Unit 4 Assignment

The unit, the vignettes and the staffing figures are composite; published evidence is cited where it exists, and ratings resting on reasoning alone are labeled as such.
Criteria, Fixed First
The criteria come directly from the population profile, so the comparison cannot drift toward whichever model the writer prefers. Four are needs: continuity across the admission, medication management, caregiver support and access to follow-up. Two are feasibility criteria, because a model that fits the patients but cannot be staffed or paid for has not been compared honestly: registered nurse staffing required, and cost.
Each cell below holds a rating, strong, partial or weak, and a sentence of reasoning. Where published evidence exists it is cited; where the rating rests on reasoning about how the model works, it says so.
Comparison Matrix
1. Continuity. Team nursing: weak. A patient staying five days meets several team leaders, and continuity depends on documents and handoffs; on many units nurse continuity is low, with a unit-level index far below the ideal (Stifter et al., 2015). Primary nursing: strong. One registered nurse is accountable from admission to discharge (Manthey, 2002), though continuity is interrupted on the primary nurse's days off.
2. Medication management. Team nursing: partial. Reconciliation and teaching happen, but often on the discharge morning and by a nurse new to the patient; rating based on the unit's record review. Primary nursing: partial to strong. The primary nurse can plan teaching across the stay and reconcile changes she has watched happen; rating based on reasoning, since no study directly compares the two models on medication errors after discharge.
3. Caregiver support. Team nursing: weak. No one is assigned to identify and teach the caregiver over several days. Primary nursing: strong in principle, since the primary nurse can schedule teaching for when the caregiver visits; rating based on reasoning.
4. Access and handoff to the clinic. Team nursing: weak. Primary nursing: weak. The primary nurse's accountability ends at discharge, and neither model, as defined, reaches the clinic; rating based on the unit's review, where most failures clustered before the first clinic contact.
5. Registered nurse staffing. Team nursing: strong fit for a mixed skill mix and shortages. Primary nursing: weak fit. It requires more registered nurses at the bedside, calculated in the appendix.
6. Cost. Team nursing: lower. Primary nursing: higher labor cost; the Cochrane review of staffing models found only very low certainty evidence on whether primary nursing reduces costs or staff turnover (Butler et al., 2019).
Vignette: One Admission Under Team Nursing
Mr. B., 80, is admitted on a Monday with heart failure and chronic kidney disease, his third admission this year. Across five days he is cared for by [four] team leaders, [three] licensed practical nurses and [five] assistants. His diuretic is changed on Tuesday and his potassium supplement stopped on Wednesday. His daughter visits in the evenings. Discharge teaching is done Friday morning by a licensed practical nurse who met him that day, with the team leader signing the instructions. The daughter is not present. The discharge summary is completed Friday afternoon.
Vignette: The Same Admission Under Primary Nursing
Mr. B.'s primary nurse admits him on Monday and is on duty Monday, Tuesday and Friday. On Wednesday and Thursday, associate nurses carry out her plan. She starts teaching on Tuesday, when the diuretic changes, and schedules a session with the daughter Tuesday evening. On Wednesday, an associate nurse stops the potassium supplement and documents the change for the primary nurse. On Friday, the primary nurse reviews the whole medication list with Mr. B. and, by phone, with his daughter. She has no scheduled role after he leaves.
The second vignette is better on continuity and caregiver teaching, but it has gaps of its own: two of five days are covered by associates, and the gap between the unit and the clinic is the same as in the first vignette.
What the Evidence Can and Cannot Settle
The published evidence cannot settle this comparison on its own. The Cochrane review of hospital staffing models found few studies of primary nursing, all with high risk of bias, and none that measured readmission (Butler et al., 2019). The skill-mix literature is largely cross-sectional and compares shares of professional nurses rather than models of assigning them. The continuity literature shows that continuity is often low but has not shown that it prevents harm once patient factors are considered (Stifter et al., 2015). What the evidence does support is the mechanism primary nursing claims: that accountability held by one nurse is more likely to catch the small changes, a stopped supplement, an absent caregiver, that the population profile found behind early readmissions. That is a reason to test the model on this population, not proof that it will work.
Mismatch Risks
Two features of the unit could undermine primary nursing. Twelve-hour shifts mean a primary nurse works about three days a week, so for a five-day stay she may be present for only three of them. And the unit's current skill mix has more licensed practical nurses than primary nursing can use in the associate role, since associates in primary nursing are usually registered nurses who can carry out and adjust the plan. Moving to primary nursing without addressing either would produce the model's name without its continuity.
Staffing Appendix
Primary nursing on one twelve-bed section, day shift: three registered nurses, each primary for four patients, plus two assistants; night shift: two registered nurses and one assistant. Current team nursing on the same section: one registered nurse, one licensed practical nurse and two assistants on days; one registered nurse, one licensed practical nurse and one assistant on nights. The change adds three registered nurse positions per day, two on days and one on nights, and removes two licensed practical nurse positions. Converting at about 2.1 full-time equivalents for each position staffed on one twelve-hour shift every day, that is about 6.3 additional registered nurse FTEs and 4.2 fewer licensed practical nurse FTEs.
Verdict
Primary nursing wins on continuity and caregiver support for this population, and it is at least as good on medication management. It loses on staffing and cost, and it does not solve the access problem, because its accountability ends at the door. The analysis therefore does not declare a winner for the whole unit. It supports a narrower proposal: primary nursing for the defined population on one section, paired with a change to the discharge handoff that reaches the clinic, which later units will design.

How this NU507 Unit 4 example is structured
Criteria are fixed before either model is scored, and they come straight from the population profile, which keeps the comparison from drifting toward whichever model the writer prefers. Two feasibility criteria sit beside the four needs because a model that fits patients but cannot be staffed has not been compared honestly. The vignettes do work the matrix cannot, showing what a model feels like across one admission, and they are balanced: primary nursing's vignette includes the days the primary nurse is off. Ratings carry sources where evidence exists and say plainly where they rest on reasoning alone. The staffing appendix keeps arithmetic out of the argument's flow while making it checkable. The conclusion does not declare a winner. It proposes primary nursing only for the defined population on one section, a bounded claim that the evidence review and transition plan can test.

NU507 Unit 4 questions, answered
Which two models should I compare?
Two that could realistically serve your population in your setting, ideally your current model and one credible alternative. Comparing a hospital unit model with a community payment arrangement mixes levels and rarely produces a decision. The sample compares team and primary nursing on the same unit, then notes that system-level options such as the medical home come into the later redesign.
How do I score models where evidence is thin?
Say so and score from reasoning, labeled as reasoning. Outcome research on nursing care delivery models is limited and often older, so many cells in any honest matrix rest on logic rather than trials. The sample marks each rating as evidence-based or reasoned, which lets the reader weigh them differently and prepares the ground for the evidence review.
Must the analysis choose one model?
Most rubrics want a conclusion, though it need not be a clean winner. A fit for a defined population, with limits, is a conclusion. The sample recommends primary nursing only for readmitted older adults on a single section, keeps team nursing elsewhere and names the staffing condition under which even that bounded choice would fail.
