The Device Master Record (DMR)

The Device Master Record (DMR)

The Device Master Record (DMR) is what may be described as the complete documentation required in the manufacture of medical devices that meet quality standards. The DMR, along with the Device History Record (DHR), is an extremely important element of the Quality System Regulation (QSR) in relation to FDA cGMP.

Inputs and final product

 The DMR constitutes the raw ingredients of the QSR. It is what goes into the QSR, while the DHR shows how these ingredients worked to deliver the final product. It needs to come with a Standard Operating Procedure (SOP), which defines the exact contents of the DMR, which will pave the way for the creation of an SOP for DHR, as well. One of the primary uses of a DMR is that being a master record; it tells employees the specific functions that need to be performed in the manufacture of a particular medical device.

No hard and fast rule about arrangement

Section 820.181 of the FDA spells out the requirements for DMR. A very important component of this section is that it does not make the type of arrangement of information about the device watertight. It gives sufficient freedom to manufacturers of medical device in that they are free to write information about it in any manner they like, so long as it is easily accessible.

Device specification –the core of the DMR

The foundation or what may be called the preface to the contents of the DMR is device specification. This section of the DMR briefly lists out all important details of the external nature of the device. Usually, a DMR device specification has the following:

o   the device's product trade and common name(s)

o   intended use(s)

o   environmental limitations and product stability

o   important components and formula (if applicable)

o   performance characteristics and theory of operation

o   physical characteristics

o   regulatory classification

o   user safety characteristics.
