International Classification of Functioning, Disability and Health Domains of 60 Physical Functioning Measurement Instruments Used During Adult Intensive Care Unit Stay: A Scoping Review

Abstract

Background: There has been a recent surge in the creation and adaptation of instruments to measure physical functioning (PF) in the intensive care unit (ICU). A key step to selecting the right measurement instrument is to understand the core constructs that it is measuring in terms of the International Classification of Functioning, Disability and Health (ICF) domains. Purpose: To map the ICF domains and subdomains included in the PF measurement instruments in adult patients during the ICU stay systematically. Data Sources: A systematic search was carried out in Cochrane CENTRAL, PubMed, CINAHL and LILACS as well as a hand search up to May 17, 2017. Study Selection: All types of research articles that used at least one PF measurement instrument in adult patients within the ICU were included. Data Extraction: Study design, year of publication, study population and the measurement instruments reported were recorded. A consensus of experts analyzed the ICF domains included in each instrument. Data Synthesis: One hundred and eighty-one articles containing 60 PF measurement instruments used during the ICU stay were found. Twenty-six ICF domains were identified, 40 instruments included Mobility and 13 included Muscle Function. Limitations: Studies not written in English or Spanish were excluded. Conclusions: There are numerous PF measurement instruments used in adult ICU patients. The most frequent ICF domain that is measured is Mobility. This study highlights the ICF domains contained in the instruments that can be used clinically, providing a complete database of instruments that could facilitate selection of the most appropriate measure based on the patients’ needs.
