{Abstract}: Hip fractures are common and significantly impact mobility and physical function. Measurement of patient progress post hip fracture in the acute hospital setting is important to monitor early recovery and outcomes. The objective of this systematic review was to assess the measurement properties (reliability, validity, responsiveness), interpretability, and clinical utility of instruments used to measure mobility and physical function in patients with hip fracture in the acute hospital setting.<BR>Three databases (MEDLINE, Embase, and CINAHL) were searched. Studies reporting direct clinician assessment instruments to measure mobility or physical function in patients with hip fracture were included. Data were extracted by 2 reviewers, and the quality of each study was determined using the COnsensus-based Standards for the selection of health Measurement INstruments risk of bias checklist.<BR>Sixty-eight studies were included with 19 measurement instruments identified. The most frequently used instruments were the Timed "Up & Go" Test (TUG) (19 studies), Barthel Index (BI) (18 studies), Cumulated Ambulation Score (CAS) (18 studies), and Functional Independence Measure (FIM) (14 studies). All 4 of these instruments demonstrated good predictive validity (clinical outcomes and mortality) and responsiveness over time (effect sizes 0.63-2.79). The BI and CAS also had good reliability (intraclass correlation coefficient [ICC] >0.70). Floor effects were demonstrated for the TUG, CAS, and FIM (16%-60% of patients). The TUG, CAS, and BI all had good clinical utility.<BR>Depending on the context (use by treating clinicians, research, benchmarking), 1 or a combination of the BI, CAS, and TUG provide robust measurement of mobility and physical function for patients with hip fracture in the acute hospital setting.<BR>This study identified 3 instruments suitable for measuring mobility and physical function in hospitalized patients following hip fracture. This provides clinicians with tools to measure patient progress and benchmark across sites to improve patient outcomes.
