Background

Information on CKD patients with hip fractures (HF) regarding morbidity, mortality and osteoporotic treatment is scarce.

Aim

We aimed to explore the prevalence, clinical characteristics, pre-fracture anti-osteoporotic treatment and hospital outcomes in CKD patients experiencing HF.

Methods

In 3623 consecutive HF patients aged≥65 years (mean age 83.4±7.50 [SD] years; 74.4% females), prospectively collected clinical data were analysed. CKD was defined as estimated glomerular filtration rate (eGFR)<60 ml/min/1.73m2.

Results

In our HF cohort, 1444 (39.9%) patients had CKD, of whom stage 3a comprised 716 (49.6%), stage 3b – 465 (32.2%), stage 4 – 217 (15.0%) and stage 5 – 46 (3.2%). Among HF patients CKD prevalence was 9.5 times higher than in the general population aged≥75 years (43.6% vs. 4.6%). CKD patients compared to the non-CKD were older (+4.1 years), had a greater prevalence of hypertension (62.1% vs. 52.6%), anaemia (51.3% vs. 36.3%), coronary artery disease (36.9% vs. 24.7%), history of myocardial infarction (10.3%  vs. 6.3%), atrial fibrillation (23.1% vs. 16.9%), type 2 diabetes mellitus (17.1% vs. 10.7%) and dementia (33.1% vs. 29.3%), as well as significantly higher mortality rate (8.2% vs. 3.3%, p<0.001) and prolonged admission (LOS>10 days: 60.3% vs. 54.2%, p=0.04). Of 189 HF patients who died 118 (62.4%) had CKD. CKD increased mortality risk by 180% (OR 2.8; 95%CI 2.06 – 3.76) and LOS>10 days by 30%; the effects were strongest for stage 5 (ORs 4.6 and 2.5, respectively). A 1ml/min/1.73m2 decrease in eGFR increased mortality risk 3%. Only 10.2% of CKD patients received osteoporotic drugs (bisphosphonates, denosumab) pre-HF.

Conclusions

Among HF patients, CKD is highly prevalent contributing to excess morbidity, mortality and prolonged LOS, but rarely treated for osteoporosis.
