An index of clinical oral disorder in elders (CODE)

Attempts to construct an index of oral health or disorder suitable for older adults have been limited in clinical scope or based on the judgement of very few individuals. Consequently, we present here a multidimensional index of Clinical Oral Disorder in Elders (CODE) based on a breadth of clinical measures relevant to elders. The data for the index are derived from a clinical examination of jaw function, dentures, mucosa, teeth, and periodontium. Weighting or ranking for each disorder within the context of an elderly person was established as mild, moderate or severe by experienced dental clinicians and dental hygienists. Subsequently, the index was constructed by transforming the weights into a numerical value for each clinical measure. Individual scores can relate to the heaviest weight identified during the examination or to the sum of the weights assigned throughout the examination, and the average score during a series of examinations will reflect the clinical status of a particular population. Clinical applications in elderly residential-care populations indicate that the index can be constructed efficiently and with reasonable reliability. We suggest, therefore, that the CODE index is suitable for descriptive and comparative research by providing a clinical format for measuring oral disorder in disabled elders, and, when combined with a psychosocial index, it should be very comprehensive indicator of oral dysfunction in older adults.
