Predictions and prescribing
health.hayaterp.com ↗For doctors — the risk flags Hayat Health raises from guideline rules (diabetes, hypertension, CKD, anaemia, dyslipidaemia, thyroid, liver, BMI, vitamin D) and from trained models, with their inputs and guideline; confirm, reject or share with the patient; trend projections; generic medicine suggestions with allergy, kidney, liver, pregnancy and interaction checks; anticipated needs; and writing and approving prescriptions.
Everything on this page is decision support for a licensed doctor. The patient sees nothing here until you share or approve it. You need the patient's predictions consent for flags and the medicines consent for suggestions and prescriptions.
Risk flags
Hayat looks at every patient's confirmed values (after each new value, and once a day) and raises flags for you to review. Each flag shows its title, stage, severity (info, watch, high, urgent), the plain explanation, the inputs used (each value with its date), the rule and the guideline it follows, and a confidence.
Rule flags work from the first day:
| Area | Examples | Guideline |
|---|---|---|
| Diabetes | Confirmed (two diagnostic results), possible, prediabetes — HbA1c ≥ 6.5 % / 5.7–6.4 %, FBS ≥ 126 / 100–125 | ADA 2025 |
| Hypertension | High-normal, grade 1, 2, severe — from the 30-day home average (≥ 3 readings on ≥ 2 days) | ISH 2020 |
| Kidney | CKD G / A stage from eGFR (CKD-EPI 2021) and UACR; chronic vs possible; rapid decline | KDIGO 2024 |
| Anaemia | Mild / moderate / severe by sex and pregnancy; iron-deficiency hint (MCV, ferritin) | WHO 2024 |
| Lipids | LDL ≥ 190 / 160 / 130, TC ≥ 240, low HDL, TG ≥ 150 and ≥ 500 | ACC/AHA 2018 |
| Thyroid | TSH > 10, 4.5–10, < 0.1, 0.1–0.4 (with FT4) | ATA |
| Liver | ALT / AST patterns (fatty liver, hepatitis, acute), cholestatic | ACG 2017 |
| Weight | BMI with Asian cut-offs (23 / 27.5) | WHO 2004 |
| Vitamin D | < 20, < 12 ng/mL | — |
Model estimates (e.g. risk of progressing from prediabetes to diabetes in 12 months, CKD stage change, BP staying uncontrolled) appear only when the Hayat team has trained and activated a model that passed its quality checks, and only above a minimum probability. They show the model version and the probability.

Review a flag
| Action | Effect |
|---|---|
| Confirm (optional note, condition name, stage) | Adds the condition to the patient's record; counts as a "yes" label for training |
| Reject (optional note) | Closes the flag; counts as a "no" label |
| Share with patient (note required) | The patient sees the finding with your note and a disclaimer, and gets a notification |
| Unshare | Hides it from the patient again |
Write the share note for the patient: what it means for them and what to do next. You can also add or resolve conditions yourself.
Projections
A test's chart shows a dotted projection for the next months from the patient's own values (at least 4 over 30 days or more), with an uncertainty band — e.g. HbA1c, weight, BP. It is labelled a projection: a trend, not a prediction or a diagnosis.
Medicine suggestions
For each confirmed or flagged condition you see first-line and second-line generic options from the guideline — e.g. type 2 diabetes → metformin (unless eGFR < 30), hypertension → amlodipine, an ACE inhibitor or an ARB, dyslipidaemia → a statin — with strengths, the usual dose, frequency and days, informational brand examples, and a safety level:
| Safety | Means |
|---|---|
| OK | No problem found in the record |
| Caution | Something to weigh — e.g. reduce the dose for eGFR 30–45 |
| Avoid | A clear reason not to — allergy group, eGFR below the limit, pregnancy, liver disease, high potassium, a serious interaction, or a duplicate of a current medicine |
Each check says what it found (eGFR 28 — avoid below 30). Checks use only what is in the record: an empty allergy list means none recorded, not none.
Anticipated needs lists trends that suggest therapy may soon be indicated — e.g. LDL rising towards the statin threshold, with the projected date — and current medicines due for review. Refills shows when each prescribed medicine runs out.
Patients never see suggestion lists.
Write and approve a prescription
- Start a prescription for the patient — from a suggestion or blank. Add lines: generic (from the catalogue or typed), strength, dose, frequency, route, days, quantity, instructions. Add the diagnosis, notes and start date.
- Save: it is a draft. Each line is checked again and shows its warnings.
- Edit as needed. Only you can edit your drafts.
- Approve. If any line has an avoid warning you must confirm that you have considered the warnings.
- The patient is notified and sees the prescription (numbered
HRX-…) — without the warning text. A linked Hayat hospital pharmacy can fill it.
Cancel a prescription with a reason; the patient sees it as cancelled.
