Von der Funktion zur Versorgung: Der Barthel-Index als Annäherung an den Pflegegrad

Based on anonymized inpatient service data from 2023 using the InEK-DatenBrowser (according to § 21 KHEntgG), the correlation between restrictions in the activities of daily living - measured with the Barthel Index - and the assigned level of care was examined. The aim was to demonstrate that the Barthel Index can be used as a practical tool for assessing the need for care in everyday medical practice. The results show that a lower Barthel Index is significantly associated with a higher level of care. Using ordinal logistic regression analyses (OR for level of care>1 are between 1.40 and 14.52) and the Kendall correlation test (τ=0.32; p<0.001; Cohen's d=1.10) we were able to demonstrate a statistically significant correlation. Thus, the Barthel Index can be used as an indicator for care needs - especially in cases where no formal level of care has yet been assigned. These findings can support medical decision-making and contribute to more needs-based care. Additionally, they could potentially ease physicians' daily routines by enabling the early identification of a need for long-term care.
