About Carbon Monoxide Data
About the Data
This site provides hospitalization data for the number and rate of CO hospitalizations for New York State. Information is extracted from the Statewide Planning and Research Cooperative System (SPARCS) database. These data include people who required extended care in a hospital because of CO poisoning. The data do not include records for people who visited and were treated in hospital emergency rooms but discharged without being admitted.
Mortality data is provided for the number and rate of CO deaths for New York State. Information is extracted from the Centers for Disease Control and Prevention (CDC)-maintained WONDER (Wide-ranging Online Data for Epidemiologic Research) database -- an easy-to-use, menu-driven system that makes the information resources of the CDC available to public health professionals and the public at large. It provides access to a wide array of public health information. The Multiple Cause of Death data available on WONDER are county-level national mortality and population data spanning the years 1999-2006.

Interpreting Data
Not all cases of CO poisoning are included here. SPARCS hospitalization data only include records of people admitted to the hospital. Therefore, the data presented here represent more severe cases of CO poisoning. SPARCS collects emergency room data in a separate database and these data may be added in the future.
The hospitalization and mortality data represent individual cases of CO poisoning and individual deaths. They do not provide insight into the number of episodes which resulted in individual cases of CO poisoning or CO deaths. Annual variations in the number of people hospitalized for CO poisoning and the number of CO deaths may not reflect an increase in episodes of CO poisoning or mortality, but instead may reflect variations in the number people who were poisoned per episode. NYSDOH staff are discussing potential strategies to evaluate this issue.
Rate
A rate provides information about patterns of carbon monoxide poisoning hospitalizations and mortality over time and by geographic location. Hospitalization rates are calculated by dividing the total number carbon monoxide poisoning hospitalizations by the total population of a particular geographic area. That number is than multiplied by 100,000. Age adjusted rates are calculated by multiplying the age-specific death rate for each age group by the corresponding weight from the 2000 standard population, summing across all age groups, and then multiplying this result by 100,000.
View by Month and Year
Users can view by year to see tables and charts of the number and rate of CO hospitalizations in New York State. Users can view by month to see tables and charts displaying the sum of CO hospitalizations in New York State by month from 2000-2006. These data show annual and seasonal trends in CO hospitalizations and relationship between colder weather and CO poisoning.
View by Region
Users can view by region to see tables and charts comparing the number and rate of CO hospitalizations in New York State Excluding New York City and New York City.
View by Place of Exposure
Users can view by place of exposure to show a table and chart with the distribution of CO hospitalizations by ICD-09 Place-of-injury code. These data show that most CO poisonings occur from exposures at home.
View by Cause
Users can view by cause to see a table and chart with the CO hospitalization rate by fire-relatedness. The user can view these data for the entire state or for New York State excluding New York City and New York City. These data show the difference in CO hospitalizations and the potential sources of exposure for each region.
View by CO Age-Adjusted Mortality by Year
Users can view by year to see tables and charts with the number and rate of CO deaths in NYS by year and can better understand trends in CO mortality.
Technical Notes
Hospitalizations:
- Data on carbon monoxide are extracted from SPARCS.
- A CO hospitalization is defined as having an International Classification of Diseases, 9th Revision, Clinical Modification (ICD-9-CM) code of 986 or ICD-9-CM External Cause-of-Injury code (E-code) E8682, E8683, E8688, E8689, E9520, E9521, E9820, E9821 in any of the SPARCS diagnosis fields or the E-code field.
- CO hospitalization years and months are based on hospital admission date. Because a SPARCS record is not generated until a patient is discharged from the hospital, 2006 data may not include some individuals who were hospitalized in 2006 but were not discharged until 2007.
- Population estimates used for calculating CO hospitalization rates were taken from the U.S. Census Bureau. Annual population estimates for 2000-2006 are taken from Census 2009 Population Estimates. State hospitalization rates by demographic variables are based on Census 2000 Summary File 1 (SF 1) 100-Percent Data. New York State regional hospitalization rates are based on 7/1/2006 County Characteristics Resident Population Estimates File, CC-EST2006-ALLDATA-36.csv, available at Population Estimates Data Sets. CO hospitalization rates were calculated per 100,000 residents.
- Non-NYS residents who were hospitalized in NYS for CO poisoning have been excluded.
- Hospitalizations for intentional CO poisoning have been excluded.
Mortality:
- Data on CO deaths are extracted from CDC-WONDER Multiple Cause of Death files. For more information on WONDER Multiple Cause of Death Files, visit the WONDER website.
- Each death certificate contains a single underlying cause of death, up to twenty additional multiple causes, and demographic data. CO deaths were extracted by querying all records with multiple cause of International Classification of Diseases, 10th Revision, Clinical Modification (ICD-10-CM) code 'T58' along with a CD-10-CM External Cause-of-Injury code (E-code) related to a transportation accidents (V01-V99), other accidental cause of external injury (W00-X59), sequelae of transportation or other accidents (Y85-Y86), or event of undetermined intent (Y10-Y34).
- The age-adjusted rate produced in the WONDER MCD files is calculated by multiplying the age-specific death rate for each age group by the corresponding weight from the 2000 standard population, summing across all age groups, and then multiplying this result by 100,000 (or whatever multiplier is specified in the query).
- Age-Adjusted Death Rate = Sum of (Age Specific Death Rate * Standard Population weight) * 100,000.
- CO deaths by intentional causes have been excluded.
