A primary role of the registered dietitian (RD) is to assess nutritional needs of patients in states of physiological stress and illness and to recommend changes to diet and tube feedings when warranted. However, implementation of changes is dependent upon the physician accepting the recommendations of the RD. This study evaluated outcomes of two groups of enterally fed patients in a long-term acute-care facility in northwest Louisiana: (a) those for whom the physician accepted RD recommendations; and (b) those for whom the physician did not accept RD recommendations. Data showed that physician-prescribed enteral formulas provided 10.0% less kilocalories and 7.8% less protein than the RD-assessed needs. t tests showed that when RD recommendations were implemented, patients had a significantly shorter length of stay (28.5+/-1.8 vs 30.5+/-4.8 days, P<0.05), as well as significantly improved albumin (0.13+/-0.17 vs -0.44+/-0.21 g/dL [1.3+/-1.7 vs -4.4+/-2.1 g/L], P<0.05) and weight gains (0.51+/-0.1 vs -0.42+/-0.2%, P<0.05) when compared to those who continued with physician's orders. These data suggest that if RDs had the authority to write nutrition orders and provide early nutrition intervention, patient care would improve.
注册营养师(RD)的主要职责是评估处于生理应激和疾病状态患者的营养需求,并在必要时建议调整饮食和管饲。然而,这些调整的实施取决于医生是否接受注册营养师的建议。本研究评估了路易斯安那州西北部一家长期急性护理机构中两组肠内喂养患者的结果:(a)医生接受注册营养师建议的患者;(b)医生不接受注册营养师建议的患者。数据显示,医生开出的肠内配方提供的千卡热量比注册营养师评估的需求少10.0%,蛋白质少7.8%。t检验表明,当实施注册营养师的建议时,与继续遵循医生医嘱的患者相比,患者的住院时间显著缩短(28.5±1.8天对30.5±4.8天,P<0.05),白蛋白水平显著改善(0.13±0.17对-0.44±0.21g/dL[1.3±1.7对-4.4±2.1g/L],P<0.05),体重增加也更显著(0.51±0.1对-0.42±0.2%,P<0.05)。这些数据表明,如果注册营养师有权开具营养医嘱并提供早期营养干预,患者护理将会得到改善。
