Purpose
Continuous Glucose Monitoring (CGM) plays a crucial role in helping patients with diabetes manage their blood sugar levels. This review aimed to understand the context and scope of CGM-related studies in Korea and identified areas for future research, particularly in nursing science.
Methods
The search strategy involved examining eight electronic databases for published studies on CGM, with the search period ending in March 2022. Four independent reviewers conducted screening, selection, and narrative review of the studies.
Results
Descriptive and substantive analyses were performed for 68 studies on CGM, which covered diverse areas, including: (1) evaluating the CGM performance through comparisons with self-monitoring of blood glucose and correlations with existing indices; (2) validating the efficacy of CGM in improving patient outcomes and assessing various interventions; and (3) expanding the use of CGM, such as clinical guidelines and reviews, developing predictive models, and other clinical studies.
Conclusion
Research on CGM has expanded to include early performance evaluation, efficacy verification, and utilization in various clinical settings. However, there is a lack of nursing-focused studies of CGM. It is recommended to incorporate CGM in nursing research aimed at enhancing self-management for patients with diabetes. Future projects should focus on developing and applying patient-customized CGM user manuals, comparing the effectiveness of CGM among patients with different types of diabetes, exploring qualitative experiences of CGM use, and addressing related issues.

PURPOSE
This study was conducted to examine factors influencing glycemic control among type 2 Diabetes Mellitus (T2DM) patients using data from the sixth Korea National Health and Nutrition Examination Survey (2013~2015).
METHODS
The subjects were 1,181 patients aged 30 years and older who were diagnosed with T2DM. The subjects were divided into three groups according to the glycated hemoglobin (HbA1c) values: good Glycemic Control Group (good GCT, HbA1c<7%), insufficient GCT (7≤HbA1c <8%), and poor GCT (8%≥HbA1c). Multivariate multinomial logistic regression was used to examine the association of socio-demographic, diabetes-related, health status, weight control, health behavior, and psychological factors with glycemic control among T2DM patients.
RESULTS
The patients were distributed as follows: 44.1% in the good GCT, 29.1% in the insufficient GCT, and 26.8% in the poor GCT. In the insufficient GCT, DM duration, DM treatment, weight change, and smoking were significant factors influencing glycemic control with T2DM. In the poor GCT, age, DM duration, DM treatment, and hypertension were significant factors influencing glycemic control with T2DM.
CONCLUSION
Strategies for the insufficient GCT should include intensive glucose control interventions for patients with DM for over 1 year, combined therapy of oral hypoglycemic agents and insulin. In addition, it is necessary to actively perform nursing interventions for weight loss. Strategies for the poor GCT should include intensive glucose control interventions for younger age groups, more than 5 years of DM, combined therapy of oral hypoglycemic agents and insulin, and those without hypertension.

PURPOSE
The aim of this study was to identify the effect of dextrose intravenous fluid (IVF) on the blood glucose levels taken from both fingertips of patients with diabetes mellitus (DM) and those without DM.
METHODS
From October 2012 to February 2013, 21 DM and 25 non-DM patients were recruited. Blood glucose levels taken from the both fingertips of patients at 7AM while IVF was not infusing and at 11AM, 5PM, and 9PM while IVF was infusing.
RESULTS
The differences between the mean values of blood glucose from the fingertips at four different times was not statistically significant in DM patients as well as non-DM patients. Also intra-class correlation for blood glucose levels from the fingertips with and without IVF infusion in both groups was shown over about 0.95 at each time (p<.001).
CONCLUSION
Blood glucose levels measured in the same fingertips of both arms were the same regardless of dextrose IVF infusion. The results indicated that IVF with dextrose may not have any significant effect on the fingertip results of blood glucose level. This study may suggest that patients' both arms and any fingertips can be used for blood glucose monitoring even when the patients are on dextrose IVF infusion.

PURPOSE
The purpose of this study was to examine relationships among blood glucose, HbA1c, and self management comparing these with general and illness characteristics of subjects with Type II Diabetes living in the community.
METHODS
Using a comprehensive survey developed for the study, data were collected from 82 type II diabetes patients who were registered at five community health departments. The variables of self management, blood glucose and HbA1c were assessed by nurses. Data were analyzed with descriptive statistics including t-test, ANOVA and Pearson's correlation coefficient to compare self management and level of HbA1c by subject's general and illness characteristics and to examine the relationships among variables.
RESULTS
About 73.2% of the subjects' HbA1c were 7.0% or higher and 54.9% of subjects' blood glucose were 200 mg/dL or higher. The level of self management was moderate. Most frequently perceived reasons for failure of blood glucose control were dietary failure (32.9%). There was significant relationship between self management and HbA1c(r=-.223, p=.040). The mean score of self management were higher among female (t=-2.37, p=.021), who are not on diabetes medication (t=6.70, p=.011).
CONCLUSION
Comprehensive intervention is needed to improve dietary self management, especially for male and those who is on diabetes medication.

PURPOSE
The purpose of this study was to examine the effects of a cognitive behavioral stress management program on diabetic self-care and glycemic control with type 2 diabetic patients.
METHODS
Thirty three diabetic patients who were older than 40 were recruited from a public health center and conveniently assigned into both experimental(n=16) and control groups(n=17). Participants in the experimental group had attended the weekly cognitive behavioral program for 8 weeks. Data were collected from June 2005 to August 2006 and analyzed by independent t-test using the SPSS WIN program.
RESULTS
After an 8 week intervention, participants in the experimental group reported on increasement of diabetic self-care behaviors and an increasement of blood glucose levels, which were significantly different from those in the control group.
CONCLUSION
On the basis of those findings, we concluded that the cognitive behavioral stress management program has positive effects on diabetic self-care and glycemic control for the patients with DM. Further research is needed to identify the long-term effects of the cognitive behavioral program.

PURPOSE
The purpose of this study was to evaluate the effect of antioxidant vitamins and magnesium supplementation on fasting blood glucose and lipids in patients with type 2 diabetes.
METHODS
This study is a unequivalent control group pretest-posttest design. Seventy-one subjects with type 2 diabetes who were recruited from home visiting clients of a public health center, completed the trial. The experimental group entered a 12-week treatment period with antioxidant vitamins and magnesium and the control group with no antioxidant vitamins and magnesium.
RESULTS
Serum level of fasting blood glucose decreased from 134.7 mg/dl to 125.0 mg/dl and total-cholesterol decreased from 215.5 mg/dl to 198.2 mg/dl in the experimental group. No changes in fasting blood glucose and total-cholesterol were demonstrated in the control group.
CONCLUSIONS
A short-term supplementation with antioxidant vitamins and magnesium can reduce fasting blood glucose and total-cholesterol in patients with type 2 diabetes. The continuous effect of this supplementation and the beneficial effect on the prevention of diabetes complication still needs to be demonstrated.

PURPOSE
The purpose of this study was to investigate differences between a pulmonary aspiration group and a non-pulmonary aspiration group in glucose concentration of tracheal secretions by measuring time and feeding methods.
METHOD
The subjects were 36 ICU patients who were receiving formula via nasogastric tubes and had endotracheal tubes or tracheostomy tubes. Tracheal secretions were collected by connecting suction traps to a suction catheter in three different times(within 1 hour after feeding, between 1 to 2 hours after feeding, and between 2 to 3 hours after feeding) for 2 days, overall six times. Glucose concentration of tracheal secretions was measured with the glucometer(Accucheck II).
RESULTS
Glucose concentration of tracheal secretions increased in progression after feeding. The mean of specimens collected last(between two to three hours after feeding) was shown to be the highest value(M= 61.61 mg/dl) in the pulmonary aspiration group. Significantly(p=.000) more subjects(94.44%) in the pulmonary aspiration group received formula via a 50cc syringe than those in the non-pulmonary aspiration group(22.22%).
CONCLUSION
Critically ill patients may need more time for head-elevation after tube feeding to prevent pulmonary aspiration. In practice, enteral formula should not be given the patients via a 50cc syringe anymore, instead a feeding bag or infusion pump should be used to prevent pulmonary aspiration.

PURPOSE
This study was attempted to estimate the effects of diabetic education fortified with individual practice on plasma glucose, self-care, and self reported physical symptoms in type 2 diabetes patients METHOD: The subjects consisted of 46 patients with type 2 diabetes patients, who took the hospitalization diabetes education program from July 2003 until February 2004 at Seoul C university hospital. The experimental group was assessed at pre- and post intervention. The diabetes education was provided for one week. The education consisted of diabetes education videos for the diabetic introduction, group education for medication therapy, dietetic treatment and diabetes complication education. Also individual education for nurses examination of glycemia and insulin injection practice.
RESULTS
The HbA1c values significantly decreased from 9.6% on the time of hospitalization to 7.4% 3 months after discharge. In respect to the number of days of self-care, medication, diet, exercise, cleansing feet, and carrying sweets to prepare for hypoglycemia all significantly increased 3 months after discharge compared to the values at the time of hospitalization. Self reported physical symptoms were also significantly increased 3 months after discharge compared to the time of hospitalization.
CONCLUSION
The diabetic education fortified with individual practice can be practically used as a plan for managing glycemia, self-care, and self reported physical symptom of diabetes patients.

PURPOSE
The purpose of this study was to evaluate whether the effect of the Internet diabetic education on plasma glucose in people with hyperglycemic diabetes. METHOD: A randomized design with control and experimental groups being assessed pre- and post-intervention was used. Twenty-two patients were randomly assigned to an intervention group and 21 to a control group. Participants were requested to input the blood glucose level weekly in http://www.biodang.com by cellular phone or wire Internet for 3 months. The researcher sends optimal recommendations to each patient using short message service(SMS) of cellular phone and wire Internet weekly. RESULTS: Patients in the intervention group had a mean decrease of 1.3% in glycosylated haemoglobin (HbA1c) levels and those in the control group had no significant difference. There was a significant mean change in 2-hour postprandial blood glucose(2HPPG) for the intervention group, with a mean change of -75.2mg/dl. The mean change in the control group was, however, not significant. CONCLUSION: These findings indicated that a web-based intervention using SMS of cellular phone improved HbA1c and 2HPPG.

PUPPOSE: The purpose of this study is to determine the level of pain related to a blood sugar test. Specifically, the study attempts to compare the varying degree of pains when different types of blood sugar test are used.
METHOD
A sample of 56 subjects is composed of DM patients admitted to a medical ward of C university hospital in Gwangju. Data were collected from July, 2001 to December, 2001. The blood sugar tests were administered in four different ways: (1) the use of 27G needle only, (2) the use of 27G needle followed by ice-packed treatment, (3) the use of 27G needle after EMLA cream application, and (4) the use of lancet. The degree of pain is measured with a visual analogue scale and performed twice.
RESULT
In both measures, the use of 27G needle only method is shown to cause the highest level of pain in comparison with the rest of methods (F=4.01, p=.01; F=8.14, p=.00). However, the differences in pain between time in all methods were not found to be significant (t=-.85, p=.40; t=.80, p=.42; t=.31, p=.75; t=.19, p=.85).
CONCLUSION
The study results indicate that the method using lanceter is more recommendable than the use of 27G needle only method. Further research is needed to support the current study result with the use of different measurement scales and to determine effective methods of blood sugar test to lower pain and compliance.
