In the cost of medical service projects in public hospitals, labor costs account for a large proportion of the cost of medical service projects, which can directly reflect the value of technical labor services of medical personnel and affect the long-term develop- ment vitality of hospitals. How can we improve the refinement level of hospital cost accounting through the accurate accounting of la- bor costs of medical service projects, optimize the allocation of human resources in the hospital, and make the technical elements of hospital talents fully effective? Drawing on the theoretical basis of the concept of “standardized workload”, it explores new ideas to strengthen the accurate accounting of labor costs for medical services, taking medical service inspection items as an example, and pro- viding accurate data to support the refinement of hospital staff management and high-quality hospital development.
