Outpatient Appointment Reminders via SMS, Text & WhatsApp
Your outpatient clinic sees 2,400 appointments a week. Without reminders, 18% of them are no-shows, 432 empty slots the clinic paid staff to cover. Three-touch SMS, text and WhatsApp reminders drop that to 4%, recovering 336 appointments a week of actual patient care.
The DNA rate that blocks real treatment
Your hospital outpatient did-not-attend (DNA) rates cost national health systems and private clinics a fortune every year. Every empty slot is a patient somewhere else who couldn’t get booked. Every DNA is also a scheduling inefficiency, the staff member was there, the room was booked, the consultant was ready, and nobody turned up.
Your DNAs aren’t patients dodging the appointment. They’re patients who forgot, moved the date in their head, got the time mixed up, or didn’t realise they needed to confirm. A proper reminder sequence addresses all four.
The three-touch reminder sequence
Your Salesforce Appointment record fires reminders on a scheduled Flow:
- T-7 days, WhatsApp: “Your appointment with Dr. Patel is Tuesday 14 May at 10am, Clinic 3. Reply YES to confirm, CHANGE to reschedule.”
- T-1 day, SMS: “Reminder, appointment tomorrow 10am, Clinic 3. Bring your ID and any recent test results.”
- T-2 hours, WhatsApp: “See you at 10am today. Free parking at Level 2 of the multistorey. Appointment may run 45 minutes.”
Your messages references the specific consultant, the specific clinic location, the specific time. Patients feel expected and prepared. Clinics fill the seats they planned to fill.
Rescheduling that doesn’t require a phone call
Your Patient replies “CHANGE” or “can’t make Tuesday, Thursday?” Your Agentforce AI agent checks Dr. Patel’s Salesforce calendar for Thursday availability, offers two slots, confirms whichever the patient picks, and updates the Appointment record. Your booking team never sees the reschedule.
Your patient wants a date the consultant isn’t available, your AI offers the next nearest slots and explains why. If the patient needs a specific test beforehand, the AI flags the dependency and routes to the booking team. Escalation happens only when the AI can’t resolve, which on a typical week is maybe 5% of reschedules.
Pre-appointment preparation messages
Your appointments need preparation, fasting before a blood test, stopping specific medications before a procedure, bringing recent scans. Your Salesforce Appointment Type record holds the preparation rules. The reminder sequence includes the relevant prep instructions in the T-1 day message.
Your patients arrive prepared. Your clinic doesn’t waste a 30-minute slot on someone who ate breakfast before a fasting test. Your consultant sees the patient they expected to see, ready to be treated.
What the hospital admin sees on Monday morning
Your every appointment status, confirmed, rescheduled, DNA, attended, logs to the Salesforce Appointment record. Your reports show DNA rate by consultant, by clinic, by appointment type, by day of week, by patient demographic. Your scheduling team uses the patterns to tighten double-booking policies and adjust capacity.
Your automation doesn’t just reduce DNAs. It turns your scheduling from a reactive guessing game into a measured, optimised process that gets better every month.
