OBJECTIVE: This non-blinded randomized controlled trial was the first phase of a planned series of investigations designed to test the efficacy of aggressive post-operative enteral nutrition support to decrease the rate of post-operative complications or improve long-term outcomes in specifically defined subgroups of elderly patients who have sustained a hip fracture requiring surgery. METHODS:Eighteen patients (17 males) were randomized to the treatment (eight male subjects) or control groups. The control group (mean age 76.5+/-6.1 years) received standard post-operative care. Subjects in the treatment group (mean age 74.5+/-2.1 years) received 125 cc/hour of nasoenteral tube feedings over 11 hours each night in addition to standard post-operative nutritional care. RESULTS: Both the treatment and control groups had reduced volitional nutrient intakes for the first 7 post-operative days (3,966+/-2,238 vs. 4,263+/-2,916 kJ/day [948+/-535 vs. 1019+/-697 kcal/day], p=0.815), but the treatment subjects had a greater total nutrient intake (7,719+/-2,109 vs. 4,301+/-2,858 kJ/day [1845+/-504 vs. 1028+/-683 kcal], p=0.012). On average, treatment subjects were tube fed for 15.8+/-16.4 days. There was no difference between the groups (treatment vs. controls) in the rate of post-operative life-threatening complications (25 vs. 30%, p=1.00) or in-hospital mortality (0 vs. 30%, p=0.216). Mortality within 6 months subsequent to surgery was lower in the treatment group compared to the controls (0 vs. 50%, p=0.036). DISCUSSION: We conclude that nightly enteral feedings are a safe and effective means of supplementing nutrient intake. The greatest impact of nutrition support may be to reduce mortality.
