Radical interoperability has the power to truly change health care, but achieving it is no small task for any country. Singapore and Vietnam are relatively new to the game and don’t have the decades of legacy baggage that can make change difficult in the US and other countries. In some respects, this puts Singapore and Vietnam ahead of the pack in their ability to adopt a fully digital model. These countries can start with digital rather than having to digitize paper and outdated processes, which could make it possible to leapfrog ahead of other health systems. Consider this: Singapore’s Ministry of Health launched the country’s national Electronic Health Record in 2011 and is preparing to launch a next-generation EHR by next year. Low participation in earlier versions prompted the Ministry of Health to make it compulsory for providers to participate and share their data.2 In Vietnam, several hospitals are piloting EHRs, and the country expects to expand it nationally by 2020. Each citizen will have his or her own EHR, which will be monitored and stored for a lifetime.3 These represent interesting leading developments in the creation of a consolidated digital health record model, but it is still early in its evolution.
Other countries aren’t as far ahead when it comes to moving to a digital model. In Japan, for example, EHRs are still experimental, and interoperability between providers remains a challenge. Experiments are under way to make personal health information available to patients and providers via cloud computing, but it yet remains an experiment.4
In the Netherlands, most clinicians and all hospitals have an EHR, but there are no national standards, and interoperability between systems can be a challenge. In 2011, hospitals, pharmacies, and other provider groups established the Union of Providers for Health Care Communication, which is responsible for the exchange of data via an IT infrastructure, but patients must approve their participation and can drop out if they want.5
Australia is also making the move to digital. It has been about three years since the government launched the Australian Digital Health Agency to create a national digital health strategy. About 4 million patients—along with many of the country’s primary care providers—are now registered in an interoperable national e-health program. The record supports prescription information, medical notes, referrals, and diagnostic imaging reports. Patients are also able to add their own health information about allergies and adverse reactions, but some percentage of patients and practitioners have opted out.6
All of these models demonstrate both the promise and challenge of moving toward radical interoperability and consumer ownership of health data but in slightly different ways and with slightly different measures of success.
