Quality of diabetes care in U.S. academic medical centers: low rates of medical regimen change

Individualized intensive insulin therapy of diabetes: Not only the goal, but also the time

Intensive insulin therapy has been extensively used to control blood glucose levels because of its ability to reduce the risk of chronic complications of diabetes. According to current guidelines, intensive glycemic control requires individualized glucose goals rather than as low as possible. During intensive therapy, rapid blood glucose reduction can aggravate microvascular and macrovascular complications, and prolonged overuse of insulin can lead to treatment-induced neuropathy and retinopathy, hypoglycemia, obesity, lipodystrophy, and insulin antibody syndrome. Therefore, we need to develop individualized hypoglycemic plans for patients with diabetes, including the time required for blood glucose normalization and the duration of intensive insulin therapy, which deserves further study.

A Team-based Training for Continuous Glucose Monitoring for Diabetes Care: An Implementation Pilot in Primary Care Practices (Preprint)

BACKGROUND

The American Academy of Family Physicians (AAFP) develops and maintains continuing medical education that is relevant to modern primary care practices. One continuing medical education modality is AAFP TIPS, which are comprised of resources designed for family medicine physicians and their care teams that aid in quick and accessible practice improvement strategies, with actionable steps. Evaluating physicians' use of and satisfaction with this modality's content and implementation strategies has not been prioritized previously. Continuous glucose monitoring (CGM) plays an increasing role in the treatment of diabetes; uptake occurs more rapidly in endocrinology settings than in primary care settings. To help address such differences in CGM uptake and diabetes care, AAFP TIPS on Continuous Glucose Monitoring (AAFP TIPS CGM) was developed, using published evidence and input from content experts (family medicine faculty; AAFP staff; and an advisory group comprised of other primary care physicians, patients, a pharmacist, and a primary care practice facilitator). A pilot implementation project was conducted in 3 primary care practices.

OBJECTIVE

To evaluate AAFP TIPS CGM in primary care practices, the research team assessed use of and satisfaction with the content and assessed barriers to and facilitators for strategy and workflow implementation.

METHODS

In total, 3 primary care practices participated in a mixed methods pilot implementation of AAFP TIPS CGM between June and October 2021. Practice champions at each site completed AAFP TIPS CGM and baseline practice surveys to evaluate practice characteristics and CGM prescribing. They conducted team trainings (via webinars or in person), with the goals of implementing CGM into practice and establishing or improving CGM workflows. Practice champions and team training participants completed posttraining surveys to evaluate the training, AAFP TIPS materials, and likelihood of implementing CGM. Interviews were conducted with 6 physicians, including practice champions, 2 months after team training. Satisfaction surveys were also distributed to those who completed the AAFP TIPS CGM course via the internet during the study period.

RESULTS

Of the 3 practices, 2 conducted team trainings. The team training evaluation survey showed that practice staff understood their role in implementing CGM in practice (19/20, 95%), and most (11/20, 55%) did not have questions after the training. Insurance coverage for CGM was a remaining knowledge gap and potential barrier to implementing CGM in practice. Physicians and interdisciplinary care team members who took the AAFP TIPS CGM course via the internet, as well as those who attended in-person team training, expressed a high degree of satisfaction with the education, content, and applicability of the course.

CONCLUSIONS

This pilot implementation of AAFP TIPS CGM offers pertinent and timely information for primary care practices that desire to initiate or expand CGM use to best meet the needs of their patients with diabetes.

Medication non-adherence and therapeutic inertia independently contribute to poor disease control for cardiometabolic diseases

Poorly controlled cardiometabolic biometric health gap measures [e.g.,uncontrolled blood pressure (BP), HbA1c, and low-density lipoprotein cholesterol (LDL-C)] are mediated by medication adherence and clinician-level therapeutic inertia (TI). The study of comparing relative contribution of these two factors to disease control is lacking. We conducted a retrospective cohort study using 7 years of longitudinal electronic health records (EHR) from primary care cardiometabolic patients who were 35 years or older. Cox-regression modeling was applied to estimate how baseline proportion of days covered (PDC) and TI were associated with cardiometabolic related health gap closure. 92,766 patients were included in the analysis, among which 89.9%, 85.8%, and 73.3% closed a BP, HbA1c, or LDL-C gap, respectively, with median days to gap closure ranging from 223 to 408 days. Patients who did not retrieve a medication were the least likely to achieve biometric control, particularly for LDL-C (HR = 0.58, 95% CI: 0.55-0.60). TI or uncertainty of TI was associated with a high risk of health gap persistence, particularly for LDL-C (HR ranges 0.46-0.48). Both poor medication adherence and TI are independently associated with persistent health gaps, and TI has a much higher impact on disease control compared to medication adherence, implying disease management strategies should prioritize reducing TI.

A Telehealth Diabetes Intervention for Rural Populations: Protocol for a Randomized Controlled Trial

Background

Diabetes self-management education and support (DSMES) is a crucial component of diabetes care associated with improved clinical, psychosocial, and behavioral outcomes. The American Association of Diabetes Care and Education Specialists, the American Diabetes Association, and the American Academy of Family Physicians all recommend DSMES yet accessing linguistically and culturally appropriate DSMES is challenging in rural areas. The Diabetes One-Day (D1D) program is an established DSMES group intervention that has not been adapted or evaluated in rural communities.

Objective

The specific aims of this paper are (1) to adapt the existing D1D program for use in rural communities, called rural D1D (R-D1D); and (2) to conduct a patient-level randomized controlled trial to examine the effects of R-D1D and standard patient education, guided by the Reach, Effectiveness, Adoption, Implementation, and Maintenance framework.

Methods

This is a protocol for a pilot type II hybrid implementation-effectiveness trial of a culturally adapted virtual DSMES program for rural populations, R-D1D. We will use Boot Camp Translation, a process grounded in the principles of community-based participatory research, to adapt an existing DSMES program for rural populations, in both English and Spanish. Participants at 2 rural primary care clinics (4 cohorts of N=16 plus care partners, 2 in English and 2 in Spanish) will be randomized to the intervention or standard education control. The evaluation is guided by the Reach, Effectiveness, Adoption, Implementation, and Maintenance framework. Patient-level effectiveness outcomes (hemoglobin A_1c, diabetes distress, and diabetes self-care behaviors) will be assessed using patient-reported outcomes measures and a home A_1c test kit. Practice-level and patient-level acceptability and feasibility will be assessed using surveys and interviews.

Results

This study is supported by the National Institute of Nursing. The study procedures were approved, and the adaptation processes have been completed. Recruitment and enrollment started in July 2021.

Conclusions

To our knowledge, this will be the first study to evaluate both effectiveness and implementation outcomes for virtually delivered DSMES, culturally adapted for rural populations. This research has implications for delivery to other rural locations where access to specialty diabetes care is limited.

Adjunctive Er:YAG laser in non-surgical periodontal therapy of patients with inadequately controlled type 2 diabetes mellitus: A split-mouth randomized controlled study

BACKGROUND AND OBJECTIVE

Limited studies are available comparing the outcomes of non-surgical periodontal therapy (NSPT) with or without adjunctive Er:YAG laser (ERL) in patients with type 2 diabetes mellitus (T2DM). This study evaluated the effects of ERL adjunctive NSPT on single-rooted teeth of inadequately controlled T2DM patients with periodontitis.

METHODS

Twenty-two inadequately controlled T2DM participants with periodontitis were recruited. Adopting a double-blinded split-mouth design and under block randomization, we investigated the effects of ERL in calculus removal then degranulation mode, or a sham treatment, adjunct NSPT, which included two visits of full-mouth root surface debridement delivered within 4-10 days, to test or control single-rooted teeth (Wuxi Stomatology Hospital, trial 2017-016). We followed periodontal parameters (plaque %, bleeding on probing [BOP] %, probing pocket depth [PPD], probing attachment level [PAL]) and selected systemic parameters (fasting plasma glucose [FPG], glycosylated hemoglobin [HbA1c%], high sensitivity C-reactive protein) at baseline, one, three, and six months after periodontal treatment.

RESULTS

The study was completed as planned. Periodontal parameters, FPG and HbA1c% of the 22 participants appeared significantly improved at six months (p < 0.001). The 44 ERL treated, compared to 44 sham treated single-rooted teeth exhibited significant improvement in BOP, mean PPD, and mean PAL at various postoperative follow-up time points (effect size ≥0.44; p < 0.001). No adverse event was reported.

CONCLUSION

Periodontal treatment outcomes in the T2DM patients with inadequate glycemic control were better in the single-rooted teeth received ERL adjunct NSPT. Further studies are warranted to confirm the observations reported in this short-term clinical study.

Patient-important outcomes to inform shared decision making and goal setting for diabetes treatment

OBJECTIVE

Despite well-established treatment guidelines, diabetes is difficult to manage for many individuals. The importance of using shared decision making to optimize diabetes treatment is recognized, yet what matters most to individuals with diabetes is not well established. Our goal was to identify patients' goals and priorities for diabetes management.

METHODS

We engaged 141 participants through interviews and group concept mapping to identify patient-important outcomes (PIOs) for diabetes care. We generated a master list of PIOs by aggregating interview data coded to "goals" and ideas brainstormed during concept mapping, and then a patient advisory board sorted the PIOs into higher-level domains.

RESULTS

We identified 41 PIOs sorted into 7 broad domains: optimize daily self-care, optimize long term health, learn about diabetes, achieve measurable goals, manage medications, manage diet and best utilize medical / professional services.

CONCLUSIONS

Most (4/7) of PIO domains focused on personal and life goals, not medically-oriented goals. Use of these PIOs and domains may facilitate more effective SDM discussions for patients with diabetes.

PRACTICE IMPLICATIONS

Use of PIOs from this work can enable the empowerment of patients to voice their priorities during SDM conversations, thus facilitating development of truly individualized diabetes treatment plans.

Disparities in Hemoglobin A1c Testing During the Transition to Adulthood and Association With Diabetes Outcomes in Youth-Onset Type 1 and Type 2 Diabetes: The SEARCH for Diabetes in Youth Study

OBJECTIVE

To identify correlates of hemoglobin A1c (HbA1c) testing frequency and associations with HbA1c levels and microvascular complications in youth-onset diabetes.

RESEARCH DESIGN AND METHODS

The SEARCH for Diabetes in Youth study collected data from individuals diagnosed with diabetes before age 20 at 8 years (n=1,885 type 1, n=230 type 2) and 13 years (n=649 type 1, n = 84 type 2) diabetes duration. We identified correlates of reporting ≥3 HbA1c tests/year using logistic regression. We examined associations of HbA1c testing with HbA1c levels and microvascular complications (retinopathy, neuropathy, or nephropathy) using sequentially adjusted linear and logistic regression.

RESULTS

For type 1 diabetes, odds of reporting ≥3 HbA1c tests/year at 8 and 13 years diabetes duration decreased with older age at diagnosis (odds ratio [OR] 0.91 [95% CI 0.88-0.95]), longer duration of diabetes (OR 0.90 [0.82-0.99]), not having a personal doctor (OR 0.44 [0.30-0.65]), and lapses in health insurance (OR 0.51 [0.27-0.96]). HbA1c testing ≥3 times/year over time was associated with lower HbA1c levels (OR -0.36% [-0.65 to -0.06]) and lower odds of microvascular complications (OR 0.64 [0.43-0.97]) at 13 years duration, but associations were attenuated after adjustment for HbA1c testing correlates (OR -0.17 [-0.46 to 0.13] and 0.70 [0.46-1.07], respectively). For type 2 diabetes, not seeing an endocrinologist decreased the odds of reporting ≥3 HbA1c tests/year over time (OR 0.19 [0.06-0.63]), but HbA1c testing frequency was not associated with HbA1c levels or microvascular complications.

CONCLUSIONS

We observed disparities in HbA1c testing frequency predominately by health care-related factors, which were associated with diabetes outcomes in type 1 diabetes.

Trends in Receipt of American Diabetes Association Guideline-Recommended Care Among U.S. Adults With Diabetes: NHANES 2005-2018

OBJECTIVE

To characterize national trends and characteristics of adults with diabetes receiving American Diabetes Association (ADA) guideline-recommended care.

RESEARCH DESIGN AND METHODS

We performed serial cross-sectional analyses of 4,069 adults aged ≥20 years with diabetes who participated in the 2005-2018 National Health and Nutrition Examination Survey (NHANES).

RESULTS

Overall, the proportion of U.S. adults with diabetes receiving ADA guideline-recommended care meeting all five criteria by self-report in the past year (having a primary doctor for diabetes and one or more visits for this doctor, HbA_1c testing, an eye examination, a foot examination, and cholesterol testing) increased from 25.0% in 2005-2006 to 34.1% in 2017-2018 (P-trend = 0.004). For participants with age ≥65 years, it increased from 29.3% in 2005-2006 to 44.2% in 2017-2018 (P-trend = 0.001), whereas for participants with age 40-64 and 20-39 years, it did not change significantly during the same time period: 25.2% to 25.8% (P-trend = 0.457) and 9.9% to 26.0% (P-trend = 0.401), respectively. Those who were not receiving ADA guideline-recommended care were more likely to be younger, of lower socioeconomic status, uninsured, newly diagnosed with diabetes, not on diabetes medication, and free of hypercholesterolemia.

CONCLUSIONS

Receipt of ADA guideline-recommended care increased only among adults with diabetes aged ≥65 years in the past decade. In 2017-2018, only one of three U.S. adults with diabetes reported receiving ADA guideline-recommended care, with even a lower receipt of care among those <65 years of age. Efforts are needed to improve health care delivery and equity in diabetes care. Insurance status is an important modifiable determinant of receiving ADA guideline-recommended care.

The perspectives of physicians regarding antidiabetic therapy de-intensification and factors affecting their treatment choices-A cross-sectional study

AIMS

Comprehensive diabetes management may include treatment intensification or the administration of antidiabetic combination therapy. However, this may be associated with an increased risk of adverse events and death. The aim of this study was to understand physicians' perspectives regarding treatment de-intensification, HbA1c goals individualisation, and factors affecting their treatment choice for patients with type 2 diabetes mellitus (T2DM).

METHODS

A cross-sectional study was conducted in primary and secondary care units in Saudi Arabia using online questionnaire. Two previously validated questionnaires were used to understand physicians' awareness of, agreement with, and their practices of individualising HbA1c goals and antidiabetic treatment optimisation, and to assess factors affecting physicians' treatment choice when prescribing antidiabetic treatment for patients with type 2 diabetes mellitus. Study population were physicians who are treating patients with diabetes mellitus during the period between October 2017 and May 2018.

RESULTS

A total of 205 physicians have participated in the study. Approximately 50% of physicians had family medicine speciality (n = 98, 47.8%). The majority of physicians (n = 183, 89.3%) were familiar with the concept of HbA1c goals individualisation. However, only 66.3% of them (n = 136) reported that they apply it either always or most of the time. 58.5% (n = 120) of physicians reported that they would not initiate conversations about de-intensifying antidiabetic therapy even if their patients had a stable HbA1c values for one year. Physicians showed higher consideration to objective patient clinical data and their assessment of patient's health status, with minor consideration to patient-related factors.

CONCLUSIONS

Healthcare professionals should focus more on implementing contemporary practices and applying any necessary treatment de-intensification or dose adjustment. Subjective patient factors should be taken into account further, as these factors are associated with better disease management.

Cardiovascular and renal benefits of dapagliflozin in patients with short and long-standing type 2 diabetes: Analysis from the DECLARE-TIMI 58 trial

AIM

To investigate whether the cardiovascular and renal benefits observed with dapagliflozin in the DECLARE-TIMI 58 trial are also observed in patients with short and long-standing diabetes.

MATERIALS AND METHODS

This post hoc analysis studied the dual primary efficacy endpoints, a composite of cardiovascular death or hospitalization for heart failure (CVD/HHF) and major adverse cardiovascular events (MACE; CVD, myocardial infarction [MI], ischaemic stroke) by diabetes duration.

RESULTS

Of the 17 160 patients, 3836 had diabetes duration of ≤5 years, 4731 >5-10 years, 3952 >10-15 years, 2433 >15-20 years and 2206 >20 years. Dapagliflozin reduced the risk of CVD/HHF by a similar amount across diabetes duration subgroups, ranging from HR 0.79 (0.58-1.06) in patients with diabetes duration of ≤5 years to 0.75 (0.55-1.03) in those patients with diabetes duration of >20 years (interaction trend P-value 0.76). Hazard ratios (HRs) for MACE ranged from 1.08 (0.87-1.35) in patients with diabetes duration of ≤5 years to 0.67 (0.52-0.86) in those patients with diabetes duration of >20 years (interaction trend P-value 0.004). This was driven by greater reductions in the risk of MI and ischaemic stroke with dapagliflozin in patients with long-standing diabetes (interaction trend P-values 0.019 and 0.015, respectively). The duration-based MACE heterogeneity was apparent in those with or without a history of prior MI and in those with multiple risk factors. The renal-specific outcome was reduced with dapagliflozin with HRs ranging from 0.79 (0.47-1.34) in patients with diabetes duration of ≤5 years to 0.42 (0.25-0.72) in those patients with diabetes duration of >20 years (interaction trend P-value 0.084).

CONCLUSIONS

Dapagliflozin reduced the risk of CVD/HHF consistently, regardless of diabetes duration, whereas the treatment effect for MACE differed by duration subgroups, with significant reductions with dapagliflozin in patients with long-standing diabetes.

Impact of a "Chart Closure" Hard Stop Alert on Prescribing for Elevated Blood Pressures Among Patients With Diabetes: Quasi-Experimental Study

BACKGROUND

University of California at Los Angeles Health implemented a Best Practice Advisory (BPA) alert for the initiation of an angiotensin-converting enzyme inhibitor (ACEI) or angiotensin-receptor blocker (ARB) for individuals with diabetes. The BPA alert was configured with a "chart closure" hard stop, which demanded a response before closing the chart.

OBJECTIVE

The aim of the study was to evaluate whether the implementation of the BPA was associated with changes in ACEI and ARB prescribing during primary care encounters for patients with diabetes.

METHODS

We defined ACEI and ARB prescribing opportunities as primary care encounters in which the patient had a diabetes diagnosis, elevated blood pressure in recent encounters, no active ACEI or ARB prescription, and no contraindications. We used a multivariate logistic regression model to compare the change in the probability of an ACEI or ARB prescription during opportunity encounters before and after BPA implementation in primary care sites that did (n=30) and did not (n=31) implement the BPA. In an additional subgroup analysis, we compared ACEI and ARB prescribing in BPA implementation sites that had also implemented a pharmacist-led medication management program.

RESULTS

We identified a total of 2438 opportunity encounters across 61 primary care sites. The predicted probability of an ACEI or ARB prescription increased significantly from 11.46% to 22.17% during opportunity encounters in BPA implementation sites after BPA implementation. However, in the subgroup analysis, we only observed a significant improvement in ACEI and ARB prescribing in BPA implementation sites that had also implemented the pharmacist-led program. Overall, the change in the predicted probability of an ACEI or ARB prescription from before to after BPA implementation was significantly greater in BPA implementation sites compared with nonimplementation sites (difference-in-differences of 11.82; P<.001).

CONCLUSIONS

A BPA with a "chart closure" hard stop is a promising tool for the treatment of patients with comorbid diabetes and hypertension with an ACEI or ARB, especially when implemented within the context of team-based care, wherein clinical pharmacists support the work of primary care providers.

Primary care provider adherence to an alert for intensification of diabetes blood pressure medications before and after the addition of a "chart closure" hard stop

Objective

To evaluate provider responses to a narrowly targeted "Best Practice Advisory" (BPA) alert for the intensification of blood pressure medications for persons with diabetes before and after implementation of a "chart closure" hard stop, which is non-interruptive but demands an action or dismissal before the chart can be closed.

Materials and Methods

We designed a BPA that fired alerts within an electronic health record (EHR) system during outpatient encounters for patients with diabetes when they had elevated blood pressures and were not on angiotensin receptor blocking medications. The BPA alerts were implemented in eight primary care practices within UCLA Health. We compared data on provider responses to the alerts before and after implementing a "chart closure" hard stop, and we conducted chart reviews to adjudicate each alert's appropriateness.

Results

Providers responded to alerts more often after the "chart closure" hard stop was implemented (P < .001). Among 284 alert firings over 16 months, we judged 107 (37.7%) to be clinically unnecessary or inappropriate based on chart review. Among the remainder, which represent clear opportunities for treatment, providers ordered the indicated medication more often (41% vs 75%) after the "chart closure" hard stop was implemented (P = .001).

Discussion

The BPA alerts for diabetes and blood pressure control achieved relatively high specificity. The "chart closure" hard stop improved provider attention to the alerts and was effective at getting patients treated when they needed it.

Conclusion

Targeting specific omitted medication classes can produce relatively specific alerts that may reduce alert fatigue, and using a "chart closure" hard stop may prompt providers to take action without excessively disrupting their workflow.

Lipid Testing and Statin Prescriptions Among Medicaid Recipients With Systemic Lupus Erythematosus or Diabetes Mellitus and the General Medicaid Population

OBJECTIVE

Cardiovascular disease (CVD) risks in systemic lupus erythematosus (SLE) are similar to those in diabetes mellitus (DM). We investigated whether the numbers of lipid tests and statin prescriptions in patients with SLE are comparable with those in patients with DM and those in individuals without either disease.

METHODS

Using Analytic eXtract files from 29 states for 2007-2010, we identified a cohort of US Medicaid beneficiaries, ages 18-65 years, with prevalent SLE. Each SLE patient was matched for age and sex with 2 patients with DM and 4 individuals in the general Medicaid population who did not have either SLE or DM. We compared the proportions of patients in each cohort who received ≥1 lipid test and ≥1 statin prescription during 1-year follow-up. We used multivariable logistic regression to calculate the odds of lipid testing and receiving prescriptions for statins and conditional logistic regression to compare the matched cohorts.

RESULTS

We identified 3 Medicaid cohorts: 25,950 patients with SLE, 51,900 patients with DM, and 103,800 Medicaid recipients without either condition. In these cohorts, lipid testing was performed in 24% of patients in the SLE group, 43% of patients in the DM group, and 16% of individuals in the group with neither condition, and statin prescriptions were dispensed in 11%, 33%, and 7% of these groups, respectively. SLE patients were 66% less likely (odds ratio [OR] 0.34, 95% confidence interval [95% CI] 0.34-0.35) to have lipid tests and 82% less likely (OR 0.18, 95% CI 0.18-0.18) to fill a statin prescription compared with DM patients. SLE patients were also less likely (OR 0.89, 95% CI 0.84-0.94) to fill a statin prescription compared with individuals in the general Medicaid population.

CONCLUSION

Despite having an elevated risk of CVD, SLE patients received less lipid testing and received fewer statin prescriptions compared with age- and sex-matched DM patients and individuals in the general Medicaid population; this gap should be a target for improvement.

Mortality and potential years of life lost attributable to non-optimal glycaemic control in men and women with diabetes in the United Arab Emirates: a population-based retrospective cohort study

OBJECTIVES

Numerous studies reported that achieving near-normal glycated haemoglobin (HbA1c) levels in patients with diabetes may delay or even prevent vascular complications. However, information regarding the impact of non-optimal HbA1c control on adverse health outcomes in an Arab population is unknown. The aim of this study was to estimate the fraction of deaths and potential years of life lost (PYLL) attributable to non-optimal HbA1c control among Emirati men and women with diabetes in the United Arab Emirates (UAE).

DESIGN

A retrospective cohort study.

SETTING

This study was conducted in outpatient clinics at a tertiary care centre in Al Ain, UAE, between April 2008 and September 2018.

PARTICIPANTS

The sample comprised of 583 adult UAE nationals, aged≥18 years, with diabetes. Overall, 57% (n=332) of the study participants were men and 43% (n=251) were women.

EXPOSURE

Non-optimal HbA1c control, defined as HbA1c≥6.5%.

PRIMARY OUTCOME MEASURE

All-cause mortality, defined as death from any cause.

RESULTS

At the end of the 9-year follow-up period, 86 (14.8%) participants died. Overall, up to 33% (95% CI 2% to 63%) of deaths were attributable to non-optimal HbA1c control among patients with diabetes mellitus (DM). Stratified by sex, the adjusted fraction of avoidable mortality was 17% (95% CI -23% to 57%) for men and 50% (95% CI 3% to 98%) for women. Both deaths and PYLL attributable to non-optimal HbA1c control were higher in women compared with men.

CONCLUSIONS

Up to one-third of all deaths in adult UAE nationals with DM could be attributed to non-optimal HbA1c control. Effective sex-specific interventions and healthcare quality-improvement programmes should urgently be implemented.

Mobile Health and Technology Usage by Patients in the Diabetes, Nutrition, and Weight Management Clinic at an Urban Academic Medical Center

Background: Low-income, minority, and underserved populations are often excluded from mobile health (mHealth) research. This cross-sectional study sought to define how patients at an urban, academic safety net hospital use technology in their daily lives in an effort to incorporate mHealth into clinical care and research. Methods: Patients receiving care in the Diabetes and Weight Management subspecialty clinic at Boston Medical Center were asked to complete a 17-question survey on technology usage. It was modeled on a Pew Research Center survey and available in English, Portuguese, and Spanish. Results: Of the 394 survey respondents, 279 (70.8%) completed all questions. Majority of respondents were female (76.4%) and between 30 and 49 years old (42.9%). Respondents self-identified primarily as black/African American (35.8%), white/Caucasian (28.2%), and not Hispanic/Latino (46.4%). Over 90% owned a smartphone and more than 85% accessed the Internet on a mobile device at least once per day. Regarding mHealth usage, 33.5% and 23.1% reported current use of health- and weight loss-centric applications (apps), respectively, while only 19.6% of patients with diabetes used smartphone apps as diabetes self-management tools. Nearly three-quarters (73.3%) reported interest in using apps to manage health. Respondents preferred e-mail (48.7%), phone (39.6%), and in-person communication (36.3%) as research recruitment tools. Conclusions: The overwhelming majority of an urban, underserved minority population cared for in a subspecialty clinic have access to mHealth-compatible devices and are either using or interested in using mHealth technology.

Maintenance of good glycaemic control is challenging - A cohort study of type 2 diabetes patient in North Karelia, Finland

AIMS

This study assessed type 2 diabetes treatment outcomes and process indicators using a comprehensive type 2 diabetes patient cohort in North Karelia, Finland, from 2011 to 2016.

METHODS

Data from all diagnosed type 2 diabetes patients (n = 8429) living in North Karelia were collated retrospectively from regional electronic patient records. We assessed whether HbA1c and low-density lipoprotein (LDL) were measured and managed as recommended.

RESULTS

The HbA1c measurement rate improved (78% vs 89%) during 2011-2012 and 2015-2016, but a gradual deterioration in glycaemic control (HbA1c < 7.0% or 53 mmol/mol) was observed among both females (75% vs 67%) and males (72% vs 64%). The LDL measurement rate initially improved from the baseline. LDL control (<2.5 mmol/L) improved among both females (52% vs 59%) and males (58% vs 66%). A gender difference was observed in the achievement of the treatment target for LDL, with females showing worse control.

CONCLUSIONS

Low-density lipoprotein (LDL) control in type 2 diabetes patients has improved, but the existence of gender disparities needs further attention. Maintaining appropriate HbA1c control among type 2 diabetes patients over time appears to be difficult. Active follow-up and tailored treatment have the potential to improve the quality of care. Electronic patient records could be more efficiently used to improve the quality of care and to support decision-making.

Social Risk Adjustment of Quality Measures for Diabetes and Cardiovascular Disease in a Commercially Insured US Population

IMPORTANCE

Patients' social risk factors may be associated with physician group performance on quality measures.

OBJECTIVE

To examine the association of social risk with change in physician group performance on diabetes and cardiovascular disease (CVD) quality measures in a commercially insured population.

DESIGN, SETTING, AND PARTICIPANTS

In this cross-sectional study using claims data from 2010 to 2014 from a US national health insurance plan, the performance of 1400 physician groups (physicians billing under the same tax identification number) was estimated. After base adjustments for age and sex, changes in variation across groups and reordering of rankings resulting from additional adjustments for clinical, social, or both clinical and social risk factors were analyzed. In all models, only within-group associations were adjusted to distinguish the association of patients' social risk factors with outcomes while excluding physician groups' distinct characteristics that could also change observed performance. Data analysis was conducted between April and July 2018.

MAIN OUTCOMES AND MEASURES

Process measures (hemoglobin A1c [HbA1c] testing, low-density lipoprotein cholesterol [LDL-C] testing, and statin use), disease control measures (HbA1c and LDL-C level control), and use-based outcome measures (hospitalizations for ambulatory-sensitive conditions) were calculated with base adjustment (age and sex), clinical adjustment, social risk factor adjustment, and both clinical and social adjustments. Quality variance in physician group performance and changes in rankings following these adjustments were measured.

RESULTS

This study identified 1 684 167 enrollees (859 618 [51%] men) aged 18 to 65 years (mean [SD] age, 50 [10.7] years) with diabetes or CVD. Performance rates were high for HbA1c and LDL-C level testing (mean ranged from 79.5% to 87.2%) but lower for statin use (54.7% for diabetes cohort and 44.2% for CVD cohort) and disease control measures (57.9% on LDL-C control for diabetes cohort and 40.0% for CVD cohort). On average, only 8.8% of enrollees with diabetes and 1.0% of enrollees with CVD in a group were hospitalized. The addition of clinical and social risk factors to base adjustment reduced variance across physician groups for most measures (percentage change in SD ranged from -13.9% to 1.6%). Although overall agreement between performance scores with base vs full adjustment was high, there was still substantial reordering for some measures. For example, social risk adjustment resulted in reordering for disease control in the diabetes cohort. Of the 1400 physician groups, 330 (23.6%) had performance rankings for HbA1c control that increased or decreased by at least 10 percentile points after adding social risk factors to age and sex. Both clinical and social risk adjustment affected rankings on hospital admissions.

CONCLUSIONS AND RELEVANCE

Accounting for social risk may be important to mitigate adverse consequences of performance-based payments for physician groups serving socially vulnerable populations.

Cost-effectiveness of Simple Insulin Infusion Devices Compared to Multiple Daily Injections in Uncontrolled Type 2 Diabetics in the United States Based on a Simulation Model

BACKGROUND

As type 2 diabetes (T2D) progresses, administering basal and bolus insulin through multiple daily injections (MDI) is often required to achieve target control, although many people fail to achieve target levels. Continuous subcutaneous insulin infusion (CSII) treatment with traditional pumps has proven effective in this population, but use remains limited in T2D due to CSII cost and complexity. A new class of simple insulin infusion devices have been developed which are simpler to use and less expensive. This paper assesses at what price one such simple insulin infusion device, PAQ® (Cequr SA, Switzerland), may be cost-effective compared to MDI in people with T2D not in glycemic control in the United States.

METHODS

Published equations were used in a simulation model to project long-term cost-effectiveness over 40 years, combined with data from the recent OpT2mise study, assuming similar efficacy of CSII and simple insulin infusion. Cost-effectiveness was pre-defined in relation to per capita gross domestic product (GDP), where incremental cost-effectiveness ratios below 1X the per capita GDP per quality-adjusted life year (QALY) gained were defined as "highly cost-effective" and below 3X GDP per capita as "cost-effective."

RESULTS

Simple insulin infusion resulted in 0.17 QALYs gained per patient compared to MDI, along with lifetime cost-savings of USD 66 883 per person due to reduced insulin use and less complications. Analyses on price sensitivity of simple insulin infusion indicated that a device such as the PAQ is cost-effective compared with MDI up to price points of around USD 17 per day.

CONCLUSIONS

For people with T2D not in glycemic control on MDI, simple insulin infusion devices such as PAQ have the potential to be highly cost-effective in the United States.

Pharmacist Impact on Treatment Intensification and Hemoglobin A1C in Patients With Type 2 Diabetes Mellitus at an Academic Health Center

Background:

Achievement of treatment goals for patients with type 2 diabetes mellitus (T2DM) is suboptimal. This is in part driven by a lack of treatment intensification when warranted, termed “clinical inertia.”

Objectives:

To investigate time to treatment intensification and changes in A1C among pharmacist–physician managed (PPM) patients compared to usual medical care (UMC) in patients with T2DM.

Methods:

Retrospective matched cohort study at 2 academic family medicine clinics. Patients in each cohort were matched 1:1 based on age (±5 years), primary care provider, gender, and race.

Results:

A total of 50 patients met inclusion criteria. Mean time to treatment intensification was longer in the UMC cohort as compared with the PPM cohort (325 (66) days vs 200 (62) days [ P = .50]). A higher percentage of patients in the PPM cohort achieved ≥0.5% reduction in A1C in comparison to the UMC cohort (60% vs 44%, respectively [ P = .41]). Patients in the PPM cohort experienced a greater mean decrease in A1C from baseline when compared to patients in the UMC cohort (−1% (1.8%) vs −0.4% (2.2%) [ P = .24]).

Conclusion:

Patients exposed to a pharmacist in this retrospective matched cohort study experienced shorter time to treatment intensification and a greater reduction in A1C than those managed solely by a medical provider, although results were not statistically significant. Additional research is needed to evaluate the role of the pharmacist in improving clinical inertia in the management of T2DM.

Rethinking the Viability and Utility of Inhaled Insulin in Clinical Practice

Despite considerable advances in pharmacotherapy and self-monitoring technologies in the last decades, a large percentage of adults with diabetes remain unsuccessful in achieving optimal glucose due to suboptimal medication adherence. Contributors to suboptimal adherence to insulin treatment include pain, inconvenience, and regimen complexity; however, a key driver is hypoglycemia. Improvements in the PK/PD characteristics of today's SC insulins provide more physiologic coverage of basal and prandial insulin requirements than regular human insulin; however, they do not achieve the rapid on/rapid off characteristics of endogenously secreted insulin seen in healthy, nondiabetic individuals. Pulmonary administration of prandial insulin represents an attractive option that overcomes limitations of SC insulin by providing more a rapid onset of action and a faster return of action to baseline levels than SC administration of rapid-acting insulin analogs. This article reviews the unique PK/PD properties of a novel inhaled formulation that support its use in patient populations with T1D or T2D.

Improving diabetes care at primary care level with a multistrategic approach: results of the DIAPREM programme

AIM

To present results, 1 year postimplementation at primary care level, of an integrated diabetes care programme including systemic changes, education, registry (clinical, metabolic, and therapeutic indicators), and disease management (DIAPREM).

METHODS

We randomly selected and trained 15 physicians and 15 nurses from primary care units of La Matanza County (intervention-IG) and another 15 physicians/nurses to participate as controls (control-CG). Each physician-nurse team controlled and followed up 10 patients with type 2 diabetes for 1 year; both groups used structured medical records. Patients in IG had quarterly clinical appointments, whereas those in CG received traditional care. Statistical data analysis included parametric/nonparametric tests according to data distribution profile and Chi-squared test for proportions.

RESULTS

After 12 months, the dropout rate was significantly lower in IG than in CG. Whereas in IG HbA1c, blood pressure and lipid profile levels significantly decreased, no changes were recorded in CG. Drug prescriptions showed no significant changes in IG except a decrease in oral monotherapy.

CONCLUSIONS

DIAPREM is an expedient and simple multistrategic model to implement at the primary care level in order to decrease patient dropout and improve control and treatment adherence, and quality of care of people with diabetes.

The Impact of Structured Self-Monitoring of Blood Glucose Combined With Intensive Education on HbA1c Levels, Hospitalizations, and Quality-of-Life Parameters in Insulin-Treated Patients With Diabetes at Primary Care in Serbia: The Multicenter SPA-EDU Study

BACKGROUND

We assessed the effect of structured self-monitoring of blood glucose (SMBG), in combination with intensive education, on metabolic control, SMBG frequency, hospitalizations, cardiovascular risk factors, and quality-of-life parameters in patients with insulin-treated diabetes in primary health care settings in Serbia.

METHODS

This 6-month, observational, noninterventional study, followed 346 insulin-treated diabetes patients (type 1 diabetes [T1D], n = 57; type 2 diabetes [T2D], n = 289) from 28 primary care centers. Patients attended a 10-day course at the specialized educational center and were followed monthly by their primary care physicians. Patients used a simple paper tool to document 3-day, 7-point glucose profiles prior to each monthly clinic visit. Physicians reviewed the completed forms at each visit and used a standardized education program to provide remedial training. Changes in HbA1c levels, SMBG frequency, metabolic risk factors, and Diabetes Distress Scale (DDS) were assessed.

RESULTS

Mean (± SD) HbA1c within the full cohort was significantly improved from baseline at 6 months (8.85 ± 1.17% vs 7.91 ± 1.24%, P < .01). Significant increases in average SMBG frequency per week were seen at 6 months versus baseline (14.6/week vs 4.3/week, P < .001). The mean (± SE) number of hospitalizations due to metabolic conditions was significantly lower during the 6-month study compared to the 6-month period prior to the study (0.14 ± 0.04 vs 0.59 ± 0.09). DDS scores decreased from 39.6 ± 13.9 to 33.9 ± 14.5, P < .01.

CONCLUSION

The use of structured SMBG combined with intensive education was associated with clinically significant reductions in HbA1c, increased SMBG frequency, and improved quality of life.

Assessing Psychological Insulin Resistance in Type 2 Diabetes: a Critical Comparison of Measures

PURPOSE OF REVIEW

This study aims to examine the operationalisation of 'psychological insulin resistance' (PIR) among people with type 2 diabetes and to identify and critique relevant measures.

RECENT FINDINGS

PIR has been operationalised as (1) the assessment of attitudes or beliefs about insulin therapy and (2) hypothetical or actual resistance, or unwillingness, to use to insulin. Five validated PIR questionnaires were identified. None was fully comprehensive of all aspects of PIR, and the rigour and reporting of questionnaire development and psychometric validation varied considerably between measures. Assessment of PIR should focus on the identification of negative and positive attitudes towards insulin use. Actual or hypothetical insulin refusal may be better conceptualised as a potential consequence of PIR, as its assessment overlooks the attitudes that may prevent insulin use. This paper provides guidance on the selection of questionnaires for clinical or research purpose and the development of new, or improvement of existing, questionnaires.

Yusof MA, Ahmad Lutfi N, Thye SL, Ismail F, Mahmud M, Bakri R. Evaluation of awareness & utilisation of clinical practise guideline for management of adult Dengue infection among Malaysia doctors

Clinical Practice Guideline (CPG) provides evidence-based guidance for the management of Dengue Infection in adult patients. A cross sectional study was conducted to evaluate awareness and utilization of CPG among doctors in public or private hospitals and clinics in Malaysia. Doctors practicing only at hospital Medical and Emergency Departments were included, while private specialist clinics were excluded in this study. A multistage proportionate random sampling according to region (Central, Northern, Southern, Eastern, Sabah and Sarawak) was performed to select study participants. The overall response rate was 74% (84% for public hospitals, 82% for private hospitals, 70% for public clinics, and 64% for private clinics). The CPG Awareness and Utilization Feedback Form were used to determine the percentage in the study. The total numbers of respondent were 634 with response rate of 74%. The mean lengths of service of the respondent were 13.98 (11.55).A higher percentages of doctors from public facilities (99%) were aware of the CPG compared to those in private facilities (84%). The percentage of doctors utilising the CPG were also higher (98%) in public facilities compared to private facilities (86%). The percentage of Medical Officer in private facilities that utilizing the CPG were 84% compares to Medical Officer in public facilities 98%. The high percentage of doctors using the CPG in both public (97%) and private (94%) hospitals were also observed. However, only 69% of doctors in private clinics utilised the CPG compared to doctors in public clinics (98%). Doctors in both public and private facilities were aware of the dengue CPG. However, most doctors in private clinic were less likely to utilise the CPG. Therefore, there is a need to increase the level of CPG utilisation especially in private clinics.

Multistrategic approach to improve quality of care of people with diabetes at the primary care level: Study design and baseline data

AIM

To test the one year-post effect of an integrated diabetes care program that includes system changes, education, registry (clinical, metabolic and therapeutic indicators) and disease management (DIAPREM), implemented at primary care level, on care outcomes and costs.

METHODS

We randomly selected 15 physicians and 15 nurses from primary care units of La Matanza County to be trained (Intervention-IG) and another 15 physicians/nurses to use as controls (Control-CG). Each physician-nurse team controlled and followed up 10 patients with type 2 diabetes for one year; both groups use structured medical data registry. Patients in IG had quarterly clinical appointments whereas those in CG received traditional care. DIAPREM includes system changes (use of guidelines, programmed quarterly controls and yearly visits to the specialist) and education (physicians' and nurses' training courses). Statistical data analysis included parametric/nonparametric tests according to data distribution profile and Chi-squared test for proportions.

RESULTS

Baseline data from both groups showed comparable values and 20-30% of them did not perform HbA1c and lipid profile measurements. Majority were obese, 59% had HbA1C ≥7%, 86% fasting blood glucose ≥100mg/dL, 45%, total cholesterol ≥200mg/dL, and 92% abnormal HDL- and LDL-cholesterol values. Similarly, micro and macroangiopathic complications had not been detected in the previous year. Most patients received oral antidiabetic agents (monotherapy), and one third was on insulin (mostly a single dose of an intermediate/long-acting formulation). Most people with hypertension received specific drug treatment but only half of them reached target values; dyslipidemia treatment showed similar data.

CONCLUSIONS

Baseline data demonstrated the need of implementing an intervention to improve diabetes care and treatment outcomes.

Decreased rates of hypoglycemia following implementation of a comprehensive computerized insulin order set and titration algorithm in the inpatient setting

OBJECTIVES

More than one-third of hospitalized patients have hyperglycemia. Despite evidence that improving glycemic control leads to better outcomes, achieving recognized targets remains a challenge. The objective of this study was to evaluate the implementation of a computerized insulin order set and titration algorithm on rates of hypoglycemia and overall inpatient glycemic control.

METHODS

A prospective observational study evaluating the impact of a glycemic order set and titration algorithm in an academic medical center in non-critical care medical and surgical inpatients. The initial intervention was hospital-wide implementation of a comprehensive insulin order set. The secondary intervention was initiation of an insulin titration algorithm in two pilot medicine inpatient units. Point of care testing blood glucose reports were analyzed. These reports included rates of hypoglycemia (BG < 70 mg/dL) and hyperglycemia (BG >200 mg/dL in phase 1, BG > 180 mg/dL in phase 2).

RESULTS

In the first phase of the study, implementation of the insulin order set was associated with decreased rates of hypoglycemia (1.92% vs 1.61%; p < 0.001) and increased rates of hyperglycemia (24.02% vs 27.27%; p < 0.001) from 2010 to 2011. In the second phase, addition of a titration algorithm was associated with decreased rates of hypoglycemia (2.57% vs 1.82%; p = 0.039) and increased rates of hyperglycemia (31.76% vs 41.33%; p < 0.001) from 2012 to 2013.

CONCLUSIONS

A comprehensive computerized insulin order set and titration algorithm significantly decreased rates of hypoglycemia. This significant reduction in hypoglycemia was associated with increased rates of hyperglycemia. Hardwiring the algorithm into the electronic medical record may foster adoption.

The impact of insulin therapy and attitudes towards insulin intensification among adults with type 2 diabetes: A qualitative study

BACKGROUND

As type 2 diabetes (T2DM) is a progressive chronic condition, regular clinical review and treatment intensification are critical for prevention of long-term complications. Our aim was to explore the personal impact of insulin therapy, both positive and negative consequences, and attitudes towards future insulin intensification.

METHODS

Twenty face-to-face interviews were conducted, and transcripts were analysed using thematic inductive analysis. Eligible participants were adults with T2DM, using insulin injections for <4years. Participants were mostly men (n=13, 65%), (median (range)) aged 65 (43-76) years, living with T2DM for 11.5 (2-27) years.

RESULTS

Five themes emerged regarding the consequences (positive and negative) of insulin therapy, including: physical impact, personal control, emotional well-being, freedom/flexibility, (concerns about) others' reactions. Increased inconvenience and the perceived seriousness of using fast-acting insulin were both reported as barriers to future insulin intensification, despite most participants being receptive to the idea of administering additional injections.

CONCLUSIONS

Positive and negative experiences of insulin therapy were reported by adults with T2DM and most were receptive to insulin intensification despite reported barriers. These findings may inform clinical interactions with people with T2DM and interventions to promote receptiveness to insulin initiation and intensification.

Frequent use of an automated bolus advisor improves glycemic control in pediatric patients treated with insulin pump therapy: results of the Bolus Advisor Benefit Evaluation (BABE) study

BACKGROUND

The relationship between frequency and sustained bolus advisor (BA) use and glycemic improvement has not been well characterized in pediatric populations.

OBJECTIVE

The objective of this study is to assess the impact of frequent and persistent BA use on glycemic control among pediatric type 1 diabetes patients.

METHODS

In this 6-month, single-center, retrospective cohort study, 104 children [61 girls, mean age: 12.7 yr, mean HbA1c 8.0 (1.6)% [64 (17.5) mmol/mol]], treated with the Accu-Chek Aviva Combo insulin pump, were observed. Frequency of BA use, HbA1c, hypoglycemia (<70 mg/dL), therapy changes, mean blood glucose, and glycemic variability (standard deviation) was assessed at baseline and month 6. Sub-analyses of the adolescent patient use (12 months) and longitudinal use (24 months) were also conducted.

RESULTS

Seventy-one patients reported high frequency (HF) device use (≥50%); 33 reported low frequency (LF) use (<50%) during the study. HF users achieved lower mean (SE) HbA1c levels than LF users: 7.5 (0.1)% [59 (1.1) mmol/mol] vs. 8.0 (0.2)% [64 (2.2) mmol/mol], p = 0.0252. No between-group differences in the percentage of hypoglycemia values were seen at 6 months. HF users showed less glycemic variability (84.0 vs. 94.7, p = 0.0045) than LF users. More HF patients reached HbA1c target of <7.5 at 6 months 66.2% (+16.9) vs. 27.3% (-9.1), p = 0.0056. Similar HbA1c results were seen in adolescents and BA users at 24 months.

CONCLUSION

Frequent use of the Accu-Chek Aviva Combo insulin pump BA feature was associated with improved and sustained glycemic control with no increase in hypoglycemia in this pediatric population.

Measuring and improving quality in university hospitals in Canada: The Collaborative for Excellence in Healthcare Quality

Measuring and monitoring overall health system performance is complex and challenging but is crucial to improving quality of care. Today's health care organizations are increasingly being held accountable to develop and implement actions aimed at improving the quality of care, reducing costs, and achieving better patient-centered care. This paper describes the development of the Collaborative for Excellence in Healthcare Quality (CEHQ), a 5-year initiative to achieve higher quality of patient care in university hospitals across Canada. This bottom-up initiative took place between 2010 and 2015, and was successful in engaging health care leaders in the development of a common framework and set of performance measures for reporting and benchmarking, as well as working on initiatives to improve performance. Despite its successes, future efforts are needed to provide clear national leadership on standards for measuring performance.

Evaluation of a patient self-directed mealtime insulin titration algorithm: a US payer perspective

Objective To model the potential economic impact of implementing the AUTONOMY once daily (Q1D) patient self-titration mealtime insulin dosing algorithm vs standard of care (SOC) among a population of patients with Type 2 diabetes living in the US. Methods Three validated models were used in this analysis: The Treatment Transitions Model (TTM) was used to generate the primary results, while both the Archimedes (AM) and IMS Core Diabetes Models (IMS) were used to test the veracity of the primary results produced by TTM. Models used data from a 'real world' representative sample of patients (2012 US National Health and Nutrition Examination Survey) that matched the characteristics of US patients enrolled in the randomized controlled trial 'AUTONOMY' cohort. The base-case time horizon was 10 years. Results The modeling results from TTM demonstrated that total costs in the base-case were reduced by $1732, with savings predicted to occur as early as year 1. Results from the three models were consistent, showing a reduction in total costs for all sensitivity analyses. Limitations Data from short-term clinical trials were used to develop long-term projections. The nature of such extrapolation leads to increased uncertainty. Conclusion The results from all three models indicate that the AUTONOMY Q1D algorithm has the potential to abate total costs as early as the first year.

An expanded model of diabetes care based in an analysis and critique of current approaches

AIMS AND OBJECTIVES

To examine and critique various models guiding the care and education of people with diabetes, to develop more helpful and effective approaches to care. The focus is on relationships and communication between patients and healthcare providers.

BACKGROUND

Many patients are not adhering to the recommended treatments, hence it seems that effective diabetes care is difficult to achieve, particularly for patients of lower socio-economic status, who are disproportionately afflicted. The results are usually devastating, and lead to serious health complications that incisively diminish quality of life for patients with diabetes, frustrate healthcare providers and increase healthcare costs.

DESIGN

Critical review.

METHOD

This paper represents a critical review of various approaches to diabetes care and education. A CINAHL search with relevant key words was carried out and selected exemplary research studies and articles describing and/or evaluating the various approaches to diabetes care and management were examined. Particular attention was paid to how the paradigmatic underpinnings of these approaches construct patient - healthcare provider relationships.

CONCLUSION

The literature revealed that the traditional top-down approaches to care were largely ineffective, while collaborative approaches, based in respect and taking the whole persons and their unique situations into account, were found to be central to good care. Further, an integration of the different kinds of knowledge contained in the various approaches can complement and extend one another.

RELEVANCE TO CLINICAL PRACTICE

Avoiding devastating complications by improving the management of diabetes and overall quality of life of patients is a worthwhile goal. Therefore expanding diabetes care beyond the traditional bio-medical model to develop more effective approaches to care is of interest to all healthcare professionals working in this area.

Medication Adherence Does Not Explain Black-White Differences in Cardiometabolic Risk Factor Control among Insured Patients with Diabetes

BACKGROUND

Among patients with diabetes, racial differences in cardiometabolic risk factor control are common. The extent to which differences in medication adherence contribute to such disparities is not known. We examined whether medication adherence, controlling for treatment intensification, could explain differences in risk factor control between black and white patients with diabetes.

METHODS

We identified three cohorts of black and white patients treated with oral medications and who had poor risk factor control at baseline (2009): those with glycated hemoglobin (HbA1c) >8 % (n = 37,873), low-density lipoprotein cholesterol (LDL-C) >100 mg/dl (n = 27,954), and systolic blood pressure (SBP) >130 mm Hg (n = 63,641). Subjects included insured adults with diabetes who were receiving care in one of nine U.S. integrated health systems comprising the SUrveillance, PREvention, and ManagEment of Diabetes Mellitus (SUPREME-DM) consortium. Baseline and follow-up risk factor control, sociodemographic, and clinical characteristics were obtained from electronic health records. Pharmacy-dispensing data were used to estimate medication adherence (i.e., medication refill adherence [MRA]) and treatment intensification (i.e., dose increase or addition of new medication class) between baseline and follow-up. County-level income and educational attainment were estimated via geocoding. Logistic regression models were used to test the association between race and follow-up risk factor control. Models were specified with and without medication adherence to evaluate its role as a mediator.

RESULTS

We observed poorer medication adherence among black patients than white patients (p < 0.01): 50.6 % of blacks versus 39.7 % of whites were not highly adherent (i.e., MRA <80 %) to HbA1c oral medication(s); 58.4 % of blacks and 46.7 % of whites were not highly adherent to lipid medication(s); and 33.4 % of blacks and 23.7 % of whites were not highly adherent to BP medication(s). Across all cardiometabolic risk factors, blacks were significantly less likely to achieve control (p < 0.01): 41.5 % of blacks and 45.8 % of whites achieved HbA1c <8 %; 52.6 % of blacks and 60.8 % of whites achieved LDL-C <100; and 45.7 % of blacks and 53.6 % of whites achieved SBP <130. Adjusting for medication adherence/treatment intensification did not alter these patterns or model fit statistics.

CONCLUSIONS

Medication adherence failed to explain observed racial differences in the achievement of HbA1c, LDL-C, and SBP control among insured patients with diabetes.

Therapeutic inertia and intensified treatment in diabetes mellitus prescription patterns: A nationwide population-based study in Taiwan

Objective

To measure therapeutic inertia by characterizing prescription patterns using secondary data obtained from the nationwide diabetes mellitus pay-for-performance (DM-P4P) programme in Taiwan.

Methods

Using reimbursement claims from Taiwan’s National Health Insurance Research Database, a nationwide retrospective cohort study was undertaken of patients with diabetes mellitus who participated in the DM-P4P programme from 2006–2008. Glycosylated haemoglobin results were used to evaluate modifications in therapy in response to poor diabetes control. Prescription patterns were used to assign patients to either a therapeutic inertia group or an intensified treatment group. Therapeutic inertia was defined as the failure to act on a known problem.

Results

The research sample comprised of 168 876 patients with diabetes mellitus who had undergone 899 135 tests. Of these, 37.4% (336 615 visits) of prescriptions were for a combination of two types of drug and 27.7% (248 788 visits) were for a combination of three types of drug. The proportion of patients in the intensified therapy group who were prescribed more than two types of drug was considerably higher than that in the therapeutic inertia group.

Conclusion

In many cases in the therapeutic inertia group only a single type of hypoglycaemic drug was prescribed or the dosage remained unchanged.

Challenges associated with insulin therapy progression among patients with type 2 diabetes: Latin American MOSAIc study baseline data

BACKGROUND

Poor glycemic control in patients with type 2 diabetes is commonly recorded worldwide; Latin America (LA) is not an exception. Barriers to intensifying insulin therapy and which barriers are most likely to negatively impact outcomes are not completely known. The objective was to identify barriers to insulin progression in individuals with type 2 diabetes mellitus (T2DM) in LA countries (Mexico, Brazil, and Argentina).

METHODS

MOSAIc is a multinational, non-interventional, prospective, observational study aiming to identify the patient-, physician-, and healthcare-based factors affecting insulin intensification. Eligible patients were ≥18 years, had T2DM, and were treated with insulin for ≥3 months with/without oral antidiabetic drugs (OADs). Demographic, clinical, and psychosocial data were collected at baseline and regular intervals during the 24-month follow-up period. This paper however, focuses on baseline data analysis. The association between glycated hemoglobin (HbA1c) and selected covariates was assessed.

RESULTS

A trend toward a higher level of HbA1c was observed in the LA versus non-LA population (8.40 ± 2.79 versus 8.18 ± 2.28; p ≤ 0.069). Significant differences were observed in clinical parameters, treatment patterns, and patient-reported outcomes in LA compared with the rest of the cohorts and between Mexico, Brazil, and Argentina. Higher number of insulin injections and lower number of OADs were used, whereas a lower level of knowledge and a higher level of diabetes-related distress were reported in LA. Covariates associated with HbA1c levels included age (-0.0129; p < 0.0001), number of OADs (0.0835; p = 0.0264), higher education level (-0.2261; p = 0.0101), healthy diet (-0.0555; p = 0.0083), self-monitoring blood glucose (-0.0512; p = 0.0033), hurried communication style in the process of care (0.1295; p = 0.0208), number of insulin injections (0.1616; p = 0.0088), adherence (-0.1939; p ≤ 0.0104), and not filling insulin prescription due to associated cost (0.2651; p = 0.0198).

CONCLUSION

MOSAIc baseline data showed that insulin intensification in LA is not optimal and identified several conditions that significantly affect attaining appropriate HbA1c values. Tailored public health strategies, including education, should be developed to overcome such barriers. Trial Registration NCT01400971.

Geographic patterns in patient demographics and insulin use in 18 countries, a global perspective from the multinational observational study assessing insulin use: understanding the challenges associated with progression of therapy (MOSAIc)

BACKGROUND

Among patients with type 2 diabetes, insulin intensification to achieve glycemic targets occurs less often than clinically indicated. Barriers to intensification are not well understood. We present patients' baseline characteristics from MOSAIc, a study investigating patient-, physician-, and healthcare environment-based factors affecting insulin intensification and subsequent health outcomes.

METHODS

MOSAIc is a longitudinal, observational study following patients' diabetes care in 18 countries: United Arab Emirates (UAE), Argentina, Brazil, Canada, China, Germany, India, Israel, Italy, Japan, Mexico, Russia, Saudi Arabia, South Korea, Spain, Turkey, United Kingdom, United States. Eligible patients are age ≥ 18, have type 2 diabetes, and have used insulin for ≥ 3 months with/without other antidiabetic medications. Extensive baseline demographic, clinical, and psychosocial data are collected at baseline and regular intervals during the 24-month follow-up. We conducted descriptive analyses of baseline data.

RESULTS

Four thousand three hundred forty one patients met eligibility criteria. Patients received their type 2 diabetes diagnosis 12 ± 8 years prior to baseline visit, yet patients in developing countries were younger than in developed countries (e.g., UAE, 55 ± 10; Germany = 70 ± 10). Saudi Arabians had the highest HbA1c values (9.0 ± 2.2) and Germany (7.5 ± 1.4) among the lowest. Most patients in 5 (28%) of the 18 countries did not use an oral antidiabetic drug. Over half of patients in fourteen (78 %) countries exclusively used basal insulin; most Indian and Chinese patients exclusively used mixed insulin.

CONCLUSIONS

MOSAIc's baseline data highlight differences in patient characteristics across countries. These patterns, along with physician and healthcare environment differences, may contribute to the likelihood of insulin intensification and subsequent clinical outcomes.

Effects of three injectable antidiabetic agents on glycaemic control, weight change and drop-out in type 2 diabetes suboptimally controlled with metformin and/or a sulfonylurea: A network meta-analysis

AIMS

The objective of this review was to assess glucagon-like peptide-1 receptor agonists (GLP-1 RAs), basal insulin, and premixed insulin among participants with type 2 diabetes inadequately controlled with metformin and/or a sulfonylurea.

METHODS

We searched PubMed, EmBase, and the Cochrane Library to identify eligible randomized controlled trials (RCTs) for a network meta-analysis.

RESULTS

A total of 17 RCTs involving 5874 adult individuals were included. Compared with placebo, all three therapies showed a significant effect on achieving target glycated hemoglobin (HbA1c) (GLP-1 RAs: 31.7%, 95% CI, 24.7-38.6%; premixed insulin: 31.1%, 95% CI, 20.4-41.8%; basal insulin: 26.0%, 95% CI, 16.4-35.7%). However, there was no significant difference between the three therapies. A similar result was found in HbA1c reduction. The use of GLP-1 RAs resulted in significant body weight loss (-3.73 kg, 95% CI, -4.52 to -2.95 kg vs. basal insulin and -5.27 kg, 95% CI, -6.17 to -4.36 kg vs. premixed insulin) but there was a higher drop-out rate of participants. Premixed insulin seemed associated with more severe hypoglycemic episodes.

CONCLUSIONS

The three injectables had similar impact on glycemic control but other differentiating features relevant to the management of type 2 diabetes with GLP-1 RAs having the most favorable profile.

Cardiovascular risk profiles of adults with type-2 diabetes treated at urban hospitals in Riyadh, Saudi Arabia

Diabetes mellitus substantially increases cardiovascular disease (CVD) risk. Among Saudi Arabian citizens with diabetes, little is known about the prevalence and control of other CVD risk factors.

We extracted data from medical records of a random selection of 422 patients seen between 2008 and 2012 at two diabetic clinics in Riyadh, Saudi Arabia. We calculated the proportion of patients who had additional CVD risk factors: obesity (body mass index ⩾ 30 kg/m²), hypertension (BP ⩾ 140/90 mmHg), elevated cholesterol fractions, and multiple risk factors). Further, we calculated the proportion of patients meeting the American Diabetes Association’s recommended care targets for each risk factor.

Of 422 patients (mean age, 52 years), half were women, 56% were obese, 45% had hypertension, and 77% had elevated LDL concentrations. In addition to diabetes, 70% had two or more CVD risk factors. Although 9% met both target HbA1c and BP values, only 3.5% had optimum HbA1c, BP, and lipid values.

In Saudi Arabia’s best diabetes clinics, most patients have poor control of their disease. This huge disease burden and related care gaps have important health and financial implications for the country.

How Durable Are the Effects After Metabolic Surgery?

Bariatric surgery was initially developed as a tool for weight reduction only, but it is gaining popularity because of its remarkable effect on glucose metabolism in morbidly obese and less obese patients. Recent publications have shown the superiority of metabolic surgery over medical treatment for diabetes, creating a new field of clinical research that is currently overflowing in the medical community with outstanding high-quality data. Metabolic surgery is effective in treating diabetes, even in non-morbidly obese patients.

Randomized trial of a health IT tool to support between-visit-based laboratory monitoring for chronic disease medication prescriptions

BACKGROUND

Lack of timely medication intensification and inadequate medication safety monitoring are two prevalent and potentially modifiable barriers to effective and safe chronic care. Innovative applications of health information technology tools may help support chronic disease management.

OBJECTIVE

To examine the clinical impact of a novel health IT tool designed to facilitate between-visit ordering and tracking of future laboratory testing.

DESIGN AND PARTICIPANTS

Clinical trial randomized at the provider level (n = 44 primary care physicians); patient-level outcomes among 3,655 primary care patients prescribed 5,454 oral medicines for hyperlipidemia, diabetes, and/or hypertension management over a 12-month period.

MAIN MEASURES

Time from prescription to corresponding follow-up laboratory testing; proportion of follow-up time that patients achieved corresponding risk factor control (A1c, LDL); adverse event laboratory monitoring 4 weeks after medicine prescription.

KEY RESULTS

Patients whose physicians were allocated to the intervention (n = 1,143) had earlier LDL laboratory assessment compared to similar patients (n = 703) of control physicians [adjusted hazard ratio (aHR): 1.15 (1.01-1.32), p = 0.04]. Among patients with elevated LDL (486 intervention, 324 control), there was decreased time to LDL goal in the intervention group [aHR 1.26 (0.99-1.62)]. However, overall there were no significant differences between study arms in time spent at LDL or HbA1c goal. Follow-up safety monitoring (e.g., creatinine, potassium, or transaminases) was relatively infrequent (ranging from 7 % to 29 % at 4 weeks) and not statistically different between arms. Intervention physicians indicated that lack of reimbursement for non-visit-based care was a barrier to use of the tool.

CONCLUSIONS

A health IT tool to support between-visit laboratory monitoring improved the LDL testing interval but not LDL or HbA1c control, and it did not alter safety monitoring. Adoption of innovative tools to support physicians in non-visit-based chronic disease management may be limited by current visit-based financial and productivity incentives.

Use of an Electronic Medical Record (EMR) to Identify Glycemic Intensification Strategies in Type 2 Diabetes

BACKGROUND

Current treatment guidelines for type 2 diabetes (T2D) recommend individualized intensification of therapy for glycated hemoglobin (A1C) ≥ 7% in most patients. The purpose of this investigation was to explore the ability of an electronic medical record (EMR) to identify glycemic intensification strategies among T2D patients receiving pharmacologic therapy.

METHODS

Patient records between 2005 and 2011 with documentation of A1C and active prescriptions for any diabetes medications were queried to identify potential candidates for intensification based on A1C ≥ 7% while on 1-2 oral diabetes medications (ODM). Patients with follow-up A1C values within 1 year of index A1C were grouped according to intensification with insulin, GLP-1 receptor agonists (GLP-1RA), a new class of ODM, or no intensification. Changes in A1C and continuation of intensification therapy were determined.

RESULTS

A total of 4921 patients meeting inclusion criteria were intensified with insulin (n = 416), GLP-1RA (n = 68), ODM (n = 1408), or no additional therapy (n = 3029). Patients receiving insulin had higher baseline (9.3 ± 2.0 vs 8.3 ± 1.2 vs 8.3 ± 1.3 vs 7.6 ± 1.0%, P < .0001) and follow-up A1C (8.1 ± 1.6 vs 7.5 ± 1.2 vs 7.6 ± 1.3 vs 7.2 ± 1.1%, P < .0001) despite experiencing larger absolute A1C reductions (-1.2 ± 2.1 vs -0.8 ± 1.4 vs -0.7 ± 1.4 vs -0.3 ± 1.1%, P < .0001). Patients receiving GLP-1RA were more obese at baseline (BMI: 33.6 ± 7.1 vs 37.7 ± 6.1 vs 33.7 ± 6.8 vs 32.9 ± 7.1 kg/m(2), P < .0001) and follow-up (BMI: 33.9 ± 7.3 vs 36.6 ± 6.1 vs 33.8 ± 7.0 vs 32.4 ± 7.0 kg/m(2), P < .0001) despite experiencing more absolute weight reduction. Insulin was the most and GLP-1RA the least likely therapy to be continued.

CONCLUSIONS

An EMR allows identification of prescribing practices and compliance with T2D treatment guidelines. Patients receiving intensification of glycemic medications had baseline A1C >8% suggesting that treatment recommendations are not being followed.

Comparison of the adherence to the american diabetes association guidelines of diabetes care in primary care and subspecialty clinics

Background

Diabetes mellitus is a major public health problem with significant morbidity and mortality. Evidence based guidelines have been proposed to reduce the micro and macrovascular complications, but studies have shown that these goals are not being met. We sought to compare the adherence to the American Diabetes Association guidelines for measurement and control of glycohemoglobin (A1c), blood pressure (BP), lipids (LDL) and microalbuminuria (MA) by subspecialty and primary care clinics in an academic medical center.

Methods

390 random charts of patients with diabetes from Family Practice (FP), Internal Medicine (IM) and Diabetes (DM) clinics at Michigan State University were reviewed.

Results

We reviewed 131, 134 and 125 charts from the FP, IM and DM clinics, respectively. DM clinic had a higher percentage of patients with type 1 diabetes 43/125 (34.4%) compared with 7/131 (5.3%) in FP and 7/134 (5.2%) in IM clinics. A1c was measured in 99%, 97.8% and 100% subjects in FP, IM and DM clinics respectively. B.P. was measured in all subjects in all three clinics. Lipids were checked in 97.7%, 95.5% and 92% patients in FP, IM and DM clinics respectively. MA was measured at least once during the year preceding the office visit in 85.5%, 82.8% and 76.8% patients in FP, IM and DM clinics respectively. A1C was controlled (<7%) in 38.9, 43.3, 28.8% of patients in the FP, IM and DM clinics, respectively (p = 0.034). LDL was controlled (<100 mg/dl or 2.586 mmol/l) in 71.8, 64.9, 64% of patients in the FP, IM and DM clinics, respectively. MA was controlled (<30 mg/gm creatinine) in 60.3%, 51.5% and 60% patients in FP, IM and DM clinics respectively (P = 0.032). BP was controlled (<130/80) in 59.5, 67.2 and 52.8% patients in the FP, IM and DM clinics, respectively.

Conclusion

Testing rates for A1C, LDL, and MA were high, in both subspecialty and primary care clinics. However, the degree of control was not optimal. Significantly fewer patients in the DM clinic had A1c <7%, the cause of which may be multifactorial.

An online spaced-education game among clinicians improves their patients' time to blood pressure control: a randomized controlled trial

BACKGROUND

Many patients with high blood pressure (BP) do not have antihypertensive medications appropriately intensified at clinician visits. We investigated whether an online spaced-education (SE) game among primary care clinicians can decrease time to BP target among their hypertensive patients.

METHODS AND RESULTS

A 2-arm randomized trial was conducted over 52 weeks among primary care clinicians at 8 hospitals. Educational content consisted of 32 validated multiple-choice questions with explanations on hypertension management. Providers were randomized into 2 groups: SE clinicians were enrolled in the game, whereas control clinicians received identical educational content in an online posting. SE game clinicians were e-mailed 1 question every 3 days. Adaptive game mechanics resent questions in 12 or 24 days if answered incorrectly or correctly, respectively. Clinicians retired questions by answering each correctly twice consecutively. Posting of relative performance among peers fostered competition. Primary outcome measure was time to BP target (<140/90 mm Hg). One hundred eleven clinicians enrolled. The SE game was completed by 87% of clinicians (48/55), whereas 84% of control clinicians (47/56) read the online posting. In multivariable analysis of 17 866 hypertensive periods among 14 336 patients, the hazard ratio for time to BP target in the SE game cohort was 1.043 (95% confidence interval, 1.007-1.081; P=0.018). The number of hypertensive episodes needed to treat to normalize one additional patient's BP was 67.8. The number of clinicians needed to teach to achieve this was 0.43.

CONCLUSIONS

An online SE game among clinicians generated a modest but significant reduction in the time to BP target among their hypertensive patients.

Chronic care model as a framework to improve diabetes care at an academic internal medicine faculty-resident practice

We implemented a quality improvement project for diabetes care in a faculty-resident internal medicine practice, using the Chronic Care Model framework. We created a planned visit clinic, used a stepwise medication algorithm, and self-management support. The intervention was effective for patients with glycohemoglobin A1c levels 10 or above (P = .0075) when compared with usual care after adjusting for all significant predictors. Compliance with foot examinations increased by 72% (P < .0001) and pneumococcal vaccinations by 25% (P = .0115). We believe that the Chronic Care Model can be successfully integrated into faculty-resident practices and provides a model for further exploration into disease management education in academic settings.

Current perspectives on psychological insulin resistance: primary care provider and patient views

BACKGROUND

Psychological insulin resistance (PIR) refers to reluctance of providers to prescribe and patients to take insulin. Processes and tools have been developed to address PIR. The purpose of this qualitative study was to examine current understanding and opinions of insulin therapy of primary care providers (PCPs) and patients with type 2 diabetes (both naive to insulin and insulin users).

SUBJECTS AND METHODS

Providers (n=23 PCPs) and patients (n=96) participated in 1:1 interviews and 12 racially/ethnically diverse focus groups, respectively, conducted by trained qualitative researchers using pilot-tested scripts. Participants examined insulin devices and needles while specific questions were asked about insulin therapy. Recorded sessions were transcribed and analyzed.

RESULTS

Salient themes related to injection resistance, patient adherence, health system barriers, and education emerged during the sessions. Provider knowledge about insulin injection devices and approaches varied and was often limited, particularly regarding needle sizes, which influenced prescribing practices and patient education. Other barriers included limited time and personnel. However, PCPs placed priority on continuing education on devices, needles, insulin adjustment, educational approaches, and cost. Patient focus groups revealed a strong desire for knowledge on injection logistics, particularly by insulin users who felt that they had received inadequate education. Most patients had limited experience with tools like shorter needles but would consider injecting if presented. Those who had self-injection experience were more willing to accept insulin. Cost concerns and need for information were frequently reported.

CONCLUSIONS

Findings reveal that programs and tools designed to address problems associated with PIR have yet to be fully realized.

Optimizing insulin pump therapy: the potential advantages of using a structured diabetes management program

Use of continuous subcutaneous insulin infusion (CSII) therapy improves glycemic control, reduces hypoglycemia and increases treatment satisfaction in individuals with diabetes. As a number of patient- and clinician-related factors can hinder the effectiveness and optimal usage of CSII therapy, new approaches are needed to address these obstacles. Ceriello and colleagues recently proposed a model of care that incorporates the collaborative use of structured SMBG into a formal approach to personalized diabetes management within all diabetes populations. We adapted this model for use in CSII-treated patients in order to enable the implementation of a workflow structure that enhances patient-physician communication and supports patients' diabetes self-management skills. We recognize that time constraints and current reimbursement policies pose significant challenges to healthcare providers integrating the Personalised Diabetes Management (PDM) process into clinical practice. We believe, however, that the time invested in modifying practice workflow and learning to apply the various steps of the PDM process will be offset by improved workflow and more effective patient consultations. This article describes how to implement PDM into clinical practice as a systematic, standardized process that can optimize CSII therapy.

The ABC of diabetes. How many patients are able to achieve the goal laid down by American Diabetes Association?

BACKGROUND

To study the number of patients with Type 2 Diabetes Mellitus who achieve the glycemic, blood pressure and LDL-Cholesterol targets as per American Diabetes Association, Standard of Care for Management of Diabetes.

METHODS

Hundred patients of Type 2 Diabetes mellitus were recruited from December 2008 to January 2009 from an Endocrinology OPD of tertiary care hospital and followed up for six months. Glycosylated hemoglobin (HbA1c), blood pressure (BP) and LDL-Cholesterol (LDL) were estimated at baseline and prevalence of those at target (HbA1c <7%, BP < 130/80 mm Hg, LDL < 100 mg/dl) was documented and repeated at three and six months to monitor improvement in the number of patients at target and trend in improvement of individual parameters.

RESULTS

The percentage of patients at target at baseline and six months for HbA1c was (45% vs. 55% p = 0.101), BP < 130/80 mm Hg (27% vs. 25%) and LDL <100 mg/dl (37% vs. 40% p = 0.386). All three parameters were at target in one patient and three patients at six months period. Mean values at baseline and six months of HbA1c 7.46% (95% CI 7.17-7.75) vs 7.21% (95% CI 6.9-7.52), Systolic BP 138 mm Hg (95% CI 135-141), Diastolic BP 86 mm Hg (95% CI 84-86) and LDL 114 mg/dl (95%CI 107-121) vs. 110 mg/dl (95%CI 105-116) did not show significant improvement (p for trend).

CONCLUSION

Standards of care for HbA1c, blood pressure and LDL remains to be achieved in majority of the diabetic patients.

Glycaemic control is harder to achieve than blood pressure or lipid control in Irish adults with type 1 diabetes

We sought to determine the attainment of targets for glycaemic control and vascular risk reduction in an Irish cohort of T1DM adults. Of 797 patients (53% male, mean age 40.3 ± 14.8 years, HbA1c 8.5 ± 1.6% (69.6 ± 17.8 mmol mol(-1))), 15%, 68% and 62% achieved targets for HbA1c, blood pressure and LDL cholesterol, respectively.
