Patient Satisfaction Surveys: What to Ask, When to Send, and How to Act (2026)

90% of satisfaction surveys at LATAM clinics are useless. They're too long, sent too late, ask generic questions, and nobody analyzes the results. A survey that doesn't generate action is noise, not information.

This article teaches you how to design surveys that actually help improve your clinic.

Why most surveys fail

Mistake	Consequence
20-question survey	Response rate under 5%
Sending by email in LATAM	Nobody opens it (open rate under 10%)
Generic questions	Generic answers that don't inform action
Sending a week later	Patient no longer remembers details
Not analyzing results	Data accumulates with nobody reviewing it
Not closing the loop	Patient feels their opinion didn't matter

The 10 questions that actually generate action

The 3 essentials (always send)

1. NPS: "On a scale of 0-10, how likely are you to recommend us?" → Your main loyalty metric.

2. Open question: "What could we improve?" → Qualitative information that explains the number.

3. Critical attribute: "How would you rate your wait time? (1-5)" → Attacks the most common pain point.

The 7 optional (rotate as needed)

4. "Was it easy to schedule your appointment?" (1-5) 5. "Was the reception staff friendly and efficient?" (1-5) 6. "Did the physician clearly explain your diagnosis and treatment?" (1-5) 7. "Did you receive your results in a reasonable time?" (1-5) 8. "Were the facilities clean and comfortable?" (1-5) 9. "Would you return for care with us?" (Yes/No) 10. "What additional service would you like us to offer?" (Open)

Golden rule: Maximum 5 questions per survey. Rotate the optional ones monthly to cover different aspects without tiring the patient.

When to send the survey

Timing	Response rate	Response quality
Immediately upon leaving	10-15%	⚠️ Rushed
2 hours later	20-30%	✅ Reflective and recent
Next day	15-20%	✅ Good
1 week later	5-10%	❌ Details forgotten
Monthly (batch)	3-5%	❌ Not linked to experience

The sweet spot: 2 hours after the visit, via WhatsApp.

Why WhatsApp wins in LATAM

Channel	Open rate	Response rate	Cost
Email	15-20%	3-5%	$0.01/send
SMS	90%	10-15%	$0.05/send
WhatsApp	95-98%	20-30%	$0.03/send
Phone call	40%	25-35%	$0.50/call

WhatsApp combines SMS open rates with email response richness, at minimal cost.

How to turn responses into improvements

Step 1: Automatically classify

Score	Action
NPS 9-10 (Promoter)	Thank + request Google review + invite to referral program
NPS 7-8 (Passive)	Thank + ask what's missing to reach 10
NPS 0-6 (Detractor)	Alert to manager + personal contact within 24h

Step 2: Weekly theme analysis

Group open responses by theme each week:

How many mention wait time?
How many mention staff treatment?
How many mention scheduling?

The most frequent theme is your improvement priority.

Step 3: Close the loop

The patient who gave feedback must know they were heard:

Detractors: personal contact + solution
Promoters: thank you + review invitation
Passives: thank you message + improvement implemented

Example automated flow with Davix

Patient finishes visit → system records departure time
2 hours later → WhatsApp sends automatic survey (3 questions)
Patient responds → data recorded in commercial management
If NPS 0-6 → automatic alert to manager
If NPS 9-10 → automatic Google review link sent
Weekly dashboard → NPS by physician, specialty, location

Frequently asked questions

Should every patient receive a survey?

Ideally yes, but if your volume is very high, you can sample (1 in 3). What matters is that the sample is representative.

Can I send surveys to lab/imaging patients?

Yes, and you should. Adapt the questions: instead of "wait time at consultation," ask about "results delivery time."

What if NPS is low and not improving?

Review open responses to identify patterns. If the problem is structural (waits due to physician shortage, infrastructure), the survey confirms what you already suspect and gives you data to justify investment.

How often should I review results?

Aggregate results: weekly. Detractor alerts: daily (response within 24 hours).

Conclusion

Satisfaction surveys are powerful when well-designed:

Maximum 5 questions — less is more.
Send via WhatsApp 2 hours post-visit — best timing and channel.
NPS + open question — the minimum essentials.
Act on results — especially with detractors (under 24h).
Close the loop — the patient must know they were heard.
