Required data were gathered using census method via a checklist consisting of demographic data, cause of the accident, length of hospital stay, number of times revisiting the hospital, and final outcome. Data were then descriptively analyzed using SPSS 16 statistical software.

The most common causes of accidents were falling with 1033 (44.2%) cases, intentional poisoning with 382 (16.4%) cases, and unintentional poisoning with 360 (15.4%) cases, respectively. Mean length of hospital stay was 5 ± 7.7 days. 144 (6.2%) elderly patients died during the study period. Type of accident (p < 0.001) and final outcome (p < 0.001) were significantly different between the sexes.

Conclusion: Based on the findings of the present study, falling, intentional poisoning and unintentional poisoning, respectively, were the most common causes of preventable accidents in the studied elderly population. Most cases were discharged after partial recovery and the 3 afore-mentioned causes had higher prevalence in women.
