Are care experiences associated with survival among cancer patients?

Abstract

Purpose Cancer patients' care experiences encompass the range of interactions with the health care system and are an important indicator of care quality, which may influence survival outcomes. This study evaluates relationships between care experiences and survival using a large, nationally representative sample of cancer patients. Methods We used linked SEER (Surveillance Epidemiology and End Results)-CAHPS (Consumer Assessment of Healthcare Providers and Systems) data to identify people diagnosed 8/2006-12/2013, focusing on 10 solid tumor cancer sites with the highest mortality rates among those > 65. CAHPS measures included 5 global ratings and 3 composite scores. We used survey-weighted Cox proportional hazard models comparing survival time for those who had lower (0-8) vs higher ratings (9-10) and lower (0-89) vs higher (90-100) composite scores, adjusting for case-mix and additional covariates. Results We identified 2,263 eligible people; 26% died by 5-year post-survey completion or end of follow-up (12/31/2017). We found lower Prescription Drug Plan (PDP) ratings were significantly associated with lower mortality (adjusted HR = 0.67, p = 0.03). Lower Getting Needed Care scores were also significantly associated with lower mortality (adjusted HR = 0.79, p = 0.04). For other care experience measures, general health status, cancer stage, and comorbidities were more predictive of survival (p < .05). Conclusions Except for PDP and Getting Needed Care, survival was similar for those with worse versus better care experiences. Patients with poorer cancer prognoses may perceive better services from their drug plan and more responsive care from clinical providers compared to those with better prognoses. Further research is needed examining processes underlying perceptions of care experiences and survival.
