1. Begin with a common vision of “one patient, one record.”
Interoperability begins with alignment, not with software.
Different stakeholders like hospitals, insurers, public health departments, state schemes, and technology vendors have to agree on one single principle:
Every patient is entitled to a unified, longitudinal, lifetime health record, available securely whenever required.
Without this shared vision:
A patient should not carry duplicate files, repeat diagnostics, or explain their medical history again and again simply because systems cannot talk to each other.
2. Adopt standards, not custom formats: HL7 FHIR, SNOMED CT, ICD, LOINC, DICOM.
When everyone agrees on the same vocabulary and structure, interoperability then becomes possible.
This means:
Data flows naturally when everyone speaks the same language.
A blood test from a rural PHC should look identical – digitally – to one from a corporate hospital; only then can information from dashboards, analytics engines, and EHRs be combined without manual cleaning.
This reduces clinical errors, improves analytics quality, and lowers the burden on IT teams.
3. Build APIs-first systems, not locked databases.
Modern health systems need to be designed with APIs as the backbone, not after the fact.
APIs enable:
An APIs-first architecture converts a health system from a silo into an ecosystem.
But critically, these APIs must be:
Otherwise, interoperability becomes risky, instead of empowering.
4. Strengthen data governance, consent, and privacy frameworks.
Without trust, there is no interoperability.
And there will not be trust unless the patients and providers feel protected.
To this end:
If people feel that their data will be misused, they will resist digital health adoption.
What is needed is humanized policymaking: the patient must be treated with respect, not exposed.
5. Gradual, not forced migration of legacy systems.
Many public hospitals and programs still rely on legacy HMIS, paper-based processes, or outdated software.
Trying to forcibly fit old systems into modern frameworks overnight, interoperability fails.
A pragmatic, human-centered approach is:
Digital transformation only succeeds when clinicians and health workers feel supported and not overwhelmed.
6. Invest in change management and workforce capacity-building.
Health systems are, after all, run by people: doctors, nurses, health facility managers, data entry operators, and administrators.
Even the most advanced interoperability framework will fail if:
Interoperability becomes real when people understand why data needs to flow and how it improves care.
Humanized interventions:
The human factor is the hinge on which interoperability swings.
7. Establish health data platforms that are centralized, federated, or hybrid.
Countries and states must choose models that suit their scale and complexity:
Centralized model
All information is maintained within one large, single national or state-based database.
Federated model
Data remains with the data originators; only metadata or results are shared
Hybrid model (most common)
The key to long-term sustainability is choosing the right architecture.
8. Establish HIEs that organize the exchange of information.
HIEs are the “highways” for health data exchange.
They:
This avoids point-to-point integrations, which are expensive and fragile.
The India’s ABDM, UK’s NHS Spine, and US HIE work on this principle.
Humanized impact: clinicians can access what they need without navigating multiple systems.
9. Assure vendor neutrality and prevent monopolies.
When interoperability dies:
Procurement policies should clearly stipulate:
A balanced ecosystem enables innovation and discourages exploitation.
10. Use continuous monitoring, audit trails and data quality frameworks.
Interoperability is not a “set-and-forget” achievement.
Data should be:
Data quality translates directly to clinical quality.
Conclusion Interoperability is a human undertaking before it is a technical one.
In a nutshell
seamless data integration across health systems requires bringing together:
Continuous Monitoring In the end, interoperability succeeds when it enhances the human experience:
Interoperability is more than just a technology upgrade.
It is a foundational investment in safer, more equitable, and more efficient health systems.
