With the rapid growth of the elderly population in China, the aging of the whole society has gradually deepened. By the end of 2021, the number of elderly people aged 60 and above in China reached 267 million, accounting for 18.9% of the total population. Recently, the State Administration of Market Supervision and Administration issued the national standard of "Criteria for the Assessment of the Ability of the Elderly". According to this standard, the living ability of the elderly can be scientifically assessed, and the corresponding levels can be divided, and then targeted care services can be provided. The ability evaluation of the elderly is the analysis and evaluation of the elderly's individual self-care ability, basic motor ability, mental state, perception and social participation by professionals according to relevant standards. "Generally speaking, the ability assessment of the elderly is somewhat similar to physical examination. The main content of physical examination is the health or disease status of the elderly. The main content of the ability assessment of the elderly is the ability of the elderly to live independently. These abilities include the ability of the elderly to take care of themselves, such as dressing, eating and bathing, walking up and down stairs and other basic sports abilities, mental state, perception and social participation." Li Banghua, deputy director of the Department of Elderly Care Services of the Ministry of Civil Affairs, said. How to accurately evaluate the living ability of the elderly? Guo Huanxin, the first-level inspector of the Standards and Technology Management Department of the General Administration of Market Supervision, introduced that the national standard "Evaluation Specifications for the Ability of the Elderly" issued and implemented this time is divided into six parts, mainly including "evaluation indicators and scores", "organization and implementation", "evaluation results", and three normative appendices: "Basic Information Sheet for the Evaluation of the Ability of the Elderly", "Evaluation Form for the Ability of the Elderly" and "Evaluation Report for the Ability of the Elderly". The main evaluation indicators in the standard include primary indicators and secondary indicators. Among them, the first-level indicators include self-care ability, basic motor ability, mental state, perception and social participation; The secondary indicators include 26 aspects, such as eating, wearing and taking off clothes, walking on the flat ground, going up and down stairs, memory, understanding ability, vision, hearing, and social interaction ability. The higher the score, the better the ability level. The ability of the elderly is divided into five levels according to the standard: intact ability, slightly impaired ability (slight disability), moderately impaired ability (moderate disability), severely impaired ability (severe disability), and completely disabled ability (complete disability). Compared with the 2013 version of the industry standard, "total disability" is added. "The release and implementation of the National Standards for the Evaluation of the Capacity of the Elderly will provide the basic basis for the scientific classification of the capacity of the elderly, the promotion of the construction of the basic old-age service system, the optimization of the supply of old-age services, and the standardization of the operation of old-age service institutions," said Guo Huanxin. Li Banghua said that the ability assessment of the elderly will play an important role in elderly care services. For the elderly and their families, the elderly participate in the assessment according to their needs, which is helpful to understand their own ability, arrange their later life more reasonably, and select appropriate professional services or apply for relevant security policies more targeted. The elderly and their families can also take timely measures to prevent aging, improve physical functions and give more targeted care to the elderly according to their ability. For elderly care service institutions, they can more accurately understand the service needs of each elderly person according to the evaluation results, and formulate the
