Table 4 Effects of patient level factors on patient fecal occult blood test completion rates

From: Does access to a colorectal cancer screening website and/or a nurse-managed telephone help line provided to patients by their family physician increase fecal occult blood test uptake?: results from a pragmatic cluster randomized controlled trial

  1. 1The Intraclass Correlation Coefficients (ICC) for the medical clinic cluster, family physician, and patient level variables were 0.003, 0.009, and 0.217, respectively.
  2. 2The bolded percentages denote significant differences for each factor.
  3. 3NS = not statistically significant.
  4. 4These factors were obtained from the (pre-visit) In-Clinic Patient Survey [18]. There were significant interactions between each factor and cluster (p < 0.0001) as well as family physician (p < 0.0001).
  5. *Determined by multi-level logistic regression. FOBT completion rate frequency converted from logit scale for the factor treatment are 0.61for the control and 0.69 for intervention groups (p < 0.02); for the factor patient gender are 0.65 and 0.66 for control and intervention groups, respectively (NS); For patient age are 0.53, 0.60, 0.66, 0.73 and 0.72 for the age categories 50 to 54, 55 to 59, 60 to 64, 65 to 69, and 70 to 74, respectively (p < 0.0001); for the survey question “Have you ever done an FOBT before” are 0.48 and 0.73 for the answer ‘no’ and ‘yes’, respectively (p < 0.0001); for the survey question “Has a healthcare provider ever suggested you do an FOBT” are 0.58, 0.68 and 0.62 for the answer ‘no’, ‘yes’ and unsure, respectively (p < 0.0001 for yes and NS for unsure).
