Cost per admission is the only number that settles an argument
Every other metric is a proxy. Impressions are a proxy for reach, clicks for interest, calls for intent. Cost per admission is the thing itself, and it is the only figure that can be compared against what an admission is worth to the program.
That comparison needs a number marketing does not own. Average revenue per episode of care, by level of care and by payer, comes from billing. average revenue per admission by level of care — pull from finance and verify with Tim Once it exists, every channel decision becomes arithmetic instead of opinion.
The second half of the calculation is the payback window. A residential admission that bills over 30 days is a different cash problem than an outpatient patient who bills over six months, even at the same margin.
Why healthcare attribution breaks
Most healthcare conversions happen on the phone, and phones are invisible to analytics by default. The research window is long, so a first click in March can produce an admission in May. People switch devices between the two. And the person searching is often not the person being treated.
Privacy rules cut the other way too. OCR's guidance on online tracking technologies restricted how HIPAA-covered entities may use analytics and ad pixels where the data could identify an individual and relate to their health. Part of that guidance, as applied to unauthenticated public webpages, was vacated by a federal court in Texas in June 2024. The safe posture did not change: send nothing to an ad platform that ties a person to a condition.
The workaround is server-side and offline. Attribute the call, record the outcome in your own system, and send back only a conversion event and a value, without patient detail.
The three connections
First, call tracking with dynamic number insertion, so a call from a paid click, an organic visit, and the Google Business Profile carry different numbers. This is where most accounts stop, and it is only the first third.
Second, the CRM. Whatever the call becomes, that outcome has to be written next to the source. In practice this means a source field on the record, populated automatically rather than typed by whoever answered, and a status field the admissions team keeps current.
Third, offline conversion import. Google Ads accepts conversions uploaded after the fact with a value attached, which lets the bidding algorithm bid toward admissions instead of form fills. Skip it and you are paying a bidding system to chase the wrong outcome.
What a report should contain
Spend, calls, qualified calls, admissions, and cost per admission, broken out by channel and campaign, with the previous period next to it. Five columns. If a report is longer than that and does not contain those five, it was written to look like work.
Ask for call recordings alongside the numbers. Listening to ten calls tells you more about a campaign than a month of dashboards, and it is the fastest way to find out that half your paid calls are job applicants or vendors.
Rankings belong in a diagnostic appendix, not on the first page. A number one position on a term nobody searches is not a result.
Where ROI math misleads
Branded search takes credit for demand other channels created. It looks like the best-performing campaign in every account because it is the last click before the call. Judge it separately from everything else.
Small numbers lie. A program admitting typical monthly admissions for a two-location client — confirm with Tim patients a month cannot resolve a 10% difference between two campaigns in a single month. Look at quarters, and be honest when a change is inside the noise.
And a low cost per admission on a channel that cannot scale is not a strategy. Directory listings and referrals are often the cheapest source in the building and the least expandable.
