Content comparison of long-term care instruments based on the international classification of functioning, disability and health (ICF)

BACKGROUND: Ageing poses a huge challenge to the Chinese social welfare system. However, a national long-term care (LTC) instrument has not been established yet. This study aimed to analyse and compare the content of six selected LTC instruments based on the linkage of the International Classification of Functioning, Disability and Health (ICF) to provide a content reference from a functioning perspective for the development of a Chinese national LTC instrument. METHODS: Two trained health professionals performed the linkage analysis according to the refined ICF linking rules. The main concepts included in the items of three international LTC instruments, namely Minimum Data Set 3.0 (MDS 3.0), Initial Assessment Instrument (IAI), and New Assessment Tool for Determining Dependency on Nursing Care (NBA), as well as three Chinese instruments, namely Disability Assessment of Long-Term Care (DA-LTC), Specification for Elderly Care Unified Need Assessment in Shanghai Version 2.0 (SEC-UNA 2.0), and pictorial-based Longshi Scale (LS), were selected and linked to the ICF categories. The six selected LTC instruments were analysed and compared at the levels of ICF components, chapters, and categories. RESULTS: The main concepts of 340 items of the six LTC instruments were linked to 112 different ICF categories. Within the ICF framework, the ‘Activities and Participation’ component was most frequently addressed in the LTC instruments, followed by ‘Body functions’, at 52% and 38%, respectively. At the chapter level, ‘b1 mental functions’, ‘d4 mobility’, and ‘d5 self-care’ were addressed by the majority of LTC instruments. CONCLUSION: The ICF provides a general reference for the analysis and comparison of different LTC instruments. The findings indicate that all LTC instruments focused on older adults’ physical needs; however, various important issues regarding their psychological and social participation needs were not addressed. Specific for China, the core elements of LTC instruments varied, and the ICF chapters ‘b1’, ‘d4’, and ‘d5’ are recommended to develop a national uniform one.
