Anti-VEGF treatments provide economic value to patients and society

American Academy of Ophthalmology News Mar 14, 2020

In this study, investigators evaluated the economic value of anti–VEGF treatments for US patients with wet AMD.

Study design

The authors simulated visual outcomes from 168,820 patients age 65 years and older with wet AMD—this was used to calculate economic variables. The main outcomes included patient benefits, costs and societal value at 3 years. Patients were divided into two frequent scenarios: the less frequent group received a mean of 8.2 injections annually while the more frequent group received 10.5 injections annually.

Outcomes

The scenario of less frequent injections generated $1.1 billion at year 1 and $5.1 billion in year 3. More frequent injections generated $1.6 billion in year 1 and $8.2 billion in year 3. The authors found that more frequent injections were associated with $3 billion in patient benefits over a 3-year period, and adherence to treatment led to greater patient and societal value.

Limitations

The authors assume that 100% of patients started anti-VEGF treatment and the discontinuation rate was 6% per year. Patient adherence in real world scenarios may often be less than 6%, and patients may have difficulty coming in more frequently regardless of overall benefit. Additionally, patients may receive less frequent injection in real world scenarios than they did in the less frequent group, as many US physicians treat wet AMD with a treat-and-extend protocol.

Clinical significance

In an accompanying editorial to this article, Melissa Brown, MD, and Gary Brown, MD, go into greater detail about the contributions of more frequent and less frequent treatments to society. Both the authors and the editorial note that more frequent injections incurred higher ophthalmic medical costs; however, these costs were offset by greater patient financial return on investment because of improved visual acuity outcomes. This study adds to the large body of evidence that suggests that the care that ophthalmologists provide has value not only to patients, but to society as a whole.
