MOI and History of Chief complaint

[ParkerFire]

I understand in theory what MOI and History of Chief complaint are but could someone give me a few examples of each in a senario setting? For instance, in an MVA are you saying the vehicle hitting the post is the MOI or are we saying the steering wheel hitting the patient in the chest is the MOI? And then, say the patient's chief complaint is pain in the leg due to a ankle fracture. In getting the history of the chief complaint, are we just asking how it happened basically and doing the PQRST or is there more involved? Any help would be appreciated.

For your MVA scenario, there are a few things happening, 1. You have the car hitting the post, 2. You have the driver hitting the steering wheel (guessing no air bag), 3. You have the internal organs hitting the rib cage. I am guessing the MOI is the Method of Involvement or Incident?.

Chief Complaint is the main reason why you were called by the patient. Once you find out what is going on, then you get the history behind the Chief Complaint. Be it SOB, Chest Pain, etc. Even though there could be something else going on. My wife is a dispatcher for the RCMP and they now listen to all calls for BCAS as more and more drug addicts are getting smarter when there is an overdoes, they are calling for chest pain or sob, RCMP used to not listen as it was something that they didnt need to attend to, then once BCAS gets on scene they discover its actually an overdose, so ambulance had to contact RCMP and they have to attend.


Hope that helps a little

The Mechanism Of Injury is how and/or what caused the injury.

IE:20 y/o driver of a small car single occupant, struck concrete pole at a high rate of speed significant damage to the car and pole.Pt struck steering wheel no airbag deployed then into primary assessment ABCs chest sounds and movement,physical findings and secondary assesment.

The ankle question is How it happened, circulation/nerve involvement physical findings.

PQRST is more for tracking down a medical complaint.

MOI generally refers to an incident involving some sort of trauma. The Hx of the C/C is in most cases essentially the MOI.

If you are talking about the Hx of C/C in more of a medical call context then it would be different (i.e. onset of substernal chest pressure this afternoon while walking etc.)

I am guessing you are studying for FR exams. They have some really good handouts on critical history for different types of incidents at the Paramedic Academy. If you can get your hands on those it may be helpful.

The easiest way to study is to get your hands on a copy of an FR report which pretty much lays out the entire assessment model on paper in front of you.

Most exams at the Paramedic Academy have around 50% of the marks weighted in the first 5-10 min of the exam. They are really looking for good primary survey and critical interventions like we were talking about on the FR thread.

Think of the MOI as what force was applied to the body and how was it applied.
