Objective：To clarify the effect of exclusion items on the KRW achievement index (KRW-AI) in the outcome evaluation of a convalescent rehabilitation ward.Methods：The subjects were 812 inpatients in a convalescent rehabilitation ward. The objective variable was the KRW-AI of 40 or less, and the explanatory variables were the items excluded from the KRW-AI and their combination for a total of eight categories, such as (1) low motor FIM, (2) high motor FIM, (3) low cognitive FIM, (4) elderly, (5) (1)＋(3), (6) (1)＋(4), (7) (3)＋(4), (8) (1)＋(3)＋(4). The adjusted variables were sex, rehabilitation calculation category, and time from onset to admission to the ward. Poisson regression analysis was performed. The Incidence Rate Ratio (IRR) and 95％ confidence interval (CI) were calculated.Results：Five of the eight exclusion categories were significantly associated with low-KRW-AI scores. The highest IRR was 2.29 (95％ CI：1.41-3.69, p＜0.001) for (2).Conclusion：High motor FIM are associated with a higher relative risk of falling below the KRW-AI of 40. Conversely, being older and the presence of cognitive disorder did not interfere with low-KRW-AI scores.
