Understanding the Core Nursing Process (ADPIE)
Before diving into the specific care delivery models, it's crucial to understand the foundation on which they are all built: the core nursing process, often remembered by the acronym ADPIE. This five-step, patient-centered framework guides nurses in delivering safe, effective, and continuous care.
Assessment
This first step involves systematically collecting comprehensive patient data. It includes both subjective information (verbal statements from the patient, such as symptoms) and objective information (measurable data like vital signs, lab results, and physical exam findings). The thoroughness of the assessment lays the groundwork for all subsequent steps.
Diagnosis
Based on the assessed data, the nurse formulates a nursing diagnosis. Unlike a medical diagnosis, which identifies a disease, a nursing diagnosis describes a patient's response to an actual or potential health problem. This clinical judgment helps to prioritize and plan patient-centered interventions.
Planning
During the planning phase, the nurse and patient collaborate to establish specific, measurable, achievable, relevant, and time-bound (SMART) goals. This stage involves creating a care plan that outlines the necessary nursing interventions to achieve the desired outcomes. Planning is a dynamic process that must be flexible and responsive to the patient's changing needs.
Implementation
This is the action-oriented step where the nurse carries out the interventions detailed in the care plan. Implementation can involve direct care (like medication administration or wound care) and indirect care (such as coordinating with other healthcare team members or documenting progress).
Evaluation
The final step involves continuously evaluating the effectiveness of the care plan and the patient's progress toward their goals. The evaluation data informs whether to continue, modify, or terminate the existing plan, ensuring that the care remains relevant and effective.
Four Distinct Types of Nursing Processes (Care Delivery Models)
The term "types of nursing processes" can sometimes refer to different care delivery models that structure how the core ADPIE process is executed within a healthcare setting. These models are frameworks used to organize the delivery of nursing care, each with its own advantages and disadvantages.
1. Functional Nursing
In this task-oriented model, a nurse manager assigns specific tasks to different staff members based on their skill level. For example, one nurse may be responsible for all medication administration on a unit, while another handles all the vital signs. This approach can be very efficient for a high volume of patients and is often used during staff shortages.
Key Features:
- Task-Based: Focuses on the completion of specific duties rather than on the holistic care of a single patient.
- Efficiency: Can speed up the completion of individual tasks.
- Potential for Fragmentation: Risk of fragmented, impersonal care, as no single nurse is responsible for a patient's total care during a shift.
2. Team Nursing
This model uses a collaborative approach where a team leader, typically a registered nurse (RN), coordinates care for a group of patients. The team consists of various nursing staff members, such as licensed practical nurses (LPNs) and certified nursing assistants (CNAs), with the team leader delegating tasks based on the scope of practice for each role.
Key Features:
- Collaborative: Fosters teamwork and shared responsibility for patient outcomes.
- Supervised Delegation: The team leader coordinates and supervises care, ensuring a cohesive approach.
- Shared Accountability: The whole team is accountable for the quality of care provided.
3. Primary Nursing
Also known as relationship-based practice, primary nursing assigns one RN to be responsible for a patient's total care from admission to discharge. This includes developing, implementing, and evaluating the care plan. When the primary nurse is not on duty, an associate nurse follows the established care plan to ensure continuity.
Key Features:
- Holistic Care: Promotes a strong nurse-patient relationship built on trust and continuity.
- Increased Accountability: The primary nurse is accountable for the entire care plan, leading to greater ownership of patient outcomes.
- Patient-Centered: This model is highly patient-centered, focusing on the individual's preferences and values.
4. Total Patient Care
In this model, one registered nurse provides all the nursing care for one or more patients during a single shift. The RN is responsible for assessment, planning, implementation, and evaluation, essentially providing a form of bedside nursing that is comprehensive and uninterrupted. This model is often used in settings where a patient's needs are complex and require a high level of continuous observation, such as intensive care units.
Key Features:
- Total Responsibility: The RN manages all aspects of care for their assigned patients during a shift.
- High Continuity: The patient benefits from the high level of focused attention from a single caregiver.
- High RN Staffing Needs: Requires a larger number of RNs per patient, which may not always be feasible.
Comparison of Nursing Care Delivery Models
| Feature | Functional Nursing | Team Nursing | Primary Nursing | Total Patient Care |
|---|---|---|---|---|
| Focus | Tasks | Group of Patients | Individual Patient | Individual Patient |
| Caregiver Type | Mixed skill levels | RN team leader with mixed staff | RN responsible 24/7 | RN provides all care for the shift |
| Strengths | Efficient for tasks, cost-effective | Collaborative, support system | Strong nurse-patient relationship, continuous care | High continuity, comprehensive care |
| Weaknesses | Fragmented care, less accountability | Delegation challenges, less continuity than primary | Higher cost, requires more RNs | High RN staffing needs, can be costly |
The Role of Critical Thinking and Evidence-Based Practice
Regardless of the care delivery model, the underlying principles of the nursing process remain the same. The ability to apply critical thinking and integrate evidence-based practice is what elevates the nursing process beyond a simple checklist of tasks. Nurses must continually analyze patient data, adapt care plans, and use their clinical judgment to ensure the best possible outcomes. The nursing process is not a rigid linear progression, but a dynamic, cyclic approach that requires a nurse to move back and forth between steps as a patient's condition changes.

Conclusion
While the ADPIE framework provides the standardized, systematic steps for patient care, different care delivery models—functional, team, primary, and total patient care—define how that process is organized within a healthcare setting. These models determine the structure of nursing roles and responsibilities, impacting patient-care continuity, staff collaboration, and efficiency. By understanding the advantages and disadvantages of each model, nurses and healthcare administrators can make informed decisions to optimize the delivery of care. The most effective approach is always the one that best suits the patient's needs and the available resources, ensuring a holistic and evidence-based practice is maintained throughout the process.
