Improving NSAIDs Prescription in Emergency Services Unit by a Point-of-Care-Based Renal Function Evaluation

BACKGROUND: Patients evaluated in our emergency department (ED) often receive nonsteroidal anti-inflammatory drugs (NSAIDs) without any determination of their renal function, despite the known nephrotoxicity of NSAIDs. Guidelines recommend NSAID avoidance in patients with estimated glomerular filtration rate (eGFR) < 30 mL/min/1.73 m2, and long-lasting therapy is not recommended in people with chronic kidney disease.

OBJECTIVE: We aimed to highlight the influence of a rapid measurement of the eGFR on NSAID prescriptions in patients at risk of impaired renal function using a point-of-care (POC) device. Our goal was to prevent the potential nephrotoxicity of NSAIDs by allowing the physicians to modify their treatments after eGFR determination, while avoiding a standard blood test for patients that would extend the duration of stay in the ED.

METHODS: We included 192 patients evaluated in the ED for minor trauma or injury, with an indication of treatment with NSAIDs and no known contraindication to NSAIDs. Emergency physicians were asked to register their intention to actually prescribe NSAIDs based on their clinical gestalt with specific regard to kidney function. Immediately after, the creatinine level was measured in capillary blood and eGFR was calculated using the POC device (StatSensor Creatinine; Nova Biomedical, Waltham, MA). Our physicians avoided NSAID prescriptions when eGFR was < 30 mL/min/1.73 m2, and prescribed a shorter NSAID regimen therapy in patient with eGFR < 45 mL/min/1.73 m2, with a reminder to assure hydration. The decision based on eGFR was compared with original clinician intention.

RESULTS: The clinicians intended to treat 164 patients with NSAIDs (group 1) and defer NSAIDs in 28 patients (group 2). In the first group, eGFR results supported no change in intended NSAID use in 144 patients, highlighted the need for a short regimen in 17 patients, and indicated contraindication to NSAIDs in 3 patients. In group 2, eGFR determination allowed prescription of NSAIDs in 21 patients, allowed utilization of NSAIDs with a short course in 5 patients, and supported the clinician decision to avoid NSAIDs in 2 patients.

CONCLUSIONS: POC measurement of creatinine with eGFR estimation changed the prescription of NSAIDs in almost 25% of patients with previously unknown renal function.
