The 3x Labour calls that require a community midwife are
Labour - Waters Broken
Labour - Premature Birth
Labour - Home Birth
and their unit requirements are kinda high.
Labour - Water Broken - Surely this call would either require CMs and would become the standard home birth version, not necessarily requiring an ambulance at all, or it would be a transport job to the hospital for delivery there, at which point I can maybe see 1x CM and 1x Ambo, but I cant see why you would need 2+2.
Labour - Premature Birth - I can see this call being more resource intensive, but im not entirely sure why 2x Ambulances would be required though. 1 yes, to transport the patient, as well as something to handle the CC requirements. but 2x DCAs and something for CC.
Labour - Home Birth - Would 2x CM vehicles be required?
Overall, I do think a core part of this change could be changing the CMs requirement to be personnel rather than vehicles, which would help streamline the calls a little, as they feel kinda resource intensive and require a lot of CMs to be deployed within a setup, but the ambulance requirements seem a little high on at least the water broken call.
There is also the Child Birth that has no CM requirements, not even a chance of needing of them, and only a 30% transport chance? Just seems maybe a little low?
