The experiment was based on understanding  patients with colorectal cancer and caregivers view care quality and to assess factors that may influence concordance. Agreement was assessed with difference scores, concordance with Gwet second-order agreement statistics (AC2), and variation in agreement with stratified analyses. We examined whether the care experiences of patients and caregivers were associated with top-box (most-positive) ratings and examined variations in concordance on the basis of the presence of a top-box score.

Four hundred seventeen patient-caregiver dyads completed the surveys. Quality-of-care ratings were positively skewed, with most dyads indicating top-box ratings. Patient and caregiver care experiences were highly associated with top-box ratings.stratified analyses of patient and caregiver characteristics did not identify any patterns that consistently affected concordance. The concordance statistic significantly decreased for all three outcomes (P < .001), however, when the patient or caregiver assessed quality as anything other than top box.

At last we came to the conclusion that the caregiver and patients report did not vary on these factors. Therefore we think there is a need of detailed analysis over this matter to make things more clearer. The varying factors with caregiver dint made any difference in the final report.
