G
Glossary


Active surveillance.

For adverse event reporting, programs that include direct involvement by the sponsor (e.g., U.S. Food and Drug Administration [FDA]) in collecting information, for example, through routine or special surveys. (See also Passive surveillance.)

Adolescent.

As defined by FDA in connection with medical devices, an individual between the ages of 12 and 20 (“up to 21” years).

Adverse event.

An instance of harm during patient care or research that is not the result of the individual’s disease or medical condition. Adverse events are sometimes defined to include events that have the potential to cause harm, such as close calls or near misses that could have resulted in harm but did not.

Approval.

Authorization to market a medical device that requires submission of a premarket approval application (PMA) and FDA review of safety and effectiveness.


Benefit.

A positive or valued outcome of an action or event.


Child.

As defined by FDA in connection with medical devices, an individual between the ages of 2 and 11 (“up to 12” years).

Class I medical devices.

Low-risk devices that need not be reviewed by FDA before marketing As specified in statute, these are (1) devices for which certain “general” controls, for example, standards for good manufacturing practices, are considered to provide reasonable assurance of the safety and effectiveness of the device or (2) devices that are not intended or represented (“purported”) to support or sustain life or play an important role in preventing impairment or that are not

expected to pose an unreasonable risk of illness or injury. (21 USC 360c(a)(1)(A))

Class II medical devices.

Devices that present more risk than Class I devices (see above). For these devices, general controls are not by themselves sufficient to provide reasonable assurance of safety and effectiveness, but sufficient information is available to develop “special controls” (for example, guidelines) for that purpose (21 USC 360(c)(a)(1)). For a Class II device to be legally marketed, the manufacturer must usually submit a notification of intent to market and receive FDA clearance under 510(k) provisions (referring to the applicable section of the Medical Device Amendments of 1976. (21 USC 360(k))

Class III medical devices.

Devices that are intended to support or sustain life or play an important role in preventing impairment or that are considered to pose an unreasonable risk of illness or injury. For devices in this class, FDA has determined that general controls are inadequate to reasonably assure safety and effectiveness and that available information is insufficient to develop adequate special controls. (21 USC 360(c)(a)(1)) Class III devices usually require FDA approval.

Clearance.

A process for FDA to authorize a device for marketing based on a review of evidence of safety and equivalence to certain previously marketed devices; clinical evidence of safety and effectiveness is not usually required.

Clinical trial.

A prospective study involving human subjects that is designed to evaluate a health care intervention (e.g., device therapy, diagnostic test).

Close call

(see Near miss).

Combination product.

A product that (1) is comprised of two or more regulated components, i.e., drug/device, biologic/device, drug/biologic, or drug/device/biologic, that are physically, chemically, or otherwise combined or mixed and produced as a single entity; (2) is comprised of two or more separate products packaged together in a single package or as a unit and comprised of drug and device products, device and biological products, or biological and drug products; or (3) is packaged separately that according to its investigational plan or proposed labeling is intended for use only with an approved individually specified drug, device, or biological product where both are required to achieve the intended use, indication, or effect and where upon approval of the proposed product the labeling of the approved product would need to be changed, e.g., to reflect a change in intended use, dosage form, strength, route of administration, or significant change in dose. (21 CFR 3.2(e))

Compassionate use.

A mechanism for securing FDA permission for the use with an individual patient of a medical device that has not been approved or cleared for marketing. (See also Emergency use.)

Processes including evaluations, decisions, and other activities that occur prior to the marketing of a medical product.

Premarket notification (510(k) process).

Process for securing FDA clearance to market devices that are substantially equivalent to devices marketed prior to May 28, 1976. 510(k) refers to the relevant section of the Federal Food, Drug, and Cosmetic Act.

Public health notification.

An FDA announcement used to quickly disseminate device-related safety information beneficial to healthcare providers. Recently the FDA decided to comprehensively apply the term to what had been distinguished as Safety Alerts, Public Health Notifications, and Public Health Advisories.


Quality systems regulation.

General control requirements that cover methods, facilities and controls related to medical device design (prior to actual production), manufacture, packing, storage, and installation. These regulations include Good Manufacturing Practices and seek to prevent safety problems related to design deficiencies.


Rare condition.

include performance standards, guidelines, patient registries, and postmarket surveillance. (FDCA section 513(a)(1)(B))

Substantially equivalent.

When a device (a) has same intended use and has same technological characteristics as a predicate device, OR (b) has the same intended use but different technological characteristics if these differences do not raise different questions of safety and effectiveness and if information is provided to show that the device is as safe and effective a legally marketed device.

Surveillance.

The ongoing, systematic collection, analysis, interpretation, and dissemination of data about a health-related event for use in public health action to reduce morbidity and mortality and to improve health (CDC, 2001).


Trade Secret.

Information that may consist of any commercially valuable plan, formula, process, or device that is used for the making, preparing, compounding, or processing of trade commodities and that can be said to be the end product of either innovation or substantial effort. There must be a direct relationship between the trade secret and the productive process.


Unlabeled use.

Use of a drug or medical device for a purpose, patient group, or other use that is not specifically approved by the FDA for use as indicated on the product’s label. Such use by physicians is considered part of the practice of medicine, which FDA—by statute—does not regulate. Sometimes described as “off-label” use.

User facility.

A hospital, an ambulatory surgical facility, a nursing home, an outpatient diagnostic facility, or an outpatient treatment facility that is not a physician’s office. An outpatient treatment facility includes home health care groups, ambulance providers, and rescue services. (21 CFR 803.3(f) & (v))

Innovative medical devices have helped reduce the burden of illness and injury and improve the quality of life for countless children. Mechanical ventilators and other respiratory support devices rescue thousands of fragile newborns every year. Children who once would have died of congenital heart conditions survive with the aid of implanted pacemakers, mechanical heart valves, and devices that close holes in the heart. Responding to a Congressional request, the Institute of Medicine assesses the system for postmarket surveillance of medical devices used with children. The book specifically examines:

  • The Food and Drug Administration's monitoring and use of adverse event reports
  • The agency's monitoring of manufacturers' fulfillment of commitments for postmarket studies ordered at the time of a device's approval for marketing
  • The adequacy of postmarket studies of implanted devices to evaluate the effects of children's active lifestyles and their growth and development on device performance

Postmarket surveillance of medical devices used with children is a little investigated topic, in part because the market for most medical products is concentrated among older adults. Yet children differ from adults, and their special characteristics have implications for evaluation and monitoring of the short- and long-term safety and effectiveness of medical devices used with young patients.
