The Effect of Gastrointestinal Mucositis Care Training Given to Pediatric Leukemic Patients and Caregivers on Mucosal Barrier Injury.

Background: Management of chemotherapy-induced mucosal barrier damage and oral/anal mucositis in leukemia is challenging.

Objective: The aim of this study was to investigate the effect of mucositis care training given to children receiving leukemia treatment and their caregivers on caregiver knowledge and skills, the development of gastrointestinal mucositis in children, the mean oral mucositis area in children, and the mucosal barrier injury laboratory-confirmed bloodstream infection in the clinic.

Methods: A stepped-wedge, quasi-experimental, unpaired control group design was used. The participants in the control group were given routine training, and the intervention group members were given mucositis care training in accordance with the guideline recommendations.

Results: No significant difference was found between groups in developing anal mucositis, but a significant difference in developing oral mucositis was documented, with the mean mucositis area of children being 8.36 ± 3.97 cm2 in the control group and 4.66 ± 2.90 cm2 in the intervention group. The mucosal barrier injury laboratory-confirmed bloodstream infection ratio was 4 per 1000 catheter days in the control group and 3 per 1000 catheter days in the intervention group.

Conclusion: Mucositis care training had a significant positive effect on caregivers' knowledge and skills, the development of oral mucositis, and the mean oral mucositis area in children. However, the training had no effect on the development of anal mucositis or the infection rate in the clinic.

Implications for practice: Nurses might increase the knowledge and skill levels of caregivers with training on mucositis care, prevent the development of mucositis, and reduce the mean mucositis area. Training might also contribute to the reduction in the infection rate of the clinic.
