Why This Research Matters
This research project, titled 'Identifying Nursing Models of Care to Improve Emergency Department Patient Outcomes,' aims to understand how different ways nurses are organized and supported in hospital emergency departments (EDs) can affect patient results. The main goal is for Dr. K. Jane Muir to become an independent researcher by learning advanced methods like machine learning and causal inference, which will help her find out what makes nursing care effective.
The study focuses on a big problem: EDs are often very busy and chaotic, leading to delays in care and sometimes worse outcomes for patients, especially those with Medicaid or no insurance. Nurses play a crucial role in managing everything that happens in an ED—from deciding who needs urgent help (triage) to making sure patients leave the hospital properly (disposition). However, it's not clear if nurses have enough resources or support to do their jobs well.
The research has two main parts. First, it will use machine learning on large datasets—including surveys of nurses from multiple states, information about hospitals, and patient records—to find out which combinations of nursing resources (like how many nurses are there, what kind of environment they work in, the mix of skills among staff, or if nurse practitioners are involved) lead to better ED outcomes. These outcomes include things like how long a patient stays in the ED, whether they come back soon after leaving, if they leave against medical advice, and their chances of being readmitted to the hospital within 30 days or dying while still in the hospital.
Second, it will look at these nursing models specifically for different groups of patients. The study wants to see if certain nursing approaches work better for some patient populations than others, particularly those who might face more challenges accessing care.
This project is funded by a grant from the National Institute of Nursing Research (NINR) and is based at the University of Pennsylvania School of Nursing. Dr. Muir has an experienced team to guide her through this training and research journey.

Study Overview
Candidate: To achieve her career goal of becoming an independent investigator, K. Jane Muir, PhD, APRN, FNP-BC seeks mentored research training in population health research, machine learning techniques, and causal inference approaches. This career development award identifies modifiable nursing features to improve emergency department (ED) patient outcomes with a focus on reducing differences in clinical outcomes. Research Context: Hospital EDs have the potential to save lives, but pervasive delays and chaotic aspects of emergency care place patient’s health outcomes at risk while widening differences in care among patients with Medicaid or without insurance. Registered nurses direct all processes of care in hospital EDs including triage, throughput, and patient disposition, yet few studies have determined whether they are adequately resourced to do so. This study aims to determine the extent to which hospital nursing models of care are associated with patient outcomes to improve ED care. Specific Aims. 1) To determine which nursing models of care (defined by different combinations of ED and inpatient nursing resources) are associated with ED patient outcomes; 2) To determine the association of nursing models of care on ED patient outcome differences. Research Plan: Datasets include, 1) Penn’s Nurses4All multi-state nurse survey, 2) the American Hospital Association Annual Hospital Survey, 3) AHRQ Healthcare Cost Utilization Project patient database. In Aim 1, machine learning will be used to identify nursing models of care characterized by ED and inpatient nursing resources (nurse staffing levels, nurse work environments, skill mix, nurse practitioners) associated with ED patient outcomes (ED length of stay, ED revisits, disposition against medical advice, 30-day hospital readmissions, in-hospital mortality) in hospitals overall with separate comparisons among hospitals of differing disproportionate share (DSH) status. In Aim 2, differences in ED patient outcomes associated with nursing models of care will be examined across populations. Career Development Plan: With an interdisciplinary and experienced team of mentors, Dr. Muir will pursue didactics, seminars and conferences to complete the training goals, which are to 1) cultivate and apply expertise in the theory, design, and evaluation of research advancing population health; 2) apply advanced machine learning techniques to develop hospital nursing models of care defined by combinations of ED and inpatient nursing resources; 3) expand and apply skills in causal inference approaches with observational data. Environment: The University of Pennsylvania School of Nursing offers an ideal environment to pursue the proposed training and research. Dr. Muir is well-positioned to successfully complete the proposed aims and training because of her experienced mentorship team and extensive resources for career development.

Faculty notes
Educational Relevance
The provided metadata outlines a significant career development award for K. Jane Muir, PhD, APRN, FNP-BC, aimed at establishing her as an independent investigator in population health research, machine learning techniques, and causal inference approaches within the context of nursing care models. The project's core objective is to identify modifiable nursing features that can improve emergency department (ED) patient outcomes, with a specific focus on reducing disparities among patients with Medicaid or without insurance.
The research plan leverages three key datasets: Penn’s Nurses4All multi-state nurse survey, the American Hospital Association Annual Hospital Survey, and AHRQ Healthcare Cost Utilization Project patient database. The first aim employs machine learning to identify nursing models of care characterized by ED and inpatient nursing resources (staffing levels, work environments, skill mix, presence of nurse practitioners) associated with a range of ED patient outcomes (length of stay, revisits, disposition against medical advice, 30-day readmissions, mortality). This analysis will be conducted across all hospitals, with separate comparisons among hospitals differing in their Disproportionate Share Hospital (DSH) status. The second aim examines differences in these ED patient outcomes associated with nursing models of care specifically across various patient populations.
The career development plan is robust, involving didactics, seminars, and conferences under the guidance of an interdisciplinary mentorship team at the University of Pennsylvania School of Nursing. Dr. Muir's training goals include cultivating expertise in population health research design and evaluation, applying advanced machine learning for developing hospital nursing models, and expanding skills in causal inference with observational data. The project is well-positioned due to its experienced team and extensive resources.
Critical appraisal
Limitations
- The abstract primarily describes a research plan rather than presenting completed findings; therefore, specific results or conclusions are not available for discussion. Claims about limitations must be cautious as the project is in its development phase.
- While datasets like Nurses4All and AHRQ HCP are robust, potential limitations could arise from data quality issues inherent in large-scale surveys or observational databases (e.g., self-reporting bias, missing data).
- The study's reliance on observational data means that while associations between nursing models and outcomes can be identified, establishing definitive causal relationships requires careful application of advanced statistical methods like those mentioned for causal inference.
