Low Awareness of and
Referral to National Cancer
There are currently more than 11 million
cancer survivors in the United States ( 1 ).
With improvements in cancer screening
technology and treatment, this number is
likely to increase. The information needs
of cancer patients and survivors could strain
an already burdened health-care system,
underscoring the need for reliable cancer
information from credible sources ( 2 – 4 ).
Although many quality cancer informa-
tion resources are available, recent data ( 5 )
indicate that health-care professionals are the
most trusted source for health information,
followed by US government health agencies
that produce and scientifi cally vet materials
for patients and health-care professionals,
such as the National Institutes of Health
(NIH) and the Centers for Disease Control
and Prevention (CDC). The National Cancer
Institute’s Web site ( www . cancer . gov ) and
the Cancer Information Service (1-800-4-
CANCER) serve as NIH’s primary cancer
information resources. The CDC Web site
( www . cdc . gov ) also serves as a cancer infor-
To assess the awareness of and referral
to national cancer information resources
among primary care physicians, we ana-
lyzed data from the National Survey of
Primary Care Physicians ’ Recommendations
and Practice for Breast, Cervical, Colorectal,
and Lung Cancer Screening. The survey
was fi elded in 2006 and 2007 as a mailed
questionnaire. The sample was drawn from
the American Medical Association Physician
Masterfi le by using a systematic sample
design that was stratifi ed by medical spe-
cialty type. Eligible respondents were non-
federal offi ce-based family physicians,
general practitioners, general internists,
and obstetricians and gynecologists aged
75 years or younger. A total of 1212 physi-
cians completed the survey for a 73.4%
cooperation rate and a 67.5% response rate.
Details about sampling and survey method-
ology are published elsewhere ( 6 ).
Respondents were asked “Are you aware
of, and have you ever referred a patient to,
any of the following services for cancer in-
formation: 1-800-4-CANCER; www . cancer
. gov ; and www.cdc.gov?” Response options
were “aware and referred,” “aware of it,
never referred,” and “not aware of it.”
Awareness and referral were assessed by phy-
sician and practice characteristics.
(Research Triangle Institute, Research
Triangle Park, NC), was used to calculate
weighted percentages and 95% confi dence
intervals (CIs). Cross tabulations with
two-sided ? 2 and t tests and a multinomial
regression analysis were conducted to dis-
cern physician and practice characteristics
associated with awareness and referral.
Awareness and referral to national in-
formation resources was low: 6.2% of phy-
sicians reported awareness and referral to
1-800-4CANCER, 14.0% reported aware-
ness and referral to www . cancer . gov , and
23.1% reported awareness and referral to
www . cdc . gov ( Table 1 ). Greater awareness
of and referral to at least one of these re-
sources was associated with more time
spent teaching ( P = .046 [ t test]) and con-
ducting administrative duties ( P = .046
[ t test]). Lower awareness and referral was
observed among physicians who were in
private practice ( P = .001 [ ? 2 test]), had
larger patient loads ( P = .015 [ ? 2 test]), or
had a higher percentage of uninsured
patients ( P = .015 [ ? 2 test]). A multinomial
logistic regression analysis revealed that
compared with physicians in university

At least one resource
settings, those in private practice were less
likely to be aware of and refer to national
cancer information resources (odds ratio =
0.50, 95% CI = 0.34 to 0.74) and less likely
to report awareness and no referral (odds
ratio = 0.49, 95% CI = 0.32 to 0.74).
Low levels of awareness of and referral to
national cancer information resources were
observed across physician and practice char-
acteristics. Efforts to raise awareness and use
of these resources could improve informa-
tional support to health-care providers, can-
cer patients, and survivors.
