Pre-operative anxiety variables as possible predictors of post-operative stay in hospital.

The extent to which measures of pre-operative anxiety predict post-operative hospital stay, over and above what is predicted by biographical, medical status and post-operative anxiety variables, was examined in 81 cholecystectomy patients. Hierarchical multiple regression analysis revealed that patients who were older, had lower health status and suffered from wound infection, had a longer post-operative hospital stay than others. None of the pre-operative anxiety measures had a significant incremental value in the prediction of the post-operative hospital stay.
