A MIXED RESEARCH STUDY ON THE USERS-CENTERED M-HEALTH MOBILE APPLICATION DESIGN, DEVELOPMENT, AND SUS EVALUATION ON UTILITY AND USABILITY FOR SELF-CARE MANAGEMENT OF TYPE-2 DIABETES IN URBAN HOME SETTINGS

Abstract

The m-health application was designed for self-care management of type 2 diabetes and keeping the patient at the core, the application was designed, human-centered focusing on comprehensive self-care management, which included, daily dairy, nutrition, food update, exercise, medicine intake, and nutrition informatics to support for improving self-care management adherence to self-care activities. A mixed research study both qualitative and quantitative exploratory sequential study in an urban population of 18-75years with type-2diabetes patients recruited from urban clinics and those who have access to Android mobile. A Sample of N=275patientswasrecruitedover the telephone, and from health apps, and n=250 was retained in this study. All of them went through self-assessment of Diabetes Based Management System Questionnaires (DBMS)and filled out daily diaries, tracked exercise, food, and nutrition, and were followed up on health applications. The usability and utility of this application were tested and scored using qualitative methods in a sample n=55 using the system usability scale (SUS)global tool and the application was evaluated using 10 points scale of SUS. The study shows overall, the combined improvements in these factors resulted in a substantial 5.1% enhancement in self-care management, highlighting the potential benefits of addressing multiple aspects of Type 2 diabetes self-care management led to an increase in HbA1c improvement by 14.2%of the sample, indicating a positive impact on diabetes management. significant variation (p < 0.0000) with a mean square (MS) of 428.2. The Intercept also showed significant variation (p < 0.0000) with an MS of 5412. The Gender factor had a significant but relatively smaller impact (p = 0.0042, MS = 1250).The final SUS score on the utility and usability of this designed application. X = 5-the total points for all questions with an odd number. The sum of the points for all even-numbered questions equals Y = 25, or 25. SUS Score = 2.5 times (X + Y).X= 16.6 + Y+17.1= 33.7 * 2.5 = 84.25 total score is achieved findings on SUS qualitative assessment, that users find health applications designed useful, easy to use, and helpful for them, therefore utility and usability scores >80 scores in the scale. The Hb1AC improvement reporting had a highly significant effect (p < 0.0000, MS = 64.5).
reporting of the results will is done at 95% CIs and P=.0.05.In n=55 respondents tested with the SUS questionnaire.
