Contribution to validation of the Braden scale in patients admitted to the ICU, based on an analysis of its reliability and predictive validity.
An analytical, observational, longitudinal prospective study was carried out.
Intensive Care Unit, Hospital Virgen del Rocío, Seville (Spain).
Patients aged 18years or older and admitted for over 24hours 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.
None.
The presence of gradei-iv pressure ulcers was regarded as the main or dependent variable. Three categories were considered (demographic, clinical and prognostic) for the remaining variables.
The incidence of patients who developed pressure ulcers was 8.1%. The proportion of gradei andii 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.
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.
基于对Braden量表可靠性和预测效度的分析，为其在重症监护病房（ICU）患者中的验证提供参考。
开展一项分析性、观察性、纵向前瞻性研究。
西班牙塞维利亚罗西奥圣母医院重症监护病房。
纳入年龄在18岁及以上、入住ICU超过24小时的患者。入院时患有压疮的患者被排除。在两个为期一个月的研究阶段共纳入335例患者。
无。
I-IV级压疮的存在被视为主要或因变量。其余变量分为三类（人口统计学、临床和预后）。
发生压疮的患者发生率为8.1%。I级和II级压疮的比例分别为40.6%和59.4%，其中骶骨是最常受累部位。所考虑评估中的Cronbach's alpha系数显示出良好至中等的可靠性。在进行的三次评估中，入院第一天和第二天的评估中，最佳临界值为12。关于最低分日的评估，最佳临界值为10。
Braden量表对于18和16这两个在不同临床场景中被认可的临界值，显示出不足的预测效度和较差的精度。
