Referral patterns of Indiana oncologists for colorectal cancer genetic services.

We assessed the utilization and referral patterns of Indiana oncologists for colorectal cancer (CRC) genetic services. Surveys were sent to 151 oncologists practicing within the state, with a response rate of 40%. Half of respondents had previously referred patients for CRC genetic services. Those who had not cited reasons, including absence of an appropriate patient, lack of information about genetic services, and uncertainty regarding which patients to refer. Most were interested in materials that would assist in identifying patients for referral. As a result, a booklet was developed and given to participants. This study demonstrates the need for physician education about CRC genetic services.
