ABSTRACT

Objective:To estimate the frequencies of medical X-ray diagnositic examinations and analyze their distribution in Huai′an City.Methods:Stratified random sampling was used to select 2 tertiary hospitals including 1 general hospital and 1 MCH hospital, 4 secondary hospitals, 20 primary and unclassified hospitals to investigate medical X-ray examination frequencies in the 26 hospitals in 2017.Results:The average number of X-ray diagnostic equipment were 13.5 pieces in tertiary hospitals, 7.3 in second-level hospitals and 1.6 in primary and ungraded hospitals. The fraction of imported equipment accounted for 85.2%, 69.0% and 9.4%, respectively. The higher the hospital level, the greater the proportion of equipment with five years of service history. The number of examinations in 2017 in the 26 hospitals were X-ray photography 350 221, fluoroscopy 71 597, CT 327 404, dental 23 820 and breast 12 849, respectively. The number of examinations per 1 000 population were estimated to be 444.22 by conventional X-ray and 236.40 by CT.Conclusions:The frequency of conventional X-ray examinations in the city is slightly lower than the average level in Jiangsu province in 2016 and the CT examination frequency is roughly same as in Jiangsu province.
