Insulin Cost and Underuse in Patients With Diabetes

Costs and underuse of insulin and diabetes supplies: Findings from the 2020 T1International cross-sectional web-based survey

AIMS

To investigate self-reported out-of-pocket expenses (OoPE) associated with insulin and diabetes supplies for people living with type 1 diabetes (T1D) worldwide.

METHODS

A web-based, cross-sectional survey was conducted from August to December 2020. The analysis included comparisons between responses from countries with no, partial, and full healthcare coverage.

RESULTS

1,066 participants from 64 countries took part in the study. ~25% of respondents reported having underused insulin at least once within the last year due to perceived cost. A significant correlation was observed between OoPEs and reported household income for respondents with partial healthcare coverage. 63.2% of participants reported disruption of insulin supplies and 25.3% reported an increase of prices related to the COVID-19 pandemic.

CONCLUSIONS

This study confirms previous reports of ~25% of people in the United States with T1D using less insulin and/or fewer supplies at least once in the last year due to cost, a trend associated with the extent of healthcare coverage. Similar trends were observed in some middle/low income countries. Moreover, patients reported an increase in insulin prices and disruption of supplies during the COVID-19 pandemic. This study highlights the importance of self-reported OoPEs and its association with underuse/rationing of insulin.

Psychometric Analysis Regarding the Barriers to Providing Effective Insulin Treatment in Type 2 Diabetic Patients

INTRODUCTION

A psychometric analysis on type 2 diabetic (T2D) patients was performed to assess whether glycated hemoglobin (HbA1c) levels were dependent upon either the psychologic or economic attitude toward the use of insulin as a treatment for their diabetic condition.

METHODS

A cross-sectional study was designed using 271 patients with T2D who regularly visited a tertiary referral hospital in South Korea from June 2019 to December 2019. Each patient enrolled in this protocol was treated with insulin for at least 6 months, had recordings of their plasma HbA1c measurement, and completed validated questionnaires consisting of items focusing on patient attitudes toward insulin use [Insulin Treatment Appraisal Scale (ITAS)] and cost-related issues related to diabetic supply purchase. Multiple regression analyses were performed to determine the association between their HbA1c and each item on the questionnaires.

RESULTS

In both males and females, there was a significant association (P < 0.05) between HbA1c levels and multiple items on the ITAS questionnaire, which are generally regarded as a negative perception (ITAS 1 "personal failure" and ITAS 2 "illness severity" in males and ITAS 12 "expected harm" and ITAS 15 "restrictiveness" in females). In females, however, not all perceptions were negative, since one item (ITAS 8 "anticipated effect") was correlated with the measurement of a lower HbA1c level (- 0.495 ± 0.211, P < 0.05). There was no association between the levels of HbA1c and the cost of insulin or associated diabetic supplies. Since only a few patients in this study chose to reduce their drug dosing because of cost, the resistance to using insulin is likely not driven by economic reasons.

CONCLUSION

The psychometric results of the ITAS suggested that HbA1c levels were directly associated with a positive attitude of the patient to willingly use insulin for therapy. The cost of the insulin therapy was not associated with HbA1c levels. These findings in the Korean population suggest that continued education is needed to ensure that T2D patients have a reinforced positive psychology toward the use of insulin in the control of their glycemia.

How The ACA Reframed The Prescription Drug Market And Set The Stage For Current Reform Efforts

The Affordable Care Act contained a range of provisions that altered prescription drug access and affordability for patients, payers, and providers. Yet the act stopped short of instituting systemic changes in the pricing of drugs, in part to address concerns that more fundamental changes might disrupt the development of new medicines. Looking back a decade after the Affordable Care Act became law, we found that new drug approvals have accelerated and the therapeutic advances embodied in some novel medicines are substantial-as are the prices that companies are charging for them. The lack of affordability of prescription drugs has become an increasing challenge for American patients and payers, particularly those with limited budgets. In this article we consider how things have changed in the past decade and how missed opportunities in the Affordable Care Act's passage figure prominently in the current drug pricing debate.
