An Interdisciplinary Team Approach to Decision-making About the Use of Psychotropic Medication for Individuals with Mental RetardationNatvig, Deborah A.; Department of Biobehavioral Nursing (1993-05)The purpose of this study was to examine a decision-making model for developing psychotropic medication plans for individuals w ith mental retardation. The study examined relationships among medication knowledge, acceptance of the interdisciplinary team (IDT) process, leadership, consensus, and the quality of the psychotropic medication plan. The study w as conceptualized using Henderson's Model for Nursing. Henderson (19 6 6 ) identified the nurse as an active participant on the IDT who helps plan and implement care designed to m eet the needs of the individual. T w o hundred eight (N = 208) team members from 4 9 interdisciplinary psychotropic medication review teams participated in th e study. Team s from all four large regional Intermediate Care Facilities for the M entally Retarded (ICFs/MR) in one southeastern state participated. Multiple regression and hierarchical multiple regression analyses were performed to test the hypotheses. The first hypothesis, that consensus would be predicted by medication knowledge, acceptance of the IDT process, and leadership w as partially supported. Leadership w as a significant predictor of consensus. The second hypothesis, that the quality of the psychotropic medication plan would be predicted by medication knowledge, acceptance of the IDT process, and leadership was not supported. The third hypothesis, which added consensus to the model, did not explain any additional variance in the quality of the psychotropic medication plan. As part of this study, The Psychotropic Review for Interdisciplinary Decisions and Evaluation (PRIDE) scale w as developed to assess the quality of psychotropic medication plans.

These included: small sample size, lack of independence of teams, low variability of responses to instruments, and multicollinearity. Psychotropic medication plans from some ICFs/MR were superior to those produced by others. Characteristics of the ICFs/MR, such as, the amount of guidance given to teams through written guidelines and policy, and the degree of administrative support reflected through availability of staff to participate in the review process, may have been the most significant factors influencing the quality of psychotropic medication plan produced.
