5 Red Flags in Charting by Exception: When Silence in the Medical Record Raises Questions

The 5 Red Flags Series | Rhonda Winter Consulting | Legal Nurse Consultant

When Less Documentation Doesn't Necessarily Mean Less Care

Charting by exception (CBE) was developed to make nursing documentation more efficient by allowing nurses to record findings that deviate from established norms, rather than repeatedly documenting expected findings.

As described in Methods of Documentation, published by Toronto Metropolitan University, charting by exception relies on established normal findings or expected activities, with documentation focused on deviations from those norms.

When properly implemented, it can be an effective documentation method. However, it relies on clearly defined standards, consistent assessments, and appropriate documentation of deviations from the expected clinical course.

The challenge arises when a medical record is reviewed months or years after an adverse event.

What does the absence of a nursing note actually tell us?

Does it indicate that the patient's condition remained within expected parameters? That an assessment was completed with no abnormal findings? Or that something clinically significant was not documented?

As a nurse manager and Legal Nurse Consultant, I recognize the importance of balancing efficient documentation practices with the need for a clear, accurate, and clinically meaningful record of patient care. Charting by exception can support efficiency, but it also requires careful consideration of what is documented, what is assumed, and what may be missing.

1. No Clearly Established Baseline Assessment

Charting by exception depends on knowing what constitutes a normal or expected finding for the individual patient.

A generic statement such as "within normal limits" may provide little insight into a patient's actual condition, particularly when the patient has significant comorbidities or an elevated risk of deterioration.

Consider a postoperative patient with pre-existing respiratory disease. What may be an acceptable oxygen saturation for that individual could differ from the standard reference range.

The Red Flag: The record relies on charting by exception without an identifiable patient-specific baseline or clear reference to the documentation standards being used.

What I Look For: Admission assessments, baseline observations, individualized care plans, facility documentation policies, and evidence that expected findings were appropriately established.

2. Changes in Patient Condition Without Corresponding Nursing Documentation

One of the greatest concerns with charting by exception occurs when objective clinical information suggests a change in condition, but the nursing notes remain silent.

For example, a postoperative patient develops increasing tachycardia, declining blood pressure, or escalating oxygen requirements.

The vital sign flowsheet may demonstrate these changes, yet the nursing documentation contains no corresponding assessment, intervention, or escalation.

The Red Flag: A change in clinical status is evident elsewhere in the record, but the related nursing assessment and response cannot be identified.

What I Look For: Trends in vital signs, medication administration records, physician orders, laboratory results, communication records, and documented responses to deterioration.

The important question is not simply whether a narrative note exists, but whether the complete record demonstrates appropriate recognition and management of the change.

3. Missing Documentation of Clinical Judgment and Decision-Making

Charting by exception can document findings efficiently, but it should not obscure important nursing decisions.

Consider a patient reporting increasing postoperative pain despite analgesic administration.

The medication administration record confirms additional analgesia, but no reassessment or clinical rationale is documented.

Was the pain reassessed? Were other potential causes considered? Was the surgeon or anesthesiologist notified when indicated?

The Red Flag: Interventions are documented, but the assessment, clinical reasoning, or evaluation supporting those interventions is unclear or missing.

What I Look For: Evidence of the nursing process, including assessment, planning, implementation, and evaluation.

Documentation should allow another healthcare professional to understand what occurred and how the patient responded.

4. Documentation Gaps During Critical Transitions of Care

Transitions between clinical areas are particularly important when reviewing perioperative records.

Consider the transfer of a patient from the operating room to the Post-Anesthesia Care Unit (PACU), or from PACU to an inpatient unit.

Charting by exception may be used in one department while another relies on narrative notes, structured assessments, or electronic flowsheets.

The resulting documentation can appear fragmented.

The Red Flag: Important information regarding patient status, outstanding concerns, interventions, or transfer readiness is difficult to follow across the transition.

What I Look For: Transfer assessments, handoff documentation, relevant clinical trends, outstanding orders, receiving nurse assessments, and continuity of the care plan.

The absence of a narrative note does not establish that communication failed. However, it may make it more difficult to determine precisely what information was communicated.

5. Reliance on Checkboxes or Default Electronic Documentation Without Supporting Clinical Detail

Electronic health records have made structured documentation increasingly common.

Checkboxes, predetermined normal findings, and templated assessments can improve consistency and efficiency.

However, concerns arise when structured entries appear inconsistent with other clinical information.

For example, an electronic assessment indicates that respiratory status is normal, while another section of the record shows increasing oxygen requirements and respiratory distress.

These differences require closer investigation.

The Red Flag: Structured or templated documentation appears inconsistent with the patient's clinical condition or other contemporaneous records.

What I Look For: Contradictory findings, documentation timestamps, assessment frequency, relevant electronic record functionality, and whether significant findings were captured elsewhere.

A checked box does not necessarily tell the full clinical story.

A Composite Clinical Scenario

Consider a patient recovering from abdominal surgery.

The nursing documentation uses charting by exception. During the postoperative period, the vital sign record demonstrates a progressively increasing heart rate and declining blood pressure.

Additional intravenous fluids are administered, and laboratory investigations are ordered.

However, the nursing notes provide limited information regarding assessment findings, clinical concerns, communication with the treating team, or response to interventions.

The absence of detailed narrative documentation raises questions, but does not establish that nursing care was inappropriate.

A thorough review would consider the entire medical record, applicable policies, clinical expectations, and whether other entries explain the assessments and decisions made.

This scenario is fictional and provided for educational purposes. It is not based on an identifiable patient or legal case.

Why Charting by Exception Matters in Medical-Legal Review

Charting by exception should not automatically be interpreted as inadequate documentation.

The critical question is whether the method, as used in the particular clinical setting, provides a reliable and sufficiently complete account of the patient's care.

A Broader Canadian Perspective

Across Canada, provincial nursing regulators establish professional expectations for documentation, regardless of whether an organization uses narrative charting, electronic flowsheets, or charting by exception.

The British Columbia College of Nurses and Midwives (BCCNM) Documentation Practice Standard establishes expectations for documenting nursing assessments, care planning, interventions, communication, and outcomes.

The standard recognizes documentation as an important record of nursing knowledge, skills, and clinical judgment, including its potential use as evidence in legal proceedings.

Similarly, the College of Nurses of Ontario (CNO) Documentation Practice Standard, effective February 1, 2026, establishes professional expectations for accurate, complete, and timely nursing documentation.

Of particular relevance, the CNO specifically addresses charting by exception in its practice support guidance. The CNO explains that charting by exception is an employer-driven documentation approach and emphasizes that organizations should have clear policies defining expected normal findings and when exceptions must be documented.

This distinction is particularly important in medical-legal record review. Evaluating charting by exception requires consideration of not only regulatory documentation expectations, but also the facility's policies, established documentation practices, and the patient's clinical circumstances.

The College of Registered Nurses of Alberta (CRNA) and the College of Registered Nurses of Saskatchewan (CRNS) emphasize clear, accurate, timely, and clinically meaningful documentation that reflects nursing assessments, interventions, clinical reasoning, and patient responses.

Of particular relevance, the College of Registered Nurses of Manitoba (CRNM) specifically addresses charting by exception. Its guidance explains that effective charting by exception depends on current patient assessments, evidence-informed clinical protocols, and clearly established criteria for assessments and interventions.

Similarly, Quebec's Ordre des infirmières et infirmiers du Québec (OIIQ) requires nursing documentation to reflect clinical assessments, decision-making, interventions, and continuity of care.

From both a nursing management and Legal Nurse Consultant perspective, these expectations reinforce an important principle: documentation efficiency must never compromise the ability to understand the patient's clinical course and the nursing care provided.

In medical-legal review, the applicable provincial regulatory expectations, employer policies, documentation methods, and standards in effect at the time of care must all be considered.

The Canadian Nurses Protective Society (CNPS), in Quality Documentation: Your Best Defence, also emphasizes that documentation serves as a record of patient care, supports communication and continuity, and can become important evidence in professional complaints or legal proceedings.

For plaintiff counsel, documentation gaps may identify areas requiring further investigation.

For defence counsel, understanding the facility's charting-by-exception framework may help explain why a traditional narrative entry does not appear and where supporting evidence may be found.

The absence of a narrative note is not necessarily the absence of assessment, intervention, or care. Equally, charting by exception should not be used to assume that appropriate care occurred without examining the supporting record.

Final Thoughts

Effective documentation is not measured by the number of words entered into the medical record.

It is measured by whether the documentation communicates a clear, accurate, and clinically meaningful account of the patient's care.

For a Legal Nurse Consultant, reviewing charting by exception requires looking beyond the absence of narrative notes to understand what was expected, what was documented, and what the complete medical record reveals.

Sometimes the most important question is not what was charted, but what the documentation allows us to reasonably conclude.

A red flag is not proof of negligence. It is a reason to look deeper.
