Outcome Measures

Primary Outcomes (1)

  • Mean differences on EORTC QLQ-INFO25 - Patient-Perceived Cancer-Related Information

    Patient-perceived quality, breadth, and depth of cancer-related information received following an oncology consultation, as measured by the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-INFO25) survey. The EORTC QLQ-INFO25 comprises four multi-item scales and eight single items to assess the level and quality of information received by cancer patients. Scores for all scales and single items range from 0-100. The survey uses a 4-point Likert scale (1 = "not at all' to 4 = "very much") and some yes/no questions. Higher scores represent a greater patient-perceived level of shared decision-making. Mean differences between treatment groups will be reported with 95% confidence intervals, along with Hedges' g effect sizes. A Mann-Whitney U test will be used for sensitivity analysis.

    Up to 2 days

Secondary Outcomes (3)

  • Mean differences on SDM-Q-9 and SDM-Q-Doc - Patient- and Provider-Perceived Shared Decision Making

    Day 21

  • Mean differences on NCCN Distress Thermometer - Patient-Reported Distress

    Up to 21 days

  • Patient-Provider Concordance in Shared Decision Making

    Day 21
