Why India's Next Healthcare Leap Depends on Who Controls the Data

On September 17, the World Health Organization marks World Patient Safety Day 2026 under the theme "Safe care for non-communicable diseases" and the slogan "Safe care for life," a reminder that globally, one in ten patients is harmed during care, and roughly half of that harm is preventable. As patient-centric healthcare technology races ahead in India, that statistic frames an uncomfortable question.Is all this data, AI and connected infrastructure making patients safer, or simply making healthcare more digital?

According to Dr. Saibal Roy Chowdhury, Director - Medical Operations (East) and HOD Anaesthesiology (East) at Narayana Health, the shift the industry now needs is not more technology pointed at the patient, but technology controlled by the patient. India already has the scale to test this nationally: the Ayushman Bharat Digital Mission has issued more than 93.95 crore Ayushman Bharat Health Account IDs and linked over 105 crore digital health records across 5.33 lakh registered facilities, making it one of the largest digital health ecosystems in the world. The infrastructure exists. What remains unresolved is control.

From Patient-Centric to Patient-Controlled

The distinction matters more than it sounds. Healthcare has largely operated on default data access, where hospitals, insurers and labs hold and move information with only implicit patient consent. The next step, according to the expert response, is permission-based access: patients should have clear, user-friendly digital tools to decide exactly who can view their information, for what purpose, and for how long, with the ability to review access history and revoke permissions at any time.

"Patients should have clear, user-friendly digital tools to decide who can view their information, for what purpose and for how long. They should also be able to review access history and withdraw permissions, with every data interaction recorded transparently."

Interoperability Is a Trust Problem, Not a Plumbing Problem

Healthcare interoperability in India is often reduced to a technical milestone: getting systems to exchange data. But data reaching a clinician unfiltered, out of context, or without a traceable source isn't progress, it is a bigger version of the same problem. True interoperability standardises data, verifies its accuracy and currency, and presents it in a prioritised, usable format that supports a clinical decision rather than adding to an inbox of alerts.

That also means redesigning the unit interoperability is built around. Instead of hospitals, insurers, labs or platforms each optimising for their own workflows, the patient's entire journey, from prevention and diagnosis through treatment, discharge and home monitoring, should be the connective thread, with every stakeholder functioning as a linked point along it rather than a silo.

The biggest obstacle to that vision isn't technology. It is fragmented incentives and organisational culture: proprietary systems, inconsistent standards and commercial interests that discourage data-sharing. Overcoming that requires open standards, enforceable data-sharing rules, shared incentives and stronger governance, including a seat for patients in decisions about their own information.

Who's Accountable When AI Gets It Wrong?

As AI in clinical decision-making becomes more common, from diagnostic support to predictive alerts, the accountability question sharpens considerably. The clearest boundary drawn is this: AI can advise, but it cannot be held accountable.

"AI can advise, but it cannot be accountable. The clinician remains responsible for the final medical decision, while healthcare institutions must ensure safe deployment and technology providers must stand behind the system's testing, design and limitations." Dr. Saibal Roy Chowdhury, Director - Medical Operations (East) and HOD Anaesthesiology (East), Narayana Health

That framework distributes responsibility deliberately: clinicians own the final decision, institutions own safe deployment, and technology developers own the testing and limitations of what they build, with patient preferences and informed consent kept central throughout. Clear liability frameworks, not assumptions, are what make that distribution enforceable in practice.

Curating Data, Not Just Collecting It

Wearables, genomics and remote monitoring are generating patient data faster than most systems can meaningfully use it, risking real information overload for clinicians and patients alike. The fix isn't more dashboards; it is better curation, filtering out low-value information, surfacing meaningful trends, personalising alerts, and clearly identifying the next action for every data point. A reading that doesn't support a decision, help a patient understand their health, or trigger a response is not insight, it is noise.

The Real Test of Patient Centricity

For India's digital health ecosystem, matching WPSD 2026's call for safer, coordinated NCD care will depend less on how many devices, sensors or AI models get deployed, and far more on whether patients can trust, understand and actually control what happens to their data once collected. That, ultimately, is what turns patient-centric technology into genuinely patient-controlled healthcare.
