Aim The present study aimed to develop a self‐management application for patients with gout and determine the clinical feasibility of the application. Methods A self‐management application (GoutCare) was developed from July 1, 2016, to October 30, 2016, by reflecting on the key elements of Fisher & Fisher's information‐motivation‐behavioral skills model. In order to determine the clinical feasibility of the application, a non‐equivalent, control group, pre‐test‐posttest study was conducted among patients with gout who visited a university hospital from January to April 2017. Twenty‐seven subjects in the experimental group used the smartphone allocation for 8 weeks, and 29 subjects in the control group were provided a leaflet with information on gout self‐management. Knowledge of gout, self‐management attitude, perceived social support, self‐efficacy, self‐management performance, and health‐related quality of life before and after the intervention were measured using a structured questionnaire. Results The self‐management application (GoutCare) developed for patients with gout was found to be effective in improving the knowledge of gout, self‐management attitude, perceived social support, self‐efficacy, self‐management performance, and physical health‐related quality of life. Conclusion In conclusion, the application contributed to improving the self‐management performance and health‐related quality of life in the patients with gout. Therefore, this application can be used as a nursing intervention program for promoting self‐management in patients with gout.
