Assembly-Line Nursing Was Meant to Be Temporary

There's a nursing model where one nurse passes medications to every patient on the unit and does nothing else. Another nurse does treatments. An aide does baths and vital signs. Nobody is responsible for a patient. Everybody is responsible for a task. Nursing textbooks call it assembly line nursing.

The formal name is functional nursing. But the assembly-line description is not something critics invented. In their 2004 review of nursing care delivery models, Tiedeman and Lookinland wrote that functional nursing places priority on physicians' orders and the procedures needed to carry them out “with an assembly line approach to care.”

So when I argue that “assembly line medicine” is a bad description of how bad hospitals run, I should acknowledge that American nursing has a history with a model that genuinely fits the description. It is the clearest real example behind the phrase.

Where Assembly Line Nursing Came From

Functional nursing spread during World War II. Nurses joined the armed forces, leaving hospitals short-staffed. Hospitals responded by bringing in more LPNs and unlicensed aides and dividing the work by license level.

Each person did their assigned task for every patient on the unit. Proficiency came from repetition.

It was supposed to be temporary. Nurses would return from the war, and hospitals would return to their previous model of care. In a 2004 review of care delivery models, Tiedeman and Lookinland note that functional nursing persisted because it managed time, tasks, and people efficiently during a period of growing demand.

The criticism showed up early, and it is still in the textbooks. One nursing leadership text explains:

“When implementing functional nursing, the focus is on the task and not necessarily holistic client care.”

The authors add that continuity of care is lost and that reassessment, follow-up, and communication can break down, and “little time is devoted to the psychosocial and spiritual needs of the patient.”

Nurses are trained to care for a patient. Functional nursing gives each of them a task instead.

That is a real grievance about real work design, and it is eighty years old.

Whether Anybody Copied a Factory Is Less Clear

A 2021 review in the International Journal of Environmental Research and Public Health traces nursing work methods against management theory and draws the line to Frederick Taylor directly, noting that scientific management called for dividing work into specific sections under a single supervisor.

The parallel is obvious. Evidence that hospitals consciously adopted Taylor's model is harder to find, and I haven't found it.

I suspect the explanation is simpler. When an organization is short on skilled people and overwhelmed with work, dividing tasks by skill level is an obvious response. You don't need to have read Taylor. You need a unit full of patients and not enough nurses.

That distinction matters. If hospitals arrived at this factory-like model independently, under pressure, blaming industry for it repeats the mistake I've been arguing against. The idea didn't come from Detroit. It came from the situation.

The Other Thing That Showed Up

The same war brought a second industrial import into hospitals, and this one has a paper trail.

Training Within Industry was created by the War Department and ran from 1940 to 1945 inside the War Manpower Commission. It addressed the same problem hospitals faced: skilled workers were being conscripted just as demand increased.

TWI initially centered on three programs. Job Instruction taught supervisors how to teach a job effectively. Job Methods taught them to break down the work and combine, rearrange, and simplify it. Job Relations taught them how to handle problems with people.

Hospitals adopted Job Instruction first, using it to prepare other workers to take routine duties from overtaxed nurses. Job Methods and Job Relations followed, through the War Manpower Commission's regional offices.

Walter Dietz of TWI published two articles in May 1945. One appeared in the American Journal of Nursing, titled “TWI Can Help Solve Nurse Power Problems: New Needs for On-the-Job Training in Hospitals.” The other ran in Hospitals, and it was called “Those Who Supervise Should Remember That All Workers Have Feelings.“

In the month Germany surrendered, the hospital administration literature was reminding supervisors that workers had feelings. That might be worth re-writing for 2026.

Same Crisis, Two Answers

Both of these arrived in American hospitals during the same war, in response to the same shortage, out of the same industrial world.

One split the work into tasks and handed nurses a fragment. The other taught supervisors how to train people effectively and handle workplace relationships more fairly.

One appears in nursing textbooks as a cautionary tale about assembly-line care. I had to go looking for the other.

Nobody who says “assembly line medicine” is thinking of Walter Dietz. And when a nurse tells me that industrial thinking damaged her profession, she's pointing at something real. But she is pointing to only one of the industrial responses that entered hospitals during the war–and to the one that persisted.

What Actually Fixed It

The correction didn't come from rejecting industry. It came from a manager listening to a unit.

In 1968, on Unit 32 at University of Minnesota Hospital, a group of nurses were fed up with how chaotic their work had become. Marie Manthey was assistant director of nursing at the time. What came out of that unit was primary nursing: one nurse responsible for a patient from admission to discharge, accountable for the plan of care, with support from the rest of the team.

It spread worldwide. Manthey spent the rest of her career on it and died in December 2024. There's a plaque in the Mayo Memorial Building at Minnesota marking where Station 32 was. She also recorded an oral history about Station 32 and the changing roles of RNs and LPNs.

What matters here is who initiated the change. Not a consultant, not an executive with a mandate, not a professional association resolution. The people doing the work said, “This is chaos,” and a manager gave them room to redesign it.

The Part I Can't Answer

Functional nursing was supposed to end when the nurses came home.

I can't find anybody who decided to keep it. It apparently worked well enough to continue, year after year. Eighty years later, it remains in use in some settings and appears in nursing textbooks as a model of what went wrong.

That's a different problem from the one I wrote about lin July. In that case, someone approved the block schedule and someone designed the staffing model. Those decisions had identifiable owners. Here, the trouble is that nobody signed anything. A wartime workaround aged into a standard practice because no one ever revisited it.

Hospitals are short-staffed again. What are we doing now that we would call temporary if anyone stopped to ask?
