We’ve been working hard behind the scenes in preparation for American Pharmacists Month. To celebrate, we’re rolling out four new clinical tools and calculators on ClinCalc.com:
- Benzodiazepine Equivalence Calculator
- Enteral and Parenteral Nutrition Summary
- Number Needed to Treat
- Odds Ratio to Risk Ratio Conversion
Benzodiazepine Equivalence Calculator (link)
There is a serious need for higher quality, evidence-based benzodiazepine online conversion tools. After scouring through numerous articles and medical textbooks, we’ve created the most comprehensive benzodiazepine conversion calculator online. This calculator includes many benzodiazepines that are not included in other conversion charts and tables (such as midazolam) and provides a confidence range during the conversion process when there is a discrepancy in the literature regarding the most appropriate equipotent benzodiazepine dose.
Enteral and Parenteral Nutrition Summary (link)
We’ve received some very positive feedback regarding our Enteral Nutrition Calculator and our Parentral Nutrition Calculator. These calculators are valuable resources when initiating a new nutritional regimen, but we found that many clinicians wanted to analyze an existing regimen. In response, we’ve created a new Enteral and Parenteral Nutrition Summary calculator. Using this tool, clinicians can quickly calculate and evaluate a patient’s daily protein intake, caloric intake, and macronutrient breakdown.
Number Needed to Treat (link)
In order to promote our evidence-based medicine mission, we’ve created a number needed to treat (NNT) calculator to help clinicians summarize the benefit (or harm) for a given treatment. Unlike most other calculators available online, we’ve incorporated “event rate” NNT in which a study endpoint is described in person-time (such as 24 events per 1000 patient-years).
Odds Ratio to Risk Ratio Conversion (link)
As our final calculator to celebrate American Pharmacists Month, we’ve created a tool to convert an odds ratio (usually from logistic regression analysis) to a risk ratio. When examining a study using logistic regression, an odds ratio will exaggerate a treatment effect if the incidence rate of the outcome is common (eg, more than 10%). To correctly interpret an odds ratio to determine the risk or benefit of a treatment, it should be converted to a risk ratio.
