In support of National Kidney Month this March, IQVIA is helping to raise public awareness by sharing data-driven insights on patient access in chronic kidney disease (CKD). CKD is a disorder in which the kidneys are damaged to the extent that patients cannot filter blood as well as they should. It is a common disease and a leading cause of death in the United States. Many patients who suffer from this disease remain undiagnosed or untreated, subsequently costing the U.S. healthcare system billions of dollars annually.

CKD by the Numbers1

  • Kidney diseases are a leading cause of death in the United States.
  • About 37 million U.S. adults are estimated to have CKD, and most are undiagnosed.
  • 40% of people with severely reduced kidney function are not aware of having CKD.
  • Every 24 hours, 360 people begin dialysis treatment for kidney failure.
  • In the United States, diabetes and high blood pressure are the leading causes of kidney failure, representing about 3 out of 4 new cases.
  • In 2019, treating Medicare beneficiaries with CKD cost $87.2 billion, and treating people with End-Stage Renal Disease (ESRD) cost an additional $37.3 billion.
  • Compared to patients with Type II Diabetes (T2D) alone, patients who have CKD associated with T2D reported twice as many Myocardial Infarction cases2 and have an 83% greater risk of Cardiovascular related death.3

Early detection and treatment make a difference

As patients progress through stages of chronic kidney disease, the annual cost of treatment increases substantially. Stage 2 CKD patients, on average, require roughly double the treatment costs of non-CKD patients. For patients in End-Stage Kidney Disease (ESKD) without dialysis, the cost of treatment is more than 10 times of those with CKD. Earlier diagnosis and treatment not only lead to better quality of life for patients, but also reduce the overall cost of treatment by slowing disease progression.4

Patients with CKD and Type 2 Diabetes (T2D) are at greater risk

For many patients, high blood pressure and diabetes lead to heightened risk of developing CKD and escalated overall healthcare costs. For patients under the age of 65 with both CKD and T2D, the cost of treatment can be as much as 60% higher than treating T2D alone, while having a meaningful impact on quality of life.5 Despite the known correlations and higher annual treatment costs, there remain many gaps in care for patients. This causes substantial portions of the population to remain undiagnosed.

According to the CDC, 9 out of 10 adults with CKD do not know they have CKD.6 Inequities and disparities in awareness, testing, diagnosis, and intervention may be more prominent at certain points in the patient journey. For instance, Native American, Black, and Hispanic patients have high rates of diabetes,7 which increases the risk of developing CKD.8

By 2060, the diabetes population in the U.S. is expected to double to over 60 million patients,9 with up to 40%10 also suffering from CKD, many of whom will remain undiagnosed. Building and investing in treatment protocols, supporting patient organizations, and more is needed to bridge known health disparities and the overall undertreatment of CKD. Utilizing IQVIA’s Longitudinal Access and Adjudication Data (LAAD), a recent analysis of CKD in T2D treatments, Kerendia (finerenone) and SGLT2is, showed that 94% of diabetes patients who are also diagnosed with CKD are not gaining access to such newer therapies indicated to reduce risks of renal and cardiovascular outcomes associated with CKD, and are thus, not benefitting from available treatments.11

Payer controls can have unintended consequences

The IQVIA analysis also demonstrated that 35% of all Kerendia new-to-brand patients – and only 29% of Medicare Part D patients – were able to fill their prescriptions and begin therapy. The largest obstacle preventing these patients from obtaining treatment was payer access control, which more than half of patients were unable to overcome. The impact of payer restrictions was observed across all payer channels, including Medicare Part D and Commercial, which includes private insurance through employers and the healthcare exchanges. Analyzing patients not already on an SGLT2i, IQVIA determined that more than 90% of patients who initially received a payer rejection for Kerendia were not subsequently treated with an SGLT2i as an alternative within a 90-day period.11 Therefore an unintended consequence of payer controls may not only be a delay in treatment but a lack of intervention overall.

Conclusion

CKD is a costly disease for patients, payers, and society as a whole. As patients progress through the stages of the disease, annual cost of treatment increases while quality of life declines. Despite the known linkages between T2D and CKD, up to 90% of patients remain undiagnosed. Within minority populations, where chronic disease prevalence is even higher, there remains a gap in the journey to treatment. Given the progressive and irreversible nature of CKD, there is a clear population health need for early diagnosis and treatment. Analysis of payer controls, however, indicates that access barriers are a necessary factor for consideration when addressing this need.

Once patients have navigated the healthcare system to treatment, there are additional barriers faced in payer coverage which can have unintended consequences. In a disease area where untreated patients will face a heightened risk of disease progression, the balance of patient access and healthcare costs is particularly crucial.
