Patients and methods: This population-based case–control study identified two groups from a nationwide claim database (National Health Insurance Research Database in Taiwan): a rural group and a non-rural group, which included 3,897 and 5,541 older people, respectively, who were hospitalized for accidental falls (The International Classification of Diseases, Ninth Revision, Clinical Modification: E880–E888) during 2006–2009. Both groups were followed up for 4 years after falls. Four-year cumulative all-cause mortality rate after falls was calculated, and the demographic factor, comorbidity, and medications were considered as the potential risk factors of mortality after falls. Results: The rural group had a significantly higher frequency of fall-related hospitalizations (7.4% vs 4.3%, P<0.001), but a lower 4-year cumulative all-cause mortality rate after falls than the non-rural group (8.8% vs 23.4%, P<0.001). After adjusting for age, gender, comorbidity, and medication use, the rural group had a significantly lower risk of mortality after falls than the non-rural group (adjusted odds ratio =0.32, 95% confidence interval =0.28–0.37, P<0.001). Age, gender, place of residence, comorbidity, number of medications, and inappropriate medication use were independent risk factors of mortality after falls. Conclusion: The rural older people had a higher frequency of fall-related hospitalizations but lower mortality after falls than the non-rural older people. Fall prevention programs should be adjusted for difference in place of residence.
