Incidence and predictors of acute kidney injury after elective surgery for lumbar degenerative disease: A 13-year analysis of the US Nationwide Inpatient Sample – Lumbar Spinal Stenosis

The article investigates the incidence and risk factors of acute kidney injury (AKI) following elective surgeries for degenerative lumbar spine disease. The study utilizes data from the United States Nationwide Inpatient Sample (NIS) database and identifies ICD-9 and ICD-10 codes for lumbar degenerative disease, fusion, decompression, and AKI. The results show that the incidence of AKI after decompression or fusion is 1.1% and 1.8%, respectively, with an increasing trend in the United States. Underlying chronic kidney disease (CKD) was found to be the strongest predictor of AKI, significantly increasing the risk by 9.0- to 12.9-fold. Other predictors include older age, congestive heart failure, anemia, obesity, coagulopathy, and hospital-acquired infections, while long-term aspirin/anticoagulant usage was associated with a lower AKI risk. The findings of this study provide insights for risk stratification and treatment decisions after elective surgery for lumbar degenerative disease

CONCLUSION: Findings of this study inform risk stratification for AKI and may help to optimize treatment decisions and care planning after elective surgery for lumbar degenerative disease.

ABSTRACT

BACKGROUND: Acute kidney injury (AKI) is a severe postoperative complication associated with poor clinical outcomes, including the development of chronic kidney disease (CKD) and death. This study aimed to investigate the incidence and determinants of AKI following elective surgeries for degenerative lumbar spine disease.

METHODS: All patient data were extracted from the United States (US) Nationwide Inpatient Sample (NIS) database. After surgery, AKI’s incidence and risk factors were identified for lumbar degenerative disease. ICD-9 and ICD-10 codes defined lumbar spine degenerative disease, fusion, decompression, and AKI. The study cohort was categorized by type of surgery, i.e., decompression alone or spinal fusion. Regression analysis was used to identify associations between AKI and risk factors organized by surgery type.

RESULTS: The incidence of AKI after decompression or fusion was 1.1% and 1.8%, respectively. However, the incidence of AKI in the United States is rising. The strongest predictor of AKI was underlying CKD, which was associated with an 9.0- to 12.9-fold more significant risk of AKI than in subjects without comorbid CKD. In this setting, older age, congestive heart failure, anemia, obesity, coagulopathy and hospital-acquired infections were also strong predictors of AKI. In contrast, long-term aspirin/anticoagulant usage was associated with lowered AKI risk.

CONCLUSION: Findings of this study inform risk stratification for AKI and may help to optimize treatment decisions and care planning after elective surgery for lumbar degenerative disease.
