What an ABHA number is worth without a record behind it
Identity coverage and record substance are two different numbers, and only one of them gets reported.
India has built the identity layer of a national digital health system at extraordinary scale. Health accounts number in the high hundreds of millions, and record-linkage counts are of the same order. On any measure of identity infrastructure, this is among the most successful public digital projects anywhere.
The number that is not reported alongside it is how much clinical substance sits behind those identities. For most people, particularly outside institutional care, the answer is very little. An identity with nothing attached to it is an empty file.
Why the gap exists
Most outpatient care in India happens in small private clinics, and the software available to those clinics either handles billing with a clinical afterthought or assumes a hospital's staffing. Neither produces a coded record. So the identity exists, the consultation happens, and nothing durable is created.
What closes it
Two things, neither of them glamorous. Capture that produces coded data as a by-product of a clinician's ordinary typing, so that structure costs no extra time. And programmes that attach real clinical content — screening, laboratory results, consultation — to identities at population scale, which is what a school health programme is when it is done properly.
The identity layer was the hard part and it is largely done. The unglamorous part is what remains.
