The 2009 survey contains information from 32,281 patient visits to 1,293 physicians' offices. Data are available on the patient's smoking habits, reason for the visit, expected source of payment, the physician's diagnosis, and the kinds of diagnostic and therapeutic services rendered. Other variables include information on the following: drugs/medications ordered, administered, or provided during office visits; information on medication code, generic name and code, brand name, entry status, prescription status, federal controlled substance status, composition status, and related ingredient codes. Information is also included on the physician's specialization and geographic location. Demographic information on patients, such as age, sex, race, and ethnicity, was also collected. 2009 2009 United States Office visits made within the United States by patients of nonfederally-employed physicians who were primarily involved in office-based patient care activities, but not engaged in the specialties of radiology, pathology, or anesthesiology. administrative records data medical records The 2009 NAMCS utilized a multistage probability sample design. Primary sampling units (PSU's) were selected in the first stage; physician practices within PSU's in the second stage; and patient visits to selected physicians in the third stage. Additional information regarding sampling methodology can be found in the study documentation. record abstracts medical records Microdata file users should be fully aware of the importance of the "patient visit weight" (PATWT) and how it must be used. Information about the patient visit weight, along with a "physician-level weight" (PHYSWT), is presented in the codebook. If more information is needed, the staff of the Ambulatory Care Statistics Branch can be consulted by calling (301) 458-4600.

ICPSR data undergo a confidentiality review and are altered when necessary to limit the risk of disclosure. ICPSR also routinely creates ready-to-go data files along with setups in the major statistical software formats as well as standard codebooks to accompany the data. In addition to these procedures, ICPSR performed the following processing steps for this data collection:

Created variable labels and/or value labels.Created online analysis version with question text.Performed recodes and/or calculated derived variables.Checked for undocumented or out-of-range codes. Per agreement with the National Center for Health Statistics (NCHS), ICPSR distributes the data file and text of the technical documentation for this collection as prepared by NCHS. The Stata dataset (.dta file) made available by ICPSR does not contain all of the value labels found within the .do file supplied by ICPSR. Specifically, the value labels that are composed primarily of ICD-9 codes have been omitted from the .dta file. Those data users interested in applying the value labels to the dataset will be able to edit the Stata setup files, which include the aforementioned labels, provided by ICPSR. 62.1 percent unweighted response rate, 62.4 percent weighted response rate Ann Arbor, Mi.: Inter-university Consortium for Political and Social Research Additional special permissions, where applicable, are described in the restrictions field. In preparing the data file for this collection, the National Center for Health Statistics (NCHS) has removed direct identifiers and characteristics that might lead to identification of data subjects. As an additional precaution, NCHS requires, under section 308(d) of the Public Health Service Act (42 U.S.C. 242m), that data collected by NCHS not be used for any purpose other than statistical analysis and reporting. NCHS further requires that analysts not use the data to learn the identity of any persons or establishments and that the director of NCHS be notified if any identities are inadvertently discovered. ICPSR member institutions and other users ordering data from ICPSR are expected to adhere to these restrictions.

The Public Health Service Act (42 U.S.C. 242m(d)) provides that the data collected by the National Center for Health Statistics (NCHS) may be used only for the purpose for which they were obtained; any effort to determine the identity of any reported cases, or to use the information for any purpose other than for health statistical reporting and analysis, would violate this statutory restriction and the conditions of the data use agreement. NCHS does all it can to ensure that the identity of data subjects cannot be disclosed; as well as characteristics that might lead to identifications are omitted from the data set. Nevertheless, it may be possible in a rare instance, through complex analysis, and with outside information, to ascertain from the data sets the identity of particular persons or establishments.

Considerable harm could ensue if this were done.
