Traumatic brain injury remains one of the most under-documented catastrophes in lower-income countries, where lack of neurosurgical infrastructure, ICU capacity, and rehabilitation services can turn survivable injuries into death sentences. New longitudinal data from Pakistan now provide the first systematic picture of what happens to these patients over a full year — and the figures are stark enough to reframe how the global health community should prioritize TBI funding and intervention.
Drawing on a prospective multicenter trauma registry across two tertiary hospitals in Karachi, researchers tracked 819 adult TBI patients between December 2021 and May 2024, categorizing them by Glasgow Coma Scale score into moderate (GCS 9–12) and severe (GCS ≤8 or intubated) groups. Inpatient mortality reached 22.9% for moderate TBI and a devastating 68.9% for severe TBI. Road traffic crashes accounted for nearly three-quarters of all cases (74.1%), and the cohort skewed heavily male (84.1%) with a median age of 38 years. Follow-up data at 1, 3, 6, and 12 months also captured quality-of-life trajectories for survivors, with 19.3% of patients lost to follow-up by year's end — itself a meaningful data point about post-discharge vulnerability.
These mortality rates are substantially higher than those reported from high-income country trauma systems, where severe TBI inpatient fatality typically ranges from 30–50% even in comparable severity bands, reflecting differences in CT availability, neurocritical care staffing, and intracranial pressure monitoring. The finding that road traffic crashes dominate the injury mechanism is consistent with WHO projections placing road injury as a leading cause of death in South Asia, and underscores that TBI burden in LMICs is not simply a medical problem but an infrastructure and urban-planning crisis. A key limitation is that tertiary-center enrollment likely captures more severe presentations, potentially inflating mortality estimates relative to the broader population. Single-country data also limits generalizability across LMICs. Nonetheless, as the first study from this region to report long-term QOL alongside mortality, this work is a meaningful baseline — incremental in scope but potentially catalytic for regional trauma policy.
