Time to hospital presentation following intracerebral haemorrhage: Proportion of patients presenting within eight hours and factors associated with delayed presentation

Abstract

PurposeProlonged time to diagnosis of primary intracerebral haemorrhage (ICH) can result in delays in obtaining appropriate blood pressure control, reversal of coagulopathy or surgical intervention in select cases. We sought to characterise the time to diagnosis in a cohort of patients with ICH and identify factors associated with delayed diagnosis. MethodologyThe stroke database of our hospital was retrospectively reviewed to identify patients presenting to our hospitals emergency department with ICH over two years (January 2017-December 2018.) Data collected included demographics (age and sex), comorbidities, anticoagulation status, clinical scores (NIHSS, GCS, ICH score), and imaging (anatomical site, haematoma size). Time from symptom onset to diagnosis and hospital presentation were recorded. Factors associated with diagnosis >8 h post ictus were assessed using a univariate and then multivariable analysis. Results235 patients were identified with 125 males (53%) and a median age of 76 (range 40-98). For the 200 patients that initially presented to our hospital, median time to presentation was 179 min (IQR 77-584 min), and median time from ictus to imaging diagnosis was 268 min (IQR 114-717 min). 139 (70%) presented within 8 h of symptom onset, and 129 (65%) patients had imaging of the brain performed within 8 h of symptom onset. Factors associated with presentation >8 h post symptom onset included wake up stroke (OR 5.31, 95% confidence interval (CI) 2.36-11.96, p < 0.0001) and age (OR 1.04, 95% CI 1.01-1.08, p = 0.01). Patients with hemiplegia were less likely to present >8 h following ictus (OR 0.41, 95% CI 0.21-0.84, p = 0.01). ConclusionsThe majority of patients with ICH presented within 8 h of ictus. Cases of delayed diagnosis involved patients who had not incurred hemiplegia.
