Abstract

Background

Evidence suggests that high-volume facilities achieve better rectal cancer outcomes.

Methods

Logistic regression was used to evaluate association of facility type with treatment after adjusting for patient demographics, stage, and comorbidities. SEER-Medicare beneficiaries who were diagnosed with stage II/III rectal adenocarcinoma at age ≥66 years from 2005 to 2009 and had Parts A/B Medicare coverage for ≥1 year prediagnosis and postdiagnosis plus a claim for cancer-directed surgery were included. Institutions were classified according to National Cancer Institute (NCI) designation, presence of residency program, or medical school affiliation.

Results

Two thousand three hundred subjects (average age = 75) met the criteria. Greater proportions of those treated at NCI-designated facilities received transrectal ultrasound (TRUS) or magnetic resonance imaging (MRI)-pelvis (62.1 vs. 29.9 %), neoadjuvant chemotherapy (63.9 vs. 41.8 %), and neoadjuvant radiation (70.8 vs. 46.3 %), all p < 0.0001. On multivariate analysis, odds ratios (95 % confidence intervals) for receiving TRUS or MRI, neoadjuvant chemotherapy, or neoadjuvant radiation among beneficiaries treated at NCI-designated facilities were 3.51 (2.60–4.73), 2.32 (1.71–3.16), and 2.66 (1.93–3.67), respectively. Results by residency and medical school affiliation were similar in direction to NCI designation.

Conclusions

Those treated at hospitals with an NCI designation, residency program, or medical school affiliation received more guideline-concordant care. Initiatives involving provider education and virtual tumor boards may improve care.
