Functional status versus quality of life: where does the evidence lead us?

The interchangeable use of functional status with quality of life has lead to various interpretations when discussing outcomes related to functional status. The literature revealed gaps in the measurement and blurred conceptualization of functional status. Given the prognostic importance of functional status measures, the results highlight the importance of developing a reliable and efficient means of obtaining a measure of functional status resulting in the advancement of nursing science. Having a clear and concise measure of functional status will enable clinicians to implement effect treatment plans that would lead to a faster recovery, higher level of functional status, and a greater well-being.
