Meridian Smart Hospital — Information Systems Simulation

System 1 · Generic / CBIS

Registration & scheduling

Awaiting input

A traditional clerk checks a paper appointment book, telephones each doctor's office and writes a card. Here the generic system reads the master availability table, matches the specialty, verifies room rules and writes the record itself. You supply a name and an age.

Patient name Age Requested specialty

1 · InputName, age and specialty captured once.

2 · ValidateAge range, duplicate record, coverage.

3 · MatchAvailability table plus room rules.

4 · StoreAppointment committed to the record.

One database read, one write. No phone tree.

System 2 · Transaction processing

Billing & settlement

ACID enforced

The invoice is already compiled from the consultation code and the diagnostics the physician logged. Your only decision is the payment method; authorisation, ledger update, inventory deduction and receipt happen as one indivisible transaction.

Compiled invoice

Cardiology consultation · C-114	25.000 OMR
12-lead ECG · D-207	12.000 OMR
Lipid panel + fasting glucose · L-031	8.500 OMR
Total due	45.500 OMR

IoT telemetry · continuous capture

Bedside monitoring

Monitor idle

A networked monitor streams vitals straight into the clinical database, so no nurse transcribes numbers onto a chart. Watch the heart rate: it drifts downward on its own, and nobody has touched a clipboard.

Threshold breach — heart rate 46 bpm, sustained 12 s

Systolic pressure falling in parallel. The rule fired automatically from the clinical database; no human witnessed this drop.

System 3 · Decision support · prescriptive

Decision support: 46 bpm at rest

Awaiting clinician

The DSS does not decide. It correlates the live trace with years of history, tests that evidence against clinical rules and lays out scored options. The judgement stays human; the evidence simply stops being scattered across paper folders.

Evidence assembled

Live telemetry — HR 46 bpm, BP 101/68, SpO₂ 96%.
Visit history — resting HR 52–58 bpm across six visits since 2021.
Pharmacy record — bisoprolol 2.5 mg daily, a rate-limiting agent.
Knowledge base — documented sinus bradycardia, asymptomatic, known baseline.
Symptom check — no syncope, no dizziness, no chest pain.

Hypotheses scored

Stable sinus bradycardia — known baseline74%

Acute symptomatic bradycardia / high-grade block26%

Sensitivity check: without the historical record the same model returns 61% acute. The chart is what changes the answer — which is the entire argument for an integrated system.
