[PMID: 30072234 DOI: 10.1016/s2213-8587(18)30074-3] [Citation(s) in RCA: 44] [Impact Index Per Article: 8.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/20/2017] [Revised: 02/13/2018] [Accepted: 02/20/2018] [Indexed: 12/23/2022]
Abstract
Blood glucose meters and test strips for self-monitoring of blood glucose (SMBG) are often inaccessible to, and infrequently used by, people with diabetes in countries with limited resources for health care. Supplies for measuring blood glucose can also be scarce in health facilities, despite being needed in a myriad of clinical settings at all levels of the health system. Numerous studies and international guidelines emphasise the value of SMBG in diabetes care, particularly in people with type 1 diabetes. In this Review, we assess global access to blood glucose meters and test strips, collating published information on cost, availability, system accuracy, competitive bidding, technological trends, and non-financial barriers. We also provide new information on global market share data and prices, taxes and tariffs, and product availability. Blood glucose meters and test strips should be viewed similarly to essential medicines, with issues of access prioritised by relevant international agencies. Efforts are needed to reduce tariffs and taxes and to create unified global system accuracy requirements and accountable post-marketing evaluations. Preferential pricing arrangements, pooled procurement, and best-purchasing practices could help to lower direct costs. SMBG supplies should also be included in national health insurance schemes. Enhanced diabetes education of health professionals and patients is crucial to ensure effective use of SMBG. Finally, as technology advances for people who can afford new interstitial fluid glucose monitoring systems, blood glucose meters and test strips must remain available and become more affordable in low-resource settings.

Hellmund R, Weitgasser R, Blissett D. Cost Calculation for a Flash Glucose Monitoring System for Adults with Type 2 Diabetes Mellitus Using Intensive Insulin - a UK Perspective. EUROPEAN ENDOCRINOLOGY 2018; 14:86-92. [PMID: 30349600 PMCID: PMC6182928 DOI: 10.17925/ee.2018.14.2.86] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/11/2018] [Accepted: 07/12/2018] [Indexed: 01/28/2023]
Abstract
Aims: Estimate the costs associated with flash glucose monitoring as a replacement for routine self-monitoring of blood glucose (SMBG) in patients with type 2 diabetes mellitus (T2DM) using intensive insulin, from a UK National Health Service (NHS) perspective. Methods: The base-case cost calculation used the frequency of SMBG and healthcare resource use observed in the REPLACE trial. Scenario analyses considered SMBG at the flash monitoring frequencies observed in the REPLACE trial (8.3 tests per day) and a real-world analysis (16 tests per day). Results: Compared with 3 SMBG tests per day, flash monitoring would cost an additional £585 per patient per year, offset by a £776 reduction in healthcare resource use, based on reductions in emergency room visits (41%), ambulance call-outs (66%) and hospital admissions (77%) observed in the REPLACE trial. Per patient, the estimated total annual cost for flash monitoring was £191 (13.4%) lower than for SMBG. In the scenarios based on acquisition cost alone, flash monitoring was cost-neutral versus 8.3 SMBG tests per day (5% decrease) and cost-saving at higher testing frequencies. Conclusion: From a UK NHS perspective, for patients with T2DM using intensive insulin, flash monitoring is potentially cost-saving compared with routine SMBG irrespective of testing frequency.

The Cost-effectiveness of a Flash Glucose Monitoring System for Management of Patients with Type 2 Diabetes Receiving Intensive Insulin Treatment in Sweden. EUROPEAN ENDOCRINOLOGY 2018; 14:80-85. [PMID: 30349599 PMCID: PMC6182927 DOI: 10.17925/ee.2018.14.2.80] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/12/2018] [Accepted: 08/07/2018] [Indexed: 01/04/2023]
Abstract
Flash glucose monitoring, an alternative to traditional self-monitoring of blood glucose (SMBG), prevents hypoglycaemic events without impacting glycated haemoglobin (REPLACE trial). Given the potential benefits, this study assessed the cost-effectiveness of using flash monitoring versus SMBG alone in patients with type 2 diabetes (T2D) receiving intensive insulin treatment in Sweden.Methods: This study used the IQVIA CORE Diabetes Model (IQVIA CDM, v8.5) to simulate the impact of flash monitoring versus SMBG over 40 years from the Swedish societal perspective. Baseline characteristics, intervention effects, and resource utilisation were derived from REPLACE; literature and Tandvårds-Läkemedelförmånsverket (TLV) sources informed utilities and costs. Scenario analyses explored the effect of key base case assumptions. Results: In base case analysis, direct medical costs for flash monitoring use were SEK1,630,586 (€158,523) versus SEK1,459,394 (€141,902) for SMBG use. Flash monitoring led to 0.56 additional quality-adjusted life years (QALYs; 6.21 versus 5.65 SMBG) for an incremental cost-effectiveness ratio (ICER) of SEK306,082/QALY (€29,762/QALY). ICERs for all scenarios remained under SEK400,000/QALY (€38,894/QALY). Conclusions: Hypoglycaemia and health utility benefits due to flash glucose monitoring may translate into economic value compared to SMBG. With robust results across scenario analyses, flash monitoring may be considered cost-effective in a Swedish population of T2D intensive insulin users.

Can J Diabetes 2017; 42:5-10. [PMID: 28499790 DOI: 10.1016/j.jcjd.2017.01.004] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/15/2016] [Revised: 01/09/2017] [Accepted: 01/09/2017] [Indexed: 11/28/2022]
Abstract
OBJECTIVES To describe trends in blood glucose test strip (TS) utilization and cost in Saskatchewan. METHODS A retrospective analysis of TS use between January 1, 1996, and December 31, 2013, was conducted using population-based health administrative databases in Saskatchewan. The prescription drug database was used to describe the annual number of TS dispensations, the number of strips dispensed, the number of unique beneficiaries and the total costs. A patient-level analysis was also carried out to describe the patterns of TS use (i.e. light, moderate or heavy) by the entire cohort and by diabetes treatments. Potential cost savings due to a newly implemented restriction policy were estimated based on the most recent data (2013). RESULTS TS utilization increased dramatically between 1996 and 2013 in terms of the number of users and the average number of TSs received. The percentage of TS users receiving fewer than 4 TSs per week (i.e. light users) decreased by 20%, while the percentage of heavy users (i.e. those receiving more than 8 TSs per week) increased by 19%. During the same period, the use of high-risk oral hypoglycemic medications declined by 30% among all TS users. Heavy TS use was observed in at least one-third of all users, irrespective of treatment type. CONCLUSIONS If Saskatchewan's newly imposed coverage limits had been applied in 2013, the costs of strips exceeding those limits would have totalled $2.5 million. Although TS use aligns with chronic disease care paradigms, the substantial costs and lack of evidence of patient outcomes demand better strategies to help reduce unnecessary use.

Abstract
OBJECTIVES Considerable attention has been paid to the rising costs of the use of blood glucose test strips (BGTS). Insulin users have generally been treated as a single homogeneous group, resulting in policies that cap usage (8.2 strips/day) in provincial drug insurance programs. The objective of this study was to conduct a utilization review of BGTS by insulin users and to evaluate use patterns against current insulin use patterns and BGTS policy. METHODS BGTS usage was examined in a cohort of insulin users with type 1 and type 2 diabetes over a 12-year period (2001 to 2013) using the population-based administrative data in Manitoba, Canada. RESULTS Total BGTS strip use increased by 121%, from $4.3 to $9.5 million. However, the number of insulin users also increased by 115%. Use has been stable at 1.5 strips per day per person since 2004 by insulin users with type 2 diabetes but has risen from 1.9 to 3.0 strips per day per person in those with type 1 diabetes. Mean daily test strip use was below the number of daily tests recommended for patients using insulin as per the current Canadian guidelines, with 11% and 15% of insulin users with type 1 and type 2 diabetes not claiming any BGTS use and a further 15% (type 1) and 28% (type 2) using fewer than 1 strip per day. CONCLUSIONS BGTS use per insulin user has been stable for most of the past decade, and the vast majority of use falls well below provincial insurance caps. The amount of low-level testing (0 to <1 strip/day) suggests that greater attention should be directed to ensuring a safe level of testing by all insulin users.

Abstract
AIMS To compare the efficacy and safety of two titration algorithms for insulin degludec/insulin aspart (IDegAsp) administered once daily with metformin in participants with insulin-naïve Type 2 diabetes mellitus. METHODS This open-label, parallel-group, 26-week, multicentre, treat-to-target trial, randomly allocated participants (1:1) to two titration arms. The Simple algorithm titrated IDegAsp twice weekly based on a single pre-breakfast self-monitored plasma glucose (SMPG) measurement. The Stepwise algorithm titrated IDegAsp once weekly based on the lowest of three consecutive pre-breakfast SMPG measurements. In both groups, IDegAsp once daily was titrated to pre-breakfast plasma glucose values of 4.0-5.0 mmol/l. Primary endpoint was change from baseline in HbA1c (%) after 26 weeks. RESULTS Change in HbA1c at Week 26 was IDegAspSimple -14.6 mmol/mol (-1.3%) (to 52.4 mmol/mol; 6.9%) and IDegAspStepwise -11.9 mmol/mol (-1.1%) (to 54.7 mmol/mol; 7.2%). The estimated between-group treatment difference was -1.97 mmol/mol [95% confidence interval (CI) -4.1, 0.2] (-0.2%, 95% CI -0.4, 0.02), confirming the non-inferiority of IDegAspSimple to IDegAspStepwise (non-inferiority limit of ≤ 0.4%). Mean reduction in fasting plasma glucose and 8-point SMPG profiles were similar between groups. Rates of confirmed hypoglycaemia were lower for IDegAspStepwise [2.1 per patient years of exposure (PYE)] vs. IDegAspSimple (3.3 PYE) (estimated rate ratio IDegAspSimple /IDegAspStepwise 1.8; 95% CI 1.1, 2.9). Nocturnal hypoglycaemia rates were similar between groups. No severe hypoglycaemic events were reported. CONCLUSIONS In participants with insulin-naïve Type 2 diabetes mellitus, the IDegAspSimple titration algorithm improved HbA1c levels as effectively as a Stepwise titration algorithm. Hypoglycaemia rates were lower in the Stepwise arm.

Abstract
OBJECTIVE To assess the relationship between metabolic control (MC) and frequency of self-monitoring of blood glucose (SMBG) in insulin-treated patients with type 1 (T1DM) and type 2 (T2DM) diabetes mellitus, and to analyze the factors associated to MC. MATERIAL AND METHODS A multicenter, cross-sectional, observational study was conducted in which endocrinologists enrolled diabetic patients treated with insulin who used a glucometer. The cut-off value for MC was HbA1c ≤ 7%. Grade of acceptance of the glucometer was assessed using a visual analogue scale (VAS). RESULTS A total of 341 patients (53.5% males) with a mean age (SD) 52.8 (16.3) years, mean HbA1c of 7.69% (1.25) and 128 (37.5%) with T1DM and 211 (61.9%) with T2DM were evaluable. SMBG was done by 86.1% at least once weekly. No relationship was seen between MC and SMBG (P=.678) in the overall sample or in the T1DM (P=.940) or T2DM (P=.343) subgroups. In the logistic regression model, hyperglycemic episodes (Exp-b [risk] 1.794, P=0.022), falsely elevated HbA1c values (Exp-b 3.182, P=.005), and VAS (Exp-b 1.269, P=.008) were associated to poor MC in the total sample. Hyperglycemic episodes (Exp-b 2.538, P=.004), falsely elevated HbA1c values (Exp-b 3.125, P=.012), and VAS (Exp-b 1.316, P=.026) were associated to poor MC in the T2DM subgroup, while body mass index (Exp-b 1.143, P=.046) was associated to poor MC in the T1DM subgroup. CONCLUSIONS In this retrospective, non-controlled study on patients with DM treated with insulin who used a glucometer, no relationship was seen between the degree of metabolic control and frequency of use of the glucometer.

Abstract
BACKGROUND Through a retrospective database analysis, this study seeks to provide an understanding of the utilization of SMBG by insulin therapy and diabetes type and to estimate healthcare costs of blood glucose monitoring in the UK diabetes population. METHODS Data were obtained from the IMS LifeLink Electronic Medical Record-Europe (EMR-EU) Database, a longitudinal database containing anonymized patient records from physician-practice data systems of office-based physicians in the UK. Depending on the insulin types used for type 1 and type 2 diabetes, patients were sub-categorized into one of four insulin regimen groups (basal, bolus, pre-mixed, or basal-bolus). Frequency of blood glucose testing was assessed descriptively throughout the 12-month post-index period, and generalized linear models were used to evaluate the effect of baseline characteristics, including insulin type, on the likelihood of blood glucose test utilization. Healthcare resource utilization and costs for all-cause services were assessed by insulin type. RESULTS This study identified 8322 type 1 and type 2 diabetes patients with two insulin pharmacy records between January 1, 2009 and December 31, 2010. After applying study inclusion and exclusion criteria, a total of 2676 (32.2%) insulin-treated diabetes mellitus patients in the UK were identified, with the number of pharmacy blood glucose test strips averaging 771.1 (median 600). The glucose testing frequency was lowest among basal-only insulin patients and pre-mixed insulin patients (mean=576.2 [median=450] and mean=599.5 [median=500], respectively; non-significantly different) compared to other insulin types. CONCLUSION Although the data did not capture the glucose frequency comprehensively, it varied significantly by insulin types, and was higher than what is recommended in the guidelines for patients with type 2 diabetes.

Abstract
PURPOSE People with insulin-treated diabetes often face strict regimens with inflexible dose timing, frequent injections, and frequent self-measured blood glucose (SMBG) testing. The objective of this study was to estimate the health-related quality-of-life (HRQoL) impact of these aspects using time trade-off (TTO) methods. METHODS HRQoL was examined via a TTO survey in the UK, Canada, and Sweden with separate analyses of 2465 respondents from the general population, 274 people with type 1 diabetes, and 417 people with type 2 diabetes. Respondents evaluated health states with diabetes, SMBG testing, and basal injections that were once-daily time flexible, once-daily at a fixed time, and twice-daily at a fixed time in a basal or basal-bolus regimen. RESULTS Time-flexible basal injections were associated with 0.016 and 0.013 higher utility vs a fixed time of injection for basal-only and basal-bolus regimens, respectively, as evaluated by the general population. The diabetes respondents confirmed the basal-only results with 0.015 higher utility, but the difference in utility was non-significant for basal-bolus. Once-daily injections had higher utility compared with twice-daily injections for basal (0.039 and 0.042) and basal-bolus (0.022 and 0.021) regimens, as evaluated by the general population and people with diabetes, respectively. Increased frequency of SMBG negatively affected health utility. LIMITATIONS This study has the limitation that it measures hypothetical health states rather than the HRQoL of people with these health states; furthermore, it could be suggested that the web-based nature of this survey is biased towards literate respondents with internet access and IT competence. CONCLUSIONS Flexible dosing and fewer injections have a positive HRQoL impact, which potentially may enhance therapy adherence and could contribute to improved long-term outcomes. The impact of flexibility is greater in people treated with basal-only insulin regimens, and diminishes if bolus injections are part of the treatment regimen.

Abstract
BACKGROUND In patients with type 2 diabetes mellitus, basal-bolus strategies can improve treatment by offering dosing flexibility, and improved satisfaction, adherence, and clinical outcomes. The purpose of this study was to compare real-world outcomes between US patients initiating analog insulin therapy with insulin glargine and those initiating with a premixed analog insulin (PMX). METHODS This was a retrospective study of data from patients (≥18 years) with type 2 diabetes mellitus in the IMPACT® database who initiated insulin treatment with insulin glargine (GLA) or a PMX. Clinical and economic outcomes were measured over one year, including persistence and adherence, consumption of insulin, glycemic outcomes, incident hypoglycemia, and health care resource utilization and cost. RESULTS Data from 2,502 patients were included in the analyses (n = 834 for PMX, n = 1,668 for GLA). Compared with PMX, persistence was higher and consumption of insulin was lower for GLA (both P < 0.0001). Adherence, glycemic outcomes, and hypoglycemia-related events were similar between groups, as were health care utilization and total health care costs. Diabetes-related drug and supply costs were lower for GLA than for PMX (P < 0.0001 and P = 0.046, respectively). CONCLUSION In US patients with type 2 diabetes mellitus, initiating insulin with once-daily GLA, rather than a PMX, is associated with increased treatment persistence and similar clinical and hypoglycemic outcomes, but lower diabetes pharmacy and supply costs. GLA may be a more flexible option than PMX. However, these results also show suboptimal glycemic control in the real-world setting despite change in treatment regimens and call for optimization in management of patients with type 2 diabetes mellitus.

Abstract
INTRODUCTION Insulin degludec (IDeg) is a new basal insulin in development with a flat, ultra-long action profile that may permit dosing using a simplified titration algorithm with less frequent self-measured blood glucose (SMBG) measurements and more simplified titration steps than currently available basal insulins. METHODS This 26-week, multi-center, open-label, randomized, treat-to-target study compared the efficacy and safety of IDeg administered once-daily in combination with metformin in insulin-naïve subjects with type 2 diabetes using two different patient-driven titration algorithms: a "Simple" algorithm, with dose adjustments based on one pre-breakfast SMBG measurement (n = 111) versus a "Step-wise" algorithm, with adjustments based on three consecutive pre-breakfast SMBG values (n = 111). IDeg was administered using the FlexTouch® insulin pen (Novo Nordisk A/S, Bagsværd, Denmark), with once-weekly dose titration in both groups. RESULTS Glycosylated hemoglobin (HbA1c) decreased from baseline to week 26 in both groups (-1.09%, IDegSimple; -0.93%, IDegStep-wise). IDegSimple was non-inferior to IDegStep-wise in lowering HbA1c [estimated treatment difference (IDegSimple - IDegStep-wise): -0.16% points (-0.39; 0.07)95% CI]. Fasting plasma glucose was reduced (-3.27 mmol/L, IDegSimple; -2.68 mmol/L, IDegStep-wise) with no significant difference between groups. Rates of confirmed hypoglycemia [1.60, IDegSimple; 1.17, IDegStep-wise events/patient year of exposure (PYE)] and nocturnal confirmed hypoglycemia (0.21, IDegSimple; 0.10, IDegStep-wise events/PYE) were low, with no significant differences between groups. Daily insulin dose after 26 weeks was 0.61 U/kg (IDegSimple) and 0.50 U/kg (IDegStep-wise). No significant difference in weight change was seen between groups by week 26 (+1.6 kg, IDegSimple; +1.1 kg, IDegStep-wise), and there were no clinically relevant differences in adverse event profiles. CONCLUSION IDeg was effective and well tolerated using either the Simple or Step-wise titration algorithm. While selection of an algorithm must be based on individual patient characteristics and goals, the ability to attain good glycemic control using a simplified titration algorithm may enable patient empowerment through self-titration, improved convenience, and reduced costs.

Reformulation of controlled-release oxycodone and pharmacy dispensing patterns near the US-Canada border. OPEN MEDICINE : A PEER-REVIEWED, INDEPENDENT, OPEN-ACCESS JOURNAL 2012; 6:e141-5. [PMID: 23687529 PMCID: PMC3654510] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 09/25/2012] [Revised: 11/05/2012] [Accepted: 11/05/2012] [Indexed: 11/18/2022]
Abstract
BACKGROUND In August 2010, a tamper-resistant formulation of controlled-release oxycodone (OxyContin-OP) was introduced in the United States but not in Canada. Our objective was to determine whether introduction of OxyContin-OP in the United States influenced prescription volumes for the original controlled-release oxycodone formulation (OxyContin) at Canadian pharmacies near the international border. METHODS We conducted a population-based, serial, cross-sectional study of prescriptions dispensed from pharmacies in the 3 cities with the highest volume of US-Canada border crossings in Ontario: Niagara Falls, Windsor and Sarnia. We analyzed data on all outpatient prescriptions for OxyContin dispensed by Canadian pharmacies near each border crossing between 2010 Apr. 1 and 2012 Feb. 29. We calculated and compared monthly prescription rates, adjusted per 1000 population and stratified by tablet strength. RESULTS The number of tablets dispensed near 4 border crossings in the 3 Canadian cities remained stable over the study period. However, the rate of dispensing at pharmacies near the Detroit-Windsor Tunnel increased roughly 4-fold between August 2010 and February 2011, from 505 to 1969 tablets per 1000 population. By April 2011, following warnings to prescribers and pharmacies regarding drug-seeking behaviour, the dispensing rate declined to 1683 tablets per 1000 population in this area. By November 2011, the rate had returned to levels observed in early 2010. Our analyses suggest that 242 075 excess OxyContin tablets were dispensed near the Detroit-Windsor Tunnel between August 2010 and October 2011. CONCLUSIONS Prescribing of the original formulation of controlled-release oxycodone rose substantially near a major international border crossing following the introduction of a tamper-resistant formulation in the United States. It is possible that the restriction of this finding to the area surrounding the Detroit-Windsor Tunnel reflects specific characteristics of this border crossing, including its high traffic volume, direct access to the downtown core and drug-trafficking patterns in the Detroit area. Our findings highlight the potential impact of cross-border differences in medication availability on drug-seeking behaviour.
