老年人营养不良筛查和评估初始量表的构建

Development of a preliminary version of screening and assessment tool for malnutrition in the elderly

目的构建适用于我国老年人的营养不良筛查和评估初始量表。方法通过查阅文献,专家小组讨论,制定量表备选条目池。采用德尔菲专家咨询法,邀请老年医学及相关专业的专家,通过Email的方式发放专家咨询问卷(共两轮)。专家对各条目的重要性进行评分,并请专家对做出重要性评分的判断依据及对条目内容的熟悉程度进行评分。计算各条目的重要性得分、变异系数和满分比例,结合专家意见筛选条目,形成初始量表。结果两轮咨询分别回收专家咨询问卷16份和15份,专家积极系数为100%和93.75%。第一轮咨询筛查和评估量表专家权威系数为0.96±0.05和0.95±0.06,条目的重要性得分为4.53±0.19和4.19±0.38,变异系数为(19.38±4.89)%和(24.67±8.47)%,满分比例为(72.62±12.12)%和(51.39±17.19)%,Kendall协调系数为0.429和0.381(P<0.001)。第二轮咨询筛查和评估量表专家权威系数为0.96±0.06和0.95±0.06,条目的重要性得分为4.65±0.20和4.60±0.25,变异系数为(13.37±6.23)%和(14.43±6.56)%,满分比例为(73.83±15.03)%和(71.24±17.36)%,Kendall协调系数为0.319和0.228(P<0.001)。根据得分情况和专家意见,最终筛查初始量表入选10个条目,评估初始量表入选17个条目。结论通过德尔菲法构建了包含10个条目和17个条目的老年人营养不良筛查和评估初始量表。

Objective To develop a preliminary version of screening and assessment tool for malnutrition in Chinese elderly.Methods An item pool was established after literature review and panel discussion.The items were screened by using Delphi method.Experts in geriatrics and related regions were invited.Two rounds of survey questionnaire were implemented by form of Email.Experts were required to evaluate the items in terms of their importance and provide basis of judgement and degree of familiarity.A preliminary version of screening and assessment tool was determined after the items were screened according to average importance value,coefficient of variation and full score ratio.Results Sixteen and fifteen survey questionnaires were completed for the two rounds of consultation and the coefficients of positivity were 100%and 93.75%.In the first round,the degrees of authority were 0.96±0.05 and 0.95±0.06,the average importance scores of items being 4.53±0.19 and 4.19±0.38,the coefficients of variation being(19.38±4.89)%and(24.67±8.47)%,the full score ratios being(72.62±12.12)%and(51.39±17.19)%,and Kendall coordination coefficients being 0.429 and 0.381(P<0.001)for screening and assessment questionnaire.In the second round,the degrees of authority were 0.96±0.06 and 0.95±0.06,the average importance scores of items being 4.65±0.20 and 4.60±0.25,the coefficients of variation being(13.37±6.23)%and(14.43±6.56)%,the full score ratios being(73.83±15.03)%and(71.24±17.36)%,and Kendall coordination coefficients being 0.319 and 0.228(P<0.001)respectively.Based on the scores and expert opinions,10 items were finally selected for the screening tool and 17 items for the assessment tool.Conclusions A preliminary version of screening and assessment tool is established which consists of 10 items and 17 items respectively for malnutrition in the elderly by Delphi method.
