Acute renal failure (ARF) in hospitalized patients is a common diagnosed condition. Epidemiologic studies of hospitalized patients have suggested a frequency of almost 20 cases per 1,000 hospitalizations. While most patients with acute kidney injury (AKI) recover renal function, as manifested by improvement in urine output and a decrease in BUN and serum creatinine, many, including those with previously normal kidney function, never recover to their previous baseline level of function.
In addition, many studies have demonstrated an increase in the risk of chronic kidney disease (CKD) and end-stage renal disease (ESRD) among patients who recover from AKI. While patients with significant increases in creatinine predictably have much higher mortality rates, even more modest elevations in creatinine (as little as 0.5 mg/dL) have been found to be associated with a significant increase in mortality and a >3 day increase in length of stay (LOS). As AKI impacts significantly on morbidity, mortality, and LOS, and is present across a broad spectrum of clinical presentations, it follows that AKI is significantly more expensive to care for hospitalized patients with acute kidney disease.
The ability to correctly identify, document, and accurately code for the presence of acute kidney disease has a major impact on the ability to capture revenue that appropriately reflects the outlay of hospital materials and resources required in the proper care of these patients. Better understanding the physiology, terminology, and clinical findings that define acute renal failure will help standardize the query process, and ultimately improve the hospital's ability to reliably capture the diagnosis.
Why This is Relevant:
Diagnosis and accurate documentation of the various etiologies of acute and chronic kidney disease in hospitalized patients can have a critical impact on treatment, hospital length of stay, and long-term patient outcomes. Additionally, accurate coding of kidney disease can have a measurable impact on reimbursement.
