Introduction:

The incidence of hip fracture increases with age. The dependency generated by these traumas is associated with higher morbidity and mortality; it also reduces the quality of life, it increases the risk of institutionalization, and the consumption of health and social resources.

Objectives:

To assess the results of rehabilitation treatment after hip fracture surgery in a medium-stay unit and to identify the variables associated with functional, efficiency and effectiveness gain.

Methods:

A prospective observational study was conducted in 120 patients with secondary functional impairment after hip fracture surgery. They were selected through simple random sampling during 2022. The variables analyzed were age, gender, social situation, type of fracture, surgery performed, cognitive impairment, comorbidities, autonomy in activities of daily living, walking ability, depression, malnutrition, complications, functional gain, stay, efficiency, effectiveness and destination at discharge. The level of significance was set at p < 0.05.

Results:

A functional gain of 31.21 points, an efficiency of 1.04 and an effectiveness of 0.61 were obtained. The variables associated with functional gain ˂ 20 were respiratory infection (p = 0.02) and Pfeiffer ≥ 5 (p = 0.02), and with a functional gain higher than 20, Barthel index at admission was ≤ 20 (p = 0.00). Respiratory infection (p = 0.01) and Pfeiffer ≥ 5 (p = 0.04) were linked to efficiency ˂ 1; and at efficiency ˃ 1, arthroplasty as a surgical technique (p = 0.04). Malnutrition (p = 0.03) and Pfeiffer ≥ 5 (p = 0.02) were related to efficacy ˂ 0.5.

Conclusions:

Respiratory infection, cognitive impairment, functional status at admission, hip arthroplasty and malnutrition influenced the functional outcome.
