Recovery from acute haemorrhagic leucoencephalitis secondary to COVID-19.

A man in his 50s presented with sudden onset expressive aphasia and right-sided facial droop after experiencing coryzal symptoms and malaise for 7 days prior to admission. A brain MRI showed a rapidly progressive mass effect across both hemispheres and cerebrospinal fluid analysis revealed neutrophil predominance with raised protein levels. Acute disseminated encephalomyelitis was provisionally diagnosed, and high-dose methylprednisone was initiated.On admission to the high dependency unit, the patient tested positive for COVID-19 and was treated with appropriate therapeutic agents for severe COVID-19. A subsequent brain biopsy confirmed a demyelinating process, strongly indicating a diagnosis of acute haemorrhagic leucoencephalitis when correlated with the presence of severe oedema on imaging. Nine sessions of plasma exchange were provided over 18 days.At the time of writing, the patient has made an excellent recovery. We urge clinicians to consider this diagnosis and these treatment options for an otherwise devastating condition.

Raise the Flag II: sepsis mortality before and after the introduction of a whole-of-system quality improvement programme at a tertiary hospital in New Zealand.

AIMS: To study in-patient mortality before and after the introduction of a whole-of-system sepsis quality improvement programme at a tertiary hospital in New Zealand. METHODS: The "Raise the Flag" sepsis quality improvement programme was launched in 2018. Discharge coding data were used to identify sepsis cases between May 2015 and July 2021. RESULTS: Of 4,268 cases of sepsis identified, 81% were over 55 years old, 34% were of Maori or Pacific Island ethnicity, 61% had significant co-morbid illness and over two thirds (68%) lived in the two highest quintiles of socio-economic deprivation. The adjusted odds of in-patient mortality were lower in the post-launch period (adjusted odds ratio [aOR] 0.83, 95% confidence interval [CI] 0.7-0.98, p<0.05), and were higher in association with age (aOR 1.04 for every additional year of age, 95% CI 1.03-1.05, p<0.01), socio-economic status (aOR 1.47 comparing the highest quintile of socio-economic deprivation with the lowest, 95% CI 1.06-2.04, p=0.02) and comorbidity (aOR 2.42 comparing a comorbidity score of 1 with a score of 0, 95% CI 2.1-3.52, p<0.01). CONCLUSION: In patients with a sepsis diagnosis, the odds of in-patient death were lower following the launch of the Raise the Flag sepsis quality improvement programme.
