Influence of patient characteristics on provider surveillance for colorectal cancer.

Abstract

10071 Background: The majority of colorectal cancer (CRC) patients present with resectable disease and benefit from future resection of second primary CRC, local recurrence, and oligometastases. Therefore, in addition to colonoscopy one year after diagnosis, American Society of Clinical Oncology (ASCO) offers consensus recommendations to monitor serum CEA and CT scans for early detection. Limited adherence to guidelines has been reported; we explore the impact of specific patient factors related to CRC on provider prescribing in the first year. Methods: At a single urban safety-net hospital, electronic medical records of patients diagnosed with stages I-III CRC from 2002-2014 were reviewed with IRB approval. Chi-square tests determined extent of associations between categorical variables. Two sample t-tests compared means for continuous outcomes across groups. Cut-off for Type 1 error was alpha = 0.05. Due to minimal change in surveillance guidelines, we applied ASCO 2005 recommendations. Results: Records for 357 patients included 52% females and 40% African-Americans. Median age was 63 years, ever tobacco abuse was 69%. BMI > 30 found in 38%, median weight at diagnosis was 79 kg. Incidence of surveillance and associated variables are in the Table. Conclusions: The providers of this young, urban, almost 40% obese population were < 50% compliant with first year colonoscopy and < 60% compliant with CEA tests. Providers did significantly survey patients with co-morbidities, such as higher weight at diagnosis, in this small study. Most patients complied with orders and primary care providers were least compliant (data not shown). The data supports verification in larger study of safety-net hospitals and future comparison regarding influence of new Survivorship Care Plans on guideline adherence. To improve provider compliance, etiology of nonadherence must be addressed. [Table: see text]
