Choosing the system where the medical records of thousands of employees will live isn't a software decision. It's a compliance decision with legal consequences, and it's worth making with a list of verifiable criteria instead of with a sales demo.
This guide brings together the criteria you actually can confirm before signing, ranked by how much trouble they can cause if they aren't met.
Criteria you can verify before you buy
The key word is verify. Many of the claims you hear during a sales process can't be confirmed until the system is already running — and by then, switching gets expensive. These five can be reviewed ahead of time.
1. Active certification under NOM-024
It's the only criterion with a binary, public answer. Mexico's Ministry of Health publishes the list of certified systems, and it shows the titleholder's legal name, the system's name and version, the certificate's scope, and its validity dates. If the system you're evaluating doesn't appear there, it isn't certified.
When you check it, confirm three things, not just the first one: that the certified version is the one that will actually be implemented, that the scope covers the type of service your company runs, and that the validity is still active.
2. Role-based access separation
The system needs to distinguish, by design and not through manual configuration, between who sees clinical detail and who sees administrative status. Medical staff need the full record of their patients; HR needs to know whether an exam was performed, the fitness result, and absences — without seeing diagnoses.
This is the feature that legally protects the company. Without it, any labor decision about an employee whose record was visible to the department that made the decision is exposed to being challenged.
3. Access traceability
Restricting access isn't enough if you can't prove it. The system needs to log who consulted which record and when, and that log needs to be exportable. In a review, that log is the difference between claiming a control exists and proving it.
4. Clinical standardization
Clinical information needs to be captured using standardized catalogs and classifications, not free-text fields. The difference shows up when you want to analyze your population: with catalogs, you can measure how many cases of a given condition exist at a plant; with free text, you get thousands of different ways of writing the same thing and no usable data.
5. Population analytics without exposing individuals
Leadership needs to understand the health of the population to make decisions — without accessing identifiable individuals. A system built for a company delivers that aggregated layer natively; one built for a private practice doesn't.
Note: always ask to see the certification live on the Ministry of Health's portal, not as a PDF emailed to you. It's the same information, and it takes thirty seconds.
Questions to ask any vendor
These five questions organize a sales conversation in a few minutes, because every one of them has a checkable answer:
- Under what legal name do you appear on the Ministry of Health's list of certified systems, and which version does the certificate cover?
- What are that certificate's validity dates?
- What exactly does an HR user see when they open an employee's profile? Show me on screen.
- Can I export the access log for the past twelve months?
- Does clinical capture use standardized catalogs or free-text fields?
Table 1
Three purchase criteria and how to confirm them before signing
| Criterion | How to verify it | Risk if missing |
|---|---|---|
| Active NOM-024 certification | Ministry of Health's public registry | Running an uncertified system for clinical records |
| Role-based access separation | Live demo with an HR user account | Labor decisions exposed to challenge due to access to medical information |
| Exportable access log | Request a sample export | Not being able to prove the control exists in a review |
Any criterion you can't verify before signing becomes an assumption. And assumptions get billed when an inspection arrives.
What to evaluate beyond the system itself
The software is only part of it. In a large operation, these three points determine whether the implementation actually works or stalls halfway.
Watch out: ask from the start how your existing records get migrated. An excellent system with three years of clinical history trapped in spreadsheets only solves half the problem.
Points that tend to get overlooked
- Multi-site operation. If you have several sites, each with its own medical service, the system needs to handle that structure without duplicating the same person's record.
- Record continuity. When an employee changes site or role, their clinical history needs to follow them.
- Vendor exit. Ask what format they'll hand over your information in if you ever decide to switch systems. The answer tells you a lot.
With these criteria, the evaluation stops depending on which demo was most convincing and starts resting on data anyone on your team can check.
