A new, synthetic, silk-like fabric was developed for the purpose of providing bedding and patient gowns that manage moisture, friction, and shear when used between the patient and the healthcare support surface that may affect the development of pressure ulcers (PUs). A retrospective study was conducted to compare the incidence of hospital-acquired PUs in patients admitted to Telemetry, Urology, and Intensive Care Units before and after hospital linens were changed from standard to the synthetic (intervention) linens. Patient medical record data were abstracted for a period 12 weeks before (control) and 12 weeks following the linen change (intervention). Patient demographic information, Braden Risk Scale score, and PU status and stage were abstracted for a total of 659 patients in the control and 768 patients in the intervention groups. No significant differences in patient weight, age, gender distribution, PU risk (Braden scale scores), or proportion of PUs on admission between groups were found. The most common comorbidity was hypertension (n = 981, 68.7%). On admission, the percentage of patients with PUs in the control and intervention groups was 9.9% (σ = 0.3) and 8.7% (σ = 0.3), respectively (P = 0.23). Average length of stay was 5.6 days in the control and 5.2 days in the intervention groups (P = 0.08). Sixty-eight (68) of 659 patients (10.3%) in the control and 19 out of 768 patients in the intervention group (2.5%) developed one or more PUs (P <0.001) for an incidence of 11.5% in the control and 3.1% in the intervention group. At discharge, 136 PUs were present in the control and 64 were present in the intervention group (P <0.001). The significant differences in the incidence of hospital-acquired PUs between the two groups suggest that linen type affects PU risk. Additional controlled clinical studies in high-risk patient populations are warranted.
为了提供床单和病人服，研发了一种新型合成丝织物，当它用于病人与医疗支撑面之间时，能够控制湿度、摩擦力和剪切力，而这些因素可能会影响压疮（PU）的形成。开展了一项回顾性研究，比较在医院床单从标准床单更换为合成（干预）床单前后，入住遥测病房、泌尿外科病房和重症监护病房的患者中，医院获得性压疮的发生率。提取了患者病历数据，包括更换床单前12周（对照）和更换床单后12周（干预）的数据。共提取了对照组659名患者和干预组768名患者的人口统计学信息、Braden风险量表评分以及压疮状态和分期。两组患者在体重、年龄、性别分布、压疮风险（Braden量表评分）或入院时压疮比例方面均未发现显著差异。最常见的合并症是高血压（n = 981，68.7%）。入院时，对照组和干预组有压疮的患者百分比分别为9.9%（σ = 0.3）和8.7%（σ = 0.3）（P = 0.23）。对照组的平均住院时间为5.6天，干预组为5.2天（P = 0.08）。对照组659名患者中有68名（10.3%），干预组768名患者中有19名（2.5%）发生了一个或多个压疮（P <0.001），对照组的发生率为11.5%，干预组为3.1%。出院时，对照组有136个压疮，干预组有64个压疮（P <0.001）。两组医院获得性压疮发生率的显著差异表明床单类型会影响压疮风险。有必要在高危患者群体中开展更多对照临床研究。
