4.4 Relevant definitions in the risk management process

 

Harm

Damage to health of recipient, including the damage that can occur from loss of product quality or availability (loss of tissue, damage for the donor)

Hazard

The potential source of harm

Risk assessment

contains risk identification, risk analysis and risk evaluation.

Risk analysis

The estimation of the risk associated with the identified hazards

Risk evaluation

The comparison of the estimated risk to given risk criteria, using a quantative or qualitative scale, to determine the significance of the risk

Risk control

contains risk reduction or risk acceptance

Risk review

contains an evaluation or review after a period of time to assess the measures taken and define if the identified risks are reduced effectiveley

 

Based upon the 3 principles of risk management, the definition of risk management could be stated as follows:

 

‘Risk management is the overall quality management process by which risks are identified, evaluated, controlled, monitored and reviewed.’

Severity = the degree of harm

Probability/occurrence/possibility = the likely rate of occurrence

 

Risk = severity x probability (x detectability)

Figure 2 presents a schematic overview of all steps taken in a typical risk management process. The tools for risk management and the communication on the risk management process are important factors in the risk management process and are therefore drawn on the sides of the process, to underline their mutual dependency.
