EBMcalc assists with medical error detection and reduction.

When practicing, teaching, and learning medicine based on solid, literature-based data, practitioners may be overwhelmed by the breadth of information that they must master. EBMcalc helps simplify this task by assembling easy-to-use, interactive tools to support evidence-based medicine.

Using the Calculators

The Calculators tool is accessed via the blue tool bar at the top of the screen. Upon opening the tool, you are presented with an alphabetical list of the available calculators in the left panel. Select the desired calculation by searching for keywords in the "Calculator Lookup" box or by scrolling through the list of calculators displayed. The "Browse Category" drop-down menu can be used to browse a specific subset of calculators. The available categories include Adult, Conversions, Dental, Emergency Drugs, General, Infusions, International (SI Units), Pediatric, Pharmacokinetics, Renal Function Estimation, and Toxicology. Click on the desired calculator, and it will appear in the right content panel.

To perform a calculation, enter in the required variables. You can enter the value and then change the units, if necessary. Once all the inputs are entered, click the Calculate button to perform the calculation.

To help ensure patient safety, input data is checked against accepted values/ranges throughout the calculation process. When an input is restricted, click on the Input button to display the accepted range. If a value is entered that falls outside of the accepted range, a warning will be displayed after the Calculate button is clicked. This warning will be displayed in red text and will instruct the user to correct the value that is out of range before the calculation can be performed.

To start over, click the Reset button to clear all values and begin the calculation again.

To print a calculation, click the Print button in the upper right corner of the content panel and the printer options will be displayed.

To return to the main Lexicomp application, click on the Home button in the top left of the page.
