Patient Recall Campaigns: Bringing Lapsed Patients Back

Every hospital has a database of patients who visited once and never came back. Some left because their treatment was complete. Others moved to another provider. Many simply drifted — life got busy, they felt better, and re-booking never happened.

Recall campaigns target this lapsed group with structured outreach tied to clinically logical re-engagement triggers. A diabetic patient who hasn't been seen in 90 days is due for a review. A post-op patient who hasn't had a follow-up in 6 months needs a prompt. An annual health check patient who came 13 months ago is overdue.

Why Recall Outperforms New Patient Acquisition

The economics of patient recall are considerably better than new patient acquisition:

| Metric | New Patient | Recalled Patient | |--------|------------|-----------------| | Acquisition cost | ₹800–₹3,000+ | ₹30–₹80 per message | | Conversion rate | 2–8% | 25–45% | | Average spend per visit | ₹700–₹1,200 | ₹1,000–₹2,500 (follow-ups include diagnostics) | | No-show rate | 25–35% | 12–18% |

Lapsed patients already know your hospital. They've been through your process. They're not evaluating you against competitors — they're deciding whether to act on the reminder. That's a much shorter sales cycle.

Segmenting Your Recall List

Not all lapsed patients should receive the same message. Segment by:

Condition-based recall:

• Diabetes: 90-day recall for HbA1c review
• Hypertension: 90-day recall for BP monitoring
• Arthritis: 120-day recall
• Post-surgical follow-up: 30, 90, 180-day recalls

Last visit date:

• 60–90 days lapsed: warm re-engagement, no urgency
• 90–180 days lapsed: gentle prompt with a specific reason
• 180+ days lapsed: stronger offer (health camp, free screening)

Department:

• OPD regular patients: appointment reminder with doctor name
• Diagnostic-only patients: invite for annual health check
• Emergency admissions: follow-up care with appropriate sensitivity

Compliant Messaging Under NMC and TRAI

Patient recall messages are promotional communications under TRAI's framework, which means they require explicit prior consent and a clear opt-out mechanism.

Consent is best captured at registration: "I agree to receive health reminders and appointment notifications from [Hospital] via WhatsApp and SMS." This must be affirmative (not pre-ticked).

Every recall message must include an opt-out: "Reply STOP to unsubscribe."

NMC guidelines permit recall messages that are clinically appropriate and educational. "Your annual diabetes review is due — book a slot with Dr. Sharma" is compliant. "Visit us this month for a special discount on check-ups" is not.

Message Templates That Work

Condition-based recall (90-day diabetic review):

"Hi [Name], it's been 3 months since your last visit with Dr. [Doctor] for diabetes management. Your quarterly review is due. Book a slot: [Link]. Reply STOP to unsubscribe."

Annual health check:

"[Name], your annual health check with [Hospital] is due. Catch issues before they escalate. Book your screening now: [Link]. Reply STOP to opt out."

Post-surgical follow-up:

"Hi [Name], Dr. [Doctor] would like to check on your recovery from your [Procedure] last [Month]. Please book a follow-up at your earliest convenience: [Link]."

Timing and Cadence

Send recall messages at 10–11 AM or 6–7 PM — times when patients are likely to be checking their phones but not in the middle of work or sleep.

For a single lapsed patient, a maximum of 2 recall attempts per quarter is appropriate. If both go unanswered, add them to a dormant list and re-engage in 6 months.

Don't batch all recall messages on a Monday morning — your call centre will be overwhelmed. Spread sends across the week so incoming booking requests are manageable.

Measuring Recall Campaign Success

Track these metrics per campaign:

• Delivery rate: Were messages delivered to active numbers?
• Click rate: Did patients click the booking link?
• Conversion rate: Of those who clicked, how many booked?
• Show rate: Of those who booked via recall, how many showed up?
• Revenue per campaign: Average consultation + diagnostic spend per recalled patient

A well-run recall campaign for a 50-doctor hospital typically generates ₹3–₹8 lakh per month in re-engaged revenue that would otherwise be lost.
