Incidence and risk factors of acute kidney injury after total joint arthroplasty; a retrospective cohort study
Hypothesis: To find the incidence and risk factors of acute kidney injury in arthroplasty patients. Risk factors which were assessed are: Age, obesity, gender, body mass index, smoking, COPD, type 2 diabetes, chronic kidney disease/renal dysfunction, hypertension, hypothyroidism, ace - i/A2RE, loop diuretics, thiazide diuretics, potassium diuretics, statin, beta blocker, prednisolone, volume of intra operative fluids administered, proton pump inhibitors and NSAIDs. The presence of AKI also was noted down for each patient. 1=yes/present 2=no/absent Data showed that age, obesity, smoking and COPD are risk factors of AKI. Surprisingly, hypertension and renal dysfunction were not among the risk factors. Data collection was done by manually retrieving patient information through electronic patient record (EPR).
