Surveillance for colorectal cancer survivors in an integrated safety-net health system in the United States.

INTRODUCTION

Guideline-recommended surveillance reduces likelihood of colorectal cancer (CRC) recurrence, yet surveillance rates are low in the United States (US). Little is known about CRC surveillance rates among patients without health insurance and their primary care clinicians/oncologists' attitudes towards surveillance care.

METHODS

A retrospective study of 205 patients diagnosed with Stage I-III CRC from 2008-2010 was conducted in an integrated system with a network of providers delivering care to patients lacking health insurance coverage. Surveillance patterns were characterized from medical records and logistic regression models examined correlates of guideline-concordant surveillance. 41 Parkland primary care physicians (PCPs) and 24 oncologists completed surveys to assess their attitudes and practices regarding CRC surveillance.

RESULTS

38% of CRC patients received guideline-concordant surveillance; those with early stage cancers were less likely to receive surveillance (OR=0.35; 95 CI: 0.14, 0.87). PCPs and oncologists differed markedly on who is responsible for cancer surveillance care. 77% of oncologists responded that PCPs evaluated patients for cancer recurrence while 76% of PCPs responded that these services were either ordered by oncologists or shared with PCPs. 67% of oncologists said they rarely provide a treatment and surveillance care plan to survivors and over half said that they infrequently communicate with patients' other physicians about who will follow patients for their cancer and other medical issues.

DISCUSSION

Care coordination between PCP and oncologist is needed to improve CRC surveillance. New models of shared care clearly delineating roles for oncologists and PCPs are needed to improve CRC survivorship care.
