Is the Rate of Early mobilization in Hip fracture patients using Alfentanil Better than standard opioid analgesia (REHAB)? A protocol for a prospective cohort study

This study will help to build a wider protocol aiming to improve early mobilization after hip fracture surgery. The results of this study will provide pain scores and mobility status which will either support use of subcutaneous alfentanil as the standard analgesic modality prior to physiotherapy sessions, or highlight its limitations compared to the standard oral oxycodone. Secondary outcomes will also help to assess if early mobilization improves outcomes compared to delayed mobilization.
