Project Overview - -Pediatric AI Scribe is a clinical documentation platform for pediatric healthcare providers. It uses AI (via OpenRouter, AWS Bedrock, or Azure OpenAI) to generate: - -- HPI notes from live encounter recordings -- SOAP notes from dictation -- Hospital course summaries -- Chart reviews -- Well-visit notes (including SSHADESS, ROS/PE, milestones) -- Sick visit notes -- Learning Hub content (articles, quizzes, clinical pearls, presentations) - -**Key design principle:** Single-page application. All tabs are lazy-loaded HTML components (`/public/components/*.html`). JavaScript modules initialize only when their tab is first activated via the `tabChanged` custom event. - ---- - -## 2.

All queries use parameterized placeholders (`$1`, `$2`) to prevent SQL injection -6. **Response** is JSON for API calls, or static files served from `/public` - -### AI Providers - -Configured via environment variables. The provider is selected at startup in `src/utils/ai.js` using this priority: - -1. **AWS Bedrock** — if `AWS_BEDROCK_REGION` is set. HIPAA eligible with BAA. Uses `@aws-sdk/client-bedrock-runtime`. Anthropic models use the native Messages API (`InvokeModel`); all others use the Converse API. -2. **Azure OpenAI** — if `AZURE_OPENAI_ENDPOINT` is set. HIPAA eligible. Uses the OpenAI SDK pointed at your Azure endpoint. -3. **OpenRouter** — default fallback if `OPENROUTER_API_KEY` is set. Routes to 20+ models from various providers. Not HIPAA compliant. - -The provider cannot be changed at runtime — it's determined once at startup. To switch providers, update `.env` and restart the container. - -### Database Layer - -The app uses **raw SQL via the `pg` driver** — no ORM (Sequelize, Prisma, etc.). This is intentional: - -- **Simplicity:** Every query is visible and explicit. No magic, no migrations framework, no model definitions to sync. -- **Performance:** No ORM overhead or N+1 query problems. -- **Schema management:** `src/db/database.js` runs `CREATE TABLE IF NOT EXISTS` on startup, plus `ALTER TABLE ... ADD COLUMN IF NOT EXISTS` for migrations. This means the schema is always up-to-date when the app starts. -- **Future ORM migration:** If needed, the queries are standard PostgreSQL and can be wrapped by any ORM. The main work would be defining models and replacing direct `db.get()`/`db.run()` calls. - -The `database.js` file exports a helper object (`db`) with convenience methods: -- `db.get(sql, params)` — returns first row or `null` -- `db.all(sql, params)` — returns all rows as array -- `db.run(sql, params)` — executes INSERT/UPDATE/DELETE, returns `{ rowCount }` -- `db.getSetting(key)` / `db.setSetting(key, value)` — shorthand for `app_settings` table - ---- - -## 3.

Authentication System - -**Current implementation: JWT in localStorage** - -### Flow -1. `POST /api/auth/login` → returns `{ success, token, user }` -2. Frontend stores token in `localStorage` as `ped_scribe_token` and in `window.AUTH_TOKEN` -3. All API calls include `Authorization: Bearer ` header via `getAuthHeaders()` -4. `src/middleware/auth.js` validates the Bearer token, attaches `req.user` -5. Logout: `clearSession()` removes token from localStorage (client-side only) - -### Token -- Signed with `JWT_SECRET` env var -- 7-day expiry -- Payload: `{ userId: number }` - -### Roles -- `user` — standard access (clinical tools only) -- `moderator` — can create/edit Learning Hub content -- `admin` — full access including user management and site settings - -### Middleware -- `authMiddleware` — validates JWT, populates `req.user` -- `adminMiddleware` — run after auth, requires `role === 'admin'` -- `moderatorMiddleware` — run after auth, requires `role === 'admin' OR 'moderator'` - -### 2FA -Uses TOTP (speakeasy). If enabled, login returns `{ requires2FA: true }` and the client must POST the TOTP code to complete login. - -### Session Check on Page Load (auth.js) -```javascript -var savedToken = localStorage.getItem('ped_scribe_token'); -if (savedToken) { - fetch('/api/auth/me', { headers: { 'Authorization': 'Bearer ' + savedToken } }) - .then(/* if ok → enterApp(), else → clearSession() */); -} -``` -The `has-session` CSS class on `` hides the auth screen immediately when a localStorage token exists, preventing a white flash. - ---- - -## 7.

---- - -## 8. Frontend Architecture - -### Tab Loading (Lazy Components) -Every tab's HTML lives in `/public/components/.html`. When a tab button is clicked, `loadComponent()` in `app.js` fetches the HTML, injects it into the tab section, then fires `tabChanged` event. - -```javascript -// app.js -document.dispatchEvent(new CustomEvent('tabChanged', { detail: { tab: tabName } })); -``` - -**Critical pattern:** Every JS module that needs to access tab DOM elements MUST listen for `tabChanged`, not `DOMContentLoaded`: - -```javascript -// Correct pattern for every tab module -(function() { - var _inited = false; - document.addEventListener('tabChanged', function(e) { - if (e.detail.tab !== 'myTab' || _inited) return; - _inited = true; - // Now safe to querySelector elements — they exist in the DOM - var btn = document.getElementById('my-btn'); - btn.addEventListener('click', ...); - }); -})(); -``` - -If you use `DOMContentLoaded` instead, the elements won't exist yet (they're loaded async) and you'll get `null.addEventListener` errors. - -### Global Functions (defined in app.js) -These are available everywhere — no imports needed: - -| Function | Description | -|----------|-------------| -| `getAuthHeaders()` | Returns `{ 'Content-Type': 'application/json', 'Authorization': 'Bearer ' }` | -| `getSelectedModel()` | Returns model ID from active tab's selector or global selector | -| `showLoading(msg)` | Shows full-screen loading overlay | -| `hideLoading()` | Hides loading overlay | -| `showToast(msg, type)` | Shows toast notification. `type`: `'success'`\|`'error'`\|`'info'`\|`'warning'` | -| `setOutputText(el, text)` | Sets text on contenteditable div, converting `\n` to `
` | -| `transcribeAudio(blob)` | Sends audio blob to `/api/transcribe`, returns `{ success, text }` | -| `createSpeechRecognition()` | Returns Web Speech API recognition instance | -| `createTimer(el)` | Returns timer object with `.start()` / `.stop()` | - -### Rich Text Editor (Tiptap) -The body editor in the CMS uses Tiptap 2 (headless, no styling framework). The bundle is pre-built at `/public/vendor/tiptap.bundle.js` and exposes `window.Tiptap = { Editor, StarterKit, Link, Underline, TextStyle, Color }`. - -To rebuild the bundle after updating Tiptap packages: -```bash -cat > tiptap-entry.js << 'EOF' -import { Editor } from '@tiptap/core'; -import StarterKit from '@tiptap/starter-kit'; -import Link from '@tiptap/extension-link'; -import Underline from '@tiptap/extension-underline'; -import { TextStyle } from '@tiptap/extension-text-style'; -import { Color } from '@tiptap/extension-color'; -window.Tiptap = { Editor, StarterKit, Link, Underline, TextStyle, Color }; -EOF -npx esbuild tiptap-entry.js --bundle --format=iife --minify --outfile=public/vendor/tiptap.bundle.js -rm tiptap-entry.js -``` - ---- - -## 9. AI Integration - -### `src/utils/ai.js` — `callAI(messages, options)` - -The single function used by all routes. It routes to the correct provider automatically. - -```javascript -const { callAI } = require('../utils/ai'); - -const result = await callAI( - [{ role: 'user', content: 'Generate a note...' }], - { - model: 'google/gemini-2.5-flash', // optional, uses default if omitted - temperature: 0.3, // optional, default 0.3 - maxTokens: 4000 // optional, default 4000 - } -); - -// result = { success: true, content: '...', model: '...', provider: '...', duration: ms } -``` - -### Bedrock Model Notes - -**Inference Profiles:** Most newer Bedrock models require cross-region inference profiles. These use a `us.` prefix on the model ID (for example, `us.amazon.nova-pro-v1:0`). Direct model IDs may return "on-demand throughput not supported" errors. - -**Max Output Tokens:** Some models have low output limits (Cohere Command R/R+: 4096, AI21 Jamba: 4096). The `maxOut` field in `models.js` auto-clamps `maxTokens` in `callBedrock()`. - -**JSON Sanitization:** Some models output literal newline characters inside JSON string values. `learningAI.js` includes a `sanitizeJsonString()` function that escapes these before parsing. - -### Prompt System -Prompts are defined in `src/utils/prompts.js`. Admins can override any prompt via the Admin panel (`/admin/config/prompts`). Overrides are stored in `app_settings` table and loaded into memory on startup (with 3s grace period for DB readiness). - -To add a new prompt: -1. Add a default in `prompts.js` -2. Use `PROMPTS.get('your-prompt-key')` in your route -3. The admin panel will auto-discover it - -### AI Generate for Learning Hub -The `src/routes/learningAI.js` file handles all Learning Hub AI generation. - -**For presentations:** The AI is prompted to return raw Marp markdown (not JSON). The response is stored in the `body` column. Detection: `content_type === 'presentation'`. - -**For articles/quizzes/pearls:** The AI returns JSON: -```json -{ - "title": "...", - "subject": "...", - "body": "

HTML content

", - "questions": [ - { - "question_text": "...", - "question_type": "mcq", - "explanation": "...", - "options": [ - { "option_text": "...", "is_correct": true, "explanation": "..." } - ] - } - ] -} -``` - ---- - -## 10. Learning Hub & CMS - -### Content Types -| Type | Body format | Has questions | -|------|-------------|---------------| -| `article` | HTML (Tiptap) | Optional | -| `quiz` | HTML (brief intro) | Always | -| `pearl` | HTML | Optional | -| `presentation` | Marp markdown | Never | - -### Quiz Question Types -- `mcq` — Single choice (radio buttons), 4 options, 1 correct -- `true_false` — 2 options: "True" / "False", 1 correct -- `multi` — Multiple select (checkboxes), scoring: all correct chosen AND no incorrect chosen - -### PPTX Generation -`POST /admin/learning/generate-pptx` parses Marp markdown (splits on `---`), extracts `#` headings as slide titles, bullet points as content, and uses `pptxgenjs` to create a real `.pptx`. **No Chromium required** — pure Node.js. - -### Slide Preview -`POST /admin/learning/preview-slides` uses `@marp-team/marp-core` to render Marp markdown to HTML, then extracts individual `
` elements. Returns `{ css, slides[] }`. The frontend renders these one at a time in a full-screen modal with arrow key + swipe navigation. - -### Content Display -In the Learning Hub viewer, content `body` is rendered via `sanitizeHtml()` in `learningHub.js`. This function allows a safe subset of HTML tags only (no `` -3. Create `public/js/myTab.js`: - ```javascript - (function() { - var _inited = false; - document.addEventListener('tabChanged', function(e) { - if (e.detail.tab !== 'mytab' || _inited) return; - _inited = true; - // Wire up DOM elements here - }); - })(); - ``` -4. Create `src/routes/myTab.js` with the API route -5. Register in `server.js`: `app.use('/api', require('./src/routes/myTab'));` - -### Adding a New AI Prompt -1. In `src/utils/prompts.js`, add to the defaults object: - ```javascript - 'my-prompt': 'You are a pediatric physician...' - ``` -2. In your route: `const prompt = PROMPTS.get('my-prompt') + '\n\n' + userInput` -3. The admin panel will show an editor for this prompt automatically. - -### Adding a New Learning Hub Content Type -1. Add the new type to the `content_type` selector in `cms.html` -2. Handle it in `toggleEditorMode()` in `learningHub.js` -3. Add to the type detection in `buildGeneratePrompt()` in `learningAI.js` -4. Handle rendering in `learningHub.js` `loadContent()` function -5. No DB migration needed — `content_type` is a free-text column - ---- - -## 14.

PDF & Document Uploads - -### How It Works - -The Learning Hub AI generator accepts documents via two paths — both produce the same result: - -1. **Direct upload** — user selects a file from their computer (up to 20 MB) -2. **Nextcloud WebDAV** — user browses their Nextcloud and picks a file - -The flow: -1. `extractText()` in `learningAI.js` detects file type by MIME/extension -2. **PDF:** `pdf-parse` v1.1.1 extracts all text pages into a single string -3. **PPTX/DOCX/TXT:** extracted via appropriate parser or read as UTF-8 -4. Text is truncated to **50,000 characters** (~25-30 pages) and sent as context in the AI prompt -5. AI generates structured content (title, HTML body, quiz questions) from the full context - -### Supported File Types -| Extension | Handler | Notes | -|-----------|---------|-------| -| `.pdf` | `pdf-parse` | Extracts text only — images, charts, tables are lost | -| `.pptx` | Text extraction from slides | Slide text only | -| `.docx` | Text extraction | Body text only | -| `.txt`, `.md`, `.csv` | Read as UTF-8 | Full content preserved | - -### Limits -- **Upload size:** 20 MB (`multer` limit in `learningAI.js`) -- **Context sent to AI:** 50,000 characters (configurable in `buildGeneratePrompt()`) -- **AI response tokens:** 8,000 max (ceiling — model stops when done) - -### Why No Vector Embeddings / RAG - -Embeddings and RAG (Retrieval Augmented Generation) are unnecessary for this use case: - -- **Single document → single generation** — the full text fits in the model's context window -- Most Bedrock models support 100K-200K token inputs — 50,000 chars is well within that -- Embeddings would add complexity (pgvector, chunking, retrieval pipeline) with no benefit - -If you later need to **search across hundreds of stored documents** or handle 200+ page PDFs, then consider pgvector + chunked retrieval.

Security Architecture — localStorage vs httpOnly Cookies - -The app stores JWT tokens in `localStorage`. This is a deliberate choice appropriate for this scale. The key security facts: - -**Current protections in place (more important than storage location):** -- `Content-Security-Policy: script-src 'self'` — blocks all external scripts and inline JS (v3.18) -- Input sanitization via `sanitizeHtml()` allowlist on all user-generated HTML -- All 26 `onclick=` inline event handlers removed (v3.18) — reduces XSS surface -- Rate limiting on auth endpoints -- Helmet.js security headers -- Parameterized SQL queries throughout - -**The reality about localStorage vs httpOnly cookies:** -> "Unless you're a bank or large enterprise, it doesn't really matter. Focus on preventing XSS, because that's what actually matters... fundamentally, the security benefit of using httpOnly cookies is very minimal. If your site suffers any kind of XSS, it makes it slightly more difficult for an attacker to use the auth token." — Security engineering community consensus - -httpOnly cookies prevent token *copying* but not token *use* — an XSS attacker can still make authenticated requests on the user's behalf regardless of where the token is stored. - -**If you later want httpOnly cookies:** The infrastructure is already in place (cookie-parser, CORS `credentials:true`). The change is: (1) set cookie on login, (2) remove token from `getAuthHeaders()`, (3) add `/api/auth/logout` to clear cookie. See notes in `auth.js`. This was implemented and reverted in v3.14 — it works but adds CSRF considerations. - -**Token lifetime:** Currently 7 days. For higher security, reduce to 1-2 hours and add refresh token rotation. - ---- - ---- - -*Last updated: March 2026 — v6.0* -*Generated for developer handover.* +# Pediatric AI Scribe Developer Guide + +This page used to be a long, hand-maintained developer guide.

Lifecycle walkthrough — clicking "Generate" on a sick visit - -A worked example of how the layers compose. Tab: Sick Visit. - -1. **Frontend collects inputs.** `sickVisit.js` reads: - - The transcript area, populated by the configured transcription API or - the explicit opt-in browser speech-recognition fallback. - - The structured ROS / PE radio buttons (NORMAL / ABNORMAL / NOT - REVIEWED + free-text per-system notes). - - Patient age and chief complaint. - - The selected model (`getSelectedModel()` — tab-level dropdown wins - over global). -2. **Optional template injection.** `getUserMemoryContext()` pulls saved - AI-context templates and preferences from `/api/memories/context`. -3. **POST to /api/sick-visit.** The route: - - Wraps every user-derived chunk in `` blocks via - `wrapUserText`. - - Builds the messages array: system prompt = `PROMPTS.sickVisitNote + - INJECTION_GUARD`; user content = the wrapped data. - - Calls `callAI(messages, { model, maxTokens })`. -4. **`callAI` runs the allowlist check, routes to the active provider's - `callX`, normalises the response, logs the API call to `api_log`.** -5. **Route returns `{success, content, model}`.** -6. **Frontend `setOutputText(noteEl, content)`** — escapes HTML, converts - `\n` to `
` so line breaks survive in the contenteditable output. -7. **`storeSourceContext(noteEl, originalTranscript)`** — saves the raw - transcript on the output's `dataset.sourceContext` so a later refine - can reference it. -8. **The helper trio fires automatically.** `sickVisit.js` calls (in - parallel, all silent on failure): - - `suggestBillingCodes(noteEl.id, content, 'soap', age, 'outpatient')` - → ICD-10 + CPT chips appear under the note. - - `suggestDontMiss(noteEl.id, content, 'sickvisit', age, cc)` → orange - Don't-Miss card appears. -9. **The user reads the note**, optionally clicks Refine ("make the - assessment more concise"), which calls `refineDocument` (§12.1) and - replaces the note text in place — passing `sourceContext` so the - refine pass has access to the original transcript. - ---- - -## 15. Sacred zones — "fix only named bugs" - -Per `MEMORY.md` rules `feedback_voice_stt_sacred` and the cross-cutting -"don't refactor recorder/transcribe plumbing": - -- `public/js/audioBackup.js` — server-first, IndexedDB-fallback save - path. Touch only if a specific bug is reported. -- `public/js/speechRecognition.js` — the live-streaming preview wrapper - (and `app.js`'s `createSpeechRecognition`). Both exist for a reason - (one is a real opt-in transcript path, one is just a visual preview); - unifying them would break tabs. -- `public/js/voicePreferences.js` — STT model + TTS voice picker UI. -- `public/js/transcriptionSettings.js` — explicit Web Speech setting and - transcription preference UI. -- `public/js/app.js` — the `AudioRecorder` class (lines 659–683) and the - `transcribeAudio` / `_serverTranscribe` chain (lines 739–795). - -Specifically: do **not** propose: -- Refactoring `transcribeAudio` to use a "TranscriptionRouter" class. -- Splitting `AudioRecorder` into separate start/stop modules. -- Changing the 32 kbps Opus / 1-second slice / mono / 16 kHz config. -- Centralising the audio-backup save logic with the upload logic. - -Each of those would touch all eight clinical tabs and risk breaking -recordings in subtle, hard-to-test ways. - ---- - -## 16. How to add a new AI provider - -Concrete checklist if you want to add, say, a new provider `Acme`: - -1. **Add a client init block in `src/utils/ai.js`** (model after the - existing OpenRouter / Bedrock blocks at lines 16–111). Guard on a - uniquely-named env var (e.g. `ACME_API_KEY`). Set - `activeProvider = 'acme'` on success. -2. **Add a `callAcme(messages, model, temperature, maxTokens)` function** - following the shape of `callOpenRouter` (lines 155–172). It must - return the unified shape: - `{success, content, model, provider: 'acme', usage}`. -3. **Add the validation guard** in the boot section (lines 130–148): - ```js - if (activeProvider === 'acme' && !acmeClient) { - console.log('⚠️ Acme selected but not available. Falling back to OpenRouter.'); - activeProvider = 'openrouter'; - } - ``` -4. **Add the routing branch** in `callAI` (lines 437–449): - ```js - else if (activeProvider === 'acme' && acmeClient) { - result = await callAcme(messages, model, temperature, maxTokens); - } - ``` -5. **Optional: add fallback support** in lines 478–514 if you want this - provider to participate in the opt-in fallback chain. -6. **Add a model list to `src/utils/models.js`.** Define `ACME_MODELS` - following the shape of `BEDROCK_MODELS` etc. Add a switch case in - `getAvailableModels` (line 142), `getDefaultModel` (line 157), - `getFallbackModel` (line 168). If model IDs need translation - (friendly id → vendor-specific id), add a `getAcmeModelId` like - `getBedrockModelId` (line 179). -7. **Optional: add discovery support** in `discoverModels` (lines 524–633) - if Acme has a `/v1/models` endpoint. Otherwise the static list is - fine. -8. **Add env-var documentation** to `.env.example` and `docs/ai-providers.md`. - -That's the entire integration surface — no route changes are needed, -because every route already calls the abstract `callAI`. The same applies -in spirit to STT: a new STT backend goes in `src/utils/transcribeAcme.js`, -gets a branch in `src/routes/transcribe.js`'s `getTranscribeProvider` and -the router's switch, and is done. +1. Keep provider-specific code inside utility/provider modules. +2. Wrap all user-derived text with `wrapUserText` before AI calls. +3. Do not add browser-local Whisper back without a new design review. +4. Do not add clinical answer response caching. +5.

Same plumbing as every other - clinical tab. -4. **Click "Generate Stage 1 Note".** Frontend POSTs to - `/api/ed-encounters/generate` with `{stage: 1, transcript, chiefComplaint, - patientAge, patientGender, physicianMemories, model}`. Server returns - `{success, note, dontMiss[], model}`. Note appears as **Stage 1** card. - Don't-miss items appear as a yellow/orange section embedded in that same - card. -5. **Edit if needed.** Each stage's note element is `contenteditable`. Type - freely; edits persist to localStorage on each input event. -6. **Refine the latest stage** (optional). The "Refine latest" textarea + - button at the bottom of the stage list calls `/api/refine` with the - latest stage's text + your instruction. The latest stage's text is - replaced inline with the refined version. -7. **Add another stage** (optional). Click "Add more (next stage)". Stage 1 - card stays visible. Transcript box clears. Badge changes to "Stage 2 - (recording)" — yellow background — meaning we've advanced but no Stage 2 - note has been generated yet. -8. **Repeat** for as many stages as you need. -9. **Click "Save & Done (with MDM)"** at any point. - - Server runs `edConsolidate` → produces one polished final note that - integrates every stage chronologically. - - Server then runs `edFinalize` → produces a 2023 E/M MDM block as JSON. - - Both come back in one HTTP response. - - Frontend renders a **"Final Consolidated Note"** card (blue left border) - and a **"Medical Decision Making (2023 E/M)"** card (green left border) - below the stage cards. - - Stage cards become read-only. - - The whole thing persists to `saved_encounters` with `status='final'`. - - Local draft cleared. +When changing ED behavior: ---- - -## 3. State model - -Lives in a closure variable in `public/js/ed-encounters.js`: - -```js -_state = { - stage: 1, // current stage number (what the recorder is for) - stages: [ // per-stage history — one entry per generated stage - { transcript, note, dontMiss[], model, generatedAt } - ], - finalized: false, - finalNote: null, // consolidated final note from /finalize - mdm: null // 2023 E/M MDM block from /finalize -} -``` - -### Invariants - -- `_state.stage` increments monotonically. It only goes up via the user - clicking "Add more". It is the **target** stage of the recorder/generate - button. -- `_state.stages.length` is the number of stages **already generated**. The - array is indexed 0..N-1; stage 1 is at index 0, stage 2 at index 1, etc. -- The relationship `_state.stages.length === _state.stage` means "the - current stage has been generated, ready to finalize or advance." -- The relationship `_state.stages.length === _state.stage - 1` means - "we're recording into a new stage that hasn't been generated yet" (the - yellow `Stage N (recording)` badge state). -- `_state.finalized` flips to `true` only when finalize succeeds. Once true, - Add more / Generate / Refine all reject with a toast. - -### Why this shape - -Earlier iterations stored a single `currentNote` string and rotated stages -out of view on each generation. Daniel's clarification was explicit: every -stage's note must remain visible and editable; the final MDM should reflect -whatever's on screen, including any inline physician edits to earlier stages. -The `stages[]` array is the source of truth and `gatherCurrentNotes()` -re-syncs it from the DOM before any operation that needs current text. - ---- - -## 4. The badge — accurate state communication - -Top-right of the save bar. Exactly four states: - -| Condition | Text | Background | -|---|---|---| -| `_state.stages.length >= _state.stage` (current stage has been generated) | `Stage N` | Gray | -| `_state.stages.length < _state.stage` (advanced past last generation; no note for stage N yet) | `Stage N (recording)` | Yellow | -| `_state.finalized && !_state.mdm` (transient) | (not reached — finalize is atomic) | — | -| `_state.finalized` | `Finalized` | Green | - -This badge was the source of the most confusing UX bug in v1: clicking -"Add more" used to immediately flip the badge to "Stage 2" even though -no Stage 2 note existed yet. The fix isn't subtle — `updateBadge()` derives -the label from the relationship between `_state.stages.length` and -`_state.stage`, with explicit color coding so the difference is -unmistakable. - ---- - -## 5. Frontend file map - -### `public/components/ed-encounter.html` - -The static markup. Roughly: - -- **Save bar** (`#ed-save-bar`) — label input, badge (`#ed-stage-badge`), - Save draft / Load / New buttons, plus a Load popover for saved drafts. -- **Patient Info card** — age (`#ed-age`), gender (`#ed-gender`), chief - complaint (`#ed-cc`), and the model select (`#ed-model-select` with the - `tab-model-select` class). -- **Recording card** — header showing `Stage N - Recording / Dictation`, the Listen In / Pause buttons, the recording - indicator with timer, and a contenteditable transcript box (`#ed-transcript`). -- **Generate button** (`#btn-ed-generate`) — `Generate Stage N Note`. -- **`#ed-stages-container`** — empty div. JS appends one card per stage here. -- **`#ed-tail-controls`** — refine bar (textarea + Refine latest + Shorter) - + stage-control row (Add more, Save & Done). Hidden until at least one - stage exists. Hidden again after finalize (encounter is locked). -- **`#ed-mdm-card`** — the green-bordered MDM card. Hidden until finalize. - The blue-bordered "Final Consolidated Note" card is **created - dynamically** by `renderFinalNote()` and inserted before the MDM card. - -### `public/js/ed-encounters.js` - -Single IIFE module. Key functions: - -| Function | What it does | -|---|---| -| `freshState()` | Returns a clean `_state` object — used at module load and `resetEncounter()` | -| `gatherCurrentNotes()` | Walks the DOM stage cards (`#ed-stage-text-N` elements) and writes their current text back into `_state.stages[N].note`. Called before persist, advance, finalize, generate (the last because the AI prompt for stage N+1 needs the latest text of stage N as `previousNote`). | -| `persistLocal()` | Debounced 300ms localStorage save under key `ped_ed_draft_v1`. Snapshot includes `_state` plus the current label/age/gender/CC/transcript box content. | -| `loadLocal()` | Reverse of `persistLocal()` — restores state on tab open if a draft exists. | -| `renderStages()` | Rebuilds `#ed-stages-container` from `_state.stages[]`. Each card gets a unique id `ed-stage-text-N`. Cards become `contenteditable=false` after finalize. | -| `buildStageCard(idx, stage)` | Constructs one card's DOM. Includes the editable note + an embedded yellow "Don't Miss — Stage N" section if `stage.dontMiss` is non-empty. | -| `renderFinalNote(note)` | Lazily creates `#ed-final-note-card` (blue border) and inserts it before the MDM card. | -| `renderMdm(mdm)` | Fills `#ed-mdm-card` with structured MDM HTML (problems / data / risk paragraphs + suggested level + rationale + disclaimer). | -| `updateBadge()` | Sets `#ed-stage-badge` text + background color based on state. | -| `initRecording()` | Wires the record / pause buttons, browser SpeechRecognition, AudioRecorder, transcribe-on-stop. Identical pattern to `sickVisit.js` — copy-pasted because the recording paths are sacred and shouldn't be factored into a shared helper. | -| `generateStage()` | Validates inputs, calls `gatherCurrentNotes()`, fetches user templates via `getUserMemoryContext()`, POSTs `/api/ed-encounters/generate`, pushes the result into `_state.stages[stage-1]`, re-renders, autoSaves a draft to the DB. | -| `advanceStage()` | Validates current stage exists, gathers edits, increments `_state.stage`, clears the transcript box, updates the badge to "(recording)", scrolls to the recorder. **Does NOT touch any displayed cards.** | -| `finalize()` | Validates label + at least one stage, gathers edits, POSTs `/api/ed-encounters/finalize` with the full stages array, on success renders Final Note + MDM cards, marks finalized, calls `saveEncounter` with `status='final'`, clears localStorage. | -| `composeFinalNoteForSave(note, mdm)` | Concatenates the final note + MDM block into a single text blob written to `saved_encounters.generated_note` (so the saved encounter has a single coherent stored note for any downstream consumer). | -| `autoSaveDraft()` | Best-effort — saves a `status='draft'` row to `saved_encounters` if a label is set. Called after each stage generation. Silent if no label. | -| `resetEncounter()` | "New" button — wipes state, removes stage cards, hides Final Note + MDM, clears localStorage, drops the saved-encounter id. | -| `refineLatestStage()` / `shortenLatestStage()` | Resolve the latest stage's text element id (`stageTextElId(stages.length - 1)`) and call the global `refineDocument` / `shortenDocument` helpers from `app.js`. | - -### How the file integrates with `encounters.js` - -`public/js/encounters.js` is **sacred** (per the project memory file — -don't refactor without per-change approval, especially the save/idempotency -logic). ED encounters needed exactly two minimal touches to it: - -1. Line 98: `'ed'` added to the sessionStorage restore array so the - `_savedEncId_ed` value survives page refresh. -2. Lines 305-310: `ed: 'ed'` added to the `tabMap` in `resumeEncounter` so - the saved-encounters list can navigate to the ED tab when a user - clicks a saved ED row. - -That's it. Save logic, idempotency, optimistic versioning — all reused -unchanged via `window.saveEncounter()`. ED rows store with `enc_type='ed'` -and `partial_data` containing the full `{stages, finalNote, mdm, finalized}` -JSON for resume. - -A `registerEncounterLoadHandler('ed', fn)` call near the bottom of -`ed-encounters.js` registers the resume handler with `encounters.js`. When -a user clicks an ED row in the Load popover, `encounters.js` invokes that -handler with the decrypted row, and the handler restores `_state` and -re-renders. - ---- - -## 6.

Quality - over quantity. Tailored strictly to age + chief complaint. -- **PRESERVE INSTRUCTIONS WITHIN DICTATION** — explicit instruction that - physician asides like "include normal cardiac exam" or "assessment is - viral URI" are first-class clinical input. Route exam findings to PE, - assessment statements to A&P, plan statements to A&P. Never echo as - quoted speech. -- **Templates** — the user's templates (especially `template_ed`, but also - matching `template_hpi`/`template_soap`/`template_sickvisit`) are - delivered in the user message as PHYSICIAN TEMPLATES AND PREFERENCES. - Apply matching template sections; never copy clinical content from a - template — only formatting/structure. -- **Previous-stage note** — explicit instruction: integrate the new - transcript on top of the previous note, do not start fresh.

Resolve contradictions by using the later value AND - noting the change in ED Course (e.g., "now afebrile after antipyretic"). -- Preserve every clinical fact; never drop information; never invent. - -#### `edFinalize` - -System prompt for the MDM step. Returns strict JSON `{mdm: {...}}`. - -Includes a **full inline rubric** of the 2023 AMA E/M MDM table so the -model has clear definitions to score against: - -- **Element 1 — Problems addressed**: minimal / low / moderate / high - with explicit definitions (e.g., "high = chronic illness with severe - exacerbation, OR acute illness/injury that poses threat to life or - bodily function"). -- **Element 2 — Data reviewed**: categories (tests reviewed, tests - ordered, independent interpretation, discussion with another physician, - external records, independent historian) and counting rules for - minimal / limited / moderate / extensive. -- **Element 3 — Risk**: minimal / low / moderate / high with concrete - examples per level (drug therapy requiring intensive monitoring, - decision regarding hospitalization, etc.). -- **Level mapping** (2 of 3 elements must meet the level): 99281 through - 99285 with descriptions of the typical encounter at each level - (99284 = "MODERATE complexity MDM, most common ED visit with workup, - labs, or imaging and prescription decisions"; 99285 = "HIGH complexity - MDM, admission for high-acuity care"). - -Critical rules at the bottom: -- Use only information present in the note (and transcript if provided). -- Never invent. -- Conservative when ambiguous — pick the lower level. -- `levelRationale` must reference specific elements actually documented. - -This prompt is the most important to get right — it's what determines the -suggested billing level.

Persistence — three layers - -### Layer 1 — localStorage (`ped_ed_draft_v1`) - -Debounced 300ms after every input event.

Survives page refresh, browser restart, signing out + back in. - -Cleared on `resetEncounter()` and on successful finalize. - -This is the **fast** layer — captures every keystroke without round-trips. - -### Layer 2 — saved_encounters DB row, status='draft' - -Best-effort auto-save after each stage generation. Requires a label to be -set; silent no-op otherwise. Uses `window.saveEncounter` from -`encounters.js` with: - -- `enc_type: 'ed'` -- `status: 'draft'` -- `generated_note`: the latest stage's note (so the saved-encounters list - has something to preview) -- `partial_data`: encrypted JSON containing `{stages, finalized: false}` -- `idempotency_key: 'ed-draft-' + savedId` - -The same row gets updated on each subsequent generation (by passing -the saved id back to `saveEncounter`). - -This is the **durable** layer — survives device loss because it's on the -server, encrypted at rest with the app key. - -### Layer 3 — saved_encounters DB row, status='final' - -Written exactly once on successful finalize. Includes: - -- `generated_note`: the **final consolidated note + MDM block** combined - via `composeFinalNoteForSave()`, so any downstream consumer (export, - copy, print) gets a single coherent text. -- `partial_data`: `{stages, finalNote, mdm, finalized: true}` — full - fidelity for resume / audit / future re-render. -- `idempotency_key: 'ed-final-' + Date.now()` — unique per finalize - attempt so a network retry doesn't create a duplicate row. - -After finalize, localStorage is cleared. The encounter is locked from -further edits in-app (stage cards become `contenteditable=false`, tail -controls hidden). The user can still load the row later for review; -editing requires loading then unlocking by some manual workflow that -doesn't yet exist (TODO if requested). - ---- - -## 8. The "Don't Miss" tooltip — per-stage - -Each stage's response from `/api/ed-encounters/generate` includes a -`dontMiss[]` array of `{point, why}` objects. Same JSON call as the -note — no second AI request. The stage card embeds these as a -yellow/orange section beneath the note text: - -``` -┌─────────────────────────────────────────┐ -│ Stage 2 Note [model] [Copy] │ -├─────────────────────────────────────────┤ -│ Chief Complaint: ... │ -│ HPI: ... │ -│ ... │ -├─────────────────────────────────────────┤ ← yellow background -│ ⚠ Don't Miss — Stage 2 │ -│ • Document hydration status │ -│ (tachycardia + 4-day vomiting) │ -│ • Consider DKA workup │ -│ (polyuria + weight loss in HPI) │ -│ • ... │ -└─────────────────────────────────────────┘ -``` - -ED don't-miss is **uncapped** by design — Daniel wanted no limit ("just like -remember to ask this, do this, keep this in mind etc."). Compare with -`/api/dont-miss` (used by sick visit + encounter HPI) which caps at 5 -both in the prompt and via server-side `.slice(0, 5)`. - -The same-call design (note + don't-miss in one JSON) was a deliberate -choice to keep per-stage latency down. The risk (model occasionally -shortcuts the don't-miss list) is acceptable per Daniel since don't-miss -is informational, not load-bearing. - ---- - -## 9. Templates — `template_ed` - -When a physician saves a template under category `template_ed` -(Settings → Templates), it gets included in the `physicianMemories` string -that the frontend fetches via `getUserMemoryContext()` and passes to -`/api/ed-encounters/generate`. - -The flow: - -1. User saves a template named e.g. "ED Pearls" with category `template_ed`. -2. Server stores it in `user_memories` (encrypted name + content). -3. On next ED note generation, `ed-encounters.js` calls - `getUserMemoryContext()` (defined in `public/js/memories.js`). -4. That function fetches `/api/memories/context` which returns a single - string containing every active template (correction_* rows are - filtered out at the SQL level — the AI corrections feature was - removed in late April 2026). -5. The string is included in the user message under the - "PHYSICIAN TEMPLATES AND PREFERENCES" header. -6. The system prompt's "PHYSICIAN TEMPLATES" section instructs the model - to apply matching sections from any template (especially `template_ed`, - but also matching HPI/SOAP/sickvisit templates). - -`template_ed` was added to `VALID_CATEGORIES` in `src/routes/memories.js` -and to the dropdown in `public/components/settings.html`. - ---- - -## 10. Why the design looks like this - -Each major decision, with the constraint that motivated it. - -### Why per-stage cards (vs. one rolling note element) - -**Daniel's clarification.** The first build used one `#ed-note-text` -element that got replaced on each generation. After demo: "every stage -note should be shown, if AI is told to modify that particular note then -the modified version is used in final mdm." The cards model is the -direct response — every stage stays visible, every stage is editable, -edits flow into finalize. - -### Why the badge has an explicit "(recording)" state - -**Bug from first user test.** Clicking "Add more" used to flip the badge -to "Stage 2" immediately, before any Stage 2 note existed. Daniel: "the -title changes to stage 2 even without a new recording and generate being -hit." The fix isn't subtle — `updateBadge()` derives state from the -relationship between `stages.length` and `_state.stage`, with explicit -color coding so the difference is unmistakable. - -### Why finalize is two server-side AI calls instead of one - -**Quality concern.** A single combined "produce finalNote AND mdm in one -JSON" prompt makes the model cut corners on one of the two tasks -(usually the MDM rubric gets compressed). Two focused calls each get -their own dedicated system prompt with no competing pressure. Cost: ~2x -latency at finalize. Justification: finalize is a one-time terminal -action, not a per-stage hot path. - -### Why edConsolidate returns plain text instead of JSON - -**Reliability + simplicity.** The consolidate step produces ONE thing — -a clinical note. JSON wrapping adds parse-failure surface area for zero -benefit. The text is rendered directly into a `contenteditable` element. -The MDM step does need JSON because it has structured fields the UI -displays in a table layout. - -### Why the MDM prompt has the full 2023 AMA rubric inline - -**Daniel's directive: "make sure mdm is configured well."** Models' -training data includes pre-2023 guidelines mixed with 2023; relying on -"you know the AMA E/M MDM table" produces drift. The prompt now -includes element-by-element definitions (problems / data / risk), -counting rules for data, and concrete examples per level. The level -rationale must reference specific findings. - -### Why the recorder code is copy-pasted from sickVisit.js - -**Project memory: "Voice/STT is sacred — Don't refactor recorder/transcribe -plumbing; fix only named bugs in smallest diff."** The recording paths -in every clinical tab look almost identical; refactoring to a shared -helper is a textbook clean-code move that has burned this project before -(silent breakage of recording when the abstraction ate an edge case). -The deliberate non-DRY duplication is the safer choice. - -### Why finalize sends the whole stages array instead of just stage texts - -The consolidate prompt benefits from seeing each stage's transcript -(physician's actual dictation) AND each stage's note (which may include -physician edits). The transcripts let the AI catch facts that didn't -make it into the working notes; the notes show physician interpretation. -Both together produce a more faithful consolidation. - -### Why `previousNote` is sent during stage 2+ generation, not just the transcript - -The per-stage AI is told to "integrate the new transcript on top of the -previous note as baseline, do not start fresh." Without the previous -note as input, stage 2 would have to regenerate everything from -transcripts alone (slower, less faithful to physician edits made between -stages). - ---- - -## 11. Sacred / fragile zones - -These are not refactor-without-permission lines. - -### `public/js/encounters.js` - -Per project memory: don't touch without per-change approval; even -pre-approved changes get rejected if they refactor save/idempotency. The -ED feature touched it in exactly two places (sessionStorage array and -tabMap) and that's it. **All ED save/load goes through `window.saveEncounter` -and `registerEncounterLoadHandler` — established interfaces. Do not -add new methods to encounters.js or modify the save body shape.** - -### Recorder + transcribe paths - -`public/js/audioBackup.js` (the AudioRecorder class), the -`transcribeAudio` global function, the SpeechRecognition wrapper from -`public/js/speechRecognition.js`. The ED tab's recording logic in -`initRecording()` was copied from `sickVisit.js` deliberately. Don't -factor it out into a shared `record-and-transcribe-helper.js`. - -### The MDM prompt rubric - -The 2023 AMA E/M element definitions and level mapping in -`PROMPTS.edFinalize` are load-bearing for billing accuracy. Don't trim -them to "save tokens" — the cost of a miscoded encounter to a real -practice is much higher than the prompt overhead. Update only with -explicit billing/coding source citation. - ---- - -## 12. How to extend — concrete recipes - -### Add a new prompt key - -1. Add the entry to `PROMPTS` in `src/utils/prompts.js`. Use the same - `${CORE_RULES}` and (if relevant) `${ROS_PE_RULES}` preambles other - prompts use. -2. The DB-override system (`loadFromDb` in the same file) auto-picks up - the new key on next startup, so admins can override it from the - Admin → Prompts UI without code changes. - -### Tweak the MDM rubric - -Edit `PROMPTS.edFinalize` in `src/utils/prompts.js`. Cite the source -(2023 AMA E/M Office or Other Outpatient guideline updates, or AMA -errata) in the commit message. The rubric structure is stable — -changes are usually wording refinements, not category rewrites. - -### Add a new field to the stage card (e.g., timestamp) - -1. The data is already in `_state.stages[i].generatedAt`. -2. In `buildStageCard(idx, stage)` in `public/js/ed-encounters.js`, - add a small `
` next to the model tag in the card header. -3. No backend change needed; `generatedAt` is already saved in - `partial_data`. - -### Add per-stage refine (instead of "refine latest") - -1. In `buildStageCard()`, render a refine input + button for every - stage card. -2. Update the refine button click handler to read `data-stage-idx` from - the clicked button and pass `stageTextElId(idx)` to `refineDocument`. -3. Be aware: physicians editing earlier stages then refining them then - regenerating later stages creates a complex causality chain. Daniel's - current call is "refine targets the latest stage" to avoid this. - -### Add a new ED-specific output (e.g., a discharge instructions card) - -1. Decide if it's per-stage or once-per-encounter. Per-encounter is - simpler — generate it on finalize. -2. Add a third server-side AI call in `/api/ed-encounters/finalize` - between consolidate and MDM. Add the result to the response payload. -3. Add a new card to `ed-encounter.html` (or create dynamically like - `renderFinalNote`). -4. Render it in the finalize success handler. - -### Unlock a finalized encounter for editing (TODO — not implemented) - -Currently no UI for this. Would require: - -1. A new endpoint `POST /api/ed-encounters/:id/unlock` that flips - `status` from `'final'` back to `'draft'` and clears `partial_data.finalized`. -2. An "Unlock for editing" button on the load popover for finalized - rows. -3. UI logic in `ed-encounters.js` to handle the unlocked state - (re-enable editing on stage cards, re-show tail controls). - -### Add a fourth stage type (currently the prompt is generic) - -The current design treats all stages identically — same prompt, same -structure. If there's a value in distinguishing "initial assessment" -vs "post-workup" vs "post-consult" stages with different prompts, that's -a meaningful shift. Probable plan: - -1. Add a `stageType` field to each stage entry. -2. Branch on `stageType` in the route to pick a prompt variant. -3. UI: dropdown next to the recorder that defaults to "Initial / - Workup / Consult / Disposition" based on stage number. - -This isn't currently planned — the generic stage works because the -physician's dictation is what differentiates stages, not a metadata tag. - ---- - -## 13. Testing pointers - -There are currently **no Playwright e2e tests** for ED encounters — flagged -as TODO in the session that built the feature. A reasonable first batch: - -1. **Stage 1 happy path.** Open tab, fill label/age/gender/CC, type - transcript, click Generate, assert Stage 1 card appears with note - text and don't-miss section. -2. **Multi-stage flow.** Stage 1 → Add more → badge says "Stage 2 - (recording)" with yellow background → type Stage 2 transcript → - Generate → both Stage 1 and Stage 2 cards visible. -3. **Edit-then-finalize.** Generate Stage 1 → edit the note text inline - → Save & Done → assert the consolidate step received the edited text - (mock `/api/ed-encounters/finalize`, inspect the request body). -4. **Finalize renders both cards.** Mock `/finalize` to return - `{finalNote, mdm}` → assert blue Final Note card AND green MDM card - appear → assert stage cards become read-only. -5. **Resume from saved.** Save a draft, reload, click Load, pick the - ED row → all stages reappear with their don't-miss sections. - -The mocking pattern is in `e2e/fixtures.js` — `mockAI(page, overrides)`. -Add `'**/api/ed-encounters/generate'` and `'**/api/ed-encounters/finalize'` -to the routes table with canned responses. - ---- - -## 14. Known issues / TODOs - -- No e2e coverage (above). -- No "unlock" UI for finalized encounters. -- The MDM-step partial-success case (consolidate succeeded, MDM failed) - returns 502 with `finalNote` in the error payload, but the client - doesn't render the partial result. Currently the user sees a generic - error toast and loses the consolidate work. -- Per-stage refine isn't supported — only "refine latest." If the user - wants to refine an earlier stage, they edit it inline (works) but - don't get an AI-assisted refine for that specific stage. -- The "(recording)" badge color (yellow) might be confusing in the - dark theme if one is added — currently the app is light-only. -- The consolidate step uses the configured default model unless the - user picks a specific one in the dropdown. There's no way to use one - model for per-stage generation and a different model for finalize. - Probably fine; flag if a user wants this. -- `extractJson` is defined locally in `src/routes/edEncounters.js` and - duplicated from `notes.js`. Candidate for `src/utils/jsonRecover.js` - if a third route ever needs it. - ---- - -## 15.
