260 Background: As cancer-related health care expenses are increasing, a greater proportion of treatment costs are shifting directly to the patient, resulting in an increased financial burden for many patients. In addition to growing healthcare costs, the inflationary environment in the US has also increased the costs of daily living expenses. Although the Inflation Reduction Act (IRA) encompasses measures for negotiating prices of specific high-cost medications within Medicare Parts B and D, given the expenses associated with cancer treatment IRA negotiation provisions will likely have limited impact on patients’ financial burden. We sought to capture the financial and emotional experiences of Medicare cancer patients about their costs of care prior to the implementation of the IRA. Methods: This cross-sectional analysis used data from a nationwide survey distributed in February 2024 by Patient Advocate Foundation (PAF). Inclusion criteria included a valid email address, age >19, self-reported cancer diagnosis and Medicare coverage. Frequencies were calculated for categorical variables. Additional information about financial challenges will be collected on a subset of cancer survey respondents in May 2024. Results: A total of 331 survey respondents with cancer completed the survey. Most respondents were female (61%), age≥56 (86%), white (73%), retired (59%), married (47%), household income <$48,000 (69%), and rural location (24%). The most common cancer types were multiple myeloma (47%) and breast (26%); 25% were diagnosed < 2 years prior, 87% were receiving cancer treatment and 52% experienced financial challenges prior to diagnosis. Almost half (45%) reported a negative change in their financial situation in the past 12 months; caused by increased living (63%), food (60%), medical care (47%) and medication (39%) costs. Overwhelming/above average financial stress (40%) was reported on the day of the survey; 30% reported spending at least 25% of their monthly income on medical costs; 69% reported financial burden due to their illness. Fifty-nine percent reported that finances impacted their emotional wellbeing. Common coping strategies to alleviate financial distress included positive attitudes, family/friend support and spiritual beliefs. Conclusions: To mitigate the impact of inflation on low-income cancer patients, it is essential for policymakers, healthcare providers, and community organizations to work together to ensure access to affordable healthcare, support services, and financial assistance programs. Additionally, raising awareness about the challenges faced by this vulnerable population and advocating for policies that address their needs can help alleviate some of the burdens imposed by inflation. While the IRA is a step in the right direction, its financial impact on patients appears limited.
