Patients with glaucoma report higher levels of cost-related nonadherence
Patients with glaucoma are more likely to report cost-related nonadherence compared with patients without glaucoma, according to research published in Ophthalmology Glaucoma.
Researchers included responses from patients aged 40 and older who responded to questions pertaining to eye health and visual function in the cross-sectional study.
In total, 40,380 participants were included in the survey, where 1,930 patients reported having glaucoma and 38,450 reported not having glaucoma. Patients with glaucoma were more likely to be female, Black, have at least one other medical comorbidity, lower levels of education, lower household income and vision impairment (P < .001).
Patients with glaucoma (8.2%) were more likely to report cost-related nonadherence than patients without glaucoma (6.4%) (P = .024). Of all patients with glaucoma, 22.6% reported asking for cheaper medications.
“In our nationally representative study, we found 8.2% of patients with glaucoma reported they could not afford their medications. Patients may also skip, take less or delay refills for prescribed medications,” Divakar Gupta, MD, one of the study co-authors told Healio/OSN.
Gupta and colleagues used the 2016 to 2017 National Health Interview Survey to determine the rates of cost-related nonadherence.
“Eye professionals that take care of patients with glaucoma should be aware that the cost of medications may influence their patients' ability to adhere to therapy,” Gupta said.
Patient responses did not include disease severity or patient perception details, “both of which may influence the value individuals place on their glaucoma medications, which may in turn affect cost-related medication adherence issues,” the authors wrote.
