T/CI 071-2022 Cognitive impairment classification, rapid screening, and clinical diagnosis standards

Scope

Scope: This document provides the classification of cognitive frailty, as well as the technical content for rapid community screening and hospital clinical diagnosis. This document is applicable to community demographics, volunteers, clinical research, and clinical prevention and treatment. Main Technical Content: 3.13.2 Frailty Frailty refers to a clinical state characterized by a decline in the reserve function of multiple physiological systems, accompanied by an increase in vulnerability to stressors. Individuals exhibit an increased risk of adverse outcomes, including falls, hospitalization, declining independent living ability, and/or death. Frailty includes physical frailty, cognitive frailty, and psychosocial frailty. 3.33.4 Physical Frailty and Pre-Physical Frailty Physical frailty is a medical syndrome caused by multiple factors, characterized by reduced strength and endurance, declining physiological reserve, and an increased vulnerability to developing dependence or death. Pre-physical frailty is an early stage of physical frailty, typically involving fewer affected dimensions. Common screening tools for physical frailty include the Fried Frailty Screening Scale (Appendix B.1.3) and the FRAIL (Fried's Rapid Assessment of Illness in the Elderly) scale (Appendix B.1.1). The Fried Frailty Scale includes five main indicators: fatigue, weakness (reduced muscle strength), slowness (decreased walking speed), reduced physical activity, and unexplained weight loss. Currently, there is a Chinese version of the Fried Frailty Assessment Tool, which primarily consists of objective standards for the above indicators. Among these five indicators, the presence of 1-2 indicators indicates pre-physical frailty, and the presence of 3 or more indicates physical frailty. The FRAIL rapid screening questionnaire consists of five questions, including fatigue, endurance, aerobic exercise, disease, and weight loss; the responses are subjective and simple, with a short com
