  3. Obesitas Surgery –Mortality Risk Score (OS-MRS)

    Obesitas Surgery Mortality risk score: proposal for a clinically useful score to predict Mortality risk in patients undergoing gastric bypass.

    Http://www.ncbi.nlm.nih.gov/pubmed/17893494

    The OS-MRS assigns 1 point to each of 5 pre operative variables, including body mass index ≥50 kg/m2, male gender, hypertension, known risk factors for pulmonary embolism (previous thromboembolism, pre operative vena cava filter, hypo ventilation, pulmonary hypertension), and age ≥45 years. Patients with total score of 0 to 1 are classified as 'A' (lowest) risk group, score 2 to 3 as 'B' (intermediate) risk group, and score 4 to 5 as 'C' (high) risk group.

  4. Drug dosage formula need to come back!

    As of version 3.0.5, the following formulas were removed:

    Calvert
    Corticosteroids Converter
    NAC Dosing
    Opioid Converter
    Pediatric Resuscitation Doses
    Dose Calculator (was planned for future versions)

    Apparently they were forced by Apple to remove them to comply with the App Store policy...
    However, Epocrates and many other medical apps have drug dosage calculators. Why then should a great app like MedCalc not be allowed to have drug dose calculators?
    I don't know the details of why the formulas had to be removed, but vote if you want the formulas back!
