Surgical patients' attitudes regarding participation in clinical anesthesia research.

We designed a questionnaire to identify the factors influencing both day of admission surgery (DAS) and ambulatory (AMB) patients in their decision whether to participate in and give informed consent for clinical anesthesia research. On the day of surgery, 276 patients were approached to complete a questionnaire and a visual analog scale (VAS) to assess anxiety. The data collected were observational and are presented as percentages for each group (DAS and AMB). One hundred eighty-two patient (60 DAS and 122 AMB) completed questionnaires. Both DAS and AMB patients desired 20-30 min to read a consent form. Preferred conditions for enrollment by both groups were as follows: interview at the time of preadmission testing; after consulting with their physician; in a private setting while dressed in street clothes; and with assurance that the investigator would also participate in the study, if eligible. Unacceptable conditions were as follows: research associated with any risk and interview in the operating room holding area. All patients responded that they were capable of making the decision whether to participate in research on the day of surgery. Most AMB and DAS patients found it acceptable to be recruited on the day of surgery, if approached appropriately.
