"Observations did not trigger the escalation in care that should have occurred," the commissioner reported, adding documentation was poor.
"These factors hindered the co-ordination and delivery of care," Hill said. "While individual staff held some responsibility for their failings, overall the deficiencies indicated a pattern of poor care across services."
He considered that DHBs are responsible for the operation of the clinical services they provide and can be held responsible for any service failures, that "they have a responsibility for the actions of their staff and an organisational duty to facilitate continuity of care.
"This includes providing adequate support to its staff in respect of the application of relevant policies, and ensuring that staff work together and communicate effectively."
He recommended the apology and an audit of services to ensure the standard clinical tool was used to transfer consumer information between the Emergency Department and the Acute Admissions Unit.
He also recommended the DHB audit its compliance with the Early Warning System Policy in both the Emergency Department and the Acute Admissions Unit, and asked the DHB to provide evidence that better education would be provided for junior doctors about how and when to contact an on-call consultant, and that a dedicated surgical registrar would be available at night time.
