Abstract:
Objective To obtain the information on frequency of diagnostic medical X-ray examination and age distribution of examined individuals surveyed through samples from 12 hospitals in Inner Mongolia region to provide the basis for the optimization of medical exposure.Methods Stratified sampling method was used to select 12 hospitals in the region to survey the information of examined patients on sex,age and exposed location of patients undergoing medical X-ray examination in 2015 and 2016.Based on the information on number of inpatients,number of inpatients and total number of staff,the total frequency of medical X-ray examinations in the region for 2015 and 2016 was estimated by using multiple linear regression model.Results The survey showed that the total frequency of medical exposure was,in decreasing order,tertiary hospitals ＞ secondary hospitals ＞ primary hospitals,and meanwhile the general hospitals ＞ specialized hospitals.Values on frequency in general hospitals in 2015 and 2016 were 223 examinations per 1 000 population and 233 per 1 000 in conventional X-ray examination,96 per 1 000 and 125 per 1 000 in CT examination,1 per 1 000 and 2 per 1 000 in fluoroscopy,35 per 1 000 and 19 per 1 000 in dental radiology,1 per 1 000 and 2 per 1 000 in breast fluoroscopy in the region,respectively.Conclusions The frequency of radiological diagnosis and treatment in Inner Mongolia showed an rapid upward trend,but varied greatly dependent on the levels and types of medical institutions.Further surveys should be expanded with focuses on their comprehensiveness and relevancy.
