Construction and validation of an instrument for physical therapy assessment and functional classification in the biopsychosocial model of the International Classification of Functioning, Disability and Health (ICF) for hospitalized HIV patients

Abstract

The human immunodeficiency virus (HIV) is responsible for the compromise of the immune system and a high number of hospitalizations. Considering the biopsychosocial (BPS) context of the individual, the International Classification of Functioning, Disability and Health (ICF) provides the maximum description of a health condition and the impact of interventions and service delivery for the physiotherapeutic process. The aim of this study was to build and validate a physical therapy assessment and functional classification instrument based on the ICF for hospitalized members of the HIV community. This is an observational, cross-sectional, and descriptive study based on the analysis of demand, elaboration, and improvement of the instrument and its validation with the consensus of a experts committee of physical therapists; they evaluated 58 items and the classification codes resulted in 0.858 overall Kappa value=strong agreement between assessments, all statistically significant (p-value<0.05). The final version of the instrument included 36 items, all with Kappa coefficient >0.80. The constructed instrument is valid for the evaluation and functional classification in the ICF model for hospitalized members of the HIV community, contributing to the physical therapy clinical practice in the hospital environment.
