  • Travel burden and bypassing closest site for surgical cancer treatment for urban and rural oncology patients

    Open Access•Tracy Onega, Niveditta Ramkumar et al.•ARTICLE•The Journal of Rural Health•2025

    PURPOSE: We examined the relationship between travel burden for surgical cancer care and rurality, geographic bypass of the nearest surgical facility, cancer type, and mortality outcomes. METHODS: Using Medicare claims and enrollment data (2016-2018) from beneficiaries with cancer of the colon, rectum, lung, or pancreas, we measured travel times to: the nearest surgical facility and facility used. For those who bypassed the nearest, we examined t…

  • Association of rurality with utilization of palliative care and hospice among Medicare beneficiaries who died from pancreatic cancer

    Open Access•Niveditta Ramkumar, Qianfei Wang et al.•ARTICLE•The Journal of Rural Health•2023

    BACKGROUND: Pancreatic cancer has a 5-year survival of just 10%. Services such as palliative care and hospice are thus crucial in this population, yet their geographic accessibility and utilization remains unknown. AIM: We studied the association between rurality of patient residence and the use of palliative care and hospice. DESIGN, SETTING, AND PARTICIPANTS: Cohort study of continuously enrolled fee-for-service Medicare beneficiaries aged ≥65 …

  • The interaction of rurality and rare cancers for travel time to cancer care

    Open Access•Tracy Onega, Jennifer Alford‐Teaster et al.•ARTICLE•The Journal of Rural Health•2023

    PURPOSE: Geographic access to cancer care is known to significantly impact utilization and outcomes. Longer travel times have negative impacts for patients requiring highly specialized care, such as for rare cancers, and for those in rural areas. Scant population-based research informs geographic access to care for rare cancers and whether rurality impacts that access. METHODS: Using Medicare data (2014-2015), we identified prevalent cancers and …

  • Association of Cost Sharing With Delayed and Complicated Presentation of Acute Appendicitis or Diverticulitis

    Open Access•Andrew P Loehrer, Mary M Leech et al.•ARTICLE•JAMA Health Forum•2021

    The findings of this cohort study suggest that, as policymakers debate the degree of cost sharing in public and private insurance plans, attention should be given to the clinical and financial implications associated with care delays
