California Community Burden of Disease and Cost Engine (CCB):
An emerging toolset for epidemiologic analysis and scientific insight, exploring the intersection between health disparities and place
An emerging toolset for epidemiologic analysis and scientific insight, exploring the intersection between health disparities and place
The California Community Burden of Disease and Cost Engine (CCB) is a tool to explore data on burden of disease in multiple levels of geographic granularity in order to answer and generate questions, both simple and complex, about the intersection between health disparities and place.
This tool is designed for use by CDPH programs, local health departments, and community partners for epidemiologic analysis and to provide systematic scientific insight to inform public health planning, evaluation and action.
The CCB currently displays over 15 years of California condition-specific mortality burden data, using a range of measures, displayed at the statewide, county, community, and census tract levels, with interactive rankings, charts, maps and trend visualizations. The list of conditions is based on the Global Burden of Disease system, modified for local public health priorities. The CCB also includes a limited set of social determinants data and describes their correlations with death outcomes, as a pilot for more robust functionality in this area.
The Community Burden of Disease System
- The CCB is the California State implementation piloting the Community Burden of Disease System. The code and system are written and structured to be usable by states and counties throughout the United States-with any state or county using their own structured input file of events (e.g. deaths), and the Community Burden of Disease system supplying underlying population data, social determinants of health data, and all the processing, calculations, and tools to generate a range of interactive displays of multiple rate and count measures.
The CCB is a work in progress
The CCB is intended to be an evolving tool-set developing new content and functionality in response to the needs of public health practitioners. Examples of upcoming development enhancements:
- Cost (charges) data based on hospital discharge
- Life expectancy estimates at the census tract and community levels
- Incorporation of 'multiple cause of death' and 'out of state' death data files
- Expanded range and analysis of social determinants data
- Additional displays of statistical significance
- Enhanced user interface
- Automated report generation
California Department of Public Health CDPH
- Office of Strategic Development and External Relations (Fusion Center) - The CCB is one of the ways the Fusion Center explores the lens of place and its impact on health disparities. The CCB is an initiative of the Fusion Center implemented with participation from a crosscutting technical team, of representatives from multiple CDPH programs.
- This platform is also a pilot component of the CDPH Ecosystem of Data Sharing, leveraging a rich multi-level data set/system for modeling and predictive analytics and demonstrating automated and integrated data processing, analytics, and visualizations. The project employs nimble modular development, with the goal to share tools/resources with outside partners (counties and other states).
Note regarding data suppression
- A number of steps have been taken to address data security issue, including 1) aggregation of year into 5-year groups for data displayed at the community and census tract level, 2) showing less granular cause of death data at more granular geographic levels, 3) suppressing all measures for “strata” or “cells” where the corresponding number of deaths is <11, 4) for gender and race/ethnicity stratified data, if one “cell” within a strata is suppressed per #3, at least one complementary “cell” is suppressed to avoid arithmetic backcalcuation of the suppressed cell, and 5) excluding disaggregated data by sex for neonatal conditions. These procedures assure compliance with the California Health and Human Services Agency Data De-Identification Guidelines (DDG).
Note regarding YEAR or Year Group
- At the County and State levels of geography, YEAR is the individual year of death, with current data from 2001 to 2019. At the Community and Census Tract levels of geography, all data are displayed for the years 2015 to 2019 combined. These years are combined for statistical stability, so that for these more granular levels of geography, the displayed data are still meaningful, and not just the result of random fluctuations.
Note regarding “Race/Ethnicity” for death data:
Race/Ethnicity is shown in the CCB as one combined variable, with mutually exclusive values, in hierarchical order of:
- If a person is listed as “Latino” or “Hispanic” in the original data source they are shown in the CCB as “Latino” regardless of any other designation of race.
For all other persons, if they are listed in the original data source with more than one racial group, they are shown in the CCB as “Multi-race”.
- For example, if they are listed in the original data source as “Black” and as “Asian” they will be shown in the CCB as “Multi-race”.
- If they are listed in the original data source with more than one sub-racial/geographic group within one racial group, they will be shown in the CCB in the racial group, not as “Multi-race”. For example, a person listed in the original data source as Japanese and as Chinese would be shown in the CCB as “Asian”, not “Multi-race”.
- If a person is listed as “Other” race AND as one other single race, they will be shown in the CCB as that single race group, not as “multi-race”.
All other persons (i.e. not Latino and not multi-race) will be shown in the CCB in a single-race.
The following labeling is used for these race/ethnic groups:
|American Indian or Alaska Native||AI/AN|
|Native Hawaiian and other Pacific Islander||NH/PI|
Note regarding “Race/Ethnicity” for hospitalization and emergency department data:
- Coding and labeling of race/ethnicity for hospitalization and emergency department data largely follows the same approach as for death data described above.
- However, prior to 2019 the “Native Hawaiian and other Pacific Islander” and “Multi-Race” categories were not included in those data–presumably such persons would have been included in the “Asian” or “Other” categories as appropriate.
Communities: Throughout the CCB, communities are defined by Medical Service Study Areas (MSSAs), a unique California geographic designation based on aggregation of census tracts, constructed by the California Office of Statewide Health Planning and Development (OSHPD) with each decennial census CHHS/OSHPD/MSSA. MSSAs provide the CCB with a good surrogate for “communities” because:
- there are 542 MSSAs for the 2010 census, providing much more geographic granularity than the 58 California counties and much greater numerical/statistical stability than the 8000+ California 2010 census tracts,
- in general, they are aligned with “communities” in the important sense of geographic, cultural, and sociodemographic similarities (although this is generally more true for urban than rural MSSAs, because of the larger size of MSSAs in rural areas),
- the names associated with each MSSA have some resonance in many cases with local ideas of “community.”
- Although not yet implemented in a fully automated fashion, users can work with the CCB project team to create their own customized communities (based on designated census tracts) for incorporation into the CCB.
Social Determinants of Health: The conditions in which people are born, grow, live, work, and age, including the health system. These circumstances are shaped by the distribution of money, power and resources at global, national and local levels.
Data and other Key Inputs:
From the California Integrated Vital Records System (CalIVRS), based on death certificates/reports processed to the California Department of Public Health, Center for Health Statistics and Informatics (CHSI).
- Files used: “Death Static Master Files (DSMF)” for 2000 to 2004 and “California Comprehensive Death Files (CCDF)” for 2005 to 2019.
Because CCDF Files were used for 2005-2019, deaths of California residents that occurred and were recorded OUTSIDE of California those years have NOT yet been incorporated into any of the CCB working data, visualizations or tables.
A death record was considered to be of a California resident based on field “71, Residence State/Province” for the most recent data and on field “46 State of Residence” for 2001-2004 data. A tiny fraction of these records geocoded to locations outside of California, and others had anomalies suggesting the possibility that the residence was not in California. However, the number of such anomalies is relatively minuscule, such that they are extraordinarily unlikely to have any impact on observed patterns and trends.
County was based on field “62, Decedent's County of Residence Based on City/State (NCHS Code)” for 2011-2019 data and on field “35, Place of Decedent's Residence” for 2001-2004 data except when modified as noted in “Census Tract Data Issues” below.
California death data are geocoded using the CDPH geocoding service, which uses StreetMap Premium for ArcGIS. We have not determined if there is a confidence score or match score below which the census tract for an address is not provided. For the years 2011-2019 where the CCB uses these data to determine census tract and (and therefore communities), a high percentage of records geocoded to a valid census tract (96.4% to 97.2%). The remaining records contained invalid addresses and/or other anomalies. While this overall rate of geocoding is high, there is substantial variation in the geocoding percent between counties, and some counties (particularly some rural counties) have geocoding rates as much as half of those noted above
Note: As with almost all public health and administrative data used to assess population patterns and trends in morbidity and mortality, vital statics death data are not error free. “Data quality issues inherent in death certificate data most often stem from errors related to the fact that the responsibility for providing complete and accurate information lies with the informant and certifier. This may impact classification of deaths and consequently under- or over-estimations of mortality.”
Social Determinants of Health (SDOH)
- The CCB currently contains a small, exploratory set of SDOH variables extracted from the California Healthy Places Index (HPI) (publicly available files at HPI). The CCB short term road-map includes a plan to extract SDOH data directly from US Census / American Community Survey API (URL) using the R tidycensus package. Of note, related publicly available data for all census tracts in the United States can be downloaded from the CDC/ASTDR Social Vulnerability Index (SVI) project at CDC/ASTDR/SVI.
- For counties, all population denominator data are from the California Department Department of Finance (DOF). 2000-2009 data are California and Counties Population by Age, Race/Hispanics, and Gender: 2000–2010 estimates and 2010-2020 data are Complete State and County Projections (Table P-3).
For census tracts (and therefore communities) population denominator data are based on the American Community Survey 5-year extracts (tables B01001_001E, B01001_002E, and B01001_026E) using the most recent 5-year period available corresponding to the 5-year tract/community data being analyzed in the CCB (e.g. 2015-2019 death data uses the 2019 ACS data, which covers 2015-2019). Community population data are generated by aggregating these census data up to the community level.
- Because of the ACS data release schedule, where data for the “current year” are not always available, population data for the “prior year” will be used as population data for the “current year” until true “current year” data are available
- ACS data are extracted directly from the Census/ACS API (Application Program Interface) using the R tidycensus package.
- Boundary (or “shape”) files for the CCB were generated using the tracts() function of the R tigris package, modified to be of smaller file size using the ms_simplify() function of R rmapshaper package, and with removal of islands off the west coast of some counties using a custom island removal function.
- Maps do not currently use any explicit projection, but easily could, and probably should, based on user input.
- In the current version of the CCB project, only the single underlying cause of death ICD-10 code is used. A future release of the CCB will incorporate “multiple cause of death” codes for some conditions.
We based the hierarchical list of about 70 disease/injury conditions used in the CCB on a variant of the World Health Organization (WHO) global burden of disease condition list, modified to enhance the usefulness and applicability for U.S. public health priorities and programs. The hierarchy has three levels. The “Top Level” includes “Communicable, maternal, perinatal and nutritional conditions”, “Cancer/Malignant neoplasms”, “Cardiovascular diseases”, “Other Chronic Conditions”, and “Injuries” as well as all causes combined. For data displayed at the census tract level, only this level of the hierarchy is included due to sample size and statistical reliability limitations. The next “Public Health” level splits each of these top levels into around 50 subcategories, and this is the default level for data/maps displayed at the community level. The final detailed level breaks a few of these Public Health level conditions down further, for the total of about 70 categories. All the levels are shown for data/maps displayed at the county level.
- County: Top Level, Public Health Level, Detail Level
- Community: Top Level, Public Health Level
- Census Tract: Top Level
Categorization of deaths was extracted from death certificates based on the International Classification of Diseases version 10 (ICD-10). The primary basis for the ICD10-to-condition mapping was the WHO Annex Table A from “WHO methods and data sources for global burden of disease estimates 2000-2015, January 2017”. We did not use a similar, more recent and more detailed, system developed by the Institute for Health Metrics and Evaluation (IHME) at the University of Washington (recent relevant publications include The State of US Health, 1990-2016 Burden of Diseases, Injuries, and Risk Factors Among US States, JAMA 2018 and US County-Level Trends in Mortality Rates for Major Causes of Death, 1980-2014, JAMA 2016) in this version of the CCB because that system resulted in 721,783 (19.2%) of California deaths from 2000 to 2015 being mapped to “garbage codes”, for which more sophisticated methods would need to be employed. The possibility of redistributing these “garbage codes” to valid categories at the census tract level and otherwise using the IHME system is being explored and may be implemented in future versions of the CCB. However, to enhance our use of the WHO system we compared the mapping of 3,758,856 deaths based on the WHO and IHME systems and changed the WHO mapping of ICD codes for several categories wherein the IHME classification was considered more appropriate (e.g., specific cancer sites rather than “other malignant neoplasms.”). All of these modifications are carefully described in a key resources tool for the CCB, available here on our GitHub site. In addition, because our focus was on the “Public health” list of conditions, we remapped a number of ICD-10 codes from the WHO mapping to our own CCB system. All of these modifications are documented in a “key resources” tab for the CCB available noted above. The latest IHME/GBD results and methods can be found here.
For some conditions for some charts an abbreviated label is used. For most this is unambiguous, but for a couple additional detail may be useful:
- “Alzheimer's disease” = “Alzheimer disease and other dementias”
- “Lung Cancer” = “Trachea, bronchus and lung cancers”“
NOTE: In order make drug- and poisoning-related conditions in the CCB as meaningful as possible for public health, and to maintain the condition list as mutually exclusive and exhaustive, we have modified these conditions from WHO and IHME standards based on consensus with colleagues and on "Consensus Recommendations for National and State Poisoning Surveillance – ISW7 2012”.
- The “Drug overdose (poisoning/substance use disorders)” condition includes “accidental poisonings by drugs” codes (X40-X44) and “substance use disorder codes” (F11-F16, F18, F19), but not alcohol use disorder (F10) which is included in the separate detailed level “Alcohol use disorders” condition. This conditions also includes “newborn (suspected to be) affected by maternal use of drugs of addiction” (P044).
“Drug overdose (poisoning/substance use disorders)” does not include:
- “Intentional self-poisoning by drugs” (X60-X64), which is included in the “Suicide” condition
- “Assault by drug poisoning” (X85), which is included in the “Homicide” condition
- “Drug poisoning of undermined intent” (Y10-Y16), which is included in the “Injuries of unknown intent” condition
The separate “Poisonings (non-drug)” conditions includes poisoning with non-drug-related substances (X46-X49).
Census Tract Data Issues
- Of the 8041 California census tracts in the 2010 Census “Tiger” files, five have zero land area (only water), and (not surprisingly…) have zero population and zero deaths. These tracts are excluded from CCB data processing and display.
- Of the remaining 8036 tracts, 12 have zero population and zero deaths. By definition, these tracts are excluded from all analyses, and will show values of “0” or missing for all measures in all maps. These tracts are wholly comprised of industrial facilities, airports, or parks.
Census tract issues to be addressed:
- Census tracts (and communities) where greater than 50 percent of the population live in congregant living quarters will be noted in the future with an “*” on relevant maps and charts in an upcoming CCB release. For some comparisons (e.g. of rates) these tracts could be removed from the larger geographies in which they are contained.
- During detailed review of multiple data sources, we observed a number of instances where stated county of residence was not consistent with the census tract to which that death was geocoded. In these instances we will consider recoding the county based on the address and subsequent geocode.
Formulas and Measures
Years of Life Lost (YLL)
- Two methods are available for calculating YLL.
In the current implementation of the CCB, we use the first method below. For local health departments, or others using their own implementation of the CCB, both method are coded, and either one can be selected (in the “E1.make_death_datasets_for_app.R” file)
- The first method is simpler, and is based on summing for all deaths, the number of years prior to age 75 that each death occurs, with 0 YLL used for deaths occurring at ages >= 75. This method has the advantage of (1) emphasizing more strongly deaths that occur at younger ages and (2) being simpler to explain and understand. It has the disadvantage of not being consistent with the methods of the Institute for Health Metrics and Evaluation, prohibiting direct comparisons with their results.\
- The second method uses the current approach of the Global Burden of Disease Study. With this method the YLL for each death is based on the age at death, and the additional number of years a person living in an optimal setting could be expected to live (page 30, here). For example, someone dying at birth would be associated with 91.94 YLL, someone dying at 25 associated with 67.08 years, and someone dying at 98 with 3.70 years. Beyond the published data, when we use this method, we associate 1.0 YLL for anyone dying above age 105.
All rates are expressed per 100,000 people based on the following calculations:
- 100,000*(number (e.g. deaths, potential years of life lost) / midyear population)
Confidence intervals for crude rates are based on the pois.approx() function of the R epitools package.
Age adjusted rates
- Age-adjusted rates are based on the “direct” method, using standard definitions and procedures. Great descriptions and the motivations for these methods can be found here, from the New Jersey Department of Health, and here, from CDC.
- The Standard Population used is based on the 2000 projected U.S. population published by CDC/NCHS in January 2001–specifically, Table 2, Distribution #1 was used, but with age groups <1 and 1-4 combined. These ten age-groupings and corresponding standard population numbers can be found here.
- The age-adjustment calculation, and generation of confidence intervals, was conducted using the “ageAdjust.Direct()” function of the R epitools package.
- Because a very small number of census tracts with otherwise useful data had zero population in one or more age strata (often the youngest or oldest strata, for just one sex), the above-mentioned function was modified such that rates in such strata were assigned to (reasonably enough) be 0 (rather than undefined/infinity), allowing an adjusted rate to be calculated.
- Life tables for tracts, communities, counties and states are generated from age specific mortality rates, which are the quotient of deaths during a calendar year to the person-years of exposure to mortality hazard, approximated by the population of the same age range at the midpoint of the year (July 1). Age structured population data for communities are estimated using aggregation of census tract level data from the American Community Survey, 5-year sample (table B01001; multiple years). County and state age population by age are estimated by the Demographic Research Unit, CA Department of Finance. Deaths by age are based on 100% tabulations obtained from the CA Department of Public Health.
Life tables were estimated for communities (MSSAs) in counties where at least 95% of deaths could be accurately geocoded to the tract level. Mortality and exposure data were combined on the basis of 1-, 3-, or 5-year intervals. Life tables with fewer than 700 deaths or 10,000 person-years of exposure were censored. Intra-age mortality (~n~a~x~) was calculated for ages below 5 using values from a standard population (California life tables from the US Mortality Database). Confidence intervals were calculated from standard errors for age specific probabilities of death using Chiang's method (Chiang 1984) with adjustments to the final age group (Eayres 2004).

- Hospitalization data are based on 2016 nonpublic Patient Discharge Data received from the California Office of Statewide Health Planning and Development (OSHPD). OSHPD provides such files from inpatient data they collect from California-licensed hospitals. The data set consists of a record for each inpatient discharged from a California-licensed hospital. Licensed hospitals include general acute care, acute psychiatric, chemical dependency recovery, and psychiatric health facilities. Data are not collected from Veteran's Administration, Military or other Federal Hospitals or from Tribal Hospitals.
- Detailed information for the current OSHPD Patient Discharge Data and data system can be found here and a link to the 2016-specific data can be found here.
For each hospitalization one total charge is listed, reflecting the charges associated with the primary condition as well as any other charge associated with the hospitalization.
- Total charge is all charges for services rendered during the length of stay for patient care at the facility, based on the hospital's full established rates. Charges include, but are not limited to daily hospital services, ancillary services, and patient care services.
- Hospital-based physician fees are excluded, as are items like take-home drugs, television, follow-up home health visits, ambulance services, etc.
- Hospitals report 'Total Charges' to OSHPD for the last 365 days of stay. However, starting in 2015, in the files released by OSHPD 'Total Charges' are adjusted to reflect the entire length of stay.\
- A hospitalization can have multiple discharges if the patient moves between type of care (e.g. psychiatric to acute would be two discharges during the same overall hospital stay) and each discharge has a related total charge.
- Charges of $1 specify 'no charge' or charity care.
The noted charges are based on hospitals' administrative systems and do not indicate actual costs/payments for those charges.\
Nevertheless, because the CCB describes summary data, the charts and tables shown provide valuable information regarding the patterns of the monetary burden of disease/conditions in California from the hospitalization perspective.
For some hospitalizations, no charges are reported to OSHPD, and for some hospitalizations implausibly high charges (likely errors) have been excluded, so total charges may be slight underestimates from this perspective. 'Average' charges in these charts are based on the median rather than the mean, so are largely not impacted by these issues.
- For each hospitalization, one condition is established and coded as the chief cause of the admission, and is noted as the Principal or Primary diagnosis. Up to 24 other conditions that coexist at the time of admission, that develop subsequently during the hospital stay, or that affect the treatment received are also included and noted as Other or Secondary diagnoses.
- Coding for these Principal and Other diagnoses are based on the ICD10-CM system (from October 1, 2015 forward; prior to this time ICD9-CM was used), along with standardized guidance.\
- The codes entered by the hospitals are subject to multiple sources of variation or potential error (e.g. selective use of codes for billing purposes). Nevertheless, since the data are used in the CCB in summary form, the overall patterns displayed are likely to be meaningful and informative.
Grouping of ICD-10-CM Codes
ICD10-CM codes are highly detailed and specific, with more than 93,000 codes. There are many ways these codes can be grouped or summarized into meaningful categories. We continue to explore which grouping system(s) are most useful for purposes of the CCB, and would welcome your input. At this time, settings are available to toggle between these options. Four possible systems include:
- The Global Burden of Disease system (GBD) system (coded by the CCB team), groups the hospitalization ICD-10-CM codes into conditions based on, generally, the Global Burden of Disease system, as described above for death data, and includes 'high volume' conditions and some other conditions of clear programmatic public health interest in California. At the moment, this system is not exhaustive, and includes only a sample of conditions of interest.
- The Major Diagnostic Categories (MDCs) system (included in the OSHPD data set), groups principal diagnoses into 25 mutually exclusive diagnosis groupings. The diagnoses in each MDC correspond to a single organ system or etiology and, in general, are associated with a particular medical specialty. The system was established and is maintained by the U.S. Department of Health and Human Services (DHHS) Centers for Medicare and Medicaid Services (CMS).
- The Medicare Severity Diagnosis Related Group (MS-DRG) system (included in the OSHPD data set), categorizes patients based on clinical coherence and expected resource intensity, with respect to diagnoses, treatment and length of hospital stay. The assignment of an MS-DRG is based on: the principal diagnosis and any secondary diagnoses, surgical procedures performed, comorbidities and complications, patient's age and sex, and discharge status. The system was established and is revised annually by CMS. See CCR Section 97212.
- The Clinical Classifications Software (CCS) system (included in the OSHPD data set) is a tool provided by the Agency for Research and Quality Healthcare Cost and Utilization Project. CCS aggregates the ICD codes into a manageable number (285) of clinically meaningful categories to make it easier to quickly understand diagnosis patterns. The system is evolving, with the current system organized across 21 body systems, which generally follow the structure of the ICD-10-CM diagnosis chapters.

A URL can be constructed and shared that links to a specific “tab” on the CCB with some specific parameters selected.
For example the following URL links to the cause of death rankings in Fresno County in 2018:
Constructing the URLs is based on the following structure and values:
Four query parameters
- Table below shows possible value inputs
- Full county name
- Inputs cause codes, not cause names.
- Cause codes can be found in the 'Cause of Death' dropdown, located on most tabs (e.g. Trends -> Sex Trends)
- The cause code is the letter(s) and numbers before the cause name
- Use just the letter(s) and number; no periods or spaces
- Four digit number
General query pattern to add at the end of the url:
Specific CCB query pattern:
- Not all parameters are relevant for all tabs
- Not all parameters for a given tab need to be specified. If no parameter is given, a default value will be used.
Example 1 - Linking to Sex Trend Tab, Alameda County, Ischemic Heart Disease
Example 2 - Linking to Race Trend Tab
