Your pharmacists already know. Your software should too.

One HIPAA-compliant interface. Real-time formulary checks, controlled substance tracking, and 21 CFR Part 11 audit trails — from first keystroke to dispensing event.

01 / INTEGRATION

Integration

API connectivity, EHR handshakes, and HL7 FHIR R4 compliance.

99.97%
API uptime SLA
Legacy e-prescribing stacks average 3.2 discrete system logins per fill event. Prescribe presents a single authenticated session across formulary, DEA scheduling, and prior auth — one token, one audit trail.

02 / COMPLIANCE

Compliance

21 CFR Part 11, HIPAA Security Rule, DEA EPCS, and state PMP reporting.

0 FTE
Validation overhead
The median health system spends 1,840 staff-hours per year on e-prescribing audit preparation. Prescribe generates IQ/OQ/PQ documentation continuously — not retrospectively.

03 / SPEED

Speed

Formulary lookup latency, prior auth queue throughput, and fill-to-dispense cycle time.

4.2s
Formulary lookup
A 38-second formulary lookup is not a UX problem — it is a patient safety problem. At 200 fills per shift, that is 2.1 hours of pharmacist time consumed by a spinner.

* Formulary lookup latency measured via synthetic monitoring across Surescripts, DrFirst, and Allscripts production APIs, Q4 2025. Prior auth cycle time from CMS 2024 Prior Authorization Burden Report. Prescribe figures from production telemetry (p50/p95 across 84 health system customers).

03 / BENCHMARK

Run your pharmacy's baseline report.

Three fields. We calculate your current system's cost-per-fill, error exposure, and compliance gap against Prescribe's validated benchmarks.

$prescribe-cli benchmark --init

No credit card. No sales call. Your report is generated automatically and delivered within 60 seconds. Data is not shared with third parties.

04 / ACCURACY

Accuracy

Error rates per 1,000 fills, DDI miss rate, and dosing override frequency.

Errors / 1k fills
The Institute for Safe Medication Practices estimates 1 in 100 e-prescriptions contains a clinically significant error. Prescribe's dual-model DDI engine cross-references FDA Orange Book, Lexicomp, and real-time NDC data simultaneously.

05 / COST

Cost

Total cost of ownership: licensing, validation overhead, integration labor, and error-related liability.

−70%
3-year TCO delta
Licensing is rarely the largest line item. For a 400-bed system, integration labor and annual validation maintenance typically exceed the platform fee by 3.4×. Prescribe's TCO model inverts this.
