Key result
Non-traumatic SAH mortality in Colombia increases ~2% annually from 1999 to 2008.
Why the study?
Trends in mortality from non-traumatic subarachnoid hemorrhage in the Colombian population over time were not well characterized.
Observational (n=17,272)
Effect estimate: 1.6% increase per year (95% CI 1.0%-2.1%)
p-value: p=<0.001
May indicate rising SAH mortality burden in Colombia; hypothesis-generating and requires etiologic confirmation.
OBJECTIVE: To assess trends in mortality from 1999 to 2008 resulting from non-traumatic subarachnoid hemorrhage (SAH) in the Colombian population. METHOD: This population-based study analyzed all deaths by assuming a Poisson model. RESULTS: Subarachnoid hemorrhage-related deaths showed a statistically significant increase of 1.6% per year (p<0.001). The age-standardized analysis demonstrated an increased mortality trend of 3.3% per year (p<0.001) in people older than 70 years, but a decreased mortality trend in people younger than 50. It remained stable in patients 50-69 years old. CONCLUSION: The overall SAH-related mortality rate in Colombia has increased because increased mortality among the elderly has been counterbalanced by reduced mortality rates in younger age groups. These disparities may reflect epidemiologic transition, treatment inequities, or a less favorable comorbid profile.

Alcalá‐Cerra et al. (2013) conducted an observational in Non-traumatic subarachnoid hemorrhage (n=17,272). Calendar year (1999-2008) was evaluated on Trend in SAH-related mortality over time (1.6% increase per year, 95% CI 1.0%-2.1%, p=<0.001). The proportion of non-traumatic subarachnoid hemorrhage-related deaths in Colombia increased by 1.6% per year from 1999 to 2008.
