History of Nursing Diagnosis

In nursing assessment, information is gathered from various sources to recognize cues and patterns that reflect a patient’s wellness level or existing health problems. Accurate identification of these patterns helps form diagnostic conclusions, which can be classified as:

Nursing Diagnoses: Clinical judgments primarily managed by nurses.

Collaborative Problems: Issues requiring interdisciplinary management.

Medical Diagnosis vs. Nursing Diagnosis

Medical Diagnosis: Identifies diseases, remains constant, and is treated by physicians and advanced practice nurses.

Nursing Diagnosis: Focuses on responses to health conditions, is flexible, and evolves with patient needs.

Collaborative Problems

Collaborative problems involve physiological complications that nurses monitor, often requiring joint intervention from other health professionals. For instance, in managing a surgical wound infection, roles include: Physician/Nurse: Prescribes antibiotics. Nurse: Monitors signs of infection, performs wound care. Dietitian: Recommends a protein-rich diet to aid healing.

Diagnostic Expertise and Clinical Decision-Making

Selecting appropriate nursing diagnosis involves diagnostic expertise, crucial for effective intervention planning. Clinical experience enhances this skill, enabling nurses to recognize specific diagnostic patterns quickly.

History of Nursing Diagnosis

The concept of nursing diagnosis began in the 1950s, with milestones including; 1953: Fry proposes nursing diagnoses. 1967: Yura and Walsh include analysis in the nursing process, transforming it into a five-step model. 1973: The first national conference on nursing diagnosis defines 80 diagnoses. 1980s and 1995: The American Nurses Association (ANA) includes diagnosis in nursing practice standards.

Purpose and Benefits of Nursing Diagnosis

Standardized nursing diagnostic statements: Provide precise definitions of patient health responses, facilitate communication among nurses and other health professionals and differentiate nursing roles and contribute to nursing knowledge development.

Evidence-Based Practice in Nursing Diagnosis

Research continues to validate and improve nursing diagnoses. Studies support nursing diagnoses’ relevance to diverse patient groups, enhancing intervention selection.

Nursing Diagnosis: A nursing diagnosis is a clinical judgment about a patient’s health status or response to a health condition that a nurse can address through specific nursing interventions. It goes beyond medical diagnosis to encompass physiological, psychological, and social factors. For instance, “Anxiety related to job security concerns” is a nursing diagnosis that guides interventions like patient education and support.

Collaborative Problem: A collaborative problem is a physiological complication that nurses monitor to detect changes in a patient’s status. Unlike independent nursing diagnoses, collaborative problems are conditions managed in partnership with other healthcare professionals (e.g., doctors, physical therapists) because they involve both nursing interventions and medical treatments. An example might be preventing infection in a postoperative patient by collaborating on wound care.

Medical Diagnosis: A medical diagnosis is a formal diagnosis given by a healthcare provider that identifies a specific disease or medical condition, like diabetes or pneumonia. Medical diagnoses address pathophysiological issues and are treated primarily with medical interventions. For example, “appendicitis” would be a medical diagnosis rather than a nursing diagnosis.

Types of Nursing Diagnoses (NANDA-I)

NANDA International recognizes three main types of nursing diagnoses:

Problem-Focused Nursing Diagnosis

It is a clinical judgment about an undesirable response to a health condition. The Characteristics are observable cues like behaviors or signs. For example: Acute Pain due to a surgical incision, addressed by focusing on pain relief interventions.

Risk Nursing Diagnosis

It is a judgment concerning the potential for an undesirable health response. The key elements are risk factors rather than defining characteristics. For example: risk for infection in a patient with an incision, guiding preventive care.

Health Promotion Nursing Diagnosis

It is a judgment concerning motivation and readiness to enhance health behaviors. The Characteristics are indications of the desire for health improvement. For example: Readiness for Enhanced Knowledge in a patient actively seeking information on wound care.

Common Nursing Diagnoses (Sample from NANDA-I List) 


Activity Intolerance, Anxiety, Risk for Infection, Acute Pain. Impaired Skin Integrity, Constipation, Nausea and Chronic Confusion, Ineffective Breathing Pattern

For effective application:

Problem-Focused Diagnoses: Tailor interventions based on specific related factors.

Risk Diagnoses: Identify risk factors and design preventive measures.

Health Promotion Diagnosis: Recognize patient motivation and support behavior changes.

Related Factor: A related factor is the underlying cause or contributor to the nursing diagnosis that the nurse can address through care. It gives context to the nursing diagnosis and indicates why the patient has the problem. In Mr. Lawson’s case, the related factor for his anxiety is his concern about returning to work and potential job loss.

North American Nursing Diagnosis Association International (NANDA-I): an organization that develops, maintains, and updates a standardized language for nursing diagnoses. NANDA-I’s classification system is widely used to ensure consistent nursing language across healthcare settings and to facilitate effective communication of patient care needs.

Problem-Focused Nursing Diagnosis: A problem-focused nursing diagnosis identifies a current health issue that a patient is experiencing. It is based on a set of defining characteristics and related factors. An example is “Acute Pain related to surgical incision,” which would require immediate intervention to manage the pain.

Critical Thinking and the Nursing Diagnostic Process

The nursing diagnostic process is fundamentally enhanced by critical thinking, allowing nurses to effectively assess and analyze patient data, ultimately forming accurate nursing diagnoses that guide patient-centered care. There are many elements:

Understanding Nursing Diagnoses and Their Components

NANDA-I Classification: Nurses rely on the NANDA International (NANDA-I) classification for standardized diagnoses, which provides diagnostic labels, definitions, defining characteristics, and related factors. This framework ensures that nurses can accurately identify and respond to patients’ health needs based on observable cues and consistent standards. Diagnostic Label: This is the official NANDA-I term describing the patient’s response to health conditions, such as “Deficient Knowledge” or “Readiness for Enhanced Knowledge.” Defining Characteristics: Observable cues that cluster together, supporting a specific diagnosis. These cues can include behaviors, symptoms, or patient statements. Related Factors: Elements associated with a patient’s condition, categorized as pathophysiological, treatment-related, situational, or maturational. Identifying these factors helps nurses to choose interventions that address specific needs.

Data Collection and Clustering

Data Clustering: Nurses collect both intentional (through physical exams or interviews) and unintentional cues (like observing a patient’s grimace during movement). These cues are then clustered to reveal patterns, leading to a logical understanding of the patient’s response to a condition. Example: Tonya, a nurse caring for Mr. Lawson, observes his lack of knowledge about post-surgical care. She clusters his questions and uncertainties, recognizing a pattern indicative of “Deficient Knowledge” but also sees potential for “Readiness for Enhanced Knowledge” as he expresses a desire to learn.

Data Interpretation

Analyzing Clusters: By comparing patterns within the data against NANDA-I standards, nurses can recognize relevant diagnoses and eliminate those that don’t align with observed cues. Example: When Mr. Lawson’s interest in understanding post-surgery care aligns with the NANDA-I criteria for “Readiness for Enhanced Knowledge,” this diagnosis becomes appropriate, as he lacks inappropriate or exaggerated behaviors that might indicate “Deficient Knowledge.”

Formulating Nursing Diagnoses

Accurate Diagnostic Statements: A precise nursing diagnosis includes a diagnostic label, defining characteristics, and a related factor (when applicable), avoiding generalized care. For instance, “Acute Pain related to surgical incision” specifically addresses the patient’s condition, guiding appropriate interventions. Tailored Care Planning: Diagnoses are contextualized within each patient’s unique situation, as in Mr. Lawson’s case, where his diagnosis of “Readiness for Enhanced Knowledge related to impending discharge with self-care needs” directs Tonya’s planning of educational interventions for his home care.

Application of Critical Thinking

Reflective Practice: Critical thinking is vital throughout the diagnostic process, requiring nurses to apply intellectual standards to analyze and interpret assessment data carefully. Repeated exposure to similar patient conditions enhances this skill, allowing nurses to recognize patterns and make more informed diagnoses. Collaborative Problem-Solving: By assessing potential risks and recognizing collaborative problems (like infection risk in postoperative patients), nurses work proactively with patients and other healthcare providers, developing preventive care strategies.

Example of Tailored Interventions Based on Diagnosis

Patient with Anxiety Related to Surgery: The nurse might address “Anxiety related to uncertainty over surgery” by offering detailed instructions and a dedicated time for questions, which helps the patient prepare emotionally and cognitively. Different Situational Anxiety: For a patient facing anxiety due to job loss, the nurse might engage a social worker and encourage health-promoting activities.

When forming and communicating nursing diagnoses, it’s essential to follow structured formats that allow for clear, standardized documentation. This ensures that other health care professionals understand the diagnosis and can provide coordinated care.

Two-Part Nursing Diagnosis Format

In many health care settings, a two-part nursing diagnosis is standard. This format includes: NANDA-I Diagnostic Label: The problem-focused diagnosis from the NANDA-I taxonomy. Related Factor: The contributing factor or etiology related to the diagnosis. Example: Acute Pain related to trauma of surgical incision. Impaired Physical Mobility related to incisional pain

The two-part format links the problem and its cause, allowing nurses to tailor interventions accordingly.

Three-Part Nursing Diagnosis (PES) Format

Some agencies may require a three-part format for more detail and clarity. This includes:

  • P (Problem): The NANDA-I label.
  • E (Etiology or Related Factor): The cause or contributing factor.
  • S (Symptoms or Defining Characteristics): Observable evidence or patient-reported symptoms showing the issue.

This format is often referred to by the acronym PES: Example: Impaired Physical Mobility related to incisional pain as evidenced by restricted turning and positioning.

By including symptoms, the PES format adds specificity, which can help in creating more targeted care plans.

Cultural Relevance in Nursing Diagnoses

Cultural awareness is vital in accurately assessing and diagnosing patients. Understanding patients’ beliefs, practices, and definitions of health can avoid misdiagnoses based on cultural bias. Example: The diagnosis “Sedentary Lifestyle” relies on the patient’s self-report of low physical activity. A nurse’s personal values around exercise should not influence this diagnosis, as cultural norms around physical activity vary. Questions that support culturally competent care might include:

“How does the patient define health and wellness?”

“What cultural practices or beliefs might impact their health behaviors?”

Data Cluster: A data cluster is a group of signs, symptoms, or patient data gathered during assessment that are related to each other. By clustering this data, nurses can identify patterns that help them make accurate nursing diagnoses. For example, in Mr. Lawson’s case, his concern about work, difficulty concentrating, and focus on incision pain form a data cluster that suggests anxiety.

Defining characteristics: are the signs and symptoms (observable and reportable cues) that point to a specific nursing diagnosis. These characteristics help validate and confirm the chosen diagnosis. In Mr. Lawson’s case, his statements about returning to work, difficulty concentrating, and physical discomfort are defining characteristics of potential anxiety.

Diagnostic label: is the standardized NANDA-I term that identifies a patient’s health problem based on assessment data. It provides a concise name for a patient’s condition, such as “Anxiety” or “Impaired Physical Mobility,” which directs the plan of care.

Health Promotion Nursing Diagnosis: A health promotion nursing diagnosis is a type of diagnosis that focuses on a patient’s motivation and readiness to increase well-being and achieve potential. This diagnosis indicates that the patient is showing signs of wanting to improve their health, such as “Readiness for Enhanced Knowledge” when a patient is eager to learn about postoperative care.

Risk Nursing Diagnosis: A risk nursing diagnosis identifies potential health problems that a patient may develop if preventative measures are not taken. It does not include defining characteristics, as the condition has not occurred yet but is a risk based on the patient’s situation. For example, a patient with a surgical incision may have the risk nursing diagnosis “Risk for Infection related to impaired skin integrity.”

Concept Mapping Nursing Diagnoses

Concept mapping in nursing is a visual tool that organizes and illustrates the connections between a patient’s multiple nursing diagnoses and health issues, facilitating critical thinking and comprehensive care planning. For nurses managing multiple diagnoses for each patient, concept mapping helps prioritize and clarify how each issue interrelates, enabling better-focused interventions and improved patient outcomes.

Key Steps in Concept Mapping Nursing Diagnoses:

Central Focus on the Patient: The concept map centers on the patient, not on a specific disease or condition. This patient-centered approach encourages nurses to focus on the individual’s unique health needs and goals, rather than viewing them only through the lens of their diagnoses.

Identify and Organize Diagnoses: Nurses start by gathering assessment data, including subjective information (like the patient’s own concerns) and objective data (such as lab results or physical observations). Patterns in the data help identify relevant nursing diagnoses, which are then labeled on the concept map. 

Link Diagnoses and Show Relationships: Concept maps show how diagnoses are interrelated. For instance, in Mr. Lawson’s case, Acute Pain is linked to his ability to engage in learning (Readiness for Enhanced Knowledge), as unmanaged pain may affect his attention and receptiveness. Related diagnoses can influence one another, allowing nurses to visualize cascading effects. For instance, Risk for Infection ties into post-operative pain and wound care, linking to how the nurse will instruct the patient on infection prevention and recovery.

Plan and Prioritize Interventions: By seeing how issues are interconnected, nurses can prioritize interventions based on which diagnoses have the most immediate impact. For Mr. Lawson, addressing his Acute Pain would take precedence to ensure he can participate in learning activities about Readiness for Enhanced Knowledge and adhere to infection prevention measures.

Dynamic and Holistic Approach: Concept maps facilitate a holistic approach by showing the complex relationships in care, helping the nurse visualize and anticipate how each intervention might influence other aspects of the patient’s health. This visualization aids in adjusting the care plan as new information emerges or as the patient’s condition evolves.

Advantages of Concept Mapping:

Enhanced Critical Thinking: Nurses learn to think through the connections between different health issues, ensuring that interventions are well-coordinated and patient-centered. Individualized Care Planning: By focusing on the patient’s unique needs, concept maps encourage personalized care. Patient Involvement: Concept mapping can also promote patient participation, as the map can illustrate the importance of each intervention in their care plan.

Sources of Diagnostic Errors

Diagnostic errors in nursing can arise at several points in the diagnostic process, including data collection, clustering, interpretation, and formulation of diagnostic statements. Recognizing the types and sources of these errors is essential to ensure accurate and effective patient care. There are many common sources of errors and strategies for minimizing them:

Errors in Data Collection: Sources of Error: Lack of knowledge or skill, inaccurate or missing data, and disorganization can lead to incomplete or faulty assessments. Prevention: Collect data systematically and comprehensively. For example, if a patient reports difficulty swallowing, gather detailed data on food types, pain description, and any alleviating factors. Use intellectual standards for thorough data collection.

Errors in Interpretation and Analysis: Sources of Error: Misinterpretation of cues, overlooking conflicting or insufficient cues, or failing to consider cultural or developmental factors can lead to diagnostic inaccuracies. Prevention: Confirm that subjective data (patient reports) aligns with objective findings (e.g., respiratory rate or lung sounds for “difficulty breathing”). Take cultural expressions into account, like understanding different expressions of pain.

 Errors in Data Clustering: Sources of Error: Premature clustering (diagnosing too soon), incorrect clustering, or failure to cluster data can result in misdiagnosis. Prevention: Group cues systematically and ensure all data is considered. For example, cluster urinary symptoms and assess comprehensively before diagnosing impaired elimination.

More on Sources of Diagnostic Errors

Errors in Diagnostic Statements: Sources of Error: Incorrect diagnostic labels, irrelevant etiologies, and including symptoms or goals within the diagnosis rather than the underlying issues. Prevention: Use NANDA-I terminology and ensure the problem identified is within the nursing scope to treat. Some key guidelines include:

Avoid Including Medical Diagnoses: Focus on the patient’s response rather than the medical diagnosis itself. For instance, use “Acute Pain related to trauma from surgery” instead of “Acute Pain related to colectomy.”

Use Appropriate Etiologies: The related factor should be treatable through nursing interventions. For example, use “Risk for Infection related to compromised skin integrity” rather than a diagnostic procedure as the cause.

Avoid Equipment-Focused Diagnoses: Base the diagnosis on patient responses to equipment rather than the equipment itself. “Deficient Knowledge regarding cardiac monitoring” is preferable to a vague statement like “Anxiety related to cardiac monitor.”

Patient-Centered Language: Ensure the diagnosis reflects the patient’s problems, not those of the nurse or healthcare team. Center the statement on patient-specific issues like “Risk for Infection” rather than problems related to nursing tasks.

Documentation and Informatics

In today’s healthcare environments, documentation of nursing assessments and associated care plans in electronic health record (EHR) systems is essential to maintain consistent and clear communication among healthcare providers. They are compatible. These systems also help nurses group information, facilitating accurate diagnostic selection and simplifying care planning.

The use of NAND-I terminology provides an evidence-based basis for nurse assessment, ensures patient safety and promotes effective communication within the healthcare team. These terms are constantly updated by professionals, making them a reliable and universally accepted standard. In EHR systems, nurses’ illnesses are often listed in chronological order, but the hierarchy that is useful in the care process is determined by priorities. Critical cases, such as acute pain, are dealt with immediately, while non-emergency illness is managed when time permits. Regular and updated nursing diagnoses ensure they reflect the patient’s current condition and care needs.

Critical thinking is inevitable when using an EHR for nursing care. Nurses should adhere to the information suggested by the chart and ensure that the chosen diagnosis reflects the patient’s specific circumstances and needs. Personalized infection screening strategies require careful examination of patient readiness, barriers, and past experiences, even when policy recommendations are available This critical thinking ensures care policies are inclusive and appropriate.

Nurse assessment guides care planning by formulating specific interventions. For example, a study such as “Impaired Skin Integrity” suggests interventions such as implementing a special help page or establishing a change program. Accurate documentation in the EHR demonstrates nurse accountability and ensures that the care plan effectively communicates patient needs to the healthcare team. By incorporating NANDA-I terminology into nursing activity classifications (NICs) and nursing outcomes classifications (NOCs), nurses can develop standardized care plans that link the intervention to measurable outcomes, providing communication improve and support high quality, personalized care across interdisciplinary teams.
