ICF linking rules: an update based on lessons learned.

OBJECTIVE: Outcome research seeks to understand the end results of health services. Researchers use a wide variety of outcome measures including technical, clinical and patient-oriented measures. The International Classification of Functioning, Disability and Health (ICF) as a common reference framework for functioning may contribute to improved outcome research. The objective of this paper is to provide an updated version of the linking rules published in 2002 and illustrate how these rules are applied to link technical and clinical measures, health-status measures and interventions to the ICF. RESULTS: Three specific linking rules have been established to link health-status measures to the ICF and one specific linking rule has been created to link technical and clinical measures and interventions. A total of 8 linking rules have been established for use with all different outcome measures and with interventions. CONCLUSION: The newly updated linking rules will allow researchers systematically to link and compare meaningful concepts contained in them. This should prove extremely useful in selecting the most appropriate outcome measures among a number of candidate measures for the applied interventions. Further possible applications are the operationalization of concrete ICF categories using specific measures or the creation of ICF category-based item bankings.

Content comparison of osteoporosis-targeted health status measures in relation to the International Classification of Functioning, Disability and Health (ICF).

The most frequently used instruments for health-related quality of life (HRQL) in patients with osteoporosis are the Quality of Life Questionnaire of the European Foundation for Osteoporosis (QUALEFFO-41) and the Osteoporosis Assessment Questionnaire (OPAQ 2.0 and OPAQ SV). Since HRQL- and International Classification of Functioning, Disability and Health (ICF)-based approaches have both strengths and weaknesses, it is expected that they will be used simultaneously in clinical practice and research. Therefore, we investigated the relationship between osteoporosis-targeted instruments and the ICF. All three selected instruments cover body functions, including pain in back and emotional functions. Sleep functions and energy are represented in the QUALEFFO-41 and OPAQ 2.0 but not in the OPAQ SV. Body structures and environmental factors are covered only by the OPAQ 2.0 and OPAQ SV. The ICF provides an excellent framework when comparing the content of osteoporosis-targeted HRQL instruments and may be useful when selecting health status instruments for clinical studies.

Development of ICF Core Sets for patients with chronic conditions.

OBJECTIVE: The objective of the ICF Core Sets project is the development of internationally agreed Brief ICF Core Sets and Comprehensive ICF Core Sets. METHODS: The methods to develop both ICF Core Sets, the Comprehensive ICF Core Set and the Brief ICF Core Set, involved a formal decision-making and consensus process integrating evidence gathered from preliminary studies and expert opinion. RESULTS: The results regarding the development of the ICF Core Sets for 12 health conditions (chronic widespread pain, low back pain, osteoarthritis, osteoporosis, rheumatoid arthritis, chronic ischemic heart disease, diabetes mellitus, obesity, obstructive pulmonary diseases, breast cancer, depression, and stroke) are presented in this supplement. CONCLUSION: Both, the Brief ICF Core Sets and the Comprehensive ICF Core Sets are preliminary and need to be tested in the coming years based on a standardized protocol in close cooperation with the ICF research branch of the WHO FIC CC (DIMDI) in Munich and the CAS team at WHO. The final goals are valid and globally agreed tools to be used in clinical practice, research and health statistics.

Identification of the most common patient problems in patients with chronic conditions using the ICF checklist.

OBJECTIVE: To identify the most common patient problems in patients with 12 different chronic conditions using the ICF checklist. METHODS: A multi-centre, cross-sectional study with convenient samples of patients who had received a clinical diagnosis of any of 12 different chronic conditions undergoing inpatient or outpatient rehabilitation. To describe the population, age, gender, and the SF-36 were recorded. Data for 917 patients from 33 rehabilitation centres were analysed. RESULTS: Most of the ICF-checklist categories were common to at least 1 condition. Pain was the sole category of 125 ICF-checklist categories that was common to all chronic conditions. Patients with low back pain, rheumatoid arthritis, and diabetes mellitus did not often experience the problems listed in the ICF-checklist. CONCLUSION: The main finding, that in most conditions categories from each component were common, underscores the need to address all components when assessing functioning and health in patients with chronic conditions.

ICF Core Sets for rheumatoid arthritis.

OBJECTIVE: To report on the results of the consensus process integrating evidence from preliminary studies to develop the first version of a Comprehensive ICF Core Set and a Brief ICF Core Set for rheumatoid arthritis. METHODS: A formal decision-making and consensus process integrating evidence gathered from preliminary studies was followed. Preliminary studies included a Delphi exercise, a systematic review, and an empirical data collection. After training in the ICF, and based on these preliminary studies, relevant ICF categories were identified in a formal consensus process by international experts from different backgrounds. RESULTS: The preliminary studies identified a set of 530 ICF categories at the second, third and fourth ICF levels with 203 categories on body functions, 76 on body structures, 188 on activities and participation, and 63 on environmental factors. Seventeen experts from 12 different countries attended the consensus conference on rheumatoid arthritis (7 physicians with at least a specialization in physical and rehabilitation medicine, 7 rheumatologists, one nurse, one occupational therapist, and one physical therapist). Altogether 96 categories (76 second-level and 20 third-, and fourth-level categories) were included in the Comprehensive ICF Core Set with 25 categories from the component body functions, 18 from body structures, 32 from activities and participation, and 21 from environmental factors. The Brief ICF Core Set included a total of 39 second-level categories, with 8 on body functions, 7 on body structures, 14 on activities and participation, and 10 on environmental factors. CONCLUSION: A formal consensus process integrating evidence and expert opinion based on the ICF framework and classification led to the definition of ICF Core Sets for rheumatoid arthritis. Both the Comprehensive ICF Core Set and the Brief ICF Core Set were defined.

ICF Core Set for patients with cardiopulmonary conditions in early post-acute rehabilitation facilities.

PURPOSE: The aim of this consensus process was to decide on a first version of the ICF Core Set for patients with cardiopulmonary conditions in early post-acute rehabilitation facilities. METHODS: The ICF Core Set development involved a formal decision-making and consensus process integrating evidence gathered from preliminary studies including focus groups of health professionals, a systematic review of the literature and empiric data collection from patients. RESULTS: Seventeen experts selected a total of 84 second-level categories. The largest number of categories was selected from the ICF component Body Functions (33 categories or 39% of all ICF Core Set categories). Four (5%) of the categories were selected from the component Body Structures, 23 (27%) from the component Activities and Participation, and 24 (29%) from the component Environmental Factors. CONCLUSIONS: The Post-acute ICF Core Set for patients with cardiopulmonary conditions is a clinical framework to comprehensively assess patients in early post-acute rehabilitation facilities, particularly in an interdisciplinary setting. This first ICF Core Set will be further tested through empiric studies in German-speaking countries and internationally.

ICF Core Sets development for the acute hospital and early post-acute rehabilitation facilities.

The goal of this paper is to report on the background and the methods used in the ICF Core Set development for patients in the acute hospital and early post-acute rehabilitation facilities. ICF Core Sets are sets of categories out of the International Classification of Functioning, Disability and Health (ICF) which can serve as minimal standards for the assessment, communication and reporting of functioning and health for clinical studies, clinical encounters and multi-professional comprehensive assessment and management. The ICF Core Sets were developed in a formal decision-making and consensus process, integrating evidence gathered from preliminary studies and expert opinion. The Acute ICF Core Sets for patients with neurological, musculoskeletal and cardiopulmonary conditions are intended for use by physicians, nurses, therapists and other health professionals working in the acute hospital on medical, surgical or other units not specialised in rehabilitation. The Post-acute ICF Core Sets for geriatric patients and patients with neurological, musculoskeletal or cardiopulmonary conditions are intended for use by physicians, nurses, therapists and other health professionals involved in early post-acute rehabilitation. The Acute and Post-acute ICF Core Sets are first versions and need to be tested and validated in the patient and professional perspective and in different countries, regions, health care and provider settings.
