The questionnaire was developed by anesthesiologists and a nurse practitioner to increase pre-procedure awareness of relevant medical concerns, guide scheduling of procedures at outpatient versus inpatient locations, and improve patient pre-procedure management. The response rate after one year was 57% and indicated that at least 1 in 10 patient histories required review and discussion by the care team. The most common concerns were shortness of breath (8%), difficult airway (3%) and syncope (3%). Most procedures proceeded as scheduled, however, 18 procedures (0.4% of patients who responded), had to be rescheduled from an outpatient to the inpatient site due to medical concerns. The electronic pre-procedure screening has been feasible to implement at a busy clinical practice and has improved team communication, patient preparedness, and scheduling at appropriate locations.
