BACKGROUND
Complementary
and alternative medicine (CAM) incorporates treatments used by cancer
survivors in an attempt to improve their quality of life. Although
population studies have identified factors associated with its use, to
the best of the authors knowledge, assessment of why patients use CAM or
the barriers against its use have not been examined to date.
METHODS
The
authors conducted a cross-sectional survey study in the thoracic,
breast, and gastrointestinal medical oncology clinics at an academic
cancer center. Clinical and demographic variables were collected by
self-report and chart abstraction. Attitudes and beliefs were measured
using the validated Attitudes and Beliefs about CAM (ABCAM) instrument.
This instrument divides attitudes and beliefs into 3 domains: expected
benefits, perceived barriers, and subjective norms.
RESULTS
Among
969 participants (response rate, 82.7%) surveyed between June 2010 and
September 2011, patient age ≤65 years, female sex, and college education
were associated with a significantly greater expected benefit from CAM (P<.0001 for all). Nonwhite patients reported more perceived barriers to CAM use compared with white patients (P<.0001), but had a similar degree of expected benefit (P
= .76). In a multivariate logistic regression analysis, all domains of
the ABCAM instrument were found to be significantly associated with CAM
use (P<.01 for all) among patients with cancer. Attitudes
and beliefs regarding CAM explained much more variance in CAM use than
clinical and demographic variables alone.
CONCLUSIONS
Attitudes
and beliefs varied by key clinical and demographic characteristics, and
predicted CAM use. By developing CAM programs based upon attitudes and
beliefs, barriers among underserved patient populations may be removed
and more patient centered care may be provided. Cancer 2015. © 2015 American Cancer Society.
