The health watchdog says Wellington's Capital and Coast health board has made an important change in the wake of a case which left a baby blind, deaf and brain damaged.
Health and Disability Commissioner Anthony Hill faulted the DHB in a major report this week over the care given to three month-old William Burton, who two doctors failed to diagnose with meningitis in 2013.
Mr Hill said the situation facing Wellington Hospital was complex and difficult.
But he added that changes made by the DHB since, boosting oversight by senior doctors, were needed and are pleasing.
"Capital Coast have changed their protocols and it is now a mandatory requirement that an unplanned representation within 72 hours will automatically attract review by a senior doctor. That's an important change and it's an important safety correction."
