A nursing care delivery model (also called a nursing care delivery system or patterns of nursing care assignment) is the way a unit organizes and assigns nursing work: who plans care, who gives it, who makes decisions, and who is accountable for each client. The model affects quality, safety, continuity, cost, and nurse and client satisfaction.

Every model answers four questions:

1. Who makes clinical decisions for the client, and for how long (one shift, or the whole stay)?
2. How is work assigned — by task, by client, or by geographic area?
3. How is communication handled — through the charge nurse, a team leader, or directly?
4. Who is accountable for the outcome of care?

Historical sequence (commonly tested): the case method (total patient care) is the oldest model, from private-duty nursing → functional nursing grew during nursing shortages around World War II → team nursing was developed in the 1950s to reduce fragmentation → primary nursing appeared in the late 1960s–1970s to restore continuity and accountability → case management and related outcome-focused models (patient-focused care, differentiated practice) spread from the 1980s onward.

Choosing a model. Match the model to:

• Client factors — acuity, complexity, length of stay
• Staff factors — number of nurses, experience, and the mix of nurses to nursing attendants (skill mix)
• Organizational factors — budget, ward layout, philosophy of nursing, documentation system
• Quality goals — continuity, safety, satisfaction

Preceptorship is not a delivery model for clients; it is a staff development arrangement in which an experienced nurse teaches and supervises a new nurse or student one-to-one while they share an assignment. It is often used alongside whatever model the unit runs.

Common Philippine ward reality. With high patient loads, many wards use a team or functional pattern with a charge nurse, one or more medication nurses, and nursing attendants. Intensive care units and some specialty units use total patient care. Understanding the weaknesses of each model helps nurses protect safety:

• In functional patterns, assign one nurse per client group to own the overall assessment and escalation so deterioration is not missed between task-givers.
• In team nursing, the team leader holds a brief team conference at the start of the shift: priorities, who is at risk, what each member must report back and when.
• In all models, the shift endorsement (handoff) is the main safety link. Use a structured format (for example, SBAR — Situation, Background, Assessment, Recommendation), endorse at the bedside when possible, and include pending tests, drips, due medications, fall and pressure-injury risk, and unresolved concerns.

Team leader responsibilities (commonly tested):

• Assess the clients in the group and set priorities
• Develop and update nursing care plans
• Assign tasks to members according to their competence and the client's needs
• Supervise, coach, and check the work of members, especially nursing attendants
• Communicate with the charge nurse, physicians, and other departments
• Evaluate outcomes and hold team conferences

Primary nurse responsibilities: perform the admission assessment, write and own the plan of care, coordinate with the health team and family, plan discharge from day one, and communicate with associate nurses. The primary nurse does not work 24 hours, but remains accountable for the plan 24 hours a day; the nurse on duty is responsible for the care actually given that shift.

• Head nurse / nurse manager: select a model that fits acuity, staffing, and budget; define who is accountable for each client each shift; train team leaders; monitor outcomes such as falls, medication errors, pressure injuries, and client satisfaction.
• Charge nurse: make assignments that match competence and acuity; balance workload; act as the escalation point.
• Team leader / primary nurse: plan, assign, supervise, evaluate.
• Staff nurse / associate nurse: carry out the plan, report changes promptly, and document.
• All registered nurses: supervise nursing attendants and never assign them tasks that require nursing assessment, judgment, or evaluation.

• Scope of practice. Under the Philippine Nursing Act of 2002 (RA 9173, Section 28), nursing functions — assessment, planning, health teaching, and administering medications and treatments as ordered — belong to registered nurses. Nursing attendants and other unlicensed staff may help with routine care only under a nurse's supervision; they must not do tasks that require a nurse's license and judgment.
• Accountability is individual. In functional or team models, "many people were involved" is not a defense. Each nurse is accountable for the care they personally give, and the nurse who assigns or supervises is accountable for the appropriateness of the assignment and the supervision.
• Documentation and endorsement. Incomplete endorsement that leads to harm can support a claim of negligence. Document assessments, interventions, and communication with the physician.
• Confidentiality. Bedside endorsement must protect privacy; client information is sensitive personal information under the Data Privacy Act of 2012 (RA 10173).
• Ethics. Fragmented, task-only care can fail the principle of beneficence; leaders should choose models that allow nurses to see the whole person.

Case 1 — Recognizing functional nursing. On a medical ward, one nurse gives all medications, another does all dressings and IV checks, and nursing attendants take all vital signs. A client's rising temperature and new confusion are noticed by three different workers, but no one connects them. Model: functional. Correct action: the charge nurse assigns one nurse to own each client group's assessment and escalation. Why: the key weakness of functional nursing is fragmented care with unclear accountability.

Case 2 — Team leader priority. At the start of the shift, a team leader has 14 clients, one staff nurse, and two nursing attendants. Correct action: quickly assess or receive endorsement on the most unstable clients first, then hold a short team conference, assigning the nurse to clients needing medications and assessment and the attendants to stable clients' hygiene, feeding, and ambulation with clear report-back rules. Why: the team leader plans, assigns by competence, and supervises.

Case 3 — Primary nursing continuity. The primary nurse of a client with a new colostomy is on days off. The associate nurse notices that stoma teaching has not started and discharge is in two days. Correct action: begin teaching according to the plan, update the plan, communicate with the primary nurse, and document. Why: the primary nurse is accountable for the plan, but the nurse on duty is responsible for care given in that shift.

Case 4 — Case management goal. A hospital introduces a nurse case manager for clients having hip replacement, using a clinical pathway. The ultimate goal is quality outcomes at controlled cost — timely care, fewer complications, and appropriate length of stay.

• Calling functional nursing "patient-centered" — it is task-centered.
• Saying accountability is clear in functional nursing — it is unclear; clear accountability is a strength of total patient care and primary nursing.
• Believing the primary nurse must be physically present 24 hours — the accountability is 24 hours, not the presence.
• Confusing team nursing (a nursing team led by a nurse) with an interdisciplinary team (nurses, physicians, therapists, social workers).
• Treating modular nursing as a separate philosophy — it is team nursing organized by geography.
• Listing preceptorship as a client care delivery model — it is a staff orientation method.
• Getting the history wrong: total patient care is the oldest model, not functional nursing.

• Total patient care = one nurse, all care, for the shift; oldest model; used in ICU; costly.
• Functional = by task; efficient and cheap; fragmented; accountability unclear.
• Team = nurse team leader plans, assigns, supervises; team conference is key.
• Modular = small team assigned to a geographic area of the ward.
• Primary = 24-hour accountability from admission to discharge; associate nurses follow the plan.
• Case management = coordinates quality, cost, and outcomes across the episode, often with clinical pathways.
• Choose a model by client acuity, staff numbers and skill mix, budget, and quality goals.
• Historical order: case method → functional → team → primary → case management.
• Structured endorsement (e.g., SBAR) is the main safety link in every model.
• Nurses remain accountable for supervising nursing attendants; tasks needing assessment and judgment stay with the nurse (RA 9173 Section 28).
