Epidemiology of distal radius fractures in Germany - incidence rates and trends based on inpatient and outpatient data
Authors' conclusion
A relevant proportion of DRF were treated in outpatient settings, so both inpatient and outpatient data are necessary for a valid estimate.
Study context
- Population
- Persons aged ≥ 60 years insured by a large statutory health insurance in Germany, 2014–201817,705 distal radius fracture (DRF) events
- Participants
- 974,332 persons
- Outcome
- Incidence rates of distal radius fracture (DRF) events per 100,000 person-years (standardized) and time trends
Methodological detailsroutine statutory health insurance data, inpatient and outpatient data, age-sex standardization to the German population in 2018, Poisson regression
- Routine statutory health insurance data
- Inpatient and outpatient data
- Age-sex standardization to the German population in 2018
- Poisson regression
Main finding
As reported in the abstract
Standardized IR of DRF per 100,000 person-years [95% CI]
- Overall incidence rates (IR), 2014
- 439 [424-453]
- Inpatient IR, 2014
- 240 [230-251]
- Outpatient IR, 2014
- 199 [189-209]
- Overall IR, 2018
- 438 [423-452]
- Inpatient IR, 2018
- 238 [227-249]
- Outpatient IR, 2018
- 200 [190-210]
- Time trend, adjusted Poisson regression: IRR overall (no significant time trend)
- 0.994 [0.983-1.006]
Observational data: associations, not effects.
Further findings
DRF events hospitalized
- Hospitalized DRF events, of 17,705
- 9961 (56.3%)
Individuals with one or more DRF events
- Insured individuals with ≥1 DRF event
- 16,557
Factors associated with IR
- Female sex, older age, and comorbidity associated with higher IR
