Preoperative evaluation of alcohol consumption in older patients

Abstract

Abstract Purpose This sub-analysis of the PROPDESC-study (Pre-Operative Prediction of postoperative delirium by appropriate Screening-study) evaluated the alcohol consumption of older patients with two different assessment tools (single sentence question and Alcohol Use Disorder Identification Test-Consumption (AUDIT-C)) and compared the results in regards to detection, reliability, and quantification of patient´s alcohol consumption. Methods During their anesthesiological pre-clinic visit 1084 patients older than 59 years were asked whether they consume alcohol daily and 668 of them additionally answered the AUDIT-C questionnaire. Results According to the SSQ 11.72% of the patients consumed alcohol daily. In the AUDIT-C sub-group 25.90% reported moderate to high alcohol consumption while infrequent or very low alcohol intake was reported by 41.92%. In the subgroup 31.89% of the patients stated alcohol abstinence. About one quarter (25.13%) of patients who denied daily alcohol intake but scored positive on the AUDIT-C displayed levels of alcohol consumption ranging from moderate (11.20%) to high (13.87%) according to the AUDIT-C. Conclusion Reliable information about alcohol consumption is related to the method of questioning. The AUDIT-C evaluates the patient´s alcohol intake precisely and identifies more older patients with possibly health- and surgery-relevant alcohol consumption levels. The validated AUDIT-C provides an objective assessment to the physician during the pre-clinic anesthesiologic consultation. Additionally, handing out a questionnaire to the patient encourages initiative and self-assessment and could also relieve both, the physician and the patient from sensing a moral evaluation of alcohol consumption.
