The effects of different nutritional measurements on delayed wound healing after hip fracture in the elderly.
BACKGROUND
It has been well recognized that malnutrition causes wounds to heal inadequately and incompletely. Malnutrition is often observed in the elderly, and it appears to be more severe in patients with hip fracture than in the general aging population. Few prospective studies give a detailed account of the identification and classification of nutritional status in the elderly. The objective of this study was to evaluate the effects of different nutritional measurements on wound healing status after hip fracture in the elderly.


METHODS
From September 2002 to December 2007, 207 hip fracture patients older than 60 y treated surgically were reviewed for preoperative nutritional status. There were 81 males and 126 females with an average age of 75.93 y (62-91 y); 131 cases with femoral neck fractures, 76 cases with intertrochanteric fractures. Parameters indicative of nutritional status (serum albumin, serum transferrin, serum pre-albumin, and total lymphocyte count levels) at the time of admission were assessed, along with anthropometric measurements, Rainey MacDonald nutritional index, and MNA tool. Suture removal was performed on postoperative day 14.


RESULTS
Delayed wound healing complicated 46 (22.2%) of the 207 cases. The preoperative serum transferring total lymphocyte count levels, MNA total score, and Rainey MacDonald nutritional index were significantly lower for patients who subsequently had delayed wound healing. When all variables were subjected to multivariate analysis, only total lymphocyte count levels and MNA total score showed significant value in predicting which patients would have delayed wound healing. Through prophylactic antibiotics and adherence to strict aseptic precautions, on follow-up, wound healing was normal in all patients.


CONCLUSIONS
Patients at risk for delayed wound healing problems after hip fracture can be identified using relatively inexpensive laboratory test such as TLC and MNA tool. The clinician must be aware of the risk values of both measurements. We believe this information is particularly important before planning procedures of hip fractures in the elderly.
