Summary
We conducted a study evaluating incidence rates and influencing factors in Romanian hip fracture patients. Our results showed that the type of fracture and its respective surgical procedure as well as hospital characteristics correlate with mortality. Updated incidences can result in updated treatment guidelines.
Purpose
The aim of our study was to assess incidence rates for a revision-calibration of the Romanian FRAX tool and to evaluate particularities of hip fracture cases to determine patient- and hospital-related variables affecting mortality.
Methods
We conducted a retrospective study using hospital reports of hip fracture codes to the National School of Statistics (NSS) from January 1, 2019, until December 31, 2019. The study population included 24,950 patients presenting to Romanian public hospitals in all 41 counties: ≥ the age of 40 with diagnostic ICD 10 codes: S72.0 femoral neck fracture, S72.1 pertrochanteric femoral fracture, and S72.2 subtrochanteric femoral fracture and procedure codes: O11104 (trochanteric/sub capital internal fixation), O12101 (hemiarthroplasty), O11808 (closed femoral reduction with internal fixation), O12103 (partial arthroplasty), O12104 (total arthroplasty). Hospital length of stay (LoS) was classified as follows: < 6, 6–9, 10–14, and ≥ 15 days.
Results
Incidence of hip fractures was 248/100,000 among those aged 50 + and 184/100,000 within the 40 + age category. Average age of the patients was 77 years (80 for females, 71 for males); 83.7% of the patients were 65 + with equivalent urban–rural distributions. Males had a 1.7 times higher mortality risk. Each year increase in age added a mortality risk of 6.9%. In-hospital mortality was 1.34 times higher among patients living in urban areas. Hemiarthroplasty and partial/total unilateral/bilateral arthroplasty had a lower risk of mortality than trochanteric/sub capital internal fixation (p < 0.02, p < 0.033).
Conclusion
Gender, age, residence, and procedure type had significant impact on mortality. Updated incidence rates will allow the revision of Romania’s FRAX model.
