The specific contribution of dementia towards mortality in trauma patients is not well defined. The purpose of the study was to evaluate dementia as a predictor of mortality in trauma patients when compared to case-matched controls.
A 5-year retrospective review was conducted of adult trauma patients with a diagnosis of dementia at an American College of Surgeons-verified level I trauma center. Patients with dementia were matched with non-dementia patients and compared on mortality, ICU length of stay, and hospital length of stay.
A total of 195 patients with dementia were matched to non-dementia controls. Comorbidities and complications (11.8% vs 12.4%) were comparable between both groups. Dementia patients spent fewer days on the ventilator (1 vs 4.5, P = 0.031). The length of ICU stay (2 days), hospital length of stay (3 days), and mortality (5.1%) were the same for both groups (P > 0.05).
Dementia does not appear to increase the risk of mortality in trauma patients. Further studies should examine post-discharge outcomes in dementia patients.
痴呆症对创伤患者死亡率的具体影响尚不明确。本研究的目的是评估与病例匹配的对照组相比，痴呆症作为创伤患者死亡率预测指标的情况。
对美国外科医师学会认证的一级创伤中心诊断为痴呆症的成年创伤患者进行了为期5年的回顾性研究。将痴呆症患者与非痴呆症患者进行匹配，并比较其死亡率、重症监护病房住院时间和住院时间。
共有195例痴呆症患者与非痴呆症对照组进行了匹配。两组的合并症和并发症（11.8%对12.4%）相当。痴呆症患者使用呼吸机的天数较少（1天对4.5天，P = 0.031）。两组的重症监护病房住院时间（2天）、住院时间（3天）和死亡率（5.1%）相同（P > 0.05）。
痴呆症似乎不会增加创伤患者的死亡风险。进一步的研究应检查痴呆症患者出院后的结局。
