Outline of Final Research Achievements

This study aimed to classify the system using quantification theory III for the catheter fixing method to prevent unplanned extubation, test the peel strength of surgical tape and dressing, and make environmental adjustments to prevent accidental extubation. The fixing method converges on two axes (axes related to fixing strength and fixing complexity) and three groups. For tapes and dressing materials, a notch of 50% of the major axis provides fixing strength. For maximum security, if a drip and portable toilet are installed on the left side of the patient, a portable toilet must be installed at the feet or side. When the patient moves from the bed to the portable toilet, look at the head side of the bed and rotate. This technique could be used in clinical practice.

Academic Significance and Societal Importance of the Research Achievements

計画外抜去予防のために、医療現場では看護師が中心となり抑制具の試作や使用、カテーテル固定の改善などの様々な対策に取り組んでいる。一方で、カテーテル固定は各病院や施設で固定方法が異なる現状である。本研究の結果から、患者の状況の応じた点滴固定の必要性、テープの切れ込みの重要性、病床環境の調整による事故抜去の低減について明らかにすることができたことから、学術的意義および社会的意義がある。
