Application of analytical hierarchy process in the cause analysis of displacement of peripherally inserted central catheters among pediatric patients with hematologic disease

Objective To explore the main cause of displacement of peripherally inserted central catheters （ PICC） among pediatric patients with hematologic disease .Methods Eleven nurses and 10 children＇s parents received the questionnaire on the cause analysis of displacement of PICC among pediatric patients with hematological tumor which was made through the analytical hierarchy process theory , the literature review and interview.The weight of each indicator was calculated in the two groups , and the indicator was put in the right order according to their weights .Results The top 4 main causes agreed by nurses and parents in the displacement of PICC among pediatric patients with hematologic disease were respectively poor supervision C 6 , non-standard dressing methods C 1 , different adhesive forces of dressings C 15 , excessive activity of arm in where the PICC line was located C 9 , and the predominant reason was the poor supervision C 6 .Conclusions We should strengthen the training of nurses , and choose the appropriate dressings , and enhance the guard consciousness of the displacement of PICC in children＇s parents , and reinforce the supervision , and reduce the arm activity so as to decrease the displacement of PICC among pediatric patients with hematologic disease .
