    (Sri Lanka Medical Association, 2018) Dhanishka, L.; Gunawardena, K.C.; Jackson, R.; Jayamanne, S. F.; Kalpani, A. G. S.; Muthukuda, D. T.; Robinett, I.
    INTRODUCTION AND OBJECTIVES: Smartphone use is growing rapidly in developing countries and mobile plications have begun to be utilized in the field of diabetes. Present study was conducted to evaluate the effectiveness of a newer mobile application, Smart Glucose Manager (SGM) in the management of diabetes mellitus. _ METHODS: A prospective randomized control trial was conducted at out-patient diabetes clinics of Sri Jayewardenepura General Hospital. Patients with HbAlc = 8.0% with access to smart phone were recruited and randomly assigned to two arms. Patients in both arms received standard care, the intervention arm received the mobile application, SGM. HbAlc levels were measured at baseline and every 3-months. RESULTS: The mean age of the study participants was 52±11 years. The improvement of mean HbAlc from baseline to 3-months follow-up, the intervention (baseline: 9.7%±1.3, follow-up: 8.2%±1.0, p =0.001) and control (baseline: 9.5%±1.6, follow-up: 8.2%±0.6, p=0.008) arms were not significantly different (p=0.98). However, a significant improvement in HbAlc was observed in the intervention arm from 3-months (8.3%±0.6) to 6-months (7.3%+_0.6), (p=0.005) compared with the control arm (8.2% at 3-months) (7.9%+_0.6-months), (p=0.16). Improvement of mean HbA1c was shown in both arms 3- months after the baseline clinic visit, but after 6-months, only the intervention arm continued to show statistically significant improvement of HbAlc(p=0.01). CONCLUSION: The improved glycemic control after 6 months in the intervention arm patients suggests increased patients compliance via the unique features of SGM. Further studies should be carried out to assess the long-term impact of SGM in diabetes patients.

    The Influence of the smart glucose manager mobile application on Diabetes management
    (Sage Publications, 2019) Gunawardena, K.C.; Jackson, R.; Robinett, I.; Dhaniska, L.; Jayamanne, S.; Kalpani, S.; Muthukuda, D.
    BACKGROUND: Smartphone use is rapidly growing in developing countries, providing opportunity for development of new health-based mobile applications. The present study investigated the efficacy of a newly designed mobile application, Smart Glucose Manager (SGM), in Sri Lankan patients with diabetes. METHODS: A total of 67 patients with access to Android smartphones were randomized into an SGM (n = 27) and a control group (n = 25). Glycosylated hemoglobin (A1c) levels were measured at baseline and every 3 months afterward. The SGM group utilized the application daily, while control-group patients were instructed to continue their standard methods of diabetes management. Independent t-tests were utilized to assess A1c differences at 3 and 6 months postrandomization. A1c improvement, defined as A1c at 6 months minus baseline, was compared with SGM usage to assess effectiveness of diabetic management. RESULTS: At the 6-month follow up, the SGM group had significant lower A1c levels than the control group (7.2% vs 8.17%, P < .0001). For both groups, A1c values decreased from baseline to the 3 months (SGM: 9.52% to 8.16%, P < .0001; control: 9.44% to 8.31%, P < .0001). From 3 months to 6 months, the SGM group showed further improvement of A1c (-0.96% P < .0001), whereas the control group did not ( P = 0.19). A1c improvement was positively correlated with SGM usage ( R = .81, P < .001). CONCLUSION: The SGM, a mobile application specifically designed to support self-management of diabetes, appeared to show long-term improvement of A1c levels in patients with diabetes residing in Sri Lanka.
