Abstract
Background: Integrative oncology (IO) seeks to bring non-conventional approaches into conventional oncology care in an evidence-based, coordinated manner. Little is known about the effects of such consultations on patient-reported symptoms.
Methods: We reviewed data from patients referred for an IO outpatient consultation between 2009 and 2013, comparing the cohort of patients with at least one follow-up to the cohort with an initial consultation only. Assessments completed at initial and follow-up encounters included: complementary and alternative medicine (CAM) use questionnaire, Measure Yourself Concerns and Wellbeing (MYCaW), Edmonton Symptom Assessment Scale (ESAS; 10 symptoms, scale 0-10, 10 worst), and post-consultation satisfaction. ESAS individual items and global (GDS; score 0-90), physical (PHS, 0-60) and psychological (PSS, 0-20) distress scales were analyzed.
Results: 642 patients out of 2,474 (26%) new patient IO consultations had at least one follow-up encounter (mean 3.2; SD 1.8). Age, place of residence, and higher satisfaction were predictors of follow-up. Statistically significant improvement in symptoms between initial consult and follow-up were observed for depression, anxiety, well-being, and subscales of GDS and PSS (all p's > 0.01). For those with moderate to severe symptoms at their initial consult (ESAS scores ≥ 4), we observed clinical response rates (improvement) of 49-75% for all ESAS symptoms at follow-up.
Conclusions: Patients presenting for IO follow-up had overall mild to moderate symptoms at baseline and stable symptom burden over time. Greatest improvements were observed for psychosocial symptoms, most pronounced for the subset of patients with moderate to severe symptoms at their initial consultation.
