    Thank you for your question.

    I want to preface this by saying that the National Center for Health Statistics is a Federal Statistical Agency and as such we cannot give advice on diet, exercise, etc.

    One of the other agencies within our parent organization, the Centers for Disease Control and Prevention, the National Center for Chronic Disease Prevention and Health Promotion has a lot of resources on its website.

    Thank you for your question.

    We compile data on the number of hip replacement that took place, but we have no information on the length of time it took for a physican to do hip surgery. The National Survey of Ambulatory Surgery will begin publishing this data in early 2008.

  11. Rick Berg says:

    I understand that 38,000 Americans are snake-bitten each year, and about 8,000 are by poisonous snakes, with 3,000 being “illegitimate” bites (people handling/catching).
    Of the 5-8 people who die each year, how many are bitten by non-native species?
    Of the 5-8 people who die each year, how many are bitten by pet snakes?

  12. mcox1 says:

    Brenda and Rick,

    At NCHS, we track mortality from snake bites, but items such as “pet” or “non-native” are not part of ICD-10 codes (cause-of-death codes). For more injury-related information, check out the National Center for Injury Prevention and Control at Where did you acquire your data, Rick?

    I’ve got a question:
    I am looking for historical data on the number of myocardial infarction (i.e. Heart Attacks) per year in the US.
    If you know the number of PCI (Percutaneous Coronary Intervention) that are performed in those people, that’s even better.
    I appreciate your help and look forward to hearing back,

  14. Megan Cox says:


    We would either have this data by cause of death or hospital visits. We would also need to know how far back you want to look. You can always contact our pressroom for more immediate answers.
