RESUMO
Patients undergoing allogeneic hematopoietic stem cell transplantation (HSCT) procedures often experience high levels of uncertainty. In this study, we developed and implemented a nursing intervention program to help patients recognize and reduce pre-transplant uncertainty. This study used a pretest-posttest single-group design without a control group. Eighteen patients undergoing HSCT participated in the intervention program-which included informational support, confirmation that the patients understood the information provided, and emotional support. Outpatients received the intervention at their initial outpatient visits after their procedure dates were determined, while inpatients received it at discharge following their procedures. The Universal Uncertainty in Illness Scale (UUIS), which consists of 26 items and six subscales, was used as the primary outcome measure. The European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30) and the Hospital Anxiety and Depression Scale were used as secondary outcome measures. The sample included 18 individuals (13 male and five female participants; median age, 52 years). Most participants had acute lymphoblastic leukemia and had previously undergone bone marrow transplantations. Following our intervention, the total UUIS score significantly decreased, from 80.83 ± 18.42 before the intervention to 63.06 ± 23.53 afterward (t = 4.98, p < .001). Furthermore, significant post-intervention reductions were observed for all six subscales of the UUIS. There were no significant differences in the functional EORTC QLQ-C30 scale scores; however, the symptom scale showed a significant decrease in fatigue (pre = 35.19 ± 19.53, post = 25.93 ± 17.04, Z = -1.99, p < 0.046) and constipation (pre = 20.37 ± 20.26, post = 7.41 ± 14.26, Z = -2.11, p = 0.035). There were no significant differences in anxiety and depression levels pre- and post-intervention. Overall, the intervention effectively reduced both UUIS total and subscale scores related to pre-HSCT uncertainties. Assessing uncertainty prior to HSCT is vital to assisting patients in coping with the procedure. Nurses not only provide information but also tailor the information to the patients' cognitive abilities, thereby simplifying their understanding of the disease and its treatment.
