A prospective assessment of nutritional status and complications in patients with fractures of the hip

Abstract

A group of 40 consecutive patients with hip fractures were studied and confirmed to have a high incidence of protein-calorie malnutrition. The prospective nutritional assessment performed for this study included: serum albumin, serum transferrin, anthropometric measurements, skin testing for delayed hypersensitivity, total lymphocyte count, and a 24-h urine collection for metabolic and nitrogen balance determinations. At 3 months after their hip fracture, 37.5% returned to their premorbid ambulatory status; 42.5% sustained a decrement in their ambulatory status or independence; 12.5% died; 7.5% were lost to follow-up. Of the nutritional parameters studied, albumin was significantly associated with mortality (p = 0.004). Considering those patients with an albumin less than 3.0, a mortality rate of 70% was observed in follow-up (maximum of 11 months), compared with a mortality rate of 18% in patients with an albumin greater than or equal to 3.0. It is concluded that the serum albumin has value as a nutritional index without specialized nutritional parameters, and that a more aggressive approach to nutritional support is needed for the hypoalbuminemic patient with a hip fracture, particularly for those with a serum albumin below 3.0.
