How Precover decides Proceed, Prepare, or Pause

Precover is a patient-facing decision-support tool. The readiness signal is produced by a deterministic rules engine — not a language model. This page describes exactly how the engine works, how often it is reviewed, what it is for, and where it stops.

The deterministic rules engine

Each rule has a stable code, a severity tier (Proceed / Prepare / Pause), the input it reads, and the citation that backs it. When you submit a screening, the engine runs every rule against your answers and returns the exact list of rules that fired with their severities. Anyone — you, your surgeon's coordinator, an auditor — can replay why the engine produced the signal it did. AI is never used to decide your readiness.

What AI is used for

AI is used for two narrow tasks only: parsing free-text medication entries into a structured list (brand, generic, dose, frequency) and rewriting clinical bullets into patient-friendly summaries. AI never assigns severity, never decides Proceed / Prepare / Pause, and never overrides a rule.

Review cadence

The rule set and patient guides are re-reviewed on a calendar cadence and on demand:

  • Quarterly calendar review of every rule against current society guidance (ASA, ASPS, AANA, SASM, ASPEN, ERAS).
  • Within 30 days of any new society statement that materially changes a rule (e.g., GLP-1 perioperative guidance, anticoagulant bridging).
  • Patient guides carry a visible Reviewed date and are bumped on every rule change.
  • Corrections are accepted at editorial@precover.app and triaged within five business days.

Scope

  • Adults 18+ residing in the United States.
  • Elective cosmetic surgery — small, moderate, and major body-contouring procedures.
  • Inputs: procedure category, medical and surgical history, anesthesia history, medications and supplements, STOP-Bang sleep apnea screen, nutrition, and lifestyle.
  • Outputs: plain-English readiness summary, surgeon-facing consultation packet, optional Recovery Kit and Premium Recovery Plan.

Explicit limits — what Precover does not do

  • Precover does not provide medical advice, does not diagnose, and does not clear anyone for surgery or anesthesia.
  • Precover does not replace a pre-op H&P, anesthesia evaluation, lab work, EKG, or any specialist consultation your team orders.
  • Precover is not used in emergencies. If you are experiencing chest pain, severe shortness of breath, stroke-like symptoms, fainting, or severe bleeding, call your local emergency number.
  • Precover is not a HIPAA covered entity. See the Privacy Policy for our position.
  • Precover does not message your surgeon for you — sharing only happens when you copy the link or download the PDF.

Conflicts of interest

Precover earns affiliate commissions on a small number of Recovery Kit items and sells a one-time $29 Premium Recovery Plan. Affiliate or commercial relationships never change which rules fire or how readiness is scored. The rules engine is independent of the commerce surface and is auditable in the rule list returned with every result.
