Implementing EHRs in nursing practice has multiple benefits that improve patient care and nursing outcomes. These are some of the key benefits:

Enhanced Data Access

EHRs provide healthcare teams with instant access to comprehensive patient information and can result in better-informed clinical decisions. 

Nurses can review a patient's medical history, allergies, medication lists, and diagnostic results. Improving the accessibility of patient information can promote patient safety while mitigating the risk of medical errors.


EHRs help facilitate effective communication and collaboration between healthcare providers. Nurses and other healthcare professionals can electronically share patient information, care plans, and clinical notes. 

EHRs can promote care coordination by enhancing communication while ensuring continuity across various healthcare settings and disciplines. 


EHRs help streamline the documentation process while saving time on manually writing patient information. 

Nurses can electronically document assessments, interventions, and outcomes—this can help ensure accuracy while removing any concerns about legibility. Because EHRs can help nurses save time on documentation, they can focus more on direct patient care.

2. Clinical Decision Support Systems (CDSS)

A clinical decision support system (CDSS) is another example of informatics in nursing that improves patient care. CDSSs are software tools providing healthcare workers with evidence-based information and patient-specific data to assist with clinical decision-making.

CDSS Applications in Nursing Informatics

A CDSS analyzes patient information and delivers alerts, reminders, guidelines, and recommendations to improve patient outcomes. 

CDSSs assess vital signs, laboratory results, and clinical observations to identify life-threatening risks and deliver real-time alerts to healthcare professionals.

CDSS Benefits 

Like other informatics tools, CDSSs offers multiple benefits that support nursing practice while improving patient care. Some key CDSS benefits are:

Evidence-Based Decision-Making

CDSSs supply healthcare professionals with easy access to evidence-based guidelines, protocols, and best practices. They help nurses make informed decisions by incorporating cutting-edge research and clinical knowledge into their practice, promoting high-quality care.

Medication Safety

CDSS technology can generate alerts and reminders for medication safety based on patient-specific data. These alerts include drug interactions, medication allergies and sensitivities, and dosage adjustments. With safeguards like this in place, CDSSs help minimize the risk of medication errors while promoting the safe administration of medicine.

Care Planning

CDSSs can support nurses in managing chronic conditions and creating individualized care plans. This software can guide disease-specific assessments while enhancing care coordination.

Clinical Guidelines

CDSSs can also help nurses to adhere to clinical guidelines and care pathways. This technology can provide prompts for screenings, preventative care, and patient follow-ups, offering comprehensive guidance and evidence-based care.

3. Telehealth and Telemedicine

Telehealth and telemedicine are nursing informatics examples that use various digital technologies to deliver healthcare services remotely.

Telehealth encompasses several services, including remote monitoring, patient education, and virtual consultations.
