TmP/GFR
The Tubular PO4 Resorption (TRP) calculator would be enhanced tremendously by taking the arithmetic forward to the logical and clinically relevant conclusion: the tubular maximum resorption of phosphate, TmP/GFR. This would really benefit from an automatic calculation because TmP/GFR is calculated in two different ways depending on the TRP value.
1. When TRP is less than 0.86, TmP/GFR is simply TRP x serum phosphate.
2. When TRP is greater than 0.86, TmP/GFR is [serum phosphate][0.3TRP/(1-0.8TRP)A web calculator is here:

Brock Model
The British Thoracic Society have updated guidance on assessing solitary pulmonary nodules. They advise using the Brock model for predicting risk of malignancy following CT. This will now be standard practice for nodule follow up across the UK and would be a very useful addition to the app. The Herder model is currently on the app and is also recommended for use post PET-CT. Guidance and calculator reference available at www.brit-thoracic.org.uk

The 1800 rule for insulin sensitivity
A calc where you input current and desired blood sugar, total insulin and it tells you how much more insulin you need
Insulin sensitivity factor =1800/total insulin in day
To apply we do this calculation:
(Current blood sugar- target bs)/ insulin sensitivity factorA useful feature would also be to allow a range of 1500 to 2000 for the correction factor as a drop down menu, so I could choose the proper one according to the type of insulin
