[The "Barthel Index": alternative to expertising in compulsory care insurance?].

Measuring the level of care needed is difficult and since the introduction of nursing care insurance in Germany in 1995 the assessment method applied by the MDK (Medizinischer Dienst der Krankenversicherung) has repeatedly been criticised. The method is very costly and not broadly tested for its validity and reliability. The question arises whether similar results can be obtained by applying another instrument, like the Barthel Index (BI), which is easier to use and more reliable. In this article the authors show - based on a preliminary study in 1999 - that by using the Barthel Index a discriminance analysis will show identical results in 80 % of all cases. The authors regard this identical measurement of care needs, which is reached by scoring only ten items (BI) versus thirty (MDK's assessment method) and with a presumingly higher reliability, as a major progress and reason enough for further discussion and studies of the use of the Barthel Index for care needs assessment.
