Despite the benefits of modest weight reduction for overweight patients with chronic liver disease, long-term maintenance of weight loss is difficult to achieve in clinical practice. The aims of this study were to determine if a nutrition research protocol could be translated into clinical practice and meet the demand for dietetic service, to evaluate the effectiveness and resource implications of intensive lifestyle intervention for weight loss, and to assess the effectiveness of standard dietetic therapy as a treatment option for patients unable to attend the program.
Using a modified research protocol, an intensive weight reduction program was introduced into standard clinical care for overweight patients attending a tertiary hospital liver outpatient clinic. An audit of weight loss and cost outcomes was conducted.
Ninety-three patients were referred to the dietetic service for weight management. Of these, 50 enrolled in an intensive lifestyle intervention, 18 received standard dietetic therapy and 25 refused any intervention. After 6 months, 83% of patients in the intensive intervention achieved weight loss with a significant decrease in weight (P < 0.001) and waist circumference (P < 0.001). In contrast, only 24% of patients receiving standard dietetic therapy achieved weight loss with no significant change in mean weight or waist circumference. Cost per kilogram weight loss after intensive intervention was $AU31 and continuation of lifestyle intervention was calculated to be less than $AU100 per patient per year.
A clinically based, intensive lifestyle intervention is a feasible treatment option for outpatient weight management in overweight patients with chronic liver disease. Providing patients who are unable to participate in intensive programs with standard dietetic therapy is not cost-effective.
尽管适度减重对患有慢性肝病的超重患者有益,但在临床实践中难以长期维持体重减轻。本研究的目的是确定一项营养研究方案能否转化为临床实践并满足饮食服务需求,评估强化生活方式干预对减重的有效性及资源影响,以及评估标准饮食疗法作为无法参加该项目患者的治疗选择的有效性。
采用改良的研究方案,将强化减重项目引入一家三级医院肝病门诊超重患者的标准临床护理中。对减重和成本结果进行了审计。
93名患者被转介至饮食服务部门进行体重管理。其中,50名患者参加了强化生活方式干预,18名接受了标准饮食疗法,25名拒绝任何干预。6个月后,强化干预组83%的患者实现了体重减轻,体重(P < 0.001)和腰围(P < 0.001)显著下降。相比之下,接受标准饮食疗法的患者中只有24%实现了体重减轻,平均体重和腰围无显著变化。强化干预后每减轻一公斤体重的成本为31澳元,继续进行生活方式干预的成本计算为每年每名患者不到100澳元。
基于临床的强化生活方式干预是超重慢性肝病患者门诊体重管理的一种可行治疗选择。为无法参加强化项目的患者提供标准饮食疗法不具有成本效益。
