Abstract

Summary

The 30-day mortality of osteoporotic hip fracture patients ≥ 50 years at Hawai’i Pacific Health (2015–2016) was 4.2%. Mortality increased to 17.1% (1 year), 24.5% (2 years), and 30.1% (3 years). Increased age, male sex, higher CCI score, primary insurance status-Medicare/Medicaid, and lower BMI were associated with increased mortality.

Purpose

The objective of this study was to evaluate mortality and factors associated with mortality of osteoporotic hip fracture patients at community hospitals within a large healthcare system in Hawai’i.

Methods

A retrospective chart review was conducted of 428 patients, ≥ 50 years, and hospitalized for a osteoporotic hip fracture from January 2015 to May 2016 within a large healthcare system in Hawai’i. Patient demographics, comorbidities, and treatment were collected from retrospective chart review. We determined the date of death by review of medical records and online public obituary records. We calculated 30-day, 90-day, 1-year, 2-year, and 3-year mortality after discharge for hip fracture admission. Multivariable logistic regression and proportional hazards regression were used to evaluate associations between variables and the mortality of the patients.

Results

The 30-day and 90-day mortality after admission for hip fracture were 4.2% and 8.6%. One-year mortality, 2-year mortality, and 3-year mortality were 17.1%, 24.5%, and 30.1%, respectively. Through proportional hazards regression, older age (hazard ratio (HR) = 1.06, p < 0.001), high comorbidity load (HR = 1.30, p < 0.001), and primary insurance status-Medicare/Medicaid (HR = 3.78, p = 0.021) were associated with increased mortality, while female sex (HR = 0.54, p < 0.001) and higher BMI (HR = 0.94, p = 0.002) were associated with lower mortality.

Conclusion

After admission for osteoporotic hip fracture, the 30-day mortality was 4.2%. At 1 year, 2 years, and 3 years, mortality increased to 17.1%, 24.5%, and 30.1%, respectively. Increased age, male sex, higher Charlson comorbidity index score, primary insurance status-Medicare/Medicaid, and lower body mass index were associated with increased mortality.
