How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

e13074 Background: Colorectal cancer (CRC) remains one of the actual problems in oncology. In 2017, in the structure of oncopathology of the Republic of Kazakhstan (RK), CRC took the 3rd place in terms of incidence - 17.5, and in mortality - 8.2 per 100 thousand people. The population screening of CRC has been introduced in the Republic of Kazakhstan since 2011, among the population aged 50 to 70 years, with a survey interval every 2 years. Fecal immunochemical test (FIT) and total colonoscopy (TC) were introduced in 2013. Methods: For the period 2013 - 2018, 5133602 subjects were examined. The analysis of screening indicators was carried out: the number of positive results of FIT, completion rate of follow-up colonoscopy and CRC detection rate. The analyzed groups were divided into regions with: A - high (26 - 30.7 per 100 thousand people), B - medium (13.2-21.8), C - low (5.9 - 10.8) incidence. Results: The positive FIT for the study period was found on average, in 1.23% (62971) positive results in the Republic of Kazakhstan, in group A it was 1.50% (27675), in group B - 1.26% (17178), and in group C - 0.94% (18118). The number of TC: in group A - 76.1% (21067), in group B - 75.8% (13016), in group C was 66.7% (12080), in total - 46163 cases in the Republic of Kazakhstan, which is 73.3% of indications. During the period of study 2480 patients with colorectal cancer were identified: in group A - 0.07% (1236), in group B - 0.05% (638), in group C - 0.03% (606) people. Conclusions: For regions with different incidence rates is necessary to define performance indicators to improve the quality assurance in CRC screening.
