This chapter covers pre-screening, history and physical for evaluation of patients who are potential candidates for procedures under sedation, as well as instructions for patients. Patients for elective procedures may be referred by their primary care physician or may be self-referred. Screening, evaluation, and instruction of patients requires clinical experience, and clerical staff members should not be performing any more than simple initial screening or instructing patients as to time, location, and routine standard instructions. The scope of practice of the surgeon/practitioner/physician(s) involved and the individual facility determine the range of procedures possible. The setting may be quite flexible and general (an operating room) or very specifically designed and equipped. Procedures should be scheduled in locations equipped both for the procedure and for sedation and any contingencies that can be routinely expected as a result of either the procedure or the patient.
