Hypothesis
The study aims to estimate the annual incidence and out-of-pocket medical expenses of all injuries in the urban population of Tehran.
Conclusion
The study found that the real incidence of non-fatal injuries in Tehran is significantly higher than hospital-based estimates, with substantial medical costs incurred by the population.
Supporting Evidence
- The annual incidence of all injuries was 188.7 per 1000 population.
- The mean out-of-pocket medical expense for injuries was 19.9 USD.
- Significant injuries needing medical care were reported at a rate of 68.8 per 1000 population.
- Fractures accounted for 19.3 per 1000 population.
- Children aged 15 or less had an annual incidence of 137.2 injuries per 1000.
Takeaway
Injuries that don't lead to death happen a lot in Tehran, and they cost people a lot of money for treatment.
Methodology
A household survey using cluster random sampling was conducted to gather data on injuries reported by residents over the past year.
Potential Biases
Potential recall bias exists, especially for minor injuries and those that occurred earlier in the study period.
Limitations
The study may have underestimated injuries associated with social stigma and relied on proxy informants, which could lead to underreporting.
Participant Demographics
The sample included 4,707 male and 4,393 female household members, with 1,465 children.
