These are Alberta Health Services Guiding principles to a Just Culture.

• a standardised methodology including a common analysis language; and
• standardised analysis tools for reviewing clinical adverse events and close calls. 

There are three methodologies described within this handbook that can be used to review clinical Adverse Events. These methodologies are designed to suit the scope of a clinical adverse event or multiple clinical adverse events, and provide flexibility for the user.

• The Concise method is commonly used for a succinct review of close calls or clinical adverse events that result in no, low, or moderate harm to the patient or may focus on a new event for which a Comprehensive analysis was recently completed. The concise method is generally used for reviews conducted by one or two individuals.
• The Comprehensive method is used for a thorough review of a single clinical adverse event and involves a team approach.
• The Aggregate method involves a thorough review of multiple clinical adverse events and/or quality assurance reviews. This method is resource intensive and involves a team approach.
