To determine, in critically ill patients at risk, both the clinical utility and cost-effectiveness of using an air suspension bed in the prevention of pressure ulcers.
Randomized, parallel group, controlled clinical trial with accompanying cost-effectiveness analysis.
30-bed multidisciplinary intensive care unit.
100 consecutive patients at risk for the development of pressure ulcers randomly assigned to receive treatment on either an air suspension bed or a standard intensive care unit bed. Patients considered at risk were those at least 17 years of age with an Acute Physiology and Chronic Health Evaluation II (APACHE II) score greater than 15 who had an expected intensive care unit stay of at least 3 days.
The development of pressure ulcers by site and severity and the costs associated with each of the two programs.
The air suspension bed was associated with fewer patients developing single, multiple, or severe pressure ulcers. In patients at risk, the use of an air suspension bed in the prevention of pressure ulcers was a cost-effective therapy.
Despite intense nursing care, pressure ulcers are more prevalent in the critically ill patient population than in the general hospital population. Air suspension therapy provides a clinically effective means of preventing pressure ulcers in these patients. In patients at risk, air suspension therapy was a cost-effective means of managing pressure ulcers compared with the standard hospital bed.
确定在有风险的危重症患者中，使用气悬浮床预防压疮的临床效用和成本效益。
随机、平行组、对照临床试验，并进行成本效益分析。
拥有30张床位的多学科重症监护病房。
100例连续的有发生压疮风险的患者，随机分配接受气悬浮床或标准重症监护病房床位的治疗。被认为有风险的患者是年龄至少17岁、急性生理与慢性健康状况评分系统II（APACHE II）得分大于15且预计在重症监护病房住院至少3天的患者。
按部位和严重程度划分的压疮发生情况以及两个方案各自的相关成本。
气悬浮床与发生单个、多个或严重压疮的患者较少相关。在有风险的患者中，使用气悬浮床预防压疮是一种具有成本效益的治疗方法。
尽管进行了强化护理，但压疮在危重症患者群体中比在普通医院患者群体中更为普遍。气悬浮疗法为预防这些患者的压疮提供了一种临床有效的方法。与标准医院病床相比，气悬浮疗法对于有风险的患者而言是一种具有成本效益的压疮管理方法。
