- ItemDevelopment of web-based diabetic patient management system using short message service (SMS).(2004-11-26) Kwon, Hyuk-Sang; Cho, Jae-Hyoung; Kim, Hee-Soo; Lee, Jin-Hee; Song, Bok-Re; Oh, Jung-Ah; Han, Je-Ho; Kim, Hee-Seung; Cha, Bong-Yun; Lee, Kwang-Woo; Son, Ho-Young; Kang, Sung-Koo; Lee, Won-Chul; Yoon, Kun-HoWe developed a blood glucose management system using the Internet and short message service SMS which can lessen the social economic burden and materialize an individualized diabetes mellitus management A total of 185 diabetic patients participated in this study and their mean age was 42 4 years old 8 79 year old Participants sent their self measured blood glucose levels medication and its dosages amount of meal and degree of exercise to their health providers in this specialized web based diabetes management system for 3 months The health providers consisting of endocrinology specialists dietitians and nurses sent recommendations for individualized diabetes management according to the data on the web Laboratory tests including lipid profiles and glycated hemoglobin HbA1c and a survey of satisfaction about this system were performed before and after the study period The mean HbA1c improved from 7 5 1 5 to 7 0 1 1 after using the management program P 0 003 The mean serum triglyceride and HDL cholesterol levels turned for the better also HbA1c improved from 8 4 1 2 to 7 5 1 0 after applying this program to patients with the HbA1c of 7 or higher at baseline P 0 010 We propose this web based diabetic patient management system as a new tool for communication between health care providers and patients
- ItemExploring the relationship among user satisfaction, compliance, and clinical outcomes of telemedicine services for glucose control.(2014-07-25) Rho, Mi Jung; Kim, Si Ra; Kim, Hun-Sung; Cho, Jae-Hyoung; Yoon, Kun-Ho; Mun, Seong K; Choi, In YoungAlthough research has shown that telemedicine services for blood glucose control can be useful in managing diabetes the relationships among user satisfaction compliance and clinical outcomes have not been well studied A positive assessment of telemedicine services can improve user satisfaction which can increase compliance and improve clinical outcomes These relationships are validated with actual telemedicine projects for diabetes management
- ItemMobile communication using a mobile phone with a glucometer for glucose control in Type 2 patients with diabetes: as effective as an Internet-based glucose monitoring system.(2009-02-27) Cho, Jae-Hyoung; Lee, Hye-Chung; Lim, Dong-Jun; Kwon, Hyuk-Sang; Yoon, Kun-HoA mobile phone with a glucometer integrated into the battery pack the Diabetes Phone was launched in Korea in 2003 We compared its effect on management of type 2 diabetes to the Internet based glucose monitoring system IBGMS which had been studied previously We conducted a randomized trial involving 69 patients for three months Participants were assigned to an Internet group or a phone group The phone group communicated with medical staff through the mobile phone only Their glucose monitoring data were automatically transferred to individual web based charts and they received medical recommendations by short message service The Internet group used the IBGMS There were no significant differences between the groups at baseline After three months intervention HbA 1c levels of both groups had decreased significantly from 7 6 to 6 9 for the Internet group and from 8 3 to 7 1 for the phone group P Under 0 01 Levels of patient satisfaction and adherence to medical advice were similar Mobile bidirectional communication between doctors and patients using the diabetes phone was as effective for glucose control as the previously studied Internet based monitoring system and it was good for patient satisfaction and adherence
- ItemService design attributes affecting diabetic patient preferences of telemedicine in South Korea.(2011-07-19) Park, Hayoung; Chon, Yucheong; Lee, Jongsu; Choi, Ie-Jung; Yoon, Kun-HoOBJECTIVE Attempts to introduce telemedicine in South Korea have failed mostly leaving critical questions for service developers and providers about whether patients would be willing to pay for the service and how the service should be designed to encourage patient buy in In this study we explore patients valuations and preferences for each attribute of telemedicine service for diabetes management and evaluate patient willingness to pay for specific service attributes MATERIALS AND METHODS We conducted a conjoint survey to collect data on patients stated preferences among telemedicine service alternatives The alternatives for diabetes related service differed in 10 attributes including those related to price type of service provider and service scope To estimate the relative importance of attributes patients willingness to pay for each attribute and their probable choice of specific alternatives we used a rank ordered logit model A total of 118 respondents participated in the survey RESULTS All 10 attributes significantly affected patients valuations and preferences and demographic and disease characteristics such as existence of complications and comorbidities significantly affected patients valuations of the attributes Price was the most important attribute followed by comprehensive scope of service the availability of mobile phone based delivery and large general hospital provided services CONCLUSIONS The study findings have significant implications for adoption policy and strategy of telemedicine in diabetes management care Further the methodology presented in this study can be used to draw knowledge needed to formulate effective policy for adoption of the necessary technology and for the design of services that attract potential beneficiaries
- ItemA short message service by cellular phone in type 2 diabetic patients for 12 months.(2008-02-01) Yoon, Kun-Ho; Kim, Hee-SeungOBJECTIVE Investigate the effectiveness of an educational intervention that used both the cellular phone with a short messaging service SMS and the Internet on the glycemic control of the patients with type 2 diabetes mellitus METHODS Twenty five patients were randomly assigned to an intervention group and twenty six to a control group The intervention was applied for 12 months The goal of the intervention was to keep blood glucose concentrations close to the normal range HbA 1 cUnder7 Patients in the intervention group were asked to access a website by using a cellular phone or to wiring the Internet and input their blood glucose levels weekly Participants were sent the optimal recommendations by both cellular phone and the Internet weekly RESULTS Participants in the intervention group had lower HbA 1 c over 12 months when compared with the control group At 12 months the change from baseline in HbA 1 c was 1 32 in the intervention group versus 0 81 in the control group Two hours post meal glucose 2HPMG had a significantly greater decline in the intervention group after 12 months when compared with the control group 100 0 versus 18 1mg dl CONCLUSION This educational intervention using the Internet and a SMS by cellular phone rapidly improved and stably maintained the glycemic control of the patients with type 2 diabetes mellitus
- ItemA telephone-delivered intervention to improve glycemic control in type 2 diabetic patients.(2003-03-05) Oh, Jeong-Ah; Kim, Hee-Seung; Yoon, Kun-Ho; Choi, Euy-SoonThis study was performed to investigate the effect of a telephone delivered intervention on glycemic control and body mass index in Korean type 2 diabetic patients 38 patients were randomly selected with 20 assigned to a telephone group and 18 to a control group The goal of the intervention was to keep blood glucose concentrations close to the normal range The intervention was applied to the telephone group for 12 weeks It consisted of continuous education and reinforcement of diet exercise and medication adjustment as well as frequent self monitoring of blood glucose levels Telephone intervention was performed twice per week for the first month and then weekly for the second and third months Subjects were requested to write self management logs including blood glucose diet and an exercise diary The diet diaries were analyzed by a dietitian and subjects instructed about the results by telephone counseling or mail All medication adjustments were communicated to the subjects diabetes specialist Glycosylated hemoglobin HbA1c fasting blood glucose FBG and 2 hour postprandial glucose were measured before and after the intervention Patients in the telephone group had a mean decrease of 1 2 with those in the control group having a mean increase of 0 6 in HbA1c There were no significant differences in the body mass index BMI between the two groups These findings indicated that a telephone delivered intervention would improve HbA1c but would not affect BMI
