Using (and Augmenting) Georgia Cancer Registry
Data to Understand and Improve Survivor Outcomes
2Who Is a Cancer Survivor?(Critical for
Defining the Scope and Breadth of Data Required
for Analysis)
- An individual is considered a cancer survivor
from the time of diagnosis, through the balance
of his/her life. Family members, friends, and
caregivers are impacted.and included in this
definition. - (Office of Cancer Survivorship, National
Cancer Institute http//dccps.nci.nih.gov/ocs/) - The term cancer survivors refers to those people
who have been diagnosed with cancer and the
people in their lives who are affected by the
diagnosis, including family members, friends, and
caregivers. - (from A National Action Plan for Cancer
Survivorship, issued jointly by the Centers for
Disease Control and Prevention and the Lance
Armstrong Foundation http//www.cdc.gov/cancer)
3What Are the Outcomes of Interest
- Quantity of life (survival)
- Quality of life
- - Symptom bother
- - Functional status (e.g., carrying out
normal activities of daily living) - - Health-related quality of life (HRQOL)
an integrated assessment of the impact of
health-related events on the individuals overall
level of self-assessed well-being, often taking
into account physical, social, and psychological
functioning - Economic status of the cancer survivor and
his/her family
4 Improving the Outcomes of Cancer Care
National Cancer Institute Perspective
Identifying Interventions that Improve Outcomes
Strengthening Science Base for Quality of Care
Measuring Outcomes that Matter
Impacting the Delivery of Care
Monitoring Progress and Identifying New Targets
5Major Survivorship Research and Policy Issues
Requiring Ongoing Empirical Study (as reflected,
for example, in the NCI research agenda)
- Chronic and late effects of cancer and its
treatment - Interventions to reduce or halt these effects
- Health lifestyle and behaviors (to reduce the
risk of cancer recurrence and improve overall
quality of life and survival) - Benefit finding and posttraumatic growth
following the diagnosis and treatment of cancer - Family impacts
- Health disparities
6What Kinds of Data Are Required to Study Such
Survivorship Issues in Georgia?
- Specific, targeted questions can be addressed by
specific data sources (e.g., expected survival
can be estimated from high-quality cancer
registries HRQOL can be estimated at a slice in
time by well-executed survey of individuals
diagnosed with cancer) - But to acquire the capability to address a full
range of cancer survivorship issues, Georgia
needs a comprehensive cancer data system that
capitalizes on a range of current information
sources and develops additional ones.
7Components of a Comprehensive State-Based Cancer
Data System for Survivorship Analysis
- Strong cancer registry system -- and the Georgia
Comprehensive Cancer Registry (GCCR) is strong
indeed - Access to medical records/charts of cancer
survivors, during primary treatment and beyond
the more electronic the data, the better - Access to insurance claims data (Medicare,
Medicaid, private indemnity plans, managed care) - Information on symptoms, HRQOL, economic
consequences of cancer from the survivors own
perspective - Link it all together to develop, for each
individual diagnosed with cancer, a rich
longitudinal picture of what it is like to live
with, through, and beyond cancer -
8Components of a Comprehensive State-Based Cancer
Data System for Survivorship Analysis
- Such a population-based cancer data system has
been recommended by the Institute of Medicine
(Enhancing Data Systems to Improve the Quality of
Cancer Care, 2000 and From Cancer Patient to
Cancer Survivor Lost in Transition, 2006). - Likewise, the forthcoming Georgia Comprehensive
Cancer Control Plan has, as one of its Data
Metrics Goals, to expand and enhance data
collection from existing and new sources. - But can we get there from here? Do we have
examples of how cancer registry data can be
augmented to study the quality and outcomes of
care over time? - (Yes we do!)
9 Example 1, the CDC-supported study being
conducted by Emory University investigators on...
- Determinants of Patient Dropout from Cancer
Treatment and Follow-up
10Background Motivation
- Numerous patterns-of-care studies report that
cancer patients frequently do not receive
guideline-concordant care (Institute of Medicine,
1999). - Yet, little is known about patients not
completing prescribed therapy, the factors that
predict patient dropout, and even whether
currently available data systems are adequate to
support such analyses.
11Primary Study Goals
- (1) Examine frequency of failure to complete
prescribed treatment for breast, colorectal,
lung, and prostate cancers within the 1st year of
diagnosis among residents of Southwest Georgia
a 33-county region of the state.
Region of SW GA Cancer Coalition
12Primary Study Goals
- (2) Investigate tumor-specific and
patient-related, provider-related, and health
system-related factors associated with premature
treatment discontinuation in this largely rural
population. - (3) Determine the types of data sources and
information systems required to achieve goals (1)
and (2) in a population-based cancer treatment
environment. - Additional Study Goals
- (4) Identify interventions to reduce dropout
- (5) Propose strategies to disseminate findings
- (6) Recommend whether longer-term follow-on
study is warranted
13Discussion and Conclusions I
- In this rural population, 85 of breast cancer
patients and 67 of colorectal cancer patients
overall completed adjuvant chemotherapy - Those cases who stopped prior to finishing
treatment were much more likely to do so for
toxicity and other clinical reasons than for
refusal/lack of support - Married CRC patients were significantly more
likely to complete treatment than patients who
were single, divorced or separated - Among non-married breast cancer patients, older
women and whites were more likely to discontinue
chemotherapy for reasons other than completion
14Discussion and Conclusions II
- In all analyses undertaken, white/non-white
differences in chemotherapy receipt and treatment
completion were either non-significant or else
suggested higher completion rates for non-whites - Future analyses will focus on the relationship
between treatment plan and compliance, using
qualitative research to investigate provider
decision making
15Example 2funded by CDCs National Program of
Cancer Registries (NPCR)
- Breast and Prostate Cancer
- Data Quality and Patterns of
- Care Study
16Background and Motivation
- In two influential reports, National Cancer
Policy Board of the IOM (1999, 2000) emphasized
both inadequacy of our present understanding of
cancer care quality and important role of NPCR in
monitoring and improving quality. - The two most common cancers in Georgia are breast
and prostate (gt5,000 cases each in 2004). - Georgia Comprehensive Cancer Registry is one of
the nations best and can become still better
for patterns-of-care and quality-of-care
assessment.
17Primary Study Goals
- Describe patterns of care for female breast and
prostate cancer among Georgia residents, based on
a stratified random sample of 2,000 cases of BC
and 2,000 cases of PC diagnosed in 2004 - Examine the degree to which cancer care is
guideline concordant a frequently used
approach to quality-of-care assessment - Investigate factors that may influence patterns
of care and guideline concordance - -- tumor-related
- -- patient-related (including
race/ethnic, socio- - economic, and geographic
variables) - -- provider-related
- -- health system-related
- Assess and improve the quality of the data on
cancer care and outcomes
18Examples of Specific Hypotheses (cutting across
both breast and prostate cancer)
- Patients at higher socio-economic status more
likely to receive guideline-concordant care as
defined by the National Comprehensive Cancer
Network (NCCN) guidelines - Younger patients more likely to receive guideline
concordant pre-treatment evaluation and care - Patients comorbidity status will significantly
influence choice of care, with strength of the
effect varying by age and stage of disease - Non-Hispanic whites more likely to receive
guideline-concordant care than Hispanics and
non-white race - Patients seeking pre-treatment evaluation at
high-volume facilities more likely to receive
guideline concordant care
19Organization of the Study
- A 7-state consortium formed by CDC in Oct 2005
following competitive selection process (RFA
grant mechanism) GA, CA, LA, KY, MN, NC, and
WI. - Critically important element of study in Georgia
Collaborative relationship between GCCR, GA
cancer registrars, and Emory investigators. -
20 Example 3 Prostate Cancer Outcomes Study
(data from multiple states, NCI-supported)
- OBJECTIVES
- Describe diagnosis and treatment patterns for
prostate - cancer among large (N 3,500) diverse group
of men - treated in community settings and followed
periodically - Assess health-related quality of life among
prostate cancer survivors at 5 time points over
5-year period - Focus on complications associated with prostate
cancer urinary, bowel, sexual - Overcome limitations of previous studies,
including - -- Patients from single institutions
- -- Quality of life evaluated by doctors, not
patients - -- Cross-sectional, not longitudinal
-
-
21Some PCOS Findings
- The prevalence of urinary, bowel, and sexual
impairments is substantially higher than some
estimates from referral centers and leading
academic institutions. - As part of treatment planning, clinicians should
consider mens baseline function and age, since
these also predict subsequent outcomes and
recovery after treatment. - PCOS data are increasingly being used as a
treatment decision resource by patients and
physicians in the community setting. - Need for new therapies with lower rates of
complications.
22Example 4
- CanCORS
- Cancer Care Outcomes Research and Surveillance
Consortium A 6-year, 40M, project supported by
NCI and VA to - study the impact of targeted interventions on
patient-centered outcomes - investigate dissemination of state-of-the-art
therapies in the community - examine gaps between best, evidence-based
clinical practice and actual care in community - analyze disparities in quality cancer care
-
23CanCORS Study Design
- Large observational cohort study of newly
identified lung and colorectal cancer patients - -- For lung 5 research teams with N
4,700 - -- For colorectal 6 research teams
with N 5,300 - Socio-economically,geographically, and
race/ethnically diverse samples - Public-private provider mix large HMOs,
fee-for-service, VA medical centers
24CanCORS Study Design
- Rapid case ascertainment lt 3 months after
diagnosis - Follow-up patients 12 months after diagnosis
- For each patient, creates a longitudinal profile
of cancer care by utilization multiple data
sources - Investigate structure - process - outcome links
at the patient, provider, and organizational
level
25CanCORS Specific Aims
- 1) To determine how the characteristics
beliefs of cancer patients and providers and the
characteristics of health-care organizations
influence treatments and outcomes, - spanning continuum of cancer care from diagnosis
to recovery or death - 2) To evaluate effects of select processes of
care on patients survival, health-related
quality of life, and satisfaction with care
26Some CanCORS High-Priority Questions
- How and why do processes and outcomes of care
vary by patient age, race, ethnicity, SES? - Why do high-volume hospitals tend to have lower
surgical mortality rates? - How do patients and physicians go about making
treatment decisions for metastatic cancer? - Are symptoms (especially pain and depression)
treated effectively?
27But these and other specific studies do not
produce, nor benefit from, a strong, enduring,
population-based cancer care data system.
- How do we build such a system in Georgia to
understand and improve survivor outcomes?
28What are the Options?
- (1) Rely primarily on registry data
- - Such data crucial foundation for
many survivorship studies - - Sufficient to study impact of
cancer on quantity of life (mortality survival) - - But does not address
quality-of-life and economic consequences of
cancer and its treatment
29What are the Options?
- (2) Link registry data with insurance claims data
- -- the linkage of the NCI Surveillance,
Epidemiology, and End Results (SEER) data with
Medicare claims has resulted in a data base
(SEER-Medicare) supporting numerous studies of
patterns of care, quality of care, and economic
outcomes for cancer survivors across the U.S. - -- And, starting with the observation
period 1999-2002, we now have Georgia-Medicare - -- Next, we need Georgia-Medicaid and
also the linkage of private insurance claims data
to Georgia cancer registry data - -- Aim create a (near) population-represent
ative data base linking (most) every Georgia
cancer registry record with the individuals
insurance claims files - At least one significant problem the
uninsured!
30What are the Options?
- (3) Extend the follow-up period of existing
patterns-of-care/quality-of-care (POC/QOC)
studies - For example, continue to follow the
survivors now enrolled in the Breast and Prostate
Cancer POC/QOC study and the SW Georgia cancer
care drop-out study - (4) Launch new POC/QOC studies over time, in a
strategic fashion to (a) encompass a broad array
of tumor types and (b) include patient-reported
outcomes such as symptom bother, HRQOL, and
economic consequences
31What are the Options?
- (5) To augment POC/QOC studies that do not
collect patient-reported outcomes, expand and
intensify population-based surveys that capture
symptom bother, HRQOL, economic outcomes, and
other data important for interpreting the
experiences of the cancer survivor, caregiver,
and others touched by cancer
32What are the Options?
- (6) Continue to follow patients enrolled in
cancer clinical trials well beyond the end of
the study, and expand the data collected to
include patient-reported outcomes - -- As the Georgia Center for Oncology
Research and Education (GA CORE) works to
increase the number of clinical trials across the
state, this option should receive heightened
attention
33What are the Options?
- (7) Over the long term, seek to establish a new
standard of health care data collection at the
site of care, to include information on the
patients socioeconomic status (e.g., education
level), stage of cancer disease (if relevant),
comorbid conditions, and patient-reported
outcomes including symptom bother, HRQOL, and
economic consequences of disease and treatment. - -- Aim to make such data part of the
patient record that can then be abstracted in
POC/QOC studies, thus reducing need for separate
surveys
34Challenges
- Affordability covering the cost of an expanded
Georgia cancer data system - Sources state govt, federal govt,
funded research, foundations, private industry - Cooperation, Coordination, Collaboration
multiple public and private entities with a
strong interest in the cancer survivor and also
unique perspectives, agendas, and fiscal
administrative constraints - Patient Privacy and Confidentiality the
importance (and the considerable cost) of
obtaining informed consent and ensuring privacy
of medical records
35But we should keep our eyes on the Prize.
- A comprehensive Georgia cancer data system that
enables us to understand and improve healthcare
outcomes for cancer survivors across the state
36- The Opportunity
- and
- The Commitment
