The Foundational Five-Step Nursing Process (ADPIE)
Ida Jean Orlando first developed the nursing process in 1958, and it remains a cornerstone of nursing education and practice today. This systematic, five-step approach ensures that patient care is not only standardized but also responsive and adaptable to individual needs. The process is a cyclical framework that guides clinical decision-making, prioritizes patient safety, and promotes positive health outcomes.
Step 1: Assessment
The assessment phase is the critical first step where a nurse gathers and analyzes comprehensive data about a patient's health status. This collection involves both subjective and objective data. The nurse uses critical thinking skills throughout this process to identify potential health issues, risks, and the patient's overall condition.
Types of Data Collection
- Subjective Data: This is information reported directly by the patient or their caregivers, such as symptoms, feelings, or pain levels. It is the patient's personal, qualitative experience of their health.
- Objective Data: This includes measurable, tangible data that can be observed and verified. Examples include vital signs (temperature, pulse, respiration, blood pressure), height, weight, laboratory results, and physical examination findings.
- Data Sources: Information can be gathered from primary sources (the patient), secondary sources (family, caregivers), and tertiary sources (medical records, health literature).
Step 2: Diagnosis
After a thorough assessment, the nurse uses their clinical judgment to formulate a nursing diagnosis. This differs from a medical diagnosis; while a doctor diagnoses a disease, a nurse diagnoses a patient's response to that health condition or life process. This clinical judgment identifies the patient's actual or potential health problems and their underlying factors, which directly informs the rest of the care plan. The North American Nursing Diagnosis Association (NANDA) provides an updated list of standardized nursing diagnoses.
Step 3: Planning
During the planning phase, the nurse creates a customized care plan to address the identified nursing diagnoses. This step involves setting realistic, patient-specific goals and expected outcomes. Effective goals are often guided by the S.M.A.R.T. criteria:
- Specific: Clearly defined goals.
- Measurable: Outcomes that can be tracked and quantified.
- Achievable: Realistic goals that are attainable for the patient.
- Relevant: Goals that are pertinent to the patient's needs.
- Time-bound: Goals with a specific timeframe for achievement.
Nursing Interventions and Care Plans
The planning phase also outlines the specific nursing interventions—actions the nurse will take to help the patient achieve their goals. These interventions are documented in the nursing care plan, which provides a roadmap for the entire healthcare team.
Step 4: Implementation
Implementation is the action-oriented step where the nurse carries out the interventions outlined in the care plan. This phase is where direct patient care occurs and can include a wide range of activities.
Examples of Implementation Actions
- Administering Medications: Following a doctor's orders and treatment protocols.
- Performing Treatments: Such as wound care or applying medical devices.
- Providing Education: Teaching the patient or family about their condition and self-care.
- Offering Emotional Support: Helping the patient cope with their health challenges.
- Collaboration: Coordinating with other healthcare professionals, like physical therapists or dietitians.
Step 5: Evaluation
In the final step, the nurse evaluates the effectiveness of the interventions and determines whether the patient's desired outcomes were achieved. This requires continuous reassessment and comparison of the patient's current status with the goals set during the planning phase.
The Cyclical Nature of the Process
The nursing process is not linear but cyclical. If the evaluation shows that the goals were not met, the nurse modifies the care plan, creating a new cycle of assessment, diagnosis, planning, implementation, and re-evaluation. This continuous feedback loop ensures that care remains adaptable and effective.
ADPIE vs. Medical Process
| Feature | ADPIE (Nursing Process) | Medical Process (Physician) |
|---|---|---|
| Focus | Patient's holistic response to illness/condition | Identifying and treating the specific disease or condition |
| Diagnosis | Nursing diagnosis based on patient's human response | Medical diagnosis based on pathology and symptoms |
| Interventions | Directed at patient needs and holistic care (e.g., pain management, education) | Primarily focused on prescribing medications, surgery, and treating the disease |
| Goal | Achieve patient-centered outcomes, promote recovery | Cure or manage the disease |
| Cyclical | Continuous loop of assessment, intervention, and evaluation | Often episodic, focused on diagnosis and treatment rather than daily holistic needs |
The Role of Critical Thinking and Evidence-Based Practice
Throughout the ADPIE process, critical thinking is essential. Nurses must analyze data, synthesize information, and make sound clinical judgments to develop and implement effective care plans. Coupled with evidence-based practice (EBP), which integrates the best available research with clinical expertise, the nursing process ensures that all patient care is grounded in both knowledge and clinical experience.

Conclusion: A Guiding Framework for Quality Care
The ADPIE process—assessment, diagnosis, planning, implementation, and evaluation—is far more than a simple checklist. It represents a structured, yet flexible, framework that empowers nurses to deliver compassionate, high-quality, and patient-centered care. By systematically approaching each patient's unique needs, nurses can adapt to changing conditions and ensure the best possible outcomes for those under their care. This continuous, thoughtful process is what solidifies nursing as a skilled, critical profession within the broader healthcare system.
