Trough Calculators

Trough drawn early? -Estimation Tool based on entered Kel
——— This new program can be used to determine when to administer the next dose of vancomycin after a supratherapeutic trough is obtained. An estimated elimination rate constant is generated from the creatinine clearance which is then used to determine the timing of the next dose based on the desired target trough concentration.Vancomycin -Timing of next dose based on estimated Ke value
——— Use this program if the vancomcyin level is drawn early and you want to estimate the actual trough just before the next dose to determine if the current regimen is appropriate Vancomycin – Predicted Trough-Level drawn early

Vancomycin – Single-level dosing

Vancomycin SINGLE Level-(dosing by levels) Original calc ledIf you would like to enter the time since the last dose was given, use this version.This new version may be especially useful if the trough was drawn late and thenext dose was delayed. Example: current regimen vanco 1 gram q12h. Trough wasdrawn 12.5 hours after the last dose.Vancomycin single-level – dose infused early or lateThe GlobalRPh vancomycin single-level calculator uses the Vd recommended in Bauer’s text: 0.7 L/kg. Use the advanced version if you wish to manipulate this value.Vancomycin single level – Advanced version

  1. International Prostate Symptom Score (IPSS): consists of 8 questions (the original American Urological Association symptom score (AUA-7)) plus one additional quality of life question.
  2. Urinary Incontinence Treatment /Symptom Calculator
  3. Overactive Bladder Symptom Score (OABSS): a reliable, valid and highly responsive tool to fluctuations in overactive bladder symptoms.
  4. International Index of Erectile Function (IIEF) (also known as the SHIM Questionnaire).
  5. Overactive Bladder 8-question Screener – (OAB-q).
  6. ADAM (Androgen Deficiency in Aging Males) questionnaire consists of 10 questions that help determine if a male patient suffers from androgen deficiency.
  7. Aging Males’ Symptom (AMS) scale allows for a more quantitative assessment of testosterone deficiency (TD) compared to the ADAM score.
  8. Gender-Specific: Estimate 24-Hour Urine Protein from Protein to Creatinine Ratio
  9. Urinary Indices
