Data literature lacks of evidence concerning the variation of the nutritional status in patients undergoing hip surgery, thus preventing an effective application a nutritional support program. It is therefore necessary to start identifying the clinical steps (pre-operative and post-operative) that may be defined as critical control points for malnutrition. The observation should foresee the identification of nutritional status indicators, such as weight, hemoglobin, albumin, food intake, and others that might affect a proper recovery. This study aims to investigate the prognostic nutritional factors that might influence clinical outcomes, and their variation in relation to hospitalization and rehabilitation periods.

It is therefore necessary to start identifying the clinical steps (pre-operative and post-operative) that may be defined as critical control points for malnutrition. Patients undergoing hip surgery would be enrolled before the surgical operation and would be evaluated three times: preoperative, postoperative, and after discharge. The observation should foresee the identification of nutritional status indicators, such as weight, hemoglobin, albumin, food intake, and others that might affect a proper recovery. This study aims to investigate the prognostic nutritional factors that might influence clinical outcomes, and their variation in relation to hospitalization and rehabilitation periods.

Change from baseline level of hemoglobin at 14 days after surgical operation
One of the main decision-making factors that guide the clinician to discharge the patient is the hemoglobin level. The association between preoperative hemoglobin and hemoglobin at discharge was already observed in past orthopedic cohorts, with a loss of 3.3 g/dl being considered clinically relevant. Patients with a better nutritional status may have a reduced fall in hemoglobin after the surgical operation.

Change from baseline level of pre-albumin at 14 days after surgical operation
Pre-albumin (mg/dl)

Total lymphocyte count (cells/mm\^3)
Time frame: Before the surgical operation, after 3 days, after 14 days.
Change from baseline level of iron at 14 days after surgical operation

Time frame: Before the surgical operation, after 3 days, after 14 days.
Change from baseline of hand-grip strength at 14 days after surgical operation
Hand-grip strength (kg). For this test, the higher values, the better is.
Time frame: Before the surgical operation, after 3 days, after 14 days.
Change from baseline of FIM test at 14 days after surgical operation

Time frame: Before the surgical operation, after 3 days, after 14 days.
Change from baseline of 10 meter walking test at 14 days after surgical operation
10 meter walking test (m/s). For this test, the higher values, the better is.
Time frame: Before the surgical operation, after 3 days, after 14 days.
Change from baseline of POMA at 14 days after surgical operation
Performance Oriented Mobility Assessment (POMA) (0-32 point scale). For this test, the higher values, the better is.
Time frame: Before the surgical operation, after 3 days, after 14 days.
