ABSTRACT This 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.

    ABSTRACT: Telenursing includes every nursing and care-giving services conducted remotely. In telenursing, telephone as a device, which is available for most of the people, is being used increasingly. In a telephone-based system, patients are being contacted by health care providers on regular bases and they would be provided with some information about their illness and their treatment method. This study was conducted to determine the effect of phone-based follow-ups on diabetes patients' metabolic control in the city of Kerman in Iran. This is a quasi-experimental study conducted on 50 type II diabetes patients in Kerman during 2011. Data were collected using a demographic questionnaire and also by taking physiological measurement of fasting blood suger (FBS), Glycated Hemoglobin (HbA1c), and postprandial glucose (PPG). Participants' body mass index (BMI) was calculated by measuring height and weight. Patients completed the questionnaire at the beginning of the study and 12 weeks later. The patients were randomly divided into two groups of experiment and control. Patients in the experimental group received phone calls by the researcher for 12 weeks, and the follow-ups included instructions on self-care and advices to follow their diets, exercise, and insulin titration. Data analysis was done using descriptive and inferential statistical methods (chi-square, analysis of variance [ANOVA], independent t-test, and paired t-test). The decrease of HbA1c and PPG was significantly more in the intervention group compared with the controls (P < 0.001). However, there was no significant difference between the mean of FBS (P = 0.42), and BMI (P = 0.31) in both groups after the intervention. According to the results of this study, telenursing was able to improve the metabolic indices of the patients. Therefore, using this method is recommended for patients with type II diabetes.

    ABSTRACT: Telephone-delivered intervention can provide many supports in diabetes self-management to improve glycemic control. Several trials showed that telephone intervention was positively associated with glycemic outcomes in diabetes. The objective of this meta-analysis was to assess the impact of telephone contact intervention (intervention group) on glycemic control compared with standard clinical care (control group). Randomized control studies of telephone intervention in diabetes were searched on Medline (Pubmed), the Cochrane Central Register of Controlled Trials, Cumulative Index to Nursing and Allied Health Literature (CINAHL), Web of Science (ISI), and Scopus. Electronic search was done from inception to April 2013. The following MeSH terms were used: diabetes mellitus, randomized control trials and telemedicine, together with keywords including phone intervention, diabetes, and glycemic control. Historical search was also conducted on the references of relevant articles. The quality of the trials was assessed using Maastricht-Amsterdam scale. Treatment effect was estimated with mean difference in the change of hemoglobin A1c (HbA1c) from baseline between the intervention and control groups. A total of 203 articles were examined. Five trials involving 953 patients met the inclusion criteria and contributed to the meta-analysis. Telephone contact intervention was no more effective than standard clinical care in improving glycemic control (pooled mean difference in HbA1c -0.38%, 95%CI -0.91 to 0.16%). This meta-analysis showed that the phone contact intervention was no more effective than standard clinical care in improving glycemic control in diabetes. However, telephone intervention may still have potential benefits especially for low-and middle-income countries; thus further large sample size and well-controlled studies are needed to evaluate the impact of the intervention.
