National Ambulatory Medical Care Survey, Public-use file, 1973-2019

The National Ambulatory Medical Care Survey (NAMCS) is a national survey designed to meet the need for objective, reliable information about the provision and use of ambulatory medical care services in the United States. Findings are based on a sample of visits to non-federally employed office-based physicians who are primarily engaged in direct patient care. Physicians in the specialties (including designated sub-specialties) of anesthesiology, pathology, and radiology are excluded from the survey. The survey was conducted annually from 1973 to 1981, again in 1985, and annually since 1989. 
Data collection from the physician, rather than from the patient, provides an analytic base that expands information on ambulatory care collected through other NCHS surveys. Data about the physician and their practice characteristics are collected during a survey induction interview.
For survey years 1973 to 1991, there are two data files: one for patient visit data and a second for drug mention data. The second file is limited to those visits with mention of medication therapy. For the 1991 data, it is possible to link information on the drug file with information on the patient visit file. Beginning with the 1992 survey year through 2011, one main data file was produced annually that contains both patient visit and drug information.

National Hospital Discharge Survey (NHDS) Restricted Data, 1965-2010

The National Hospital Discharge Survey (NHDS), conducted from 1965 to 2010, was a national probability survey designed to meet the need for information on characteristics of inpatients discharged from non-Federal short-stay hospitals in the United States. From 1988-2007 the NHDS collected data from a sample of approximately 270,000 inpatient records acquired from a national sample of about 500 hospitals. From 2008 to 2010 the sample size was reduced to 239. Only hospitals with an average length of stay of fewer than 30 days for all patients, general hospitals, or children’s general hospitals are included in the survey. Federal, military, and Department of Veterans Affairs hospitals, as well as hospital units of institutions (such as prison hospitals), and hospitals with fewer than six beds staffed for patient use, are excluded.

Beginning in 1988, two data collection procedures have been used in the survey. The medical abstract form and the automated data tapes contain items that relate to the personal characteristics of the patient. These items include age, sex, race, ethnicity, marital status, and expected sources of payment. Administrative items such as admission and discharge dates (which allow calculation of length of stay), as well as discharge status are also included. Medical information about patients includes diagnoses and procedures coded to the International Classification of Diseases, 9th Revision, Clinical Modification (ICD-9-CM).
National Ambulatory Medical Care Survey, Health Center Component, 2021-2022, restricted data

The National Ambulatory Medical Care Survey (NAMCS) is designed to meet the need for objective, reliable information about the provision and use of ambulatory medical care services in the United States. NAMCS began in 1973 as a national probability sample survey of visits to nonfederally employed office-based physicians. NCHS conducted the survey annually through 1981, again in 1985, and annually through 2021 (collection of visit data from physicians was stopped during 2020–2021 due to the burden placed on respondents by the COVID-19 pandemic). In 2006, a separate sample of Community Health Centers (CHCs) was added to the survey; the CHC component samples visits to both physicians and advanced practice providers (nurse practitioners, PAs [physician assistants and physician associates], and certified nurse midwives). Starting in 2012, in addition to the traditional NAMCS file, a separate data file for CHCs including physicians and advanced practice providers has been released.

In 2021, the former CHC sample of NAMCS was redesigned and launched as the NAMCS Health Center (HC) Component, collecting visit data from HCs using electronic health records, or EHR, systems of the participating health centers. The NAMCS Health Center Component contains critical data about health centers and the care they provide.

National Hospital Ambulatory Medical Care Survey, Public-use data 1992-2022

The National Hospital Ambulatory Medical Care Survey (NHAMCS) has been fielded annually since 1992 to collect data on the utilization and provision of ambulatory care services in hospital emergency and outpatient departments. Data collection from hospital-based ambulatory surgery centers began in 2009. And between 2010 and 2012 NHAMCS gathered data on visits to freestanding ambulatory surgery centers. In 2018, the survey began focusing on just the ambulatory visits made to emergency departments.
Each emergency department is randomly assigned to a 4-week reporting period. During this period, data for a systematic random sample of visits are recorded by Census interviewers using a computerized Patient Record Form. Data are obtained on patient characteristics such as age, sex, race, and ethnicity, and visit characteristics such as patient’s reason for visit, provider’s diagnosis, services ordered or provided, and treatments, including medication therapy. In addition, data about the facility are collected as part of a survey induction interview.
Medicare Inpatient Hospitals - by Provider and Service

The Medicare Inpatient Hospitals by Provider and Service dataset provides information on inpatient discharges for Original Medicare Part A beneficiaries by IPPS hospitals. It includes information on the use, payment, and hospital charges for more than 3,000 U.S. hospitals that received IPPS payments. The data are organized by hospital and Medicare Severity Diagnosis Related Group (DRG).

 

Hospitals determine what they will charge for items and services provided to patients, and these charges are the amount the hospital bills for an item or service. The Total Payment Amount includes the DRG amount, claim per diem amount, beneficiary primary payer claim payment amount, beneficiary Part A (Hospital Insurance) coinsurance amount, beneficiary deductible amount, beneficiary blood deductible amount and diagnosis related group outlier amount.

National Ambulatory Medical Care Survey: Electronic Medical Records Supplement, 2008-2011, Restricted

The National Electronic Health Records Survey (NEHRS) is an annual survey of non-federally employed, office-based physicians practicing in the United States (excluding those in the specialties of anesthesiology, radiology, and pathology). NEHRS began in 2008 and was originally designed as an annual mail supplement to the National Ambulatory Medical Care Survey (NAMCS). Prior to 2012, NEHRS was a supplement to the NAMCS, referred to as the NAMCS Electronic Medical Records Supplement. The annual data collected was similar to NEHRS and may be analyzed as a distinct dataset.

The National Ambulatory Medical Care Survey (NAMCS) Health Center Component, conducted by the National Center for Health Statistics (NCHS), collects annual data on visits to health centers to describe patterns of utilization and provision of ambulatory care delivery in the United States. Health centers are local clinics that are community-based and provide comprehensive health care services to populations that are often vulnerable and underserved.

2023 Respiratory Virus Response - NSSP Emergency Department Visit Trajectories by State- COVID-19, Flu, RSV, Combined

2023 Respiratory Viruses Response – National Syndromic Surveillance Program Emergency Department Visit Trajectories - COVID-19, Flu, RSV, Combined – by state. This dataset provides the percentage of emergency department patient visits for the specified pathogen of all ED patient visits for the specified geography that were observed for the given week from data submitted to the National Syndromic Surveillance Program (NSSP). In addition, the trend over time both as of the given row date and as of the most current data submitted is characterized as increasing, decreasing or stable to provide awareness of how the weekly trend is changing for the given geographic region.

For the emergency department time series, trajectory classifications reported on the opening page are based on rolling regression model assessments of the slope for each respiratory illness. Weeks with a significant time term (p <0.05) are classified as increasing when the slope is positive and decreasing when the slope is negative. Weeks with a non-significant time term (p ≥ 0.05) are classified as stable. A 3-week moving average is applied to the time series prior to the regression procedure in order to smooth week-to-week variation.
