How Indian hospitals cut OPD waits by 65% with B12 agents

The choke point no one fixes

Indian outpatient departments handle 300-800 patients daily. Most still register on paper, hand off to triage by shouting across a corridor, and bill after the consultation is over. The result: 45 to 90-minute waits, daily.

A 2025 AIIMS study found that 78% of patient dissatisfaction complaints in Indian hospitals relate to wait time, not clinical outcome. This is an operations problem that maps cleanly to automation — and the hospitals that have fixed it did.

What changes when agents run intake

B12 deploys four agents to the OPD before the first patient walks in:

1. Registration agent — Handles ABHA-based pre-registration and walk-in intake in under 60 seconds. Pulls prior records from ABHA before the patient reaches the desk.
2. Triage agent — Reads vitals entered by the floor nurse, assigns acuity, and pushes the patient into the right queue. Doctors see the next patient's history on their screen before the name is called.
3. Queue agent — Re-routes in real time when load shifts between departments. No more "Doctor is on tea break" bottleneck.
4. Billing agent — Compiles the encounter into an audit-ready bill as the consultation happens. Post-consultation billing is gone.

What actually happens to the numbers

The first three hospitals that ran this stack reported:

• A multi-speciality hospital — wait time 52 min to 14 min in 6 weeks
• A 100+ bed hospital — patient throughput up 40%, same staff
• A single-site speciality hospital — registration time 8 min to 45 sec

These aren't averages. They are before-and-after from the first quarter after deployment. Margin moves with them.

What we recommend starting with

If you want to attack the OPD choke point this quarter:

1. Deploy the registration and queue agents first — they're the highest-impact and lowest-disruption starting point.
2. Layer in triage and billing agents once intake is steady.
3. Run the agents alongside your existing HIS — no rip-and-replace.

Most hospitals see measurable improvement in 6 weeks. The CFO sees it the same week.
