Impact of socioeconomic status on cancer care in Southeast Texas: a retrospective population-based cohort study.

BACKGROUND

Gastrointestinal (GI) cancers are the third leading cause of cancer-related mortality worldwide. Disparities in healthcare frequently stem from variations in socioeconomic status (SES). This study investigated the influence of socioeconomic factors such as gender, race, age, and geography on time to treatment initiation (TTI) and survival outcomes.

METHODS

The study analyzed SES data, including age, race, geography, and insurance status, from GI cancer patients treated at Baptist Hospitals of Southeast Texas (BHSET) from 2012 to 2017. Logistic regression was performed for risk association. The primary outcomes were survival time and TTI.

RESULTS

Of 517 GI cancer patients, 359 had colorectal cancer. African Americans had higher treatment delays (odds ratio [OR]: 5.89, confidence interval [CI]: 4.02-8.62) than Caucasians (OR: 0.16, CI: 0.11-0.23). Patients >80 years had poorer survival (OR: 2.91, CI: 1.80-4.72) than younger ones. Those living 30 + miles from BHSET had longer TTI (OR: 1.85, CI: 1.19-2.87), especially within the colorectal cancer cohort (OR: 2.20, CI: 1.29-3.74). Medicare Advantage was linked to longer TTI (OR: 1.50, CI: 1.01-2.23). Medicare patients without supplemental insurance had lower survival overall (OR: 1.79, CI: 1.05-3.06) and among colorectal cancer patients (OR: 2.13, CI: 1.14-3.98).

CONCLUSION

Addressing SES disparities and implementing targeted interventions is imperative to ensure equitable access to timely and effective cancer care.
