BestDose (formerly RightDose) is a Windows-based program that assists physicians and pharmacists in finding optimal doses for individual patients. Vancovanco bayesian calculator. Learning Objectives. Vancomycin regimens can be calculated both empirically (without any prior doses) or using one or two vancomycin levels. For single level dosing enter data under trough level below. Here we will implement Bayesian Linear Regression in Python to build a model. Historically, vancomycin in pediatric patients has been dosed at 40mg/kg/day for empiric Turner RB, Kojiro K, Shephard EA, et al. Vancomycin AUC/MIC was suggested as the preferred monitoring parameter for efficacy in the 2009 consensus review among American Society of Health-System Pharmacists (ASHP), the Infectious Diseases Society of America (IDSA), and the Society of Infectious Diseases Pharmacists (SIDP). 9. respectively. An accurate method of calculating the AUC is needed. Pharmacotherapy. Calculate . 2018;38(12):1174-1183. doi:10.1002/phar.2191 Appropriate dosing and administration of vancomycin requires consideration of the pathogen, type and severity of infection, patient weight, and kidney function []. Home-grown Microsoft Excel calculators, free online calculators with limited functionality, and paid advanced precision dosing software are all options. In patients with renal impairment, vancomycin trough will be ordered sooner than the 4th dose and subsequent While some of these resources may offer a solid starting point for dosing vancomycin patients, they are not capable of estimating AUC as individually and precisely as Bayesian modeling. And because vancomycin (somehow) distributes quite well into most tissues, we usually use a person’s total body weight to calculate this (rather than ideal or adjusted body weight). Area under the time–concentration curve (AUC) -guided dosing provides better estimates of exposure than vancomycin trough concentrations. Turner R, Kojiro K, Shephard E, et al. To calculate patient-specific V and K, at least two levels need to be drawn. Vancomycin Dosing Done Right. Bayesian forecasting was superior to a priori prediction, improving with the use of more recent concentrations. A Bayesian-derived 24-hour AUC/MIC BMD of 400 to 600 should be advocated as the target to achieve clinical efficacy while improving patient safety (assumes vancomycin MIC=1 mg/L). I actually would like to write a series of posts leading up to Bayesian Linear Regression. Vancomycin is a glycopeptide antibiotic that has activity against gram positive organisms including methicillin resistant Staphylococcus aureus (MRSA), and some Enterococcus species. In the most basic sense, here’s how Bayesian modeling works: 1. Using the Bayesian forecasting programs, individualized PK parameters were generated (using at least one serum vancomycin concentration) and AUC 0–∞ was estimated. In this webinar, we: Discuss the complexity of AUC dosing workflows and the benefits of Bayesian dosing for vancomycin. Thus, 1 - e- kel(τ) represents the fraction of the serum concentration that is eliminated. Bayesian forecasting is reported to improve trough concentration monitoring for dose adjustment. Please note this calculator will not work in patients with fluctuating renal function, on dialysis, extremes of weight, or inexplicably deviant kinetics. • In pharmacokinetic calculations, the term e-kel(τ) represents the fraction of the serum concentration that remains.

Antimicrobial Agents and Chemo 34; 550-554, 1990. Vancomycin is a concentration-independent killer of ... • Using Bayesian software limited the number of patients out of range in year 2 & 3 ... • More accurate estimate of AUC, but calculation has many steps and still requires 2 levels 32. Pharmacists will use a Bayesian calculator to calculate AUC and provide medical teams with guidance and dosing recommendations. Vancomycin is a glycopeptide antibiotic, typically used for treatment of MRSA. Traditionally it is recommended to get trough doses to assess efficiency. Typically, we aim for Vancomycin trough levels between 10-20µg/mL (15-20 µg/mL for more severe infections). Vance-Bryan K, Guay D, Gilliland S, Rodvold, K, Rotschafer J. When moving towards vancomycin dosing based on AUC:MIC, there are several tools for performing calculations. Healy DP, Sahai JV, Fuller SH, Polk RE. Recommendation: 1) Change vancomycin monitoring to AUC model. Data from 82 patients were used to evaluate 12 vancomycin models.

An alternative approach to the logarithmic trapezoidal rule is the use of Bayesian software programs to estimate vancomycin AUC 24h from a single serum concentration. Each of these terms refers to the same set of principles that helps clinical pharmacists take better care of their patients through dose optimization. Owner: DoseMe Pty Ltd. Last updated: Not found, however this is a new calculator so assume October 2018. You might hear different terms used to describe this concept: Bayesian dosing, Bayesian forecasting, Bayesian modeling, and model-informed precision dosing (MIPD), just to name a few. Vancomycin area under the concentration-time curve (AUC) has been linked to efficacy and safety. Pharmacotherapy. Dosing vancomycin in the super obese: less is more. Computer program for the initiation of vancomycin therapy. While not recommended by the guidelines, many institutions will "cap" a loading dose at approximately 2000 to 3000 mg. This calculator, when providing a loading dose, will cap at 3000 mg. A vancomycin loading dose cap of 3000 mg represents a maximum weight of 120 kg for a dose of 25 mg/kg. After we have trained our model, we will interpret the model parameters and use the model to make predictions.
