The Impact Of Methodological Changes In The Colorectal Cancer Early Detection Program in the Osijek-Baranja County

Kolorektalni karcinom jedan je od najčešćih zloćudnih tumora u Republici Hrvatskoj. Kod osoba starijih od 50 godina povišen je rizik za razvoj kolorektalnog karcinoma. Vlada Republike Hrvatske 2007. godine donijela je Nacionalni program ranog otkrivanja raka debelog crijeva. Ciljevi su istraživanja usporediti rezultate prvih dvaju ciklusa provedbe Nacionalnog programa u OBŽ-u te s obzirom na promjenu metodologije pozivanja osoba utvrditi postoji li razlika u odazivu, odnosno rezultatima probira. Iz baze podataka cilj je izračunati prvi i drugi odaziv te pokazati rezultate obaju ciklusa. Studija je retrospektivna. Ciljna su skupina osobe obuhvaćene Nacionalnim programom na području OBŽ-a. U prvom ciklusu Nacionalnog programa ranog otkrivanja raka debelog crijeva u Osječko-baranjskoj županiji pozvano je 105075 osoba, a poziv je primilo 96806 osoba. Pozivu se odazvalo 19940 osoba ili 20.6 %. U NPP-u testirano je njih 19600, odnosno 20.2 %. U drugom ciklusu Nacionalnog programa ranog otkrivanja raka debelog crijeva u Osječko-baranjskoj županiji pozvana je 103001 osoba, a poziv je primilo 94812 osoba. Pozivu se odazvalo 22647 osoba ili 23.9 %. U NPP-u testirano je njih 15907, odnosno 16,8 %. Znatno veći postotak osoba odazvao se na poziv u drugom ciklusu, ali je na okultno krvarenje testiran manji broj osoba. Nije postignut postavljeni cilj da se u okviru Programa testira 60 % pozvanih osoba.Colorectal cancer is one of the most commonly diagnosed malignant tumors in the Republic of Croatia. There is an increased risk of colorectal cancer among the population older than 50. In 2007, the Government of the Republic of Croatia developed a National Program for the early detection of the colorectal cancer. The goal of this research is to compare the results of the first two cycles of the National Program in Osijek – Baranja County and, considering the change in methodology of calling people to participate in the Program, to determine if there is a change in response rates based on the results of the screening. The study is retrospective. The targeted population consists of people covered by the National program in the Osijek – Baranja County. In the first cycle of the National program for the early detection of the colorectal cancer in Osijek – Baranja County, 105075 people have been called, and 96806 people have received a call. Out of all the people who received the call, 19940 people responded to it, i.e. 20.6% and 19600 people have been tested in the Program, i.e. 20.2%. In the second cycle of the National program for the early detection of the colorectal cancer in Osijek – Baranja County, 103001 people have been called, and 94812 people have received a call. Of the people who received it, 22647 people responded, i.e. 23.9% and 15907 people have been tested in the Program, i.e. 16.8%. A considerably larger number of people responded to the call in the second cycle, but less people were tested in the Program. The goal of the Program was to achieve a participation rate of 60%, but it was not reached. Key words
