Judgement call

Was on night shift. During handover there was a call for an ambulance. It was a burn case, which seemed to be simple. I thought it might just be pain management and minor wound treatment or just a patient transfer to the burn center. I made a judgement call to just send the night standby doc and consider it as an urgent call out. I was quite surprise to see a patient with a full thickness burn on the face and hands. It turns out it was a blast injury from a barbeque. I was reluctant to move the patient to the ER, but since it was another doctors patient I just followed and support. The plastic surgeon was called and he said this can be treated in our hospital. I still felt uneasy. Especially when I just realized the nursing care is really complicated. We had limited resource and experience. I tried to have the patient referred but the surgeon disagrees. I just feel I did a bad initial judgement call. 
A lesson I learn from this: Do not underestimate a call for an ambulance, even if it seems a simple case, it's better we overestimate fir he worst first. Also I should use my authority more to interfere when really necessary. I always do not want to interfere with my colleagues, but maybe once and a while I should if it may affect the patient's outcome.
