INTRODUCTION

Purpose and Background
Every year in the United States, there are approximately 235 million visits made to hospital emergency and
outpatient departments, and hospital-based ambulatory surgery centers. However, adequate data on the
hospital component of ambulatory medical care did not exist until the initiation of the National Hospital
Ambulatory Medical Care Survey (NHAMCS) by the Centers for Disease Control and Prevention’s (CDC)
National Center for Health Statistics (NCHS) in December 1991. This study is the principal source of
information on the utilization of hospital emergency departments (EDs), outpatient departments (OPDs),
and hospital-based ambulatory surgery centers (ASCs) which were added to NHAMCS in 2009.
Moreover, it is the only source of nationally representative estimates on the demographic characteristics of
outpatients, diagnoses, diagnostic services, medication therapy, and the patterns of use of emergency and
outpatient services in hospitals which differ in size, location, and ownership. Data collected through this
study are essential to plan health services, improve medical education, and determine health care workforce
needs.
The study of hospital-based ambulatory care is one of several health care studies sponsored by the CDC’s
National Center for Health Statistics. The National Hospital Ambulatory Medical Care Survey
complements the National Ambulatory Medical Care Survey which collects data on patient visits to
physicians in office-based practices. The hospital study is now bridging the gap which existed
in coverage of ambulatory care data and is further expanding its uses. This need is further accentuated by
the increasing efforts at cost containment, the rapidly aging population, the growing number of persons
without health insurance, and the introduction of new technologies. The American College of Emergency
Physicians, Society for Academic Emergency Medicine, Emergency Nurses Association, American
College of Osteopathic Emergency Physicians, Surgeon General’s Office, and Federation of American
Hospitals have endorsed this study. Letters of endorsement are provided in Exhibits A, B, C, D, E and F
on pages E-1 to E-6.

Scope
An annual sample of approximately 480 hospitals across the country is selected for participation in the
National Hospital Ambulatory Medical Care Survey. Each hospital collects data for a specified 4-week
period in the survey year. These hospitals are revisited in subsequent years to measure changes in the
public's use of ambulatory medical care services from year to year. Eligible hospitals consist of nonfederal, short-stay, and general hospitals with emergency service areas and/or outpatient clinics and/or
ambulatory surgery centers.
The study includes a sample of ambulatory units, that is, emergency service areas, outpatient clinics, and
ambulatory surgery centers within each hospital. Medical care must be provided by or under the direct
supervision of a physician for the unit to be considered eligible. Dental clinics, physical, speech, and
occupational therapy, podiatry, optometry, social work, and other clinics where physician services are not
typically provided are not included. Ancillary services, such as pharmacy, diagnostic x-ray, or radiation
therapy are also excluded from the study. Private practice offices and facilities that might have some
association with the hospital, but are not considered hospital clinics are ineligible.

2

Study Roles
The National Center for Health Statistics has contracted with the U.S. Census Bureau to implement the
data collection activities for the National Hospital Ambulatory Medical Care Survey. Trained Census
Bureau field representatives will:

contact selected hospitals to screen them for eligibility and arrange an appointment with the
hospital administrator or other designated representative to further discuss the study;

assist the hospital as requested in obtaining the necessary approval for participation in the study;

obtain basic information on the hospital's emergency and outpatient departments and
ambulatory surgery centers, and select the ambulatory care units to be included in the data
collection;

show hospital staff how to select a sample of patient visits and record the data; and

monitor the data collection procedures during the reporting period.

We are asking the hospital staff to do the following two activities:

select a sample of patient visits during a specific 4-week reporting period following the specific
sampling guidelines provided; and

complete a one-page form for each selected visit.

A Census Bureau field representative will visit each week to resolve any problems with sampling patient
visits or completing Patient Record forms, and to collect any forms already completed. If any problems
arise, or assistance is otherwise needed between these weekly visits, contact the field representative or
other contact (as listed in items D and E on page 1) immediately.

Data Uses
As mentioned earlier, the information collected on patient visits to hospital emergency and outpatient
departments and ambulatory surgery centers through the National Hospital Ambulatory Medical Care
Survey will complement the study of physician office-based ambulatory care. The uses of OPD data are
shown in EXHIBIT G on page E-7. The list of data users is quite extensive and includes medical
associations, universities and medical schools, government agencies, and broadcast and print media.

Authorization and Assurance of Confidentiality
The National Center for Health Statistics has authority to collect data concerning the public's use of
physicians' services under Section 306 (b) (1) (F) of the Public Health Service Act (42 USC 242k).
Any identifiable information will be held confidential and will only be used by NCHS staff, contractors, or
agents, only when necessary and with strict controls, and will not be disclosed to anyone else without the
consent of your hospital. By law, every employee as well as every agent has taken an oath and is subject to
a jail term of up to five years, a fine up to $250,000, or both if he or she willfully discloses ANY
identifiable information about your hospital’s patients. Furthermore, the names or any other identifying
information for individual patients are never collected. Assurance of confidentiality is provided to all
respondents according to Section 308 (d) of the Public Health Service Act (42 USC 242m).
The requirements of the Health Insurance Portability and Accountability Act (HIPAA) Privacy Rule on
health information permits you to make disclosures of protected health information without patient
authorization for (1) public health purposes, or (2) research that has been approved by an Institutional
Review Board, or (3) under a data use agreement with NCHS. There are several things that you must do to
assure compliance with the Privacy Rule including providing a privacy notice to your patients that
indicates that patient information may be disclosed for either research or public health purposes, and a
record that a disclosure of information to CDC for the NHAMCS was made. More specific information
can be obtained about Privacy Rule disclosure requirements on our website mentioned below.
NHAMCS Participant Web Page
The National Center for Health Statistics has a web page devoted to the common questions and concerns of
hospital staff participating in the National Hospital Ambulatory Medical Care Survey. The participant web
site can be accessed by logging on to www.cdc.gov/nhamcs. Refer to EXHIBIT J on page E-10 for the

SECTION III

SAMPLING

Overview
The hospitals, clinics, and visits chosen for the study are selected by well-established statistical methods.
The sample design is comprised of multiple stages to ensure that the sample of hospitals, clinics, and visits
selected are representative of those throughout the United States. The participation of each hospital is
crucial, since each hospital in the sample represents many others in the country. Within the hospital,
ambulatory units are selected. In large outpatient departments (containing more than 5 clinics), statistical
sampling methods are also used to select a sample of up to 12 of these clinics. In each of the selected
outpatient clinics, a sample of patient visits is chosen.
Keeping respondent burden and survey costs as low as possible are always important considerations when
designing a study. Sampling allows us to make national estimates of the volume and characteristics of
patient visits from a small sample of visits to clinics and hospitals, while reducing both the cost of the
study and the work asked of the hospital staff. However, sampling procedures must be implemented
accurately or large errors will result, adversely affecting the data. The National Center for Health Statistics
selects the hospitals to be used for the study. If clinic sampling is necessary for the outpatient department,
Census Bureau staff will select these units. However, the responsibility for sampling patient visits within
the selected clinics lies with the hospital staff. Procedures for selecting patient visits have been designed
to be simple and easy to implement. Census Bureau field representatives will instruct the hospital staff on
these procedures.
Patient visits are systematically selected over the 4-week reporting period. The sampling procedures are
designed so that on average, approximately 150 to 200 visits from the outpatient department. The sampled
visits in the outpatient department are spread over the selected clinics, if the hospital has multiple clinics.
The number of visits sampled for each clinic is dependent on the clinic's patient volume.
Listing Patient Visits
A daily listing of all patient visits must be kept or constructed by each participating unit so that a sample of
visits can be selected using the prescribed methods. The list of patient visits may be taken from an arrival
log or other source of recording patient visits. The order in which the patients are listed is not important.
However, it is crucial to have a complete listing of all patients receiving treatment during all hours of
operation. The list should include those patients who came without previously being scheduled, but it
should exclude persons who canceled appointments or were "no shows." The Census Bureau field
representative will review the method used for listing patient visits (or constructing patient lists) in each
unit to determine if patient sampling can be done properly. In some instances, the Census Bureau field
representative will provide an Optional Patient Log (EXHIBIT H on page E-8) to assist the ambulatory
unit with visit sampling.
Once visit sampling begins, the order of the names must not change. Sampling procedures require that
each visit be selected at a predetermined interval (for example, every 2nd patient, every 10th patient, every
15th patient, etc.). This is the "Take Every" pattern. If a patient is inserted into the list after sampling has
already been done, the pattern will be off and the visits must be resampled.

5

Eligible Visits
A "visit" is defined as a direct, personal exchange between an ambulatory patient and a physician, or a staff
member acting under the direct supervision of a physician, for the purpose of seeking care and rendering
health services. Visits solely for administrative purposes and visits in which no medical care is provided
are not eligible. The following are types of visits/contacts which should be excluded:

persons who visit only to leave a specimen, pick up a prescription or medication, or other visit
where medical care is not provided;

persons who visit to pay a bill, complete insurance forms, or for some other administrative
reason;

telephone or e-mail messages calls from patients; and
visits by persons currently admitted as inpatients to any other health care facility on the
premises, that is, the sample hospital.

It may be helpful to provide a brief reason for the patient's visit on the patient visit list/log to ensure the
exclusion of these visits from the sample. If you discover that an ineligible visit has been accidentally
included in the sample and a Patient Record form has been completed, write "VOID" in the white space of
the top margin of the Patient Record form to the right of the “Incorrect” box. For visits with a disposition
of “No show/Left without being seen,” do NOT write “VOID” on the top margin of the Patient Record
form as these forms are keyed. Do NOT write “VOID” ACROSS the Patient Record form for any reason.
Sampling Procedures
The 4-week reporting period for this unit is recorded on the cover of this booklet. It includes the date for
beginning data collection, as well as the date for completing data collection. To determine which patient
visit to sample first, refer to the instructions at the bottom of this booklet's cover. The first part of the
instruction directs staff to begin with the patient listed on a specific line number of the log on the first day
of data collection. Locate this patient visit on the list and mark the name to indicate that it is the first
patient visit sampled.
To continue sampling, refer once again to the instructions on the cover. Select every nth patient.
Continue counting down the patient list until you arrive at the nth patient name listed. This is the second
patient selected for the sample. This process is repeated to select subsequent patient visits for the sample.
For example, if the sampling instructions indicate that you begin with the 3rd patient listed, and select
every 15th patient, you would select the 3rd, 18th, 33rd and so forth. See EXHIBIT H on page E-8 for an
Optional Patient Log marked with an example of a sampling pattern. Be sure to follow the sampling
pattern given on the cover of this booklet.
After each selection, mark or circle the patient name to indicate its inclusion in the sample, and to indicate
where to begin for sampling the next patient visit. The “Take Every” pattern remains consistent
throughout the remainder of the reporting period and should be followed continuously (from shift to shift,
and day to day). Do not start fresh with a new "Start With" after the end of a shift or day.

SECTION IV

COMPLETING PATIENT RECORD FORMS

Organizing Visit Sampling and Data Collection
A Patient Record form is completed for every patient visit selected in the sample during the 4-week
reporting period. The OPD Patient Record form is a one-page form consisting of 12 items which require
only short answers. It should take approximately six minutes to complete each form. These forms will
require even less time to complete as staff become more familiar with the items. The sampling procedures
are designed so that the outpatient department of average size will complete approximately 150 to 200
Patient Record forms during the reporting period. If multiple clinics exist within the outpatient
department, forms are distributed among the various clinics.
The Patient Record forms may be completed either during the patient's visit, immediately after the patient's
visit, at the end of the shift, day, etc., or in some combination of these, whichever is most convenient for
the staff. In some cases, a nurse or clerk may furnish the information for certain items prior to the patient's
visit, leaving the remainder of the items to be completed by the attending health care provider during or
immediately after the visit. In other situations, it may be more convenient to complete all records at the
end of the shift or day by one designated person. Whatever method you choose, it is strongly suggested
that the forms be completed at least on a daily basis. Retrieving the records at a later date may prove to be
difficult and time-consuming. Also, patient information will be fresher in the minds of the staff in case
clarification is needed.
Staff members completing Patient Record forms must be familiar with medical terms and procedures since
most items on the form are clinical in nature. They must also know where to locate the information
necessary for completing the forms. To ensure that complete coverage is provided for all shifts and days,
the responsibility for data collection may require the participation of several staff. We ask that each
participating clinic appoint a Data Coordinator to coordinate the personnel involved in the study and their
activities. The Data Coordinator's responsibilities will include supervising and/or conducting the selection
of the sample visits and the completion of the Patient Record forms.
Prior to the clinic's assigned reporting period, the Census Bureau field representative will meet with the
director of each clinic and discuss the organization of sampling and the process of completing the Patient
Record forms. The director then determines which staff will be needed in the data collection activities.
The Census Bureau field representative will train the staff on sampling and data collection.

7

Completing the Patient Record Form
The OPD Patient Record form consists of two sections separated by a perforated line. (See EXHIBIT I on
page E-9 for an example of the OPD Patient Record form.) The top section of the form contains two items
of identifying information about the patient - the patient's name and the patient’s medical record number.
It is helpful to enter the information for these items immediately following the selection of the patient visit
into the sample. The top section of the form remains attached to the bottom until the entire form is
completed. To ensure patient confidentiality, hospital staff should detach and keep the top section before
the Patient Record forms are collected by the Census Bureau field representative. The Data Coordinator
should keep this portion of the form for a period of four weeks following the reporting period. Should the
field representative discover missing or unclear information while editing the forms, he or she may
recontact the Data Coordinator to retrieve this information. The top section can be matched to the bottom
by the seven-digit identification number (beginning with 2) printed on both sections of the form. The field
representative will give you this identification number when requesting information.
The bottom section of the OPD form consists of 12 brief items designed to collect data on the patient's
demographic characteristics, reason for visit, diagnosis, etc. Item-by-item instructions begin on page 9 of
these instructions. To ensure patient confidentiality, please do not record any patient identifying
information on the bottom portion of the form.
Each outpatient department clinic receives a folio containing a pad of Patient Record forms specifically
assigned to that clinic. An ample supply of forms is included in the event that some are damaged or
destroyed, or the clinic sees a much higher volume of patient visits than expected. Should the supply of
forms for this clinic run low, please contact the Census Bureau field representative or other contact
provided in items D and E on page 1 of this booklet. Do not borrow Patient Record forms from other
participating emergency service areas, clinics, or ambulatory surgery centers in this hospital. Check
the Patient Record forms to make sure that they are lavender and have "Outpatient Department"
printed at the top.

REASON FOR VISIT

ITEM 3. PATIENT’S COMPLAINT(S), SYMPTOM(S), OR OTHER REASON(S) FOR THIS
VISIT (use patient’s own words)
Enter the patient's complaint(s), symptom(s), or other reason(s) for this visit in the patient's own
words. Space has been allotted for the “most important” and two “other” complaints, symptoms, and
reasons as indicated below.
(1) Most important
(2) Other
(3) Other
The Most Important reason should be entered in (1). Space is available for two other reasons in (2)
and (3). By “most important” we mean the problem or symptom which in the physician's judgment
was most responsible for the patient making this visit. Since we are interested only in the patient's
most important complaints/ symptoms/ reasons, it is not necessary to record more than three.
This is one of the most important items on the Patient Record form. No similar data on OPD visits
are available in any other survey and there is tremendous interest in the findings. Please take the
time to be sure you understand what is wanted--especially the following three points:
♦

We want the patient's principal complaint(s), symptom(s), or other reason(s) in the patient’s
own words. The physician may recognize right away, or may find out after the examination,
13

♦

♦

that the real problem is something entirely different. In item 3 we are interested in how the
patient defines the reason for the visit (e.g., “cramps after eating,” or “fell and twisted my
ankle”).
The item refers to the patient’s complaint, symptom, or other reason for this visit. Conceivably,
the patient may be undergoing a course of treatment for a serious illness, but if his/her principal
reason for this visit is a cut finger or a twisted ankle, then that is the information we want.
There will be visits by patients for reasons other than some complaint or symptom. Examples
might be well baby check-up or routine prenatal care. In such cases, simply record the reason
for the visit.

Reminder: If the reason for a patient's visit is to pay a bill, ask the physician to complete an
insurance form, or drop off a specimen, then the patient is not eligible for the sample. A Patient
Record form should not be completed for this patient.

4.

CONTINUITY OF CARE

ITEM 4a.

IS THIS CLINIC THE PATIENT’S PRIMARY CARE PROVIDER?

The primary care provider plans and provides the comprehensive primary health care of the patient.
Mark “Yes” if the health care provided to the patient during this visit was from his/her primary care
provider and skip to item 4b. If the provider seen at this visit was substituting for the primary care
provider, also check “Yes.” Mark “No” if care was not from the primary care provider or
“Unknown” if it is not known.
If “No” or “Unknown” is checked, also indicate whether the patient was referred for this visit by
another health care provider. This item provides an idea of the “flow” of ambulatory patients
from one provider to another. Mark the “Yes,” “No,” or “Unknown” category, as appropriate.
Notice that this item concerns referrals to the sample clinic by a different provider or clinic. The
interest is in referrals for this visit and not in referrals for any prior visit.
Referrals are any visits that are made because of the advice or direction of a clinic or
physician/provider other than the clinic or physician/provider being visited.

ITEM 4b.

HAS THE PATIENT BEEN SEEN IN THIS CLINIC BEFORE?

“Seen” means “provided care for” at any time in the past. Mark “Yes, established patient” if the
patient was seen before by any provider in the clinic. Exclude this visit.
Mark “No, new patient” if the patient has not been seen in the clinic before.

14

If “Yes” is checked, also indicate approximately how many past visits the patient has made to
this clinic within the last 12 months using the write-in box provided. Do not include the current
visit in your total. If you cannot determine how many past visits were made, then mark
“Unknown.” Include all visits to other providers in this clinic.

15

ITEM 4c.

MAJOR REASON FOR THIS VISIT

Mark the major reason for the patient’s current visit. Be sure to check only one of the following
“Major Reasons:”

5.
