It's a recommended best practice to include a review of certain incidents to identify lessons learned and any changes that need made to any piece of the "response" phase. This could involve procedures, training, equipment, staffing, or any of the myriad parts of an emergency.
The execution of these reviews can be as informal as the "back-step meeting" where the responding personnel gather at the rear of a fire truck and hash-out the sequence of events, what went right, and what could be improved. It can also be a days-later scripted meeting where a moderator leads all present through a series of standardized subjects and a formal written report is produced.
One of the more important maxims is to hold the event as soon as possible after the incident while details remain fresh in everyone's mind.
There is a recommended cycle that any level of post-incident analysis should follow in order to gain maximum benefit. The formal or informal findings for ways to improve are communicated to staff. Straightforward procedural changes are agreed upon and placed in draft form. This is followed by "practice" to work out any glitches or shortcomings in the proposed procedural change (or to declare it untenable and scrap the proposal). If the practice period results in a successful result, the draft is revised and then adopted into standard operating procedures or guidelines. This is followed by training of all personnel in the new procedures.
You can see how this process can be very simple or very complex. If it involves a change to medical protocol, our physician medical advisors need to weigh-in to assure it adheres to accepted medical practice. If it involves procurement of a new piece of equipment, there will be budgetary considerations as well as working through the actual purchase and procurement early in the review stage.
Worthington Fire & EMS prides itself on not settling for the status quo, and always being on the lookout for either refinement of existing best practices, or implementation of new and better ways of service delivery.
