Insight into patients\u2019 resilience may help in getting more understanding of their predicted recovery and adjusting their treatment plan accordingly. This study aims to assess if fatigability, calculated with the Capacity to Perceived Vitality ratio (CPV), at baseline and its development over time, can provide insight into recovery and resilience at hospital discharge.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>In this prospective cohort study, patients were included from March 2022 to February 2024. Growth modelling was used to test whether there was a change in CPV over time during hospitalization and which covariables were associated with CPV.

At baseline, men had a factor 1.6 (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.01) higher CPV than women and patients with a pre-fracture KATZ-ADL 6 score of 0 had a factor 2.1 (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.003) higher CPV than patients with a pre-fracture KATZ-ADL 6 score of 2 or more.
