Which channels produced treated patients, not consultations?

Before a vein practice can treat truncal reflux and be paid for it, most payers require a documented trial of conservative therapy — commonly six weeks to three months of graduated compression — plus a duplex study meeting specific reflux and diameter thresholds, plus prior authorisation.

This is not a soft sales cycle that varies with how persuasive the practice is. It is a fixed, external gate, and it means first enquiry to first collected dollar reliably runs three to seven months, with a full bilateral episode taking longer still.

That makes every standard attribution window structurally wrong in this speciality. Reconciling collected episode revenue against the enquiry history is the only approach that is unaffected by the gate, because it does not depend on a window at all.

Spider vein sclerotherapy is cosmetic, cash, and marketed on appearance. Truncal ablation is medical, billed to insurance, and marketed on symptoms — aching, swelling, heaviness. The two attract different searches at very different costs per click and produce revenue an order of magnitude apart.

Blended into one report they produce an average that describes neither, and they drag each other's apparent performance in opposite directions. A service-line column separates them so each can be funded against its own economics.

Between the charge posted on the day of service and the money in the account sit the contractual adjustment, the patient responsibility, and often a denial and an appeal. A report built on charges overstates every channel, and overstates them unevenly depending on payer mix.

Exporting collections by service date keeps the total reconcilable to the practice's own financials. On a page whose argument is that the numbers are defensible, a marketing report that disagrees with the practice management system by forty per cent is worse than no report at all.

Community screening days, employer health fairs and free ultrasound evenings are a staple of this segment, and they are expensive in a way that is easy to underestimate: staff time, equipment, a venue, printed material and the clinical hours spent scanning people who turn out to need nothing. Attendance is counted carefully because it is easy to count. What almost never happens is anybody going back six months later to ask how much treatment those attendees actually went on to have.

This leaves a peculiar asymmetry in the practice. The search campaign is scrutinised on a cost-per-enquiry basis every month, while an event costing several thousand pounds a time is assessed on whether the room looked full. Both are acquisition spending and only one of them is being held to a standard, which tends to mean events continue by momentum long after their productive years and paid media gets cut whenever a quarter looks tight. Nobody decided that; it is simply what happens when one line of spending has a dashboard and the other has a sign-in sheet.

An attendee list is an enquiry file. Export the names and contact details captured on the day, list the event as a source, and it is ranked on collected treatment revenue beside every paid channel. Clinics doing this for the first time commonly find the events are either far better or far worse than assumed and rarely in between, and that the variation between individual events is wider than the variation between events and advertising as categories. That last finding is the useful one, because it turns a decision about whether to run events at all into a decision about which events to keep.

Venous disease is progressive and treatment is frequently staged. A patient treated on one leg returns for the other; a patient treated years ago returns with recurrence; a patient who had a medically indicated procedure comes back later for the cosmetic finishing work that was never covered. Each of those is a separate revenue event and each of them traces to the same person, who first found the clinic through something a marketing budget paid for at some point in the past.

Practices rarely credit any of it. The second and third episodes appear in the accounts as new cases with no obvious source, so they fall into whatever passes for an unattributed bucket and the original campaign is assessed on the first procedure alone. Over several years that understatement compounds, and it compounds most for the oldest and best sources — precisely the campaigns a practice would want to protect if it knew what they had produced. By the time anybody thinks to ask, the campaign that produced the patient has been switched off for two years and nobody can defend it.

Running the report across a long enough window credits every subsequent episode to the enquiry that produced the patient. Marking recurrence and staged work with a column keeps them visible as their own line, so the clinic can see both new-patient acquisition and the returning revenue behind it rather than one blended total. The history needed for that already exists, because these records were kept to bill the work rather than to measure anything. Nothing had to be installed at the time, which is what makes a five-year look-back a report rather than a project.
