Insights
International experts identified typical and relevant categories from the International Classification of Functioning, Disability and Health (ICF) for various chronic conditions. This research is a key step toward developing ICF Core Sets for these conditions.
Area of Science:
- Rehabilitation Medicine
- Health Informatics
- Chronic Disease Management
Background:
- The International Classification of Functioning, Disability and Health (ICF) provides a standardized framework for describing health and functioning.
- Identifying condition-specific ICF categories is crucial for consistent data collection and clinical application.
- Previous research has not comprehensively identified typical ICF categories across a broad range of chronic conditions.
Purpose of the Study:
- To determine the most typical and relevant International Classification of Functioning, Disability and Health (ICF) categories for 12 distinct chronic conditions.
- To establish a consensus among international experts on ICF category relevance for specific patient populations.
- To lay the groundwork for the development of ICF Core Sets tailored to chronic diseases.
Main Methods:
- A global Delphi survey involving international experts was employed to gather data over three rounds.
- Expert responses were systematically linked to the International Classification of Functioning, Disability and Health (ICF) framework.
- Data analysis focused on identifying categories with a high degree of consensus among experts.
Main Results:
- Expert response rates varied from 21 to 43 participants per condition.
- For most conditions (excluding depression), at least 80% of experts agreed on typical and/or relevant ICF categories across all components.
- Distinct sets of relevant ICF categories were identified for each condition, alongside several common categories applicable to multiple conditions.
Conclusions:
- It is feasible to generate expert-validated lists of ICF categories for specific chronic conditions.
- These findings represent a significant advancement towards the creation of ICF Core Sets for managing chronic diseases.
- The identified ICF categories can enhance the standardization and comparability of functional status assessment in chronic care.
Objectives:
To identify the most typical and relevant categories of the International Classification of Functioning, Disability and Health (ICF) for patients with low back pain, osteoporosis, rheumatoid arthritis, osteoarthritis, chronic generalized pain, stroke, depression, obesity, chronic ischaemic heart disease, obstructive pulmonary disease, diabetes mellitus, and breast cancer.
Methods:
An international expert survey using the Delphi technique was conducted. Data were collected in 3 rounds. Answers were linked to the ICF and analysed for the degree of consensus.
Results:
Between 21 (osteoporosis, chronic ischaemic heart disease, and obstructive pulmonary disease) and 43 (stroke) experts responded in each of the conditions. In all conditions, with the exception of depression, there were categories in all ICF components that were considered typical and/or relevant by at least 80% of the responders. While all conditions had a distinct typical spectrum of relevant ICF categories, there were also some common relevant categories throughout the majority of conditions.
Conclusion:
Lists of ICF categories that are considered relevant and typical for specific conditions by international experts could be created. This is an important step towards identifying ICF Core Sets for chronic conditions.
