PPAL评估
PPAL床边便桶的开发与评估:实现安全独立的如厕转移
本研究旨在更好地了解PPAL辅助如厕设备的影响。 PPAL包含一个带集成转移板的电动可升降便椅。 该系统设计使用户能够在护理人员提供极少手动帮助的情况下,自行完成从床或椅子到PPAL的如厕转移。 需要转移辅助的用户及其护理人员在转移过程中有很大可能遭受伤害。
本研究目的是在家庭环境中评估PPAL床边便椅,通过为期6周的家庭试验更好地了解该设备的影响。 参与者需与研究团队预约家访,研究人员将筛查其家居环境,询问问题并观察参与者当前如厕/使用便椅的转移方式,以确保他们和护理人员适合使用该设备。 通过审核后,将安排送货日期将PPAL送至参与者家中。 在6周试验结束时,研究团队将安排最终研究访问日期,收回PPAL设备,并再次询问问题及观察使用PPAL和常规便椅的如厕转移过程。 最后,研究人员将访谈参与者及其护理人员,了解他们对设备的满意度。 此次访谈将进行录音。
本研究涉及的风险极小且预计很少发生。 由于参与者将使用不熟悉的设备,可能存在擦伤、淤青、割伤或夹伤的风险。 此外,参与者在尝试转移至设备或从设备移开时可能存在跌倒风险,但研究人员将全面演示设备用法并监督使用过程以最大限度降低此风险。 存在保密信息泄露风险,因为短信和邮件在传输或存储过程中可能未加密或不安全,有可能被与本研究无关的第三方截获使用。
参与本研究对参与者没有直接获益,但将帮助PPAL开发者更好地了解潜在使用者(护理人员和患者)的意见、需求和能力。

武器和干预
参与者组/臂 |
干预/治疗 |
|---|---|
|
实验性的:PPAL 用户
|
PPAL是一款获得专利的电动可调高度床边便椅,配有集成转移板。
PPAL配备的转移板可随椅座升降而上下移动,确保用户始终能进行下坡式转移。
此项创新将使目前依赖护理人员协助转移的行动受限人士能够更独立地完成转移。

|---|---|---|
|
与如厕相关的跌倒效能变化
大体时间:试验前至6周试验后变化
|
我们旨在确定使用PPAL是否能减少如厕活动期间对跌倒的恐惧。
为此,我们将采用轮椅和代步车使用者跌倒顾虑量表(FCS-WC/S)进行评估。
各项条目按顾虑程度评分,1分表示“完全不担心”,4分表示“非常担心”。
得分可从具体问题或整体问卷进行分析。
本次结果我们将重点关注与在家中使用马桶或便椅起坐相关的具体条目。
研究结束时FCS-WC/S评分的降低将表明对跌倒恐惧的减轻。

GG自理评分中如厕转移的变化
大体时间:试验前后6周的变化
|
我们旨在观察如厕转移GG自理评分的变化,具体体现为个体安全上下马桶或便椅能力的改善。
该项目按1分(依赖:完全需要照护者协助)至6分(独立:无需任何帮助)的等级评分。
该评分增加将表明功能独立性的提升。
|
试验前后6周的变化
|
|
系统可用性量表 (SUS)
大体时间:在为期6周的试验结束时
|
我们的目标是验证试验结束时PPAL至少能达到可接受的可用性水平。
SUS量表包含采用1分(非常不同意)至5分(非常同意)评分标准的项目,用于评估参与者在多个领域对系统可用性的感知。
通过计算总分(分值范围0-100,分数越高表示可用性越好),得分达到68分及以上即表明具有可接受的可用性。
