Purpose: To clarify the difference in mean gain of the Nichijo-seikatsu-kino-hyokahyo (NSKH; English translation: Functional Assessment of Daily Living Table) scores between the convalescent rehabilitation hospitals (CRHs) participating in the stroke liaison critical pathway.
Methods: The mean gain of NSKH score differs depending on patient type. Therefore, stroke patients were stratifi ed according to their total NSKH scores on admission to CRHs and the gains were calculated. Then adjusted mean gain was calculated for each hospital by correcting the mean gain assuming that the severity distribution in each CRH is the same as the severity distribution in all CRHs.
Results: The patients were stratifi ed into 10 groups based on the total NSKH scores on admission divided into intervals of two points. The number of patients in the group with 0-1 point was the largest, while the gain was generally large in the groups with 6 to 13 points and was the largest in the group with 8-9 point. The adjusted mean gain exceeded the mean gain in Hospital B that had more mildly impaired patients, while the adjusted mean gain was below the mean gain in the remaining hospitals that had many critically ill patients.
Conclusion: It is possible to make comparisons between hospitals, regions or years using the adjusted mean gain of NSKH score. Thus, this parameter seems to be useful in the assessment of outcome in CRHs participating in the stroke liaison critical pathway.
