Associations between healthcare costs and care experiences among older adults with and without cancer.

INTRODUCTION:Care coordination and patient-provider communication are important for older adults with cancer, as they likely have additional, non-cancer chronic conditions requiring consultation across multiple providers. Suboptimal care coordination and patient-provider communication can lead to costly and preventable adverse outcomes. This study examines Medicare expenditures associated with patient-reported care coordination and patient-provider communication among older adults with and without cancer. MATERIALS AND METHODS:We explore SEER-CAHPS® (Surveillance, Epidemiology and End Results-Consumer Assessment of Healthcare Providers and Systems) linked data for differences in health care expenditures by care coordination and patient-provider communication experiences for beneficiaries with and without cancer. The cancer cohort included beneficiaries with ten prevalent cancer types diagnosed 2011-2019 at least six months before completing a CAHPS survey. Medicare expenditures were abstracted from Medicare claims data. Care coordination and patient-provider communication composite scores (range 0-100, higher scores indicate better experiences) were patient-reported in the CAHPS® survey. We estimated expenditure differences per one-point change in composite scores for patients with and without cancer. RESULTS:Our analysis included 16,778 matched beneficiaries with and without a previously diagnosed cancer (N = 33,556). Higher care coordination and patient-provider communication scores were inversely associated with Medicare expenditures among beneficiaries with and without cancer in the six months prior to survey response, ranging from -$83 (standard error [SE] = $7) to -$90 (SE = $6) per month. Six months post-survey, expenditures estimates ranging -$88 (SE = $6) to -$106 (SE = $8) were found. DISCUSSION:We found that lower Medicare expenditures were associated with higher care coordination and patient-provider communication scores. As the number of survivors living longer both with and beyond their cancer grows, addressing their multifaceted care and improving outcomes will be critical.
