Background
Cost-related non-adherence (CRN) is prevalent among individuals with diabetes and can have significant negative health consequences. We examined health and non-health-related pressures and the use of cost-reducing strategies among the U.S. adult population with and without diabetes that may impact CRN.
Methods
Data from the 2013 wave of National Health Interview Survey (n=34,557) were used to identify the independent impact of perceived financial stress, financial insecurity with healthcare, food insecurity, and cost-reducing strategies on CRN.
Results
11% (n=4,158) of adults reported diabetes. 14% with diabetes reported CRN, compared to 7% without. Greater perceived financial stress (Prevalence Ratio (PR)=1.07 [95% CI: 1.05 to 1.09]), financial insecurity with healthcare (PR=1.6 [95% CI: 1.5 to 1.67]), and food insecurity (PR=1.30 [95% CI: 1.2 to 1.4]) were all associated with a greater likelihood of CRN. Asking the doctor for a lower cost medication was associated with a lower likelihood of CRN (PR=0.2 [95% CI: 0.2 to 0.3]), and 27% with CRN reported this. Other cost-reducing behavioral strategies (using alternative therapies, buying prescriptions overseas) were associated with a greater likelihood of CRN.
Conclusions
Half of adults with diabetes perceived financial stress, and one-fifth reported financial insecurity with healthcare and food insecurity. Talking to a health care provider about low-cost options may be protective against CRN in some situations. Improving screening and communication to identify CRN and increase transparency of low-cost options patients are pursuing may help safeguard from the health consequences of cutting back on treatment.
