Patient-reported outcomes: from paper to light

Every week, thousands of patients fill out questionnaires in waiting rooms: pain, mobility, sleep, mood. And every week, most of those sheets end up in a filing cabinet — data that cost patient and staff time, and never sees the light again.

What is a patient-reported outcome?

A PRO is any measurement of health status that comes directly from the patient, without clinician interpretation: how much pain they feel, how far they can walk, how they sleep, how their energy is. It's measured with validated instruments — ODI for spine, KOOS for knee, PROMIS for fatigue and physical function — that turn subjective experience into numbers comparable over time.

The problem isn't collection — it's what happens after

Paper collection fails at three points: patients stop answering once the visit is over (6-month response rates fall below 20%), hand-entering the sheets consumes assistant hours, and captured data is rarely charted — so it never informs a clinical decision.

Data nobody sees changes no treatment. A filed-away PRO is the patient's wasted work.

What changes when follow-up is automatic

When the questionnaire arrives on WhatsApp by itself at the right points of the clinical schedule — 2 weeks, 6 weeks, 3 months, 1 year — and the answers chart themselves, three things change: response rates rise (patients answer from home, in minutes), the physician sees each patient's real trajectory and the whole cohort's, and the data is research-ready.

That is exactly what Salumbra does: validated questionnaires over WhatsApp, on autopilot, turned into clear evidence of how each patient is doing. No paper, no manual entry, no IT department.
