The aim of the present study was to identify all factors that might influence the short-term recovery of mobility in older adults' patients after hip surgery. A prospective cohort prognostic study was carried out. The study enrolled all consecutive patients aged 65 years or over admitted for hip fracture due to fragility. Patients were monitored from their admission into the emergency department of the hospital, until their discharge. The level of mobility was measured by the ILOA scale, administered during the 6th day of hospitalisation. The identified variables were divided into baseline patient variables, linked to the patient's characteristics, and, healthcare/hospital variables, linked to the program of care within post-surgery hospitalisation. The total number of patients enrolled and examined at discharge was 484. Six days after surgery, the level of mobility achieved by patients, as measured by ILOA Scale, was 42.4 (± 6.0). Increased age (B = 0.111; p = 0,042), pressure sore mattress with a motor used (B = 3.817; p < 0.0005), delay in achieving an upright position (B = 0.509; p < 0.0005), no recovery of walking (b = 2.339; p < 0.0005), prolonged use of diapers (B = 0.004; p < 0.0005) or catheter (B = 0.089; p < 0.0005), indication for no weight bearing (B = 2.023; p = 0.031), and temperature for fewer days (B = 0.040; p = 0.023) are factors able to affect negatively recovery of mobility in the initial post-operative period in patients surgically treated for hip fracture. Therapy and physiotherapy choices after surgery for hip fracture are significantly associated with early recovery of mobility of older adults' patients, regardless of their baseline conditions. Early removal of supporting devices promoting prolonged bed immobility, such as air mattress, catheter, and incontinence pad, together with achieving an early upright position, are elements to take into account when planning future trials to understand its efficacy in enabling better recovery of mobility.
