National Accreditation Board for Hospitals & Healthcare Providers (NABH)‘s Digital Health Standard for Hospitals has eight chapters. The first chapter, Access, Assessment and Continuity of Care (AAC) carries more Objective Elements than any of them: 40, against a chapter average closer to 23.

Most hospitals assume AAC is the easy chapter, because “we already have a reception desk.” AAC is not asking whether a front desk exists. It is asking whether that front desk runs on a digital system, end to end.

Read the standard yourself. NABH’s Digital Health Standard for Hospitals is available in full, free, at nabh.co/digital-health-standards — creating a free NABH account is required to access it. Nothing in this piece substitutes for the source document itself.

Recommended starting point: This piece is from a series on the NABH Digital Health Standard for Hospitals and assumes familiarity with many fundamental terms such as Chapters, Standards, Objective Elements, the four bands, and tier requirements. If these terms are new to you, it may make more sense to start from the beginning.

A note on ordering: within each standard below, Objective Elements are grouped by band — Core first, then Commitment, then Achievement, then Excellence — rather than listed alphabetically by letter. This makes each standard’s actual weight easier to read at a glance, but it does mean the lettering runs out of sequence in places. The letter itself is unchanged from the standard; only the reading order is regrouped.

AAC.1 — Digital Information and Display Requirements

AAC.1 requires the hospital to use a digital system to educate and disseminate information to the public and patients, across four Objective Elements. None are Core.

Core

None under AAC.1.

Commitment

• AAC.1.a. General and educational information (Commitment) — hospital operating hours, contact details, doctor profiles, services, and patient education material, shared via website, mobile app, or listings with healthcare aggregators. A 40-bed hospital’s front desk, for example, would satisfy this by publishing OPD timings and consultant profiles on its own website rather than only quoting them over the phone.
• AAC.1.b. Digital display of accreditations (Commitment) — NABH, NABL, ISO, and similar affiliations shown on the hospital’s website or app, not just on a lobby wall.

Achievement

• AAC.1.d. In-facility digital displays (Achievement) — consultant availability, room numbers, and token numbers shown on screens inside the hospital, replacing a receptionist calling out names or a handwritten whiteboard in the waiting area.

Excellence

• AAC.1.c. Informative notifications to patients — appointment reminders, medication alerts, test results, and camp or scheme announcements, sent via WhatsApp, SMS, or email — for example, an automated WhatsApp message telling a diabetic patient their HbA1c report is ready, instead of the patient calling to check.

Two of AAC.1’s four elements — (a) and (b) — are Commitment-band, meaning they count toward the 60% Commitment threshold every tier, including Silver, requires.

AAC.2 — Digital Patient Registration and Referral

AAC.2 is where AAC’s weight concentrates: nine Objective Elements, and two of AAC’s three Core elements.

Core

• AAC.2.b. A unique hospital ID for every new patient — assigned with or without an ABHA account, so every patient’s records can be reliably retrieved. In practice, this could be built from an Aadhaar number, a mobile number, a government photo ID, or demographic details in combination.
• AAC.2.g. Linking all patient records — pharmacy, lab, radiology, every touchpoint — to one unique patient ID — so a nurse pulling up a patient’s file sees every department’s records under a single ID, not four separate systems that each recognise the patient differently under a different ID.

Commitment

• AAC.2.a. At least one digital registration system — kiosk (reception), website, mobile app, QR code, or ABDM’s “Scan and Share” feature.
• AAC.2.d. Duplicate-entry detection — flagging likely duplicate patient records using identifiers like name, date of birth, or mobile number, so the same patient doesn’t end up with two unlinked histories.
• AAC.2.f. A unique transaction number for every repeat visit — linked to the same patient ID, so a patient’s third visit this year is still traceable back to their first five years ago.

Achievement

• AAC.2.c. ABHA generation and capture, linked to the patient’s unique identifier — including support for patients without phones, so ABHA enrollment doesn’t stall at the one step that assumes everyone owns a smartphone.
• AAC.2.i. Digital second-opinion referral management across specialties — for instance, an oncology patient’s case routed digitally to a second specialist, with urgency flagged, instead of a printed referral letter handed to the patient to deliver themselves.

Excellence

• AAC.2.e. Offline-mode record creation, synchronised once the system is back online — so a network outage or power cut doesn’t stop registration at the front desk.
• AAC.2.h. Cross-facility record access for other hospital entities, branches, or affiliates, typically via a Master Patient Index (MPI) — relevant for any hospital that is part of a chain or has a diagnostic or pharmacy affiliate under the same group.

Two of AAC’s three Core elements — (b) and (g) — sit inside AAC.2. Together they describe a single requirement in two parts: every patient gets one identity, and every record generated anywhere in the hospital links back to it.

AAC.3 — Digital Appointments and Practitioner Schedules

AAC.3 requires a digital system to manage patient appointments and the schedules of treating medical practitioners, across six Objective Elements. None are Core.

Core

None under AAC.3.

Commitment

• AAC.3.a. Digital appointment booking — patients book or cancel via website, mobile app, kiosk, or the registration desk itself, rather than only by phone. The NABH frames this as reducing staff workload and improving accessibility, since patients can act at any hour instead of only during a call-center window.
• AAC.3.f. Digital reminders for upcoming and follow-up appointments — auto-generated SMS, WhatsApp, or email, so a patient doesn’t rely on memory alone for a follow-up scheduled weeks out. A 60-bed hospital running six OPD specialties, for instance, would need this to fire automatically across every specialty’s calendar, not just the ones a receptionist remembers to call.

Achievement

• AAC.3.c. Digital access to the treating practitioner’s profile while booking — credentials, specialisation, and patient ratings visible before a patient commits to an appointment, not just a name and a time slot.
• AAC.3.d. Booking with a specific named practitioner — so a patient can see the same doctor across follow-up visits, which the standard ties directly to continuity of care rather than whichever consultant happens to be free.
• AAC.3.e. Practitioners viewing their own appointment schedules digitally — via message, email, or in-app alert, so a doctor can prepare for specific procedures in advance and avoid double-booking a slot.

Excellence

• AAC.3.b. Interoperability with external booking platforms via UHI — if a patient books through a third-party healthcare aggregator, that booking has to sync automatically with the hospital’s own HIMS/EMR through the Unified Health Interface (UHI), a system designed to connect otherwise-separate health information systems onto one interoperable layer.

AAC.4 — Digital Lab Test Orders and Samples

AAC.4 covers the laboratory, and carries AAC’s third Core element.

Core

• AAC.4.a. A unique, patient-linked sample ID for every sample collected — using a barcode scanner and label printing or an equivalent digital method, so every blood draw or specimen is traceable back to the specific patient it came from. This is the same “one identity, fully linked” logic as AAC.2’s Core elements, applied to physical samples instead of registration records.

Commitment

• AAC.4.b. Digital tracking of sample movement and turnaround time — from collection through transfer to the lab, so staff can see where a sample is and prioritise urgent tests instead of chasing a phlebotomist by phone.
• AAC.4.d. Digital access to lab reports for OPD patients — via a website or mobile app, with a notification sent once a report is ready, rather than requiring a return visit just to collect a printed result.

Achievement

• AAC.4.e. Digital records of outsourced lab tests and their results — when a hospital sends a sample to an external laboratory, the results still need to be captured and stored digitally, not filed as a separate paper report that lives outside the patient’s main record.

Excellence

• AAC.4.c. Auto-populated lab results via LMIS integration — laboratory analysers connected directly to the Laboratory Management Information System, so results upload automatically instead of being manually keyed in from a printout, cutting both turnaround time and transcription error.
• AAC.4.f. Lab reports linked to the patient’s ABHA account — part of a longitudinal health record that persists beyond a single hospital visit, so a report from this admission is visible the next time the patient is treated anywhere else.

AAC.5 — Digital Radiology Test Orders and Images

AAC.5 mirrors AAC.4’s logic for radiology, across five Objective Elements. None are Core.

Core

None under AAC.5.

Commitment

• AAC.5.a. A unique ID for every radiological test or procedure, linked to the patient’s identifier — ensuring the right patient is matched to the right scan, the same principle as AAC.4.a applied to imaging instead of samples.
• AAC.5.b. A RIS/PACS system for the radiology department — a Radiology Information System and Picture Archiving and Communication System that manages and stores X-rays, CT scans, and MRIs alongside patient data, and is used to create, finalize, and issue reports rather than relying on a radiologist dictating findings onto paper.

Achievement

• AAC.5.c. Digital access to radiology reports for patients — via a patient portal or secure email, without requiring a physical trip to collect a film or a printed report.
• AAC.5.e. Digital records of outsourced radiology tests and results — the same requirement as AAC.4.e, applied to scans sent to an external radiology center rather than performed in-house.

Excellence

• AAC.5.d. Radiology reports and full images linked to ABHA, in an interoperable format — so a referring practitioner elsewhere can pull the actual scan, not just a text summary of the findings.

AAC.6 — Digital Patient Admissions

AAC.6 is AAC’s smallest standard by Objective Element count, but not by the information it requires. Both elements are Commitment-band.

Core

None under AAC.6.

Commitment

• AAC.6.a. A digital admission form capturing all admission-related information — patient demographics, preliminary diagnosis, medical history, care plan, date of admission, expected date of discharge, package details, and payor details, entered once digitally rather than duplicated across several paper forms at registration, nursing, and billing.
• AAC.6.b. Digital ward and bed assignment and tracking — assigning a patient to a specific ward and bed, and tracking that assignment digitally, so bed availability and patient location are visible in real time rather than tracked on a physical whiteboard that only the floor nurse can update.

Achievement

None under AAC.6.

Excellence

None under AAC.6.

AAC.7 — Digital Discharge and Transfer Process

AAC.7 covers the other end of the inpatient stay, across six Objective Elements — three Commitment, three Achievement, none Core or Excellence.

Core

None under AAC.7.

Commitment

• AAC.7.a. A digital system for the primary treating practitioner to request and update discharge information — via an EHR or HMIS system, with secure messaging to coordinate across billing, food and beverage, and nursing as the discharge plan gets finalised.
• AAC.7.b. Digital notification of discharge to internal departments — admissions, ward nursing, lab, pharmacy, and billing all notified digitally when a patient is cleared for discharge, rather than relying on a phone call or a runner walking between departments.
• AAC.7.c. Digital billing clearance for discharge — the billing department clears a patient digitally, ideally with pathology, radiology, and medicine records auto-fetched into the bill via HMIS integration, rather than the discharge stalling for hours on a manual bill reconciliation.

Achievement

• AAC.7.d. A digital, structured discharge summary the practitioner can generate — built by selecting relevant sections from different clinical modules, then sent to the patient via secure email or uploaded to a patient portal.
• AAC.7.e. The discharge summary linked to the patient’s ABHA address — part of their longitudinal health record, so a future provider can see this admission’s diagnosis and outcome without the patient having to carry a physical folder.
• AAC.7.f. Digital management of inter-departmental patient transfers — for example, OT to post-operative recovery, recovery to a ward, or emergency to a ward — including handover documentation and the expected time of handover, so the receiving team has the patient’s condition and treatment plan before the patient physically arrives.

Excellence

None under AAC.7.

AAC.8 — Digital Patient Feedback and Complaints

AAC’s final standard is its shortest, but it is where a hospital learns whether AAC.1 through AAC.7 are actually working.

Core

None under AAC.8.

Commitment

• AAC.8.a. Digital collection of patient and family feedback — through a dedicated feedback module, online surveys, a digital suggestion box, social media, review sites, or even chatbots and automated messaging, so feedback isn’t limited to a paper form handed out at the exit.

Achievement

• AAC.8.b. Digital segregation and analysis of feedback by touchpoint — appointments, hospital stay, and post-treatment follow-up analyzed separately, so a hospital can trace a specific complaint (long appointment wait times, for example) back to the touchpoint actually causing it, instead of reading all feedback as one undifferentiated stream.

Excellence

None under AAC.8.

The Self-Check

Before assuming AAC is “basically covered,” a hospital should map its front desk and clinical-support operations against these questions:

1. Can a patient register, or pre-register, through a digital channel — not just at a physical counter?
2. Does every patient get one digital ID that every department’s records link back to?
3. Can the hospital generate and capture an ABHA number as part of registration?
4. Do lab samples carry a digital, patient-linked ID from collection to result?
5. Are admission, discharge, and billing-clearance steps run through a digital system, or coordinated by phone and paper handoff?

A hospital answering “no” to more than one or two of these is likely underestimating how much of AAC.1 through AAC.8 is still manual.

Why AAC Is Not Optional, Even at Silver

AAC has only 3 Core Objective Elements out of 182 across the entire standard — a small fraction on paper. But Silver-tier eligibility requires 100% of Core plus 60% of Commitment, and AAC alone carries 17 of the standard’s 57 Commitment elements — the largest Commitment concentration of any chapter. A hospital cannot reach Silver while treating AAC as a chapter to revisit later; a majority of its Commitment elements have to be in place from the first assessment.

This is the same reason operational excellence for Indian hospitals increasingly runs through front-desk and registration systems rather than around them — AAC is where a hospital’s digital maturity is judged from the moment a patient walks in, which is the same instinct behind understanding why a system works at a structural level rather than just clearing the nearest bar.

FAQ

How many Objective Elements does the AAC chapter have in NABH’s Digital Health Standard for Hospitals?

40 — more than any other chapter, out of 182 total across the standard.

What are AAC’s Core (mandatory) Objective Elements?

Three: a unique hospital ID for every patient (AAC.2.b), linking all patient records to that ID (AAC.2.g), and a unique, patient-linked sample ID for laboratory samples (AAC.4.a).

Does AAC require ABHA integration?

Yes, in multiple places — ABHA generation and capture during registration (AAC.2.c), and ABHA-linked lab reports, radiology reports, and discharge summaries at the Achievement or Excellence band, depending on the standard.

The Decision

The question AAC actually asks isn’t whether a hospital has a reception desk, a lab, and a discharge process — every hospital does. It’s whether those processes run on a digital system that generates one identity per patient and links every downstream record to it, or whether that link still lives in a filing cabinet and a receptionist’s memory.
