different EMR systems were perfected ("interoperability"), it would facilitate the coordination of health care delivery in nonaffiliated health care facilities. In addition, data from an electronic system can be used anonymously for statistical reporting in matters such as quality improvement, resource management, and public health communicable disease surveillance. However, it is difficult to remove data from its context. Usefulness for patients Sharing their electronic health records with people who have type 2 diabetes helps them to reduce their blood sugar levels. It is a way of helping people understand their own health condition and involving them actively in its management. Usefulness for research Electronic medical records could also be studied to quantify disease burdens – such as the number of deaths from antimicrobial resistance – or help identify causes of, factors of, links between and contributors to diseases, especially when combined with genome-wide association studies. For such purposes, electronic medical records could potentially be made available in securely anonymized or pseudonymized forms to ensure patients' privacy is maintained. This may enable increased flexibility, improved disease surveillance, better public health monitoring, and novel life-saving treatments. Theoretically, free software such as GNU Health could be used or modified for various purposes that use electronic medical records i.a. via securely sharing anonymized patient treatments, medical history and individual outcomes (including by common primary care physicians). Electronic health records could also support clinical decision support systems. Moreover, they could be used among other biodata for digital twins (also called health avatars) for personalized medicine. Artificial intelligence systems could use this data among other integrated data to screen for potential diseases with multimodal learning. Such records could also be used for matching patients to clinical trials with software. Emergency medical services Ambulance services in Australia, the United States and the United Kingdom have introduced the use of EMR systems. EMS Encounters in the United States are recorded using various platforms and vendors in compliance with the NEMSIS (National EMS Information System) standard. The benefits of electronic records in ambulances include: patient data sharing, injury/illness prevention, better training for paramedics, review of clinical standards, better research options for pre-hospital care and design of future treatment options, data based outcome improvement, and clinical decision support.
