65+: Colorectal cancer screening--blood stool test
Definition: Percentage of people aged 65 and over who had a blood stool test for colorectal cancer screening within the past two years, two-year average
Notes: The data are from Behavioral Risk Factor Surveillance Survey (BRFSS). Respondents were asked the questions: "A blood stool test is a test that may use a special kit at home to determine whether the stool contains blood. Have you ever had this test using a home kit?" and "How long has it been since you had your last blood stool test using a home kit?" These questions were asked every odd year of the survey before 2001, and every even year since 2002. Percentage is a 2-year average, which helps to reduce the year-to-year fluctuation due to small numbers. Percentage is reported under the year at the midpoint of the 3-year period; e.g., the average of 1999 and 2001 was reported under 2000. National data is the median of the 50 states and the District of Columbia.
