Pen needle use patterns in an insured population with diabetes: US retrospective claims analysis.

BACKGROUND: People with diabetes who inject insulin with pen devices may reuse the pen needles (PNs), a practice that can cause PN tip deformity, breakage, and contamination, and that is associated with lipohypertrophy and injection-related pain. OBJECTIVE: This retrospective study aimed to estimate the extent of PN reuse among people with diabetes in two insured populations in the United States. METHODS: Using claims data for Commercial Fully Insured (CFI) and Medicare Advantage (MA) populations from 1-Oct-2018 to 31-Dec-2022, we identified adults with type 1 or type 2 diabetes (T1D/T2D) who had ≥1 claim for PNs and ≥2 claims for insulin from 1-Jan-2019 to 31-Dec-2021, with continuous medical/pharmacy eligibility for 3 months before first claim and 1 year after (follow-up). Those receiving hospice or palliative care or using mail-order prescriptions were excluded. We compared actual annual fill rate of PNs with expected fill rate (assuming single use) according to prescribed insulin regimen. Whether the annual actual-to-expected ratio for PN numbers equaled 1 was evaluated using sign tests with 2-sided p-values. RESULTS: Median annual actual-to-expected ratios ranged from 0.41 (T1D basal+prandial cohort) to 0.82 (T2D basal cohort; all p<0.001) in the CFI population (N=10,854), and from 0.55 (TID basal+prandial) to 1.10 (T2D basal and basal+prandial; p=0.382 to <0.001) in the MA population (N=32,495); medians were 0.34 and 0.55 for four expected T2D basal+prandial injections/day in CFI and MA populations, respectively (p<0.001). Annual actual-to-expected ratios were <1 for 62% and 47% of CFI and MA populations, respectively. An estimated 2-27% and 0-17%, respectively, depending on insulin regimen, had inadequate supplies of PNs suggesting that PNs could have been used ≥5 times. CONCLUSIONS: These findings highlight the need for educating people with diabetes about reasons for avoiding PN reuse and the key role that pharmacists can play in providing this information and adequate supplies of PNs.

Diabetes, Part 1: Disease State Review.

The art and science of diabetes care, education, and management has evolved significantly over the last few decades. Yet, the United States is experiencing an escalation in the number of diabetes cases. Diabetes is a highly prevalent health condition in the aging population with more than 9 million (26.8%) people 65 years of age and older having diabetes and over 50% with pre-diabetes. In older patients, it is imperative to know the type of diabetes a person has is accurately diagnosed to ensure the correct treatment is used. Pharmacists need to individualize treatment goals and develop optimal therapy plans that focus beyond glycemic management and consider cardiovascular (CV), renal, weight, and hypoglycemic risks and benefits for effective and efficacious care in older patients.

A review of GLP-1 receptor agonists in type 2 diabetes: A focus on the mechanism of action of once-weekly agents.

WHAT IS KNOWN AND OBJECTIVE: Glucagon-like peptide-1 receptor agonists (GLP-1 RAs) are one of the preferred approved treatment options for people with type 2 diabetes (T2D) and inadequate glycaemic control. The objective of this review is to provide a general clinical overview of the similarities and differences in the mechanisms of action (MoA) of the once-weekly GLP-1 RA class of medications, highlighting the role of pharmacists in providing optimal medication management, education and care for people with diabetes. METHODS: This is a narrative review of the published literature regarding the MoA of the currently available once-weekly GLP-1 RAs in T2D. RESULTS AND DISCUSSION: GLP-1 RAs have an established efficacy and safety profile. Their benefits derive from their blood glucose-lowering effects, which include pancreatic beta-cell-mediated glucose-dependent insulin secretion and suppressed glucagon release, and their ability to slow gastric emptying and promote satiety. GLP-1 RAs may also exert beneficial effects on multiple organ systems in which GLP-1 receptors are present, including the cardiovascular and renal systems. Differences between individual GLP-1 RAs with regard to their molecular size, structure and duration of action (short or longer acting) have led to differing pharmacodynamics and clinical effects such as degree of glycaemic control, weight loss abilities, cardiovascular effects and tolerability profiles. WHAT IS NEW AND CONCLUSION: From the literature, this appears to be the first review of the evidence base supporting the MoA of once-weekly GLP-1 RAs in T2D aimed at pharmacists, with a particular emphasis on the expanding role of pharmacists in team-based diabetes management. As a class, GLP-1 RAs are an effective treatment option for people with T2D, shown to achieve multi-factorial clinical benefits. The results suggest that when selecting or advising about treatments, pharmacists should consider how the different once-weekly GLP-1 RAs and their MoA affect clinical outcomes in order to ensure optimal treatment for individuals.

Comparison of the diabetes guidelines from the ADA/EASD and the AACE/ACE.

OBJECTIVE: To compare recent diabetes guideline updates from the American Diabetes Association-European Association for the Study of Diabetes (ADA/EASD) and the American Association of Clinical Endocrinologists-American College of Endocrinology (AACE/ACE). SUMMARY: The ADA/EASD guideline continues to advocate a stepwise approach to glycemic control that initiates with metformin and intensifies treatment incrementally to dual and triple therapy at 3-month intervals until the patient is at their individualized goal. The AACE/ACE guideline provides a broader choice of first-line medications, with a suggested hierarchy of use, and it encourages initial dual and triple therapy if the glycated hemoglobin (A1C) level is high enough at diagnosis (7.5%-9.0% and >9.0%, respectively). Target A1C levels are higher in the ADA/EASD guideline (≤7.0%) compared with the AACE/ACE guideline (≤6.5%), although both statements indicate that targets should be adjusted to specific clinical scenarios based on safety. Both guidelines now include the new sodium-glucose cotransporter-2 inhibitors among their choices of acceptable glucose-lowering medications and endorse the overall cardiovascular and pancreatic safety of incretin therapies, and the safety of pioglitazone vis-a-vis bladder cancer. CONCLUSION: In practice, the ADA/EASD guidelines tend to be more user-friendly for general practitioners because of the simple stepwise intensification regimen, whereas the AACE/ACE guidelines are more commonly followed by specialists (endocrinologists) because of the more aggressive A1C targets.

Canagliflozin Treatment in Patients with Type 2 Diabetes Mellitus.

Current guidelines for treatment of type 2 diabetes mellitus (T2DM) indicate a patient-centered approach that should go beyond glycemic control. Of the many antihyperglycemic agents available for treatment of T2DM, sodium-glucose cotransporter 2 (SGLT2) inhibitors offer the advantages of reduced glycated hemoglobin (A1C), body weight (BW), and systolic blood pressure (SBP) and are associated with a low risk of hypoglycemia when used either as monotherapy or with other agents not typically associated with increased risk of hypoglycemia. Collaborative, multidisciplinary teams are best suited to provide care to patients with diabetes, and clinical pharmacists can enhance the care provided by these teams. This review aims to provide insight into the mode of action, pharmacology, potential drug-drug interactions, clinical benefits, and safety considerations associated with use of the SGLT2 inhibitor canagliflozin in patients with T2DM and to provide information to enhance clinical pharmacists' understanding of canagliflozin.

Continual evolution of type 2 diabetes: an update on pathophysiology and emerging treatment options.

Diabetes is a complex and progressive disease that has a major societal and economic impact. The most common form of diabetes, type 2 diabetes mellitus (T2DM), is a multifactorial disease, the pathophysiology of which involves not only the pancreas but also the liver, skeletal muscle, adipose tissue, gastrointestinal tract, brain, and kidney. Novel therapies with mechanisms of action that are different from most existing drugs are emerging. One such class consists of compounds that inhibit renal sodium-glucose cotransporter 2, which is responsible for the bulk of glucose reabsorption by the kidneys. This new class of compounds improves glycemic control independently of insulin and promotes weight reduction, providing an additional tool to treat patients with T2DM. This review discusses the underlying pathophysiology of T2DM, clinical guidelines, and available and emerging treatment options, with particular emphasis on sodium-glucose cotransporter 2 inhibitors.

Review of empagliflozin monotherapy for previously untreated patients with type 2 diabetes mellitus: Comparison with sitagliptin.

This Practice Pearl provides a review and brief commentary of the 24-week, double-blind, parallel-group, randomized, Phase III study by Roden et al., which assessed the efficacy and safety of the sodium-glucose cotransporter 2 inhibitor empagliflozin, 10 mg or 25 mg as monotherapy, versus placebo and the dipeptidyl peptidase-4 inhibitor sitagliptin, in previously untreated patients with type 2 diabetes mellitus (T2DM). Compared to placebo, empagliflozin improved glycemic control, with additional benefits on bodyweight and systolic blood pressure, versus placebo and sitagliptin. Treatment was well tolerated. The authors concluded that empagliflozin is a potential new approach to treat patients with T2DM who are inadequately controlled with diet and exercise alone. This paper advances our understanding of empagliflozin, which so far, appears to be a promising therapeutic option for the management of patients with T2DM.

Pharmacotherapy considerations in diabetes and obesity: setting patients up for success.

The causal relationship between obesity and type 2 diabetes mellitus has been acknowledged over the past few decades and is frequently expressed by the term diabesity. It is predicted that the number of people with diabetes mellitus (DM) and prediabetes will continue to rise, with obesity placing people at increased risk for diabetic complications and comorbidities. Therefore, an individualized, patient-centered care approach is needed to optimally treat and manage the obese patient with DM. With 11 classes of medications available to lower blood glucose levels, 2 new agents for weight loss, and various surgical procedures, the clinician and the patient have numerous options from which to choose. In an effort to promote optimal disease management, clinicians should work with their obese patients to select appropriate pharmacotherapy combinations that will enable the patients to successfully manage DM. The current clinical recommendations and guidelines emphasize the need to consider the weight effects of the various DM agents as monotherapy and in combination. Additionally, with the approval of 2 new weight loss medications, the clinician must be aware of the place of the medications in therapy and their appropriate use in combination with DM pharmacotherapy.

Critical thinking and reflection exercises in a biochemistry course to improve prospective health professions students' attitudes toward physician-pharmacist collaboration.

OBJECTIVE: To determine the impact of performing critical-thinking and reflection assignments within interdisciplinary learning teams in a biochemistry course on pharmacy students' and prospective health professions students' collaboration scores. DESIGN: Pharmacy students and prospective medical, dental, and other health professions students enrolled in a sequence of 2 required biochemistry courses. They were randomly assigned to interdisciplinary learning teams in which they were required to complete case assignments, thinking and reflection exercises, and a team service-learning project. ASSESSMENT: Students were asked to complete the Scale of Attitudes Toward Physician-Pharmacist Collaboration prior to the first course, following the first course, and following the second course. The physician-pharmacist collaboration scores of prospective health professions students increased significantly (p<0.001). CONCLUSIONS: Having prospective health professions students work in teams with pharmacy students to think and reflect in and outside the classroom improves their attitudes toward physician-pharmacist collaboration.

A patient-centred approach to treatment with incretin-based agents in patients with type 2 diabetes.

WHAT IS KNOWN AND OBJECTIVE: The 2012 position statement from the American Diabetes Association (ADA) and the European Association for the Study of Diabetes (EASD) recommends a haemoglobin A1c level of <7% for most patients with type 2 diabetes (T2D). Initial therapy consists of lifestyle changes plus metformin, with an emphasis on a patient-centred approach to management. Addition of incretin-based therapy is recommended as an add-on after metformin failure, and later on in combination with basal insulin. Basal insulin is recommended from the onset in patients with A1c ≥10%. The possibility of incorporating incretin-based therapy in the patient-centred approach will be investigated both in the literature and clinical experience. COMMENT: Incretin-based therapy targets multiple dysfunctional organ systems in T2D and provides sustained glycaemic control, with extraglycaemic benefits and low risk of hypoglycaemia. To initiate an incretin-based therapy that best fits an individual patient's needs, the patient's A1c level, preference and comorbid conditions should be considered along with any drug safety and adherence-related issues. WHAT IS NEW AND CONCLUSION: There is good evidence to support the patient-centred approach to T2D management. This approach allows patient treatment goals and personal preferences to be matched with the clinical profile(s) of one or more agents to formulate a treatment plan that can best achieve the goals. Incretin-based therapies are an important class of agents to consider after metformin monotherapy failure and later in combination with basal insulin. By matching patient needs with the clinical profiles of the various treatment options, pharmacists can actively engage in the practice of patient-centred care and management.

Interprofessional workshop to improve mutual understanding between pharmacy and medical students.

OBJECTIVE: To measure changes in pharmacy and medical students' physician-pharmacist collaboration scores resulting from a workshop designed to promote understanding of the others' roles in health care. METHODS: More than 88% of first-year pharmacy (n = 215) and medical (n = 205) students completed the Scale of Attitudes Toward Physician-Pharmacist Collaboration on 3 occasions in order to establish a baseline of median scores and to determine whether the scores were influenced by an interprofessional workshop. RESULTS: Participation in the interprofessional workshop increased pharmacy students' collaboration scores above baseline (p=0.02) and raised the scores of medical students on the education component of the collaboration survey instrument (p=0.015). The collaboration scores of pharmacy students greatly exceeded those of medical students (p<0.0001). CONCLUSION: A workshop designed to foster interprofessional understanding between pharmacy and medical students raised the physician-pharmacist collaboration scores of both. Crucial practical goals for the future include raising the collaboration scores of medical students to those of pharmacy students.

Diabetes pharmacotherapy in 2012: considerations in medication selection.

Diabetes is one of the most costly and burdensome chronic diseases, and its therapy and management have become increasingly complex. The incidence of type 2 diabetes mellitus (T2DM), a multiorgan disorder, is increasing at an epidemic rate in the United States and worldwide. Despite numerous scientific and medical advances, less than half of the population with T2DM has achieved the American Diabetes Association-recommended glycated hemoglobin level goal of < 7%, which is necessary to optimally manage the disease to prevent and minimize complications. There are many patient- and clinician-determined barriers that hinder patients from achieving target blood glucose levels. Therefore, it is imperative for health care professionals who treat patients with T2DM (and those at risk for developing T2DM) to have an enhanced knowledge base of the current pathophysiology, treatment options, and clinical guidelines for T2DM and its related conditions.

Managing diabetes-related costs and quality of life issues: Value of insulin analogs and pens for inpatient use.

Diabetes mellitus is a serious disease that is growing at an epidemic rate, yet it can be managed and controlled with appropriate individualized therapy. In the hospital, costs can be reduced and health-related quality of life (HRQOL) improved by optimal glycemic and blood pressure control, minimal or no hypoglycemia, minimal glucose fluctuations, fewer or no complications, and a shorter length of stay. Insulin analogs and pens are tools that have been used successfully to manage hyperglycemia in the inpatient and outpatient settings. Limited evidence suggests that these advances in insulin therapy may increase HRQOL and improve cost-effectiveness in hospitalized patients compared with regular and NPH insulin and vial/syringe administration of insulin, although additional data are needed to confirm these findings. Most insulin algorithms used in hospitals rely on analogs for basal and prandial glucose control; however, analogs have not been extensively evaluated in clinical trials in this patient population. More studies are needed to evaluate the impact of insulin pen and analog use on HRQOL and costs in hospitalized patients.

Clinical case study: achieving long-term control of insulin resistance.

BACKGROUND: A total of 20.8 million people in the United States have diabetes, including 10.3 million adults over the age of 60 years, and more than 6 million people remain undiagnosed. Although diabetes is widely recognized as a prevalent and serious disease in managed care, current care is suboptimal, with less than 2% of American adults with diabetes receiving optimal quality of care. OBJECTIVE: To review the various treatment interventions available in diabetes care, including the use of pay for performance (P4P) initiatives. SUMMARY: In an effort to improve the current state of diabetes care, the NCQA's Health Plan Employer Data and Information Set (HEDIS) diabetes measure was developed as a means to better promote monitoring of various clinical markers in patients with this disease. This measure has been employed in P4P initiatives across the country by granting incentives to providers who have a prespecified proportion of their patients with diabetes meeting the measure. Likewise, to improve outcomes, many experimental and recently approved treatment options for diabetes target different processes in the course of the disease. CONCLUSIONS: An effective program for the management of a diabetes patient population must be multidisciplinary, coordinating the efforts of many different levels of health care providers. Furthermore, components commonly incorporated in P4P initiatives, such as patient self-management education, provider contact, and the use of the American Diabetes Association standards of care measures for screening and lab levels, are imperative to the success of a diabetes management program.
