Acute leukemia accounts for about 8% of total human cancers and is the fifth most common cancer worldwide (1, 3). Due to the trend of demographic changes and increase in life expectancy in Iran, cancer incidence is predicted to reach from 84,800 in 2012 to 129,700 in 2025, with a 35% increase in the incidence of cancerous people (4). Acute leukemia is commonly treated with chemotherapy and stem cell transplantation (SCT) (7). Unlike other methods, chemotherapy is a systemic technique that results in the incidence of multiple side effects, such as nausea, vomiting, anxiety, depression, and fatigue (8, 9). As one of the treatment methods for acute leukemia, SCT has grown rapidly during the last two decades and reaches about 100,000 cases per year (10, 11).
SCT-related physical side effects include early direct toxicity caused by chemotherapy and radiation therapy, acute graft-versus-host disease (GVHD), infection, pain, frequent re-hospitalization, and many hospitalization days to treat complications. Common mental complications include anger, fear of disease recurrence, post-traumatic stress reactions, cognitive impairment, occupational disability, decreased life satisfaction, reduced adaptability and self-confidence, and elevated emotional tensions (12, 13).
Among the mentioned complications, mucositis is one of the most common complications after chemotherapy and SCT in leukemia patients, causing oral ulcers, severe pain, and the risk of infection in oral ulcers. On the other hand, after improving blood cell count and discharge from hospitals, leukemia patients undergoing SCT may require frequent and long-term hospitalization because of GVHD complications (16%), infection (28%), gastrointestinal complications (18%), and fever without known infection (26%), and therefore prevention of these complications is of paramount importance (8, 14). Polito et al. reported the development of mucositis in about 40% of chemotherapy patients (15).
During hospitalization, the care period, and discharge from hospitals, questions usually arise for these patients about the self-care procedure, such as a proper diet, the allowed activity level, the disease complications, and their monitoring and management procedures. However, the education provided to these patients is limited to the usual education, and they do not receive continuous education in this context (16, 17). Since most patients and their caregivers are responsible for monitoring and managing the side effects of their treatment at home, self-care education is one of their essential requirements (18). Because nurses are actively present in all stages of SCT and patient care, they can play an essential role in self-care education for these patients (19). Face-to-face education in these patients increases the risk of infection transmission, and educational methods should be used that includes minimal communication with patients (20).
A modern educational tool is mobile technology, which provides learners with constant access to learning at home, at work, and on the go, and has eliminated many limitations and inefficiencies (21, 22). Furthermore, the impact of mobile phone applications on the improvement and reduction of cancer-induced complications compared to traditional methods has been established in a plethora of studies (9, 23, 24).
Therefore, there is a need for minimum face-to-face communication with these patients, providing continuous and persistent education, and increasing their self-care ability given the limitations of traditional education methods. Therefore, this study aimed to determine the effect of self-care education with smart phone applications on post-SCT mucositis severity and infection rate in leukemia patients.
