Vitrify Clinic Score
Every clinic page carries a Vitrify Clinic Score. It grades how much this directory knows about a clinic and how well that knowledge is evidenced. It does not measure the quality of that clinic’s care.
The three measures, and which page carries which
| Measure | About | Question it answers | Where it appears |
|---|---|---|---|
| Vitrify Score | A doctor | How much is known about this clinician, and how well evidenced? | Doctor profiles |
| Vitrify Clinic Score | A clinic | How much is known about this clinic, and how well evidenced? | Clinic profiles |
| Listing completeness | A clinic listing | How much has been published on this listing? Counted, never graded. | Clinic profiles |
The clinic pages carry the second and third together because they answer different questions. Completeness counts whether a fact is present; the Clinic Score grades how much there is and how well corroborated. Neither is a rating.
The six factors
| Factor | Weight | What it reads |
|---|---|---|
| Registry standing | 20 | How long the clinic has held an ART registration, saturating at 25 years, together with whether the registration number and the issuing authority are recorded. Computable for every clinic from the registry extract alone. |
| Contactability | 25 | How many of a phone number, an email address and a website a patient can actually use to reach the clinic. |
| Self-description | 15 | Whether the clinic publishes a description of itself of at least 200 characters, and whether it publishes any social profile. |
| Treatment breadth | 15 | How many distinct treatments are recorded against the clinic, saturating at eight. |
| Clinical team declared | 15 | How many doctors are declared at the clinic, saturating at six. |
| Evidence strength | 10 | How many independent sources corroborate the record, saturating at four. Not computed where the registry extract is the only source, because that is a fact about our looking rather than about the clinic. |
What is deliberately not a factor
ART level is not scored. The registry states whether a clinic is licensed at Level 1 (IUI and work-up) or Level 2 (licensed for IVF and ICSI on site). Scoring Level 2 above Level 1 would say that an IVF-licensed clinic is a better clinic, which is a judgement about clinical scope rather than about the clinic — a patient who needs IUI is not better served by a Level 2 centre. The level is shown on every clinic page as a fact and carries no weight here.
Accreditations are not scored. This directory holds no accreditation data of any kind: there is no NABH, NABL or JCI record in it.
Reviews are not scored. No review has been published in this directory yet. When they are, whether they belong in this measure will be decided then rather than assumed now.
A factor that cannot be checked leaves the total
When a factor cannot be computed it is dropped, and it takes its weight out of the total with it. A clinic we have only seen in the registry extract is scored out of 20, not marked down out of 100. Absence is never scored as zero.
Four of the six factors can only be answered by looking beyond the registry — reading the clinic’s own website and corroborating it. They share one cause and therefore one fate: either all four were checked, or none were. Where they were checked and the clinic publishes nothing, that is a finding and they score zero. Where nobody has looked, they are dropped and the card says so in words.
The distinction between “we looked and there is none” and “nobody has looked” is the one this whole design turns on. On a clinic page a checked factor with nothing in it reads 0 out of 15 with a solid empty bar; an unchecked factor reads Not checked with a dashed one. They are never drawn alike.
The score is never rescaled
A partial score is reported out of the weight that was actually available, and is never converted to a percentage of 100. Rescaling would put a one-factor and a six-factor measurement on the same axis, and it distorts in both directions depending on an arbitrary choice: counting an unchecked factor as zero drives every unchecked clinic into a narrow band at the bottom, and dropping it instead floats them upward until a clinic nobody has looked at outranks one we checked in full. Reporting earned out of available removes the choice. It is also why the ring is not a full circle for every clinic.
When it was computed
A score is computed and stored, not derived when the page loads. Each clinic page states how many of the six factors went into its score and names the ones that did not. As more of the directory is checked, scores are recomputed and the number of factors behind them rises.
