Electronic Medical Records (EMRs) have transformed health delivery, but the impact goes well beyond the hospital. They are changing public health policy by facilitating evidence-based choices, disease prevention and international health cooperation. Using the vast amounts of data held in EMR systems, policymakers can better identify public health issues and devise interventions to improve population health.
Empowering Data-Driven Policies
EMRs are the treasure chest of anonymized health data, and policymakers can view trends in real time. By tracking trends in chronic conditions such as diabetes or cardiovascular disease, for instance, EMRs let officials design targeted preventative campaigns. Health information aggregated from EMRs has been used to allocate funding, for example, boosting funding in areas with high levels of preventable diseases.
EMRs in rural or marginalized areas enable policymakers to identify care inaccessible. If you know where there is low vaccination coverage or health systems, then it is time to act against inequality. This data-based strategy has been instrumental in initiatives such as the National Immunization Program, which uses EMR data to slash vaccine waste.
Revolutionizing Disease Surveillance
EMR systems are the operative means to monitor and intervene when public health problems arise. EMRs provided contact tracing, outcome tracking and vaccine tracking during the COVID-19 pandemic, for instance. These capacities allowed public health departments to respond better to the rapid flux.
Other than pandemics, EMRs help in the detection of endemic diseases such as tuberculosis or malaria. For those countries with populated EMR networks, authorities in health services are able to pinpoint spikes in cases, dispatch medics, and stop outbreaks. The control program for tuberculosis in India, for example, relies on electronic health records to monitor and administer medication to patients, minimizing drug resistance and maximizing cure.
Enhancing Preventive Healthcare
EMRs are also central to preventive care, predicting who is at risk for disease. Public health programs based on predictive analytics use EMR data to identify people who are at risk, for example because of obesity, smoking or genetic predispositions. EMR expansion also comes from wearable devices and mobile health apps. Fitness tracker data, for instance, can add value in population-level activity and health data, as opposed to standard EMR data. Policymakers can draw on this live data to construct more dynamic health policies and programs.
EMRs have also been applied to maternal and child health policies. With data from prenatal care, governments have been able to provide interventions to minimize complications during pregnancy and childbirth. Programs such as the ones in sub-Saharan Africa that track maternal health using electronic records have already cut maternal mortality.
Global Collaboration in Health Policy
The opportunity for EMRs to catalyze cross-border collaboration is enormous. Exchanged EMR and data standards make it possible to collaborate across borders on global health issues. In West Africa, for instance, during the Ebola pandemic, digital health records facilitated reporting by global health systems on patient outcomes and efficient use of resources.
The WHO is also attempting to standardize health information systems in all member states, so EMR data can be made available more easily and used. Such measures not only strengthen global pandemic response but also treat chronic conditions such as diabetes and hypertension through standardized care recommendations.
Bridging Healthcare Disparities
EMRs can also help narrow health disparities. They give data on treatment results across populations, which help policymakers design equitable health policies. In the United States, for example, the Office of Minority Health analyses EMR data to identify health inequalities among underserved groups and makes targeted interventions to improve access to care.
Community health programs in Canada also rely on EMR data to provide indigenous populations with culturally responsive and efficient healthcare services. These systems also track interventions’ success so that the funds get directed where they’re needed.
Integration and interoperability are where EMRs are headed in public health. New technologies such as blockchain and artificial intelligence are integrated into EMRs to support data protection and analytics. Blockchain can guarantee records that cannot be altered; AI can scale data to see where the public health needs of the future lie.
EMR systems grow as well with wearables and mobile health apps. For instance, fitness tracker data can be used to help understand trends in population activity and health, which are not always captured in EMRs. This real-time data can be applied to more interactive health policies and programs by policymakers.
