How to measure new-patient inquiry conversion

Start with one definition

Most measurement attempts fail on definition rather than tooling. Decide, in writing, what counts as a new-patient inquiry: a first-time caller, a form submission, a text, a booking. Existing patients and suppliers do not count.

A definition that is slightly imperfect but applied consistently is far more useful than a precise one applied intermittently.

Count in two columns

For each week, record the number of new-patient inquiries and how many became a scheduled appointment. That ratio is your conversion rate.

A shared spreadsheet is enough to start. Resist adding attribution, source, provider and treatment type in week one — complexity is the main reason these logs are abandoned.

Watch the gap, not the number

A single month's rate tells you little. Four to six weeks of consistent counting shows you a range, and the interesting question becomes what the bad weeks had in common.

Commonly it is not demand. It is a day when calls went unanswered, or a batch of inquiries nobody followed up.

Then split by source

Once the total is stable, split it. An insurance directory and a referral rarely convert at the same rate, and marketing decisions look different once you can see that.
