Use of a Smartphone Medical App Improves Complications and Quality of Life in Patients with Nasopharyngeal Carcinoma Who Underwent Radiotherapy and Chemotherapy.

BACKGROUND We explored the intervention effect of a smartphone medical app on complications and quality of life of patients with nasopharyngeal carcinoma who underwent radiotherapy and chemotherapy. MATERIAL AND METHODS We divided 132 patients with nasopharyngeal carcinoma who received radiotherapy and chemotherapy for the first time, in accordance with the random number table method, into a control group (67 patients) and an intervention group (65 patients). Patients in control group were discharged with standard care and patients in the intervention group used a smartphone medical app after discharge. Data on adverse effects of radiotherapy and chemotherapy, complications, and quality of life were collected and analyzed. RESULTS There was no difference between the complications of radiotherapy and chemotherapy and quality of life between the 2 groups at discharge (P>0.05). The incidence of oral mucositis, xerostomia, mouth-opening difficulties, and nasal congestion in the intervention group was significantly lower than in the control group at 6 months after discharge and quality of life was significantly higher than in the control group (P<0.05). CONCLUSIONS Reasonable use of this smartphone app can improve the exercise compliance of discharged patients with nasopharyngeal carcinoma who underwent radiotherapy and chemotherapy, reduce the adverse reactions and complications of radiotherapy and chemotherapy, and improve quality of life and satisfaction of patients after discharge.
