A large new study from Penn Nursing compared outcomes at for-profit and nonprofit hospitals and found that patients at for-profit hospitals were more likely to die or come back within 30 days, and that thinner nurse staffing was one of the main threads tying those results together. Seven in ten nurses at those hospitals said their assignments were not safe.
What happened
On October 7, 2026, the University of Pennsylvania School of Nursing announced the paper “Patient Outcomes and Nurse Understaffing in For-Profit Hospitals,” published open access in the journal Medical Care. The team, led by Matthew D. McHugh with Karen B. Lasater, K. Jane Muir, Trissa Lyman, Angelo Petto and Linda H. Aiken, comes from Penn’s Center for Health Outcomes and Policy Research. The work was funded by the National Institute of Nursing Research at the NIH.
The researchers looked at more than 1.17 million patients in 143 for-profit and 798 nonprofit adult acute care hospitals across 10 states. Compared with nonprofit hospitals, for-profit hospitals had:
- about 11 more deaths per 1,000 medical admissions and about 5 more per 1,000 surgical admissions;
- 30-day readmission rates 2.04 percentage points higher for medical patients and 1.76 points higher for surgical patients (roughly 20 and 18 more readmissions per 1,000 discharges);
- lower patient ratings of their care.
Nurse staffing was described as a main explanation for the mortality gap. For readmissions, staffing explained 16% of the difference for medical patients and 30% for surgical patients. Nurses at for-profit hospitals also reported significantly more burnout and were much less likely to recommend their hospital as a place to get care or to work. McHugh summed up the policy ask in one line: “Minimum safe staffing requirements and ownership transparency are practical safeguards for patients and nurses.”
One important caution: this is an observational study. It shows that for-profit ownership and understaffing are linked to worse outcomes. It does not prove that ownership type causes them, and many individual for-profit hospitals staff well.
Why it matters at the bedside
Workload is not only a morale issue. It is a patient-safety variable. Every extra patient on an assignment stretches the time between reassessments. That gap is where early warning signs get missed: a respiratory rate creeping up, new confusion, a urine output that has quietly dropped. Researchers call the result failure to rescue, when a complication is not recognized and treated in time.
Readmissions tell a similar story from the other end of the stay. Discharge teaching takes time: checking that the patient can explain the new medications, the warning signs to watch for and when to call. On a heavy assignment, that teaching is the first thing to get rushed, and the readmission numbers in this study are consistent with that.
None of this means a nurse on a heavy assignment is doing anything wrong. It means the nurse has to triage constantly, and that is a skill you can build on purpose.

Management of care is one of the most heavily weighted areas on the NCLEX-RN, and this study is a real-world version of those questions. Expect items that hand you four patients and ask who you see first, which task you can delegate to unlicensed assistive personnel, or which patient should not go to the newest nurse.
- Unstable before stable. Use the ABCs (airway, breathing, circulation) and acute versus chronic to decide who is seen first.
- Delegate within scope. Assessment, teaching and evaluation stay with the RN. Stable, routine, predictable tasks can go to UAP.
- Unexpected findings come first. A change from baseline outranks an expected finding, even when the expected finding looks more dramatic on paper.
The study is also a good example of evidence-based practice in action. Staffing laws and hospital policies are often built on exactly this kind of outcomes research, which is why it helps to know the difference between an association and a proven cause when you read it.
Try it on NurseSavvyABCs Framework for Prioritization →The one sequence that decides who you see first, on the unit and on the exam.What to do now
- Students: practice prioritization sets with four or more patients, and say out loud why each patient lands where they do.
- Job seekers: ask every unit you interview with about its typical day and night ratios, how often nurses float, whether the charge nurse takes patients, and who owns the hospital.
- Comparing offers: put pay, differentials and benefits side by side, then weigh staffing on top of the numbers. The better-staffed unit can be worth more than a higher base rate.
- On shift: if an assignment is unsafe, raise it through the chain of command and follow your facility’s process for documenting staffing concerns.
Common questions
Did the study prove that for-profit ownership causes worse outcomes?
No. It is an observational study, so it shows an association. For-profit hospitals had higher mortality and readmissions, and differences in nurse staffing explained part of that gap, but the design cannot prove cause and effect.
What share of nurses at for-profit hospitals said their workload was unsafe?
According to the Penn Nursing news release, 71% of nurses working in for-profit hospitals said their assigned patient workloads were not safe.
How does this connect to the NCLEX?
The NCLEX tests management of care: making assignments, prioritizing unstable patients first, and delegating within scope. Those are the skills that keep patients safe when the assignment is heavy.
