BMI and body surface areaBody mass index from weight and height, with Mosteller body surface area alongside it — the number a chemotherapy or paediatric dose is worked from.Open the calculator →eGFR (CKD-EPI 2021)Estimated glomerular filtration rate from serum creatinine, using the race-free 2021 CKD-EPI equation, with the CKD stage the value alone supports.Open the calculator →Paediatric doseMilligrams per dose from the child’s weight and the mg/kg you are prescribing, with the adult ceiling applied and said out loud when it bites.Open the calculator →Corrected sodiumSodium corrected for hyperglycaemia, so a dilutional low reading in uncontrolled diabetes is not treated as true hyponatraemia.Open the calculator →Corrected calciumTotal calcium corrected for albumin, so a low albumin does not read as hypocalcaemia that is not there.Open the calculator →Due date and gestational ageExpected date of delivery from the last menstrual period, with today’s gestational age in weeks and days and the trimester it falls in.Open the calculator →

The documents a clinic needs

The other half of this page computes nothing: documents a clinic needs and cannot easily write, each one saying which lines MedAppz enforces for you, which it gives you the desk for, and which no software can do on your behalf. The useful half is open; the printable copy asks who you are.

DPDP Act 2023 — a clinic’s self-auditA list a clinic can work through in ten minutes, each line saying whether MedAppz enforces it for you, gives you the desk to do it, or cannot help at all. The score is worked out here in your browser and nothing you tick leaves it.29 lines, scored here →NABH readiness — what an assessor will ask forThe evidence questions that come up chapter by chapter, and where a hospital running MedAppz already has the answer as a row somebody wrote rather than a file somebody has to assemble.36 lines, scored here →Patient message templates that pass reviewThe appointment reminder, the payment reminder, the review ask and the recall — as MedAppz actually sends them, with the consent purpose each one rides and what the engine checks in the second before it goes.Open it →An IPD package price list that survives the argumentWhat a package price list has to say before it stops being disputed at discharge: what the price covers, how many days of it, and — the column everybody leaves out — what it does not cover.Open it →

Drip rate, oxygen cylinder duration, anion gap, MELD-Na and the scoring sheets live in CalcDeck, where a result can be saved onto the patient’s chart with its inputs preserved — which is the part a public page cannot do honestly.
