Introduction: Globally, traumatic brain injury (TBI) is the foremost cause of death and disability in both children and young adults (Lancet Neurology, 2010). Despite the high total incidence in New Zealand (790/100,000) (Feign et al. 2013), little is known about TBI in the inpatient setting and patient pathways following hospital discharge.
Aims: To investigate the volume, injury characteristics, resource allocation and patient journey of Midland residents hospitalised with a TBI.
Methods: A retrospective review of Midland Trauma Registry data between January 1, 2012 and December 31, 2019 was conducted. Eligible patients (N=4875) were Midland residents hospitalised with an injury to the brain parenchyma.
Results: An average 609 Midland residents were hospitalised with a TBI diagnosis per year, increasing 152% from 479 in 2012 to 727 in 2019. Concomitant injuries occurred in 78.1% of TBI patients. TBI diagnoses explained 66.1% of total Injury Severity Scale scores. Of all patients, 72.1% had TBI AIS severity scores of 1-2 (mild-moderate). The remaining 1364 patients (171 per year) had TBI AIS severity scores ≥3 (serious, severe, critical and maximum). Brain surgery was required by 3.5% of patients, 25.5% received other surgery, 14.9% were admitted to intensive care and 3.7% died as a results of their injuries (TBI or other). Mean length of hospital stay for TBI patients was 5.8±9.3 days. Across the hospital journey, 468 transfers to out-of-region facilities for acute-care and/or rehabilitation occurred for Midland domiciled TBI patients, an average of 59 transfers each year.
Conclusion: TBI resulting in hospitalisation in Midland residents are prevalent, diverse and complex demanding important hospital resource utilisation. The number of out-of-region transfer rates signify challenges along acute-care and rehabilitation pathways.
