Frailty

Frailty is a clinical syndrome that occurs in response to a complex interplay between various body systems, predisposing factors and environmental impacts resulting in heightened vulnerability to stressor events1. Frailty is gaining increasing recognition as an important treatable trait in the management of people with chronic lung disease due to its strong association with a range of adverse health outcomes. A detailed synthesis of evidence and knowledge regarding frailty in the context of chronic lung disease (the first of its kind) was recently published2 as well as an international workshop report focusing specifically on the role of pulmonary rehabilitation (PR) to manage this condition3.

As no single best method currently exists to assess frailty, we undertook a rapid review of the literature to describe the instruments commonly used in the context of PR. A systematic search of Medline (Ovid) was undertaken in May 2024 using a combination of terms related to frailty, rehabilitation and specific instrument titles (n = 110 papers). Additional handsearching was conducted to identify relevant information regarding instrument description, validity and reliability outside the PR context (n = 42). Only four instruments were found to be used across a range of different PR settings.

The following outcome measures are described:

  1. Clinical Frailty Scale
  2. Edmonton Frailty Scale
  3. Fried Frailty Scale
  4. Short Physical Performance Battery

Name of domains Cognition, balance & mobility, functional independence, social support, medication use, nutrition, mood, continence, burden of medical illness and quality of life[1].
Scaling of items Each item rated as 0, 1, 2 (6 items) or Yes, No (5 items)
Scoring Total score ranged from 0-17 by summation of ratings for items[1].
