Pilot study of random finger prick glucose testing as a screening tool for type 2 diabetes mellitus in the emergency department

Assessment of glycaemic status in adult hospital patients for the detection of undiagnosed diabetes mellitus: A systematic review

AIM

In-hospital blood glucose testing is commonplace, particularly in acute care. In-hospital screening for hyperglycaemia may present a valuable opportunity for early diabetes diagnosis by identifying at-risk individuals. This systematic review investigates the extent to which random blood glucose testing in acute and inpatient hospital settings predicts undiagnosed diabetes.

METHODS

Two databases were systematically searched for studies in which adult patients received an in-hospital random blood glucose test, followed by a diagnostic HbA1c test. The primary outcome was the proportion of hyperglycaemic individuals diagnosed with diabetes by HbA1c.

RESULTS

A total of 3245 unique citations were identified, and 12 were eligible for inclusion. Ten different blood glucose thresholds, ranging from 5.5 to 11.1 mmol/L, were used to detect hyperglycaemia, indicating that there is no consistent clinical definition for hyperglycaemia. The proportion of participants with hyperglycaemia in each study ranged from 3.3% to 62.1%, with a median (Q₁ , Q₃ ) of 34.5% (5.95%, 61.1%). The proportion of hyperglycaemic participants found to have a diabetes-range HbA1c varied from 4.1% to 90%, with a median (Q₁ , Q₃ ) of 18.9% (11.5%, 61.1%). Meta-analysis was not possible due to substantial heterogeneity between study protocols.

CONCLUSIONS

All studies consistently identified a proportion of hyperglycaemic hospital patients as having a diabetes-range HbA1c, showing that in-hospital blood glucose screening can facilitate diabetes diagnosis. The proportion of hyperglycaemic participants with undiagnosed diabetes varied substantially, indicating a need for further research and consistency in defining in-hospital hyperglycaemia. This may aid the development of a standardised screening protocol to identify people with possible undiagnosed diabetes.

Undiagnosed Diabetes in Patients Admitted to a Clinical Decision Unit from the Emergency Department: A Retrospective Review

Objectives Diabetes is a debilitating disease that affects the way the body uses or produces insulin. Research evaluating the usefulness in screening patients admitted to a clinical decision unit (CDU) from the emergency department (ED) has been limited. Methods A retrospective chart review of patients admitted to a CDU from the ED was performed. Patients included were > 18-year-old who were observed in the CDU, had blood glucose drawn greater than eight hours after admission, and who had not been previously diagnosed with diabetes. Age, sex, and fasting glucose level were collected. The analysis was done to evaluate the percentage of patients undiagnosed and at risk for diabetes mellitus by assessing fasting blood glucose the morning after admission. Results Study revealed that 27.8% of the patients analyzed in this study had fasting blood glucose levels meeting or exceeding the diagnostic threshold of 126 mg/dL and could potentially have undiagnosed diabetes. Conclusion Screening patients admitted to a CDU from the emergency department identified that 27.8% had fasting plasma glucose levels ≥ 126 mg/dL. Consideration should be made to obtain a fasting blood glucose level in those without a previous diagnosis of diabetes who are observed overnight in a CDU.

Metabolic syndrome and prediabetes in ndokwa community of Nigeria: preliminary study

BACKGROUND

Global prevalence of metabolic syndrome (MS) and diabetes is increasing, but the reference ranges for MS indices have yet to be established for sub-Saharan African countries. As part of the international research collaboration agenda for Prediabetes and Cardiovascular Complications Study (PACCS), a pilot study was conducted in one of the Ndokwa communities of Nigeria in 2013.

AIM

The study was to obtain preliminary indication of prevalence and reference values of MS in the rural communities of a low-mid income country.

MATERIALS AND METHODS

Seventy-four volunteer participants were recruited, after public lectures in high schools and churches in the community. Body mass index (BMI), blood pressure and waist circumference (WC), blood glucoselevel, and lipid profile were measured. Percentage prevalence MS was determined using commonest three criteria (Third Adult Treatment Panel (ATP III) 2001, International Diabetes Federation (IDF) 2005, and World Health Organization (WHO) 1999).

RESULTS

When individual indices of MS are considered separately; the males seem healthier than females. However, the prevalence of high-density lipoprotein (HDL) cholesterol was higher in males than in females. Equal 3% prevalence of MS was seen in both genders using the WHO standard. Other criteria show prevalence of 8% females and 11% males (ATP III), 5% females and 8% males (IDF 2005 European), and 14% females and 17% males (IDF 2005 Ethnic).

CONCLUSION

The prevalence of MS is higher in males than females; and relative to ATP III 2001 criteria, either the IDF 2005 European may underestimate MS, or the ethnic specific could overestimate the prevalence. Hence, it is important to define the criteria to be used.

A comparison of three different diabetes screening methods among dental patients in Turkey

OBJECTIVE

This study was conducted to describe the frequency of diabetes in dental patients, and to compare three different screening methods: the random finger plasma glucose (RFPG) test, the Finnish diabetes risk score (FINDRISC) survey and a special clinical guideline developed for dental patients.

METHODS

The study design was cross-sectional, descriptive and comparative. The data were collected between August 2011 and February 2012. A total of 702 dental patients participated in this study. The screening tools were RFPG, FINDRISC and a clinical guideline. Data were analyzed using the Chi-squared test, the t test, analysis of variance, and the Pearson correlation test.

RESULTS

The frequency of diabetes was 8.3% for the participants. The prevalence of participants at risk for undiagnosed diabetes was 20.1% according to the RFPG test, 29.9% according to the FINDRISC, and 29.8% according to the clinical guideline. Correlation analysis showed a significant positive correlation between the screening methods (p<0.001 for each).

CONCLUSION

The overall frequency of diabetes was 8.3%. It was found that the three screening methods used in this study were statistically similar. However, FINDRISC and clinical guideline as the questionnaire screening tools indicated a little larger group than RFPG with respect to diabetes risk.

Incidental findings of elevated random plasma glucose in the ED as a prompt for outpatient diabetes screening: a retrospective study

OBJECTIVE

To determine whether random plasma glucose (RPG) collected from patients without known impaired glucose metabolism (IGM) in the emergency department (ED) is a useful screen for diabetes or prediabetes.

DESIGN

Retrospective cohort study.

SETTING

ED of a Canadian teaching hospital over 1 month.

PARTICIPANTS

Adult patients in ED with RPG over 7 mmol/L were recruited for participation. Exclusion criteria included known diabetes, hospital admission and inability to consent. Participants were contacted by mail, encouraged to follow-up with their family physician (FP) for further testing and subsequently interviewed.

OUTCOME MEASURES

The primary outcome measure was the proportion of patients in the ED with RPG over 7 mmol/L and no previous diagnosis of IGM who were diagnosed with diabetes or prediabetes after secondary testing by FP with oral glucose tolerance test or fasting plasma glucose (FPG). Secondary outcomes included patient characteristics (age, gender, body mass index and language) and (2) compliance with advice to seek an appropriate follow-up care.

RESULTS

RPG was drawn on approximately one-third (33%, n=1149) of the 3470 patients in the ED in March 2010. RPG over 7 mmol/L was detected in 24% (n=278) of patients, and after first telephone follow-up, 32% (n=88/278) met the inclusion criteria and were advised to seek confirmatory testing. 41% (n=114/278) of patients were excluded for known diabetes. 73% of patients contacted (n=64/88) followed up with their FP. 12.5% (n=11/88) of patients had abnormal FPG, and of these 11% (n=10/88) were encouraged to initiate lifestyle modifications and 1% (n=1/88) was started on an oral hypoglycaemic agent. For 7% (n=6/88) of patients, FP's declined to do follow-up fasting blood work.

CONCLUSIONS

Elevated RPG in the ED is useful for identification of patients at risk for IGM and in need of further diabetic screening. Emergency physicians should advise patients with elevated RPG to consider screening for diabetes. For ED screening to be successful, patient education and collaboration with FPs are essential.

Root caries and diabetes: risk assessing to improve oral and systemic health outcomes

This report reviews the current understanding of the relationship between diabetes and root caries, and investigates the evidence for dental chairside testing of gingival crevicular blood (GCB) glucose levels to assess risk for type 2 diabetes mellitus. Diabetes is linked with the progression of periodontal disease and a greater number of exposed root surfaces at risk for root caries. The rapidly increasing prevalence of type 2 diabetes coupled with a general trend towards retention of teeth means that the number of patients with increased risk for root caries is expanding significantly. Many patients with diabetes or abnormal blood glucose levels are unaware of their condition or that they are at increased risk for oral disease. Systemic blood glucose concentrations are comparable to those found in GCB and therefore may be a useful adjunctive clinical aid in determining appropriate care for patients and providing timely referrals to general medical practitioners. Use of GCB testing within the dental clinic is described. It is proposed that future studies be undertaken to provide clinicians with improved risk assessment strategies and to evaluate GCB glucose screening models.
