    Input: OBJECTIVE To assess the effectiveness of structured blood glucose testing in poorly controlled , noninsulin-treated type 2 diabetes . RESEARCH DESIGN AND METHODS This 12-month , prospect i ve , cluster-r and omized , multicenter study recruited 483 poorly controlled ( A1C ≥7.5 % ) , insulin-naïve type 2 diabetic subjects from 34 primary care practice s in the U.S. Practice s were r and omized to an active control group ( ACG ) with enhanced usual care or a structured testing group ( STG ) with enhanced usual care and at least quarterly use of structured self-monitoring of blood glucose ( SMBG ) . STG patients and physicians were trained to use a paper tool to collect/interpret 7-point glucose profiles over 3 consecutive days . The primary end point was A1C level measured at 12 months . RESULTS The 12-month intent-to-treat analysis ( ACG , n = 227 ; STG , n = 256 ) showed significantly greater reductions in mean ( SE ) A1C in the STG compared with the ACG : −1.2 % ( 0.09 ) vs. −0.9 % ( 0.10 ) ; Δ = −0.3 % ; P = 0.04 . Per protocol analysis ( ACG , n = 161 ; STG , n = 130 ) showed even greater mean ( SE ) A1C reductions in the STG compared with the ACG : −1.3 % ( 0.11 ) vs. −0.8 % ( 0.11 ) ; Δ = −0.5 % ; P < 0.003 . Significantly more STG patients received a treatment change recommendation at the month 1 visit compared with ACG patients , regardless of the patient ’s initial baseline A1C level : 179 ( 75.5 % ) vs. 61 ( 28.0 % ) ; < 0.0001 . Both STG and ACG patients displayed significant ( P < 0.0001 ) improvements in general well-being ( GWB ) . CONCLUSIONS Appropriate use of structured SMBG significantly improves glycemic control and facilitates more timely/aggressive treatment changes in noninsulin-treated type 2 diabetes without decreasing GWB Objectives To assess the effect of self monitoring of blood glucose concentrations on glycaemic control and psychological indices in patients with newly diagnosed type 2 diabetes mellitus . Design Prospect i ve r and omised controlled trial of self monitoring versus no monitoring ( control ) . Setting Hospital diabetes clinics . Participants 184 ( 111 men ) people aged < 70 with newly diagnosed type 2 diabetes referred to the participating diabetes clinics . Major exclusion criteria were secondary diabetes , insulin treatment , previous self monitoring of blood glucose . Interventions Participants were r and omised to self monitoring or no monitoring ( control ) groups for one year with follow-up at three monthly intervals . Both groups underwent an identical structured core education programme . The self monitoring group received additional education on monitoring . Main outcome measures Between group differences in HbA1c , psychological indices , use of oral hypoglycaemic drugs , body mass index ( BMI ) , and reported hypoglycaemia rates . Results 96 patients ( 55 men ) were r and omised to monitoring and 88 ( 56 men ) to control . There were no baseline differences in mean ( SD ) age ( 57.7 ( 11.0 ) in monitoring group v 60.9 ( 11.5 ) in control group ) or HbA1c ( 8.8 (2.1)% v 8.6 (2.3)% , respectively ) . Those in the monitoring group had a higher baseline BMI ( 34 ( 7 ) v 32 ( 6.2 ) ) . There were no significant differences between groups at any time point ( 12 months values given ) in HbA1c ( 6.9 (0.8)% v 6.9 (1.2)% , P=0.69 ; 95 % confidence interval for difference −0.25 % to 0.38 % ) , BMI ( 33.1 ( 6.4 ) v 31.8 ( 6.0 ) ; adjusted for baseline BMI , P=0.32 ) , use of oral hypoglycaemic drugs , or reported incidence of hypoglycaemia . Monitoring was associated with a 6 % higher score on the depression subscale of the well-being question naire ( P=0.01 ) . Conclusions In patients with newly diagnosed type 2 diabetes self monitoring of blood glucose concentration has no effect on glycaemic control but is associated with higher scores on a depression subscale . Trial registration IS RCT N 49814766 OBJECTIVE To investigate the effect of meal-related self-monitoring of blood glucose on glycemic control and well-being in non-insulin-treated type 2 diabetic patients . RESEARCH DESIGN AND METHODS This 6-month study , which included 6 months of follow-up , adopted a prospect i ve , multicenter , r and omized controlled design . Subjects were r and omized to two groups : one group used a blood glucose-monitoring device , kept a blood glucose/eating diary , and received st and ardized counseling ; the control group received nonst and ardized counseling on diet and lifestyle . The primary efficacy parameter was the change in HbA(1c ) . Secondary efficacy variables included changes in body weight , lipids , and microalbumin and changes in treatment satisfaction and well-being . RESULTS In the per- protocol analysis , the use of a self-monitoring blood glucose device significantly reduced HbA(1c ) levels by 1.0 + /- 1.08 % compared with 0.54 + /- 1.41 % for the control group ( P = 0.0086 ) ; subgroup analysis showed three types of responders . Body weight , total cholesterol , and microalbumin improved when using a glucometer , but there was no statistically significant difference between the two groups . Treatment satisfaction increased in both groups to a similar extent ( P = 0.9 ) . Self-monitoring result ed in a marked improvement of general well-being with significant improvements in the subitems depression ( P = 0.032 ) and lack of well-being ( P = 0.02 ) . CONCLUSIONS Meal-related self-monitoring of blood glucose within a structured counseling program improved glycemic control in the majority of non-insulin-treated type 2 diabetic patients in this study . The finding of three types of responders will be important for future planning of counseling and educational interventions AIM To determine if therapeutic management programmes for type 2 diabetes that include self-monitoring of blood glucose ( SMBG ) result in greater reductions in glycated haemoglobin ( HbA1c ) compared with programmes without SMBG in non-insulin requiring patients . METHODS Multicentre , r and omized , parallel-group trial . A total of 610 patients were r and omized to SMBG or non-SMBG groups . Patients in both groups received the same oral antidiabetic therapy using a gliclazide modified release (MR)-based regimen for 27 weeks . The primary efficacy end-point was the difference between groups in HbA1c at the end of observation . RESULTS A total of 610 patients were r and omized : 311 to the SMBG group and 299 to the non-SMBG group .  HbA1c decreased from 8.12 to 6.95 % in the SMBG group and from 8.12 to 7.20 % in the non-SMBG group ; between-group difference was 0.25 % ( 95 % CI : 0.06 , 1.03 ; p = 0.0097 ) . Symptoms suggestive of mild to moderate hypoglycaemia was the most commonly reported adverse event , reported by 27 ( 8.7 % ) and 21 ( 7.0 % ) patients in the SMBG and non-SMBG groups , respectively ; the incidence of symptomatic hypoglycaemia was lower in the SMBG group . CONCLUSION In patients with type 2 diabetes , the application of SMBG as an adjunct to oral antidiabetic agent therapy results in further reductions in HbA1c Objective To determine whether self monitoring , alone or with instruction in incorporating the results into self care , is more effective than usual care in improving glycaemic control in non-insulin treated patients with type 2 diabetes . Design Three arm , open , parallel group r and omised trial . Setting 48 general practice s in Oxfordshire and South Yorkshire . Participants 453 patients with non-insulin treated type 2 diabetes ( mean age 65.7 years ) for a median duration of three years and a mean haemoglobin A1c level of 7.5 % . Interventions St and ardised usual care with measurements of HbA1c every three months as the control group ( n=152 ) , blood glucose self monitoring with advice for patients to contact their doctor for interpretation of results , in addition to usual care ( n=150 ) , and blood glucose self monitoring with additional training of patients in interpretation and application of the results to enhance motivation and maintain adherence to a healthy lifestyle ( n=151 ) . Main outcome measure HbA1c level measured at 12 months . Results At 12 months the differences in HbA1c level between the three groups ( adjusted for baseline HbA1c level ) were not statistically significant ( P=0.12 ) . The difference in unadjusted mean change in HbA1c level from baseline to 12 months between the control and less intensive self monitoring groups was −0.14 % ( 95 % confidence interval −0.35 % to 0.07 % ) and between the control and more intensive self monitoring groups was −0.17 % ( −0.37 % to 0.03 % ) . Conclusions Evidence is not convincing of an effect of self monitoring blood glucose , with or without instruction in incorporating findings into self care , in improving glycaemic control compared with usual care in reasonably well controlled non-insulin treated patients with type 2 diabetes . Trial registration Current Controlled Trials IS RCT N47464659 The goal of this study was to compare the relative efficacy and cost of self-monitoring of blood glucose ( SMBG ) with routine urine testing in the management of patients with type II ( non-insulin-dependent ) diabetes mellitus not treated with insulin . Fifty-four patients with type II diabetes mellitus , not treated with insulin , who had inadequate glucose control on diet aloneor diet and oral hypoglycemic agents were studied . Patients performed SMBG or urine glucose testing as part of a st and ardized treatment program that also included diet and exercise counseling . During the 6-mo study , both the urine-testing and SMBG groups showed similar improvement in glycemic control ; within each group , there were significant improvements in fasting plasma glucose ( reduction of 1.4 ± 3.2 mM , P < 0.03 ) and glycosylated hemoglobin ( reduction of 2.0 ± 3.4 % , P < 0.01 ) levels . Seventeen ( 31 % ) of54 patients actually normalized their glycosylated hemoglobin values , 9 in the urine-testing group and 8 in the SMBG group . Comparisons between the urine-testing and SMBG groups showed no significant differences in mean fasting plasma glucose ( P > 0.86 ) , glycosylated hemoglobin ( P > 0.95 ) , or weight ( P < 0.19 ) . In patients with type II diabetes mellitus not treated with insulin , SMBG is no more effective , but is 8–12 times more expensive , thanurine testing in facilitating improved glycemic control . Our results do not support widespread use of SMBG in diabetic patients not treated with insulin A diabetes protocol characterized by self-monitoring of blood glucose was introduced in four general practice s with the aim of making the frequency of consultations dependent on the metabolic regulation and emphasizing body weight reduction . The feasibility of the programme was investigated and the results after 1 year were compared with those of conventional care in four control practice s. In the experimental practice s , 13 patients switched from a medical specialist 's to a general practitioner 's supervision  , 20 remained under supervision of their GP  and 33 started self-monitoring .  The self-monitoring rate , the consultation frequency according to protocol , the low number of dropouts and inadequate referrals and adherence to the therapeutic scheme showed that the protocol was feasible for both the GPs and the patients . At the initial assessment , the regulation of the diabetes was worse in patients of the experimental group , compared with those of the control group ( mean HbA1 9.7 % vs 8.9 % ; p less than 0.05 ) . On average , patients in the experimental group ( n = 56 ) lost 0.4 kg of body weight , whereas those in the control group ( n = 73 ) gained 0.1 kg ( n.s . ) . The mean change in HbA1 , adjusted for the initial value , was -0.4 % in the experimental and + 0.5 % in the control group ( p less than 0.05 ) . The results of the protocol can be attributed to a combination of greater participation of the patient , the individualized consultation frequency and the prescription of oral hypoglycaemic agents according to body weight development Objective To assess the cost effectiveness of self monitoring of blood glucose alone or with additional training in incorporating the results into self 
    Output:
    
Recent evidence demonstrates that when SMBG is ' structured ' , incorporated as part of a complex intervention , and embedded within education and collaborative care , improvements in average blood glucose levels result .
In contrast , studies that do not apply SMBG systematic ally , or that assess a low frequency SMBG regimen that precludes identification and interpretation of SMBG patterns , are not clinical ly effective .
CONCLUSIONS It is the quality , not quantity , of SMBG that makes a difference to outcomes for people with non-insulin-treated T2DM .
