The aim of this study to assess the impact of nutritional support guided by repeated measurements of REE in geriatric patients following surgery for hip fractures.
Our hypothesis is that tight caloric control will reduce the risk of significant postoperative complications in geriatric patients following surgery for hip fractures.
Study Design :Prospective, Single center, Randomized, Unblinded study. Study Population:geriatric patients following surgery for hip fractures.
The primary outcome:
presence of postoperative complications,hospital length of stay.
Secondary outcomes:
energy intake and calculated energy balance
Study Procedure:
eligible patients will be randomly assigned to 2 groups: the tight calorie (intervention)group and the control group.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Group 2 (Control group) | No Intervention | Group 2(Control group)-patients in this group received nutrition according to the standard hospital dietary regimen. | |
| Group 1 (Indirect Calorimetry) | Experimental | Group 1(Indirect Calorimetry)-The tight calorie group received calories with an energy goal determined by repeated REE measurements using indirect calorimetry. |
|
| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| Indirect Calorimetry | Other | The tight calorie group received calories with an energy goal determined by repeated REE measurements using indirect calorimetry. IC measurements:after a fasting period of at least 6 hours at three time periods : on admission to the study,between 24-48 hours following surgery and on the 7th day of the study.Measurements were performed by an experienced nurse or dietician,the device was automatically calibrated before each measurement and the REE was recorded after 15 minutes. |
| Measure | Description | Time Frame |
|---|---|---|
| Rate of postoperative complications | incidence of postoperative complications following admission up to day 14/or hospital discharge and length of hospital stay will be evaluated | up to day 14 |
| Measure | Description | Time Frame |
|---|---|---|
| Energy balance | energy intake and calculated energy balance. | prior to surgery and up to 14 day |

Inclusion Criteria:
patients older than 65 years who were admitted to the unit following hip fracture within 48 hours of the injury and in whom orthopedic surgery was considered the treatment of choice.
Exclusion Criteria:
Patients were excluded if they presented to hospital > 48 hours after the injury, were receiving steroids and/or immunosuppression therapy; in the presence of active oncologic disease, multiple fractures, diagnosed dementia or in the event that patients required supplemental nasal oxygen which precludes the measurement of resting energy expenditure.
