- Cut-points to define slow walking speed have largely been derived from expert opinion.Study participants (13 589 men and 5043 women aged ≥65years) had walking speed (m/s) measured over 4-6 m (mean ± SD: 1.20 ± 0.27 m/s in men and 0.94 ± 0.24 m/s in women.) Mobility limitation was defined as any self-reported difficulty with walking approximately 1/4 mile (prevalence: 12.6% men, 26.4% women). Sex-stratified classification and regression tree (CART) models with 10-fold cross-validation identified walking speed cut-points that optimally discriminated those who reported mobility limitation from those who did not.Among 5043 women, CART analysis identified 2 cut-points, classifying 4144 (82.2%) with walking speed ≥0.75 m/s, which we labeled as "fast"; 478 (9.5%) as "intermediate" (walking speed ≥0.62 m/s but <0.75 m/s); and 421 (8.3%) as "slow" (walking speed <0.62 m/s). Among 13 589 men, CART analysis identified 3 cut-points, classifying 10 001 (73.6%) with walking speed ≥1.00 m/s ("very fast"); 2901 (21.3%) as "fast" (walking speed ≥0.74 m/s but <1.00 m/s); 497 (3.7%) as "intermediate" (walking speed ≥0.57 m/s but <0.74 m/s); and 190 (1.4%) as "slow" (walking speed <0.57 m/s). Prevalence of self-reported mobility limitation was lowest in the "fast" or "very fast" (11% for men and 19% for women) and highest in the "slow" (60.5% in men and 71.0% in women). Rounding the 2 slower cut-points to 0.60 m/s and 0.75 m/s reclassified very few participants.Cut-points in walking speed of approximately 0.60 m/s and 0.75 m/s discriminate those with self-reported mobility limitation from those without.

- Researchers face a challenge when evaluating the effectiveness of rehabilitation after a surgical procedure for hip fracture. Reported outcomes of rehabilitation will vary depending on the end point of the episode of care. Evaluation at an inappropriate end point might suggest a lack of effectiveness leading to the underuse of rehabilitation that could improve outcomes. The purpose of this article is to describe a conceptual framework for a continuum-care episode of rehabilitation after a surgical procedure for hip fracture. Definitions are proposed for the index event, end point, and service scope of the episode. Challenges in defining the episode of care and operationalizing the episode, and next steps for researchers are discussed. The episode described is intended to apply to all patients eligible for entry to rehabilitation after hip fracture and includes most functional recovery end points. This framework will provide a guide for rehabilitation researchers when designing and interpreting evaluations of the effectiveness of rehabilitation after hip fracture. Evaluation of all potential care episodes facilitates transparency in reporting of outcomes, enabling researchers to determine the true effectiveness of rehabilitation after a surgical procedure for hip fracture.
