Design outcomes

Primary

Measure	Time frame
Success rate of standard planes (standardized ultrasound images to determine DDH) imaging for newborns and infants	—

Secondary

Measure	Time frame
1) E-learning: Knowledge and skills (anatomy of the hip joint, image reading, ultrasound examinations and procedures, and health guidance for prevention) 2) Practical skills training: Technical proficiency, success rate of imaging, time required for imaging, operation of ultrasound equipment (videos during operation of ultrasound devices during training) 3) Trial study: Time required for imaging, degree of agreement between the assessment by community nurses and the physician's diagnosis (inter-rater reliability), results of manual assessment and ultrasonography assessment.	—
