MedicalResearch.com: What are the main findings of the study?

Answer: This study examined the incidence, causes and outcomes of rhabdomyolysis in two large University Teaching hospitals. Rhabdomyolysis is a characterized by an increase in serum creatine phosphokinase (CPK) and results from muscle damage from a variety of causes. The most important complication of rhabdomyolysis is acute kidney injury which can result in a need for dialysis. Using a series of laboratory and clinical variables that are readily available on admission, we constructed a risk score that can predict with some accuracy the likelihood that a patient with rhabdomyolysis might die or need dialysis during an admission. The final variables included in the model were age, gender, the cause of rhabdomyolysis and the admission CPK, creatinine, phosphate, bicarbonate and calcium. One of the advantages of this study was, because we had access to data from two institutions, we were able to derive the risk score in one hospital and confirm its accuracy in the second institution.
