Abstract
Self-monitoring of blood glucose (SMBG) should be part of a regular management plan for patients with
diabetes. Self-monitoring of blood glucose provides information regarding an individual’s dynamic blood
glucose prole. This information can help with the appropriate scheduling of food, activity, and medication.
It is also required for understanding of the timing of blood glucose variations. Lack of regular SMBG predicts
hospitalization for diabetes-related complications. Self-monitoring of blood glucose is an essential tool
for people with diabetes who are taking insulin or for those who experience uctuations in their blood glucose
levels, especially hypoglycemia. Application of practical aspects that aid in easy management of SMBG makes the
task of checking blood glucose more achievable. For patients taking insulin and adjusting their dose, SMBG is
needed for self-management. For others receiving oral medication, proling glucose trends and the conrmation
of high or low blood glucose can be a useful addendum to successful management.

CLINICAL APPLICATIONS
Introduction
Self-monitoring of blood glucose (SMBG) can be a
useful tool in the management of diabetes mellitus.
Patients with diabetes often measure their blood glucose
to detect hypoglycemia and to adjust insulin dose as
needed. Others utilize SMBG to help establish a prole
of blood glucose levels and response to nutrition and
pharmacotherapy. The American Diabetes Association
(ADA) initially established guidelines for SMBG in 1987,
and current recommendations suggest regular SMBG in
persons with diabetes based on each patient’s needs.1,2
Records of SMBG can also be used during consultation
with diabetes health care providers to titrate blood glucose-
lowering agents and to guide physical activity and food
intake.
One objective of Healthy People 2010 is to increase the
number of adults with any type of diabetes who
perform SMBG at least once daily.3 Data from the
Behavioral Risk Factor Surveillance System, representing
25 of 38 states in the United States, reported this to
be 63.4% among all adults with diabetes and 86.7%
among those treated with insulin.4 For patients with
type 1 diabetes mellitus, it is recommended that patients
measure their blood glucose at least three times daily.2
The effectiveness of SMBG has been established for
insulin-treated patients.
There is debate over optimal frequency and timing of
SMBG for those with type 2 diabetes mellitus (T2DM)

not taking insulin. Some health practitioners are skeptical
about the effectiveness of SMBG as a self-management tool.
However, lack of regular SMBG predicts hospitalization
for diabetes-related complications.5 Self-monitoring of
blood glucose has also been shown to signicantly decrease
hemoglobin A1c (A1C).6,7 The ADA recommends using
SMBG as a guide to successful therapy and to achieve
postprandial glucose targets.2
Self-monitoring of blood glucose by persons with diabetes
is an integral part of intensive glycemic treatment and is
widely believed to improve the control of blood glucose
levels and health outcomes. The results of the Diabetes
Control and Complications Trial (DCCT) among persons
with type 1 diabetes mellitus showed that intensive
glycemic control signicantly slowed the progression of
diabetes complications.8 The DCCT protocol required
SMBG at least four times each day and multiple
injections of insulin. Furthermore, the United Kingdom
Prospective Diabetes Study found that a reduction in A1C
was associated with a decreased risk of microvascular
complications in persons with T2DM.9
Specic Goals of Blood Glucose and
Documentation
The target for A1C is less than 7%; this correlates with
an average blood glucose of approximately 150 mg/dl.
Specically, the ADA recommends that preprandial plasma
glucose values range from 70 to 130 mg/dl, and peak
postprandial levels are targeted at <180 mg/dl.2 The use
of SMBG by a person with diabetes can be helpful in
developing a longitudinal glucose prole and as an aid
in making day-to-day decisions. Standards of Medical Care
in Diabetes 2010 also recognizes that there is increased
risk for diabetes at a fasting plasma glucose of 100 to
125 mg/dl or a 2-hour postprandial glucose that is 140
to 199 mg/dl as well as a A1C level that is 5.7% to 6.4%.2
Furthermore, the new standards also recognize the use
of a A1C ≥6.5% as an option for diagnosis of diabetes if
the test is performed by a laboratory using a certied
methodology.2
It is advisable to have the patient record their SMBG values
in a log book. Information about food intake, medication,
and exercise can be important for interpreting the SMBG
results. Keeping a log will also encourage the patient
to acknowledge their SMBG and to contemplate the
potential adjustments they can make with activity and
nutrition. Accurate data are imperative for the health
team to adjust medication, problem solve, and recommend
lifestyle (activity, stress, nutrition) modications for the
patient.
Steps for Self-Monitoring of Blood
Glucose
There are several necessary steps to assure accurate
data from SMBG. To assess a patient’s understanding
of SMBG knowledge, an explanation of the practical
aspects of the procedure is imperative. Table 1 contains
points to consider for successful SMBG and lists several
important steps that should be instituted for SMBG.10–13
Specically, proper use of the strips and general
procedures for meter handling must be understood
appropriately in order to obtain useful data. Since there
are a multitude of meters available on the market, the
information in Table 1 applies to general aspects of
SMBG and user manuals for each individual meter can
be consulted for specic functions, error messages, and
setting date and time. For some meters, the accuracy
can be affected by interfering substances (medication),
temperature, hematocrit level, and user technique.14
In addition, the accuracy of SMBG meters available
has been recommended to produce results within a
20% margin of error.13 Recognition of meter accuracy
variability is important, as many patients will retest
SMBG, obtaining different results that can create concern.
Table 1.
Strip and Meter Handling for Self-Monitoring of
Blood Glucose10–12
Meter and test strips should be handled with clean, dry hands.
Test strips are for single use and unique for each meter.
Test strips must be kept in the original canister, as any moisture
can affect the integrity of the strip, and the containers should be
kept closed. Check for expiration date.
Strips can be tested for accuracy with control solution provided
initially with each meter and should be checked for expiration
date. The control glucose range for the strips appears on the
canister.
Some meters require coding with each canister. Many of the
newer meters do not require coding.
The amount of blood required is usually ver y small.
Many meters easily pull the blood drop into the end of the strip.
Inadequate sample can be a source of error.
Keep meter and supplies in a cool, dry area, not in the car or in
sunlight.
Bring meter into ofce visits with diabetes educator or primary
care provider to test the accuracy comparatively.
Lancing procedures for SMBG require the patient to
fully understand the appropriate steps for successful
blood obtainment (Table 2).15,16 Most SMBG meters come
with some type of lancing device. It will be important
for the patient to demonstrate how to adjust the depth
437

J Diabetes Sci Technol Vol 4, Issue 2, March 2010
Blood sample size can also be a factor for many individuals,
especially if there is lancing difculty or lack of blood
ow. Sample size requirement for some meters is as small
as 0.3 μl. Newer SMBG devices deliver results very quickly,
averaging around ve seconds or less. For the vision
impaired, the size of the screen will need to be evaluated
with a variety of digital output reading font sizes and
information that is available. Some meters contain very
sophisticated features such as food/medication/activity
tracking, premeal and postmeal SMBG “tagging,” and
low blood glucose alerts. The option of using a talking
meter that provides verbal guidance on each step in the
SMBG process is also available. A comprehensive guide to
SMBG devices including size, weight, sample size required,
alternative site testing approval, memory features, warranty,
and other meter aspects are available annually at the
beginning of each year in a resource guide published by
the ADA.13
Cost is a major factor for many patients and often times
becomes the primary factor for SMBG meter selection.
Insurance coverage varies widely in the amount of
copay required and whether a deductible has to be met
rst before a percentage of the supplies are covered.
Some insurance companies will only cover a specic
SMBG meter and supplies, giving the patient no
alternative unless they want to pay for a different device
out of pocket. For many insurance coverage plans,
mail order can be an option to cover the meter, strips,
and lancets as durable medical equipment and will not
factor in under the patient’s prescription benet coverage.
Documented medical necessity can help reimbursement
for exceptions.
Management of Self-Monitoring of Blood
Glucose
Management of SMBG depends on the patient’s level
of diabetes education and/or a person’s general ability
to understand the necessary basic steps for SMBG.
The application of SMBG results for self-management is
necessary for successful diabetes outcomes.17 Goal setting
from a health care and patient team approach can also
be useful as action items for SMBG results. For example,
if the results of SMBG show a consistent pattern of high
fasting glucose levels, then medications that target liver
output of glucose might be helpful. Postprandial glucose
levels (two hours after eating) provide information
regarding the impact of food intake on blood sugar.
Diet modication or medication (some orals or mealtime
insulin) may be useful therapies.
of the lancing device to avoid bruising while effectively
acquiring an adequate blood sample. Alternative sites
other than the nger can be used with many meters;
however, blood sample obtainment can often be
challenging without instruction. There are also lancing
tools that have multiple lancets that are inserted into a
device that rotates a cylinder and provides an alternative
to handling individual sharps.
Table 2.
Lancing Procedure for Self-Monitoring of Blood
Glucose13,15
Site preparation: Clean area with warm, soapy water and dry.
Food residue can be a source of false high blood sugar values.
Lancet devices to obtain blood can vary and all use a lancet to
prick the skin. Thin, sharp lancets are more comfortable. Lancets
should not be reused or cleaned, as they quickly become dull.
Depth set ting on the lancet device controls the penetration of
the stick and can be adjusted for best comfort and size of blood
sample. Most meters require very small samples—less than a
small teardrop.
Lancet should be applied rmly to the clean, dry nger, but not
with force.
Sides of the nger should be used, as there is less pain.
Use of the third, fourth, and fth digits may be preferable to
spare index nger and thumb.
Alternate test sites (upper arms and thighs) are approved for
many meter s. Finger tips or the outer palm are preferred and are
more accurate.
Obtainment of blood sample should be a gentle “milking” from
the base of the nger to the lanced tip. Pressure directly on the
site of lancing is not recommended.
Disposal of lancets and SMBG testing supplies should be done
according to local laws for sharps. In many locations, a hard
plastic container with a screw top can be disposed of in the
household trash.
Choosing a Self-Monitoring of Blood
Glucose Device
There are several considerations for pairing a meter
with each patient. Assessment of the patient’s ability to
follow the necessary steps to successfully obtain a SMBG
reading will be essential. Dexterity is a very important
factor to consider. Some meters facilitate the use of
strips that are contained with multiple use containers
or “drums” that load much like a roll of lm into a
camera. Other meters contain multiple blood glucose
strips that are in the form of a circulating wheel that
rotates and eliminates the need to handle individual test
strips. Many SMBG meters have strips that “wick” the
blood sample into the end of the strip, allowing visual
inspection to assure an appropriate sample is obtained.
438

J Diabetes Sci Technol Vol 4, Issue 2, March 2010
The role of physical activity and diet will be needed to
assess how to appropriately adjust self-management.
Treatment should be outlined to include goal setting
for self-care behavior.18 Specic schedules for SMBG
will vary for each patient. Short periods of intense SMBG,
before and after each meal and at bedtime, will provide
data to identify glucose patterns. This can be an
important adjunct to A1C to distinguish between
fasting, preprandial hyperglycemia, and postprandial
hyperglycemia. Alternatively, patients may use a staggered
schedule of checking at various times of day throughout
the week. For example, the use of a preprandial
and two-hour postprandial SMBG gives the patient
immediate feedback on their food choices for that meal.
Postprandial spikes may be an independent risk factor
for diabetes complications, even when glycemic control
appears to be satisfactory.19 Useful tips for health
care providers and patients are outlined in Table 3.
Careful consideration should be given to assessing the
patient’s ability to comprehend and retain the procedure of
SMBG that can often be technical. Attention to literacy
and numeracy skills will be an equally important step
in successful SMBG.20 Patient demonstration of SMBG to
the diabetes educator or health care provider is critical.
patient and the health care provider should be agreed upon
to assure periodic assessment of SMBG timing, accuracy
of testing, and goals. For example, when medicine dose is
being adjusted, more frequent SMBG may be needed to
assure response to therapy. Once therapy is established,
SMBG can often be altered to accommodate patient
schedules. Targeting blood glucose uctuations around
meals or increased activity can provide useful information.
There is also the option of a continuous glucose
monitoring system (CGMS). Through a sensor that is
inserted subcutaneously, the patient wears the CGMS for
an extended period of time (usually 3 days) to capture
blood glucose levels day and night.13 While CGMS is
an ideal option to monitor blood glucose spikes and
potential lows, insurance coverage is variable, and
interpretation of the data will be necessary by a qualied
individual (diabetologist, certied diabetes educator, or
endocrinologist).
Other Summary Points
Diabetes requires self-management and adherence to
treatment guidelines such as those recommended by the
ADA; among these is regular SMBG to monitor success
with the diabetes treatment plan. The cost-effectiveness
of SMBG has also been questioned, and insurance
coverage or affordability of glucose test strips must be
considered.21 Some research has shown that providing
SMBG devices at no charge can improve the rate of
testing.22 Self-monitoring of blood glucose can serve
an important role in improving patient knowledge of
glucose levels and the effects of different behaviors on
blood glucose outcomes.

Use simple and specic steps at the patient’s level of
comprehension.
Be sure the patient can demonstrate the steps for SMBG.
Give your patient written recommendations for frequency and
times of testing and desired results.
Obser ve SMBG procedure at follow-up visits.
Ask the patient to assess the relationship of SMBG with exercise,
food, medications, and stress.
Specif y which SMBG values are most problematic (especially
low blood glucose) and discuss solutions with the patient.
Acknowledge the patient for goals achieved with SMBG.
Tools, such as SMBG, can help patients with glucose
regulation. The ADA recommends that patients receive
initial instruction for SMBG and routine follow-up to use
data obtained to adjust therapy.2 The frequency of SMBG
testing should be clearly outlined with emphasis on testing
during illness, preprandial and/or postprandial, and
during times of potential low blood sugar. Patients who
use carbohydrate counting to adjust insulin doses and
postprandial glucose will need SMBG goals set that may be
more intensive than for persons who are maintained with
good control using oral medications. A dialogue between the

... Recent technological advancements necessitate further research to assess their impact on patients' lives. As is well established, self-monitoring of blood glucose (SMBG) can be beneficial in preventing long-term complications and helpful during consultations [24]. Its recent alternatives, continuous glucose monitoring (CGM) systems, provide more precise and detailed information on glucose levels, and are proven to improve glycemic control [25]. ...

Background: Diabetes-related distress (DD) significantly impacts self-management and quality of life (QoL) in individuals with type 1 diabetes (T1D). While previous research has established a strong link between DD and glycemic control in type 2 diabetes, the relationship remains less consistent in T1D. Additionally, continuous glucose monitoring (CGM) has been shown to improve glycemic outcomes, yet its effects on self-management and QoL are still debated. This study aimed to examine the relationship between DD, self-management efficacy (SME), and QoL in T1D, incorporating both physiological and behavioral indicators. Furthermore, differences between CGM-users and non-users were investigated. Methods: A cross-sectional study including 108 T1D patients was conducted. Participants completed several validated self-report measures, including the Diabetes Distress Scale (DDS), Diabetes Self-Management Questionnaire (DSMQ), and Audit of Diabetes-Dependent Quality of Life (ADDQoL-19). HbA1c levels and CGM usage were retrieved from medical records. Structural equation modeling (SEM) was used to examine the relationships between DD, self-management, and QoL. Results: Distress level (DDS) had a significant negative effect on SME (β = −0.47, p < 0.001), suggesting that higher distress levels are associated with lower self-management. In contrast, SME showed no significant impact on quality of life (β = 0.03, p = 0.779). However, the relationship between quality of life and distress was significant and negative (β = −0.37, p < 0.001), meaning that higher distress levels are linked to a lower quality of life. No significant differences in DD, SME, HbA1c, or QoL were found among CGM users and non-users. Conclusions: DD significantly impacts self-management and QoL in individuals with T1D. Therefore, incorporating PROs on DD and on behavioral aspects of self-management alongside HbA1c levels in clinical care is essential for optimizing treatment plans and improving physical health outcomes. While CGM technology facilitates glucose regulation, it does not inherently improve QoL, which is more closely linked to distress.
... The CGM devices provide continuous monitoring of blood glucose levels, thereby offering an all-encompassing picture of glucose fluctuations throughout the day and night [8,10]. In contrast to conventional glucose monitoring methods, which require intermittent finger stick tests, CGM devices use sensors positioned under the skin to measure sugar levels continuously [11][12][13]. This real-time data help patients and clinicians to make decisions about identifying appropriate drugs for intervention and adjusting drug therapy. ...

Federally Qualified Health Centers (FQHCs) provide service to medically underserved areas and communities, providing care to over 32 million patients annually. The burden of diabetes is increasing, but often, the vulnerable communities served by FQHCs lag in the management of the disease due to limited resources and related social determinants of health. With the increasing adoption of technologies in health care delivery, digital tools for continuous glucose monitoring (CGM) are being used to improve disease management and increase patient engagement. In this viewpoint, we share insights on the implementation of a CGM program at an FQHC, the Community-University Health Care Center (CUHCC) in Minneapolis, Minnesota. Our intent is to improve diabetes management through better monitoring of glucose and to ensure that the CGM program enables our organization’s overarching digital strategy. Given the resource limitations of our population, we provided Libre Pro devices to uninsured patients through grants to improve health care equity. We used an interdisciplinary approach involving pharmacists, nurses, and clinicians and used hemoglobin A1c (HbA1c) levels as a measure of diabetes management. We assessed the CGM program and noted key aspects to guide future implementation and scalability. We recruited 148 participants with a mean age of 54 years; 39.8% (59/148) self-identified their race as non-White, 9.5% (14/148) self-identified their ethnicity as Hispanic or Latino, and one-third (53/148, 35.8%) were uninsured. Participants had diverse language preferences, with Spanish (54/148, 36.5%), English (52/148, 35.1%), Somali (21/148, 14.2%), and other languages (21/148, 14.2%). Their clinical characteristics included an average BMI of 29.91 kg/m2 and a mean baseline HbA1c level of 9.73%. Results indicate that the CGM program reduced HbA1c levels significantly from baseline to first follow-up (P<.001) and second follow-up (P<.001), but no significant difference between the first and second follow-up (P=.94). We share key lessons learned on cultural and language barriers, the digital divide, technical issues, and interoperability needs. These key lessons are generalizable for improving implementation at FQHCs and refining digital strategies for future scalability.
... [24,25] SMBG has been defined as an essential way to promote glycemic control in T2DM patients treated with insulin. [26,27] Given the ease of use of SMBG, this approach can reduce frequent referrals of patients to health care and diagnostic centers [7] and also create motivation in terms of adjusting insulin doses in diabetic patients treated with insulin as a strategy to control and decrease HbA1 C levels. [24] Although frequent monitoring of blood glucose (at least once daily) among insulin-treated T2DM patients has been reported to significantly improve HbA1 C levels, low-frequency monitoring has also been reported to be effective. ...

Background Reducing the frequency of self-monitoring of blood sugar, due to needle phobia, pain, stress, and costs associated with the procedure, can improve patient compliance and quality of life, provided that adequate blood sugar control is maintained. This study aimed to evaluate the effect of low-frequency blood glucose self-monitoring (LFBGSM) on glycosylated hemoglobin (HbA1C) levels among older adults living with type 2 diabetes mellitus (T2DM), treated with or without insulin. Materials and Methods This randomized controlled trial with a parallel design was conducted on 121 older adults with T2DM in Sabzevar, Iran, between 2018 and 2020. Initially, subjects were stratified based on the type of treatment (with or without insulin) and then randomly assigned to intervention (LFBGSM) and control (no blood glucose self-monitoring [no-BGSM]) groups. HbA1C levels were measured at the beginning of the study and 3 months later for all study groups. Results The mean age of participants treated with and without insulin was 64.3 ± 9.60 and 64.7 ± 5.01 years, respectively. The ANCOVA test revealed a significant difference in the mean HbA1C levels among the four groups 3 months postintervention (P < 0.001). The HbA1C scores significantly decreased in the LFBGSM groups and increased in the no-BGSM groups at 3 months postintervention (insulin/LFBGSM, insulin/no-BGSM, noninsulin/LFBGSM, and noninsulin/no-BGSM: 7.74 ± 0.76, 8.34 ± 1.53, 7.70 ± 0.75, and 8.14 ± 1.11, respectively) compared to baseline (8.25 ± 0.67, 8.03 ± 0.64, 8.08 ± 0.69, and 7.83 ± 0.74, respectively). The least significant difference post hoc tests showed significant differences between specific groups, emphasizing subtle responses to interventions (P values ranging from 0.001 to 0.929). Conclusion Findings suggest a significant reduction in HbA1C scores within the LFBGSM groups, while a discernible increase is observed in the no-BGSM groups over the 3 months. These findings underscore the efficacy of the interventions and emphasize the crucial role of personalized approaches in optimizing glycemic control for individuals with diabetes.
... The current standard of DM monitoring is through the invasive blood pricking technique for the detection of glucose (Kirk and Stegner, 2010). Typically, this method is reliable; however, the repetitive pricking in the long term is inconvenient for patients and can simply cause irritation and infections (Reddy et al., 2022). ...

Diabetes mellitus (DM) is a prevalent disorder with an urgent need for continuous, precise, and on-site biomarker monitoring devices. The continuous monitoring of DM biomarkers from different biological matrices will become routine in the future, thanks to the promising biosensor design. Lately, employing different nanomaterials in biosensor receptor parts has had a great impact on smart DM monitoring. Among them, gold nanostructures (AuNSs) have arisen as highly potential materials in fabricating precise DM biosensors due to their unique properties. The present study provides an update on the applications of AuNSs in biosensors for detecting glucose as well as other DM biomarkers, such as glycated hemoglobin (HbA1c), glycated albumin (GA), insulin, insulin antibodies, uric acid, lactate, and glutamic acid decarboxylase antibodies (GADA), with a focus on the most important factors in biosensor performance such as sensitivity, selectivity, response time, and stability. Specified values of limit of detection (LOD), linear concentrations, reproducibility%, recovery%, and assay time were used to compare studies. In conclusion, AuNSs, owing to the wide electrochemical potential window and low electrical resistivity, are valuable tools in biosensor design, alongside other biological reagents and/or nanomaterials.
... For self-monitoring of glucose, its lower prevalence is not surprising because it is only recommended to patients with T2DM if they have poorly managed diabetes or are on insulin. 32 The observation that medication taking was the most prevalent among the self-care behaviors examined is consistent with several studies. 22,33 For instance, a study on the Arab population utilized the SDSCA questionnaire and found that medication taking had the highest prevalence (92.9%) and that exercise had the lowest prevalence (27.1%). ...

Purpose: The purpose of this study was to examine the relationship between self-management behaviors (eg, healthy eating, being active, medication taking, glucose monitoring, feet check), sociodemographic factors, disease-related characteristics, and health literacy among patients with type 2 diabetes in Singapore. Methods: Data were analyzed from a nationwide survey conducted between 2019 and 2020 (n = 387). Self-management behaviors were assessed using the Dietary Approaches to Stop Hypertension questionnaire, the Global Physical Activity Questionnaire, and a diabetes care questionnaire. A linear regression model was generated to examine the association of healthy eating with the variables of interest (sociodemographic factors, disease-related characteristics, and health literacy), and logistic regression models were generated to investigate the significant correlates of the remaining self-care behaviors. Results: Regression models showed that the 5 self-care behaviors have different correlates. Nonetheless, compared to individuals aged 50 to 64 years, those aged 65 years and above were less likely to be active, adhere to their medication prescription, and check their feet. Individuals with a higher number of diabetes-related complications were less likely to be sufficiently active but more likely to monitor their glucose level and check their feet. Moreover, individuals with poor health literacy were more likely to eat healthily and be sufficiently active. Conclusions: Programs related to self-care behaviors can be tailored to specific demographics to improve their uptake in the population. Furthermore, encouraging comprehensive self-care behaviors in those aged 65 years and above is crucial for effective diabetes management.
... The significance of regular glucose monitoring is widely acknowledged [3]. Self-measurement of blood glucose (SMBG) requires taking blood samples regularly [4], while CGM technology allows non-invasive monitoring of glucose at intervals of 5 or 15 minutes. Real-time glucose readings empower diabetic patients to self-manage their conditions through lifestyle adjustment [5]. ...

Effective blood glucose regulation is essential for both diabetic and non-diabetic individuals. Finger-prick methods are inconvenient and painful, while continuous glucose monitoring (CGM) systems are costly and require frequent sensor replacements. This paper proposes an innovative approach for continuous real-time blood glucose level estimation using non-invasive physiological signals and ensemble regression techniques. We observed significant differences in the predictive power of individual features and overall model performance between the diabetic and the non-diabetic groups. The best model for the diabetic group achieved better performance (R 2 = 0.50) compared to the best model for the non-diabetic group (R 2 = 0.27). However, when evaluated for clinical accuracy, the non-diabetic models outperformed the diabetic models. The best non-diabetic model had 100% of predictions in the clinically acceptable zones of the Clarke Error Grids (CEG), while the best diabetic model had only 91%. The between-group differences in model performance are likely due to the variations in underlying glucose dynamics between diabetic and non-diabetic individuals. Our findings highlight the necessity of collecting and sharing large multimodal datasets from both diabetic and non-diabetic populations, as well as evaluating glucose prediction models from both mathematical and clinical accuracy.

The pancreatic duct is an intrapancreatic restricted tube that connects the pancreas to the common bile duct. The pancreatic duct transports pancreatic juice to the common bile duct for digesting. Pancreatic duct diameter is an important index in assessing pancreatic duct pathology as well as the pancreas. Duct obstruction may lead to dilatation due to cancer of the pancreas, pancreatitis, cholelithiasis or duodenal pathology. Recent studies have established a direct relationship between dilatation of the pancreatic duct and cancer of the pancreas. The objective of this study is to determine the pancreatic duct diameter in apparently healthy individuals in Gaborone and its relationship with anthropometric variables. Sonographic determination of the pancreatic duct diameter is very important for providing an objective evaluation of the pancreas and the nature and extent of disease if pathologic. Establishment of a baseline reference value for the pancreatic duct diameter is therefore important for providing a normogram in healthy individuals in Gaborone, Botswana. A total of 384 randomly selected individuals and 330 pancreatic duct diameter measurements were used for the study between July 2020 and May 2021. Optimum sonographic scanning technique described by Taylor et al was utilized in measuring the pancreatic duct diameter in this study. The mean pancreatic duct diameter was: 2.40±0.58mm for the head, 2.10±0.50mm for the body and 1.84±0.54mm for the tail. The mean pancreatic duct diameter for the present study was 2.11±0.50mm. The pancreatic duct diameter increased with age from 45years, indicating statistically significant relationship (P-value=0.0492). There was no significant statistical difference in the overall mean pancreatic duct diameter between male and female (p > 0.05). The present study has established that the pancreatic duct diameter for adults in Gaborone is 2.11±0.50mm and could be used in clinical setting as baseline reference value. The normogram also will be a valuable tool in age related pancreatic duct pathologies.

Objective The aim of this study was to synthesize scientific evidence on the influence of health literacy and numerical knowledge on self-monitoring of capillary blood glucose. Methods Adhering to the PRISMA guidelines and the principles of the Joanna Briggs Institute, a comprehensive search was conducted across multiple databases, including CINAHL, Cochrane, Embase, LILACS, PubMed, Scopus, Web of Science, Google Scholar, OPENGREY, and NDLTD. The review included studies published in any language that examined the relationship between HL, numeracy, and SMBG. Results A total of 12 studies met the inclusion criteria. These studies utilized various assessment tools, such as the Brief Test of Functional Health Literacy in Adults (B-TOFHLA) and the Diabetes Numeracy Test (DNT-15), to evaluate health literacy and numeracy levels. The findings revealed a significant association between adequate HL and numeracy and improved SMBG practices. Specifically, individuals with sufficient health literacy were more likely to monitor their blood glucose levels regularly and make appropriate treatment adjustments based on their readings. Conclusion The results indicated that numeracy skills and health literacy are critical determinants of effective SMBG, influencing the frequency and accuracy of self-care practices in diabetes management. These findings highlight the urgent need for educational interventions tailored to enhance these skills, which could lead to improved health outcomes for individuals with diabetes.

Background: Reducing the risks of complications is a primary goal of diabetes management, with effective glycemic control a key factor. Glucose monitoring using continuous glucose monitoring (CGM) technology is an important part of diabetes self-management, helping patients reach and maintain targeted glucose and glycated hemoglobin (HbA1c) levels. Although clinical guidelines recommended CGM use, coverage by Medicaid is limited, likely because of cost concerns. Objective: To assess the cost-effectiveness of FreeStyle Libre CGM systems, compared with capillary-based self-monitoring of blood glucose (SMBG), in US individuals with type 2 diabetes mellitus using basal insulin. Methods: A patient-level microsimulation model was used to compare CGM with SMBG for a population of 10,000 patients. A 10-year horizon was used, with an annual discount rate of 3.0% for costs and utilities. Model population characteristics were based on US national epidemiology data. Patient outcomes were based on published clinical trials and real-world studies. Annual costs, reflective of 2023 values, included CGM and SMBG acquisition costs and the costs of treating diabetic ketoacidosis, severe hypoglycemia, and diabetes complications. The effect of CGM was modeled as a persistent 1.1% reduction in HbA1c relative to SMBG based on US real-world evidence. Disutilities were based on published clinical trials and other relevant literature. The primary outcome was cost per quality-adjusted life-year (QALY) gained. Sensitivity analyses were performed to test the validity of the model results when accounting for a plausible variation of inputs. Results: In the base case analysis, CGM was dominant to SMBG, providing more QALYs (6.18 vs 5.97) at a lower cost (70,137vs70,137 vs 71,809) over the 10-year time horizon. A 10,456increaseinglucosemonitoringcostswasoffsetbya10,456 increase in glucose monitoring costs was offset by a 12,127 reduction in treatment costs. Cost savings reflected avoidance of acute diabetic events (savings owing to reductions in severe hypoglycemia and diabetic ketoacidosis were 271and271 and 2,159, respectively) and a reduced cumulative incidence of diabetes complications, particularly renal failure (saving 5,292),myocardialinfarction(saving5,292), myocardial infarction (saving 1,996), and congestive heart failure (saving 1,061).Scenarioanalyseswereconsistentwiththebasecaseresults,andtheincrementalcosteffectivenessratioforCGMvsSMBGrangedfromdominanttocosteffective.Inprobabilisticanalysis,CGMwas1001,061). Scenario analyses were consistent with the base case results, and the incremental cost-effectiveness ratio for CGM vs SMBG ranged from dominant to cost-effective. In probabilistic analysis, CGM was 100% likely to be cost-effective at a willingness-to-pay threshold of 50,000/QALY. Conclusions: CGM is cost-effective compared with SMBG for US patients with type 2 diabetes mellitus receiving basal insulin therapy. This suggests that state Medicaid programs could benefit from broader coverage of CGM.

Background Improved blood-glucose control decreases the progression of diabetic microvascular disease, but the effect on macrovascular complications is unknown. There is concern that sulphonylureas may increase cardiovascular mortality in patients with type 2 diabetes and that high insulin concentrations may enhance atheroma formation. We compared the effects of intensive blood-glucose control with either sulphonylurea or insulin and conventional treatment on the risk of microvascular and macrovascular complications in patients with type 2 diabetes in a randomised controlled trial. Methods 3867 newly diagnosed patients with type 2 diabetes, median age 54 years (IQR 48-60 years), who after 3 months' diet treatment had a mean of two fasting plasma glucose (FPG) concentrations of 6.1-15.0 mmol/L were randomly assigned intensive policy with a sulphonylurea (chlorpropamide, glibenclamide, or. glipizide) or with insulin, or conventional policy with diet. The aim in the intensive group was FPG less than 6 mmol/L. in the conventional group, the aim was the best achievable FPG with diet atone; drugs were added only if there were hyperglycaemic symptoms or FPG greater than 15 mmol/L. Three aggregate endpoints were used to assess differences between conventional and intensive treatment: any diabetes-related endpoint (sudden death, death from hyperglycaemia or hypoglycaemia, fatal or non-fatal myocardial infarction, angina, heart failure, stroke, renal failure, amputation [of at least one digit], vitreous haemorrhage, retinopathy requiring photocoagulation, blindness in one eye,or cataract extraction); diabetes-related death (death from myocardial infarction, stroke, peripheral vascular disease, renal disease, hyperglycaemia or hypoglycaemia, and sudden death); all-cause mortality. Single clinical endpoints and surrogate subclinical endpoints were also assessed. All analyses were by intention to treat and frequency of hypoglycaemia was also analysed by actual therapy. Findings Over 10 years, haemoglobin A(1c) (HbA(1c)) was 7.0% (6.2-8.2) in the intensive group compared with 7.9% (6.9-8.8) in the conventional group-an 11% reduction. There was no difference in HbA(1c) among agents in the intensive group. Compared with the conventional group, the risk in the intensive group was 12% lower (95% CI 1-21, p=0.029) for any diabetes-related endpoint; 10% lower (-11 to 27, p=0.34) for any diabetes-related death; and 6% lower (-10 to 20, p=0.44) for all-cause mortality. Most of the risk reduction in the any diabetes-related aggregate endpoint was due to a 25% risk reduction (7-40, p=0.0099) in microvascular endpoints, including the need for retinal photocoagulation. There was no difference for any of the three aggregate endpoints the three intensive agents (chlorpropamide, glibenclamide, or insulin). Patients in the intensive group had more hypoglycaemic episodes than those in the conventional group on both types of analysis (both p<0.0001). The rates of major hypoglycaemic episodes per year were 0.7% with conventional treatment, 1.0% with chlorpropamide, 1.4% with glibenclamide, and 1.8% with insulin. Weight gain was significantly higher in the intensive group (mean 2.9 kg) than in the conventional group (p<0.001), and patients assigned insulin had a greater gain in weight (4.0 kg) than those assigned chlorpropamide (2.6 kg) or glibenclamide (1.7 kg). Interpretation Intensive blood-glucose control by either sulphonylureas or insulin substantially decreases the risk of microvascular complications, but not macrovascular disease, in patients with type 2 diabetes. None of the individual drugs had an adverse effect on cardiovascular outcomes. All intensive treatment increased the risk of hypoglycaemia.

By the most recent estimates, 18.8 million people in the U.S. have been diagnosed with diabetes and an additional 7 million are believed to be living with undiagnosed diabetes. At the same time, 79 million people are estimated to have blood glucose levels in the range of prediabetes or categories of increased risk for diabetes. Thus, more than 100 million Americans are at risk for developing the devastating complications of diabetes (1). Diabetes self-management education (DSME) is a critical element of care for all people with diabetes and those at risk for developing the disease. It is necessary in order to prevent or delay the complications of diabetes (2–6) and has elements related to lifestyle changes that are also essential for individuals with prediabetes as part of efforts to prevent the disease (7,8). The National Standards for Diabetes Self-Management Education are designed to define quality DSME and support and to assist diabetes educators in providing evidence-based education and self-management support. The Standards are applicable to educators in solo practice as well as those in large multicenter programs—and everyone in between. There are many good models for the provision of diabetes education and support. The Standards do not endorse any one approach, but rather seek to delineate the commonalities among effective and excellent self-management education strategies. These are the standards used in the field for recognition and accreditation. They also serve as a guide for nonaccredited and nonrecognized providers and programs. Because of the dynamic nature of health care and diabetes-related research, the Standards are reviewed and revised approximately every 5 years by key stakeholders and experts within the diabetes education community. In the fall of 2011, a Task Force was jointly convened by the American Association of Diabetes Educators (AADE) and the American Diabetes Association …

Self-monitoring of blood glucose (SMBG) is an important adjunct to hemoglobin A1c (HbA1c) testing. This action can distinguish between fasting, preprandial, and postprandial hyperglycemia; detect glycemic excursions; identify and monitor resolution of hypoglycemia; and provide immediate feedback to patients about the effect of food choices, activity, and medication on glycemic control. Pattern analysis is a systematic approach to identifying glycemic patterns within SMBG data and then taking appropriate action based upon those results. The use of pattern analysis involves: (1) establishing pre- and postprandial glucose targets; (2) obtaining data on glucose levels, carbohydrate intake, medication administration (type, dosages, timing), activity levels and physical/emotional stress; (3) analyzing data to identify patterns of glycemic excursions, assessing any influential factors, and implementing appropriate action(s); and (4) performing ongoing SMBG to assess the impact of any therapeutic changes made. Computer-based and paper-based data collection and management tools can be developed to perform pattern analysis for identifying patterns in SMBG data. This approach to interpreting SMBG data facilitates rational therapeutic adjustments in response to this information. Pattern analysis of SMBG data can be of equal or greater value than measurement of HbA1c levels.

The Coalition for Clinical Research—Self-Monitoring of Blood Glucose Scientific Board, a group of nine academic clinicians and scientists from the United States and Europe, convened in San Francisco, California, on June 11–12, 2008, to discuss the appropriate uses of self-monitoring of blood glucose (SMBG) and the measures necessary to accurately assess the potential benefit of this practice in noninsulin-treated type 2 diabetes mellitus (T2DM). Thirteen consultants from the United States, Europe, and Canada from academia, practice, and government also participated and contributed based on their fields of expertise. These experts represent a range of disciplines that include adult endocrinology, pediatric endocrinology, health education, mathematics, statistics, psychology, nutrition, exercise physiology, and nursing. This coalition was organized by Diabetes Technology Management, Inc. Among the participants, there was consensus that:

Our systematic review and meta-analysis of the benefit of self-monitoring of blood glucose (SMBG) in improving glycemic control in type 2 diabetes was published in 2008. With the few studies that have emerged afterward, we undertook subsequent meta-analysis of the available evidence to update the results. Clinical trials of SMBG were identified through electronic searches (MEDLINE, EMBASE, and The Cochrane Library) up to and including June 2009. Studies were included if they met the following inclusion criteria: (1) randomized controlled trial comparing SMBG versus non-SMBG in type 2 diabetes patients not using insulin and (2) hemoglobin A1c (HbA(1c)) reported as an outcome measure. The efficacy was estimated with the mean difference in the changes of HbA(1c) from baseline to final assessment between the SMBG and the non-SMBG groups. SMBG was effective in reducing HbA(1c) in non-insulin-treated type 2 diabetes (pooled mean difference, -0.24%; 95% confidence interval, -0.34% to -0.14%; P < 0.00001). Glycemic control significantly improved among the subgroup of patients whose baseline HbA(1c) was >or=8%. In contrast, no significant effect of SMBG was detected in patients who had HbA(1c) <8%. The available evidence suggests the usefulness of SMBG in improving glycemic control in non-insulin-treated type 2 diabetes as demonstrated by the reduction of HbA(1c) levels. In particular, SMBG proved to be useful in the subgroup of patients whose baseline HbA(1c) was >or=8%.
