Problems solved by technology

However, due to the existence of the shadowing effect, the signal detection of the data based on the disproportionate measurement theory cannot dig out the potential connection between the drug and the adverse reaction, so it is necessary to adopt a certain strategy to eliminate the shadowing effect
[0003] Regarding the elimination of the data masking effect in the detection of adverse drug reaction signals, domestic and foreign scholars have done some related research, mainly using methods ba

[0039] 1ADR data collection and preprocessing

[0040] 1.1 Raw ADR data collection and processing

[0041] A total of 1,823,144 ADR report data from January 1, 2010 to December 31, 2011 were obtained from the National Center for Adverse Drug Reaction Testing, of which 608,710 report records had multiple correspondences between multiple drugs and multiple adverse reactions, and split such data into pairs A single correspondence of one. After the split is completed, remove the abnormal data, and delete the records whose drug name or adverse reaction name is "unknown" in the data. In the final processing, 2,221,942 records were obtained, including 1,874,904 records of Western medicine data, accounting for 84.3%; 317,417 records of Chinese medicine data, accounting for 14.3%; 29,621 records of biological product data, accounting for 1.33%. In this example, western medicine data is selected as the experimental object.

Abstract

The invention discloses a layering strategy-based adverse drug reaction data shadowing effect eliminating method. According to the method, a data shadowing effect eliminating method is researched in adverse drug reaction signal detection on the basis of the adverse drug reaction report data of China, so that a layering strategy-based adverse drug reaction data shadowing effect eliminating model isdesigned; the data are layered on the whole according to the frequencies of the presence of drugs, adverse reactions and drug-adverse reaction pairs in the report data; and data detection is performed on the layered data through adopting an IC method. According to the invention, reports in which the frequencies of the presence of the drugs, adverse reactions and drug-adverse reaction pairs belongto the same order of magnitude are grouped into the same layer, so that the problem of data shadowing effects caused by excessively large difference of the frequencies of the presence of the drugs, adverse reactions and drug-adverse reaction pairs can be solved, and therefore, the data shadowing effects can be eliminated. With the method of the invention adopted, suspicious signals in the adversedrug reaction reports can be the accurately and reliably detected. The method has important reference significance in clinical care and drug supervision links.

Description

technical field [0001] The invention belongs to the field of signal detection, and in particular relates to a method for eliminating data masking effects in signal detection of adverse drug reactions in my country based on a layering strategy. Background technique [0002] At present, with the improvement of people's living standards, people pay more and more attention to drug safety issues while paying attention to medical drugs. The research on the detection of adverse drug reaction signals at home and abroad began in the 1950s with the "reaction stop" incident. my country's signal detection work mainly collects ADR data through the China Spontaneous Reporting Database and conducts data mining on the collected massive monitoring data. A widely used method in the field of signal detection is the disproportion measurement method, which is based on a four-table table and calculates the disequilibrium of the data distribution in the database. However, due to the existence of...
