Advance Directives
What Paramedics Can And Cannot Act On
Ambulance crews work to protocols that require specific, recognised documentation, which is why a well-written directive at home may not change what happens in the driveway.

Emergency crews operate under rules that differ from those in a hospital ward. Understanding what they are permitted to accept explains many outcomes families find inexplicable afterwards.
Protocol replaces deliberation in an emergency
A crew arriving at a collapse has minutes and no clinical history. Their protocols default to resuscitation and transport, because acting is reversible in a way that not acting is not.
Reading and interpreting a lengthy legal document at the scene is not realistic, and in many services crews are not authorised to make that interpretation on their own.
The result is that a directive written in careful prose may have no practical effect during the very episode it was intended to govern, however valid it is.
Recognised forms exist for this reason
Many health systems have developed short standardised forms, usually signed by a clinician, that record resuscitation and treatment decisions in a format ambulance crews are authorised to follow.
These sit alongside a personal directive rather than replacing it. The directive expresses the wishes; the clinical form translates them into an instruction the service can act on.
The names and formats vary widely between countries and even between regions, so the practical step is asking a family doctor which document applies locally.
Visibility at the scene decides the outcome
Crews are trained to look in a small number of predictable places. A form on the fridge, in a folder by the front door or with the patient's medication is likely to be found.
A document in a bedroom filing cabinet or a safe deposit box will not be. Neither will one that only exists on a solicitor's file or in an email attachment.
Some services use a register or an alert flag against an address, so a call to that address arrives with the information already attached to the dispatch.
Doubt resolves in favour of treatment
Where a form is unsigned, undated, contradicted by someone present, or simply unclear, the crew will generally treat. That is the correct response to genuine uncertainty.
Relatives who object at the scene create exactly this doubt, which is why the family conversation matters as much as the paperwork does.
Once treatment has begun, decisions to withdraw it move to the hospital, where there is time to locate documents and involve senior clinicians.
Making the two documents work together
The practical arrangement is a personal directive setting out reasoning and values, a recognised clinical form for the emergency, and a family who know both exist.
Rules on what ambulance services may accept vary by jurisdiction and change over time. This is a general description, and a doctor should advise on the specific forms used locally.
