[Evaluation and improvement of medical and nursing service and caregiving for the elderly using MDS. 3. Revised recording system of diagnoses and symptoms suitable for use in Japan].

ABSTRACT

Diagnoses and symptoms are recorded by physicians in the chapter E of the Minimum Data Set (MDS), if they are relevant to disabilities of activities of daily living, cognition, behavior, medical treatments or risk of death. We improved the chapter so that it is suited to disease patterns in Japan in a format useful not only for nursing and ADL care but for medical treatment in our practice. In E1, diseases directly underlying the current disability states were recorded in the international classification of Disease, 9th Revision (ICD9). In 24, 670, 195, and 45 patients respectively, there were 0, 1, 2, and 3 separate recorded diseases. A Total of 63 ICD9 codes were observed, but only four codes; 290, 332, 431, and 434, were underlying diseases for 3% or more patients. These codes included mostly ischemic and degenerative disease of the brain.
