BackgroundSince October 2004 German Anaesthesiology Societies have officially recommended a decreased fasting period of 2 h for clear fluids and 6 h for solid food before elective surgery. A survey of patients and health care workers was carried out in our university clinic to assess the implementation of the new fasting recommendations.MethodsSurgical patients (n=865) as well as physicians and nurses specialized in anaesthesia and surgery (n=2,355) were invited to complete a written questionnaire. The survey inquired about prescribed and practiced duration of fasting, attitudes towards reduced preoperative fasting and knowledge of the new guidelines.ResultsData from 784 patients (91%) and 557 health care workers (24%) were analysed. Patients reported mean fasting times of 10+/-5 h for fluids and 15+/-4 h for solid food. Of the patients 52% and 16% would have preferred to drink and eat before surgery, respectively and 10% were informed about the new recommendations of shorter preoperative fluid and solid fasting. Such patients reported significantly reduced fasting times for fluids compared with those who were recommended to fast for the traditional longer periods (8+/-6 versus 12+/-4 h, p<0.001). Preoperative fasting advice remembered by the patients significantly differed from the prescribed recommendations (2 h fluid fasting, 22 versus 53%, p<0.001). Anaesthesiologists were significantly more knowledgeable of the new guidelines (90 versus 32-42%, p<0.001) and significantly more willing to recommend the new short preoperative fasting times (75 versus 15-19%, p<0.001) than other health care workers. Of all health care workers 82% and 32% reported patients' frequent desire to drink and eat before surgery, respectively, 92% considered reduced preoperative fasting to be positive, 76% feared increased risks for patients and 42% expected a decreased flexibility in their daily work.ConclusionThe current guidelines for preoperative fasting have not been widely implemented. Besides a knowledge discrepancy, remarkable concerns remain regarding higher risk for patients which may be important barriers to implementation. Nevertheless, health care workers are aware of patients' desire for shorter preoperative fasting. If the new guidelines are recommended patients will make use of them. Further training of staff and adequate implementation tools are needed.
