In most cases, an audit of the quality management system by a notified body is a prerequisite for manufacturers of medical devices to be allowed to market their devices in Europe.

The FDA also audits quality management systems but refers to inspections rather than audits.

1. Basics for audits

a) Definition of the term

ISO 9000:2015 defines the term audit as follows:

systematic, independent and documented process for obtaining objective evidence and evaluating it objectively to determine the extent to which the audit criteria are fulfilled.

b) The different types of audits

Depending on the focus of an audit, there are:

  • System audits (e.g., inspection of the conformity of a quality management system with the requirements of a standard such as ISO 13485 or ISO 9001)
  • Process audits
  • Product audits
  • Software audits

A distinction is also made between

Please note!

System audits/audits of the QM system are the most important ones for medical device manufacturers. If successful, they will receive a certificate authorizing them to place their devices on the market in Europe.

Please also note the overview article on QM systems and the FAQ on QM systems and certifications.

c) Regulatory basis for audits

Europe

An audit by a notified body is the prerequisite for the notified body to issue a certificate (in accordance with ISO 13485 or Annex IX). This certificate in turn is the prerequisite for placing devices on the market, at least for products of higher risk classes.

Caution!

Manufacturers may only place their devices on the market on the basis of certificates from a notified body. There are other certification bodies whose ISO 13485 certificates are worthless. There are also providers who are not even accredited for ISO 13485.

USA

The FDA now also requires conformity with ISO 13485 but does not require certificates. It reviews conformity as part of FDA-inspections. However, unlike audits, inspections do not end with a certificate if they are successful.

Worldwide (“MDSAP countries”)

The International Medical Device Regulators Forum (IMDRF) has launched the Medical Device Single Audit Program MDSAP: An MDSAP audit can be used to fulfill the regulatory requirements for audits and inspections of QM systems.

2. Audit procedure

a) General

ISO 19011 describes the requirements for audits (i.e., their planning, implementation and documentation) and for auditors.

Further information

Further determinations specify the duration of audits.

If an auditor certifies a “non-conformity”, this can lead to the notified bodies refusing or withdrawing the certificate. In principle, what the auditor checks is known (see Fig. 1):

  • Auditors check whether the QM system with its specification documents covers all aspects of the standard, for example whether there is a Standard Operating Procedure (SOP) for internal audits that conforms to the standard.
  • Auditors check whether the organization has complied with the requirements of its own QM system i.e. SOPs.
During the audit, conformity with the company's own specifications and with normative and statutory requirements is checked

Fig. 1: Auditors check during the audit the conformity of the QM system with normative and legal requirements as well as the conformity with the company’s own QM system.

b) Special case of offsite audits

In a notice, the EU has regulated in more detail when and how notified bodies may carry out remote audits:

Calls for the possibility to take temporary extraordinary measures, including remote audits, related to notified body on-site audits under the medical devices Regulations have been made by industry as well as notified bodies.

The MDCG has published a Guidance on temporary extraordinary measures related to medical device Notified Body audits during COVID-19 quarantine orders and travel restrictions.

In it, it allows facilitations, e.g:

  • Delayed on-site surveillance audits
  • Replacement of audits with remote audits
  • Offsite inspection / review of technical documentation

Do you still have questions, for example about setting up your QM system? Then take advantage of our free micro-consulting service.

The consultants at the Johner Institute not only support you in setting up QM systems, but also audit these systems and prepare you for audits (e.g., with mock audits and mock inspections).

Understanding and avoiding deviations and nonconformities

Deviations, nonconformities, errors, findings, observations, and other terms are often used mistakenly synonymously. Even standards explicitly contradict each other when defining individual terms. This article clarifies, 1. Nonconformities: The basics 1.1 Definitions 1.1.1 Nonconformity ISO 9000:2015 defines nonconformity as “non-fulfilment of a requirement.” It equates this term with “error.” ISO 13485 contradicts this. This standard…

QM document control: How many fail audits

Document control is a documented procedure that specifies how documents are created, reviewed, approved, labeled, distributed, and updated. Organizations certified according to ISO 9001 or ISO 13485 are obliged to document control. 1. Subject matter of document control It is obvious that document control is about documents. What is less obvious is what documents are.…

DAkkS: What’s behind the outrage about ISO 13485?

The DAkkS, the German Accreditation Body, is Germany’s national accreditation authority. Recently, manufacturers, associations, and certification bodies have been raising their voices against the DAkkS. It is being vilified as an example of how German bureaucracy nips any innovation in the bud. What is the truth of these accusations? Are they justified? This article presents…

Remediation: When things hit the fan

“Remediation” is often synonymous with maximum stress: Notified bodies or authorities such as the FDA have discovered significant deviations that must be remedied with the highest priority and without regard to the workload of employees or budgets. This article will help you to complete such “remediation projects” in such a way that 1. Remediation: First…
