How Calculator Tools Work

Pharmily+

Every calculator in Clinical Support Tools is built on the same shell, so once you've used one, you know the layout of all 17.

Layout

• Breadcrumb at the top — Clinical Support Tools → the tool's name — with a back arrow to return to the index.
• Header — the tool's name, a colour-coded category chip (Renal & PK, Dosing, Risk Scoring, Dose Adjustment, Lab Interpretation, or Stewardship), and a 1–3 star Nigeria-relevance rating.
• Inputs panel (left, or full-width on mobile) — the fields specific to that calculator.
• Result panel (right) — appears once you've filled in the required fields; shows the primary value, an interpretation sentence, and any recommendations or warnings.

History

Click the clock icon at the top right of any calculator to open its history drawer — your past calculations on that specific tool, saved so you can refer back to a result without re-entering the patient's values. History is per-tool, not shared across calculators.

The disclaimer

Every result carries the same line:

For clinical reference only. Always verify with current prescribing information and clinical judgment before making any clinical decision.

This isn't boilerplate — none of these tools override your judgment or a drug's actual prescribing information; they're calculation aids, not a substitute for either.

Warnings vs. blocks

Most calculators show warnings — flags like "dose exceeds the maximum single dose, capped at max" or "low creatinine may reflect reduced muscle mass in older patients" that appear alongside a real result you can still use. A few (Paediatric Weight-Based Dosing, Malaria ACT Dosing) can block a result entirely — for example, a weight below the tool's minimum validated threshold — and show a message telling you why, with no number to act on. If you see a block, the answer is to seek specialist input for that specific case, not to look for a way around it.

Cross-tool handoff

Some tools feed into others — a Creatinine Clearance result that shows dose-adjustment is needed links directly to Renal Dose Adjustment; a Child-Pugh score links to Hepatic Dose Adjustment; a CURB-65 score can feed straight into the Antibiotic Stewardship Advisor's severity selection. Look for a "Use in..." link under a result — it carries the value across so you don't have to re-enter it.
