Functions of EHR

The EHR serves as an online tool that allows healthcare workers to review patient records at all levels of care, engage in communication and collaboration with the rest of the healthcare team, and focus on the patient (Ehrenstein et al., 2019). Health information systems are complex and comprehensive, requiring more focused planning and leadership when implemented, especially in projects with multiple stakeholders. Therefore, this paper will focus on the functions of electronic health records in the healthcare system.

The Functions of Electronic Health Record (EHR)

Since EHRs involve a computerized system for the input and storage of patient information, the face of the health sector has changed. These systems have become fundamental structures of the current healthcare delivery systems, thereby enhancing the quality, productivity, and effectiveness of patient treatment. EHRs have several functions and are used as patient records, management tools, and decision-support systems.

Comprehensive Patient Records

Another aspect of EHRs is that the system must be able to capture all records of the patient. While paper-based patient records have fragmented information, which can be hard to collate and share with other providers, if necessary, EHRs give a holistic view of the patient (Das, 2023). This makes it possible to get a patient summary, including diagnosis, treatment, medications, and allergies at the point of care. Such kind of access is particularly crucial in order not to have gaps in care, which patients with multiple chronic illnesses, acute, or multiple specialists may have. It also reduces incidences where the same service is delivered by different organizations, which can take a lot of time for the patient and the provider of care.

Improved Collaboration and Integration

EHRs also improve the working relations between the members of the multidisciplinary medical team in terms of collaboration and integration. The incorporation of the EHR into the care process also facilitates the enhancement of the flow of information within the care team members and access to the patient’s records (Das, 2023). This is especially the case where a lot of people with special skills and knowledge are involved in the process of addressing a given issue. For example, general practitioners, cardiologists, and dieticians can all be allowed to access one patient record and treat the patient holistically. Such an approach can help improve the performance of the health system delivery and patient care.

Decision-Support Systems

Another significant role of EHRs is that they can help with decision-making that takes place in clinical practice. Almost all EHR systems have a decision-support tool that gives alerts and reminders to the various caregivers involved (Tsai et al., 2020). These tools can notify the practitioners of any likely interactions between the administered drugs, suggest other forms of treatment depending on the patient's history, and inform the practitioners of any important preventive measures such as immunizations and screenings. These features are provided at the point of care so that decision-making becomes more rational and less prone to errors and unsafe practices. For example, if a doctor admitting a new patient prescribes a medication, the system will be able to look for compatibility with other drugs and inform the physician.

Administrative Efficiency
Next, besides the clinical benefits, EHRs offer a high and measurable organizational value for administrative activities (Tsai et al., 2020). They help reduce time spent on activities such as appointment setting, billing, and coding since they are automated. This not only takes some of the burden off healthcare staff for their work-related tasks but also helps eliminate errors associated with manual data entry. For example, when the patient is to be discharged from the hospital, the EHR can also search for the appropriate codes for billing and prepare the bill on behalf of the patient. This speeds up the billing process and also minimizes the chances of insurance companies missing some claims due to specific code issues.

Population Health Management

Another important use of EHR is in the field of population health. Since EHR systems process information from a large number of patients, these systems help in evaluating the general state of health and tendencies (Kruse et al. , 2018). The information is useful for a public health worker and the healthcare facilities to help in identifying an issue with the population. For example, data from EHRs can reveal how many patients have chronic diseases such as diabetes and hypertension, and what needs to be done to treat their conditions. All these interventions are effective at the population level and are used in the prevention of primary and secondary diseases.

Patient Engagement

Consequently, another domain that has benefited from the adoption of EHRs is that of patients’ engagement. Most EHR systems have a patient portal where patients can look at their information, communicate with the provider, ask for a prescription, or schedule another appointment. This is particularly pertinent given that patients are forced to believe that they are also capable of contributing to the decision-making process on how to handle their illnesses and consequently embrace the prescribed treatment regimens and other forms of therapy (Kruse et al. , 2018). For instance, the patient with diabetes can check on blood glucose levels, get reminders for when to take a certain medication, and report any side effects to the care team through the portal.

Advancement of Medical Research
In addition, EHRs are also useful in the development of medical knowledge (Kruse et al. , 2018). Since EHRs are currently implemented, it is apparent that there is a vast quantity of data available for clinical and medical purposes. Here, information about patients can be useful to healthcare providers to enhance their capacity to predict treatment outcomes and effectiveness, and to develop new cures. This capability is helpful in the advancement of discovery in the medical field and the enhancement of health quality in people. For instance, during the COVID-19 pandemic, EHR data have been used to define the specifics of the virus, identify potential factors associated with its dissemination, and even inform treatment approaches.

Challenges of EHR Integration
Nevertheless, EHR integration also has its drawbacks despite all the advantages associated with it. Among the issues to tackle is the security of patients’ information and their privacy rights (Menachemi & Collum, 2020). The recent rise in cyber-attacks and breaches also makes it compulsory for any healthcare organization to ensure adequate data security. Additionally, the conversion from paper records to EHRs requires significant funds for information technology and training. To do this, adequate time has to be provided for the training of the health care providers and ensure that the changes that the new system brings are reasonable and do not interfere with the working of the system.

Conclusion

EHRs are an important component of the healthcare system that includes multiple roles that are beneficial to patients, clinicians, and healthcare organizations. They improve communication between carers, foster consumers' participation in healthcare processes, and facilitate medical and public health progress. However, the benefits associated with EHRs can be said to outweigh the challenges, and they are useful tools in the endeavor to achieve better health. In the future, EHR systems are likely to be more developed to improve the provision of healthcare services to citizens of the world.
