目的：有助于确认的Braden量表在患者入住ICU.Design的可靠性和预测效度的分析基础上，进行了分析，观察，纵向前瞻性研究设置：重症监护室，Virgen del Rocio医院，塞维利亚（西班牙）。患者：患者年龄在18岁或以上，并承认超过24小时的ICU被纳入。排除了入院时有压疮的患者。共335名患者参加了两个研究阶段，每个阶段一个月。干预措施：无。感兴趣的变量：存在的i-iv级压疮被视为主要或因变量。三类被认为是（人口统计学，临床和预后）为其余variables.Results：压疮患者的发病率为8.1%。I级和II级压疮的比例分别为40.6%和59.4%，强调骶骨是最常见的受累部位。Cronbach的α系数的评估认为，良好的中度可靠性。在所做的三次评价中，在入院第一天和第二天的评估中，截止点12被认为是最佳的。相对于最低评分日，最佳分界点为10分。结论：Braden量表18分和16分的分界点在不同的临床情境下均显示出较低的预测效度和较低的精确度。(c)2017 Elsevier Espana，S.L.U. y SEMICYUC。All rights reserved.
Objective: Contribution to validation of the Braden scale in patients admitted to the ICU, based on an analysis of its reliability and predictive validity.Design: An analytical, observational, longitudinal prospective study was carried out.Setting: Intensive Care Unit, Hospital Virgen del Rocio, Seville (Spain).Patients: Patients aged 18 years or older and admitted for over 24 hours to the ICU were included. Patients with pressure ulcers upon admission were excluded. A total of 335 patients were enrolled in two study periods of one month each.Interventions: None.Variables of interest: The presence of grade i-iv pressure ulcers was regarded as the main or dependent variable. Three categories were considered (demographic, clinical and prognostic) for the remaining variables.Results: The incidence of patients who developed pressure ulcers was 8.1%. The proportion of grade i and ii pressure ulcer was 40.6% and 59.4% respectively, highlighting the sacrum as the most frequently affected location. Cronbach's alpha coefficient in the assessments considered indicated good to moderate reliability. In the three evaluations made, a cutoff point of 12 was presented as optimal in the assessment of the first and second days of admission. In relation to the assessment of the day with minimum score, the optimal cutoff point was 10.Conclusions: The Braden scale shows insufficient predictive validity and poor precision for cutoff points of both 18 and 16, which are those accepted in the different clinical scenarios.
