Objective: To explore the application of the information system of infant hip joint screening in wide range screening of hip joint in children and to analyze the related data. Methods: The infant hip screening content, evaluation criteria, treatment guidance integrated into a form, relying on the Wuxi People’s Hospital Medical Association, to establish a set of developmental dysplasia of the hip (DDH) reporting system, all children within 6 weeks old serviced by hospital were examined by Graf ultrasonography for hip joint examination, upload data to the registration system, interventions for suspected children were conducted on the basis of systematic guidelines. The data obtained were statistically analyzed, and the effect of the information reporting system on the hip joint screening was evaluated. Results: From January 2015 to April 2017, 6 094 infants underwent Graf ultrasound screening of the hip. According to the guidance of the system, 44 cases were followed up, 36 cases were transferred to Wuxi Children’s Hospital, and 17 cases were diagnosed as DDH. Conclusion: The information reporting system can effectively monitor the development of the hip joint in infants, streamlining the layers of reporting process, and based on the guidance provided by the system can reduce human error, make the treatment more standardized and objective views. It also allows researchers monitor and collect the information of hip dysplasia more easily. The information reporting system of infant hip joint screening is practicable to screen the hip joint of infants and children. It is of guiding significance to the treatment and follow-up of the hip joint. However, the government medical insurance department should support it in the process of operation.
