OpenEvidence Prompt Refinement

Overview

Tune context and question structure while holding clinical accountability and source review constant. Keep inputs minimal, separate observed facts from assumptions, and leave consequential decisions with the named accountable owner.

Prerequisites

• A clearly bounded workflow, accountable clinical owner, and organizational policy
• Current first-party OpenEvidence documentation and applicable institution agreements
• Synthetic or properly authorized minimum-necessary data

Tool Discipline

Use Read, Glob, and Grep to inspect supplied policies, plans, and evidence. Use WebFetch only for current first-party OpenEvidence documentation. Use Write or Edit only when the user requests a named deliverable with an approved destination. Never expose credentials, PHI, recordings, or unrestricted environment output.

Current Contract

• The official guide publishes prompt guidance and dedicated workflows for complex cases and Snow.
• More detail is not always safer; include only relevant, authorized context.
• Performance means decision usefulness and evidence traceability, not fastest answer or longest response.

Authentication

Use only the official OpenEvidence web/mobile sign-in or an institution-approved access path. Do not invent API keys, OAuth clients, SDK credentials, service accounts, or private endpoints. Never ask a user to reveal a password, session token, cookie, or recovery code.

Instructions

1. State the decision, intended user, population, outcome, constraints, and what uncertainty must remain visible.
2. Remove identifiers and irrelevant narrative; separate known facts from assumptions.
3. Run a baseline synthetic or authorized de-identified question and score relevance, citations, applicability, and reviewer effort.
4. Change one prompt element at a time: specificity, timeframe, comparator, output structure, or request for conflicting evidence.
5. Open citations and have a qualified clinician compare versions using the same rubric.
6. Save a reusable pattern only if it improves the defined outcome across multiple representative cases.

Approval Boundaries

Do not create or share accounts; change access, roles, agreements, consent, retention, or security settings; enter PHI; record a conversation; copy content into another system; contact a patient; make a diagnosis or treatment decision; submit billing; transmit a support packet; run a production pilot; or represent vendor capabilities without explicit approval from the accountable owner. A qualified professional remains responsible for clinical decisions.

Output

Return scope, current first-party evidence and date, data classification, workflow or findings, citations reviewed, assumptions rejected, clinical and governance owners, approval state, unresolved risk, and the exact next action. Redact patient and credential data.

Error Handling

Examples

This compact example shows the minimum reviewable handoff; adapt fields to the approved workflow without adding sensitive data.

Input:

decision=diagnostic workup; context=de-identified; variants=3; reviewer=clinician

Expected handoff:

best-variant=2; traceability=improved; uncertainty=preserved; template=approved
