Most scoring systems used to predict mortality are complex. A simple preoperative assessment, the Sickness Assessment (SA), was evaluated as a predictor of mortality in elderly patients admitted as surgical emergencies. The three parameters comprising the SA are: hypotension on admission, the presence of severe chronic disease, whether the patient was independent and self-caring. Prospectively, 487 consecutive patients of over 65 years of age admitted as surgical emergencies were studied. On admission, the SA and the APACHE II score were calculated. Hospital mortality was used as the endpoint. Of 309 patients with zero SA, 21 (7%) died. In 178 with a positive SA, 64 died (36%) (chi 2 = 64.6, P < 0.001). After laparotomy, mortality was 57% (36/67) with a positive SA, but 15% (15/103) with a zero assessment (chi 2 = 33.6, P < 0.001). When the single parameter of hypotension on admission was present, mortality was 77% (23/30). The predictive ability of the APACHE II score was not superior to SA. The SA is a simple preoperative assessment which identifies a high-risk group. It should be used in emergency surgical practice to improve outcome and avoid inappropriate surgery.
大多数用于预测死亡率的评分系统都很复杂。一种简单的术前评估方法,即疾病评估(SA),被作为手术急症入院老年患者死亡率的预测指标进行了评估。构成SA的三个参数是:入院时低血压、严重慢性病的存在情况、患者是否独立自理。前瞻性地研究了487例连续入院的65岁以上手术急症患者。入院时计算SA和急性生理与慢性健康状况评分系统II(APACHE II)得分。以医院死亡率作为终点指标。在309例SA为零的患者中,21例(7%)死亡。在178例SA为阳性的患者中,64例死亡(36%)(卡方=64.6,P<0.001)。剖腹手术后,SA为阳性的患者死亡率为57%(36/67),而评估为零的患者死亡率为15%(15/103)(卡方=33.6,P<0.001)。当存在入院时低血压这一单一参数时,死亡率为77%(23/30)。APACHE II评分的预测能力并不优于SA。SA是一种简单的术前评估方法,可识别高危人群。在急诊手术实践中应使用该方法以改善预后并避免不适当的手术。
