Client-nurse interaction: testing for its impact in preoperative instruction.

This study tests for the impact of client-nurse interaction, an essential element lacking in earlier research on preoperative instruction. An experimental design compared the effects of three models of intervention: Facilitator, Informational and Routine Treatment on postoperative pain and anxiety in 91 cholecystectomy patients. Planned comparisons showed that subjects in both experimental conditions reported significantly less postoperative anxiety than subjects who received the routine treatment. There were no differences in anxiety levels between the two experimental groups or in pain scores among the three groups. Refinements in the facilitator model are recommended to enhance the problem-solving nature of the interaction and to strengthen future research. The findings support the importance of providing the patient with sensation information and postoperative exercise instruction.
