Patient Case-Taking Software

Description: Background: 1.1 The Clinical History-Taking Bottleneck in Indian Hospitals History taking - the structured elicitation of a patient's presenting complaints, history of present illness, past medical and surgical history, drug and allergy history, family and personal history, and a review of systems - is the single most important diagnostic activity in clinical medicine. Classical teaching holds that a well-conducted history yields the correct diagnosis in 70–80% of cases, even before examination or investigation. Yet in India's overburdened public hospital outpatient departments (OPDs), the time available for this critical interaction has collapsed to unsustainable levels. India operates one of the most patient-dense healthcare systems in the world. Tertiary government hospitals and apex institutions routinely register 4,000–10,000 OPD patients per day, with a doctor-to-patient consultation time frequently reported between 2 and 5 minutes - among the shortest globally (study published in BMJ Open, 2017, across 67 countries placed India's average primary-care consultation at just over 2 minutes). Within this window, the physician must simultaneously elicit history, examine the patient, review prior records, formulate a diagnosis, counsel, and prescribe. The result is systematic under-elicitation of history, missed comorbidities, repeated questioning across visits, and diagnostic error. AYUSH institutions face an additional layer of complexity. Ayurvedic history taking (Trividha, Ashtavidha, and Dashavidha Pariksha) requires detailed assessment of Prakriti (constitution), Vikriti (current imbalance), Agni (digestive capacity), Koshtha (bowel nature), Ahara-Vihara (diet and lifestyle), Nidana (causative factors), and Samprapti (pathogenesis) - a far more extensive history framework than allopathic intake. Capturing this depth manually within OPD time constraints is effectively impossible, forcing practitioners to abbreviate the very assessment that defines personalized Ayurvedic care. 1.2 The Documentation and Records Fragmentation Problem Compounding the time problem is the fragmentation of patient records. Patients in India typically carry physical paper prescriptions, laboratory reports, discharge summaries, and imaging films from multiple prior providers. During consultation, the physician must manually scan through these unstructured documents - often handwritten, in varying languages, and chronologically disordered - consuming a significant fraction of the already-scarce consultation time. There is no point-of-entry mechanism to digitize, structure, and chronologically organize a patient's prior medical documents before they reach the consultation room. The Ayushman Bharat Digital Mission (ABDM) has established the national digital health infrastructure - ABHA (Ayushman Bharat Health Account) IDs, the Health Information Exchange, and FHIR-based interoperability standards. However, the 'first-mile' problem remains unsolved: there is no efficient, patient-facing software platform that captures structured history and digitizes documents into the ABDM ecosystem before the clinical encounter begins. 1.3 The Opportunity: AI-Powered Digital Clinical Intake Platform Self-service kiosks have transformed high-throughput service industries - ATMs in banking, self-check-in terminals in aviation, and ordering kiosks in quick-service restaurants - by offloading structured data-entry tasks from human staff to the user, dramatically improving throughput and accuracy. In healthcare, patient check-in kiosks are now widespread in developed-country hospitals, but these are limited to administrative check-in. None perform deep, AI-driven, multimodal clinical history acquisition with medical document digitization. The convergence of mature enabling technologies - robust automatic speech recognition (ASR) for Indian languages and accents (Bhashini / AI4Bharat models), large language models for conversational clinical history elicitation, high-accuracy OCR for handwritten and printed medical documents, and ABDM's FHIR interoperability - now makes it feasible to build an AI-powered clinical history software platform. Description: 2.1 The Problem in Precise Terms There is no purpose-built, patient-facing software platform that enables patients to independently and comprehensively record their medical history - through both natural spoken conversation and guided touchscreen interaction - and simultaneously digitize their existing physical medical documents, generating a structured, physician-ready clinical history summary that integrates with the hospital information system and the ABDM ecosystem before the patient enters the consultation room. 2.2 Why Existing Solutions Fall Short • Existing hospital registration systems (currently deployed in some Indian hospitals) capture only demographic and appointment data - name, age, department, token number. They do not elicit any clinical history or process medical documents. • Mobile health apps and tele-triage chatbots require smartphone literacy, stable connectivity, and patient enrolment ahead of the visit - excluding the large elderly, rural, low-literacy, and first-visit patient populations who form the bulk of government hospital OPD load. • Manual nurse-led triage / history desks are themselves human-resource-limited, do not scale to 5,000+ daily patients, and reintroduce the same time and transcription bottleneck the system is trying to eliminate. • Generic document scanners digitize images but do not extract, structure, or chronologically organize clinical content, nor link it to a structured history or ABHA record. 2.3 Specific Challenges a Solution Must Overcome • Multilingual, multi-accent voice capture in noisy hospital environments across Hindi, English, and major regional languages, for patients of varying literacy and digital comfort. • Accessibility for low-literacy and elderly users through intuitive icon-driven UI, audio prompts, and conversational guidance - the software platform must be usable by a first-time, non-tech-savvy patient with zero training. • Accurate clinical history structuring converting free-form patient narration into a standardized, physician-readable history (chief complaint, HPI, past history, drug/allergy, family, personal, review of systems) - and, for AYUSH settings, Dashavidha Pariksha parameters. • Reliable medical document digitization OCR of handwritten and printed prescriptions, lab reports, and discharge summaries in multiple languages, with intelligent extraction of diagnoses, medications, and investigation values. • Privacy, consent, and data security compliance with the Digital Personal Data Protection Act 2023 and ABDM consent framework - handling sensitive health data within a secure software environment. Expected solution: 3.1 Solution Overview - 'MediKiosk' AI Clinical History Software Platform The proposed solution - tentatively designated MediKiosk - a software platform for an AI-powered clinical history software platform that allows any patient to record a comprehensive medical history through natural voice conversation and guided touchscreen interaction, scan and digitize their existing physical medical documents, and generate a structured, physician-ready clinical history summary that is pushed to the hospital information system (HIS) and linked to the patient's ABHA record - all completed before the consultation, with minimal staff assistance required. • Insert Table*3.2 3.3 Software & AI Stack (Integrated) Module A - Conversational Multimodal History Engine A conversational AI engine that conducts a structured clinical history interview through both voice and touch. The patient speaks naturally in their preferred language; the engine asks intelligent follow-up questions (e.g., on stating 'chest pain', it probes onset, character, radiation, aggravating/relieving factors - the SOCRATES framework) and simultaneously offers touch-based multiple-choice options for patients who prefer tapping. Built on Indian-language ASR, a dialogue manager constrained by a clinical history ontology, and text-to-speech for audio prompts. • Adaptive questioning: dynamically branches based on chief complaint and prior answers, mirroring a physician's clinical reasoning to elicit a complete HPI and review of systems • Dual-mode input: every question answerable by speaking OR tapping, ensuring usability across literacy and comfort levels • AYUSH history mode: for Ayurvedic OPDs, an extended interview capturing Dashavidha Pariksha (Prakriti, Vikriti, Sara, Samhanana, Pramana, Satmya, Sattva, Ahara Shakti, Vyayama Shakti, Vaya) and Ahara-Vihara assessment • Red-flag detection: AI flags emergency symptoms (e.g., acute chest pain with dyspnoea, stroke symptoms) and triggers immediate priority alert to triage staff rather than routine queueing Module B - Medical Document Digitization & Intelligence An integrated scanning and document-AI pipeline that allows the patient to upload prior prescriptions, lab reports, and discharge summaries. The system performs high-accuracy OCR (printed and handwritten, multilingual), then extract and structure clinical entities. • Intelligent extraction: diagnoses, prescribed medications with dosages, investigation results with values and reference ranges, and procedure/surgery history • Chronological organization: automatically dates and orders documents into a coherent medical timeline for the physician • Abnormal-value highlighting: flags out-of-range lab values and potential drug interactions for physician attention Module C - Structured History Summary Generator An AI summarization engine that synthesizes the conversational history and the digitized documents into a single, concise, physician-ready clinical summary in standard format - presented on the consultation screen the moment the patient enters the room. The physician reads a complete, structured history in seconds rather than spending minutes eliciting it, and can edit/confirm before saving. • Standard clinical format: Chief complaint ? HPI ? Past medical/surgical ? Drug & allergy ? Family ? Personal ? ROS ? Prior investigations summary • Editable & verifiable: physician retains full control - the summary is a draft to accept, amend, or reject, never an autonomous diagnosis • Bilingual output: patient-facing audio confirmation in local language; physician-facing summary in English/Hindi Module D - Consent, Privacy & ABDM Integration A robust consent and security layer compliant with the Digital Personal Data Protection Act 2023 and the ABDM consent framework. The patient authenticates via ABHA ID, grants explicit consent for data capture and sharing, and the structured history is pushed to the hospital HIS/EMR and linked to the ABHA Personal Health Record via FHIR APIs. • Secure processing: voice and document AI are processed securely within the software platform • Session termination: temporary session data is cleared immediately after submission • Consent-first design: granular, revocable consent with audio explanation for low-literacy patients 3.4 End-to-End Patient Journey • Step 1 - Identify: Patient logs into the software platform, enters/scans ABHA ID or Aadhaar details or registers as new; selects language; grants consent (audio-guided) • Step 2 - Converse: AI conducts adaptive voice + touch history interview, capturing chief complaint, HPI, and full history; red flags trigger priority triage • Step 3 - Scan: Patient uploads prior prescriptions, lab reports, and discharge summaries; AI digitizes, structures, and timelines them • Step 4 - Summarize & Route: AI generates structured history summary, links to ABHA, pushes to HIS, updates the patient's digital record; summary appears on physician's screen at consultation • Step 5 - Consult: Physician reviews complete history in seconds, edits/confirms, and devotes the full consultation to examination, reasoning, and counselling

1. Executive Snapshot

Summary

The Indian healthcare system suffers from extreme outpatient department (OPD) congestion in government tertiary centers, registering 4,000 to 10,000 patients daily [PS]. This high volume restricts doctor-patient consultation times to an average of 2 to 5 minutes [PS] (with primary care consultations averaging ~2 minutes as documented in BMJ Open 2017) [RESEARCHED]. Within this brief window, clinicians must take a comprehensive history, conduct physical examinations, review scattered physical records, and formulate diagnostic and treatment plans [PS]. The problem is compounded in Ayurvedic institutions (such as the All India Institute of Ayurveda), where clinical history requires extensive assessment across Trividha, Ashtavidha, and Dashavidha Pariksha frameworks [PS]. Furthermore, historical patient data remains trapped in unstructured, handwritten paper records [PS].

MediKiosk is a multimodal, multilingual, patient-facing digital intake and document digitization software platform designed to run on self-service hospital kiosks and tablets [PS]. Using Indian-language Automatic Speech Recognition (ASR via Bhashini/AI4Bharat), a constrained clinical dialogue engine, high-accuracy handwritten medical OCR, and ABDM FHIR R4 interoperability, MediKiosk captures structured medical histories and digitizes prior paper records before the patient enters the consultation room [PS]. This transforms unstructured intake into a physician-ready clinical summary, restoring the consultation room for examination and clinical reasoning [PS].

5. Constraints & Environment Realities

  1. Acoustic Environment (60–80 dB Noise): Government hospital OPD waiting halls are extremely loud due to thousands of shouting patients, public address announcements, and crowd movement [INFERENCE]. Microphones without directional beamforming or noise-cancellation hardware will produce high Word Error Rates (WER) [INFERENCE].
  2. Connectivity & Network Latency: Public hospital Wi-Fi and mobile networks in India experience severe congestion and frequent dropouts [KNOWN]. The platform must operate with local edge fallback and robust retry queues rather than depending on uninterrupted high-bandwidth cloud connections [INFERENCE].
  3. Digital Literacy & User Cognition: Over 60% of public hospital OPD attendees in rural/semi-urban India have low text literacy or high digital apprehension [INFERENCE]. The UI cannot present dense text screens, drop-down menus, or complex navigation [PS].
  4. Hardware Hygiene & Throughput: Touchscreens in public OPDs face hundreds of interactions hourly [INFERENCE]. Physical terminals require ruggedized, washdown-capable IP65 front glass, non-mechanical physical document feed slots, or overhead camera scanners [INFERENCE].
  5. Operating System & Hardware Cost Constraints: Hospitals cannot deploy high-end GPU workstations at every registration desk [INFERENCE]. The software stack must run on affordable industrial Android/Linux kiosks or mini-PCs (e.g., Intel NUC or ARM SBCs) with central server offloading [INFERENCE].
  6. Linguistic Diversity: A single OPD in a major metro or national apex institute (like AIIA Delhi) sees patients speaking Hindi, Punjabi, Bengali, Bhojpuri, Haryanvi, and South Indian languages [KNOWN].

6. Research Questions

  1. What is the baseline Word Error Rate (WER) of Bhashini/IndicASR models in an 70 dB ambient noise background when capturing Indian medical terms?
  2. What is the real-world extraction accuracy of open-source vision-language models (e.g., Florence-2, Donut, TrOCR) on handwritten Indian doctor prescriptions compared to commercial Vision APIs?
  3. How do NRCeS FHIR R4 profiles structure dual-coded diagnostic information combining NAMASTE (National Ayush Morbidity Codes) and ICD-11 TM2 / Biomedicine?
  4. What specific latency threshold (seconds per screen) causes low-literacy elderly patients to abandon a self-service medical intake session?
  5. What hardware configuration (directional array microphone vs handheld push-to-talk handset) yields the highest audio signal-to-noise ratio in hospital registration queues?

+-------------------+--------------------------------+-----------------------+-----------------------+

Approach 1: Pure Rule-Based Touchscreen Kiosk

  • Mechanism: Static, decision-tree driven touchscreen interface with pre-translated audio prompts.
  • Pros: Highly predictable; runs on low-cost hardware; 100% offline; zero clinical hallucination risk [INFERENCE].
  • Cons: Rigid interaction; cannot handle free-form spoken chief complaints; fails for patients unable to navigate menus [INFERENCE].
  • Feasibility: High for hackathon, but fails explicit PS requirement for natural voice conversation [PS].

Approach 2: Pure Generative LLM Voice Agent (Cloud-First)

  • Mechanism: End-to-end cloud voice pipeline streaming audio to Whisper/Bhashini and passing transcripts to an unconstrained LLM (e.g., GPT-4o / Claude) for diagnostic dialogue.
  • Pros: Highly conversational; natural language understanding [INFERENCE].
  • Cons: High latency over hospital Wi-Fi; expensive API costs; risk of clinical hallucination or off-topic dialogue loops; high risk of failing during peak network outages [INFERENCE].
  • Feasibility: Vulnerable to network dropouts and hallucination risks in clinical triage [INFERENCE].

Approach 3: Hybrid Multimodal Architecture (Constrained Dialogue Manager + Edge OCR + Bhashini ASR/TTS) -- RECOMMENDED

  • Mechanism: A hybrid system utilizing local edge processing for touch UI and state management, Bhashini streaming ASR/TTS for regional Indian voice processing, a deterministic Finite State Machine (FSM) guardrailing a lightweight Clinical Micro-LLM for history extraction, and an edge-optimized Vision OCR pipeline.
  • Pros: Combines natural voice flexibility with strict clinical guardrails; dual-mode voice/touch redundancy; robust offline local fallback for touch intake; zero hallucination on critical red-flag rules [INFERENCE].
  • Cons: Requires careful software integration between state machine and voice engine [INFERENCE].
  • Feasibility: Optimal balance for hackathon demonstration and production deployment [INFERENCE].

10. Recommended Approach & Why

The Hybrid Multimodal Architecture (Approach 3) is selected [INFERENCE].

Justification

  1. Compliance with Explicit PS Requirements: Fully satisfies voice + touch duality (REQ-08), Indian language ASR (REQ-05), and low-literacy audio guidance (REQ-06) [PS].
  2. Clinical Safety & Zero Hallucination: By anchoring the dialogue engine to a deterministic Finite State Machine (FSM) constrained by standard SOCRATES and Dashavidha decision trees, the system eliminates LLM hallucination risks during critical triage [INFERENCE].
  3. Resilience to Hospital Realities: If cloud network connectivity fluctuates, the kiosk gracefully degrades to local touchscreen + pre-recorded voice prompt mode without shutting down intake [INFERENCE].

Why Alternatives Were Rejected

  • Approach 1 (Static Touch Kiosk) was rejected because it violates explicit requirements for natural voice interaction and conversational SOCRATES symptom probing [PS].
  • Approach 2 (Pure Cloud LLM Voice Agent) was rejected due to high network vulnerability, latency spikes in crowded hospitals, high API operating costs, and unacceptable clinical hallucination risks during red-flag detection [INFERENCE].

End-to-End Data Flow Narrative

  1. Step 1: Patient Authentication & Consent (Identify):
    • Patient approaches kiosk, taps screen or speaks. Audio prompt plays in selected language.
    • Patient enters ABHA ID / Aadhaar number or scans ABHA QR code. System verifies via ABDM M1 API.
    • Kiosk plays audio-guided DPDP consent explanation; patient taps "Agree" or speaks confirmation.
  2. Step 2: Conversational Multimodal Intake (Converse):
    • Kiosk asks chief complaint in selected language (e.g., "Aapko kya takleef hai?").
    • Patient speaks naturally or selects icon. Audio is captured, filtered via WebRTC VAD/Noise cancellation, and streamed to Bhashini ASR.
    • Text intent is passed to FSM Dialogue Manager. If chief complaint is "Chest Pain", SOCRATES protocol activates (asking onset, radiation, intensity).
    • Parallel AYUSH intake executes if in Ayurvedic OPD (capturing Agni, Koshtha, Prakriti markers).
    • Red-Flag Engine continuously scans responses. If acute emergency symptoms (e.g., chest pain radiating to arm with dyspnea) are detected, an immediate priority alert bypasses the queue and notifies nursing staff.
  3. Step 3: Document Upload & Intelligence Processing (Scan):
    • Patient feeds physical paper records (prescriptions, lab reports) into scanner slot.
    • Document AI pipeline executes OCR (PaddleOCR for printed, TrOCR fine-tuned for handwritten notes).
    • Medical NER identifies diagnoses, medications, and lab values, matching them against LOINC and reference ranges. Out-of-range values and drug interaction risks are flagged.
  4. Step 4: Summary Synthesis & ABDM/HIS Routing (Summarize & Route):
    • Summarizer Engine synthesizes conversational history and OCR entities into a dual-format JSON payload.
    • Generator emits: (a) Local language audio summary played to patient for verbal confirmation; (b) Standard English/Hindi clinical draft mapped into an NRCeS FHIR R4 OPConsultRecord Bundle.
    • Payload is pushed over secure ABDM Gateway to hospital HIS and linked to patient's ABHA account.
    • Kiosk purges all ephemeral session data from memory and prints/displays consultation queue token.
  5. Step 5: Physician Review & Consultation (Consult):
    • Patient enters consultation room. Physician screen automatically displays structured intake summary upon token selection.
    • Physician reviews structured HPI, Dashavidha parameters, digitized timeline, flagged lab outliers, and drug warnings in <15 seconds.
    • Physician edits/confirms draft, adds physical exam notes, and saves directly to HIS/EMR.

Detailed AI Component Analysis

1. Bhashini Speech Recognition (ASR)

  • Purpose: Converts spoken patient responses into structured text transcripts across Indian languages [PS].
  • Model Type: IndicConformer / Streaming ASR [RESEARCHED].
  • Input: Raw PCM audio stream (16kHz) from kiosk microphone array.
  • Output: Local language text string with confidence scores.
  • Why AI: Rule-based audio matching cannot handle unpredictable speech patterns, multi-accent variations, or free-form narration [INFERENCE].
  • Evaluation: Word Error Rate (WER) and Character Error Rate (CER) target <15% in 65 dB noise background [INFERENCE].
  • Failure Mode & Human Oversight: If ASR confidence drops below 0.60, kiosk automatically switches UI to icon-driven touchscreen selection mode [INFERENCE].

2. Clinical History Dialogue Engine & FSM

  • Purpose: Dynamically probes symptoms using SOCRATES and Dashavidha frameworks [PS].
  • Model Type: Finite-State Machine (FSM) guardrailed by a quantized Intent Classification Model [INFERENCE].
  • Input: Patient transcript text + current conversation state.
  • Output: Next structured question + voice prompt ID + UI option buttons.
  • Why AI: Static questionnaires are rigid, whereas intent-driven FSM permits natural language answers while retaining deterministic diagnostic pathways [INFERENCE].
  • Evaluation: Intent classification F1 score > 0.90; zero invalid state transitions.
  • Failure Mode: If intent is unrecognized, system plays audio clarification prompt: "Did you mean pain started today or earlier?" with on-screen touch buttons [INFERENCE].

3. Medical Document Intelligence (OCR + NER)

  • Purpose: Extracts diagnoses, drugs, dosages, and lab test values from paper records [PS].
  • Model Type: PaddleOCR (printed) + TrOCR Transformer (handwritten) + BioBERT/Clinical NER [RESEARCHED].
  • Input: High-resolution document image scan (300 DPI).
  • Output: Chronologically organized JSON schema containing mapped drugs (RxNorm/SNOMED) and lab values (LOINC).
  • Why AI: Rule-based template matching fails across heterogeneous, non-standard handwritten Indian prescriptions [INFERENCE].
  • Evaluation: Precision/Recall on clinical entity extraction > 85%.
  • Failure Mode: Low-confidence OCR extractions are displayed in yellow on physician dashboard with original image side-by-side for manual verification [INFERENCE].

4. Structured Clinical Summarizer & Red-Flag Classifier

  • Purpose: Synthesizes intake history into standard HPI summary and flags emergencies [PS].
  • Model Type: Med-Gemma-2B / Llama-3-8B Fine-Tuned + Regex Emergency Filter [INFERENCE].
  • Input: Full interview transcript + parsed OCR JSON payload.
  • Output: Structured draft clinical summary + Red-Flag triage priority tag.
  • Why AI: Summarizing unstructured dialogue into standard clinical headers requires natural language generation [INFERENCE].
  • Evaluation: ROUGE-L score against expert clinician summaries; 0% false negatives on critical red-flag rules.
  • Failure Mode: Physician retains 100% edit control. System presents summary as a draft requiring explicit click-to-confirm [PS].

Where AI MUST NOT Be Used

  1. Red-Flag Emergency Priority Logic: Initial triage detection must utilize deterministic keyword/regex threshold rules (e.g., "chest pain" AND "shortness of breath") rather than probabilistic LLM outputs to guarantee zero non-deterministic triage drops [INFERENCE].
  2. ABHA Authentication & OTP Verification: Cryptographic identity verification must execute strictly through deterministic security protocols [PS].
  3. FHIR R4 Bundle Validation: Mappings to NRCeS FHIR schemas must follow strict deterministic serialization to prevent invalid API payload rejections [RESEARCHED].

15. Security, Privacy & Governance

  1. Digital Personal Data Protection (DPDP) Act 2023 Compliance:
    • Data Minimization: Kiosk collects only data necessary for the upcoming clinical encounter [PS].
    • Explicit Audio Consent: Low-literacy patients receive audio explanations of data usage before intake begins [PS].
    • Ephemeral Session Purge: Immediate wiping of voice recordings, temporary document scans, and PII memory buffer as soon as session completes or timeouts occur [PS].
  2. ABDM Consent Framework & Identity Security:
    • Patient authentication via ABHA ID / Aadhaar OTP or demographic validation [PS].
    • OAuth 2.0 authorization tokens utilized for all ABDM Gateway API requests [RESEARCHED].
  3. Data Encryption & Cryptographic Safeguards:
    • In Transit: Mandatory TLS 1.3 encryption for all internal server-kiosk communications [INFERENCE].
    • At Rest: AES-256 bit encryption applied to any temporary disk buffer on the kiosk or hospital server [INFERENCE].
  4. Access Control & Governance:
    • Role-Based Access Control (RBAC) ensuring only authenticated attending OPD physicians assigned to the patient's queue can view clinical summaries [INFERENCE].
  5. Medical Liability Disclaimer:
    • Software explicitly operates as a draft intake assistant, never providing autonomous clinical diagnoses [PS].
    • Physician screen explicitly requires human verification and acceptance before saving to the official EMR [PS].

Scripted Demo Journey (3 Minutes)

  1. Act 1: Multimodal Intake & Emergency Triage (60s):
    • Presenter interacts with Kiosk UI in Hindi. Taps "Start Intake", scans sample ABHA QR code.
    • Kiosk plays audio prompt. Presenter speaks: "Mujhe do din se seene me tez dard hai aur saans phool rahi hai" (Chest pain & dyspnea).
    • System extracts intent, triggers SOCRATES follow-up, detects Emergency Red-Flag, interrupts queue, displays priority alert, and sends instant alert notification to Nursing Dashboard.
  2. Act 2: AYUSH Intake & Document Scanning (60s):
    • Reset session with standard Ayurvedic OPD scenario. Complete Dashavidha Pariksha questions via voice/tap.
    • Feed a sample handwritten prescription image into the document scanner module. Live OCR parses handwritten drugs (Tab. Augmentin, Syp. Zandu Trishun) and lab values (Blood Sugar: 240 mg/dL), automatically highlighting the out-of-range glucose.
  3. Act 3: Summary Synthesis & Physician Verification (60s):
    • System generates bilingual output: plays local language summary audio for patient and renders formatted English clinical summary on Physician Dashboard.
    • Show valid NRCeS FHIR R4 OPConsultRecord JSON payload ready for ABDM synchronization.
