Objective To analyze the competency needs of aged care workers in elderly care institutions, so as to providea reference for accurate construction of nursing staff training program. Methods Aged care worker job information were captured from online job boards with Web Scraper software,and the data were cleaned, then content analysis was used to code the information of job qualifications and job responsibilities with the package of NVivo 12 Plus. Results A total of 1 567 job information were collected,but 925 (695 were life care givers related, 230 were integrated medical and support services givers related) were qualified after data cleaning. Four root nodes (knowledge, skills, characteristics and abilities) were extracted by combing and encoding job information. For life care givers, 16 second-level nodes and 37 third-level nodes were extracted, the most needed knowledge and skills were basal living nursing and safety precautions,and the most necessary characteristics and abilities were love, patience, responsibility, hard work and communication and expression ability. For integrated medical and support services givers, 21 second-level nodes and 35 third-level nodes were concluded, the most needed knowledge and skills were disease related and basal living nursing knowledge and skills, and the most necessary characteristics and abilities were the same as those of life care givers. Conclusion The knowledge and skills closely related to the job tasks are most needed for the two types of primary elderly care workers, followed closely by personality characteristics and quality, such as hard working, communication and expression ability. The competency requirement of integrated medical and support services giversis higher than that of life caregivers, information literacy will become an essential quality for caregivers due to the development of e-health services.
