To compare measurement accuracy of test forms with varied number of items (13, 8, and 4 items) generated from the self-care physical function item bank composed of Functional Independence Measure (FIM™) and the Minimum Data Set (MDS).
Retrospective data analysis of 2499 Veterans who completed both FIM and MDS within 6 days. We compared measurement accuracy between the converted FIM (FIMc) motor score generated from the MDS and the original FIM (FIMa) motor score (13 items) at: (a) individual-level using point differences, and (b) group-level using function-related group (FRG).
The differences of mean FIMa and FIMc scores were between 0.05 and 1.07 points for all test forms. Over 81% of FIMc from MDS_13 were within 15 points of the FIMa. 81-90% of FRGs generated by the FIM short forms was identical to those generated by the FIMa for stroke, lower limb amputation, knee and hip replacement; and 59.9-90.5% by all MDS test forms. All MDS test forms had above 74% agreement with same or adjacent FMGs (ICC 0.65-0.91).
The accuracy is dependent on the comparison level (i.e., individual or group), length of the test and which FRG is used. Our results partially support using existing instruments-without decreasing the number of the items-to generate a continuum of care measurement.
比较由功能独立性测量（FIM™）和最小数据集（MDS）组成的自我护理身体功能项目库生成的不同项目数量（13项、8项和4项）的测试形式的测量准确性。
对2499名在6天内完成FIM和MDS的退伍军人进行回顾性数据分析。我们在以下方面比较了从MDS生成的转换后的FIM（FIMc）运动评分与原始FIM（FIMa）运动评分（13项）之间的测量准确性：（a）使用点差在个体水平上进行比较，（b）使用功能相关组（FRG）在组水平上进行比较。
所有测试形式的FIMa和FIMc平均得分差异在0.05至1.07分之间。MDS_13中超过81%的FIMc与FIMa相差在15分以内。FIM简短形式生成的FRG中，81%-90%与中风、下肢截肢、膝关节和髋关节置换的FIMa生成的FRG相同；所有MDS测试形式生成的FRG为59.9%-90.5%。所有MDS测试形式与相同或相邻的FMG的一致性均高于74%（组内相关系数ICC为0.65-0.91）。
准确性取决于比较水平（即个体或组）、测试长度以及使用的FRG。我们的结果部分支持在不减少项目数量的情况下使用现有工具来生成连续的护理测量。
