The Anatomy of a Chart How to read and interpret an EHR

When you’re new to nursing, there are so many important details to keep track of, including patient charts, also known as electronic health records (EHRs). Get some advice on what information is vital to maintaining accurate and up-to-date patient records while on the job.

Navigating the electronic health record (EHR), commonly known as the “chart,” can be challenging as you begin your nursing school and clinical journey. Once you log in, you may feel overwhelmed by the endless amount of information and tabs to access. You might find yourself asking, “Where do I even begin?” Don’t worry—this is normal and happens to everyone. So, let’s review six key sections of the EHR that you can start with when researching your client for clinical.

1. Client Demographics

Client demographic information is a simple place to begin your exploration of the EHR. This section typically includes the client’s name, date of birth, and may also contain important details such as isolation status, code status, admission date, and allergies. 

2. Admission Progress Note

After reviewing the client’s demographics, you should access the client’s admission note, which is usually written by a healthcare provider, such as a doctor or nurse practitioner. This progress note provides a detailed description of why the client came to the hospital and includes comprehensive data regarding their first physical assessment, past medical history, family history, and social history. Keep your eye on the prize—this note may answer the question of “what will get your patient discharged?” by outlining the provider’s plan for the rest of the hospital stay.

3. Test Result Impressions

Depending on the healthcare provider’s orders, clients often have blood (lab) work and diagnostic testing scheduled consistently throughout their hospital stay. Sometimes viewing these test results can be overwhelming and time-consuming; therefore, focus your investigation on the impression of these results. Usually, each test result contains a concise summary written by the clinician interpreting the findings, which can help you better understand your client’s condition.

Most charts also include tools to examine data trends over time—for example, you can check if a client’s Red Blood Cell (RBC) count is increasing or continuing to fall.

4. Medication Administration Record

The Medication Administration Record (MAR) is another vital part of the chart that provides information about the client’s past, current, and future medications. Although you might not be administering medications right away, the MAR can help you understand how medications impact your client’s assessment findings and vital signs. If you have any questions, call the pharmacy—a pharmacist can be your best resource for medication-related questions. 

5. Nursing Assessment Notes

Nurses typically write assessment notes on every client once per shift, which means your assigned client can have dozens of notes to review. To better understand your client’s condition, read the last few days or shifts’ worth of nursing notes to compare baseline assessments and vital sign data to your current findings. 

6. Health Care Maintenance (HCM)

While your patient is in the hospital, make sure their HCM is up-to-date. Often what they need is available while they are inpatient, such as vaccinations

Remember, everything you learn from a chart should be validated, often by the patient themselves, and it should guide you in providing the best possible care. Always make sure the provider’s goals align with the patient’s goals.
