The toddler had been holidaying with his parents, Ben and Steph, in nearby Myrtleford, when he became unwell, vomiting, crying for hours and had a high fever.
He was earlier brought to an urgent care centre in the town after becoming severely lethargic and unable to keep fluids down.
A nurse at the Alpine Health facility noted symptoms of lethargy and being unable to keep fluids down before advising Noah be taken to hospital.
Dr Bumford, who was employed on a locum basis at hospitals across the state, clocked in more than an hour after Noah was admitted to the emergency department.
The toddler was discharged by Dr Bumford three hours after his admission, before he was brought back to the hospital by his parents hours later.
Dr Bumford “wholeheartedly accepted” meningitis and sepsis “should have been on my list, that was a huge error on my part”.
He also said not correctly picking up the symptoms was “in hindsight is terrible from me but that’s my honest answer”.
“Obviously there have been a lot of failings on my part,” he said.
“I put far too much weight on these observations when I should have looked at the bigger picture.”
Dr Bumford said Noah’s treatment and misdiagnosis constantly played on his mind.
“I’ve thought about (what I could have done differently) probably every day since it’s happened,” he said.
“A big problem for (the parents) was me not listening to them.
“I’ve thought about that a lot.”
Dr Bumford said he received no onboarding from the hospital except for providing immunisation history.
“Obviously everyone looked very busy. I had difficulty finding someone to direct me into the actual department,” he said.
“It seemed fairly chaotic and busy to me, but I didn’t really have any reference point (for what the hospital was usually like).”
Outside the Coroner’s Court on Monday, Noah’s parents remembered their son as a beautiful, gentle boy who loved cuddles and making others laugh and smile.
“We know our little boy would still be here today if all the medical services provided the expected level of care.”
A Northeast Health Wangaratta representative on Monday conceded the care provided to Noah was not appropriate during his first presentation and apologised to his family.
