Outcome Measures

Primary Outcomes (1)

  • To validate the use of APTT CWA and ICIS, as early sepsis markers for neurosurgical ICU patients suffering subarachnoid haemorrhage, traumatic brain injury and other intracranial haemorrhages.

    Activated Partial Thromboplastin Time (APTT) clot waveform analysis (CWA) by flow cytometry-based method

    SICU stay from day 1 to day 5 through to 2 years of blood test completion

Secondary Outcomes (1)

  • To examine the evolution of CWA, immuno-parameters (KL-6, SP-A, MIG, presepsin) and various WBC activation markers over the time in relation to diagnosis of sepsis, development of positive blood cultures and mortality or recovery.

    SICU stay from day 1 to day 5 through to 2 years of blood test completion

Study Arms (1)

SICU cohort

150 subjects with the admission diagnosis of neurological haemorrhage (e.g. subarachnoid haemorrhage, intracerebral haemorrhage etc), admitted to SICU of National University Hospital, Singapore, who are expected to stay for more than 48 hours, will be recruited and enrolled. Frequency of blood sampling will be stipulated atday 1/2/3/4/5 to draw clinical relevance. An additional 0.5 tablespoonful (7.7ml) of blood will be taken daily from each subject as well as residual blood from routine laboratory test blood samples.

Diagnostic Test: APTT CWA (Activated partial thromboplastin time clot waveform analysis), Procalcitonin and Serological/Inflammatory markers (KL-6, SPA, MIG, Presepsin)

Interventions

Primary Aim: To validate the use of APTT CWA (Activated partial thromboplastin time clot waveform analysis) and ICIS (Intensive Care Infection Score), as early sepsis markers for neurosurgical ICU patients suffering subarachnoid haemorrhage, traumatic brain injury and other intracranial haemorrhages. Secondary Aim: To examine the evolution of CWA, immuno-parameters (KL-6, SP-A, MIG, presepsin) and various WBC (white blood cell count) activation markers over the time in relation to diagnosis of sepsis, development of positive blood cultures and mortality or recovery. Blood parameter measurements using a 3-part and 5-part differential analyser will be performed. KL-6, SP-A, MIG, presepsin are serum biomarkers - MIG (Monokine induced by gamma interferon), SP-A (Surfactant protein A), KL-6 (Krebs von den Lungen 6).
