso viene svolto al primo semestre del terzo anno del Corso di Laurea. |

Course objectives | To use epidemiological and bio-statistical tools for a better understanding of biomedical information and for improving medical decision making |
Prerequisites | In previous years the student must have acquired a good study methodology and adequate capacity for self-assessment |
Teaching methods | Teaching techniques: Lectures supported by presentation of slides in Power Point.Medical statistics 50 hours, Epidemiology 25 hours and Bioethics 25 hours |
Evaluation methods | Multiple choice written exam aimed at evaluating the ability to interpret the statistical methods used for the evaluation of the scientific literature: The questions of the written task have a decreasing score in relation to the degree of difficulty. The total score of the written test is the sum of the scores obtained from the individual subjects of the integrated course. with a maximum of 31. |
