Research problems for consultation-liaison psychiatry in the DRG era.
Psychiatry needs to conduct more rigorously designed empirical research studies to demonstrate its cost-effectiveness, especially since the DRG era is becoming more firmly established. The effectiveness of psychiatric intervention can be evaluated on its abilities to improve physical functioning as well as its improvement of psychosocial symptoms and cost savings. Some of the problems in consultation-liaison research are discussed, including the potentially confounding influences of demographic variables, type and severity of somatic disease, time since diagnosis, level of psychosocial stress, and initial level of physical functioning. Several types of research measures used in assessing physical and psychosocial functioning are discussed, and some of the dilemmas for psychiatry in utilizing individual versus standardized research interventions are explored.
