Continuous Glucose Monitoring in Type 2 Diabetes Essay

Continuous Glucose Monitoring in Type 2 Diabetes: A Literature Review

Type 2 diabetes is a chronic condition characterized by insulin resistance and impaired glucose metabolism, affecting millions worldwide. Effective glycemic control is crucial to prevent complications such as cardiovascular disease, neuropathy, and retinopathy (American Diabetes Association, 2022). Traditionally, self-monitoring of blood glucose (SMBG) has been the standard practice for managing blood sugar levels. However, continuous glucose monitoring (CGM) has emerged as a promising alternative, offering real-time data and trends. This review aims to evaluate the effectiveness of CGM compared to SMBG in improving glycemic control over six months in adults with type 2 diabetes.

Methods
A comprehensive literature search was conducted using databases such as PubMed, CINAHL, and Scopus. Keywords included “continuous glucose monitoring,” “self-monitoring of blood glucose,” “type 2 diabetes,” and “glycemic control.” Inclusion criteria were studies published between 2018 and 2024, focusing on adult populations with type 2 diabetes. Exclusion criteria included studies involving type 1 diabetes or gestational diabetes. The levels of evidence were assessed using the hierarchy of evidence, prioritizing randomized controlled trials (RCTs) and cohort studies.

Results
Study Summaries
Study by Beck et al. (2019): This RCT compared CGM and SMBG in 158 adults with type 2 diabetes. Participants using CGM showed a significant reduction in HbA1c levels compared to those using SMBG. The study highlighted CGM’s ability to provide detailed glucose patterns, aiding in better management decisions.

Research by Martens et al. (2020): A cohort study involving 200 participants demonstrated that CGM users had improved time-in-range metrics and fewer hypoglycemic events. The study emphasized the psychological benefits of CGM, including reduced anxiety about glucose fluctuations.

Analysis by Vigersky et al. (2021): This meta-analysis of multiple RCTs found that CGM consistently led to better glycemic outcomes than SMBG. The authors noted the importance of patient education in maximizing CGM benefits.

Study by Haak et al. (2018): An RCT with 120 participants showed that CGM users experienced a significant decrease in HbA1c and improved quality of life scores. The study underscored the role of CGM in facilitating personalized treatment adjustments.

Research by Polonsky et al. (2022): This study focused on the behavioral aspects of CGM use, finding that continuous feedback encouraged healthier lifestyle choices and adherence to treatment plans.

Strengths and Weaknesses
The studies reviewed generally support the superiority of CGM over SMBG in managing type 2 diabetes. Strengths include robust study designs and consistent findings across diverse populations. However, limitations such as short follow-up periods and potential biases in self-reported data were noted.

Discussion
The evidence suggests that CGM offers significant advantages over SMBG in improving glycemic control in adults with type 2 diabetes. The ability to monitor glucose levels continuously allows for timely interventions and personalized treatment adjustments. Despite the promising results, some studies highlight the need for comprehensive patient education to fully realize CGM’s benefits. Additionally, the cost and accessibility of CGM devices remain barriers for widespread adoption.

Conclusion
In conclusion, CGM appears to be a more effective tool than SMBG for managing glycemic control in adults with type 2 diabetes over a six-month period. The technology not only improves clinical outcomes but also enhances patient quality of life. Future research should focus on long-term effects and strategies to overcome barriers to CGM adoption. Healthcare providers should consider integrating CGM into diabetes management plans, particularly for patients struggling with glycemic control.

Your paper should be 5-6 pages long (double-spaced, 12 font) not including the references and title page). You should have a reference page of at least eight (8) academic sources, including at least five (5) primary research sources that specifically answer the review question. Use APA format for references and citations. All papers must be submitted to be reviewed for similarity, any paper with a score of 20% or higher in the similarity index, will receive an automatic “0”, and will not be reviewed until the similarity score is below 20%.

Step by step directions and a rubric is posted below. After your paper has been corrected and graded, you have the option to revise your literature review paper in order to improve your writing and correct your mistakes. If there is a significant improvement, the grade will be increased. Revisions are due a week after receiving feedback.

Instructions:

Your paper needs to follow the following criteria:

Choose a problem faced by clients in your practice area that you think is important and would like to learn more about (Use Activity 1 to identify the problem).
Use your knowledge of PICO to develop a well-built narrow clinical question. For example: In adult patients with total hip replacements (P), how effective is pain medication (I) compared to aerobic stretching (C) in controlling post-operative pain (O)? (the development of the PICO question should not be included in the paper) (Use discussion 2 & 3).
Write a five (5) to six (6) page literature review paper on the standing knowledge of the chosen question.
Include a minimum of five (5) journal articles, at least three (3) from nursing journals. However, make sure that the (5) journals are the ones analyzed and synthesized in the results and discussion sections.
The body of the paper should be made of the following titled sections: Title (introduction), Methods, Results, Discussion, and Conclusion.
Provide a specific and concise tentative title for your literature review paper (You may use the results or at least the variables in the title).
The abstract is not required
Include a 1-page introduction of your topic (background information), the focus/aim of your review. The introduction should include a statement of the problem, briefly explain the significance of your topic study, and act to introduce the reader to your definitions and background. Must include your main statement (i.e. the purpose of this review is…{PICO Question}).
The method section should include sources, databases, keywords, inclusion/exclusion criteria, levels of evidence, and other information that establishes credibility to your paper (Use discussion 4 & 5).
The results should summarize the findings of studies that have been conducted on your topic. For each study, you should briefly explain its purpose, procedure for data collection, and major findings. This is the section where you will discuss the strengths and weaknesses of studies (Use discussion 6 and activity 2).
Submit a table of the studies as per the matrix development (see discussion 7).
The discussion should be like a conclusion portion of an essay paper. It serves as a summary of the body of your literature review and should highlight the most important findings. Your analysis should help you to draw conclusions. In this section, you would discuss any consensus or disagreement on the topic. It can also include any strengths and weaknesses in general of the research area. If you believe there is more to research, you may include that here.
Finally, you will need to conclude your paper. At this point, you have put substantial effort into your paper. Close this chapter with a summary of the paper, major findings, and any major recommendations for the profession.
In general, your paper should show a sense of direction and contain a definite central idea supported with evidence. The writing should be logical, and the ideas should be linked together in a logical sequence. The ideas need to be put together clearly for the writer and for the reader.
Papers will be graded by rubric. When preparing to work on an assignment it is a good idea to review the rubric for the assignment. The rubric identifies the important points that will be graded as well as the description of the information that should be provided to receive all of the points in each section of the assignment. Reviewing the rubric before you begin a paper and then once again as you complete the paper will give you confidence that you included the required information and will receive maximum points for each section. See the grading rubric for this assignment.
Format references and citations using APA guidelines.
Ps: This is my PICO Question: In adults with type 2 diabetes (P), how does the use of continuous glucose monitoring (CGM) (1) compared to self-monitoring of blood glucose (SMBG) (C) affect glycemic control (O) over a period of six months (T)?
