The influential factors and intervention strategies that engage malignant cancer patients in health-promoting behaviors during PICC line maintenance.

OBJECTIVE To analyze the influential factors and intervention strategies involved in engaging health-promoting behaviors (EHPD) during peripheral central venous catheter (PICC) line maintenance in malignant tumor patients. METHODS 120 patients with malignant tumors who underwent PICC line maintenance in our hospital were prospectively analyzed. They were divided into a low and moderate level group (HPLP-II score ≤137) and a high level group (HPLP-II score >137) according to their Health Promoting Lifestyle Profile II (HPLP-II) questionnaire scores. Single-factor and multifactor analyses were performed to identify the factors influencing the patients' engagement in self-health-promoting behaviors. The one hundred and twenty patients with malignant tumors were randomly divided into two groups (n=60 in each group). The control group and the intervention group underwent routine nursing care and patient education. The two groups were compared in terms of the changes in their HPLP-II scores, their Cancer Patients PICC Self-management Scale (CPPSM) scores, their SAS and their SDS scores before and after the intervention, as well as their maintenance compliance rates, their complication rates during catheter placement, and their lack of PICC maintenance. RESULTS Literacy, place of residence, duration of catheter use, self-management abilities of PICCs, social support, and anxiety were risk factors (OR>1, P<0.05). Compared with their pre-intervention scores, the HPLP-II and CPPSM scores were increased in both groups (P<0.05), and the SAS and SDS scores were decreased in both groups after the intervention (P<0.05), and the intervention group had higher scores than the control group (P<0.05). The intervention group exhibited a higher maintenance compliance rate than the control group (P<0.05). The incidence of complications and the lack of PICC maintenance in the intervention group were lower than they were in the control group (P<0.05). CONCLUSION The influential factors during PICC maintenance for EHPD in malignant cancer patients include literacy, place of residence, duration of PICC use, etc. Patient education can promote patients' EHPD and self-management abilities, relieve their anxiety and depression, reduce their complications, and improve their compliance.
