Ketoacidosis as a consequence of diabetes mellitus (Type 1)
AI-generated summary
Steven Thelander, aged 29, died from ketoacidosis due to poorly controlled Type 1 diabetes while in residential disability support care at Multicap. He had cerebral palsy with severe intellectual impairment and epilepsy but was described as able to 'self-manage' his diabetes 'with supervision'—a characterisation that proved dangerously inaccurate. Critical failures included: lack of independent capacity assessment for diabetes management; insufficient clinical oversight by support workers who lacked understanding of diabetes pathophysiology; failure to escalate non-compliance with blood sugar monitoring despite recorded high readings (BSLs >20) and a low reading of 2; inadequate diabetes management plan from his GP; and no weekly meal planning despite dietary concerns. The trial sleepover revealed dangerous BSL variability but prompted no action. Escalation of warning signs in the final days was not acted upon. With appropriate clinical support, intervention, and escalation on 14 January would have offered ~95% survival chance.

Failure to escalate non-compliance with blood sugar monitoring despite clear warning signs
Trial sleepover (18–20 Sept 2017) showing dangerous BSL variability (readings of 24, 20, and 2) did not trigger placement review
Inadequate diabetes management plan from GP (Dr Brockman) dated 16 October 2017
Lack of weekly meal planning despite mother's dietary recommendations
Failure to escalate high BSL readings (>13.3 mmol/L) in final days despite supervisor and worker concerns
Missing clear emergency response protocols for hyperglycaemia
Lack of communication and escalation between support workers, supervisors, and managers
No attendance at dietician appointment (11 January 2018) by support worker
Absence of specialist endocrinology referral despite unstable diabetes control (HbA1c 8.9–9.1%)
Coroner's recommendations
Multicap should review promotional material to clarify specifically what services will and will not be provided, with detailed examples, particularly for 'high needs disability support'
Multicap should prepare a formal response plan or procedure for circumstances where a client lacks capacity but declines or refuses to comply with a care plan or regime necessary for life; the plan should detail appropriate responses for support workers, supervisors, and managers
