Impact of Medication Adherence and Persistence on Clinical and Economic Outcomes in Patients with Type 2 Diabetes Treated with Liraglutide: A Retrospective Cohort Study
Smoking cessation in adults with diabetes: a systematic review and meta-analysis of data from randomised controlled trials.
OBJECTIVES: To evaluate the effects of more intensive smoking cessation interventions compared to less intensive interventions on smoking cessation in people with type 1 or type 2 diabetes. DESIGN: A systematic review and meta-analysis of randomised trials of smoking cessation interventions was conducted. Electronic searches were carried out on the following databases: MEDLINE, EMBASE, CINAHL and PsycINFO to September 2013. Searches were supplemented by review of trial registries and references from identified trials. Citations and full-text articles were screened by two reviewers. A random-effect Mantel-Haenszel model was used to pool data. SETTING: Primary, secondary and tertiary care. PARTICIPANTS: Adults with type 1 or type 2 diabetes. INTERVENTIONS: Smoking cessation interventions or medication (more intensive interventions) compared to usual care, counselling or optional medication (less intensive interventions). OUTCOME MEASURES: Biochemically verified smoking cessation was the primary outcome. Secondary outcomes were adverse events and effects on glycaemic control. We also carried out a pooled analysis of self-reported smoking cessation outcomes. RESULTS: We screened 1783 citations and reviewed seven articles reporting eight trials in 872 participants. All trials were of 6 months duration. Three trials included pharmacotherapy for smoking cessation. The risk ratio of biochemically verified smoking cessation was 1.32 (95% CI 0.23 to 7.43) for the more intensive interventions compared to less intensive interventions with significant heterogeneity (I(2)=76%). Only one trial reported measures of glycaemic control. CONCLUSIONS: There is an absence of evidence of efficacy for more intensive smoking cessation interventions in people with diabetes. The more intensive strategies tested in trials to date include interventions used in the general population, adding in diabetes-specific education about increased risk. Future research should focus on multicomponent smoking cessation interventions carried out over a period of at least 1 year, and also assess impact on glycaemic control

Predictors of suboptimal glycaemic control in type 2 diabetes patients: The role of medication adherence and body mass index in the relationship between glycaemia and age
Aims: To analyse predictors of glycaemic control including medication adherence and body mass index (BMI) in UK general practice patients with sub-optimally controlled type 2 diabetes. Methods: Baseline demographic, health- and treatment-related measures were evaluated as predictors of one year glycaemic control defined separately as HbA 1c≤7.5% and a continuous measure of HbA 1c concentration, using multivariate regression models. Significant predictors were adjusted for objectively assessed medication adherence and BMI. Results: One-year HbA 1c concentration was associated with baseline HbA 1c (p<0.001), BMI (p=0.02), and inversely associated with age (p=0.007) and objectively assessed adherence. Adherent patients had one-year (adjusted) HbA 1c concentration 0.65% (95% CI -1.04, -0.25; p=0.001) lower than nonadherent. Odds ratios (95% CI) of HbA 1c≤7.5% for 10-year higher age were 1.63 (1.08, 2.45); for adherent compared to non-adherent patients 1.89 (0.84, 4.25); for patients receiving >5 compared to ≤5 medications 0.32 (0.13, 0.76); and for each 1% increment in baseline HbA 1c 0.48 (0.31, 0.73). Conclusions: The lower HbA 1c achieved from greater adherence to glucose lowering treatment is comparable to that achieved with additional medication. Relationships between older age and better glycaemic control are not explained by better adherence, but may partly relate to lower BMI. © 2011 Elsevier Ireland Ltd
Diagnostic accuracy of urine dipstick testing in screening for microalbuminuria in type 2 diabetes: a cohort study in primary care.
BACKGROUND: Clinical guidelines recommend annual screening for microalbuminuria in diabetes. Detection of microalbuminuria is important because it is associated with increased morbidity and mortality. Dipstick tests for microalbuminuria may be convenient, but their accuracy is uncertain. OBJECTIVE: To assess the utility of urine dipstick testing for microalbuminuria in type 2 diabetes. METHODS: In a 6-week cohort study in four general practices in Oxfordshire, UK, first-pass urine samples were obtained at two weekly intervals from patients with type 2 diabetes and tested in the practice using Micral-Test and Microalbustix urine dipsticks. Parallel samples were sent for laboratory albumin-creatinine ratio (ACR) assay. Results of single dipstick tests and sequences of dipstick and laboratory tests were compared with a clinical testing strategy based on current guidelines to assess the accuracy and estimate costs of testing. RESULTS: The prevalence of microalbuminuria was 12.5% (n = 88). Mean (standard deviation) age was 68 (10) years, 56 (57%) were men. Median (interquartile range) diabetes duration was 6.2 (2.0-10.0) years. The sensitivity and specificity, respectively, of a single Micral-Test were 91.7% and 44.0% and of a Microalbustix test 33.3% and 92.0%. Testing strategies involving dipstick and laboratory ACR measurements or dipstick tests had similar accuracy. The costs of using dipstick tests were overall lower than laboratory ACR-based testing. CONCLUSIONS: Dipstick testing in this study did not reliably identify diabetes patients with microalbuminuria. Although dipstick testing would decrease testing costs, it could either fail to diagnose most patients with microalbuminuria or increase the numbers of patients retested depending on the dipstick used
Stepwise self-titration of oral glucose-lowering medication using a mobile telephone-based telehealth platform in type 2 diabetes: a feasibility trial in primary care.
BACKGROUND: Telehealth-supported clinical interventions may improve diabetes self-management. We explored the feasibility of stepwise self-titration of oral glucose-lowering medication guided by a mobile telephone-based telehealth platform for improving glycemic control in type 2 diabetes. METHODS: We recruited 14 type 2 diabetes patients to a one-year feasibility study with 1:1 randomization. Intervention group patients followed a stepwise treatment plan for titration of oral glucose-lowering medication with self-monitoring of glycemia using real-time graphical feedback on a mobile telephone and remote nurse monitoring using a Web-based tool. We carried out an interim analysis at 6 months. RESULTS: We screened 3476 type 2 diabetes patients; 94% of the ineligible did not meet the eligibility criteria for hemoglobin A1c (HbA1c) or current treatment. Mean (standard deviation) patient age at baseline was 58 (11) years, HbA1c was 65 (12) mmol/mol (8.1% [1.1%]), body mass index was 32.9 (6.4) kg/m2, median [interquartile range (IQR)] diabetes duration was 2.6 (0.6 to 4.7) years, and 10 (71%) were men. The median (IQR) change in HbA1c from baseline to six months was -10 (-21 to 3) mmol/mol (-0.9% [-1.9% to 0%]) in the intervention group and -5 (-13 to 6) mmol/mol (-0.5% [-1.2% to 0.6%]) in the control group. Six out of seven intervention group patients and four out of seven control group patients changed their oral glucose-lowering medication (p = .24). CONCLUSIONS: Self-titration of oral glucose-lowering medication in type 2 diabetes with self-monitoring and remote monitoring of glycemia is feasible, and further studies using adapted recruitment strategies are required to evaluate whether it improves clinical outcomes
