Evaluation of preoperative patient education and computer-assisted patient instruction.

Health care practitioners believe that patient education enhances patients' compliance with treatment, their medical outcomes, and their quality of life. This study evaluated an existing method of noncomputerized structured preoperative education delivered by a nurse specialist and implemented and evaluated a computer-assisted instruction (CAI) tool for nonsurgical patients in the Vanderbilt Orthopaedic Spine Service. These patient education modalities were assessed with regard to the patient health concepts measured in the Short Form-36 Health Survey and, in addition, for preoperative education, with regard to the length of patient hospital stay. Preoperative education improved patient perceptions of vitality and mental health, increased length of stay for discectomy patients, and had no effect on length of stay for other surgical procedures. CAI improved patient perceptions of bodily pain.
