The objective of this study was to evaluate the ability of age and the American Society of Anesthesiologists (ASA) score to act as clinical indicators and predict clinical adversity after abdominal surgery. We evaluated 2570 patients who underwent abdominal surgery. The data were collected in a prospective manner with an unbiased measurement of the baseline risk and endpoint criteria. Age > 60 years and/or an ASA score > 2 identified over 80% of the patients who had a prolonged stay in hospital, developed intraperitoneal sepsis, were admitted to the ICU or died. This effect was additive which implies a useful degree of independence between the two risk factors. Age and the ASA score are useful indicators of clinical adversity and resource utilization after abdominal surgery. Hence, they can be used to benchmark the outcome of abdominal surgery between institutions.
本研究的目的是评估年龄和美国麻醉医师协会（ASA）评分作为临床指标的能力，并预测腹部手术后的临床不良情况。我们评估了2570例接受腹部手术的患者。数据以前瞻性方式收集，对基线风险和终点标准进行无偏测量。年龄>60岁和/或ASA评分>2可识别出超过80%住院时间延长、发生腹腔内感染、入住重症监护病房（ICU）或死亡的患者。这种效应是相加的，这意味着两个风险因素之间有一定程度的独立性。年龄和ASA评分是腹部手术后临床不良情况和资源利用的有用指标。因此，它们可用于衡量不同机构之间腹部手术的结果。
