Inquest into the Death of Karl Albert STEINHAUSER

30y · Male·pulmonary thromboembolism in an overweight man with comorbidities (including recent hospital-acquired pneumonia) in the setting of receiving treatment for acute exacerbation of a psychotic disorder

Karl Steinhauser, a 30-year-old man with schizoaffective disorder and polysubstance misuse, died from pulmonary thromboembolism on 12 March 2023 while under Mental Health Act care. After two weeks of increasingly challenging management at Kalgoorlie Health Campus for acute psychotic exacerbation, he was transferred by RFDS to Fiona Stanley Hospital ICU, intubated due to severe agitation. He died post-extubation from massive PE. Key clinical lessons: (1) The referring unit lacked adequate psychiatric infrastructure, seclusion facilities, and ECT capability for managing acutely aggressive patients; (2) Family communication was minimal despite their knowledge of de-escalation strategies; (3) Extubation was delayed two days (10-11 March) due to security unavailability despite available mental health beds; (4) Earlier extubation might have reduced VTE risk but was not definitively preventable. No SAC1 investigation occurred at FSH, severely limiting root-cause analysis. While Karl's aggressive behaviour and medication side effects created treatment challenges, the underlying systemic limitations in regional mental health infrastructure and inter-hospital transfer coordination were critical contributing factors.
