The impact of geography on receipt of cancer treatment in Montana.

140 Background: The challenges of cancer patients in rural areas are well-documented. Most rural hospitals do not deliver on-site cancer care services and lack infrastructure, specialty physicians and oncology-trained support personnel (i.e., nurses, advanced practice providers, and pharmacists) to deliver infusion services. Because of this, cancer patients travel long distances to receive treatment. Travel distance is associated with an increased financial burden and worse outcomes with cancer, including later stage at diagnosis, less timely receipt of chemotherapy, and delay or declination of treatment. According to America’s Health Rankings, high geographic disparity within the state of Montana remains a significant challenge to overall health. Chronic understaffing of oncologists further exacerbates the geographic barrier to cancer care. Methods: To assess the impact of these combined access barriers to cancer treatment, we utilized 5 year cumulative data (2014-2018) from the Montana tumor registry database to assess the impact of geographic disparity on cancer care for patients in Montana. Results: Overall 19.2% of Montanans did not receive treatment following a cancer diagnosis. This is similar to the percentage of cancer patients in Delaware that did not receive treatment (19.1%). Although the population of Delaware is similar to Montana, it is 1.3% of the size. While this suggests that distance may not impact the receipt of treatment for cancer, further analysis of treatment data for Montana by county demonstrated broad discrepancies in the receipt of treatment: No treatment ranged from 12.5% to 30.3%. When mapped geographically the counties with the highest percentage of “no treatment” were distant from the 8 Commission on Cancer-approved cancer centers within the state. A similar county-by-county analysis demonstrated no apparent relationship of “no treatment” with either socioeconomic deprivation or lack of insurance. Distance from Commission on Cancer-approved centers also correlated with traveling out of state to receive care. Conclusions: This analysis provides insight into the impact of geographic barriers on cancer treatment in Montana and identifies remote sites that could benefit from robust outreach and care services to improve cancer care delivery.
