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.
