The problem is: NEF packs its bags when

• only an Ambulance (KTW or RTW) is needed
  
• a NAW or RTH arrives.
  

This is the right way in Germany, so I think it will stay so.
But the FR reaction may be discussable
For now You can only click "verstanden", not "verstanden, zur Wache". Then the Units will stay at the scene until You sending them home by clicking "H"

Jetzt darf erstmal über mein "Englisch" gelacht werden, macht es doch bitte jemand besser

It's not. @Bass D. is describing a system which can be found in Europe as well. Units being on scene will normally stay as backup as long as they're not dismissed. Even if a medic is not required he/she will have a (brief) look at the patient if the unit has arrived anyway and is not needed anywhere else.

This problem is caused by the way the game works. The patient starts at a certain health level. Lower scores have to be treated by advanced paramedics up to a doctor. As soon as the required team starts treatment the game calls the basic units off because they're not needed anymore. Any kind of support can not be displayed by now, just "able to raise health up to 100 %: yes or no". Unfortunately the programmer might not change this in the near future (or at all) because it's not that easy to implement. But the majority sholud be with your opinion, it has already been discussed a couple of times.

The best way to simulate all units staying on scene is to play like @marcee wrote: Just answer "10-4" ("Verstanden.") to "We're not needed anymore."/"Patient handed over." and keep them in standby (status 1). As soon as the patient is ready for transport send everyone home ("H" when unit is selected or left click on unit -> "Status" -> "Zur Wache").


@marcee: Passt schon, ist soweit verständlich.

@marcee said "Germany"
@coswiger said "Europe". As well it can be found in Europe, but the right way in Germany ist The way from @marcee.

Where I work in Germany, First Responder stays on scene til the patient is in the ambulance.
Same for the NEF. Even if there is no need of the notarzt they will stay for a while to check the patient and document it.
It is rare that NEF or FR drive away as soon as the ambulance arrives

Of course, in this cases they could stay a little bit longer, but not necessary until the ambulance starts the way to the hospital. This could take a lot of time in Germany
And You see: It´s different within Germany. In some areas are lots of NEF, in other there is only one NEF for 150.000 people...

NEF stays til Transport begins, that's The way in every Single region I've worked in or seen. Some go to Status 1 ASAP when not needed, others stay in Status 4 until it's time to leave The scene.

P.S. I hate Auto correcture on my cell. But it s funny to see what it does with english when it thinks I writing very bad in German.

@eifeler: So GER is not part of EU for you? I have not excluded us because what @marcee and you said is not the "normal" way, at least not these instant standby and going home right away situations the game uses everytime. There is no "the right way in Germany". On scene the unit in command dismisses the assisting ones, not the dispatcher. Even while staying on scene a FR or NEF can be redispatched if needed.

Germany is a part of Europe, but @marcee talked from Germany. Only Germany. And I think Germany isn't the complete EU. And you, @coswiger, talked from Europe.
And the way which marcee described is the way which I know too. So, for me it's the right way in Germany. But that isn't right. In Germany there are these ways which were described by marcee and TheOssi.
