Aaron W. Bonnett & Gregory Heim

As healthcare systems evolve to meet growing patient demands and rising costs, hospitals are increasingly relying on mid-level providers (MLPs) such as nurse practitioners and physician assistants. However, the long-term effects of this shift on hospital performance and costs have remained unclear. A recent study published in the Journal of Operations Management by Gregory Heim, professor and the Blue Bell Creameries Chair in Business at Texas A&M University’s Mays Business School, along with coauthor Aaron W. Bonnett (Sam Houston State University and former Texas A&M Ph.D. student), sheds light on this issue by exploring whether MLPs contribute to hospital cost efficiency or improve key performance outcomes known as Triple Aim Performance (TAP) metrics. This comprehensive research by Heim and Bonnett uses longitudinal data to assess how MLPs affect hospital outcomes related to clinical quality, technical efficiency, and patient experience. Their findings provide valuable insights for hospital administrators as they adapt their staffing models to meet operational challenges, offering a data-driven perspective on the impact of MLPs in healthcare delivery systems.

Unveiling the MLP Effect

This research delves into the complex relationship between MLP employment and hospital outcomes, focusing on cost per discharge and the TAP metrics: clinical quality, technical efficiency, and patient experience. By analyzing longitudinal data from 376 hospitals over four years, the study offers a nuanced perspective on the value MLPs bring to healthcare organizations.

Why This Matters

Understanding the impact of MLPs is crucial for:

  • Optimizing hospital staffing decisions
  • Balancing care quality with operational efficiency
  • Addressing physician shortages in a cost-effective manner

As healthcare systems grapple with rising costs and demands for improved patient outcomes, these insights could reshape staffing strategies.

Key Findings: Beyond Cost Reduction

The researchers uncovered several intriguing insights:

  1. Cost Neutrality: Contrary to common belief, increased MLP usage does not directly lower hospital costs per discharge.
  2. TAP Improvement: Higher percentages of MLPs are associated with better performance in clinical quality, technical efficiency, and patient experience.
  3. Holistic Excellence: Hospitals with more MLPs are more likely to excel across all TAP metrics simultaneously.
  4. Efficiency Variations: The impact of MLPs varies across different hospital efficiency levels, suggesting the need for tailored staffing approaches.

Methodology: A Data-Driven Approach

The researchers used data from the American Hospital Association (AHA) and CMS Impact Files to conduct their analysis, covering 1,504 hospital-year observations from 376 hospitals between 2011 and 2014. By applying data envelopment analysis (DEA) and panel regression models, the study evaluated the relationship between MLP usage and hospital performance metrics, offering a robust exploration of how staffing decisions impact both costs and efficiency.

Main Findings: Quality Over Cost Reduction

Several important findings emerged from the study:

  • MLPs do not reduce costs: The study found no significant association between the percentage of MLPs employed by a hospital and reductions in hospital cost per discharge. This challenges the common assumption that MLPs automatically lead to cost savings.
  • MLPs improve performance across TAP metrics: Hospitals with a higher proportion of MLPs performed better on clinical quality, technical efficiency, and patient experience. These findings suggest that while MLPs may not lower costs directly, they contribute to enhanced operational outcomes, making hospitals more efficient overall.
  • Higher MLP usage leads to excellence in all TAP areas: The study revealed that hospitals employing more MLPs are significantly more likely to excel across all three Triple Aim metrics.

A key takeaway from the study is that the strategic use of MLPs improves hospital performance, particularly in areas where quality and efficiency matter most, even if direct cost savings are not immediately realized.

Practical Implications: Reimagining Staffing Strategies

These findings offer valuable insights for healthcare administrators and policymakers:

  1. Shift in Focus: Instead of viewing MLPs primarily as cost-cutting measures, consider their role in enhancing overall care quality and efficiency.
  2. Balanced Staffing: Aim for an optimal mix of physicians and MLPs to maximize performance across all TAP metrics.
  3. Tailored Approaches: Recognize that the impact of MLPs may vary based on a hospital’s current efficiency level and other characteristics.
  4. Patient Experience: Leverage MLPs to improve patient satisfaction without compromising clinical quality.

Navigating Complexity in Healthcare Staffing

As the healthcare landscape continues to evolve, several questions emerge:

  • How might the role of MLPs change with advancements in telemedicine and AI-assisted diagnostics?
  • What training or support systems can maximize the positive impact of MLPs on hospital performance?
  • How can hospitals optimize their staffing mix to address specific areas of underperformance in TAP metrics?

The findings from this study can help hospital leaders make more informed decisions about workforce planning, ensuring that their staffing strategies align with the broader goals of improving healthcare quality and operational efficiency.

Conclusion: Rethinking the Role of MLPs in Healthcare

This study provides a fresh perspective on the role of mid-level providers in hospital operations, highlighting their ability to enhance clinical quality and efficiency, even if they do not directly reduce costs. As hospitals continue to adapt to evolving healthcare demands, the strategic deployment of MLPs can play a critical role in meeting performance goals, particularly when aiming to achieve excellence across the Triple Aim framework.

For hospital administrators, MLPs are not simply a cost-saving measure but a strategic asset in achieving excellence across multiple dimensions of care. As healthcare systems continue to navigate the complex interplay between cost, quality, and patient satisfaction, this research provides a valuable roadmap for leveraging MLPs to enhance overall hospital performance.

In an era where healthcare excellence is defined by more than just the bottom line, this study reminds us that true efficiency in hospital operations comes from a holistic approach to staffing and care delivery.
