大腿骨近位部骨折患者の入院時栄養評価と日常生活動作の改善および自宅復帰率との関連性

The relationship between nutritional assessment on admission, improvement of ADL, and rate of home return in hip fracture patients

要旨：本研究では，回復期リハビリテーション病棟に入院した大腿骨近位骨折患者を対象に，GNRIを用いた栄養評価を行い，入院時栄養状態が退院時の日常生活動作の改善具合や自宅復帰の可否の予測に有用であるか検討した．その結果，入院時栄養状態が良好であればFIMの清拭や移動，階段は改善するが，自宅復帰率との関連性は認めなかった．GNRIを用いた入院時栄養評価は，高齢の大腿骨近位部骨折患者の特定のADLの予後予測には有用であるが，自宅復帰率の予測には適さない可能性が示唆された．

　The geriatric nutritional risk index (GNRI) is a well-established tool to assess nutritional risk. We assessed the association between GNRI, ADL, and the rates of returning home for hospitalized patients with proximal femur fractures. Results indicated that patients with high-GNRI scores significantly improved Grooming, Walking/Wheelchair, and Stairs on the Functional Independence Measure. However, there was no correlation between GNRI and the rate of returning home on the Logistic Regression Analysis. GNRI scores can predict the improvement of ADL for geriatric patients with proximal femur fractures.
