Hand hygiene: knowledge and skill of caregivers in the hematopoietic stem cell transplantation

ABSTRACT Objective: to identify the knowledge and ability of caregivers on hand hygiene in hematopoietic stem cell transplantation. Method: a prospective cross-sectional study. A questionnaire was used to identify the knowledge and it was observed the hygiene technique performance. Data were collected in two units (autologous and allogeneic transplant). Results: the 37 participants recognized the importance of hand hygiene and 95.5% related to removal of dirt or infection prevention. 91.9% stated that it was important to clean their hands with soap and water when entering and leaving the room, and 64.9% understood that it was necessary to apply alcoholic solution after washing. On average, the caregivers scored 6.16 steps, when demonstrating the washing technique and 3.91 steps in the friction with alcoholic solution. Conclusion: although they recognize the importance of the procedure, there are deficits related to the moment and the correct way of doing it, evidencing the need for strategies aimed at improving this process.

摘要
目的：明确造血干细胞移植（hematopoietic stem cell transplantation）照护者的手卫生（hand hygiene）知识与操作能力。
方法：本研究为前瞻性横断面研究，采用问卷调查法评估照护者的手卫生知识，并通过现场观察其手卫生操作执行情况。数据采集于自体移植（autologous transplant）与异基因移植（allogeneic transplant）两个单元。
结果：本次纳入的37名研究对象均认可手卫生的重要性，其中95.5%的受访者知晓手卫生可去除污垢或预防感染。91.9%的受访者认为进出病房时使用肥皂和清水清洁手部十分必要，64.9%的研究对象了解洗手后需使用酒精溶液（alcoholic solution）进行手部消毒。在操作演示中，照护者的洗手步骤平均完成6.16项，使用酒精溶液进行手部摩擦消毒的步骤平均完成3.91项。
结论：尽管照护者均认可手卫生操作的重要性，但在手卫生时机把握与正确操作流程方面仍存在不足，提示需制定针对性策略以优化该环节的实践质量。
