The multidiscipline credentialed health care worker is an alternative to the current status of health care workers and worksites. Practitioners and educators in health care delivery are unable to reach a consensus as to the number of disciplines. Existing educational programs offer a wide range of programs enabling persons to attain health professional status and/or pursue credentials. A nationwide effort to gain licensure by numerous allied health disciplines has encouraged discipline-specific efforts to substantiate the need for licensure. The demand for accountability has led to the need to display cost efficiency while maintaining quality health care. Credentialed in at least two disciplines, the multidiscipline credentialed health care worker should be able to provide competent services in a more cost-effective manner than two single-discipline prepared persons. Some dimensions of the current situation are supportive of the concept--considerations of the individual, and the educational processes including the educator, the disciplines, and the employers. Unresolved dimensions are realistic discipline combinations and the level of preparation at which it is realistic to pursue dual credentialling. Multidisciplinary and interdisciplinary education are different, but some of the needs of the interdiscipline approach could be met by the multidiscipline design. (YLB)
